+#
+#
+# This file enables PCRE2 to be built with the CMake configuration and build
+# tool. Download CMake in source or binary form from http://www.cmake.org/
+# Converted to support PCRE2 from the original PCRE file, August 2014.
+#
+# Original listfile by Christian Ehrlicher <Ch.Ehrlicher@gmx.de>
+# Refined and expanded by Daniel Richard G. <skunk@iSKUNK.ORG>
+# 2007-09-14 mod by Sheri so 7.4 supported configuration options can be entered
+# 2007-09-19 Adjusted by PH to retain previous default settings
+# 2007-12-26 (a) On UNIX, use names libpcre instead of just pcre
+# (b) Ensure pcretest and pcregrep link with the local library,
+# not a previously-installed one.
+# (c) Add PCRE_SUPPORT_LIBREADLINE, PCRE_SUPPORT_LIBZ, and
+# PCRE_SUPPORT_LIBBZ2.
+# 2008-01-20 Brought up to date to include several new features by Christian
+# Ehrlicher.
+# 2008-01-22 Sheri added options for backward compatibility of library names
+# when building with minGW:
+# if "ON", NON_STANDARD_LIB_PREFIX causes shared libraries to
+# be built without "lib" as prefix. (The libraries will be named
+# pcre.dll, pcreposix.dll and pcrecpp.dll).
+# if "ON", NON_STANDARD_LIB_SUFFIX causes shared libraries to
+# be built with suffix of "-0.dll". (The libraries will be named
+# libpcre-0.dll, libpcreposix-0.dll and libpcrecpp-0.dll - same names
+# built by default with Configure and Make.
+# 2008-01-23 PH removed the automatic build of pcredemo.
+# 2008-04-22 PH modified READLINE support so it finds NCURSES when needed.
+# 2008-07-03 PH updated for revised UCP property support (change of files)
+# 2009-03-23 PH applied Steven Van Ingelgem's patch to change the name
+# CMAKE_BINARY_DIR to PROJECT_BINARY_DIR so that it works when PCRE
+# is included within another project.
+# 2009-03-23 PH applied a modified version of Steven Van Ingelgem's patches to
+# add options to stop the building of pcregrep and the tests, and
+# to disable the final configuration report.
+# 2009-04-11 PH applied Christian Ehrlicher's patch to show compiler flags that
+# are set by specifying a release type.
+# 2010-01-02 PH added test for stdint.h
+# 2010-03-02 PH added test for inttypes.h
+# 2011-08-01 PH added PCREGREP_BUFSIZE
+# 2011-08-22 PH added PCRE_SUPPORT_JIT
+# 2011-09-06 PH modified WIN32 ADD_TEST line as suggested by Sergey Cherepanov
+# 2011-09-06 PH added PCRE_SUPPORT_PCREGREP_JIT
+# 2011-10-04 Sheri added support for including coff data in windows shared libraries
+# compiled with MINGW if pcre.rc and/or pcreposix.rc are placed in
+# the source dir by the user prior to building
+# 2011-10-04 Sheri changed various add_test's to use exes' location built instead
+# of DEBUG location only (likely only matters in MSVC)
+# 2011-10-04 Sheri added scripts to provide needed variables to RunTest and
+# RunGrepTest (used for UNIX and Msys)
+# 2011-10-04 Sheri added scripts to provide needed variables and to execute
+# RunTest.bat in Win32 (for effortless testing with "make test")
+# 2011-10-04 Sheri Increased minimum required cmake version
+# 2012-01-06 PH removed pcre_info.c and added pcre_string_utils.c
+# 2012-01-10 Zoltan Herczeg added libpcre16 support
+# 2012-01-13 Stephen Kelly added out of source build support
+# 2012-01-17 PH applied Stephen Kelly's patch to parse the version data out
+# of the configure.ac file
+# 2012-02-26 PH added support for libedit
+# 2012-09-06 PH added support for PCRE_EBCDIC_NL25
+# 2012-09-08 ChPe added PCRE32 support
+# 2012-10-23 PH added support for VALGRIND and GCOV
+# 2012-12-08 PH added patch from Daniel Richard G to quash some MSVC warnings
+# 2013-07-01 PH realized that the "support" for GCOV was a total nonsense and
+# so it has been removed.
+# 2013-10-08 PH got rid of the "source" command, which is a bash-ism (use ".")
+# 2013-11-05 PH added support for PARENS_NEST_LIMIT
+# 2014-08-29 PH converted the file for PCRE2 (which has no C++).
+# 2015-04-24 PH added support for PCRE2_DEBUG
+# 2015-07-16 PH updated for new pcre2_find_bracket source module
+# 2015-08-24 PH correct C_FLAGS setting (patch from Roy Ivy III)
+# 2015-10=16 PH added support for never-backslash-C

+Change Log for PCRE2
+--------------------
+
+Version 10.21 12-January-2016
+-----------------------------
+
+1. Improve matching speed of patterns starting with + or * in JIT.
+
+2. Use memchr() to find the first character in an unanchored match in 8-bit
+mode in the interpreter. This gives a significant speed improvement.
+
+3. Removed a redundant copy of the opcode_possessify table in the
+pcre2_auto_possessify.c source.
+
+4. Fix typos in dftables.c for z/OS.
+
+5. Change 36 for 10.20 broke the handling of [[:>:]] and [[:<:]] in that
+processing them could involve a buffer overflow if the following character was
+an opening parenthesis.
+
+6. Change 36 for 10.20 also introduced a bug in processing this pattern:
+/((?x)(*:0))#(?'/. Specifically: if a setting of (?x) was followed by a (*MARK)
+setting (which (*:0) is), then (?x) did not get unset at the end of its group
+during the scan for named groups, and hence the external # was incorrectly
+treated as a comment and the invalid (?' at the end of the pattern was not
+diagnosed. This caused a buffer overflow during the real compile. This bug was
+discovered by Karl Skomski with the LLVM fuzzer.
+
+7. Moved the pcre2_find_bracket() function from src/pcre2_compile.c into its
+own source module to avoid a circular dependency between src/pcre2_compile.c
+and src/pcre2_study.c
+
+8. A callout with a string argument containing an opening square bracket, for
+example /(?C$[$)(?<]/, was incorrectly processed and could provoke a buffer
+overflow. This bug was discovered by Karl Skomski with the LLVM fuzzer.
+
+9. The handling of callouts during the pre-pass for named group identification
+has been tightened up.
+
+10. The quantifier {1} can be ignored, whether greedy, non-greedy, or
+possessive. This is a very minor optimization.
+
+11. A possessively repeated conditional group that could match an empty string,
+for example, /(?(R))*+/, was incorrectly compiled.
+
+12. The Unicode tables have been updated to Unicode 8.0.0 (thanks to Christian
+Persch).
+
+13. An empty comment (?#) in a pattern was incorrectly processed and could
+provoke a buffer overflow. This bug was discovered by Karl Skomski with the
+LLVM fuzzer.
+
+14. Fix infinite recursion in the JIT compiler when certain patterns such as
+/(?:|a|){100}x/ are analysed.
+
+15. Some patterns with character classes involving [: and \\ were incorrectly
+compiled and could cause reading from uninitialized memory or an incorrect
+error diagnosis. Examples are: /[[:\\](?<[::]/ and /[[:\\](?'abc')[a:]. The
+first of these bugs was discovered by Karl Skomski with the LLVM fuzzer.
+
+16. Pathological patterns containing many nested occurrences of [: caused
+pcre2_compile() to run for a very long time. This bug was found by the LLVM
+fuzzer.
+
+17. A missing closing parenthesis for a callout with a string argument was not
+being diagnosed, possibly leading to a buffer overflow. This bug was found by
+the LLVM fuzzer.
+
+18. A conditional group with only one branch has an implicit empty alternative
+branch and must therefore be treated as potentially matching an empty string.
+
+19. If (?R was followed by - or + incorrect behaviour happened instead of a
+diagnostic. This bug was discovered by Karl Skomski with the LLVM fuzzer.
+
+20. Another bug that was introduced by change 36 for 10.20: conditional groups
+whose condition was an assertion preceded by an explicit callout with a string
+argument might be incorrectly processed, especially if the string contained \Q.
+This bug was discovered by Karl Skomski with the LLVM fuzzer.
+
+21. Compiling PCRE2 with the sanitize options of clang showed up a number of
+very pedantic coding infelicities and a buffer overflow while checking a UTF-8
+string if the final multi-byte UTF-8 character was truncated.
+
+22. For Perl compatibility in EBCDIC environments, ranges such as a-z in a
+class, where both values are literal letters in the same case, omit the
+non-letter EBCDIC code points within the range.
+
+23. Finding the minimum matching length of complex patterns with back
+references and/or recursions can take a long time. There is now a cut-off that
+gives up trying to find a minimum length when things get too complex.
+
+24. An optimization has been added that speeds up finding the minimum matching
+length for patterns containing repeated capturing groups or recursions.
+
+25. If a pattern contained a back reference to a group whose number was
+duplicated as a result of appearing in a (?|...) group, the computation of the
+minimum matching length gave a wrong result, which could cause incorrect "no
+match" errors. For such patterns, a minimum matching length cannot at present
+be computed.
+
+26. Added a check for integer overflow in conditions (?(<digits>) and
+(?(R<digits>). This omission was discovered by Karl Skomski with the LLVM
+fuzzer.
+
+27. Fixed an issue when \p{Any} inside an xclass did not read the current
+character.
+
+28. If pcre2grep was given the -q option with -c or -l, or when handling a
+binary file, it incorrectly wrote output to stdout.
+
+29. The JIT compiler did not restore the control verb head in case of *THEN
+control verbs. This issue was found by Karl Skomski with a custom LLVM fuzzer.
+
+30. The way recursive references such as (?3) are compiled has been re-written
+because the old way was the cause of many issues. Now, conversion of the group
+number into a pattern offset does not happen until the pattern has been
+completely compiled. This does mean that detection of all infinitely looping
+recursions is postponed till match time. In the past, some easy ones were
+detected at compile time. This re-writing was done in response to yet another
+bug found by the LLVM fuzzer.
+
+31. A test for a back reference to a non-existent group was missing for items
+such as \987. This caused incorrect code to be compiled. This issue was found
+by Karl Skomski with a custom LLVM fuzzer.
+
+32. Error messages for syntax errors following \g and \k were giving inaccurate
+offsets in the pattern.
+
+33. Improve the performance of starting single character repetitions in JIT.
+
+34. (*LIMIT_MATCH=) now gives an error instead of setting the value to 0.
+
+35. Error messages for syntax errors in *LIMIT_MATCH and *LIMIT_RECURSION now
+give the right offset instead of zero.
+
+36. The JIT compiler should not check repeats after a {0,1} repeat byte code.
+This issue was found by Karl Skomski with a custom LLVM fuzzer.
+
+37. The JIT compiler should restore the control chain for empty possessive
+repeats. This issue was found by Karl Skomski with a custom LLVM fuzzer.
+
+38. A bug which was introduced by the single character repetition optimization
+was fixed.
+
+39. Match limit check added to recursion. This issue was found by Karl Skomski
+with a custom LLVM fuzzer.
+
+40. Arrange for the UTF check in pcre2_match() and pcre2_dfa_match() to look
+only at the part of the subject that is relevant when the starting offset is
+non-zero.
+
+41. Improve first character match in JIT with SSE2 on x86.
+
+42. Fix two assertion fails in JIT. These issues were found by Karl Skomski
+with a custom LLVM fuzzer.
+
+43. Correct the setting of CMAKE_C_FLAGS in CMakeLists.txt (patch from Roy Ivy
+III).
+
+44. Fix bug in RunTest.bat for new test 14, and adjust the script for the added
+test (there are now 20 in total).
+
+45. Fixed a corner case of range optimization in JIT.
+
+46. Add the ${*MARK} facility to pcre2_substitute().
+
+47. Modifier lists in pcre2test were splitting at spaces without the required
+commas.
+
+48. Implemented PCRE2_ALT_VERBNAMES.
+
+49. Fixed two issues in JIT. These were found by Karl Skomski with a custom
+LLVM fuzzer.
+
+50. The pcre2test program has been extended by adding the #newline_default
+command. This has made it possible to run the standard tests when PCRE2 is
+compiled with either CR or CRLF as the default newline convention. As part of
+this work, the new command was added to several test files and the testing
+scripts were modified. The pcre2grep tests can now also be run when there is no
+LF in the default newline convention.
+
+51. The RunTest script has been modified so that, when JIT is used and valgrind
+is specified, a valgrind suppressions file is set up to ignore "Invalid read of
+size 16" errors because these are false positives when the hardware supports
+the SSE2 instruction set.
+
+52. It is now possible to have comment lines amid the subject strings in
+pcre2test (and perltest.sh) input.
+
+53. Implemented PCRE2_USE_OFFSET_LIMIT and pcre2_set_offset_limit().
+
+54. Add the null_context modifier to pcre2test so that calling pcre2_compile()
+and the matching functions with NULL contexts can be tested.
+
+55. Implemented PCRE2_SUBSTITUTE_EXTENDED.
+
+56. In a character class such as [\W\p{Any}] where both a negative-type escape
+("not a word character") and a property escape were present, the property
+escape was being ignored.
+
+57. Fixed integer overflow for patterns whose minimum matching length is very,
+very large.
+
+58. Implemented --never-backslash-C.
+
+59. Change 55 above introduced a bug by which certain patterns provoked the
+erroneous error "\ at end of pattern".
+
+60. The special sequences [[:<:]] and [[:>:]] gave rise to incorrect compiling
+errors or other strange effects if compiled in UCP mode. Found with libFuzzer
+and AddressSanitizer.
+
+61. Whitespace at the end of a pcre2test pattern line caused a spurious error
+message if there were only single-character modifiers. It should be ignored.
+
+62. The use of PCRE2_NO_AUTO_CAPTURE could cause incorrect compilation results
+or segmentation errors for some patterns. Found with libFuzzer and
+AddressSanitizer.
+
+63. Very long names in (*MARK) or (*THEN) etc. items could provoke a buffer
+overflow.
+
+64. Improve error message for overly-complicated patterns.
+
+65. Implemented an optional replication feature for patterns in pcre2test, to
+make it easier to test long repetitive patterns. The tests for 63 above are
+converted to use the new feature.
+
+66. In the POSIX wrapper, if regerror() was given too small a buffer, it could
+misbehave.
+
+67. In pcre2_substitute() in UTF mode, the UTF validity check on the
+replacement string was happening before the length setting when the replacement
+string was zero-terminated.
+
+68. In pcre2_substitute() in UTF mode, PCRE2_NO_UTF_CHECK can be set for the
+second and subsequent calls to pcre2_match().
+
+69. There was no check for integer overflow for a replacement group number in
+pcre2_substitute(). An added check for a number greater than the largest group
+number in the pattern means this is not now needed.
+
+70. The PCRE2-specific VERSION condition didn't work correctly if only one
+digit was given after the decimal point, or if more than two digits were given.
+It now works with one or two digits, and gives a compile time error if more are
+given.
+
+71. In pcre2_substitute() there was the possibility of reading one code unit
+beyond the end of the replacement string.
+
+72. The code for checking a subject's UTF-32 validity for a pattern with a
+lookbehind involved an out-of-bounds pointer, which could potentially cause
+trouble in some environments.
+
+73. The maximum lookbehind length was incorrectly calculated for patterns such
+as /(?<=(a)(?-1))x/ which have a recursion within a backreference.
+
+74. Give an error if a lookbehind assertion is longer than 65535 code units.
+
+75. Give an error in pcre2_substitute() if a match ends before it starts (as a
+result of the use of \K).
+
+76. Check the length of subpattern names and the names in (*MARK:xx) etc.
+dynamically to avoid the possibility of integer overflow.
+
+77. Implement pcre2_set_max_pattern_length() so that programs can restrict the
+size of patterns that they are prepared to handle.
+
+78. (*NO_AUTO_POSSESS) was not working.
+
+79. Adding group information caching improves the speed of compiling when
+checking whether a group has a fixed length and/or could match an empty string,
+especially when recursion or subroutine calls are involved. However, this
+cannot be used when (?| is present in the pattern because the same number may
+be used for groups of different sizes. To catch runaway patterns in this
+situation, counts have been introduced to the functions that scan for empty
+branches or compute fixed lengths.
+
+80. Allow for the possibility of the size of the nest_save structure not being
+a factor of the size of the compiling workspace (it currently is).
+
+81. Check for integer overflow in minimum length calculation and cap it at
+65535.
+
+82. Small optimizations in code for finding the minimum matching length.
+
+83. Lock out configuring for EBCDIC with non-8-bit libraries.
+
+84. Test for error code <= 0 in regerror().
+
+85. Check for too many replacements (more than INT_MAX) in pcre2_substitute().
+
+86. Avoid the possibility of computing with an out-of-bounds pointer (though
+not dereferencing it) while handling lookbehind assertions.
+
+87. Failure to get memory for the match data in regcomp() is now given as a
+regcomp() error instead of waiting for regexec() to pick it up.
+
+88. In pcre2_substitute(), ensure that CRLF is not split when it is a valid
+newline sequence.
+
+89. Paranoid check in regcomp() for bad error code from pcre2_compile().
+
+90. Run test 8 (internal offsets and code sizes) for link sizes 3 and 4 as well
+as for link size 2.
+
+91. Document that JIT has a limit on pattern size, and give more information
+about JIT compile failures in pcre2test.
+
+92. Implement PCRE2_INFO_HASBACKSLASHC.
+
+93. Re-arrange valgrind support code in pcre2test to avoid spurious reports
+with JIT (possibly caused by SSE2?).
+
+94. Support offset_limit in JIT.
+
+95. A sequence such as [[:punct:]b] that is, a POSIX character class followed
+by a single ASCII character in a class item, was incorrectly compiled in UCP
+mode. The POSIX class got lost, but only if the single character followed it.
+
+96. [:punct:] in UCP mode was matching some characters in the range 128-255
+that should not have been matched.
+
+97. If [:^ascii:] or [:^xdigit:] are present in a non-negated class, all
+characters with code points greater than 255 are in the class. When a Unicode
+property was also in the class (if PCRE2_UCP is set, escapes such as \w are
+turned into Unicode properties), wide characters were not correctly handled,
+and could fail to match.
+
+98. In pcre2test, make the "startoffset" modifier a synonym of "offset",
+because it sets the "startoffset" parameter for pcre2_match().
+
+99. If PCRE2_AUTO_CALLOUT was set on a pattern that had a (?# comment between
+an item and its qualifier (for example, A(?#comment)?B) pcre2_compile()
+misbehaved. This bug was found by the LLVM fuzzer.
+
+100. The error for an invalid UTF pattern string always gave the code unit
+offset as zero instead of where the invalidity was found.
+
+101. Further to 97 above, negated classes such as [^[:^ascii:]\d] were also not
+working correctly in UCP mode.
+
+102. Similar to 99 above, if an isolated \E was present between an item and its
+qualifier when PCRE2_AUTO_CALLOUT was set, pcre2_compile() misbehaved. This bug
+was found by the LLVM fuzzer.
+
+103. The POSIX wrapper function regexec() crashed if the option REG_STARTEND
+was set when the pmatch argument was NULL. It now returns REG_INVARG.
+
+104. Allow for up to 32-bit numbers in the ordin() function in pcre2grep.
+
+105. An empty \Q\E sequence between an item and its qualifier caused
+pcre2_compile() to misbehave when auto callouts were enabled. This bug
+was found by the LLVM fuzzer.
+
+106. If both PCRE2_ALT_VERBNAMES and PCRE2_EXTENDED were set, and a (*MARK) or
+other verb "name" ended with whitespace immediately before the closing
+parenthesis, pcre2_compile() misbehaved. Example: /(*:abc )/, but only when
+both those options were set.
+
+107. In a number of places pcre2_compile() was not handling NULL characters
+correctly, and pcre2test with the "bincode" modifier was not always correctly
+displaying fields containing NULLS:
+
+ (a) Within /x extended #-comments
+ (b) Within the "name" part of (*MARK) and other *verbs
+ (c) Within the text argument of a callout
+
+108. If a pattern that was compiled with PCRE2_EXTENDED started with white
+space or a #-type comment that was followed by (?-x), which turns off
+PCRE2_EXTENDED, and there was no subsequent (?x) to turn it on again,
+pcre2_compile() assumed that (?-x) applied to the whole pattern and
+consequently mis-compiled it. This bug was found by the LLVM fuzzer. The fix
+for this bug means that a setting of any of the (?imsxU) options at the start
+of a pattern is no longer transferred to the options that are returned by
+PCRE2_INFO_ALLOPTIONS. In fact, this was an anachronism that should have
+changed when the effects of those options were all moved to compile time.
+
+109. An escaped closing parenthesis in the "name" part of a (*verb) when
+PCRE2_ALT_VERBNAMES was set caused pcre2_compile() to malfunction. This bug
+was found by the LLVM fuzzer.
+
+110. Implemented PCRE2_SUBSTITUTE_UNSET_EMPTY, and updated pcre2test to make it
+possible to test it.
+
+111. "Harden" pcre2test against ridiculously large values in modifiers and
+command line arguments.
+
+112. Implemented PCRE2_SUBSTITUTE_UNKNOWN_UNSET and PCRE2_SUBSTITUTE_OVERFLOW_
+LENGTH.
+
+113. Fix printing of *MARK names that contain binary zeroes in pcre2test.
+
+
+Version 10.20 30-June-2015
+--------------------------
+
+1. Callouts with string arguments have been added.
+
+2. Assertion code generator in JIT has been optimized.
+
+3. The invalid pattern (?(?C) has a missing assertion condition at the end. The
+pcre2_compile() function read past the end of the input before diagnosing an
+error. This bug was discovered by the LLVM fuzzer.
+
+4. Implemented pcre2_callout_enumerate().
+
+5. Fix JIT compilation of conditional blocks whose assertion is converted to
+(*FAIL). E.g: /(?(?!))/.
+
+6. The pattern /(?(?!)^)/ caused references to random memory. This bug was
+discovered by the LLVM fuzzer.
+
+7. The assertion (?!) is optimized to (*FAIL). This was not handled correctly
+when this assertion was used as a condition, for example (?(?!)a|b). In
+pcre2_match() it worked by luck; in pcre2_dfa_match() it gave an incorrect
+error about an unsupported item.
+
+8. For some types of pattern, for example /Z*(|d*){216}/, the auto-
+possessification code could take exponential time to complete. A recursion
+depth limit of 1000 has been imposed to limit the resources used by this
+optimization. This infelicity was discovered by the LLVM fuzzer.
+
+9. A pattern such as /(*UTF)[\S\V\H]/, which contains a negated special class
+such as \S in non-UCP mode, explicit wide characters (> 255) can be ignored
+because \S ensures they are all in the class. The code for doing this was
+interacting badly with the code for computing the amount of space needed to
+compile the pattern, leading to a buffer overflow. This bug was discovered by
+the LLVM fuzzer.
+
+10. A pattern such as /((?2)+)((?1))/ which has mutual recursion nested inside
+other kinds of group caused stack overflow at compile time. This bug was
+discovered by the LLVM fuzzer.
+
+11. A pattern such as /(?1)(?#?'){8}(a)/ which had a parenthesized comment
+between a subroutine call and its quantifier was incorrectly compiled, leading
+to buffer overflow or other errors. This bug was discovered by the LLVM fuzzer.
+
+12. The illegal pattern /(?(?<E>.*!.*)?)/ was not being diagnosed as missing an
+assertion after (?(. The code was failing to check the character after (?(?<
+for the ! or = that would indicate a lookbehind assertion. This bug was
+discovered by the LLVM fuzzer.
+
+13. A pattern such as /X((?2)()*+){2}+/ which has a possessive quantifier with
+a fixed maximum following a group that contains a subroutine reference was
+incorrectly compiled and could trigger buffer overflow. This bug was discovered
+by the LLVM fuzzer.
+
+14. Negative relative recursive references such as (?-7) to non-existent
+subpatterns were not being diagnosed and could lead to unpredictable behaviour.
+This bug was discovered by the LLVM fuzzer.
+
+15. The bug fixed in 14 was due to an integer variable that was unsigned when
+it should have been signed. Some other "int" variables, having been checked,
+have either been changed to uint32_t or commented as "must be signed".
+
+16. A mutual recursion within a lookbehind assertion such as (?<=((?2))((?1)))
+caused a stack overflow instead of the diagnosis of a non-fixed length
+lookbehind assertion. This bug was discovered by the LLVM fuzzer.
+
+17. The use of \K in a positive lookbehind assertion in a non-anchored pattern
+(e.g. /(?<=\Ka)/) could make pcre2grep loop.
+
+18. There was a similar problem to 17 in pcre2test for global matches, though
+the code there did catch the loop.
+
+19. If a greedy quantified \X was preceded by \C in UTF mode (e.g. \C\X*),
+and a subsequent item in the pattern caused a non-match, backtracking over the
+repeated \X did not stop, but carried on past the start of the subject, causing
+reference to random memory and/or a segfault. There were also some other cases
+where backtracking after \C could crash. This set of bugs was discovered by the
+LLVM fuzzer.
+
+20. The function for finding the minimum length of a matching string could take
+a very long time if mutual recursion was present many times in a pattern, for
+example, /((?2){73}(?2))((?1))/. A better mutual recursion detection method has
+been implemented. This infelicity was discovered by the LLVM fuzzer.
+
+21. Implemented PCRE2_NEVER_BACKSLASH_C.
+
+22. The feature for string replication in pcre2test could read from freed
+memory if the replication required a buffer to be extended, and it was not
+working properly in 16-bit and 32-bit modes. This issue was discovered by a
+fuzzer: see http://lcamtuf.coredump.cx/afl/.
+
+23. Added the PCRE2_ALT_CIRCUMFLEX option.
+
+24. Adjust the treatment of \8 and \9 to be the same as the current Perl
+behaviour.
+
+25. Static linking against the PCRE2 library using the pkg-config module was
+failing on missing pthread symbols.
+
+26. If a group that contained a recursive back reference also contained a
+forward reference subroutine call followed by a non-forward-reference
+subroutine call, for example /.((?2)(?R)\1)()/, pcre2_compile() failed to
+compile correct code, leading to undefined behaviour or an internally detected
+error. This bug was discovered by the LLVM fuzzer.
+
+27. Quantification of certain items (e.g. atomic back references) could cause
+incorrect code to be compiled when recursive forward references were involved.
+For example, in this pattern: /(?1)()((((((\1++))\x85)+)|))/. This bug was
+discovered by the LLVM fuzzer.
+
+28. A repeated conditional group whose condition was a reference by name caused
+a buffer overflow if there was more than one group with the given name. This
+bug was discovered by the LLVM fuzzer.
+
+29. A recursive back reference by name within a group that had the same name as
+another group caused a buffer overflow. For example: /(?J)(?'d'(?'d'\g{d}))/.
+This bug was discovered by the LLVM fuzzer.
+
+30. A forward reference by name to a group whose number is the same as the
+current group, for example in this pattern: /(?|(\k'Pm')|(?'Pm'))/, caused a
+buffer overflow at compile time. This bug was discovered by the LLVM fuzzer.
+
+31. Fix -fsanitize=undefined warnings for left shifts of 1 by 31 (it treats 1
+as an int; fixed by writing it as 1u).
+
+32. Fix pcre2grep compile when -std=c99 is used with gcc, though it still gives
+a warning for "fileno" unless -std=gnu99 us used.
+
+33. A lookbehind assertion within a set of mutually recursive subpatterns could
+provoke a buffer overflow. This bug was discovered by the LLVM fuzzer.
+
+34. Give an error for an empty subpattern name such as (?'').
+
+35. Make pcre2test give an error if a pattern that follows #forbud_utf contains
+\P, \p, or \X.
+
+36. The way named subpatterns are handled has been refactored. There is now a
+pre-pass over the regex which does nothing other than identify named
+subpatterns and count the total captures. This means that information about
+named patterns is known before the rest of the compile. In particular, it means
+that forward references can be checked as they are encountered. Previously, the
+code for handling forward references was contorted and led to several errors in
+computing the memory requirements for some patterns, leading to buffer
+overflows.
+
+37. There was no check for integer overflow in subroutine calls such as (?123).
+
+38. The table entry for \l in EBCDIC environments was incorrect, leading to its
+being treated as a literal 'l' instead of causing an error.
+
+39. If a non-capturing group containing a conditional group that could match
+an empty string was repeated, it was not identified as matching an empty string
+itself. For example: /^(?:(?(1)x|)+)+$()/.
+
+40. In an EBCDIC environment, pcretest was mishandling the escape sequences
+\a and \e in test subject lines.
+
+41. In an EBCDIC environment, \a in a pattern was converted to the ASCII
+instead of the EBCDIC value.
+
+42. The handling of \c in an EBCDIC environment has been revised so that it is
+now compatible with the specification in Perl's perlebcdic page.
+
+43. Single character repetition in JIT has been improved. 20-30% speedup
+was achieved on certain patterns.
+
+44. The EBCDIC character 0x41 is a non-breaking space, equivalent to 0xa0 in
+ASCII/Unicode. This has now been added to the list of characters that are
+recognized as white space in EBCDIC.
+
+45. When PCRE2 was compiled without Unicode support, the use of \p and \P gave
+an error (correctly) when used outside a class, but did not give an error
+within a class.
+
+46. \h within a class was incorrectly compiled in EBCDIC environments.
+
+47. JIT should return with error when the compiled pattern requires
+more stack space than the maximum.
+
+48. Fixed a memory leak in pcre2grep when a locale is set.
+
+
+Version 10.10 06-March-2015
+---------------------------
+
+1. When a pattern is compiled, it remembers the highest back reference so that
+when matching, if the ovector is too small, extra memory can be obtained to
+use instead. A conditional subpattern whose condition is a check on a capture
+having happened, such as, for example in the pattern /^(?:(a)|b)(?(1)A|B)/, is
+another kind of back reference, but it was not setting the highest
+backreference number. This mattered only if pcre2_match() was called with an
+ovector that was too small to hold the capture, and there was no other kind of
+back reference (a situation which is probably quite rare). The effect of the
+bug was that the condition was always treated as FALSE when the capture could
+not be consulted, leading to a incorrect behaviour by pcre2_match(). This bug
+has been fixed.
+
+2. Functions for serialization and deserialization of sets of compiled patterns
+have been added.
+
+3. The value that is returned by PCRE2_INFO_SIZE has been corrected to remove
+excess code units at the end of the data block that may occasionally occur if
+the code for calculating the size over-estimates. This change stops the
+serialization code copying uninitialized data, to which valgrind objects. The
+documentation of PCRE2_INFO_SIZE was incorrect in stating that the size did not
+include the general overhead. This has been corrected.
+
+4. All code units in every slot in the table of group names are now set, again
+in order to avoid accessing uninitialized data when serializing.
+
+5. The (*NO_JIT) feature is implemented.
+
+6. If a bug that caused pcre2_compile() to use more memory than allocated was
+triggered when using valgrind, the code in (3) above passed a stupidly large
+value to valgrind. This caused a crash instead of an "internal error" return.
+
+7. A reference to a duplicated named group (either a back reference or a test
+for being set in a conditional) that occurred in a part of the pattern where
+PCRE2_DUPNAMES was not set caused the amount of memory needed for the pattern
+to be incorrectly calculated, leading to overwriting.
+
+8. A mutually recursive set of back references such as (\2)(\1) caused a
+segfault at compile time (while trying to find the minimum matching length).
+The infinite loop is now broken (with the minimum length unset, that is, zero).
+
+9. If an assertion that was used as a condition was quantified with a minimum
+of zero, matching went wrong. In particular, if the whole group had unlimited
+repetition and could match an empty string, a segfault was likely. The pattern
+(?(?=0)?)+ is an example that caused this. Perl allows assertions to be
+quantified, but not if they are being used as conditions, so the above pattern
+is faulted by Perl. PCRE2 has now been changed so that it also rejects such
+patterns.
+
+10. The error message for an invalid quantifier has been changed from "nothing
+to repeat" to "quantifier does not follow a repeatable item".
+
+11. If a bad UTF string is compiled with NO_UTF_CHECK, it may succeed, but
+scanning the compiled pattern in subsequent auto-possessification can get out
+of step and lead to an unknown opcode. Previously this could have caused an
+infinite loop. Now it generates an "internal error" error. This is a tidyup,
+not a bug fix; passing bad UTF with NO_UTF_CHECK is documented as having an
+undefined outcome.
+
+12. A UTF pattern containing a "not" match of a non-ASCII character and a
+subroutine reference could loop at compile time. Example: /[^\xff]((?1))/.
+
+13. The locale test (RunTest 3) has been upgraded. It now checks that a locale
+that is found in the output of "locale -a" can actually be set by pcre2test
+before it is accepted. Previously, in an environment where a locale was listed
+but would not set (an example does exist), the test would "pass" without
+actually doing anything. Also the fr_CA locale has been added to the list of
+locales that can be used.
+
+14. Fixed a bug in pcre2_substitute(). If a replacement string ended in a
+capturing group number without parentheses, the last character was incorrectly
+literally included at the end of the replacement string.
+
+15. A possessive capturing group such as (a)*+ with a minimum repeat of zero
+failed to allow the zero-repeat case if pcre2_match() was called with an
+ovector too small to capture the group.
+
+16. Improved error message in pcre2test when setting the stack size (-S) fails.
+
+17. Fixed two bugs in CMakeLists.txt: (1) Some lines had got lost in the
+transfer from PCRE1, meaning that CMake configuration failed if "build tests"
+was selected. (2) The file src/pcre2_serialize.c had not been added to the list
+of PCRE2 sources, which caused a failure to build pcre2test.
+
+18. Fixed typo in pcre2_serialize.c (DECL instead of DEFN) that causes problems
+only on Windows.
+
+19. Use binary input when reading back saved serialized patterns in pcre2test.
+
+20. Added RunTest.bat for running the tests under Windows.
+
+21. "make distclean" was not removing config.h, a file that may be created for
+use with CMake.
+
+22. A pattern such as "((?2){0,1999}())?", which has a group containing a
+forward reference repeated a large (but limited) number of times within a
+repeated outer group that has a zero minimum quantifier, caused incorrect code
+to be compiled, leading to the error "internal error: previously-checked
+referenced subpattern not found" when an incorrect memory address was read.
+This bug was reported as "heap overflow", discovered by Kai Lu of Fortinet's
+FortiGuard Labs. (Added 24-March-2015: CVE-2015-2325 was given to this.)
+
+23. A pattern such as "((?+1)(\1))/" containing a forward reference subroutine
+call within a group that also contained a recursive back reference caused
+incorrect code to be compiled. This bug was reported as "heap overflow",
+discovered by Kai Lu of Fortinet's FortiGuard Labs. (Added 24-March-2015:
+CVE-2015-2326 was given to this.)
+
+24. Computing the size of the JIT read-only data in advance has been a source
+of various issues, and new ones are still appear unfortunately. To fix
+existing and future issues, size computation is eliminated from the code,
+and replaced by on-demand memory allocation.
+
+25. A pattern such as /(?i)[A-`]/, where characters in the other case are
+adjacent to the end of the range, and the range contained characters with more
+than one other case, caused incorrect behaviour when compiled in UTF mode. In
+that example, the range a-j was left out of the class.
+
+
+Version 10.00 05-January-2015
+-----------------------------
+
+Version 10.00 is the first release of PCRE2, a revised API for the PCRE
+library. Changes prior to 10.00 are logged in the ChangeLog file for the old
+API, up to item 20 for release 8.36.
+
+The code of the library was heavily revised as part of the new API
+implementation. Details of each and every modification were not individually
+logged. In addition to the API changes, the following changes were made. They
+are either new functionality, or bug fixes and other noticeable changes of
+behaviour that were implemented after the code had been forked.
+
+1. Including Unicode support at build time is now enabled by default, but it
+can optionally be disabled. It is not enabled by default at run time (no
+change).
+
+2. The test program, now called pcre2test, was re-specified and almost
+completely re-written. Its input is not compatible with input for pcretest.
+
+3. Patterns may start with (*NOTEMPTY) or (*NOTEMPTY_ATSTART) to set the
+PCRE2_NOTEMPTY or PCRE2_NOTEMPTY_ATSTART options for every subject line that is
+matched by that pattern.
+
+4. For the benefit of those who use PCRE2 via some other application, that is,
+not writing the function calls themselves, it is possible to check the PCRE2
+version by matching a pattern such as /(?(VERSION>=10)yes|no)/ against a
+string such as "yesno".
+
+5. There are case-equivalent Unicode characters whose encodings use different
+numbers of code units in UTF-8. U+023A and U+2C65 are one example. (It is
+theoretically possible for this to happen in UTF-16 too.) If a backreference to
+a group containing one of these characters was greedily repeated, and during
+the match a backtrack occurred, the subject might be backtracked by the wrong
+number of code units. For example, if /^(\x{23a})\1*(.)/ is matched caselessly
+(and in UTF-8 mode) against "\x{23a}\x{2c65}\x{2c65}\x{2c65}", group 2 should
+capture the final character, which is the three bytes E2, B1, and A5 in UTF-8.
+Incorrect backtracking meant that group 2 captured only the last two bytes.
+This bug has been fixed; the new code is slower, but it is used only when the
+strings matched by the repetition are not all the same length.
+
+6. A pattern such as /()a/ was not setting the "first character must be 'a'"
+information. This applied to any pattern with a group that matched no
+characters, for example: /(?:(?=.)|(?<!x))a/.
+
+7. When an (*ACCEPT) is triggered inside capturing parentheses, it arranges for
+those parentheses to be closed with whatever has been captured so far. However,
+it was failing to mark any other groups between the highest capture so far and
+the currrent group as "unset". Thus, the ovector for those groups contained
+whatever was previously there. An example is the pattern /(x)|((*ACCEPT))/ when
+matched against "abcd".
+
+8. The pcre2_substitute() function has been implemented.
+
+9. If an assertion used as a condition was quantified with a minimum of zero
+(an odd thing to do, but it happened), SIGSEGV or other misbehaviour could
+occur.
+
+10. The PCRE2_NO_DOTSTAR_ANCHOR option has been implemented.

+Technical Notes about PCRE2
+---------------------------
+
+These are very rough technical notes that record potentially useful information
+about PCRE2 internals. PCRE2 is a library based on the original PCRE library,
+but with a revised (and incompatible) API. To avoid confusion, the original
+library is referred to as PCRE1 below. For information about testing PCRE2, see
+the pcre2test documentation and the comment at the head of the RunTest file.
+
+PCRE1 releases were up to 8.3x when PCRE2 was developed. The 8.xx series will
+continue for bugfixes if necessary. PCRE2 releases started at 10.00 to avoid
+confusion with PCRE1.
+
+
+Historical note 1
+-----------------
+
+Many years ago I implemented some regular expression functions to an algorithm
+suggested by Martin Richards. These were not Unix-like in form, and were quite
+restricted in what they could do by comparison with Perl. The interesting part
+about the algorithm was that the amount of space required to hold the compiled
+form of an expression was known in advance. The code to apply an expression did
+not operate by backtracking, as the original Henry Spencer code and current
+PCRE2 and Perl code does, but instead checked all possibilities simultaneously
+by keeping a list of current states and checking all of them as it advanced
+through the subject string. In the terminology of Jeffrey Friedl's book, it was
+a "DFA algorithm", though it was not a traditional Finite State Machine (FSM).
+When the pattern was all used up, all remaining states were possible matches,
+and the one matching the longest subset of the subject string was chosen. This
+did not necessarily maximize the individual wild portions of the pattern, as is
+expected in Unix and Perl-style regular expressions.
+
+
+Historical note 2
+-----------------
+
+By contrast, the code originally written by Henry Spencer (which was
+subsequently heavily modified for Perl) compiles the expression twice: once in
+a dummy mode in order to find out how much store will be needed, and then for
+real. (The Perl version probably doesn't do this any more; I'm talking about
+the original library.) The execution function operates by backtracking and
+maximizing (or, optionally, minimizing, in Perl) the amount of the subject that
+matches individual wild portions of the pattern. This is an "NFA algorithm" in
+Friedl's terminology.
+
+
+OK, here's the real stuff
+-------------------------
+
+For the set of functions that formed the original PCRE1 library (which are
+unrelated to those mentioned above), I tried at first to invent an algorithm
+that used an amount of store bounded by a multiple of the number of characters
+in the pattern, to save on compiling time. However, because of the greater
+complexity in Perl regular expressions, I couldn't do this. In any case, a
+first pass through the pattern is helpful for other reasons.
+
+
+Support for 16-bit and 32-bit data strings
+-------------------------------------------
+
+The library can be compiled in any combination of 8-bit, 16-bit or 32-bit
+modes, creating up to three different libraries. In the description that
+follows, the word "short" is used for a 16-bit data quantity, and the phrase
+"code unit" is used for a quantity that is a byte in 8-bit mode, a short in
+16-bit mode and a 32-bit word in 32-bit mode. The names of PCRE2 functions are
+given in generic form, without the _8, _16, or _32 suffix.
+
+
+Computing the memory requirement: how it was
+--------------------------------------------
+
+Up to and including release 6.7, PCRE1 worked by running a very degenerate
+first pass to calculate a maximum memory requirement, and then a second pass to
+do the real compile - which might use a bit less than the predicted amount of
+memory. The idea was that this would turn out faster than the Henry Spencer
+code because the first pass is degenerate and the second pass can just store
+stuff straight into memory, which it knows is big enough.
+
+
+Computing the memory requirement: how it is
+-------------------------------------------
+
+By the time I was working on a potential 6.8 release, the degenerate first pass
+had become very complicated and hard to maintain. Indeed one of the early
+things I did for 6.8 was to fix Yet Another Bug in the memory computation. Then
+I had a flash of inspiration as to how I could run the real compile function in
+a "fake" mode that enables it to compute how much memory it would need, while
+actually only ever using a few hundred bytes of working memory, and without too
+many tests of the mode that might slow it down. So I refactored the compiling
+functions to work this way. This got rid of about 600 lines of source. It
+should make future maintenance and development easier. As this was such a major
+change, I never released 6.8, instead upping the number to 7.0 (other quite
+major changes were also present in the 7.0 release).
+
+A side effect of this work was that the previous limit of 200 on the nesting
+depth of parentheses was removed. However, there was a downside: compiling ran
+more slowly than before (30% or more, depending on the pattern) because it now
+did a full analysis of the pattern. My hope was that this would not be a big
+issue, and in the event, nobody has commented on it.
+
+At release 8.34, a limit on the nesting depth of parentheses was re-introduced
+(default 250, settable at build time) so as to put a limit on the amount of
+system stack used by the compile function, which uses recursive function calls
+for nested parenthesized groups. This is a safety feature for environments with
+small stacks where the patterns are provided by users.
+
+History repeated itself for release 10.20. A number of bugs relating to named
+subpatterns had been discovered by fuzzers. Most of these were related to the
+handling of forward references when it was not known if the named pattern was
+unique. (References to non-unique names use a different opcode and more
+memory.) The use of duplicate group numbers (the (?| facility) also caused
+issues.
+
+To get around these problems I adopted a new approach by adding a third pass,
+really a "pre-pass", over the pattern, which does nothing other than identify
+all the named subpatterns and their corresponding group numbers. This means
+that the actual compile (both pre-pass and real compile) have full knowledge of
+group names and numbers throughout. Several dozen lines of messy code were
+eliminated, though the new pre-pass is not short (skipping over [] classes is
+complicated).
+
+
+Traditional matching function
+-----------------------------
+
+The "traditional", and original, matching function is called pcre2_match(), and
+it implements an NFA algorithm, similar to the original Henry Spencer algorithm
+and the way that Perl works. This is not surprising, since it is intended to be
+as compatible with Perl as possible. This is the function most users of PCRE2
+will use most of the time. If PCRE2 is compiled with just-in-time (JIT)
+support, and studying a compiled pattern with JIT is successful, the JIT code
+is run instead of the normal pcre2_match() code, but the result is the same.
+
+
+Supplementary matching function
+-------------------------------
+
+There is also a supplementary matching function called pcre2_dfa_match(). This
+implements a DFA matching algorithm that searches simultaneously for all
+possible matches that start at one point in the subject string. (Going back to
+my roots: see Historical Note 1 above.) This function intreprets the same
+compiled pattern data as pcre2_match(); however, not all the facilities are
+available, and those that are do not always work in quite the same way. See the
+user documentation for details.
+
+The algorithm that is used for pcre2_dfa_match() is not a traditional FSM,
+because it may have a number of states active at one time. More work would be
+needed at compile time to produce a traditional FSM where only one state is
+ever active at once. I believe some other regex matchers work this way. JIT
+support is not available for this kind of matching.
+
+
+Changeable options
+------------------
+
+The /i, /m, or /s options (PCRE2_CASELESS, PCRE2_MULTILINE, PCRE2_DOTALL, and
+some others) may change in the middle of patterns. Their processing is handled
+entirely at compile time by generating different opcodes for the different
+settings. The runtime functions do not need to keep track of an options state.
+
+
+Format of compiled patterns
+---------------------------
+
+The compiled form of a pattern is a vector of unsigned code units (bytes in
+8-bit mode, shorts in 16-bit mode, 32-bit words in 32-bit mode), containing
+items of variable length. The first code unit in an item contains an opcode,
+and the length of the item is either implicit in the opcode or contained in the
+data that follows it.
+
+In many cases listed below, LINK_SIZE data values are specified for offsets
+within the compiled pattern. LINK_SIZE always specifies a number of bytes. The
+default value for LINK_SIZE is 2, except for the 32-bit library, where it can
+only be 4. The 8-bit library can be compiled to used 3-byte or 4-byte values,
+and the 16-bit library can be compiled to use 4-byte values, though this
+impairs performance. Specifing a LINK_SIZE larger than 2 for these libraries is
+necessary only when patterns whose compiled length is greater than 64K code
+units are going to be processed. When a LINK_SIZE value uses more than one code
+unit, the most significant unit is first.
+
+In this description, we assume the "normal" compilation options. Data values
+that are counts (e.g. quantifiers) are always two bytes long in 8-bit mode
+(most significant byte first), or one code unit in 16-bit and 32-bit modes.
+
+
+Opcodes with no following data
+------------------------------
+
+These items are all just one unit long
+
+ OP_END end of pattern
+ OP_ANY match any one character other than newline
+ OP_ALLANY match any one character, including newline
+ OP_ANYBYTE match any single code unit, even in UTF-8/16 mode
+ OP_SOD match start of data: \A
+ OP_SOM, start of match (subject + offset): \G
+ OP_SET_SOM, set start of match (\K)
+ OP_CIRC ^ (start of data)
+ OP_CIRCM ^ multiline mode (start of data or after newline)
+ OP_NOT_WORD_BOUNDARY \W
+ OP_WORD_BOUNDARY \w
+ OP_NOT_DIGIT \D
+ OP_DIGIT \d
+ OP_NOT_HSPACE \H
+ OP_HSPACE \h
+ OP_NOT_WHITESPACE \S
+ OP_WHITESPACE \s
+ OP_NOT_VSPACE \V
+ OP_VSPACE \v
+ OP_NOT_WORDCHAR \W
+ OP_WORDCHAR \w
+ OP_EODN match end of data or newline at end: \Z
+ OP_EOD match end of data: \z
+ OP_DOLL $ (end of data, or before final newline)
+ OP_DOLLM $ multiline mode (end of data or before newline)
+ OP_EXTUNI match an extended Unicode grapheme cluster
+ OP_ANYNL match any Unicode newline sequence
+
+ OP_ASSERT_ACCEPT )
+ OP_ACCEPT ) These are Perl 5.10's "backtracking control
+ OP_COMMIT ) verbs". If OP_ACCEPT is inside capturing
+ OP_FAIL ) parentheses, it may be preceded by one or more
+ OP_PRUNE ) OP_CLOSE, each followed by a count that
+ OP_SKIP ) indicates which parentheses must be closed.
+ OP_THEN )
+
+OP_ASSERT_ACCEPT is used when (*ACCEPT) is encountered within an assertion.
+This ends the assertion, not the entire pattern match. The assertion (?!) is
+always optimized to OP_FAIL.
+
+
+Backtracking control verbs with optional data
+---------------------------------------------
+
+(*THEN) without an argument generates the opcode OP_THEN and no following data.
+OP_MARK is followed by the mark name, preceded by a length in one code unit,
+and followed by a binary zero. For (*PRUNE), (*SKIP), and (*THEN) with
+arguments, the opcodes OP_PRUNE_ARG, OP_SKIP_ARG, and OP_THEN_ARG are used,
+with the name following in the same format as OP_MARK.
+
+
+Matching literal characters
+---------------------------
+
+The OP_CHAR opcode is followed by a single character that is to be matched
+casefully. For caseless matching, OP_CHARI is used. In UTF-8 or UTF-16 modes,
+the character may be more than one code unit long. In UTF-32 mode, characters
+are always exactly one code unit long.
+
+If there is only one character in a character class, OP_CHAR or OP_CHARI is
+used for a positive class, and OP_NOT or OP_NOTI for a negative one (that is,
+for something like [^a]).
+
+
+Repeating single characters
+---------------------------
+
+The common repeats (*, +, ?), when applied to a single character, use the
+following opcodes, which come in caseful and caseless versions:
+
+ Caseful Caseless
+ OP_STAR OP_STARI
+ OP_MINSTAR OP_MINSTARI
+ OP_POSSTAR OP_POSSTARI
+ OP_PLUS OP_PLUSI
+ OP_MINPLUS OP_MINPLUSI
+ OP_POSPLUS OP_POSPLUSI
+ OP_QUERY OP_QUERYI
+ OP_MINQUERY OP_MINQUERYI
+ OP_POSQUERY OP_POSQUERYI
+
+Each opcode is followed by the character that is to be repeated. In ASCII or
+UTF-32 modes, these are two-code-unit items; in UTF-8 or UTF-16 modes, the
+length is variable. Those with "MIN" in their names are the minimizing
+versions. Those with "POS" in their names are possessive versions. Other kinds
+of repeat make use of these opcodes:
+
+ Caseful Caseless
+ OP_UPTO OP_UPTOI
+ OP_MINUPTO OP_MINUPTOI
+ OP_POSUPTO OP_POSUPTOI
+ OP_EXACT OP_EXACTI
+
+Each of these is followed by a count and then the repeated character. The count
+is two bytes long in 8-bit mode (most significant byte first), or one code unit
+in 16-bit and 32-bit modes.
+
+OP_UPTO matches from 0 to the given number. A repeat with a non-zero minimum
+and a fixed maximum is coded as an OP_EXACT followed by an OP_UPTO (or
+OP_MINUPTO or OPT_POSUPTO).
+
+Another set of matching repeating opcodes (called OP_NOTSTAR, OP_NOTSTARI,
+etc.) are used for repeated, negated, single-character classes such as [^a]*.
+The normal single-character opcodes (OP_STAR, etc.) are used for repeated
+positive single-character classes.
+
+
+Repeating character types
+-------------------------
+
+Repeats of things like \d are done exactly as for single characters, except
+that instead of a character, the opcode for the type (e.g. OP_DIGIT) is stored
+in the next code unit. The opcodes are:
+
+ OP_TYPESTAR
+ OP_TYPEMINSTAR
+ OP_TYPEPOSSTAR
+ OP_TYPEPLUS
+ OP_TYPEMINPLUS
+ OP_TYPEPOSPLUS
+ OP_TYPEQUERY
+ OP_TYPEMINQUERY
+ OP_TYPEPOSQUERY
+ OP_TYPEUPTO
+ OP_TYPEMINUPTO
+ OP_TYPEPOSUPTO
+ OP_TYPEEXACT
+
+
+Match by Unicode property
+-------------------------
+
+OP_PROP and OP_NOTPROP are used for positive and negative matches of a
+character by testing its Unicode property (the \p and \P escape sequences).
+Each is followed by two code units that encode the desired property as a type
+and a value. The types are a set of #defines of the form PT_xxx, and the values
+are enumerations of the form ucp_xx, defined in the pcre2_ucp.h source file.
+The value is relevant only for PT_GC (General Category), PT_PC (Particular
+Category), and PT_SC (Script).
+
+Repeats of these items use the OP_TYPESTAR etc. set of opcodes, followed by
+three code units: OP_PROP or OP_NOTPROP, and then the desired property type and
+value.
+
+
+Character classes
+-----------------
+
+If there is only one character in a class, OP_CHAR or OP_CHARI is used for a
+positive class, and OP_NOT or OP_NOTI for a negative one (that is, for
+something like [^a]).
+
+A set of repeating opcodes (called OP_NOTSTAR etc.) are used for repeated,
+negated, single-character classes. The normal single-character opcodes
+(OP_STAR, etc.) are used for repeated positive single-character classes.
+
+When there is more than one character in a class, and all the code points are
+less than 256, OP_CLASS is used for a positive class, and OP_NCLASS for a
+negative one. In either case, the opcode is followed by a 32-byte (16-short,
+8-word) bit map containing a 1 bit for every character that is acceptable. The
+bits are counted from the least significant end of each unit. In caseless mode,
+bits for both cases are set.
+
+The reason for having both OP_CLASS and OP_NCLASS is so that, in UTF-8 and
+16-bit and 32-bit modes, subject characters with values greater than 255 can be
+handled correctly. For OP_CLASS they do not match, whereas for OP_NCLASS they
+do.
+
+For classes containing characters with values greater than 255 or that contain
+\p or \P, OP_XCLASS is used. It optionally uses a bit map if any acceptable
+code points are less than 256, followed by a list of pairs (for a range) and/or
+single characters and/or properties. In caseless mode, both cases are
+explicitly listed.
+
+OP_XCLASS is followed by a LINK_SIZE value containing the total length of the
+opcode and its data. This is followed by a code unit containing flag bits:
+XCL_NOT indicates that this is a negative class, and XCL_MAP indicates that a
+bit map is present. There follows the bit map, if XCL_MAP is set, and then a
+sequence of items coded as follows:
+
+ XCL_END marks the end of the list
+ XCL_SINGLE one character follows
+ XCL_RANGE two characters follow
+ XCL_PROP a Unicode property (type, value) follows
+ XCL_NOTPROP a Unicode property (type, value) follows
+
+If a range starts with a code point less than 256 and ends with one greater
+than 255, it is split into two ranges, with characters less than 256 being
+indicated in the bit map, and the rest with XCL_RANGE.
+
+When XCL_NOT is set, the bit map, if present, contains bits for characters that
+are allowed (exactly as for OP_NCLASS), but the list of items that follow it
+specifies characters and properties that are not allowed.
+
+
+Back references
+---------------
+
+OP_REF (caseful) or OP_REFI (caseless) is followed by a count containing the
+reference number when the reference is to a unique capturing group (either by
+number or by name). When named groups are used, there may be more than one
+group with the same name. In this case, a reference to such a group by name
+generates OP_DNREF or OP_DNREFI. These are followed by two counts: the index
+(not the byte offset) in the group name table of the first entry for the
+required name, followed by the number of groups with the same name. The
+matching code can then search for the first one that is set.
+
+
+Repeating character classes and back references
+-----------------------------------------------
+
+Single-character classes are handled specially (see above). This section
+applies to other classes and also to back references. In both cases, the repeat
+information follows the base item. The matching code looks at the following
+opcode to see if it is one of these:
+
+ OP_CRSTAR
+ OP_CRMINSTAR
+ OP_CRPOSSTAR
+ OP_CRPLUS
+ OP_CRMINPLUS
+ OP_CRPOSPLUS
+ OP_CRQUERY
+ OP_CRMINQUERY
+ OP_CRPOSQUERY
+ OP_CRRANGE
+ OP_CRMINRANGE
+ OP_CRPOSRANGE
+
+All but the last three are single-code-unit items, with no data. The others are
+followed by the minimum and maximum repeat counts.
+
+
+Brackets and alternation
+------------------------
+
+A pair of non-capturing round brackets is wrapped round each expression at
+compile time, so alternation always happens in the context of brackets.
+
+[Note for North Americans: "bracket" to some English speakers, including
+myself, can be round, square, curly, or pointy. Hence this usage rather than
+"parentheses".]
+
+Non-capturing brackets use the opcode OP_BRA, capturing brackets use OP_CBRA. A
+bracket opcode is followed by a LINK_SIZE value which gives the offset to the
+next alternative OP_ALT or, if there aren't any branches, to the matching
+OP_KET opcode. Each OP_ALT is followed by a LINK_SIZE value giving the offset
+to the next one, or to the OP_KET opcode. For capturing brackets, the bracket
+number is a count that immediately follows the offset.
+
+OP_KET is used for subpatterns that do not repeat indefinitely, and OP_KETRMIN
+and OP_KETRMAX are used for indefinite repetitions, minimally or maximally
+respectively (see below for possessive repetitions). All three are followed by
+a LINK_SIZE value giving (as a positive number) the offset back to the matching
+bracket opcode.
+
+If a subpattern is quantified such that it is permitted to match zero times, it
+is preceded by one of OP_BRAZERO, OP_BRAMINZERO, or OP_SKIPZERO. These are
+single-unit opcodes that tell the matcher that skipping the following
+subpattern entirely is a valid match. In the case of the first two, not
+skipping the pattern is also valid (greedy and non-greedy). The third is used
+when a pattern has the quantifier {0,0}. It cannot be entirely discarded,
+because it may be called as a subroutine from elsewhere in the pattern.
+
+A subpattern with an indefinite maximum repetition is replicated in the
+compiled data its minimum number of times (or once with OP_BRAZERO if the
+minimum is zero), with the final copy terminating with OP_KETRMIN or OP_KETRMAX
+as appropriate.
+
+A subpattern with a bounded maximum repetition is replicated in a nested
+fashion up to the maximum number of times, with OP_BRAZERO or OP_BRAMINZERO
+before each replication after the minimum, so that, for example, (abc){2,5} is
+compiled as (abc)(abc)((abc)((abc)(abc)?)?)?, except that each bracketed group
+has the same number.
+
+When a repeated subpattern has an unbounded upper limit, it is checked to see
+whether it could match an empty string. If this is the case, the opcode in the
+final replication is changed to OP_SBRA or OP_SCBRA. This tells the matcher
+that it needs to check for matching an empty string when it hits OP_KETRMIN or
+OP_KETRMAX, and if so, to break the loop.
+
+
+Possessive brackets
+-------------------
+
+When a repeated group (capturing or non-capturing) is marked as possessive by
+the "+" notation, e.g. (abc)++, different opcodes are used. Their names all
+have POS on the end, e.g. OP_BRAPOS instead of OP_BRA and OP_SCBRAPOS instead
+of OP_SCBRA. The end of such a group is marked by OP_KETRPOS. If the minimum
+repetition is zero, the group is preceded by OP_BRAPOSZERO.
+
+
+Once-only (atomic) groups
+-------------------------
+
+These are just like other subpatterns, but they start with the opcode
+OP_ONCE or OP_ONCE_NC. The former is used when there are no capturing brackets
+within the atomic group; the latter when there are. The distinction is needed
+for when there is a backtrack to before the group - any captures within the
+group must be reset, so it is necessary to retain backtracking points inside
+the group, even after it is complete, in order to do this. When there are no
+captures in an atomic group, all the backtracking can be discarded when it is
+complete. This is more efficient, and also uses less stack.
+
+The check for matching an empty string in an unbounded repeat is handled
+entirely at runtime, so there are just these two opcodes for atomic groups.
+
+
+Assertions
+----------
+
+Forward assertions are also just like other subpatterns, but starting with one
+of the opcodes OP_ASSERT or OP_ASSERT_NOT. Backward assertions use the opcodes
+OP_ASSERTBACK and OP_ASSERTBACK_NOT, and the first opcode inside the assertion
+is OP_REVERSE, followed by a count of the number of characters to move back the
+pointer in the subject string. In ASCII or UTF-32 mode, the count is also the
+number of code units, but in UTF-8/16 mode each character may occupy more than
+one code unit. A separate count is present in each alternative of a lookbehind
+assertion, allowing them to have different (but fixed) lengths.
+
+
+Conditional subpatterns
+-----------------------
+
+These are like other subpatterns, but they start with the opcode OP_COND, or
+OP_SCOND for one that might match an empty string in an unbounded repeat.
+
+If the condition is a back reference, this is stored at the start of the
+subpattern using the opcode OP_CREF followed by a count containing the
+reference number, provided that the reference is to a unique capturing group.
+If the reference was by name and there is more than one group with that name,
+OP_DNCREF is used instead. It is followed by two counts: the index in the group
+names table, and the number of groups with the same name. The allows the
+matcher to check if any group with the given name is set.
+
+If the condition is "in recursion" (coded as "(?(R)"), or "in recursion of
+group x" (coded as "(?(Rx)"), the group number is stored at the start of the
+subpattern using the opcode OP_RREF (with a value of RREF_ANY (0xffff) for "the
+whole pattern") or OP_DNRREF (with data as for OP_DNCREF).
+
+For a DEFINE condition, OP_FALSE is used (with no associated data). During
+compilation, however, a DEFINE condition is coded as OP_DEFINE so that, when
+the conditional group is complete, there can be a check to ensure that it
+contains only one top-level branch. Once this has happened, the opcode is
+changed to OP_FALSE, so the matcher never sees OP_DEFINE.
+
+There is a special PCRE2-specific condition of the form (VERSION[>]=x.y), which
+tests the PCRE2 version number. This compiles into one of the opcodes OP_TRUE
+or OP_FALSE.
+
+If a condition is not a back reference, recursion test, DEFINE, or VERSION, it
+must start with an assertion, whose opcode normally immediately follows OP_COND
+or OP_SCOND. However, if automatic callouts are enabled, a callout is inserted
+immediately before the assertion. It is also possible to insert a manual
+callout at this point. Only assertion conditions may have callouts preceding
+the condition.
+
+A condition that is the negative assertion (?!) is optimized to OP_FAIL in all
+parts of the pattern, so this is another opcode that may appear as a condition.
+It is treated the same as OP_FALSE.
+
+
+Recursion
+---------
+
+Recursion either matches the current pattern, or some subexpression. The opcode
+OP_RECURSE is followed by a LINK_SIZE value that is the offset to the starting
+bracket from the start of the whole pattern. OP_RECURSE is also used for
+"subroutine" calls, even though they are not strictly a recursion. Repeated
+recursions are automatically wrapped inside OP_ONCE brackets, because otherwise
+some patterns broke them. A non-repeated recursion is not wrapped in OP_ONCE
+brackets, but it is nevertheless still treated as an atomic group.
+
+
+Callout
+-------
+
+A callout can nowadays have either a numerical argument or a string argument.
+These use OP_CALLOUT or OP_CALLOUT_STR, respectively. In each case these are
+followed by two LINK_SIZE values giving the offset in the pattern string to the
+start of the following item, and another count giving the length of this item.
+These values make it possible for pcre2test to output useful tracing
+information using callouts.
+
+In the case of a numeric callout, after these two values there is a single code
+unit containing the callout number, in the range 0-255, with 255 being used for
+callouts that are automatically inserted as a result of the PCRE2_AUTO_CALLOUT
+option. Thus, this opcode item is of fixed length:
+
+ [OP_CALLOUT] [PATTERN_OFFSET] [PATTERN_LENGTH] [NUMBER]
+
+For callouts with string arguments, OP_CALLOUT_STR has three more data items:
+a LINK_SIZE value giving the complete length of the entire opcode item, a
+LINK_SIZE item containing the offset within the pattern string to the start of
+the string argument, and the string itself, preceded by its starting delimiter
+and followed by a binary zero. When a callout function is called, a pointer to
+the actual string is passed, but the delimiter can be accessed as string[-1] if
+the application needs it. In the 8-bit library, the callout in /X(?C'abc')Y/ is
+compiled as the following bytes (decimal numbers represent binary values):
+
+ [OP_CALLOUT] [0] [10] [0] [1] [0] [14] [0] [5] ['] [a] [b] [c] [0]
+ -------- ------- -------- -------
+ | | | |
+ ------- LINK_SIZE items ------
+
+Opcode table checking
+---------------------
+
+The last opcode that is defined in pcre2_internal.h is OP_TABLE_LENGTH. This is
+not a real opcode, but is used to check that tables indexed by opcode are the
+correct length, in order to catch updating errors.

+Installation Instructions
+*************************
+
+Copyright (C) 1994-1996, 1999-2002, 2004-2013 Free Software Foundation,
+Inc.
+
+ Copying and distribution of this file, with or without modification,

+without warranty of any kind.
+
+Basic Installation
+==================
+
+ Briefly, the shell command `./configure && make && make install'
+should configure, build, and install this package. The following
+more-detailed instructions are generic; see the `README' file for
+instructions specific to this package. Some packages provide this
+`INSTALL' file but do not implement all of the features documented
+below. The lack of an optional feature in a given package is not
+necessarily a bug. More recommendations for GNU packages can be found
+in *note Makefile Conventions: (standards)Makefile Conventions.
+
+ The `configure' shell script attempts to guess correct values for
+various system-dependent variables used during compilation. It uses
+those values to create a `Makefile' in each directory of the package.
+It may also create one or more `.h' files containing system-dependent
+definitions. Finally, it creates a shell script `config.status' that
+you can run in the future to recreate the current configuration, and a
+file `config.log' containing compiler output (useful mainly for
+debugging `configure').
+
+ It can also use an optional file (typically called `config.cache'
+and enabled with `--cache-file=config.cache' or simply `-C') that saves
+the results of its tests to speed up reconfiguring. Caching is
+disabled by default to prevent problems with accidental use of stale
+cache files.
+
+ If you need to do unusual things to compile the package, please try
+to figure out how `configure' could check whether to do them, and mail
+diffs or instructions to the address given in the `README' so they can
+be considered for the next release. If you are using the cache, and at
+some point `config.cache' contains results you don't want to keep, you
+may remove or edit it.
+
+ The file `configure.ac' (or `configure.in') is used to create
+`configure' by a program called `autoconf'. You need `configure.ac' if
+you want to change it or regenerate `configure' using a newer version
+of `autoconf'.
+
+ The simplest way to compile this package is:
+
+ 1. `cd' to the directory containing the package's source code and type
+ `./configure' to configure the package for your system.
+
+ Running `configure' might take a while. While running, it prints
+ some messages telling which features it is checking for.
+
+ 2. Type `make' to compile the package.
+
+ 3. Optionally, type `make check' to run any self-tests that come with
+ the package, generally using the just-built uninstalled binaries.
+
+ 4. Type `make install' to install the programs and any data files and
+ documentation. When installing into a prefix owned by root, it is
+ recommended that the package be configured and built as a regular
+ user, and only the `make install' phase executed with root
+ privileges.
+
+ 5. Optionally, type `make installcheck' to repeat any self-tests, but
+ this time using the binaries in their final installed location.
+ This target does not install anything. Running this target as a
+ regular user, particularly if the prior `make install' required
+ root privileges, verifies that the installation completed
+ correctly.
+
+ 6. You can remove the program binaries and object files from the
+ source code directory by typing `make clean'. To also remove the
+ files that `configure' created (so you can compile the package for
+ a different kind of computer), type `make distclean'. There is
+ also a `make maintainer-clean' target, but that is intended mainly
+ for the package's developers. If you use it, you may have to get
+ all sorts of other programs in order to regenerate files that came
+ with the distribution.
+
+ 7. Often, you can also type `make uninstall' to remove the installed
+ files again. In practice, not all packages have tested that
+ uninstallation works correctly, even though it is required by the
+ GNU Coding Standards.
+
+ 8. Some packages, particularly those that use Automake, provide `make
+ distcheck', which can by used by developers to test that all other
+ targets like `make install' and `make uninstall' work correctly.
+ This target is generally not run by end users.
+
+Compilers and Options
+=====================
+
+ Some systems require unusual options for compilation or linking that
+the `configure' script does not know about. Run `./configure --help'
+for details on some of the pertinent environment variables.
+
+ You can give `configure' initial values for configuration parameters
+by setting variables in the command line or in the environment. Here
+is an example:
+
+ ./configure CC=c99 CFLAGS=-g LIBS=-lposix
+
+ *Note Defining Variables::, for more details.
+
+Compiling For Multiple Architectures
+====================================
+
+ You can compile the package for more than one kind of computer at the
+same time, by placing the object files for each architecture in their
+own directory. To do this, you can use GNU `make'. `cd' to the
+directory where you want the object files and executables to go and run
+the `configure' script. `configure' automatically checks for the
+source code in the directory that `configure' is in and in `..'. This
+is known as a "VPATH" build.
+
+ With a non-GNU `make', it is safer to compile the package for one
+architecture at a time in the source code directory. After you have
+installed the package for one architecture, use `make distclean' before
+reconfiguring for another architecture.
+
+ On MacOS X 10.5 and later systems, you can create libraries and
+executables that work on multiple system types--known as "fat" or
+"universal" binaries--by specifying multiple `-arch' options to the
+compiler but only a single `-arch' option to the preprocessor. Like
+this:
+
+ ./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
+ CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
+ CPP="gcc -E" CXXCPP="g++ -E"
+
+ This is not guaranteed to produce working output in all cases, you
+may have to build one architecture at a time and combine the results
+using the `lipo' tool if you have problems.
+
+Installation Names
+==================
+
+ By default, `make install' installs the package's commands under
+`/usr/local/bin', include files under `/usr/local/include', etc. You
+can specify an installation prefix other than `/usr/local' by giving
+`configure' the option `--prefix=PREFIX', where PREFIX must be an
+absolute file name.
+
+ You can specify separate installation prefixes for
+architecture-specific files and architecture-independent files. If you
+pass the option `--exec-prefix=PREFIX' to `configure', the package uses
+PREFIX as the prefix for installing programs and libraries.
+Documentation and other data files still use the regular prefix.
+
+ In addition, if you use an unusual directory layout you can give
+options like `--bindir=DIR' to specify different values for particular
+kinds of files. Run `configure --help' for a list of the directories
+you can set and what kinds of files go in them. In general, the
+default for these options is expressed in terms of `${prefix}', so that
+specifying just `--prefix' will affect all of the other directory
+specifications that were not explicitly provided.
+
+ The most portable way to affect installation locations is to pass the
+correct locations to `configure'; however, many packages provide one or
+both of the following shortcuts of passing variable assignments to the
+`make install' command line to change installation locations without
+having to reconfigure or recompile.
+
+ The first method involves providing an override variable for each
+affected directory. For example, `make install
+prefix=/alternate/directory' will choose an alternate location for all
+directory configuration variables that were expressed in terms of
+`${prefix}'. Any directories that were specified during `configure',
+but not in terms of `${prefix}', must each be overridden at install
+time for the entire installation to be relocated. The approach of
+makefile variable overrides for each directory variable is required by
+the GNU Coding Standards, and ideally causes no recompilation.
+However, some platforms have known limitations with the semantics of
+shared libraries that end up requiring recompilation when using this
+method, particularly noticeable in packages that use GNU Libtool.
+
+ The second method involves providing the `DESTDIR' variable. For
+example, `make install DESTDIR=/alternate/directory' will prepend
+`/alternate/directory' before all installation names. The approach of
+`DESTDIR' overrides is not required by the GNU Coding Standards, and
+does not work on platforms that have drive letters. On the other hand,
+it does better at avoiding recompilation issues, and works well even
+when some directory options were not specified in terms of `${prefix}'
+at `configure' time.
+
+Optional Features
+=================
+
+ If the package supports it, you can cause programs to be installed
+with an extra prefix or suffix on their names by giving `configure' the
+option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
+
+ Some packages pay attention to `--enable-FEATURE' options to
+`configure', where FEATURE indicates an optional part of the package.
+They may also pay attention to `--with-PACKAGE' options, where PACKAGE
+is something like `gnu-as' or `x' (for the X Window System). The
+`README' should mention any `--enable-' and `--with-' options that the
+package recognizes.
+
+ For packages that use the X Window System, `configure' can usually
+find the X include and library files automatically, but if it doesn't,
+you can use the `configure' options `--x-includes=DIR' and
+`--x-libraries=DIR' to specify their locations.
+
+ Some packages offer the ability to configure how verbose the
+execution of `make' will be. For these packages, running `./configure
+--enable-silent-rules' sets the default to minimal output, which can be
+overridden with `make V=1'; while running `./configure
+--disable-silent-rules' sets the default to verbose, which can be
+overridden with `make V=0'.
+
+Particular systems
+==================
+
+ On HP-UX, the default C compiler is not ANSI C compatible. If GNU
+CC is not installed, it is recommended to use the following options in
+order to use an ANSI C compiler:
+
+ ./configure CC="cc -Ae -D_XOPEN_SOURCE=500"
+
+and if that doesn't work, install pre-built binaries of GCC for HP-UX.
+
+ HP-UX `make' updates targets which have the same time stamps as
+their prerequisites, which makes it generally unusable when shipped
+generated files such as `configure' are involved. Use GNU `make'
+instead.
+
+ On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot
+parse its `<wchar.h>' header file. The option `-nodtk' can be used as
+a workaround. If GNU CC is not installed, it is therefore recommended
+to try
+
+ ./configure CC="cc"
+
+and if that doesn't work, try
+
+ ./configure CC="cc -nodtk"
+
+ On Solaris, don't put `/usr/ucb' early in your `PATH'. This
+directory contains several dysfunctional programs; working variants of
+these programs are available in `/usr/bin'. So, if you need `/usr/ucb'
+in your `PATH', put it _after_ `/usr/bin'.
+
+ On Haiku, software installed for all users goes in `/boot/common',
+not `/usr/local'. It is recommended to use the following options:
+
+ ./configure --prefix=/boot/common
+
+Specifying the System Type
+==========================
+
+ There may be some features `configure' cannot figure out
+automatically, but needs to determine by the type of machine the package
+will run on. Usually, assuming the package is built to be run on the
+_same_ architectures, `configure' can figure that out, but if it prints
+a message saying it cannot guess the machine type, give it the
+`--build=TYPE' option. TYPE can either be a short name for the system
+type, such as `sun4', or a canonical name which has the form:
+
+ CPU-COMPANY-SYSTEM
+
+where SYSTEM can have one of these forms:
+
+ OS
+ KERNEL-OS
+
+ See the file `config.sub' for the possible values of each field. If
+`config.sub' isn't included in this package, then this package doesn't
+need to know the machine type.
+
+ If you are _building_ compiler tools for cross-compiling, you should
+use the option `--target=TYPE' to select the type of system they will
+produce code for.
+
+ If you want to _use_ a cross compiler, that generates code for a
+platform different from the build platform, you should specify the
+"host" platform (i.e., that on which the generated programs will
+eventually be run) with `--host=TYPE'.
+
+Sharing Defaults
+================
+
+ If you want to set default values for `configure' scripts to share,
+you can create a site shell script called `config.site' that gives
+default values for variables like `CC', `cache_file', and `prefix'.
+`configure' looks for `PREFIX/share/config.site' if it exists, then
+`PREFIX/etc/config.site' if it exists. Or, you can set the
+`CONFIG_SITE' environment variable to the location of the site script.
+A warning: not all `configure' scripts look for a site script.
+
+Defining Variables
+==================
+
+ Variables not defined in a site shell script can be set in the
+environment passed to `configure'. However, some packages may run
+configure again during the build, and the customized values of these
+variables may be lost. In order to avoid this problem, you should set
+them in the `configure' command line, using `VAR=value'. For example:
+
+ ./configure CC=/usr/local2/bin/gcc
+
+causes the specified `gcc' to be used as the C compiler (unless it is
+overridden in the site shell script).
+
+Unfortunately, this technique does not work for `CONFIG_SHELL' due to
+an Autoconf limitation. Until the limitation is lifted, you can use
+this workaround:
+
+ CONFIG_SHELL=/bin/bash ./configure CONFIG_SHELL=/bin/bash
+
+`configure' Invocation
+======================
+
+ `configure' recognizes the following options to control how it
+operates.
+
+`--help'
+`-h'
+ Print a summary of all of the options to `configure', and exit.
+
+`--help=short'
+`--help=recursive'
+ Print a summary of the options unique to this package's
+ `configure', and exit. The `short' variant lists options used
+ only in the top level, while the `recursive' variant lists options
+ also present in any nested packages.
+
+`--version'
+`-V'
+ Print the version of Autoconf used to generate the `configure'
+ script, and exit.
+
+`--cache-file=FILE'
+ Enable the cache: use and save the results of the tests in FILE,
+ traditionally `config.cache'. FILE defaults to `/dev/null' to
+ disable caching.
+
+`--config-cache'
+`-C'
+ Alias for `--cache-file=config.cache'.
+
+`--quiet'
+`--silent'
+`-q'
+ Do not print messages saying which checks are being made. To
+ suppress all normal output, redirect it to `/dev/null' (any error
+ messages will still be shown).
+
+`--srcdir=DIR'
+ Look for the package's source code in directory DIR. Usually
+ `configure' can determine that directory automatically.
+
+`--prefix=DIR'
+ Use DIR as the installation prefix. *note Installation Names::
+ for more details, including other options available for fine-tuning
+ the installation locations.
+
+`--no-create'
+`-n'
+ Run the configure checks, but stop before creating any output
+ files.
+
+`configure' also accepts some other, not widely useful, options. Run
+`configure --help' for more details.

+PCRE2 LICENCE
+-------------
+
+PCRE2 is a library of functions to support regular expressions whose syntax
+and semantics are as close as possible to those of the Perl 5 language.
+
+Release 10 of PCRE2 is distributed under the terms of the "BSD" licence, as
+specified below. The documentation for PCRE2, supplied in the "doc"
+directory, is distributed under the same terms as the software itself. The data
+in the testdata directory is not copyrighted and is in the public domain.
+
+The basic library functions are written in C and are freestanding. Also
+included in the distribution is a just-in-time compiler that can be used to
+optimize pattern matching. This is an optional feature that can be omitted when
+the library is built.

+News about PCRE2 releases
+-------------------------
+
+Version 10.21 12-January-2016
+-----------------------------
+
+1. Many bugs have been fixed. A large number of them were provoked only by very
+strange pattern input, and were discovered by fuzzers. Some others were
+discovered by code auditing. See ChangeLog for details.
+
+2. The Unicode tables have been updated to Unicode version 8.0.0.
+
+3. For Perl compatibility in EBCDIC environments, ranges such as a-z in a
+class, where both values are literal letters in the same case, omit the
+non-letter EBCDIC code points within the range.
+
+4. There have been a number of enhancements to the pcre2_substitute() function,
+giving more flexibility to replacement facilities. It is now also possible to
+cause the function to return the needed buffer size if the one given is too
+small.
+
+5. The PCRE2_ALT_VERBNAMES option causes the "name" parts of special verbs such
+as (*THEN:name) to be processed for backslashes and to take note of
+PCRE2_EXTENDED.
+
+6. PCRE2_INFO_HASBACKSLASHC makes it possible for a client to find out if a
+pattern uses \C, and --never-backslash-C makes it possible to compile a version
+PCRE2 in which the use of \C is always forbidden.
+
+7. A limit to the length of pattern that can be handled can now be set by
+calling pcre2_set_max_pattern_length().
+
+8. When matching an unanchored pattern, a match can be required to begin within
+a given number of code units after the start of the subject by calling
+pcre2_set_offset_limit().
+
+9. The pcre2test program has been extended to test new facilities, and it can
+now run the tests when LF on its own is not a valid newline sequence.
+
+10. The RunTest script has also been updated to enable more tests to be run.
+
+11. There have been some minor performance enhancements.
+
+
+Version 10.20 30-June-2015
+--------------------------
+
+1. Callouts with string arguments and the pcre2_callout_enumerate() function
+have been implemented.
+
+2. The PCRE2_NEVER_BACKSLASH_C option, which locks out the use of \C, is added.
+
+3. The PCRE2_ALT_CIRCUMFLEX option lets ^ match after a newline at the end of a
+subject in multiline mode.
+
+4. The way named subpatterns are handled has been refactored. The previous
+approach had several bugs.
+
+5. The handling of \c in EBCDIC environments has been changed to conform to the
+perlebcdic document. This is an incompatible change.
+
+6. Bugs have been mended, many of them discovered by fuzzers.
+
+
+Version 10.10 06-March-2015
+---------------------------
+
+1. Serialization and de-serialization functions have been added to the API,
+making it possible to save and restore sets of compiled patterns, though
+restoration must be done in the same environment that was used for compilation.
+
+2. The (*NO_JIT) feature has been added; this makes it possible for a pattern
+creator to specify that JIT is not to be used.
+
+3. A number of bugs have been fixed. In particular, bugs that caused building
+on Windows using CMake to fail have been mended.
+
+
+Version 10.00 05-January-2015
+-----------------------------
+
+Version 10.00 is the first release of PCRE2, a revised API for the PCRE
+library. Changes prior to 10.00 are logged in the ChangeLog file for the old
+API, up to item 20 for release 8.36. New programs are recommended to use the
+new library. Programs that use the original (PCRE1) API will need changing
+before linking with the new library.

+Building PCRE2 without using autotools
+--------------------------------------
+
+This document has been converted from the PCRE1 document. I have removed a
+number of sections about building in various environments, as they applied only
+to PCRE1 and are probably out of date.
+
+This document contains the following sections:
+
+ General
+ Generic instructions for the PCRE2 C library
+ Stack size in Windows environments
+ Linking programs in Windows environments
+ Calling conventions in Windows environments
+ Comments about Win32 builds
+ Building PCRE2 on Windows with CMake
+ Testing with RunTest.bat
+ Building PCRE2 on native z/OS and z/VM
+
+
+GENERAL
+
+The basic PCRE2 library consists entirely of code written in Standard C, and so
+should compile successfully on any system that has a Standard C compiler and
+library.
+
+The PCRE2 distribution includes a "configure" file for use by the
+configure/make (autotools) build system, as found in many Unix-like
+environments. The README file contains information about the options for
+"configure".
+
+There is also support for CMake, which some users prefer, especially in Windows
+environments, though it can also be run in Unix-like environments. See the
+section entitled "Building PCRE2 on Windows with CMake" below.
+
+Versions of src/config.h and src/pcre2.h are distributed in the PCRE2 tarballs
+under the names src/config.h.generic and src/pcre2.h.generic. These are
+provided for those who build PCRE2 without using "configure" or CMake. If you
+use "configure" or CMake, the .generic versions are not used.
+
+
+GENERIC INSTRUCTIONS FOR THE PCRE2 C LIBRARY
+
+The following are generic instructions for building the PCRE2 C library "by
+hand". If you are going to use CMake, this section does not apply to you; you
+can skip ahead to the CMake section.
+
+ (1) Copy or rename the file src/config.h.generic as src/config.h, and edit the
+ macro settings that it contains to whatever is appropriate for your
+ environment. In particular, you can alter the definition of the NEWLINE
+ macro to specify what character(s) you want to be interpreted as line
+ terminators.
+
+ When you compile any of the PCRE2 modules, you must specify
+ -DHAVE_CONFIG_H to your compiler so that src/config.h is included in the
+ sources.
+
+ An alternative approach is not to edit src/config.h, but to use -D on the
+ compiler command line to make any changes that you need to the
+ configuration options. In this case -DHAVE_CONFIG_H must not be set.
+
+ NOTE: There have been occasions when the way in which certain parameters
+ in src/config.h are used has changed between releases. (In the
+ configure/make world, this is handled automatically.) When upgrading to a
+ new release, you are strongly advised to review src/config.h.generic
+ before re-using what you had previously.
+
+ (2) Copy or rename the file src/pcre2.h.generic as src/pcre2.h.
+
+ (3) EITHER:
+ Copy or rename file src/pcre2_chartables.c.dist as
+ src/pcre2_chartables.c.
+
+ OR:
+ Compile src/dftables.c as a stand-alone program (using -DHAVE_CONFIG_H
+ if you have set up src/config.h), and then run it with the single
+ argument "src/pcre2_chartables.c". This generates a set of standard
+ character tables and writes them to that file. The tables are generated
+ using the default C locale for your system. If you want to use a locale
+ that is specified by LC_xxx environment variables, add the -L option to
+ the dftables command. You must use this method if you are building on a
+ system that uses EBCDIC code.
+
+ The tables in src/pcre2_chartables.c are defaults. The caller of PCRE2 can
+ specify alternative tables at run time.
+
+ (4) For an 8-bit library, compile the following source files from the src
+ directory, setting -DPCRE2_CODE_UNIT_WIDTH=8 as a compiler option. Also
+ set -DHAVE_CONFIG_H if you have set up src/config.h with your
+ configuration, or else use other -D settings to change the configuration
+ as required.
+
+ pcre2_auto_possess.c
+ pcre2_chartables.c
+ pcre2_compile.c
+ pcre2_config.c
+ pcre2_context.c
+ pcre2_dfa_match.c
+ pcre2_error.c
+ pcre2_find_bracket.c
+ pcre2_jit_compile.c
+ pcre2_maketables.c
+ pcre2_match.c
+ pcre2_match_data.c
+ pcre2_newline.c
+ pcre2_ord2utf.c
+ pcre2_pattern_info.c
+ pcre2_serialize.c
+ pcre2_string_utils.c
+ pcre2_study.c
+ pcre2_substitute.c
+ pcre2_substring.c
+ pcre2_tables.c
+ pcre2_ucd.c
+ pcre2_valid_utf.c
+ pcre2_xclass.c
+
+ Make sure that you include -I. in the compiler command (or equivalent for
+ an unusual compiler) so that all included PCRE2 header files are first
+ sought in the src directory under the current directory. Otherwise you run
+ the risk of picking up a previously-installed file from somewhere else.
+
+ Note that you must compile pcre2_jit_compile.c, even if you have not
+ defined SUPPORT_JIT in src/config.h, because when JIT support is not
+ configured, dummy functions are compiled. When JIT support IS configured,
+ pcre2_compile.c #includes other files from the sljit subdirectory, where
+ there should be 16 files, all of whose names begin with "sljit". It also
+ #includes src/pcre2_jit_match.c and src/pcre2_jit_misc.c, so you should
+ not compile these yourself.
+
+ (5) Now link all the compiled code into an object library in whichever form
+ your system keeps such libraries. This is the basic PCRE2 C 8-bit library.
+ If your system has static and shared libraries, you may have to do this
+ once for each type.
+
+ (6) If you want to build a 16-bit library or 32-bit library (as well as, or
+ instead of the 8-bit library) just supply 16 or 32 as the value of
+ -DPCRE2_CODE_UNIT_WIDTH when you are compiling.
+
+ (7) If you want to build the POSIX wrapper functions (which apply only to the
+ 8-bit library), ensure that you have the src/pcre2posix.h file and then
+ compile src/pcre2posix.c. Link the result (on its own) as the pcre2posix
+ library.
+
+ (8) The pcre2test program can be linked with any combination of the 8-bit,
+ 16-bit and 32-bit libraries (depending on what you selected in
+ src/config.h). Compile src/pcre2test.c; don't forget -DHAVE_CONFIG_H if
+ necessary, but do NOT define PCRE2_CODE_UNIT_WIDTH. Then link with the
+ appropriate library/ies. If you compiled an 8-bit library, pcre2test also
+ needs the pcre2posix wrapper library.
+
+ (9) Run pcre2test on the testinput files in the testdata directory, and check
+ that the output matches the corresponding testoutput files. There are
+ comments about what each test does in the section entitled "Testing PCRE2"
+ in the README file. If you compiled more than one of the 8-bit, 16-bit and
+ 32-bit libraries, you need to run pcre2test with the -16 option to do
+ 16-bit tests and with the -32 option to do 32-bit tests.
+
+ Some tests are relevant only when certain build-time options are selected.
+ For example, test 4 is for Unicode support, and will not run if you have
+ built PCRE2 without it. See the comments at the start of each testinput
+ file. If you have a suitable Unix-like shell, the RunTest script will run
+ the appropriate tests for you. The command "RunTest list" will output a
+ list of all the tests.
+
+ Note that the supplied files are in Unix format, with just LF characters
+ as line terminators. You may need to edit them to change this if your
+ system uses a different convention.
+
+(10) If you have built PCRE2 with SUPPORT_JIT, the JIT features can be tested
+ by running pcre2test with the -jit option. This is done automatically by
+ the RunTest script. You might also like to build and run the freestanding
+ JIT test program, src/pcre2_jit_test.c.
+
+(11) If you want to use the pcre2grep command, compile and link
+ src/pcre2grep.c; it uses only the basic 8-bit PCRE2 library (it does not
+ need the pcre2posix library).
+
+
+STACK SIZE IN WINDOWS ENVIRONMENTS
+
+The default processor stack size of 1Mb in some Windows environments is too
+small for matching patterns that need much recursion. In particular, test 2 may
+fail because of this. Normally, running out of stack causes a crash, but there
+have been cases where the test program has just died silently. See your linker
+documentation for how to increase stack size if you experience problems. If you
+are using CMake (see "BUILDING PCRE2 ON WINDOWS WITH CMAKE" below) and the gcc
+compiler, you can increase the stack size for pcre2test and pcre2grep by
+setting the CMAKE_EXE_LINKER_FLAGS variable to "-Wl,--stack,8388608" (for
+example). The Linux default of 8Mb is a reasonable choice for the stack, though
+even that can be too small for some pattern/subject combinations.
+
+PCRE2 has a compile configuration option to disable the use of stack for
+recursion so that heap is used instead. However, pattern matching is
+significantly slower when this is done. There is more about stack usage in the
+"pcre2stack" documentation.
+
+
+LINKING PROGRAMS IN WINDOWS ENVIRONMENTS
+
+If you want to statically link a program against a PCRE2 library in the form of
+a non-dll .a file, you must define PCRE2_STATIC before including src/pcre2.h.
+
+
+CALLING CONVENTIONS IN WINDOWS ENVIRONMENTS
+
+It is possible to compile programs to use different calling conventions using
+MSVC. Search the web for "calling conventions" for more information. To make it
+easier to change the calling convention for the exported functions in the
+PCRE2 library, the macro PCRE2_CALL_CONVENTION is present in all the external
+definitions. It can be set externally when compiling (e.g. in CFLAGS). If it is
+not set, it defaults to empty; the default calling convention is then used
+(which is what is wanted most of the time).
+
+
+COMMENTS ABOUT WIN32 BUILDS (see also "BUILDING PCRE2 ON WINDOWS WITH CMAKE")
+
+There are two ways of building PCRE2 using the "configure, make, make install"
+paradigm on Windows systems: using MinGW or using Cygwin. These are not at all
+the same thing; they are completely different from each other. There is also
+support for building using CMake, which some users find a more straightforward
+way of building PCRE2 under Windows.
+
+The MinGW home page (http://www.mingw.org/) says this:
+
+ MinGW: A collection of freely available and freely distributable Windows
+ specific header files and import libraries combined with GNU toolsets that
+ allow one to produce native Windows programs that do not rely on any
+ 3rd-party C runtime DLLs.
+
+The Cygwin home page (http://www.cygwin.com/) says this:
+
+ Cygwin is a Linux-like environment for Windows. It consists of two parts:
+
+ . A DLL (cygwin1.dll) which acts as a Linux API emulation layer providing
+ substantial Linux API functionality
+
+ . A collection of tools which provide Linux look and feel.
+
+On both MinGW and Cygwin, PCRE2 should build correctly using:
+
+ ./configure && make && make install
+
+This should create two libraries called libpcre2-8 and libpcre2-posix. These
+are independent libraries: when you link with libpcre2-posix you must also link
+with libpcre2-8, which contains the basic functions.
+
+Using Cygwin's compiler generates libraries and executables that depend on
+cygwin1.dll. If a library that is generated this way is distributed,
+cygwin1.dll has to be distributed as well. Since cygwin1.dll is under the GPL
+licence, this forces not only PCRE2 to be under the GPL, but also the entire
+application. A distributor who wants to keep their own code proprietary must
+purchase an appropriate Cygwin licence.
+
+MinGW has no such restrictions. The MinGW compiler generates a library or
+executable that can run standalone on Windows without any third party dll or
+licensing issues.
+
+But there is more complication:
+
+If a Cygwin user uses the -mno-cygwin Cygwin gcc flag, what that really does is
+to tell Cygwin's gcc to use the MinGW gcc. Cygwin's gcc is only acting as a
+front end to MinGW's gcc (if you install Cygwin's gcc, you get both Cygwin's
+gcc and MinGW's gcc). So, a user can:
+
+. Build native binaries by using MinGW or by getting Cygwin and using
+ -mno-cygwin.
+
+. Build binaries that depend on cygwin1.dll by using Cygwin with the normal
+ compiler flags.
+
+The test files that are supplied with PCRE2 are in UNIX format, with LF
+characters as line terminators. Unless your PCRE2 library uses a default
+newline option that includes LF as a valid newline, it may be necessary to
+change the line terminators in the test files to get some of the tests to work.
+
+
+BUILDING PCRE2 ON WINDOWS WITH CMAKE
+
+CMake is an alternative configuration facility that can be used instead of
+"configure". CMake creates project files (make files, solution files, etc.)
+tailored to numerous development environments, including Visual Studio,
+Borland, Msys, MinGW, NMake, and Unix. If possible, use short paths with no
+spaces in the names for your CMake installation and your PCRE2 source and build
+directories.
+
+The following instructions were contributed by a PCRE1 user, but they should
+also work for PCRE2. If they are not followed exactly, errors may occur. In the
+event that errors do occur, it is recommended that you delete the CMake cache
+before attempting to repeat the CMake build process. In the CMake GUI, the
+cache can be deleted by selecting "File > Delete Cache".
+
+1. Install the latest CMake version available from http://www.cmake.org/, and
+ ensure that cmake\bin is on your path.
+
+2. Unzip (retaining folder structure) the PCRE2 source tree into a source
+ directory such as C:\pcre2. You should ensure your local date and time
+ is not earlier than the file dates in your source dir if the release is
+ very new.
+
+3. Create a new, empty build directory, preferably a subdirectory of the
+ source dir. For example, C:\pcre2\pcre2-xx\build.
+
+4. Run cmake-gui from the Shell envirornment of your build tool, for example,
+ Msys for Msys/MinGW or Visual Studio Command Prompt for VC/VC++. Do not try
+ to start Cmake from the Windows Start menu, as this can lead to errors.
+
+5. Enter C:\pcre2\pcre2-xx and C:\pcre2\pcre2-xx\build for the source and
+ build directories, respectively.
+
+6. Hit the "Configure" button.
+
+7. Select the particular IDE / build tool that you are using (Visual
+ Studio, MSYS makefiles, MinGW makefiles, etc.)
+
+8. The GUI will then list several configuration options. This is where
+ you can disable Unicode support or select other PCRE2 optional features.
+
+9. Hit "Configure" again. The adjacent "Generate" button should now be
+ active.
+
+10. Hit "Generate".
+
+11. The build directory should now contain a usable build system, be it a
+ solution file for Visual Studio, makefiles for MinGW, etc. Exit from
+ cmake-gui and use the generated build system with your compiler or IDE.
+ E.g., for MinGW you can run "make", or for Visual Studio, open the PCRE2
+ solution, select the desired configuration (Debug, or Release, etc.) and
+ build the ALL_BUILD project.
+
+12. If during configuration with cmake-gui you've elected to build the test
+ programs, you can execute them by building the test project. E.g., for
+ MinGW: "make test"; for Visual Studio build the RUN_TESTS project. The
+ most recent build configuration is targeted by the tests. A summary of
+ test results is presented. Complete test output is subsequently
+ available for review in Testing\Temporary under your build dir.
+
+
+TESTING WITH RUNTEST.BAT
+
+If configured with CMake, building the test project ("make test" or building
+ALL_TESTS in Visual Studio) creates (and runs) pcre2_test.bat (and depending
+on your configuration options, possibly other test programs) in the build
+directory. The pcre2_test.bat script runs RunTest.bat with correct source and
+exe paths.
+
+For manual testing with RunTest.bat, provided the build dir is a subdirectory
+of the source directory: Open command shell window. Chdir to the location
+of your pcre2test.exe and pcre2grep.exe programs. Call RunTest.bat with
+"..\RunTest.Bat" or "..\..\RunTest.bat" as appropriate.
+
+To run only a particular test with RunTest.Bat provide a test number argument.
+
+Otherwise:
+
+1. Copy RunTest.bat into the directory where pcre2test.exe and pcre2grep.exe
+ have been created.
+
+2. Edit RunTest.bat to indentify the full or relative location of
+ the pcre2 source (wherein which the testdata folder resides), e.g.:
+
+ set srcdir=C:\pcre2\pcre2-10.00
+
+3. In a Windows command environment, chdir to the location of your bat and
+ exe programs.
+
+4. Run RunTest.bat. Test outputs will automatically be compared to expected
+ results, and discrepancies will be identified in the console output.
+
+To independently test the just-in-time compiler, run pcre2_jit_test.exe.
+
+
+BUILDING PCRE2 ON NATIVE Z/OS AND Z/VM
+
+z/OS and z/VM are operating systems for mainframe computers, produced by IBM.
+The character code used is EBCDIC, not ASCII or Unicode. In z/OS, UNIX APIs and
+applications can be supported through UNIX System Services, and in such an
+environment PCRE2 can be built in the same way as in other systems. However, in
+native z/OS (without UNIX System Services) and in z/VM, special ports are
+required. For details, please see this web site:
+
+ http://www.zaconsultants.net
+
+The site currently has ports for PCRE1 releases, but PCRE2 should follow in due
+course.
+
+You may also download PCRE1 from WWW.CBTTAPE.ORG, file 882. Everything, source
+and executable, is in EBCDIC and native z/OS file formats and this is the
+recommended download site.

+README file for PCRE2 (Perl-compatible regular expression library)
+------------------------------------------------------------------
+
+PCRE2 is a re-working of the original PCRE library to provide an entirely new
+API. The latest release of PCRE2 is always available in three alternative
+formats from:
+
+ ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/pcre2-xxx.tar.gz
+ ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/pcre2-xxx.tar.bz2
+ ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/pcre2-xxx.zip
+
+There is a mailing list for discussion about the development of PCRE (both the
+original and new APIs) at pcre-dev@exim.org. You can access the archives and
+subscribe or manage your subscription here:

+
+
+The PCRE2 APIs
+--------------
+
+PCRE2 is written in C, and it has its own API. There are three sets of
+functions, one for the 8-bit library, which processes strings of bytes, one for
+the 16-bit library, which processes strings of 16-bit values, and one for the
+32-bit library, which processes strings of 32-bit values. There are no C++
+wrappers.
+
+The distribution does contain a set of C wrapper functions for the 8-bit
+library that are based on the POSIX regular expression API (see the pcre2posix
+man page). These can be found in a library called libpcre2posix. Note that this
+just provides a POSIX calling interface to PCRE2; the regular expressions
+themselves still follow Perl syntax and semantics. The POSIX API is restricted,
+and does not give full access to all of PCRE2's facilities.
+
+The header file for the POSIX-style functions is called pcre2posix.h. The
+official POSIX name is regex.h, but I did not want to risk possible problems
+with existing files of that name by distributing it that way. To use PCRE2 with
+an existing program that uses the POSIX API, pcre2posix.h will have to be
+renamed or pointed at by a link.
+
+If you are using the POSIX interface to PCRE2 and there is already a POSIX
+regex library installed on your system, as well as worrying about the regex.h
+header file (as mentioned above), you must also take care when linking programs
+to ensure that they link with PCRE2's libpcre2posix library. Otherwise they may
+pick up the POSIX functions of the same name from the other library.
+
+One way of avoiding this confusion is to compile PCRE2 with the addition of
+-Dregcomp=PCRE2regcomp (and similarly for the other POSIX functions) to the
+compiler flags (CFLAGS if you are using "configure" -- see below). This has the
+effect of renaming the functions so that the names no longer clash. Of course,
+you have to do the same thing for your applications, or write them using the
+new names.
+
+
+Documentation for PCRE2
+-----------------------
+
+If you install PCRE2 in the normal way on a Unix-like system, you will end up
+with a set of man pages whose names all start with "pcre2". The one that is
+just called "pcre2" lists all the others. In addition to these man pages, the
+PCRE2 documentation is supplied in two other forms:
+
+ 1. There are files called doc/pcre2.txt, doc/pcre2grep.txt, and
+ doc/pcre2test.txt in the source distribution. The first of these is a
+ concatenation of the text forms of all the section 3 man pages except the
+ listing of pcre2demo.c and those that summarize individual functions. The
+ other two are the text forms of the section 1 man pages for the pcre2grep
+ and pcre2test commands. These text forms are provided for ease of scanning
+ with text editors or similar tools. They are installed in
+ <prefix>/share/doc/pcre2, where <prefix> is the installation prefix
+ (defaulting to /usr/local).
+
+ 2. A set of files containing all the documentation in HTML form, hyperlinked
+ in various ways, and rooted in a file called index.html, is distributed in
+ doc/html and installed in <prefix>/share/doc/pcre2/html.
+
+
+Building PCRE2 on non-Unix-like systems
+---------------------------------------
+
+For a non-Unix-like system, please read the comments in the file
+NON-AUTOTOOLS-BUILD, though if your system supports the use of "configure" and
+"make" you may be able to build PCRE2 using autotools in the same way as for
+many Unix-like systems.
+
+PCRE2 can also be configured using CMake, which can be run in various ways
+(command line, GUI, etc). This creates Makefiles, solution files, etc. The file
+NON-AUTOTOOLS-BUILD has information about CMake.
+
+PCRE2 has been compiled on many different operating systems. It should be
+straightforward to build PCRE2 on any system that has a Standard C compiler and
+library, because it uses only Standard C functions.
+
+
+Building PCRE2 without using autotools
+--------------------------------------
+
+The use of autotools (in particular, libtool) is problematic in some
+environments, even some that are Unix or Unix-like. See the NON-AUTOTOOLS-BUILD
+file for ways of building PCRE2 without using autotools.
+
+
+Building PCRE2 using autotools
+------------------------------
+
+The following instructions assume the use of the widely used "configure; make;
+make install" (autotools) process.
+
+To build PCRE2 on system that supports autotools, first run the "configure"
+command from the PCRE2 distribution directory, with your current directory set
+to the directory where you want the files to be created. This command is a
+standard GNU "autoconf" configuration script, for which generic instructions
+are supplied in the file INSTALL.
+
+Most commonly, people build PCRE2 within its own distribution directory, and in
+this case, on many systems, just running "./configure" is sufficient. However,
+the usual methods of changing standard defaults are available. For example:
+
+CFLAGS='-O2 -Wall' ./configure --prefix=/opt/local
+
+This command specifies that the C compiler should be run with the flags '-O2
+-Wall' instead of the default, and that "make install" should install PCRE2
+under /opt/local instead of the default /usr/local.
+
+If you want to build in a different directory, just run "configure" with that
+directory as current. For example, suppose you have unpacked the PCRE2 source
+into /source/pcre2/pcre2-xxx, but you want to build it in
+/build/pcre2/pcre2-xxx:
+
+cd /build/pcre2/pcre2-xxx
+/source/pcre2/pcre2-xxx/configure
+
+PCRE2 is written in C and is normally compiled as a C library. However, it is
+possible to build it as a C++ library, though the provided building apparatus
+does not have any features to support this.
+
+There are some optional features that can be included or omitted from the PCRE2
+library. They are also documented in the pcre2build man page.
+
+. By default, both shared and static libraries are built. You can change this
+ by adding one of these options to the "configure" command:
+
+ --disable-shared
+ --disable-static
+
+ (See also "Shared libraries on Unix-like systems" below.)
+
+. By default, only the 8-bit library is built. If you add --enable-pcre2-16 to
+ the "configure" command, the 16-bit library is also built. If you add
+ --enable-pcre2-32 to the "configure" command, the 32-bit library is also
+ built. If you want only the 16-bit or 32-bit library, use --disable-pcre2-8
+ to disable building the 8-bit library.
+
+. If you want to include support for just-in-time compiling, which can give
+ large performance improvements on certain platforms, add --enable-jit to the
+ "configure" command. This support is available only for certain hardware
+ architectures. If you try to enable it on an unsupported architecture, there
+ will be a compile time error.
+
+. When JIT support is enabled, pcre2grep automatically makes use of it, unless
+ you add --disable-pcre2grep-jit to the "configure" command.
+
+. If you do not want to make use of the support for UTF-8 Unicode character
+ strings in the 8-bit library, UTF-16 Unicode character strings in the 16-bit
+ library, or UTF-32 Unicode character strings in the 32-bit library, you can
+ add --disable-unicode to the "configure" command. This reduces the size of
+ the libraries. It is not possible to configure one library with Unicode
+ support, and another without, in the same configuration.
+
+ When Unicode support is available, the use of a UTF encoding still has to be
+ enabled by setting the PCRE2_UTF option at run time or starting a pattern
+ with (*UTF). When PCRE2 is compiled with Unicode support, its input can only
+ either be ASCII or UTF-8/16/32, even when running on EBCDIC platforms. It is
+ not possible to use both --enable-unicode and --enable-ebcdic at the same
+ time.
+
+ As well as supporting UTF strings, Unicode support includes support for the
+ \P, \p, and \X sequences that recognize Unicode character properties.
+ However, only the basic two-letter properties such as Lu are supported.
+ Escape sequences such as \d and \w in patterns do not by default make use of
+ Unicode properties, but can be made to do so by setting the PCRE2_UCP option
+ or starting a pattern with (*UCP).
+
+. You can build PCRE2 to recognize either CR or LF or the sequence CRLF, or any
+ of the preceding, or any of the Unicode newline sequences, as indicating the
+ end of a line. Whatever you specify at build time is the default; the caller
+ of PCRE2 can change the selection at run time. The default newline indicator
+ is a single LF character (the Unix standard). You can specify the default
+ newline indicator by adding --enable-newline-is-cr, --enable-newline-is-lf,
+ --enable-newline-is-crlf, --enable-newline-is-anycrlf, or
+ --enable-newline-is-any to the "configure" command, respectively.
+
+ If you specify --enable-newline-is-cr or --enable-newline-is-crlf, some of
+ the standard tests will fail, because the lines in the test files end with
+ LF. Even if the files are edited to change the line endings, there are likely
+ to be some failures. With --enable-newline-is-anycrlf or
+ --enable-newline-is-any, many tests should succeed, but there may be some
+ failures.
+
+. By default, the sequence \R in a pattern matches any Unicode line ending
+ sequence. This is independent of the option specifying what PCRE2 considers
+ to be the end of a line (see above). However, the caller of PCRE2 can
+ restrict \R to match only CR, LF, or CRLF. You can make this the default by
+ adding --enable-bsr-anycrlf to the "configure" command (bsr = "backslash R").
+
+. In a pattern, the escape sequence \C matches a single code unit, even in a
+ UTF mode. This can be dangerous because it breaks up multi-code-unit
+ characters. You can build PCRE2 with the use of \C permanently locked out by
+ adding --enable-never-backslash-C (note the upper case C) to the "configure"
+ command. When \C is allowed by the library, individual applications can lock
+ it out by calling pcre2_compile() with the PCRE2_NEVER_BACKSLASH_C option.
+
+. PCRE2 has a counter that limits the depth of nesting of parentheses in a
+ pattern. This limits the amount of system stack that a pattern uses when it
+ is compiled. The default is 250, but you can change it by setting, for
+ example,
+
+ --with-parens-nest-limit=500
+
+. PCRE2 has a counter that can be set to limit the amount of resources it uses
+ when matching a pattern. If the limit is exceeded during a match, the match
+ fails. The default is ten million. You can change the default by setting, for
+ example,
+
+ --with-match-limit=500000
+
+ on the "configure" command. This is just the default; individual calls to
+ pcre2_match() can supply their own value. There is more discussion on the
+ pcre2api man page.
+
+. There is a separate counter that limits the depth of recursive function calls
+ during a matching process. This also has a default of ten million, which is
+ essentially "unlimited". You can change the default by setting, for example,
+
+ --with-match-limit-recursion=500000
+
+ Recursive function calls use up the runtime stack; running out of stack can
+ cause programs to crash in strange ways. There is a discussion about stack
+ sizes in the pcre2stack man page.
+
+. In the 8-bit library, the default maximum compiled pattern size is around
+ 64K. You can increase this by adding --with-link-size=3 to the "configure"
+ command. PCRE2 then uses three bytes instead of two for offsets to different
+ parts of the compiled pattern. In the 16-bit library, --with-link-size=3 is
+ the same as --with-link-size=4, which (in both libraries) uses four-byte
+ offsets. Increasing the internal link size reduces performance in the 8-bit
+ and 16-bit libraries. In the 32-bit library, the link size setting is
+ ignored, as 4-byte offsets are always used.
+
+. You can build PCRE2 so that its internal match() function that is called from
+ pcre2_match() does not call itself recursively. Instead, it uses memory
+ blocks obtained from the heap to save data that would otherwise be saved on
+ the stack. To build PCRE2 like this, use
+
+ --disable-stack-for-recursion
+
+ on the "configure" command. PCRE2 runs more slowly in this mode, but it may
+ be necessary in environments with limited stack sizes. This applies only to
+ the normal execution of the pcre2_match() function; if JIT support is being
+ successfully used, it is not relevant. Equally, it does not apply to
+ pcre2_dfa_match(), which does not use deeply nested recursion. There is a
+ discussion about stack sizes in the pcre2stack man page.
+
+. For speed, PCRE2 uses four tables for manipulating and identifying characters
+ whose code point values are less than 256. By default, it uses a set of
+ tables for ASCII encoding that is part of the distribution. If you specify
+
+ --enable-rebuild-chartables
+
+ a program called dftables is compiled and run in the default C locale when
+ you obey "make". It builds a source file called pcre2_chartables.c. If you do
+ not specify this option, pcre2_chartables.c is created as a copy of
+ pcre2_chartables.c.dist. See "Character tables" below for further
+ information.
+
+. It is possible to compile PCRE2 for use on systems that use EBCDIC as their
+ character code (as opposed to ASCII/Unicode) by specifying
+
+ --enable-ebcdic --disable-unicode
+
+ This automatically implies --enable-rebuild-chartables (see above). However,
+ when PCRE2 is built this way, it always operates in EBCDIC. It cannot support
+ both EBCDIC and UTF-8/16/32. There is a second option, --enable-ebcdic-nl25,
+ which specifies that the code value for the EBCDIC NL character is 0x25
+ instead of the default 0x15.
+
+. If you specify --enable-debug, additional debugging code is included in the
+ build. This option is intended for use by the PCRE2 maintainers.
+
+. In environments where valgrind is installed, if you specify
+
+ --enable-valgrind
+
+ PCRE2 will use valgrind annotations to mark certain memory regions as
+ unaddressable. This allows it to detect invalid memory accesses, and is
+ mostly useful for debugging PCRE2 itself.
+
+. In environments where the gcc compiler is used and lcov version 1.6 or above
+ is installed, if you specify
+
+ --enable-coverage
+
+ the build process implements a code coverage report for the test suite. The
+ report is generated by running "make coverage". If ccache is installed on
+ your system, it must be disabled when building PCRE2 for coverage reporting.
+ You can do this by setting the environment variable CCACHE_DISABLE=1 before
+ running "make" to build PCRE2. There is more information about coverage
+ reporting in the "pcre2build" documentation.
+
+. The pcre2grep program currently supports only 8-bit data files, and so
+ requires the 8-bit PCRE2 library. It is possible to compile pcre2grep to use
+ libz and/or libbz2, in order to read .gz and .bz2 files (respectively), by
+ specifying one or both of
+
+ --enable-pcre2grep-libz
+ --enable-pcre2grep-libbz2
+
+ Of course, the relevant libraries must be installed on your system.
+
+. The default size (in bytes) of the internal buffer used by pcre2grep can be
+ set by, for example:
+
+ --with-pcre2grep-bufsize=51200
+
+ The value must be a plain integer. The default is 20480.
+
+. It is possible to compile pcre2test so that it links with the libreadline
+ or libedit libraries, by specifying, respectively,
+
+ --enable-pcre2test-libreadline or --enable-pcre2test-libedit
+
+ If this is done, when pcre2test's input is from a terminal, it reads it using
+ the readline() function. This provides line-editing and history facilities.
+ Note that libreadline is GPL-licenced, so if you distribute a binary of
+ pcre2test linked in this way, there may be licensing issues. These can be
+ avoided by linking with libedit (which has a BSD licence) instead.
+
+ Enabling libreadline causes the -lreadline option to be added to the
+ pcre2test build. In many operating environments with a sytem-installed
+ readline library this is sufficient. However, in some environments (e.g. if
+ an unmodified distribution version of readline is in use), it may be
+ necessary to specify something like LIBS="-lncurses" as well. This is
+ because, to quote the readline INSTALL, "Readline uses the termcap functions,
+ but does not link with the termcap or curses library itself, allowing
+ applications which link with readline the to choose an appropriate library."
+ If you get error messages about missing functions tgetstr, tgetent, tputs,
+ tgetflag, or tgoto, this is the problem, and linking with the ncurses library
+ should fix it.
+
+The "configure" script builds the following files for the basic C library:
+
+. Makefile the makefile that builds the library
+. src/config.h build-time configuration options for the library
+. src/pcre2.h the public PCRE2 header file
+. pcre2-config script that shows the building settings such as CFLAGS
+ that were set for "configure"
+. libpcre2-8.pc )
+. libpcre2-16.pc ) data for the pkg-config command
+. libpcre2-32.pc )
+. libpcre2-posix.pc )
+. libtool script that builds shared and/or static libraries
+
+Versions of config.h and pcre2.h are distributed in the src directory of PCRE2
+tarballs under the names config.h.generic and pcre2.h.generic. These are
+provided for those who have to build PCRE2 without using "configure" or CMake.
+If you use "configure" or CMake, the .generic versions are not used.
+
+The "configure" script also creates config.status, which is an executable
+script that can be run to recreate the configuration, and config.log, which
+contains compiler output from tests that "configure" runs.
+
+Once "configure" has run, you can run "make". This builds whichever of the
+libraries libpcre2-8, libpcre2-16 and libpcre2-32 are configured, and a test
+program called pcre2test. If you enabled JIT support with --enable-jit, another
+test program called pcre2_jit_test is built as well. If the 8-bit library is
+built, libpcre2-posix and the pcre2grep command are also built. Running
+"make" with the -j option may speed up compilation on multiprocessor systems.
+
+The command "make check" runs all the appropriate tests. Details of the PCRE2
+tests are given below in a separate section of this document. The -j option of
+"make" can also be used when running the tests.
+
+You can use "make install" to install PCRE2 into live directories on your
+system. The following are installed (file names are all relative to the
+<prefix> that is set when "configure" is run):
+
+ Commands (bin):
+ pcre2test
+ pcre2grep (if 8-bit support is enabled)
+ pcre2-config
+
+ Libraries (lib):
+ libpcre2-8 (if 8-bit support is enabled)
+ libpcre2-16 (if 16-bit support is enabled)
+ libpcre2-32 (if 32-bit support is enabled)
+ libpcre2-posix (if 8-bit support is enabled)
+
+ Configuration information (lib/pkgconfig):
+ libpcre2-8.pc
+ libpcre2-16.pc
+ libpcre2-32.pc
+ libpcre2-posix.pc
+
+ Header files (include):
+ pcre2.h
+ pcre2posix.h
+
+ Man pages (share/man/man{1,3}):
+ pcre2grep.1
+ pcre2test.1
+ pcre2-config.1
+ pcre2.3
+ pcre2*.3 (lots more pages, all starting "pcre2")

+ pcre2test.txt the pcre2test man page
+ pcre2grep.txt the pcre2grep man page
+ pcre2-config.txt the pcre2-config man page
+
+If you want to remove PCRE2 from your system, you can run "make uninstall".
+This removes all the files that "make install" installed. However, it does not
+remove any directories, because these are often shared with other programs.
+
+
+Retrieving configuration information
+------------------------------------
+
+Running "make install" installs the command pcre2-config, which can be used to
+recall information about the PCRE2 configuration and installation. For example:
+
+ pcre2-config --version
+
+prints the version number, and
+
+ pcre2-config --libs8
+
+outputs information about where the 8-bit library is installed. This command
+can be included in makefiles for programs that use PCRE2, saving the programmer
+from having to remember too many details. Run pcre2-config with no arguments to
+obtain a list of possible arguments.
+
+The pkg-config command is another system for saving and retrieving information
+about installed libraries. Instead of separate commands for each library, a
+single command is used. For example:
+
+ pkg-config --libs libpcre2-16
+
+The data is held in *.pc files that are installed in a directory called
+<prefix>/lib/pkgconfig.
+
+
+Shared libraries
+----------------
+
+The default distribution builds PCRE2 as shared libraries and static libraries,
+as long as the operating system supports shared libraries. Shared library
+support relies on the "libtool" script which is built as part of the
+"configure" process.
+
+The libtool script is used to compile and link both shared and static
+libraries. They are placed in a subdirectory called .libs when they are newly
+built. The programs pcre2test and pcre2grep are built to use these uninstalled
+libraries (by means of wrapper scripts in the case of shared libraries). When
+you use "make install" to install shared libraries, pcre2grep and pcre2test are
+automatically re-built to use the newly installed shared libraries before being
+installed themselves. However, the versions left in the build directory still
+use the uninstalled libraries.
+
+To build PCRE2 using static libraries only you must use --disable-shared when
+configuring it. For example:
+
+./configure --prefix=/usr/gnu --disable-shared
+
+Then run "make" in the usual way. Similarly, you can use --disable-static to
+build only shared libraries.
+
+
+Cross-compiling using autotools
+-------------------------------
+
+You can specify CC and CFLAGS in the normal way to the "configure" command, in
+order to cross-compile PCRE2 for some other host. However, you should NOT
+specify --enable-rebuild-chartables, because if you do, the dftables.c source
+file is compiled and run on the local host, in order to generate the inbuilt
+character tables (the pcre2_chartables.c file). This will probably not work,
+because dftables.c needs to be compiled with the local compiler, not the cross
+compiler.
+
+When --enable-rebuild-chartables is not specified, pcre2_chartables.c is
+created by making a copy of pcre2_chartables.c.dist, which is a default set of
+tables that assumes ASCII code. Cross-compiling with the default tables should
+not be a problem.
+
+If you need to modify the character tables when cross-compiling, you should
+move pcre2_chartables.c.dist out of the way, then compile dftables.c by hand
+and run it on the local host to make a new version of pcre2_chartables.c.dist.
+Then when you cross-compile PCRE2 this new version of the tables will be used.
+
+
+Making new tarballs
+-------------------
+
+The command "make dist" creates three PCRE2 tarballs, in tar.gz, tar.bz2, and
+zip formats. The command "make distcheck" does the same, but then does a trial
+build of the new distribution to ensure that it works.
+
+If you have modified any of the man page sources in the doc directory, you
+should first run the PrepareRelease script before making a distribution. This
+script creates the .txt and HTML forms of the documentation from the man pages.
+
+
+Testing PCRE2
+------------
+
+To test the basic PCRE2 library on a Unix-like system, run the RunTest script.
+There is another script called RunGrepTest that tests the pcre2grep command.
+When JIT support is enabled, a third test program called pcre2_jit_test is
+built. Both the scripts and all the program tests are run if you obey "make
+check". For other environments, see the instructions in NON-AUTOTOOLS-BUILD.
+
+The RunTest script runs the pcre2test test program (which is documented in its
+own man page) on each of the relevant testinput files in the testdata
+directory, and compares the output with the contents of the corresponding
+testoutput files. RunTest uses a file called testtry to hold the main output
+from pcre2test. Other files whose names begin with "test" are used as working
+files in some tests.
+
+Some tests are relevant only when certain build-time options were selected. For
+example, the tests for UTF-8/16/32 features are run only when Unicode support
+is available. RunTest outputs a comment when it skips a test.
+
+Many (but not all) of the tests that are not skipped are run twice if JIT
+support is available. On the second run, JIT compilation is forced. This
+testing can be suppressed by putting "nojit" on the RunTest command line.
+
+The entire set of tests is run once for each of the 8-bit, 16-bit and 32-bit
+libraries that are enabled. If you want to run just one set of tests, call
+RunTest with either the -8, -16 or -32 option.
+
+If valgrind is installed, you can run the tests under it by putting "valgrind"
+on the RunTest command line. To run pcre2test on just one or more specific test
+files, give their numbers as arguments to RunTest, for example:
+
+ RunTest 2 7 11
+
+You can also specify ranges of tests such as 3-6 or 3- (meaning 3 to the
+end), or a number preceded by ~ to exclude a test. For example:
+
+ Runtest 3-15 ~10
+
+This runs tests 3 to 15, excluding test 10, and just ~13 runs all the tests
+except test 13. Whatever order the arguments are in, the tests are always run
+in numerical order.
+
+You can also call RunTest with the single argument "list" to cause it to output
+a list of tests.
+
+The test sequence starts with "test 0", which is a special test that has no
+input file, and whose output is not checked. This is because it will be
+different on different hardware and with different configurations. The test
+exists in order to exercise some of pcre2test's code that would not otherwise
+be run.
+
+Tests 1 and 2 can always be run, as they expect only plain text strings (not
+UTF) and make no use of Unicode properties. The first test file can be fed
+directly into the perltest.sh script to check that Perl gives the same results.
+The only difference you should see is in the first few lines, where the Perl
+version is given instead of the PCRE2 version. The second set of tests check
+auxiliary functions, error detection, and run-time flags that are specific to
+PCRE2. It also uses the debugging flags to check some of the internals of
+pcre2_compile().
+
+If you build PCRE2 with a locale setting that is not the standard C locale, the
+character tables may be different (see next paragraph). In some cases, this may
+cause failures in the second set of tests. For example, in a locale where the
+isprint() function yields TRUE for characters in the range 128-255, the use of
+[:isascii:] inside a character class defines a different set of characters, and
+this shows up in this test as a difference in the compiled code, which is being
+listed for checking. For example, where the comparison test output contains
+[\x00-\x7f] the test might contain [\x00-\xff], and similarly in some other
+cases. This is not a bug in PCRE2.
+
+Test 3 checks pcre2_maketables(), the facility for building a set of character
+tables for a specific locale and using them instead of the default tables. The
+script uses the "locale" command to check for the availability of the "fr_FR",
+"french", or "fr" locale, and uses the first one that it finds. If the "locale"
+command fails, or if its output doesn't include "fr_FR", "french", or "fr" in
+the list of available locales, the third test cannot be run, and a comment is
+output to say why. If running this test produces an error like this:
+
+ ** Failed to set locale "fr_FR"
+
+it means that the given locale is not available on your system, despite being
+listed by "locale". This does not mean that PCRE2 is broken. There are three
+alternative output files for the third test, because three different versions
+of the French locale have been encountered. The test passes if its output
+matches any one of them.
+
+Tests 4 and 5 check UTF and Unicode property support, test 4 being compatible
+with the perltest.sh script, and test 5 checking PCRE2-specific things.
+
+Tests 6 and 7 check the pcre2_dfa_match() alternative matching function, in
+non-UTF mode and UTF-mode with Unicode property support, respectively.
+
+Test 8 checks some internal offsets and code size features; it is run only when
+the default "link size" of 2 is set (in other cases the sizes change) and when
+Unicode support is enabled.
+
+Tests 9 and 10 are run only in 8-bit mode, and tests 11 and 12 are run only in
+16-bit and 32-bit modes. These are tests that generate different output in
+8-bit mode. Each pair are for general cases and Unicode support, respectively.
+Test 13 checks the handling of non-UTF characters greater than 255 by
+pcre2_dfa_match() in 16-bit and 32-bit modes.
+
+Test 14 contains a number of tests that must not be run with JIT. They check,
+among other non-JIT things, the match-limiting features of the intepretive
+matcher.
+
+Test 15 is run only when JIT support is not available. It checks that an
+attempt to use JIT has the expected behaviour.
+
+Test 16 is run only when JIT support is available. It checks JIT complete and
+partial modes, match-limiting under JIT, and other JIT-specific features.
+
+Tests 17 and 18 are run only in 8-bit mode. They check the POSIX interface to
+the 8-bit library, without and with Unicode support, respectively.
+
+Test 19 checks the serialization functions by writing a set of compiled
+patterns to a file, and then reloading and checking them.
+
+
+Character tables
+----------------
+
+For speed, PCRE2 uses four tables for manipulating and identifying characters
+whose code point values are less than 256. By default, a set of tables that is
+built into the library is used. The pcre2_maketables() function can be called
+by an application to create a new set of tables in the current locale. This are
+passed to PCRE2 by calling pcre2_set_character_tables() to put a pointer into a
+compile context.
+
+The source file called pcre2_chartables.c contains the default set of tables.
+By default, this is created as a copy of pcre2_chartables.c.dist, which
+contains tables for ASCII coding. However, if --enable-rebuild-chartables is
+specified for ./configure, a different version of pcre2_chartables.c is built
+by the program dftables (compiled from dftables.c), which uses the ANSI C
+character handling functions such as isalnum(), isalpha(), isupper(),
+islower(), etc. to build the table sources. This means that the default C
+locale which is set for your system will control the contents of these default
+tables. You can change the default tables by editing pcre2_chartables.c and
+then re-building PCRE2. If you do this, you should take care to ensure that the
+file does not get automatically re-generated. The best way to do this is to
+move pcre2_chartables.c.dist out of the way and replace it with your customized
+tables.
+
+When the dftables program is run as a result of --enable-rebuild-chartables,
+it uses the default C locale that is set on your system. It does not pay
+attention to the LC_xxx environment variables. In other words, it uses the
+system's default locale rather than whatever the compiling user happens to have
+set. If you really do want to build a source set of character tables in a
+locale that is specified by the LC_xxx variables, you can run the dftables
+program by hand with the -L option. For example:
+
+ ./dftables -L pcre2_chartables.c.special
+
+The first two 256-byte tables provide lower casing and case flipping functions,
+respectively. The next table consists of three 32-byte bit maps which identify
+digits, "word" characters, and white space, respectively. These are used when
+building 32-byte bit maps that represent character classes for code points less
+than 256. The final 256-byte table has bits indicating various character types,
+as follows:
+
+ 1 white space character
+ 2 letter
+ 4 decimal digit
+ 8 hexadecimal digit
+ 16 alphanumeric or '_'
+ 128 regular expression metacharacter or binary zero
+
+You should not alter the set of characters that contain the 128 bit, as that
+will cause PCRE2 to malfunction.

+###############################################################################
+# Run the PCRE2 tests using the pcre2test program. The appropriate tests are
+# selected, depending on which build-time options were used.
+#
+# When JIT support is available, all appropriate tests are run with and without
+# JIT, unless "-nojit" is given on the command line. There are also two tests
+# for JIT-specific features, one to be run when JIT support is available
+# (unless "-nojit" is specified), and one when it is not.
+#
+# Whichever of the 8-, 16- and 32-bit libraries exist are tested. It is also
+# possible to select which to test by giving "-8", "-16" or "-32" on the
+# command line.
+#
+# As well as "-nojit", "-8", "-16", and "-32", arguments for this script are
+# individual test numbers, ranges of tests such as 3-6 or 3- (meaning 3 to the
+# end), or a number preceded by ~ to exclude a test. For example, "3-15 ~10"
+# runs tests 3 to 15, excluding test 10, and just "~10" runs all the tests
+# except test 10. Whatever order the arguments are in, the tests are always run
+# in numerical order.
+#
+# Inappropriate tests are automatically skipped (with a comment to say so). For
+# example, if JIT support is not compiled, test 16 is skipped, whereas if JIT
+# support is compiled, test 15 is skipped.
+#
+# Other arguments can be one of the words "-valgrind", "-valgrind-log", or
+# "-sim" followed by an argument to run cross-compiled executables under a
+# simulator, for example:
+#
+# RunTest 3 -sim "qemu-arm -s 8388608"
+#
+# For backwards compatibility, -nojit, -valgrind, -valgrind-log, and -sim may
+# be given without the leading "-" character.
+#
+# When PCRE2 is compiled by clang with -fsanitize arguments, some tests need
+# very much more stack than normal. In environments where the stack can be
+# set at runtime, -bigstack sets a gigantic stack.
+#
+# There are two special cases where only one argument is allowed:
+#
+# If the first and only argument is "ebcdic", the script runs the special
+# EBCDIC test that can be useful for checking certain EBCDIC features, even
+# when run in an ASCII environment. PCRE2 must be built with EBCDIC support for
+# this test to be run.
+#
+# If the script is obeyed as "RunTest list", a list of available tests is
+# output, but none of them are run.

+@rem Philip H also changed test 3 to use "wintest" files.
+@rem
+@rem Updated by Tom Fortmann to support explicit test numbers on the command
+@rem line. Added argument validation and added error reporting.
+@rem
+@rem Sheri Pierce added logic to skip feature dependent tests
+@rem tests 4 5 7 10 12 14 19 and 22 require Unicode support
+@rem 8 requires Unicode and link size 2
+@rem 16 requires absence of jit support
+@rem 17 requires presence of jit support
+@rem Sheri P also added override tests for study and jit testing
+@rem Zoltan Herczeg added libpcre16 support
+@rem Zoltan Herczeg added libpcre32 support
+@rem -------------------------------------------------------------------
+@rem
+@rem The file was converted for PCRE2 by PH, February 2015.
+@rem Updated for new test 14 (moving others up a number), August 2015.
+@rem Tidied and updated for new tests 21, 22, 23 by PH, October 2015.

+# Of course, Automake must honor this variable whenever it calls a

+# therefore $ac_aux_dir as well) can be either absolute or relative,
+# depending on how configure is run. This is pretty annoying, since
+# it makes $ac_aux_dir quite unusable in subdirectories: in the top
+# source directory, any form will work fine, but in subdirectories a

+#
+# $ac_aux_dir/missing
+# fails when called from a subdirectory if $ac_aux_dir is relative
+# $top_srcdir/$ac_aux_dir/missing
+# fails if $ac_aux_dir is absolute,
+# fails when called from a subdirectory in a VPATH build with
+# a relative $ac_aux_dir
+#
+# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
+# are both prefixed by $srcdir. In an in-source build this is usually
+# harmless because $srcdir is '.', but things will broke when you
+# start a VPATH build or use an absolute $srcdir.
+#
+# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
+# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
+# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
+# and then we would define $MISSING as
+# MISSING="\${SHELL} $am_aux_dir/missing"
+# This will work as long as MISSING is not called from configure, because
+# unfortunately $(top_srcdir) has no meaning in configure.
+# However there are other variables, like CC, which are often used in
+# configure, and could therefore not use this "fixed" $ac_aux_dir.

+\`configure' configures PCRE2 10.21 to adapt to many kinds of systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE. See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+ -h, --help display this help and exit
+ --help=short display options specific to this package
+ --help=recursive display the short help of all the included packages
+ -V, --version display version information and exit
+ -q, --quiet, --silent do not print \`checking ...' messages
+ --cache-file=FILE cache test results in FILE [disabled]
+ -C, --config-cache alias for \`--cache-file=config.cache'
+ -n, --no-create do not create output files
+ --srcdir=DIR find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+ --prefix=PREFIX install architecture-independent files in PREFIX
+ [$ac_default_prefix]
+ --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
+ [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.
+
+Fine tuning of the installation directories:
+ --bindir=DIR user executables [EPREFIX/bin]
+ --sbindir=DIR system admin executables [EPREFIX/sbin]
+ --libexecdir=DIR program executables [EPREFIX/libexec]
+ --sysconfdir=DIR read-only single-machine data [PREFIX/etc]

+/* PCRE2 is written in Standard C, but there are a few non-standard things it
+can cope with, allowing it to run on SunOS4 and other "close to standard"
+systems.
+
+In environments that support the GNU autotools, config.h.in is converted into
+config.h by the "configure" script. In environments that use CMake,
+config-cmake.in is converted into config.h. If you are going to build PCRE2 "by
+hand" without using "configure" or CMake, you should copy the distributed
+config.h.generic to config.h, and edit the macro definitions to be the way you
+need them. You must then add -DHAVE_CONFIG_H to all of your compile commands,
+so that config.h is included at the start of every source.
+
+Alternatively, you can avoid editing by using -D on the compiler command line
+to set the macro values. In this case, you do not have to set -DHAVE_CONFIG_H,
+but if you do, default values will be taken from config.h for non-boolean
+macros that are not defined on the command line.
+
+Boolean macros such as HAVE_STDLIB_H and SUPPORT_PCRE2_8 should either be defined
+(conventionally to 1) for TRUE, and not defined at all for FALSE. All such
+macros are listed as a commented #undef in config.h.generic. Macros such as
+MATCH_LIMIT, whose actual value is relevant, have defaults defined, but are
+surrounded by #ifndef/#endif lines so that the value can be overridden by -D.
+
+PCRE2 uses memmove() if HAVE_MEMMOVE is defined; otherwise it uses bcopy() if
+HAVE_BCOPY is defined. If your system has neither bcopy() nor memmove(), make
+sure both macros are undefined; an emulation function will then be used. */])

+Building PCRE2 without using autotools
+--------------------------------------
+
+This document has been converted from the PCRE1 document. I have removed a
+number of sections about building in various environments, as they applied only
+to PCRE1 and are probably out of date.
+
+This document contains the following sections:
+
+ General
+ Generic instructions for the PCRE2 C library
+ Stack size in Windows environments
+ Linking programs in Windows environments
+ Calling conventions in Windows environments
+ Comments about Win32 builds
+ Building PCRE2 on Windows with CMake
+ Testing with RunTest.bat
+ Building PCRE2 on native z/OS and z/VM
+
+
+GENERAL
+
+The basic PCRE2 library consists entirely of code written in Standard C, and so
+should compile successfully on any system that has a Standard C compiler and
+library.
+
+The PCRE2 distribution includes a "configure" file for use by the
+configure/make (autotools) build system, as found in many Unix-like
+environments. The README file contains information about the options for
+"configure".
+
+There is also support for CMake, which some users prefer, especially in Windows
+environments, though it can also be run in Unix-like environments. See the
+section entitled "Building PCRE2 on Windows with CMake" below.
+
+Versions of src/config.h and src/pcre2.h are distributed in the PCRE2 tarballs
+under the names src/config.h.generic and src/pcre2.h.generic. These are
+provided for those who build PCRE2 without using "configure" or CMake. If you
+use "configure" or CMake, the .generic versions are not used.
+
+
+GENERIC INSTRUCTIONS FOR THE PCRE2 C LIBRARY
+
+The following are generic instructions for building the PCRE2 C library "by
+hand". If you are going to use CMake, this section does not apply to you; you
+can skip ahead to the CMake section.
+
+ (1) Copy or rename the file src/config.h.generic as src/config.h, and edit the
+ macro settings that it contains to whatever is appropriate for your
+ environment. In particular, you can alter the definition of the NEWLINE
+ macro to specify what character(s) you want to be interpreted as line
+ terminators.
+
+ When you compile any of the PCRE2 modules, you must specify
+ -DHAVE_CONFIG_H to your compiler so that src/config.h is included in the
+ sources.
+
+ An alternative approach is not to edit src/config.h, but to use -D on the
+ compiler command line to make any changes that you need to the
+ configuration options. In this case -DHAVE_CONFIG_H must not be set.
+
+ NOTE: There have been occasions when the way in which certain parameters
+ in src/config.h are used has changed between releases. (In the
+ configure/make world, this is handled automatically.) When upgrading to a
+ new release, you are strongly advised to review src/config.h.generic
+ before re-using what you had previously.
+
+ (2) Copy or rename the file src/pcre2.h.generic as src/pcre2.h.
+
+ (3) EITHER:
+ Copy or rename file src/pcre2_chartables.c.dist as
+ src/pcre2_chartables.c.
+
+ OR:
+ Compile src/dftables.c as a stand-alone program (using -DHAVE_CONFIG_H
+ if you have set up src/config.h), and then run it with the single
+ argument "src/pcre2_chartables.c". This generates a set of standard
+ character tables and writes them to that file. The tables are generated
+ using the default C locale for your system. If you want to use a locale
+ that is specified by LC_xxx environment variables, add the -L option to
+ the dftables command. You must use this method if you are building on a
+ system that uses EBCDIC code.
+
+ The tables in src/pcre2_chartables.c are defaults. The caller of PCRE2 can
+ specify alternative tables at run time.
+
+ (4) For an 8-bit library, compile the following source files from the src
+ directory, setting -DPCRE2_CODE_UNIT_WIDTH=8 as a compiler option. Also
+ set -DHAVE_CONFIG_H if you have set up src/config.h with your
+ configuration, or else use other -D settings to change the configuration
+ as required.
+
+ pcre2_auto_possess.c
+ pcre2_chartables.c
+ pcre2_compile.c
+ pcre2_config.c
+ pcre2_context.c
+ pcre2_dfa_match.c
+ pcre2_error.c
+ pcre2_find_bracket.c
+ pcre2_jit_compile.c
+ pcre2_maketables.c
+ pcre2_match.c
+ pcre2_match_data.c
+ pcre2_newline.c
+ pcre2_ord2utf.c
+ pcre2_pattern_info.c
+ pcre2_serialize.c
+ pcre2_string_utils.c
+ pcre2_study.c
+ pcre2_substitute.c
+ pcre2_substring.c
+ pcre2_tables.c
+ pcre2_ucd.c
+ pcre2_valid_utf.c
+ pcre2_xclass.c
+
+ Make sure that you include -I. in the compiler command (or equivalent for
+ an unusual compiler) so that all included PCRE2 header files are first
+ sought in the src directory under the current directory. Otherwise you run
+ the risk of picking up a previously-installed file from somewhere else.
+
+ Note that you must compile pcre2_jit_compile.c, even if you have not
+ defined SUPPORT_JIT in src/config.h, because when JIT support is not
+ configured, dummy functions are compiled. When JIT support IS configured,
+ pcre2_compile.c #includes other files from the sljit subdirectory, where
+ there should be 16 files, all of whose names begin with "sljit". It also
+ #includes src/pcre2_jit_match.c and src/pcre2_jit_misc.c, so you should
+ not compile these yourself.
+
+ (5) Now link all the compiled code into an object library in whichever form
+ your system keeps such libraries. This is the basic PCRE2 C 8-bit library.
+ If your system has static and shared libraries, you may have to do this
+ once for each type.
+
+ (6) If you want to build a 16-bit library or 32-bit library (as well as, or
+ instead of the 8-bit library) just supply 16 or 32 as the value of
+ -DPCRE2_CODE_UNIT_WIDTH when you are compiling.
+
+ (7) If you want to build the POSIX wrapper functions (which apply only to the
+ 8-bit library), ensure that you have the src/pcre2posix.h file and then
+ compile src/pcre2posix.c. Link the result (on its own) as the pcre2posix
+ library.
+
+ (8) The pcre2test program can be linked with any combination of the 8-bit,
+ 16-bit and 32-bit libraries (depending on what you selected in
+ src/config.h). Compile src/pcre2test.c; don't forget -DHAVE_CONFIG_H if
+ necessary, but do NOT define PCRE2_CODE_UNIT_WIDTH. Then link with the
+ appropriate library/ies. If you compiled an 8-bit library, pcre2test also
+ needs the pcre2posix wrapper library.
+
+ (9) Run pcre2test on the testinput files in the testdata directory, and check
+ that the output matches the corresponding testoutput files. There are
+ comments about what each test does in the section entitled "Testing PCRE2"
+ in the README file. If you compiled more than one of the 8-bit, 16-bit and
+ 32-bit libraries, you need to run pcre2test with the -16 option to do
+ 16-bit tests and with the -32 option to do 32-bit tests.
+
+ Some tests are relevant only when certain build-time options are selected.
+ For example, test 4 is for Unicode support, and will not run if you have
+ built PCRE2 without it. See the comments at the start of each testinput
+ file. If you have a suitable Unix-like shell, the RunTest script will run
+ the appropriate tests for you. The command "RunTest list" will output a
+ list of all the tests.
+
+ Note that the supplied files are in Unix format, with just LF characters
+ as line terminators. You may need to edit them to change this if your
+ system uses a different convention.
+
+(10) If you have built PCRE2 with SUPPORT_JIT, the JIT features can be tested
+ by running pcre2test with the -jit option. This is done automatically by
+ the RunTest script. You might also like to build and run the freestanding
+ JIT test program, src/pcre2_jit_test.c.
+
+(11) If you want to use the pcre2grep command, compile and link
+ src/pcre2grep.c; it uses only the basic 8-bit PCRE2 library (it does not
+ need the pcre2posix library).
+
+
+STACK SIZE IN WINDOWS ENVIRONMENTS
+
+The default processor stack size of 1Mb in some Windows environments is too
+small for matching patterns that need much recursion. In particular, test 2 may
+fail because of this. Normally, running out of stack causes a crash, but there
+have been cases where the test program has just died silently. See your linker
+documentation for how to increase stack size if you experience problems. If you
+are using CMake (see "BUILDING PCRE2 ON WINDOWS WITH CMAKE" below) and the gcc
+compiler, you can increase the stack size for pcre2test and pcre2grep by
+setting the CMAKE_EXE_LINKER_FLAGS variable to "-Wl,--stack,8388608" (for
+example). The Linux default of 8Mb is a reasonable choice for the stack, though
+even that can be too small for some pattern/subject combinations.
+
+PCRE2 has a compile configuration option to disable the use of stack for
+recursion so that heap is used instead. However, pattern matching is
+significantly slower when this is done. There is more about stack usage in the
+"pcre2stack" documentation.
+
+
+LINKING PROGRAMS IN WINDOWS ENVIRONMENTS
+
+If you want to statically link a program against a PCRE2 library in the form of
+a non-dll .a file, you must define PCRE2_STATIC before including src/pcre2.h.
+
+
+CALLING CONVENTIONS IN WINDOWS ENVIRONMENTS
+
+It is possible to compile programs to use different calling conventions using
+MSVC. Search the web for "calling conventions" for more information. To make it
+easier to change the calling convention for the exported functions in the
+PCRE2 library, the macro PCRE2_CALL_CONVENTION is present in all the external
+definitions. It can be set externally when compiling (e.g. in CFLAGS). If it is
+not set, it defaults to empty; the default calling convention is then used
+(which is what is wanted most of the time).
+
+
+COMMENTS ABOUT WIN32 BUILDS (see also "BUILDING PCRE2 ON WINDOWS WITH CMAKE")
+
+There are two ways of building PCRE2 using the "configure, make, make install"
+paradigm on Windows systems: using MinGW or using Cygwin. These are not at all
+the same thing; they are completely different from each other. There is also
+support for building using CMake, which some users find a more straightforward
+way of building PCRE2 under Windows.
+
+The MinGW home page (http://www.mingw.org/) says this:
+
+ MinGW: A collection of freely available and freely distributable Windows
+ specific header files and import libraries combined with GNU toolsets that
+ allow one to produce native Windows programs that do not rely on any
+ 3rd-party C runtime DLLs.
+
+The Cygwin home page (http://www.cygwin.com/) says this:
+
+ Cygwin is a Linux-like environment for Windows. It consists of two parts:
+
+ . A DLL (cygwin1.dll) which acts as a Linux API emulation layer providing
+ substantial Linux API functionality
+
+ . A collection of tools which provide Linux look and feel.
+
+On both MinGW and Cygwin, PCRE2 should build correctly using:
+
+ ./configure && make && make install
+
+This should create two libraries called libpcre2-8 and libpcre2-posix. These
+are independent libraries: when you link with libpcre2-posix you must also link
+with libpcre2-8, which contains the basic functions.
+
+Using Cygwin's compiler generates libraries and executables that depend on
+cygwin1.dll. If a library that is generated this way is distributed,
+cygwin1.dll has to be distributed as well. Since cygwin1.dll is under the GPL
+licence, this forces not only PCRE2 to be under the GPL, but also the entire
+application. A distributor who wants to keep their own code proprietary must
+purchase an appropriate Cygwin licence.
+
+MinGW has no such restrictions. The MinGW compiler generates a library or
+executable that can run standalone on Windows without any third party dll or
+licensing issues.
+
+But there is more complication:
+
+If a Cygwin user uses the -mno-cygwin Cygwin gcc flag, what that really does is
+to tell Cygwin's gcc to use the MinGW gcc. Cygwin's gcc is only acting as a
+front end to MinGW's gcc (if you install Cygwin's gcc, you get both Cygwin's
+gcc and MinGW's gcc). So, a user can:
+
+. Build native binaries by using MinGW or by getting Cygwin and using
+ -mno-cygwin.
+
+. Build binaries that depend on cygwin1.dll by using Cygwin with the normal
+ compiler flags.
+
+The test files that are supplied with PCRE2 are in UNIX format, with LF
+characters as line terminators. Unless your PCRE2 library uses a default
+newline option that includes LF as a valid newline, it may be necessary to
+change the line terminators in the test files to get some of the tests to work.
+
+
+BUILDING PCRE2 ON WINDOWS WITH CMAKE
+
+CMake is an alternative configuration facility that can be used instead of
+"configure". CMake creates project files (make files, solution files, etc.)
+tailored to numerous development environments, including Visual Studio,
+Borland, Msys, MinGW, NMake, and Unix. If possible, use short paths with no
+spaces in the names for your CMake installation and your PCRE2 source and build
+directories.
+
+The following instructions were contributed by a PCRE1 user, but they should
+also work for PCRE2. If they are not followed exactly, errors may occur. In the
+event that errors do occur, it is recommended that you delete the CMake cache
+before attempting to repeat the CMake build process. In the CMake GUI, the
+cache can be deleted by selecting "File > Delete Cache".
+
+1. Install the latest CMake version available from http://www.cmake.org/, and
+ ensure that cmake\bin is on your path.
+
+2. Unzip (retaining folder structure) the PCRE2 source tree into a source
+ directory such as C:\pcre2. You should ensure your local date and time
+ is not earlier than the file dates in your source dir if the release is
+ very new.
+
+3. Create a new, empty build directory, preferably a subdirectory of the
+ source dir. For example, C:\pcre2\pcre2-xx\build.
+
+4. Run cmake-gui from the Shell envirornment of your build tool, for example,
+ Msys for Msys/MinGW or Visual Studio Command Prompt for VC/VC++. Do not try
+ to start Cmake from the Windows Start menu, as this can lead to errors.
+
+5. Enter C:\pcre2\pcre2-xx and C:\pcre2\pcre2-xx\build for the source and
+ build directories, respectively.
+
+6. Hit the "Configure" button.
+
+7. Select the particular IDE / build tool that you are using (Visual
+ Studio, MSYS makefiles, MinGW makefiles, etc.)
+
+8. The GUI will then list several configuration options. This is where
+ you can disable Unicode support or select other PCRE2 optional features.
+
+9. Hit "Configure" again. The adjacent "Generate" button should now be
+ active.
+
+10. Hit "Generate".
+
+11. The build directory should now contain a usable build system, be it a
+ solution file for Visual Studio, makefiles for MinGW, etc. Exit from
+ cmake-gui and use the generated build system with your compiler or IDE.
+ E.g., for MinGW you can run "make", or for Visual Studio, open the PCRE2
+ solution, select the desired configuration (Debug, or Release, etc.) and
+ build the ALL_BUILD project.
+
+12. If during configuration with cmake-gui you've elected to build the test
+ programs, you can execute them by building the test project. E.g., for
+ MinGW: "make test"; for Visual Studio build the RUN_TESTS project. The
+ most recent build configuration is targeted by the tests. A summary of
+ test results is presented. Complete test output is subsequently
+ available for review in Testing\Temporary under your build dir.
+
+
+TESTING WITH RUNTEST.BAT
+
+If configured with CMake, building the test project ("make test" or building
+ALL_TESTS in Visual Studio) creates (and runs) pcre2_test.bat (and depending
+on your configuration options, possibly other test programs) in the build
+directory. The pcre2_test.bat script runs RunTest.bat with correct source and
+exe paths.
+
+For manual testing with RunTest.bat, provided the build dir is a subdirectory
+of the source directory: Open command shell window. Chdir to the location
+of your pcre2test.exe and pcre2grep.exe programs. Call RunTest.bat with
+"..\RunTest.Bat" or "..\..\RunTest.bat" as appropriate.
+
+To run only a particular test with RunTest.Bat provide a test number argument.
+
+Otherwise:
+
+1. Copy RunTest.bat into the directory where pcre2test.exe and pcre2grep.exe
+ have been created.
+
+2. Edit RunTest.bat to indentify the full or relative location of
+ the pcre2 source (wherein which the testdata folder resides), e.g.:
+
+ set srcdir=C:\pcre2\pcre2-10.00
+
+3. In a Windows command environment, chdir to the location of your bat and
+ exe programs.
+
+4. Run RunTest.bat. Test outputs will automatically be compared to expected
+ results, and discrepancies will be identified in the console output.
+
+To independently test the just-in-time compiler, run pcre2_jit_test.exe.
+
+
+BUILDING PCRE2 ON NATIVE Z/OS AND Z/VM
+
+z/OS and z/VM are operating systems for mainframe computers, produced by IBM.
+The character code used is EBCDIC, not ASCII or Unicode. In z/OS, UNIX APIs and
+applications can be supported through UNIX System Services, and in such an
+environment PCRE2 can be built in the same way as in other systems. However, in
+native z/OS (without UNIX System Services) and in z/VM, special ports are
+required. For details, please see this web site:
+
+ http://www.zaconsultants.net
+
+The site currently has ports for PCRE1 releases, but PCRE2 should follow in due
+course.
+
+You may also download PCRE1 from WWW.CBTTAPE.ORG, file 882. Everything, source
+and executable, is in EBCDIC and native z/OS file formats and this is the
+recommended download site.

+README file for PCRE2 (Perl-compatible regular expression library)
+------------------------------------------------------------------
+
+PCRE2 is a re-working of the original PCRE library to provide an entirely new
+API. The latest release of PCRE2 is always available in three alternative
+formats from:
+
+ ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/pcre2-xxx.tar.gz
+ ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/pcre2-xxx.tar.bz2
+ ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/pcre2-xxx.zip
+
+There is a mailing list for discussion about the development of PCRE (both the
+original and new APIs) at pcre-dev@exim.org. You can access the archives and
+subscribe or manage your subscription here:
+
+ https://lists.exim.org/mailman/listinfo/pcre-dev
+
+Please read the NEWS file if you are upgrading from a previous release.
+The contents of this README file are:
+
+ The PCRE2 APIs
+ Documentation for PCRE2
+ Contributions by users of PCRE2
+ Building PCRE2 on non-Unix-like systems
+ Building PCRE2 without using autotools
+ Building PCRE2 using autotools
+ Retrieving configuration information
+ Shared libraries
+ Cross-compiling using autotools
+ Making new tarballs
+ Testing PCRE2

+ File manifest
+
+
+The PCRE2 APIs
+--------------
+
+PCRE2 is written in C, and it has its own API. There are three sets of
+functions, one for the 8-bit library, which processes strings of bytes, one for
+the 16-bit library, which processes strings of 16-bit values, and one for the
+32-bit library, which processes strings of 32-bit values. There are no C++
+wrappers.
+
+The distribution does contain a set of C wrapper functions for the 8-bit
+library that are based on the POSIX regular expression API (see the pcre2posix
+man page). These can be found in a library called libpcre2posix. Note that this
+just provides a POSIX calling interface to PCRE2; the regular expressions
+themselves still follow Perl syntax and semantics. The POSIX API is restricted,
+and does not give full access to all of PCRE2's facilities.
+
+The header file for the POSIX-style functions is called pcre2posix.h. The
+official POSIX name is regex.h, but I did not want to risk possible problems
+with existing files of that name by distributing it that way. To use PCRE2 with
+an existing program that uses the POSIX API, pcre2posix.h will have to be
+renamed or pointed at by a link.
+
+If you are using the POSIX interface to PCRE2 and there is already a POSIX
+regex library installed on your system, as well as worrying about the regex.h
+header file (as mentioned above), you must also take care when linking programs
+to ensure that they link with PCRE2's libpcre2posix library. Otherwise they may
+pick up the POSIX functions of the same name from the other library.
+
+One way of avoiding this confusion is to compile PCRE2 with the addition of
+-Dregcomp=PCRE2regcomp (and similarly for the other POSIX functions) to the
+compiler flags (CFLAGS if you are using "configure" -- see below). This has the
+effect of renaming the functions so that the names no longer clash. Of course,
+you have to do the same thing for your applications, or write them using the
+new names.
+
+
+Documentation for PCRE2
+-----------------------
+
+If you install PCRE2 in the normal way on a Unix-like system, you will end up
+with a set of man pages whose names all start with "pcre2". The one that is
+just called "pcre2" lists all the others. In addition to these man pages, the
+PCRE2 documentation is supplied in two other forms:
+
+ 1. There are files called doc/pcre2.txt, doc/pcre2grep.txt, and
+ doc/pcre2test.txt in the source distribution. The first of these is a
+ concatenation of the text forms of all the section 3 man pages except the
+ listing of pcre2demo.c and those that summarize individual functions. The
+ other two are the text forms of the section 1 man pages for the pcre2grep
+ and pcre2test commands. These text forms are provided for ease of scanning
+ with text editors or similar tools. They are installed in
+ <prefix>/share/doc/pcre2, where <prefix> is the installation prefix
+ (defaulting to /usr/local).
+
+ 2. A set of files containing all the documentation in HTML form, hyperlinked
+ in various ways, and rooted in a file called index.html, is distributed in
+ doc/html and installed in <prefix>/share/doc/pcre2/html.
+
+
+Building PCRE2 on non-Unix-like systems
+---------------------------------------
+
+For a non-Unix-like system, please read the comments in the file
+NON-AUTOTOOLS-BUILD, though if your system supports the use of "configure" and
+"make" you may be able to build PCRE2 using autotools in the same way as for
+many Unix-like systems.
+
+PCRE2 can also be configured using CMake, which can be run in various ways
+(command line, GUI, etc). This creates Makefiles, solution files, etc. The file
+NON-AUTOTOOLS-BUILD has information about CMake.
+
+PCRE2 has been compiled on many different operating systems. It should be
+straightforward to build PCRE2 on any system that has a Standard C compiler and
+library, because it uses only Standard C functions.
+
+
+Building PCRE2 without using autotools
+--------------------------------------
+
+The use of autotools (in particular, libtool) is problematic in some
+environments, even some that are Unix or Unix-like. See the NON-AUTOTOOLS-BUILD
+file for ways of building PCRE2 without using autotools.
+
+
+Building PCRE2 using autotools
+------------------------------
+
+The following instructions assume the use of the widely used "configure; make;
+make install" (autotools) process.
+
+To build PCRE2 on system that supports autotools, first run the "configure"
+command from the PCRE2 distribution directory, with your current directory set
+to the directory where you want the files to be created. This command is a
+standard GNU "autoconf" configuration script, for which generic instructions
+are supplied in the file INSTALL.
+
+Most commonly, people build PCRE2 within its own distribution directory, and in
+this case, on many systems, just running "./configure" is sufficient. However,
+the usual methods of changing standard defaults are available. For example:
+
+CFLAGS='-O2 -Wall' ./configure --prefix=/opt/local
+
+This command specifies that the C compiler should be run with the flags '-O2
+-Wall' instead of the default, and that "make install" should install PCRE2
+under /opt/local instead of the default /usr/local.
+
+If you want to build in a different directory, just run "configure" with that
+directory as current. For example, suppose you have unpacked the PCRE2 source
+into /source/pcre2/pcre2-xxx, but you want to build it in
+/build/pcre2/pcre2-xxx:
+
+cd /build/pcre2/pcre2-xxx
+/source/pcre2/pcre2-xxx/configure
+
+PCRE2 is written in C and is normally compiled as a C library. However, it is
+possible to build it as a C++ library, though the provided building apparatus
+does not have any features to support this.
+
+There are some optional features that can be included or omitted from the PCRE2
+library. They are also documented in the pcre2build man page.
+
+. By default, both shared and static libraries are built. You can change this
+ by adding one of these options to the "configure" command:
+
+ --disable-shared
+ --disable-static
+
+ (See also "Shared libraries on Unix-like systems" below.)
+
+. By default, only the 8-bit library is built. If you add --enable-pcre2-16 to
+ the "configure" command, the 16-bit library is also built. If you add
+ --enable-pcre2-32 to the "configure" command, the 32-bit library is also
+ built. If you want only the 16-bit or 32-bit library, use --disable-pcre2-8
+ to disable building the 8-bit library.
+
+. If you want to include support for just-in-time compiling, which can give
+ large performance improvements on certain platforms, add --enable-jit to the
+ "configure" command. This support is available only for certain hardware
+ architectures. If you try to enable it on an unsupported architecture, there
+ will be a compile time error.
+
+. When JIT support is enabled, pcre2grep automatically makes use of it, unless
+ you add --disable-pcre2grep-jit to the "configure" command.
+
+. If you do not want to make use of the support for UTF-8 Unicode character
+ strings in the 8-bit library, UTF-16 Unicode character strings in the 16-bit
+ library, or UTF-32 Unicode character strings in the 32-bit library, you can
+ add --disable-unicode to the "configure" command. This reduces the size of
+ the libraries. It is not possible to configure one library with Unicode
+ support, and another without, in the same configuration.
+
+ When Unicode support is available, the use of a UTF encoding still has to be
+ enabled by setting the PCRE2_UTF option at run time or starting a pattern
+ with (*UTF). When PCRE2 is compiled with Unicode support, its input can only
+ either be ASCII or UTF-8/16/32, even when running on EBCDIC platforms. It is
+ not possible to use both --enable-unicode and --enable-ebcdic at the same
+ time.
+
+ As well as supporting UTF strings, Unicode support includes support for the
+ \P, \p, and \X sequences that recognize Unicode character properties.
+ However, only the basic two-letter properties such as Lu are supported.
+ Escape sequences such as \d and \w in patterns do not by default make use of
+ Unicode properties, but can be made to do so by setting the PCRE2_UCP option
+ or starting a pattern with (*UCP).
+
+. You can build PCRE2 to recognize either CR or LF or the sequence CRLF, or any
+ of the preceding, or any of the Unicode newline sequences, as indicating the
+ end of a line. Whatever you specify at build time is the default; the caller
+ of PCRE2 can change the selection at run time. The default newline indicator
+ is a single LF character (the Unix standard). You can specify the default
+ newline indicator by adding --enable-newline-is-cr, --enable-newline-is-lf,
+ --enable-newline-is-crlf, --enable-newline-is-anycrlf, or
+ --enable-newline-is-any to the "configure" command, respectively.
+
+ If you specify --enable-newline-is-cr or --enable-newline-is-crlf, some of
+ the standard tests will fail, because the lines in the test files end with
+ LF. Even if the files are edited to change the line endings, there are likely
+ to be some failures. With --enable-newline-is-anycrlf or
+ --enable-newline-is-any, many tests should succeed, but there may be some
+ failures.
+
+. By default, the sequence \R in a pattern matches any Unicode line ending
+ sequence. This is independent of the option specifying what PCRE2 considers
+ to be the end of a line (see above). However, the caller of PCRE2 can
+ restrict \R to match only CR, LF, or CRLF. You can make this the default by
+ adding --enable-bsr-anycrlf to the "configure" command (bsr = "backslash R").
+
+. In a pattern, the escape sequence \C matches a single code unit, even in a
+ UTF mode. This can be dangerous because it breaks up multi-code-unit
+ characters. You can build PCRE2 with the use of \C permanently locked out by
+ adding --enable-never-backslash-C (note the upper case C) to the "configure"
+ command. When \C is allowed by the library, individual applications can lock
+ it out by calling pcre2_compile() with the PCRE2_NEVER_BACKSLASH_C option.
+
+. PCRE2 has a counter that limits the depth of nesting of parentheses in a
+ pattern. This limits the amount of system stack that a pattern uses when it
+ is compiled. The default is 250, but you can change it by setting, for
+ example,
+
+ --with-parens-nest-limit=500
+
+. PCRE2 has a counter that can be set to limit the amount of resources it uses
+ when matching a pattern. If the limit is exceeded during a match, the match
+ fails. The default is ten million. You can change the default by setting, for
+ example,
+
+ --with-match-limit=500000
+
+ on the "configure" command. This is just the default; individual calls to
+ pcre2_match() can supply their own value. There is more discussion on the
+ pcre2api man page.
+
+. There is a separate counter that limits the depth of recursive function calls
+ during a matching process. This also has a default of ten million, which is
+ essentially "unlimited". You can change the default by setting, for example,
+
+ --with-match-limit-recursion=500000
+
+ Recursive function calls use up the runtime stack; running out of stack can
+ cause programs to crash in strange ways. There is a discussion about stack
+ sizes in the pcre2stack man page.
+
+. In the 8-bit library, the default maximum compiled pattern size is around
+ 64K. You can increase this by adding --with-link-size=3 to the "configure"
+ command. PCRE2 then uses three bytes instead of two for offsets to different
+ parts of the compiled pattern. In the 16-bit library, --with-link-size=3 is
+ the same as --with-link-size=4, which (in both libraries) uses four-byte
+ offsets. Increasing the internal link size reduces performance in the 8-bit
+ and 16-bit libraries. In the 32-bit library, the link size setting is
+ ignored, as 4-byte offsets are always used.
+
+. You can build PCRE2 so that its internal match() function that is called from
+ pcre2_match() does not call itself recursively. Instead, it uses memory
+ blocks obtained from the heap to save data that would otherwise be saved on
+ the stack. To build PCRE2 like this, use
+
+ --disable-stack-for-recursion
+
+ on the "configure" command. PCRE2 runs more slowly in this mode, but it may
+ be necessary in environments with limited stack sizes. This applies only to
+ the normal execution of the pcre2_match() function; if JIT support is being
+ successfully used, it is not relevant. Equally, it does not apply to
+ pcre2_dfa_match(), which does not use deeply nested recursion. There is a
+ discussion about stack sizes in the pcre2stack man page.
+
+. For speed, PCRE2 uses four tables for manipulating and identifying characters
+ whose code point values are less than 256. By default, it uses a set of
+ tables for ASCII encoding that is part of the distribution. If you specify
+
+ --enable-rebuild-chartables
+
+ a program called dftables is compiled and run in the default C locale when
+ you obey "make". It builds a source file called pcre2_chartables.c. If you do
+ not specify this option, pcre2_chartables.c is created as a copy of
+ pcre2_chartables.c.dist. See "Character tables" below for further
+ information.
+
+. It is possible to compile PCRE2 for use on systems that use EBCDIC as their
+ character code (as opposed to ASCII/Unicode) by specifying
+
+ --enable-ebcdic --disable-unicode
+
+ This automatically implies --enable-rebuild-chartables (see above). However,
+ when PCRE2 is built this way, it always operates in EBCDIC. It cannot support
+ both EBCDIC and UTF-8/16/32. There is a second option, --enable-ebcdic-nl25,
+ which specifies that the code value for the EBCDIC NL character is 0x25
+ instead of the default 0x15.
+
+. If you specify --enable-debug, additional debugging code is included in the
+ build. This option is intended for use by the PCRE2 maintainers.
+
+. In environments where valgrind is installed, if you specify
+
+ --enable-valgrind
+
+ PCRE2 will use valgrind annotations to mark certain memory regions as
+ unaddressable. This allows it to detect invalid memory accesses, and is
+ mostly useful for debugging PCRE2 itself.
+
+. In environments where the gcc compiler is used and lcov version 1.6 or above
+ is installed, if you specify
+
+ --enable-coverage
+
+ the build process implements a code coverage report for the test suite. The
+ report is generated by running "make coverage". If ccache is installed on
+ your system, it must be disabled when building PCRE2 for coverage reporting.
+ You can do this by setting the environment variable CCACHE_DISABLE=1 before
+ running "make" to build PCRE2. There is more information about coverage
+ reporting in the "pcre2build" documentation.
+
+. The pcre2grep program currently supports only 8-bit data files, and so
+ requires the 8-bit PCRE2 library. It is possible to compile pcre2grep to use
+ libz and/or libbz2, in order to read .gz and .bz2 files (respectively), by
+ specifying one or both of
+
+ --enable-pcre2grep-libz
+ --enable-pcre2grep-libbz2
+
+ Of course, the relevant libraries must be installed on your system.
+
+. The default size (in bytes) of the internal buffer used by pcre2grep can be
+ set by, for example:
+
+ --with-pcre2grep-bufsize=51200
+
+ The value must be a plain integer. The default is 20480.
+
+. It is possible to compile pcre2test so that it links with the libreadline
+ or libedit libraries, by specifying, respectively,
+
+ --enable-pcre2test-libreadline or --enable-pcre2test-libedit
+
+ If this is done, when pcre2test's input is from a terminal, it reads it using
+ the readline() function. This provides line-editing and history facilities.
+ Note that libreadline is GPL-licenced, so if you distribute a binary of
+ pcre2test linked in this way, there may be licensing issues. These can be
+ avoided by linking with libedit (which has a BSD licence) instead.
+
+ Enabling libreadline causes the -lreadline option to be added to the
+ pcre2test build. In many operating environments with a sytem-installed
+ readline library this is sufficient. However, in some environments (e.g. if
+ an unmodified distribution version of readline is in use), it may be
+ necessary to specify something like LIBS="-lncurses" as well. This is
+ because, to quote the readline INSTALL, "Readline uses the termcap functions,
+ but does not link with the termcap or curses library itself, allowing
+ applications which link with readline the to choose an appropriate library."
+ If you get error messages about missing functions tgetstr, tgetent, tputs,
+ tgetflag, or tgoto, this is the problem, and linking with the ncurses library
+ should fix it.
+
+The "configure" script builds the following files for the basic C library:
+
+. Makefile the makefile that builds the library
+. src/config.h build-time configuration options for the library
+. src/pcre2.h the public PCRE2 header file
+. pcre2-config script that shows the building settings such as CFLAGS
+ that were set for "configure"
+. libpcre2-8.pc )
+. libpcre2-16.pc ) data for the pkg-config command
+. libpcre2-32.pc )
+. libpcre2-posix.pc )
+. libtool script that builds shared and/or static libraries
+
+Versions of config.h and pcre2.h are distributed in the src directory of PCRE2
+tarballs under the names config.h.generic and pcre2.h.generic. These are
+provided for those who have to build PCRE2 without using "configure" or CMake.
+If you use "configure" or CMake, the .generic versions are not used.
+
+The "configure" script also creates config.status, which is an executable
+script that can be run to recreate the configuration, and config.log, which
+contains compiler output from tests that "configure" runs.
+
+Once "configure" has run, you can run "make". This builds whichever of the
+libraries libpcre2-8, libpcre2-16 and libpcre2-32 are configured, and a test
+program called pcre2test. If you enabled JIT support with --enable-jit, another
+test program called pcre2_jit_test is built as well. If the 8-bit library is
+built, libpcre2-posix and the pcre2grep command are also built. Running
+"make" with the -j option may speed up compilation on multiprocessor systems.
+
+The command "make check" runs all the appropriate tests. Details of the PCRE2
+tests are given below in a separate section of this document. The -j option of
+"make" can also be used when running the tests.
+
+You can use "make install" to install PCRE2 into live directories on your
+system. The following are installed (file names are all relative to the
+<prefix> that is set when "configure" is run):
+
+ Commands (bin):
+ pcre2test
+ pcre2grep (if 8-bit support is enabled)
+ pcre2-config
+
+ Libraries (lib):
+ libpcre2-8 (if 8-bit support is enabled)
+ libpcre2-16 (if 16-bit support is enabled)
+ libpcre2-32 (if 32-bit support is enabled)
+ libpcre2-posix (if 8-bit support is enabled)
+
+ Configuration information (lib/pkgconfig):
+ libpcre2-8.pc
+ libpcre2-16.pc
+ libpcre2-32.pc
+ libpcre2-posix.pc
+
+ Header files (include):

+ pcre2posix.h
+
+ Man pages (share/man/man{1,3}):

+
+If you want to remove PCRE2 from your system, you can run "make uninstall".
+This removes all the files that "make install" installed. However, it does not
+remove any directories, because these are often shared with other programs.
+
+
+Retrieving configuration information
+------------------------------------
+
+Running "make install" installs the command pcre2-config, which can be used to
+recall information about the PCRE2 configuration and installation. For example:
+
+ pcre2-config --version
+
+prints the version number, and
+
+ pcre2-config --libs8
+
+outputs information about where the 8-bit library is installed. This command
+can be included in makefiles for programs that use PCRE2, saving the programmer
+from having to remember too many details. Run pcre2-config with no arguments to
+obtain a list of possible arguments.
+
+The pkg-config command is another system for saving and retrieving information
+about installed libraries. Instead of separate commands for each library, a
+single command is used. For example:
+
+ pkg-config --libs libpcre2-16
+
+The data is held in *.pc files that are installed in a directory called
+<prefix>/lib/pkgconfig.
+
+
+Shared libraries
+----------------
+
+The default distribution builds PCRE2 as shared libraries and static libraries,
+as long as the operating system supports shared libraries. Shared library
+support relies on the "libtool" script which is built as part of the
+"configure" process.
+
+The libtool script is used to compile and link both shared and static
+libraries. They are placed in a subdirectory called .libs when they are newly
+built. The programs pcre2test and pcre2grep are built to use these uninstalled
+libraries (by means of wrapper scripts in the case of shared libraries). When
+you use "make install" to install shared libraries, pcre2grep and pcre2test are
+automatically re-built to use the newly installed shared libraries before being
+installed themselves. However, the versions left in the build directory still
+use the uninstalled libraries.
+
+To build PCRE2 using static libraries only you must use --disable-shared when
+configuring it. For example:
+
+./configure --prefix=/usr/gnu --disable-shared
+
+Then run "make" in the usual way. Similarly, you can use --disable-static to
+build only shared libraries.
+
+
+Cross-compiling using autotools
+-------------------------------
+
+You can specify CC and CFLAGS in the normal way to the "configure" command, in
+order to cross-compile PCRE2 for some other host. However, you should NOT
+specify --enable-rebuild-chartables, because if you do, the dftables.c source
+file is compiled and run on the local host, in order to generate the inbuilt
+character tables (the pcre2_chartables.c file). This will probably not work,
+because dftables.c needs to be compiled with the local compiler, not the cross
+compiler.
+
+When --enable-rebuild-chartables is not specified, pcre2_chartables.c is
+created by making a copy of pcre2_chartables.c.dist, which is a default set of
+tables that assumes ASCII code. Cross-compiling with the default tables should
+not be a problem.
+
+If you need to modify the character tables when cross-compiling, you should
+move pcre2_chartables.c.dist out of the way, then compile dftables.c by hand
+and run it on the local host to make a new version of pcre2_chartables.c.dist.
+Then when you cross-compile PCRE2 this new version of the tables will be used.
+
+
+Making new tarballs
+-------------------
+
+The command "make dist" creates three PCRE2 tarballs, in tar.gz, tar.bz2, and
+zip formats. The command "make distcheck" does the same, but then does a trial
+build of the new distribution to ensure that it works.
+
+If you have modified any of the man page sources in the doc directory, you
+should first run the PrepareRelease script before making a distribution. This
+script creates the .txt and HTML forms of the documentation from the man pages.
+
+
+Testing PCRE2
+------------
+
+To test the basic PCRE2 library on a Unix-like system, run the RunTest script.
+There is another script called RunGrepTest that tests the pcre2grep command.
+When JIT support is enabled, a third test program called pcre2_jit_test is
+built. Both the scripts and all the program tests are run if you obey "make
+check". For other environments, see the instructions in NON-AUTOTOOLS-BUILD.
+
+The RunTest script runs the pcre2test test program (which is documented in its
+own man page) on each of the relevant testinput files in the testdata
+directory, and compares the output with the contents of the corresponding
+testoutput files. RunTest uses a file called testtry to hold the main output
+from pcre2test. Other files whose names begin with "test" are used as working
+files in some tests.
+
+Some tests are relevant only when certain build-time options were selected. For
+example, the tests for UTF-8/16/32 features are run only when Unicode support
+is available. RunTest outputs a comment when it skips a test.
+
+Many (but not all) of the tests that are not skipped are run twice if JIT
+support is available. On the second run, JIT compilation is forced. This
+testing can be suppressed by putting "nojit" on the RunTest command line.
+
+The entire set of tests is run once for each of the 8-bit, 16-bit and 32-bit
+libraries that are enabled. If you want to run just one set of tests, call
+RunTest with either the -8, -16 or -32 option.
+
+If valgrind is installed, you can run the tests under it by putting "valgrind"
+on the RunTest command line. To run pcre2test on just one or more specific test
+files, give their numbers as arguments to RunTest, for example:
+
+ RunTest 2 7 11
+
+You can also specify ranges of tests such as 3-6 or 3- (meaning 3 to the
+end), or a number preceded by ~ to exclude a test. For example:
+
+ Runtest 3-15 ~10
+
+This runs tests 3 to 15, excluding test 10, and just ~13 runs all the tests
+except test 13. Whatever order the arguments are in, the tests are always run
+in numerical order.
+
+You can also call RunTest with the single argument "list" to cause it to output
+a list of tests.
+
+The test sequence starts with "test 0", which is a special test that has no
+input file, and whose output is not checked. This is because it will be
+different on different hardware and with different configurations. The test
+exists in order to exercise some of pcre2test's code that would not otherwise
+be run.
+
+Tests 1 and 2 can always be run, as they expect only plain text strings (not
+UTF) and make no use of Unicode properties. The first test file can be fed
+directly into the perltest.sh script to check that Perl gives the same results.
+The only difference you should see is in the first few lines, where the Perl
+version is given instead of the PCRE2 version. The second set of tests check
+auxiliary functions, error detection, and run-time flags that are specific to
+PCRE2. It also uses the debugging flags to check some of the internals of
+pcre2_compile().
+
+If you build PCRE2 with a locale setting that is not the standard C locale, the
+character tables may be different (see next paragraph). In some cases, this may
+cause failures in the second set of tests. For example, in a locale where the
+isprint() function yields TRUE for characters in the range 128-255, the use of
+[:isascii:] inside a character class defines a different set of characters, and
+this shows up in this test as a difference in the compiled code, which is being
+listed for checking. For example, where the comparison test output contains
+[\x00-\x7f] the test might contain [\x00-\xff], and similarly in some other
+cases. This is not a bug in PCRE2.
+
+Test 3 checks pcre2_maketables(), the facility for building a set of character
+tables for a specific locale and using them instead of the default tables. The
+script uses the "locale" command to check for the availability of the "fr_FR",
+"french", or "fr" locale, and uses the first one that it finds. If the "locale"
+command fails, or if its output doesn't include "fr_FR", "french", or "fr" in
+the list of available locales, the third test cannot be run, and a comment is
+output to say why. If running this test produces an error like this:
+
+ ** Failed to set locale "fr_FR"
+
+it means that the given locale is not available on your system, despite being
+listed by "locale". This does not mean that PCRE2 is broken. There are three
+alternative output files for the third test, because three different versions
+of the French locale have been encountered. The test passes if its output
+matches any one of them.
+
+Tests 4 and 5 check UTF and Unicode property support, test 4 being compatible
+with the perltest.sh script, and test 5 checking PCRE2-specific things.
+
+Tests 6 and 7 check the pcre2_dfa_match() alternative matching function, in
+non-UTF mode and UTF-mode with Unicode property support, respectively.
+
+Test 8 checks some internal offsets and code size features; it is run only when
+the default "link size" of 2 is set (in other cases the sizes change) and when
+Unicode support is enabled.
+
+Tests 9 and 10 are run only in 8-bit mode, and tests 11 and 12 are run only in
+16-bit and 32-bit modes. These are tests that generate different output in
+8-bit mode. Each pair are for general cases and Unicode support, respectively.
+Test 13 checks the handling of non-UTF characters greater than 255 by
+pcre2_dfa_match() in 16-bit and 32-bit modes.
+
+Test 14 contains a number of tests that must not be run with JIT. They check,
+among other non-JIT things, the match-limiting features of the intepretive
+matcher.
+
+Test 15 is run only when JIT support is not available. It checks that an
+attempt to use JIT has the expected behaviour.
+
+Test 16 is run only when JIT support is available. It checks JIT complete and
+partial modes, match-limiting under JIT, and other JIT-specific features.
+
+Tests 17 and 18 are run only in 8-bit mode. They check the POSIX interface to
+the 8-bit library, without and with Unicode support, respectively.
+
+Test 19 checks the serialization functions by writing a set of compiled
+patterns to a file, and then reloading and checking them.
+
+
+Character tables
+----------------
+
+For speed, PCRE2 uses four tables for manipulating and identifying characters
+whose code point values are less than 256. By default, a set of tables that is
+built into the library is used. The pcre2_maketables() function can be called
+by an application to create a new set of tables in the current locale. This are
+passed to PCRE2 by calling pcre2_set_character_tables() to put a pointer into a
+compile context.
+
+The source file called pcre2_chartables.c contains the default set of tables.
+By default, this is created as a copy of pcre2_chartables.c.dist, which
+contains tables for ASCII coding. However, if --enable-rebuild-chartables is
+specified for ./configure, a different version of pcre2_chartables.c is built
+by the program dftables (compiled from dftables.c), which uses the ANSI C
+character handling functions such as isalnum(), isalpha(), isupper(),
+islower(), etc. to build the table sources. This means that the default C
+locale which is set for your system will control the contents of these default
+tables. You can change the default tables by editing pcre2_chartables.c and
+then re-building PCRE2. If you do this, you should take care to ensure that the
+file does not get automatically re-generated. The best way to do this is to
+move pcre2_chartables.c.dist out of the way and replace it with your customized
+tables.
+
+When the dftables program is run as a result of --enable-rebuild-chartables,
+it uses the default C locale that is set on your system. It does not pay
+attention to the LC_xxx environment variables. In other words, it uses the
+system's default locale rather than whatever the compiling user happens to have
+set. If you really do want to build a source set of character tables in a
+locale that is specified by the LC_xxx variables, you can run the dftables
+program by hand with the -L option. For example:
+
+ ./dftables -L pcre2_chartables.c.special
+
+The first two 256-byte tables provide lower casing and case flipping functions,
+respectively. The next table consists of three 32-byte bit maps which identify
+digits, "word" characters, and white space, respectively. These are used when
+building 32-byte bit maps that represent character classes for code points less
+than 256. The final 256-byte table has bits indicating various character types,
+as follows:
+
+ 1 white space character
+ 2 letter
+ 4 decimal digit
+ 8 hexadecimal digit
+ 16 alphanumeric or '_'
+ 128 regular expression metacharacter or binary zero
+
+You should not alter the set of characters that contain the 128 bit, as that
+will cause PCRE2 to malfunction.

+PCRE2 is the name used for a revised API for the PCRE library, which is a set
+of functions, written in C, that implement regular expression pattern matching
+using the same syntax and semantics as Perl, with just a few differences. Some
+features that appeared in Python and the original PCRE before they appeared in

+</P>
+<P>
+The source code for PCRE2 can be compiled to support 8-bit, 16-bit, or 32-bit
+code units, which means that up to three separate libraries may be installed.
+The original work to extend PCRE to 16-bit and 32-bit code units was done by
+Zoltan Herczeg and Christian Persch, respectively. In all three cases, strings
+can be interpreted either as one character per code unit, or as UTF-encoded
+Unicode, with support for Unicode general category properties. Unicode support
+is optional at build time (but is the default). However, processing strings as
+UTF code units must be enabled explicitly at run time. The version of Unicode
+in use can be discovered by running
+<pre>
+ pcre2test -C
+</PRE>
+</P>
+<P>
+The three libraries contain identical sets of functions, with names ending in
+_8, _16, or _32, respectively (for example, <b>pcre2_compile_8()</b>). However,
+by defining PCRE2_CODE_UNIT_WIDTH to be 8, 16, or 32, a program that uses just
+one code unit width can be written using generic names such as
+<b>pcre2_compile()</b>, and the documentation is written assuming that this is
+the case.
+</P>
+<P>
+In addition to the Perl-compatible matching function, PCRE2 contains an
+alternative function that matches the same compiled patterns in a different
+way. In certain circumstances, the alternative function has some advantages.
+For a discussion of the two matching algorithms, see the
+<a href="pcre2matching.html"><b>pcre2matching</b></a>
+page.
+</P>
+<P>
+Details of exactly which Perl regular expression features are and are not
+supported by PCRE2 are given in separate documents. See the
+<a href="pcre2pattern.html"><b>pcre2pattern</b></a>
+and
+<a href="pcre2compat.html"><b>pcre2compat</b></a>
+pages. There is a syntax summary in the
+<a href="pcre2syntax.html"><b>pcre2syntax</b></a>
+page.
+</P>
+<P>
+Some features of PCRE2 can be included, excluded, or changed when the library
+is built. The
+<a href="pcre2_config.html"><b>pcre2_config()</b></a>
+function makes it possible for a client to discover which features are
+available. The features themselves are described in the
+<a href="pcre2build.html"><b>pcre2build</b></a>
+page. Documentation about building PCRE2 for various operating systems can be
+found in the
+<a href="README.txt"><b>README</b></a>
+and
+<a href="NON-AUTOTOOLS-BUILD.txt"><b>NON-AUTOTOOLS_BUILD</b></a>
+files in the source distribution.
+</P>
+<P>
+The libraries contains a number of undocumented internal functions and data
+tables that are used by more than one of the exported external functions, but
+which are not intended for use by external callers. Their names all begin with
+"_pcre2", which hopefully will not provoke any name clashes. In some
+environments, it is possible to control which external symbols are exported
+when a shared library is built, and in these cases the undocumented symbols are
+not exported.
+</P>
+<br><a name="SEC2" href="#TOC1">SECURITY CONSIDERATIONS</a><br>
+<P>
+If you are using PCRE2 in a non-UTF application that permits users to supply
+arbitrary patterns for compilation, you should be aware of a feature that
+allows users to turn on UTF support from within a pattern. For example, an
+8-bit pattern that begins with "(*UTF)" turns on UTF-8 mode, which interprets
+patterns and subjects as strings of UTF-8 code units instead of individual
+8-bit characters. This causes both the pattern and any data against which it is
+matched to be checked for UTF-8 validity. If the data string is very long, such
+a check might use sufficiently many resources as to cause your application to
+lose performance.
+</P>
+<P>
+One way of guarding against this possibility is to use the
+<b>pcre2_pattern_info()</b> function to check the compiled pattern's options for
+PCRE2_UTF. Alternatively, you can set the PCRE2_NEVER_UTF option when calling
+<b>pcre2_compile()</b>. This causes an compile time error if a pattern contains
+a UTF-setting sequence.
+</P>
+<P>
+The use of Unicode properties for character types such as \d can also be
+enabled from within the pattern, by specifying "(*UCP)". This feature can be
+disallowed by setting the PCRE2_NEVER_UCP option.
+</P>
+<P>
+If your application is one that supports UTF, be aware that validity checking
+can take time. If the same data string is to be matched many times, you can use
+the PCRE2_NO_UTF_CHECK option for the second and subsequent matches to avoid
+running redundant checks.
+</P>
+<P>
+The use of the \C escape sequence in a UTF-8 or UTF-16 pattern can lead to
+problems, because it may leave the current matching point in the middle of a
+multi-code-unit character. The PCRE2_NEVER_BACKSLASH_C option can be used by an
+application to lock out the use of \C, causing a compile-time error if it is
+encountered. It is also possible to build PCRE2 with the use of \C permanently
+disabled.
+</P>
+<P>
+Another way that performance can be hit is by running a pattern that has a very
+large search tree against a string that will never match. Nested unlimited
+repeats in a pattern are a common example. PCRE2 provides some protection
+against this: see the <b>pcre2_set_match_limit()</b> function in the
+<a href="pcre2api.html"><b>pcre2api</b></a>
+page.
+</P>
+<br><a name="SEC3" href="#TOC1">USER DOCUMENTATION</a><br>
+<P>
+The user documentation for PCRE2 comprises a number of different sections. In
+the "man" format, each of these is a separate "man page". In the HTML format,
+each is a separate page, linked from the index page. In the plain text format,
+the descriptions of the <b>pcre2grep</b> and <b>pcre2test</b> programs are in
+files called <b>pcre2grep.txt</b> and <b>pcre2test.txt</b>, respectively. The
+remaining sections, except for the <b>pcre2demo</b> section (which is a program
+listing), and the short pages for individual functions, are concatenated in
+<b>pcre2.txt</b>, for ease of searching. The sections are as follows:
+<pre>

+DESCRIPTION
+</b><br>
+<P>
+This function makes it possible for a client program to find out which optional
+features are available in the version of the PCRE2 library it is using. The
+arguments are as follows:
+<pre>
+ <i>what</i> A code specifying what information is required
+ <i>where</i> Points to where to put the information
+</pre>
+If <i>where</i> is NULL, the function returns the amount of memory needed for
+the requested information. When the information is a string, the value is in
+code units; for other types of data it is in bytes.
+</P>
+<P>
+If <b>where</b> is not NULL, for PCRE2_CONFIG_JITTARGET,
+PCRE2_CONFIG_UNICODE_VERSION, and PCRE2_CONFIG_VERSION it must point to a
+buffer that is large enough to hold the string. For all other codes it must
+point to a uint32_t integer variable. The available codes are:
+<pre>
+ PCRE2_CONFIG_BSR Indicates what \R matches by default:
+ PCRE2_BSR_UNICODE
+ PCRE2_BSR_ANYCRLF
+ PCRE2_CONFIG_JIT Availability of just-in-time compiler
+ support (1=yes 0=no)
+ PCRE2_CONFIG_JITTARGET Information about the target archi-
+ tecture for the JIT compiler
+ PCRE2_CONFIG_LINKSIZE Configured internal link size (2, 3, 4)
+ PCRE2_CONFIG_MATCHLIMIT Default internal resource limit
+ PCRE2_CONFIG_NEWLINE Code for the default newline sequence:
+ PCRE2_NEWLINE_CR
+ PCRE2_NEWLINE_LF
+ PCRE2_NEWLINE_CRLF
+ PCRE2_NEWLINE_ANY
+ PCRE2_NEWLINE_ANYCRLF
+ PCRE2_CONFIG_PARENSLIMIT Default parentheses nesting limit
+ PCRE2_CONFIG_RECURSIONLIMIT Internal recursion depth limit
+ PCRE2_CONFIG_STACKRECURSE Recursion implementation (1=stack
+ 0=heap)
+ PCRE2_CONFIG_UNICODE Availability of Unicode support (1=yes
+ 0=no)
+ PCRE2_CONFIG_UNICODE_VERSION The Unicode version (a string)
+ PCRE2_CONFIG_VERSION The PCRE2 version (a string)
+</pre>
+The function yields a non-negative value on success or the negative value

+DESCRIPTION
+</b><br>
+<P>
+This function matches a compiled regular expression against a given subject
+string, using an alternative matching algorithm that scans the subject string
+just once (<i>not</i> Perl-compatible). (The Perl-compatible matching function
+is <b>pcre2_match()</b>.) The arguments for this function are:
+<pre>
+ <i>code</i> Points to the compiled pattern
+ <i>subject</i> Points to the subject string
+ <i>length</i> Length of the subject string
+ <i>startoffset</i> Offset in the subject at which to start matching
+ <i>options</i> Option bits
+ <i>match_data</i> Points to a match data block, for results
+ <i>mcontext</i> Points to a match context, or is NULL
+ <i>workspace</i> Points to a vector of ints used as working space
+ <i>wscount</i> Number of elements in the vector
+</pre>
+For <b>pcre2_dfa_match()</b>, a match context is needed only if you want to set
+up a callout function. The <i>length</i> and <i>startoffset</i> values are code
+units, not characters. The options are:
+<pre>
+ PCRE2_ANCHORED Match only at the first position
+ PCRE2_NOTBOL Subject is not the beginning of a line
+ PCRE2_NOTEOL Subject is not the end of a line
+ PCRE2_NOTEMPTY An empty string is not a valid match
+ PCRE2_NOTEMPTY_ATSTART An empty string at the start of the subject
+ is not a valid match
+ PCRE2_NO_UTF_CHECK Do not check the subject for UTF
+ validity (only relevant if PCRE2_UTF
+ was set at compile time)
+ PCRE2_PARTIAL_SOFT Return PCRE2_ERROR_PARTIAL for a partial
+ match if no full matches are found
+ PCRE2_PARTIAL_HARD Return PCRE2_ERROR_PARTIAL for a partial match
+ even if there is a full match as well
+ PCRE2_DFA_RESTART Restart after a partial match
+ PCRE2_DFA_SHORTEST Return only the shortest match
+</pre>
+There are restrictions on what may appear in a pattern when using this matching
+function. Details are given in the
+<a href="pcre2matching.html"><b>pcre2matching</b></a>
+documentation. For details of partial matching, see the

+<br><b>
+DESCRIPTION
+</b><br>
+<P>
+This function provides control over the memory used by JIT as a run-time stack
+when <b>pcre2_match()</b> or <b>pcre2_jit_match()</b> is called with a pattern
+that has been successfully processed by the JIT compiler. The information that
+determines which stack is used is put into a match context that is subsequently
+passed to a matching function. The arguments of this function are:
+<pre>
+ mcontext a pointer to a match context
+ callback a callback function
+ callback_data a JIT stack or a value to be passed to the callback
+</PRE>
+</P>
+<P>
+If <i>callback</i> is NULL and <i>callback_data</i> is NULL, an internal 32K
+block on the machine stack is used.
+</P>
+<P>
+If <i>callback</i> is NULL and <i>callback_data</i> is not NULL,
+<i>callback_data</i> must be a valid JIT stack, the result of calling
+<b>pcre2_jit_stack_create()</b>.
+</P>
+<P>
+If <i>callback</i> not NULL, it is called with <i>callback_data</i> as an
+argument at the start of matching, in order to set up a JIT stack. If the
+result is NULL, the internal 32K stack is used; otherwise the return value must
+be a valid JIT stack, the result of calling <b>pcre2_jit_stack_create()</b>.
+</P>
+<P>
+You may safely use the same JIT stack for multiple patterns, as long as they
+are all matched in the same thread. In a multithread application, each thread
+must use its own JIT stack. For more details, see the

+<br><b>
+DESCRIPTION
+</b><br>
+<P>
+This function is used to create a stack for use by the code compiled by the JIT
+compiler. The first two arguments are a starting size for the stack, and a
+maximum size to which it is allowed to grow. The final argument is a general
+context, for memory allocation functions, or NULL for standard memory
+allocation. The result can be passed to the JIT run-time code by calling
+<b>pcre2_jit_stack_assign()</b> to associate the stack with a compiled pattern,
+which can then be processed by <b>pcre2_match()</b>. If the "fast path" JIT
+matcher, <b>pcre2_jit_match()</b> is used, the stack can be passed directly as
+an argument. A maximum stack size of 512K to 1M should be more than enough for
+any pattern. For more details, see the

+DESCRIPTION

+<P>
+This function creates a new match data block, which is used for holding the
+result of a match. The first argument points to a compiled pattern. The number
+of capturing parentheses within the pattern is used to compute the number of
+pairs of offsets that are required in the match data block. These form the
+"output vector" (ovector) within the match data block, and are used to identify
+the matched string and any captured substrings.
+</P>
+<P>
+The second argument points to a general context, for custom memory management,
+or is NULL to use the same memory allocator as was used for the compiled
+pattern. The result of the function is NULL if the memory for the block could
+not be obtained.

+DESCRIPTION
+</b><br>
+<P>
+This function matches a compiled regular expression against a given subject
+string, using a matching algorithm that is similar to Perl's. It then makes a
+copy of the subject, substituting a replacement string for what was matched.
+Its arguments are:
+<pre>
+ <i>code</i> Points to the compiled pattern
+ <i>subject</i> Points to the subject string
+ <i>length</i> Length of the subject string
+ <i>startoffset</i> Offset in the subject at which to start matching
+ <i>options</i> Option bits
+ <i>match_data</i> Points to a match data block, or is NULL
+ <i>mcontext</i> Points to a match context, or is NULL
+ <i>replacement</i> Points to the replacement string
+ <i>rlength</i> Length of the replacement string
+ <i>outputbuffer</i> Points to the output buffer
+ <i>outlengthptr</i> Points to the length of the output buffer
+</pre>
+A match context is needed only if you want to:
+<pre>
+ Set up a callout function
+ Change the limit for calling the internal function <i>match()</i>
+ Change the limit for calling <i>match()</i> recursively
+ Set custom memory management when the heap is used for recursion
+</pre>
+The <i>length</i>, <i>startoffset</i> and <i>rlength</i> values are code
+units, not characters, as is the contents of the variable pointed at by
+<i>outlengthptr</i>, which is updated to the actual length of the new string.
+The options are:
+<pre>
+ PCRE2_ANCHORED Match only at the first position
+ PCRE2_NOTBOL Subject is not the beginning of a line
+ PCRE2_NOTEOL Subject is not the end of a line
+ PCRE2_NOTEMPTY An empty string is not a valid match
+ PCRE2_NOTEMPTY_ATSTART An empty string at the start of the
+ subject is not a valid match
+ PCRE2_NO_UTF_CHECK Do not check the subject or replacement
+ for UTF validity (only relevant if
+ PCRE2_UTF was set at compile time)
+ PCRE2_SUBSTITUTE_EXTENDED Do extended replacement processing
+ PCRE2_SUBSTITUTE_GLOBAL Replace all occurrences in the subject
+ PCRE2_SUBSTITUTE_OVERFLOW_LENGTH If overflow, compute needed length
+ PCRE2_SUBSTITUTE_UNKNOWN_UNSET Treat unknown group as unset
+ PCRE2_SUBSTITUTE_UNSET_EMPTY Simple unset insert = empty string
+</pre>
+The function returns the number of substitutions, which may be zero if there
+were no matches. The result can be greater than one only when
+PCRE2_SUBSTITUTE_GLOBAL is set. In the event of an error, a negative error code
+is returned.

+This is a convenience function for extracting a captured substring by name into

+ <i>bufferptr</i> Where to put the string pointer
+ <i>bufflen</i> Where to put the string length
+</pre>
+The memory in which the substring is placed is obtained by calling the same

+it is no longer needed. The yield of the function is zero for success or one of
+the following error numbers:
+<pre>
+ PCRE2_ERROR_NOSUBSTRING there are no groups of that name
+ PCRE2_ERROR_UNAVAILBLE the ovector was too small for that group
+ PCRE2_ERROR_UNSET the group did not participate in the match
+ PCRE2_ERROR_NOMEMORY memory could not be obtained
+</pre>
+If there is more than one group with the given name, the first one that is set
+is returned. In this situation PCRE2_ERROR_UNSET means that no group with the
+given name was set.

+This is a convenience function for extracting all the captured substrings after

+<pre>
+ <i>match_data</i> The match data block
+ <i>listptr</i> Where to put a pointer to the list
+ <i>lengthsptr</i> Where to put a pointer to the lengths, or NULL
+</pre>
+A pointer to a list of pointers is put in the variable whose address is in
+<i>listptr</i>. The list is terminated by a NULL pointer. If <i>lengthsptr</i> is
+not NULL, a matching list of lengths is created, and its address is placed in
+<i>lengthsptr</i>. The yield of the function is zero on success or
+PCRE2_ERROR_NOMEMORY if sufficient memory could not be obtained.

+<br><a name="SEC11" href="#TOC1">PCRE2 8-BIT, 16-BIT, AND 32-BIT LIBRARIES</a><br>
+<P>
+There are three PCRE2 libraries, supporting 8-bit, 16-bit, and 32-bit code
+units, respectively. However, there is just one header file, <b>pcre2.h</b>.
+This contains the function prototypes and other definitions for all three
+libraries. One, two, or all three can be installed simultaneously. On Unix-like
+systems the libraries are called <b>libpcre2-8</b>, <b>libpcre2-16</b>, and
+<b>libpcre2-32</b>, and they can also co-exist with the original PCRE libraries.
+</P>
+<P>
+Character strings are passed to and from a PCRE2 library as a sequence of
+unsigned integers in code units of the appropriate width. Every PCRE2 function
+comes in three different forms, one for each library, for example:
+<pre>
+ <b>pcre2_compile_8()</b>
+ <b>pcre2_compile_16()</b>
+ <b>pcre2_compile_32()</b>
+</pre>
+There are also three different sets of data types:
+<pre>
+ <b>PCRE2_UCHAR8, PCRE2_UCHAR16, PCRE2_UCHAR32</b>
+ <b>PCRE2_SPTR8, PCRE2_SPTR16, PCRE2_SPTR32</b>
+</pre>
+The UCHAR types define unsigned code units of the appropriate widths. For
+example, PCRE2_UCHAR16 is usually defined as `uint16_t'. The SPTR types are
+constant pointers to the equivalent UCHAR types, that is, they are pointers to
+vectors of unsigned code units.
+</P>
+<P>
+Many applications use only one code unit width. For their convenience, macros
+are defined whose names are the generic forms such as <b>pcre2_compile()</b> and
+PCRE2_SPTR. These macros use the value of the macro PCRE2_CODE_UNIT_WIDTH to
+generate the appropriate width-specific function and macro names.
+PCRE2_CODE_UNIT_WIDTH is not defined by default. An application must define it
+to be 8, 16, or 32 before including <b>pcre2.h</b> in order to make use of the
+generic names.
+</P>
+<P>
+Applications that use more than one code unit width can be linked with more
+than one PCRE2 library, but must define PCRE2_CODE_UNIT_WIDTH to be 0 before
+including <b>pcre2.h</b>, and then use the real function names. Any code that is
+to be included in an environment where the value of PCRE2_CODE_UNIT_WIDTH is
+unknown should also use the real function names. (Unfortunately, it is not
+possible in C code to save and restore the value of a macro.)
+</P>
+<P>
+If PCRE2_CODE_UNIT_WIDTH is not defined before including <b>pcre2.h</b>, a
+compiler error occurs.
+</P>
+<P>
+When using multiple libraries in an application, you must take care when
+processing any particular pattern to use only functions from a single library.
+For example, if you want to run a match using a pattern that was compiled with
+<b>pcre2_compile_16()</b>, you must do so with <b>pcre2_match_16()</b>, not
+<b>pcre2_match_8()</b>.
+</P>
+<P>
+In the function summaries above, and in the rest of this document and other
+PCRE2 documents, functions and data types are described using their generic
+names, without the 8, 16, or 32 suffix.
+</P>
+<br><a name="SEC12" href="#TOC1">PCRE2 API OVERVIEW</a><br>
+<P>
+PCRE2 has its own native API, which is described in this document. There are
+also some wrapper functions for the 8-bit library that correspond to the
+POSIX regular expression API, but they do not give access to all the
+functionality. They are described in the
+<a href="pcre2posix.html"><b>pcre2posix</b></a>
+documentation. Both these APIs define a set of C function calls.
+</P>
+<P>
+The native API C data types, function prototypes, option values, and error
+codes are defined in the header file <b>pcre2.h</b>, which contains definitions
+of PCRE2_MAJOR and PCRE2_MINOR, the major and minor release numbers for the
+library. Applications can use these to include support for different releases
+of PCRE2.
+</P>
+<P>
+In a Windows environment, if you want to statically link an application program
+against a non-dll PCRE2 library, you must define PCRE2_STATIC before including
+<b>pcre2.h</b>.
+</P>
+<P>
+The functions <b>pcre2_compile()</b>, and <b>pcre2_match()</b> are used for
+compiling and matching regular expressions in a Perl-compatible manner. A
+sample program that demonstrates the simplest way of using them is provided in
+the file called <i>pcre2demo.c</i> in the PCRE2 source distribution. A listing
+of this program is given in the
+<a href="pcre2demo.html"><b>pcre2demo</b></a>
+documentation, and the
+<a href="pcre2sample.html"><b>pcre2sample</b></a>
+documentation describes how to compile and run it.
+</P>
+<P>
+Just-in-time compiler support is an optional feature of PCRE2 that can be built
+in appropriate hardware environments. It greatly speeds up the matching
+performance of many patterns. Programs can request that it be used if
+available, by calling <b>pcre2_jit_compile()</b> after a pattern has been
+successfully compiled by <b>pcre2_compile()</b>. This does nothing if JIT
+support is not available.
+</P>
+<P>
+More complicated programs might need to make use of the specialist functions
+<b>pcre2_jit_stack_create()</b>, <b>pcre2_jit_stack_free()</b>, and
+<b>pcre2_jit_stack_assign()</b> in order to control the JIT code's memory usage.
+</P>
+<P>
+JIT matching is automatically used by <b>pcre2_match()</b> if it is available.
+There is also a direct interface for JIT matching, which gives improved
+performance. The JIT-specific functions are discussed in the
+<a href="pcre2jit.html"><b>pcre2jit</b></a>
+documentation.
+</P>
+<P>
+A second matching function, <b>pcre2_dfa_match()</b>, which is not
+Perl-compatible, is also provided. This uses a different algorithm for the
+matching. The alternative algorithm finds all possible matches (at a given
+point in the subject), and scans the subject just once (unless there are
+lookbehind assertions). However, this algorithm does not return captured
+substrings. A description of the two matching algorithms and their advantages
+and disadvantages is given in the
+<a href="pcre2matching.html"><b>pcre2matching</b></a>
+documentation. There is no JIT support for <b>pcre2_dfa_match()</b>.
+</P>
+<P>
+In addition to the main compiling and matching functions, there are convenience
+functions for extracting captured substrings from a subject string that has
+been matched by <b>pcre2_match()</b>. They are:
+<pre>
+ <b>pcre2_substring_copy_byname()</b>
+ <b>pcre2_substring_copy_bynumber()</b>
+ <b>pcre2_substring_get_byname()</b>
+ <b>pcre2_substring_get_bynumber()</b>
+ <b>pcre2_substring_list_get()</b>
+ <b>pcre2_substring_length_byname()</b>
+ <b>pcre2_substring_length_bynumber()</b>
+ <b>pcre2_substring_nametable_scan()</b>
+ <b>pcre2_substring_number_from_name()</b>
+</pre>
+<b>pcre2_substring_free()</b> and <b>pcre2_substring_list_free()</b> are also
+provided, to free the memory used for extracted strings.
+</P>
+<P>
+The function <b>pcre2_substitute()</b> can be called to match a pattern and
+return a copy of the subject string with substitutions for parts that were
+matched.
+</P>
+<P>
+Finally, there are functions for finding out information about a compiled
+pattern (<b>pcre2_pattern_info()</b>) and about the configuration with which
+PCRE2 was built (<b>pcre2_config()</b>).
+</P>
+<br><a name="SEC13" href="#TOC1">STRING LENGTHS AND OFFSETS</a><br>
+<P>
+The PCRE2 API uses string lengths and offsets into strings of code units in
+several places. These values are always of type PCRE2_SIZE, which is an
+unsigned integer type, currently always defined as <i>size_t</i>. The largest
+value that can be stored in such a type (that is ~(PCRE2_SIZE)0) is reserved
+as a special indicator for zero-terminated strings and unset offsets.
+Therefore, the longest string that can be handled is one less than this
+maximum.
+<a name="newlines"></a></P>
+<br><a name="SEC14" href="#TOC1">NEWLINES</a><br>
+<P>
+PCRE2 supports five different conventions for indicating line breaks in
+strings: a single CR (carriage return) character, a single LF (linefeed)
+character, the two-character sequence CRLF, any of the three preceding, or any
+Unicode newline sequence. The Unicode newline sequences are the three just
+mentioned, plus the single characters VT (vertical tab, U+000B), FF (form feed,
+U+000C), NEL (next line, U+0085), LS (line separator, U+2028), and PS
+(paragraph separator, U+2029).
+</P>
+<P>
+Each of the first three conventions is used by at least one operating system as
+its standard newline sequence. When PCRE2 is built, a default can be specified.
+The default default is LF, which is the Unix standard. However, the newline
+convention can be changed by an application when calling <b>pcre2_compile()</b>,
+or it can be specified by special text at the start of the pattern itself; this
+overrides any other settings. See the
+<a href="pcre2pattern.html"><b>pcre2pattern</b></a>
+page for details of the special character sequences.
+</P>
+<P>
+In the PCRE2 documentation the word "newline" is used to mean "the character or
+pair of characters that indicate a line break". The choice of newline
+convention affects the handling of the dot, circumflex, and dollar
+metacharacters, the handling of #-comments in /x mode, and, when CRLF is a
+recognized line ending sequence, the match position advancement for a
+non-anchored pattern. There is more detail about this in the
+<a href="#matchoptions">section on <b>pcre2_match()</b> options</a>
+below.
+</P>
+<P>
+The choice of newline convention does not affect the interpretation of
+the \n or \r escape sequences, nor does it affect what \R matches; this has
+its own separate convention.
+</P>
+<br><a name="SEC15" href="#TOC1">MULTITHREADING</a><br>
+<P>
+In a multithreaded application it is important to keep thread-specific data
+separate from data that can be shared between threads. The PCRE2 library code
+itself is thread-safe: it contains no static or global variables. The API is
+designed to be fairly simple for non-threaded applications while at the same
+time ensuring that multithreaded applications can use it.
+</P>
+<P>
+There are several different blocks of data that are used to pass information
+between the application and the PCRE2 libraries.
+</P>
+<P>
+(1) A pointer to the compiled form of a pattern is returned to the user when
+<b>pcre2_compile()</b> is successful. The data in the compiled pattern is fixed,
+and does not change when the pattern is matched. Therefore, it is thread-safe,
+that is, the same compiled pattern can be used by more than one thread
+simultaneously. An application can compile all its patterns at the start,
+before forking off multiple threads that use them. However, if the just-in-time
+optimization feature is being used, it needs separate memory stack areas for
+each thread. See the
+<a href="pcre2jit.html"><b>pcre2jit</b></a>
+documentation for more details.
+</P>
+<P>
+(2) The next section below introduces the idea of "contexts" in which PCRE2
+functions are called. A context is nothing more than a collection of parameters
+that control the way PCRE2 operates. Grouping a number of parameters together
+in a context is a convenient way of passing them to a PCRE2 function without
+using lots of arguments. The parameters that are stored in contexts are in some
+sense "advanced features" of the API. Many straightforward applications will
+not need to use contexts.
+</P>
+<P>
+In a multithreaded application, if the parameters in a context are values that
+are never changed, the same context can be used by all the threads. However, if
+any thread needs to change any value in a context, it must make its own
+thread-specific copy.
+</P>
+<P>
+(3) The matching functions need a block of memory for working space and for
+storing the results of a match. This includes details of what was matched, as
+well as additional information such as the name of a (*MARK) setting. Each
+thread must provide its own version of this memory.
+</P>
+<br><a name="SEC16" href="#TOC1">PCRE2 CONTEXTS</a><br>
+<P>
+Some PCRE2 functions have a lot of parameters, many of which are used only by
+specialist applications, for example, those that use custom memory management
+or non-standard character tables. To keep function argument lists at a
+reasonable size, and at the same time to keep the API extensible, "uncommon"
+parameters are passed to certain functions in a <b>context</b> instead of
+directly. A context is just a block of memory that holds the parameter values.
+Applications that do not need to adjust any of the context parameters can pass
+NULL when a context pointer is required.
+</P>
+<P>
+There are three different types of context: a general context that is relevant
+for several PCRE2 operations, a compile-time context, and a match-time context.
+</P>
+<br><b>
+The general context
+</b><br>
+<P>
+At present, this context just contains pointers to (and data for) external
+memory management functions that are called from several places in the PCRE2
+library. The context is named `general' rather than specifically `memory'
+because in future other fields may be added. If you do not want to supply your
+own custom memory management functions, you do not need to bother with a
+general context. A general context is created by:
+<b>pcre2_general_context *pcre2_general_context_create(</b>
+<b> void *(*<i>private_malloc</i>)(PCRE2_SIZE, void *),</b>
+<b> void (*<i>private_free</i>)(void *, void *), void *<i>memory_data</i>);</b>
+<br>
+<br>
+The two function pointers specify custom memory management functions, whose
+prototypes are:
+<pre>
+ <b>void *private_malloc(PCRE2_SIZE, void *);</b>
+ <b>void private_free(void *, void *);</b>
+</pre>
+Whenever code in PCRE2 calls these functions, the final argument is the value
+of <i>memory_data</i>. Either of the first two arguments of the creation
+function may be NULL, in which case the system memory management functions
+<i>malloc()</i> and <i>free()</i> are used. (This is not currently useful, as
+there are no other fields in a general context, but in future there might be.)
+The <i>private_malloc()</i> function is used (if supplied) to obtain memory for
+storing the context, and all three values are saved as part of the context.
+</P>
+<P>
+Whenever PCRE2 creates a data block of any kind, the block contains a pointer
+to the <i>free()</i> function that matches the <i>malloc()</i> function that was
+used. When the time comes to free the block, this function is called.
+</P>
+<P>
+A general context can be copied by calling:
+<b>pcre2_general_context *pcre2_general_context_copy(</b>
+<b> pcre2_general_context *<i>gcontext</i>);</b>
+<br>
+<br>
+The memory used for a general context should be freed by calling:
+<b>void pcre2_general_context_free(pcre2_general_context *<i>gcontext</i>);</b>
+<a name="compilecontext"></a></P>
+<br><b>
+The compile context
+</b><br>
+<P>
+A compile context is required if you want to change the default values of any
+of the following compile-time parameters:
+<pre>
+ What \R matches (Unicode newlines or CR, LF, CRLF only)
+ PCRE2's character tables
+ The newline character sequence
+ The compile time nested parentheses limit
+ The maximum length of the pattern string
+ An external function for stack checking
+</pre>
+A compile context is also required if you are using custom memory management.
+If none of these apply, just pass NULL as the context argument of
+<i>pcre2_compile()</i>.
+</P>
+<P>

+<b>int pcre2_set_bsr(pcre2_compile_context *<i>ccontext</i>,</b>

+<br>
+<br>
+This parameter ajusts the limit, set when PCRE2 is built (default 250), on the

+The <i>offset_limit</i> parameter limits how far an unanchored search can

+<b>pcre2_match()</b> and <b>pcre2_dfa_match()</b> functions return
+PCRE2_ERROR_NOMATCH if a match with a starting point before or at the given
+offset is not found. For example, if the pattern /abc/ is matched against

+A match can never be found if the <i>startoffset</i> argument of
+<b>pcre2_match()</b> or <b>pcre2_dfa_match()</b> is greater than the offset

+<P>
+When using this facility, you must set PCRE2_USE_OFFSET_LIMIT when calling

+</P>
+<P>
+The offset limit facility can be used to track progress when searching large

+In other words, whichever limit comes first is used.
+<b>int pcre2_set_match_limit(pcre2_match_context *<i>mcontext</i>,</b>

+<br>
+The <i>match_limit</i> parameter provides a means of preventing PCRE2 from using
+up too many resources when processing patterns that are not going to match, but
+which have a very large number of possibilities in their search trees. The
+classic example is a pattern that uses nested unlimited repeats.
+</P>
+<P>
+Internally, <b>pcre2_match()</b> uses a function called <b>match()</b>, which it
+calls repeatedly (sometimes recursively). The limit set by <i>match_limit</i> is
+imposed on the number of times this function is called during a match, which
+has the effect of limiting the amount of backtracking that can take place. For
+patterns that are not anchored, the count restarts from zero for each position
+in the subject string. This limit is not relevant to <b>pcre2_dfa_match()</b>,
+which ignores it.
+</P>
+<P>
+When <b>pcre2_match()</b> is called with a pattern that was successfully
+processed by <b>pcre2_jit_compile()</b>, the way in which matching is executed
+is entirely different. However, there is still the possibility of runaway
+matching that goes on for a very long time, and so the <i>match_limit</i> value
+is also used in this case (but in a different way) to limit how long the
+matching can continue.
+</P>
+<P>
+The default value for the limit can be set when PCRE2 is built; the default
+default is 10 million, which handles all but the most extreme cases. If the
+limit is exceeded, <b>pcre2_match()</b> returns PCRE2_ERROR_MATCHLIMIT. A value
+for the match limit may also be supplied by an item at the start of a pattern
+of the form
+<pre>
+ (*LIMIT_MATCH=ddd)
+</pre>
+where ddd is a decimal number. However, such a setting is ignored unless ddd is
+less than the limit set by the caller of <b>pcre2_match()</b> or, if no such

+<br>
+<br>
+The <i>recursion_limit</i> parameter is similar to <i>match_limit</i>, but
+instead of limiting the total number of times that <b>match()</b> is called, it
+limits the depth of recursion. The recursion depth is a smaller number than the
+total number of calls, because not all calls to <b>match()</b> are recursive.
+This limit is of use only if it is set smaller than <i>match_limit</i>.
+</P>
+<P>
+Limiting the recursion depth limits the amount of system stack that can be
+used, or, when PCRE2 has been compiled to use memory on the heap instead of the

+The default value for <i>recursion_limit</i> can be set when PCRE2 is built; the

+</pre>
+The <i>where</i> argument should point to a buffer that is at least 48 code

+for the terminating zero.
+<pre>
+ PCRE2_CONFIG_LINKSIZE
+</pre>
+The output is a uint32_t integer that contains the number of bytes used for
+internal linkage in compiled regular expressions. When PCRE2 is configured, the
+value can be set to 2, 3, or 4, with the default being 2. This is the value
+that is returned by <b>pcre2_config()</b>. However, when the 16-bit library is

+</P>
+<P>
+The default value of 2 for the 8-bit and 16-bit libraries is sufficient for all

+The output is a uint32_t integer that is set to one if internal recursion when

+contains the compiled pattern and related data. The caller must free the memory
+by calling <b>pcre2_code_free()</b> when it is no longer needed.
+</P>
+<P>
+NOTE: When one of the matching functions is called, pointers to the compiled
+pattern and the subject string are set in the match data block so that they can
+be referenced by the extraction functions. After running a match, you must not
+free a compiled pattern (or a subject string) until after all operations on the
+<a href="#matchdatablock">match data block</a>
+have taken place.
+</P>
+<P>
+If the compile context argument <i>ccontext</i> is NULL, memory for the compiled
+pattern is obtained by calling <b>malloc()</b>. Otherwise, it is obtained from
+the same memory function that was used for the compile context.
+</P>
+<P>
+The <i>options</i> argument contains various bit settings that affect the
+compilation. It should be zero if no options are required. The available
+options are described below. Some of them (in particular, those that are
+compatible with Perl, but some others as well) can also be set and unset from
+within the pattern (see the detailed description in the
+<a href="pcre2pattern.html"><b>pcre2pattern</b></a>
+documentation).
+</P>
+<P>
+For those options that can be different in different parts of the pattern, the

+<P>
+Other, less frequently required compile-time parameters (for example, the

+If <i>errorcode</i> or <i>erroroffset</i> is NULL, <b>pcre2_compile()</b> returns

+ PCRE2_ZERO_TERMINATED, /* the pattern is zero-terminated */
+ 0, /* default options */
+ &errorcode, /* for error code */
+ &erroffset, /* for error offset */
+ NULL); /* no compile context */
+</pre>
+The following names for option bits are defined in the <b>pcre2.h</b> header
+file:
+<pre>
+ PCRE2_ANCHORED
+</pre>
+If this bit is set, the pattern is forced to be "anchored", that is, it is
+constrained to match only at the first matching point in the string that is
+being searched (the "subject string"). This effect can also be achieved by
+appropriate constructs in the pattern itself, which is the only way to do it in
+Perl.
+<pre>
+ PCRE2_ALLOW_EMPTY_CLASS
+</pre>
+By default, for compatibility with Perl, a closing square bracket that
+immediately follows an opening one is treated as a data character for the
+class. When PCRE2_ALLOW_EMPTY_CLASS is set, it terminates the class, which
+therefore contains no characters and so can never match.
+<pre>
+ PCRE2_ALT_BSUX
+</pre>
+This option request alternative handling of three escape sequences, which
+makes PCRE2's behaviour more like ECMAscript (aka JavaScript). When it is set:
+</P>
+<P>
+(1) \U matches an upper case "U" character; by default \U causes a compile
+time error (Perl uses \U to upper case subsequent characters).
+</P>
+<P>
+(2) \u matches a lower case "u" character unless it is followed by four
+hexadecimal digits, in which case the hexadecimal number defines the code point
+to match. By default, \u causes a compile time error (Perl uses it to upper
+case the following character).
+</P>
+<P>
+(3) \x matches a lower case "x" character unless it is followed by two
+hexadecimal digits, in which case the hexadecimal number defines the code point
+to match. By default, as in Perl, a hexadecimal number is always expected after
+\x, but it may have zero, one, or two digits (so, for example, \xz matches a
+binary zero character followed by z).
+<pre>
+ PCRE2_ALT_CIRCUMFLEX
+</pre>
+In multiline mode (when PCRE2_MULTILINE is set), the circumflex metacharacter
+matches at the start of the subject (unless PCRE2_NOTBOL is set), and also
+after any internal newline. However, it does not match after a newline at the
+end of the subject, for compatibility with Perl. If you want a multiline
+circumflex also to match after a terminating newline, you must set
+PCRE2_ALT_CIRCUMFLEX.
+<pre>
+ PCRE2_ALT_VERBNAMES
+</pre>
+By default, for compatibility with Perl, the name in any verb sequence such as
+(*MARK:NAME) is any sequence of characters that does not include a closing
+parenthesis. The name is not processed in any way, and it is not possible to
+include a closing parenthesis in the name. However, if the PCRE2_ALT_VERBNAMES
+option is set, normal backslash processing is applied to verb names and only an
+unescaped closing parenthesis terminates the name. A closing parenthesis can be
+included in a name either as \) or between \Q and \E. If the PCRE2_EXTENDED
+option is set, unescaped whitespace in verb names is skipped and #-comments are
+recognized, exactly as in the rest of the pattern.
+<pre>
+ PCRE2_AUTO_CALLOUT
+</pre>
+If this bit is set, <b>pcre2_compile()</b> automatically inserts callout items,
+all with number 255, before each pattern item. For discussion of the callout
+facility, see the
+<a href="pcre2callout.html"><b>pcre2callout</b></a>
+documentation.
+<pre>
+ PCRE2_CASELESS
+</pre>
+If this bit is set, letters in the pattern match both upper and lower case
+letters in the subject. It is equivalent to Perl's /i option, and it can be
+changed within a pattern by a (?i) option setting.
+<pre>
+ PCRE2_DOLLAR_ENDONLY
+</pre>
+If this bit is set, a dollar metacharacter in the pattern matches only at the
+end of the subject string. Without this option, a dollar also matches
+immediately before a newline at the end of the string (but not before any other
+newlines). The PCRE2_DOLLAR_ENDONLY option is ignored if PCRE2_MULTILINE is
+set. There is no equivalent to this option in Perl, and no way to set it within
+a pattern.
+<pre>
+ PCRE2_DOTALL
+</pre>
+If this bit is set, a dot metacharacter in the pattern matches any character,
+including one that indicates a newline. However, it only ever matches one
+character, even if newlines are coded as CRLF. Without this option, a dot does
+not match when the current position in the subject is at a newline. This option
+is equivalent to Perl's /s option, and it can be changed within a pattern by a
+(?s) option setting. A negative class such as [^a] always matches newline
+characters, independent of the setting of this option.
+<pre>
+ PCRE2_DUPNAMES
+</pre>
+If this bit is set, names used to identify capturing subpatterns need not be
+unique. This can be helpful for certain types of pattern when it is known that
+only one instance of the named subpattern can ever be matched. There are more
+details of named subpatterns below; see also the
+<a href="pcre2pattern.html"><b>pcre2pattern</b></a>
+documentation.
+<pre>
+ PCRE2_EXTENDED
+</pre>
+If this bit is set, most white space characters in the pattern are totally
+ignored except when escaped or inside a character class. However, white space
+is not allowed within sequences such as (?> that introduce various
+parenthesized subpatterns, nor within numerical quantifiers such as {1,3}.
+Ignorable white space is permitted between an item and a following quantifier
+and between a quantifier and a following + that indicates possessiveness.
+</P>
+<P>
+PCRE2_EXTENDED also causes characters between an unescaped # outside a
+character class and the next newline, inclusive, to be ignored, which makes it
+possible to include comments inside complicated patterns. Note that the end of
+this type of comment is a literal newline sequence in the pattern; escape
+sequences that happen to represent a newline do not count. PCRE2_EXTENDED is
+equivalent to Perl's /x option, and it can be changed within a pattern by a
+(?x) option setting.
+</P>
+<P>
+Which characters are interpreted as newlines can be specified by a setting in
+the compile context that is passed to <b>pcre2_compile()</b> or by a special
+sequence at the start of the pattern, as described in the section entitled
+<a href="pcre2pattern.html#newlines">"Newline conventions"</a>
+in the <b>pcre2pattern</b> documentation. A default is defined when PCRE2 is
+built.
+<pre>
+ PCRE2_FIRSTLINE
+</pre>
+If this option is set, an unanchored pattern is required to match before or at
+the first newline in the subject string, though the matched text may continue
+over the newline. See also PCRE2_USE_OFFSET_LIMIT, which provides a more
+general limiting facility. If PCRE2_FIRSTLINE is set with an offset limit, a
+match must occur in the first line and also within the offset limit. In other
+words, whichever limit comes first is used.
+<pre>
+ PCRE2_MATCH_UNSET_BACKREF
+</pre>
+If this option is set, a back reference to an unset subpattern group matches an
+empty string (by default this causes the current matching alternative to fail).
+A pattern such as (\1)(a) succeeds when this option is set (assuming it can
+find an "a" in the subject), whereas it fails by default, for Perl
+compatibility. Setting this option makes PCRE2 behave more like ECMAscript (aka
+JavaScript).
+<pre>
+ PCRE2_MULTILINE
+</pre>
+By default, for the purposes of matching "start of line" and "end of line",
+PCRE2 treats the subject string as consisting of a single line of characters,
+even if it actually contains newlines. The "start of line" metacharacter (^)
+matches only at the start of the string, and the "end of line" metacharacter
+($) matches only at the end of the string, or before a terminating newline
+(except when PCRE2_DOLLAR_ENDONLY is set). Note, however, that unless
+PCRE2_DOTALL is set, the "any character" metacharacter (.) does not match at a
+newline. This behaviour (for ^, $, and dot) is the same as Perl.
+</P>
+<P>
+When PCRE2_MULTILINE it is set, the "start of line" and "end of line"
+constructs match immediately following or immediately before internal newlines
+in the subject string, respectively, as well as at the very start and end. This
+is equivalent to Perl's /m option, and it can be changed within a pattern by a
+(?m) option setting. Note that the "start of line" metacharacter does not match
+after a newline at the end of the subject, for compatibility with Perl.
+However, you can change this by setting the PCRE2_ALT_CIRCUMFLEX option. If
+there are no newlines in a subject string, or no occurrences of ^ or $ in a
+pattern, setting PCRE2_MULTILINE has no effect.
+<pre>
+ PCRE2_NEVER_BACKSLASH_C
+</pre>
+This option locks out the use of \C in the pattern that is being compiled.
+This escape can cause unpredictable behaviour in UTF-8 or UTF-16 modes, because
+it may leave the current matching point in the middle of a multi-code-unit
+character. This option may be useful in applications that process patterns from
+external sources. Note that there is also a build-time option that permanently
+locks out the use of \C.
+<pre>
+ PCRE2_NEVER_UCP
+</pre>
+This option locks out the use of Unicode properties for handling \B, \b, \D,
+\d, \S, \s, \W, \w, and some of the POSIX character classes, as described
+for the PCRE2_UCP option below. In particular, it prevents the creator of the
+pattern from enabling this facility by starting the pattern with (*UCP). This
+option may be useful in applications that process patterns from external
+sources. The option combination PCRE_UCP and PCRE_NEVER_UCP causes an error.
+<pre>
+ PCRE2_NEVER_UTF
+</pre>
+This option locks out interpretation of the pattern as UTF-8, UTF-16, or
+UTF-32, depending on which library is in use. In particular, it prevents the
+creator of the pattern from switching to UTF interpretation by starting the
+pattern with (*UTF). This option may be useful in applications that process
+patterns from external sources. The combination of PCRE2_UTF and
+PCRE2_NEVER_UTF causes an error.
+<pre>
+ PCRE2_NO_AUTO_CAPTURE
+</pre>
+If this option is set, it disables the use of numbered capturing parentheses in
+the pattern. Any opening parenthesis that is not followed by ? behaves as if it
+were followed by ?: but named parentheses can still be used for capturing (and
+they acquire numbers in the usual way). There is no equivalent of this option
+in Perl.
+<pre>
+ PCRE2_NO_AUTO_POSSESS
+</pre>
+If this option is set, it disables "auto-possessification", which is an
+optimization that, for example, turns a+b into a++b in order to avoid
+backtracks into a+ that can never be successful. However, if callouts are in
+use, auto-possessification means that some callouts are never taken. You can
+set this option if you want the matching functions to do a full unoptimized
+search and run all the callouts, but it is mainly provided for testing
+purposes.
+<pre>
+ PCRE2_NO_DOTSTAR_ANCHOR
+</pre>
+If this option is set, it disables an optimization that is applied when .* is
+the first significant item in a top-level branch of a pattern, and all the
+other branches also start with .* or with \A or \G or ^. The optimization is
+automatically disabled for .* if it is inside an atomic group or a capturing
+group that is the subject of a back reference, or if the pattern contains
+(*PRUNE) or (*SKIP). When the optimization is not disabled, such a pattern is
+automatically anchored if PCRE2_DOTALL is set for all the .* items and
+PCRE2_MULTILINE is not set for any ^ items. Otherwise, the fact that any match
+must start either at the start of the subject or following a newline is
+remembered. Like other optimizations, this can cause callouts to be skipped.
+<pre>
+ PCRE2_NO_START_OPTIMIZE
+</pre>
+This is an option whose main effect is at matching time. It does not change
+what <b>pcre2_compile()</b> generates, but it does affect the output of the JIT
+compiler.
+</P>
+<P>
+There are a number of optimizations that may occur at the start of a match, in
+order to speed up the process. For example, if it is known that an unanchored
+match must start with a specific character, the matching code searches the
+subject for that character, and fails immediately if it cannot find it, without
+actually running the main matching function. This means that a special item
+such as (*COMMIT) at the start of a pattern is not considered until after a
+suitable starting point for the match has been found. Also, when callouts or
+(*MARK) items are in use, these "start-up" optimizations can cause them to be
+skipped if the pattern is never actually used. The start-up optimizations are
+in effect a pre-scan of the subject that takes place before the pattern is run.
+</P>
+<P>
+The PCRE2_NO_START_OPTIMIZE option disables the start-up optimizations,
+possibly causing performance to suffer, but ensuring that in cases where the
+result is "no match", the callouts do occur, and that items such as (*COMMIT)
+and (*MARK) are considered at every possible starting position in the subject
+string.
+</P>
+<P>
+Setting PCRE2_NO_START_OPTIMIZE may change the outcome of a matching operation.
+Consider the pattern
+<pre>
+ (*COMMIT)ABC
+</pre>
+When this is compiled, PCRE2 records the fact that a match must start with the
+character "A". Suppose the subject string is "DEFABC". The start-up
+optimization scans along the subject, finds "A" and runs the first match
+attempt from there. The (*COMMIT) item means that the pattern must match the
+current starting position, which in this case, it does. However, if the same
+match is run with PCRE2_NO_START_OPTIMIZE set, the initial scan along the
+subject string does not happen. The first match attempt is run starting from
+"D" and when this fails, (*COMMIT) prevents any further matches being tried, so
+the overall result is "no match". There are also other start-up optimizations.
+For example, a minimum length for the subject may be recorded. Consider the
+pattern
+<pre>
+ (*MARK:A)(X|Y)
+</pre>
+The minimum length for a match is one character. If the subject is "ABC", there
+will be attempts to match "ABC", "BC", and "C". An attempt to match an empty
+string at the end of the subject does not take place, because PCRE2 knows that
+the subject is now too short, and so the (*MARK) is never encountered. In this
+case, the optimization does not affect the overall match result, which is still
+"no match", but it does affect the auxiliary information that is returned.
+<pre>
+ PCRE2_NO_UTF_CHECK
+</pre>
+When PCRE2_UTF is set, the validity of the pattern as a UTF string is
+automatically checked. There are discussions about the validity of
+<a href="pcre2unicode.html#utf8strings">UTF-8 strings,</a>
+<a href="pcre2unicode.html#utf16strings">UTF-16 strings,</a>
+and
+<a href="pcre2unicode.html#utf32strings">UTF-32 strings</a>
+in the
+<a href="pcre2unicode.html"><b>pcre2unicode</b></a>
+document.
+If an invalid UTF sequence is found, <b>pcre2_compile()</b> returns a negative
+error code.
+</P>
+<P>
+If you know that your pattern is valid, and you want to skip this check for
+performance reasons, you can set the PCRE2_NO_UTF_CHECK option. When it is set,
+the effect of passing an invalid UTF string as a pattern is undefined. It may
+cause your program to crash or loop. Note that this option can also be passed
+to <b>pcre2_match()</b> and <b>pcre_dfa_match()</b>, to suppress validity
+checking of the subject string.
+<pre>
+ PCRE2_UCP
+</pre>
+This option changes the way PCRE2 processes \B, \b, \D, \d, \S, \s, \W,
+\w, and some of the POSIX character classes. By default, only ASCII characters
+are recognized, but if PCRE2_UCP is set, Unicode properties are used instead to
+classify characters. More details are given in the section on
+<a href="pcre2pattern.html#genericchartypes">generic character types</a>
+in the
+<a href="pcre2pattern.html"><b>pcre2pattern</b></a>
+page. If you set PCRE2_UCP, matching one of the items it affects takes much
+longer. The option is available only if PCRE2 has been compiled with Unicode
+support.
+<pre>
+ PCRE2_UNGREEDY
+</pre>
+This option inverts the "greediness" of the quantifiers so that they are not
+greedy by default, but become greedy if followed by "?". It is not compatible
+with Perl. It can also be set by a (?U) option setting within the pattern.
+<pre>
+ PCRE2_USE_OFFSET_LIMIT
+</pre>
+This option must be set for <b>pcre2_compile()</b> if
+<b>pcre2_set_offset_limit()</b> is going to be used to set a non-default offset
+limit in a match context for matches that use this pattern. An error is
+generated if an offset limit is set without this option. For more details, see
+the description of <b>pcre2_set_offset_limit()</b> in the
+<a href="#matchcontext">section</a>
+that describes match contexts. See also the PCRE2_FIRSTLINE
+option above.
+<pre>
+ PCRE2_UTF
+</pre>
+This option causes PCRE2 to regard both the pattern and the subject strings
+that are subsequently processed as strings of UTF characters instead of
+single-code-unit strings. It is available when PCRE2 is built to include
+Unicode support (which is the default). If Unicode support is not available,
+the use of this option provokes an error. Details of how this option changes
+the behaviour of PCRE2 are given in the
+<a href="pcre2unicode.html"><b>pcre2unicode</b></a>
+page.
+</P>
+<br><a name="SEC19" href="#TOC1">COMPILATION ERROR CODES</a><br>

+<br><a name="SEC21" href="#TOC1">LOCALE SUPPORT</a><br>
+<P>
+PCRE2 handles caseless matching, and determines whether characters are letters,
+digits, or whatever, by reference to a set of tables, indexed by character code
+point. This applies only to characters whose code points are less than 256. By
+default, higher-valued code points never match escapes such as \w or \d.
+However, if PCRE2 is built with UTF support, all characters can be tested with
+\p and \P, or, alternatively, the PCRE2_UCP option can be set when a pattern
+is compiled; this causes \w and friends to use Unicode property support
+instead of the built-in tables.
+</P>
+<P>
+The use of locales with Unicode is discouraged. If you are handling characters
+with code points greater than 128, you should either use Unicode support, or
+use locales, but not try to mix the two.
+</P>
+<P>
+PCRE2 contains an internal set of character tables that are used by default.
+These are sufficient for many applications. Normally, the internal tables
+recognize only ASCII characters. However, when PCRE2 is built, it is possible
+to cause the internal tables to be rebuilt in the default "C" locale of the
+local system, which may cause them to be different.
+</P>
+<P>
+The internal tables can be overridden by tables supplied by the application
+that calls PCRE2. These may be created in a different locale from the default.
+As more and more applications change to using Unicode, the need for this locale
+support is expected to die away.
+</P>
+<P>
+External tables are built by calling the <b>pcre2_maketables()</b> function, in
+the relevant locale. The result can be passed to <b>pcre2_compile()</b> as often
+as necessary, by creating a compile context and calling
+<b>pcre2_set_character_tables()</b> to set the tables pointer therein. For
+example, to build and use tables that are appropriate for the French locale
+(where accented characters with values greater than 128 are treated as
+letters), the following code could be used:
+<pre>
+ setlocale(LC_CTYPE, "fr_FR");
+ tables = pcre2_maketables(NULL);
+ ccontext = pcre2_compile_context_create(NULL);
+ pcre2_set_character_tables(ccontext, tables);
+ re = pcre2_compile(..., ccontext);
+</pre>
+The locale name "fr_FR" is used on Linux and other Unix-like systems; if you
+are using Windows, the name for the French locale is "french". It is the
+caller's responsibility to ensure that the memory containing the tables remains
+available for as long as it is needed.
+</P>
+<P>
+The pointer that is passed (via the compile context) to <b>pcre2_compile()</b>
+is saved with the compiled pattern, and the same tables are used by
+<b>pcre2_match()</b> and <b>pcre_dfa_match()</b>. Thus, for any single pattern,
+compilation, and matching all happen in the same locale, but different patterns
+can be processed in different locales.

+</P>
+<P>
+The <b>pcre2_pattern_info()</b> function returns general information about a
+compiled pattern. For information about callouts, see the
+<a href="pcre2pattern.html#infoaboutcallouts">next section.</a>
+The first argument for <b>pcre2_pattern_info()</b> is a pointer to the compiled
+pattern. The second argument specifies which piece of information is required,
+and the third argument is a pointer to a variable to receive the data. If the
+third argument is NULL, the first argument is ignored, and the function returns
+the size in bytes of the variable that is required for the information
+requested. Otherwise, The yield of the function is zero for success, or one of
+the following negative numbers:
+<pre>
+ PCRE2_ERROR_NULL the argument <i>code</i> was NULL
+ PCRE2_ERROR_BADMAGIC the "magic number" was not found
+ PCRE2_ERROR_BADOPTION the value of <i>what</i> was invalid
+ PCRE2_ERROR_UNSET the requested field is not set
+</pre>
+The "magic number" is placed at the start of each compiled pattern as an simple
+check against passing an arbitrary memory pointer. Here is a typical call of
+<b>pcre2_pattern_info()</b>, to obtain the length of the compiled pattern:
+<pre>
+ int rc;
+ size_t length;
+ rc = pcre2_pattern_info(
+ re, /* result of pcre2_compile() */
+ PCRE2_INFO_SIZE, /* what is required */
+ &length); /* where to put the data */
+</pre>
+The possible values for the second argument are defined in <b>pcre2.h</b>, and
+are as follows:
+<pre>
+ PCRE2_INFO_ALLOPTIONS
+ PCRE2_INFO_ARGOPTIONS
+</pre>
+Return a copy of the pattern's options. The third argument should point to a
+<b>uint32_t</b> variable. PCRE2_INFO_ARGOPTIONS returns exactly the options that
+were passed to <b>pcre2_compile()</b>, whereas PCRE2_INFO_ALLOPTIONS returns
+the compile options as modified by any top-level option settings such as (*UTF)
+at the start of the pattern itself. For example, if the pattern /(*UTF)abc/ is
+compiled with the PCRE2_EXTENDED option, the result is PCRE2_EXTENDED and
+PCRE2_UTF.
+</P>
+<P>
+A pattern compiled without PCRE2_ANCHORED is automatically anchored by PCRE2 if
+the first significant item in every top-level branch is one of the following:
+<pre>
+ ^ unless PCRE2_MULTILINE is set
+ \A always
+ \G always
+ .* sometimes - see below
+</pre>
+When .* is the first significant item, anchoring is possible only when all the
+following are true:
+<pre>
+ .* is not in an atomic group
+ .* is not in a capturing group that is the subject of a back reference
+ PCRE2_DOTALL is in force for .*
+ Neither (*PRUNE) nor (*SKIP) appears in the pattern.
+ PCRE2_NO_DOTSTAR_ANCHOR is not set.
+</pre>
+For patterns that are auto-anchored, the PCRE2_ANCHORED bit is set in the
+options returned for PCRE2_INFO_ALLOPTIONS.
+<pre>
+ PCRE2_INFO_BACKREFMAX
+</pre>
+Return the number of the highest back reference in the pattern. The third
+argument should point to an <b>uint32_t</b> variable. Named subpatterns acquire
+numbers as well as names, and these count towards the highest back reference.
+Back references such as \4 or \g{12} match the captured characters of the
+given group, but in addition, the check that a capturing group is set in a
+conditional subpattern such as (?(3)a|b) is also a back reference. Zero is
+returned if there are no back references.
+<pre>
+ PCRE2_INFO_BSR
+</pre>
+The output is a uint32_t whose value indicates what character sequences the \R
+escape sequence matches. A value of PCRE2_BSR_UNICODE means that \R matches
+any Unicode line ending sequence; a value of PCRE2_BSR_ANYCRLF means that \R
+matches only CR, LF, or CRLF.
+<pre>
+ PCRE2_INFO_CAPTURECOUNT
+</pre>
+Return the highest capturing subpattern number in the pattern. In patterns
+where (?| is not used, this is also the total number of capturing subpatterns.
+The third argument should point to an <b>uint32_t</b> variable.
+<pre>
+ PCRE2_INFO_FIRSTBITMAP
+</pre>
+In the absence of a single first code unit for a non-anchored pattern,
+<b>pcre2_compile()</b> may construct a 256-bit table that defines a fixed set of
+values for the first code unit in any match. For example, a pattern that starts
+with [abc] results in a table with three bits set. When code unit values
+greater than 255 are supported, the flag bit for 255 means "any code unit of
+value 255 or above". If such a table was constructed, a pointer to it is
+returned. Otherwise NULL is returned. The third argument should point to an
+<b>const uint8_t *</b> variable.
+<pre>
+ PCRE2_INFO_FIRSTCODETYPE
+</pre>
+Return information about the first code unit of any matched string, for a
+non-anchored pattern. The third argument should point to an <b>uint32_t</b>
+variable. If there is a fixed first value, for example, the letter "c" from a
+pattern such as (cat|cow|coyote), 1 is returned, and the character value can be
+retrieved using PCRE2_INFO_FIRSTCODEUNIT. If there is no fixed first value, but
+it is known that a match can occur only at the start of the subject or
+following a newline in the subject, 2 is returned. Otherwise, and for anchored
+patterns, 0 is returned.
+<pre>
+ PCRE2_INFO_FIRSTCODEUNIT
+</pre>
+Return the value of the first code unit of any matched string in the situation
+where PCRE2_INFO_FIRSTCODETYPE returns 1; otherwise return 0. The third
+argument should point to an <b>uint32_t</b> variable. In the 8-bit library, the
+value is always less than 256. In the 16-bit library the value can be up to
+0xffff. In the 32-bit library in UTF-32 mode the value can be up to 0x10ffff,
+and up to 0xffffffff when not using UTF-32 mode.
+<pre>
+ PCRE2_INFO_HASBACKSLASHC
+</pre>
+Return 1 if the pattern contains any instances of \C, otherwise 0. The third
+argument should point to an <b>uint32_t</b> variable.
+<pre>
+ PCRE2_INFO_HASCRORLF
+</pre>
+Return 1 if the pattern contains any explicit matches for CR or LF characters,
+otherwise 0. The third argument should point to an <b>uint32_t</b> variable. An
+explicit match is either a literal CR or LF character, or \r or \n.
+<pre>
+ PCRE2_INFO_JCHANGED
+</pre>
+Return 1 if the (?J) or (?-J) option setting is used in the pattern, otherwise
+0. The third argument should point to an <b>uint32_t</b> variable. (?J) and
+(?-J) set and unset the local PCRE2_DUPNAMES option, respectively.
+<pre>
+ PCRE2_INFO_JITSIZE
+</pre>
+If the compiled pattern was successfully processed by
+<b>pcre2_jit_compile()</b>, return the size of the JIT compiled code, otherwise
+return zero. The third argument should point to a <b>size_t</b> variable.
+<pre>
+ PCRE2_INFO_LASTCODETYPE
+</pre>
+Returns 1 if there is a rightmost literal code unit that must exist in any
+matched string, other than at its start. The third argument should point to an
+<b>uint32_t</b> variable. If there is no such value, 0 is returned. When 1 is
+returned, the code unit value itself can be retrieved using
+PCRE2_INFO_LASTCODEUNIT. For anchored patterns, a last literal value is
+recorded only if it follows something of variable length. For example, for the
+pattern /^a\d+z\d+/ the returned value is 1 (with "z" returned from
+PCRE2_INFO_LASTCODEUNIT), but for /^a\dz\d/ the returned value is 0.
+<pre>
+ PCRE2_INFO_LASTCODEUNIT
+</pre>
+Return the value of the rightmost literal data unit that must exist in any
+matched string, other than at its start, if such a value has been recorded. The
+third argument should point to an <b>uint32_t</b> variable. If there is no such
+value, 0 is returned.
+<pre>
+ PCRE2_INFO_MATCHEMPTY
+</pre>
+Return 1 if the pattern might match an empty string, otherwise 0. The third
+argument should point to an <b>uint32_t</b> variable. When a pattern contains

+in such cases.
+<pre>
+ PCRE2_INFO_MATCHLIMIT
+</pre>
+If the pattern set a match limit by including an item of the form
+(*LIMIT_MATCH=nnnn) at the start, the value is returned. The third argument
+should point to an unsigned 32-bit integer. If no such value has been set, the
+call to <b>pcre2_pattern_info()</b> returns the error PCRE2_ERROR_UNSET.
+<pre>
+ PCRE2_INFO_MAXLOOKBEHIND
+</pre>
+Return the number of characters (not code units) in the longest lookbehind
+assertion in the pattern. The third argument should point to an unsigned 32-bit
+integer. This information is useful when doing multi-segment matching using the
+partial matching facilities. Note that the simple assertions \b and \B
+require a one-character lookbehind. \A also registers a one-character
+lookbehind, though it does not actually inspect the previous character. This is
+to ensure that at least one character from the old segment is retained when a
+new segment is processed. Otherwise, if there are no lookbehinds in the
+pattern, \A might match incorrectly at the start of a new segment.
+<pre>
+ PCRE2_INFO_MINLENGTH
+</pre>
+If a minimum length for matching subject strings was computed, its value is
+returned. Otherwise the returned value is 0. The value is a number of
+characters, which in UTF mode may be different from the number of code units.
+The third argument should point to an <b>uint32_t</b> variable. The value is a
+lower bound to the length of any matching string. There may not be any strings
+of that length that do actually match, but every string that does match is at
+least that long.
+<pre>
+ PCRE2_INFO_NAMECOUNT
+ PCRE2_INFO_NAMEENTRYSIZE
+ PCRE2_INFO_NAMETABLE
+</pre>
+PCRE2 supports the use of named as well as numbered capturing parentheses. The
+names are just an additional way of identifying the parentheses, which still
+acquire numbers. Several convenience functions such as
+<b>pcre2_substring_get_byname()</b> are provided for extracting captured
+substrings by name. It is also possible to extract the data directly, by first
+converting the name to a number in order to access the correct pointers in the
+output vector (described with <b>pcre2_match()</b> below). To do the conversion,
+you need to use the name-to-number map, which is described by these three
+values.
+</P>
+<P>
+The map consists of a number of fixed-size entries. PCRE2_INFO_NAMECOUNT gives
+the number of entries, and PCRE2_INFO_NAMEENTRYSIZE gives the size of each
+entry in code units; both of these return a <b>uint32_t</b> value. The entry
+size depends on the length of the longest name.
+</P>
+<P>
+PCRE2_INFO_NAMETABLE returns a pointer to the first entry of the table. This is
+a PCRE2_SPTR pointer to a block of code units. In the 8-bit library, the first
+two bytes of each entry are the number of the capturing parenthesis, most
+significant byte first. In the 16-bit library, the pointer points to 16-bit
+code units, the first of which contains the parenthesis number. In the 32-bit
+library, the pointer points to 32-bit code units, the first of which contains
+the parenthesis number. The rest of the entry is the corresponding name, zero
+terminated.
+</P>
+<P>
+The names are in alphabetical order. If (?| is used to create multiple groups
+with the same number, as described in the
+<a href="pcre2pattern.html#dupsubpatternnumber">section on duplicate subpattern numbers</a>
+in the
+<a href="pcre2pattern.html"><b>pcre2pattern</b></a>
+page, the groups may be given the same name, but there is only one entry in the
+table. Different names for groups of the same number are not permitted.
+</P>
+<P>
+Duplicate names for subpatterns with different numbers are permitted, but only
+if PCRE2_DUPNAMES is set. They appear in the table in the order in which they
+were found in the pattern. In the absence of (?| this is the order of
+increasing number; when (?| is used this is not necessarily the case because
+later subpatterns may have lower numbers.
+</P>
+<P>
+As a simple example of the name/number table, consider the following pattern
+after compilation by the 8-bit library (assume PCRE2_EXTENDED is set, so white
+space - including newlines - is ignored):
+<pre>
+ (?<date> (?<year>(\d\d)?\d\d) - (?<month>\d\d) - (?<day>\d\d) )
+</pre>
+There are four named subpatterns, so the table has four entries, and each entry
+in the table is eight bytes long. The table is as follows, with non-printing
+bytes shows in hexadecimal, and undefined bytes shown as ??:
+<pre>
+ 00 01 d a t e 00 ??
+ 00 05 d a y 00 ?? ??
+ 00 04 m o n t h 00
+ 00 02 y e a r 00 ??
+</pre>
+When writing code to extract data from named subpatterns using the
+name-to-number map, remember that the length of the entries is likely to be
+different for each compiled pattern.
+<pre>
+ PCRE2_INFO_NEWLINE
+</pre>
+The output is a <b>uint32_t</b> with one of the following values:
+<pre>
+ PCRE2_NEWLINE_CR Carriage return (CR)
+ PCRE2_NEWLINE_LF Linefeed (LF)
+ PCRE2_NEWLINE_CRLF Carriage return, linefeed (CRLF)
+ PCRE2_NEWLINE_ANY Any Unicode line ending
+ PCRE2_NEWLINE_ANYCRLF Any of CR, LF, or CRLF
+</pre>
+This specifies the default character sequence that will be recognized as
+meaning "newline" while matching.
+<pre>
+ PCRE2_INFO_RECURSIONLIMIT
+</pre>
+If the pattern set a recursion limit by including an item of the form
+(*LIMIT_RECURSION=nnnn) at the start, the value is returned. The third
+argument should point to an unsigned 32-bit integer. If no such value has been
+set, the call to <b>pcre2_pattern_info()</b> returns the error PCRE2_ERROR_UNSET.
+<pre>
+ PCRE2_INFO_SIZE
+</pre>
+Return the size of the compiled pattern in bytes (for all three libraries). The
+third argument should point to a <b>size_t</b> variable. This value includes the
+size of the general data block that precedes the code units of the compiled
+pattern itself. The value that is used when <b>pcre2_compile()</b> is getting
+memory in which to place the compiled pattern may be slightly larger than the
+value returned by this option, because there are cases where the code that
+calculates the size has to over-estimate. Processing a pattern with the JIT
+compiler does not alter the value returned by this option.

+</P>
+<P>
+This function is the main matching facility of the library, and it operates in

+function, which is described
+<a href="#dfamatch">below</a>
+in the section about the <b>pcre2_dfa_match()</b> function.
+</P>
+<P>
+Here is an example of a simple call to <b>pcre2_match()</b>:
+<pre>
+ pcre2_match_data *md = pcre2_match_data_create(4, NULL);
+ int rc = pcre2_match(
+ re, /* result of pcre2_compile() */
+ "some string", /* the subject string */

+above.
+</P>
+<br><b>
+The string to be matched by <b>pcre2_match()</b>
+</b><br>
+<P>
+The subject string is passed to <b>pcre2_match()</b> as a pointer in
+<i>subject</i>, a length in <i>length</i>, and a starting offset in
+<i>startoffset</i>. The length and offset are in code units, not characters.
+That is, they are in bytes for the 8-bit library, 16-bit code units for the
+16-bit library, and 32-bit code units for the 32-bit library, whether or not
+UTF processing is enabled.
+</P>
+<P>
+If <i>startoffset</i> is greater than the length of the subject,
+<b>pcre2_match()</b> returns PCRE2_ERROR_BADOFFSET. When the starting offset is
+zero, the search for a match starts at the beginning of the subject, and this
+is by far the most common case. In UTF-8 or UTF-16 mode, the starting offset
+must point to the start of a character, or to the end of the subject (in UTF-32
+mode, one code unit equals one character, so all offsets are valid). Like the
+pattern string, the subject may contain binary zeroes.
+</P>
+<P>
+A non-zero starting offset is useful when searching for another match in the
+same subject by calling <b>pcre2_match()</b> again after a previous success.
+Setting <i>startoffset</i> differs from passing over a shortened string and
+setting PCRE2_NOTBOL in the case of a pattern that begins with any kind of
+lookbehind. For example, consider the pattern
+<pre>
+ \Biss\B
+</pre>
+which finds occurrences of "iss" in the middle of words. (\B matches only if
+the current position in the subject is not a word boundary.) When applied to
+the string "Mississipi" the first call to <b>pcre2_match()</b> finds the first
+occurrence. If <b>pcre2_match()</b> is called again with just the remainder of
+the subject, namely "issipi", it does not match, because \B is always false at
+the start of the subject, which is deemed to be a word boundary. However, if
+<b>pcre2_match()</b> is passed the entire string again, but with
+<i>startoffset</i> set to 4, it finds the second occurrence of "iss" because it
+is able to look behind the starting point to discover that it is preceded by a
+letter.
+</P>
+<P>
+Finding all the matches in a subject is tricky when the pattern can match an
+empty string. It is possible to emulate Perl's /g behaviour by first trying the
+match again at the same offset, with the PCRE2_NOTEMPTY_ATSTART and
+PCRE2_ANCHORED options, and then if that fails, advancing the starting offset
+and trying an ordinary match again. There is some code that demonstrates how to
+do this in the
+<a href="pcre2demo.html"><b>pcre2demo</b></a>
+sample program. In the most general case, you have to check to see if the
+newline convention recognizes CRLF as a newline, and if so, and the current
+character is CR followed by LF, advance the starting offset by two characters
+instead of one.
+</P>
+<P>
+If a non-zero starting offset is passed when the pattern is anchored, one
+attempt to match at the given offset is made. This can only succeed if the
+pattern does not require the match to be at the start of the subject.

+<br><b>
+Option bits for <b>pcre2_match()</b>
+</b><br>
+<P>
+The unused bits of the <i>options</i> argument for <b>pcre2_match()</b> must be
+zero. The only bits that may be set are PCRE2_ANCHORED, PCRE2_NOTBOL,
+PCRE2_NOTEOL, PCRE2_NOTEMPTY, PCRE2_NOTEMPTY_ATSTART, PCRE2_NO_UTF_CHECK,
+PCRE2_PARTIAL_HARD, and PCRE2_PARTIAL_SOFT. Their action is described below.
+</P>
+<P>
+Setting PCRE2_ANCHORED at match time is not supported by the just-in-time (JIT)
+compiler. If it is set, JIT matching is disabled and the normal interpretive
+code in <b>pcre2_match()</b> is run. The remaining options are supported for JIT
+matching.
+<pre>
+ PCRE2_ANCHORED
+</pre>
+The PCRE2_ANCHORED option limits <b>pcre2_match()</b> to matching at the first
+matching position. If a pattern was compiled with PCRE2_ANCHORED, or turned out
+to be anchored by virtue of its contents, it cannot be made unachored at
+matching time. Note that setting the option at match time disables JIT
+matching.
+<pre>
+ PCRE2_NOTBOL
+</pre>
+This option specifies that first character of the subject string is not the
+beginning of a line, so the circumflex metacharacter should not match before
+it. Setting this without having set PCRE2_MULTILINE at compile time causes
+circumflex never to match. This option affects only the behaviour of the
+circumflex metacharacter. It does not affect \A.
+<pre>
+ PCRE2_NOTEOL
+</pre>
+This option specifies that the end of the subject string is not the end of a
+line, so the dollar metacharacter should not match it nor (except in multiline
+mode) a newline immediately before it. Setting this without having set
+PCRE2_MULTILINE at compile time causes dollar never to match. This option
+affects only the behaviour of the dollar metacharacter. It does not affect \Z
+or \z.
+<pre>
+ PCRE2_NOTEMPTY
+</pre>
+An empty string is not considered to be a valid match if this option is set. If
+there are alternatives in the pattern, they are tried. If all the alternatives
+match the empty string, the entire match fails. For example, if the pattern
+<pre>
+ a?b?
+</pre>
+is applied to a string not beginning with "a" or "b", it matches an empty
+string at the start of the subject. With PCRE2_NOTEMPTY set, this match is not
+valid, so <b>pcre2_match()</b> searches further into the string for occurrences
+of "a" or "b".
+<pre>
+ PCRE2_NOTEMPTY_ATSTART
+</pre>
+This is like PCRE2_NOTEMPTY, except that it locks out an empty string match
+only at the first matching position, that is, at the start of the subject plus
+the starting offset. An empty string match later in the subject is permitted.
+If the pattern is anchored, such a match can occur only if the pattern contains
+\K.
+<pre>
+ PCRE2_NO_UTF_CHECK
+</pre>
+When PCRE2_UTF is set at compile time, the validity of the subject as a UTF
+string is checked by default when <b>pcre2_match()</b> is subsequently called.
+If a non-zero starting offset is given, the check is applied only to that part
+of the subject that could be inspected during matching, and there is a check
+that the starting offset points to the first code unit of a character or to the
+end of the subject. If there are no lookbehind assertions in the pattern, the
+check starts at the starting offset. Otherwise, it starts at the length of the
+longest lookbehind before the starting offset, or at the start of the subject
+if there are not that many characters before the starting offset. Note that the
+sequences \b and \B are one-character lookbehinds.
+</P>
+<P>
+The check is carried out before any other processing takes place, and a
+negative error code is returned if the check fails. There are several UTF error
+codes for each code unit width, corresponding to different problems with the
+code unit sequence. There are discussions about the validity of
+<a href="pcre2unicode.html#utf8strings">UTF-8 strings,</a>
+<a href="pcre2unicode.html#utf16strings">UTF-16 strings,</a>
+and
+<a href="pcre2unicode.html#utf32strings">UTF-32 strings</a>
+in the
+<a href="pcre2unicode.html"><b>pcre2unicode</b></a>
+page.
+</P>
+<P>
+If you know that your subject is valid, and you want to skip these checks for
+performance reasons, you can set the PCRE2_NO_UTF_CHECK option when calling
+<b>pcre2_match()</b>. You might want to do this for the second and subsequent
+calls to <b>pcre2_match()</b> if you are making repeated calls to find all the
+matches in a single subject string.
+</P>
+<P>
+NOTE: When PCRE2_NO_UTF_CHECK is set, the effect of passing an invalid string
+as a subject, or an invalid value of <i>startoffset</i>, is undefined. Your
+program may crash or loop indefinitely.
+<pre>
+ PCRE2_PARTIAL_HARD
+ PCRE2_PARTIAL_SOFT
+</pre>
+These options turn on the partial matching feature. A partial match occurs if
+the end of the subject string is reached successfully, but there are not enough
+subject characters to complete the match. If this happens when
+PCRE2_PARTIAL_SOFT (but not PCRE2_PARTIAL_HARD) is set, matching continues by
+testing any remaining alternatives. Only if no complete match can be found is
+PCRE2_ERROR_PARTIAL returned instead of PCRE2_ERROR_NOMATCH. In other words,
+PCRE2_PARTIAL_SOFT specifies that the caller is prepared to handle a partial
+match, but only if no complete match can be found.
+</P>
+<P>
+If PCRE2_PARTIAL_HARD is set, it overrides PCRE2_PARTIAL_SOFT. In this case, if
+a partial match is found, <b>pcre2_match()</b> immediately returns
+PCRE2_ERROR_PARTIAL, without considering any other alternatives. In other
+words, when PCRE2_PARTIAL_HARD is set, a partial match is considered to be more
+important that an alternative complete match.
+</P>
+<P>
+There is a more detailed discussion of partial and multi-segment matching, with

+documentation.

+<br><a name="SEC27" href="#TOC1">NEWLINE HANDLING WHEN MATCHING</a><br>
+<P>
+When PCRE2 is built, a default newline convention is set; this is usually the
+standard convention for the operating system. The default can be overridden in
+a
+<a href="#compilecontext">compile context</a>
+by calling <b>pcre2_set_newline()</b>. It can also be overridden by starting a
+pattern string with, for example, (*CRLF), as described in the
+<a href="pcre2pattern.html#newlines">section on newline conventions</a>
+in the
+<a href="pcre2pattern.html"><b>pcre2pattern</b></a>
+page. During matching, the newline choice affects the behaviour of the dot,
+circumflex, and dollar metacharacters. It may also alter the way the match
+starting position is advanced after a match failure for an unanchored pattern.
+</P>
+<P>
+When PCRE2_NEWLINE_CRLF, PCRE2_NEWLINE_ANYCRLF, or PCRE2_NEWLINE_ANY is set as
+the newline convention, and a match attempt for an unanchored pattern fails
+when the current starting position is at a CRLF sequence, and the pattern
+contains no explicit matches for CR or LF characters, the match position is
+advanced by two characters instead of one, in other words, to after the CRLF.
+</P>
+<P>
+The above rule is a compromise that makes the most common cases work as
+expected. For example, if the pattern is .+A (and the PCRE2_DOTALL option is
+not set), it does not match the string "\r\nA" because, after failing at the
+start, it skips both the CR and the LF before retrying. However, the pattern
+[\r\n]A does match that string, because it contains an explicit CR or LF
+reference, and so advances only by one character after the first failure.
+</P>
+<P>
+An explicit match for CR of LF is either a literal appearance of one of those
+characters in the pattern, or one of the \r or \n escape sequences. Implicit
+matches such as [^X] do not count, nor does \s, even though it includes CR and
+LF in the characters that it matches.
+</P>
+<P>
+Notwithstanding the above, anomalous effects may still occur when CRLF is a

+In general, a pattern matches a certain portion of the subject, and in

+book, this is called "capturing" in what follows, and the phrase "capturing
+subpattern" or "capturing group" is used for a fragment of a pattern that picks
+out a substring. PCRE2 supports several other kinds of parenthesized subpattern
+that do not cause substrings to be captured. The <b>pcre2_pattern_info()</b>
+function can be used to find out how many capturing subpatterns there are in a

+Within the ovector, the first in each pair of values is set to the offset of
+the first code unit of a substring, and the second is set to the offset of the

+offsets, not character offsets. That is, they are byte offsets in the 8-bit

+library.
+</P>
+<P>
+After a partial match (error return PCRE2_ERROR_PARTIAL), only the first pair

+identify the part of the subject that was partially matched. See the
+<a href="pcre2partial.html"><b>pcre2partial</b></a>
+documentation for details of partial matching.
+</P>
+<P>
+After a successful match, the first pair of offsets identifies the portion of
+the subject string that was matched by the entire pattern. The next pair is
+used for the first capturing subpattern, and so on. The value returned by
+<b>pcre2_match()</b> is one more than the highest numbered pair that has been
+set. For example, if two substrings have been captured, the returned value is
+3. If there are no capturing subpatterns, the return value from a successful
+match is 1, indicating that just the first pair of offsets has been set.
+</P>
+<P>
+If a pattern uses the \K escape sequence within a positive assertion, the
+reported start of a successful match can be greater than the end of the match.
+For example, if the pattern (?=ab\K) is matched against "ab", the start and
+end offset values for the match are 2 and 0.
+</P>
+<P>
+If a capturing subpattern group is matched repeatedly within a single match
+operation, it is the last portion of the subject that it matched that is
+returned.
+</P>
+<P>
+If the ovector is too small to hold all the captured substring offsets, as much
+as possible is filled in, and the function returns a value of zero. If captured
+substrings are not of interest, <b>pcre2_match()</b> may be called with a match
+data block whose ovector is of minimum length (that is, one pair). However, if
+the pattern contains back references and the <i>ovector</i> is not big enough to
+remember the related substrings, PCRE2 has to get additional memory for use
+during matching. Thus it is usually advisable to set up a match data block
+containing an ovector of reasonable size.
+</P>
+<P>
+It is possible for capturing subpattern number <i>n+1</i> to match some part of
+the subject when subpattern <i>n</i> has not been used at all. For example, if
+the string "abc" is matched against the pattern (a|(z))(bc) the return from the
+function is 4, and subpatterns 1 and 3 are matched, but 2 is not. When this
+happens, both values in the offset pairs corresponding to unused subpatterns
+are set to PCRE2_UNSET.
+</P>
+<P>
+Offset values that correspond to unused subpatterns at the end of the
+expression are also set to PCRE2_UNSET. For example, if the string "abc" is
+matched against the pattern (abc)(x(yz)?)? subpatterns 2 and 3 are not matched.
+The return from the function is 2, because the highest used capturing
+subpattern number is 1. The offsets for for the second and third capturing
+subpatterns (assuming the vector is large enough, of course) are set to
+PCRE2_UNSET.
+</P>
+<P>
+Elements in the ovector that do not correspond to capturing parentheses in the
+pattern are never changed. That is, if a pattern contains <i>n</i> capturing
+parentheses, no more than <i>ovector[0]</i> to <i>ovector[2n+1]</i> are set by
+<b>pcre2_match()</b>. The other elements retain whatever values they previously

+PCRE2_SUBSTITUTE_OVERFLOW_LENGTH changes what happens when the output buffer is

+<P>
+PCRE2_SUBSTITUTE_UNKNOWN_UNSET causes references to capturing groups that do

+Firstly, backslash in a replacement string is interpreted as an escape
+character. The usual forms such as \n or \x{ddd} can be used to specify
+particular character codes, and backslash followed by any non-alphanumeric
+character quotes that character. Extended quoting can be coded using \Q...\E,
+exactly as in pattern strings.
+</P>
+<P>
+There are also four escape sequences for forcing the case of inserted letters.
+The insertion mechanism has three states: no case forcing, force upper case,
+and force lower case. The escape sequences change the current state: \U and
+\L change to upper or lower case forcing, respectively, and \E (when not
+terminating a \Q quoted sequence) reverts to no case forcing. The sequences
+\u and \l force the next character (if it is a letter) to upper or lower
+case, respectively, and then the state automatically reverts to no case
+forcing. Case forcing applies to all inserted characters, including those from
+captured groups and letters within \Q...\E quoted sequences.
+</P>
+<P>
+Note that case forcing sequences such as \U...\E do not nest. For example,
+the result of processing "\Uaa\LBB\Ecc\E" is "AAbbcc"; the final \E has no
+effect.
+</P>
+<P>
+The second effect of setting PCRE2_SUBSTITUTE_EXTENDED is to add more
+flexibility to group substitution. The syntax is similar to that used by Bash:
+<pre>
+ ${<n>:-<string>}
+ ${<n>:+<string1>:<string2>}
+</pre>
+As before, <n> may be a group number or a name. The first form specifies a
+default value. If group <n> is set, its value is inserted; if not, <string> is
+expanded and the result inserted. The second form specifies strings that are
+expanded and inserted when group <n> is set or unset, respectively. The first
+form is just a convenient shorthand for
+<pre>
+ ${<n>:+${<n>}:<string>}
+</pre>
+Backslash can be used to escape colons and closing curly brackets in the
+replacement strings. A change of the case forcing state within a replacement
+string remains in force afterwards, as shown in this <b>pcre2test</b> example:
+<pre>
+ /(some)?(body)/substitute_extended,replace=${1:+\U:\L}HeLLo
+ body
+ 1: hello
+ somebody
+ 1: HELLO
+</pre>
+The PCRE2_SUBSTITUTE_UNSET_EMPTY option does not affect these extended
+substitutions. However, PCRE2_SUBSTITUTE_UNKNOWN_UNSET does cause unknown
+groups in the extended syntax forms to be treated as unset.
+</P>
+<P>
+If successful, <b>pcre2_substitute()</b> returns the number of replacements that
+were made. This may be zero if no matches were found, and is never greater than
+1 unless PCRE2_SUBSTITUTE_GLOBAL is set.
+</P>
+<P>
+In the event of an error, a negative error code is returned. Except for
+PCRE2_ERROR_NOMATCH (which is never returned), errors from <b>pcre2_match()</b>
+are passed straight back.
+</P>
+<P>
+PCRE2_ERROR_NOSUBSTRING is returned for a non-existent substring insertion,
+unless PCRE2_SUBSTITUTE_UNKNOWN_UNSET is set.
+</P>
+<P>
+PCRE2_ERROR_UNSET is returned for an unset substring insertion (including an
+unknown substring when PCRE2_SUBSTITUTE_UNKNOWN_UNSET is set) when the simple
+(non-extended) syntax is used and PCRE2_SUBSTITUTE_UNSET_EMPTY is not set.
+</P>
+<P>
+PCRE2_ERROR_NOMEMORY is returned if the output buffer is not big enough. If the
+PCRE2_SUBSTITUTE_OVERFLOW_LENGTH option is set, the size of buffer that is
+needed is returned via <i>outlengthptr</i>. Note that this does not happen by
+default.
+</P>
+<P>
+PCRE2_ERROR_BADREPLACEMENT is used for miscellaneous syntax errors in the
+replacement string, with more particular errors being PCRE2_ERROR_BADREPESCAPE
+(invalid escape sequence), PCRE2_ERROR_REPMISSING_BRACE (closing curly bracket
+not found), PCRE2_BADSUBSTITUTION (syntax error in extended group
+substitution), and PCRE2_BADSUBPATTERN (the pattern match ended before it
+started, which can happen if \K is used in an assertion).
+</P>
+<P>
+As for all PCRE2 errors, a text message that describes the error can be
+obtained by calling <b>pcre2_get_error_message()</b>.
+</P>

+When a pattern is compiled with the PCRE2_DUPNAMES option, names for

+for subpatterns with the same number, created by using the (?| feature. Indeed,
+if such subpatterns are named, they are required to use the same names.
+</P>
+<P>
+Normally, patterns with duplicate names are such that in any one match, only

+</P>
+<P>

+<P>
+If you want to get full details of all captured substrings for a given name,
+you must use the <b>pcre2_substring_nametable_scan()</b> function. The first
+argument is the compiled pattern, and the second is the name. If the third and
+fourth arguments are NULL, the function returns a group number for a unique
+name, or PCRE2_ERROR_NOUNIQUESUBSTRING otherwise.
+</P>
+<P>
+When the third and fourth arguments are not NULL, they must be pointers to
+variables that are updated by the function. After it has run, they point to the

+The format of the name table is described

+The traditional matching function uses a similar algorithm to Perl, which stops

+find all possible matches, or the longest possible match at a given position,
+consider using the alternative matching function (see below) instead. If you
+cannot use the alternative function, you can kludge it up by making use of the
+callout facility, which is described in the
+<a href="pcre2callout.html"><b>pcre2callout</b></a>

+</P>
+<P>
+What you have to do is to insert a callout right at the end of the pattern.
+When your callout function is called, extract and save the current matched
+substring. Then return 1, which forces <b>pcre2_match()</b> to backtrack and try
+other alternatives. Ultimately, when it runs out of matches,
+<b>pcre2_match()</b> will yield PCRE2_ERROR_NOMATCH.

+<b> int *<i>workspace</i>, PCRE2_SIZE <i>wscount</i>);</b>
+</P>
+<P>
+The function <b>pcre2_dfa_match()</b> is called to match a subject string
+against a compiled pattern, using a matching algorithm that scans the subject
+string just once, and does not backtrack. This has different characteristics to
+the normal algorithm, and is not compatible with Perl. Some of the features of
+PCRE2 patterns are not supported. Nevertheless, there are times when this kind
+of matching can be useful. For a discussion of the two matching algorithms, and
+a list of features that <b>pcre2_dfa_match()</b> does not support, see the
+<a href="pcre2matching.html"><b>pcre2matching</b></a>
+documentation.
+</P>
+<P>
+The arguments for the <b>pcre2_dfa_match()</b> function are the same as for
+<b>pcre2_match()</b>, plus two extras. The ovector within the match data block
+is used in a different way, and this is described below. The other common
+arguments are used in the same way as for <b>pcre2_match()</b>, so their
+description is not repeated here.
+</P>
+<P>
+The two additional arguments provide workspace for the function. The workspace
+vector should contain at least 20 elements. It is used for keeping track of
+multiple paths through the pattern tree. More workspace is needed for patterns
+and subjects where there are a lot of potential matches.
+</P>
+<P>
+Here is an example of a simple call to <b>pcre2_dfa_match()</b>:
+<pre>
+ int wspace[20];
+ pcre2_match_data *md = pcre2_match_data_create(4, NULL);
+ int rc = pcre2_dfa_match(
+ re, /* result of pcre2_compile() */
+ "some string", /* the subject string */
+ 11, /* the length of the subject string */
+ 0, /* start at offset 0 in the subject */
+ 0, /* default options */
+ match_data, /* the match data block */
+ NULL, /* a match context; NULL means use defaults */
+ wspace, /* working space vector */
+ 20); /* number of elements (NOT size in bytes) */
+</PRE>
+</P>
+<br><b>
+Option bits for <b>pcre_dfa_match()</b>
+</b><br>
+<P>
+The unused bits of the <i>options</i> argument for <b>pcre2_dfa_match()</b> must
+be zero. The only bits that may be set are PCRE2_ANCHORED, PCRE2_NOTBOL,
+PCRE2_NOTEOL, PCRE2_NOTEMPTY, PCRE2_NOTEMPTY_ATSTART, PCRE2_NO_UTF_CHECK,
+PCRE2_PARTIAL_HARD, PCRE2_PARTIAL_SOFT, PCRE2_DFA_SHORTEST, and
+PCRE2_DFA_RESTART. All but the last four of these are exactly the same as for
+<b>pcre2_match()</b>, so their description is not repeated here.
+<pre>
+ PCRE2_PARTIAL_HARD
+ PCRE2_PARTIAL_SOFT
+</pre>
+These have the same general effect as they do for <b>pcre2_match()</b>, but the
+details are slightly different. When PCRE2_PARTIAL_HARD is set for
+<b>pcre2_dfa_match()</b>, it returns PCRE2_ERROR_PARTIAL if the end of the
+subject is reached and there is still at least one matching possibility that
+requires additional characters. This happens even if some complete matches have
+already been found. When PCRE2_PARTIAL_SOFT is set, the return code
+PCRE2_ERROR_NOMATCH is converted into PCRE2_ERROR_PARTIAL if the end of the
+subject is reached, there have been no complete matches, but there is still at
+least one matching possibility. The portion of the string that was inspected
+when the longest partial match was found is set as the first matching string in
+both cases. There is a more detailed discussion of partial and multi-segment
+matching, with examples, in the
+<a href="pcre2partial.html"><b>pcre2partial</b></a>
+documentation.
+<pre>
+ PCRE2_DFA_SHORTEST
+</pre>
+Setting the PCRE2_DFA_SHORTEST option causes the matching algorithm to stop as
+soon as it has found one match. Because of the way the alternative algorithm
+works, this is necessarily the shortest possible match at the first possible
+matching point in the subject string.
+<pre>
+ PCRE2_DFA_RESTART
+</pre>
+When <b>pcre2_dfa_match()</b> returns a partial match, it is possible to call it
+again, with additional subject characters, and have it continue with the same
+match. The PCRE2_DFA_RESTART option requests this action; when it is set, the
+<i>workspace</i> and <i>wscount</i> options must reference the same vector as
+before because data about the match so far is left in them after a partial
+match. There is more discussion of this facility in the
+<a href="pcre2partial.html"><b>pcre2partial</b></a>
+documentation.
+</P>
+<br><b>
+Successful returns from <b>pcre2_dfa_match()</b>
+</b><br>
+<P>
+When <b>pcre2_dfa_match()</b> succeeds, it may have matched more than one
+substring in the subject. Note, however, that all the matches from one run of
+the function start at the same point in the subject. The shorter matches are
+all initial substrings of the longer matches. For example, if the pattern
+<pre>
+ <.*>
+</pre>
+is matched against the string
+<pre>
+ This is <something> <something else> <something further> no more
+</pre>
+the three matched strings are
+<pre>
+ <something> <something else> <something further>
+ <something> <something else>
+ <something>
+</pre>
+On success, the yield of the function is a number greater than zero, which is
+the number of matched substrings. The offsets of the substrings are returned in
+the ovector, and can be extracted by number in the same way as for
+<b>pcre2_match()</b>, but the numbers bear no relation to any capturing groups
+that may exist in the pattern, because DFA matching does not support group
+capture.
+</P>
+<P>
+Calls to the convenience functions that extract substrings by name
+return the error PCRE2_ERROR_DFA_UFUNC (unsupported function) if used after a
+DFA match. The convenience functions that extract substrings by number never
+return PCRE2_ERROR_NOSUBSTRING, and the meanings of some other errors are
+slightly different:
+<pre>
+ PCRE2_ERROR_UNAVAILABLE
+</pre>
+The ovector is not big enough to include a slot for the given substring number.
+<pre>
+ PCRE2_ERROR_UNSET
+</pre>
+There is a slot in the ovector for this substring, but there were insufficient
+matches to fill it.
+</P>
+<P>
+The matched strings are stored in the ovector in reverse order of length; that
+is, the longest matching string is first. If there were too many matches to fit
+into the ovector, the yield of the function is zero, and the vector is filled
+with the longest matches.
+</P>
+<P>
+NOTE: PCRE2's "auto-possessification" optimization usually applies to character
+repeats at the end of a pattern (as well as internally). For example, the
+pattern "a\d+" is compiled as if it were "a\d++". For DFA matching, this
+means that only one possible match is found. If you really do want multiple
+matches in such cases, either use an ungreedy repeat auch as "a\d+?" or set
+the PCRE2_NO_AUTO_POSSESS option when compiling.
+</P>
+<br><b>
+Error returns from <b>pcre2_dfa_match()</b>
+</b><br>
+<P>
+The <b>pcre2_dfa_match()</b> function returns a negative number when it fails.
+Many of the errors are the same as for <b>pcre2_match()</b>, as described
+<a href="#errorlist">above.</a>
+There are in addition the following errors that are specific to
+<b>pcre2_dfa_match()</b>:
+<pre>
+ PCRE2_ERROR_DFA_UITEM
+</pre>
+This return is given if <b>pcre2_dfa_match()</b> encounters an item in the
+pattern that it does not support, for instance, the use of \C in a UTF mode or
+a back reference.
+<pre>
+ PCRE2_ERROR_DFA_UCOND
+</pre>
+This return is given if <b>pcre2_dfa_match()</b> encounters a condition item
+that uses a back reference for the condition, or a test for recursion in a
+specific group. These are not supported.
+<pre>
+ PCRE2_ERROR_DFA_WSSIZE
+</pre>
+This return is given if <b>pcre2_dfa_match()</b> runs out of space in the
+<i>workspace</i> vector.
+<pre>
+ PCRE2_ERROR_DFA_RECURSE
+</pre>
+When a recursive subpattern is processed, the matching function calls itself
+recursively, using private memory for the ovector and <i>workspace</i>. This
+error is given if the internal ovector is not large enough. This should be
+extremely rare, as a vector of size 1000 is used.
+<pre>
+ PCRE2_ERROR_DFA_BADRESTART
+</pre>
+When <b>pcre2_dfa_match()</b> is called with the <b>PCRE2_DFA_RESTART</b> option,
+some plausibility checks are made on the contents of the workspace, which
+should contain data about the previous partial match. If any of these checks
+fail, this error is given.

+PCRE2 is distributed with a <b>configure</b> script that can be used to build
+the library in Unix-like environments using the applications known as
+Autotools. Also in the distribution are files to support building using
+<b>CMake</b> instead of <b>configure</b>. The text file
+<a href="README.txt"><b>README</b></a>
+contains general information about building with Autotools (some of which is
+repeated below), and also has some comments about building on various operating
+systems. There is a lot more information about building PCRE2 without using
+Autotools (including information about using <b>CMake</b> and building "by
+hand") in the text file called
+<a href="NON-AUTOTOOLS-BUILD.txt"><b>NON-AUTOTOOLS-BUILD</b>.</a>
+You should consult this file as well as the
+<a href="README.txt"><b>README</b></a>
+file if you are building in a non-Unix-like environment.
+</P>
+<br><a name="SEC2" href="#TOC1">PCRE2 BUILD-TIME OPTIONS</a><br>
+<P>
+The rest of this document describes the optional features of PCRE2 that can be
+selected when the library is compiled. It assumes use of the <b>configure</b>
+script, where the optional features are selected or deselected by providing
+options to <b>configure</b> before running the <b>make</b> command. However, the
+same options can be selected in both Unix-like and non-Unix-like environments
+if you are using <b>CMake</b> instead of <b>configure</b> to build PCRE2.
+</P>
+<P>
+If you are not using Autotools or <b>CMake</b>, option selection can be done by
+editing the <b>config.h</b> file, or by passing parameter settings to the
+compiler, as described in
+<a href="NON-AUTOTOOLS-BUILD.txt"><b>NON-AUTOTOOLS-BUILD</b>.</a>
+</P>
+<P>
+The complete list of options for <b>configure</b> (which includes the standard
+ones such as the selection of the installation directory) can be obtained by
+running
+<pre>
+ ./configure --help
+</pre>
+The following sections include descriptions of options whose names begin with
+--enable or --disable. These settings specify changes to the defaults for the
+<b>configure</b> command. Because of the way that <b>configure</b> works,
+--enable and --disable always come in pairs, so the complementary option always
+exists as well, but as it specifies the default, it is not described.
+</P>
+<br><a name="SEC3" href="#TOC1">BUILDING 8-BIT, 16-BIT AND 32-BIT LIBRARIES</a><br>
+<P>
+By default, a library called <b>libpcre2-8</b> is built, containing functions
+that take string arguments contained in vectors of bytes, interpreted either as
+single-byte characters, or UTF-8 strings. You can also build two other
+libraries, called <b>libpcre2-16</b> and <b>libpcre2-32</b>, which process
+strings that are contained in vectors of 16-bit and 32-bit code units,
+respectively. These can be interpreted either as single-unit characters or
+UTF-16/UTF-32 strings. To build these additional libraries, add one or both of
+the following to the <b>configure</b> command:
+<pre>
+ --enable-pcre2-16
+ --enable-pcre2-32
+</pre>
+If you do not want the 8-bit library, add
+<pre>
+ --disable-pcre2-8
+</pre>
+as well. At least one of the three libraries must be built. Note that the POSIX
+wrapper is for the 8-bit library only, and that <b>pcre2grep</b> is an 8-bit
+program. Neither of these are built if you select only the 16-bit or 32-bit
+libraries.
+</P>
+<br><a name="SEC4" href="#TOC1">BUILDING SHARED AND STATIC LIBRARIES</a><br>
+<P>
+The Autotools PCRE2 building process uses <b>libtool</b> to build both shared
+and static libraries by default. You can suppress an unwanted library by adding
+one of
+<pre>
+ --disable-shared
+ --disable-static
+</pre>
+to the <b>configure</b> command.
+</P>
+<br><a name="SEC5" href="#TOC1">UNICODE AND UTF SUPPORT</a><br>
+<P>
+By default, PCRE2 is built with support for Unicode and UTF character strings.
+To build it without Unicode support, add
+<pre>
+ --disable-unicode
+</pre>
+to the <b>configure</b> command. This setting applies to all three libraries. It
+is not possible to build one library with Unicode support, and another without,
+in the same configuration.
+</P>
+<P>
+Of itself, Unicode support does not make PCRE2 treat strings as UTF-8, UTF-16
+or UTF-32. To do that, applications that use the library can set the PCRE2_UTF
+option when they call <b>pcre2_compile()</b> to compile a pattern.
+Alternatively, patterns may be started with (*UTF) unless the application has
+locked this out by setting PCRE2_NEVER_UTF.
+</P>
+<P>
+UTF support allows the libraries to process character code points up to
+0x10ffff in the strings that they handle. It also provides support for
+accessing the Unicode properties of such characters, using pattern escapes such
+as \P, \p, and \X. Only the general category properties such as <i>Lu</i> and
+<i>Nd</i> are supported. Details are given in the
+<a href="pcre2pattern.html"><b>pcre2pattern</b></a>
+documentation.
+</P>
+<P>
+Pattern escapes such as \d and \w do not by default make use of Unicode
+properties. The application can request that they do by setting the PCRE2_UCP
+option. Unless the application has set PCRE2_NEVER_UCP, a pattern may also
+request this by starting with (*UCP).
+</P>
+<br><a name="SEC6" href="#TOC1">DISABLING THE USE OF \C</a><br>
+<P>
+The \C escape sequence, which matches a single code unit, even in a UTF mode,
+can cause unpredictable behaviour because it may leave the current matching
+point in the middle of a multi-code-unit character. The application can lock it
+out by setting the PCRE2_NEVER_BACKSLASH_C option when calling
+<b>pcre2_compile()</b>. There is also a build-time option
+<pre>
+ --enable-never-backslash-C
+</pre>
+(note the upper case C) which locks out the use of \C entirely.
+</P>
+<br><a name="SEC7" href="#TOC1">JUST-IN-TIME COMPILER SUPPORT</a><br>
+<P>
+Just-in-time compiler support is included in the build by specifying
+<pre>
+ --enable-jit
+</pre>
+This support is available only for certain hardware architectures. If this
+option is set for an unsupported architecture, a building error occurs.
+See the
+<a href="pcre2jit.html"><b>pcre2jit</b></a>
+documentation for a discussion of JIT usage. When JIT support is enabled,
+pcre2grep automatically makes use of it, unless you add
+<pre>
+ --disable-pcre2grep-jit
+</pre>
+to the "configure" command.
+</P>
+<br><a name="SEC8" href="#TOC1">NEWLINE RECOGNITION</a><br>
+<P>
+By default, PCRE2 interprets the linefeed (LF) character as indicating the end
+of a line. This is the normal newline character on Unix-like systems. You can
+compile PCRE2 to use carriage return (CR) instead, by adding
+<pre>
+ --enable-newline-is-cr
+</pre>
+to the <b>configure</b> command. There is also an --enable-newline-is-lf option,
+which explicitly specifies linefeed as the newline character.
+</P>
+<P>
+Alternatively, you can specify that line endings are to be indicated by the
+two-character sequence CRLF (CR immediately followed by LF). If you want this,
+add
+<pre>
+ --enable-newline-is-crlf
+</pre>
+to the <b>configure</b> command. There is a fourth option, specified by
+<pre>
+ --enable-newline-is-anycrlf
+</pre>
+which causes PCRE2 to recognize any of the three sequences CR, LF, or CRLF as
+indicating a line ending. Finally, a fifth option, specified by
+<pre>
+ --enable-newline-is-any
+</pre>
+causes PCRE2 to recognize any Unicode newline sequence. The Unicode newline
+sequences are the three just mentioned, plus the single characters VT (vertical
+tab, U+000B), FF (form feed, U+000C), NEL (next line, U+0085), LS (line
+separator, U+2028), and PS (paragraph separator, U+2029).
+</P>
+<P>
+Whatever default line ending convention is selected when PCRE2 is built can be
+overridden by applications that use the library. At build time it is
+conventional to use the standard for your operating system.
+</P>
+<br><a name="SEC9" href="#TOC1">WHAT \R MATCHES</a><br>
+<P>
+By default, the sequence \R in a pattern matches any Unicode newline sequence,
+independently of what has been selected as the line ending sequence. If you
+specify
+<pre>
+ --enable-bsr-anycrlf
+</pre>
+the default is changed so that \R matches only CR, LF, or CRLF. Whatever is
+selected when PCRE2 is built can be overridden by applications that use the
+called.
+</P>
+<br><a name="SEC10" href="#TOC1">HANDLING VERY LARGE PATTERNS</a><br>
+<P>
+Within a compiled pattern, offset values are used to point from one part to
+another (for example, from an opening parenthesis to an alternation
+metacharacter). By default, in the 8-bit and 16-bit libraries, two-byte values
+are used for these offsets, leading to a maximum size for a compiled pattern of
+around 64K code units. This is sufficient to handle all but the most gigantic
+patterns. Nevertheless, some people do want to process truly enormous patterns,
+so it is possible to compile PCRE2 to use three-byte or four-byte offsets by
+adding a setting such as
+<pre>
+ --with-link-size=3
+</pre>
+to the <b>configure</b> command. The value given must be 2, 3, or 4. For the
+16-bit library, a value of 3 is rounded up to 4. In these libraries, using
+longer offsets slows down the operation of PCRE2 because it has to load
+additional data when handling them. For the 32-bit library the value is always
+4 and cannot be overridden; the value of --with-link-size is ignored.
+</P>
+<br><a name="SEC11" href="#TOC1">AVOIDING EXCESSIVE STACK USAGE</a><br>
+<P>
+When matching with the <b>pcre2_match()</b> function, PCRE2 implements
+backtracking by making recursive calls to an internal function called
+<b>match()</b>. In environments where the size of the stack is limited, this can
+severely limit PCRE2's operation. (The Unix environment does not usually suffer
+from this problem, but it may sometimes be necessary to increase the maximum
+stack size. There is a discussion in the
+<a href="pcre2stack.html"><b>pcre2stack</b></a>
+documentation.) An alternative approach to recursion that uses memory from the
+heap to remember data, instead of using recursive function calls, has been
+implemented to work round the problem of limited stack size. If you want to
+build a version of PCRE2 that works this way, add
+<pre>
+ --disable-stack-for-recursion
+</pre>
+to the <b>configure</b> command. By default, the system functions <b>malloc()</b>
+and <b>free()</b> are called to manage the heap memory that is required, but
+custom memory management functions can be called instead. PCRE2 runs noticeably
+more slowly when built in this way. This option affects only the
+<b>pcre2_match()</b> function; it is not relevant for <b>pcre2_dfa_match()</b>.
+</P>
+<br><a name="SEC12" href="#TOC1">LIMITING PCRE2 RESOURCE USAGE</a><br>
+<P>
+Internally, PCRE2 has a function called <b>match()</b>, which it calls
+repeatedly (sometimes recursively) when matching a pattern with the
+<b>pcre2_match()</b> function. By controlling the maximum number of times this
+function may be called during a single matching operation, a limit can be
+placed on the resources used by a single call to <b>pcre2_match()</b>. The limit
+can be changed at run time, as described in the
+<a href="pcre2api.html"><b>pcre2api</b></a>
+documentation. The default is 10 million, but this can be changed by adding a
+setting such as
+<pre>
+ --with-match-limit=500000
+</pre>
+to the <b>configure</b> command. This setting has no effect on the
+<b>pcre2_dfa_match()</b> matching function.
+</P>
+<P>
+In some environments it is desirable to limit the depth of recursive calls of
+<b>match()</b> more strictly than the total number of calls, in order to
+restrict the maximum amount of stack (or heap, if --disable-stack-for-recursion
+is specified) that is used. A second limit controls this; it defaults to the
+value that is set for --with-match-limit, which imposes no additional
+constraints. However, you can set a lower limit by adding, for example,
+<pre>
+ --with-match-limit-recursion=10000
+</pre>
+to the <b>configure</b> command. This value can also be overridden at run time.
+</P>
+<br><a name="SEC13" href="#TOC1">CREATING CHARACTER TABLES AT BUILD TIME</a><br>
+<P>
+PCRE2 uses fixed tables for processing characters whose code points are less
+than 256. By default, PCRE2 is built with a set of tables that are distributed
+in the file <i>src/pcre2_chartables.c.dist</i>. These tables are for ASCII codes
+only. If you add
+<pre>
+ --enable-rebuild-chartables
+</pre>
+to the <b>configure</b> command, the distributed tables are no longer used.
+Instead, a program called <b>dftables</b> is compiled and run. This outputs the
+source for new set of tables, created in the default locale of your C run-time
+system. (This method of replacing the tables does not work if you are cross
+compiling, because <b>dftables</b> is run on the local host. If you need to
+create alternative tables when cross compiling, you will have to do so "by
+hand".)
+</P>
+<br><a name="SEC14" href="#TOC1">USING EBCDIC CODE</a><br>
+<P>
+PCRE2 assumes by default that it will run in an environment where the character
+code is ASCII or Unicode, which is a superset of ASCII. This is the case for
+most computer operating systems. PCRE2 can, however, be compiled to run in an
+8-bit EBCDIC environment by adding
+<pre>
+ --enable-ebcdic --disable-unicode
+</pre>
+to the <b>configure</b> command. This setting implies
+--enable-rebuild-chartables. You should only use it if you know that you are in
+an EBCDIC environment (for example, an IBM mainframe operating system).
+</P>
+<P>
+It is not possible to support both EBCDIC and UTF-8 codes in the same version
+of the library. Consequently, --enable-unicode and --enable-ebcdic are mutually
+exclusive.
+</P>
+<P>
+The EBCDIC character that corresponds to an ASCII LF is assumed to have the
+value 0x15 by default. However, in some EBCDIC environments, 0x25 is used. In
+such an environment you should use
+<pre>
+ --enable-ebcdic-nl25
+</pre>
+as well as, or instead of, --enable-ebcdic. The EBCDIC character for CR has the
+same value as in ASCII, namely, 0x0d. Whichever of 0x15 and 0x25 is <i>not</i>
+chosen as LF is made to correspond to the Unicode NEL character (which, in
+Unicode, is 0x85).
+</P>
+<P>
+The options that select newline behaviour, such as --enable-newline-is-cr,
+and equivalent run-time options, refer to these character values in an EBCDIC
+environment.
+</P>
+<br><a name="SEC15" href="#TOC1">PCRE2GREP OPTIONS FOR COMPRESSED FILE SUPPORT</a><br>
+<P>
+By default, <b>pcre2grep</b> reads all files as plain text. You can build it so
+that it recognizes files whose names end in <b>.gz</b> or <b>.bz2</b>, and reads
+them with <b>libz</b> or <b>libbz2</b>, respectively, by adding one or both of
+<pre>
+ --enable-pcre2grep-libz
+ --enable-pcre2grep-libbz2
+</pre>
+to the <b>configure</b> command. These options naturally require that the
+relevant libraries are installed on your system. Configuration will fail if
+they are not.
+</P>
+<br><a name="SEC16" href="#TOC1">PCRE2GREP BUFFER SIZE</a><br>
+<P>
+<b>pcre2grep</b> uses an internal buffer to hold a "window" on the file it is
+scanning, in order to be able to output "before" and "after" lines when it
+finds a match. The size of the buffer is controlled by a parameter whose
+default value is 20K. The buffer itself is three times this size, but because
+of the way it is used for holding "before" lines, the longest line that is
+guaranteed to be processable is the parameter size. You can change the default
+parameter value by adding, for example,
+<pre>
+ --with-pcre2grep-bufsize=50K
+</pre>
+to the <b>configure</b> command. The caller of \fPpcre2grep\fP can override this
+value by using --buffer-size on the command line..
+</P>
+<br><a name="SEC17" href="#TOC1">PCRE2TEST OPTION FOR LIBREADLINE SUPPORT</a><br>
+<P>
+If you add one of
+<pre>
+ --enable-pcre2test-libreadline
+ --enable-pcre2test-libedit
+</pre>
+to the <b>configure</b> command, <b>pcre2test</b> is linked with the
+<b>libreadline</b> or<b>libedit</b> library, respectively, and when its input is
+from a terminal, it reads it using the <b>readline()</b> function. This provides
+line-editing and history facilities. Note that <b>libreadline</b> is
+GPL-licensed, so if you distribute a binary of <b>pcre2test</b> linked in this
+way, there may be licensing issues. These can be avoided by linking instead
+with <b>libedit</b>, which has a BSD licence.
+</P>
+<P>
+Setting --enable-pcre2test-libreadline causes the <b>-lreadline</b> option to be
+added to the <b>pcre2test</b> build. In many operating environments with a
+sytem-installed readline library this is sufficient. However, in some
+environments (e.g. if an unmodified distribution version of readline is in
+use), some extra configuration may be necessary. The INSTALL file for
+<b>libreadline</b> says this:
+<pre>
+ "Readline uses the termcap functions, but does not link with
+ the termcap or curses library itself, allowing applications
+ which link with readline the to choose an appropriate library."
+</pre>
+If your environment has not been set up so that an appropriate library is
+automatically included, you may need to add something like
+<pre>
+ LIBS="-ncurses"
+</pre>
+immediately before the <b>configure</b> command.
+</P>
+<br><a name="SEC18" href="#TOC1">INCLUDING DEBUGGING CODE</a><br>
+<P>
+If you add
+<pre>
+ --enable-debug
+</pre>
+to the <b>configure</b> command, additional debugging code is included in the
+build. This feature is intended for use by the PCRE2 maintainers.
+</P>
+<br><a name="SEC19" href="#TOC1">DEBUGGING WITH VALGRIND SUPPORT</a><br>
+<P>
+If you add
+<pre>
+ --enable-valgrind
+</pre>
+to the <b>configure</b> command, PCRE2 will use valgrind annotations to mark
+certain memory regions as unaddressable. This allows it to detect invalid
+memory accesses, and is mostly useful for debugging PCRE2 itself.
+</P>
+<br><a name="SEC20" href="#TOC1">CODE COVERAGE REPORTING</a><br>
+<P>
+If your C compiler is gcc, you can build a version of PCRE2 that can generate a
+code coverage report for its test suite. To enable this, you must install
+<b>lcov</b> version 1.6 or above. Then specify
+<pre>
+ --enable-coverage
+</pre>
+to the <b>configure</b> command and build PCRE2 in the usual way.
+</P>
+<P>
+Note that using <b>ccache</b> (a caching C compiler) is incompatible with code
+coverage reporting. If you have configured <b>ccache</b> to run automatically
+on your system, you must set the environment variable
+<pre>
+ CCACHE_DISABLE=1
+</pre>
+before running <b>make</b> to build PCRE2, so that <b>ccache</b> is not used.
+</P>
+<P>
+When --enable-coverage is used, the following addition targets are added to the
+<i>Makefile</i>:
+<pre>
+ make coverage
+</pre>
+This creates a fresh coverage report for the PCRE2 test suite. It is equivalent
+to running "make coverage-reset", "make coverage-baseline", "make check", and
+then "make coverage-report".
+<pre>
+ make coverage-reset
+</pre>
+This zeroes the coverage counters, but does nothing else.
+<pre>
+ make coverage-baseline
+</pre>
+This captures baseline coverage information.
+<pre>
+ make coverage-report
+</pre>
+This creates the coverage report.
+<pre>
+ make coverage-clean-report
+</pre>
+This removes the generated coverage report without cleaning the coverage data
+itself.
+<pre>
+ make coverage-clean-data
+</pre>
+This removes the captured coverage data without removing the coverage files
+created at compile time (*.gcno).
+<pre>
+ make coverage-clean
+</pre>
+This cleans all coverage data including the generated coverage report. For more
+information about code coverage, see the <b>gcov</b> and <b>lcov</b>

+<br><a name="SEC2" href="#TOC1">DESCRIPTION</a><br>
+<P>
+PCRE2 provides a feature called "callout", which is a means of temporarily
+passing control to the caller of PCRE2 in the middle of pattern matching. The
+caller of PCRE2 provides an external function by putting its entry point in
+a match context (see <b>pcre2_set_callout()</b> in the
+<a href="pcre2api.html"><b>pcre2api</b></a>
+documentation).
+</P>
+<P>
+Within a regular expression, (?C<arg>) indicates a point at which the external
+function is to be called. Different callout points can be identified by putting
+a number less than 256 after the letter C. The default value is zero.
+Alternatively, the argument may be a delimited string. The starting delimiter
+must be one of ` ' " ^ % # $ { and the ending delimiter is the same as the
+start, except for {, where the ending delimiter is }. If the ending delimiter
+is needed within the string, it must be doubled. For example, this pattern has
+two callout points:
+<pre>
+ (?C1)abc(?C"some ""arbitrary"" text")def
+</pre>
+If the PCRE2_AUTO_CALLOUT option bit is set when a pattern is compiled, PCRE2
+automatically inserts callouts, all with number 255, before each item in the
+pattern. For example, if PCRE2_AUTO_CALLOUT is used with the pattern
+<pre>
+ A(\d{2}|--)
+</pre>
+it is processed as if it were
+<br>
+<br>
+(?C255)A(?C255)((?C255)\d{2}(?C255)|(?C255)-(?C255)-(?C255))(?C255)
+<br>
+<br>
+Notice that there is a callout before and after each parenthesis and
+alternation bar. If the pattern contains a conditional group whose condition is
+an assertion, an automatic callout is inserted immediately before the
+condition. Such a callout may also be inserted explicitly, for example:
+<pre>
+ (?(?C9)(?=a)ab|de) (?(?C%text%)(?!=d)ab|de)
+</pre>
+This applies only to assertion conditions (because they are themselves
+independent groups).
+</P>
+<P>
+Callouts can be useful for tracking the progress of pattern matching. The
+<a href="pcre2test.html"><b>pcre2test</b></a>
+program has a pattern qualifier (/auto_callout) that sets automatic callouts.
+When any callouts are present, the output from <b>pcre2test</b> indicates how
+the pattern is being matched. This is useful information when you are trying to
+optimize the performance of a particular pattern.
+</P>
+<br><a name="SEC3" href="#TOC1">MISSING CALLOUTS</a><br>
+<P>
+You should be aware that, because of optimizations in the way PCRE2 compiles
+and matches patterns, callouts sometimes do not happen exactly as you might
+expect.
+</P>
+<br><b>
+Auto-possessification
+</b><br>
+<P>
+At compile time, PCRE2 "auto-possessifies" repeated items when it knows that
+what follows cannot be part of the repeat. For example, a+[bc] is compiled as
+if it were a++[bc]. The <b>pcre2test</b> output when this pattern is compiled
+with PCRE2_ANCHORED and PCRE2_AUTO_CALLOUT and then applied to the string
+"aaaa" is:
+<pre>
+ --->aaaa
+ +0 ^ a+
+ +2 ^ ^ [bc]
+ No match
+</pre>
+This indicates that when matching [bc] fails, there is no backtracking into a+
+and therefore the callouts that would be taken for the backtracks do not occur.
+You can disable the auto-possessify feature by passing PCRE2_NO_AUTO_POSSESS to
+<b>pcre2_compile()</b>, or starting the pattern with (*NO_AUTO_POSSESS). In this
+case, the output changes to this:
+<pre>
+ --->aaaa
+ +0 ^ a+
+ +2 ^ ^ [bc]
+ +2 ^ ^ [bc]
+ +2 ^ ^ [bc]
+ +2 ^^ [bc]
+ No match
+</pre>
+This time, when matching [bc] fails, the matcher backtracks into a+ and tries
+again, repeatedly, until a+ itself fails.
+</P>
+<br><b>
+Automatic .* anchoring
+</b><br>
+<P>
+By default, an optimization is applied when .* is the first significant item in
+a pattern. If PCRE2_DOTALL is set, so that the dot can match any character, the
+pattern is automatically anchored. If PCRE2_DOTALL is not set, a match can
+start only after an internal newline or at the beginning of the subject, and
+<b>pcre2_compile()</b> remembers this. This optimization is disabled, however,
+if .* is in an atomic group or if there is a back reference to the capturing
+group in which it appears. It is also disabled if the pattern contains (*PRUNE)
+or (*SKIP). However, the presence of callouts does not affect it.
+</P>
+<P>
+For example, if the pattern .*\d is compiled with PCRE2_AUTO_CALLOUT and
+applied to the string "aa", the <b>pcre2test</b> output is:
+<pre>
+ --->aa
+ +0 ^ .*
+ +2 ^ ^ \d
+ +2 ^^ \d
+ +2 ^ \d
+ No match
+</pre>
+This shows that all match attempts start at the beginning of the subject. In
+other words, the pattern is anchored. You can disable this optimization by
+passing PCRE2_NO_DOTSTAR_ANCHOR to <b>pcre2_compile()</b>, or starting the
+pattern with (*NO_DOTSTAR_ANCHOR). In this case, the output changes to:
+<pre>
+ --->aa
+ +0 ^ .*
+ +2 ^ ^ \d
+ +2 ^^ \d
+ +2 ^ \d
+ +0 ^ .*
+ +2 ^^ \d
+ +2 ^ \d
+ No match
+</pre>
+This shows more match attempts, starting at the second subject character.
+Another optimization, described in the next section, means that there is no
+subsequent attempt to match with an empty subject.
+</P>
+<P>
+If a pattern has more than one top-level branch, automatic anchoring occurs if
+all branches are anchorable.
+</P>
+<br><b>
+Other optimizations
+</b><br>
+<P>
+Other optimizations that provide fast "no match" results also affect callouts.
+For example, if the pattern is
+<pre>
+ ab(?C4)cd
+</pre>
+PCRE2 knows that any matching string must contain the letter "d". If the
+subject string is "abyz", the lack of "d" means that matching doesn't ever
+start, and the callout is never reached. However, with "abyd", though the
+result is still no match, the callout is obeyed.
+</P>
+<P>
+PCRE2 also knows the minimum length of a matching string, and will immediately
+give a "no match" return without actually running a match if the subject is not
+long enough, or, for unanchored patterns, if it has been scanned far enough.
+</P>
+<P>
+You can disable these optimizations by passing the PCRE2_NO_START_OPTIMIZE
+option to <b>pcre2_compile()</b>, or by starting the pattern with
+(*NO_START_OPT). This slows down the matching process, but does ensure that
+callouts such as the example above are obeyed.
+<a name="calloutinterface"></a></P>
+<br><a name="SEC4" href="#TOC1">THE CALLOUT INTERFACE</a><br>
+<P>
+During matching, when PCRE2 reaches a callout point, if an external function is
+set in the match context, it is called. This applies to both normal and DFA
+matching. The first argument to the callout function is a pointer to a
+<b>pcre2_callout</b> block. The second argument is the void * callout data that
+was supplied when the callout was set up by calling <b>pcre2_set_callout()</b>
+(see the
+<a href="pcre2api.html"><b>pcre2api</b></a>
+documentation). The callout block structure contains the following fields:
+<pre>
+ uint32_t <i>version</i>;
+ uint32_t <i>callout_number</i>;
+ uint32_t <i>capture_top</i>;
+ uint32_t <i>capture_last</i>;
+ PCRE2_SIZE *<i>offset_vector</i>;
+ PCRE2_SPTR <i>mark</i>;
+ PCRE2_SPTR <i>subject</i>;
+ PCRE2_SIZE <i>subject_length</i>;
+ PCRE2_SIZE <i>start_match</i>;
+ PCRE2_SIZE <i>current_position</i>;
+ PCRE2_SIZE <i>pattern_position</i>;
+ PCRE2_SIZE <i>next_item_length</i>;
+ PCRE2_SIZE <i>callout_string_offset</i>;
+ PCRE2_SIZE <i>callout_string_length</i>;
+ PCRE2_SPTR <i>callout_string</i>;
+</pre>
+The <i>version</i> field contains the version number of the block format. The
+current version is 1; the three callout string fields were added for this
+version. If you are writing an application that might use an earlier release of
+PCRE2, you should check the version number before accessing any of these
+fields. The version number will increase in future if more fields are added,
+but the intention is never to remove any of the existing fields.
+</P>
+<br><b>
+Fields for numerical callouts
+</b><br>
+<P>
+For a numerical callout, <i>callout_string</i> is NULL, and <i>callout_number</i>
+contains the number of the callout, in the range 0-255. This is the number
+that follows (?C for manual callouts; it is 255 for automatically generated
+callouts.
+</P>
+<br><b>
+Fields for string callouts
+</b><br>
+<P>
+For callouts with string arguments, <i>callout_number</i> is always zero, and
+<i>callout_string</i> points to the string that is contained within the compiled
+pattern. Its length is given by <i>callout_string_length</i>. Duplicated ending
+delimiters that were present in the original pattern string have been turned
+into single characters, but there is no other processing of the callout string
+argument. An additional code unit containing binary zero is present after the
+string, but is not included in the length. The delimiter that was used to start
+the string is also stored within the pattern, immediately before the string
+itself. You can access this delimiter as <i>callout_string</i>[-1] if you need
+it.
+</P>
+<P>
+The <i>callout_string_offset</i> field is the code unit offset to the start of
+the callout argument string within the original pattern string. This is
+provided for the benefit of applications such as script languages that might
+need to report errors in the callout string within the pattern.
+</P>
+<br><b>
+Fields for all callouts
+</b><br>
+<P>
+The remaining fields in the callout block are the same for both kinds of
+callout.
+</P>
+<P>
+The <i>offset_vector</i> field is a pointer to the vector of capturing offsets
+(the "ovector") that was passed to the matching function in the match data
+block. When <b>pcre2_match()</b> is used, the contents can be inspected in
+order to extract substrings that have been matched so far, in the same way as
+for extracting substrings after a match has completed. For the DFA matching
+function, this field is not useful.
+</P>
+<P>
+The <i>subject</i> and <i>subject_length</i> fields contain copies of the values
+that were passed to the matching function.
+</P>
+<P>
+The <i>start_match</i> field normally contains the offset within the subject at
+which the current match attempt started. However, if the escape sequence \K
+has been encountered, this value is changed to reflect the modified starting
+point. If the pattern is not anchored, the callout function may be called
+several times from the same point in the pattern for different starting points
+in the subject.
+</P>
+<P>
+The <i>current_position</i> field contains the offset within the subject of the
+current match pointer.
+</P>
+<P>
+When the <b>pcre2_match()</b> is used, the <i>capture_top</i> field contains one
+more than the number of the highest numbered captured substring so far. If no
+substrings have been captured, the value of <i>capture_top</i> is one. This is
+always the case when the DFA functions are used, because they do not support
+captured substrings.
+</P>
+<P>
+The <i>capture_last</i> field contains the number of the most recently captured
+substring. However, when a recursion exits, the value reverts to what it was
+outside the recursion, as do the values of all captured substrings. If no
+substrings have been captured, the value of <i>capture_last</i> is 0. This is
+always the case for the DFA matching functions.
+</P>
+<P>
+The <i>pattern_position</i> field contains the offset in the pattern string to
+the next item to be matched.
+</P>
+<P>
+The <i>next_item_length</i> field contains the length of the next item to be
+matched in the pattern string. When the callout immediately precedes an
+alternation bar, a closing parenthesis, or the end of the pattern, the length
+is zero. When the callout precedes an opening parenthesis, the length is that
+of the entire subpattern.
+</P>
+<P>
+The <i>pattern_position</i> and <i>next_item_length</i> fields are intended to
+help in distinguishing between different automatic callouts, which all have the
+same callout number. However, they are set for all callouts, and are used by
+<b>pcre2test</b> to show the next item to be matched when displaying callout
+information.
+</P>
+<P>
+In callouts from <b>pcre2_match()</b> the <i>mark</i> field contains a pointer to
+the zero-terminated name of the most recently passed (*MARK), (*PRUNE), or
+(*THEN) item in the match, or NULL if no such items have been passed. Instances
+of (*PRUNE) or (*THEN) without a name do not obliterate a previous (*MARK). In
+callouts from the DFA matching function this field always contains NULL.
+</P>
+<br><a name="SEC5" href="#TOC1">RETURN VALUES FROM CALLOUTS</a><br>
+<P>
+The external callout function returns an integer to PCRE2. If the value is
+zero, matching proceeds as normal. If the value is greater than zero, matching
+fails at the current point, but the testing of other matching possibilities
+goes ahead, just as if a lookahead assertion had failed. If the value is less
+than zero, the match is abandoned, and the matching function returns the
+negative value.
+</P>
+<P>
+Negative values should normally be chosen from the set of PCRE2_ERROR_xxx
+values. In particular, PCRE2_ERROR_NOMATCH forces a standard "no match"
+failure. The error number PCRE2_ERROR_CALLOUT is reserved for use by callout
+functions; it will never be used by PCRE2 itself.
+</P>
+<br><a name="SEC6" href="#TOC1">CALLOUT ENUMERATION</a><br>
+<P>
+<b>int pcre2_callout_enumerate(const pcre2_code *<i>code</i>,</b>
+<b> int (*<i>callback</i>)(pcre2_callout_enumerate_block *, void *),</b>
+<b> void *<i>user_data</i>);</b>
+<br>
+<br>
+A script language that supports the use of string arguments in callouts might
+like to scan all the callouts in a pattern before running the match. This can
+be done by calling <b>pcre2_callout_enumerate()</b>. The first argument is a
+pointer to a compiled pattern, the second points to a callback function, and
+the third is arbitrary user data. The callback function is called for every
+callout in the pattern in the order in which they appear. Its first argument is
+a pointer to a callout enumeration block, and its second argument is the
+<i>user_data</i> value that was passed to <b>pcre2_callout_enumerate()</b>. The
+data block contains the following fields:
+<pre>
+ <i>version</i> Block version number
+ <i>pattern_position</i> Offset to next item in pattern
+ <i>next_item_length</i> Length of next item in pattern
+ <i>callout_number</i> Number for numbered callouts
+ <i>callout_string_offset</i> Offset to string within pattern
+ <i>callout_string_length</i> Length of callout string
+ <i>callout_string</i> Points to callout string or is NULL
+</pre>
+The version number is currently 0. It will increase if new fields are ever
+added to the block. The remaining fields are the same as their namesakes in the
+<b>pcre2_callout</b> block that is used for callouts during matching, as
+described
+<a href="#calloutinterface">above.</a>
+</P>
+<P>
+Note that the value of <i>pattern_position</i> is unique for each callout.
+However, if a callout occurs inside a group that is quantified with a non-zero
+minimum or a fixed maximum, the group is replicated inside the compiled
+pattern. For example, a pattern such as /(a){2}/ is compiled as if it were
+/(a)(a)/. This means that the callout will be enumerated more than once, but
+with the same value for <i>pattern_position</i> in each case.
+</P>
+<P>
+The callback function should normally return zero. If it returns a non-zero
+value, scanning the pattern stops, and that value is returned from
+<b>pcre2_callout_enumerate()</b>.

+<br><b>
+DIFFERENCES BETWEEN PCRE2 AND PERL
+</b><br>
+<P>
+This document describes the differences in the ways that PCRE2 and Perl handle
+regular expressions. The differences described here are with respect to Perl
+versions 5.10 and above.
+</P>
+<P>
+1. PCRE2 has only a subset of Perl's Unicode support. Details of what it does
+have are given in the
+<a href="pcre2unicode.html"><b>pcre2unicode</b></a>
+page.
+</P>
+<P>
+2. PCRE2 allows repeat quantifiers only on parenthesized assertions, but they
+do not mean what you might think. For example, (?!a){3} does not assert that
+the next three characters are not "a". It just asserts that the next character
+is not "a" three times (in principle: PCRE2 optimizes this to run the assertion
+just once). Perl allows repeat quantifiers on other assertions such as \b, but
+these do not seem to have any use.
+</P>
+<P>
+3. Capturing subpatterns that occur inside negative lookahead assertions are
+counted, but their entries in the offsets vector are never set. Perl sometimes
+(but not always) sets its numerical variables from inside negative assertions.
+</P>
+<P>
+4. The following Perl escape sequences are not supported: \l, \u, \L,
+\U, and \N when followed by a character name or Unicode value. (\N on its
+own, matching a non-newline character, is supported.) In fact these are
+implemented by Perl's general string-handling and are not part of its pattern
+matching engine. If any of these are encountered by PCRE2, an error is
+generated by default. However, if the PCRE2_ALT_BSUX option is set,
+\U and \u are interpreted as ECMAScript interprets them.
+</P>
+<P>
+5. The Perl escape sequences \p, \P, and \X are supported only if PCRE2 is
+built with Unicode support. The properties that can be tested with \p and \P
+are limited to the general category properties such as Lu and Nd, script names
+such as Greek or Han, and the derived properties Any and L&. PCRE2 does support
+the Cs (surrogate) property, which Perl does not; the Perl documentation says
+"Because Perl hides the need for the user to understand the internal
+representation of Unicode characters, there is no need to implement the
+somewhat messy concept of surrogates."
+</P>
+<P>
+6. PCRE2 does support the \Q...\E escape for quoting substrings. Characters
+in between are treated as literals. This is slightly different from Perl in
+that $ and @ are also handled as literals inside the quotes. In Perl, they
+cause variable interpolation (but of course PCRE2 does not have variables).
+Note the following examples:
+<pre>
+ Pattern PCRE2 matches Perl matches
+
+ \Qabc$xyz\E abc$xyz abc followed by the contents of $xyz
+ \Qabc\$xyz\E abc\$xyz abc\$xyz
+ \Qabc\E\$\Qxyz\E abc$xyz abc$xyz
+</pre>
+The \Q...\E sequence is recognized both inside and outside character classes.
+</P>
+<P>
+7. Fairly obviously, PCRE2 does not support the (?{code}) and (??{code})
+constructions. However, there is support for recursive patterns. This is not
+available in Perl 5.8, but it is in Perl 5.10. Also, the PCRE2 "callout"
+feature allows an external function to be called during pattern matching. See
+the
+<a href="pcre2callout.html"><b>pcre2callout</b></a>
+documentation for details.
+</P>
+<P>
+8. Subroutine calls (whether recursive or not) are treated as atomic groups.
+Atomic recursion is like Python, but unlike Perl. Captured values that are set
+outside a subroutine call can be referenced from inside in PCRE2, but not in
+Perl. There is a discussion that explains these differences in more detail in
+the
+<a href="pcre2pattern.html#recursiondifference">section on recursion differences from Perl</a>
+in the
+<a href="pcre2pattern.html"><b>pcre2pattern</b></a>
+page.
+</P>
+<P>
+9. If any of the backtracking control verbs are used in a subpattern that is
+called as a subroutine (whether or not recursively), their effect is confined
+to that subpattern; it does not extend to the surrounding pattern. This is not
+always the case in Perl. In particular, if (*THEN) is present in a group that
+is called as a subroutine, its action is limited to that group, even if the
+group does not contain any | characters. Note that such subpatterns are
+processed as anchored at the point where they are tested.
+</P>
+<P>
+10. If a pattern contains more than one backtracking control verb, the first
+one that is backtracked onto acts. For example, in the pattern
+A(*COMMIT)B(*PRUNE)C a failure in B triggers (*COMMIT), but a failure in C
+triggers (*PRUNE). Perl's behaviour is more complex; in many cases it is the
+same as PCRE2, but there are examples where it differs.
+</P>
+<P>
+11. Most backtracking verbs in assertions have their normal actions. They are
+not confined to the assertion.
+</P>
+<P>
+12. There are some differences that are concerned with the settings of captured
+strings when part of a pattern is repeated. For example, matching "aba" against
+the pattern /^(a(b)?)+$/ in Perl leaves $2 unset, but in PCRE2 it is set to
+"b".
+</P>
+<P>
+13. PCRE2's handling of duplicate subpattern numbers and duplicate subpattern
+names is not as general as Perl's. This is a consequence of the fact the PCRE2
+works internally just with numbers, using an external table to translate
+between numbers and names. In particular, a pattern such as (?|(?<a>A)|(?<b)B),
+where the two capturing parentheses have the same number but different names,
+is not supported, and causes an error at compile time. If it were allowed, it
+would not be possible to distinguish which parentheses matched, because both
+names map to capturing subpattern number 1. To avoid this confusing situation,
+an error is given at compile time.
+</P>
+<P>
+14. Perl recognizes comments in some places that PCRE2 does not, for example,
+between the ( and ? at the start of a subpattern. If the /x modifier is set,
+Perl allows white space between ( and ? (though current Perls warn that this is
+deprecated) but PCRE2 never does, even if the PCRE2_EXTENDED option is set.
+</P>
+<P>
+15. Perl, when in warning mode, gives warnings for character classes such as
+[A-\d] or [a-[:digit:]]. It then treats the hyphens as literals. PCRE2 has no
+warning features, so it gives an error in these cases because they are almost
+certainly user mistakes.
+</P>
+<P>
+16. In PCRE2, the upper/lower case character properties Lu and Ll are not
+affected when case-independent matching is specified. For example, \p{Lu}
+always matches an upper case letter. I think Perl has changed in this respect;
+in the release at the time of writing (5.16), \p{Lu} and \p{Ll} match all
+letters, regardless of case, when case independence is specified.
+</P>
+<P>
+17. PCRE2 provides some extensions to the Perl regular expression facilities.
+Perl 5.10 includes new features that are not in earlier versions of Perl, some
+of which (such as named parentheses) have been in PCRE2 for some time. This
+list is with respect to Perl 5.10:
+<br>
+<br>
+(a) Although lookbehind assertions in PCRE2 must match fixed length strings,
+each alternative branch of a lookbehind assertion can match a different length
+of string. Perl requires them all to have the same length.
+<br>
+<br>
+(b) If PCRE2_DOLLAR_ENDONLY is set and PCRE2_MULTILINE is not set, the $
+meta-character matches only at the very end of the string.
+<br>
+<br>
+(c) A backslash followed by a letter with no special meaning is faulted. (Perl
+can be made to issue a warning.)
+<br>
+<br>
+(d) If PCRE2_UNGREEDY is set, the greediness of the repetition quantifiers is
+inverted, that is, by default they are not greedy, but if followed by a
+question mark they are.
+<br>
+<br>
+(e) PCRE2_ANCHORED can be used at matching time to force a pattern to be tried
+only at the first matching position in the subject string.
+<br>
+<br>
+(f) The PCRE2_NOTBOL, PCRE2_NOTEOL, PCRE2_NOTEMPTY, PCRE2_NOTEMPTY_ATSTART, and
+PCRE2_NO_AUTO_CAPTURE options have no Perl equivalents.
+<br>
+<br>
+(g) The \R escape sequence can be restricted to match only CR, LF, or CRLF
+by the PCRE2_BSR_ANYCRLF option.
+<br>
+<br>
+(h) The callout facility is PCRE2-specific.
+<br>
+<br>
+(i) The partial matching facility is PCRE2-specific.
+<br>
+<br>
+(j) The alternative matching function (<b>pcre2_dfa_match()</b> matches in a
+different way and is not Perl-compatible.
+<br>
+<br>
+(k) PCRE2 recognizes some special sequences such as (*CR) at the start of
+a pattern that set overall options that cannot be changed within the pattern.

+* PCRE2 DEMONSTRATION PROGRAM *
+*************************************************/
+
+/* This is a demonstration program to illustrate a straightforward way of
+calling the PCRE2 regular expression library from a C program. See the
+pcre2sample documentation for a short discussion ("man pcre2sample" if you have
+the PCRE2 man pages installed). PCRE2 is a revised API for the library, and is
+incompatible with the original PCRE API.
+
+There are actually three libraries, each supporting a different code unit
+width. This demonstration program uses the 8-bit library.
+
+In Unix-like environments, if PCRE2 is installed in your standard system
+libraries, you should be able to compile this program using this command:
+
+gcc -Wall pcre2demo.c -lpcre2-8 -o pcre2demo
+
+If PCRE2 is not installed in a standard place, it is likely to be installed
+with support for the pkg-config mechanism. If you have pkg-config, you can
+compile this program using this command:
+
+gcc -Wall pcre2demo.c `pkg-config --cflags --libs libpcre2-8` -o pcre2demo
+
+If you do not have pkg-config, you may have to use this:
+
+gcc -Wall pcre2demo.c -I/usr/local/include -L/usr/local/lib \
+ -R/usr/local/lib -lpcre2-8 -o pcre2demo
+
+Replace "/usr/local/include" and "/usr/local/lib" with wherever the include and
+library files for PCRE2 are installed on your system. Only some operating
+systems (Solaris is one) use the -R option.
+
+Building under Windows:
+
+If you want to statically link this program against a non-dll .a file, you must
+define PCRE2_STATIC before including pcre2.h, so in this environment, uncomment
+the following line. */
+
+/* #define PCRE2_STATIC */

+* If the "-g" option was given on the command line, we want to continue *

+* might think because of the possibility of matching an empty string. *
+* What happens is as follows: *
+* *
+* If the previous match was NOT for an empty string, we can just start *
+* the next match at the end of the previous one. *
+* *
+* If the previous match WAS for an empty string, we can't do that, as it *
+* would lead to an infinite loop. Instead, a call of pcre2_match() is *
+* made with the PCRE2_NOTEMPTY_ATSTART and PCRE2_ANCHORED flags set. The *
+* first of these tells PCRE2 that an empty string at the start of the *
+* subject is not a valid match; other possibilities must be tried. The *
+* second flag restricts PCRE2 to one match attempt at the initial string *
+* position. If this match succeeds, an alternative to the empty string *
+* match has been found, and we can print it and proceed round the loop, *
+* advancing by the length of whatever was found. If this match does not *
+* succeed, we still stay in the loop, advancing by just one character. *
+* In UTF-8 mode, which can be set by (*UTF) in the pattern, this may be *
+* more than one byte. *
+* *
+* However, there is a complication concerned with newlines. When the *
+* newline convention is such that CRLF is a valid newline, we must *
+* advance by two characters rather than one. The newline convention can *
+* be set in the regex by (*CR), etc.; if not, we must find the default. *

+<b>pcre2grep [options] [long options] [pattern] [path1 path2 ...]</b>
+</P>
+<br><a name="SEC2" href="#TOC1">DESCRIPTION</a><br>
+<P>
+<b>pcre2grep</b> searches files for character patterns, in the same way as other
+grep commands do, but it uses the PCRE2 regular expression library to support
+patterns that are compatible with the regular expressions of Perl 5. See
+<a href="pcre2syntax.html"><b>pcre2syntax</b>(3)</a>
+for a quick-reference summary of pattern syntax, or
+<a href="pcre2pattern.html"><b>pcre2pattern</b>(3)</a>
+for a full description of the syntax and semantics of the regular expressions
+that PCRE2 supports.
+</P>
+<P>
+Patterns, whether supplied on the command line or in a separate file, are given
+without delimiters. For example:
+<pre>
+ pcre2grep Thursday /etc/motd
+</pre>
+If you attempt to use delimiters (for example, by surrounding a pattern with
+slashes, as is common in Perl scripts), they are interpreted as part of the
+pattern. Quotes can of course be used to delimit patterns on the command line
+because they are interpreted by the shell, and indeed quotes are required if a
+pattern contains white space or shell metacharacters.
+</P>
+<P>
+The first argument that follows any option settings is treated as the single
+pattern to be matched when neither <b>-e</b> nor <b>-f</b> is present.
+Conversely, when one or both of these options are used to specify patterns, all
+arguments are treated as path names. At least one of <b>-e</b>, <b>-f</b>, or an
+argument pattern must be provided.
+</P>
+<P>
+If no files are specified, <b>pcre2grep</b> reads the standard input. The
+standard input can also be referenced by a name consisting of a single hyphen.
+For example:
+<pre>
+ pcre2grep some-pattern file1 - file3
+</pre>
+Input files are searched line by line. By default, each line that matches a
+pattern is copied to the standard output, and if there is more than one file,
+the file name is output at the start of each line, followed by a colon.
+However, there are options that can change how <b>pcre2grep</b> behaves. In
+particular, the <b>-M</b> option makes it possible to search for strings that
+span line boundaries. What defines a line boundary is controlled by the
+<b>-N</b> (<b>--newline</b>) option.
+</P>
+<P>
+The amount of memory used for buffering files that are being scanned is
+controlled by a parameter that can be set by the <b>--buffer-size</b> option.
+The default value for this parameter is specified when <b>pcre2grep</b> is
+built, with the default default being 20K. A block of memory three times this
+size is used (to allow for buffering "before" and "after" lines). An error
+occurs if a line overflows the buffer.
+</P>
+<P>
+Patterns can be no longer than 8K or BUFSIZ bytes, whichever is the greater.
+BUFSIZ is defined in <b><stdio.h></b>. When there is more than one pattern
+(specified by the use of <b>-e</b> and/or <b>-f</b>), each pattern is applied to
+each line in the order in which they are defined, except that all the <b>-e</b>
+patterns are tried before the <b>-f</b> patterns.
+</P>
+<P>
+By default, as soon as one pattern matches a line, no further patterns are
+considered. However, if <b>--colour</b> (or <b>--color</b>) is used to colour the
+matching substrings, or if <b>--only-matching</b>, <b>--file-offsets</b>, or
+<b>--line-offsets</b> is used to output only the part of the line that matched
+(either shown literally, or as an offset), scanning resumes immediately
+following the match, so that further matches on the same line can be found. If
+there are multiple patterns, they are all tried on the remainder of the line,
+but patterns that follow the one that matched are not tried on the earlier part
+of the line.
+</P>
+<P>
+This behaviour means that the order in which multiple patterns are specified
+can affect the output when one of the above options is used. This is no longer
+the same behaviour as GNU grep, which now manages to display earlier matches
+for later patterns (as long as there is no overlap).
+</P>
+<P>
+Patterns that can match an empty string are accepted, but empty string
+matches are never recognized. An example is the pattern "(super)?(man)?", in
+which all components are optional. This pattern finds all occurrences of both
+"super" and "man"; the output differs from matching with "super|man" when only
+the matching substrings are being shown.
+</P>
+<P>
+If the <b>LC_ALL</b> or <b>LC_CTYPE</b> environment variable is set,
+<b>pcre2grep</b> uses the value to set a locale when calling the PCRE2 library.
+The <b>--locale</b> option can be used to override this.
+</P>
+<br><a name="SEC3" href="#TOC1">SUPPORT FOR COMPRESSED FILES</a><br>
+<P>
+It is possible to compile <b>pcre2grep</b> so that it uses <b>libz</b> or
+<b>libbz2</b> to read files whose names end in <b>.gz</b> or <b>.bz2</b>,
+respectively. You can find out whether your binary has support for one or both
+of these file types by running it with the <b>--help</b> option. If the
+appropriate support is not present, files are treated as plain text. The
+standard input is always so treated.
+</P>
+<br><a name="SEC4" href="#TOC1">BINARY FILES</a><br>
+<P>
+By default, a file that contains a binary zero byte within the first 1024 bytes
+is identified as a binary file, and is processed specially. (GNU grep also
+identifies binary files in this manner.) See the <b>--binary-files</b> option
+for a means of changing the way binary files are handled.
+</P>
+<br><a name="SEC5" href="#TOC1">OPTIONS</a><br>
+<P>
+The order in which some of the options appear can affect the output. For
+example, both the <b>-h</b> and <b>-l</b> options affect the printing of file
+names. Whichever comes later in the command line will be the one that takes
+effect. Similarly, except where noted below, if an option is given twice, the
+later setting is used. Numerical values for options may be followed by K or M,
+to signify multiplication by 1024 or 1024*1024 respectively.
+</P>
+<P>
+<b>--</b>
+This terminates the list of options. It is useful if the next item on the
+command line starts with a hyphen but is not an option. This allows for the
+processing of patterns and file names that start with hyphens.
+</P>
+<P>
+<b>-A</b> <i>number</i>, <b>--after-context=</b><i>number</i>
+Output <i>number</i> lines of context after each matching line. If file names
+and/or line numbers are being output, a hyphen separator is used instead of a
+colon for the context lines. A line containing "--" is output between each
+group of lines, unless they are in fact contiguous in the input file. The value
+of <i>number</i> is expected to be relatively small. However, <b>pcre2grep</b>
+guarantees to have up to 8K of following text available for context output.
+</P>
+<P>
+<b>-a</b>, <b>--text</b>
+Treat binary files as text. This is equivalent to
+<b>--binary-files</b>=<i>text</i>.
+</P>
+<P>
+<b>-B</b> <i>number</i>, <b>--before-context=</b><i>number</i>
+Output <i>number</i> lines of context before each matching line. If file names
+and/or line numbers are being output, a hyphen separator is used instead of a
+colon for the context lines. A line containing "--" is output between each
+group of lines, unless they are in fact contiguous in the input file. The value
+of <i>number</i> is expected to be relatively small. However, <b>pcre2grep</b>
+guarantees to have up to 8K of preceding text available for context output.
+</P>
+<P>
+<b>--binary-files=</b><i>word</i>
+Specify how binary files are to be processed. If the word is "binary" (the
+default), pattern matching is performed on binary files, but the only output is
+"Binary file <name> matches" when a match succeeds. If the word is "text",
+which is equivalent to the <b>-a</b> or <b>--text</b> option, binary files are
+processed in the same way as any other file. In this case, when a match
+succeeds, the output may be binary garbage, which can have nasty effects if
+sent to a terminal. If the word is "without-match", which is equivalent to the
+<b>-I</b> option, binary files are not processed at all; they are assumed not to
+be of interest and are skipped without causing any output or affecting the
+return code.
+</P>
+<P>
+<b>--buffer-size=</b><i>number</i>
+Set the parameter that controls how much memory is used for buffering files
+that are being scanned.
+</P>
+<P>
+<b>-C</b> <i>number</i>, <b>--context=</b><i>number</i>
+Output <i>number</i> lines of context both before and after each matching line.
+This is equivalent to setting both <b>-A</b> and <b>-B</b> to the same value.
+</P>
+<P>
+<b>-c</b>, <b>--count</b>
+Do not output lines from the files that are being scanned; instead output the
+number of matches (or non-matches if <b>-v</b> is used) that would otherwise
+have caused lines to be shown. By default, this count is the same as the number
+of suppressed lines, but if the <b>-M</b> (multiline) option is used (without
+<b>-v</b>), there may be more suppressed lines than the number of matches.
+<br>
+<br>
+If no lines are selected, the number zero is output. If several files are are
+being scanned, a count is output for each of them. However, if the
+<b>--files-with-matches</b> option is also used, only those files whose counts
+are greater than zero are listed. When <b>-c</b> is used, the <b>-A</b>,
+<b>-B</b>, and <b>-C</b> options are ignored.
+</P>
+<P>
+<b>--colour</b>, <b>--color</b>
+If this option is given without any data, it is equivalent to "--colour=auto".
+If data is required, it must be given in the same shell item, separated by an
+equals sign.
+</P>
+<P>
+<b>--colour=</b><i>value</i>, <b>--color=</b><i>value</i>
+This option specifies under what circumstances the parts of a line that matched
+a pattern should be coloured in the output. By default, the output is not
+coloured. The value (which is optional, see above) may be "never", "always", or
+"auto". In the latter case, colouring happens only if the standard output is
+connected to a terminal. More resources are used when colouring is enabled,
+because <b>pcre2grep</b> has to search for all possible matches in a line, not
+just one, in order to colour them all.
+<br>
+<br>
+The colour that is used can be specified by setting the environment variable
+PCRE2GREP_COLOUR or PCRE2GREP_COLOR. The value of this variable should be a
+string of two numbers, separated by a semicolon. They are copied directly into
+the control string for setting colour on a terminal, so it is your
+responsibility to ensure that they make sense. If neither of the environment
+variables is set, the default is "1;31", which gives red.
+</P>
+<P>
+<b>-D</b> <i>action</i>, <b>--devices=</b><i>action</i>
+If an input path is not a regular file or a directory, "action" specifies how
+it is to be processed. Valid values are "read" (the default) or "skip"
+(silently skip the path).
+</P>
+<P>
+<b>-d</b> <i>action</i>, <b>--directories=</b><i>action</i>
+If an input path is a directory, "action" specifies how it is to be processed.
+Valid values are "read" (the default in non-Windows environments, for
+compatibility with GNU grep), "recurse" (equivalent to the <b>-r</b> option), or
+"skip" (silently skip the path, the default in Windows environments). In the
+"read" case, directories are read as if they were ordinary files. In some
+operating systems the effect of reading a directory like this is an immediate
+end-of-file; in others it may provoke an error.
+</P>
+<P>
+<b>-e</b> <i>pattern</i>, <b>--regex=</b><i>pattern</i>, <b>--regexp=</b><i>pattern</i>
+Specify a pattern to be matched. This option can be used multiple times in
+order to specify several patterns. It can also be used as a way of specifying a
+single pattern that starts with a hyphen. When <b>-e</b> is used, no argument
+pattern is taken from the command line; all arguments are treated as file
+names. There is no limit to the number of patterns. They are applied to each
+line in the order in which they are defined until one matches.
+<br>
+<br>
+If <b>-f</b> is used with <b>-e</b>, the command line patterns are matched first,
+followed by the patterns from the file(s), independent of the order in which
+these options are specified. Note that multiple use of <b>-e</b> is not the same
+as a single pattern with alternatives. For example, X|Y finds the first
+character in a line that is X or Y, whereas if the two patterns are given
+separately, with X first, <b>pcre2grep</b> finds X if it is present, even if it
+follows Y in the line. It finds Y only if there is no X in the line. This
+matters only if you are using <b>-o</b> or <b>--colo(u)r</b> to show the part(s)
+of the line that matched.
+</P>
+<P>
+<b>--exclude</b>=<i>pattern</i>
+Files (but not directories) whose names match the pattern are skipped without
+being processed. This applies to all files, whether listed on the command line,
+obtained from <b>--file-list</b>, or by scanning a directory. The pattern is a
+PCRE2 regular expression, and is matched against the final component of the
+file name, not the entire path. The <b>-F</b>, <b>-w</b>, and <b>-x</b> options do
+not apply to this pattern. The option may be given any number of times in order
+to specify multiple patterns. If a file name matches both an <b>--include</b>
+and an <b>--exclude</b> pattern, it is excluded. There is no short form for this
+option.
+</P>
+<P>
+<b>--exclude-from=</b><i>filename</i>
+Treat each non-empty line of the file as the data for an <b>--exclude</b>
+option. What constitutes a newline when reading the file is the operating
+system's default. The <b>--newline</b> option has no effect on this option. This
+option may be given more than once in order to specify a number of files to
+read.
+</P>
+<P>
+<b>--exclude-dir</b>=<i>pattern</i>
+Directories whose names match the pattern are skipped without being processed,
+whatever the setting of the <b>--recursive</b> option. This applies to all
+directories, whether listed on the command line, obtained from
+<b>--file-list</b>, or by scanning a parent directory. The pattern is a PCRE2
+regular expression, and is matched against the final component of the directory
+name, not the entire path. The <b>-F</b>, <b>-w</b>, and <b>-x</b> options do not
+apply to this pattern. The option may be given any number of times in order to
+specify more than one pattern. If a directory matches both <b>--include-dir</b>
+and <b>--exclude-dir</b>, it is excluded. There is no short form for this
+option.
+</P>
+<P>
+<b>-F</b>, <b>--fixed-strings</b>
+Interpret each data-matching pattern as a list of fixed strings, separated by
+newlines, instead of as a regular expression. What constitutes a newline for
+this purpose is controlled by the <b>--newline</b> option. The <b>-w</b> (match
+as a word) and <b>-x</b> (match whole line) options can be used with <b>-F</b>.
+They apply to each of the fixed strings. A line is selected if any of the fixed
+strings are found in it (subject to <b>-w</b> or <b>-x</b>, if present). This
+option applies only to the patterns that are matched against the contents of
+files; it does not apply to patterns specified by any of the <b>--include</b> or
+<b>--exclude</b> options.
+</P>
+<P>
+<b>-f</b> <i>filename</i>, <b>--file=</b><i>filename</i>
+Read patterns from the file, one per line, and match them against
+each line of input. What constitutes a newline when reading the file is the
+operating system's default. The <b>--newline</b> option has no effect on this
+option. Trailing white space is removed from each line, and blank lines are
+ignored. An empty file contains no patterns and therefore matches nothing. See
+also the comments about multiple patterns versus a single pattern with
+alternatives in the description of <b>-e</b> above.
+<br>
+<br>
+If this option is given more than once, all the specified files are
+read. A data line is output if any of the patterns match it. A file name can
+be given as "-" to refer to the standard input. When <b>-f</b> is used, patterns
+specified on the command line using <b>-e</b> may also be present; they are
+tested before the file's patterns. However, no other pattern is taken from the
+command line; all arguments are treated as the names of paths to be searched.
+</P>
+<P>
+<b>--file-list</b>=<i>filename</i>
+Read a list of files and/or directories that are to be scanned from the given
+file, one per line. Trailing white space is removed from each line, and blank
+lines are ignored. These paths are processed before any that are listed on the
+command line. The file name can be given as "-" to refer to the standard input.
+If <b>--file</b> and <b>--file-list</b> are both specified as "-", patterns are
+read first. This is useful only when the standard input is a terminal, from
+which further lines (the list of files) can be read after an end-of-file
+indication. If this option is given more than once, all the specified files are
+read.
+</P>
+<P>
+<b>--file-offsets</b>
+Instead of showing lines or parts of lines that match, show each match as an
+offset from the start of the file and a length, separated by a comma. In this
+mode, no context is shown. That is, the <b>-A</b>, <b>-B</b>, and <b>-C</b>
+options are ignored. If there is more than one match in a line, each of them is
+shown separately. This option is mutually exclusive with <b>--line-offsets</b>
+and <b>--only-matching</b>.
+</P>
+<P>
+<b>-H</b>, <b>--with-filename</b>
+Force the inclusion of the file name at the start of output lines when
+searching a single file. By default, the file name is not shown in this case.
+For matching lines, the file name is followed by a colon; for context lines, a
+hyphen separator is used. If a line number is also being output, it follows the
+file name. When the <b>-M</b> option causes a pattern to match more than one
+line, only the first is preceded by the file name.
+</P>
+<P>
+<b>-h</b>, <b>--no-filename</b>
+Suppress the output file names when searching multiple files. By default,
+file names are shown when multiple files are searched. For matching lines, the
+file name is followed by a colon; for context lines, a hyphen separator is used.
+If a line number is also being output, it follows the file name.
+</P>
+<P>
+<b>--help</b>
+Output a help message, giving brief details of the command options and file
+type support, and then exit. Anything else on the command line is
+ignored.
+</P>
+<P>
+<b>-I</b>
+Ignore binary files. This is equivalent to
+<b>--binary-files</b>=<i>without-match</i>.
+</P>
+<P>
+<b>-i</b>, <b>--ignore-case</b>
+Ignore upper/lower case distinctions during comparisons.
+</P>
+<P>
+<b>--include</b>=<i>pattern</i>
+If any <b>--include</b> patterns are specified, the only files that are
+processed are those that match one of the patterns (and do not match an
+<b>--exclude</b> pattern). This option does not affect directories, but it
+applies to all files, whether listed on the command line, obtained from
+<b>--file-list</b>, or by scanning a directory. The pattern is a PCRE2 regular
+expression, and is matched against the final component of the file name, not
+the entire path. The <b>-F</b>, <b>-w</b>, and <b>-x</b> options do not apply to
+this pattern. The option may be given any number of times. If a file name
+matches both an <b>--include</b> and an <b>--exclude</b> pattern, it is excluded.
+There is no short form for this option.
+</P>
+<P>
+<b>--include-from=</b><i>filename</i>
+Treat each non-empty line of the file as the data for an <b>--include</b>
+option. What constitutes a newline for this purpose is the operating system's
+default. The <b>--newline</b> option has no effect on this option. This option
+may be given any number of times; all the files are read.
+</P>
+<P>
+<b>--include-dir</b>=<i>pattern</i>
+If any <b>--include-dir</b> patterns are specified, the only directories that
+are processed are those that match one of the patterns (and do not match an
+<b>--exclude-dir</b> pattern). This applies to all directories, whether listed
+on the command line, obtained from <b>--file-list</b>, or by scanning a parent
+directory. The pattern is a PCRE2 regular expression, and is matched against
+the final component of the directory name, not the entire path. The <b>-F</b>,
+<b>-w</b>, and <b>-x</b> options do not apply to this pattern. The option may be
+given any number of times. If a directory matches both <b>--include-dir</b> and
+<b>--exclude-dir</b>, it is excluded. There is no short form for this option.
+</P>
+<P>
+<b>-L</b>, <b>--files-without-match</b>
+Instead of outputting lines from the files, just output the names of the files
+that do not contain any lines that would have been output. Each file name is
+output once, on a separate line.
+</P>
+<P>
+<b>-l</b>, <b>--files-with-matches</b>
+Instead of outputting lines from the files, just output the names of the files
+containing lines that would have been output. Each file name is output
+once, on a separate line. Searching normally stops as soon as a matching line
+is found in a file. However, if the <b>-c</b> (count) option is also used,
+matching continues in order to obtain the correct count, and those files that
+have at least one match are listed along with their counts. Using this option
+with <b>-c</b> is a way of suppressing the listing of files with no matches.
+</P>
+<P>
+<b>--label</b>=<i>name</i>
+This option supplies a name to be used for the standard input when file names
+are being output. If not supplied, "(standard input)" is used. There is no
+short form for this option.
+</P>
+<P>
+<b>--line-buffered</b>
+When this option is given, input is read and processed line by line, and the
+output is flushed after each write. By default, input is read in large chunks,
+unless <b>pcre2grep</b> can determine that it is reading from a terminal (which
+is currently possible only in Unix-like environments). Output to terminal is
+normally automatically flushed by the operating system. This option can be
+useful when the input or output is attached to a pipe and you do not want
+<b>pcre2grep</b> to buffer up large amounts of data. However, its use will
+affect performance, and the <b>-M</b> (multiline) option ceases to work.
+</P>
+<P>
+<b>--line-offsets</b>
+Instead of showing lines or parts of lines that match, show each match as a
+line number, the offset from the start of the line, and a length. The line
+number is terminated by a colon (as usual; see the <b>-n</b> option), and the
+offset and length are separated by a comma. In this mode, no context is shown.
+That is, the <b>-A</b>, <b>-B</b>, and <b>-C</b> options are ignored. If there is
+more than one match in a line, each of them is shown separately. This option is
+mutually exclusive with <b>--file-offsets</b> and <b>--only-matching</b>.
+</P>
+<P>
+<b>--locale</b>=<i>locale-name</i>
+This option specifies a locale to be used for pattern matching. It overrides
+the value in the <b>LC_ALL</b> or <b>LC_CTYPE</b> environment variables. If no
+locale is specified, the PCRE2 library's default (usually the "C" locale) is
+used. There is no short form for this option.
+</P>
+<P>
+<b>--match-limit</b>=<i>number</i>
+Processing some regular expression patterns can require a very large amount of
+memory, leading in some cases to a program crash if not enough is available.
+Other patterns may take a very long time to search for all possible matching
+strings. The <b>pcre2_match()</b> function that is called by <b>pcre2grep</b> to
+do the matching has two parameters that can limit the resources that it uses.
+<br>
+<br>
+The <b>--match-limit</b> option provides a means of limiting resource usage
+when processing patterns that are not going to match, but which have a very
+large number of possibilities in their search trees. The classic example is a
+pattern that uses nested unlimited repeats. Internally, PCRE2 uses a function
+called <b>match()</b> which it calls repeatedly (sometimes recursively). The
+limit set by <b>--match-limit</b> is imposed on the number of times this
+function is called during a match, which has the effect of limiting the amount
+of backtracking that can take place.
+<br>
+<br>
+The <b>--recursion-limit</b> option is similar to <b>--match-limit</b>, but
+instead of limiting the total number of times that <b>match()</b> is called, it
+limits the depth of recursive calls, which in turn limits the amount of memory
+that can be used. The recursion depth is a smaller number than the total number
+of calls, because not all calls to <b>match()</b> are recursive. This limit is
+of use only if it is set smaller than <b>--match-limit</b>.
+<br>
+<br>
+There are no short forms for these options. The default settings are specified
+when the PCRE2 library is compiled, with the default default being 10 million.
+</P>
+<P>
+<b>-M</b>, <b>--multiline</b>
+Allow patterns to match more than one line. When this option is given, patterns
+may usefully contain literal newline characters and internal occurrences of ^
+and $ characters. The output for a successful match may consist of more than
+one line. The first is the line in which the match started, and the last is the
+line in which the match ended. If the matched string ends with a newline
+sequence the output ends at the end of that line.
+<br>
+<br>
+When this option is set, the PCRE2 library is called in "multiline" mode.
+However, <b>pcre2grep</b> still processes the input line by line. The difference
+is that a matched string may extend past the end of a line and continue on
+one or more subsequent lines. The newline sequence must be matched as part of
+the pattern. For example, to find the phrase "regular expression" in a file
+where "regular" might be at the end of a line and "expression" at the start of
+the next line, you could use this command:
+<pre>
+ pcre2grep -M 'regular\s+expression' <file>
+</pre>
+The \s escape sequence matches any white space character, including newlines,
+and is followed by + so as to match trailing white space on the first line as
+well as possibly handling a two-character newline sequence.
+<br>
+<br>
+There is a limit to the number of lines that can be matched, imposed by the way
+that <b>pcre2grep</b> buffers the input file as it scans it. However,
+<b>pcre2grep</b> ensures that at least 8K characters or the rest of the file
+(whichever is the shorter) are available for forward matching, and similarly
+the previous 8K characters (or all the previous characters, if fewer than 8K)
+are guaranteed to be available for lookbehind assertions. The <b>-M</b> option
+does not work when input is read line by line (see \fP--line-buffered\fP.)
+</P>
+<P>
+<b>-N</b> <i>newline-type</i>, <b>--newline</b>=<i>newline-type</i>
+The PCRE2 library supports five different conventions for indicating
+the ends of lines. They are the single-character sequences CR (carriage return)
+and LF (linefeed), the two-character sequence CRLF, an "anycrlf" convention,
+which recognizes any of the preceding three types, and an "any" convention, in
+which any Unicode line ending sequence is assumed to end a line. The Unicode
+sequences are the three just mentioned, plus VT (vertical tab, U+000B), FF
+(form feed, U+000C), NEL (next line, U+0085), LS (line separator, U+2028), and
+PS (paragraph separator, U+2029).
+<br>
+<br>
+When the PCRE2 library is built, a default line-ending sequence is specified.
+This is normally the standard sequence for the operating system. Unless
+otherwise specified by this option, <b>pcre2grep</b> uses the library's default.
+The possible values for this option are CR, LF, CRLF, ANYCRLF, or ANY. This
+makes it possible to use <b>pcre2grep</b> to scan files that have come from
+other environments without having to modify their line endings. If the data
+that is being scanned does not agree with the convention set by this option,
+<b>pcre2grep</b> may behave in strange ways. Note that this option does not
+apply to files specified by the <b>-f</b>, <b>--exclude-from</b>, or
+<b>--include-from</b> options, which are expected to use the operating system's
+standard newline sequence.
+</P>
+<P>
+<b>-n</b>, <b>--line-number</b>
+Precede each output line by its line number in the file, followed by a colon
+for matching lines or a hyphen for context lines. If the file name is also
+being output, it precedes the line number. When the <b>-M</b> option causes a
+pattern to match more than one line, only the first is preceded by its line
+number. This option is forced if <b>--line-offsets</b> is used.
+</P>
+<P>
+<b>--no-jit</b>
+If the PCRE2 library is built with support for just-in-time compiling (which
+speeds up matching), <b>pcre2grep</b> automatically makes use of this, unless it
+was explicitly disabled at build time. This option can be used to disable the
+use of JIT at run time. It is provided for testing and working round problems.
+It should never be needed in normal use.
+</P>
+<P>
+<b>-o</b>, <b>--only-matching</b>
+Show only the part of the line that matched a pattern instead of the whole
+line. In this mode, no context is shown. That is, the <b>-A</b>, <b>-B</b>, and
+<b>-C</b> options are ignored. If there is more than one match in a line, each
+of them is shown separately. If <b>-o</b> is combined with <b>-v</b> (invert the
+sense of the match to find non-matching lines), no output is generated, but the
+return code is set appropriately. If the matched portion of the line is empty,
+nothing is output unless the file name or line number are being printed, in
+which case they are shown on an otherwise empty line. This option is mutually
+exclusive with <b>--file-offsets</b> and <b>--line-offsets</b>.
+</P>
+<P>
+<b>-o</b><i>number</i>, <b>--only-matching</b>=<i>number</i>
+Show only the part of the line that matched the capturing parentheses of the
+given number. Up to 32 capturing parentheses are supported, and -o0 is
+equivalent to <b>-o</b> without a number. Because these options can be given
+without an argument (see above), if an argument is present, it must be given in
+the same shell item, for example, -o3 or --only-matching=2. The comments given
+for the non-argument case above also apply to this case. If the specified
+capturing parentheses do not exist in the pattern, or were not set in the
+match, nothing is output unless the file name or line number are being output.
+<br>
+<br>
+If this option is given multiple times, multiple substrings are output, in the
+order the options are given. For example, -o3 -o1 -o3 causes the substrings
+matched by capturing parentheses 3 and 1 and then 3 again to be output. By
+default, there is no separator (but see the next option).
+</P>
+<P>
+<b>--om-separator</b>=<i>text</i>
+Specify a separating string for multiple occurrences of <b>-o</b>. The default
+is an empty string. Separating strings are never coloured.
+</P>
+<P>
+<b>-q</b>, <b>--quiet</b>
+Work quietly, that is, display nothing except error messages. The exit
+status indicates whether or not any matches were found.
+</P>
+<P>
+<b>-r</b>, <b>--recursive</b>
+If any given path is a directory, recursively scan the files it contains,
+taking note of any <b>--include</b> and <b>--exclude</b> settings. By default, a
+directory is read as a normal file; in some operating systems this gives an
+immediate end-of-file. This option is a shorthand for setting the <b>-d</b>
+option to "recurse".
+</P>
+<P>
+<b>--recursion-limit</b>=<i>number</i>
+See <b>--match-limit</b> above.
+</P>
+<P>
+<b>-s</b>, <b>--no-messages</b>
+Suppress error messages about non-existent or unreadable files. Such files are
+quietly skipped. However, the return code is still 2, even if matches were
+found in other files.
+</P>
+<P>
+<b>-u</b>, <b>--utf-8</b>
+Operate in UTF-8 mode. This option is available only if PCRE2 has been compiled
+with UTF-8 support. All patterns (including those for any <b>--exclude</b> and
+<b>--include</b> options) and all subject lines that are scanned must be valid
+strings of UTF-8 characters.
+</P>
+<P>
+<b>-V</b>, <b>--version</b>
+Write the version numbers of <b>pcre2grep</b> and the PCRE2 library to the
+standard output and then exit. Anything else on the command line is
+ignored.
+</P>
+<P>
+<b>-v</b>, <b>--invert-match</b>
+Invert the sense of the match, so that lines which do <i>not</i> match any of
+the patterns are the ones that are found.
+</P>
+<P>
+<b>-w</b>, <b>--word-regex</b>, <b>--word-regexp</b>
+Force the patterns to match only whole words. This is equivalent to having \b
+at the start and end of the pattern. This option applies only to the patterns
+that are matched against the contents of files; it does not apply to patterns
+specified by any of the <b>--include</b> or <b>--exclude</b> options.
+</P>
+<P>
+<b>-x</b>, <b>--line-regex</b>, <b>--line-regexp</b>
+Force the patterns to be anchored (each must start matching at the beginning of
+a line) and in addition, require them to match entire lines. This is equivalent
+to having ^ and $ characters at the start and end of each alternative top-level
+branch in every pattern. This option applies only to the patterns that are
+matched against the contents of files; it does not apply to patterns specified
+by any of the <b>--include</b> or <b>--exclude</b> options.
+</P>
+<br><a name="SEC6" href="#TOC1">ENVIRONMENT VARIABLES</a><br>
+<P>
+The environment variables <b>LC_ALL</b> and <b>LC_CTYPE</b> are examined, in that
+order, for a locale. The first one that is set is used. This can be overridden
+by the <b>--locale</b> option. If no locale is set, the PCRE2 library's default
+(usually the "C" locale) is used.
+</P>
+<br><a name="SEC7" href="#TOC1">NEWLINES</a><br>
+<P>
+The <b>-N</b> (<b>--newline</b>) option allows <b>pcre2grep</b> to scan files with
+different newline conventions from the default. Any parts of the input files
+that are written to the standard output are copied identically, with whatever
+newline sequences they have in the input. However, the setting of this option
+does not affect the interpretation of files specified by the <b>-f</b>,
+<b>--exclude-from</b>, or <b>--include-from</b> options, which are assumed to use
+the operating system's standard newline sequence, nor does it affect the way in
+which <b>pcre2grep</b> writes informational messages to the standard error and
+output streams. For these it uses the string "\n" to indicate newlines,
+relying on the C I/O library to convert this to an appropriate sequence.
+</P>
+<br><a name="SEC8" href="#TOC1">OPTIONS COMPATIBILITY</a><br>
+<P>
+Many of the short and long forms of <b>pcre2grep</b>'s options are the same
+as in the GNU <b>grep</b> program. Any long option of the form
+<b>--xxx-regexp</b> (GNU terminology) is also available as <b>--xxx-regex</b>
+(PCRE2 terminology). However, the <b>--file-list</b>, <b>--file-offsets</b>,
+<b>--include-dir</b>, <b>--line-offsets</b>, <b>--locale</b>, <b>--match-limit</b>,
+<b>-M</b>, <b>--multiline</b>, <b>-N</b>, <b>--newline</b>, <b>--om-separator</b>,
+<b>--recursion-limit</b>, <b>-u</b>, and <b>--utf-8</b> options are specific to
+<b>pcre2grep</b>, as is the use of the <b>--only-matching</b> option with a
+capturing parentheses number.
+</P>
+<P>
+Although most of the common options work the same way, a few are different in
+<b>pcre2grep</b>. For example, the <b>--include</b> option's argument is a glob
+for GNU <b>grep</b>, but a regular expression for <b>pcre2grep</b>. If both the
+<b>-c</b> and <b>-l</b> options are given, GNU grep lists only file names,
+without counts, but <b>pcre2grep</b> gives the counts as well.
+</P>
+<br><a name="SEC9" href="#TOC1">OPTIONS WITH DATA</a><br>
+<P>
+There are four different ways in which an option with data can be specified.
+If a short form option is used, the data may follow immediately, or (with one
+exception) in the next command line item. For example:
+<pre>
+ -f/some/file
+ -f /some/file
+</pre>
+The exception is the <b>-o</b> option, which may appear with or without data.
+Because of this, if data is present, it must follow immediately in the same
+item, for example -o3.
+</P>
+<P>
+If a long form option is used, the data may appear in the same command line
+item, separated by an equals character, or (with two exceptions) it may appear
+in the next command line item. For example:
+<pre>
+ --file=/some/file
+ --file /some/file
+</pre>
+Note, however, that if you want to supply a file name beginning with ~ as data
+in a shell command, and have the shell expand ~ to a home directory, you must
+separate the file name from the option, because the shell does not treat ~
+specially unless it is at the start of an item.
+</P>
+<P>
+The exceptions to the above are the <b>--colour</b> (or <b>--color</b>) and
+<b>--only-matching</b> options, for which the data is optional. If one of these
+options does have data, it must be given in the first form, using an equals
+character. Otherwise <b>pcre2grep</b> will assume that it has no data.
+</P>
+<br><a name="SEC10" href="#TOC1">MATCHING ERRORS</a><br>
+<P>
+It is possible to supply a regular expression that takes a very long time to
+fail to match certain lines. Such patterns normally involve nested indefinite
+repeats, for example: (a+)*\d when matched against a line of a's with no final
+digit. The PCRE2 matching function has a resource limit that causes it to abort
+in these circumstances. If this happens, <b>pcre2grep</b> outputs an error
+message and the line that caused the problem to the standard error stream. If
+there are more than 20 such errors, <b>pcre2grep</b> gives up.
+</P>
+<P>
+The <b>--match-limit</b> option of <b>pcre2grep</b> can be used to set the
+overall resource limit; there is a second option called <b>--recursion-limit</b>
+that sets a limit on the amount of memory (usually stack) that is used (see the
+discussion of these options above).
+</P>
+<br><a name="SEC11" href="#TOC1">DIAGNOSTICS</a><br>
+<P>
+Exit status is 0 if any matches were found, 1 if no matches were found, and 2
+for syntax errors, overlong lines, non-existent or inaccessible files (even if
+matches were found in other files) or too many matching errors. Using the
+<b>-s</b> option to suppress error messages about inaccessible files does not
+affect the return code.

+<P>
+Just-in-time compiling is a heavyweight optimization that can greatly speed up
+pattern matching. However, it comes at the cost of extra processing before the
+match is performed, so it is of most benefit when the same pattern is going to
+be matched many times. This does not necessarily mean many calls of a matching
+function; if the pattern is not anchored, matching attempts may take place many
+times at various positions in the subject, even for a single call. Therefore,
+if the subject string is very long, it may still pay to use JIT even for
+one-off matches. JIT support is available for all of the 8-bit, 16-bit and
+32-bit PCRE2 libraries.
+</P>
+<P>
+JIT support applies only to the traditional Perl-compatible matching function.
+It does not apply when the DFA matching function is being used. The code for
+this support was written by Zoltan Herczeg.
+</P>
+<br><a name="SEC2" href="#TOC1">AVAILABILITY OF JIT SUPPORT</a><br>
+<P>
+JIT support is an optional feature of PCRE2. The "configure" option
+--enable-jit (or equivalent CMake option) must be set when PCRE2 is built if
+you want to use JIT. The support is limited to the following hardware
+platforms:
+<pre>

+If --enable-jit is set on an unsupported platform, compilation fails.
+</P>
+<P>
+A program can tell if JIT support is available by calling <b>pcre2_config()</b>
+with the PCRE2_CONFIG_JIT option. The result is 1 when JIT is available, and 0
+otherwise. However, a simple program does not need to check this in order to
+use JIT. The API is implemented in a way that falls back to the interpretive
+code if JIT is not available. For programs that need the best possible
+performance, there is also a "fast path" API that is JIT-specific.
+</P>
+<br><a name="SEC3" href="#TOC1">SIMPLE USE OF JIT</a><br>
+<P>
+To make use of the JIT support in the simplest way, all you have to do is to
+call <b>pcre2_jit_compile()</b> after successfully compiling a pattern with
+<b>pcre2_compile()</b>. This function has two arguments: the first is the
+compiled pattern pointer that was returned by <b>pcre2_compile()</b>, and the
+second is zero or more of the following option bits: PCRE2_JIT_COMPLETE,
+PCRE2_JIT_PARTIAL_HARD, or PCRE2_JIT_PARTIAL_SOFT.
+</P>
+<P>
+If JIT support is not available, a call to <b>pcre2_jit_compile()</b> does
+nothing and returns PCRE2_ERROR_JIT_BADOPTION. Otherwise, the compiled pattern
+is passed to the JIT compiler, which turns it into machine code that executes
+much faster than the normal interpretive code, but yields exactly the same
+results. The returned value from <b>pcre2_jit_compile()</b> is zero on success,
+or a negative error code.
+</P>
+<P>
+There is a limit to the size of pattern that JIT supports, imposed by the size
+of machine stack that it uses. The exact rules are not documented because they
+may change at any time, in particular, when new optimizations are introduced.
+If a pattern is too big, a call to \fBpcre2_jit_compile()\fB returns
+PCRE2_ERROR_NOMEMORY.
+</P>
+<P>
+PCRE2_JIT_COMPLETE requests the JIT compiler to generate code for complete
+matches. If you want to run partial matches using the PCRE2_PARTIAL_HARD or
+PCRE2_PARTIAL_SOFT options of <b>pcre2_match()</b>, you should set one or both
+of the other options as well as, or instead of PCRE2_JIT_COMPLETE. The JIT
+compiler generates different optimized code for each of the three modes
+(normal, soft partial, hard partial). When <b>pcre2_match()</b> is called, the
+appropriate code is run if it is available. Otherwise, the pattern is matched
+using interpretive code.
+</P>
+<P>
+You can call <b>pcre2_jit_compile()</b> multiple times for the same compiled
+pattern. It does nothing if it has previously compiled code for any of the
+option bits. For example, you can call it once with PCRE2_JIT_COMPLETE and
+(perhaps later, when you find you need partial matching) again with
+PCRE2_JIT_COMPLETE and PCRE2_JIT_PARTIAL_HARD. This time it will ignore
+PCRE2_JIT_COMPLETE and just compile code for partial matching. If
+<b>pcre2_jit_compile()</b> is called with no option bits set, it immediately
+returns zero. This is an alternative way of testing whether JIT is available.
+</P>
+<P>
+At present, it is not possible to free JIT compiled code except when the entire
+compiled pattern is freed by calling <b>pcre2_code_free()</b>.
+</P>
+<P>
+In some circumstances you may need to call additional functions. These are
+described in the section entitled
+<a href="#stackcontrol">"Controlling the JIT stack"</a>
+below.
+</P>
+<P>
+There are some <b>pcre2_match()</b> options that are not supported by JIT, and
+there are also some pattern items that JIT cannot handle. Details are given
+below. In both cases, matching automatically falls back to the interpretive
+code. If you want to know whether JIT was actually used for a particular match,
+you should arrange for a JIT callback function to be set up as described in the
+section entitled
+<a href="#stackcontrol">"Controlling the JIT stack"</a>
+below, even if you do not need to supply a non-default JIT stack. Such a
+callback function is called whenever JIT code is about to be obeyed. If the
+match-time options are not right for JIT execution, the callback function is
+not obeyed.
+</P>
+<P>
+If the JIT compiler finds an unsupported item, no JIT data is generated. You
+can find out if JIT matching is available after compiling a pattern by calling
+<b>pcre2_pattern_info()</b> with the PCRE2_INFO_JITSIZE option. A non-zero
+result means that JIT compilation was successful. A result of 0 means that JIT
+support is not available, or the pattern was not processed by
+<b>pcre2_jit_compile()</b>, or the JIT compiler was not able to handle the
+pattern.
+</P>
+<br><a name="SEC4" href="#TOC1">UNSUPPORTED OPTIONS AND PATTERN ITEMS</a><br>
+<P>
+The <b>pcre2_match()</b> options that are supported for JIT matching are
+PCRE2_NOTBOL, PCRE2_NOTEOL, PCRE2_NOTEMPTY, PCRE2_NOTEMPTY_ATSTART,
+PCRE2_NO_UTF_CHECK, PCRE2_PARTIAL_HARD, and PCRE2_PARTIAL_SOFT. The
+PCRE2_ANCHORED option is not supported at match time.
+</P>
+<P>
+The only unsupported pattern items are \C (match a single data unit) when
+running in a UTF mode, and a callout immediately before an assertion condition
+in a conditional group.
+</P>
+<br><a name="SEC5" href="#TOC1">RETURN VALUES FROM JIT MATCHING</a><br>
+<P>
+When a pattern is matched using JIT matching, the return values are the same
+as those given by the interpretive <b>pcre2_match()</b> code, with the addition
+of one new error code: PCRE2_ERROR_JIT_STACKLIMIT. This means that the memory
+used for the JIT stack was insufficient. See
+<a href="#stackcontrol">"Controlling the JIT stack"</a>
+below for a discussion of JIT stack usage.
+</P>
+<P>
+The error code PCRE2_ERROR_MATCHLIMIT is returned by the JIT code if searching
+a very large pattern tree goes on for too long, as it is in the same
+circumstance when JIT is not used, but the details of exactly what is counted
+are not the same. The PCRE2_ERROR_RECURSIONLIMIT error code is never returned
+when JIT matching is used.
+<a name="stackcontrol"></a></P>
+<br><a name="SEC6" href="#TOC1">CONTROLLING THE JIT STACK</a><br>
+<P>
+When the compiled JIT code runs, it needs a block of memory to use as a stack.
+By default, it uses 32K on the machine stack. However, some large or
+complicated patterns need more than this. The error PCRE2_ERROR_JIT_STACKLIMIT
+is given when there is not enough stack. Three functions are provided for
+managing blocks of memory for use as JIT stacks. There is further discussion
+about the use of JIT stacks in the section entitled
+<a href="#stackfaq">"JIT stack FAQ"</a>
+below.
+</P>
+<P>
+The <b>pcre2_jit_stack_create()</b> function creates a JIT stack. Its arguments
+are a starting size, a maximum size, and a general context (for memory
+allocation functions, or NULL for standard memory allocation). It returns a
+pointer to an opaque structure of type <b>pcre2_jit_stack</b>, or NULL if there
+is an error. The <b>pcre2_jit_stack_free()</b> function is used to free a stack
+that is no longer needed. (For the technically minded: the address space is
+allocated by mmap or VirtualAlloc.)
+</P>
+<P>
+JIT uses far less memory for recursion than the interpretive code,
+and a maximum stack size of 512K to 1M should be more than enough for any
+pattern.
+</P>
+<P>
+The <b>pcre2_jit_stack_assign()</b> function specifies which stack JIT code
+should use. Its arguments are as follows:
+<pre>
+ pcre2_match_context *mcontext
+ pcre2_jit_callback callback
+ void *data
+</pre>
+The first argument is a pointer to a match context. When this is subsequently
+passed to a matching function, its information determines which JIT stack is
+used. There are three cases for the values of the other two options:
+<pre>
+ (1) If <i>callback</i> is NULL and <i>data</i> is NULL, an internal 32K block
+ on the machine stack is used. This is the default when a match
+ context is created.
+
+ (2) If <i>callback</i> is NULL and <i>data</i> is not NULL, <i>data</i> must be
+ a pointer to a valid JIT stack, the result of calling
+ <b>pcre2_jit_stack_create()</b>.
+
+ (3) If <i>callback</i> is not NULL, it must point to a function that is
+ called with <i>data</i> as an argument at the start of matching, in
+ order to set up a JIT stack. If the return from the callback
+ function is NULL, the internal 32K stack is used; otherwise the
+ return value must be a valid JIT stack, the result of calling
+ <b>pcre2_jit_stack_create()</b>.
+</pre>
+A callback function is obeyed whenever JIT code is about to be run; it is not
+obeyed when <b>pcre2_match()</b> is called with options that are incompatible
+for JIT matching. A callback function can therefore be used to determine
+whether a match operation was executed by JIT or by the interpreter.
+</P>
+<P>
+You may safely use the same JIT stack for more than one pattern (either by
+assigning directly or by callback), as long as the patterns are matched
+sequentially in the same thread. Currently, the only way to set up
+non-sequential matches in one thread is to use callouts: if a callout function
+starts another match, that match must use a different JIT stack to the one used
+for currently suspended match(es).
+</P>
+<P>
+In a multithread application, if you do not
+specify a JIT stack, or if you assign or pass back NULL from a callback, that
+is thread-safe, because each thread has its own machine stack. However, if you
+assign or pass back a non-NULL JIT stack, this must be a different stack for
+each thread so that the application is thread-safe.
+</P>
+<P>
+Strictly speaking, even more is allowed. You can assign the same non-NULL stack
+to a match context that is used by any number of patterns, as long as they are
+not used for matching by multiple threads at the same time. For example, you
+could use the same stack in all compiled patterns, with a global mutex in the
+callback to wait until the stack is available for use. However, this is an
+inefficient solution, and not recommended.
+</P>
+<P>
+This is a suggestion for how a multithreaded program that needs to set up
+non-default JIT stacks might operate:
+<pre>
+ During thread initalization
+ thread_local_var = pcre2_jit_stack_create(...)
+
+ During thread exit
+ pcre2_jit_stack_free(thread_local_var)
+
+ Use a one-line callback function
+ return thread_local_var
+</pre>
+All the functions described in this section do nothing if JIT is not available.
+<a name="stackfaq"></a></P>
+<br><a name="SEC7" href="#TOC1">JIT STACK FAQ</a><br>
+<P>
+(1) Why do we need JIT stacks?
+<br>
+<br>
+PCRE2 (and JIT) is a recursive, depth-first engine, so it needs a stack where
+the local data of the current node is pushed before checking its child nodes.
+Allocating real machine stack on some platforms is difficult. For example, the
+stack chain needs to be updated every time if we extend the stack on PowerPC.
+Although it is possible, its updating time overhead decreases performance. So
+we do the recursion in memory.
+</P>
+<P>
+(2) Why don't we simply allocate blocks of memory with <b>malloc()</b>?
+<br>
+<br>
+Modern operating systems have a nice feature: they can reserve an address space
+instead of allocating memory. We can safely allocate memory pages inside this
+address space, so the stack could grow without moving memory data (this is
+important because of pointers). Thus we can allocate 1M address space, and use
+only a single memory page (usually 4K) if that is enough. However, we can still
+grow up to 1M anytime if needed.
+</P>
+<P>
+(3) Who "owns" a JIT stack?
+<br>
+<br>
+The owner of the stack is the user program, not the JIT studied pattern or
+anything else. The user program must ensure that if a stack is being used by
+<b>pcre2_match()</b>, (that is, it is assigned to a match context that is passed
+to the pattern currently running), that stack must not be used by any other
+threads (to avoid overwriting the same memory area). The best practice for
+multithreaded programs is to allocate a stack for each thread, and return this
+stack through the JIT callback function.
+</P>
+<P>
+(4) When should a JIT stack be freed?
+<br>
+<br>
+You can free a JIT stack at any time, as long as it will not be used by
+<b>pcre2_match()</b> again. When you assign the stack to a match context, only a
+pointer is set. There is no reference counting or any other magic. You can free
+compiled patterns, contexts, and stacks in any order, anytime. Just \fIdo
+not\fP call <b>pcre2_match()</b> with a match context pointing to an already
+freed stack, as that will cause SEGFAULT. (Also, do not free a stack currently
+used by <b>pcre2_match()</b> in another thread). You can also replace the stack
+in a context at any time when it is not in use. You should free the previous
+stack before assigning a replacement.
+</P>
+<P>
+(5) Should I allocate/free a stack every time before/after calling
+<b>pcre2_match()</b>?
+<br>
+<br>
+No, because this is too costly in terms of resources. However, you could
+implement some clever idea which release the stack if it is not used in let's
+say two minutes. The JIT callback can help to achieve this without keeping a
+list of patterns.
+</P>
+<P>
+(6) OK, the stack is for long term memory allocation. But what happens if a
+pattern causes stack overflow with a stack of 1M? Is that 1M kept until the
+stack is freed?
+<br>
+<br>
+Especially on embedded sytems, it might be a good idea to release memory
+sometimes without freeing the stack. There is no API for this at the moment.
+Probably a function call which returns with the currently allocated memory for
+any stack and another which allows releasing memory (shrinking the stack) would
+be a good idea if someone needs this.
+</P>
+<P>
+(7) This is too much of a headache. Isn't there any better solution for JIT
+stack handling?
+<br>
+<br>
+No, thanks to Windows. If POSIX threads were used everywhere, we could throw
+out this complicated API.
+</P>
+<br><a name="SEC8" href="#TOC1">FREEING JIT SPECULATIVE MEMORY</a><br>
+<P>
+<b>void pcre2_jit_free_unused_memory(pcre2_general_context *<i>gcontext</i>);</b>
+</P>
+<P>
+The JIT executable allocator does not free all memory when it is possible.
+It expects new allocations, and keeps some free memory around to improve
+allocation speed. However, in low memory conditions, it might be better to free
+all possible memory. You can cause this to happen by calling
+pcre2_jit_free_unused_memory(). Its argument is a general context, for custom
+memory management, or NULL for standard memory management.
+</P>
+<br><a name="SEC9" href="#TOC1">EXAMPLE CODE</a><br>
+<P>
+This is a single-threaded example that specifies a JIT stack without using a
+callback. A real program should include error checking after all the function
+calls.
+<pre>
+ int rc;
+ pcre2_code *re;
+ pcre2_match_data *match_data;
+ pcre2_match_context *mcontext;
+ pcre2_jit_stack *jit_stack;
+
+ re = pcre2_compile(pattern, PCRE2_ZERO_TERMINATED, 0,
+ &errornumber, &erroffset, NULL);

+ pcre2_match_data_free(match_data);
+ pcre2_match_context_free(mcontext);
+ pcre2_jit_stack_free(jit_stack);
+
+</PRE>
+</P>
+<br><a name="SEC10" href="#TOC1">JIT FAST PATH API</a><br>
+<P>
+Because the API described above falls back to interpreted matching when JIT is
+not available, it is convenient for programs that are written for general use
+in many environments. However, calling JIT via <b>pcre2_match()</b> does have a
+performance impact. Programs that are written for use where JIT is known to be
+available, and which need the best possible performance, can instead use a
+"fast path" API to call JIT matching directly instead of calling
+<b>pcre2_match()</b> (obviously only for patterns that have been successfully
+processed by <b>pcre2_jit_compile()</b>).
+</P>
+<P>
+The fast path function is called <b>pcre2_jit_match()</b>, and it takes exactly
+the same arguments as <b>pcre2_match()</b>. The return values are also the same,
+plus PCRE2_ERROR_JIT_BADOPTION if a matching mode (partial or complete) is
+requested that was not compiled. Unsupported option bits (for example,
+PCRE2_ANCHORED) are ignored.
+</P>
+<P>
+When you call <b>pcre2_match()</b>, as well as testing for invalid options, a
+number of other sanity checks are performed on the arguments. For example, if
+the subject pointer is NULL, an immediate error is given. Also, unless
+PCRE2_NO_UTF_CHECK is set, a UTF subject string is tested for validity. In the
+interests of speed, these checks do not happen on the JIT fast path, and if
+invalid data is passed, the result is undefined.
+</P>
+<P>
+Bypassing the sanity checks and the <b>pcre2_match()</b> wrapping can give
+speedups of more than 10%.

+SIZE AND OTHER LIMITATIONS
+</b><br>
+<P>
+There are some size limitations in PCRE2 but it is hoped that they will never
+in practice be relevant.
+</P>
+<P>
+The maximum size of a compiled pattern is approximately 64K code units for the
+8-bit and 16-bit libraries if PCRE2 is compiled with the default internal
+linkage size, which is 2 bytes for these libraries. If you want to process
+regular expressions that are truly enormous, you can compile PCRE2 with an
+internal linkage size of 3 or 4 (when building the 16-bit library, 3 is rounded
+up to 4). See the <b>README</b> file in the source distribution and the
+<a href="pcre2build.html"><b>pcre2build</b></a>
+documentation for details. In these cases the limit is substantially larger.
+However, the speed of execution is slower. In the 32-bit library, the internal
+linkage size is always 4.
+</P>
+<P>
+The maximum length of a source pattern string is essentially unlimited; it is
+the largest number a PCRE2_SIZE variable can hold. However, the program that
+calls <b>pcre2_compile()</b> can specify a smaller limit.
+</P>
+<P>
+The maximum length (in code units) of a subject string is one less than the
+largest number a PCRE2_SIZE variable can hold. PCRE2_SIZE is an unsigned
+integer type, usually defined as size_t. Its maximum value (that is
+~(PCRE2_SIZE)0) is reserved as a special indicator for zero-terminated strings
+and unset offsets.
+</P>
+<P>
+Note that when using the traditional matching function, PCRE2 uses recursion to
+handle subpatterns and indefinite repetition. This means that the available
+stack space may limit the size of a subject string that can be processed by
+certain patterns. For a discussion of stack issues, see the
+<a href="pcre2stack.html"><b>pcre2stack</b></a>
+documentation.
+</P>
+<P>
+All values in repeating quantifiers must be less than 65536.
+</P>
+<P>
+The maximum length of a lookbehind assertion is 65535 characters.
+</P>
+<P>
+There is no limit to the number of parenthesized subpatterns, but there can be
+no more than 65535 capturing subpatterns. There is, however, a limit to the
+depth of nesting of parenthesized subpatterns of all kinds. This is imposed in
+order to limit the amount of system stack used at compile time. The limit can
+be specified when PCRE2 is built; the default is 250.
+</P>
+<P>
+There is a limit to the number of forward references to subsequent subpatterns
+of around 200,000. Repeated forward references with fixed upper limits, for
+example, (?2){0,100} when subpattern number 2 is to the right, are included in
+the count. There is no limit to the number of backward references.
+</P>
+<P>
+The maximum length of name for a named subpattern is 32 code units, and the
+maximum number of named subpatterns is 10000.
+</P>
+<P>
+The maximum length of a name in a (*MARK), (*PRUNE), (*SKIP), or (*THEN) verb
+is 255 for the 8-bit library and 65535 for the 16-bit and 32-bit libraries.

+<P>
+This document describes the two different algorithms that are available in
+PCRE2 for matching a compiled regular expression against a given subject
+string. The "standard" algorithm is the one provided by the <b>pcre2_match()</b>
+function. This works in the same as as Perl's matching function, and provide a
+Perl-compatible matching operation. The just-in-time (JIT) optimization that is
+described in the
+<a href="pcre2jit.html"><b>pcre2jit</b></a>
+documentation is compatible with this function.
+</P>
+<P>
+An alternative algorithm is provided by the <b>pcre2_dfa_match()</b> function;
+it operates in a different way, and is not Perl-compatible. This alternative
+has advantages and disadvantages compared with the standard algorithm, and
+these are described below.
+</P>
+<P>
+When there is only one possible way in which a given subject string can match a
+pattern, the two algorithms give the same answer. A difference arises, however,
+when there are multiple possibilities. For example, if the pattern
+<pre>
+ ^<.*>
+</pre>
+is matched against the string
+<pre>
+ <something> <something else> <something further>
+</pre>
+there are three possible answers. The standard algorithm finds only one of
+them, whereas the alternative algorithm finds all three.
+</P>
+<br><a name="SEC2" href="#TOC1">REGULAR EXPRESSIONS AS TREES</a><br>
+<P>
+The set of strings that are matched by a regular expression can be represented
+as a tree structure. An unlimited repetition in the pattern makes the tree of
+infinite size, but it is still a tree. Matching the pattern to a given subject
+string (from a given starting point) can be thought of as a search of the tree.
+There are two ways to search a tree: depth-first and breadth-first, and these
+correspond to the two matching algorithms provided by PCRE2.
+</P>
+<br><a name="SEC3" href="#TOC1">THE STANDARD MATCHING ALGORITHM</a><br>
+<P>
+In the terminology of Jeffrey Friedl's book "Mastering Regular Expressions",
+the standard algorithm is an "NFA algorithm". It conducts a depth-first search
+of the pattern tree. That is, it proceeds along a single path through the tree,
+checking that the subject matches what is required. When there is a mismatch,
+the algorithm tries any alternatives at the current point, and if they all
+fail, it backs up to the previous branch point in the tree, and tries the next
+alternative branch at that level. This often involves backing up (moving to the
+left) in the subject string as well. The order in which repetition branches are
+tried is controlled by the greedy or ungreedy nature of the quantifier.
+</P>
+<P>
+If a leaf node is reached, a matching string has been found, and at that point
+the algorithm stops. Thus, if there is more than one possible match, this
+algorithm returns the first one that it finds. Whether this is the shortest,
+the longest, or some intermediate length depends on the way the greedy and
+ungreedy repetition quantifiers are specified in the pattern.
+</P>
+<P>
+Because it ends up with a single path through the tree, it is relatively
+straightforward for this algorithm to keep track of the substrings that are
+matched by portions of the pattern in parentheses. This provides support for
+capturing parentheses and back references.
+</P>
+<br><a name="SEC4" href="#TOC1">THE ALTERNATIVE MATCHING ALGORITHM</a><br>
+<P>
+This algorithm conducts a breadth-first search of the tree. Starting from the
+first matching point in the subject, it scans the subject string from left to
+right, once, character by character, and as it does this, it remembers all the
+paths through the tree that represent valid matches. In Friedl's terminology,
+this is a kind of "DFA algorithm", though it is not implemented as a
+traditional finite state machine (it keeps multiple states active
+simultaneously).
+</P>
+<P>
+Although the general principle of this matching algorithm is that it scans the
+subject string only once, without backtracking, there is one exception: when a
+lookaround assertion is encountered, the characters following or preceding the
+current point have to be independently inspected.
+</P>
+<P>
+The scan continues until either the end of the subject is reached, or there are
+no more unterminated paths. At this point, terminated paths represent the
+different matching possibilities (if there are none, the match has failed).
+Thus, if there is more than one possible match, this algorithm finds all of
+them, and in particular, it finds the longest. The matches are returned in
+decreasing order of length. There is an option to stop the algorithm after the
+first match (which is necessarily the shortest) is found.
+</P>
+<P>
+Note that all the matches that are found start at the same point in the
+subject. If the pattern
+<pre>
+ cat(er(pillar)?)?
+</pre>
+is matched against the string "the caterpillar catchment", the result is the
+three strings "caterpillar", "cater", and "cat" that start at the fifth
+character of the subject. The algorithm does not automatically move on to find
+matches that start at later positions.
+</P>
+<P>
+PCRE2's "auto-possessification" optimization usually applies to character
+repeats at the end of a pattern (as well as internally). For example, the
+pattern "a\d+" is compiled as if it were "a\d++" because there is no point
+even considering the possibility of backtracking into the repeated digits. For
+DFA matching, this means that only one possible match is found. If you really
+do want multiple matches in such cases, either use an ungreedy repeat
+("a\d+?") or set the PCRE2_NO_AUTO_POSSESS option when compiling.
+</P>
+<P>
+There are a number of features of PCRE2 regular expressions that are not
+supported by the alternative matching algorithm. They are as follows:
+</P>
+<P>
+1. Because the algorithm finds all possible matches, the greedy or ungreedy
+nature of repetition quantifiers is not relevant (though it may affect
+auto-possessification, as just described). During matching, greedy and ungreedy
+quantifiers are treated in exactly the same way. However, possessive
+quantifiers can make a difference when what follows could also match what is
+quantified, for example in a pattern like this:
+<pre>
+ ^a++\w!
+</pre>
+This pattern matches "aaab!" but not "aaa!", which would be matched by a
+non-possessive quantifier. Similarly, if an atomic group is present, it is
+matched as if it were a standalone pattern at the current point, and the
+longest match is then "locked in" for the rest of the overall pattern.
+</P>
+<P>
+2. When dealing with multiple paths through the tree simultaneously, it is not
+straightforward to keep track of captured substrings for the different matching
+possibilities, and PCRE2's implementation of this algorithm does not attempt to
+do this. This means that no captured substrings are available.
+</P>
+<P>
+3. Because no substrings are captured, back references within the pattern are
+not supported, and cause errors if encountered.
+</P>
+<P>
+4. For the same reason, conditional expressions that use a backreference as the
+condition or test for a specific group recursion are not supported.
+</P>
+<P>
+5. Because many paths through the tree may be active, the \K escape sequence,
+which resets the start of the match when encountered (but may be on some paths
+and not on others), is not supported. It causes an error if encountered.
+</P>
+<P>
+6. Callouts are supported, but the value of the <i>capture_top</i> field is
+always 1, and the value of the <i>capture_last</i> field is always 0.
+</P>
+<P>
+7. The \C escape sequence, which (in the standard algorithm) always matches a
+single code unit, even in a UTF mode, is not supported in these modes, because
+the alternative algorithm moves through the subject string one character (not
+code unit) at a time, for all active paths through the tree.
+</P>
+<P>
+8. Except for (*FAIL), the backtracking control verbs such as (*PRUNE) are not
+supported. (*FAIL) is supported, and behaves like a failing negative assertion.
+</P>
+<br><a name="SEC5" href="#TOC1">ADVANTAGES OF THE ALTERNATIVE ALGORITHM</a><br>
+<P>
+Using the alternative matching algorithm provides the following advantages:
+</P>
+<P>
+1. All possible matches (at a single point in the subject) are automatically
+found, and in particular, the longest match is found. To find more than one
+match using the standard algorithm, you have to do kludgy things with
+callouts.
+</P>
+<P>
+2. Because the alternative algorithm scans the subject string just once, and
+never needs to backtrack (except for lookbehinds), it is possible to pass very
+long subject strings to the matching function in several pieces, checking for
+partial matching each time. Although it is also possible to do multi-segment
+matching using the standard algorithm, by retaining partially matched
+substrings, it is more complicated. The
+<a href="pcre2partial.html"><b>pcre2partial</b></a>
+documentation gives details of partial matching and discusses multi-segment
+matching.
+</P>
+<br><a name="SEC6" href="#TOC1">DISADVANTAGES OF THE ALTERNATIVE ALGORITHM</a><br>
+<P>
+The alternative algorithm suffers from a number of disadvantages:
+</P>
+<P>
+1. It is substantially slower than the standard algorithm. This is partly
+because it has to search for all possible matches, but is also because it is
+less susceptible to optimization.
+</P>
+<P>
+2. Capturing parentheses and back references are not supported.
+</P>
+<P>
+3. Although atomic groups are supported, their use does not provide the
+performance advantage that it does for the standard algorithm.

+<P>
+In normal use of PCRE2, if the subject string that is passed to a matching
+function matches as far as it goes, but is too short to match the entire
+pattern, PCRE2_ERROR_NOMATCH is returned. There are circumstances where it
+might be helpful to distinguish this case from other cases in which there is no
+match.
+</P>
+<P>
+Consider, for example, an application where a human is required to type in data
+for a field with specific formatting requirements. An example might be a date
+in the form <i>ddmmmyy</i>, defined by this pattern:
+<pre>
+ ^\d?\d(jan|feb|mar|apr|may|jun|jul|aug|sep|oct|nov|dec)\d\d$
+</pre>
+If the application sees the user's keystrokes one by one, and can check that
+what has been typed so far is potentially valid, it is able to raise an error
+as soon as a mistake is made, by beeping and not reflecting the character that
+has been typed, for example. This immediate feedback is likely to be a better
+user interface than a check that is delayed until the entire string has been
+entered. Partial matching can also be useful when the subject string is very
+long and is not all available at once.
+</P>
+<P>
+PCRE2 supports partial matching by means of the PCRE2_PARTIAL_SOFT and
+PCRE2_PARTIAL_HARD options, which can be set when calling a matching function.
+The difference between the two options is whether or not a partial match is
+preferred to an alternative complete match, though the details differ between
+the two types of matching function. If both options are set, PCRE2_PARTIAL_HARD
+takes precedence.
+</P>
+<P>
+If you want to use partial matching with just-in-time optimized code, you must
+call <b>pcre2_jit_compile()</b> with one or both of these options:
+<pre>
+ PCRE2_JIT_PARTIAL_SOFT
+ PCRE2_JIT_PARTIAL_HARD
+</pre>
+PCRE2_JIT_COMPLETE should also be set if you are going to run non-partial
+matches on the same pattern. If the appropriate JIT mode has not been compiled,
+interpretive matching code is used.
+</P>
+<P>
+Setting a partial matching option disables two of PCRE2's standard
+optimizations. PCRE2 remembers the last literal code unit in a pattern, and
+abandons matching immediately if it is not present in the subject string. This
+optimization cannot be used for a subject string that might match only
+partially. PCRE2 also knows the minimum length of a matching string, and does
+not bother to run the matching function on shorter strings. This optimization
+is also disabled for partial matching.
+</P>
+<br><a name="SEC2" href="#TOC1">PARTIAL MATCHING USING pcre2_match()</a><br>
+<P>
+A partial match occurs during a call to <b>pcre2_match()</b> when the end of the
+subject string is reached successfully, but matching cannot continue because
+more characters are needed. However, at least one character in the subject must
+have been inspected. This character need not form part of the final matched
+string; lookbehind assertions and the \K escape sequence provide ways of
+inspecting characters before the start of a matched string. The requirement for
+inspecting at least one character exists because an empty string can always be
+matched; without such a restriction there would always be a partial match of an
+empty string at the end of the subject.
+</P>
+<P>
+When a partial match is returned, the first two elements in the ovector point
+to the portion of the subject that was matched, but the values in the rest of
+the ovector are undefined. The appearance of \K in the pattern has no effect
+for a partial match. Consider this pattern:
+<pre>
+ /abc\K123/
+</pre>
+If it is matched against "456abc123xyz" the result is a complete match, and the
+ovector defines the matched string as "123", because \K resets the "start of
+match" point. However, if a partial match is requested and the subject string
+is "456abc12", a partial match is found for the string "abc12", because all
+these characters are needed for a subsequent re-match with additional
+characters.
+</P>
+<P>
+What happens when a partial match is identified depends on which of the two
+partial matching options are set.
+</P>
+<br><b>
+PCRE2_PARTIAL_SOFT WITH pcre2_match()
+</b><br>
+<P>
+If PCRE2_PARTIAL_SOFT is set when <b>pcre2_match()</b> identifies a partial
+match, the partial match is remembered, but matching continues as normal, and
+other alternatives in the pattern are tried. If no complete match can be found,
+PCRE2_ERROR_PARTIAL is returned instead of PCRE2_ERROR_NOMATCH.
+</P>
+<P>
+This option is "soft" because it prefers a complete match over a partial match.
+All the various matching items in a pattern behave as if the subject string is
+potentially complete. For example, \z, \Z, and $ match at the end of the
+subject, as normal, and for \b and \B the end of the subject is treated as a
+non-alphanumeric.
+</P>
+<P>
+If there is more than one partial match, the first one that was found provides
+the data that is returned. Consider this pattern:
+<pre>
+ /123\w+X|dogY/
+</pre>
+If this is matched against the subject string "abc123dog", both
+alternatives fail to match, but the end of the subject is reached during
+matching, so PCRE2_ERROR_PARTIAL is returned. The offsets are set to 3 and 9,
+identifying "123dog" as the first partial match that was found. (In this
+example, there are two partial matches, because "dog" on its own partially
+matches the second alternative.)
+</P>
+<br><b>
+PCRE2_PARTIAL_HARD WITH pcre2_match()
+</b><br>
+<P>
+If PCRE2_PARTIAL_HARD is set for <b>pcre2_match()</b>, PCRE2_ERROR_PARTIAL is
+returned as soon as a partial match is found, without continuing to search for
+possible complete matches. This option is "hard" because it prefers an earlier
+partial match over a later complete match. For this reason, the assumption is
+made that the end of the supplied subject string may not be the true end of the
+available data, and so, if \z, \Z, \b, \B, or $ are encountered at the end
+of the subject, the result is PCRE2_ERROR_PARTIAL, provided that at least one
+character in the subject has been inspected.
+</P>
+<br><b>
+Comparing hard and soft partial matching
+</b><br>
+<P>
+The difference between the two partial matching options can be illustrated by a
+pattern such as:
+<pre>
+ /dog(sbody)?/
+</pre>
+This matches either "dog" or "dogsbody", greedily (that is, it prefers the
+longer string if possible). If it is matched against the string "dog" with
+PCRE2_PARTIAL_SOFT, it yields a complete match for "dog". However, if
+PCRE2_PARTIAL_HARD is set, the result is PCRE2_ERROR_PARTIAL. On the other
+hand, if the pattern is made ungreedy the result is different:
+<pre>
+ /dog(sbody)??/
+</pre>
+In this case the result is always a complete match because that is found first,
+and matching never continues after finding a complete match. It might be easier
+to follow this explanation by thinking of the two patterns like this:
+<pre>
+ /dog(sbody)?/ is the same as /dogsbody|dog/
+ /dog(sbody)??/ is the same as /dog|dogsbody/
+</pre>
+The second pattern will never match "dogsbody", because it will always find the
+shorter match first.
+</P>
+<br><a name="SEC3" href="#TOC1">PARTIAL MATCHING USING pcre2_dfa_match()</a><br>
+<P>
+The DFA functions move along the subject string character by character, without
+backtracking, searching for all possible matches simultaneously. If the end of
+the subject is reached before the end of the pattern, there is the possibility
+of a partial match, again provided that at least one character has been
+inspected.
+</P>
+<P>
+When PCRE2_PARTIAL_SOFT is set, PCRE2_ERROR_PARTIAL is returned only if there
+have been no complete matches. Otherwise, the complete matches are returned.
+However, if PCRE2_PARTIAL_HARD is set, a partial match takes precedence over
+any complete matches. The portion of the string that was matched when the
+longest partial match was found is set as the first matching string.
+</P>
+<P>
+Because the DFA functions always search for all possible matches, and there is
+no difference between greedy and ungreedy repetition, their behaviour is
+different from the standard functions when PCRE2_PARTIAL_HARD is set. Consider
+the string "dog" matched against the ungreedy pattern shown above:
+<pre>
+ /dog(sbody)??/
+</pre>
+Whereas the standard function stops as soon as it finds the complete match for
+"dog", the DFA function also finds the partial match for "dogsbody", and so
+returns that when PCRE2_PARTIAL_HARD is set.
+</P>
+<br><a name="SEC4" href="#TOC1">PARTIAL MATCHING AND WORD BOUNDARIES</a><br>
+<P>
+If a pattern ends with one of sequences \b or \B, which test for word
+boundaries, partial matching with PCRE2_PARTIAL_SOFT can give counter-intuitive
+results. Consider this pattern:
+<pre>
+ /\bcat\b/
+</pre>
+This matches "cat", provided there is a word boundary at either end. If the
+subject string is "the cat", the comparison of the final "t" with a following
+character cannot take place, so a partial match is found. However, normal
+matching carries on, and \b matches at the end of the subject when the last
+character is a letter, so a complete match is found. The result, therefore, is
+<i>not</i> PCRE2_ERROR_PARTIAL. Using PCRE2_PARTIAL_HARD in this case does yield
+PCRE2_ERROR_PARTIAL, because then the partial match takes precedence.
+</P>
+<br><a name="SEC5" href="#TOC1">EXAMPLE OF PARTIAL MATCHING USING PCRE2TEST</a><br>
+<P>
+If the <b>partial_soft</b> (or <b>ps</b>) modifier is present on a
+<b>pcre2test</b> data line, the PCRE2_PARTIAL_SOFT option is used for the match.
+Here is a run of <b>pcre2test</b> that uses the date example quoted above:
+<pre>
+ re> /^\d?\d(jan|feb|mar|apr|may|jun|jul|aug|sep|oct|nov|dec)\d\d$/
+ data> 25jun04\=ps
+ 0: 25jun04
+ 1: jun
+ data> 25dec3\=ps
+ Partial match: 23dec3
+ data> 3ju\=ps
+ Partial match: 3ju
+ data> 3juj\=ps
+ No match
+ data> j\=ps
+ No match
+</pre>
+The first data string is matched completely, so <b>pcre2test</b> shows the
+matched substrings. The remaining four strings do not match the complete
+pattern, but the first two are partial matches. Similar output is obtained
+if DFA matching is used.
+</P>
+<P>
+If the <b>partial_hard</b> (or <b>ph</b>) modifier is present on a
+<b>pcre2test</b> data line, the PCRE2_PARTIAL_HARD option is set for the match.
+</P>
+<br><a name="SEC6" href="#TOC1">MULTI-SEGMENT MATCHING WITH pcre2_dfa_match()</a><br>
+<P>
+When a partial match has been found using a DFA matching function, it is
+possible to continue the match by providing additional subject data and calling
+the function again with the same compiled regular expression, this time setting
+the PCRE2_DFA_RESTART option. You must pass the same working space as before,
+because this is where details of the previous partial match are stored. Here is
+an example using <b>pcre2test</b>:
+<pre>
+ re> /^\d?\d(jan|feb|mar|apr|may|jun|jul|aug|sep|oct|nov|dec)\d\d$/
+ data> 23ja\=dfa,ps
+ Partial match: 23ja
+ data> n05\=dfa,dfa_restart
+ 0: n05
+</pre>
+The first call has "23ja" as the subject, and requests partial matching; the
+second call has "n05" as the subject for the continued (restarted) match.
+Notice that when the match is complete, only the last part is shown; PCRE2 does
+not retain the previously partially-matched string. It is up to the calling
+program to do that if it needs to.
+</P>
+<P>
+That means that, for an unanchored pattern, if a continued match fails, it is
+not possible to try again at a new starting point. All this facility is capable
+of doing is continuing with the previous match attempt. In the previous
+example, if the second set of data is "ug23" the result is no match, even
+though there would be a match for "aug23" if the entire string were given at
+once. Depending on the application, this may or may not be what you want.
+The only way to allow for starting again at the next character is to retain the
+matched part of the subject and try a new complete match.
+</P>
+<P>
+You can set the PCRE2_PARTIAL_SOFT or PCRE2_PARTIAL_HARD options with
+PCRE2_DFA_RESTART to continue partial matching over multiple segments. This
+facility can be used to pass very long subject strings to the DFA matching
+functions.
+</P>
+<br><a name="SEC7" href="#TOC1">MULTI-SEGMENT MATCHING WITH pcre2_match()</a><br>
+<P>
+Unlike the DFA function, it is not possible to restart the previous match with
+a new segment of data when using <b>pcre2_match()</b>. Instead, new data must be
+added to the previous subject string, and the entire match re-run, starting
+from the point where the partial match occurred. Earlier data can be discarded.
+</P>
+<P>
+It is best to use PCRE2_PARTIAL_HARD in this situation, because it does not
+treat the end of a segment as the end of the subject when matching \z, \Z,
+\b, \B, and $. Consider an unanchored pattern that matches dates:
+<pre>
+ re> /\d?\d(jan|feb|mar|apr|may|jun|jul|aug|sep|oct|nov|dec)\d\d/
+ data> The date is 23ja\=ph
+ Partial match: 23ja
+</pre>
+At this stage, an application could discard the text preceding "23ja", add on
+text from the next segment, and call the matching function again. Unlike the
+DFA matching function, the entire matching string must always be available,
+and the complete matching process occurs for each call, so more memory and more
+processing time is needed.
+</P>
+<br><a name="SEC8" href="#TOC1">ISSUES WITH MULTI-SEGMENT MATCHING</a><br>
+<P>
+Certain types of pattern may give problems with multi-segment matching,
+whichever matching function is used.
+</P>
+<P>
+1. If the pattern contains a test for the beginning of a line, you need to pass
+the PCRE2_NOTBOL option when the subject string for any call does start at the
+beginning of a line. There is also a PCRE2_NOTEOL option, but in practice when
+doing multi-segment matching you should be using PCRE2_PARTIAL_HARD, which
+includes the effect of PCRE2_NOTEOL.
+</P>
+<P>
+2. If a pattern contains a lookbehind assertion, characters that precede the
+start of the partial match may have been inspected during the matching process.
+When using <b>pcre2_match()</b>, sufficient characters must be retained for the
+next match attempt. You can ensure that enough characters are retained by doing
+the following:
+</P>
+<P>
+Before doing any matching, find the length of the longest lookbehind in the
+pattern by calling <b>pcre2_pattern_info()</b> with the PCRE2_INFO_MAXLOOKBEHIND
+option. Note that the resulting count is in characters, not code units. After a
+partial match, moving back from the ovector[0] offset in the subject by the
+number of characters given for the maximum lookbehind gets you to the earliest
+character that must be retained. In a non-UTF or a 32-bit situation, moving
+back is just a subtraction, but in UTF-8 or UTF-16 you have to count characters
+while moving back through the code units.
+</P>
+<P>
+Characters before the point you have now reached can be discarded, and after
+the next segment has been added to what is retained, you should run the next
+match with the <b>startoffset</b> argument set so that the match begins at the
+same point as before.
+</P>
+<P>
+For example, if the pattern "(?<=123)abc" is partially matched against the
+string "xx123ab", the ovector offsets are 5 and 7 ("ab"). The maximum
+lookbehind count is 3, so all characters before offset 2 can be discarded. The
+value of <b>startoffset</b> for the next match should be 3. When <b>pcre2test</b>
+displays a partial match, it indicates the lookbehind characters with '<'
+characters:
+<pre>
+ re> "(?<=123)abc"
+ data> xx123ab\=ph
+ Partial match: 123ab
+ <<<
+</PRE>
+</P>
+<P>
+3. Because a partial match must always contain at least one character, what
+might be considered a partial match of an empty string actually gives a "no
+match" result. For example:
+<pre>
+ re> /c(?<=abc)x/
+ data> ab\=ps
+ No match
+</pre>
+If the next segment begins "cx", a match should be found, but this will only
+happen if characters from the previous segment are retained. For this reason, a
+"no match" result should be interpreted as "partial match of an empty string"
+when the pattern contains lookbehinds.
+</P>
+<P>
+4. Matching a subject string that is split into multiple segments may not
+always produce exactly the same result as matching over one single long string,
+especially when PCRE2_PARTIAL_SOFT is used. The section "Partial Matching and
+Word Boundaries" above describes an issue that arises if the pattern ends with
+\b or \B. Another kind of difference may occur when there are multiple
+matching possibilities, because (for PCRE2_PARTIAL_SOFT) a partial match result
+is given only when there are no completed matches. This means that as soon as
+the shortest match has been found, continuation to a new subject segment is no
+longer possible. Consider this <b>pcre2test</b> example:
+<pre>
+ re> /dog(sbody)?/
+ data> dogsb\=ps
+ 0: dog
+ data> do\=ps,dfa
+ Partial match: do
+ data> gsb\=ps,dfa,dfa_restart
+ 0: g
+ data> dogsbody\=dfa
+ 0: dogsbody
+ 1: dog
+</pre>
+The first data line passes the string "dogsb" to a standard matching function,
+setting the PCRE2_PARTIAL_SOFT option. Although the string is a partial match
+for "dogsbody", the result is not PCRE2_ERROR_PARTIAL, because the shorter
+string "dog" is a complete match. Similarly, when the subject is presented to
+a DFA matching function in several parts ("do" and "gsb" being the first two)
+the match stops when "dog" has been found, and it is not possible to continue.
+On the other hand, if "dogsbody" is presented as a single string, a DFA
+matching function finds both matches.
+</P>
+<P>
+Because of these problems, it is best to use PCRE2_PARTIAL_HARD when matching
+multi-segment data. The example above then behaves differently:
+<pre>
+ re> /dog(sbody)?/
+ data> dogsb\=ph
+ Partial match: dogsb
+ data> do\=ps,dfa
+ Partial match: do
+ data> gsb\=ph,dfa,dfa_restart
+ Partial match: gsb
+</pre>
+5. Patterns that contain alternatives at the top level which do not all start
+with the same pattern item may not work as expected when PCRE2_DFA_RESTART is
+used. For example, consider this pattern:
+<pre>
+ 1234|3789
+</pre>
+If the first part of the subject is "ABC123", a partial match of the first
+alternative is found at offset 3. There is no partial match for the second
+alternative, because such a match does not start at the same point in the
+subject string. Attempting to continue with the string "7890" does not yield a
+match because only those alternatives that match at one point in the subject
+are remembered. The problem arises because the start of the second alternative
+matches within the first alternative. There is no problem with anchored
+patterns or patterns such as:
+<pre>
+ 1234|ABCD
+</pre>
+where no string can be a partial match for both alternatives. This is not a
+problem if a standard matching function is used, because the entire match has
+to be rerun each time:
+<pre>
+ re> /1234|3789/
+ data> ABC123\=ph
+ Partial match: 123
+ data> 1237890
+ 0: 3789
+</pre>
+Of course, instead of using PCRE2_DFA_RESTART, the same technique of re-running
+the entire match can also be used with the DFA matching function. Another
+possibility is to work with two buffers. If a partial match at offset <i>n</i>
+in the first buffer is followed by "no match" when PCRE2_DFA_RESTART is used on
+the second buffer, you can then try a new match starting at offset <i>n+1</i> in
+the first buffer.

+<br><a name="SEC1" href="#TOC1">PCRE2 REGULAR EXPRESSION DETAILS</a><br>
+<P>
+The syntax and semantics of the regular expressions that are supported by PCRE2
+are described in detail below. There is a quick-reference syntax summary in the
+<a href="pcre2syntax.html"><b>pcre2syntax</b></a>
+page. PCRE2 tries to match Perl syntax and semantics as closely as it can.
+PCRE2 also supports some alternative regular expression syntax (which does not
+conflict with the Perl syntax) in order to provide some compatibility with
+regular expressions in Python, .NET, and Oniguruma.
+</P>
+<P>
+Perl's regular expressions are described in its own documentation, and regular
+expressions in general are covered in a number of books, some of which have
+copious examples. Jeffrey Friedl's "Mastering Regular Expressions", published
+by O'Reilly, covers regular expressions in great detail. This description of
+PCRE2's regular expressions is intended as reference material.
+</P>
+<P>
+This document discusses the patterns that are supported by PCRE2 when its main
+matching function, <b>pcre2_match()</b>, is used. PCRE2 also has an alternative
+matching function, <b>pcre2_dfa_match()</b>, which matches using a different
+algorithm that is not Perl-compatible. Some of the features discussed below are
+not available when DFA matching is used. The advantages and disadvantages of
+the alternative function, and how it differs from the normal function, are
+discussed in the
+<a href="pcre2matching.html"><b>pcre2matching</b></a>
+page.
+</P>
+<br><a name="SEC2" href="#TOC1">SPECIAL START-OF-PATTERN ITEMS</a><br>
+<P>
+A number of options that can be passed to <b>pcre2_compile()</b> can also be set
+by special items at the start of a pattern. These are not Perl-compatible, but
+are provided to make these options accessible to pattern writers who are not
+able to change the program that processes the pattern. Any number of these
+items may appear, but they must all be together right at the start of the
+pattern string, and the letters must be in upper case.
+</P>
+<br><b>
+UTF support
+</b><br>
+<P>
+In the 8-bit and 16-bit PCRE2 libraries, characters may be coded either as
+single code units, or as multiple UTF-8 or UTF-16 code units. UTF-32 can be
+specified for the 32-bit library, in which case it constrains the character
+values to valid Unicode code points. To process UTF strings, PCRE2 must be
+built to include Unicode support (which is the default). When using UTF strings
+you must either call the compiling function with the PCRE2_UTF option, or the
+pattern must start with the special sequence (*UTF), which is equivalent to
+setting the relevant option. How setting a UTF mode affects pattern matching is
+mentioned in several places below. There is also a summary of features in the
+<a href="pcre2unicode.html"><b>pcre2unicode</b></a>
+page.
+</P>
+<P>
+Some applications that allow their users to supply patterns may wish to
+restrict them to non-UTF data for security reasons. If the PCRE2_NEVER_UTF
+option is passed to <b>pcre2_compile()</b>, (*UTF) is not allowed, and its
+appearance in a pattern causes an error.
+</P>
+<br><b>
+Unicode property support
+</b><br>
+<P>
+Another special sequence that may appear at the start of a pattern is (*UCP).
+This has the same effect as setting the PCRE2_UCP option: it causes sequences
+such as \d and \w to use Unicode properties to determine character types,
+instead of recognizing only characters with codes less than 256 via a lookup
+table.
+</P>
+<P>
+Some applications that allow their users to supply patterns may wish to
+restrict them for security reasons. If the PCRE2_NEVER_UCP option is passed to
+<b>pcre2_compile()</b>, (*UCP) is not allowed, and its appearance in a pattern
+causes an error.
+</P>
+<br><b>
+Locking out empty string matching
+</b><br>
+<P>
+Starting a pattern with (*NOTEMPTY) or (*NOTEMPTY_ATSTART) has the same effect
+as passing the PCRE2_NOTEMPTY or PCRE2_NOTEMPTY_ATSTART option to whichever
+matching function is subsequently called to match the pattern. These options
+lock out the matching of empty strings, either entirely, or only at the start
+of the subject.
+</P>
+<br><b>
+Disabling auto-possessification
+</b><br>
+<P>
+If a pattern starts with (*NO_AUTO_POSSESS), it has the same effect as setting
+the PCRE2_NO_AUTO_POSSESS option. This stops PCRE2 from making quantifiers
+possessive when what follows cannot match the repeated item. For example, by
+default a+b is treated as a++b. For more details, see the
+<a href="pcre2api.html"><b>pcre2api</b></a>
+documentation.
+</P>
+<br><b>
+Disabling start-up optimizations
+</b><br>
+<P>
+If a pattern starts with (*NO_START_OPT), it has the same effect as setting the
+PCRE2_NO_START_OPTIMIZE option. This disables several optimizations for quickly
+reaching "no match" results. For more details, see the
+<a href="pcre2api.html"><b>pcre2api</b></a>
+documentation.
+</P>
+<br><b>
+Disabling automatic anchoring
+</b><br>
+<P>
+If a pattern starts with (*NO_DOTSTAR_ANCHOR), it has the same effect as
+setting the PCRE2_NO_DOTSTAR_ANCHOR option. This disables optimizations that
+apply to patterns whose top-level branches all start with .* (match any number
+of arbitrary characters). For more details, see the
+<a href="pcre2api.html"><b>pcre2api</b></a>
+documentation.
+</P>
+<br><b>
+Disabling JIT compilation
+</b><br>
+<P>
+If a pattern that starts with (*NO_JIT) is successfully compiled, an attempt by
+the application to apply the JIT optimization by calling
+<b>pcre2_jit_compile()</b> is ignored.
+</P>
+<br><b>
+Setting match and recursion limits
+</b><br>
+<P>
+The caller of <b>pcre2_match()</b> can set a limit on the number of times the
+internal <b>match()</b> function is called and on the maximum depth of
+recursive calls. These facilities are provided to catch runaway matches that
+are provoked by patterns with huge matching trees (a typical example is a
+pattern with nested unlimited repeats) and to avoid running out of system stack
+by too much recursion. When one of these limits is reached, <b>pcre2_match()</b>
+gives an error return. The limits can also be set by items at the start of the
+pattern of the form
+<pre>
+ (*LIMIT_MATCH=d)
+ (*LIMIT_RECURSION=d)
+</pre>
+where d is any number of decimal digits. However, the value of the setting must
+be less than the value set (or defaulted) by the caller of <b>pcre2_match()</b>
+for it to have any effect. In other words, the pattern writer can lower the
+limits set by the programmer, but not raise them. If there is more than one
+setting of one of these limits, the lower value is used.
+<a name="newlines"></a></P>
+<br><b>
+Newline conventions
+</b><br>
+<P>
+PCRE2 supports five different conventions for indicating line breaks in
+strings: a single CR (carriage return) character, a single LF (linefeed)
+character, the two-character sequence CRLF, any of the three preceding, or any
+Unicode newline sequence. The
+<a href="pcre2api.html"><b>pcre2api</b></a>
+page has
+<a href="pcre2api.html#newlines">further discussion</a>
+about newlines, and shows how to set the newline convention when calling
+<b>pcre2_compile()</b>.
+</P>
+<P>
+It is also possible to specify a newline convention by starting a pattern
+string with one of the following five sequences:
+<pre>
+ (*CR) carriage return
+ (*LF) linefeed
+ (*CRLF) carriage return, followed by linefeed
+ (*ANYCRLF) any of the three above
+ (*ANY) all Unicode newline sequences
+</pre>
+These override the default and the options given to the compiling function. For
+example, on a Unix system where LF is the default newline sequence, the pattern
+<pre>
+ (*CR)a.b
+</pre>
+changes the convention to CR. That pattern matches "a\nb" because LF is no
+longer a newline. If more than one of these settings is present, the last one
+is used.
+</P>
+<P>
+The newline convention affects where the circumflex and dollar assertions are
+true. It also affects the interpretation of the dot metacharacter when
+PCRE2_DOTALL is not set, and the behaviour of \N. However, it does not affect
+what the \R escape sequence matches. By default, this is any Unicode newline
+sequence, for Perl compatibility. However, this can be changed; see the
+description of \R in the section entitled
+<a href="#newlineseq">"Newline sequences"</a>
+below. A change of \R setting can be combined with a change of newline
+convention.
+</P>
+<br><b>
+Specifying what \R matches
+</b><br>
+<P>
+It is possible to restrict \R to match only CR, LF, or CRLF (instead of the
+complete set of Unicode line endings) by setting the option PCRE2_BSR_ANYCRLF
+at compile time. This effect can also be achieved by starting a pattern with
+(*BSR_ANYCRLF). For completeness, (*BSR_UNICODE) is also recognized,
+corresponding to PCRE2_BSR_UNICODE.
+</P>
+<br><a name="SEC3" href="#TOC1">EBCDIC CHARACTER CODES</a><br>
+<P>
+PCRE2 can be compiled to run in an environment that uses EBCDIC as its
+character code rather than ASCII or Unicode (typically a mainframe system). In
+the sections below, character code values are ASCII or Unicode; in an EBCDIC
+environment these characters may have different code values, and there are no
+code points greater than 255.
+</P>
+<br><a name="SEC4" href="#TOC1">CHARACTERS AND METACHARACTERS</a><br>
+<P>
+A regular expression is a pattern that is matched against a subject string from
+left to right. Most characters stand for themselves in a pattern, and match the
+corresponding characters in the subject. As a trivial example, the pattern
+<pre>
+ The quick brown fox
+</pre>
+matches a portion of a subject string that is identical to itself. When
+caseless matching is specified (the PCRE2_CASELESS option), letters are matched
+independently of case.
+</P>
+<P>
+The power of regular expressions comes from the ability to include alternatives
+and repetitions in the pattern. These are encoded in the pattern by the use of
+<i>metacharacters</i>, which do not stand for themselves but instead are
+interpreted in some special way.
+</P>
+<P>
+There are two different sets of metacharacters: those that are recognized
+anywhere in the pattern except within square brackets, and those that are
+recognized within square brackets. Outside square brackets, the metacharacters
+are as follows:
+<pre>
+ \ general escape character with several uses
+ ^ assert start of string (or line, in multiline mode)
+ $ assert end of string (or line, in multiline mode)
+ . match any character except newline (by default)
+ [ start character class definition
+ | start of alternative branch
+ ( start subpattern
+ ) end subpattern
+ ? extends the meaning of (
+ also 0 or 1 quantifier
+ also quantifier minimizer
+ * 0 or more quantifier
+ + 1 or more quantifier
+ also "possessive quantifier"
+ { start min/max quantifier
+</pre>
+Part of a pattern that is in square brackets is called a "character class". In
+a character class the only metacharacters are:
+<pre>
+ \ general escape character
+ ^ negate the class, but only if the first character
+ - indicates character range
+ [ POSIX character class (only if followed by POSIX syntax)
+ ] terminates the character class
+</pre>
+The following sections describe the use of each of the metacharacters.
+</P>
+<br><a name="SEC5" href="#TOC1">BACKSLASH</a><br>
+<P>
+The backslash character has several uses. Firstly, if it is followed by a
+character that is not a number or a letter, it takes away any special meaning
+that character may have. This use of backslash as an escape character applies
+both inside and outside character classes.
+</P>
+<P>
+For example, if you want to match a * character, you write \* in the pattern.
+This escaping action applies whether or not the following character would
+otherwise be interpreted as a metacharacter, so it is always safe to precede a
+non-alphanumeric with backslash to specify that it stands for itself. In
+particular, if you want to match a backslash, you write \\.
+</P>
+<P>
+In a UTF mode, only ASCII numbers and letters have any special meaning after a
+backslash. All other characters (in particular, those whose codepoints are
+greater than 127) are treated as literals.
+</P>
+<P>
+If a pattern is compiled with the PCRE2_EXTENDED option, most white space in
+the pattern (other than in a character class), and characters between a #
+outside a character class and the next newline, inclusive, are ignored. An
+escaping backslash can be used to include a white space or # character as part
+of the pattern.
+</P>
+<P>
+If you want to remove the special meaning from a sequence of characters, you
+can do so by putting them between \Q and \E. This is different from Perl in
+that $ and @ are handled as literals in \Q...\E sequences in PCRE2, whereas
+in Perl, $ and @ cause variable interpolation. Note the following examples:
+<pre>
+ Pattern PCRE2 matches Perl matches
+
+ \Qabc$xyz\E abc$xyz abc followed by the contents of $xyz
+ \Qabc\$xyz\E abc\$xyz abc\$xyz
+ \Qabc\E\$\Qxyz\E abc$xyz abc$xyz
+</pre>
+The \Q...\E sequence is recognized both inside and outside character classes.
+An isolated \E that is not preceded by \Q is ignored. If \Q is not followed
+by \E later in the pattern, the literal interpretation continues to the end of
+the pattern (that is, \E is assumed at the end). If the isolated \Q is inside
+a character class, this causes an error, because the character class is not
+terminated.
+<a name="digitsafterbackslash"></a></P>
+<br><b>
+Non-printing characters
+</b><br>
+<P>
+A second use of backslash provides a way of encoding non-printing characters
+in patterns in a visible manner. There is no restriction on the appearance of
+non-printing characters in a pattern, but when a pattern is being prepared by
+text editing, it is often easier to use one of the following escape sequences
+than the binary character it represents. In an ASCII or Unicode environment,
+these escapes are as follows:
+<pre>
+ \a alarm, that is, the BEL character (hex 07)
+ \cx "control-x", where x is any printable ASCII character
+ \e escape (hex 1B)
+ \f form feed (hex 0C)
+ \n linefeed (hex 0A)
+ \r carriage return (hex 0D)
+ \t tab (hex 09)
+ \0dd character with octal code 0dd
+ \ddd character with octal code ddd, or back reference
+ \o{ddd..} character with octal code ddd..
+ \xhh character with hex code hh
+ \x{hhh..} character with hex code hhh.. (default mode)
+ \uhhhh character with hex code hhhh (when PCRE2_ALT_BSUX is set)
+</pre>
+The precise effect of \cx on ASCII characters is as follows: if x is a lower
+case letter, it is converted to upper case. Then bit 6 of the character (hex
+40) is inverted. Thus \cA to \cZ become hex 01 to hex 1A (A is 41, Z is 5A),
+but \c{ becomes hex 3B ({ is 7B), and \c; becomes hex 7B (; is 3B). If the
+code unit following \c has a value less than 32 or greater than 126, a
+compile-time error occurs. This locks out non-printable ASCII characters in all
+modes.
+</P>
+<P>
+When PCRE2 is compiled in EBCDIC mode, \a, \e, \f, \n, \r, and \t
+generate the appropriate EBCDIC code values. The \c escape is processed
+as specified for Perl in the <b>perlebcdic</b> document. The only characters
+that are allowed after \c are A-Z, a-z, or one of @, [, \, ], ^, _, or ?. Any
+other character provokes a compile-time error. The sequence \@ encodes
+character code 0; the letters (in either case) encode characters 1-26 (hex 01
+to hex 1A); [, \, ], ^, and _ encode characters 27-31 (hex 1B to hex 1F), and
+\? becomes either 255 (hex FF) or 95 (hex 5F).
+</P>
+<P>
+Thus, apart from \?, these escapes generate the same character code values as
+they do in an ASCII environment, though the meanings of the values mostly
+differ. For example, \G always generates code value 7, which is BEL in ASCII
+but DEL in EBCDIC.
+</P>
+<P>
+The sequence \? generates DEL (127, hex 7F) in an ASCII environment, but
+because 127 is not a control character in EBCDIC, Perl makes it generate the
+APC character. Unfortunately, there are several variants of EBCDIC. In most of
+them the APC character has the value 255 (hex FF), but in the one Perl calls
+POSIX-BC its value is 95 (hex 5F). If certain other characters have POSIX-BC
+values, PCRE2 makes \? generate 95; otherwise it generates 255.
+</P>
+<P>
+After \0 up to two further octal digits are read. If there are fewer than two
+digits, just those that are present are used. Thus the sequence \0\x\015
+specifies two binary zeros followed by a CR character (code value 13). Make
+sure you supply two digits after the initial zero if the pattern character that
+follows is itself an octal digit.
+</P>
+<P>
+The escape \o must be followed by a sequence of octal digits, enclosed in
+braces. An error occurs if this is not the case. This escape is a recent
+addition to Perl; it provides way of specifying character code points as octal
+numbers greater than 0777, and it also allows octal numbers and back references
+to be unambiguously specified.
+</P>
+<P>
+For greater clarity and unambiguity, it is best to avoid following \ by a
+digit greater than zero. Instead, use \o{} or \x{} to specify character
+numbers, and \g{} to specify back references. The following paragraphs
+describe the old, ambiguous syntax.
+</P>
+<P>
+The handling of a backslash followed by a digit other than 0 is complicated,
+and Perl has changed over time, causing PCRE2 also to change.
+</P>
+<P>
+Outside a character class, PCRE2 reads the digit and any following digits as a
+decimal number. If the number is less than 10, begins with the digit 8 or 9, or
+if there are at least that many previous capturing left parentheses in the
+expression, the entire sequence is taken as a <i>back reference</i>. A
+description of how this works is given
+<a href="#backreferences">later,</a>
+following the discussion of
+<a href="#subpattern">parenthesized subpatterns.</a>
+Otherwise, up to three octal digits are read to form a character code.
+</P>
+<P>
+Inside a character class, PCRE2 handles \8 and \9 as the literal characters
+"8" and "9", and otherwise reads up to three octal digits following the
+backslash, using them to generate a data character. Any subsequent digits stand
+for themselves. For example, outside a character class:
+<pre>
+ \040 is another way of writing an ASCII space
+ \40 is the same, provided there are fewer than 40 previous capturing subpatterns
+ \7 is always a back reference
+ \11 might be a back reference, or another way of writing a tab
+ \011 is always a tab
+ \0113 is a tab followed by the character "3"
+ \113 might be a back reference, otherwise the character with octal code 113
+ \377 might be a back reference, otherwise the value 255 (decimal)
+ \81 is always a back reference .sp
+</pre>
+Note that octal values of 100 or greater that are specified using this syntax
+must not be introduced by a leading zero, because no more than three octal
+digits are ever read.
+</P>
+<P>
+By default, after \x that is not followed by {, from zero to two hexadecimal
+digits are read (letters can be in upper or lower case). Any number of
+hexadecimal digits may appear between \x{ and }. If a character other than

+Characters whose value is less than 256 can be defined by either of the two

+</P>
+<br><b>
+Escape sequences in character classes
+</b><br>
+<P>
+All the sequences that define a single character value can be used both inside
+and outside character classes. In addition, inside a character class, \b is
+interpreted as the backspace character (hex 08).
+</P>
+<P>
+\N is not allowed in a character class. \B, \R, and \X are not special
+inside a character class. Like other unrecognized alphabetic escape sequences,
+they cause an error. Outside a character class, these sequences have different
+meanings.
+</P>
+<br><b>
+Unsupported escape sequences
+</b><br>
+<P>
+In Perl, the sequences \l, \L, \u, and \U are recognized by its string
+handler and used to modify the case of following characters. By default, PCRE2
+does not support these escape sequences. However, if the PCRE2_ALT_BSUX option
+is set, \U matches a "U" character, and \u can be used to define a character
+by code point, as described in the previous section.
+</P>
+<br><b>
+Absolute and relative back references
+</b><br>
+<P>
+The sequence \g followed by an unsigned or a negative number, optionally

+<a name="genericchartypes"></a></P>
+<br><b>
+Generic character types
+</b><br>
+<P>
+Another use of backslash is for specifying generic character types:
+<pre>
+ \d any decimal digit
+ \D any character that is not a decimal digit
+ \h any horizontal white space character
+ \H any character that is not a horizontal white space character
+ \s any white space character
+ \S any character that is not a white space character
+ \v any vertical white space character
+ \V any character that is not a vertical white space character
+ \w any "word" character
+ \W any "non-word" character
+</pre>
+There is also the single sequence \N, which matches a non-newline character.
+This is the same as
+<a href="#fullstopdot">the "." metacharacter</a>
+when PCRE2_DOTALL is not set. Perl also uses \N to match characters by name;
+PCRE2 does not support this.
+</P>
+<P>
+Each pair of lower and upper case escape sequences partitions the complete set
+of characters into two disjoint sets. Any given character matches one, and only
+one, of each pair. The sequences can appear both inside and outside character
+classes. They each match one character of the appropriate type. If the current
+matching point is at the end of the subject string, all of them fail, because
+there is no character to match.
+</P>
+<P>
+The default \s characters are HT (9), LF (10), VT (11), FF (12), CR (13), and
+space (32), which are defined as white space in the "C" locale. This list may
+vary if locale-specific matching is taking place. For example, in some locales
+the "non-breaking space" character (\xA0) is recognized as white space, and in
+others the VT character is not.
+</P>
+<P>
+A "word" character is an underscore or any character that is a letter or digit.
+By default, the definition of letters and digits is controlled by PCRE2's
+low-valued character tables, and may vary if locale-specific matching is taking
+place (see
+<a href="pcre2api.html#localesupport">"Locale support"</a>
+in the
+<a href="pcre2api.html"><b>pcre2api</b></a>
+page). For example, in a French locale such as "fr_FR" in Unix-like systems,
+or "french" in Windows, some character codes greater than 127 are used for
+accented letters, and these are then matched by \w. The use of locales with
+Unicode is discouraged.
+</P>
+<P>
+By default, characters whose code points are greater than 127 never match \d,
+\s, or \w, and always match \D, \S, and \W, although this may be different
+for characters in the range 128-255 when locale-specific matching is happening.
+These escape sequences retain their original meanings from before Unicode
+support was available, mainly for efficiency reasons. If the PCRE2_UCP option
+is set, the behaviour is changed so that Unicode properties are used to
+determine character types, as follows:
+<pre>
+ \d any character that matches \p{Nd} (decimal digit)
+ \s any character that matches \p{Z} or \h or \v
+ \w any character that matches \p{L} or \p{N}, plus underscore
+</pre>
+The upper case escapes match the inverse sets of characters. Note that \d
+matches only decimal digits, whereas \w matches any Unicode digit, as well as
+any Unicode letter, and underscore. Note also that PCRE2_UCP affects \b, and
+\B because they are defined in terms of \w and \W. Matching these sequences
+is noticeably slower when PCRE2_UCP is set.
+</P>
+<P>
+The sequences \h, \H, \v, and \V, in contrast to the other sequences, which
+match only ASCII characters by default, always match a specific list of code
+points, whether or not PCRE2_UCP is set. The horizontal space characters are:
+<pre>
+ U+0009 Horizontal tab (HT)
+ U+0020 Space
+ U+00A0 Non-break space
+ U+1680 Ogham space mark
+ U+180E Mongolian vowel separator

+ U+200A Hair space

+In 8-bit, non-UTF-8 mode, only the characters with code points less than 256
+are relevant.
+<a name="newlineseq"></a></P>
+<br><b>
+Newline sequences
+</b><br>
+<P>
+Outside a character class, by default, the escape sequence \R matches any
+Unicode newline sequence. In 8-bit non-UTF-8 mode \R is equivalent to the
+following:
+<pre>
+ (?>\r\n|\n|\x0b|\f|\r|\x85)
+</pre>
+This is an example of an "atomic group", details of which are given
+<a href="#atomicgroup">below.</a>
+This particular group matches either the two-character sequence CR followed by
+LF, or one of the single characters LF (linefeed, U+000A), VT (vertical tab,
+U+000B), FF (form feed, U+000C), CR (carriage return, U+000D), or NEL (next
+line, U+0085). Because this is an atomic group, the two-character sequence is
+treated as a single unit that cannot be split.
+</P>
+<P>
+In other modes, two additional characters whose codepoints are greater than 255
+are added: LS (line separator, U+2028) and PS (paragraph separator, U+2029).
+Unicode support is not needed for these characters to be recognized.
+</P>
+<P>
+It is possible to restrict \R to match only CR, LF, or CRLF (instead of the
+complete set of Unicode line endings) by setting the option PCRE2_BSR_ANYCRLF
+at compile time. (BSR is an abbrevation for "backslash R".) This can be made
+the default when PCRE2 is built; if this is the case, the other behaviour can
+be requested via the PCRE2_BSR_UNICODE option. It is also possible to specify
+these settings by starting a pattern string with one of the following
+sequences:
+<pre>
+ (*BSR_ANYCRLF) CR, LF, or CRLF only
+ (*BSR_UNICODE) any Unicode newline sequence
+</pre>
+These override the default and the options given to the compiling function.
+Note that these special settings, which are not Perl-compatible, are recognized
+only at the very start of a pattern, and that they must be in upper case. If
+more than one of them is present, the last one is used. They can be combined
+with a change of newline convention; for example, a pattern can start with:
+<pre>
+ (*ANY)(*BSR_ANYCRLF)
+</pre>
+They can also be combined with the (*UTF) or (*UCP) special sequences. Inside a
+character class, \R is treated as an unrecognized escape sequence, and causes
+an error.

+<br><b>
+Unicode character properties
+</b><br>
+<P>
+When PCRE2 is built with Unicode support (the default), three additional escape
+sequences that match characters with specific properties are available. In
+8-bit non-UTF-8 mode, these sequences are of course limited to testing
+characters whose codepoints are less than 256, but they do work in this mode.
+The extra escape sequences are:
+<pre>
+ \p{<i>xx</i>} a character with the <i>xx</i> property
+ \P{<i>xx</i>} a character without the <i>xx</i> property
+ \X a Unicode extended grapheme cluster
+</pre>
+The property names represented by <i>xx</i> above are limited to the Unicode
+script names, the general category properties, "Any", which matches any
+character (including newline), and some special PCRE2 properties (described
+in the
+<a href="#extraprops">next section).</a>
+Other Perl properties such as "InMusicalSymbols" are not supported by PCRE2.
+Note that \P{Any} does not match any characters, so always causes a match
+failure.
+</P>
+<P>
+Sets of Unicode characters are defined as belonging to certain scripts. A
+character from one of these sets can be matched using a script name. For
+example:
+<pre>

+Each character has exactly one Unicode general category property, specified by
+a two-letter abbreviation. For compatibility with Perl, negation can be

+name. For example, \p{^Lu} is the same as \P{Lu}.
+</P>
+<P>
+If only one letter is specified with \p or \P, it includes all the general
+category properties that start with that letter. In this case, in the absence
+of negation, the curly brackets in the escape sequence are optional; these two
+examples have the same effect:
+<pre>
+ \p{L}
+ \pL
+</pre>
+The following general category property codes are supported:
+<pre>
+ C Other

+The special property L& is also supported: it matches a character that has
+the Lu, Ll, or Lt property, in other words, a letter that is not classified as
+a modifier or "other".
+</P>
+<P>
+The Cs (Surrogate) property applies only to characters in the range U+D800 to
+U+DFFF. Such characters are not valid in Unicode strings and so
+cannot be tested by PCRE2, unless UTF validity checking has been turned off
+(see the discussion of PCRE2_NO_UTF_CHECK in the
+<a href="pcre2api.html"><b>pcre2api</b></a>
+page). Perl does not support the Cs property.
+</P>
+<P>
+The long synonyms for property names that Perl supports (such as \p{Letter})
+are not supported by PCRE2, nor is it permitted to prefix any of these
+properties with "Is".
+</P>
+<P>
+No character that is in the Unicode table has the Cn (unassigned) property.
+Instead, this property is assumed for any code point that is not in the
+Unicode table.
+</P>
+<P>
+Specifying caseless matching does not affect these escape sequences. For
+example, \p{Lu} always matches only upper case letters. This is different from
+the behaviour of current versions of Perl.
+</P>
+<P>
+Matching characters by Unicode property is not fast, because PCRE2 has to do a
+multistage table lookup in order to find a character's property. That is why
+the traditional escape sequences such as \d and \w do not use Unicode
+properties in PCRE2 by default, though you can make them do so by setting the
+PCRE2_UCP option or by starting the pattern with (*UCP).
+</P>
+<br><b>
+Extended grapheme clusters
+</b><br>
+<P>
+The \X escape matches any number of Unicode characters that form an "extended
+grapheme cluster", and treats the sequence as an atomic group
+<a href="#atomicgroup">(see below).</a>
+Unicode supports various kinds of composite character by giving each character
+a grapheme breaking property, and having rules that use these properties to
+define the boundaries of extended grapheme clusters. \X always matches at
+least one character. Then it decides whether to add additional characters
+according to the following rules for ending a cluster:
+</P>
+<P>
+1. End at the end of the subject string.
+</P>
+<P>
+2. Do not end between CR and LF; otherwise end after any control character.
+</P>
+<P>
+3. Do not break Hangul (a Korean script) syllable sequences. Hangul characters
+are of five types: L, V, T, LV, and LVT. An L character may be followed by an
+L, V, LV, or LVT character; an LV or V character may be followed by a V or T
+character; an LVT or T character may be follwed only by a T character.
+</P>
+<P>
+4. Do not end before extending characters or spacing marks. Characters with
+the "mark" property always have the "extend" grapheme breaking property.
+</P>
+<P>
+5. Do not end after prepend characters.
+</P>
+<P>
+6. Otherwise, end the cluster.
+<a name="extraprops"></a></P>
+<br><b>
+PCRE2's additional properties
+</b><br>
+<P>
+As well as the standard Unicode properties described above, PCRE2 supports four
+more that make it possible to convert traditional escape sequences such as \w
+and \s to use Unicode properties. PCRE2 uses these non-standard, non-Perl
+properties internally when PCRE2_UCP is set. However, they may also be used
+explicitly. These properties are:
+<pre>
+ Xan Any alphanumeric character
+ Xps Any POSIX space character
+ Xsp Any Perl space character
+ Xwd Any Perl "word" character
+</pre>
+Xan matches characters that have either the L (letter) or the N (number)
+property. Xps matches the characters tab, linefeed, vertical tab, form feed, or
+carriage return, and any other character that has the Z (separator) property.
+Xsp is the same as Xps; in PCRE1 it used to exclude vertical tab, for Perl
+compatibility, but Perl changed. Xwd matches the same characters as Xan, plus
+underscore.
+</P>
+<P>
+There is another non-standard property, Xuc, which matches any character that
+can be represented by a Universal Character Name in C++ and other programming
+languages. These are the characters $, @, ` (grave accent), and all characters
+with Unicode code points greater than or equal to U+00A0, except for the
+surrogates U+D800 to U+DFFF. Note that most base (ASCII) characters are
+excluded. (Universal Character Names are of the form \uHHHH or \UHHHHHHHH
+where H is a hexadecimal digit. Note that the Xuc property does not match these
+sequences but the characters that they represent.)
+<a name="resetmatchstart"></a></P>
+<br><b>
+Resetting the match start
+</b><br>
+<P>
+The escape sequence \K causes any previously matched characters not to be
+included in the final matched sequence. For example, the pattern:
+<pre>
+ foo\Kbar
+</pre>
+matches "foobar", but reports that it has matched "bar". This feature is
+similar to a lookbehind assertion
+<a href="#lookbehind">(described below).</a>
+However, in this case, the part of the subject before the real match does not
+have to be of fixed length, as lookbehind assertions do. The use of \K does
+not interfere with the setting of
+<a href="#subpattern">captured substrings.</a>
+For example, when the pattern
+<pre>
+ (foo)\Kbar
+</pre>
+matches "foobar", the first substring is still set to "foo".
+</P>
+<P>
+Perl documents that the use of \K within assertions is "not well defined". In
+PCRE2, \K is acted upon when it occurs inside positive assertions, but is
+ignored in negative assertions. Note that when a pattern such as (?=ab\K)
+matches, the reported start of the match can be greater than the end of the
+match.
+<a name="smallassertions"></a></P>
+<br><b>
+Simple assertions
+</b><br>
+<P>
+The final use of backslash is for certain simple assertions. An assertion
+specifies a condition that has to be met at a particular point in a match,
+without consuming any characters from the subject string. The use of
+subpatterns for more complicated assertions is described
+<a href="#bigassertions">below.</a>
+The backslashed assertions are:
+<pre>
+ \b matches at a word boundary
+ \B matches when not at a word boundary
+ \A matches at the start of the subject
+ \Z matches at the end of the subject
+ also matches before a newline at the end of the subject
+ \z matches only at the end of the subject
+ \G matches at the first matching position in the subject
+</pre>
+Inside a character class, \b has a different meaning; it matches the backspace
+character. If any other of these assertions appears in a character class, an
+"invalid escape sequence" error is generated.
+</P>
+<P>
+A word boundary is a position in the subject string where the current character
+and the previous character do not both match \w or \W (i.e. one matches
+\w and the other matches \W), or the start or end of the string if the
+first or last character matches \w, respectively. In a UTF mode, the meanings
+of \w and \W can be changed by setting the PCRE2_UCP option. When this is
+done, it also affects \b and \B. Neither PCRE2 nor Perl has a separate "start
+of word" or "end of word" metasequence. However, whatever follows \b normally
+determines which it is. For example, the fragment \ba matches "a" at the start
+of a word.
+</P>
+<P>
+The \A, \Z, and \z assertions differ from the traditional circumflex and
+dollar (described in the next section) in that they only ever match at the very
+start and end of the subject string, whatever options are set. Thus, they are
+independent of multiline mode. These three assertions are not affected by the
+PCRE2_NOTBOL or PCRE2_NOTEOL options, which affect only the behaviour of the
+circumflex and dollar metacharacters. However, if the <i>startoffset</i>
+argument of <b>pcre2_match()</b> is non-zero, indicating that matching is to
+start at a point other than the beginning of the subject, \A can never match.
+The difference between \Z and \z is that \Z matches before a newline at the
+end of the string as well as at the very end, whereas \z matches only at the
+end.
+</P>
+<P>
+The \G assertion is true only when the current matching position is at the
+start point of the match, as specified by the <i>startoffset</i> argument of
+<b>pcre2_match()</b>. It differs from \A when the value of <i>startoffset</i> is
+non-zero. By calling <b>pcre2_match()</b> multiple times with appropriate
+arguments, you can mimic Perl's /g option, and it is in this kind of
+implementation where \G can be useful.
+</P>
+<P>
+Note, however, that PCRE2's interpretation of \G, as the start of the current
+match, is subtly different from Perl's, which defines it as the end of the
+previous match. In Perl, these can be different when the previously matched
+string was empty. Because PCRE2 does just one match at a time, it cannot
+reproduce this behaviour.
+</P>
+<P>
+If all the alternatives of a pattern begin with \G, the expression is anchored
+to the starting match position, and the "anchored" flag is set in the compiled
+regular expression.
+</P>
+<br><a name="SEC6" href="#TOC1">CIRCUMFLEX AND DOLLAR</a><br>
+<P>
+The circumflex and dollar metacharacters are zero-width assertions. That is,
+they test for a particular condition being true without consuming any
+characters from the subject string. These two metacharacters are concerned with
+matching the starts and ends of lines. If the newline convention is set so that
+only the two-character sequence CRLF is recognized as a newline, isolated CR
+and LF characters are treated as ordinary data characters, and are not
+recognized as newlines.
+</P>
+<P>
+Outside a character class, in the default matching mode, the circumflex
+character is an assertion that is true only if the current matching point is at
+the start of the subject string. If the <i>startoffset</i> argument of
+<b>pcre2_match()</b> is non-zero, or if PCRE2_NOTBOL is set, circumflex can
+never match if the PCRE2_MULTILINE option is unset. Inside a character class,
+circumflex has an entirely different meaning
+<a href="#characterclass">(see below).</a>
+</P>
+<P>
+Circumflex need not be the first character of the pattern if a number of
+alternatives are involved, but it should be the first thing in each alternative
+in which it appears if the pattern is ever to match that branch. If all
+possible alternatives start with a circumflex, that is, if the pattern is
+constrained to match only at the start of the subject, it is said to be an
+"anchored" pattern. (There are also other constructs that can cause a pattern
+to be anchored.)
+</P>
+<P>
+The dollar character is an assertion that is true only if the current matching
+point is at the end of the subject string, or immediately before a newline at
+the end of the string (by default), unless PCRE2_NOTEOL is set. Note, however,
+that it does not actually match the newline. Dollar need not be the last
+character of the pattern if a number of alternatives are involved, but it
+should be the last item in any branch in which it appears. Dollar has no
+special meaning in a character class.
+</P>
+<P>
+The meaning of dollar can be changed so that it matches only at the very end of
+the string, by setting the PCRE2_DOLLAR_ENDONLY option at compile time. This
+does not affect the \Z assertion.
+</P>
+<P>
+The meanings of the circumflex and dollar metacharacters are changed if the
+PCRE2_MULTILINE option is set. When this is the case, a dollar character
+matches before any newlines in the string, as well as at the very end, and a
+circumflex matches immediately after internal newlines as well as at the start
+of the subject string. It does not match after a newline that ends the string,
+for compatibility with Perl. However, this can be changed by setting the
+PCRE2_ALT_CIRCUMFLEX option.
+</P>
+<P>
+For example, the pattern /^abc$/ matches the subject string "def\nabc" (where
+\n represents a newline) in multiline mode, but not otherwise. Consequently,
+patterns that are anchored in single line mode because all branches start with
+^ are not anchored in multiline mode, and a match for circumflex is possible
+when the <i>startoffset</i> argument of <b>pcre2_match()</b> is non-zero. The
+PCRE2_DOLLAR_ENDONLY option is ignored if PCRE2_MULTILINE is set.
+</P>
+<P>
+When the newline convention (see
+<a href="#newlines">"Newline conventions"</a>
+below) recognizes the two-character sequence CRLF as a newline, this is
+preferred, even if the single characters CR and LF are also recognized as
+newlines. For example, if the newline convention is "any", a multiline mode
+circumflex matches before "xyz" in the string "abc\r\nxyz" rather than after
+CR, even though CR on its own is a valid newline. (It also matches at the very
+start of the string, of course.)
+</P>
+<P>
+Note that the sequences \A, \Z, and \z can be used to match the start and
+end of the subject in both modes, and if all branches of a pattern start with
+\A it is always anchored, whether or not PCRE2_MULTILINE is set.
+<a name="fullstopdot"></a></P>
+<br><a name="SEC7" href="#TOC1">FULL STOP (PERIOD, DOT) AND \N</a><br>
+<P>
+Outside a character class, a dot in the pattern matches any one character in
+the subject string except (by default) a character that signifies the end of a
+line.
+</P>
+<P>
+When a line ending is defined as a single character, dot never matches that
+character; when the two-character sequence CRLF is used, dot does not match CR
+if it is immediately followed by LF, but otherwise it matches all characters
+(including isolated CRs and LFs). When any Unicode line endings are being
+recognized, dot does not match CR or LF or any of the other line ending
+characters.
+</P>
+<P>
+The behaviour of dot with regard to newlines can be changed. If the
+PCRE2_DOTALL option is set, a dot matches any one character, without exception.
+If the two-character sequence CRLF is present in the subject string, it takes
+two dots to match it.
+</P>
+<P>
+The handling of dot is entirely independent of the handling of circumflex and
+dollar, the only relationship being that they both involve newlines. Dot has no
+special meaning in a character class.
+</P>
+<P>
+The escape sequence \N behaves like a dot, except that it is not affected by
+the PCRE2_DOTALL option. In other words, it matches any character except one
+that signifies the end of a line. Perl also uses \N to match characters by
+name; PCRE2 does not support this.
+</P>
+<br><a name="SEC8" href="#TOC1">MATCHING A SINGLE CODE UNIT</a><br>
+<P>
+Outside a character class, the escape sequence \C matches any one code unit,
+whether or not a UTF mode is set. In the 8-bit library, one code unit is one
+byte; in the 16-bit library it is a 16-bit unit; in the 32-bit library it is a
+32-bit unit. Unlike a dot, \C always matches line-ending characters. The
+feature is provided in Perl in order to match individual bytes in UTF-8 mode,
+but it is unclear how it can usefully be used.
+</P>
+<P>
+Because \C breaks up characters into individual code units, matching one unit
+with \C in UTF-8 or UTF-16 mode means that the rest of the string may start
+with a malformed UTF character. This has undefined results, because PCRE2
+assumes that it is matching character by character in a valid UTF string (by
+default it checks the subject string's validity at the start of processing
+unless the PCRE2_NO_UTF_CHECK option is used).
+</P>
+<P>
+An application can lock out the use of \C by setting the
+PCRE2_NEVER_BACKSLASH_C option when compiling a pattern. It is also possible to
+build PCRE2 with the use of \C permanently disabled.
+</P>
+<P>
+PCRE2 does not allow \C to appear in lookbehind assertions
+<a href="#lookbehind">(described below)</a>
+in a UTF mode, because this would make it impossible to calculate the length of
+the lookbehind. Neither the alternative matching function
+<b>pcre2_dfa_match()</b> not the JIT optimizer support \C in a UTF mode. The
+former gives a match-time error; the latter fails to optimize and so the match
+is always run using the interpreter.
+</P>
+<P>
+In general, the \C escape sequence is best avoided. However, one way of using
+it that avoids the problem of malformed UTF characters is to use a lookahead to
+check the length of the next character, as in this pattern, which could be used
+with a UTF-8 string (ignore white space and line breaks):
+<pre>
+ (?| (?=[\x00-\x7f])(\C) |
+ (?=[\x80-\x{7ff}])(\C)(\C) |
+ (?=[\x{800}-\x{ffff}])(\C)(\C)(\C) |
+ (?=[\x{10000}-\x{1fffff}])(\C)(\C)(\C)(\C))
+</pre>
+In this example, a group that starts with (?| resets the capturing parentheses
+numbers in each alternative (see
+<a href="#dupsubpatternnumber">"Duplicate Subpattern Numbers"</a>
+below). The assertions at the start of each branch check the next UTF-8
+character for values whose encoding uses 1, 2, 3, or 4 bytes, respectively. The
+character's individual bytes are then captured by the appropriate number of
+\C groups.
+<a name="characterclass"></a></P>
+<br><a name="SEC9" href="#TOC1">SQUARE BRACKETS AND CHARACTER CLASSES</a><br>
+<P>
+An opening square bracket introduces a character class, terminated by a closing
+square bracket. A closing square bracket on its own is not special by default.
+If a closing square bracket is required as a member of the class, it should be
+the first data character in the class (after an initial circumflex, if present)
+or escaped with a backslash. This means that, by default, an empty class cannot
+be defined. However, if the PCRE2_ALLOW_EMPTY_CLASS option is set, a closing
+square bracket at the start does end the (empty) class.
+</P>
+<P>
+A character class matches a single character in the subject. A matched
+character must be in the set of characters defined by the class, unless the
+first character in the class definition is a circumflex, in which case the
+subject character must not be in the set defined by the class. If a circumflex
+is actually required as a member of the class, ensure it is not the first
+character, or escape it with a backslash.
+</P>
+<P>
+For example, the character class [aeiou] matches any lower case vowel, while
+[^aeiou] matches any character that is not a lower case vowel. Note that a
+circumflex is just a convenient notation for specifying the characters that
+are in the class by enumerating those that are not. A class that starts with a
+circumflex is not an assertion; it still consumes a character from the subject
+string, and therefore it fails if the current pointer is at the end of the
+string.
+</P>
+<P>
+When caseless matching is set, any letters in a class represent both their
+upper case and lower case versions, so for example, a caseless [aeiou] matches
+"A" as well as "a", and a caseless [^aeiou] does not match "A", whereas a
+caseful version would.
+</P>
+<P>
+Characters that might indicate line breaks are never treated in any special way
+when matching character classes, whatever line-ending sequence is in use, and
+whatever setting of the PCRE2_DOTALL and PCRE2_MULTILINE options is used. A
+class such as [^a] always matches one of these characters.
+</P>
+<P>
+The minus (hyphen) character can be used to specify a range of characters in a
+character class. For example, [d-m] matches any letter between d and m,
+inclusive. If a minus character is required in a class, it must be escaped with
+a backslash or appear in a position where it cannot be interpreted as
+indicating a range, typically as the first or last character in the class, or
+immediately after a range. For example, [b-d-z] matches letters in the range b
+to d, a hyphen character, or z.
+</P>
+<P>
+It is not possible to have the literal character "]" as the end character of a
+range. A pattern such as [W-]46] is interpreted as a class of two characters
+("W" and "-") followed by a literal string "46]", so it would match "W46]" or
+"-46]". However, if the "]" is escaped with a backslash it is interpreted as
+the end of range, so [W-\]46] is interpreted as a class containing a range
+followed by two other characters. The octal or hexadecimal representation of
+"]" can also be used to end a range.
+</P>
+<P>
+An error is generated if a POSIX character class (see below) or an escape
+sequence other than one that defines a single character appears at a point
+where a range ending character is expected. For example, [z-\xff] is valid,
+but [A-\d] and [A-[:digit:]] are not.
+</P>
+<P>
+Ranges normally include all code points between the start and end characters,
+inclusive. They can also be used for code points specified numerically, for
+example [\000-\037]. Ranges can include any characters that are valid for the
+current mode.
+</P>
+<P>
+There is a special case in EBCDIC environments for ranges whose end points are
+both specified as literal letters in the same case. For compatibility with
+Perl, EBCDIC code points within the range that are not letters are omitted. For
+example, [h-k] matches only four characters, even though the codes for h and k
+are 0x88 and 0x92, a range of 11 code points. However, if the range is
+specified numerically, for example, [\x88-\x92] or [h-\x92], all code points
+are included.
+</P>
+<P>
+If a range that includes letters is used when caseless matching is set, it
+matches the letters in either case. For example, [W-c] is equivalent to
+[][\\^_`wxyzabc], matched caselessly, and in a non-UTF mode, if character
+tables for a French locale are in use, [\xc8-\xcb] matches accented E
+characters in both cases.
+</P>
+<P>
+The character escape sequences \d, \D, \h, \H, \p, \P, \s, \S, \v,
+\V, \w, and \W may appear in a character class, and add the characters that
+they match to the class. For example, [\dABCDEF] matches any hexadecimal
+digit. In UTF modes, the PCRE2_UCP option affects the meanings of \d, \s, \w
+and their upper case partners, just as it does when they appear outside a
+character class, as described in the section entitled
+<a href="#genericchartypes">"Generic character types"</a>
+above. The escape sequence \b has a different meaning inside a character
+class; it matches the backspace character. The sequences \B, \N, \R, and \X
+are not special inside a character class. Like any other unrecognized escape
+sequences, they cause an error.
+</P>
+<P>
+A circumflex can conveniently be used with the upper case character types to
+specify a more restricted set of characters than the matching lower case type.
+For example, the class [^\W_] matches any letter or digit, but not underscore,
+whereas [\w] includes underscore. A positive character class should be read as
+"something OR something OR ..." and a negative class as "NOT something AND NOT
+something AND NOT ...".
+</P>
+<P>
+The only metacharacters that are recognized in character classes are backslash,
+hyphen (only where it can be interpreted as specifying a range), circumflex
+(only at the start), opening square bracket (only when it can be interpreted as
+introducing a POSIX class name, or for a special compatibility feature - see
+the next two sections), and the terminating closing square bracket. However,
+escaping other non-alphanumeric characters does no harm.
+</P>
+<br><a name="SEC10" href="#TOC1">POSIX CHARACTER CLASSES</a><br>
+<P>
+Perl supports the POSIX notation for character classes. This uses names
+enclosed by [: and :] within the enclosing square brackets. PCRE2 also supports
+this notation. For example,
+<pre>
+ [01[:alpha:]%]
+</pre>
+matches "0", "1", any alphabetic character, or "%". The supported class names
+are:
+<pre>
+ alnum letters and digits
+ alpha letters
+ ascii character codes 0 - 127
+ blank space or tab only
+ cntrl control characters
+ digit decimal digits (same as \d)
+ graph printing characters, excluding space
+ lower lower case letters
+ print printing characters, including space
+ punct printing characters, excluding letters and digits and space
+ space white space (the same as \s from PCRE2 8.34)
+ upper upper case letters
+ word "word" characters (same as \w)
+ xdigit hexadecimal digits
+</pre>
+The default "space" characters are HT (9), LF (10), VT (11), FF (12), CR (13),
+and space (32). If locale-specific matching is taking place, the list of space
+characters may be different; there may be fewer or more of them. "Space" and
+\s match the same set of characters.
+</P>
+<P>
+The name "word" is a Perl extension, and "blank" is a GNU extension from Perl
+5.8. Another Perl extension is negation, which is indicated by a ^ character
+after the colon. For example,
+<pre>
+ [12[:^digit:]]
+</pre>
+matches "1", "2", or any non-digit. PCRE2 (and Perl) also recognize the POSIX
+syntax [.ch.] and [=ch=] where "ch" is a "collating element", but these are not
+supported, and an error is given if they are encountered.
+</P>
+<P>
+By default, characters with values greater than 127 do not match any of the
+POSIX character classes, although this may be different for characters in the
+range 128-255 when locale-specific matching is happening. However, if the
+PCRE2_UCP option is passed to <b>pcre2_compile()</b>, some of the classes are
+changed so that Unicode character properties are used. This is achieved by
+replacing certain POSIX classes with other sequences, as follows:
+<pre>
+ [:alnum:] becomes \p{Xan}
+ [:alpha:] becomes \p{L}
+ [:blank:] becomes \h
+ [:cntrl:] becomes \p{Cc}
+ [:digit:] becomes \p{Nd}
+ [:lower:] becomes \p{Ll}
+ [:space:] becomes \p{Xps}
+ [:upper:] becomes \p{Lu}
+ [:word:] becomes \p{Xwd}
+</pre>
+Negated versions, such as [:^alpha:] use \P instead of \p. Three other POSIX
+classes are handled specially in UCP mode:
+</P>
+<P>
+[:graph:]
+This matches characters that have glyphs that mark the page when printed. In
+Unicode property terms, it matches all characters with the L, M, N, P, S, or Cf
+properties, except for:
+<pre>
+ U+061C Arabic Letter Mark
+ U+180E Mongolian Vowel Separator
+ U+2066 - U+2069 Various "isolate"s
+
+</PRE>
+</P>
+<P>
+[:print:]
+This matches the same characters as [:graph:] plus space characters that are
+not controls, that is, characters with the Zs property.
+</P>
+<P>
+[:punct:]
+This matches all characters that have the Unicode P (punctuation) property,
+plus those characters with code points less than 256 that have the S (Symbol)
+property.
+</P>
+<P>
+The other POSIX classes are unchanged, and match only characters with code
+points less than 256.
+</P>
+<br><a name="SEC11" href="#TOC1">COMPATIBILITY FEATURE FOR WORD BOUNDARIES</a><br>
+<P>
+In the POSIX.2 compliant library that was included in 4.4BSD Unix, the ugly
+syntax [[:<:]] and [[:>:]] is used for matching "start of word" and "end of
+word". PCRE2 treats these items as follows:
+<pre>
+ [[:<:]] is converted to \b(?=\w)
+ [[:>:]] is converted to \b(?<=\w)
+</pre>
+Only these exact character sequences are recognized. A sequence such as
+[a[:<:]b] provokes error for an unrecognized POSIX class name. This support is
+not compatible with Perl. It is provided to help migrations from other
+environments, and is best not used in any new patterns. Note that \b matches
+at the start and the end of a word (see
+<a href="#smallassertions">"Simple assertions"</a>
+above), and in a Perl-style pattern the preceding or following character
+normally shows which is wanted, without the need for the assertions that are
+used above in order to give exactly the POSIX behaviour.
+</P>
+<br><a name="SEC12" href="#TOC1">VERTICAL BAR</a><br>
+<P>
+Vertical bar characters are used to separate alternative patterns. For example,
+the pattern
+<pre>
+ gilbert|sullivan
+</pre>
+matches either "gilbert" or "sullivan". Any number of alternatives may appear,
+and an empty alternative is permitted (matching the empty string). The matching
+process tries each alternative in turn, from left to right, and the first one
+that succeeds is used. If the alternatives are within a subpattern
+<a href="#subpattern">(defined below),</a>
+"succeeds" means matching the rest of the main pattern as well as the
+alternative in the subpattern.
+</P>
+<br><a name="SEC13" href="#TOC1">INTERNAL OPTION SETTING</a><br>
+<P>
+The settings of the PCRE2_CASELESS, PCRE2_MULTILINE, PCRE2_DOTALL, and
+PCRE2_EXTENDED options (which are Perl-compatible) can be changed from within
+the pattern by a sequence of Perl option letters enclosed between "(?" and ")".
+The option letters are
+<pre>
+ i for PCRE2_CASELESS
+ m for PCRE2_MULTILINE
+ s for PCRE2_DOTALL
+ x for PCRE2_EXTENDED
+</pre>
+For example, (?im) sets caseless, multiline matching. It is also possible to
+unset these options by preceding the letter with a hyphen, and a combined
+setting and unsetting such as (?im-sx), which sets PCRE2_CASELESS and
+PCRE2_MULTILINE while unsetting PCRE2_DOTALL and PCRE2_EXTENDED, is also
+permitted. If a letter appears both before and after the hyphen, the option is
+unset. An empty options setting "(?)" is allowed. Needless to say, it has no
+effect.
+</P>
+<P>
+The PCRE2-specific options PCRE2_DUPNAMES and PCRE2_UNGREEDY can be changed in
+the same way as the Perl-compatible options by using the characters J and U
+respectively.
+</P>
+<P>
+When one of these option changes occurs at top level (that is, not inside
+subpattern parentheses), the change applies to the remainder of the pattern
+that follows. If the change is placed right at the start of a pattern, PCRE2
+extracts it into the global options (and it will therefore show up in data
+extracted by the <b>pcre2_pattern_info()</b> function).
+</P>
+<P>
+An option change within a subpattern (see below for a description of
+subpatterns) affects only that part of the subpattern that follows it, so
+<pre>
+ (a(?i)b)c
+</pre>
+matches abc and aBc and no other strings (assuming PCRE2_CASELESS is not used).
+By this means, options can be made to have different settings in different
+parts of the pattern. Any changes made in one alternative do carry on
+into subsequent branches within the same subpattern. For example,
+<pre>
+ (a(?i)b|c)
+</pre>
+matches "ab", "aB", "c", and "C", even though when matching "C" the first
+branch is abandoned before the option setting. This is because the effects of
+option settings happen at compile time. There would be some very weird
+behaviour otherwise.
+</P>
+<P>
+As a convenient shorthand, if any option settings are required at the start of
+a non-capturing subpattern (see the next section), the option letters may
+appear between the "?" and the ":". Thus the two patterns
+<pre>
+ (?i:saturday|sunday)
+ (?:(?i)saturday|sunday)
+</pre>
+match exactly the same set of strings.
+</P>
+<P>
+<b>Note:</b> There are other PCRE2-specific options that can be set by the
+application when the compiling function is called. The pattern can contain
+special leading sequences such as (*CRLF) to override what the application has
+set or what has been defaulted. Details are given in the section entitled
+<a href="#newlineseq">"Newline sequences"</a>
+above. There are also the (*UTF) and (*UCP) leading sequences that can be used
+to set UTF and Unicode property modes; they are equivalent to setting the
+PCRE2_UTF and PCRE2_UCP options, respectively. However, the application can set
+the PCRE2_NEVER_UTF and PCRE2_NEVER_UCP options, which lock out the use of the
+(*UTF) and (*UCP) sequences.
+<a name="subpattern"></a></P>
+<br><a name="SEC14" href="#TOC1">SUBPATTERNS</a><br>
+<P>
+Subpatterns are delimited by parentheses (round brackets), which can be nested.
+Turning part of a pattern into a subpattern does two things:
+<br>
+<br>
+1. It localizes a set of alternatives. For example, the pattern
+<pre>
+ cat(aract|erpillar|)
+</pre>
+matches "cataract", "caterpillar", or "cat". Without the parentheses, it would
+match "cataract", "erpillar" or an empty string.
+<br>
+<br>
+2. It sets up the subpattern as a capturing subpattern. This means that, when
+the whole pattern matches, the portion of the subject string that matched the
+subpattern is passed back to the caller, separately from the portion that
+matched the whole pattern. (This applies only to the traditional matching
+function; the DFA matching function does not support capturing.)
+</P>
+<P>
+Opening parentheses are counted from left to right (starting from 1) to obtain
+numbers for the capturing subpatterns. For example, if the string "the red
+king" is matched against the pattern
+<pre>
+ the ((red|white) (king|queen))
+</pre>
+the captured substrings are "red king", "red", and "king", and are numbered 1,
+2, and 3, respectively.
+</P>
+<P>
+The fact that plain parentheses fulfil two functions is not always helpful.
+There are often times when a grouping subpattern is required without a
+capturing requirement. If an opening parenthesis is followed by a question mark
+and a colon, the subpattern does not do any capturing, and is not counted when
+computing the number of any subsequent capturing subpatterns. For example, if
+the string "the white queen" is matched against the pattern
+<pre>
+ the ((?:red|white) (king|queen))
+</pre>
+the captured substrings are "white queen" and "queen", and are numbered 1 and
+2. The maximum number of capturing subpatterns is 65535.
+</P>
+<P>
+As a convenient shorthand, if any option settings are required at the start of
+a non-capturing subpattern, the option letters may appear between the "?" and
+the ":". Thus the two patterns
+<pre>
+ (?i:saturday|sunday)
+ (?:(?i)saturday|sunday)
+</pre>
+match exactly the same set of strings. Because alternative branches are tried
+from left to right, and options are not reset until the end of the subpattern
+is reached, an option setting in one branch does affect subsequent branches, so
+the above patterns match "SUNDAY" as well as "Saturday".
+<a name="dupsubpatternnumber"></a></P>
+<br><a name="SEC15" href="#TOC1">DUPLICATE SUBPATTERN NUMBERS</a><br>
+<P>
+Perl 5.10 introduced a feature whereby each alternative in a subpattern uses
+the same numbers for its capturing parentheses. Such a subpattern starts with
+(?| and is itself a non-capturing subpattern. For example, consider this
+pattern:
+<pre>
+ (?|(Sat)ur|(Sun))day
+</pre>
+Because the two alternatives are inside a (?| group, both sets of capturing
+parentheses are numbered one. Thus, when the pattern matches, you can look
+at captured substring number one, whichever alternative matched. This construct
+is useful when you want to capture part, but not all, of one of a number of
+alternatives. Inside a (?| group, parentheses are numbered as usual, but the
+number is reset at the start of each branch. The numbers of any capturing
+parentheses that follow the subpattern start after the highest number used in
+any branch. The following example is taken from the Perl documentation. The
+numbers underneath show in which buffer the captured content will be stored.
+<pre>
+ # before ---------------branch-reset----------- after
+ / ( a ) (?| x ( y ) z | (p (q) r) | (t) u (v) ) ( z ) /x
+ # 1 2 2 3 2 3 4
+</pre>
+A back reference to a numbered subpattern uses the most recent value that is
+set for that number by any subpattern. The following pattern matches "abcabc"
+or "defdef":
+<pre>
+ /(?|(abc)|(def))\1/
+</pre>
+In contrast, a subroutine call to a numbered subpattern always refers to the
+first one in the pattern with the given number. The following pattern matches
+"abcabc" or "defabc":
+<pre>
+ /(?|(abc)|(def))(?1)/
+</pre>
+A relative reference such as (?-1) is no different: it is just a convenient way
+of computing an absolute group number.
+</P>
+<P>
+If a
+<a href="#conditions">condition test</a>
+for a subpattern's having matched refers to a non-unique number, the test is
+true if any of the subpatterns of that number have matched.
+</P>
+<P>
+An alternative approach to using this "branch reset" feature is to use
+duplicate named subpatterns, as described in the next section.
+</P>
+<br><a name="SEC16" href="#TOC1">NAMED SUBPATTERNS</a><br>
+<P>
+Identifying capturing parentheses by number is simple, but it can be very hard
+to keep track of the numbers in complicated regular expressions. Furthermore,
+if an expression is modified, the numbers may change. To help with this
+difficulty, PCRE2 supports the naming of subpatterns. This feature was not
+added to Perl until release 5.10. Python had the feature earlier, and PCRE1
+introduced it at release 4.0, using the Python syntax. PCRE2 supports both the
+Perl and the Python syntax. Perl allows identically numbered subpatterns to
+have different names, but PCRE2 does not.
+</P>
+<P>
+In PCRE2, a subpattern can be named in one of three ways: (?<name>...) or
+(?'name'...) as in Perl, or (?P<name>...) as in Python. References to capturing
+parentheses from other parts of the pattern, such as
+<a href="#backreferences">back references,</a>
+<a href="#recursion">recursion,</a>
+and
+<a href="#conditions">conditions,</a>
+can be made by name as well as by number.

+<P>
+Names consist of up to 32 alphanumeric characters and underscores, but must
+start with a non-digit. Named capturing parentheses are still allocated numbers
+as well as names, exactly as if the names were not present. The PCRE2 API
+provides function calls for extracting the name-to-number translation table
+from a compiled pattern. There are also convenience functions for extracting a
+captured substring by name.
+</P>
+<P>
+By default, a name must be unique within a pattern, but it is possible to relax
+this constraint by setting the PCRE2_DUPNAMES option at compile time.
+(Duplicate names are also always permitted for subpatterns with the same
+number, set up as described in the previous section.) Duplicate names can be
+useful for patterns where only one instance of the named parentheses can match.
+Suppose you want to match the name of a weekday, either as a 3-letter
+abbreviation or as the full name, and in both cases you want to extract the
+abbreviation. This pattern (ignoring the line breaks) does the job:
+<pre>
+ (?<DN>Mon|Fri|Sun)(?:day)?|
+ (?<DN>Tue)(?:sday)?|
+ (?<DN>Wed)(?:nesday)?|
+ (?<DN>Thu)(?:rsday)?|
+ (?<DN>Sat)(?:urday)?
+</pre>
+There are five capturing substrings, but only one is ever set after a match.
+(An alternative way of solving this problem is to use a "branch reset"
+subpattern, as described in the previous section.)
+</P>
+<P>
+The convenience functions for extracting the data by name returns the substring
+for the first (and in this example, the only) subpattern of that name that
+matched. This saves searching to find which numbered subpattern it was.
+</P>
+<P>
+If you make a back reference to a non-unique named subpattern from elsewhere in
+the pattern, the subpatterns to which the name refers are checked in the order
+in which they appear in the overall pattern. The first one that is set is used
+for the reference. For example, this pattern matches both "foofoo" and
+"barbar" but not "foobar" or "barfoo":
+<pre>
+ (?:(?<n>foo)|(?<n>bar))\k<n>
+
+</PRE>
+</P>
+<P>
+If you make a subroutine call to a non-unique named subpattern, the one that
+corresponds to the first occurrence of the name is used. In the absence of
+duplicate numbers (see the previous section) this is the one with the lowest
+number.
+</P>
+<P>
+If you use a named reference in a condition
+test (see the
+<a href="#conditions">section about conditions</a>
+below), either to check whether a subpattern has matched, or to check for
+recursion, all subpatterns with the same name are tested. If the condition is
+true for any one of them, the overall condition is true. This is the same
+behaviour as testing by number. For further details of the interfaces for
+handling named subpatterns, see the
+<a href="pcre2api.html"><b>pcre2api</b></a>
+documentation.
+</P>
+<P>
+<b>Warning:</b> You cannot use different names to distinguish between two
+subpatterns with the same number because PCRE2 uses only the numbers when
+matching. For this reason, an error is given at compile time if different names
+are given to subpatterns with the same number. However, you can always give the
+same name to subpatterns with the same number, even when PCRE2_DUPNAMES is not
+set.

+<br><a name="SEC17" href="#TOC1">REPETITION</a><br>
+<P>
+Repetition is specified by quantifiers, which can follow any of the following
+items:
+<pre>
+ a literal data character
+ the dot metacharacter
+ the \C escape sequence
+ the \X escape sequence
+ the \R escape sequence
+ an escape such as \d or \pL that matches a single character
+ a character class
+ a back reference
+ a parenthesized subpattern (including most assertions)
+ a subroutine call to a subpattern (recursive or otherwise)
+</pre>
+The general repetition quantifier specifies a minimum and maximum number of
+permitted matches, by giving the two numbers in curly brackets (braces),
+separated by a comma. The numbers must be less than 65536, and the first must
+be less than or equal to the second. For example:
+<pre>
+ z{2,4}
+</pre>
+matches "zz", "zzz", or "zzzz". A closing brace on its own is not a special
+character. If the second number is omitted, but the comma is present, there is
+no upper limit; if the second number and the comma are both omitted, the
+quantifier specifies an exact number of required matches. Thus
+<pre>
+ [aeiou]{3,}
+</pre>
+matches at least 3 successive vowels, but may match many more, whereas
+<pre>
+ \d{8}
+</pre>
+matches exactly 8 digits. An opening curly bracket that appears in a position
+where a quantifier is not allowed, or one that does not match the syntax of a
+quantifier, is taken as a literal character. For example, {,6} is not a
+quantifier, but a literal string of four characters.
+</P>
+<P>
+In UTF modes, quantifiers apply to characters rather than to individual code
+units. Thus, for example, \x{100}{2} matches two characters, each of
+which is represented by a two-byte sequence in a UTF-8 string. Similarly,
+\X{3} matches three Unicode extended grapheme clusters, each of which may be
+several code units long (and they may be of different lengths).
+</P>
+<P>
+The quantifier {0} is permitted, causing the expression to behave as if the
+previous item and the quantifier were not present. This may be useful for
+subpatterns that are referenced as
+<a href="#subpatternsassubroutines">subroutines</a>
+from elsewhere in the pattern (but see also the section entitled
+<a href="#subdefine">"Defining subpatterns for use by reference only"</a>
+below). Items other than subpatterns that have a {0} quantifier are omitted
+from the compiled pattern.
+</P>
+<P>
+For convenience, the three most common quantifiers have single-character
+abbreviations:
+<pre>
+ * is equivalent to {0,}
+ + is equivalent to {1,}
+ ? is equivalent to {0,1}
+</pre>
+It is possible to construct infinite loops by following a subpattern that can
+match no characters with a quantifier that has no upper limit, for example:
+<pre>
+ (a?)*
+</pre>
+Earlier versions of Perl and PCRE1 used to give an error at compile time for
+such patterns. However, because there are cases where this can be useful, such
+patterns are now accepted, but if any repetition of the subpattern does in fact
+match no characters, the loop is forcibly broken.
+</P>
+<P>
+By default, the quantifiers are "greedy", that is, they match as much as
+possible (up to the maximum number of permitted times), without causing the
+rest of the pattern to fail. The classic example of where this gives problems
+is in trying to match comments in C programs. These appear between /* and */
+and within the comment, individual * and / characters may appear. An attempt to
+match C comments by applying the pattern
+<pre>
+ /\*.*\*/
+</pre>
+to the string
+<pre>
+ /* first comment */ not comment /* second comment */
+</pre>
+fails, because it matches the entire string owing to the greediness of the .*
+item.
+</P>
+<P>
+If a quantifier is followed by a question mark, it ceases to be greedy, and
+instead matches the minimum number of times possible, so the pattern
+<pre>
+ /\*.*?\*/
+</pre>
+does the right thing with the C comments. The meaning of the various
+quantifiers is not otherwise changed, just the preferred number of matches.
+Do not confuse this use of question mark with its use as a quantifier in its
+own right. Because it has two uses, it can sometimes appear doubled, as in
+<pre>
+ \d??\d
+</pre>
+which matches one digit by preference, but can match two if that is the only
+way the rest of the pattern matches.
+</P>
+<P>
+If the PCRE2_UNGREEDY option is set (an option that is not available in Perl),
+the quantifiers are not greedy by default, but individual ones can be made
+greedy by following them with a question mark. In other words, it inverts the
+default behaviour.
+</P>
+<P>
+When a parenthesized subpattern is quantified with a minimum repeat count that
+is greater than 1 or with a limited maximum, more memory is required for the
+compiled pattern, in proportion to the size of the minimum or maximum.
+</P>
+<P>
+If a pattern starts with .* or .{0,} and the PCRE2_DOTALL option (equivalent
+to Perl's /s) is set, thus allowing the dot to match newlines, the pattern is
+implicitly anchored, because whatever follows will be tried against every
+character position in the subject string, so there is no point in retrying the
+overall match at any position after the first. PCRE2 normally treats such a
+pattern as though it were preceded by \A.
+</P>
+<P>
+In cases where it is known that the subject string contains no newlines, it is
+worth setting PCRE2_DOTALL in order to obtain this optimization, or
+alternatively, using ^ to indicate anchoring explicitly.
+</P>
+<P>
+However, there are some cases where the optimization cannot be used. When .*
+is inside capturing parentheses that are the subject of a back reference
+elsewhere in the pattern, a match at the start may fail where a later one
+succeeds. Consider, for example:
+<pre>
+ (.*)abc\1
+</pre>
+If the subject is "xyz123abc123" the match point is the fourth character. For
+this reason, such a pattern is not implicitly anchored.
+</P>
+<P>
+Another case where implicit anchoring is not applied is when the leading .* is
+inside an atomic group. Once again, a match at the start may fail where a later
+one succeeds. Consider this pattern:
+<pre>
+ (?>.*?a)b
+</pre>
+It matches "ab" in the subject "aab". The use of the backtracking control verbs
+(*PRUNE) and (*SKIP) also disable this optimization, and there is an option,
+PCRE2_NO_DOTSTAR_ANCHOR, to do so explicitly.
+</P>
+<P>
+When a capturing subpattern is repeated, the value captured is the substring
+that matched the final iteration. For example, after
+<pre>
+ (tweedle[dume]{3}\s*)+
+</pre>
+has matched "tweedledum tweedledee" the value of the captured substring is
+"tweedledee". However, if there are nested capturing subpatterns, the
+corresponding captured values may have been set in previous iterations. For
+example, after
+<pre>
+ (a|(b))+
+</pre>
+matches "aba" the value of the second captured substring is "b".
+<a name="atomicgroup"></a></P>
+<br><a name="SEC18" href="#TOC1">ATOMIC GROUPING AND POSSESSIVE QUANTIFIERS</a><br>
+<P>
+With both maximizing ("greedy") and minimizing ("ungreedy" or "lazy")
+repetition, failure of what follows normally causes the repeated item to be
+re-evaluated to see if a different number of repeats allows the rest of the
+pattern to match. Sometimes it is useful to prevent this, either to change the
+nature of the match, or to cause it fail earlier than it otherwise might, when
+the author of the pattern knows there is no point in carrying on.
+</P>
+<P>
+Consider, for example, the pattern \d+foo when applied to the subject line
+<pre>
+ 123456bar
+</pre>
+After matching all 6 digits and then failing to match "foo", the normal
+action of the matcher is to try again with only 5 digits matching the \d+
+item, and then with 4, and so on, before ultimately failing. "Atomic grouping"
+(a term taken from Jeffrey Friedl's book) provides the means for specifying
+that once a subpattern has matched, it is not to be re-evaluated in this way.
+</P>
+<P>
+If we use atomic grouping for the previous example, the matcher gives up
+immediately on failing to match "foo" the first time. The notation is a kind of
+special parenthesis, starting with (?> as in this example:
+<pre>
+ (?>\d+)foo
+</pre>
+This kind of parenthesis "locks up" the part of the pattern it contains once
+it has matched, and a failure further into the pattern is prevented from
+backtracking into it. Backtracking past it to previous items, however, works as
+normal.
+</P>
+<P>
+An alternative description is that a subpattern of this type matches exactly
+the string of characters that an identical standalone pattern would match, if
+anchored at the current point in the subject string.
+</P>
+<P>
+Atomic grouping subpatterns are not capturing subpatterns. Simple cases such as
+the above example can be thought of as a maximizing repeat that must swallow
+everything it can. So, while both \d+ and \d+? are prepared to adjust the
+number of digits they match in order to make the rest of the pattern match,
+(?>\d+) can only match an entire sequence of digits.
+</P>
+<P>
+Atomic groups in general can of course contain arbitrarily complicated
+subpatterns, and can be nested. However, when the subpattern for an atomic
+group is just a single repeated item, as in the example above, a simpler
+notation, called a "possessive quantifier" can be used. This consists of an
+additional + character following a quantifier. Using this notation, the
+previous example can be rewritten as
+<pre>
+ \d++foo
+</pre>
+Note that a possessive quantifier can be used with an entire group, for
+example:
+<pre>
+ (abc|xyz){2,3}+
+</pre>
+Possessive quantifiers are always greedy; the setting of the PCRE2_UNGREEDY
+option is ignored. They are a convenient notation for the simpler forms of
+atomic group. However, there is no difference in the meaning of a possessive
+quantifier and the equivalent atomic group, though there may be a performance
+difference; possessive quantifiers should be slightly faster.
+</P>
+<P>
+The possessive quantifier syntax is an extension to the Perl 5.8 syntax.
+Jeffrey Friedl originated the idea (and the name) in the first edition of his
+book. Mike McCloskey liked it, so implemented it when he built Sun's Java
+package, and PCRE1 copied it from there. It ultimately found its way into Perl
+at release 5.10.
+</P>
+<P>
+PCRE2 has an optimization that automatically "possessifies" certain simple
+pattern constructs. For example, the sequence A+B is treated as A++B because
+there is no point in backtracking into a sequence of A's when B must follow.
+This feature can be disabled by the PCRE2_NO_AUTOPOSSESS option, or starting
+the pattern with (*NO_AUTO_POSSESS).
+</P>
+<P>
+When a pattern contains an unlimited repeat inside a subpattern that can itself
+be repeated an unlimited number of times, the use of an atomic group is the
+only way to avoid some failing matches taking a very long time indeed. The
+pattern
+<pre>
+ (\D+|<\d+>)*[!?]
+</pre>
+matches an unlimited number of substrings that either consist of non-digits, or
+digits enclosed in <>, followed by either ! or ?. When it matches, it runs
+quickly. However, if it is applied to
+<pre>
+ aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
+</pre>
+it takes a long time before reporting failure. This is because the string can
+be divided between the internal \D+ repeat and the external * repeat in a
+large number of ways, and all have to be tried. (The example uses [!?] rather
+than a single character at the end, because both PCRE2 and Perl have an
+optimization that allows for fast failure when a single character is used. They
+remember the last single character that is required for a match, and fail early
+if it is not present in the string.) If the pattern is changed so that it uses
+an atomic group, like this:
+<pre>
+ ((?>\D+)|<\d+>)*[!?]
+</pre>
+sequences of non-digits cannot be broken, and failure happens quickly.
+<a name="backreferences"></a></P>
+<br><a name="SEC19" href="#TOC1">BACK REFERENCES</a><br>
+<P>
+Outside a character class, a backslash followed by a digit greater than 0 (and
+possibly further digits) is a back reference to a capturing subpattern earlier
+(that is, to its left) in the pattern, provided there have been that many
+previous capturing left parentheses.
+</P>
+<P>
+However, if the decimal number following the backslash is less than 8, it is
+always taken as a back reference, and causes an error only if there are not
+that many capturing left parentheses in the entire pattern. In other words, the
+parentheses that are referenced need not be to the left of the reference for
+numbers less than 8. A "forward back reference" of this type can make sense
+when a repetition is involved and the subpattern to the right has participated
+in an earlier iteration.
+</P>
+<P>
+It is not possible to have a numerical "forward back reference" to a subpattern
+whose number is 8 or more using this syntax because a sequence such as \50 is
+interpreted as a character defined in octal. See the subsection entitled
+"Non-printing characters"
+<a href="#digitsafterbackslash">above</a>
+for further details of the handling of digits following a backslash. There is
+no such problem when named parentheses are used. A back reference to any
+subpattern is possible using named parentheses (see below).
+</P>
+<P>
+Another way of avoiding the ambiguity inherent in the use of digits following a
+backslash is to use the \g escape sequence. This escape must be followed by an
+unsigned number or a negative number, optionally enclosed in braces. These
+examples are all identical:
+<pre>
+ (ring), \1
+ (ring), \g1
+ (ring), \g{1}
+</pre>
+An unsigned number specifies an absolute reference without the ambiguity that
+is present in the older syntax. It is also useful when literal digits follow
+the reference. A negative number is a relative reference. Consider this
+example:
+<pre>
+ (abc(def)ghi)\g{-1}
+</pre>
+The sequence \g{-1} is a reference to the most recently started capturing
+subpattern before \g, that is, is it equivalent to \2 in this example.
+Similarly, \g{-2} would be equivalent to \1. The use of relative references
+can be helpful in long patterns, and also in patterns that are created by
+joining together fragments that contain references within themselves.
+</P>
+<P>
+A back reference matches whatever actually matched the capturing subpattern in
+the current subject string, rather than anything matching the subpattern
+itself (see
+<a href="#subpatternsassubroutines">"Subpatterns as subroutines"</a>
+below for a way of doing that). So the pattern
+<pre>
+ (sens|respons)e and \1ibility
+</pre>
+matches "sense and sensibility" and "response and responsibility", but not
+"sense and responsibility". If caseful matching is in force at the time of the
+back reference, the case of letters is relevant. For example,
+<pre>
+ ((?i)rah)\s+\1
+</pre>
+matches "rah rah" and "RAH RAH", but not "RAH rah", even though the original
+capturing subpattern is matched caselessly.
+</P>
+<P>
+There are several different ways of writing back references to named
+subpatterns. The .NET syntax \k{name} and the Perl syntax \k<name> or
+\k'name' are supported, as is the Python syntax (?P=name). Perl 5.10's unified
+back reference syntax, in which \g can be used for both numeric and named
+references, is also supported. We could rewrite the above example in any of
+the following ways:
+<pre>
+ (?<p1>(?i)rah)\s+\k<p1>
+ (?'p1'(?i)rah)\s+\k{p1}
+ (?P<p1>(?i)rah)\s+(?P=p1)
+ (?<p1>(?i)rah)\s+\g{p1}
+</pre>
+A subpattern that is referenced by name may appear in the pattern before or
+after the reference.
+</P>
+<P>
+There may be more than one back reference to the same subpattern. If a
+subpattern has not actually been used in a particular match, any back
+references to it always fail by default. For example, the pattern
+<pre>
+ (a|(bc))\2
+</pre>
+always fails if it starts to match "a" rather than "bc". However, if the
+PCRE2_MATCH_UNSET_BACKREF option is set at compile time, a back reference to an
+unset value matches an empty string.
+</P>
+<P>
+Because there may be many capturing parentheses in a pattern, all digits
+following a backslash are taken as part of a potential back reference number.
+If the pattern continues with a digit character, some delimiter must be used to
+terminate the back reference. If the PCRE2_EXTENDED option is set, this can be
+white space. Otherwise, the \g{ syntax or an empty comment (see
+<a href="#comments">"Comments"</a>
+below) can be used.
+</P>
+<br><b>
+Recursive back references
+</b><br>
+<P>
+A back reference that occurs inside the parentheses to which it refers fails
+when the subpattern is first used, so, for example, (a\1) never matches.
+However, such references can be useful inside repeated subpatterns. For
+example, the pattern
+<pre>
+ (a|b\1)+
+</pre>
+matches any number of "a"s and also "aba", "ababbaa" etc. At each iteration of
+the subpattern, the back reference matches the character string corresponding
+to the previous iteration. In order for this to work, the pattern must be such
+that the first iteration does not need to match the back reference. This can be
+done using alternation, as in the example above, or by a quantifier with a
+minimum of zero.
+</P>
+<P>
+Back references of this type cause the group that they reference to be treated

+<P>
+More complicated assertions are coded as subpatterns. There are two kinds:

+except that it does not cause the current matching position to be changed.
+</P>
+<P>
+Assertion subpatterns are not capturing subpatterns. If such an assertion
+contains capturing subpatterns within it, these are counted for the purposes of
+numbering the capturing subpatterns in the whole pattern. However, substring
+capturing is carried out only for positive assertions. (Perl sometimes, but not
+always, does do capturing in negative assertions.)
+</P>
+<P>
+For compatibility with Perl, most assertion subpatterns may be repeated; though
+it makes no sense to assert the same thing several times, the side effect of
+capturing parentheses may occasionally be useful. However, an assertion that
+forms the condition for a conditional subpattern may not be quantified. In
+practice, for other assertions, there only three cases:
+<br>
+<br>
+(1) If the quantifier is {0}, the assertion is never obeyed during matching.
+However, it may contain internal capturing parenthesized groups that are called
+from elsewhere via the
+<a href="#subpatternsassubroutines">subroutine mechanism.</a>
+<br>
+<br>
+(2) If quantifier is {0,n} where n is greater than zero, it is treated as if it
+were {0,1}. At run time, the rest of the pattern match is tried with and
+without the assertion, the order depending on the greediness of the quantifier.
+<br>
+<br>
+(3) If the minimum repetition is greater than zero, the quantifier is ignored.
+The assertion is obeyed just once when encountered during matching.
+</P>
+<br><b>
+Lookahead assertions
+</b><br>
+<P>
+Lookahead assertions start with (?= for positive assertions and (?! for
+negative assertions. For example,

+ \w+(?=;)
+</pre>
+matches a word followed by a semicolon, but does not include the semicolon in
+the match, and
+<pre>
+ foo(?!bar)
+</pre>
+matches any occurrence of "foo" that is not followed by "bar". Note that the
+apparently similar pattern
+<pre>
+ (?!foo)bar
+</pre>
+does not find an occurrence of "bar" that is preceded by something other than
+"foo"; it finds any occurrence of "bar" whatsoever, because the assertion
+(?!foo) is always true when the next three characters are "bar". A
+lookbehind assertion is needed to achieve the other effect.
+</P>
+<P>
+If you want to force a matching failure at some point in a pattern, the most
+convenient way to do it is with (?!) because an empty string always matches, so
+an assertion that requires there not to be an empty string must always fail.

+<a name="lookbehind"></a></P>
+<br><b>
+Lookbehind assertions

+Lookbehind assertions start with (?<= for positive assertions and (?<! for
+negative assertions. For example,
+<pre>
+ (?<!foo)bar
+</pre>
+does find an occurrence of "bar" that is not preceded by "foo". The contents of
+a lookbehind assertion are restricted such that all the strings it matches must
+have a fixed length. However, if there are several top-level alternatives, they
+do not all have to have the same fixed length. Thus
+<pre>
+ (?<=bullock|donkey)
+</pre>
+is permitted, but
+<pre>
+ (?<!dogs?|cats?)
+</pre>
+causes an error at compile time. Branches that match different length strings
+are permitted only at the top level of a lookbehind assertion. This is an
+extension compared with Perl, which requires all branches to match the same
+length of string. An assertion such as
+<pre>
+ (?<=ab(c|de))
+</pre>
+is not permitted, because its single top-level branch can match two different
+lengths, but it is acceptable to PCRE2 if rewritten to use two top-level
+branches:
+<pre>
+ (?<=abc|abde)
+</pre>
+In some cases, the escape sequence \K
+<a href="#resetmatchstart">(see above)</a>
+can be used instead of a lookbehind assertion to get round the fixed-length
+restriction.

+The implementation of lookbehind assertions is, for each alternative, to
+temporarily move the current position back by the fixed length and then try to
+match. If there are insufficient characters before the current position, the

+</P>
+<P>
+In a UTF mode, PCRE2 does not allow the \C escape (which matches a single code
+unit even in a UTF mode) to appear in lookbehind assertions, because it makes
+it impossible to calculate the length of the lookbehind. The \X and \R
+escapes, which can match different numbers of code units, are also not
+permitted.
+</P>
+<P>
+<a href="#subpatternsassubroutines">"Subroutine"</a>

+Possessive quantifiers can be used in conjunction with lookbehind assertions to

+when applied to a long string that does not match. Because matching proceeds
+from left to right, PCRE2 will look for each "a" in the subject and then see if
+what follows matches the rest of the pattern. If the pattern is specified as
+<pre>
+ ^.*abcd$
+</pre>
+the initial .* matches the entire string at first, but when this fails (because
+there is no following "a"), it backtracks to match all but the last character,
+then all but the last two characters, and so on. Once again the search for "a"
+covers the entire string, from right to left, so we are no better off. However,
+if the pattern is written as
+<pre>
+ ^.*+(?<=abcd)
+</pre>
+there can be no backtracking for the .*+ item because of the possessive

+assertion does a single test on the last four characters. If it fails, the
+match fails immediately. For long strings, this approach makes a significant
+difference to the processing time.
+</P>
+<br><b>
+Using multiple assertions
+</b><br>
+<P>
+Several assertions (of any sort) may occur in succession. For example,
+<pre>
+ (?<=\d{3})(?<!999)foo
+</pre>
+matches "foo" preceded by three digits that are not "999". Notice that each of
+the assertions is applied independently at the same point in the subject
+string. First there is a check that the previous three characters are all
+digits, and then there is a check that the same three characters are not "999".
+This pattern does <i>not</i> match "foo" preceded by six characters, the first
+of which are digits and the last three of which are not "999". For example, it
+doesn't match "123abcfoo". A pattern to do that is
+<pre>
+ (?<=\d{3}...)(?<!999)foo
+</pre>
+This time the first assertion looks at the preceding six characters, checking
+that the first three are digits, and then the second assertion checks that the
+preceding three characters are not "999".
+</P>
+<P>
+Assertions can be nested in any combination. For example,
+<pre>
+ (?<=(?<!foo)bar)baz
+</pre>
+matches an occurrence of "baz" that is preceded by "bar" which in turn is not
+preceded by "foo", while
+<pre>
+ (?<=\d{3}(?!999)...)foo
+</pre>
+is another pattern that matches "foo" preceded by three digits and any three
+characters that are not "999".

+It is possible to cause the matching process to obey a subpattern
+conditionally or to choose between two alternative subpatterns, depending on
+the result of an assertion, or whether a specific capturing subpattern has
+already been matched. The two possible forms of conditional subpattern are:
+<pre>
+ (?(condition)yes-pattern)
+ (?(condition)yes-pattern|no-pattern)
+</pre>
+If the condition is satisfied, the yes-pattern is used; otherwise the
+no-pattern (if present) is used. If there are more than two alternatives in the
+subpattern, a compile-time error occurs. Each of the two alternatives may
+itself contain nested subpatterns of any form, including conditional
+subpatterns; the restriction to two alternatives applies only at the level of
+the condition. This pattern fragment is an example where the alternatives are
+complex:
+<pre>
+ (?(1) (A|B|C) | (D | (?(2)E|F) | E) )
+
+</PRE>
+</P>

+There are five kinds of condition: references to subpatterns, references to

+Checking for a used subpattern by number

+If the text between the parentheses consists of a sequence of digits, the

+(see the earlier

+the condition is true if any of them have matched. An alternative notation is
+to precede the digits with a plus or minus sign. In this case, the subpattern
+number is relative rather than absolute. The most recently opened parentheses
+can be referenced by (?(-1), the next most recent by (?(-2), and so on. Inside
+loops it can also make sense to refer to subsequent groups. The next
+parentheses to be opened can be referenced as (?(+1), and so on. (The value
+zero in any of these forms is not used; it provokes a compile-time error.)

+Consider the following pattern, which contains non-significant white space to

+three parts for ease of discussion:

+</pre>
+The first part matches an optional opening parenthesis, and if that
+character is present, sets it as the first captured substring. The second part
+matches one or more characters that are not parentheses. The third part is a
+conditional subpattern that tests whether or not the first set of parentheses
+matched. If they did, that is, if subject started with an opening parenthesis,
+the condition is true, and so the yes-pattern is executed and a closing
+parenthesis is required. Otherwise, since no-pattern is not present, the
+subpattern matches nothing. In other words, this pattern matches a sequence of
+non-parentheses, optionally enclosed in parentheses.
+</P>
+<P>
+If you were embedding this pattern in a larger one, you could use a relative

+Defining subpatterns for use by reference only

+<P>
+If the condition is the string (DEFINE), and there is no subpattern with the

+alternative in the subpattern. It is always skipped if control reaches this
+point in the pattern; the idea of DEFINE is that it can be used to define
+subroutines that can be referenced from elsewhere. (The use of
+<a href="#subpatternsassubroutines">subroutines</a>
+is described below.) For example, a pattern to match an IPv4 address such as
+"192.168.23.245" could be written like this (ignore white space and line

+<pre>
+ (?(DEFINE) (?<byte> 2[0-4]\d | 25[0-5] | 1\d\d | [1-9]?\d) )
+ \b (?&byte) (\.(?&byte)){3} \b
+</pre>
+The first part of the pattern is a DEFINE group inside which a another group
+named "byte" is defined. This matches an individual component of an IPv4
+address (a number less than 256). When matching takes place, this part of the
+pattern is skipped because DEFINE acts like a false condition. The rest of the
+pattern uses references to the named group to match the four dot-separated
+components of an IPv4 address, insisting on a word boundary at each end.
+</P>
+<br><b>
+Checking the PCRE2 version
+</b><br>
+<P>
+Programs that link with a PCRE2 library can check the version by calling
+<b>pcre2_config()</b> with appropriate arguments. Users of applications that do
+not have access to the underlying code cannot do this. A special "condition"
+called VERSION exists to allow such users to discover which version of PCRE2
+they are dealing with by using this condition to match a string such as
+"yesno". VERSION must be followed either by "=" or ">=" and a version number.
+For example:
+<pre>
+ (?(VERSION>=10.4)yes|no)
+</pre>
+This pattern matches "yes" if the PCRE2 version is greater or equal to 10.4, or
+"no" otherwise. The fractional part of the version number may not contain more
+than two digits.
+</P>
+<br><b>
+Assertion conditions
+</b><br>
+<P>
+If the condition is not in any of the above formats, it must be an assertion.
+This may be a positive or negative lookahead or lookbehind assertion. Consider
+this pattern, again containing non-significant white space, and with the two
+alternatives on the second line:
+<pre>
+ (?(?=[^a-z]*[a-z])
+ \d{2}-[a-z]{3}-\d{2} | \d{2}-\d{2}-\d{2} )
+</pre>
+The condition is a positive lookahead assertion that matches an optional
+sequence of non-letters followed by a letter. In other words, it tests for the
+presence of at least one letter in the subject. If a letter is found, the
+subject is matched against the first alternative; otherwise it is matched
+against the second. This pattern matches strings in one of the two forms
+dd-aaa-dd or dd-dd-dd, where aaa are letters and dd are digits.
+<a name="comments"></a></P>
+<br><a name="SEC22" href="#TOC1">COMMENTS</a><br>
+<P>
+There are two ways of including comments in patterns that are processed by
+PCRE2. In both cases, the start of the comment must not be in a character
+class, nor in the middle of any other sequence of related characters such as
+(?: or a subpattern name or number. The characters that make up a comment play
+no part in the pattern matching.
+</P>
+<P>
+The sequence (?# marks the start of a comment that continues up to the next
+closing parenthesis. Nested parentheses are not permitted. If the
+PCRE2_EXTENDED option is set, an unescaped # character also introduces a
+comment, which in this case continues to immediately after the next newline
+character or character sequence in the pattern. Which characters are
+interpreted as newlines is controlled by an option passed to the compiling
+function or by a special sequence at the start of the pattern, as described in
+the section entitled
+<a href="#newlines">"Newline conventions"</a>
+above. Note that the end of this type of comment is a literal newline sequence
+in the pattern; escape sequences that happen to represent a newline do not
+count. For example, consider this pattern when PCRE2_EXTENDED is set, and the
+default newline convention (a single linefeed character) is in force:
+<pre>
+ abc #comment \n still comment
+</pre>
+On encountering the # character, <b>pcre2_compile()</b> skips along, looking for
+a newline in the pattern. The sequence \n is still literal at this stage, so
+it does not terminate the comment. Only an actual character with the code value
+0x0a (the default newline) does so.

+is not possible to handle an arbitrary nesting depth.
+</P>
+<P>
+For some time, Perl has provided a facility that allows regular expressions to
+recurse (amongst other things). It does this by interpolating Perl code in the
+expression at run time, and the code can refer to the expression itself. A Perl
+pattern using code interpolation to solve the parentheses problem can be
+created like this:
+<pre>
+ $re = qr{\( (?: (?>[^()]+) | (?p{$re}) )* \)}x;
+</pre>
+The (?p{...}) item interpolates Perl code at run time, and in this case refers
+recursively to the pattern in which it appears.
+</P>
+<P>
+Obviously, PCRE2 cannot support the interpolation of Perl code. Instead, it
+supports special syntax for recursion of the entire pattern, and also for
+individual subpattern recursion. After its introduction in PCRE1 and Python,
+this kind of recursion was subsequently introduced into Perl at release 5.10.
+</P>
+<P>
+A special item that consists of (? followed by a number greater than zero and a
+closing parenthesis is a recursive subroutine call of the subpattern of the
+given number, provided that it occurs inside that subpattern. (If not, it is a
+<a href="#subpatternsassubroutines">non-recursive subroutine</a>
+call, which is described in the next section.) The special item (?R) or (?0) is
+a recursive call of the entire regular expression.
+</P>
+<P>
+This PCRE2 pattern solves the nested parentheses problem (assume the
+PCRE2_EXTENDED option is set so that white space is ignored):
+<pre>
+ \( ( [^()]++ | (?R) )* \)
+</pre>
+First it matches an opening parenthesis. Then it matches any number of
+substrings which can either be a sequence of non-parentheses, or a recursive
+match of the pattern itself (that is, a correctly parenthesized substring).
+Finally there is a closing parenthesis. Note the use of a possessive quantifier
+to avoid backtracking into sequences of non-parentheses.
+</P>
+<P>
+If this were part of a larger pattern, you would not want to recurse the entire
+pattern, so instead you could use this:
+<pre>
+ ( \( ( [^()]++ | (?1) )* \) )
+</pre>
+We have put the pattern into parentheses, and caused the recursion to refer to
+them instead of the whole pattern.
+</P>
+<P>
+In a larger pattern, keeping track of parenthesis numbers can be tricky. This
+is made easier by the use of relative references. Instead of (?1) in the
+pattern above you can write (?-2) to refer to the second most recently opened
+parentheses preceding the recursion. In other words, a negative number counts
+capturing parentheses leftwards from the point at which it is encountered.
+</P>
+<P>
+Be aware however, that if
+<a href="#dupsubpatternnumber">duplicate subpattern numbers</a>
+are in use, relative references refer to the earliest subpattern with the
+appropriate number. Consider, for example:
+<pre>
+ (?|(a)|(b)) (c) (?-2)
+</pre>
+The first two capturing groups (a) and (b) are both numbered 1, and group (c)
+is number 2. When the reference (?-2) is encountered, the second most recently
+opened parentheses has the number 1, but it is the first such group (the (a)
+group) to which the recursion refers. This would be the same if an absolute
+reference (?1) was used. In other words, relative references are just a
+shorthand for computing a group number.
+</P>
+<P>
+It is also possible to refer to subsequently opened parentheses, by writing
+references such as (?+2). However, these cannot be recursive because the
+reference is not inside the parentheses that are referenced. They are always
+<a href="#subpatternsassubroutines">non-recursive subroutine</a>
+calls, as described in the next section.
+</P>
+<P>
+An alternative approach is to use named parentheses. The Perl syntax for this
+is (?&name); PCRE1's earlier syntax (?P>name) is also supported. We could
+rewrite the above example as follows:
+<pre>
+ (?<pn> \( ( [^()]++ | (?&pn) )* \) )
+</pre>
+If there is more than one subpattern with the same name, the earliest one is
+used.
+</P>
+<P>
+The example pattern that we have been looking at contains nested unlimited
+repeats, and so the use of a possessive quantifier for matching strings of
+non-parentheses is important when applying the pattern to strings that do not
+match. For example, when this pattern is applied to
+<pre>
+ (aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa()
+</pre>
+it yields "no match" quickly. However, if a possessive quantifier is not used,
+the match runs for a very long time indeed because there are so many different
+ways the + and * repeats can carve up the subject, and all have to be tested
+before failure can be reported.
+</P>
+<P>
+At the end of a match, the values of capturing parentheses are those from
+the outermost level. If you want to obtain intermediate values, a callout
+function can be used (see below and the
+<a href="pcre2callout.html"><b>pcre2callout</b></a>
+documentation). If the pattern above is matched against
+<pre>
+ (ab(cd)ef)
+</pre>
+the value for the inner capturing parentheses (numbered 2) is "ef", which is
+the last value taken on at the top level. If a capturing subpattern is not
+matched at the top level, its final captured value is unset, even if it was
+(temporarily) set at a deeper level during the matching process.
+</P>
+<P>
+If there are more than 15 capturing parentheses in a pattern, PCRE2 has to
+obtain extra memory from the heap to store data during a recursion. If no
+memory can be obtained, the match fails with the PCRE2_ERROR_NOMEMORY error.
+</P>
+<P>
+Do not confuse the (?R) item with the condition (R), which tests for recursion.
+Consider this pattern, which matches text in angle brackets, allowing for
+arbitrary nesting. Only digits are allowed in nested brackets (that is, when
+recursing), whereas any characters are permitted at the outer level.
+<pre>
+ < (?: (?(R) \d++ | [^<>]*+) | (?R)) * >
+</pre>
+In this pattern, (?(R) is the start of a conditional subpattern, with two
+different alternatives for the recursive and non-recursive cases. The (?R) item
+is the actual recursive call.
+<a name="recursiondifference"></a></P>
+<br><b>
+Differences in recursion processing between PCRE2 and Perl
+</b><br>
+<P>
+Recursion processing in PCRE2 differs from Perl in two important ways. In PCRE2
+(like Python, but unlike Perl), a recursive subpattern call is always treated
+as an atomic group. That is, once it has matched some of the subject string, it
+is never re-entered, even if it contains untried alternatives and there is a
+subsequent matching failure. This can be illustrated by the following pattern,
+which purports to match a palindromic string that contains an odd number of
+characters (for example, "a", "aba", "abcba", "abcdcba"):
+<pre>
+ ^(.|(.)(?1)\2)$
+</pre>
+The idea is that it either matches a single character, or two identical
+characters surrounding a sub-palindrome. In Perl, this pattern works; in PCRE2
+it does not if the pattern is longer than three characters. Consider the
+subject string "abcba":
+</P>
+<P>
+At the top level, the first character is matched, but as it is not at the end
+of the string, the first alternative fails; the second alternative is taken
+and the recursion kicks in. The recursive call to subpattern 1 successfully
+matches the next character ("b"). (Note that the beginning and end of line
+tests are not part of the recursion).
+</P>
+<P>
+Back at the top level, the next character ("c") is compared with what
+subpattern 2 matched, which was "a". This fails. Because the recursion is
+treated as an atomic group, there are now no backtracking points, and so the
+entire match fails. (Perl is able, at this point, to re-enter the recursion and
+try the second alternative.) However, if the pattern is written with the
+alternatives in the other order, things are different:
+<pre>
+ ^((.)(?1)\2|.)$
+</pre>
+This time, the recursing alternative is tried first, and continues to recurse
+until it runs out of characters, at which point the recursion fails. But this
+time we do have another alternative to try at the higher level. That is the big
+difference: in the previous case the remaining alternative is at a deeper
+recursion level, which PCRE2 cannot use.
+</P>
+<P>
+To change the pattern so that it matches all palindromic strings, not just
+those with an odd number of characters, it is tempting to change the pattern to
+this:
+<pre>
+ ^((.)(?1)\2|.?)$
+</pre>
+Again, this works in Perl, but not in PCRE2, and for the same reason. When a
+deeper recursion has matched a single character, it cannot be entered again in
+order to match an empty string. The solution is to separate the two cases, and
+write out the odd and even cases as alternatives at the higher level:
+<pre>
+ ^(?:((.)(?1)\2|)|((.)(?3)\4|.))
+</pre>
+If you want to match typical palindromic phrases, the pattern has to ignore all
+non-word characters, which can be done like this:
+<pre>
+ ^\W*+(?:((.)\W*+(?1)\W*+\2|)|((.)\W*+(?3)\W*+\4|\W*+.\W*+))\W*+$
+</pre>
+If run with the PCRE2_CASELESS option, this pattern matches phrases such as "A
+man, a plan, a canal: Panama!" and it works in both PCRE2 and Perl. Note the
+use of the possessive quantifier *+ to avoid backtracking into sequences of
+non-word characters. Without this, PCRE2 takes a great deal longer (ten times
+or more) to match typical phrases, and Perl takes so long that you think it has
+gone into a loop.
+</P>
+<P>
+<b>WARNING</b>: The palindrome-matching patterns above work only if the subject
+string does not start with a palindrome that is shorter than the entire string.
+For example, although "abcba" is correctly matched, if the subject is "ababa",
+PCRE2 finds the palindrome "aba" at the start, then fails at top level because
+the end of the string does not follow. Once again, it cannot jump back into the
+recursion to try other alternatives, so the entire match fails.
+</P>
+<P>
+The second way in which PCRE2 and Perl differ in their recursion processing is
+in the handling of captured values. In Perl, when a subpattern is called
+recursively or as a subpattern (see the next section), it has no access to any
+values that were captured outside the recursion, whereas in PCRE2 these values
+can be referenced. Consider this pattern:
+<pre>
+ ^(.)(\1|a(?2))
+</pre>
+In PCRE2, this pattern matches "bab". The first capturing parentheses match "b",
+then in the second group, when the back reference \1 fails to match "b", the
+second alternative matches "a" and then recurses. In the recursion, \1 does
+now match "b" and so the whole match succeeds. In Perl, the pattern fails to
+match because inside the recursive call \1 cannot access the externally set
+value.
+<a name="subpatternsassubroutines"></a></P>
+<br><a name="SEC24" href="#TOC1">SUBPATTERNS AS SUBROUTINES</a><br>
+<P>
+If the syntax for a recursive subpattern call (either by number or by
+name) is used outside the parentheses to which it refers, it operates like a
+subroutine in a programming language. The called subpattern may be defined
+before or after the reference. A numbered reference can be absolute or
+relative, as in these examples:
+<pre>
+ (...(absolute)...)...(?2)...
+ (...(relative)...)...(?-1)...
+ (...(?+1)...(relative)...
+</pre>
+An earlier example pointed out that the pattern
+<pre>
+ (sens|respons)e and \1ibility
+</pre>
+matches "sense and sensibility" and "response and responsibility", but not
+"sense and responsibility". If instead the pattern
+<pre>
+ (sens|respons)e and (?1)ibility
+</pre>
+is used, it does match "sense and responsibility" as well as the other two
+strings. Another example is given in the discussion of DEFINE above.
+</P>
+<P>
+All subroutine calls, whether recursive or not, are always treated as atomic
+groups. That is, once a subroutine has matched some of the subject string, it
+is never re-entered, even if it contains untried alternatives and there is a
+subsequent matching failure. Any capturing parentheses that are set during the
+subroutine call revert to their previous values afterwards.
+</P>
+<P>
+Processing options such as case-independence are fixed when a subpattern is
+defined, so if it is used as a subroutine, such options cannot be changed for
+different calls. For example, consider this pattern:
+<pre>
+ (abc)(?i:(?-1))
+</pre>
+It matches "abcabc". It does not match "abcABC" because the change of
+processing option does not affect the called subpattern.

+For compatibility with Oniguruma, the non-Perl syntax \g followed by a name or

+ (abc)(?i:\g<-1>)

+Note that \g{...} (Perl syntax) and \g<...> (Oniguruma syntax) are <i>not</i>

+<br><a name="SEC26" href="#TOC1">CALLOUTS</a><br>
+<P>
+Perl has a feature whereby using the sequence (?{...}) causes arbitrary Perl
+code to be obeyed in the middle of matching a regular expression. This makes it
+possible, amongst other things, to extract different substrings that match the
+same pair of parentheses when there is a repetition.
+</P>
+<P>
+PCRE2 provides a similar feature, but of course it cannot obey arbitrary Perl
+code. The feature is called "callout". The caller of PCRE2 provides an external
+function by putting its entry point in a match context using the function
+<b>pcre2_set_callout()</b>, and then passing that context to <b>pcre2_match()</b>
+or <b>pcre2_dfa_match()</b>. If no match context is passed, or if the callout
+entry point is set to NULL, callouts are disabled.
+</P>
+<P>
+Within a regular expression, (?C<arg>) indicates a point at which the external
+function is to be called. There are two kinds of callout: those with a
+numerical argument and those with a string argument. (?C) on its own with no
+argument is treated as (?C0). A numerical argument allows the application to
+distinguish between different callouts. String arguments were added for release
+10.20 to make it possible for script languages that use PCRE2 to embed short
+scripts within patterns in a similar way to Perl.
+</P>
+<P>
+During matching, when PCRE2 reaches a callout point, the external function is
+called. It is provided with the number or string argument of the callout, the
+position in the pattern, and one item of data that is also set in the match
+block. The callout function may cause matching to proceed, to backtrack, or to
+fail.
+</P>
+<P>
+By default, PCRE2 implements a number of optimizations at matching time, and
+one side-effect is that sometimes callouts are skipped. If you need all
+possible callouts to happen, you need to set options that disable the relevant
+optimizations. More details, including a complete description of the
+programming interface to the callout function, are given in the
+<a href="pcre2callout.html"><b>pcre2callout</b></a>
+documentation.

+<br><b>
+Callouts with numerical arguments
+</b><br>
+<P>
+If you just want to have a means of identifying different callout points, put a
+number less than 256 after the letter C. For example, this pattern has two
+callout points:
+<pre>
+ (?C1)abc(?C2)def
+</pre>
+If the PCRE2_AUTO_CALLOUT flag is passed to <b>pcre2_compile()</b>, numerical
+callouts are automatically installed before each item in the pattern. They are
+all numbered 255. If there is a conditional group in the pattern whose
+condition is an assertion, an additional callout is inserted just before the
+condition. An explicit callout may also be set at this position, as in this
+example:
+<pre>
+ (?(?C9)(?=a)abc|def)
+</pre>
+Note that this applies only to assertion conditions, not to other types of
+condition.
+</P>
+<br><b>
+Callouts with string arguments
+</b><br>
+<P>
+A delimited string may be used instead of a number as a callout argument. The
+starting delimiter must be one of ` ' " ^ % # $ { and the ending delimiter is
+the same as the start, except for {, where the ending delimiter is }. If the
+ending delimiter is needed within the string, it must be doubled. For
+example:
+<pre>
+ (?C'ab ''c'' d')xyz(?C{any text})pqr
+</pre>
+The doubling is removed before the string is passed to the callout function.

+<br><a name="SEC27" href="#TOC1">BACKTRACKING CONTROL</a><br>
+<P>
+Perl 5.10 introduced a number of "Special Backtracking Control Verbs", which
+are still described in the Perl documentation as "experimental and subject to
+change or removal in a future version of Perl". It goes on to say: "Their usage
+in production code should be noted to avoid problems during upgrades." The same
+remarks apply to the PCRE2 features described in this section.
+</P>
+<P>
+The new verbs make use of what was previously invalid syntax: an opening
+parenthesis followed by an asterisk. They are generally of the form (*VERB) or
+(*VERB:NAME). Some verbs take either form, possibly behaving differently
+depending on whether or not a name is present.
+</P>
+<P>
+By default, for compatibility with Perl, a name is any sequence of characters
+that does not include a closing parenthesis. The name is not processed in
+any way, and it is not possible to include a closing parenthesis in the name.
+However, if the PCRE2_ALT_VERBNAMES option is set, normal backslash processing
+is applied to verb names and only an unescaped closing parenthesis terminates
+the name. A closing parenthesis can be included in a name either as \) or
+between \Q and \E. If the PCRE2_EXTENDED option is set, unescaped whitespace
+in verb names is skipped and #-comments are recognized, exactly as in the rest
+of the pattern.
+</P>
+<P>
+The maximum length of a name is 255 in the 8-bit library and 65535 in the
+16-bit and 32-bit libraries. If the name is empty, that is, if the closing
+parenthesis immediately follows the colon, the effect is as if the colon were
+not there. Any number of these verbs may occur in a pattern.
+</P>
+<P>
+Since these verbs are specifically related to backtracking, most of them can be
+used only when the pattern is to be matched using the traditional matching
+function, because these use a backtracking algorithm. With the exception of
+(*FAIL), which behaves like a failing negative assertion, the backtracking
+control verbs cause an error if encountered by the DFA matching function.
+</P>
+<P>
+The behaviour of these verbs in
+<a href="#btrepeat">repeated groups,</a>
+<a href="#btassert">assertions,</a>
+and in
+<a href="#btsub">subpatterns called as subroutines</a>
+(whether or not recursively) is documented below.
+<a name="nooptimize"></a></P>
+<br><b>
+Optimizations that affect backtracking verbs
+</b><br>
+<P>
+PCRE2 contains some optimizations that are used to speed up matching by running
+some checks at the start of each match attempt. For example, it may know the
+minimum length of matching subject, or that a particular character must be
+present. When one of these optimizations bypasses the running of a match, any
+included backtracking verbs will not, of course, be processed. You can suppress
+the start-of-match optimizations by setting the PCRE2_NO_START_OPTIMIZE option
+when calling <b>pcre2_compile()</b>, or by starting the pattern with
+(*NO_START_OPT). There is more discussion of this option in the section
+entitled
+<a href="pcre2api.html#compiling">"Compiling a pattern"</a>
+in the
+<a href="pcre2api.html"><b>pcre2api</b></a>
+documentation.
+</P>
+<P>
+Experiments with Perl suggest that it too has similar optimizations, sometimes
+leading to anomalous results.
+</P>
+<br><b>
+Verbs that act immediately
+</b><br>
+<P>
+The following verbs act as soon as they are encountered. They may not be
+followed by a name.
+<pre>
+ (*ACCEPT)
+</pre>
+This verb causes the match to end successfully, skipping the remainder of the
+pattern. However, when it is inside a subpattern that is called as a
+subroutine, only that subpattern is ended successfully. Matching then continues
+at the outer level. If (*ACCEPT) in triggered in a positive assertion, the
+assertion succeeds; in a negative assertion, the assertion fails.
+</P>
+<P>
+If (*ACCEPT) is inside capturing parentheses, the data so far is captured. For
+example:
+<pre>
+ A((?:A|B(*ACCEPT)|C)D)
+</pre>
+This matches "AB", "AAD", or "ACD"; when it matches "AB", "B" is captured by
+the outer parentheses.
+<pre>
+ (*FAIL) or (*F)
+</pre>
+This verb causes a matching failure, forcing backtracking to occur. It is
+equivalent to (?!) but easier to read. The Perl documentation notes that it is
+probably useful only when combined with (?{}) or (??{}). Those are, of course,
+Perl features that are not present in PCRE2. The nearest equivalent is the
+callout feature, as for example in this pattern:
+<pre>
+ a+(?C)(*FAIL)
+</pre>
+A match with the string "aaaa" always fails, but the callout is taken before
+each backtrack happens (in this example, 10 times).
+</P>
+<br><b>
+Recording which path was taken
+</b><br>
+<P>
+There is one verb whose main purpose is to track how a match was arrived at,
+though it also has a secondary use in conjunction with advancing the match
+starting point (see (*SKIP) below).
+<pre>
+ (*MARK:NAME) or (*:NAME)
+</pre>
+A name is always required with this verb. There may be as many instances of
+(*MARK) as you like in a pattern, and their names do not have to be unique.
+</P>
+<P>
+When a match succeeds, the name of the last-encountered (*MARK:NAME),
+(*PRUNE:NAME), or (*THEN:NAME) on the matching path is passed back to the
+caller as described in the section entitled
+<a href="pcre2api.html#matchotherdata">"Other information about the match"</a>
+in the
+<a href="pcre2api.html"><b>pcre2api</b></a>
+documentation. Here is an example of <b>pcre2test</b> output, where the "mark"
+modifier requests the retrieval and outputting of (*MARK) data:
+<pre>
+ re> /X(*MARK:A)Y|X(*MARK:B)Z/mark
+ data> XY
+ 0: XY
+ MK: A
+ XZ
+ 0: XZ
+ MK: B
+</pre>
+The (*MARK) name is tagged with "MK:" in this output, and in this example it
+indicates which of the two alternatives matched. This is a more efficient way
+of obtaining this information than putting each alternative in its own
+capturing parentheses.
+</P>
+<P>
+If a verb with a name is encountered in a positive assertion that is true, the
+name is recorded and passed back if it is the last-encountered. This does not
+happen for negative assertions or failing positive assertions.
+</P>
+<P>
+After a partial match or a failed match, the last encountered name in the
+entire match process is returned. For example:
+<pre>
+ re> /X(*MARK:A)Y|X(*MARK:B)Z/mark
+ data> XP
+ No match, mark = B
+</pre>
+Note that in this unanchored example the mark is retained from the match
+attempt that started at the letter "X" in the subject. Subsequent match
+attempts starting at "P" and then with an empty string do not get as far as the
+(*MARK) item, but nevertheless do not reset it.
+</P>
+<P>
+If you are interested in (*MARK) values after failed matches, you should
+probably set the PCRE2_NO_START_OPTIMIZE option
+<a href="#nooptimize">(see above)</a>
+to ensure that the match is always attempted.
+</P>
+<br><b>
+Verbs that act after backtracking
+</b><br>
+<P>
+The following verbs do nothing when they are encountered. Matching continues
+with what follows, but if there is no subsequent match, causing a backtrack to
+the verb, a failure is forced. That is, backtracking cannot pass to the left of
+the verb. However, when one of these verbs appears inside an atomic group
+(which includes any group that is called as a subroutine) or in an assertion
+that is true, its effect is confined to that group, because once the group has
+been matched, there is never any backtracking into it. In this situation,
+backtracking has to jump to the left of the entire atomic group or assertion.
+</P>
+<P>
+These verbs differ in exactly what kind of failure occurs when backtracking
+reaches them. The behaviour described below is what happens when the verb is
+not in a subroutine or an assertion. Subsequent sections cover these special
+cases.
+<pre>
+ (*COMMIT)
+</pre>
+This verb, which may not be followed by a name, causes the whole match to fail
+outright if there is a later matching failure that causes backtracking to reach
+it. Even if the pattern is unanchored, no further attempts to find a match by
+advancing the starting point take place. If (*COMMIT) is the only backtracking
+verb that is encountered, once it has been passed <b>pcre2_match()</b> is
+committed to finding a match at the current starting point, or not at all. For
+example:
+<pre>
+ a+(*COMMIT)b
+</pre>
+This matches "xxaab" but not "aacaab". It can be thought of as a kind of
+dynamic anchor, or "I've started, so I must finish." The name of the most
+recently passed (*MARK) in the path is passed back when (*COMMIT) forces a
+match failure.
+</P>
+<P>
+If there is more than one backtracking verb in a pattern, a different one that
+follows (*COMMIT) may be triggered first, so merely passing (*COMMIT) during a
+match does not always guarantee that a match must be at this starting point.
+</P>
+<P>
+Note that (*COMMIT) at the start of a pattern is not the same as an anchor,
+unless PCRE2's start-of-match optimizations are turned off, as shown in this
+output from <b>pcre2test</b>:
+<pre>
+ re> /(*COMMIT)abc/
+ data> xyzabc
+ 0: abc
+ data>
+ re> /(*COMMIT)abc/no_start_optimize
+ data> xyzabc
+ No match
+</pre>
+For the first pattern, PCRE2 knows that any match must start with "a", so the
+optimization skips along the subject to "a" before applying the pattern to the
+first set of data. The match attempt then succeeds. The second pattern disables
+the optimization that skips along to the first character. The pattern is now
+applied starting at "x", and so the (*COMMIT) causes the match to fail without
+trying any other starting points.
+<pre>
+ (*PRUNE) or (*PRUNE:NAME)
+</pre>
+This verb causes the match to fail at the current starting position in the
+subject if there is a later matching failure that causes backtracking to reach
+it. If the pattern is unanchored, the normal "bumpalong" advance to the next
+starting character then happens. Backtracking can occur as usual to the left of
+(*PRUNE), before it is reached, or when matching to the right of (*PRUNE), but
+if there is no match to the right, backtracking cannot cross (*PRUNE). In
+simple cases, the use of (*PRUNE) is just an alternative to an atomic group or
+possessive quantifier, but there are some uses of (*PRUNE) that cannot be
+expressed in any other way. In an anchored pattern (*PRUNE) has the same effect
+as (*COMMIT).
+</P>
+<P>
+The behaviour of (*PRUNE:NAME) is the not the same as (*MARK:NAME)(*PRUNE).
+It is like (*MARK:NAME) in that the name is remembered for passing back to the
+caller. However, (*SKIP:NAME) searches only for names set with (*MARK),
+ignoring those set by (*PRUNE) or (*THEN).
+<pre>
+ (*SKIP)
+</pre>
+This verb, when given without a name, is like (*PRUNE), except that if the
+pattern is unanchored, the "bumpalong" advance is not to the next character,
+but to the position in the subject where (*SKIP) was encountered. (*SKIP)
+signifies that whatever text was matched leading up to it cannot be part of a
+successful match. Consider:
+<pre>
+ a+(*SKIP)b
+</pre>
+If the subject is "aaaac...", after the first match attempt fails (starting at
+the first character in the string), the starting point skips on to start the
+next attempt at "c". Note that a possessive quantifer does not have the same
+effect as this example; although it would suppress backtracking during the
+first match attempt, the second attempt would start at the second character
+instead of skipping on to "c".
+<pre>
+ (*SKIP:NAME)
+</pre>
+When (*SKIP) has an associated name, its behaviour is modified. When it is
+triggered, the previous path through the pattern is searched for the most
+recent (*MARK) that has the same name. If one is found, the "bumpalong" advance
+is to the subject position that corresponds to that (*MARK) instead of to where
+(*SKIP) was encountered. If no (*MARK) with a matching name is found, the
+(*SKIP) is ignored.
+</P>
+<P>
+Note that (*SKIP:NAME) searches only for names set by (*MARK:NAME). It ignores
+names that are set by (*PRUNE:NAME) or (*THEN:NAME).
+<pre>
+ (*THEN) or (*THEN:NAME)
+</pre>
+This verb causes a skip to the next innermost alternative when backtracking
+reaches it. That is, it cancels any further backtracking within the current
+alternative. Its name comes from the observation that it can be used for a
+pattern-based if-then-else block:
+<pre>
+ ( COND1 (*THEN) FOO | COND2 (*THEN) BAR | COND3 (*THEN) BAZ ) ...
+</pre>
+If the COND1 pattern matches, FOO is tried (and possibly further items after
+the end of the group if FOO succeeds); on failure, the matcher skips to the
+second alternative and tries COND2, without backtracking into COND1. If that
+succeeds and BAR fails, COND3 is tried. If subsequently BAZ fails, there are no
+more alternatives, so there is a backtrack to whatever came before the entire
+group. If (*THEN) is not inside an alternation, it acts like (*PRUNE).
+</P>
+<P>
+The behaviour of (*THEN:NAME) is the not the same as (*MARK:NAME)(*THEN).
+It is like (*MARK:NAME) in that the name is remembered for passing back to the
+caller. However, (*SKIP:NAME) searches only for names set with (*MARK),
+ignoring those set by (*PRUNE) and (*THEN).
+</P>
+<P>
+A subpattern that does not contain a | character is just a part of the
+enclosing alternative; it is not a nested alternation with only one
+alternative. The effect of (*THEN) extends beyond such a subpattern to the
+enclosing alternative. Consider this pattern, where A, B, etc. are complex
+pattern fragments that do not contain any | characters at this level:
+<pre>
+ A (B(*THEN)C) | D
+</pre>
+If A and B are matched, but there is a failure in C, matching does not
+backtrack into A; instead it moves to the next alternative, that is, D.
+However, if the subpattern containing (*THEN) is given an alternative, it
+behaves differently:
+<pre>
+ A (B(*THEN)C | (*FAIL)) | D
+</pre>
+The effect of (*THEN) is now confined to the inner subpattern. After a failure
+in C, matching moves to (*FAIL), which causes the whole subpattern to fail
+because there are no more alternatives to try. In this case, matching does now
+backtrack into A.
+</P>
+<P>
+Note that a conditional subpattern is not considered as having two
+alternatives, because only one is ever used. In other words, the | character in
+a conditional subpattern has a different meaning. Ignoring white space,
+consider:
+<pre>
+ ^.*? (?(?=a) a | b(*THEN)c )
+</pre>
+If the subject is "ba", this pattern does not match. Because .*? is ungreedy,
+it initially matches zero characters. The condition (?=a) then fails, the
+character "b" is matched, but "c" is not. At this point, matching does not
+backtrack to .*? as might perhaps be expected from the presence of the |
+character. The conditional subpattern is part of the single alternative that
+comprises the whole pattern, and so the match fails. (If there was a backtrack
+into .*?, allowing it to match "b", the match would succeed.)
+</P>
+<P>
+The verbs just described provide four different "strengths" of control when
+subsequent matching fails. (*THEN) is the weakest, carrying on the match at the
+next alternative. (*PRUNE) comes next, failing the match at the current
+starting position, but allowing an advance to the next character (for an
+unanchored pattern). (*SKIP) is similar, except that the advance may be more
+than one character. (*COMMIT) is the strongest, causing the entire match to
+fail.
+</P>
+<br><b>
+More than one backtracking verb
+</b><br>
+<P>
+If more than one backtracking verb is present in a pattern, the one that is
+backtracked onto first acts. For example, consider this pattern, where A, B,
+etc. are complex pattern fragments:
+<pre>
+ (A(*COMMIT)B(*THEN)C|ABD)
+</pre>
+If A matches but B fails, the backtrack to (*COMMIT) causes the entire match to
+fail. However, if A and B match, but C fails, the backtrack to (*THEN) causes
+the next alternative (ABD) to be tried. This behaviour is consistent, but is
+not always the same as Perl's. It means that if two or more backtracking verbs
+appear in succession, all the the last of them has no effect. Consider this
+example:
+<pre>
+ ...(*COMMIT)(*PRUNE)...
+</pre>
+If there is a matching failure to the right, backtracking onto (*PRUNE) causes
+it to be triggered, and its action is taken. There can never be a backtrack
+onto (*COMMIT).
+<a name="btrepeat"></a></P>
+<br><b>
+Backtracking verbs in repeated groups
+</b><br>
+<P>
+PCRE2 differs from Perl in its handling of backtracking verbs in repeated
+groups. For example, consider:
+<pre>
+ /(a(*COMMIT)b)+ac/
+</pre>
+If the subject is "abac", Perl matches, but PCRE2 fails because the (*COMMIT)
+in the second repeat of the group acts.
+<a name="btassert"></a></P>
+<br><b>
+Backtracking verbs in assertions
+</b><br>
+<P>
+(*FAIL) in an assertion has its normal effect: it forces an immediate
+backtrack.
+</P>
+<P>
+(*ACCEPT) in a positive assertion causes the assertion to succeed without any
+further processing. In a negative assertion, (*ACCEPT) causes the assertion to
+fail without any further processing.
+</P>
+<P>
+The other backtracking verbs are not treated specially if they appear in a
+positive assertion. In particular, (*THEN) skips to the next alternative in the
+innermost enclosing group that has alternations, whether or not this is within
+the assertion.
+</P>
+<P>
+Negative assertions are, however, different, in order to ensure that changing a
+positive assertion into a negative assertion changes its result. Backtracking
+into (*COMMIT), (*SKIP), or (*PRUNE) causes a negative assertion to be true,
+without considering any further alternative branches in the assertion.
+Backtracking into (*THEN) causes it to skip to the next enclosing alternative
+within the assertion (the normal behaviour), but if the assertion does not have
+such an alternative, (*THEN) behaves like (*PRUNE).
+<a name="btsub"></a></P>
+<br><b>
+Backtracking verbs in subroutines

+<P>
+These behaviours occur whether or not the subpattern is called recursively.

+<P>
+(*FAIL) in a subpattern called as a subroutine has its normal effect: it forces

+<br><a name="SEC1" href="#TOC1">PCRE2 PERFORMANCE</a><br>
+<P>
+Two aspects of performance are discussed below: memory usage and processing
+time. The way you express your pattern as a regular expression can affect both
+of them.
+</P>
+<br><a name="SEC2" href="#TOC1">COMPILED PATTERN MEMORY USAGE</a><br>
+<P>
+Patterns are compiled by PCRE2 into a reasonably efficient interpretive code,
+so that most simple patterns do not use much memory. However, there is one case
+where the memory usage of a compiled pattern can be unexpectedly large. If a
+parenthesized subpattern has a quantifier with a minimum greater than 1 and/or
+a limited maximum, the whole subpattern is repeated in the compiled code. For
+example, the pattern
+<pre>
+ (abc|def){2,4}
+</pre>
+is compiled as if it were
+<pre>
+ (abc|def)(abc|def)((abc|def)(abc|def)?)?
+</pre>
+(Technical aside: It is done this way so that backtrack points within each of
+the repetitions can be independently maintained.)
+</P>
+<P>
+For regular expressions whose quantifiers use only small numbers, this is not
+usually a problem. However, if the numbers are large, and particularly if such
+repetitions are nested, the memory usage can become an embarrassment. For
+example, the very simple pattern
+<pre>
+ ((ab){1,1000}c){1,3}
+</pre>
+uses 51K bytes when compiled using the 8-bit library. When PCRE2 is compiled
+with its default internal pointer size of two bytes, the size limit on a
+compiled pattern is 64K code units in the 8-bit and 16-bit libraries, and this
+is reached with the above pattern if the outer repetition is increased from 3
+to 4. PCRE2 can be compiled to use larger internal pointers and thus handle
+larger compiled patterns, but it is better to try to rewrite your pattern to
+use less memory if you can.
+</P>
+<P>
+One way of reducing the memory usage for such patterns is to make use of
+PCRE2's
+<a href="pcre2pattern.html#subpatternsassubroutines">"subroutine"</a>
+facility. Re-writing the above pattern as
+<pre>
+ ((ab)(?2){0,999}c)(?1){0,2}
+</pre>
+reduces the memory requirements to 18K, and indeed it remains under 20K even
+with the outer repetition increased to 100. However, this pattern is not
+exactly equivalent, because the "subroutine" calls are treated as
+<a href="pcre2pattern.html#atomicgroup">atomic groups</a>
+into which there can be no backtracking if there is a subsequent matching
+failure. Therefore, PCRE2 cannot do this kind of rewriting automatically.
+Furthermore, there is a noticeable loss of speed when executing the modified
+pattern. Nevertheless, if the atomic grouping is not a problem and the loss of
+speed is acceptable, this kind of rewriting will allow you to process patterns
+that PCRE2 cannot otherwise handle.
+</P>
+<br><a name="SEC3" href="#TOC1">STACK USAGE AT RUN TIME</a><br>
+<P>
+When <b>pcre2_match()</b> is used for matching, certain kinds of pattern can
+cause it to use large amounts of the process stack. In some environments the
+default process stack is quite small, and if it runs out the result is often
+SIGSEGV. Rewriting your pattern can often help. The
+<a href="pcre2stack.html"><b>pcre2stack</b></a>
+documentation discusses this issue in detail.
+</P>
+<br><a name="SEC4" href="#TOC1">PROCESSING TIME</a><br>
+<P>
+Certain items in regular expression patterns are processed more efficiently
+than others. It is more efficient to use a character class like [aeiou] than a
+set of single-character alternatives such as (a|e|i|o|u). In general, the
+simplest construction that provides the required behaviour is usually the most
+efficient. Jeffrey Friedl's book contains a lot of useful general discussion
+about optimizing regular expressions for efficient performance. This document
+contains a few observations about PCRE2.
+</P>
+<P>
+Using Unicode character properties (the \p, \P, and \X escapes) is slow,
+because PCRE2 has to use a multi-stage table lookup whenever it needs a
+character's property. If you can find an alternative pattern that does not use
+character properties, it will probably be faster.
+</P>
+<P>
+By default, the escape sequences \b, \d, \s, and \w, and the POSIX
+character classes such as [:alpha:] do not use Unicode properties, partly for
+backwards compatibility, and partly for performance reasons. However, you can
+set the PCRE2_UCP option or start the pattern with (*UCP) if you want Unicode
+character properties to be used. This can double the matching time for items
+such as \d, when matched with <b>pcre2_match()</b>; the performance loss is
+less with a DFA matching function, and in both cases there is not much
+difference for \b.
+</P>
+<P>
+When a pattern begins with .* not in atomic parentheses, nor in parentheses
+that are the subject of a backreference, and the PCRE2_DOTALL option is set,
+the pattern is implicitly anchored by PCRE2, since it can match only at the
+start of a subject string. If the pattern has multiple top-level branches, they
+must all be anchorable. The optimization can be disabled by the
+PCRE2_NO_DOTSTAR_ANCHOR option, and is automatically disabled if the pattern
+contains (*PRUNE) or (*SKIP).
+</P>
+<P>
+If PCRE2_DOTALL is not set, PCRE2 cannot make this optimization, because the
+dot metacharacter does not then match a newline, and if the subject string
+contains newlines, the pattern may match from the character immediately
+following one of them instead of from the very start. For example, the pattern
+<pre>
+ .*second
+</pre>
+matches the subject "first\nand second" (where \n stands for a newline
+character), with the match starting at the seventh character. In order to do
+this, PCRE2 has to retry the match starting after every newline in the subject.
+</P>
+<P>
+If you are using such a pattern with subject strings that do not contain
+newlines, the best performance is obtained by setting PCRE2_DOTALL, or starting
+the pattern with ^.* or ^.*? to indicate explicit anchoring. That saves PCRE2
+from having to scan along the subject looking for a newline to restart at.
+</P>
+<P>
+Beware of patterns that contain nested indefinite repeats. These can take a
+long time to run when applied to a string that does not match. Consider the
+pattern fragment
+<pre>
+ ^(a+)*
+</pre>
+This can match "aaaa" in 16 different ways, and this number increases very
+rapidly as the string gets longer. (The * repeat can match 0, 1, 2, 3, or 4
+times, and for each of those cases other than 0 or 4, the + repeats can match
+different numbers of times.) When the remainder of the pattern is such that the
+entire match is going to fail, PCRE2 has in principle to try every possible
+variation, and this can take an extremely long time, even for relatively short
+strings.
+</P>
+<P>
+An optimization catches some of the more simple cases such as
+<pre>
+ (a+)*b
+</pre>
+where a literal character follows. Before embarking on the standard matching
+procedure, PCRE2 checks that there is a "b" later in the subject string, and if
+there is not, it fails the match immediately. However, when there is no
+following literal this optimization cannot be used. You can see the difference
+by comparing the behaviour of
+<pre>
+ (a+)*\d
+</pre>
+with the pattern above. The former gives a failure almost instantly when
+applied to a whole line of "a" characters, whereas the latter takes an
+appreciable time with strings longer than about 20 characters.
+</P>
+<P>
+In many cases, the solution to this kind of performance issue is to use an
+atomic group or a possessive quantifier.

+<br><a name="SEC2" href="#TOC1">DESCRIPTION</a><br>
+<P>
+This set of functions provides a POSIX-style API for the PCRE2 regular
+expression 8-bit library. See the
+<a href="pcre2api.html"><b>pcre2api</b></a>
+documentation for a description of PCRE2's native API, which contains much
+additional functionality. There is no POSIX-style wrapper for PCRE2's 16-bit
+and 32-bit libraries.
+</P>
+<P>
+The functions described here are just wrapper functions that ultimately call
+the PCRE2 native API. Their prototypes are defined in the <b>pcre2posix.h</b>
+header file, and on Unix systems the library itself is called
+<b>libpcre2-posix.a</b>, so can be accessed by adding <b>-lpcre2-posix</b> to the
+command for linking an application that uses them. Because the POSIX functions
+call the native ones, it is also necessary to add <b>-lpcre2-8</b>.
+</P>
+<P>
+Those POSIX option bits that can reasonably be mapped to PCRE2 native options
+have been implemented. In addition, the option REG_EXTENDED is defined with the
+value zero. This has no effect, but since programs that are written to the
+POSIX interface often use it, this makes it easier to slot in PCRE2 as a
+replacement library. Other POSIX options are not even defined.
+</P>
+<P>
+There are also some other options that are not defined by POSIX. These have
+been added at the request of users who want to make use of certain
+PCRE2-specific features via the POSIX calling interface.
+</P>
+<P>
+When PCRE2 is called via these functions, it is only the API that is POSIX-like
+in style. The syntax and semantics of the regular expressions themselves are
+still those of Perl, subject to the setting of various PCRE2 options, as
+described below. "POSIX-like in style" means that the API approximates to the
+POSIX definition; it is not fully POSIX-compatible, and in multi-unit encoding
+domains it is probably even less compatible.
+</P>
+<P>
+The header for these functions is supplied as <b>pcre2posix.h</b> to avoid any
+potential clash with other POSIX libraries. It can, of course, be renamed or
+aliased as <b>regex.h</b>, which is the "correct" name. It provides two
+structure types, <i>regex_t</i> for compiled internal forms, and
+<i>regmatch_t</i> for returning captured substrings. It also defines some
+constants whose names start with "REG_"; these are used for setting options and
+identifying error codes.
+</P>
+<br><a name="SEC3" href="#TOC1">COMPILING A PATTERN</a><br>
+<P>
+The function <b>regcomp()</b> is called to compile a pattern into an
+internal form. The pattern is a C string terminated by a binary zero, and
+is passed in the argument <i>pattern</i>. The <i>preg</i> argument is a pointer
+to a <b>regex_t</b> structure that is used as a base for storing information
+about the compiled regular expression.
+</P>
+<P>
+The argument <i>cflags</i> is either zero, or contains one or more of the bits
+defined by the following macros:
+<pre>
+ REG_DOTALL
+</pre>
+The PCRE2_DOTALL option is set when the regular expression is passed for
+compilation to the native function. Note that REG_DOTALL is not part of the
+POSIX standard.
+<pre>
+ REG_ICASE
+</pre>
+The PCRE2_CASELESS option is set when the regular expression is passed for
+compilation to the native function.
+<pre>
+ REG_NEWLINE
+</pre>
+The PCRE2_MULTILINE option is set when the regular expression is passed for
+compilation to the native function. Note that this does <i>not</i> mimic the
+defined POSIX behaviour for REG_NEWLINE (see the following section).
+<pre>
+ REG_NOSUB
+</pre>
+The PCRE2_NO_AUTO_CAPTURE option is set when the regular expression is passed
+for compilation to the native function. In addition, when a pattern that is
+compiled with this flag is passed to <b>regexec()</b> for matching, the
+<i>nmatch</i> and <i>pmatch</i> arguments are ignored, and no captured strings
+are returned.
+<pre>
+ REG_UCP
+</pre>
+The PCRE2_UCP option is set when the regular expression is passed for
+compilation to the native function. This causes PCRE2 to use Unicode properties
+when matchine \d, \w, etc., instead of just recognizing ASCII values. Note
+that REG_UCP is not part of the POSIX standard.
+<pre>
+ REG_UNGREEDY
+</pre>
+The PCRE2_UNGREEDY option is set when the regular expression is passed for
+compilation to the native function. Note that REG_UNGREEDY is not part of the
+POSIX standard.
+<pre>
+ REG_UTF
+</pre>
+The PCRE2_UTF option is set when the regular expression is passed for
+compilation to the native function. This causes the pattern itself and all data
+strings used for matching it to be treated as UTF-8 strings. Note that REG_UTF
+is not part of the POSIX standard.
+</P>
+<P>
+In the absence of these flags, no options are passed to the native function.
+This means the the regex is compiled with PCRE2 default semantics. In
+particular, the way it handles newline characters in the subject string is the
+Perl way, not the POSIX way. Note that setting PCRE2_MULTILINE has only
+<i>some</i> of the effects specified for REG_NEWLINE. It does not affect the way
+newlines are matched by the dot metacharacter (they are not) or by a negative
+class such as [^a] (they are).
+</P>
+<P>
+The yield of <b>regcomp()</b> is zero on success, and non-zero otherwise. The
+<i>preg</i> structure is filled in on success, and one member of the structure
+is public: <i>re_nsub</i> contains the number of capturing subpatterns in
+the regular expression. Various error codes are defined in the header file.
+</P>
+<P>
+NOTE: If the yield of <b>regcomp()</b> is non-zero, you must not attempt to
+use the contents of the <i>preg</i> structure. If, for example, you pass it to
+<b>regexec()</b>, the result is undefined and your program is likely to crash.
+</P>
+<br><a name="SEC4" href="#TOC1">MATCHING NEWLINE CHARACTERS</a><br>
+<P>
+This area is not simple, because POSIX and Perl take different views of things.
+It is not possible to get PCRE2 to obey POSIX semantics, but then PCRE2 was
+never intended to be a POSIX engine. The following table lists the different
+possibilities for matching newline characters in Perl and PCRE2:
+<pre>
+ Default Change with
+
+ . matches newline no PCRE2_DOTALL
+ newline matches [^a] yes not changeable
+ $ matches \n at end yes PCRE2_DOLLAR_ENDONLY
+ $ matches \n in middle no PCRE2_MULTILINE
+ ^ matches \n in middle no PCRE2_MULTILINE
+</pre>
+This is the equivalent table for a POSIX-compatible pattern matcher:
+<pre>
+ Default Change with
+
+ . matches newline yes REG_NEWLINE
+ newline matches [^a] yes REG_NEWLINE
+ $ matches \n at end no REG_NEWLINE
+ $ matches \n in middle no REG_NEWLINE
+ ^ matches \n in middle no REG_NEWLINE
+</pre>
+This behaviour is not what happens when PCRE2 is called via its POSIX
+API. By default, PCRE2's behaviour is the same as Perl's, except that there is
+no equivalent for PCRE2_DOLLAR_ENDONLY in Perl. In both PCRE2 and Perl, there
+is no way to stop newline from matching [^a].
+</P>
+<P>
+Default POSIX newline handling can be obtained by setting PCRE2_DOTALL and
+PCRE2_DOLLAR_ENDONLY when calling <b>pcre2_compile()</b> directly, but there is
+no way to make PCRE2 behave exactly as for the REG_NEWLINE action. When using
+the POSIX API, passing REG_NEWLINE to PCRE2's <b>regcomp()</b> function
+causes PCRE2_MULTILINE to be passed to <b>pcre2_compile()</b>, and REG_DOTALL
+passes PCRE2_DOTALL. There is no way to pass PCRE2_DOLLAR_ENDONLY.
+</P>
+<br><a name="SEC5" href="#TOC1">MATCHING A PATTERN</a><br>
+<P>
+The function <b>regexec()</b> is called to match a compiled pattern <i>preg</i>
+against a given <i>string</i>, which is by default terminated by a zero byte
+(but see REG_STARTEND below), subject to the options in <i>eflags</i>. These can
+be:
+<pre>
+ REG_NOTBOL
+</pre>
+The PCRE2_NOTBOL option is set when calling the underlying PCRE2 matching
+function.
+<pre>
+ REG_NOTEMPTY
+</pre>
+The PCRE2_NOTEMPTY option is set when calling the underlying PCRE2 matching
+function. Note that REG_NOTEMPTY is not part of the POSIX standard. However,
+setting this option can give more POSIX-like behaviour in some situations.
+<pre>
+ REG_NOTEOL
+</pre>
+The PCRE2_NOTEOL option is set when calling the underlying PCRE2 matching
+function.
+<pre>
+ REG_STARTEND
+</pre>
+The string is considered to start at <i>string</i> + <i>pmatch[0].rm_so</i> and
+to have a terminating NUL located at <i>string</i> + <i>pmatch[0].rm_eo</i>
+(there need not actually be a NUL at that location), regardless of the value of
+<i>nmatch</i>. This is a BSD extension, compatible with but not specified by
+IEEE Standard 1003.2 (POSIX.2), and should be used with caution in software
+intended to be portable to other systems. Note that a non-zero <i>rm_so</i> does
+not imply REG_NOTBOL; REG_STARTEND affects only the location of the string, not
+how it is matched. Setting REG_STARTEND and passing <i>pmatch</i> as NULL are
+mutually exclusive; the error REG_INVARG is returned.
+</P>
+<P>
+If the pattern was compiled with the REG_NOSUB flag, no data about any matched
+strings is returned. The <i>nmatch</i> and <i>pmatch</i> arguments of
+<b>regexec()</b> are ignored.
+</P>
+<P>
+If the value of <i>nmatch</i> is zero, or if the value <i>pmatch</i> is NULL,
+no data about any matched strings is returned.
+</P>
+<P>
+Otherwise,the portion of the string that was matched, and also any captured
+substrings, are returned via the <i>pmatch</i> argument, which points to an
+array of <i>nmatch</i> structures of type <i>regmatch_t</i>, containing the
+members <i>rm_so</i> and <i>rm_eo</i>. These contain the byte offset to the first
+character of each substring and the offset to the first character after the end
+of each substring, respectively. The 0th element of the vector relates to the
+entire portion of <i>string</i> that was matched; subsequent elements relate to
+the capturing subpatterns of the regular expression. Unused entries in the
+array have both structure members set to -1.
+</P>
+<P>
+A successful match yields a zero return; various error codes are defined in the
+header file, of which REG_NOMATCH is the "expected" failure code.
+</P>
+<br><a name="SEC6" href="#TOC1">ERROR MESSAGES</a><br>
+<P>
+The <b>regerror()</b> function maps a non-zero errorcode from either
+<b>regcomp()</b> or <b>regexec()</b> to a printable message. If <i>preg</i> is not
+NULL, the error should have arisen from the use of that structure. A message
+terminated by a binary zero is placed in <i>errbuf</i>. If the buffer is too
+short, only the first <i>errbuf_size</i> - 1 characters of the error message are
+used. The yield of the function is the size of buffer needed to hold the whole
+message, including the terminating zero. This value is greater than
+<i>errbuf_size</i> if the message was truncated.
+</P>
+<br><a name="SEC7" href="#TOC1">MEMORY USAGE</a><br>
+<P>
+Compiling a regular expression causes memory to be allocated and associated
+with the <i>preg</i> structure. The function <b>regfree()</b> frees all such
+memory, after which <i>preg</i> may no longer be used as a compiled expression.

+<br><b>
+PCRE2 SAMPLE PROGRAM
+</b><br>
+<P>
+A simple, complete demonstration program to get you started with using PCRE2 is
+supplied in the file <i>pcre2demo.c</i> in the <b>src</b> directory in the PCRE2
+distribution. A listing of this program is given in the
+<a href="pcre2demo.html"><b>pcre2demo</b></a>
+documentation. If you do not have a copy of the PCRE2 distribution, you can
+save this listing to re-create the contents of <i>pcre2demo.c</i>.
+</P>
+<P>
+The demonstration program, which uses the PCRE2 8-bit library, compiles the
+regular expression that is its first argument, and matches it against the
+subject string in its second argument. No PCRE2 options are set, and default
+character tables are used. If matching succeeds, the program outputs the
+portion of the subject that matched, together with the contents of any captured
+substrings.
+</P>
+<P>
+If the -g option is given on the command line, the program then goes on to
+check for further matches of the same regular expression in the same subject
+string. The logic is a little bit tricky because of the possibility of matching
+an empty string. Comments in the code explain what is going on.
+</P>
+<P>
+If PCRE2 is installed in the standard include and library directories for your
+operating system, you should be able to compile the demonstration program using
+this command:
+<pre>
+ gcc -o pcre2demo pcre2demo.c -lpcre2-8
+</pre>
+If PCRE2 is installed elsewhere, you may need to add additional options to the
+command line. For example, on a Unix-like system that has PCRE2 installed in
+<i>/usr/local</i>, you can compile the demonstration program using a command
+like this:
+<pre>
+ gcc -o pcre2demo -I/usr/local/include pcre2demo.c -L/usr/local/lib -lpcre2-8
+
+</PRE>
+</P>
+<P>
+Once you have compiled and linked the demonstration program, you can run simple
+tests like this:
+<pre>
+ ./pcre2demo 'cat|dog' 'the cat sat on the mat'
+ ./pcre2demo -g 'cat|dog' 'the dog sat on the cat'
+</pre>
+Note that there is a much more comprehensive test program, called
+<a href="pcre2test.html"><b>pcre2test</b>,</a>
+which supports many more facilities for testing regular expressions using the
+PCRE2 libraries. The
+<a href="pcre2demo.html"><b>pcre2demo</b></a>
+program is provided as a simple coding example.
+</P>
+<P>
+If you try to run
+<a href="pcre2demo.html"><b>pcre2demo</b></a>
+when PCRE2 is not installed in the standard library directory, you may get an
+error like this on some operating systems (e.g. Solaris):
+<pre>
+ ld.so.1: a.out: fatal: libpcre2.so.0: open failed: No such file or directory
+</pre>
+This is caused by the way shared library support works on those systems. You
+need to add
+<pre>
+ -R/usr/local/lib
+</pre>
+(for example) to the compile command to get round this problem.

+If you are running an application that uses a large number of regular
+expression patterns, it may be useful to store them in a precompiled form
+instead of having to compile them every time the application is run. However,
+if you are using the just-in-time optimization feature, it is not possible to
+save and reload the JIT data, because it is position-dependent. The host on
+which the patterns are reloaded must be running the same version of PCRE2, with
+the same code unit width, and must also have the same endianness, pointer width
+and PCRE2_SIZE type. For example, patterns compiled on a 32-bit system using
+PCRE2's 16-bit library cannot be reloaded on a 64-bit system, nor can they be
+reloaded using the 8-bit library.
+</P>
+<br><a name="SEC2" href="#TOC1">SAVING COMPILED PATTERNS</a><br>
+<P>
+Before compiled patterns can be saved they must be serialized, that is,
+converted to a stream of bytes. A single byte stream may contain any number of
+compiled patterns, but they must all use the same character tables. A single
+copy of the tables is included in the byte stream (its size is 1088 bytes). For
+more details of character tables, see the
+<a href="pcre2api.html#localesupport">section on locale support</a>
+in the
+<a href="pcre2api.html"><b>pcre2api</b></a>
+documentation.
+</P>
+<P>
+The function <b>pcre2_serialize_encode()</b> creates a serialized byte stream
+from a list of compiled patterns. Its first two arguments specify the list,
+being a pointer to a vector of pointers to compiled patterns, and the length of
+the vector. The third and fourth arguments point to variables which are set to
+point to the created byte stream and its length, respectively. The final
+argument is a pointer to a general context, which can be used to specify custom
+memory mangagement functions. If this argument is NULL, <b>malloc()</b> is used
+to obtain memory for the byte stream. The yield of the function is the number
+of serialized patterns, or one of the following negative error codes:
+<pre>
+ PCRE2_ERROR_BADDATA the number of patterns is zero or less
+ PCRE2_ERROR_BADMAGIC mismatch of id bytes in one of the patterns
+ PCRE2_ERROR_MEMORY memory allocation failed
+ PCRE2_ERROR_MIXEDTABLES the patterns do not all use the same tables
+ PCRE2_ERROR_NULL the 1st, 3rd, or 4th argument is NULL
+</pre>
+PCRE2_ERROR_BADMAGIC means either that a pattern's code has been corrupted, or
+that a slot in the vector does not point to a compiled pattern.
+</P>
+<P>
+Once a set of patterns has been serialized you can save the data in any
+appropriate manner. Here is sample code that compiles two patterns and writes
+them to a file. It assumes that the variable <i>fd</i> refers to a file that is
+open for output. The error checking that should be present in a real
+application has been omitted for simplicity.
+<pre>
+ int errorcode;
+ uint8_t *bytes;
+ PCRE2_SIZE erroroffset;
+ PCRE2_SIZE bytescount;
+ pcre2_code *list_of_codes[2];
+ list_of_codes[0] = pcre2_compile("first pattern",
+ PCRE2_ZERO_TERMINATED, 0, &errorcode, &erroroffset, NULL);
+ list_of_codes[1] = pcre2_compile("second pattern",
+ PCRE2_ZERO_TERMINATED, 0, &errorcode, &erroroffset, NULL);
+ errorcode = pcre2_serialize_encode(list_of_codes, 2, &bytes,
+ &bytescount, NULL);
+ errorcode = fwrite(bytes, 1, bytescount, fd);
+</pre>
+Note that the serialized data is binary data that may contain any of the 256
+possible byte values. On systems that make a distinction between binary and
+non-binary data, be sure that the file is opened for binary output.
+</P>
+<P>
+Serializing a set of patterns leaves the original data untouched, so they can
+still be used for matching. Their memory must eventually be freed in the usual
+way by calling <b>pcre2_code_free()</b>. When you have finished with the byte
+stream, it too must be freed by calling <b>pcre2_serialize_free()</b>.
+</P>
+<br><a name="SEC3" href="#TOC1">RE-USING PRECOMPILED PATTERNS</a><br>
+<P>
+In order to re-use a set of saved patterns you must first make the serialized
+byte stream available in main memory (for example, by reading from a file). The
+management of this memory block is up to the application. You can use the
+<b>pcre2_serialize_get_number_of_codes()</b> function to find out how many
+compiled patterns are in the serialized data without actually decoding the
+patterns:
+<pre>
+ uint8_t *bytes = <serialized data>;
+ int32_t number_of_codes = pcre2_serialize_get_number_of_codes(bytes);
+</pre>
+The <b>pcre2_serialize_decode()</b> function reads a byte stream and recreates
+the compiled patterns in new memory blocks, setting pointers to them in a
+vector. The first two arguments are a pointer to a suitable vector and its
+length, and the third argument points to a byte stream. The final argument is a
+pointer to a general context, which can be used to specify custom memory
+mangagement functions for the decoded patterns. If this argument is NULL,
+<b>malloc()</b> and <b>free()</b> are used. After deserialization, the byte
+stream is no longer needed and can be discarded.
+<pre>
+ int32_t number_of_codes;
+ pcre2_code *list_of_codes[2];
+ uint8_t *bytes = <serialized data>;
+ int32_t number_of_codes =
+ pcre2_serialize_decode(list_of_codes, 2, bytes, NULL);
+</pre>
+If the vector is not large enough for all the patterns in the byte stream, it
+is filled with those that fit, and the remainder are ignored. The yield of the
+function is the number of decoded patterns, or one of the following negative
+error codes:
+<pre>
+ PCRE2_ERROR_BADDATA second argument is zero or less
+ PCRE2_ERROR_BADMAGIC mismatch of id bytes in the data
+ PCRE2_ERROR_BADMODE mismatch of variable unit size or PCRE2 version
+ PCRE2_ERROR_MEMORY memory allocation failed
+ PCRE2_ERROR_NULL first or third argument is NULL
+</pre>
+PCRE2_ERROR_BADMAGIC may mean that the data is corrupt, or that it was compiled
+on a system with different endianness.
+</P>
+<P>
+Decoded patterns can be used for matching in the usual way, and must be freed
+by calling <b>pcre2_code_free()</b>. However, be aware that there is a potential
+race issue if you are using multiple patterns that were decoded from a single
+byte stream in a multithreaded application. A single copy of the character
+tables is used by all the decoded patterns and a reference count is used to
+arrange for its memory to be automatically freed when the last pattern is
+freed, but there is no locking on this reference count. Therefore, if you want
+to call <b>pcre2_code_free()</b> for these patterns in different threads, you
+must arrange your own locking, and ensure that <b>pcre2_code_free()</b> cannot
+be called by two threads at the same time.
+</P>
+<P>
+If a pattern was processed by <b>pcre2_jit_compile()</b> before being
+serialized, the JIT data is discarded and so is no longer available after a
+save/restore cycle. You can, however, process a restored pattern with
+<b>pcre2_jit_compile()</b> if you wish.

+<br><b>
+PCRE2 DISCUSSION OF STACK USAGE
+</b><br>
+<P>
+When you call <b>pcre2_match()</b>, it makes use of an internal function called
+<b>match()</b>. This calls itself recursively at branch points in the pattern,
+in order to remember the state of the match so that it can back up and try a
+different alternative after a failure. As matching proceeds deeper and deeper
+into the tree of possibilities, the recursion depth increases. The
+<b>match()</b> function is also called in other circumstances, for example,
+whenever a parenthesized sub-pattern is entered, and in certain cases of
+repetition.
+</P>
+<P>
+Not all calls of <b>match()</b> increase the recursion depth; for an item such
+as a* it may be called several times at the same level, after matching
+different numbers of a's. Furthermore, in a number of cases where the result of
+the recursive call would immediately be passed back as the result of the
+current call (a "tail recursion"), the function is just restarted instead.
+</P>
+<P>
+Each time the internal <b>match()</b> function is called recursively, it uses
+memory from the process stack. For certain kinds of pattern and data, very
+large amounts of stack may be needed, despite the recognition of "tail
+recursion". Note that if PCRE2 is compiled with the -fsanitize=address option
+of the GCC compiler, the stack requirements are greatly increased.
+</P>
+<P>
+The above comments apply when <b>pcre2_match()</b> is run in its normal
+interpretive manner. If the compiled pattern was processed by
+<b>pcre2_jit_compile()</b>, and just-in-time compiling was successful, and the
+options passed to <b>pcre2_match()</b> were not incompatible, the matching
+process uses the JIT-compiled code instead of the <b>match()</b> function. In
+this case, the memory requirements are handled entirely differently. See the
+<a href="pcre2jit.html"><b>pcre2jit</b></a>
+documentation for details.
+</P>
+<P>
+The <b>pcre2_dfa_match()</b> function operates in a different way to
+<b>pcre2_match()</b>, and uses recursion only when there is a regular expression
+recursion or subroutine call in the pattern. This includes the processing of
+assertion and "once-only" subpatterns, which are handled like subroutine calls.
+Normally, these are never very deep, and the limit on the complexity of
+<b>pcre2_dfa_match()</b> is controlled by the amount of workspace it is given.
+However, it is possible to write patterns with runaway infinite recursions;
+such patterns will cause <b>pcre2_dfa_match()</b> to run out of stack. At
+present, there is no protection against this.
+</P>
+<P>
+The comments that follow do NOT apply to <b>pcre2_dfa_match()</b>; they are
+relevant only for <b>pcre2_match()</b> without the JIT optimization.
+</P>
+<br><b>
+Reducing <b>pcre2_match()</b>'s stack usage
+</b><br>
+<P>
+You can often reduce the amount of recursion, and therefore the
+amount of stack used, by modifying the pattern that is being matched. Consider,
+for example, this pattern:
+<pre>
+ ([^<]|<(?!inet))+
+</pre>
+It matches from wherever it starts until it encounters "<inet" or the end of
+the data, and is the kind of pattern that might be used when processing an XML
+file. Each iteration of the outer parentheses matches either one character that
+is not "<" or a "<" that is not followed by "inet". However, each time a
+parenthesis is processed, a recursion occurs, so this formulation uses a stack
+frame for each matched character. For a long string, a lot of stack is
+required. Consider now this rewritten pattern, which matches exactly the same
+strings:
+<pre>
+ ([^<]++|<(?!inet))+
+</pre>
+This uses very much less stack, because runs of characters that do not contain
+"<" are "swallowed" in one item inside the parentheses. Recursion happens only
+when a "<" character that is not followed by "inet" is encountered (and we
+assume this is relatively rare). A possessive quantifier is used to stop any
+backtracking into the runs of non-"<" characters, but that is not related to
+stack usage.
+</P>
+<P>
+This example shows that one way of avoiding stack problems when matching long
+subject strings is to write repeated parenthesized subpatterns to match more
+than one character whenever possible.
+</P>
+<br><b>
+Compiling PCRE2 to use heap instead of stack for <b>pcre2_match()</b>
+</b><br>
+<P>
+In environments where stack memory is constrained, you might want to compile
+PCRE2 to use heap memory instead of stack for remembering back-up points when
+<b>pcre2_match()</b> is running. This makes it run more slowly, however. Details
+of how to do this are given in the
+<a href="pcre2build.html"><b>pcre2build</b></a>
+documentation. When built in this way, instead of using the stack, PCRE2
+gets memory for remembering backup points from the heap. By default, the memory
+is obtained by calling the system <b>malloc()</b> function, but you can arrange
+to supply your own memory management function. For details, see the section
+entitled
+<a href="pcre2api.html#matchcontext">"The match context"</a>
+in the
+<a href="pcre2api.html"><b>pcre2api</b></a>
+documentation. Since the block sizes are always the same, it may be possible to
+implement customized a memory handler that is more efficient than the standard
+function. The memory blocks obtained for this purpose are retained and re-used
+if possible while <b>pcre2_match()</b> is running. They are all freed just
+before it exits.
+</P>
+<br><b>
+Limiting <b>pcre2_match()</b>'s stack usage
+</b><br>
+<P>
+You can set limits on the number of times the internal <b>match()</b> function
+is called, both in total and recursively. If a limit is exceeded,
+<b>pcre2_match()</b> returns an error code. Setting suitable limits should
+prevent it from running out of stack. The default values of the limits are very
+large, and unlikely ever to operate. They can be changed when PCRE2 is built,
+and they can also be set when <b>pcre2_match()</b> is called. For details of
+these interfaces, see the
+<a href="pcre2build.html"><b>pcre2build</b></a>
+documentation and the section entitled
+<a href="pcre2api.html#matchcontext">"The match context"</a>
+in the
+<a href="pcre2api.html"><b>pcre2api</b></a>
+documentation.
+</P>
+<P>
+As a very rough rule of thumb, you should reckon on about 500 bytes per
+recursion. Thus, if you want to limit your stack usage to 8Mb, you should set
+the limit at 16000 recursions. A 64Mb stack, on the other hand, can support
+around 128000 recursions.
+</P>
+<P>
+The <b>pcre2test</b> test program has a modifier called "find_limits" which, if
+applied to a subject line, causes it to find the smallest limits that allow a a
+pattern to match. This is done by calling <b>pcre2_match()</b> repeatedly with
+different limits.
+</P>
+<br><b>
+Changing stack size in Unix-like systems
+</b><br>
+<P>
+In Unix-like environments, there is not often a problem with the stack unless
+very long strings are involved, though the default limit on stack size varies
+from system to system. Values from 8Mb to 64Mb are common. You can find your
+default limit by running the command:
+<pre>
+ ulimit -s
+</pre>
+Unfortunately, the effect of running out of stack is often SIGSEGV, though
+sometimes a more explicit error message is given. You can normally increase the
+limit on stack size by code such as this:
+<pre>
+ struct rlimit rlim;
+ getrlimit(RLIMIT_STACK, &rlim);
+ rlim.rlim_cur = 100*1024*1024;
+ setrlimit(RLIMIT_STACK, &rlim);
+</pre>
+This reads the current limits (soft and hard) using <b>getrlimit()</b>, then
+attempts to increase the soft limit to 100Mb using <b>setrlimit()</b>. You must
+do this before calling <b>pcre2_match()</b>.
+</P>
+<br><b>
+Changing stack size in Mac OS X
+</b><br>
+<P>
+Using <b>setrlimit()</b>, as described above, should also work on Mac OS X. It
+is also possible to set a stack size when linking a program. There is a
+discussion about stack sizes in Mac OS X at this web site:

+<P>
+<b>pcre2test [options] [input file [output file]]</b>
+<br>
+<br>
+<b>pcre2test</b> is a test program for the PCRE2 regular expression libraries,
+but it can also be used for experimenting with regular expressions. This
+document describes the features of the test program; for details of the regular
+expressions themselves, see the
+<a href="pcre2pattern.html"><b>pcre2pattern</b></a>
+documentation. For details of the PCRE2 library function calls and their
+options, see the
+<a href="pcre2api.html"><b>pcre2api</b></a>
+documentation.
+</P>
+<P>
+The input for <b>pcre2test</b> is a sequence of regular expression patterns and
+subject strings to be matched. There are also command lines for setting
+defaults and controlling some special actions. The output shows the result of
+each match attempt. Modifiers on external or internal command lines, the
+patterns, and the subject lines specify PCRE2 function options, control how the
+subject is processed, and what output is produced.
+</P>
+<P>
+As the original fairly simple PCRE library evolved, it acquired many different
+features, and as a result, the original <b>pcretest</b> program ended up with a
+lot of options in a messy, arcane syntax, for testing all the features. The
+move to the new PCRE2 API provided an opportunity to re-implement the test
+program as <b>pcre2test</b>, with a cleaner modifier syntax. Nevertheless, there
+are still many obscure modifiers, some of which are specifically designed for
+use in conjunction with the test script and data files that are distributed as
+part of PCRE2. All the modifiers are documented here, some without much
+justification, but many of them are unlikely to be of use except when testing
+the libraries.
+</P>
+<br><a name="SEC2" href="#TOC1">PCRE2's 8-BIT, 16-BIT AND 32-BIT LIBRARIES</a><br>
+<P>
+Different versions of the PCRE2 library can be built to support character
+strings that are encoded in 8-bit, 16-bit, or 32-bit code units. One, two, or
+all three of these libraries may be simultaneously installed. The
+<b>pcre2test</b> program can be used to test all the libraries. However, its own
+input and output are always in 8-bit format. When testing the 16-bit or 32-bit
+libraries, patterns and subject strings are converted to 16- or 32-bit format
+before being passed to the library functions. Results are converted back to
+8-bit code units for output.
+</P>
+<P>
+In the rest of this document, the names of library functions and structures
+are given in generic form, for example, <b>pcre_compile()</b>. The actual
+names used in the libraries have a suffix _8, _16, or _32, as appropriate.
+</P>
+<br><a name="SEC3" href="#TOC1">INPUT ENCODING</a><br>
+<P>
+Input to <b>pcre2test</b> is processed line by line, either by calling the C
+library's <b>fgets()</b> function, or via the <b>libreadline</b> library (see
+below). The input is processed using using C's string functions, so must not
+contain binary zeroes, even though in Unix-like environments, <b>fgets()</b>
+treats any bytes other than newline as data characters. In some Windows
+environments character 26 (hex 1A) causes an immediate end of file, and no
+further data is read.
+</P>
+<P>
+For maximum portability, therefore, it is safest to avoid non-printing
+characters in <b>pcre2test</b> input files. There is a facility for specifying a
+pattern's characters as hexadecimal pairs, thus making it possible to include
+binary zeroes in a pattern for testing purposes. Subject lines are processed
+for backslash escapes, which makes it possible to include any data value.
+</P>
+<br><a name="SEC4" href="#TOC1">COMMAND LINE OPTIONS</a><br>
+<P>
+<b>-8</b>
+If the 8-bit library has been built, this option causes it to be used (this is
+the default). If the 8-bit library has not been built, this option causes an
+error.
+</P>
+<P>
+<b>-16</b>
+If the 16-bit library has been built, this option causes it to be used. If only
+the 16-bit library has been built, this is the default. If the 16-bit library
+has not been built, this option causes an error.
+</P>
+<P>
+<b>-32</b>
+If the 32-bit library has been built, this option causes it to be used. If only
+the 32-bit library has been built, this is the default. If the 32-bit library
+has not been built, this option causes an error.
+</P>
+<P>
+<b>-b</b>
+Behave as if each pattern has the <b>/fullbincode</b> modifier; the full
+internal binary form of the pattern is output after compilation.
+</P>
+<P>
+<b>-C</b>
+Output the version number of the PCRE2 library, and all available information
+about the optional features that are included, and then exit with zero exit
+code. All other options are ignored.
+</P>
+<P>
+<b>-C</b> <i>option</i>
+Output information about a specific build-time option, then exit. This
+functionality is intended for use in scripts such as <b>RunTest</b>. The
+following options output the value and set the exit code as indicated:
+<pre>
+ ebcdic-nl the code for LF (= NL) in an EBCDIC environment:
+ 0x15 or 0x25
+ 0 if used in an ASCII environment
+ exit code is always 0
+ linksize the configured internal link size (2, 3, or 4)
+ exit code is set to the link size
+ newline the default newline setting:
+ CR, LF, CRLF, ANYCRLF, or ANY
+ exit code is always 0
+ bsr the default setting for what \R matches:
+ ANYCRLF or ANY
+ exit code is always 0
+</pre>
+The following options output 1 for true or 0 for false, and set the exit code
+to the same value:
+<pre>
+ backslash-C \C is supported (not locked out)
+ ebcdic compiled for an EBCDIC environment
+ jit just-in-time support is available
+ pcre2-16 the 16-bit library was built
+ pcre2-32 the 32-bit library was built
+ pcre2-8 the 8-bit library was built
+ unicode Unicode support is available
+</pre>
+If an unknown option is given, an error message is output; the exit code is 0.
+</P>
+<P>
+<b>-d</b>
+Behave as if each pattern has the <b>debug</b> modifier; the internal
+form and information about the compiled pattern is output after compilation;
+<b>-d</b> is equivalent to <b>-b -i</b>.
+</P>
+<P>
+<b>-dfa</b>
+Behave as if each subject line has the <b>dfa</b> modifier; matching is done
+using the <b>pcre2_dfa_match()</b> function instead of the default
+<b>pcre2_match()</b>.
+</P>
+<P>
+<b>-help</b>
+Output a brief summary these options and then exit.
+</P>
+<P>
+<b>-i</b>
+Behave as if each pattern has the <b>/info</b> modifier; information about the
+compiled pattern is given after compilation.
+</P>
+<P>
+<b>-jit</b>
+Behave as if each pattern line has the <b>jit</b> modifier; after successful
+compilation, each pattern is passed to the just-in-time compiler, if available.
+</P>
+<P>
+\fB-pattern\fB <i>modifier-list</i>
+Behave as if each pattern line contains the given modifiers.
+</P>
+<P>
+<b>-q</b>
+Do not output the version number of <b>pcre2test</b> at the start of execution.
+</P>
+<P>
+<b>-S</b> <i>size</i>
+On Unix-like systems, set the size of the run-time stack to <i>size</i>
+megabytes.
+</P>
+<P>
+<b>-subject</b> <i>modifier-list</i>
+Behave as if each subject line contains the given modifiers.
+</P>
+<P>
+<b>-t</b>
+Run each compile and match many times with a timer, and output the resulting
+times per compile or match. When JIT is used, separate times are given for the
+initial compile and the JIT compile. You can control the number of iterations
+that are used for timing by following <b>-t</b> with a number (as a separate
+item on the command line). For example, "-t 1000" iterates 1000 times. The
+default is to iterate 500,000 times.
+</P>
+<P>
+<b>-tm</b>
+This is like <b>-t</b> except that it times only the matching phase, not the
+compile phase.
+</P>
+<P>
+<b>-T</b> <b>-TM</b>
+These behave like <b>-t</b> and <b>-tm</b>, but in addition, at the end of a run,
+the total times for all compiles and matches are output.
+</P>
+<P>
+<b>-version</b>
+Output the PCRE2 version number and then exit.
+</P>
+<br><a name="SEC5" href="#TOC1">DESCRIPTION</a><br>
+<P>
+If <b>pcre2test</b> is given two filename arguments, it reads from the first and
+writes to the second. If the first name is "-", input is taken from the
+standard input. If <b>pcre2test</b> is given only one argument, it reads from
+that file and writes to stdout. Otherwise, it reads from stdin and writes to
+stdout.
+</P>
+<P>
+When <b>pcre2test</b> is built, a configuration option can specify that it
+should be linked with the <b>libreadline</b> or <b>libedit</b> library. When this
+is done, if the input is from a terminal, it is read using the <b>readline()</b>
+function. This provides line-editing and history facilities. The output from
+the <b>-help</b> option states whether or not <b>readline()</b> will be used.
+</P>
+<P>
+The program handles any number of tests, each of which consists of a set of
+input lines. Each set starts with a regular expression pattern, followed by any
+number of subject lines to be matched against that pattern. In between sets of
+test data, command lines that begin with # may appear. This file format, with
+some restrictions, can also be processed by the <b>perltest.sh</b> script that
+is distributed with PCRE2 as a means of checking that the behaviour of PCRE2
+and Perl is the same.
+</P>
+<P>
+When the input is a terminal, <b>pcre2test</b> prompts for each line of input,
+using "re>" to prompt for regular expression patterns, and "data>" to prompt
+for subject lines. Command lines starting with # can be entered only in
+response to the "re>" prompt.
+</P>
+<P>
+Each subject line is matched separately and independently. If you want to do
+multi-line matches, you have to use the \n escape sequence (or \r or \r\n,
+etc., depending on the newline setting) in a single line of input to encode the
+newline sequences. There is no limit on the length of subject lines; the input
+buffer is automatically extended if it is too small. There are replication
+features that makes it possible to generate long repetitive pattern or subject
+lines without having to supply them explicitly.
+</P>
+<P>
+An empty line or the end of the file signals the end of the subject lines for a
+test, at which point a new pattern or command line is expected if there is
+still input to be read.
+</P>
+<br><a name="SEC6" href="#TOC1">COMMAND LINES</a><br>
+<P>
+In between sets of test data, a line that begins with # is interpreted as a
+command line. If the first character is followed by white space or an
+exclamation mark, the line is treated as a comment, and ignored. Otherwise, the
+following commands are recognized:
+<pre>
+ #forbid_utf
+</pre>
+Subsequent patterns automatically have the PCRE2_NEVER_UTF and PCRE2_NEVER_UCP
+options set, which locks out the use of the PCRE2_UTF and PCRE2_UCP options and
+the use of (*UTF) and (*UCP) at the start of patterns. This command also forces
+an error if a subsequent pattern contains any occurrences of \P, \p, or \X,
+which are still supported when PCRE2_UTF is not set, but which require Unicode
+property support to be included in the library.
+</P>
+<P>
+This is a trigger guard that is used in test files to ensure that UTF or
+Unicode property tests are not accidentally added to files that are used when
+Unicode support is not included in the library. Setting PCRE2_NEVER_UTF and
+PCRE2_NEVER_UCP as a default can also be obtained by the use of <b>#pattern</b>;
+the difference is that <b>#forbid_utf</b> cannot be unset, and the automatic
+options are not displayed in pattern information, to avoid cluttering up test
+output.
+<pre>
+ #load <filename>
+</pre>
+This command is used to load a set of precompiled patterns from a file, as
+described in the section entitled "Saving and restoring compiled patterns"
+<a href="#saverestore">below.</a>
+<pre>
+ #newline_default [<newline-list>]
+</pre>
+When PCRE2 is built, a default newline convention can be specified. This
+determines which characters and/or character pairs are recognized as indicating
+a newline in a pattern or subject string. The default can be overridden when a
+pattern is compiled. The standard test files contain tests of various newline
+conventions, but the majority of the tests expect a single linefeed to be
+recognized as a newline by default. Without special action the tests would fail
+when PCRE2 is compiled with either CR or CRLF as the default newline.
+</P>
+<P>
+The #newline_default command specifies a list of newline types that are
+acceptable as the default. The types must be one of CR, LF, CRLF, ANYCRLF, or
+ANY (in upper or lower case), for example:
+<pre>
+ #newline_default LF Any anyCRLF
+</pre>
+If the default newline is in the list, this command has no effect. Otherwise,
+except when testing the POSIX API, a <b>newline</b> modifier that specifies the
+first newline convention in the list (LF in the above example) is added to any
+pattern that does not already have a <b>newline</b> modifier. If the newline
+list is empty, the feature is turned off. This command is present in a number
+of the standard test input files.
+</P>
+<P>
+When the POSIX API is being tested there is no way to override the default
+newline convention, though it is possible to set the newline convention from
+within the pattern. A warning is given if the <b>posix</b> modifier is used when
+<b>#newline_default</b> would set a default for the non-POSIX API.
+<pre>
+ #pattern <modifier-list>
+</pre>
+This command sets a default modifier list that applies to all subsequent
+patterns. Modifiers on a pattern can change these settings.
+<pre>
+ #perltest
+</pre>
+The appearance of this line causes all subsequent modifier settings to be
+checked for compatibility with the <b>perltest.sh</b> script, which is used to
+confirm that Perl gives the same results as PCRE2. Also, apart from comment
+lines, none of the other command lines are permitted, because they and many
+of the modifiers are specific to <b>pcre2test</b>, and should not be used in
+test files that are also processed by <b>perltest.sh</b>. The <b>#perltest</b>
+command helps detect tests that are accidentally put in the wrong file.
+<pre>
+ #pop [<modifiers>]

+<pre>
+ #subject <modifier-list>
+</pre>
+This command sets a default modifier list that applies to all subsequent
+subject lines. Modifiers on a subject line can change these settings.
+</P>
+<br><a name="SEC7" href="#TOC1">MODIFIER SYNTAX</a><br>
+<P>
+Modifier lists are used with both pattern and subject lines. Items in a list
+are separated by commas followed by optional white space. Trailing whitespace
+in a modifier list is ignored. Some modifiers may be given for both patterns
+and subject lines, whereas others are valid only for one or the other. Each
+modifier has a long name, for example "anchored", and some of them must be
+followed by an equals sign and a value, for example, "offset=12". Values cannot
+contain comma characters, but may contain spaces. Modifiers that do not take
+values may be preceded by a minus sign to turn off a previous setting.
+</P>
+<P>
+A few of the more common modifiers can also be specified as single letters, for
+example "i" for "caseless". In documentation, following the Perl convention,
+these are written with a slash ("the /i modifier") for clarity. Abbreviated
+modifiers must all be concatenated in the first item of a modifier list. If the
+first item is not recognized as a long modifier name, it is interpreted as a
+sequence of these abbreviations. For example:
+<pre>
+ /abc/ig,newline=cr,jit=3
+</pre>
+This is a pattern line whose modifier list starts with two one-letter modifiers
+(/i and /g). The lower-case abbreviated modifiers are the same as used in Perl.
+</P>
+<br><a name="SEC8" href="#TOC1">PATTERN SYNTAX</a><br>
+<P>
+A pattern line must start with one of the following characters (common symbols,
+excluding pattern meta-characters):
+<pre>
+ / ! " ' ` - = _ : ; , % & @ ~
+</pre>
+This is interpreted as the pattern's delimiter. A regular expression may be
+continued over several input lines, in which case the newline characters are
+included within it. It is possible to include the delimiter within the pattern
+by escaping it with a backslash, for example
+<pre>
+ /abc\/def/
+</pre>
+If you do this, the escape and the delimiter form part of the pattern, but
+since the delimiters are all non-alphanumeric, this does not affect its
+interpretation. If the terminating delimiter is immediately followed by a
+backslash, for example,
+<pre>
+ /abc/\
+</pre>
+then a backslash is added to the end of the pattern. This is done to provide a
+way of testing the error condition that arises if a pattern finishes with a
+backslash, because
+<pre>
+ /abc\/
+</pre>
+is interpreted as the first line of a pattern that starts with "abc/", causing
+pcre2test to read the next line as a continuation of the regular expression.
+</P>
+<P>
+A pattern can be followed by a modifier list (details below).
+</P>
+<br><a name="SEC9" href="#TOC1">SUBJECT LINE SYNTAX</a><br>
+<P>
+Before each subject line is passed to <b>pcre2_match()</b> or
+<b>pcre2_dfa_match()</b>, leading and trailing white space is removed, and the
+line is scanned for backslash escapes. The following provide a means of
+encoding non-printing characters in a visible way:
+<pre>
+ \a alarm (BEL, \x07)
+ \b backspace (\x08)
+ \e escape (\x27)
+ \f form feed (\x0c)
+ \n newline (\x0a)
+ \r carriage return (\x0d)
+ \t tab (\x09)
+ \v vertical tab (\x0b)
+ \nnn octal character (up to 3 octal digits); always
+ a byte unless > 255 in UTF-8 or 16-bit or 32-bit mode
+ \o{dd...} octal character (any number of octal digits}
+ \xhh hexadecimal byte (up to 2 hex digits)
+ \x{hh...} hexadecimal character (any number of hex digits)
+</pre>
+The use of \x{hh...} is not dependent on the use of the <b>utf</b> modifier on
+the pattern. It is recognized always. There may be any number of hexadecimal
+digits inside the braces; invalid values provoke error messages.
+</P>
+<P>
+Note that \xhh specifies one byte rather than one character in UTF-8 mode;
+this makes it possible to construct invalid UTF-8 sequences for testing
+purposes. On the other hand, \x{hh} is interpreted as a UTF-8 character in
+UTF-8 mode, generating more than one byte if the value is greater than 127.
+When testing the 8-bit library not in UTF-8 mode, \x{hh} generates one byte
+for values less than 256, and causes an error for greater values.
+</P>
+<P>
+In UTF-16 mode, all 4-digit \x{hhhh} values are accepted. This makes it
+possible to construct invalid UTF-16 sequences for testing purposes.
+</P>
+<P>
+In UTF-32 mode, all 4- to 8-digit \x{...} values are accepted. This makes it
+possible to construct invalid UTF-32 sequences for testing purposes.
+</P>
+<P>
+There is a special backslash sequence that specifies replication of one or more
+characters:
+<pre>
+ \[<characters>]{<count>}
+</pre>
+This makes it possible to test long strings without having to provide them as
+part of the file. For example:
+<pre>
+ \[abc]{4}
+</pre>
+is converted to "abcabcabcabc". This feature does not support nesting. To
+include a closing square bracket in the characters, code it as \x5D.
+</P>
+<P>
+A backslash followed by an equals sign marks the end of the subject string and
+the start of a modifier list. For example:
+<pre>
+ abc\=notbol,notempty
+</pre>
+If the subject string is empty and \= is followed by whitespace, the line is
+treated as a comment line, and is not used for matching. For example:
+<pre>
+ \= This is a comment.
+ abc\= This is an invalid modifier list.
+</pre>
+A backslash followed by any other non-alphanumeric character just escapes that
+character. A backslash followed by anything else causes an error. However, if
+the very last character in the line is a backslash (and there is no modifier
+list), it is ignored. This gives a way of passing an empty line as data, since
+a real empty line terminates the data input.
+</P>
+<br><a name="SEC10" href="#TOC1">PATTERN MODIFIERS</a><br>
+<P>
+There are several types of modifier that can appear in pattern lines. Except

+ tables=[0|1|2] select internal tables
+</pre>
+The effects of these modifiers are described in the following sections.
+</P>
+<br><b>
+Newline and \R handling
+</b><br>
+<P>
+The <b>bsr</b> modifier specifies what \R in a pattern should match. If it is
+set to "anycrlf", \R matches CR, LF, or CRLF only. If it is set to "unicode",
+\R matches any Unicode newline sequence. The default is specified when PCRE2
+is built, with the default default being Unicode.
+</P>
+<P>
+The <b>newline</b> modifier specifies which characters are to be interpreted as
+newlines, both in the pattern and in subject lines. The type must be one of CR,
+LF, CRLF, ANYCRLF, or ANY (in upper or lower case).
+</P>
+<br><b>
+Information about a pattern
+</b><br>
+<P>
+The <b>debug</b> modifier is a shorthand for <b>info,fullbincode</b>, requesting
+all available information.
+</P>
+<P>
+The <b>bincode</b> modifier causes a representation of the compiled code to be
+output after compilation. This information does not contain length and offset
+values, which ensures that the same output is generated for different internal
+link sizes and different code unit widths. By using <b>bincode</b>, the same
+regression tests can be used in different environments.
+</P>
+<P>
+The <b>fullbincode</b> modifier, by contrast, <i>does</i> include length and
+offset values. This is used in a few special tests that run only for specific
+code unit widths and link sizes, and is also useful for one-off tests.
+</P>
+<P>
+The <b>info</b> modifier requests information about the compiled pattern
+(whether it is anchored, has a fixed first character, and so on). The
+information is obtained from the <b>pcre2_pattern_info()</b> function. Here are
+some typical examples:
+<pre>
+ re> /(?i)(^a|^b)/m,info
+ Capturing subpattern count = 1
+ Compile options: multiline
+ Overall options: caseless multiline
+ First code unit at start or follows newline
+ Subject length lower bound = 1
+
+ re> /(?i)abc/info
+ Capturing subpattern count = 0
+ Compile options: <none>
+ Overall options: caseless
+ First code unit = 'a' (caseless)
+ Last code unit = 'c' (caseless)
+ Subject length lower bound = 3
+</pre>
+"Compile options" are those specified by modifiers; "overall options" have
+added options that are taken or deduced from the pattern. If both sets of
+options are the same, just a single "options" line is output; if there are no
+options, the line is omitted. "First code unit" is where any match must start;
+if there is more than one they are listed as "starting code units". "Last code
+unit" is the last literal code unit that must be present in any match. This is
+not necessarily the last character. These lines are omitted if no starting or
+ending code units are recorded.
+</P>
+<P>
+The <b>callout_info</b> modifier requests information about all the callouts in
+the pattern. A list of them is output at the end of any other information that
+is requested. For each callout, either its number or string is given, followed
+by the item that follows it in the pattern.
+</P>
+<br><b>
+Passing a NULL context
+</b><br>
+<P>
+Normally, <b>pcre2test</b> passes a context block to <b>pcre2_compile()</b>. If
+the <b>null_context</b> modifier is set, however, NULL is passed. This is for
+testing that <b>pcre2_compile()</b> behaves correctly in this case (it uses
+default values).
+</P>
+<br><b>
+Specifying a pattern in hex
+</b><br>
+<P>
+The <b>hex</b> modifier specifies that the characters of the pattern are to be
+interpreted as pairs of hexadecimal digits. White space is permitted between
+pairs. For example:
+<pre>
+ /ab 32 59/hex
+</pre>
+This feature is provided as a way of creating patterns that contain binary zero
+and other non-printing characters. By default, <b>pcre2test</b> passes patterns
+as zero-terminated strings to <b>pcre2_compile()</b>, giving the length as
+PCRE2_ZERO_TERMINATED. However, for patterns specified in hexadecimal, the
+actual length of the pattern is passed.
+</P>
+<br><b>
+Generating long repetitive patterns
+</b><br>
+<P>
+Some tests use long patterns that are very repetitive. Instead of creating a
+very long input line for such a pattern, you can use a special repetition
+feature, similar to the one described for subject lines above. If the
+<b>expand</b> modifier is present on a pattern, parts of the pattern that have
+the form
+<pre>
+ \[<characters>]{<count>}
+</pre>
+are expanded before the pattern is passed to <b>pcre2_compile()</b>. For
+example, \[AB]{6000} is expanded to "ABAB..." 6000 times. This construction
+cannot be nested. An initial "\[" sequence is recognized only if "]{" followed
+by decimal digits and "}" is found later in the pattern. If not, the characters
+remain in the pattern unaltered.
+</P>
+<P>
+If part of an expanded pattern looks like an expansion, but is really part of
+the actual pattern, unwanted expansion can be avoided by giving two values in
+the quantifier. For example, \[AB]{6000,6000} is not recognized as an
+expansion item.
+</P>
+<P>
+If the <b>info</b> modifier is set on an expanded pattern, the result of the
+expansion is included in the information that is output.
+</P>
+<br><b>
+JIT compilation
+</b><br>
+<P>
+Just-in-time (JIT) compiling is a heavyweight optimization that can greatly
+speed up pattern matching. See the
+<a href="pcre2jit.html"><b>pcre2jit</b></a>
+documentation for details. JIT compiling happens, optionally, after a pattern
+has been successfully compiled into an internal form. The JIT compiler converts
+this to optimized machine code. It needs to know whether the match-time options
+PCRE2_PARTIAL_HARD and PCRE2_PARTIAL_SOFT are going to be used, because
+different code is generated for the different cases. See the <b>partial</b>
+modifier in "Subject Modifiers"
+<a href="#subjectmodifiers">below</a>
+for details of how these options are specified for each match attempt.
+</P>
+<P>
+JIT compilation is requested by the <b>/jit</b> pattern modifier, which may
+optionally be followed by an equals sign and a number in the range 0 to 7.
+The three bits that make up the number specify which of the three JIT operating
+modes are to be compiled:
+<pre>
+ 1 compile JIT code for non-partial matching
+ 2 compile JIT code for soft partial matching
+ 4 compile JIT code for hard partial matching
+</pre>
+The possible values for the <b>/jit</b> modifier are therefore:
+<pre>
+ 0 disable JIT
+ 1 normal matching only
+ 2 soft partial matching only
+ 3 normal and soft partial matching
+ 4 hard partial matching only
+ 6 soft and hard partial matching only
+ 7 all three modes
+</pre>
+If no number is given, 7 is assumed. The phrase "partial matching" means a call
+to <b>pcre2_match()</b> with either the PCRE2_PARTIAL_SOFT or the
+PCRE2_PARTIAL_HARD option set. Note that such a call may return a complete
+match; the options enable the possibility of a partial match, but do not
+require it. Note also that if you request JIT compilation only for partial
+matching (for example, /jit=2) but do not set the <b>partial</b> modifier on a
+subject line, that match will not use JIT code because none was compiled for
+non-partial matching.
+</P>
+<P>
+If JIT compilation is successful, the compiled JIT code will automatically be
+used when an appropriate type of match is run, except when incompatible
+run-time options are specified. For more details, see the
+<a href="pcre2jit.html"><b>pcre2jit</b></a>
+documentation. See also the <b>jitstack</b> modifier below for a way of
+setting the size of the JIT stack.
+</P>
+<P>
+If the <b>jitfast</b> modifier is specified, matching is done using the JIT
+"fast path" interface, <b>pcre2_jit_match()</b>, which skips some of the sanity
+checks that are done by <b>pcre2_match()</b>, and of course does not work when
+JIT is not supported. If <b>jitfast</b> is specified without <b>jit</b>, jit=7 is
+assumed.
+</P>
+<P>
+If the <b>jitverify</b> modifier is specified, information about the compiled
+pattern shows whether JIT compilation was or was not successful. If
+<b>jitverify</b> is specified without <b>jit</b>, jit=7 is assumed. If JIT
+compilation is successful when <b>jitverify</b> is set, the text "(JIT)" is
+added to the first output line after a match or non match when JIT-compiled
+code was actually used in the match.
+</P>
+<br><b>
+Setting a locale
+</b><br>
+<P>
+The <b>/locale</b> modifier must specify the name of a locale, for example:
+<pre>
+ /pattern/locale=fr_FR
+</pre>
+The given locale is set, <b>pcre2_maketables()</b> is called to build a set of
+character tables for the locale, and this is then passed to
+<b>pcre2_compile()</b> when compiling the regular expression. The same tables
+are used when matching the following subject lines. The <b>/locale</b> modifier
+applies only to the pattern on which it appears, but can be given in a
+<b>#pattern</b> command if a default is needed. Setting a locale and alternate
+character tables are mutually exclusive.
+</P>
+<br><b>
+Showing pattern memory
+</b><br>
+<P>
+The <b>/memory</b> modifier causes the size in bytes of the memory used to hold
+the compiled pattern to be output. This does not include the size of the
+<b>pcre2_code</b> block; it is just the actual compiled data. If the pattern is
+subsequently passed to the JIT compiler, the size of the JIT compiled code is
+also output. Here is an example:
+<pre>
+ re> /a(b)c/jit,memory
+ Memory allocation (code space): 21
+ Memory allocation (JIT code): 1910
+
+</PRE>
+</P>
+<br><b>
+Limiting nested parentheses
+</b><br>
+<P>
+The <b>parens_nest_limit</b> modifier sets a limit on the depth of nested
+parentheses in a pattern. Breaching the limit causes a compilation error.
+The default for the library is set when PCRE2 is built, but <b>pcre2test</b>
+sets its own default of 220, which is required for running the standard test
+suite.
+</P>
+<br><b>
+Limiting the pattern length
+</b><br>
+<P>
+The <b>max_pattern_length</b> modifier sets a limit, in code units, to the
+length of pattern that <b>pcre2_compile()</b> will accept. Breaching the limit
+causes a compilation error. The default is the largest number a PCRE2_SIZE
+variable can hold (essentially unlimited).
+</P>
+<br><b>
+Using the POSIX wrapper API
+</b><br>
+<P>
+The <b>/posix</b> modifier causes <b>pcre2test</b> to call PCRE2 via the POSIX
+wrapper API rather than its native API. This supports only the 8-bit library.
+Note that it does not imply POSIX matching semantics; for more detail see the
+<a href="pcre2posix.html"><b>pcre2posix</b></a>
+documentation. When the POSIX API is being used, the following pattern
+modifiers set options for the <b>regcomp()</b> function:
+<pre>
+ caseless REG_ICASE
+ multiline REG_NEWLINE
+ no_auto_capture REG_NOSUB
+ dotall REG_DOTALL )
+ ungreedy REG_UNGREEDY ) These options are not part of
+ ucp REG_UCP ) the POSIX standard
+ utf REG_UTF8 )
+</pre>
+The <b>regerror_buffsize</b> modifier specifies a size for the error buffer that
+is passed to <b>regerror()</b> in the event of a compilation error. For example:
+<pre>
+ /abc/posix,regerror_buffsize=20
+</pre>
+This provides a means of testing the behaviour of <b>regerror()</b> when the
+buffer is too small for the error message. If this modifier has not been set, a
+large buffer is used.
+</P>
+<P>
+The <b>aftertext</b> and <b>allaftertext</b> subject modifiers work as described
+below. All other modifiers cause an error.
+</P>
+<br><b>
+Testing the stack guard feature
+</b><br>
+<P>
+The <b>/stackguard</b> modifier is used to test the use of
+<b>pcre2_set_compile_recursion_guard()</b>, a function that is provided to
+enable stack availability to be checked during compilation (see the
+<a href="pcre2api.html"><b>pcre2api</b></a>
+documentation for details). If the number specified by the modifier is greater
+than zero, <b>pcre2_set_compile_recursion_guard()</b> is called to set up
+callback from <b>pcre2_compile()</b> to a local function. The argument it
+receives is the current nesting parenthesis depth; if this is greater than the
+value given by the modifier, non-zero is returned, causing the compilation to
+be aborted.
+</P>
+<br><b>
+Using alternative character tables
+</b><br>
+<P>
+The value specified for the <b>/tables</b> modifier must be one of the digits 0,
+1, or 2. It causes a specific set of built-in character tables to be passed to
+<b>pcre2_compile()</b>. This is used in the PCRE2 tests to check behaviour with
+different character tables. The digit specifies the tables as follows:
+<pre>
+ 0 do not pass any special character tables
+ 1 the default ASCII tables, as distributed in
+ pcre2_chartables.c.dist
+ 2 a set of tables defining ISO 8859 characters
+</pre>
+In table 2, some characters whose codes are greater than 128 are identified as
+letters, digits, spaces, etc. Setting alternate character tables and a locale
+are mutually exclusive.
+</P>
+<br><b>
+Setting certain match controls
+</b><br>
+<P>
+The following modifiers are really subject modifiers, and are described below.
+However, they may be included in a pattern's modifier list, in which case they
+are applied to every subject line that is processed with that pattern. They may
+not appear in <b>#pattern</b> commands. These modifiers do not affect the

+<br><b>
+Saving a compiled pattern

+<P>
+When a pattern with the <b>push</b> modifier is successfully compiled, it is

+<P>
+The modifiers that can appear in subject lines and the <b>#subject</b>
+command are of two types.
+</P>
+<br><b>
+Setting match options
+</b><br>
+<P>
+The following modifiers set options for <b>pcre2_match()</b> or
+<b>pcre2_dfa_match()</b>. See
+<a href="pcreapi.html"><b>pcreapi</b></a>
+for a description of their effects.
+<pre>
+ anchored set PCRE2_ANCHORED
+ dfa_restart set PCRE2_DFA_RESTART
+ dfa_shortest set PCRE2_DFA_SHORTEST
+ no_utf_check set PCRE2_NO_UTF_CHECK
+ notbol set PCRE2_NOTBOL
+ notempty set PCRE2_NOTEMPTY
+ notempty_atstart set PCRE2_NOTEMPTY_ATSTART
+ noteol set PCRE2_NOTEOL
+ partial_hard (or ph) set PCRE2_PARTIAL_HARD
+ partial_soft (or ps) set PCRE2_PARTIAL_SOFT
+</pre>
+The partial matching modifiers are provided with abbreviations because they
+appear frequently in tests.
+</P>
+<P>
+If the <b>/posix</b> modifier was present on the pattern, causing the POSIX
+wrapper API to be used, the only option-setting modifiers that have any effect
+are <b>notbol</b>, <b>notempty</b>, and <b>noteol</b>, causing REG_NOTBOL,
+REG_NOTEMPTY, and REG_NOTEOL, respectively, to be passed to <b>regexec()</b>.
+Any other modifiers cause an error.
+</P>
+<br><b>
+Setting match controls
+</b><br>
+<P>
+The following modifiers affect the matching process or request additional
+information. Some of them may also be specified on a pattern line (see above),
+in which case they apply to every subject line that is matched against that
+pattern.
+<pre>
+ aftertext show text after match
+ allaftertext show text after captures
+ allcaptures show all captures
+ allusedtext show all consulted text (non-JIT only)
+ altglobal alternative global matching
+ callout_capture show captures at callout time
+ callout_data=<n> set a value to pass via callouts
+ callout_fail=<n>[:<m>] control callout failure
+ callout_none do not supply a callout function
+ copy=<number or name> copy captured substring
+ dfa use <b>pcre2_dfa_match()</b>
+ find_limits find match and recursion limits
+ get=<number or name> extract captured substring
+ getall extract all captured substrings
+ /g global global matching
+ jitstack=<n> set size of JIT stack

+ startoffset=<n> same as offset=<n>
+ substitute_extedded use PCRE2_SUBSTITUTE_EXTENDED
+ substitute_overflow_length use PCRE2_SUBSTITUTE_OVERFLOW_LENGTH
+ substitute_unknown_unset use PCRE2_SUBSTITUTE_UNKNOWN_UNSET
+ substitute_unset_empty use PCRE2_SUBSTITUTE_UNSET_EMPTY
+ zero_terminate pass the subject as zero-terminated
+</pre>
+The effects of these modifiers are described in the following sections.
+</P>
+<br><b>
+Showing more text
+</b><br>
+<P>
+The <b>aftertext</b> modifier requests that as well as outputting the part of
+the subject string that matched the entire pattern, <b>pcre2test</b> should in
+addition output the remainder of the subject string. This is useful for tests
+where the subject contains multiple copies of the same substring. The
+<b>allaftertext</b> modifier requests the same action for captured substrings as
+well as the main matched substring. In each case the remainder is output on the
+following line with a plus character following the capture number.
+</P>
+<P>
+The <b>allusedtext</b> modifier requests that all the text that was consulted
+during a successful pattern match by the interpreter should be shown. This
+feature is not supported for JIT matching, and if requested with JIT it is
+ignored (with a warning message). Setting this modifier affects the output if
+there is a lookbehind at the start of a match, or a lookahead at the end, or if
+\K is used in the pattern. Characters that precede or follow the start and end
+of the actual match are indicated in the output by '<' or '>' characters
+underneath them. Here is an example:
+<pre>
+ re> /(?<=pqr)abc(?=xyz)/
+ data> 123pqrabcxyz456\=allusedtext
+ 0: pqrabcxyz
+ <<< >>>
+</pre>
+This shows that the matched string is "abc", with the preceding and following
+strings "pqr" and "xyz" having been consulted during the match (when processing
+the assertions).
+</P>
+<P>
+The <b>startchar</b> modifier requests that the starting character for the match
+be indicated, if it is different to the start of the matched string. The only
+time when this occurs is when \K has been processed as part of the match. In
+this situation, the output for the matched string is displayed from the
+starting character instead of from the match point, with circumflex characters
+under the earlier characters. For example:
+<pre>
+ re> /abc\Kxyz/
+ data> abcxyz\=startchar
+ 0: abcxyz
+ ^^^
+</pre>
+Unlike <b>allusedtext</b>, the <b>startchar</b> modifier can be used with JIT.
+However, these two modifiers are mutually exclusive.
+</P>
+<br><b>
+Showing the value of all capture groups
+</b><br>
+<P>
+The <b>allcaptures</b> modifier requests that the values of all potential
+captured parentheses be output after a match. By default, only those up to the
+highest one actually used in the match are output (corresponding to the return
+code from <b>pcre2_match()</b>). Groups that did not take part in the match
+are output as "<unset>".
+</P>
+<br><b>
+Testing callouts
+</b><br>
+<P>
+A callout function is supplied when <b>pcre2test</b> calls the library matching
+functions, unless <b>callout_none</b> is specified. If <b>callout_capture</b> is
+set, the current captured groups are output when a callout occurs.
+</P>
+<P>
+The <b>callout_fail</b> modifier can be given one or two numbers. If there is
+only one number, 1 is returned instead of 0 when a callout of that number is
+reached. If two numbers are given, 1 is returned when callout <n> is reached
+for the <m>th time. Note that callouts with string arguments are always given
+the number zero. See "Callouts" below for a description of the output when a
+callout it taken.
+</P>
+<P>
+The <b>callout_data</b> modifier can be given an unsigned or a negative number.
+This is set as the "user data" that is passed to the matching function, and
+passed back when the callout function is invoked. Any value other than zero is
+used as a return from <b>pcre2test</b>'s callout function.
+</P>
+<br><b>
+Finding all matches in a string
+</b><br>
+<P>
+Searching for all possible matches within a subject can be requested by the
+<b>global</b> or <b>/altglobal</b> modifier. After finding a match, the matching
+function is called again to search the remainder of the subject. The difference
+between <b>global</b> and <b>altglobal</b> is that the former uses the
+<i>start_offset</i> argument to <b>pcre2_match()</b> or <b>pcre2_dfa_match()</b>
+to start searching at a new point within the entire string (which is what Perl
+does), whereas the latter passes over a shortened subject. This makes a
+difference to the matching process if the pattern begins with a lookbehind
+assertion (including \b or \B).
+</P>
+<P>
+If an empty string is matched, the next match is done with the
+PCRE2_NOTEMPTY_ATSTART and PCRE2_ANCHORED flags set, in order to search for
+another, non-empty, match at the same point in the subject. If this match
+fails, the start offset is advanced, and the normal match is retried. This
+imitates the way Perl handles such cases when using the <b>/g</b> modifier or
+the <b>split()</b> function. Normally, the start offset is advanced by one
+character, but if the newline convention recognizes CRLF as a newline, and the
+current character is CR followed by LF, an advance of two characters occurs.
+</P>
+<br><b>
+Testing substring extraction functions
+</b><br>
+<P>
+The <b>copy</b> and <b>get</b> modifiers can be used to test the
+<b>pcre2_substring_copy_xxx()</b> and <b>pcre2_substring_get_xxx()</b> functions.
+They can be given more than once, and each can specify a group name or number,
+for example:
+<pre>
+ abcd\=copy=1,copy=3,get=G1
+</pre>
+If the <b>#subject</b> command is used to set default copy and/or get lists,
+these can be unset by specifying a negative number to cancel all numbered
+groups and an empty name to cancel all named groups.
+</P>
+<P>
+The <b>getall</b> modifier tests <b>pcre2_substring_list_get()</b>, which
+extracts all captured substrings.
+</P>
+<P>
+If the subject line is successfully matched, the substrings extracted by the
+convenience functions are output with C, G, or L after the string number
+instead of a colon. This is in addition to the normal full list. The string
+length (that is, the return from the extraction function) is given in
+parentheses after each substring, followed by the name when the extraction was
+by name.
+</P>
+<br><b>
+Testing the substitution function
+</b><br>
+<P>
+If the <b>replace</b> modifier is set, the <b>pcre2_substitute()</b> function is
+called instead of one of the matching functions. Note that replacement strings
+cannot contain commas, because a comma signifies the end of a modifier. This is
+not thought to be an issue in a test program.
+</P>
+<P>
+Unlike subject strings, <b>pcre2test</b> does not process replacement strings
+for escape sequences. In UTF mode, a replacement string is checked to see if it
+is a valid UTF-8 string. If so, it is correctly converted to a UTF string of
+the appropriate code unit width. If it is not a valid UTF-8 string, the
+individual code units are copied directly. This provides a means of passing an
+invalid UTF-8 string for testing purposes.
+</P>
+<P>
+The following modifiers set options (in additional to the normal match options)
+for <b>pcre2_substitute()</b>:
+<pre>
+ global PCRE2_SUBSTITUTE_GLOBAL
+ substitute_extended PCRE2_SUBSTITUTE_EXTENDED
+ substitute_overflow_length PCRE2_SUBSTITUTE_OVERFLOW_LENGTH
+ substitute_unknown_unset PCRE2_SUBSTITUTE_UNKNOWN_UNSET
+ substitute_unset_empty PCRE2_SUBSTITUTE_UNSET_EMPTY
+
+</PRE>
+</P>
+<P>
+After a successful substitution, the modified string is output, preceded by the
+number of replacements. This may be zero if there were no matches. Here is a
+simple example of a substitution test:
+<pre>
+ /abc/replace=xxx
+ =abc=abc=
+ 1: =xxx=abc=
+ =abc=abc=\=global
+ 2: =xxx=xxx=
+</pre>
+Subject and replacement strings should be kept relatively short (fewer than 256
+characters) for substitution tests, as fixed-size buffers are used. To make it
+easy to test for buffer overflow, if the replacement string starts with a
+number in square brackets, that number is passed to <b>pcre2_substitute()</b> as
+the size of the output buffer, with the replacement string starting at the next
+character. Here is an example that tests the edge case:
+<pre>
+ /abc/
+ 123abc123\=replace=[10]XYZ
+ 1: 123XYZ123
+ 123abc123\=replace=[9]XYZ
+ Failed: error -47: no more memory
+</pre>
+The default action of <b>pcre2_substitute()</b> is to return
+PCRE2_ERROR_NOMEMORY when the output buffer is too small. However, if the
+PCRE2_SUBSTITUTE_OVERFLOW_LENGTH option is set (by using the
+<b>substitute_overflow_length</b> modifier), <b>pcre2_substitute()</b> continues
+to go through the motions of matching and substituting, in order to compute the
+size of buffer that is required. When this happens, <b>pcre2test</b> shows the
+required buffer length (which includes space for the trailing zero) as part of
+the error message. For example:
+<pre>
+ /abc/substitute_overflow_length
+ 123abc123\=replace=[9]XYZ
+ Failed: error -47: no more memory: 10 code units are needed
+</pre>
+A replacement string is ignored with POSIX and DFA matching. Specifying partial
+matching provokes an error return ("bad option value") from
+<b>pcre2_substitute()</b>.
+</P>
+<br><b>
+Setting the JIT stack size
+</b><br>
+<P>
+The <b>jitstack</b> modifier provides a way of setting the maximum stack size
+that is used by the just-in-time optimization code. It is ignored if JIT
+optimization is not being used. The value is a number of kilobytes. Providing a
+stack that is larger than the default 32K is necessary only for very
+complicated patterns.
+</P>
+<br><b>
+Setting match and recursion limits
+</b><br>
+<P>
+The <b>match_limit</b> and <b>recursion_limit</b> modifiers set the appropriate
+limits in the match context. These values are ignored when the
+<b>find_limits</b> modifier is specified.
+</P>
+<br><b>
+Finding minimum limits
+</b><br>
+<P>
+If the <b>find_limits</b> modifier is present, <b>pcre2test</b> calls
+<b>pcre2_match()</b> several times, setting different values in the match
+context via <b>pcre2_set_match_limit()</b> and <b>pcre2_set_recursion_limit()</b>
+until it finds the minimum values for each parameter that allow
+<b>pcre2_match()</b> to complete without error.
+</P>
+<P>
+If JIT is being used, only the match limit is relevant. If DFA matching is
+being used, neither limit is relevant, and this modifier is ignored (with a
+warning message).
+</P>
+<P>
+The <i>match_limit</i> number is a measure of the amount of backtracking
+that takes place, and learning the minimum value can be instructive. For most
+simple matches, the number is quite small, but for patterns with very large
+numbers of matching possibilities, it can become large very quickly with
+increasing length of subject string. The <i>match_limit_recursion</i> number is
+a measure of how much stack (or, if PCRE2 is compiled with NO_RECURSE, how much
+heap) memory is needed to complete the match attempt.
+</P>
+<br><b>
+Showing MARK names
+</b><br>
+<P>
+The <b>mark</b> modifier causes the names from backtracking control verbs that
+are returned from calls to <b>pcre2_match()</b> to be displayed. If a mark is
+returned for a match, non-match, or partial match, <b>pcre2test</b> shows it.
+For a match, it is on a line by itself, tagged with "MK:". Otherwise, it
+is added to the non-match message.
+</P>
+<br><b>
+Showing memory usage
+</b><br>
+<P>
+The <b>memory</b> modifier causes <b>pcre2test</b> to log all memory allocation
+and freeing calls that occur during a match operation.
+</P>
+<br><b>
+Setting a starting offset
+</b><br>
+<P>
+The <b>offset</b> modifier sets an offset in the subject string at which
+matching starts. Its value is a number of code units, not characters.
+</P>
+<br><b>
+Setting an offset limit
+</b><br>
+<P>
+The <b>offset_limit</b> modifier sets a limit for unanchored matches. If a match
+cannot be found starting at or before this offset in the subject, a "no match"
+return is given. The data value is a number of code units, not characters. When
+this modifier is used, the <b>use_offset_limit</b> modifier must have been set
+for the pattern; if not, an error is generated.
+</P>
+<br><b>
+Setting the size of the output vector
+</b><br>
+<P>
+The <b>ovector</b> modifier applies only to the subject line in which it
+appears, though of course it can also be used to set a default in a
+<b>#subject</b> command. It specifies the number of pairs of offsets that are
+available for storing matching information. The default is 15.
+</P>
+<P>
+A value of zero is useful when testing the POSIX API because it causes
+<b>regexec()</b> to be called with a NULL capture vector. When not testing the
+POSIX API, a value of zero is used to cause
+<b>pcre2_match_data_create_from_pattern()</b> to be called, in order to create a
+match block of exactly the right size for the pattern. (It is not possible to
+create a match block with a zero-length ovector; there is always at least one
+pair of offsets.)
+</P>
+<br><b>
+Passing the subject as zero-terminated
+</b><br>
+<P>
+By default, the subject string is passed to a native API matching function with
+its correct length. In order to test the facility for passing a zero-terminated
+string, the <b>zero_terminate</b> modifier is provided. It causes the length to
+be passed as PCRE2_ZERO_TERMINATED. (When matching via the POSIX interface,
+this modifier has no effect, as there is no facility for passing a length.)
+</P>
+<P>
+When testing <b>pcre2_substitute()</b>, this modifier also has the effect of
+passing the replacement string as zero-terminated.
+</P>
+<br><b>
+Passing a NULL context
+</b><br>
+<P>
+Normally, <b>pcre2test</b> passes a context block to <b>pcre2_match()</b>,
+<b>pcre2_dfa_match()</b> or <b>pcre2_jit_match()</b>. If the <b>null_context</b>
+modifier is set, however, NULL is passed. This is for testing that the matching
+functions behave correctly in this case (they use default values). This
+modifier cannot be used with the <b>find_limits</b> modifier or when testing the
+substitution function.
+</P>
+<br><a name="SEC12" href="#TOC1">THE ALTERNATIVE MATCHING FUNCTION</a><br>
+<P>
+By default, <b>pcre2test</b> uses the standard PCRE2 matching function,
+<b>pcre2_match()</b> to match each subject line. PCRE2 also supports an
+alternative matching function, <b>pcre2_dfa_match()</b>, which operates in a
+different way, and has some restrictions. The differences between the two
+functions are described in the
+<a href="pcre2matching.html"><b>pcre2matching</b></a>
+documentation.
+</P>
+<P>
+If the <b>dfa</b> modifier is set, the alternative matching function is used.
+This function finds all possible matches at a given point in the subject. If,
+however, the <b>dfa_shortest</b> modifier is set, processing stops after the
+first match is found. This is always the shortest possible match.
+</P>
+<br><a name="SEC13" href="#TOC1">DEFAULT OUTPUT FROM pcre2test</a><br>
+<P>
+This section describes the output when the normal matching function,
+<b>pcre2_match()</b>, is being used.
+</P>
+<P>
+When a match succeeds, <b>pcre2test</b> outputs the list of captured substrings,
+starting with number 0 for the string that matched the whole pattern.
+Otherwise, it outputs "No match" when the return is PCRE2_ERROR_NOMATCH, or
+"Partial match:" followed by the partially matching substring when the
+return is PCRE2_ERROR_PARTIAL. (Note that this is the
+entire substring that was inspected during the partial match; it may include
+characters before the actual match start if a lookbehind assertion, \K, \b,
+or \B was involved.)
+</P>
+<P>
+For any other return, <b>pcre2test</b> outputs the PCRE2 negative error number
+and a short descriptive phrase. If the error is a failed UTF string check, the
+code unit offset of the start of the failing character is also output. Here is
+an example of an interactive <b>pcre2test</b> run.
+<pre>
+ $ pcre2test
+ PCRE2 version 9.00 2014-05-10
+
+ re> /^abc(\d+)/
+ data> abc123
+ 0: abc123
+ 1: 123
+ data> xyz
+ No match
+</pre>
+Unset capturing substrings that are not followed by one that is set are not
+shown by <b>pcre2test</b> unless the <b>allcaptures</b> modifier is specified. In
+the following example, there are two capturing substrings, but when the first
+data line is matched, the second, unset substring is not shown. An "internal"
+unset substring is shown as "<unset>", as for the second data line.
+<pre>
+ re> /(a)|(b)/
+ data> a
+ 0: a
+ 1: a
+ data> b
+ 0: b
+ 1: <unset>
+ 2: b
+</pre>
+If the strings contain any non-printing characters, they are output as \xhh
+escapes if the value is less than 256 and UTF mode is not set. Otherwise they
+are output as \x{hh...} escapes. See below for the definition of non-printing
+characters. If the <b>/aftertext</b> modifier is set, the output for substring
+0 is followed by the the rest of the subject string, identified by "0+" like
+this:
+<pre>
+ re> /cat/aftertext
+ data> cataract
+ 0: cat
+ 0+ aract
+</pre>
+If global matching is requested, the results of successive matching attempts
+are output in sequence, like this:
+<pre>
+ re> /\Bi(\w\w)/g
+ data> Mississippi
+ 0: iss
+ 1: ss
+ 0: iss
+ 1: ss
+ 0: ipp
+ 1: pp
+</pre>
+"No match" is output only if the first match attempt fails. Here is an example
+of a failure message (the offset 4 that is specified by the <b>offset</b>
+modifier is past the end of the subject string):
+<pre>
+ re> /xyz/
+ data> xyz\=offset=4
+ Error -24 (bad offset value)
+</PRE>
+</P>
+<P>
+Note that whereas patterns can be continued over several lines (a plain ">"
+prompt is used for continuations), subject lines may not. However newlines can
+be included in a subject by means of the \n escape (or \r, \r\n, etc.,
+depending on the newline sequence setting).
+</P>
+<br><a name="SEC14" href="#TOC1">OUTPUT FROM THE ALTERNATIVE MATCHING FUNCTION</a><br>
+<P>
+When the alternative matching function, <b>pcre2_dfa_match()</b>, is used, the
+output consists of a list of all the matches that start at the first point in
+the subject where there is at least one match. For example:
+<pre>
+ re> /(tang|tangerine|tan)/
+ data> yellow tangerine\=dfa
+ 0: tangerine
+ 1: tang
+ 2: tan
+</pre>
+Using the normal matching function on this data finds only "tang". The
+longest matching string is always given first (and numbered zero). After a
+PCRE2_ERROR_PARTIAL return, the output is "Partial match:", followed by the
+partially matching substring. Note that this is the entire substring that was
+inspected during the partial match; it may include characters before the actual
+match start if a lookbehind assertion, \b, or \B was involved. (\K is not
+supported for DFA matching.)
+</P>
+<P>
+If global matching is requested, the search for further matches resumes
+at the end of the longest match. For example:
+<pre>
+ re> /(tang|tangerine|tan)/g
+ data> yellow tangerine and tangy sultana\=dfa
+ 0: tangerine
+ 1: tang
+ 2: tan
+ 0: tang
+ 1: tan
+ 0: tan
+</pre>
+The alternative matching function does not support substring capture, so the
+modifiers that are concerned with captured substrings are not relevant.
+</P>
+<br><a name="SEC15" href="#TOC1">RESTARTING AFTER A PARTIAL MATCH</a><br>
+<P>
+When the alternative matching function has given the PCRE2_ERROR_PARTIAL
+return, indicating that the subject partially matched the pattern, you can
+restart the match with additional subject data by means of the
+<b>dfa_restart</b> modifier. For example:
+<pre>
+ re> /^\d?\d(jan|feb|mar|apr|may|jun|jul|aug|sep|oct|nov|dec)\d\d$/
+ data> 23ja\=P,dfa
+ Partial match: 23ja
+ data> n05\=dfa,dfa_restart
+ 0: n05
+</pre>
+For further information about partial matching, see the
+<a href="pcre2partial.html"><b>pcre2partial</b></a>
+documentation.
+</P>
+<br><a name="SEC16" href="#TOC1">CALLOUTS</a><br>
+<P>
+If the pattern contains any callout requests, <b>pcre2test</b>'s callout
+function is called during matching unless <b>callout_none</b> is specified.
+This works with both matching functions.
+</P>
+<P>
+The callout function in <b>pcre2test</b> returns zero (carry on matching) by
+default, but you can use a <b>callout_fail</b> modifier in a subject line (as
+described above) to change this and other parameters of the callout.
+</P>
+<P>
+Inserting callouts can be helpful when using <b>pcre2test</b> to check
+complicated regular expressions. For further information about callouts, see
+the
+<a href="pcre2callout.html"><b>pcre2callout</b></a>
+documentation.
+</P>
+<P>
+The output for callouts with numerical arguments and those with string
+arguments is slightly different.
+</P>
+<br><b>
+Callouts with numerical arguments
+</b><br>
+<P>
+By default, the callout function displays the callout number, the start and
+current positions in the subject text at the callout time, and the next pattern
+item to be tested. For example:
+<pre>
+ --->pqrabcdef
+ 0 ^ ^ \d
+</pre>
+This output indicates that callout number 0 occurred for a match attempt
+starting at the fourth character of the subject string, when the pointer was at
+the seventh character, and when the next pattern item was \d. Just
+one circumflex is output if the start and current positions are the same.
+</P>
+<P>
+Callouts numbered 255 are assumed to be automatic callouts, inserted as a
+result of the <b>/auto_callout</b> pattern modifier. In this case, instead of
+showing the callout number, the offset in the pattern, preceded by a plus, is
+output. For example:
+<pre>
+ re> /\d?[A-E]\*/auto_callout
+ data> E*
+ --->E*
+ +0 ^ \d?
+ +3 ^ [A-E]
+ +8 ^^ \*
+ +10 ^ ^
+ 0: E*
+</pre>
+If a pattern contains (*MARK) items, an additional line is output whenever
+a change of latest mark is passed to the callout function. For example:
+<pre>
+ re> /a(*MARK:X)bc/auto_callout
+ data> abc
+ --->abc
+ +0 ^ a
+ +1 ^^ (*MARK:X)
+ +10 ^^ b
+ Latest Mark: X
+ +11 ^ ^ c
+ +12 ^ ^
+ 0: abc
+</pre>
+The mark changes between matching "a" and "b", but stays the same for the rest
+of the match, so nothing more is output. If, as a result of backtracking, the
+mark reverts to being unset, the text "<unset>" is output.
+</P>
+<br><b>
+Callouts with string arguments
+</b><br>
+<P>
+The output for a callout with a string argument is similar, except that instead
+of outputting a callout number before the position indicators, the callout
+string and its offset in the pattern string are output before the reflection of

+<br><a name="SEC17" href="#TOC1">NON-PRINTING CHARACTERS</a><br>
+<P>
+When <b>pcre2test</b> is outputting text in the compiled version of a pattern,
+bytes other than 32-126 are always treated as non-printing characters and are
+therefore shown as hex escapes.
+</P>
+<P>
+When <b>pcre2test</b> is outputting text that is a matched part of a subject
+string, it behaves in the same way, unless a different locale has been set for
+the pattern (using the <b>/locale</b> modifier). In this case, the
+<b>isprint()</b> function is used to distinguish printing and non-printing
+characters.
+<a name="saverestore"></a></P>
+<br><a name="SEC18" href="#TOC1">SAVING AND RESTORING COMPILED PATTERNS</a><br>
+<P>
+It is possible to save compiled patterns on disc or elsewhere, and reload them
+later, subject to a number of restrictions. JIT data cannot be saved. The host
+on which the patterns are reloaded must be running the same version of PCRE2,
+with the same code unit width, and must also have the same endianness, pointer
+width and PCRE2_SIZE type. Before compiled patterns can be saved they must be
+serialized, that is, converted to a stream of bytes. A single byte stream may
+contain any number of compiled patterns, but they must all use the same
+character tables. A single copy of the tables is included in the byte stream
+(its size is 1088 bytes).
+</P>
+<P>
+The functions whose names begin with <b>pcre2_serialize_</b> are used
+for serializing and de-serializing. They are described in the
+<a href="pcre2serialize.html"><b>pcre2serialize</b></a>
+documentation. In this section we describe the features of <b>pcre2test</b> that
+can be used to test these functions.
+</P>
+<P>
+When a pattern with <b>push</b> modifier is successfully compiled, it is pushed
+onto a stack of compiled patterns, and <b>pcre2test</b> expects the next line to
+contain a new pattern (or command) instead of a subject line. By this means, a
+number of patterns can be compiled and retained. The <b>push</b> modifier is
+incompatible with <b>posix</b>, and control modifiers that act at match time are
+ignored (with a message). The <b>jitverify</b> modifier applies only at compile
+time. The command
+<pre>
+ #save <filename>
+</pre>
+causes all the stacked patterns to be serialized and the result written to the
+named file. Afterwards, all the stacked patterns are freed. The command
+<pre>
+ #load <filename>
+</pre>
+reads the data in the file, and then arranges for it to be de-serialized, with
+the resulting compiled patterns added to the pattern stack. The pattern on the
+top of the stack can be retrieved by the #pop command, which must be followed
+by lines of subjects that are to be matched with the pattern, terminated as
+usual by an empty line or end of file. This command may be followed by a
+modifier list containing only
+<a href="#controlmodifiers">control modifiers</a>
+that act after a pattern has been compiled. In particular, <b>hex</b>,
+<b>posix</b>, and <b>push</b> are not allowed, nor are any
+<a href="#optionmodifiers">option-setting modifiers.</a>
+The JIT modifiers are, however permitted. Here is an example that saves and
+reloads two patterns.
+<pre>
+ /abc/push
+ /xyz/push
+ #save tempfile
+ #load tempfile
+ #pop info
+ xyz
+
+ #pop jit,bincode
+ abc
+</pre>
+If <b>jitverify</b> is used with #pop, it does not automatically imply
+<b>jit</b>, which is different behaviour from when it is used on a pattern.

+<br><b>
+UNICODE AND UTF SUPPORT
+</b><br>
+<P>
+When PCRE2 is built with Unicode support (which is the default), it has
+knowledge of Unicode character properties and can process text strings in
+UTF-8, UTF-16, or UTF-32 format (depending on the code unit width). However, by
+default, PCRE2 assumes that one code unit is one character. To process a
+pattern as a UTF string, where a character may require more than one code unit,
+you must call
+<a href="pcre2_compile.html"><b>pcre2_compile()</b></a>
+with the PCRE2_UTF option flag, or the pattern must start with the sequence
+(*UTF). When either of these is the case, both the pattern and any subject
+strings that are matched against it are treated as UTF strings instead of
+strings of individual one-code-unit characters.
+</P>
+<P>
+If you do not need Unicode support you can build PCRE2 without it, in which
+case the library will be smaller.
+</P>
+<br><b>
+UNICODE PROPERTY SUPPORT
+</b><br>
+<P>
+When PCRE2 is built with Unicode support, the escape sequences \p{..},
+\P{..}, and \X can be used. The Unicode properties that can be tested are
+limited to the general category properties such as Lu for an upper case letter
+or Nd for a decimal number, the Unicode script names such as Arabic or Han, and
+the derived properties Any and L&. Full lists are given in the
+<a href="pcre2pattern.html"><b>pcre2pattern</b></a>
+and
+<a href="pcre2syntax.html"><b>pcre2syntax</b></a>
+documentation. Only the short names for properties are supported. For example,
+\p{L} matches a letter. Its Perl synonym, \p{Letter}, is not supported.
+Furthermore, in Perl, many properties may optionally be prefixed by "Is", for
+compatibility with Perl 5.6. PCRE does not support this.
+</P>
+<br><b>
+WIDE CHARACTERS AND UTF MODES
+</b><br>
+<P>
+Codepoints less than 256 can be specified in patterns by either braced or
+unbraced hexadecimal escape sequences (for example, \x{b3} or \xb3). Larger
+values have to use braced sequences. Unbraced octal code points up to \777 are
+also recognized; larger ones can be coded using \o{...}.
+</P>
+<P>
+In UTF modes, repeat quantifiers apply to complete UTF characters, not to
+individual code units.
+</P>
+<P>
+In UTF modes, the dot metacharacter matches one UTF character instead of a
+single code unit.
+</P>
+<P>
+The escape sequence \C can be used to match a single code unit, in a UTF mode,
+but its use can lead to some strange effects because it breaks up multi-unit
+characters (see the description of \C in the
+<a href="pcre2pattern.html"><b>pcre2pattern</b></a>
+documentation). The use of \C is not supported by the alternative matching
+function <b>pcre2_dfa_match()</b> when in UTF mode. Its use provokes a
+match-time error. The JIT optimization also does not support \C in UTF mode.
+If JIT optimization is requested for a UTF pattern that contains \C, it will
+not succeed, and so the matching will be carried out by the normal interpretive
+function.
+</P>
+<P>
+The character escapes \b, \B, \d, \D, \s, \S, \w, and \W correctly test
+characters of any code value, but, by default, the characters that PCRE2
+recognizes as digits, spaces, or word characters remain the same set as in
+non-UTF mode, all with code points less than 256. This remains true even when
+PCRE2 is built to include Unicode support, because to do otherwise would slow
+down matching in many common cases. Note that this also applies to \b
+and \B, because they are defined in terms of \w and \W. If you want
+to test for a wider sense of, say, "digit", you can use explicit Unicode
+property tests such as \p{Nd}. Alternatively, if you set the PCRE2_UCP option,
+the way that the character escapes work is changed so that Unicode properties
+are used to determine which characters match. There are more details in the
+section on
+<a href="pcre2pattern.html#genericchartypes">generic character types</a>
+in the
+<a href="pcre2pattern.html"><b>pcre2pattern</b></a>
+documentation.
+</P>
+<P>
+Similarly, characters that match the POSIX named character classes are all
+low-valued characters, unless the PCRE2_UCP option is set.
+</P>
+<P>
+However, the special horizontal and vertical white space matching escapes (\h,
+\H, \v, and \V) do match all the appropriate Unicode characters, whether or
+not PCRE2_UCP is set.
+</P>
+<P>
+Case-insensitive matching in UTF mode makes use of Unicode properties. A few
+Unicode characters such as Greek sigma have more than two codepoints that are
+case-equivalent, and these are treated as such.
+</P>
+<br><b>
+VALIDITY OF UTF STRINGS
+</b><br>
+<P>
+When the PCRE2_UTF option is set, the strings passed as patterns and subjects
+are (by default) checked for validity on entry to the relevant functions.
+If an invalid UTF string is passed, an negative error code is returned. The
+code unit offset to the offending character can be extracted from the match
+data block by calling <b>pcre2_get_startchar()</b>, which is used for this
+purpose after a UTF error.
+</P>
+<P>
+UTF-16 and UTF-32 strings can indicate their endianness by special code knows
+as a byte-order mark (BOM). The PCRE2 functions do not handle this, expecting
+strings to be in host byte order.
+</P>
+<P>
+A UTF string is checked before any other processing takes place. In the case of
+<b>pcre2_match()</b> and <b>pcre2_dfa_match()</b> calls with a non-zero starting
+offset, the check is applied only to that part of the subject that could be
+inspected during matching, and there is a check that the starting offset points
+to the first code unit of a character or to the end of the subject. If there
+are no lookbehind assertions in the pattern, the check starts at the starting
+offset. Otherwise, it starts at the length of the longest lookbehind before the
+starting offset, or at the start of the subject if there are not that many
+characters before the starting offset. Note that the sequences \b and \B are
+one-character lookbehinds.
+</P>
+<P>
+In addition to checking the format of the string, there is a check to ensure
+that all code points lie in the range U+0 to U+10FFFF, excluding the surrogate
+area. The so-called "non-character" code points are not excluded because
+Unicode corrigendum #9 makes it clear that they should not be.
+</P>
+<P>
+Characters in the "Surrogate Area" of Unicode are reserved for use by UTF-16,
+where they are used in pairs to encode code points with values greater than
+0xFFFF. The code points that are encoded by UTF-16 pairs are available
+independently in the UTF-8 and UTF-32 encodings. (In other words, the whole
+surrogate thing is a fudge for UTF-16 which unfortunately messes up UTF-8 and
+UTF-32.)
+</P>
+<P>
+In some situations, you may already know that your strings are valid, and
+therefore want to skip these checks in order to improve performance, for
+example in the case of a long subject string that is being scanned repeatedly.
+If you set the PCRE2_NO_UTF_CHECK option at compile time or at match time,
+PCRE2 assumes that the pattern or subject it is given (respectively) contains
+only valid UTF code unit sequences.
+</P>
+<P>
+Passing PCRE2_NO_UTF_CHECK to <b>pcre2_compile()</b> just disables the check for
+the pattern; it does not also apply to subject strings. If you want to disable
+the check for a subject string you must pass this option to <b>pcre2_match()</b>
+or <b>pcre2_dfa_match()</b>.
+</P>
+<P>
+If you pass an invalid UTF string when PCRE2_NO_UTF_CHECK is set, the result
+is undefined and your program may crash or loop indefinitely.
+<a name="utf8strings"></a></P>
+<br><b>
+Errors in UTF-8 strings
+</b><br>
+<P>
+The following negative error codes are given for invalid UTF-8 strings:
+<pre>
+ PCRE2_ERROR_UTF8_ERR1
+ PCRE2_ERROR_UTF8_ERR2
+ PCRE2_ERROR_UTF8_ERR3
+ PCRE2_ERROR_UTF8_ERR4
+ PCRE2_ERROR_UTF8_ERR5
+</pre>
+The string ends with a truncated UTF-8 character; the code specifies how many
+bytes are missing (1 to 5). Although RFC 3629 restricts UTF-8 characters to be
+no longer than 4 bytes, the encoding scheme (originally defined by RFC 2279)
+allows for up to 6 bytes, and this is checked first; hence the possibility of
+4 or 5 missing bytes.
+<pre>
+ PCRE2_ERROR_UTF8_ERR6
+ PCRE2_ERROR_UTF8_ERR7
+ PCRE2_ERROR_UTF8_ERR8
+ PCRE2_ERROR_UTF8_ERR9
+ PCRE2_ERROR_UTF8_ERR10
+</pre>
+The two most significant bits of the 2nd, 3rd, 4th, 5th, or 6th byte of the
+character do not have the binary value 0b10 (that is, either the most
+significant bit is 0, or the next bit is 1).
+<pre>
+ PCRE2_ERROR_UTF8_ERR11
+ PCRE2_ERROR_UTF8_ERR12
+</pre>
+A character that is valid by the RFC 2279 rules is either 5 or 6 bytes long;
+these code points are excluded by RFC 3629.
+<pre>
+ PCRE2_ERROR_UTF8_ERR13
+</pre>
+A 4-byte character has a value greater than 0x10fff; these code points are
+excluded by RFC 3629.
+<pre>
+ PCRE2_ERROR_UTF8_ERR14
+</pre>
+A 3-byte character has a value in the range 0xd800 to 0xdfff; this range of
+code points are reserved by RFC 3629 for use with UTF-16, and so are excluded
+from UTF-8.
+<pre>
+ PCRE2_ERROR_UTF8_ERR15
+ PCRE2_ERROR_UTF8_ERR16
+ PCRE2_ERROR_UTF8_ERR17
+ PCRE2_ERROR_UTF8_ERR18
+ PCRE2_ERROR_UTF8_ERR19
+</pre>
+A 2-, 3-, 4-, 5-, or 6-byte character is "overlong", that is, it codes for a
+value that can be represented by fewer bytes, which is invalid. For example,
+the two bytes 0xc0, 0xae give the value 0x2e, whose correct coding uses just
+one byte.
+<pre>
+ PCRE2_ERROR_UTF8_ERR20
+</pre>
+The two most significant bits of the first byte of a character have the binary
+value 0b10 (that is, the most significant bit is 1 and the second is 0). Such a
+byte can only validly occur as the second or subsequent byte of a multi-byte
+character.
+<pre>
+ PCRE2_ERROR_UTF8_ERR21
+</pre>
+The first byte of a character has the value 0xfe or 0xff. These values can
+never occur in a valid UTF-8 string.

+.SH NAME
+PCRE2 - Perl-compatible regular expressions (revised API)
+.SH INTRODUCTION
+.rs
+.sp
+PCRE2 is the name used for a revised API for the PCRE library, which is a set
+of functions, written in C, that implement regular expression pattern matching
+using the same syntax and semantics as Perl, with just a few differences. Some
+features that appeared in Python and the original PCRE before they appeared in
+Perl are also available using the Python syntax. There is also some support for
+one or two .NET and Oniguruma syntax items, and there are options for
+requesting some minor changes that give better ECMAScript (aka JavaScript)
+compatibility.
+.P
+The source code for PCRE2 can be compiled to support 8-bit, 16-bit, or 32-bit
+code units, which means that up to three separate libraries may be installed.
+The original work to extend PCRE to 16-bit and 32-bit code units was done by
+Zoltan Herczeg and Christian Persch, respectively. In all three cases, strings
+can be interpreted either as one character per code unit, or as UTF-encoded
+Unicode, with support for Unicode general category properties. Unicode support
+is optional at build time (but is the default). However, processing strings as
+UTF code units must be enabled explicitly at run time. The version of Unicode
+in use can be discovered by running
+.sp
+ pcre2test -C
+.P
+The three libraries contain identical sets of functions, with names ending in
+_8, _16, or _32, respectively (for example, \fBpcre2_compile_8()\fP). However,
+by defining PCRE2_CODE_UNIT_WIDTH to be 8, 16, or 32, a program that uses just
+one code unit width can be written using generic names such as
+\fBpcre2_compile()\fP, and the documentation is written assuming that this is
+the case.
+.P
+In addition to the Perl-compatible matching function, PCRE2 contains an
+alternative function that matches the same compiled patterns in a different
+way. In certain circumstances, the alternative function has some advantages.
+For a discussion of the two matching algorithms, see the
+.\" HREF
+\fBpcre2matching\fP
+.\"
+page.
+.P
+Details of exactly which Perl regular expression features are and are not
+supported by PCRE2 are given in separate documents. See the
+.\" HREF
+\fBpcre2pattern\fP
+.\"
+and
+.\" HREF
+\fBpcre2compat\fP
+.\"
+pages. There is a syntax summary in the
+.\" HREF
+\fBpcre2syntax\fP
+.\"
+page.
+.P
+Some features of PCRE2 can be included, excluded, or changed when the library
+is built. The
+.\" HREF
+\fBpcre2_config()\fP
+.\"
+function makes it possible for a client to discover which features are
+available. The features themselves are described in the
+.\" HREF
+\fBpcre2build\fP
+.\"
+page. Documentation about building PCRE2 for various operating systems can be
+found in the
+.\" HTML <a href="README.txt">
+.\" </a>
+\fBREADME\fP
+.\"
+and
+.\" HTML <a href="NON-AUTOTOOLS-BUILD.txt">
+.\" </a>
+\fBNON-AUTOTOOLS_BUILD\fP
+.\"
+files in the source distribution.
+.P
+The libraries contains a number of undocumented internal functions and data
+tables that are used by more than one of the exported external functions, but
+which are not intended for use by external callers. Their names all begin with
+"_pcre2", which hopefully will not provoke any name clashes. In some
+environments, it is possible to control which external symbols are exported
+when a shared library is built, and in these cases the undocumented symbols are
+not exported.
+.
+.
+.SH "SECURITY CONSIDERATIONS"
+.rs
+.sp
+If you are using PCRE2 in a non-UTF application that permits users to supply
+arbitrary patterns for compilation, you should be aware of a feature that
+allows users to turn on UTF support from within a pattern. For example, an
+8-bit pattern that begins with "(*UTF)" turns on UTF-8 mode, which interprets
+patterns and subjects as strings of UTF-8 code units instead of individual
+8-bit characters. This causes both the pattern and any data against which it is
+matched to be checked for UTF-8 validity. If the data string is very long, such
+a check might use sufficiently many resources as to cause your application to
+lose performance.
+.P
+One way of guarding against this possibility is to use the
+\fBpcre2_pattern_info()\fP function to check the compiled pattern's options for
+PCRE2_UTF. Alternatively, you can set the PCRE2_NEVER_UTF option when calling
+\fBpcre2_compile()\fP. This causes an compile time error if a pattern contains
+a UTF-setting sequence.
+.P
+The use of Unicode properties for character types such as \ed can also be
+enabled from within the pattern, by specifying "(*UCP)". This feature can be
+disallowed by setting the PCRE2_NEVER_UCP option.
+.P
+If your application is one that supports UTF, be aware that validity checking
+can take time. If the same data string is to be matched many times, you can use
+the PCRE2_NO_UTF_CHECK option for the second and subsequent matches to avoid
+running redundant checks.
+.P
+The use of the \eC escape sequence in a UTF-8 or UTF-16 pattern can lead to
+problems, because it may leave the current matching point in the middle of a
+multi-code-unit character. The PCRE2_NEVER_BACKSLASH_C option can be used by an
+application to lock out the use of \eC, causing a compile-time error if it is
+encountered. It is also possible to build PCRE2 with the use of \eC permanently
+disabled.
+.P
+Another way that performance can be hit is by running a pattern that has a very
+large search tree against a string that will never match. Nested unlimited
+repeats in a pattern are a common example. PCRE2 provides some protection
+against this: see the \fBpcre2_set_match_limit()\fP function in the
+.\" HREF
+\fBpcre2api\fP
+.\"
+page.
+.
+.
+.SH "USER DOCUMENTATION"
+.rs
+.sp
+The user documentation for PCRE2 comprises a number of different sections. In
+the "man" format, each of these is a separate "man page". In the HTML format,
+each is a separate page, linked from the index page. In the plain text format,

+NAME
+ PCRE2 - Perl-compatible regular expressions (revised API)
+
+INTRODUCTION
+
+ PCRE2 is the name used for a revised API for the PCRE library, which is
+ a set of functions, written in C, that implement regular expression
+ pattern matching using the same syntax and semantics as Perl, with just
+ a few differences. Some features that appeared in Python and the origi-
+ nal PCRE before they appeared in Perl are also available using the
+ Python syntax. There is also some support for one or two .NET and Onig-
+ uruma syntax items, and there are options for requesting some minor
+ changes that give better ECMAScript (aka JavaScript) compatibility.
+
+ The source code for PCRE2 can be compiled to support 8-bit, 16-bit, or
+ 32-bit code units, which means that up to three separate libraries may
+ be installed. The original work to extend PCRE to 16-bit and 32-bit
+ code units was done by Zoltan Herczeg and Christian Persch, respec-
+ tively. In all three cases, strings can be interpreted either as one
+ character per code unit, or as UTF-encoded Unicode, with support for
+ Unicode general category properties. Unicode support is optional at
+ build time (but is the default). However, processing strings as UTF
+ code units must be enabled explicitly at run time. The version of Uni-
+ code in use can be discovered by running
+
+ pcre2test -C
+
+ The three libraries contain identical sets of functions, with names
+ ending in _8, _16, or _32, respectively (for example, pcre2_com-
+ pile_8()). However, by defining PCRE2_CODE_UNIT_WIDTH to be 8, 16, or
+ 32, a program that uses just one code unit width can be written using
+ generic names such as pcre2_compile(), and the documentation is written
+ assuming that this is the case.
+
+ In addition to the Perl-compatible matching function, PCRE2 contains an
+ alternative function that matches the same compiled patterns in a dif-
+ ferent way. In certain circumstances, the alternative function has some
+ advantages. For a discussion of the two matching algorithms, see the
+ pcre2matching page.
+
+ Details of exactly which Perl regular expression features are and are
+ not supported by PCRE2 are given in separate documents. See the
+ pcre2pattern and pcre2compat pages. There is a syntax summary in the
+ pcre2syntax page.
+
+ Some features of PCRE2 can be included, excluded, or changed when the
+ library is built. The pcre2_config() function makes it possible for a
+ client to discover which features are available. The features them-
+ selves are described in the pcre2build page. Documentation about build-
+ ing PCRE2 for various operating systems can be found in the README and
+ NON-AUTOTOOLS_BUILD files in the source distribution.
+
+ The libraries contains a number of undocumented internal functions and
+ data tables that are used by more than one of the exported external
+ functions, but which are not intended for use by external callers.
+ Their names all begin with "_pcre2", which hopefully will not provoke
+ any name clashes. In some environments, it is possible to control which
+ external symbols are exported when a shared library is built, and in
+ these cases the undocumented symbols are not exported.
+
+
+SECURITY CONSIDERATIONS
+
+ If you are using PCRE2 in a non-UTF application that permits users to
+ supply arbitrary patterns for compilation, you should be aware of a
+ feature that allows users to turn on UTF support from within a pattern.
+ For example, an 8-bit pattern that begins with "(*UTF)" turns on UTF-8
+ mode, which interprets patterns and subjects as strings of UTF-8 code
+ units instead of individual 8-bit characters. This causes both the pat-
+ tern and any data against which it is matched to be checked for UTF-8
+ validity. If the data string is very long, such a check might use suf-
+ ficiently many resources as to cause your application to lose perfor-
+ mance.
+
+ One way of guarding against this possibility is to use the pcre2_pat-
+ tern_info() function to check the compiled pattern's options for
+ PCRE2_UTF. Alternatively, you can set the PCRE2_NEVER_UTF option when
+ calling pcre2_compile(). This causes an compile time error if a pattern
+ contains a UTF-setting sequence.
+
+ The use of Unicode properties for character types such as \d can also
+ be enabled from within the pattern, by specifying "(*UCP)". This fea-
+ ture can be disallowed by setting the PCRE2_NEVER_UCP option.
+
+ If your application is one that supports UTF, be aware that validity
+ checking can take time. If the same data string is to be matched many
+ times, you can use the PCRE2_NO_UTF_CHECK option for the second and
+ subsequent matches to avoid running redundant checks.
+
+ The use of the \C escape sequence in a UTF-8 or UTF-16 pattern can lead
+ to problems, because it may leave the current matching point in the
+ middle of a multi-code-unit character. The PCRE2_NEVER_BACKSLASH_C
+ option can be used by an application to lock out the use of \C, causing
+ a compile-time error if it is encountered. It is also possible to build
+ PCRE2 with the use of \C permanently disabled.
+
+ Another way that performance can be hit is by running a pattern that
+ has a very large search tree against a string that will never match.
+ Nested unlimited repeats in a pattern are a common example. PCRE2 pro-
+ vides some protection against this: see the pcre2_set_match_limit()
+ function in the pcre2api page.
+
+
+USER DOCUMENTATION
+
+ The user documentation for PCRE2 comprises a number of different sec-
+ tions. In the "man" format, each of these is a separate "man page". In
+ the HTML format, each is a separate page, linked from the index page.
+ In the plain text format, the descriptions of the pcre2grep and
+ pcre2test programs are in files called pcre2grep.txt and pcre2test.txt,
+ respectively. The remaining sections, except for the pcre2demo section
+ (which is a program listing), and the short pages for individual func-
+ tions, are concatenated in pcre2.txt, for ease of searching. The sec-

+
+
+PCRE2 8-BIT, 16-BIT, AND 32-BIT LIBRARIES
+
+ There are three PCRE2 libraries, supporting 8-bit, 16-bit, and 32-bit
+ code units, respectively. However, there is just one header file,
+ pcre2.h. This contains the function prototypes and other definitions
+ for all three libraries. One, two, or all three can be installed simul-
+ taneously. On Unix-like systems the libraries are called libpcre2-8,
+ libpcre2-16, and libpcre2-32, and they can also co-exist with the orig-
+ inal PCRE libraries.
+
+ Character strings are passed to and from a PCRE2 library as a sequence
+ of unsigned integers in code units of the appropriate width. Every
+ PCRE2 function comes in three different forms, one for each library,
+ for example:
+
+ pcre2_compile_8()
+ pcre2_compile_16()
+ pcre2_compile_32()
+
+ There are also three different sets of data types:
+
+ PCRE2_UCHAR8, PCRE2_UCHAR16, PCRE2_UCHAR32
+ PCRE2_SPTR8, PCRE2_SPTR16, PCRE2_SPTR32
+
+ The UCHAR types define unsigned code units of the appropriate widths.
+ For example, PCRE2_UCHAR16 is usually defined as `uint16_t'. The SPTR
+ types are constant pointers to the equivalent UCHAR types, that is,
+ they are pointers to vectors of unsigned code units.
+
+ Many applications use only one code unit width. For their convenience,
+ macros are defined whose names are the generic forms such as pcre2_com-
+ pile() and PCRE2_SPTR. These macros use the value of the macro
+ PCRE2_CODE_UNIT_WIDTH to generate the appropriate width-specific func-
+ tion and macro names. PCRE2_CODE_UNIT_WIDTH is not defined by default.
+ An application must define it to be 8, 16, or 32 before including
+ pcre2.h in order to make use of the generic names.
+
+ Applications that use more than one code unit width can be linked with
+ more than one PCRE2 library, but must define PCRE2_CODE_UNIT_WIDTH to
+ be 0 before including pcre2.h, and then use the real function names.
+ Any code that is to be included in an environment where the value of
+ PCRE2_CODE_UNIT_WIDTH is unknown should also use the real function
+ names. (Unfortunately, it is not possible in C code to save and restore
+ the value of a macro.)
+
+ If PCRE2_CODE_UNIT_WIDTH is not defined before including pcre2.h, a
+ compiler error occurs.
+
+ When using multiple libraries in an application, you must take care
+ when processing any particular pattern to use only functions from a
+ single library. For example, if you want to run a match using a pat-
+ tern that was compiled with pcre2_compile_16(), you must do so with
+ pcre2_match_16(), not pcre2_match_8().
+
+ In the function summaries above, and in the rest of this document and
+ other PCRE2 documents, functions and data types are described using
+ their generic names, without the 8, 16, or 32 suffix.
+
+
+PCRE2 API OVERVIEW
+
+ PCRE2 has its own native API, which is described in this document.
+ There are also some wrapper functions for the 8-bit library that corre-
+ spond to the POSIX regular expression API, but they do not give access
+ to all the functionality. They are described in the pcre2posix documen-
+ tation. Both these APIs define a set of C function calls.
+
+ The native API C data types, function prototypes, option values, and
+ error codes are defined in the header file pcre2.h, which contains def-
+ initions of PCRE2_MAJOR and PCRE2_MINOR, the major and minor release
+ numbers for the library. Applications can use these to include support
+ for different releases of PCRE2.
+
+ In a Windows environment, if you want to statically link an application
+ program against a non-dll PCRE2 library, you must define PCRE2_STATIC
+ before including pcre2.h.
+
+ The functions pcre2_compile(), and pcre2_match() are used for compiling
+ and matching regular expressions in a Perl-compatible manner. A sample
+ program that demonstrates the simplest way of using them is provided in
+ the file called pcre2demo.c in the PCRE2 source distribution. A listing
+ of this program is given in the pcre2demo documentation, and the
+ pcre2sample documentation describes how to compile and run it.
+
+ Just-in-time compiler support is an optional feature of PCRE2 that can
+ be built in appropriate hardware environments. It greatly speeds up the
+ matching performance of many patterns. Programs can request that it be
+ used if available, by calling pcre2_jit_compile() after a pattern has
+ been successfully compiled by pcre2_compile(). This does nothing if JIT
+ support is not available.
+
+ More complicated programs might need to make use of the specialist
+ functions pcre2_jit_stack_create(), pcre2_jit_stack_free(), and
+ pcre2_jit_stack_assign() in order to control the JIT code's memory
+ usage.
+
+ JIT matching is automatically used by pcre2_match() if it is available.
+ There is also a direct interface for JIT matching, which gives improved
+ performance. The JIT-specific functions are discussed in the pcre2jit
+ documentation.
+
+ A second matching function, pcre2_dfa_match(), which is not Perl-com-
+ patible, is also provided. This uses a different algorithm for the
+ matching. The alternative algorithm finds all possible matches (at a
+ given point in the subject), and scans the subject just once (unless
+ there are lookbehind assertions). However, this algorithm does not
+ return captured substrings. A description of the two matching algo-
+ rithms and their advantages and disadvantages is given in the
+ pcre2matching documentation. There is no JIT support for
+ pcre2_dfa_match().
+
+ In addition to the main compiling and matching functions, there are
+ convenience functions for extracting captured substrings from a subject
+ string that has been matched by pcre2_match(). They are:
+
+ pcre2_substring_copy_byname()
+ pcre2_substring_copy_bynumber()
+ pcre2_substring_get_byname()
+ pcre2_substring_get_bynumber()
+ pcre2_substring_list_get()
+ pcre2_substring_length_byname()
+ pcre2_substring_length_bynumber()
+ pcre2_substring_nametable_scan()
+ pcre2_substring_number_from_name()
+
+ pcre2_substring_free() and pcre2_substring_list_free() are also pro-
+ vided, to free the memory used for extracted strings.
+
+ The function pcre2_substitute() can be called to match a pattern and
+ return a copy of the subject string with substitutions for parts that
+ were matched.
+
+ Finally, there are functions for finding out information about a com-
+ piled pattern (pcre2_pattern_info()) and about the configuration with
+ which PCRE2 was built (pcre2_config()).
+
+
+STRING LENGTHS AND OFFSETS
+
+ The PCRE2 API uses string lengths and offsets into strings of code
+ units in several places. These values are always of type PCRE2_SIZE,
+ which is an unsigned integer type, currently always defined as size_t.
+ The largest value that can be stored in such a type (that is
+ ~(PCRE2_SIZE)0) is reserved as a special indicator for zero-terminated
+ strings and unset offsets. Therefore, the longest string that can be
+ handled is one less than this maximum.
+
+
+NEWLINES
+
+ PCRE2 supports five different conventions for indicating line breaks in
+ strings: a single CR (carriage return) character, a single LF (line-
+ feed) character, the two-character sequence CRLF, any of the three pre-
+ ceding, or any Unicode newline sequence. The Unicode newline sequences
+ are the three just mentioned, plus the single characters VT (vertical
+ tab, U+000B), FF (form feed, U+000C), NEL (next line, U+0085), LS (line
+ separator, U+2028), and PS (paragraph separator, U+2029).
+
+ Each of the first three conventions is used by at least one operating
+ system as its standard newline sequence. When PCRE2 is built, a default
+ can be specified. The default default is LF, which is the Unix stan-
+ dard. However, the newline convention can be changed by an application
+ when calling pcre2_compile(), or it can be specified by special text at
+ the start of the pattern itself; this overrides any other settings. See
+ the pcre2pattern page for details of the special character sequences.
+
+ In the PCRE2 documentation the word "newline" is used to mean "the
+ character or pair of characters that indicate a line break". The choice
+ of newline convention affects the handling of the dot, circumflex, and
+ dollar metacharacters, the handling of #-comments in /x mode, and, when
+ CRLF is a recognized line ending sequence, the match position advance-
+ ment for a non-anchored pattern. There is more detail about this in the
+ section on pcre2_match() options below.
+
+ The choice of newline convention does not affect the interpretation of
+ the \n or \r escape sequences, nor does it affect what \R matches; this
+ has its own separate convention.
+
+
+MULTITHREADING
+
+ In a multithreaded application it is important to keep thread-specific
+ data separate from data that can be shared between threads. The PCRE2
+ library code itself is thread-safe: it contains no static or global
+ variables. The API is designed to be fairly simple for non-threaded
+ applications while at the same time ensuring that multithreaded appli-
+ cations can use it.
+
+ There are several different blocks of data that are used to pass infor-
+ mation between the application and the PCRE2 libraries.
+
+ (1) A pointer to the compiled form of a pattern is returned to the user
+ when pcre2_compile() is successful. The data in the compiled pattern is
+ fixed, and does not change when the pattern is matched. Therefore, it
+ is thread-safe, that is, the same compiled pattern can be used by more
+ than one thread simultaneously. An application can compile all its pat-
+ terns at the start, before forking off multiple threads that use them.
+ However, if the just-in-time optimization feature is being used, it
+ needs separate memory stack areas for each thread. See the pcre2jit
+ documentation for more details.
+
+ (2) The next section below introduces the idea of "contexts" in which
+ PCRE2 functions are called. A context is nothing more than a collection
+ of parameters that control the way PCRE2 operates. Grouping a number of
+ parameters together in a context is a convenient way of passing them to
+ a PCRE2 function without using lots of arguments. The parameters that
+ are stored in contexts are in some sense "advanced features" of the
+ API. Many straightforward applications will not need to use contexts.
+
+ In a multithreaded application, if the parameters in a context are val-
+ ues that are never changed, the same context can be used by all the
+ threads. However, if any thread needs to change any value in a context,
+ it must make its own thread-specific copy.
+
+ (3) The matching functions need a block of memory for working space and
+ for storing the results of a match. This includes details of what was
+ matched, as well as additional information such as the name of a
+ (*MARK) setting. Each thread must provide its own version of this mem-
+ ory.
+
+
+PCRE2 CONTEXTS
+
+ Some PCRE2 functions have a lot of parameters, many of which are used
+ only by specialist applications, for example, those that use custom
+ memory management or non-standard character tables. To keep function
+ argument lists at a reasonable size, and at the same time to keep the
+ API extensible, "uncommon" parameters are passed to certain functions
+ in a context instead of directly. A context is just a block of memory
+ that holds the parameter values. Applications that do not need to
+ adjust any of the context parameters can pass NULL when a context
+ pointer is required.
+
+ There are three different types of context: a general context that is
+ relevant for several PCRE2 operations, a compile-time context, and a
+ match-time context.
+
+ The general context
+
+ At present, this context just contains pointers to (and data for)
+ external memory management functions that are called from several
+ places in the PCRE2 library. The context is named `general' rather than
+ specifically `memory' because in future other fields may be added. If
+ you do not want to supply your own custom memory management functions,
+ you do not need to bother with a general context. A general context is
+ created by:
+
+ pcre2_general_context *pcre2_general_context_create(
+ void *(*private_malloc)(PCRE2_SIZE, void *),
+ void (*private_free)(void *, void *), void *memory_data);
+
+ The two function pointers specify custom memory management functions,
+ whose prototypes are:
+
+ void *private_malloc(PCRE2_SIZE, void *);
+ void private_free(void *, void *);
+
+ Whenever code in PCRE2 calls these functions, the final argument is the
+ value of memory_data. Either of the first two arguments of the creation
+ function may be NULL, in which case the system memory management func-
+ tions malloc() and free() are used. (This is not currently useful, as
+ there are no other fields in a general context, but in future there
+ might be.) The private_malloc() function is used (if supplied) to
+ obtain memory for storing the context, and all three values are saved
+ as part of the context.
+
+ Whenever PCRE2 creates a data block of any kind, the block contains a
+ pointer to the free() function that matches the malloc() function that
+ was used. When the time comes to free the block, this function is
+ called.
+
+ A general context can be copied by calling:
+
+ pcre2_general_context *pcre2_general_context_copy(
+ pcre2_general_context *gcontext);
+
+ The memory used for a general context should be freed by calling:
+
+ void pcre2_general_context_free(pcre2_general_context *gcontext);
+
+
+ The compile context
+
+ A compile context is required if you want to change the default values
+ of any of the following compile-time parameters:
+
+ What \R matches (Unicode newlines or CR, LF, CRLF only)
+ PCRE2's character tables
+ The newline character sequence
+ The compile time nested parentheses limit
+ The maximum length of the pattern string
+ An external function for stack checking
+
+ A compile context is also required if you are using custom memory man-
+ agement. If none of these apply, just pass NULL as the context argu-
+ ment of pcre2_compile().
+
+ A compile context is created, copied, and freed by the following func-
+ tions:
+
+ pcre2_compile_context *pcre2_compile_context_create(
+ pcre2_general_context *gcontext);
+
+ pcre2_compile_context *pcre2_compile_context_copy(
+ pcre2_compile_context *ccontext);
+
+ void pcre2_compile_context_free(pcre2_compile_context *ccontext);
+
+ A compile context is created with default values for its parameters.
+ These can be changed by calling the following functions, which return 0
+ on success, or PCRE2_ERROR_BADDATA if invalid data is detected.
+
+ int pcre2_set_bsr(pcre2_compile_context *ccontext,
+ uint32_t value);
+
+ The value must be PCRE2_BSR_ANYCRLF, to specify that \R matches only
+ CR, LF, or CRLF, or PCRE2_BSR_UNICODE, to specify that \R matches any
+ Unicode line ending sequence. The value is used by the JIT compiler and
+ by the two interpreted matching functions, pcre2_match() and
+ pcre2_dfa_match().
+
+ int pcre2_set_character_tables(pcre2_compile_context *ccontext,
+ const unsigned char *tables);
+
+ The value must be the result of a call to pcre2_maketables(), whose
+ only argument is a general context. This function builds a set of char-
+ acter tables in the current locale.
+
+ int pcre2_set_max_pattern_length(pcre2_compile_context *ccontext,
+ PCRE2_SIZE value);
+
+ This sets a maximum length, in code units, for the pattern string that
+ is to be compiled. If the pattern is longer, an error is generated.
+ This facility is provided so that applications that accept patterns
+ from external sources can limit their size. The default is the largest
+ number that a PCRE2_SIZE variable can hold, which is effectively unlim-
+ ited.
+
+ int pcre2_set_newline(pcre2_compile_context *ccontext,
+ uint32_t value);
+
+ This specifies which characters or character sequences are to be recog-
+ nized as newlines. The value must be one of PCRE2_NEWLINE_CR (carriage
+ return only), PCRE2_NEWLINE_LF (linefeed only), PCRE2_NEWLINE_CRLF (the
+ two-character sequence CR followed by LF), PCRE2_NEWLINE_ANYCRLF (any
+ of the above), or PCRE2_NEWLINE_ANY (any Unicode newline sequence).
+
+ When a pattern is compiled with the PCRE2_EXTENDED option, the value of
+ this parameter affects the recognition of white space and the end of
+ internal comments starting with #. The value is saved with the compiled
+ pattern for subsequent use by the JIT compiler and by the two inter-
+ preted matching functions, pcre2_match() and pcre2_dfa_match().
+
+ int pcre2_set_parens_nest_limit(pcre2_compile_context *ccontext,
+ uint32_t value);
+
+ This parameter ajusts the limit, set when PCRE2 is built (default 250),
+ on the depth of parenthesis nesting in a pattern. This limit stops
+ rogue patterns using up too much system stack when being compiled.
+
+ int pcre2_set_compile_recursion_guard(pcre2_compile_context *ccontext,
+ int (*guard_function)(uint32_t, void *), void *user_data);
+
+ There is at least one application that runs PCRE2 in threads with very
+ limited system stack, where running out of stack is to be avoided at
+ all costs. The parenthesis limit above cannot take account of how much
+ stack is actually available. For a finer control, you can supply a
+ function that is called whenever pcre2_compile() starts to compile a
+ parenthesized part of a pattern. This function can check the actual
+ stack size (or anything else that it wants to, of course).
+
+ The first argument to the callout function gives the current depth of
+ nesting, and the second is user data that is set up by the last argu-
+ ment of pcre2_set_compile_recursion_guard(). The callout function
+ should return zero if all is well, or non-zero to force an error.
+
+ The match context
+
+ A match context is required if you want to change the default values of
+ any of the following match-time parameters:
+
+ A callout function
+ The offset limit for matching an unanchored pattern
+ The limit for calling match() (see below)
+ The limit for calling match() recursively
+
+ A match context is also required if you are using custom memory manage-
+ ment. If none of these apply, just pass NULL as the context argument
+ of pcre2_match(), pcre2_dfa_match(), or pcre2_jit_match().
+
+ A match context is created, copied, and freed by the following func-
+ tions:
+
+ pcre2_match_context *pcre2_match_context_create(
+ pcre2_general_context *gcontext);
+
+ pcre2_match_context *pcre2_match_context_copy(
+ pcre2_match_context *mcontext);
+
+ void pcre2_match_context_free(pcre2_match_context *mcontext);
+
+ A match context is created with default values for its parameters.
+ These can be changed by calling the following functions, which return 0
+ on success, or PCRE2_ERROR_BADDATA if invalid data is detected.
+
+ int pcre2_set_callout(pcre2_match_context *mcontext,
+ int (*callout_function)(pcre2_callout_block *, void *),
+ void *callout_data);
+
+ This sets up a "callout" function, which PCRE2 will call at specified
+ points during a matching operation. Details are given in the pcre2call-
+ out documentation.
+
+ int pcre2_set_offset_limit(pcre2_match_context *mcontext,
+ PCRE2_SIZE value);
+
+ The offset_limit parameter limits how far an unanchored search can
+ advance in the subject string. The default value is PCRE2_UNSET. The
+ pcre2_match() and pcre2_dfa_match() functions return
+ PCRE2_ERROR_NOMATCH if a match with a starting point before or at the
+ given offset is not found. For example, if the pattern /abc/ is matched
+ against "123abc" with an offset limit less than 3, the result is
+ PCRE2_ERROR_NO_MATCH. A match can never be found if the startoffset
+ argument of pcre2_match() or pcre2_dfa_match() is greater than the off-
+ set limit.
+
+ When using this facility, you must set PCRE2_USE_OFFSET_LIMIT when
+ calling pcre2_compile() so that when JIT is in use, different code can
+ be compiled. If a match is started with a non-default match limit when
+ PCRE2_USE_OFFSET_LIMIT is not set, an error is generated.
+
+ The offset limit facility can be used to track progress when searching
+ large subject strings. See also the PCRE2_FIRSTLINE option, which
+ requires a match to start within the first line of the subject. If this
+ is set with an offset limit, a match must occur in the first line and
+ also within the offset limit. In other words, whichever limit comes
+ first is used.
+
+ int pcre2_set_match_limit(pcre2_match_context *mcontext,
+ uint32_t value);
+
+ The match_limit parameter provides a means of preventing PCRE2 from
+ using up too many resources when processing patterns that are not going
+ to match, but which have a very large number of possibilities in their
+ search trees. The classic example is a pattern that uses nested unlim-
+ ited repeats.
+
+ Internally, pcre2_match() uses a function called match(), which it
+ calls repeatedly (sometimes recursively). The limit set by match_limit
+ is imposed on the number of times this function is called during a
+ match, which has the effect of limiting the amount of backtracking that
+ can take place. For patterns that are not anchored, the count restarts
+ from zero for each position in the subject string. This limit is not
+ relevant to pcre2_dfa_match(), which ignores it.
+
+ When pcre2_match() is called with a pattern that was successfully pro-
+ cessed by pcre2_jit_compile(), the way in which matching is executed is
+ entirely different. However, there is still the possibility of runaway
+ matching that goes on for a very long time, and so the match_limit
+ value is also used in this case (but in a different way) to limit how
+ long the matching can continue.
+
+ The default value for the limit can be set when PCRE2 is built; the
+ default default is 10 million, which handles all but the most extreme
+ cases. If the limit is exceeded, pcre2_match() returns
+ PCRE2_ERROR_MATCHLIMIT. A value for the match limit may also be sup-
+ plied by an item at the start of a pattern of the form
+
+ (*LIMIT_MATCH=ddd)
+
+ where ddd is a decimal number. However, such a setting is ignored
+ unless ddd is less than the limit set by the caller of pcre2_match()
+ or, if no such limit is set, less than the default.
+
+ int pcre2_set_recursion_limit(pcre2_match_context *mcontext,
+ uint32_t value);
+
+ The recursion_limit parameter is similar to match_limit, but instead of
+ limiting the total number of times that match() is called, it limits
+ the depth of recursion. The recursion depth is a smaller number than
+ the total number of calls, because not all calls to match() are recur-
+ sive. This limit is of use only if it is set smaller than match_limit.
+
+ Limiting the recursion depth limits the amount of system stack that can
+ be used, or, when PCRE2 has been compiled to use memory on the heap
+ instead of the stack, the amount of heap memory that can be used. This
+ limit is not relevant, and is ignored, when matching is done using JIT
+ compiled code or by the pcre2_dfa_match() function.
+
+ The default value for recursion_limit can be set when PCRE2 is built;
+ the default default is the same value as the default for match_limit.
+ If the limit is exceeded, pcre2_match() returns PCRE2_ERROR_RECURSION-
+ LIMIT. A value for the recursion limit may also be supplied by an item
+ at the start of a pattern of the form
+
+ (*LIMIT_RECURSION=ddd)
+
+ where ddd is a decimal number. However, such a setting is ignored
+ unless ddd is less than the limit set by the caller of pcre2_match()
+ or, if no such limit is set, less than the default.
+
+ int pcre2_set_recursion_memory_management(
+ pcre2_match_context *mcontext,
+ void *(*private_malloc)(PCRE2_SIZE, void *),
+ void (*private_free)(void *, void *), void *memory_data);
+
+ This function sets up two additional custom memory management functions
+ for use by pcre2_match() when PCRE2 is compiled to use the heap for
+ remembering backtracking data, instead of recursive function calls that
+ use the system stack. There is a discussion about PCRE2's stack usage
+ in the pcre2stack documentation. See the pcre2build documentation for
+ details of how to build PCRE2.
+
+ Using the heap for recursion is a non-standard way of building PCRE2,
+ for use in environments that have limited stacks. Because of the
+ greater use of memory management, pcre2_match() runs more slowly. Func-
+ tions that are different to the general custom memory functions are
+ provided so that special-purpose external code can be used for this
+ case, because the memory blocks are all the same size. The blocks are
+ retained by pcre2_match() until it is about to exit so that they can be
+ re-used when possible during the match. In the absence of these func-
+ tions, the normal custom memory management functions are used, if sup-
+ plied, otherwise the system functions.
+
+
+CHECKING BUILD-TIME OPTIONS
+
+ int pcre2_config(uint32_t what, void *where);
+
+ The function pcre2_config() makes it possible for a PCRE2 client to
+ discover which optional features have been compiled into the PCRE2
+ library. The pcre2build documentation has more details about these
+ optional features.
+
+ The first argument for pcre2_config() specifies which information is
+ required. The second argument is a pointer to memory into which the
+ information is placed. If NULL is passed, the function returns the
+ amount of memory that is needed for the requested information. For
+ calls that return numerical values, the value is in bytes; when
+ requesting these values, where should point to appropriately aligned
+ memory. For calls that return strings, the required length is given in
+ code units, not counting the terminating zero.
+
+ When requesting information, the returned value from pcre2_config() is
+ non-negative on success, or the negative error code PCRE2_ERROR_BADOP-
+ TION if the value in the first argument is not recognized. The follow-
+ ing information is available:
+
+ PCRE2_CONFIG_BSR
+
+ The output is a uint32_t integer whose value indicates what character
+ sequences the \R escape sequence matches by default. A value of
+ PCRE2_BSR_UNICODE means that \R matches any Unicode line ending
+ sequence; a value of PCRE2_BSR_ANYCRLF means that \R matches only CR,
+ LF, or CRLF. The default can be overridden when a pattern is compiled.
+
+ PCRE2_CONFIG_JIT
+
+ The output is a uint32_t integer that is set to one if support for
+ just-in-time compiling is available; otherwise it is set to zero.
+
+ PCRE2_CONFIG_JITTARGET
+
+ The where argument should point to a buffer that is at least 48 code
+ units long. (The exact length required can be found by calling
+ pcre2_config() with where set to NULL.) The buffer is filled with a
+ string that contains the name of the architecture for which the JIT
+ compiler is configured, for example "x86 32bit (little endian +
+ unaligned)". If JIT support is not available, PCRE2_ERROR_BADOPTION is
+ returned, otherwise the number of code units used is returned. This is
+ the length of the string, plus one unit for the terminating zero.
+
+ PCRE2_CONFIG_LINKSIZE
+
+ The output is a uint32_t integer that contains the number of bytes used
+ for internal linkage in compiled regular expressions. When PCRE2 is
+ configured, the value can be set to 2, 3, or 4, with the default being
+ 2. This is the value that is returned by pcre2_config(). However, when
+ the 16-bit library is compiled, a value of 3 is rounded up to 4, and
+ when the 32-bit library is compiled, internal linkages always use 4
+ bytes, so the configured value is not relevant.
+
+ The default value of 2 for the 8-bit and 16-bit libraries is sufficient
+ for all but the most massive patterns, since it allows the size of the
+ compiled pattern to be up to 64K code units. Larger values allow larger
+ regular expressions to be compiled by those two libraries, but at the
+ expense of slower matching.
+
+ PCRE2_CONFIG_MATCHLIMIT
+
+ The output is a uint32_t integer that gives the default limit for the
+ number of internal matching function calls in a pcre2_match() execu-
+ tion. Further details are given with pcre2_match() below.
+
+ PCRE2_CONFIG_NEWLINE
+
+ The output is a uint32_t integer whose value specifies the default
+ character sequence that is recognized as meaning "newline". The values
+ are:
+
+ PCRE2_NEWLINE_CR Carriage return (CR)
+ PCRE2_NEWLINE_LF Linefeed (LF)
+ PCRE2_NEWLINE_CRLF Carriage return, linefeed (CRLF)
+ PCRE2_NEWLINE_ANY Any Unicode line ending
+ PCRE2_NEWLINE_ANYCRLF Any of CR, LF, or CRLF
+
+ The default should normally correspond to the standard sequence for
+ your operating system.
+
+ PCRE2_CONFIG_PARENSLIMIT
+
+ The output is a uint32_t integer that gives the maximum depth of nest-
+ ing of parentheses (of any kind) in a pattern. This limit is imposed to
+ cap the amount of system stack used when a pattern is compiled. It is
+ specified when PCRE2 is built; the default is 250. This limit does not
+ take into account the stack that may already be used by the calling
+ application. For finer control over compilation stack usage, see
+ pcre2_set_compile_recursion_guard().
+
+ PCRE2_CONFIG_RECURSIONLIMIT
+
+ The output is a uint32_t integer that gives the default limit for the
+ depth of recursion when calling the internal matching function in a
+ pcre2_match() execution. Further details are given with pcre2_match()
+ below.
+
+ PCRE2_CONFIG_STACKRECURSE
+
+ The output is a uint32_t integer that is set to one if internal recur-
+ sion when running pcre2_match() is implemented by recursive function
+ calls that use the system stack to remember their state. This is the
+ usual way that PCRE2 is compiled. The output is zero if PCRE2 was com-
+ piled to use blocks of data on the heap instead of recursive function
+ calls.
+
+ PCRE2_CONFIG_UNICODE_VERSION
+
+ The where argument should point to a buffer that is at least 24 code
+ units long. (The exact length required can be found by calling
+ pcre2_config() with where set to NULL.) If PCRE2 has been compiled
+ without Unicode support, the buffer is filled with the text "Unicode
+ not supported". Otherwise, the Unicode version string (for example,
+ "8.0.0") is inserted. The number of code units used is returned. This
+ is the length of the string plus one unit for the terminating zero.
+
+ PCRE2_CONFIG_UNICODE
+
+ The output is a uint32_t integer that is set to one if Unicode support
+ is available; otherwise it is set to zero. Unicode support implies UTF
+ support.
+
+ PCRE2_CONFIG_VERSION
+
+ The where argument should point to a buffer that is at least 12 code
+ units long. (The exact length required can be found by calling
+ pcre2_config() with where set to NULL.) The buffer is filled with the
+ PCRE2 version string, zero-terminated. The number of code units used is
+ returned. This is the length of the string plus one unit for the termi-
+ nating zero.
+
+
+COMPILING A PATTERN
+
+ pcre2_code *pcre2_compile(PCRE2_SPTR pattern, PCRE2_SIZE length,
+ uint32_t options, int *errorcode, PCRE2_SIZE *erroroffset,
+ pcre2_compile_context *ccontext);
+
+ void pcre2_code_free(pcre2_code *code);
+
+ The pcre2_compile() function compiles a pattern into an internal form.
+ The pattern is defined by a pointer to a string of code units and a
+ length, If the pattern is zero-terminated, the length can be specified
+ as PCRE2_ZERO_TERMINATED. The function returns a pointer to a block of
+ memory that contains the compiled pattern and related data. The caller
+ must free the memory by calling pcre2_code_free() when it is no longer
+ needed.
+
+ NOTE: When one of the matching functions is called, pointers to the
+ compiled pattern and the subject string are set in the match data block
+ so that they can be referenced by the extraction functions. After run-
+ ning a match, you must not free a compiled pattern (or a subject
+ string) until after all operations on the match data block have taken
+ place.
+
+ If the compile context argument ccontext is NULL, memory for the com-
+ piled pattern is obtained by calling malloc(). Otherwise, it is
+ obtained from the same memory function that was used for the compile
+ context.
+
+ The options argument contains various bit settings that affect the com-
+ pilation. It should be zero if no options are required. The available
+ options are described below. Some of them (in particular, those that
+ are compatible with Perl, but some others as well) can also be set and
+ unset from within the pattern (see the detailed description in the
+ pcre2pattern documentation).
+
+ For those options that can be different in different parts of the pat-
+ tern, the contents of the options argument specifies their settings at
+ the start of compilation. The PCRE2_ANCHORED and PCRE2_NO_UTF_CHECK
+ options can be set at the time of matching as well as at compile time.
+
+ Other, less frequently required compile-time parameters (for example,
+ the newline setting) can be provided in a compile context (as described
+ above).
+
+ If errorcode or erroroffset is NULL, pcre2_compile() returns NULL imme-
+ diately. Otherwise, if compilation of a pattern fails, pcre2_compile()
+ returns NULL, having set these variables to an error code and an offset
+ (number of code units) within the pattern, respectively. The
+ pcre2_get_error_message() function provides a textual message for each
+ error code. Compilation errors are positive numbers, but UTF formatting
+ errors are negative numbers. For an invalid UTF-8 or UTF-16 string, the
+ offset is that of the first code unit of the failing character.
+
+ Some errors are not detected until the whole pattern has been scanned;
+ in these cases, the offset passed back is the length of the pattern.
+ Note that the offset is in code units, not characters, even in a UTF
+ mode. It may sometimes point into the middle of a UTF-8 or UTF-16 char-
+ acter.
+
+ This code fragment shows a typical straightforward call to pcre2_com-
+ pile():
+
+ pcre2_code *re;
+ PCRE2_SIZE erroffset;
+ int errorcode;
+ re = pcre2_compile(
+ "^A.*Z", /* the pattern */
+ PCRE2_ZERO_TERMINATED, /* the pattern is zero-terminated */
+ 0, /* default options */
+ &errorcode, /* for error code */
+ &erroffset, /* for error offset */
+ NULL); /* no compile context */
+
+ The following names for option bits are defined in the pcre2.h header
+ file:
+
+ PCRE2_ANCHORED
+
+ If this bit is set, the pattern is forced to be "anchored", that is, it
+ is constrained to match only at the first matching point in the string
+ that is being searched (the "subject string"). This effect can also be
+ achieved by appropriate constructs in the pattern itself, which is the
+ only way to do it in Perl.
+
+ PCRE2_ALLOW_EMPTY_CLASS
+
+ By default, for compatibility with Perl, a closing square bracket that
+ immediately follows an opening one is treated as a data character for
+ the class. When PCRE2_ALLOW_EMPTY_CLASS is set, it terminates the
+ class, which therefore contains no characters and so can never match.
+
+ PCRE2_ALT_BSUX
+
+ This option request alternative handling of three escape sequences,
+ which makes PCRE2's behaviour more like ECMAscript (aka JavaScript).
+ When it is set:
+
+ (1) \U matches an upper case "U" character; by default \U causes a com-
+ pile time error (Perl uses \U to upper case subsequent characters).
+
+ (2) \u matches a lower case "u" character unless it is followed by four
+ hexadecimal digits, in which case the hexadecimal number defines the
+ code point to match. By default, \u causes a compile time error (Perl
+ uses it to upper case the following character).
+
+ (3) \x matches a lower case "x" character unless it is followed by two
+ hexadecimal digits, in which case the hexadecimal number defines the
+ code point to match. By default, as in Perl, a hexadecimal number is
+ always expected after \x, but it may have zero, one, or two digits (so,
+ for example, \xz matches a binary zero character followed by z).
+
+ PCRE2_ALT_CIRCUMFLEX
+
+ In multiline mode (when PCRE2_MULTILINE is set), the circumflex
+ metacharacter matches at the start of the subject (unless PCRE2_NOTBOL
+ is set), and also after any internal newline. However, it does not
+ match after a newline at the end of the subject, for compatibility with
+ Perl. If you want a multiline circumflex also to match after a termi-
+ nating newline, you must set PCRE2_ALT_CIRCUMFLEX.
+
+ PCRE2_ALT_VERBNAMES
+
+ By default, for compatibility with Perl, the name in any verb sequence
+ such as (*MARK:NAME) is any sequence of characters that does not
+ include a closing parenthesis. The name is not processed in any way,
+ and it is not possible to include a closing parenthesis in the name.
+ However, if the PCRE2_ALT_VERBNAMES option is set, normal backslash
+ processing is applied to verb names and only an unescaped closing
+ parenthesis terminates the name. A closing parenthesis can be included
+ in a name either as \) or between \Q and \E. If the PCRE2_EXTENDED
+ option is set, unescaped whitespace in verb names is skipped and #-com-
+ ments are recognized, exactly as in the rest of the pattern.
+
+ PCRE2_AUTO_CALLOUT
+
+ If this bit is set, pcre2_compile() automatically inserts callout
+ items, all with number 255, before each pattern item. For discussion of
+ the callout facility, see the pcre2callout documentation.
+
+ PCRE2_CASELESS
+
+ If this bit is set, letters in the pattern match both upper and lower
+ case letters in the subject. It is equivalent to Perl's /i option, and
+ it can be changed within a pattern by a (?i) option setting.
+
+ PCRE2_DOLLAR_ENDONLY
+
+ If this bit is set, a dollar metacharacter in the pattern matches only
+ at the end of the subject string. Without this option, a dollar also
+ matches immediately before a newline at the end of the string (but not
+ before any other newlines). The PCRE2_DOLLAR_ENDONLY option is ignored
+ if PCRE2_MULTILINE is set. There is no equivalent to this option in
+ Perl, and no way to set it within a pattern.
+
+ PCRE2_DOTALL
+
+ If this bit is set, a dot metacharacter in the pattern matches any
+ character, including one that indicates a newline. However, it only
+ ever matches one character, even if newlines are coded as CRLF. Without
+ this option, a dot does not match when the current position in the sub-
+ ject is at a newline. This option is equivalent to Perl's /s option,
+ and it can be changed within a pattern by a (?s) option setting. A neg-
+ ative class such as [^a] always matches newline characters, independent
+ of the setting of this option.
+
+ PCRE2_DUPNAMES
+
+ If this bit is set, names used to identify capturing subpatterns need
+ not be unique. This can be helpful for certain types of pattern when it
+ is known that only one instance of the named subpattern can ever be
+ matched. There are more details of named subpatterns below; see also
+ the pcre2pattern documentation.
+
+ PCRE2_EXTENDED
+
+ If this bit is set, most white space characters in the pattern are
+ totally ignored except when escaped or inside a character class. How-
+ ever, white space is not allowed within sequences such as (?> that
+ introduce various parenthesized subpatterns, nor within numerical quan-
+ tifiers such as {1,3}. Ignorable white space is permitted between an
+ item and a following quantifier and between a quantifier and a follow-
+ ing + that indicates possessiveness.
+
+ PCRE2_EXTENDED also causes characters between an unescaped # outside a
+ character class and the next newline, inclusive, to be ignored, which
+ makes it possible to include comments inside complicated patterns. Note
+ that the end of this type of comment is a literal newline sequence in
+ the pattern; escape sequences that happen to represent a newline do not
+ count. PCRE2_EXTENDED is equivalent to Perl's /x option, and it can be
+ changed within a pattern by a (?x) option setting.
+
+ Which characters are interpreted as newlines can be specified by a set-
+ ting in the compile context that is passed to pcre2_compile() or by a
+ special sequence at the start of the pattern, as described in the sec-
+ tion entitled "Newline conventions" in the pcre2pattern documentation.
+ A default is defined when PCRE2 is built.
+
+ PCRE2_FIRSTLINE
+
+ If this option is set, an unanchored pattern is required to match
+ before or at the first newline in the subject string, though the
+ matched text may continue over the newline. See also PCRE2_USE_OFF-
+ SET_LIMIT, which provides a more general limiting facility. If
+ PCRE2_FIRSTLINE is set with an offset limit, a match must occur in the
+ first line and also within the offset limit. In other words, whichever
+ limit comes first is used.
+
+ PCRE2_MATCH_UNSET_BACKREF
+
+ If this option is set, a back reference to an unset subpattern group
+ matches an empty string (by default this causes the current matching
+ alternative to fail). A pattern such as (\1)(a) succeeds when this
+ option is set (assuming it can find an "a" in the subject), whereas it
+ fails by default, for Perl compatibility. Setting this option makes
+ PCRE2 behave more like ECMAscript (aka JavaScript).
+
+ PCRE2_MULTILINE
+
+ By default, for the purposes of matching "start of line" and "end of
+ line", PCRE2 treats the subject string as consisting of a single line
+ of characters, even if it actually contains newlines. The "start of
+ line" metacharacter (^) matches only at the start of the string, and
+ the "end of line" metacharacter ($) matches only at the end of the
+ string, or before a terminating newline (except when PCRE2_DOL-
+ LAR_ENDONLY is set). Note, however, that unless PCRE2_DOTALL is set,
+ the "any character" metacharacter (.) does not match at a newline. This
+ behaviour (for ^, $, and dot) is the same as Perl.
+
+ When PCRE2_MULTILINE it is set, the "start of line" and "end of line"
+ constructs match immediately following or immediately before internal
+ newlines in the subject string, respectively, as well as at the very
+ start and end. This is equivalent to Perl's /m option, and it can be
+ changed within a pattern by a (?m) option setting. Note that the "start
+ of line" metacharacter does not match after a newline at the end of the
+ subject, for compatibility with Perl. However, you can change this by
+ setting the PCRE2_ALT_CIRCUMFLEX option. If there are no newlines in a
+ subject string, or no occurrences of ^ or $ in a pattern, setting
+ PCRE2_MULTILINE has no effect.
+
+ PCRE2_NEVER_BACKSLASH_C
+
+ This option locks out the use of \C in the pattern that is being com-
+ piled. This escape can cause unpredictable behaviour in UTF-8 or
+ UTF-16 modes, because it may leave the current matching point in the
+ middle of a multi-code-unit character. This option may be useful in
+ applications that process patterns from external sources. Note that
+ there is also a build-time option that permanently locks out the use of
+ \C.
+
+ PCRE2_NEVER_UCP
+
+ This option locks out the use of Unicode properties for handling \B,
+ \b, \D, \d, \S, \s, \W, \w, and some of the POSIX character classes, as
+ described for the PCRE2_UCP option below. In particular, it prevents
+ the creator of the pattern from enabling this facility by starting the
+ pattern with (*UCP). This option may be useful in applications that
+ process patterns from external sources. The option combination PCRE_UCP
+ and PCRE_NEVER_UCP causes an error.
+
+ PCRE2_NEVER_UTF
+
+ This option locks out interpretation of the pattern as UTF-8, UTF-16,
+ or UTF-32, depending on which library is in use. In particular, it pre-
+ vents the creator of the pattern from switching to UTF interpretation
+ by starting the pattern with (*UTF). This option may be useful in
+ applications that process patterns from external sources. The combina-
+ tion of PCRE2_UTF and PCRE2_NEVER_UTF causes an error.
+
+ PCRE2_NO_AUTO_CAPTURE
+
+ If this option is set, it disables the use of numbered capturing paren-
+ theses in the pattern. Any opening parenthesis that is not followed by
+ ? behaves as if it were followed by ?: but named parentheses can still
+ be used for capturing (and they acquire numbers in the usual way).
+ There is no equivalent of this option in Perl.
+
+ PCRE2_NO_AUTO_POSSESS
+
+ If this option is set, it disables "auto-possessification", which is an
+ optimization that, for example, turns a+b into a++b in order to avoid
+ backtracks into a+ that can never be successful. However, if callouts
+ are in use, auto-possessification means that some callouts are never
+ taken. You can set this option if you want the matching functions to do
+ a full unoptimized search and run all the callouts, but it is mainly
+ provided for testing purposes.
+
+ PCRE2_NO_DOTSTAR_ANCHOR
+
+ If this option is set, it disables an optimization that is applied when
+ .* is the first significant item in a top-level branch of a pattern,
+ and all the other branches also start with .* or with \A or \G or ^.
+ The optimization is automatically disabled for .* if it is inside an
+ atomic group or a capturing group that is the subject of a back refer-
+ ence, or if the pattern contains (*PRUNE) or (*SKIP). When the opti-
+ mization is not disabled, such a pattern is automatically anchored if
+ PCRE2_DOTALL is set for all the .* items and PCRE2_MULTILINE is not set
+ for any ^ items. Otherwise, the fact that any match must start either
+ at the start of the subject or following a newline is remembered. Like
+ other optimizations, this can cause callouts to be skipped.
+
+ PCRE2_NO_START_OPTIMIZE
+
+ This is an option whose main effect is at matching time. It does not
+ change what pcre2_compile() generates, but it does affect the output of
+ the JIT compiler.
+
+ There are a number of optimizations that may occur at the start of a
+ match, in order to speed up the process. For example, if it is known
+ that an unanchored match must start with a specific character, the
+ matching code searches the subject for that character, and fails imme-
+ diately if it cannot find it, without actually running the main match-
+ ing function. This means that a special item such as (*COMMIT) at the
+ start of a pattern is not considered until after a suitable starting
+ point for the match has been found. Also, when callouts or (*MARK)
+ items are in use, these "start-up" optimizations can cause them to be
+ skipped if the pattern is never actually used. The start-up optimiza-
+ tions are in effect a pre-scan of the subject that takes place before
+ the pattern is run.
+
+ The PCRE2_NO_START_OPTIMIZE option disables the start-up optimizations,
+ possibly causing performance to suffer, but ensuring that in cases
+ where the result is "no match", the callouts do occur, and that items
+ such as (*COMMIT) and (*MARK) are considered at every possible starting
+ position in the subject string.
+
+ Setting PCRE2_NO_START_OPTIMIZE may change the outcome of a matching
+ operation. Consider the pattern
+
+ (*COMMIT)ABC
+
+ When this is compiled, PCRE2 records the fact that a match must start
+ with the character "A". Suppose the subject string is "DEFABC". The
+ start-up optimization scans along the subject, finds "A" and runs the
+ first match attempt from there. The (*COMMIT) item means that the pat-
+ tern must match the current starting position, which in this case, it
+ does. However, if the same match is run with PCRE2_NO_START_OPTIMIZE
+ set, the initial scan along the subject string does not happen. The
+ first match attempt is run starting from "D" and when this fails,
+ (*COMMIT) prevents any further matches being tried, so the overall
+ result is "no match". There are also other start-up optimizations. For
+ example, a minimum length for the subject may be recorded. Consider the
+ pattern
+
+ (*MARK:A)(X|Y)
+
+ The minimum length for a match is one character. If the subject is
+ "ABC", there will be attempts to match "ABC", "BC", and "C". An attempt
+ to match an empty string at the end of the subject does not take place,
+ because PCRE2 knows that the subject is now too short, and so the
+ (*MARK) is never encountered. In this case, the optimization does not
+ affect the overall match result, which is still "no match", but it does
+ affect the auxiliary information that is returned.
+
+ PCRE2_NO_UTF_CHECK
+
+ When PCRE2_UTF is set, the validity of the pattern as a UTF string is
+ automatically checked. There are discussions about the validity of
+ UTF-8 strings, UTF-16 strings, and UTF-32 strings in the pcre2unicode
+ document. If an invalid UTF sequence is found, pcre2_compile() returns
+ a negative error code.
+
+ If you know that your pattern is valid, and you want to skip this check
+ for performance reasons, you can set the PCRE2_NO_UTF_CHECK option.
+ When it is set, the effect of passing an invalid UTF string as a pat-
+ tern is undefined. It may cause your program to crash or loop. Note
+ that this option can also be passed to pcre2_match() and
+ pcre_dfa_match(), to suppress validity checking of the subject string.
+
+ PCRE2_UCP
+
+ This option changes the way PCRE2 processes \B, \b, \D, \d, \S, \s, \W,
+ \w, and some of the POSIX character classes. By default, only ASCII
+ characters are recognized, but if PCRE2_UCP is set, Unicode properties
+ are used instead to classify characters. More details are given in the
+ section on generic character types in the pcre2pattern page. If you set
+ PCRE2_UCP, matching one of the items it affects takes much longer. The
+ option is available only if PCRE2 has been compiled with Unicode sup-
+ port.
+
+ PCRE2_UNGREEDY
+
+ This option inverts the "greediness" of the quantifiers so that they
+ are not greedy by default, but become greedy if followed by "?". It is
+ not compatible with Perl. It can also be set by a (?U) option setting
+ within the pattern.
+
+ PCRE2_USE_OFFSET_LIMIT
+
+ This option must be set for pcre2_compile() if pcre2_set_offset_limit()
+ is going to be used to set a non-default offset limit in a match con-
+ text for matches that use this pattern. An error is generated if an
+ offset limit is set without this option. For more details, see the
+ description of pcre2_set_offset_limit() in the section that describes
+ match contexts. See also the PCRE2_FIRSTLINE option above.
+
+ PCRE2_UTF
+
+ This option causes PCRE2 to regard both the pattern and the subject
+ strings that are subsequently processed as strings of UTF characters
+ instead of single-code-unit strings. It is available when PCRE2 is
+ built to include Unicode support (which is the default). If Unicode
+ support is not available, the use of this option provokes an error.
+ Details of how this option changes the behaviour of PCRE2 are given in
+ the pcre2unicode page.
+
+
+COMPILATION ERROR CODES
+
+ There are over 80 positive error codes that pcre2_compile() may return
+ if it finds an error in the pattern. There are also some negative error
+ codes that are used for invalid UTF strings. These are the same as
+ given by pcre2_match() and pcre2_dfa_match(), and are described in the
+ pcre2unicode page. The pcre2_get_error_message() function can be called
+ to obtain a textual error message from any error code.
+
+
+JUST-IN-TIME (JIT) COMPILATION
+
+ int pcre2_jit_compile(pcre2_code *code, uint32_t options);
+
+ int pcre2_jit_match(const pcre2_code *code, PCRE2_SPTR subject,
+ PCRE2_SIZE length, PCRE2_SIZE startoffset,
+ uint32_t options, pcre2_match_data *match_data,
+ pcre2_match_context *mcontext);
+
+ void pcre2_jit_free_unused_memory(pcre2_general_context *gcontext);
+
+ pcre2_jit_stack *pcre2_jit_stack_create(PCRE2_SIZE startsize,
+ PCRE2_SIZE maxsize, pcre2_general_context *gcontext);
+
+ void pcre2_jit_stack_assign(pcre2_match_context *mcontext,
+ pcre2_jit_callback callback_function, void *callback_data);
+
+ void pcre2_jit_stack_free(pcre2_jit_stack *jit_stack);
+
+ These functions provide support for JIT compilation, which, if the
+ just-in-time compiler is available, further processes a compiled pat-
+ tern into machine code that executes much faster than the pcre2_match()
+ interpretive matching function. Full details are given in the pcre2jit
+ documentation.
+
+ JIT compilation is a heavyweight optimization. It can take some time
+ for patterns to be analyzed, and for one-off matches and simple pat-
+ terns the benefit of faster execution might be offset by a much slower
+ compilation time. Most, but not all patterns can be optimized by the
+ JIT compiler.
+
+
+LOCALE SUPPORT
+
+ PCRE2 handles caseless matching, and determines whether characters are
+ letters, digits, or whatever, by reference to a set of tables, indexed
+ by character code point. This applies only to characters whose code
+ points are less than 256. By default, higher-valued code points never
+ match escapes such as \w or \d. However, if PCRE2 is built with UTF
+ support, all characters can be tested with \p and \P, or, alterna-
+ tively, the PCRE2_UCP option can be set when a pattern is compiled;
+ this causes \w and friends to use Unicode property support instead of
+ the built-in tables.
+
+ The use of locales with Unicode is discouraged. If you are handling
+ characters with code points greater than 128, you should either use
+ Unicode support, or use locales, but not try to mix the two.
+
+ PCRE2 contains an internal set of character tables that are used by
+ default. These are sufficient for many applications. Normally, the
+ internal tables recognize only ASCII characters. However, when PCRE2 is
+ built, it is possible to cause the internal tables to be rebuilt in the
+ default "C" locale of the local system, which may cause them to be dif-
+ ferent.
+
+ The internal tables can be overridden by tables supplied by the appli-
+ cation that calls PCRE2. These may be created in a different locale
+ from the default. As more and more applications change to using Uni-
+ code, the need for this locale support is expected to die away.
+
+ External tables are built by calling the pcre2_maketables() function,
+ in the relevant locale. The result can be passed to pcre2_compile() as
+ often as necessary, by creating a compile context and calling
+ pcre2_set_character_tables() to set the tables pointer therein. For
+ example, to build and use tables that are appropriate for the French
+ locale (where accented characters with values greater than 128 are
+ treated as letters), the following code could be used:
+
+ setlocale(LC_CTYPE, "fr_FR");
+ tables = pcre2_maketables(NULL);
+ ccontext = pcre2_compile_context_create(NULL);
+ pcre2_set_character_tables(ccontext, tables);
+ re = pcre2_compile(..., ccontext);
+
+ The locale name "fr_FR" is used on Linux and other Unix-like systems;
+ if you are using Windows, the name for the French locale is "french".
+ It is the caller's responsibility to ensure that the memory containing
+ the tables remains available for as long as it is needed.
+
+ The pointer that is passed (via the compile context) to pcre2_compile()
+ is saved with the compiled pattern, and the same tables are used by
+ pcre2_match() and pcre_dfa_match(). Thus, for any single pattern, com-
+ pilation, and matching all happen in the same locale, but different
+ patterns can be processed in different locales.
+
+
+INFORMATION ABOUT A COMPILED PATTERN
+
+ int pcre2_pattern_info(const pcre2 *code, uint32_t what, void *where);
+
+ The pcre2_pattern_info() function returns general information about a
+ compiled pattern. For information about callouts, see the next section.
+ The first argument for pcre2_pattern_info() is a pointer to the com-
+ piled pattern. The second argument specifies which piece of information
+ is required, and the third argument is a pointer to a variable to
+ receive the data. If the third argument is NULL, the first argument is
+ ignored, and the function returns the size in bytes of the variable
+ that is required for the information requested. Otherwise, The yield of
+ the function is zero for success, or one of the following negative num-
+ bers:
+
+ PCRE2_ERROR_NULL the argument code was NULL
+ PCRE2_ERROR_BADMAGIC the "magic number" was not found
+ PCRE2_ERROR_BADOPTION the value of what was invalid
+ PCRE2_ERROR_UNSET the requested field is not set
+
+ The "magic number" is placed at the start of each compiled pattern as
+ an simple check against passing an arbitrary memory pointer. Here is a
+ typical call of pcre2_pattern_info(), to obtain the length of the com-
+ piled pattern:
+
+ int rc;
+ size_t length;
+ rc = pcre2_pattern_info(
+ re, /* result of pcre2_compile() */
+ PCRE2_INFO_SIZE, /* what is required */
+ &length); /* where to put the data */
+
+ The possible values for the second argument are defined in pcre2.h, and
+ are as follows:
+
+ PCRE2_INFO_ALLOPTIONS
+ PCRE2_INFO_ARGOPTIONS
+
+ Return a copy of the pattern's options. The third argument should point
+ to a uint32_t variable. PCRE2_INFO_ARGOPTIONS returns exactly the
+ options that were passed to pcre2_compile(), whereas PCRE2_INFO_ALLOP-
+ TIONS returns the compile options as modified by any top-level option
+ settings such as (*UTF) at the start of the pattern itself. For exam-
+ ple, if the pattern /(*UTF)abc/ is compiled with the PCRE2_EXTENDED
+ option, the result is PCRE2_EXTENDED and PCRE2_UTF.
+
+ A pattern compiled without PCRE2_ANCHORED is automatically anchored by
+ PCRE2 if the first significant item in every top-level branch is one of
+ the following:
+
+ ^ unless PCRE2_MULTILINE is set
+ \A always
+ \G always
+ .* sometimes - see below
+
+ When .* is the first significant item, anchoring is possible only when
+ all the following are true:
+
+ .* is not in an atomic group
+ .* is not in a capturing group that is the subject
+ of a back reference
+ PCRE2_DOTALL is in force for .*
+ Neither (*PRUNE) nor (*SKIP) appears in the pattern.
+ PCRE2_NO_DOTSTAR_ANCHOR is not set.
+
+ For patterns that are auto-anchored, the PCRE2_ANCHORED bit is set in
+ the options returned for PCRE2_INFO_ALLOPTIONS.
+
+ PCRE2_INFO_BACKREFMAX
+
+ Return the number of the highest back reference in the pattern. The
+ third argument should point to an uint32_t variable. Named subpatterns
+ acquire numbers as well as names, and these count towards the highest
+ back reference. Back references such as \4 or \g{12} match the cap-
+ tured characters of the given group, but in addition, the check that a
+ capturing group is set in a conditional subpattern such as (?(3)a|b) is
+ also a back reference. Zero is returned if there are no back refer-
+ ences.
+
+ PCRE2_INFO_BSR
+
+ The output is a uint32_t whose value indicates what character sequences
+ the \R escape sequence matches. A value of PCRE2_BSR_UNICODE means that
+ \R matches any Unicode line ending sequence; a value of PCRE2_BSR_ANY-
+ CRLF means that \R matches only CR, LF, or CRLF.
+
+ PCRE2_INFO_CAPTURECOUNT
+
+ Return the highest capturing subpattern number in the pattern. In pat-
+ terns where (?| is not used, this is also the total number of capturing
+ subpatterns. The third argument should point to an uint32_t variable.
+
+ PCRE2_INFO_FIRSTBITMAP
+
+ In the absence of a single first code unit for a non-anchored pattern,
+ pcre2_compile() may construct a 256-bit table that defines a fixed set
+ of values for the first code unit in any match. For example, a pattern
+ that starts with [abc] results in a table with three bits set. When
+ code unit values greater than 255 are supported, the flag bit for 255
+ means "any code unit of value 255 or above". If such a table was con-
+ structed, a pointer to it is returned. Otherwise NULL is returned. The
+ third argument should point to an const uint8_t * variable.
+
+ PCRE2_INFO_FIRSTCODETYPE
+
+ Return information about the first code unit of any matched string, for
+ a non-anchored pattern. The third argument should point to an uint32_t
+ variable. If there is a fixed first value, for example, the letter "c"
+ from a pattern such as (cat|cow|coyote), 1 is returned, and the charac-
+ ter value can be retrieved using PCRE2_INFO_FIRSTCODEUNIT. If there is
+ no fixed first value, but it is known that a match can occur only at
+ the start of the subject or following a newline in the subject, 2 is
+ returned. Otherwise, and for anchored patterns, 0 is returned.
+
+ PCRE2_INFO_FIRSTCODEUNIT
+
+ Return the value of the first code unit of any matched string in the
+ situation where PCRE2_INFO_FIRSTCODETYPE returns 1; otherwise return 0.
+ The third argument should point to an uint32_t variable. In the 8-bit
+ library, the value is always less than 256. In the 16-bit library the
+ value can be up to 0xffff. In the 32-bit library in UTF-32 mode the
+ value can be up to 0x10ffff, and up to 0xffffffff when not using UTF-32
+ mode.
+
+ PCRE2_INFO_HASBACKSLASHC
+
+ Return 1 if the pattern contains any instances of \C, otherwise 0. The
+ third argument should point to an uint32_t variable.
+
+ PCRE2_INFO_HASCRORLF
+
+ Return 1 if the pattern contains any explicit matches for CR or LF
+ characters, otherwise 0. The third argument should point to an uint32_t
+ variable. An explicit match is either a literal CR or LF character, or
+ \r or \n.
+
+ PCRE2_INFO_JCHANGED
+
+ Return 1 if the (?J) or (?-J) option setting is used in the pattern,
+ otherwise 0. The third argument should point to an uint32_t variable.
+ (?J) and (?-J) set and unset the local PCRE2_DUPNAMES option, respec-
+ tively.
+
+ PCRE2_INFO_JITSIZE
+
+ If the compiled pattern was successfully processed by pcre2_jit_com-
+ pile(), return the size of the JIT compiled code, otherwise return
+ zero. The third argument should point to a size_t variable.
+
+ PCRE2_INFO_LASTCODETYPE
+
+ Returns 1 if there is a rightmost literal code unit that must exist in
+ any matched string, other than at its start. The third argument should
+ point to an uint32_t variable. If there is no such value, 0 is
+ returned. When 1 is returned, the code unit value itself can be
+ retrieved using PCRE2_INFO_LASTCODEUNIT. For anchored patterns, a last
+ literal value is recorded only if it follows something of variable
+ length. For example, for the pattern /^a\d+z\d+/ the returned value is
+ 1 (with "z" returned from PCRE2_INFO_LASTCODEUNIT), but for /^a\dz\d/
+ the returned value is 0.
+
+ PCRE2_INFO_LASTCODEUNIT
+
+ Return the value of the rightmost literal data unit that must exist in
+ any matched string, other than at its start, if such a value has been
+ recorded. The third argument should point to an uint32_t variable. If
+ there is no such value, 0 is returned.
+
+ PCRE2_INFO_MATCHEMPTY
+
+ Return 1 if the pattern might match an empty string, otherwise 0. The
+ third argument should point to an uint32_t variable. When a pattern
+ contains recursive subroutine calls it is not always possible to deter-
+ mine whether or not it can match an empty string. PCRE2 takes a cau-
+ tious approach and returns 1 in such cases.
+
+ PCRE2_INFO_MATCHLIMIT
+
+ If the pattern set a match limit by including an item of the form
+ (*LIMIT_MATCH=nnnn) at the start, the value is returned. The third
+ argument should point to an unsigned 32-bit integer. If no such value
+ has been set, the call to pcre2_pattern_info() returns the error
+ PCRE2_ERROR_UNSET.
+
+ PCRE2_INFO_MAXLOOKBEHIND
+
+ Return the number of characters (not code units) in the longest lookbe-
+ hind assertion in the pattern. The third argument should point to an
+ unsigned 32-bit integer. This information is useful when doing multi-
+ segment matching using the partial matching facilities. Note that the
+ simple assertions \b and \B require a one-character lookbehind. \A also
+ registers a one-character lookbehind, though it does not actually
+ inspect the previous character. This is to ensure that at least one
+ character from the old segment is retained when a new segment is pro-
+ cessed. Otherwise, if there are no lookbehinds in the pattern, \A might
+ match incorrectly at the start of a new segment.
+
+ PCRE2_INFO_MINLENGTH
+
+ If a minimum length for matching subject strings was computed, its
+ value is returned. Otherwise the returned value is 0. The value is a
+ number of characters, which in UTF mode may be different from the num-
+ ber of code units. The third argument should point to an uint32_t
+ variable. The value is a lower bound to the length of any matching
+ string. There may not be any strings of that length that do actually
+ match, but every string that does match is at least that long.
+
+ PCRE2_INFO_NAMECOUNT
+ PCRE2_INFO_NAMEENTRYSIZE
+ PCRE2_INFO_NAMETABLE
+
+ PCRE2 supports the use of named as well as numbered capturing parenthe-
+ ses. The names are just an additional way of identifying the parenthe-
+ ses, which still acquire numbers. Several convenience functions such as
+ pcre2_substring_get_byname() are provided for extracting captured sub-
+ strings by name. It is also possible to extract the data directly, by
+ first converting the name to a number in order to access the correct
+ pointers in the output vector (described with pcre2_match() below). To
+ do the conversion, you need to use the name-to-number map, which is
+ described by these three values.
+
+ The map consists of a number of fixed-size entries. PCRE2_INFO_NAME-
+ COUNT gives the number of entries, and PCRE2_INFO_NAMEENTRYSIZE gives
+ the size of each entry in code units; both of these return a uint32_t
+ value. The entry size depends on the length of the longest name.
+
+ PCRE2_INFO_NAMETABLE returns a pointer to the first entry of the table.
+ This is a PCRE2_SPTR pointer to a block of code units. In the 8-bit
+ library, the first two bytes of each entry are the number of the cap-
+ turing parenthesis, most significant byte first. In the 16-bit library,
+ the pointer points to 16-bit code units, the first of which contains
+ the parenthesis number. In the 32-bit library, the pointer points to
+ 32-bit code units, the first of which contains the parenthesis number.
+ The rest of the entry is the corresponding name, zero terminated.
+
+ The names are in alphabetical order. If (?| is used to create multiple
+ groups with the same number, as described in the section on duplicate
+ subpattern numbers in the pcre2pattern page, the groups may be given
+ the same name, but there is only one entry in the table. Different
+ names for groups of the same number are not permitted.
+
+ Duplicate names for subpatterns with different numbers are permitted,
+ but only if PCRE2_DUPNAMES is set. They appear in the table in the
+ order in which they were found in the pattern. In the absence of (?|
+ this is the order of increasing number; when (?| is used this is not
+ necessarily the case because later subpatterns may have lower numbers.
+
+ As a simple example of the name/number table, consider the following
+ pattern after compilation by the 8-bit library (assume PCRE2_EXTENDED
+ is set, so white space - including newlines - is ignored):
+
+ (?<date> (?<year>(\d\d)?\d\d) -
+ (?<month>\d\d) - (?<day>\d\d) )
+
+ There are four named subpatterns, so the table has four entries, and
+ each entry in the table is eight bytes long. The table is as follows,
+ with non-printing bytes shows in hexadecimal, and undefined bytes shown
+ as ??:
+
+ 00 01 d a t e 00 ??
+ 00 05 d a y 00 ?? ??
+ 00 04 m o n t h 00
+ 00 02 y e a r 00 ??
+
+ When writing code to extract data from named subpatterns using the
+ name-to-number map, remember that the length of the entries is likely
+ to be different for each compiled pattern.
+
+ PCRE2_INFO_NEWLINE
+
+ The output is a uint32_t with one of the following values:
+
+ PCRE2_NEWLINE_CR Carriage return (CR)
+ PCRE2_NEWLINE_LF Linefeed (LF)
+ PCRE2_NEWLINE_CRLF Carriage return, linefeed (CRLF)
+ PCRE2_NEWLINE_ANY Any Unicode line ending
+ PCRE2_NEWLINE_ANYCRLF Any of CR, LF, or CRLF
+
+ This specifies the default character sequence that will be recognized
+ as meaning "newline" while matching.
+
+ PCRE2_INFO_RECURSIONLIMIT
+
+ If the pattern set a recursion limit by including an item of the form
+ (*LIMIT_RECURSION=nnnn) at the start, the value is returned. The third
+ argument should point to an unsigned 32-bit integer. If no such value
+ has been set, the call to pcre2_pattern_info() returns the error
+ PCRE2_ERROR_UNSET.
+
+ PCRE2_INFO_SIZE
+
+ Return the size of the compiled pattern in bytes (for all three
+ libraries). The third argument should point to a size_t variable. This
+ value includes the size of the general data block that precedes the
+ code units of the compiled pattern itself. The value that is used when
+ pcre2_compile() is getting memory in which to place the compiled pat-
+ tern may be slightly larger than the value returned by this option,
+ because there are cases where the code that calculates the size has to
+ over-estimate. Processing a pattern with the JIT compiler does not
+ alter the value returned by this option.
+
+
+INFORMATION ABOUT A PATTERN'S CALLOUTS
+
+ int pcre2_callout_enumerate(const pcre2_code *code,
+ int (*callback)(pcre2_callout_enumerate_block *, void *),
+ void *user_data);
+
+ A script language that supports the use of string arguments in callouts
+ might like to scan all the callouts in a pattern before running the
+ match. This can be done by calling pcre2_callout_enumerate(). The first
+ argument is a pointer to a compiled pattern, the second points to a
+ callback function, and the third is arbitrary user data. The callback
+ function is called for every callout in the pattern in the order in
+ which they appear. Its first argument is a pointer to a callout enumer-
+ ation block, and its second argument is the user_data value that was
+ passed to pcre2_callout_enumerate(). The contents of the callout enu-
+ meration block are described in the pcre2callout documentation, which
+ also gives further details about callouts.
+
+
+SERIALIZATION AND PRECOMPILING
+
+ It is possible to save compiled patterns on disc or elsewhere, and
+ reload them later, subject to a number of restrictions. The functions
+ whose names begin with pcre2_serialize_ are used for this purpose. They
+ are described in the pcre2serialize documentation.
+
+
+THE MATCH DATA BLOCK
+
+ pcre2_match_data *pcre2_match_data_create(uint32_t ovecsize,
+ pcre2_general_context *gcontext);
+
+ pcre2_match_data *pcre2_match_data_create_from_pattern(
+ const pcre2_code *code, pcre2_general_context *gcontext);
+
+ void pcre2_match_data_free(pcre2_match_data *match_data);
+
+ Information about a successful or unsuccessful match is placed in a
+ match data block, which is an opaque structure that is accessed by
+ function calls. In particular, the match data block contains a vector
+ of offsets into the subject string that define the matched part of the
+ subject and any substrings that were captured. This is know as the
+ ovector.
+
+ Before calling pcre2_match(), pcre2_dfa_match(), or pcre2_jit_match()
+ you must create a match data block by calling one of the creation func-
+ tions above. For pcre2_match_data_create(), the first argument is the
+ number of pairs of offsets in the ovector. One pair of offsets is
+ required to identify the string that matched the whole pattern, with
+ another pair for each captured substring. For example, a value of 4
+ creates enough space to record the matched portion of the subject plus
+ three captured substrings. A minimum of at least 1 pair is imposed by
+ pcre2_match_data_create(), so it is always possible to return the over-
+ all matched string.
+
+ The second argument of pcre2_match_data_create() is a pointer to a gen-
+ eral context, which can specify custom memory management for obtaining
+ the memory for the match data block. If you are not using custom memory
+ management, pass NULL, which causes malloc() to be used.
+
+ For pcre2_match_data_create_from_pattern(), the first argument is a
+ pointer to a compiled pattern. The ovector is created to be exactly the
+ right size to hold all the substrings a pattern might capture. The sec-
+ ond argument is again a pointer to a general context, but in this case
+ if NULL is passed, the memory is obtained using the same allocator that
+ was used for the compiled pattern (custom or default).
+
+ A match data block can be used many times, with the same or different
+ compiled patterns. You can extract information from a match data block
+ after a match operation has finished, using functions that are
+ described in the sections on matched strings and other match data
+ below.
+
+ When a call of pcre2_match() fails, valid data is available in the
+ match block only when the error is PCRE2_ERROR_NOMATCH,
+ PCRE2_ERROR_PARTIAL, or one of the error codes for an invalid UTF
+ string. Exactly what is available depends on the error, and is detailed
+ below.
+
+ When one of the matching functions is called, pointers to the compiled
+ pattern and the subject string are set in the match data block so that
+ they can be referenced by the extraction functions. After running a
+ match, you must not free a compiled pattern or a subject string until
+ after all operations on the match data block (for that match) have
+ taken place.
+
+ When a match data block itself is no longer needed, it should be freed
+ by calling pcre2_match_data_free().
+
+
+MATCHING A PATTERN: THE TRADITIONAL FUNCTION
+
+ int pcre2_match(const pcre2_code *code, PCRE2_SPTR subject,
+ PCRE2_SIZE length, PCRE2_SIZE startoffset,
+ uint32_t options, pcre2_match_data *match_data,
+ pcre2_match_context *mcontext);
+
+ The function pcre2_match() is called to match a subject string against
+ a compiled pattern, which is passed in the code argument. You can call
+ pcre2_match() with the same code argument as many times as you like, in
+ order to find multiple matches in the subject string or to match dif-
+ ferent subject strings with the same pattern.
+
+ This function is the main matching facility of the library, and it
+ operates in a Perl-like manner. For specialist use there is also an
+ alternative matching function, which is described below in the section
+ about the pcre2_dfa_match() function.
+
+ Here is an example of a simple call to pcre2_match():
+
+ pcre2_match_data *md = pcre2_match_data_create(4, NULL);
+ int rc = pcre2_match(
+ re, /* result of pcre2_compile() */
+ "some string", /* the subject string */
+ 11, /* the length of the subject string */
+ 0, /* start at offset 0 in the subject */
+ 0, /* default options */
+ match_data, /* the match data block */
+ NULL); /* a match context; NULL means use defaults */
+
+ If the subject string is zero-terminated, the length can be given as
+ PCRE2_ZERO_TERMINATED. A match context must be provided if certain less
+ common matching parameters are to be changed. For details, see the sec-
+ tion on the match context above.
+
+ The string to be matched by pcre2_match()
+
+ The subject string is passed to pcre2_match() as a pointer in subject,
+ a length in length, and a starting offset in startoffset. The length
+ and offset are in code units, not characters. That is, they are in
+ bytes for the 8-bit library, 16-bit code units for the 16-bit library,
+ and 32-bit code units for the 32-bit library, whether or not UTF pro-
+ cessing is enabled.
+
+ If startoffset is greater than the length of the subject, pcre2_match()
+ returns PCRE2_ERROR_BADOFFSET. When the starting offset is zero, the
+ search for a match starts at the beginning of the subject, and this is
+ by far the most common case. In UTF-8 or UTF-16 mode, the starting off-
+ set must point to the start of a character, or to the end of the sub-
+ ject (in UTF-32 mode, one code unit equals one character, so all off-
+ sets are valid). Like the pattern string, the subject may contain
+ binary zeroes.
+
+ A non-zero starting offset is useful when searching for another match
+ in the same subject by calling pcre2_match() again after a previous
+ success. Setting startoffset differs from passing over a shortened
+ string and setting PCRE2_NOTBOL in the case of a pattern that begins
+ with any kind of lookbehind. For example, consider the pattern
+
+ \Biss\B
+
+ which finds occurrences of "iss" in the middle of words. (\B matches
+ only if the current position in the subject is not a word boundary.)
+ When applied to the string "Mississipi" the first call to pcre2_match()
+ finds the first occurrence. If pcre2_match() is called again with just
+ the remainder of the subject, namely "issipi", it does not match,
+ because \B is always false at the start of the subject, which is deemed
+ to be a word boundary. However, if pcre2_match() is passed the entire
+ string again, but with startoffset set to 4, it finds the second occur-
+ rence of "iss" because it is able to look behind the starting point to
+ discover that it is preceded by a letter.
+
+ Finding all the matches in a subject is tricky when the pattern can
+ match an empty string. It is possible to emulate Perl's /g behaviour by
+ first trying the match again at the same offset, with the
+ PCRE2_NOTEMPTY_ATSTART and PCRE2_ANCHORED options, and then if that
+ fails, advancing the starting offset and trying an ordinary match
+ again. There is some code that demonstrates how to do this in the
+ pcre2demo sample program. In the most general case, you have to check
+ to see if the newline convention recognizes CRLF as a newline, and if
+ so, and the current character is CR followed by LF, advance the start-
+ ing offset by two characters instead of one.
+
+ If a non-zero starting offset is passed when the pattern is anchored,
+ one attempt to match at the given offset is made. This can only succeed
+ if the pattern does not require the match to be at the start of the
+ subject.
+
+ Option bits for pcre2_match()
+
+ The unused bits of the options argument for pcre2_match() must be zero.
+ The only bits that may be set are PCRE2_ANCHORED, PCRE2_NOTBOL,
+ PCRE2_NOTEOL, PCRE2_NOTEMPTY, PCRE2_NOTEMPTY_ATSTART,
+ PCRE2_NO_UTF_CHECK, PCRE2_PARTIAL_HARD, and PCRE2_PARTIAL_SOFT. Their
+ action is described below.
+
+ Setting PCRE2_ANCHORED at match time is not supported by the just-in-
+ time (JIT) compiler. If it is set, JIT matching is disabled and the
+ normal interpretive code in pcre2_match() is run. The remaining options
+ are supported for JIT matching.
+
+ PCRE2_ANCHORED
+
+ The PCRE2_ANCHORED option limits pcre2_match() to matching at the first
+ matching position. If a pattern was compiled with PCRE2_ANCHORED, or
+ turned out to be anchored by virtue of its contents, it cannot be made
+ unachored at matching time. Note that setting the option at match time
+ disables JIT matching.
+
+ PCRE2_NOTBOL
+
+ This option specifies that first character of the subject string is not
+ the beginning of a line, so the circumflex metacharacter should not
+ match before it. Setting this without having set PCRE2_MULTILINE at
+ compile time causes circumflex never to match. This option affects only
+ the behaviour of the circumflex metacharacter. It does not affect \A.
+
+ PCRE2_NOTEOL
+
+ This option specifies that the end of the subject string is not the end
+ of a line, so the dollar metacharacter should not match it nor (except
+ in multiline mode) a newline immediately before it. Setting this with-
+ out having set PCRE2_MULTILINE at compile time causes dollar never to
+ match. This option affects only the behaviour of the dollar metacharac-
+ ter. It does not affect \Z or \z.
+
+ PCRE2_NOTEMPTY
+
+ An empty string is not considered to be a valid match if this option is
+ set. If there are alternatives in the pattern, they are tried. If all
+ the alternatives match the empty string, the entire match fails. For
+ example, if the pattern
+
+ a?b?
+
+ is applied to a string not beginning with "a" or "b", it matches an
+ empty string at the start of the subject. With PCRE2_NOTEMPTY set, this
+ match is not valid, so pcre2_match() searches further into the string
+ for occurrences of "a" or "b".
+
+ PCRE2_NOTEMPTY_ATSTART
+
+ This is like PCRE2_NOTEMPTY, except that it locks out an empty string
+ match only at the first matching position, that is, at the start of the
+ subject plus the starting offset. An empty string match later in the
+ subject is permitted. If the pattern is anchored, such a match can
+ occur only if the pattern contains \K.
+
+ PCRE2_NO_UTF_CHECK
+
+ When PCRE2_UTF is set at compile time, the validity of the subject as a
+ UTF string is checked by default when pcre2_match() is subsequently
+ called. If a non-zero starting offset is given, the check is applied
+ only to that part of the subject that could be inspected during match-
+ ing, and there is a check that the starting offset points to the first
+ code unit of a character or to the end of the subject. If there are no
+ lookbehind assertions in the pattern, the check starts at the starting
+ offset. Otherwise, it starts at the length of the longest lookbehind
+ before the starting offset, or at the start of the subject if there are
+ not that many characters before the starting offset. Note that the
+ sequences \b and \B are one-character lookbehinds.
+
+ The check is carried out before any other processing takes place, and a
+ negative error code is returned if the check fails. There are several
+ UTF error codes for each code unit width, corresponding to different
+ problems with the code unit sequence. There are discussions about the
+ validity of UTF-8 strings, UTF-16 strings, and UTF-32 strings in the
+ pcre2unicode page.
+
+ If you know that your subject is valid, and you want to skip these
+ checks for performance reasons, you can set the PCRE2_NO_UTF_CHECK
+ option when calling pcre2_match(). You might want to do this for the
+ second and subsequent calls to pcre2_match() if you are making repeated
+ calls to find all the matches in a single subject string.
+
+ NOTE: When PCRE2_NO_UTF_CHECK is set, the effect of passing an invalid
+ string as a subject, or an invalid value of startoffset, is undefined.
+ Your program may crash or loop indefinitely.
+
+ PCRE2_PARTIAL_HARD
+ PCRE2_PARTIAL_SOFT
+
+ These options turn on the partial matching feature. A partial match
+ occurs if the end of the subject string is reached successfully, but
+ there are not enough subject characters to complete the match. If this
+ happens when PCRE2_PARTIAL_SOFT (but not PCRE2_PARTIAL_HARD) is set,
+ matching continues by testing any remaining alternatives. Only if no
+ complete match can be found is PCRE2_ERROR_PARTIAL returned instead of
+ PCRE2_ERROR_NOMATCH. In other words, PCRE2_PARTIAL_SOFT specifies that
+ the caller is prepared to handle a partial match, but only if no com-
+ plete match can be found.
+
+ If PCRE2_PARTIAL_HARD is set, it overrides PCRE2_PARTIAL_SOFT. In this
+ case, if a partial match is found, pcre2_match() immediately returns
+ PCRE2_ERROR_PARTIAL, without considering any other alternatives. In
+ other words, when PCRE2_PARTIAL_HARD is set, a partial match is consid-
+ ered to be more important that an alternative complete match.
+
+ There is a more detailed discussion of partial and multi-segment match-
+ ing, with examples, in the pcre2partial documentation.
+
+
+NEWLINE HANDLING WHEN MATCHING
+
+ When PCRE2 is built, a default newline convention is set; this is usu-
+ ally the standard convention for the operating system. The default can
+ be overridden in a compile context by calling pcre2_set_newline(). It
+ can also be overridden by starting a pattern string with, for example,
+ (*CRLF), as described in the section on newline conventions in the
+ pcre2pattern page. During matching, the newline choice affects the be-
+ haviour of the dot, circumflex, and dollar metacharacters. It may also
+ alter the way the match starting position is advanced after a match
+ failure for an unanchored pattern.
+
+ When PCRE2_NEWLINE_CRLF, PCRE2_NEWLINE_ANYCRLF, or PCRE2_NEWLINE_ANY is
+ set as the newline convention, and a match attempt for an unanchored
+ pattern fails when the current starting position is at a CRLF sequence,
+ and the pattern contains no explicit matches for CR or LF characters,
+ the match position is advanced by two characters instead of one, in
+ other words, to after the CRLF.
+
+ The above rule is a compromise that makes the most common cases work as
+ expected. For example, if the pattern is .+A (and the PCRE2_DOTALL
+ option is not set), it does not match the string "\r\nA" because, after
+ failing at the start, it skips both the CR and the LF before retrying.
+ However, the pattern [\r\n]A does match that string, because it con-
+ tains an explicit CR or LF reference, and so advances only by one char-
+ acter after the first failure.
+
+ An explicit match for CR of LF is either a literal appearance of one of
+ those characters in the pattern, or one of the \r or \n escape
+ sequences. Implicit matches such as [^X] do not count, nor does \s,
+ even though it includes CR and LF in the characters that it matches.
+
+ Notwithstanding the above, anomalous effects may still occur when CRLF
+ is a valid newline sequence and explicit \r or \n escapes appear in the
+ pattern.
+
+
+HOW PCRE2_MATCH() RETURNS A STRING AND CAPTURED SUBSTRINGS
+
+ uint32_t pcre2_get_ovector_count(pcre2_match_data *match_data);
+
+ PCRE2_SIZE *pcre2_get_ovector_pointer(pcre2_match_data *match_data);
+
+ In general, a pattern matches a certain portion of the subject, and in
+ addition, further substrings from the subject may be picked out by
+ parenthesized parts of the pattern. Following the usage in Jeffrey
+ Friedl's book, this is called "capturing" in what follows, and the
+ phrase "capturing subpattern" or "capturing group" is used for a frag-
+ ment of a pattern that picks out a substring. PCRE2 supports several
+ other kinds of parenthesized subpattern that do not cause substrings to
+ be captured. The pcre2_pattern_info() function can be used to find out
+ how many capturing subpatterns there are in a compiled pattern.
+
+ You can use auxiliary functions for accessing captured substrings by
+ number or by name, as described in sections below.
+
+ Alternatively, you can make direct use of the vector of PCRE2_SIZE val-
+ ues, called the ovector, which contains the offsets of captured
+ strings. It is part of the match data block. The function
+ pcre2_get_ovector_pointer() returns the address of the ovector, and
+ pcre2_get_ovector_count() returns the number of pairs of values it con-
+ tains.
+
+ Within the ovector, the first in each pair of values is set to the off-
+ set of the first code unit of a substring, and the second is set to the
+ offset of the first code unit after the end of a substring. These val-
+ ues are always code unit offsets, not character offsets. That is, they
+ are byte offsets in the 8-bit library, 16-bit offsets in the 16-bit
+ library, and 32-bit offsets in the 32-bit library.
+
+ After a partial match (error return PCRE2_ERROR_PARTIAL), only the
+ first pair of offsets (that is, ovector[0] and ovector[1]) are set.
+ They identify the part of the subject that was partially matched. See
+ the pcre2partial documentation for details of partial matching.
+
+ After a successful match, the first pair of offsets identifies the por-
+ tion of the subject string that was matched by the entire pattern. The
+ next pair is used for the first capturing subpattern, and so on. The
+ value returned by pcre2_match() is one more than the highest numbered
+ pair that has been set. For example, if two substrings have been cap-
+ tured, the returned value is 3. If there are no capturing subpatterns,
+ the return value from a successful match is 1, indicating that just the
+ first pair of offsets has been set.
+
+ If a pattern uses the \K escape sequence within a positive assertion,
+ the reported start of a successful match can be greater than the end of
+ the match. For example, if the pattern (?=ab\K) is matched against
+ "ab", the start and end offset values for the match are 2 and 0.
+
+ If a capturing subpattern group is matched repeatedly within a single
+ match operation, it is the last portion of the subject that it matched
+ that is returned.
+
+ If the ovector is too small to hold all the captured substring offsets,
+ as much as possible is filled in, and the function returns a value of
+ zero. If captured substrings are not of interest, pcre2_match() may be
+ called with a match data block whose ovector is of minimum length (that
+ is, one pair). However, if the pattern contains back references and the
+ ovector is not big enough to remember the related substrings, PCRE2 has
+ to get additional memory for use during matching. Thus it is usually
+ advisable to set up a match data block containing an ovector of reason-
+ able size.
+
+ It is possible for capturing subpattern number n+1 to match some part
+ of the subject when subpattern n has not been used at all. For example,
+ if the string "abc" is matched against the pattern (a|(z))(bc) the
+ return from the function is 4, and subpatterns 1 and 3 are matched, but
+ 2 is not. When this happens, both values in the offset pairs corre-
+ sponding to unused subpatterns are set to PCRE2_UNSET.
+
+ Offset values that correspond to unused subpatterns at the end of the
+ expression are also set to PCRE2_UNSET. For example, if the string
+ "abc" is matched against the pattern (abc)(x(yz)?)? subpatterns 2 and 3
+ are not matched. The return from the function is 2, because the high-
+ est used capturing subpattern number is 1. The offsets for for the sec-
+ ond and third capturing subpatterns (assuming the vector is large
+ enough, of course) are set to PCRE2_UNSET.
+
+ Elements in the ovector that do not correspond to capturing parentheses
+ in the pattern are never changed. That is, if a pattern contains n cap-
+ turing parentheses, no more than ovector[0] to ovector[2n+1] are set by
+ pcre2_match(). The other elements retain whatever values they previ-
+ ously had.
+
+
+OTHER INFORMATION ABOUT A MATCH
+
+ PCRE2_SPTR pcre2_get_mark(pcre2_match_data *match_data);
+
+ PCRE2_SIZE pcre2_get_startchar(pcre2_match_data *match_data);
+
+ As well as the offsets in the ovector, other information about a match
+ is retained in the match data block and can be retrieved by the above
+ functions in appropriate circumstances. If they are called at other
+ times, the result is undefined.
+
+ After a successful match, a partial match (PCRE2_ERROR_PARTIAL), or a
+ failure to match (PCRE2_ERROR_NOMATCH), a (*MARK) name may be avail-
+ able, and pcre2_get_mark() can be called. It returns a pointer to the
+ zero-terminated name, which is within the compiled pattern. Otherwise
+ NULL is returned. The length of the (*MARK) name (excluding the termi-
+ nating zero) is stored in the code unit that preceeds the name. You
+ should use this instead of relying on the terminating zero if the
+ (*MARK) name might contain a binary zero.
+
+ After a successful match, the (*MARK) name that is returned is the last
+ one encountered on the matching path through the pattern. After a "no
+ match" or a partial match, the last encountered (*MARK) name is
+ returned. For example, consider this pattern:
+
+ ^(*MARK:A)((*MARK:B)a|b)c
+
+ When it matches "bc", the returned mark is A. The B mark is "seen" in
+ the first branch of the group, but it is not on the matching path. On
+ the other hand, when this pattern fails to match "bx", the returned
+ mark is B.
+
+ After a successful match, a partial match, or one of the invalid UTF
+ errors (for example, PCRE2_ERROR_UTF8_ERR5), pcre2_get_startchar() can
+ be called. After a successful or partial match it returns the code unit
+ offset of the character at which the match started. For a non-partial
+ match, this can be different to the value of ovector[0] if the pattern
+ contains the \K escape sequence. After a partial match, however, this
+ value is always the same as ovector[0] because \K does not affect the
+ result of a partial match.
+
+ After a UTF check failure, pcre2_get_startchar() can be used to obtain
+ the code unit offset of the invalid UTF character. Details are given in
+ the pcre2unicode page.
+
+
+ERROR RETURNS FROM pcre2_match()
+
+ If pcre2_match() fails, it returns a negative number. This can be con-
+ verted to a text string by calling pcre2_get_error_message(). Negative
+ error codes are also returned by other functions, and are documented
+ with them. The codes are given names in the header file. If UTF check-
+ ing is in force and an invalid UTF subject string is detected, one of a
+ number of UTF-specific negative error codes is returned. Details are
+ given in the pcre2unicode page. The following are the other errors that
+ may be returned by pcre2_match():
+
+ PCRE2_ERROR_NOMATCH
+
+ The subject string did not match the pattern.
+
+ PCRE2_ERROR_PARTIAL
+
+ The subject string did not match, but it did match partially. See the
+ pcre2partial documentation for details of partial matching.
+
+ PCRE2_ERROR_BADMAGIC
+
+ PCRE2 stores a 4-byte "magic number" at the start of the compiled code,
+ to catch the case when it is passed a junk pointer. This is the error
+ that is returned when the magic number is not present.
+
+ PCRE2_ERROR_BADMODE
+
+ This error is given when a pattern that was compiled by the 8-bit
+ library is passed to a 16-bit or 32-bit library function, or vice
+ versa.
+
+ PCRE2_ERROR_BADOFFSET
+
+ The value of startoffset was greater than the length of the subject.
+
+ PCRE2_ERROR_BADOPTION
+
+ An unrecognized bit was set in the options argument.
+
+ PCRE2_ERROR_BADUTFOFFSET
+
+ The UTF code unit sequence that was passed as a subject was checked and
+ found to be valid (the PCRE2_NO_UTF_CHECK option was not set), but the
+ value of startoffset did not point to the beginning of a UTF character
+ or the end of the subject.
+
+ PCRE2_ERROR_CALLOUT
+
+ This error is never generated by pcre2_match() itself. It is provided
+ for use by callout functions that want to cause pcre2_match() or
+ pcre2_callout_enumerate() to return a distinctive error code. See the
+ pcre2callout documentation for details.
+
+ PCRE2_ERROR_INTERNAL
+
+ An unexpected internal error has occurred. This error could be caused
+ by a bug in PCRE2 or by overwriting of the compiled pattern.
+
+ PCRE2_ERROR_JIT_BADOPTION
+
+ This error is returned when a pattern that was successfully studied
+ using JIT is being matched, but the matching mode (partial or complete
+ match) does not correspond to any JIT compilation mode. When the JIT
+ fast path function is used, this error may be also given for invalid
+ options. See the pcre2jit documentation for more details.
+
+ PCRE2_ERROR_JIT_STACKLIMIT
+
+ This error is returned when a pattern that was successfully studied
+ using JIT is being matched, but the memory available for the just-in-
+ time processing stack is not large enough. See the pcre2jit documenta-
+ tion for more details.
+
+ PCRE2_ERROR_MATCHLIMIT
+
+ The backtracking limit was reached.
+
+ PCRE2_ERROR_NOMEMORY
+
+ If a pattern contains back references, but the ovector is not big
+ enough to remember the referenced substrings, PCRE2 gets a block of
+ memory at the start of matching to use for this purpose. There are some
+ other special cases where extra memory is needed during matching. This
+ error is given when memory cannot be obtained.
+
+ PCRE2_ERROR_NULL
+
+ Either the code, subject, or match_data argument was passed as NULL.
+
+ PCRE2_ERROR_RECURSELOOP
+
+ This error is returned when pcre2_match() detects a recursion loop
+ within the pattern. Specifically, it means that either the whole pat-
+ tern or a subpattern has been called recursively for the second time at
+ the same position in the subject string. Some simple patterns that
+ might do this are detected and faulted at compile time, but more com-
+ plicated cases, in particular mutual recursions between two different
+ subpatterns, cannot be detected until matching is attempted.
+
+ PCRE2_ERROR_RECURSIONLIMIT
+
+ The internal recursion limit was reached.
+
+
+EXTRACTING CAPTURED SUBSTRINGS BY NUMBER
+
+ int pcre2_substring_length_bynumber(pcre2_match_data *match_data,
+ uint32_t number, PCRE2_SIZE *length);
+
+ int pcre2_substring_copy_bynumber(pcre2_match_data *match_data,
+ uint32_t number, PCRE2_UCHAR *buffer,
+ PCRE2_SIZE *bufflen);
+
+ int pcre2_substring_get_bynumber(pcre2_match_data *match_data,
+ uint32_t number, PCRE2_UCHAR **bufferptr,
+ PCRE2_SIZE *bufflen);
+
+ void pcre2_substring_free(PCRE2_UCHAR *buffer);
+
+ Captured substrings can be accessed directly by using the ovector as
+ described above. For convenience, auxiliary functions are provided for
+ extracting captured substrings as new, separate, zero-terminated
+ strings. A substring that contains a binary zero is correctly extracted
+ and has a further zero added on the end, but the result is not, of
+ course, a C string.
+
+ The functions in this section identify substrings by number. The number
+ zero refers to the entire matched substring, with higher numbers refer-
+ ring to substrings captured by parenthesized groups. After a partial
+ match, only substring zero is available. An attempt to extract any
+ other substring gives the error PCRE2_ERROR_PARTIAL. The next section
+ describes similar functions for extracting captured substrings by name.
+
+ If a pattern uses the \K escape sequence within a positive assertion,
+ the reported start of a successful match can be greater than the end of
+ the match. For example, if the pattern (?=ab\K) is matched against
+ "ab", the start and end offset values for the match are 2 and 0. In
+ this situation, calling these functions with a zero substring number
+ extracts a zero-length empty string.
+
+ You can find the length in code units of a captured substring without
+ extracting it by calling pcre2_substring_length_bynumber(). The first
+ argument is a pointer to the match data block, the second is the group
+ number, and the third is a pointer to a variable into which the length
+ is placed. If you just want to know whether or not the substring has
+ been captured, you can pass the third argument as NULL.
+
+ The pcre2_substring_copy_bynumber() function copies a captured sub-
+ string into a supplied buffer, whereas pcre2_substring_get_bynumber()
+ copies it into new memory, obtained using the same memory allocation
+ function that was used for the match data block. The first two argu-
+ ments of these functions are a pointer to the match data block and a
+ capturing group number.
+
+ The final arguments of pcre2_substring_copy_bynumber() are a pointer to
+ the buffer and a pointer to a variable that contains its length in code
+ units. This is updated to contain the actual number of code units used
+ for the extracted substring, excluding the terminating zero.
+
+ For pcre2_substring_get_bynumber() the third and fourth arguments point
+ to variables that are updated with a pointer to the new memory and the
+ number of code units that comprise the substring, again excluding the
+ terminating zero. When the substring is no longer needed, the memory
+ should be freed by calling pcre2_substring_free().
+
+ The return value from all these functions is zero for success, or a
+ negative error code. If the pattern match failed, the match failure
+ code is returned. If a substring number greater than zero is used
+ after a partial match, PCRE2_ERROR_PARTIAL is returned. Other possible
+ error codes are:
+
+ PCRE2_ERROR_NOMEMORY
+
+ The buffer was too small for pcre2_substring_copy_bynumber(), or the
+ attempt to get memory failed for pcre2_substring_get_bynumber().
+
+ PCRE2_ERROR_NOSUBSTRING
+
+ There is no substring with that number in the pattern, that is, the
+ number is greater than the number of capturing parentheses.
+
+ PCRE2_ERROR_UNAVAILABLE
+
+ The substring number, though not greater than the number of captures in
+ the pattern, is greater than the number of slots in the ovector, so the
+ substring could not be captured.
+
+ PCRE2_ERROR_UNSET
+
+ The substring did not participate in the match. For example, if the
+ pattern is (abc)|(def) and the subject is "def", and the ovector con-
+ tains at least two capturing slots, substring number 1 is unset.
+
+
+EXTRACTING A LIST OF ALL CAPTURED SUBSTRINGS
+
+ int pcre2_substring_list_get(pcre2_match_data *match_data,
+ PCRE2_UCHAR ***listptr, PCRE2_SIZE **lengthsptr);
+
+ void pcre2_substring_list_free(PCRE2_SPTR *list);
+
+ The pcre2_substring_list_get() function extracts all available sub-
+ strings and builds a list of pointers to them. It also (optionally)
+ builds a second list that contains their lengths (in code units),
+ excluding a terminating zero that is added to each of them. All this is
+ done in a single block of memory that is obtained using the same memory
+ allocation function that was used to get the match data block.
+
+ This function must be called only after a successful match. If called
+ after a partial match, the error code PCRE2_ERROR_PARTIAL is returned.
+
+ The address of the memory block is returned via listptr, which is also
+ the start of the list of string pointers. The end of the list is marked
+ by a NULL pointer. The address of the list of lengths is returned via
+ lengthsptr. If your strings do not contain binary zeros and you do not
+ therefore need the lengths, you may supply NULL as the lengthsptr argu-
+ ment to disable the creation of a list of lengths. The yield of the
+ function is zero if all went well, or PCRE2_ERROR_NOMEMORY if the mem-
+ ory block could not be obtained. When the list is no longer needed, it
+ should be freed by calling pcre2_substring_list_free().
+
+ If this function encounters a substring that is unset, which can happen
+ when capturing subpattern number n+1 matches some part of the subject,
+ but subpattern n has not been used at all, it returns an empty string.
+ This can be distinguished from a genuine zero-length substring by
+ inspecting the appropriate offset in the ovector, which contain
+ PCRE2_UNSET for unset substrings, or by calling pcre2_sub-
+ string_length_bynumber().
+
+
+EXTRACTING CAPTURED SUBSTRINGS BY NAME
+
+ int pcre2_substring_number_from_name(const pcre2_code *code,
+ PCRE2_SPTR name);
+
+ int pcre2_substring_length_byname(pcre2_match_data *match_data,
+ PCRE2_SPTR name, PCRE2_SIZE *length);
+
+ int pcre2_substring_copy_byname(pcre2_match_data *match_data,
+ PCRE2_SPTR name, PCRE2_UCHAR *buffer, PCRE2_SIZE *bufflen);
+
+ int pcre2_substring_get_byname(pcre2_match_data *match_data,
+ PCRE2_SPTR name, PCRE2_UCHAR **bufferptr, PCRE2_SIZE *bufflen);
+
+ void pcre2_substring_free(PCRE2_UCHAR *buffer);
+
+ To extract a substring by name, you first have to find associated num-
+ ber. For example, for this pattern:
+
+ (a+)b(?<xxx>\d+)...
+
+ the number of the subpattern called "xxx" is 2. If the name is known to
+ be unique (PCRE2_DUPNAMES was not set), you can find the number from
+ the name by calling pcre2_substring_number_from_name(). The first argu-
+ ment is the compiled pattern, and the second is the name. The yield of
+ the function is the subpattern number, PCRE2_ERROR_NOSUBSTRING if there
+ is no subpattern of that name, or PCRE2_ERROR_NOUNIQUESUBSTRING if
+ there is more than one subpattern of that name. Given the number, you
+ can extract the substring directly, or use one of the functions
+ described above.
+
+ For convenience, there are also "byname" functions that correspond to
+ the "bynumber" functions, the only difference being that the second
+ argument is a name instead of a number. If PCRE2_DUPNAMES is set and
+ there are duplicate names, these functions scan all the groups with the
+ given name, and return the first named string that is set.
+
+ If there are no groups with the given name, PCRE2_ERROR_NOSUBSTRING is
+ returned. If all groups with the name have numbers that are greater
+ than the number of slots in the ovector, PCRE2_ERROR_UNAVAILABLE is
+ returned. If there is at least one group with a slot in the ovector,
+ but no group is found to be set, PCRE2_ERROR_UNSET is returned.
+
+ Warning: If the pattern uses the (?| feature to set up multiple subpat-
+ terns with the same number, as described in the section on duplicate
+ subpattern numbers in the pcre2pattern page, you cannot use names to
+ distinguish the different subpatterns, because names are not included
+ in the compiled code. The matching process uses only numbers. For this
+ reason, the use of different names for subpatterns of the same number
+ causes an error at compile time.
+
+
+CREATING A NEW STRING WITH SUBSTITUTIONS
+
+ int pcre2_substitute(const pcre2_code *code, PCRE2_SPTR subject,
+ PCRE2_SIZE length, PCRE2_SIZE startoffset,
+ uint32_t options, pcre2_match_data *match_data,
+ pcre2_match_context *mcontext, PCRE2_SPTR replacement,
+ PCRE2_SIZE rlength, PCRE2_UCHAR *outputbufferP,
+ PCRE2_SIZE *outlengthptr);
+
+ This function calls pcre2_match() and then makes a copy of the subject
+ string in outputbuffer, replacing the part that was matched with the
+ replacement string, whose length is supplied in rlength. This can be
+ given as PCRE2_ZERO_TERMINATED for a zero-terminated string. Matches in
+ which a \K item in a lookahead in the pattern causes the match to end
+ before it starts are not supported, and give rise to an error return.
+
+ The first seven arguments of pcre2_substitute() are the same as for
+ pcre2_match(), except that the partial matching options are not permit-
+ ted, and match_data may be passed as NULL, in which case a match data
+ block is obtained and freed within this function, using memory manage-
+ ment functions from the match context, if provided, or else those that
+ were used to allocate memory for the compiled code.
+
+ The outlengthptr argument must point to a variable that contains the
+ length, in code units, of the output buffer. If the function is suc-
+ cessful, the value is updated to contain the length of the new string,
+ excluding the trailing zero that is automatically added.
+
+ If the function is not successful, the value set via outlengthptr
+ depends on the type of error. For syntax errors in the replacement
+ string, the value is the offset in the replacement string where the
+ error was detected. For other errors, the value is PCRE2_UNSET by
+ default. This includes the case of the output buffer being too small,
+ unless PCRE2_SUBSTITUTE_OVERFLOW_LENGTH is set (see below), in which
+ case the value is the minimum length needed, including space for the
+ trailing zero. Note that in order to compute the required length,
+ pcre2_substitute() has to simulate all the matching and copying,
+ instead of giving an error return as soon as the buffer overflows. Note
+ also that the length is in code units, not bytes.
+
+ In the replacement string, which is interpreted as a UTF string in UTF
+ mode, and is checked for UTF validity unless the PCRE2_NO_UTF_CHECK
+ option is set, a dollar character is an escape character that can spec-
+ ify the insertion of characters from capturing groups or (*MARK) items
+ in the pattern. The following forms are always recognized:
+
+ $$ insert a dollar character
+ $<n> or ${<n>} insert the contents of group <n>
+ $*MARK or ${*MARK} insert the name of the last (*MARK) encountered
+
+ Either a group number or a group name can be given for <n>. Curly
+ brackets are required only if the following character would be inter-
+ preted as part of the number or name. The number may be zero to include
+ the entire matched string. For example, if the pattern a(b)c is
+ matched with "=abc=" and the replacement string "+$1$0$1+", the result
+ is "=+babcb+=".
+
+ The facility for inserting a (*MARK) name can be used to perform simple
+ simultaneous substitutions, as this pcre2test example shows:
+
+ /(*:pear)apple|(*:orange)lemon/g,replace=${*MARK}
+ apple lemon
+ 2: pear orange
+
+ As well as the usual options for pcre2_match(), a number of additional
+ options can be set in the options argument.
+
+ PCRE2_SUBSTITUTE_GLOBAL causes the function to iterate over the subject
+ string, replacing every matching substring. If this is not set, only
+ the first matching substring is replaced. If any matched substring has
+ zero length, after the substitution has happened, an attempt to find a
+ non-empty match at the same position is performed. If this is not suc-
+ cessful, the current position is advanced by one character except when
+ CRLF is a valid newline sequence and the next two characters are CR,
+ LF. In this case, the current position is advanced by two characters.
+
+ PCRE2_SUBSTITUTE_OVERFLOW_LENGTH changes what happens when the output
+ buffer is too small. The default action is to return PCRE2_ERROR_NOMEM-
+ ORY immediately. If this option is set, however, pcre2_substitute()
+ continues to go through the motions of matching and substituting (with-
+ out, of course, writing anything) in order to compute the size of buf-
+ fer that is needed. This value is passed back via the outlengthptr
+ variable, with the result of the function still being
+ PCRE2_ERROR_NOMEMORY.
+
+ Passing a buffer size of zero is a permitted way of finding out how
+ much memory is needed for given substitution. However, this does mean
+ that the entire operation is carried out twice. Depending on the appli-
+ cation, it may be more efficient to allocate a large buffer and free
+ the excess afterwards, instead of using PCRE2_SUBSTITUTE_OVER-
+ FLOW_LENGTH.
+
+ PCRE2_SUBSTITUTE_UNKNOWN_UNSET causes references to capturing groups
+ that do not appear in the pattern to be treated as unset groups. This
+ option should be used with care, because it means that a typo in a
+ group name or number no longer causes the PCRE2_ERROR_NOSUBSTRING
+ error.
+
+ PCRE2_SUBSTITUTE_UNSET_EMPTY causes unset capturing groups (including
+ unknown groups when PCRE2_SUBSTITUTE_UNKNOWN_UNSET is set) to be
+ treated as empty strings when inserted as described above. If this
+ option is not set, an attempt to insert an unset group causes the
+ PCRE2_ERROR_UNSET error. This option does not influence the extended
+ substitution syntax described below.
+
+ PCRE2_SUBSTITUTE_EXTENDED causes extra processing to be applied to the
+ replacement string. Without this option, only the dollar character is
+ special, and only the group insertion forms listed above are valid.
+ When PCRE2_SUBSTITUTE_EXTENDED is set, two things change:
+
+ Firstly, backslash in a replacement string is interpreted as an escape
+ character. The usual forms such as \n or \x{ddd} can be used to specify
+ particular character codes, and backslash followed by any non-alphanu-
+ meric character quotes that character. Extended quoting can be coded
+ using \Q...\E, exactly as in pattern strings.
+
+ There are also four escape sequences for forcing the case of inserted
+ letters. The insertion mechanism has three states: no case forcing,
+ force upper case, and force lower case. The escape sequences change the
+ current state: \U and \L change to upper or lower case forcing, respec-
+ tively, and \E (when not terminating a \Q quoted sequence) reverts to
+ no case forcing. The sequences \u and \l force the next character (if
+ it is a letter) to upper or lower case, respectively, and then the
+ state automatically reverts to no case forcing. Case forcing applies to
+ all inserted characters, including those from captured groups and let-
+ ters within \Q...\E quoted sequences.
+
+ Note that case forcing sequences such as \U...\E do not nest. For exam-
+ ple, the result of processing "\Uaa\LBB\Ecc\E" is "AAbbcc"; the final
+ \E has no effect.
+
+ The second effect of setting PCRE2_SUBSTITUTE_EXTENDED is to add more
+ flexibility to group substitution. The syntax is similar to that used
+ by Bash:
+
+ ${<n>:-<string>}
+ ${<n>:+<string1>:<string2>}
+
+ As before, <n> may be a group number or a name. The first form speci-
+ fies a default value. If group <n> is set, its value is inserted; if
+ not, <string> is expanded and the result inserted. The second form
+ specifies strings that are expanded and inserted when group <n> is set
+ or unset, respectively. The first form is just a convenient shorthand
+ for
+
+ ${<n>:+${<n>}:<string>}
+
+ Backslash can be used to escape colons and closing curly brackets in
+ the replacement strings. A change of the case forcing state within a
+ replacement string remains in force afterwards, as shown in this
+ pcre2test example:
+
+ /(some)?(body)/substitute_extended,replace=${1:+\U:\L}HeLLo
+ body
+ 1: hello
+ somebody
+ 1: HELLO
+
+ The PCRE2_SUBSTITUTE_UNSET_EMPTY option does not affect these extended
+ substitutions. However, PCRE2_SUBSTITUTE_UNKNOWN_UNSET does cause
+ unknown groups in the extended syntax forms to be treated as unset.
+
+ If successful, pcre2_substitute() returns the number of replacements
+ that were made. This may be zero if no matches were found, and is never
+ greater than 1 unless PCRE2_SUBSTITUTE_GLOBAL is set.
+
+ In the event of an error, a negative error code is returned. Except for
+ PCRE2_ERROR_NOMATCH (which is never returned), errors from
+ pcre2_match() are passed straight back.
+
+ PCRE2_ERROR_NOSUBSTRING is returned for a non-existent substring inser-
+ tion, unless PCRE2_SUBSTITUTE_UNKNOWN_UNSET is set.
+
+ PCRE2_ERROR_UNSET is returned for an unset substring insertion (includ-
+ ing an unknown substring when PCRE2_SUBSTITUTE_UNKNOWN_UNSET is set)
+ when the simple (non-extended) syntax is used and PCRE2_SUBSTI-
+ TUTE_UNSET_EMPTY is not set.
+
+ PCRE2_ERROR_NOMEMORY is returned if the output buffer is not big
+ enough. If the PCRE2_SUBSTITUTE_OVERFLOW_LENGTH option is set, the size
+ of buffer that is needed is returned via outlengthptr. Note that this
+ does not happen by default.
+
+ PCRE2_ERROR_BADREPLACEMENT is used for miscellaneous syntax errors in
+ the replacement string, with more particular errors being
+ PCRE2_ERROR_BADREPESCAPE (invalid escape sequence), PCRE2_ERROR_REP-
+ MISSING_BRACE (closing curly bracket not found), PCRE2_BADSUBSTITUTION
+ (syntax error in extended group substitution), and PCRE2_BADSUBPATTERN
+ (the pattern match ended before it started, which can happen if \K is
+ used in an assertion).
+
+ As for all PCRE2 errors, a text message that describes the error can be
+ obtained by calling pcre2_get_error_message().
+
+
+DUPLICATE SUBPATTERN NAMES
+
+ int pcre2_substring_nametable_scan(const pcre2_code *code,
+ PCRE2_SPTR name, PCRE2_SPTR *first, PCRE2_SPTR *last);
+
+ When a pattern is compiled with the PCRE2_DUPNAMES option, names for
+ subpatterns are not required to be unique. Duplicate names are always
+ allowed for subpatterns with the same number, created by using the (?|
+ feature. Indeed, if such subpatterns are named, they are required to
+ use the same names.
+
+ Normally, patterns with duplicate names are such that in any one match,
+ only one of the named subpatterns participates. An example is shown in
+ the pcre2pattern documentation.
+
+ When duplicates are present, pcre2_substring_copy_byname() and
+ pcre2_substring_get_byname() return the first substring corresponding
+ to the given name that is set. Only if none are set is
+ PCRE2_ERROR_UNSET is returned. The pcre2_substring_number_from_name()
+ function returns the error PCRE2_ERROR_NOUNIQUESUBSTRING when there are
+ duplicate names.
+
+ If you want to get full details of all captured substrings for a given
+ name, you must use the pcre2_substring_nametable_scan() function. The
+ first argument is the compiled pattern, and the second is the name. If
+ the third and fourth arguments are NULL, the function returns a group
+ number for a unique name, or PCRE2_ERROR_NOUNIQUESUBSTRING otherwise.
+
+ When the third and fourth arguments are not NULL, they must be pointers
+ to variables that are updated by the function. After it has run, they
+ point to the first and last entries in the name-to-number table for the
+ given name, and the function returns the length of each entry in code
+ units. In both cases, PCRE2_ERROR_NOSUBSTRING is returned if there are
+ no entries for the given name.
+
+ The format of the name table is described above in the section entitled
+ Information about a pattern. Given all the relevant entries for the
+ name, you can extract each of their numbers, and hence the captured
+ data.
+
+
+FINDING ALL POSSIBLE MATCHES AT ONE POSITION
+
+ The traditional matching function uses a similar algorithm to Perl,
+ which stops when it finds the first match at a given point in the sub-
+ ject. If you want to find all possible matches, or the longest possible
+ match at a given position, consider using the alternative matching
+ function (see below) instead. If you cannot use the alternative func-
+ tion, you can kludge it up by making use of the callout facility, which
+ is described in the pcre2callout documentation.
+
+ What you have to do is to insert a callout right at the end of the pat-
+ tern. When your callout function is called, extract and save the cur-
+ rent matched substring. Then return 1, which forces pcre2_match() to
+ backtrack and try other alternatives. Ultimately, when it runs out of
+ matches, pcre2_match() will yield PCRE2_ERROR_NOMATCH.
+
+
+MATCHING A PATTERN: THE ALTERNATIVE FUNCTION
+
+ int pcre2_dfa_match(const pcre2_code *code, PCRE2_SPTR subject,
+ PCRE2_SIZE length, PCRE2_SIZE startoffset,
+ uint32_t options, pcre2_match_data *match_data,
+ pcre2_match_context *mcontext,
+ int *workspace, PCRE2_SIZE wscount);
+
+ The function pcre2_dfa_match() is called to match a subject string
+ against a compiled pattern, using a matching algorithm that scans the
+ subject string just once, and does not backtrack. This has different
+ characteristics to the normal algorithm, and is not compatible with
+ Perl. Some of the features of PCRE2 patterns are not supported. Never-
+ theless, there are times when this kind of matching can be useful. For
+ a discussion of the two matching algorithms, and a list of features
+ that pcre2_dfa_match() does not support, see the pcre2matching documen-
+ tation.
+
+ The arguments for the pcre2_dfa_match() function are the same as for
+ pcre2_match(), plus two extras. The ovector within the match data block
+ is used in a different way, and this is described below. The other com-
+ mon arguments are used in the same way as for pcre2_match(), so their
+ description is not repeated here.
+
+ The two additional arguments provide workspace for the function. The
+ workspace vector should contain at least 20 elements. It is used for
+ keeping track of multiple paths through the pattern tree. More
+ workspace is needed for patterns and subjects where there are a lot of
+ potential matches.
+
+ Here is an example of a simple call to pcre2_dfa_match():
+
+ int wspace[20];
+ pcre2_match_data *md = pcre2_match_data_create(4, NULL);
+ int rc = pcre2_dfa_match(
+ re, /* result of pcre2_compile() */
+ "some string", /* the subject string */
+ 11, /* the length of the subject string */
+ 0, /* start at offset 0 in the subject */
+ 0, /* default options */
+ match_data, /* the match data block */
+ NULL, /* a match context; NULL means use defaults */
+ wspace, /* working space vector */
+ 20); /* number of elements (NOT size in bytes) */
+
+ Option bits for pcre_dfa_match()
+
+ The unused bits of the options argument for pcre2_dfa_match() must be
+ zero. The only bits that may be set are PCRE2_ANCHORED, PCRE2_NOTBOL,
+ PCRE2_NOTEOL, PCRE2_NOTEMPTY, PCRE2_NOTEMPTY_ATSTART,
+ PCRE2_NO_UTF_CHECK, PCRE2_PARTIAL_HARD, PCRE2_PARTIAL_SOFT,
+ PCRE2_DFA_SHORTEST, and PCRE2_DFA_RESTART. All but the last four of
+ these are exactly the same as for pcre2_match(), so their description
+ is not repeated here.
+
+ PCRE2_PARTIAL_HARD
+ PCRE2_PARTIAL_SOFT
+
+ These have the same general effect as they do for pcre2_match(), but
+ the details are slightly different. When PCRE2_PARTIAL_HARD is set for
+ pcre2_dfa_match(), it returns PCRE2_ERROR_PARTIAL if the end of the
+ subject is reached and there is still at least one matching possibility
+ that requires additional characters. This happens even if some complete
+ matches have already been found. When PCRE2_PARTIAL_SOFT is set, the
+ return code PCRE2_ERROR_NOMATCH is converted into PCRE2_ERROR_PARTIAL
+ if the end of the subject is reached, there have been no complete
+ matches, but there is still at least one matching possibility. The por-
+ tion of the string that was inspected when the longest partial match
+ was found is set as the first matching string in both cases. There is a
+ more detailed discussion of partial and multi-segment matching, with
+ examples, in the pcre2partial documentation.
+
+ PCRE2_DFA_SHORTEST
+
+ Setting the PCRE2_DFA_SHORTEST option causes the matching algorithm to
+ stop as soon as it has found one match. Because of the way the alterna-
+ tive algorithm works, this is necessarily the shortest possible match
+ at the first possible matching point in the subject string.
+
+ PCRE2_DFA_RESTART
+
+ When pcre2_dfa_match() returns a partial match, it is possible to call
+ it again, with additional subject characters, and have it continue with
+ the same match. The PCRE2_DFA_RESTART option requests this action; when
+ it is set, the workspace and wscount options must reference the same
+ vector as before because data about the match so far is left in them
+ after a partial match. There is more discussion of this facility in the
+ pcre2partial documentation.
+
+ Successful returns from pcre2_dfa_match()
+
+ When pcre2_dfa_match() succeeds, it may have matched more than one sub-
+ string in the subject. Note, however, that all the matches from one run
+ of the function start at the same point in the subject. The shorter
+ matches are all initial substrings of the longer matches. For example,
+ if the pattern
+
+ <.*>
+
+ is matched against the string
+
+ This is <something> <something else> <something further> no more
+
+ the three matched strings are
+
+ <something> <something else> <something further>
+ <something> <something else>
+ <something>
+
+ On success, the yield of the function is a number greater than zero,
+ which is the number of matched substrings. The offsets of the sub-
+ strings are returned in the ovector, and can be extracted by number in
+ the same way as for pcre2_match(), but the numbers bear no relation to
+ any capturing groups that may exist in the pattern, because DFA match-
+ ing does not support group capture.
+
+ Calls to the convenience functions that extract substrings by name
+ return the error PCRE2_ERROR_DFA_UFUNC (unsupported function) if used
+ after a DFA match. The convenience functions that extract substrings by
+ number never return PCRE2_ERROR_NOSUBSTRING, and the meanings of some
+ other errors are slightly different:
+
+ PCRE2_ERROR_UNAVAILABLE
+
+ The ovector is not big enough to include a slot for the given substring
+ number.
+
+ PCRE2_ERROR_UNSET
+
+ There is a slot in the ovector for this substring, but there were
+ insufficient matches to fill it.
+
+ The matched strings are stored in the ovector in reverse order of
+ length; that is, the longest matching string is first. If there were
+ too many matches to fit into the ovector, the yield of the function is
+ zero, and the vector is filled with the longest matches.
+
+ NOTE: PCRE2's "auto-possessification" optimization usually applies to
+ character repeats at the end of a pattern (as well as internally). For
+ example, the pattern "a\d+" is compiled as if it were "a\d++". For DFA
+ matching, this means that only one possible match is found. If you
+ really do want multiple matches in such cases, either use an ungreedy
+ repeat auch as "a\d+?" or set the PCRE2_NO_AUTO_POSSESS option when
+ compiling.
+
+ Error returns from pcre2_dfa_match()
+
+ The pcre2_dfa_match() function returns a negative number when it fails.
+ Many of the errors are the same as for pcre2_match(), as described
+ above. There are in addition the following errors that are specific to
+ pcre2_dfa_match():
+
+ PCRE2_ERROR_DFA_UITEM
+
+ This return is given if pcre2_dfa_match() encounters an item in the
+ pattern that it does not support, for instance, the use of \C in a UTF
+ mode or a back reference.
+
+ PCRE2_ERROR_DFA_UCOND
+
+ This return is given if pcre2_dfa_match() encounters a condition item
+ that uses a back reference for the condition, or a test for recursion
+ in a specific group. These are not supported.
+
+ PCRE2_ERROR_DFA_WSSIZE
+
+ This return is given if pcre2_dfa_match() runs out of space in the
+ workspace vector.
+
+ PCRE2_ERROR_DFA_RECURSE
+
+ When a recursive subpattern is processed, the matching function calls
+ itself recursively, using private memory for the ovector and workspace.
+ This error is given if the internal ovector is not large enough. This
+ should be extremely rare, as a vector of size 1000 is used.
+
+ PCRE2_ERROR_DFA_BADRESTART
+
+ When pcre2_dfa_match() is called with the PCRE2_DFA_RESTART option,
+ some plausibility checks are made on the contents of the workspace,
+ which should contain data about the previous partial match. If any of
+ these checks fail, this error is given.

+NAME
+ PCRE2 - Perl-compatible regular expressions (revised API)
+
+BUILDING PCRE2
+
+ PCRE2 is distributed with a configure script that can be used to build
+ the library in Unix-like environments using the applications known as
+ Autotools. Also in the distribution are files to support building using
+ CMake instead of configure. The text file README contains general
+ information about building with Autotools (some of which is repeated
+ below), and also has some comments about building on various operating
+ systems. There is a lot more information about building PCRE2 without
+ using Autotools (including information about using CMake and building
+ "by hand") in the text file called NON-AUTOTOOLS-BUILD. You should
+ consult this file as well as the README file if you are building in a
+ non-Unix-like environment.
+
+
+PCRE2 BUILD-TIME OPTIONS
+
+ The rest of this document describes the optional features of PCRE2 that
+ can be selected when the library is compiled. It assumes use of the
+ configure script, where the optional features are selected or dese-
+ lected by providing options to configure before running the make com-
+ mand. However, the same options can be selected in both Unix-like and
+ non-Unix-like environments if you are using CMake instead of configure
+ to build PCRE2.
+
+ If you are not using Autotools or CMake, option selection can be done
+ by editing the config.h file, or by passing parameter settings to the
+ compiler, as described in NON-AUTOTOOLS-BUILD.
+
+ The complete list of options for configure (which includes the standard
+ ones such as the selection of the installation directory) can be
+ obtained by running
+
+ ./configure --help
+
+ The following sections include descriptions of options whose names
+ begin with --enable or --disable. These settings specify changes to the
+ defaults for the configure command. Because of the way that configure
+ works, --enable and --disable always come in pairs, so the complemen-
+ tary option always exists as well, but as it specifies the default, it
+ is not described.
+
+
+BUILDING 8-BIT, 16-BIT AND 32-BIT LIBRARIES
+
+ By default, a library called libpcre2-8 is built, containing functions
+ that take string arguments contained in vectors of bytes, interpreted
+ either as single-byte characters, or UTF-8 strings. You can also build
+ two other libraries, called libpcre2-16 and libpcre2-32, which process
+ strings that are contained in vectors of 16-bit and 32-bit code units,
+ respectively. These can be interpreted either as single-unit characters
+ or UTF-16/UTF-32 strings. To build these additional libraries, add one
+ or both of the following to the configure command:
+
+ --enable-pcre2-16
+ --enable-pcre2-32
+
+ If you do not want the 8-bit library, add
+
+ --disable-pcre2-8
+
+ as well. At least one of the three libraries must be built. Note that
+ the POSIX wrapper is for the 8-bit library only, and that pcre2grep is
+ an 8-bit program. Neither of these are built if you select only the
+ 16-bit or 32-bit libraries.
+
+
+BUILDING SHARED AND STATIC LIBRARIES
+
+ The Autotools PCRE2 building process uses libtool to build both shared
+ and static libraries by default. You can suppress an unwanted library
+ by adding one of
+
+ --disable-shared
+ --disable-static
+
+ to the configure command.
+
+
+UNICODE AND UTF SUPPORT
+
+ By default, PCRE2 is built with support for Unicode and UTF character
+ strings. To build it without Unicode support, add
+
+ --disable-unicode
+
+ to the configure command. This setting applies to all three libraries.
+ It is not possible to build one library with Unicode support, and
+ another without, in the same configuration.
+
+ Of itself, Unicode support does not make PCRE2 treat strings as UTF-8,
+ UTF-16 or UTF-32. To do that, applications that use the library can set
+ the PCRE2_UTF option when they call pcre2_compile() to compile a pat-
+ tern. Alternatively, patterns may be started with (*UTF) unless the
+ application has locked this out by setting PCRE2_NEVER_UTF.
+
+ UTF support allows the libraries to process character code points up to
+ 0x10ffff in the strings that they handle. It also provides support for
+ accessing the Unicode properties of such characters, using pattern
+ escapes such as \P, \p, and \X. Only the general category properties
+ such as Lu and Nd are supported. Details are given in the pcre2pattern
+ documentation.
+
+ Pattern escapes such as \d and \w do not by default make use of Unicode
+ properties. The application can request that they do by setting the
+ PCRE2_UCP option. Unless the application has set PCRE2_NEVER_UCP, a
+ pattern may also request this by starting with (*UCP).
+
+
+DISABLING THE USE OF \C
+
+ The \C escape sequence, which matches a single code unit, even in a UTF
+ mode, can cause unpredictable behaviour because it may leave the cur-
+ rent matching point in the middle of a multi-code-unit character. The
+ application can lock it out by setting the PCRE2_NEVER_BACKSLASH_C
+ option when calling pcre2_compile(). There is also a build-time option
+
+ --enable-never-backslash-C
+
+ (note the upper case C) which locks out the use of \C entirely.
+
+
+JUST-IN-TIME COMPILER SUPPORT
+
+ Just-in-time compiler support is included in the build by specifying
+
+ --enable-jit
+
+ This support is available only for certain hardware architectures. If
+ this option is set for an unsupported architecture, a building error
+ occurs. See the pcre2jit documentation for a discussion of JIT usage.
+ When JIT support is enabled, pcre2grep automatically makes use of it,
+ unless you add
+
+ --disable-pcre2grep-jit
+
+ to the "configure" command.
+
+
+NEWLINE RECOGNITION
+
+ By default, PCRE2 interprets the linefeed (LF) character as indicating
+ the end of a line. This is the normal newline character on Unix-like
+ systems. You can compile PCRE2 to use carriage return (CR) instead, by
+ adding
+
+ --enable-newline-is-cr
+
+ to the configure command. There is also an --enable-newline-is-lf
+ option, which explicitly specifies linefeed as the newline character.
+
+ Alternatively, you can specify that line endings are to be indicated by
+ the two-character sequence CRLF (CR immediately followed by LF). If you
+ want this, add
+
+ --enable-newline-is-crlf
+
+ to the configure command. There is a fourth option, specified by
+
+ --enable-newline-is-anycrlf
+
+ which causes PCRE2 to recognize any of the three sequences CR, LF, or
+ CRLF as indicating a line ending. Finally, a fifth option, specified by
+
+ --enable-newline-is-any
+
+ causes PCRE2 to recognize any Unicode newline sequence. The Unicode
+ newline sequences are the three just mentioned, plus the single charac-
+ ters VT (vertical tab, U+000B), FF (form feed, U+000C), NEL (next line,
+ U+0085), LS (line separator, U+2028), and PS (paragraph separator,
+ U+2029).
+
+ Whatever default line ending convention is selected when PCRE2 is built
+ can be overridden by applications that use the library. At build time
+ it is conventional to use the standard for your operating system.
+
+
+WHAT \R MATCHES
+
+ By default, the sequence \R in a pattern matches any Unicode newline
+ sequence, independently of what has been selected as the line ending
+ sequence. If you specify
+
+ --enable-bsr-anycrlf
+
+ the default is changed so that \R matches only CR, LF, or CRLF. What-
+ ever is selected when PCRE2 is built can be overridden by applications
+ that use the called.
+
+
+HANDLING VERY LARGE PATTERNS
+
+ Within a compiled pattern, offset values are used to point from one
+ part to another (for example, from an opening parenthesis to an alter-
+ nation metacharacter). By default, in the 8-bit and 16-bit libraries,
+ two-byte values are used for these offsets, leading to a maximum size
+ for a compiled pattern of around 64K code units. This is sufficient to
+ handle all but the most gigantic patterns. Nevertheless, some people do
+ want to process truly enormous patterns, so it is possible to compile
+ PCRE2 to use three-byte or four-byte offsets by adding a setting such
+ as
+
+ --with-link-size=3
+
+ to the configure command. The value given must be 2, 3, or 4. For the
+ 16-bit library, a value of 3 is rounded up to 4. In these libraries,
+ using longer offsets slows down the operation of PCRE2 because it has
+ to load additional data when handling them. For the 32-bit library the
+ value is always 4 and cannot be overridden; the value of --with-link-
+ size is ignored.
+
+
+AVOIDING EXCESSIVE STACK USAGE
+
+ When matching with the pcre2_match() function, PCRE2 implements back-
+ tracking by making recursive calls to an internal function called
+ match(). In environments where the size of the stack is limited, this
+ can severely limit PCRE2's operation. (The Unix environment does not
+ usually suffer from this problem, but it may sometimes be necessary to
+ increase the maximum stack size. There is a discussion in the
+ pcre2stack documentation.) An alternative approach to recursion that
+ uses memory from the heap to remember data, instead of using recursive
+ function calls, has been implemented to work round the problem of lim-
+ ited stack size. If you want to build a version of PCRE2 that works
+ this way, add
+
+ --disable-stack-for-recursion
+
+ to the configure command. By default, the system functions malloc() and
+ free() are called to manage the heap memory that is required, but cus-
+ tom memory management functions can be called instead. PCRE2 runs
+ noticeably more slowly when built in this way. This option affects only
+ the pcre2_match() function; it is not relevant for pcre2_dfa_match().
+
+
+LIMITING PCRE2 RESOURCE USAGE
+
+ Internally, PCRE2 has a function called match(), which it calls repeat-
+ edly (sometimes recursively) when matching a pattern with the
+ pcre2_match() function. By controlling the maximum number of times this
+ function may be called during a single matching operation, a limit can
+ be placed on the resources used by a single call to pcre2_match(). The
+ limit can be changed at run time, as described in the pcre2api documen-
+ tation. The default is 10 million, but this can be changed by adding a
+ setting such as
+
+ --with-match-limit=500000
+
+ to the configure command. This setting has no effect on the
+ pcre2_dfa_match() matching function.
+
+ In some environments it is desirable to limit the depth of recursive
+ calls of match() more strictly than the total number of calls, in order
+ to restrict the maximum amount of stack (or heap, if --disable-stack-
+ for-recursion is specified) that is used. A second limit controls this;
+ it defaults to the value that is set for --with-match-limit, which
+ imposes no additional constraints. However, you can set a lower limit
+ by adding, for example,
+
+ --with-match-limit-recursion=10000
+
+ to the configure command. This value can also be overridden at run
+ time.
+
+
+CREATING CHARACTER TABLES AT BUILD TIME
+
+ PCRE2 uses fixed tables for processing characters whose code points are
+ less than 256. By default, PCRE2 is built with a set of tables that are
+ distributed in the file src/pcre2_chartables.c.dist. These tables are
+ for ASCII codes only. If you add
+
+ --enable-rebuild-chartables
+
+ to the configure command, the distributed tables are no longer used.
+ Instead, a program called dftables is compiled and run. This outputs
+ the source for new set of tables, created in the default locale of your
+ C run-time system. (This method of replacing the tables does not work
+ if you are cross compiling, because dftables is run on the local host.
+ If you need to create alternative tables when cross compiling, you will
+ have to do so "by hand".)
+
+
+USING EBCDIC CODE
+
+ PCRE2 assumes by default that it will run in an environment where the
+ character code is ASCII or Unicode, which is a superset of ASCII. This
+ is the case for most computer operating systems. PCRE2 can, however, be
+ compiled to run in an 8-bit EBCDIC environment by adding
+
+ --enable-ebcdic --disable-unicode
+
+ to the configure command. This setting implies --enable-rebuild-charta-
+ bles. You should only use it if you know that you are in an EBCDIC
+ environment (for example, an IBM mainframe operating system).
+
+ It is not possible to support both EBCDIC and UTF-8 codes in the same
+ version of the library. Consequently, --enable-unicode and --enable-
+ ebcdic are mutually exclusive.
+
+ The EBCDIC character that corresponds to an ASCII LF is assumed to have
+ the value 0x15 by default. However, in some EBCDIC environments, 0x25
+ is used. In such an environment you should use
+
+ --enable-ebcdic-nl25
+
+ as well as, or instead of, --enable-ebcdic. The EBCDIC character for CR
+ has the same value as in ASCII, namely, 0x0d. Whichever of 0x15 and
+ 0x25 is not chosen as LF is made to correspond to the Unicode NEL char-
+ acter (which, in Unicode, is 0x85).
+
+ The options that select newline behaviour, such as --enable-newline-is-
+ cr, and equivalent run-time options, refer to these character values in
+ an EBCDIC environment.
+
+
+PCRE2GREP OPTIONS FOR COMPRESSED FILE SUPPORT
+
+ By default, pcre2grep reads all files as plain text. You can build it
+ so that it recognizes files whose names end in .gz or .bz2, and reads
+ them with libz or libbz2, respectively, by adding one or both of
+
+ --enable-pcre2grep-libz
+ --enable-pcre2grep-libbz2
+
+ to the configure command. These options naturally require that the rel-
+ evant libraries are installed on your system. Configuration will fail
+ if they are not.
+
+
+PCRE2GREP BUFFER SIZE
+
+ pcre2grep uses an internal buffer to hold a "window" on the file it is
+ scanning, in order to be able to output "before" and "after" lines when
+ it finds a match. The size of the buffer is controlled by a parameter
+ whose default value is 20K. The buffer itself is three times this size,
+ but because of the way it is used for holding "before" lines, the long-
+ est line that is guaranteed to be processable is the parameter size.
+ You can change the default parameter value by adding, for example,
+
+ --with-pcre2grep-bufsize=50K
+
+ to the configure command. The caller of pcre2grep can override this
+ value by using --buffer-size on the command line..
+
+
+PCRE2TEST OPTION FOR LIBREADLINE SUPPORT
+
+ If you add one of
+
+ --enable-pcre2test-libreadline
+ --enable-pcre2test-libedit
+
+ to the configure command, pcre2test is linked with the libreadline
+ orlibedit library, respectively, and when its input is from a terminal,
+ it reads it using the readline() function. This provides line-editing
+ and history facilities. Note that libreadline is GPL-licensed, so if
+ you distribute a binary of pcre2test linked in this way, there may be
+ licensing issues. These can be avoided by linking instead with libedit,
+ which has a BSD licence.
+
+ Setting --enable-pcre2test-libreadline causes the -lreadline option to
+ be added to the pcre2test build. In many operating environments with a
+ sytem-installed readline library this is sufficient. However, in some
+ environments (e.g. if an unmodified distribution version of readline is
+ in use), some extra configuration may be necessary. The INSTALL file
+ for libreadline says this:
+
+ "Readline uses the termcap functions, but does not link with
+ the termcap or curses library itself, allowing applications
+ which link with readline the to choose an appropriate library."
+
+ If your environment has not been set up so that an appropriate library
+ is automatically included, you may need to add something like
+
+ LIBS="-ncurses"
+
+ immediately before the configure command.
+
+
+INCLUDING DEBUGGING CODE
+
+ If you add
+
+ --enable-debug
+
+ to the configure command, additional debugging code is included in the
+ build. This feature is intended for use by the PCRE2 maintainers.
+
+
+DEBUGGING WITH VALGRIND SUPPORT
+
+ If you add
+
+ --enable-valgrind
+
+ to the configure command, PCRE2 will use valgrind annotations to mark
+ certain memory regions as unaddressable. This allows it to detect
+ invalid memory accesses, and is mostly useful for debugging PCRE2
+ itself.
+
+
+CODE COVERAGE REPORTING
+
+ If your C compiler is gcc, you can build a version of PCRE2 that can
+ generate a code coverage report for its test suite. To enable this, you
+ must install lcov version 1.6 or above. Then specify
+
+ --enable-coverage
+
+ to the configure command and build PCRE2 in the usual way.
+
+ Note that using ccache (a caching C compiler) is incompatible with code
+ coverage reporting. If you have configured ccache to run automatically
+ on your system, you must set the environment variable
+
+ CCACHE_DISABLE=1
+
+ before running make to build PCRE2, so that ccache is not used.
+
+ When --enable-coverage is used, the following addition targets are
+ added to the Makefile:
+
+ make coverage
+
+ This creates a fresh coverage report for the PCRE2 test suite. It is
+ equivalent to running "make coverage-reset", "make coverage-baseline",
+ "make check", and then "make coverage-report".
+
+ make coverage-reset
+
+ This zeroes the coverage counters, but does nothing else.
+
+ make coverage-baseline
+
+ This captures baseline coverage information.
+
+ make coverage-report
+
+ This creates the coverage report.
+
+ make coverage-clean-report
+
+ This removes the generated coverage report without cleaning the cover-
+ age data itself.
+
+ make coverage-clean-data
+
+ This removes the captured coverage data without removing the coverage
+ files created at compile time (*.gcno).
+
+ make coverage-clean
+
+ This cleans all coverage data including the generated coverage report.
+ For more information about code coverage, see the gcov and lcov docu-
+ mentation.

+
+DESCRIPTION
+
+ PCRE2 provides a feature called "callout", which is a means of tempo-
+ rarily passing control to the caller of PCRE2 in the middle of pattern
+ matching. The caller of PCRE2 provides an external function by putting
+ its entry point in a match context (see pcre2_set_callout() in the
+ pcre2api documentation).
+
+ Within a regular expression, (?C<arg>) indicates a point at which the
+ external function is to be called. Different callout points can be
+ identified by putting a number less than 256 after the letter C. The
+ default value is zero. Alternatively, the argument may be a delimited
+ string. The starting delimiter must be one of ` ' " ^ % # $ { and the
+ ending delimiter is the same as the start, except for {, where the end-
+ ing delimiter is }. If the ending delimiter is needed within the
+ string, it must be doubled. For example, this pattern has two callout
+ points:
+
+ (?C1)abc(?C"some ""arbitrary"" text")def
+
+ If the PCRE2_AUTO_CALLOUT option bit is set when a pattern is compiled,
+ PCRE2 automatically inserts callouts, all with number 255, before each
+ item in the pattern. For example, if PCRE2_AUTO_CALLOUT is used with
+ the pattern
+
+ A(\d{2}|--)
+
+ it is processed as if it were
+
+ (?C255)A(?C255)((?C255)\d{2}(?C255)|(?C255)-(?C255)-(?C255))(?C255)
+
+ Notice that there is a callout before and after each parenthesis and
+ alternation bar. If the pattern contains a conditional group whose con-
+ dition is an assertion, an automatic callout is inserted immediately
+ before the condition. Such a callout may also be inserted explicitly,
+ for example:
+
+ (?(?C9)(?=a)ab|de) (?(?C%text%)(?!=d)ab|de)
+
+ This applies only to assertion conditions (because they are themselves
+ independent groups).
+
+ Callouts can be useful for tracking the progress of pattern matching.
+ The pcre2test program has a pattern qualifier (/auto_callout) that sets
+ automatic callouts. When any callouts are present, the output from
+ pcre2test indicates how the pattern is being matched. This is useful
+ information when you are trying to optimize the performance of a par-
+ ticular pattern.
+
+
+MISSING CALLOUTS
+
+ You should be aware that, because of optimizations in the way PCRE2
+ compiles and matches patterns, callouts sometimes do not happen exactly
+ as you might expect.
+
+ Auto-possessification
+
+ At compile time, PCRE2 "auto-possessifies" repeated items when it knows
+ that what follows cannot be part of the repeat. For example, a+[bc] is
+ compiled as if it were a++[bc]. The pcre2test output when this pattern
+ is compiled with PCRE2_ANCHORED and PCRE2_AUTO_CALLOUT and then applied
+ to the string "aaaa" is:
+
+ --->aaaa
+ +0 ^ a+
+ +2 ^ ^ [bc]
+ No match
+
+ This indicates that when matching [bc] fails, there is no backtracking
+ into a+ and therefore the callouts that would be taken for the back-
+ tracks do not occur. You can disable the auto-possessify feature by
+ passing PCRE2_NO_AUTO_POSSESS to pcre2_compile(), or starting the pat-
+ tern with (*NO_AUTO_POSSESS). In this case, the output changes to this:
+
+ --->aaaa
+ +0 ^ a+
+ +2 ^ ^ [bc]
+ +2 ^ ^ [bc]
+ +2 ^ ^ [bc]
+ +2 ^^ [bc]
+ No match
+
+ This time, when matching [bc] fails, the matcher backtracks into a+ and
+ tries again, repeatedly, until a+ itself fails.
+
+ Automatic .* anchoring
+
+ By default, an optimization is applied when .* is the first significant
+ item in a pattern. If PCRE2_DOTALL is set, so that the dot can match
+ any character, the pattern is automatically anchored. If PCRE2_DOTALL
+ is not set, a match can start only after an internal newline or at the
+ beginning of the subject, and pcre2_compile() remembers this. This
+ optimization is disabled, however, if .* is in an atomic group or if
+ there is a back reference to the capturing group in which it appears.
+ It is also disabled if the pattern contains (*PRUNE) or (*SKIP). How-
+ ever, the presence of callouts does not affect it.
+
+ For example, if the pattern .*\d is compiled with PCRE2_AUTO_CALLOUT
+ and applied to the string "aa", the pcre2test output is:
+
+ --->aa
+ +0 ^ .*
+ +2 ^ ^ \d
+ +2 ^^ \d
+ +2 ^ \d
+ No match
+
+ This shows that all match attempts start at the beginning of the sub-
+ ject. In other words, the pattern is anchored. You can disable this
+ optimization by passing PCRE2_NO_DOTSTAR_ANCHOR to pcre2_compile(), or
+ starting the pattern with (*NO_DOTSTAR_ANCHOR). In this case, the out-
+ put changes to:
+
+ --->aa
+ +0 ^ .*
+ +2 ^ ^ \d
+ +2 ^^ \d
+ +2 ^ \d
+ +0 ^ .*
+ +2 ^^ \d
+ +2 ^ \d
+ No match
+
+ This shows more match attempts, starting at the second subject charac-
+ ter. Another optimization, described in the next section, means that
+ there is no subsequent attempt to match with an empty subject.
+
+ If a pattern has more than one top-level branch, automatic anchoring
+ occurs if all branches are anchorable.
+
+ Other optimizations
+
+ Other optimizations that provide fast "no match" results also affect
+ callouts. For example, if the pattern is
+
+ ab(?C4)cd
+
+ PCRE2 knows that any matching string must contain the letter "d". If
+ the subject string is "abyz", the lack of "d" means that matching
+ doesn't ever start, and the callout is never reached. However, with
+ "abyd", though the result is still no match, the callout is obeyed.
+
+ PCRE2 also knows the minimum length of a matching string, and will
+ immediately give a "no match" return without actually running a match
+ if the subject is not long enough, or, for unanchored patterns, if it
+ has been scanned far enough.
+
+ You can disable these optimizations by passing the PCRE2_NO_START_OPTI-
+ MIZE option to pcre2_compile(), or by starting the pattern with
+ (*NO_START_OPT). This slows down the matching process, but does ensure
+ that callouts such as the example above are obeyed.
+
+
+THE CALLOUT INTERFACE
+
+ During matching, when PCRE2 reaches a callout point, if an external
+ function is set in the match context, it is called. This applies to
+ both normal and DFA matching. The first argument to the callout func-
+ tion is a pointer to a pcre2_callout block. The second argument is the
+ void * callout data that was supplied when the callout was set up by
+ calling pcre2_set_callout() (see the pcre2api documentation). The call-
+ out block structure contains the following fields:
+
+ uint32_t version;
+ uint32_t callout_number;
+ uint32_t capture_top;
+ uint32_t capture_last;
+ PCRE2_SIZE *offset_vector;
+ PCRE2_SPTR mark;
+ PCRE2_SPTR subject;
+ PCRE2_SIZE subject_length;
+ PCRE2_SIZE start_match;
+ PCRE2_SIZE current_position;
+ PCRE2_SIZE pattern_position;
+ PCRE2_SIZE next_item_length;
+ PCRE2_SIZE callout_string_offset;
+ PCRE2_SIZE callout_string_length;
+ PCRE2_SPTR callout_string;
+
+ The version field contains the version number of the block format. The
+ current version is 1; the three callout string fields were added for
+ this version. If you are writing an application that might use an ear-
+ lier release of PCRE2, you should check the version number before
+ accessing any of these fields. The version number will increase in
+ future if more fields are added, but the intention is never to remove
+ any of the existing fields.
+
+ Fields for numerical callouts
+
+ For a numerical callout, callout_string is NULL, and callout_number
+ contains the number of the callout, in the range 0-255. This is the
+ number that follows (?C for manual callouts; it is 255 for automati-
+ cally generated callouts.
+
+ Fields for string callouts
+
+ For callouts with string arguments, callout_number is always zero, and
+ callout_string points to the string that is contained within the com-
+ piled pattern. Its length is given by callout_string_length. Duplicated
+ ending delimiters that were present in the original pattern string have
+ been turned into single characters, but there is no other processing of
+ the callout string argument. An additional code unit containing binary
+ zero is present after the string, but is not included in the length.
+ The delimiter that was used to start the string is also stored within
+ the pattern, immediately before the string itself. You can access this
+ delimiter as callout_string[-1] if you need it.
+
+ The callout_string_offset field is the code unit offset to the start of
+ the callout argument string within the original pattern string. This is
+ provided for the benefit of applications such as script languages that
+ might need to report errors in the callout string within the pattern.
+
+ Fields for all callouts
+
+ The remaining fields in the callout block are the same for both kinds
+ of callout.
+
+ The offset_vector field is a pointer to the vector of capturing offsets
+ (the "ovector") that was passed to the matching function in the match
+ data block. When pcre2_match() is used, the contents can be inspected
+ in order to extract substrings that have been matched so far, in the
+ same way as for extracting substrings after a match has completed. For
+ the DFA matching function, this field is not useful.
+
+ The subject and subject_length fields contain copies of the values that
+ were passed to the matching function.
+
+ The start_match field normally contains the offset within the subject
+ at which the current match attempt started. However, if the escape
+ sequence \K has been encountered, this value is changed to reflect the
+ modified starting point. If the pattern is not anchored, the callout
+ function may be called several times from the same point in the pattern
+ for different starting points in the subject.
+
+ The current_position field contains the offset within the subject of
+ the current match pointer.
+
+ When the pcre2_match() is used, the capture_top field contains one more
+ than the number of the highest numbered captured substring so far. If
+ no substrings have been captured, the value of capture_top is one. This
+ is always the case when the DFA functions are used, because they do not
+ support captured substrings.
+
+ The capture_last field contains the number of the most recently cap-
+ tured substring. However, when a recursion exits, the value reverts to
+ what it was outside the recursion, as do the values of all captured
+ substrings. If no substrings have been captured, the value of cap-
+ ture_last is 0. This is always the case for the DFA matching functions.
+
+ The pattern_position field contains the offset in the pattern string to
+ the next item to be matched.
+
+ The next_item_length field contains the length of the next item to be
+ matched in the pattern string. When the callout immediately precedes an
+ alternation bar, a closing parenthesis, or the end of the pattern, the
+ length is zero. When the callout precedes an opening parenthesis, the
+ length is that of the entire subpattern.
+
+ The pattern_position and next_item_length fields are intended to help
+ in distinguishing between different automatic callouts, which all have
+ the same callout number. However, they are set for all callouts, and
+ are used by pcre2test to show the next item to be matched when display-
+ ing callout information.
+
+ In callouts from pcre2_match() the mark field contains a pointer to the
+ zero-terminated name of the most recently passed (*MARK), (*PRUNE), or
+ (*THEN) item in the match, or NULL if no such items have been passed.
+ Instances of (*PRUNE) or (*THEN) without a name do not obliterate a
+ previous (*MARK). In callouts from the DFA matching function this field
+ always contains NULL.
+
+
+RETURN VALUES FROM CALLOUTS
+
+ The external callout function returns an integer to PCRE2. If the value
+ is zero, matching proceeds as normal. If the value is greater than
+ zero, matching fails at the current point, but the testing of other
+ matching possibilities goes ahead, just as if a lookahead assertion had
+ failed. If the value is less than zero, the match is abandoned, and the
+ matching function returns the negative value.
+
+ Negative values should normally be chosen from the set of
+ PCRE2_ERROR_xxx values. In particular, PCRE2_ERROR_NOMATCH forces a
+ standard "no match" failure. The error number PCRE2_ERROR_CALLOUT is
+ reserved for use by callout functions; it will never be used by PCRE2
+ itself.
+
+
+CALLOUT ENUMERATION
+
+ int pcre2_callout_enumerate(const pcre2_code *code,
+ int (*callback)(pcre2_callout_enumerate_block *, void *),
+ void *user_data);
+
+ A script language that supports the use of string arguments in callouts
+ might like to scan all the callouts in a pattern before running the
+ match. This can be done by calling pcre2_callout_enumerate(). The first
+ argument is a pointer to a compiled pattern, the second points to a
+ callback function, and the third is arbitrary user data. The callback
+ function is called for every callout in the pattern in the order in
+ which they appear. Its first argument is a pointer to a callout enumer-
+ ation block, and its second argument is the user_data value that was
+ passed to pcre2_callout_enumerate(). The data block contains the fol-
+ lowing fields:
+
+ version Block version number
+ pattern_position Offset to next item in pattern
+ next_item_length Length of next item in pattern
+ callout_number Number for numbered callouts
+ callout_string_offset Offset to string within pattern
+ callout_string_length Length of callout string
+ callout_string Points to callout string or is NULL
+
+ The version number is currently 0. It will increase if new fields are
+ ever added to the block. The remaining fields are the same as their
+ namesakes in the pcre2_callout block that is used for callouts during
+ matching, as described above.
+
+ Note that the value of pattern_position is unique for each callout.
+ However, if a callout occurs inside a group that is quantified with a
+ non-zero minimum or a fixed maximum, the group is replicated inside the
+ compiled pattern. For example, a pattern such as /(a){2}/ is compiled
+ as if it were /(a)(a)/. This means that the callout will be enumerated
+ more than once, but with the same value for pattern_position in each
+ case.
+
+ The callback function should normally return zero. If it returns a non-
+ zero value, scanning the pattern stops, and that value is returned from
+ pcre2_callout_enumerate().

+PCRE2COMPAT(3) Library Functions Manual PCRE2COMPAT(3)
+
+
+
+NAME
+ PCRE2 - Perl-compatible regular expressions (revised API)
+
+DIFFERENCES BETWEEN PCRE2 AND PERL
+
+ This document describes the differences in the ways that PCRE2 and Perl
+ handle regular expressions. The differences described here are with
+ respect to Perl versions 5.10 and above.
+
+ 1. PCRE2 has only a subset of Perl's Unicode support. Details of what
+ it does have are given in the pcre2unicode page.
+
+ 2. PCRE2 allows repeat quantifiers only on parenthesized assertions,
+ but they do not mean what you might think. For example, (?!a){3} does
+ not assert that the next three characters are not "a". It just asserts
+ that the next character is not "a" three times (in principle: PCRE2
+ optimizes this to run the assertion just once). Perl allows repeat
+ quantifiers on other assertions such as \b, but these do not seem to
+ have any use.
+
+ 3. Capturing subpatterns that occur inside negative lookahead asser-
+ tions are counted, but their entries in the offsets vector are never
+ set. Perl sometimes (but not always) sets its numerical variables from
+ inside negative assertions.
+
+ 4. The following Perl escape sequences are not supported: \l, \u, \L,
+ \U, and \N when followed by a character name or Unicode value. (\N on
+ its own, matching a non-newline character, is supported.) In fact these
+ are implemented by Perl's general string-handling and are not part of
+ its pattern matching engine. If any of these are encountered by PCRE2,
+ an error is generated by default. However, if the PCRE2_ALT_BSUX option
+ is set, \U and \u are interpreted as ECMAScript interprets them.
+
+ 5. The Perl escape sequences \p, \P, and \X are supported only if PCRE2
+ is built with Unicode support. The properties that can be tested with
+ \p and \P are limited to the general category properties such as Lu and
+ Nd, script names such as Greek or Han, and the derived properties Any
+ and L&. PCRE2 does support the Cs (surrogate) property, which Perl does
+ not; the Perl documentation says "Because Perl hides the need for the
+ user to understand the internal representation of Unicode characters,
+ there is no need to implement the somewhat messy concept of surro-
+ gates."
+
+ 6. PCRE2 does support the \Q...\E escape for quoting substrings. Char-
+ acters in between are treated as literals. This is slightly different
+ from Perl in that $ and @ are also handled as literals inside the
+ quotes. In Perl, they cause variable interpolation (but of course PCRE2
+ does not have variables). Note the following examples:
+
+ Pattern PCRE2 matches Perl matches
+
+ \Qabc$xyz\E abc$xyz abc followed by the
+ contents of $xyz
+ \Qabc\$xyz\E abc\$xyz abc\$xyz
+ \Qabc\E\$\Qxyz\E abc$xyz abc$xyz
+
+ The \Q...\E sequence is recognized both inside and outside character
+ classes.
+
+ 7. Fairly obviously, PCRE2 does not support the (?{code}) and
+ (??{code}) constructions. However, there is support for recursive pat-
+ terns. This is not available in Perl 5.8, but it is in Perl 5.10. Also,
+ the PCRE2 "callout" feature allows an external function to be called
+ during pattern matching. See the pcre2callout documentation for
+ details.
+
+ 8. Subroutine calls (whether recursive or not) are treated as atomic
+ groups. Atomic recursion is like Python, but unlike Perl. Captured
+ values that are set outside a subroutine call can be referenced from
+ inside in PCRE2, but not in Perl. There is a discussion that explains
+ these differences in more detail in the section on recursion differ-
+ ences from Perl in the pcre2pattern page.
+
+ 9. If any of the backtracking control verbs are used in a subpattern
+ that is called as a subroutine (whether or not recursively), their
+ effect is confined to that subpattern; it does not extend to the sur-
+ rounding pattern. This is not always the case in Perl. In particular,
+ if (*THEN) is present in a group that is called as a subroutine, its
+ action is limited to that group, even if the group does not contain any
+ | characters. Note that such subpatterns are processed as anchored at
+ the point where they are tested.
+
+ 10. If a pattern contains more than one backtracking control verb, the
+ first one that is backtracked onto acts. For example, in the pattern
+ A(*COMMIT)B(*PRUNE)C a failure in B triggers (*COMMIT), but a failure
+ in C triggers (*PRUNE). Perl's behaviour is more complex; in many cases
+ it is the same as PCRE2, but there are examples where it differs.
+
+ 11. Most backtracking verbs in assertions have their normal actions.
+ They are not confined to the assertion.
+
+ 12. There are some differences that are concerned with the settings of
+ captured strings when part of a pattern is repeated. For example,
+ matching "aba" against the pattern /^(a(b)?)+$/ in Perl leaves $2
+ unset, but in PCRE2 it is set to "b".
+
+ 13. PCRE2's handling of duplicate subpattern numbers and duplicate sub-
+ pattern names is not as general as Perl's. This is a consequence of the
+ fact the PCRE2 works internally just with numbers, using an external
+ table to translate between numbers and names. In particular, a pattern
+ such as (?|(?<a>A)|(?<b)B), where the two capturing parentheses have
+ the same number but different names, is not supported, and causes an
+ error at compile time. If it were allowed, it would not be possible to
+ distinguish which parentheses matched, because both names map to cap-
+ turing subpattern number 1. To avoid this confusing situation, an error
+ is given at compile time.
+
+ 14. Perl recognizes comments in some places that PCRE2 does not, for
+ example, between the ( and ? at the start of a subpattern. If the /x
+ modifier is set, Perl allows white space between ( and ? (though cur-
+ rent Perls warn that this is deprecated) but PCRE2 never does, even if
+ the PCRE2_EXTENDED option is set.
+
+ 15. Perl, when in warning mode, gives warnings for character classes
+ such as [A-\d] or [a-[:digit:]]. It then treats the hyphens as liter-
+ als. PCRE2 has no warning features, so it gives an error in these cases
+ because they are almost certainly user mistakes.
+
+ 16. In PCRE2, the upper/lower case character properties Lu and Ll are
+ not affected when case-independent matching is specified. For example,
+ \p{Lu} always matches an upper case letter. I think Perl has changed in
+ this respect; in the release at the time of writing (5.16), \p{Lu} and
+ \p{Ll} match all letters, regardless of case, when case independence is
+ specified.
+
+ 17. PCRE2 provides some extensions to the Perl regular expression
+ facilities. Perl 5.10 includes new features that are not in earlier
+ versions of Perl, some of which (such as named parentheses) have been
+ in PCRE2 for some time. This list is with respect to Perl 5.10:
+
+ (a) Although lookbehind assertions in PCRE2 must match fixed length
+ strings, each alternative branch of a lookbehind assertion can match a
+ different length of string. Perl requires them all to have the same
+ length.
+
+ (b) If PCRE2_DOLLAR_ENDONLY is set and PCRE2_MULTILINE is not set, the
+ $ meta-character matches only at the very end of the string.
+
+ (c) A backslash followed by a letter with no special meaning is
+ faulted. (Perl can be made to issue a warning.)
+
+ (d) If PCRE2_UNGREEDY is set, the greediness of the repetition quanti-
+ fiers is inverted, that is, by default they are not greedy, but if fol-
+ lowed by a question mark they are.
+
+ (e) PCRE2_ANCHORED can be used at matching time to force a pattern to
+ be tried only at the first matching position in the subject string.
+
+ (f) The PCRE2_NOTBOL, PCRE2_NOTEOL, PCRE2_NOTEMPTY,
+ PCRE2_NOTEMPTY_ATSTART, and PCRE2_NO_AUTO_CAPTURE options have no Perl
+ equivalents.
+
+ (g) The \R escape sequence can be restricted to match only CR, LF, or
+ CRLF by the PCRE2_BSR_ANYCRLF option.
+
+ (h) The callout facility is PCRE2-specific.
+
+ (i) The partial matching facility is PCRE2-specific.
+
+ (j) The alternative matching function (pcre2_dfa_match() matches in a
+ different way and is not Perl-compatible.
+
+ (k) PCRE2 recognizes some special sequences such as (*CR) at the start
+ of a pattern that set overall options that cannot be changed within the
+ pattern.

+
+NAME
+ PCRE2 - Perl-compatible regular expressions (revised API)
+
+PCRE2 JUST-IN-TIME COMPILER SUPPORT
+
+ Just-in-time compiling is a heavyweight optimization that can greatly
+ speed up pattern matching. However, it comes at the cost of extra pro-
+ cessing before the match is performed, so it is of most benefit when
+ the same pattern is going to be matched many times. This does not nec-
+ essarily mean many calls of a matching function; if the pattern is not
+ anchored, matching attempts may take place many times at various posi-
+ tions in the subject, even for a single call. Therefore, if the subject
+ string is very long, it may still pay to use JIT even for one-off
+ matches. JIT support is available for all of the 8-bit, 16-bit and
+ 32-bit PCRE2 libraries.
+
+ JIT support applies only to the traditional Perl-compatible matching
+ function. It does not apply when the DFA matching function is being
+ used. The code for this support was written by Zoltan Herczeg.
+
+
+AVAILABILITY OF JIT SUPPORT
+
+ JIT support is an optional feature of PCRE2. The "configure" option
+ --enable-jit (or equivalent CMake option) must be set when PCRE2 is
+ built if you want to use JIT. The support is limited to the following
+ hardware platforms:
+
+ ARM 32-bit (v5, v7, and Thumb2)
+ ARM 64-bit
+ Intel x86 32-bit and 64-bit
+ MIPS 32-bit and 64-bit
+ Power PC 32-bit and 64-bit
+ SPARC 32-bit
+
+ If --enable-jit is set on an unsupported platform, compilation fails.
+
+ A program can tell if JIT support is available by calling pcre2_con-
+ fig() with the PCRE2_CONFIG_JIT option. The result is 1 when JIT is
+ available, and 0 otherwise. However, a simple program does not need to
+ check this in order to use JIT. The API is implemented in a way that
+ falls back to the interpretive code if JIT is not available. For pro-
+ grams that need the best possible performance, there is also a "fast
+ path" API that is JIT-specific.
+
+
+SIMPLE USE OF JIT
+
+ To make use of the JIT support in the simplest way, all you have to do
+ is to call pcre2_jit_compile() after successfully compiling a pattern
+ with pcre2_compile(). This function has two arguments: the first is the
+ compiled pattern pointer that was returned by pcre2_compile(), and the
+ second is zero or more of the following option bits: PCRE2_JIT_COM-
+ PLETE, PCRE2_JIT_PARTIAL_HARD, or PCRE2_JIT_PARTIAL_SOFT.
+
+ If JIT support is not available, a call to pcre2_jit_compile() does
+ nothing and returns PCRE2_ERROR_JIT_BADOPTION. Otherwise, the compiled
+ pattern is passed to the JIT compiler, which turns it into machine code
+ that executes much faster than the normal interpretive code, but yields
+ exactly the same results. The returned value from pcre2_jit_compile()
+ is zero on success, or a negative error code.
+
+ There is a limit to the size of pattern that JIT supports, imposed by
+ the size of machine stack that it uses. The exact rules are not docu-
+ mented because they may change at any time, in particular, when new
+ optimizations are introduced. If a pattern is too big, a call to
+ pcre2_jit_compile() returns PCRE2_ERROR_NOMEMORY.
+
+ PCRE2_JIT_COMPLETE requests the JIT compiler to generate code for com-
+ plete matches. If you want to run partial matches using the PCRE2_PAR-
+ TIAL_HARD or PCRE2_PARTIAL_SOFT options of pcre2_match(), you should
+ set one or both of the other options as well as, or instead of
+ PCRE2_JIT_COMPLETE. The JIT compiler generates different optimized code
+ for each of the three modes (normal, soft partial, hard partial). When
+ pcre2_match() is called, the appropriate code is run if it is avail-
+ able. Otherwise, the pattern is matched using interpretive code.
+
+ You can call pcre2_jit_compile() multiple times for the same compiled
+ pattern. It does nothing if it has previously compiled code for any of
+ the option bits. For example, you can call it once with PCRE2_JIT_COM-
+ PLETE and (perhaps later, when you find you need partial matching)
+ again with PCRE2_JIT_COMPLETE and PCRE2_JIT_PARTIAL_HARD. This time it
+ will ignore PCRE2_JIT_COMPLETE and just compile code for partial match-
+ ing. If pcre2_jit_compile() is called with no option bits set, it imme-
+ diately returns zero. This is an alternative way of testing whether JIT
+ is available.
+
+ At present, it is not possible to free JIT compiled code except when
+ the entire compiled pattern is freed by calling pcre2_code_free().
+
+ In some circumstances you may need to call additional functions. These
+ are described in the section entitled "Controlling the JIT stack"
+ below.
+
+ There are some pcre2_match() options that are not supported by JIT, and
+ there are also some pattern items that JIT cannot handle. Details are
+ given below. In both cases, matching automatically falls back to the
+ interpretive code. If you want to know whether JIT was actually used
+ for a particular match, you should arrange for a JIT callback function
+ to be set up as described in the section entitled "Controlling the JIT
+ stack" below, even if you do not need to supply a non-default JIT
+ stack. Such a callback function is called whenever JIT code is about to
+ be obeyed. If the match-time options are not right for JIT execution,
+ the callback function is not obeyed.
+
+ If the JIT compiler finds an unsupported item, no JIT data is gener-
+ ated. You can find out if JIT matching is available after compiling a
+ pattern by calling pcre2_pattern_info() with the PCRE2_INFO_JITSIZE
+ option. A non-zero result means that JIT compilation was successful. A
+ result of 0 means that JIT support is not available, or the pattern was
+ not processed by pcre2_jit_compile(), or the JIT compiler was not able
+ to handle the pattern.
+
+
+UNSUPPORTED OPTIONS AND PATTERN ITEMS
+
+ The pcre2_match() options that are supported for JIT matching are
+ PCRE2_NOTBOL, PCRE2_NOTEOL, PCRE2_NOTEMPTY, PCRE2_NOTEMPTY_ATSTART,
+ PCRE2_NO_UTF_CHECK, PCRE2_PARTIAL_HARD, and PCRE2_PARTIAL_SOFT. The
+ PCRE2_ANCHORED option is not supported at match time.
+
+ The only unsupported pattern items are \C (match a single data unit)
+ when running in a UTF mode, and a callout immediately before an asser-
+ tion condition in a conditional group.
+
+
+RETURN VALUES FROM JIT MATCHING
+
+ When a pattern is matched using JIT matching, the return values are the
+ same as those given by the interpretive pcre2_match() code, with the
+ addition of one new error code: PCRE2_ERROR_JIT_STACKLIMIT. This means
+ that the memory used for the JIT stack was insufficient. See "Control-
+ ling the JIT stack" below for a discussion of JIT stack usage.
+
+ The error code PCRE2_ERROR_MATCHLIMIT is returned by the JIT code if
+ searching a very large pattern tree goes on for too long, as it is in
+ the same circumstance when JIT is not used, but the details of exactly
+ what is counted are not the same. The PCRE2_ERROR_RECURSIONLIMIT error
+ code is never returned when JIT matching is used.
+
+
+CONTROLLING THE JIT STACK
+
+ When the compiled JIT code runs, it needs a block of memory to use as a
+ stack. By default, it uses 32K on the machine stack. However, some
+ large or complicated patterns need more than this. The error
+ PCRE2_ERROR_JIT_STACKLIMIT is given when there is not enough stack.
+ Three functions are provided for managing blocks of memory for use as
+ JIT stacks. There is further discussion about the use of JIT stacks in
+ the section entitled "JIT stack FAQ" below.
+
+ The pcre2_jit_stack_create() function creates a JIT stack. Its argu-
+ ments are a starting size, a maximum size, and a general context (for
+ memory allocation functions, or NULL for standard memory allocation).
+ It returns a pointer to an opaque structure of type pcre2_jit_stack, or
+ NULL if there is an error. The pcre2_jit_stack_free() function is used
+ to free a stack that is no longer needed. (For the technically minded:
+ the address space is allocated by mmap or VirtualAlloc.)
+
+ JIT uses far less memory for recursion than the interpretive code, and
+ a maximum stack size of 512K to 1M should be more than enough for any
+ pattern.
+
+ The pcre2_jit_stack_assign() function specifies which stack JIT code
+ should use. Its arguments are as follows:
+
+ pcre2_match_context *mcontext
+ pcre2_jit_callback callback
+ void *data
+
+ The first argument is a pointer to a match context. When this is subse-
+ quently passed to a matching function, its information determines which
+ JIT stack is used. There are three cases for the values of the other
+ two options:
+
+ (1) If callback is NULL and data is NULL, an internal 32K block
+ on the machine stack is used. This is the default when a match
+ context is created.
+
+ (2) If callback is NULL and data is not NULL, data must be
+ a pointer to a valid JIT stack, the result of calling
+ pcre2_jit_stack_create().
+
+ (3) If callback is not NULL, it must point to a function that is
+ called with data as an argument at the start of matching, in
+ order to set up a JIT stack. If the return from the callback
+ function is NULL, the internal 32K stack is used; otherwise the
+ return value must be a valid JIT stack, the result of calling
+ pcre2_jit_stack_create().
+
+ A callback function is obeyed whenever JIT code is about to be run; it
+ is not obeyed when pcre2_match() is called with options that are incom-
+ patible for JIT matching. A callback function can therefore be used to
+ determine whether a match operation was executed by JIT or by the
+ interpreter.
+
+ You may safely use the same JIT stack for more than one pattern (either
+ by assigning directly or by callback), as long as the patterns are
+ matched sequentially in the same thread. Currently, the only way to set
+ up non-sequential matches in one thread is to use callouts: if a call-
+ out function starts another match, that match must use a different JIT
+ stack to the one used for currently suspended match(es).
+
+ In a multithread application, if you do not specify a JIT stack, or if
+ you assign or pass back NULL from a callback, that is thread-safe,
+ because each thread has its own machine stack. However, if you assign
+ or pass back a non-NULL JIT stack, this must be a different stack for
+ each thread so that the application is thread-safe.
+
+ Strictly speaking, even more is allowed. You can assign the same non-
+ NULL stack to a match context that is used by any number of patterns,
+ as long as they are not used for matching by multiple threads at the
+ same time. For example, you could use the same stack in all compiled
+ patterns, with a global mutex in the callback to wait until the stack
+ is available for use. However, this is an inefficient solution, and not
+ recommended.
+
+ This is a suggestion for how a multithreaded program that needs to set
+ up non-default JIT stacks might operate:
+
+ During thread initalization
+ thread_local_var = pcre2_jit_stack_create(...)
+
+ During thread exit
+ pcre2_jit_stack_free(thread_local_var)
+
+ Use a one-line callback function
+ return thread_local_var
+
+ All the functions described in this section do nothing if JIT is not
+ available.
+
+
+JIT STACK FAQ
+
+ (1) Why do we need JIT stacks?
+
+ PCRE2 (and JIT) is a recursive, depth-first engine, so it needs a stack
+ where the local data of the current node is pushed before checking its
+ child nodes. Allocating real machine stack on some platforms is diffi-
+ cult. For example, the stack chain needs to be updated every time if we
+ extend the stack on PowerPC. Although it is possible, its updating
+ time overhead decreases performance. So we do the recursion in memory.
+
+ (2) Why don't we simply allocate blocks of memory with malloc()?
+
+ Modern operating systems have a nice feature: they can reserve an
+ address space instead of allocating memory. We can safely allocate mem-
+ ory pages inside this address space, so the stack could grow without
+ moving memory data (this is important because of pointers). Thus we can
+ allocate 1M address space, and use only a single memory page (usually
+ 4K) if that is enough. However, we can still grow up to 1M anytime if
+ needed.
+
+ (3) Who "owns" a JIT stack?
+
+ The owner of the stack is the user program, not the JIT studied pattern
+ or anything else. The user program must ensure that if a stack is being
+ used by pcre2_match(), (that is, it is assigned to a match context that
+ is passed to the pattern currently running), that stack must not be
+ used by any other threads (to avoid overwriting the same memory area).
+ The best practice for multithreaded programs is to allocate a stack for
+ each thread, and return this stack through the JIT callback function.
+
+ (4) When should a JIT stack be freed?
+
+ You can free a JIT stack at any time, as long as it will not be used by
+ pcre2_match() again. When you assign the stack to a match context, only
+ a pointer is set. There is no reference counting or any other magic.
+ You can free compiled patterns, contexts, and stacks in any order, any-
+ time. Just do not call pcre2_match() with a match context pointing to
+ an already freed stack, as that will cause SEGFAULT. (Also, do not free
+ a stack currently used by pcre2_match() in another thread). You can
+ also replace the stack in a context at any time when it is not in use.
+ You should free the previous stack before assigning a replacement.
+
+ (5) Should I allocate/free a stack every time before/after calling
+ pcre2_match()?
+
+ No, because this is too costly in terms of resources. However, you
+ could implement some clever idea which release the stack if it is not
+ used in let's say two minutes. The JIT callback can help to achieve
+ this without keeping a list of patterns.
+
+ (6) OK, the stack is for long term memory allocation. But what happens
+ if a pattern causes stack overflow with a stack of 1M? Is that 1M kept
+ until the stack is freed?
+
+ Especially on embedded sytems, it might be a good idea to release mem-
+ ory sometimes without freeing the stack. There is no API for this at
+ the moment. Probably a function call which returns with the currently
+ allocated memory for any stack and another which allows releasing mem-
+ ory (shrinking the stack) would be a good idea if someone needs this.
+
+ (7) This is too much of a headache. Isn't there any better solution for
+ JIT stack handling?
+
+ No, thanks to Windows. If POSIX threads were used everywhere, we could
+ throw out this complicated API.
+
+
+FREEING JIT SPECULATIVE MEMORY
+
+ void pcre2_jit_free_unused_memory(pcre2_general_context *gcontext);
+
+ The JIT executable allocator does not free all memory when it is possi-
+ ble. It expects new allocations, and keeps some free memory around to
+ improve allocation speed. However, in low memory conditions, it might
+ be better to free all possible memory. You can cause this to happen by
+ calling pcre2_jit_free_unused_memory(). Its argument is a general con-
+ text, for custom memory management, or NULL for standard memory manage-
+ ment.
+
+
+EXAMPLE CODE
+
+ This is a single-threaded example that specifies a JIT stack without
+ using a callback. A real program should include error checking after
+ all the function calls.
+
+ int rc;
+ pcre2_code *re;
+ pcre2_match_data *match_data;
+ pcre2_match_context *mcontext;
+ pcre2_jit_stack *jit_stack;
+
+ re = pcre2_compile(pattern, PCRE2_ZERO_TERMINATED, 0,
+ &errornumber, &erroffset, NULL);
+ rc = pcre2_jit_compile(re, PCRE2_JIT_COMPLETE);
+ mcontext = pcre2_match_context_create(NULL);
+ jit_stack = pcre2_jit_stack_create(32*1024, 512*1024, NULL);
+ pcre2_jit_stack_assign(mcontext, NULL, jit_stack);
+ match_data = pcre2_match_data_create(re, 10);
+ rc = pcre2_match(re, subject, length, 0, 0, match_data, mcontext);
+ /* Process result */
+
+ pcre2_code_free(re);
+ pcre2_match_data_free(match_data);
+ pcre2_match_context_free(mcontext);
+ pcre2_jit_stack_free(jit_stack);
+
+
+JIT FAST PATH API
+
+ Because the API described above falls back to interpreted matching when
+ JIT is not available, it is convenient for programs that are written
+ for general use in many environments. However, calling JIT via
+ pcre2_match() does have a performance impact. Programs that are written
+ for use where JIT is known to be available, and which need the best
+ possible performance, can instead use a "fast path" API to call JIT
+ matching directly instead of calling pcre2_match() (obviously only for
+ patterns that have been successfully processed by pcre2_jit_compile()).
+
+ The fast path function is called pcre2_jit_match(), and it takes
+ exactly the same arguments as pcre2_match(). The return values are also
+ the same, plus PCRE2_ERROR_JIT_BADOPTION if a matching mode (partial or
+ complete) is requested that was not compiled. Unsupported option bits
+ (for example, PCRE2_ANCHORED) are ignored.
+
+ When you call pcre2_match(), as well as testing for invalid options, a
+ number of other sanity checks are performed on the arguments. For exam-
+ ple, if the subject pointer is NULL, an immediate error is given. Also,
+ unless PCRE2_NO_UTF_CHECK is set, a UTF subject string is tested for
+ validity. In the interests of speed, these checks do not happen on the
+ JIT fast path, and if invalid data is passed, the result is undefined.
+
+ Bypassing the sanity checks and the pcre2_match() wrapping can give
+ speedups of more than 10%.

+
+SIZE AND OTHER LIMITATIONS
+
+ There are some size limitations in PCRE2 but it is hoped that they will
+ never in practice be relevant.
+
+ The maximum size of a compiled pattern is approximately 64K code units
+ for the 8-bit and 16-bit libraries if PCRE2 is compiled with the
+ default internal linkage size, which is 2 bytes for these libraries. If
+ you want to process regular expressions that are truly enormous, you
+ can compile PCRE2 with an internal linkage size of 3 or 4 (when build-
+ ing the 16-bit library, 3 is rounded up to 4). See the README file in
+ the source distribution and the pcre2build documentation for details.
+ In these cases the limit is substantially larger. However, the speed
+ of execution is slower. In the 32-bit library, the internal linkage
+ size is always 4.
+
+ The maximum length of a source pattern string is essentially unlimited;
+ it is the largest number a PCRE2_SIZE variable can hold. However, the
+ program that calls pcre2_compile() can specify a smaller limit.
+
+ The maximum length (in code units) of a subject string is one less than
+ the largest number a PCRE2_SIZE variable can hold. PCRE2_SIZE is an
+ unsigned integer type, usually defined as size_t. Its maximum value
+ (that is ~(PCRE2_SIZE)0) is reserved as a special indicator for zero-
+ terminated strings and unset offsets.
+
+ Note that when using the traditional matching function, PCRE2 uses
+ recursion to handle subpatterns and indefinite repetition. This means
+ that the available stack space may limit the size of a subject string
+ that can be processed by certain patterns. For a discussion of stack
+ issues, see the pcre2stack documentation.
+
+ All values in repeating quantifiers must be less than 65536.
+
+ The maximum length of a lookbehind assertion is 65535 characters.
+
+ There is no limit to the number of parenthesized subpatterns, but there
+ can be no more than 65535 capturing subpatterns. There is, however, a
+ limit to the depth of nesting of parenthesized subpatterns of all
+ kinds. This is imposed in order to limit the amount of system stack
+ used at compile time. The limit can be specified when PCRE2 is built;
+ the default is 250.
+
+ There is a limit to the number of forward references to subsequent sub-
+ patterns of around 200,000. Repeated forward references with fixed
+ upper limits, for example, (?2){0,100} when subpattern number 2 is to
+ the right, are included in the count. There is no limit to the number
+ of backward references.
+
+ The maximum length of name for a named subpattern is 32 code units, and
+ the maximum number of named subpatterns is 10000.
+
+ The maximum length of a name in a (*MARK), (*PRUNE), (*SKIP), or
+ (*THEN) verb is 255 for the 8-bit library and 65535 for the 16-bit and
+ 32-bit libraries.

+
+PCRE2 MATCHING ALGORITHMS
+
+ This document describes the two different algorithms that are available
+ in PCRE2 for matching a compiled regular expression against a given
+ subject string. The "standard" algorithm is the one provided by the
+ pcre2_match() function. This works in the same as as Perl's matching
+ function, and provide a Perl-compatible matching operation. The just-
+ in-time (JIT) optimization that is described in the pcre2jit documenta-
+ tion is compatible with this function.
+
+ An alternative algorithm is provided by the pcre2_dfa_match() function;
+ it operates in a different way, and is not Perl-compatible. This alter-
+ native has advantages and disadvantages compared with the standard
+ algorithm, and these are described below.
+
+ When there is only one possible way in which a given subject string can
+ match a pattern, the two algorithms give the same answer. A difference
+ arises, however, when there are multiple possibilities. For example, if
+ the pattern
+
+ ^<.*>
+
+ is matched against the string
+
+ <something> <something else> <something further>
+
+ there are three possible answers. The standard algorithm finds only one
+ of them, whereas the alternative algorithm finds all three.
+
+
+REGULAR EXPRESSIONS AS TREES
+
+ The set of strings that are matched by a regular expression can be rep-
+ resented as a tree structure. An unlimited repetition in the pattern
+ makes the tree of infinite size, but it is still a tree. Matching the
+ pattern to a given subject string (from a given starting point) can be
+ thought of as a search of the tree. There are two ways to search a
+ tree: depth-first and breadth-first, and these correspond to the two
+ matching algorithms provided by PCRE2.
+
+
+THE STANDARD MATCHING ALGORITHM
+
+ In the terminology of Jeffrey Friedl's book "Mastering Regular Expres-
+ sions", the standard algorithm is an "NFA algorithm". It conducts a
+ depth-first search of the pattern tree. That is, it proceeds along a
+ single path through the tree, checking that the subject matches what is
+ required. When there is a mismatch, the algorithm tries any alterna-
+ tives at the current point, and if they all fail, it backs up to the
+ previous branch point in the tree, and tries the next alternative
+ branch at that level. This often involves backing up (moving to the
+ left) in the subject string as well. The order in which repetition
+ branches are tried is controlled by the greedy or ungreedy nature of
+ the quantifier.
+
+ If a leaf node is reached, a matching string has been found, and at
+ that point the algorithm stops. Thus, if there is more than one possi-
+ ble match, this algorithm returns the first one that it finds. Whether
+ this is the shortest, the longest, or some intermediate length depends
+ on the way the greedy and ungreedy repetition quantifiers are specified
+ in the pattern.
+
+ Because it ends up with a single path through the tree, it is rela-
+ tively straightforward for this algorithm to keep track of the sub-
+ strings that are matched by portions of the pattern in parentheses.
+ This provides support for capturing parentheses and back references.
+
+
+THE ALTERNATIVE MATCHING ALGORITHM
+
+ This algorithm conducts a breadth-first search of the tree. Starting
+ from the first matching point in the subject, it scans the subject
+ string from left to right, once, character by character, and as it does
+ this, it remembers all the paths through the tree that represent valid
+ matches. In Friedl's terminology, this is a kind of "DFA algorithm",
+ though it is not implemented as a traditional finite state machine (it
+ keeps multiple states active simultaneously).
+
+ Although the general principle of this matching algorithm is that it
+ scans the subject string only once, without backtracking, there is one
+ exception: when a lookaround assertion is encountered, the characters
+ following or preceding the current point have to be independently
+ inspected.
+
+ The scan continues until either the end of the subject is reached, or
+ there are no more unterminated paths. At this point, terminated paths
+ represent the different matching possibilities (if there are none, the
+ match has failed). Thus, if there is more than one possible match,
+ this algorithm finds all of them, and in particular, it finds the long-
+ est. The matches are returned in decreasing order of length. There is
+ an option to stop the algorithm after the first match (which is neces-
+ sarily the shortest) is found.
+
+ Note that all the matches that are found start at the same point in the
+ subject. If the pattern
+
+ cat(er(pillar)?)?
+
+ is matched against the string "the caterpillar catchment", the result
+ is the three strings "caterpillar", "cater", and "cat" that start at
+ the fifth character of the subject. The algorithm does not automati-
+ cally move on to find matches that start at later positions.
+
+ PCRE2's "auto-possessification" optimization usually applies to charac-
+ ter repeats at the end of a pattern (as well as internally). For exam-
+ ple, the pattern "a\d+" is compiled as if it were "a\d++" because there
+ is no point even considering the possibility of backtracking into the
+ repeated digits. For DFA matching, this means that only one possible
+ match is found. If you really do want multiple matches in such cases,
+ either use an ungreedy repeat ("a\d+?") or set the PCRE2_NO_AUTO_POS-
+ SESS option when compiling.
+
+ There are a number of features of PCRE2 regular expressions that are
+ not supported by the alternative matching algorithm. They are as fol-
+ lows:
+
+ 1. Because the algorithm finds all possible matches, the greedy or
+ ungreedy nature of repetition quantifiers is not relevant (though it
+ may affect auto-possessification, as just described). During matching,
+ greedy and ungreedy quantifiers are treated in exactly the same way.
+ However, possessive quantifiers can make a difference when what follows
+ could also match what is quantified, for example in a pattern like
+ this:
+
+ ^a++\w!
+
+ This pattern matches "aaab!" but not "aaa!", which would be matched by
+ a non-possessive quantifier. Similarly, if an atomic group is present,
+ it is matched as if it were a standalone pattern at the current point,
+ and the longest match is then "locked in" for the rest of the overall
+ pattern.
+
+ 2. When dealing with multiple paths through the tree simultaneously, it
+ is not straightforward to keep track of captured substrings for the
+ different matching possibilities, and PCRE2's implementation of this
+ algorithm does not attempt to do this. This means that no captured sub-
+ strings are available.
+
+ 3. Because no substrings are captured, back references within the pat-
+ tern are not supported, and cause errors if encountered.
+
+ 4. For the same reason, conditional expressions that use a backrefer-
+ ence as the condition or test for a specific group recursion are not
+ supported.
+
+ 5. Because many paths through the tree may be active, the \K escape
+ sequence, which resets the start of the match when encountered (but may
+ be on some paths and not on others), is not supported. It causes an
+ error if encountered.
+
+ 6. Callouts are supported, but the value of the capture_top field is
+ always 1, and the value of the capture_last field is always 0.
+
+ 7. The \C escape sequence, which (in the standard algorithm) always
+ matches a single code unit, even in a UTF mode, is not supported in
+ these modes, because the alternative algorithm moves through the sub-
+ ject string one character (not code unit) at a time, for all active
+ paths through the tree.
+
+ 8. Except for (*FAIL), the backtracking control verbs such as (*PRUNE)
+ are not supported. (*FAIL) is supported, and behaves like a failing
+ negative assertion.
+
+
+ADVANTAGES OF THE ALTERNATIVE ALGORITHM
+
+ Using the alternative matching algorithm provides the following advan-
+ tages:
+
+ 1. All possible matches (at a single point in the subject) are automat-
+ ically found, and in particular, the longest match is found. To find
+ more than one match using the standard algorithm, you have to do kludgy
+ things with callouts.
+
+ 2. Because the alternative algorithm scans the subject string just
+ once, and never needs to backtrack (except for lookbehinds), it is pos-
+ sible to pass very long subject strings to the matching function in
+ several pieces, checking for partial matching each time. Although it is
+ also possible to do multi-segment matching using the standard algo-
+ rithm, by retaining partially matched substrings, it is more compli-
+ cated. The pcre2partial documentation gives details of partial matching
+ and discusses multi-segment matching.
+
+
+DISADVANTAGES OF THE ALTERNATIVE ALGORITHM
+
+ The alternative algorithm suffers from a number of disadvantages:
+
+ 1. It is substantially slower than the standard algorithm. This is
+ partly because it has to search for all possible matches, but is also
+ because it is less susceptible to optimization.
+
+ 2. Capturing parentheses and back references are not supported.
+
+ 3. Although atomic groups are supported, their use does not provide the
+ performance advantage that it does for the standard algorithm.

+NAME
+ PCRE2 - Perl-compatible regular expressions
+
+PARTIAL MATCHING IN PCRE2
+
+ In normal use of PCRE2, if the subject string that is passed to a
+ matching function matches as far as it goes, but is too short to match
+ the entire pattern, PCRE2_ERROR_NOMATCH is returned. There are circum-
+ stances where it might be helpful to distinguish this case from other
+ cases in which there is no match.
+
+ Consider, for example, an application where a human is required to type
+ in data for a field with specific formatting requirements. An example
+ might be a date in the form ddmmmyy, defined by this pattern:
+
+ ^\d?\d(jan|feb|mar|apr|may|jun|jul|aug|sep|oct|nov|dec)\d\d$
+
+ If the application sees the user's keystrokes one by one, and can check
+ that what has been typed so far is potentially valid, it is able to
+ raise an error as soon as a mistake is made, by beeping and not
+ reflecting the character that has been typed, for example. This immedi-
+ ate feedback is likely to be a better user interface than a check that
+ is delayed until the entire string has been entered. Partial matching
+ can also be useful when the subject string is very long and is not all
+ available at once.
+
+ PCRE2 supports partial matching by means of the PCRE2_PARTIAL_SOFT and
+ PCRE2_PARTIAL_HARD options, which can be set when calling a matching
+ function. The difference between the two options is whether or not a
+ partial match is preferred to an alternative complete match, though the
+ details differ between the two types of matching function. If both
+ options are set, PCRE2_PARTIAL_HARD takes precedence.
+
+ If you want to use partial matching with just-in-time optimized code,
+ you must call pcre2_jit_compile() with one or both of these options:
+
+ PCRE2_JIT_PARTIAL_SOFT
+ PCRE2_JIT_PARTIAL_HARD
+
+ PCRE2_JIT_COMPLETE should also be set if you are going to run non-par-
+ tial matches on the same pattern. If the appropriate JIT mode has not
+ been compiled, interpretive matching code is used.
+
+ Setting a partial matching option disables two of PCRE2's standard
+ optimizations. PCRE2 remembers the last literal code unit in a pattern,
+ and abandons matching immediately if it is not present in the subject
+ string. This optimization cannot be used for a subject string that
+ might match only partially. PCRE2 also knows the minimum length of a
+ matching string, and does not bother to run the matching function on
+ shorter strings. This optimization is also disabled for partial match-
+ ing.
+
+
+PARTIAL MATCHING USING pcre2_match()
+
+ A partial match occurs during a call to pcre2_match() when the end of
+ the subject string is reached successfully, but matching cannot con-
+ tinue because more characters are needed. However, at least one charac-
+ ter in the subject must have been inspected. This character need not
+ form part of the final matched string; lookbehind assertions and the \K
+ escape sequence provide ways of inspecting characters before the start
+ of a matched string. The requirement for inspecting at least one char-
+ acter exists because an empty string can always be matched; without
+ such a restriction there would always be a partial match of an empty
+ string at the end of the subject.
+
+ When a partial match is returned, the first two elements in the ovector
+ point to the portion of the subject that was matched, but the values in
+ the rest of the ovector are undefined. The appearance of \K in the pat-
+ tern has no effect for a partial match. Consider this pattern:
+
+ /abc\K123/
+
+ If it is matched against "456abc123xyz" the result is a complete match,
+ and the ovector defines the matched string as "123", because \K resets
+ the "start of match" point. However, if a partial match is requested
+ and the subject string is "456abc12", a partial match is found for the
+ string "abc12", because all these characters are needed for a subse-
+ quent re-match with additional characters.
+
+ What happens when a partial match is identified depends on which of the
+ two partial matching options are set.
+
+ PCRE2_PARTIAL_SOFT WITH pcre2_match()
+
+ If PCRE2_PARTIAL_SOFT is set when pcre2_match() identifies a partial
+ match, the partial match is remembered, but matching continues as nor-
+ mal, and other alternatives in the pattern are tried. If no complete
+ match can be found, PCRE2_ERROR_PARTIAL is returned instead of
+ PCRE2_ERROR_NOMATCH.
+
+ This option is "soft" because it prefers a complete match over a par-
+ tial match. All the various matching items in a pattern behave as if
+ the subject string is potentially complete. For example, \z, \Z, and $
+ match at the end of the subject, as normal, and for \b and \B the end
+ of the subject is treated as a non-alphanumeric.
+
+ If there is more than one partial match, the first one that was found
+ provides the data that is returned. Consider this pattern:
+
+ /123\w+X|dogY/
+
+ If this is matched against the subject string "abc123dog", both alter-
+ natives fail to match, but the end of the subject is reached during
+ matching, so PCRE2_ERROR_PARTIAL is returned. The offsets are set to 3
+ and 9, identifying "123dog" as the first partial match that was found.
+ (In this example, there are two partial matches, because "dog" on its
+ own partially matches the second alternative.)
+
+ PCRE2_PARTIAL_HARD WITH pcre2_match()
+
+ If PCRE2_PARTIAL_HARD is set for pcre2_match(), PCRE2_ERROR_PARTIAL is
+ returned as soon as a partial match is found, without continuing to
+ search for possible complete matches. This option is "hard" because it
+ prefers an earlier partial match over a later complete match. For this
+ reason, the assumption is made that the end of the supplied subject
+ string may not be the true end of the available data, and so, if \z,
+ \Z, \b, \B, or $ are encountered at the end of the subject, the result
+ is PCRE2_ERROR_PARTIAL, provided that at least one character in the
+ subject has been inspected.
+
+ Comparing hard and soft partial matching
+
+ The difference between the two partial matching options can be illus-
+ trated by a pattern such as:
+
+ /dog(sbody)?/
+
+ This matches either "dog" or "dogsbody", greedily (that is, it prefers
+ the longer string if possible). If it is matched against the string
+ "dog" with PCRE2_PARTIAL_SOFT, it yields a complete match for "dog".
+ However, if PCRE2_PARTIAL_HARD is set, the result is PCRE2_ERROR_PAR-
+ TIAL. On the other hand, if the pattern is made ungreedy the result is
+ different:
+
+ /dog(sbody)??/
+
+ In this case the result is always a complete match because that is
+ found first, and matching never continues after finding a complete
+ match. It might be easier to follow this explanation by thinking of the
+ two patterns like this:
+
+ /dog(sbody)?/ is the same as /dogsbody|dog/
+ /dog(sbody)??/ is the same as /dog|dogsbody/
+
+ The second pattern will never match "dogsbody", because it will always
+ find the shorter match first.
+
+
+PARTIAL MATCHING USING pcre2_dfa_match()
+
+ The DFA functions move along the subject string character by character,
+ without backtracking, searching for all possible matches simultane-
+ ously. If the end of the subject is reached before the end of the pat-
+ tern, there is the possibility of a partial match, again provided that
+ at least one character has been inspected.
+
+ When PCRE2_PARTIAL_SOFT is set, PCRE2_ERROR_PARTIAL is returned only if
+ there have been no complete matches. Otherwise, the complete matches
+ are returned. However, if PCRE2_PARTIAL_HARD is set, a partial match
+ takes precedence over any complete matches. The portion of the string
+ that was matched when the longest partial match was found is set as the
+ first matching string.
+
+ Because the DFA functions always search for all possible matches, and
+ there is no difference between greedy and ungreedy repetition, their
+ behaviour is different from the standard functions when PCRE2_PAR-
+ TIAL_HARD is set. Consider the string "dog" matched against the
+ ungreedy pattern shown above:
+
+ /dog(sbody)??/
+
+ Whereas the standard function stops as soon as it finds the complete
+ match for "dog", the DFA function also finds the partial match for
+ "dogsbody", and so returns that when PCRE2_PARTIAL_HARD is set.
+
+
+PARTIAL MATCHING AND WORD BOUNDARIES
+
+ If a pattern ends with one of sequences \b or \B, which test for word
+ boundaries, partial matching with PCRE2_PARTIAL_SOFT can give counter-
+ intuitive results. Consider this pattern:
+
+ /\bcat\b/
+
+ This matches "cat", provided there is a word boundary at either end. If
+ the subject string is "the cat", the comparison of the final "t" with a
+ following character cannot take place, so a partial match is found.
+ However, normal matching carries on, and \b matches at the end of the
+ subject when the last character is a letter, so a complete match is
+ found. The result, therefore, is not PCRE2_ERROR_PARTIAL. Using
+ PCRE2_PARTIAL_HARD in this case does yield PCRE2_ERROR_PARTIAL, because
+ then the partial match takes precedence.
+
+
+EXAMPLE OF PARTIAL MATCHING USING PCRE2TEST
+
+ If the partial_soft (or ps) modifier is present on a pcre2test data
+ line, the PCRE2_PARTIAL_SOFT option is used for the match. Here is a
+ run of pcre2test that uses the date example quoted above:
+
+ re> /^\d?\d(jan|feb|mar|apr|may|jun|jul|aug|sep|oct|nov|dec)\d\d$/
+ data> 25jun04\=ps
+ 0: 25jun04
+ 1: jun
+ data> 25dec3\=ps
+ Partial match: 23dec3
+ data> 3ju\=ps
+ Partial match: 3ju
+ data> 3juj\=ps
+ No match
+ data> j\=ps
+ No match
+
+ The first data string is matched completely, so pcre2test shows the
+ matched substrings. The remaining four strings do not match the com-
+ plete pattern, but the first two are partial matches. Similar output is
+ obtained if DFA matching is used.
+
+ If the partial_hard (or ph) modifier is present on a pcre2test data
+ line, the PCRE2_PARTIAL_HARD option is set for the match.
+
+
+MULTI-SEGMENT MATCHING WITH pcre2_dfa_match()
+
+ When a partial match has been found using a DFA matching function, it
+ is possible to continue the match by providing additional subject data
+ and calling the function again with the same compiled regular expres-
+ sion, this time setting the PCRE2_DFA_RESTART option. You must pass the
+ same working space as before, because this is where details of the pre-
+ vious partial match are stored. Here is an example using pcre2test:
+
+ re> /^\d?\d(jan|feb|mar|apr|may|jun|jul|aug|sep|oct|nov|dec)\d\d$/
+ data> 23ja\=dfa,ps
+ Partial match: 23ja
+ data> n05\=dfa,dfa_restart
+ 0: n05
+
+ The first call has "23ja" as the subject, and requests partial match-
+ ing; the second call has "n05" as the subject for the continued
+ (restarted) match. Notice that when the match is complete, only the
+ last part is shown; PCRE2 does not retain the previously partially-
+ matched string. It is up to the calling program to do that if it needs
+ to.
+
+ That means that, for an unanchored pattern, if a continued match fails,
+ it is not possible to try again at a new starting point. All this
+ facility is capable of doing is continuing with the previous match
+ attempt. In the previous example, if the second set of data is "ug23"
+ the result is no match, even though there would be a match for "aug23"
+ if the entire string were given at once. Depending on the application,
+ this may or may not be what you want. The only way to allow for start-
+ ing again at the next character is to retain the matched part of the
+ subject and try a new complete match.
+
+ You can set the PCRE2_PARTIAL_SOFT or PCRE2_PARTIAL_HARD options with
+ PCRE2_DFA_RESTART to continue partial matching over multiple segments.
+ This facility can be used to pass very long subject strings to the DFA
+ matching functions.
+
+
+MULTI-SEGMENT MATCHING WITH pcre2_match()
+
+ Unlike the DFA function, it is not possible to restart the previous
+ match with a new segment of data when using pcre2_match(). Instead, new
+ data must be added to the previous subject string, and the entire match
+ re-run, starting from the point where the partial match occurred. Ear-
+ lier data can be discarded.
+
+ It is best to use PCRE2_PARTIAL_HARD in this situation, because it does
+ not treat the end of a segment as the end of the subject when matching
+ \z, \Z, \b, \B, and $. Consider an unanchored pattern that matches
+ dates:
+
+ re> /\d?\d(jan|feb|mar|apr|may|jun|jul|aug|sep|oct|nov|dec)\d\d/
+ data> The date is 23ja\=ph
+ Partial match: 23ja
+
+ At this stage, an application could discard the text preceding "23ja",
+ add on text from the next segment, and call the matching function
+ again. Unlike the DFA matching function, the entire matching string
+ must always be available, and the complete matching process occurs for
+ each call, so more memory and more processing time is needed.
+
+
+ISSUES WITH MULTI-SEGMENT MATCHING
+
+ Certain types of pattern may give problems with multi-segment matching,
+ whichever matching function is used.
+
+ 1. If the pattern contains a test for the beginning of a line, you need
+ to pass the PCRE2_NOTBOL option when the subject string for any call
+ does start at the beginning of a line. There is also a PCRE2_NOTEOL
+ option, but in practice when doing multi-segment matching you should be
+ using PCRE2_PARTIAL_HARD, which includes the effect of PCRE2_NOTEOL.
+
+ 2. If a pattern contains a lookbehind assertion, characters that pre-
+ cede the start of the partial match may have been inspected during the
+ matching process. When using pcre2_match(), sufficient characters must
+ be retained for the next match attempt. You can ensure that enough
+ characters are retained by doing the following:
+
+ Before doing any matching, find the length of the longest lookbehind in
+ the pattern by calling pcre2_pattern_info() with the
+ PCRE2_INFO_MAXLOOKBEHIND option. Note that the resulting count is in
+ characters, not code units. After a partial match, moving back from the
+ ovector[0] offset in the subject by the number of characters given for
+ the maximum lookbehind gets you to the earliest character that must be
+ retained. In a non-UTF or a 32-bit situation, moving back is just a
+ subtraction, but in UTF-8 or UTF-16 you have to count characters while
+ moving back through the code units.
+
+ Characters before the point you have now reached can be discarded, and
+ after the next segment has been added to what is retained, you should
+ run the next match with the startoffset argument set so that the match
+ begins at the same point as before.
+
+ For example, if the pattern "(?<=123)abc" is partially matched against
+ the string "xx123ab", the ovector offsets are 5 and 7 ("ab"). The maxi-
+ mum lookbehind count is 3, so all characters before offset 2 can be
+ discarded. The value of startoffset for the next match should be 3.
+ When pcre2test displays a partial match, it indicates the lookbehind
+ characters with '<' characters:
+
+ re> "(?<=123)abc"
+ data> xx123ab\=ph
+ Partial match: 123ab
+ <<<
+
+ 3. Because a partial match must always contain at least one character,
+ what might be considered a partial match of an empty string actually
+ gives a "no match" result. For example:
+
+ re> /c(?<=abc)x/
+ data> ab\=ps
+ No match
+
+ If the next segment begins "cx", a match should be found, but this will
+ only happen if characters from the previous segment are retained. For
+ this reason, a "no match" result should be interpreted as "partial
+ match of an empty string" when the pattern contains lookbehinds.
+
+ 4. Matching a subject string that is split into multiple segments may
+ not always produce exactly the same result as matching over one single
+ long string, especially when PCRE2_PARTIAL_SOFT is used. The section
+ "Partial Matching and Word Boundaries" above describes an issue that
+ arises if the pattern ends with \b or \B. Another kind of difference
+ may occur when there are multiple matching possibilities, because (for
+ PCRE2_PARTIAL_SOFT) a partial match result is given only when there are
+ no completed matches. This means that as soon as the shortest match has
+ been found, continuation to a new subject segment is no longer possi-
+ ble. Consider this pcre2test example:
+
+ re> /dog(sbody)?/
+ data> dogsb\=ps
+ 0: dog
+ data> do\=ps,dfa
+ Partial match: do
+ data> gsb\=ps,dfa,dfa_restart
+ 0: g
+ data> dogsbody\=dfa
+ 0: dogsbody
+ 1: dog
+
+ The first data line passes the string "dogsb" to a standard matching
+ function, setting the PCRE2_PARTIAL_SOFT option. Although the string is
+ a partial match for "dogsbody", the result is not PCRE2_ERROR_PARTIAL,
+ because the shorter string "dog" is a complete match. Similarly, when
+ the subject is presented to a DFA matching function in several parts
+ ("do" and "gsb" being the first two) the match stops when "dog" has
+ been found, and it is not possible to continue. On the other hand, if
+ "dogsbody" is presented as a single string, a DFA matching function
+ finds both matches.
+
+ Because of these problems, it is best to use PCRE2_PARTIAL_HARD when
+ matching multi-segment data. The example above then behaves differ-
+ ently:
+
+ re> /dog(sbody)?/
+ data> dogsb\=ph
+ Partial match: dogsb
+ data> do\=ps,dfa
+ Partial match: do
+ data> gsb\=ph,dfa,dfa_restart
+ Partial match: gsb
+
+ 5. Patterns that contain alternatives at the top level which do not all
+ start with the same pattern item may not work as expected when
+ PCRE2_DFA_RESTART is used. For example, consider this pattern:
+
+ 1234|3789
+
+ If the first part of the subject is "ABC123", a partial match of the
+ first alternative is found at offset 3. There is no partial match for
+ the second alternative, because such a match does not start at the same
+ point in the subject string. Attempting to continue with the string
+ "7890" does not yield a match because only those alternatives that
+ match at one point in the subject are remembered. The problem arises
+ because the start of the second alternative matches within the first
+ alternative. There is no problem with anchored patterns or patterns
+ such as:
+
+ 1234|ABCD
+
+ where no string can be a partial match for both alternatives. This is
+ not a problem if a standard matching function is used, because the
+ entire match has to be rerun each time:
+
+ re> /1234|3789/
+ data> ABC123\=ph
+ Partial match: 123
+ data> 1237890
+ 0: 3789
+
+ Of course, instead of using PCRE2_DFA_RESTART, the same technique of
+ re-running the entire match can also be used with the DFA matching
+ function. Another possibility is to work with two buffers. If a partial
+ match at offset n in the first buffer is followed by "no match" when
+ PCRE2_DFA_RESTART is used on the second buffer, you can then try a new
+ match starting at offset n+1 in the first buffer.

+NAME
+ PCRE2 - Perl-compatible regular expressions (revised API)
+
+PCRE2 REGULAR EXPRESSION DETAILS
+
+ The syntax and semantics of the regular expressions that are supported
+ by PCRE2 are described in detail below. There is a quick-reference syn-
+ tax summary in the pcre2syntax page. PCRE2 tries to match Perl syntax
+ and semantics as closely as it can. PCRE2 also supports some alterna-
+ tive regular expression syntax (which does not conflict with the Perl
+ syntax) in order to provide some compatibility with regular expressions
+ in Python, .NET, and Oniguruma.
+
+ Perl's regular expressions are described in its own documentation, and
+ regular expressions in general are covered in a number of books, some
+ of which have copious examples. Jeffrey Friedl's "Mastering Regular
+ Expressions", published by O'Reilly, covers regular expressions in
+ great detail. This description of PCRE2's regular expressions is
+ intended as reference material.
+
+ This document discusses the patterns that are supported by PCRE2 when
+ its main matching function, pcre2_match(), is used. PCRE2 also has an
+ alternative matching function, pcre2_dfa_match(), which matches using a
+ different algorithm that is not Perl-compatible. Some of the features
+ discussed below are not available when DFA matching is used. The advan-
+ tages and disadvantages of the alternative function, and how it differs
+ from the normal function, are discussed in the pcre2matching page.
+
+
+SPECIAL START-OF-PATTERN ITEMS
+
+ A number of options that can be passed to pcre2_compile() can also be
+ set by special items at the start of a pattern. These are not Perl-com-
+ patible, but are provided to make these options accessible to pattern
+ writers who are not able to change the program that processes the pat-
+ tern. Any number of these items may appear, but they must all be
+ together right at the start of the pattern string, and the letters must
+ be in upper case.
+
+ UTF support
+
+ In the 8-bit and 16-bit PCRE2 libraries, characters may be coded either
+ as single code units, or as multiple UTF-8 or UTF-16 code units. UTF-32
+ can be specified for the 32-bit library, in which case it constrains
+ the character values to valid Unicode code points. To process UTF
+ strings, PCRE2 must be built to include Unicode support (which is the
+ default). When using UTF strings you must either call the compiling
+ function with the PCRE2_UTF option, or the pattern must start with the
+ special sequence (*UTF), which is equivalent to setting the relevant
+ option. How setting a UTF mode affects pattern matching is mentioned in
+ several places below. There is also a summary of features in the
+ pcre2unicode page.
+
+ Some applications that allow their users to supply patterns may wish to
+ restrict them to non-UTF data for security reasons. If the
+ PCRE2_NEVER_UTF option is passed to pcre2_compile(), (*UTF) is not
+ allowed, and its appearance in a pattern causes an error.
+
+ Unicode property support
+
+ Another special sequence that may appear at the start of a pattern is
+ (*UCP). This has the same effect as setting the PCRE2_UCP option: it
+ causes sequences such as \d and \w to use Unicode properties to deter-
+ mine character types, instead of recognizing only characters with codes
+ less than 256 via a lookup table.
+
+ Some applications that allow their users to supply patterns may wish to
+ restrict them for security reasons. If the PCRE2_NEVER_UCP option is
+ passed to pcre2_compile(), (*UCP) is not allowed, and its appearance in
+ a pattern causes an error.
+
+ Locking out empty string matching
+
+ Starting a pattern with (*NOTEMPTY) or (*NOTEMPTY_ATSTART) has the same
+ effect as passing the PCRE2_NOTEMPTY or PCRE2_NOTEMPTY_ATSTART option
+ to whichever matching function is subsequently called to match the pat-
+ tern. These options lock out the matching of empty strings, either
+ entirely, or only at the start of the subject.
+
+ Disabling auto-possessification
+
+ If a pattern starts with (*NO_AUTO_POSSESS), it has the same effect as
+ setting the PCRE2_NO_AUTO_POSSESS option. This stops PCRE2 from making
+ quantifiers possessive when what follows cannot match the repeated
+ item. For example, by default a+b is treated as a++b. For more details,
+ see the pcre2api documentation.
+
+ Disabling start-up optimizations
+
+ If a pattern starts with (*NO_START_OPT), it has the same effect as
+ setting the PCRE2_NO_START_OPTIMIZE option. This disables several opti-
+ mizations for quickly reaching "no match" results. For more details,
+ see the pcre2api documentation.
+
+ Disabling automatic anchoring
+
+ If a pattern starts with (*NO_DOTSTAR_ANCHOR), it has the same effect
+ as setting the PCRE2_NO_DOTSTAR_ANCHOR option. This disables optimiza-
+ tions that apply to patterns whose top-level branches all start with .*
+ (match any number of arbitrary characters). For more details, see the
+ pcre2api documentation.
+
+ Disabling JIT compilation
+
+ If a pattern that starts with (*NO_JIT) is successfully compiled, an
+ attempt by the application to apply the JIT optimization by calling
+ pcre2_jit_compile() is ignored.
+
+ Setting match and recursion limits
+
+ The caller of pcre2_match() can set a limit on the number of times the
+ internal match() function is called and on the maximum depth of recur-
+ sive calls. These facilities are provided to catch runaway matches that
+ are provoked by patterns with huge matching trees (a typical example is
+ a pattern with nested unlimited repeats) and to avoid running out of
+ system stack by too much recursion. When one of these limits is
+ reached, pcre2_match() gives an error return. The limits can also be
+ set by items at the start of the pattern of the form
+
+ (*LIMIT_MATCH=d)
+ (*LIMIT_RECURSION=d)
+
+ where d is any number of decimal digits. However, the value of the set-
+ ting must be less than the value set (or defaulted) by the caller of
+ pcre2_match() for it to have any effect. In other words, the pattern
+ writer can lower the limits set by the programmer, but not raise them.
+ If there is more than one setting of one of these limits, the lower
+ value is used.
+
+ Newline conventions
+
+ PCRE2 supports five different conventions for indicating line breaks in
+ strings: a single CR (carriage return) character, a single LF (line-
+ feed) character, the two-character sequence CRLF, any of the three pre-
+ ceding, or any Unicode newline sequence. The pcre2api page has further
+ discussion about newlines, and shows how to set the newline convention
+ when calling pcre2_compile().
+
+ It is also possible to specify a newline convention by starting a pat-
+ tern string with one of the following five sequences:
+
+ (*CR) carriage return
+ (*LF) linefeed
+ (*CRLF) carriage return, followed by linefeed
+ (*ANYCRLF) any of the three above
+ (*ANY) all Unicode newline sequences
+
+ These override the default and the options given to the compiling func-
+ tion. For example, on a Unix system where LF is the default newline
+ sequence, the pattern
+
+ (*CR)a.b
+
+ changes the convention to CR. That pattern matches "a\nb" because LF is
+ no longer a newline. If more than one of these settings is present, the
+ last one is used.
+
+ The newline convention affects where the circumflex and dollar asser-
+ tions are true. It also affects the interpretation of the dot metachar-
+ acter when PCRE2_DOTALL is not set, and the behaviour of \N. However,
+ it does not affect what the \R escape sequence matches. By default,
+ this is any Unicode newline sequence, for Perl compatibility. However,
+ this can be changed; see the description of \R in the section entitled
+ "Newline sequences" below. A change of \R setting can be combined with
+ a change of newline convention.
+
+ Specifying what \R matches
+
+ It is possible to restrict \R to match only CR, LF, or CRLF (instead of
+ the complete set of Unicode line endings) by setting the option
+ PCRE2_BSR_ANYCRLF at compile time. This effect can also be achieved by
+ starting a pattern with (*BSR_ANYCRLF). For completeness, (*BSR_UNI-
+ CODE) is also recognized, corresponding to PCRE2_BSR_UNICODE.
+
+
+EBCDIC CHARACTER CODES
+
+ PCRE2 can be compiled to run in an environment that uses EBCDIC as its
+ character code rather than ASCII or Unicode (typically a mainframe sys-
+ tem). In the sections below, character code values are ASCII or Uni-
+ code; in an EBCDIC environment these characters may have different code
+ values, and there are no code points greater than 255.
+
+
+CHARACTERS AND METACHARACTERS
+
+ A regular expression is a pattern that is matched against a subject
+ string from left to right. Most characters stand for themselves in a
+ pattern, and match the corresponding characters in the subject. As a
+ trivial example, the pattern
+
+ The quick brown fox
+
+ matches a portion of a subject string that is identical to itself. When
+ caseless matching is specified (the PCRE2_CASELESS option), letters are
+ matched independently of case.
+
+ The power of regular expressions comes from the ability to include
+ alternatives and repetitions in the pattern. These are encoded in the
+ pattern by the use of metacharacters, which do not stand for themselves
+ but instead are interpreted in some special way.
+
+ There are two different sets of metacharacters: those that are recog-
+ nized anywhere in the pattern except within square brackets, and those
+ that are recognized within square brackets. Outside square brackets,
+ the metacharacters are as follows:
+
+ \ general escape character with several uses
+ ^ assert start of string (or line, in multiline mode)
+ $ assert end of string (or line, in multiline mode)
+ . match any character except newline (by default)
+ [ start character class definition
+ | start of alternative branch
+ ( start subpattern
+ ) end subpattern
+ ? extends the meaning of (
+ also 0 or 1 quantifier
+ also quantifier minimizer
+ * 0 or more quantifier
+ + 1 or more quantifier
+ also "possessive quantifier"
+ { start min/max quantifier
+
+ Part of a pattern that is in square brackets is called a "character
+ class". In a character class the only metacharacters are:
+
+ \ general escape character
+ ^ negate the class, but only if the first character
+ - indicates character range
+ [ POSIX character class (only if followed by POSIX
+ syntax)
+ ] terminates the character class
+
+ The following sections describe the use of each of the metacharacters.
+
+
+BACKSLASH
+
+ The backslash character has several uses. Firstly, if it is followed by
+ a character that is not a number or a letter, it takes away any special
+ meaning that character may have. This use of backslash as an escape
+ character applies both inside and outside character classes.
+
+ For example, if you want to match a * character, you write \* in the
+ pattern. This escaping action applies whether or not the following
+ character would otherwise be interpreted as a metacharacter, so it is
+ always safe to precede a non-alphanumeric with backslash to specify
+ that it stands for itself. In particular, if you want to match a back-
+ slash, you write \\.
+
+ In a UTF mode, only ASCII numbers and letters have any special meaning
+ after a backslash. All other characters (in particular, those whose
+ codepoints are greater than 127) are treated as literals.
+
+ If a pattern is compiled with the PCRE2_EXTENDED option, most white
+ space in the pattern (other than in a character class), and characters
+ between a # outside a character class and the next newline, inclusive,
+ are ignored. An escaping backslash can be used to include a white space
+ or # character as part of the pattern.
+
+ If you want to remove the special meaning from a sequence of charac-
+ ters, you can do so by putting them between \Q and \E. This is differ-
+ ent from Perl in that $ and @ are handled as literals in \Q...\E
+ sequences in PCRE2, whereas in Perl, $ and @ cause variable interpola-
+ tion. Note the following examples:
+
+ Pattern PCRE2 matches Perl matches
+
+ \Qabc$xyz\E abc$xyz abc followed by the
+ contents of $xyz
+ \Qabc\$xyz\E abc\$xyz abc\$xyz
+ \Qabc\E\$\Qxyz\E abc$xyz abc$xyz
+
+ The \Q...\E sequence is recognized both inside and outside character
+ classes. An isolated \E that is not preceded by \Q is ignored. If \Q
+ is not followed by \E later in the pattern, the literal interpretation
+ continues to the end of the pattern (that is, \E is assumed at the
+ end). If the isolated \Q is inside a character class, this causes an
+ error, because the character class is not terminated.
+
+ Non-printing characters
+
+ A second use of backslash provides a way of encoding non-printing char-
+ acters in patterns in a visible manner. There is no restriction on the
+ appearance of non-printing characters in a pattern, but when a pattern
+ is being prepared by text editing, it is often easier to use one of the
+ following escape sequences than the binary character it represents. In
+ an ASCII or Unicode environment, these escapes are as follows:
+
+ \a alarm, that is, the BEL character (hex 07)
+ \cx "control-x", where x is any printable ASCII character
+ \e escape (hex 1B)
+ \f form feed (hex 0C)
+ \n linefeed (hex 0A)
+ \r carriage return (hex 0D)
+ \t tab (hex 09)
+ \0dd character with octal code 0dd
+ \ddd character with octal code ddd, or back reference
+ \o{ddd..} character with octal code ddd..
+ \xhh character with hex code hh
+ \x{hhh..} character with hex code hhh.. (default mode)
+ \uhhhh character with hex code hhhh (when PCRE2_ALT_BSUX is set)
+
+ The precise effect of \cx on ASCII characters is as follows: if x is a
+ lower case letter, it is converted to upper case. Then bit 6 of the
+ character (hex 40) is inverted. Thus \cA to \cZ become hex 01 to hex 1A
+ (A is 41, Z is 5A), but \c{ becomes hex 3B ({ is 7B), and \c; becomes
+ hex 7B (; is 3B). If the code unit following \c has a value less than
+ 32 or greater than 126, a compile-time error occurs. This locks out
+ non-printable ASCII characters in all modes.
+
+ When PCRE2 is compiled in EBCDIC mode, \a, \e, \f, \n, \r, and \t gen-
+ erate the appropriate EBCDIC code values. The \c escape is processed as
+ specified for Perl in the perlebcdic document. The only characters that
+ are allowed after \c are A-Z, a-z, or one of @, [, \, ], ^, _, or ?.
+ Any other character provokes a compile-time error. The sequence \@
+ encodes character code 0; the letters (in either case) encode charac-
+ ters 1-26 (hex 01 to hex 1A); [, \, ], ^, and _ encode characters 27-31
+ (hex 1B to hex 1F), and \? becomes either 255 (hex FF) or 95 (hex 5F).
+
+ Thus, apart from \?, these escapes generate the same character code
+ values as they do in an ASCII environment, though the meanings of the
+ values mostly differ. For example, \G always generates code value 7,
+ which is BEL in ASCII but DEL in EBCDIC.
+
+ The sequence \? generates DEL (127, hex 7F) in an ASCII environment,
+ but because 127 is not a control character in EBCDIC, Perl makes it
+ generate the APC character. Unfortunately, there are several variants
+ of EBCDIC. In most of them the APC character has the value 255 (hex
+ FF), but in the one Perl calls POSIX-BC its value is 95 (hex 5F). If
+ certain other characters have POSIX-BC values, PCRE2 makes \? generate
+ 95; otherwise it generates 255.
+
+ After \0 up to two further octal digits are read. If there are fewer
+ than two digits, just those that are present are used. Thus the
+ sequence \0\x\015 specifies two binary zeros followed by a CR character
+ (code value 13). Make sure you supply two digits after the initial zero
+ if the pattern character that follows is itself an octal digit.
+
+ The escape \o must be followed by a sequence of octal digits, enclosed
+ in braces. An error occurs if this is not the case. This escape is a
+ recent addition to Perl; it provides way of specifying character code
+ points as octal numbers greater than 0777, and it also allows octal
+ numbers and back references to be unambiguously specified.
+
+ For greater clarity and unambiguity, it is best to avoid following \ by
+ a digit greater than zero. Instead, use \o{} or \x{} to specify charac-
+ ter numbers, and \g{} to specify back references. The following para-
+ graphs describe the old, ambiguous syntax.
+
+ The handling of a backslash followed by a digit other than 0 is compli-
+ cated, and Perl has changed over time, causing PCRE2 also to change.
+
+ Outside a character class, PCRE2 reads the digit and any following dig-
+ its as a decimal number. If the number is less than 10, begins with the
+ digit 8 or 9, or if there are at least that many previous capturing
+ left parentheses in the expression, the entire sequence is taken as a
+ back reference. A description of how this works is given later, follow-
+ ing the discussion of parenthesized subpatterns. Otherwise, up to
+ three octal digits are read to form a character code.
+
+ Inside a character class, PCRE2 handles \8 and \9 as the literal char-
+ acters "8" and "9", and otherwise reads up to three octal digits fol-
+ lowing the backslash, using them to generate a data character. Any sub-
+ sequent digits stand for themselves. For example, outside a character
+ class:
+
+ \040 is another way of writing an ASCII space
+ \40 is the same, provided there are fewer than 40
+ previous capturing subpatterns
+ \7 is always a back reference
+ \11 might be a back reference, or another way of
+ writing a tab
+ \011 is always a tab
+ \0113 is a tab followed by the character "3"
+ \113 might be a back reference, otherwise the
+ character with octal code 113
+ \377 might be a back reference, otherwise
+ the value 255 (decimal)
+ \81 is always a back reference
+
+ Note that octal values of 100 or greater that are specified using this
+ syntax must not be introduced by a leading zero, because no more than
+ three octal digits are ever read.
+
+ By default, after \x that is not followed by {, from zero to two hexa-
+ decimal digits are read (letters can be in upper or lower case). Any
+ number of hexadecimal digits may appear between \x{ and }. If a charac-
+ ter other than a hexadecimal digit appears between \x{ and }, or if
+ there is no terminating }, an error occurs.
+
+ If the PCRE2_ALT_BSUX option is set, the interpretation of \x is as
+ just described only when it is followed by two hexadecimal digits. Oth-
+ erwise, it matches a literal "x" character. In this mode mode, support
+ for code points greater than 256 is provided by \u, which must be fol-
+ lowed by four hexadecimal digits; otherwise it matches a literal "u"
+ character.
+
+ Characters whose value is less than 256 can be defined by either of the
+ two syntaxes for \x (or by \u in PCRE2_ALT_BSUX mode). There is no dif-
+ ference in the way they are handled. For example, \xdc is exactly the
+ same as \x{dc} (or \u00dc in PCRE2_ALT_BSUX mode).
+
+ Constraints on character values
+
+ Characters that are specified using octal or hexadecimal numbers are
+ limited to certain values, as follows:
+
+ 8-bit non-UTF mode less than 0x100
+ 8-bit UTF-8 mode less than 0x10ffff and a valid codepoint
+ 16-bit non-UTF mode less than 0x10000
+ 16-bit UTF-16 mode less than 0x10ffff and a valid codepoint
+ 32-bit non-UTF mode less than 0x100000000
+ 32-bit UTF-32 mode less than 0x10ffff and a valid codepoint
+
+ Invalid Unicode codepoints are the range 0xd800 to 0xdfff (the so-
+ called "surrogate" codepoints), and 0xffef.
+
+ Escape sequences in character classes
+
+ All the sequences that define a single character value can be used both
+ inside and outside character classes. In addition, inside a character
+ class, \b is interpreted as the backspace character (hex 08).
+
+ \N is not allowed in a character class. \B, \R, and \X are not special
+ inside a character class. Like other unrecognized alphabetic escape
+ sequences, they cause an error. Outside a character class, these
+ sequences have different meanings.
+
+ Unsupported escape sequences
+
+ In Perl, the sequences \l, \L, \u, and \U are recognized by its string
+ handler and used to modify the case of following characters. By
+ default, PCRE2 does not support these escape sequences. However, if the
+ PCRE2_ALT_BSUX option is set, \U matches a "U" character, and \u can be
+ used to define a character by code point, as described in the previous
+ section.
+
+ Absolute and relative back references
+
+ The sequence \g followed by an unsigned or a negative number, option-
+ ally enclosed in braces, is an absolute or relative back reference. A
+ named back reference can be coded as \g{name}. Back references are dis-
+ cussed later, following the discussion of parenthesized subpatterns.
+
+ Absolute and relative subroutine calls
+
+ For compatibility with Oniguruma, the non-Perl syntax \g followed by a
+ name or a number enclosed either in angle brackets or single quotes, is
+ an alternative syntax for referencing a subpattern as a "subroutine".
+ Details are discussed later. Note that \g{...} (Perl syntax) and
+ \g<...> (Oniguruma syntax) are not synonymous. The former is a back
+ reference; the latter is a subroutine call.
+
+ Generic character types
+
+ Another use of backslash is for specifying generic character types:
+
+ \d any decimal digit
+ \D any character that is not a decimal digit
+ \h any horizontal white space character
+ \H any character that is not a horizontal white space character
+ \s any white space character
+ \S any character that is not a white space character
+ \v any vertical white space character
+ \V any character that is not a vertical white space character
+ \w any "word" character
+ \W any "non-word" character
+
+ There is also the single sequence \N, which matches a non-newline char-
+ acter. This is the same as the "." metacharacter when PCRE2_DOTALL is
+ not set. Perl also uses \N to match characters by name; PCRE2 does not
+ support this.
+
+ Each pair of lower and upper case escape sequences partitions the com-
+ plete set of characters into two disjoint sets. Any given character
+ matches one, and only one, of each pair. The sequences can appear both
+ inside and outside character classes. They each match one character of
+ the appropriate type. If the current matching point is at the end of
+ the subject string, all of them fail, because there is no character to
+ match.
+
+ The default \s characters are HT (9), LF (10), VT (11), FF (12), CR
+ (13), and space (32), which are defined as white space in the "C"
+ locale. This list may vary if locale-specific matching is taking place.
+ For example, in some locales the "non-breaking space" character (\xA0)
+ is recognized as white space, and in others the VT character is not.
+
+ A "word" character is an underscore or any character that is a letter
+ or digit. By default, the definition of letters and digits is con-
+ trolled by PCRE2's low-valued character tables, and may vary if locale-
+ specific matching is taking place (see "Locale support" in the pcre2api
+ page). For example, in a French locale such as "fr_FR" in Unix-like
+ systems, or "french" in Windows, some character codes greater than 127
+ are used for accented letters, and these are then matched by \w. The
+ use of locales with Unicode is discouraged.
+
+ By default, characters whose code points are greater than 127 never
+ match \d, \s, or \w, and always match \D, \S, and \W, although this may
+ be different for characters in the range 128-255 when locale-specific
+ matching is happening. These escape sequences retain their original
+ meanings from before Unicode support was available, mainly for effi-
+ ciency reasons. If the PCRE2_UCP option is set, the behaviour is
+ changed so that Unicode properties are used to determine character
+ types, as follows:
+
+ \d any character that matches \p{Nd} (decimal digit)
+ \s any character that matches \p{Z} or \h or \v
+ \w any character that matches \p{L} or \p{N}, plus underscore
+
+ The upper case escapes match the inverse sets of characters. Note that
+ \d matches only decimal digits, whereas \w matches any Unicode digit,
+ as well as any Unicode letter, and underscore. Note also that PCRE2_UCP
+ affects \b, and \B because they are defined in terms of \w and \W.
+ Matching these sequences is noticeably slower when PCRE2_UCP is set.
+
+ The sequences \h, \H, \v, and \V, in contrast to the other sequences,
+ which match only ASCII characters by default, always match a specific
+ list of code points, whether or not PCRE2_UCP is set. The horizontal
+ space characters are:
+
+ U+0009 Horizontal tab (HT)
+ U+0020 Space
+ U+00A0 Non-break space
+ U+1680 Ogham space mark
+ U+180E Mongolian vowel separator
+ U+2000 En quad
+ U+2001 Em quad
+ U+2002 En space
+ U+2003 Em space
+ U+2004 Three-per-em space
+ U+2005 Four-per-em space
+ U+2006 Six-per-em space
+ U+2007 Figure space
+ U+2008 Punctuation space
+ U+2009 Thin space
+ U+200A Hair space
+ U+202F Narrow no-break space
+ U+205F Medium mathematical space
+ U+3000 Ideographic space
+
+ The vertical space characters are:
+
+ U+000A Linefeed (LF)
+ U+000B Vertical tab (VT)
+ U+000C Form feed (FF)
+ U+000D Carriage return (CR)
+ U+0085 Next line (NEL)
+ U+2028 Line separator
+ U+2029 Paragraph separator
+
+ In 8-bit, non-UTF-8 mode, only the characters with code points less
+ than 256 are relevant.
+
+ Newline sequences
+
+ Outside a character class, by default, the escape sequence \R matches
+ any Unicode newline sequence. In 8-bit non-UTF-8 mode \R is equivalent
+ to the following:
+
+ (?>\r\n|\n|\x0b|\f|\r|\x85)
+
+ This is an example of an "atomic group", details of which are given
+ below. This particular group matches either the two-character sequence
+ CR followed by LF, or one of the single characters LF (linefeed,
+ U+000A), VT (vertical tab, U+000B), FF (form feed, U+000C), CR (car-
+ riage return, U+000D), or NEL (next line, U+0085). Because this is an
+ atomic group, the two-character sequence is treated as a single unit
+ that cannot be split.
+
+ In other modes, two additional characters whose codepoints are greater
+ than 255 are added: LS (line separator, U+2028) and PS (paragraph sepa-
+ rator, U+2029). Unicode support is not needed for these characters to
+ be recognized.
+
+ It is possible to restrict \R to match only CR, LF, or CRLF (instead of
+ the complete set of Unicode line endings) by setting the option
+ PCRE2_BSR_ANYCRLF at compile time. (BSR is an abbrevation for "back-
+ slash R".) This can be made the default when PCRE2 is built; if this is
+ the case, the other behaviour can be requested via the PCRE2_BSR_UNI-
+ CODE option. It is also possible to specify these settings by starting
+ a pattern string with one of the following sequences:
+
+ (*BSR_ANYCRLF) CR, LF, or CRLF only
+ (*BSR_UNICODE) any Unicode newline sequence
+
+ These override the default and the options given to the compiling func-
+ tion. Note that these special settings, which are not Perl-compatible,
+ are recognized only at the very start of a pattern, and that they must
+ be in upper case. If more than one of them is present, the last one is
+ used. They can be combined with a change of newline convention; for
+ example, a pattern can start with:
+
+ (*ANY)(*BSR_ANYCRLF)
+
+ They can also be combined with the (*UTF) or (*UCP) special sequences.
+ Inside a character class, \R is treated as an unrecognized escape
+ sequence, and causes an error.
+
+ Unicode character properties
+
+ When PCRE2 is built with Unicode support (the default), three addi-
+ tional escape sequences that match characters with specific properties
+ are available. In 8-bit non-UTF-8 mode, these sequences are of course
+ limited to testing characters whose codepoints are less than 256, but
+ they do work in this mode. The extra escape sequences are:
+
+ \p{xx} a character with the xx property
+ \P{xx} a character without the xx property
+ \X a Unicode extended grapheme cluster
+
+ The property names represented by xx above are limited to the Unicode
+ script names, the general category properties, "Any", which matches any
+ character (including newline), and some special PCRE2 properties
+ (described in the next section). Other Perl properties such as "InMu-
+ sicalSymbols" are not supported by PCRE2. Note that \P{Any} does not
+ match any characters, so always causes a match failure.
+
+ Sets of Unicode characters are defined as belonging to certain scripts.
+ A character from one of these sets can be matched using a script name.
+ For example:
+
+ \p{Greek}
+ \P{Han}
+
+ Those that are not part of an identified script are lumped together as
+ "Common". The current list of scripts is:
+
+ Ahom, Anatolian_Hieroglyphs, Arabic, Armenian, Avestan, Balinese,
+ Bamum, Bassa_Vah, Batak, Bengali, Bopomofo, Brahmi, Braille, Buginese,
+ Buhid, Canadian_Aboriginal, Carian, Caucasian_Albanian, Chakma, Cham,
+ Cherokee, Common, Coptic, Cuneiform, Cypriot, Cyrillic, Deseret,
+ Devanagari, Duployan, Egyptian_Hieroglyphs, Elbasan, Ethiopic, Geor-
+ gian, Glagolitic, Gothic, Grantha, Greek, Gujarati, Gurmukhi, Han,
+ Hangul, Hanunoo, Hatran, Hebrew, Hiragana, Imperial_Aramaic, Inherited,
+ Inscriptional_Pahlavi, Inscriptional_Parthian, Javanese, Kaithi, Kan-
+ nada, Katakana, Kayah_Li, Kharoshthi, Khmer, Khojki, Khudawadi, Lao,
+ Latin, Lepcha, Limbu, Linear_A, Linear_B, Lisu, Lycian, Lydian, Maha-
+ jani, Malayalam, Mandaic, Manichaean, Meetei_Mayek, Mende_Kikakui,
+ Meroitic_Cursive, Meroitic_Hieroglyphs, Miao, Modi, Mongolian, Mro,
+ Multani, Myanmar, Nabataean, New_Tai_Lue, Nko, Ogham, Ol_Chiki,
+ Old_Hungarian, Old_Italic, Old_North_Arabian, Old_Permic, Old_Persian,
+ Old_South_Arabian, Old_Turkic, Oriya, Osmanya, Pahawh_Hmong, Palmyrene,
+ Pau_Cin_Hau, Phags_Pa, Phoenician, Psalter_Pahlavi, Rejang, Runic,
+ Samaritan, Saurashtra, Sharada, Shavian, Siddham, SignWriting, Sinhala,
+ Sora_Sompeng, Sundanese, Syloti_Nagri, Syriac, Tagalog, Tagbanwa,
+ Tai_Le, Tai_Tham, Tai_Viet, Takri, Tamil, Telugu, Thaana, Thai,
+ Tibetan, Tifinagh, Tirhuta, Ugaritic, Vai, Warang_Citi, Yi.
+
+ Each character has exactly one Unicode general category property, spec-
+ ified by a two-letter abbreviation. For compatibility with Perl, nega-
+ tion can be specified by including a circumflex between the opening
+ brace and the property name. For example, \p{^Lu} is the same as
+ \P{Lu}.
+
+ If only one letter is specified with \p or \P, it includes all the gen-
+ eral category properties that start with that letter. In this case, in
+ the absence of negation, the curly brackets in the escape sequence are
+ optional; these two examples have the same effect:
+
+ \p{L}
+ \pL
+
+ The following general category property codes are supported:
+
+ C Other
+ Cc Control
+ Cf Format
+ Cn Unassigned
+ Co Private use
+ Cs Surrogate
+
+ L Letter
+ Ll Lower case letter
+ Lm Modifier letter
+ Lo Other letter
+ Lt Title case letter
+ Lu Upper case letter
+
+ M Mark
+ Mc Spacing mark
+ Me Enclosing mark
+ Mn Non-spacing mark
+
+ N Number
+ Nd Decimal number
+ Nl Letter number
+ No Other number
+
+ P Punctuation
+ Pc Connector punctuation
+ Pd Dash punctuation
+ Pe Close punctuation
+ Pf Final punctuation
+ Pi Initial punctuation
+ Po Other punctuation
+ Ps Open punctuation
+
+ S Symbol
+ Sc Currency symbol
+ Sk Modifier symbol
+ Sm Mathematical symbol
+ So Other symbol
+
+ Z Separator
+ Zl Line separator
+ Zp Paragraph separator
+ Zs Space separator
+
+ The special property L& is also supported: it matches a character that
+ has the Lu, Ll, or Lt property, in other words, a letter that is not
+ classified as a modifier or "other".
+
+ The Cs (Surrogate) property applies only to characters in the range
+ U+D800 to U+DFFF. Such characters are not valid in Unicode strings and
+ so cannot be tested by PCRE2, unless UTF validity checking has been
+ turned off (see the discussion of PCRE2_NO_UTF_CHECK in the pcre2api
+ page). Perl does not support the Cs property.
+
+ The long synonyms for property names that Perl supports (such as
+ \p{Letter}) are not supported by PCRE2, nor is it permitted to prefix
+ any of these properties with "Is".
+
+ No character that is in the Unicode table has the Cn (unassigned) prop-
+ erty. Instead, this property is assumed for any code point that is not
+ in the Unicode table.
+
+ Specifying caseless matching does not affect these escape sequences.
+ For example, \p{Lu} always matches only upper case letters. This is
+ different from the behaviour of current versions of Perl.
+
+ Matching characters by Unicode property is not fast, because PCRE2 has
+ to do a multistage table lookup in order to find a character's prop-
+ erty. That is why the traditional escape sequences such as \d and \w do
+ not use Unicode properties in PCRE2 by default, though you can make
+ them do so by setting the PCRE2_UCP option or by starting the pattern
+ with (*UCP).
+
+ Extended grapheme clusters
+
+ The \X escape matches any number of Unicode characters that form an
+ "extended grapheme cluster", and treats the sequence as an atomic group
+ (see below). Unicode supports various kinds of composite character by
+ giving each character a grapheme breaking property, and having rules
+ that use these properties to define the boundaries of extended grapheme
+ clusters. \X always matches at least one character. Then it decides
+ whether to add additional characters according to the following rules
+ for ending a cluster:
+
+ 1. End at the end of the subject string.
+
+ 2. Do not end between CR and LF; otherwise end after any control char-
+ acter.
+
+ 3. Do not break Hangul (a Korean script) syllable sequences. Hangul
+ characters are of five types: L, V, T, LV, and LVT. An L character may
+ be followed by an L, V, LV, or LVT character; an LV or V character may
+ be followed by a V or T character; an LVT or T character may be follwed
+ only by a T character.
+
+ 4. Do not end before extending characters or spacing marks. Characters
+ with the "mark" property always have the "extend" grapheme breaking
+ property.
+
+ 5. Do not end after prepend characters.
+
+ 6. Otherwise, end the cluster.
+
+ PCRE2's additional properties
+
+ As well as the standard Unicode properties described above, PCRE2 sup-
+ ports four more that make it possible to convert traditional escape
+ sequences such as \w and \s to use Unicode properties. PCRE2 uses these
+ non-standard, non-Perl properties internally when PCRE2_UCP is set.
+ However, they may also be used explicitly. These properties are:
+
+ Xan Any alphanumeric character
+ Xps Any POSIX space character
+ Xsp Any Perl space character
+ Xwd Any Perl "word" character
+
+ Xan matches characters that have either the L (letter) or the N (num-
+ ber) property. Xps matches the characters tab, linefeed, vertical tab,
+ form feed, or carriage return, and any other character that has the Z
+ (separator) property. Xsp is the same as Xps; in PCRE1 it used to
+ exclude vertical tab, for Perl compatibility, but Perl changed. Xwd
+ matches the same characters as Xan, plus underscore.
+
+ There is another non-standard property, Xuc, which matches any charac-
+ ter that can be represented by a Universal Character Name in C++ and
+ other programming languages. These are the characters $, @, ` (grave
+ accent), and all characters with Unicode code points greater than or
+ equal to U+00A0, except for the surrogates U+D800 to U+DFFF. Note that
+ most base (ASCII) characters are excluded. (Universal Character Names
+ are of the form \uHHHH or \UHHHHHHHH where H is a hexadecimal digit.
+ Note that the Xuc property does not match these sequences but the char-
+ acters that they represent.)
+
+ Resetting the match start
+
+ The escape sequence \K causes any previously matched characters not to
+ be included in the final matched sequence. For example, the pattern:
+
+ foo\Kbar
+
+ matches "foobar", but reports that it has matched "bar". This feature
+ is similar to a lookbehind assertion (described below). However, in
+ this case, the part of the subject before the real match does not have
+ to be of fixed length, as lookbehind assertions do. The use of \K does
+ not interfere with the setting of captured substrings. For example,
+ when the pattern
+
+ (foo)\Kbar
+
+ matches "foobar", the first substring is still set to "foo".
+
+ Perl documents that the use of \K within assertions is "not well
+ defined". In PCRE2, \K is acted upon when it occurs inside positive
+ assertions, but is ignored in negative assertions. Note that when a
+ pattern such as (?=ab\K) matches, the reported start of the match can
+ be greater than the end of the match.
+
+ Simple assertions
+
+ The final use of backslash is for certain simple assertions. An asser-
+ tion specifies a condition that has to be met at a particular point in
+ a match, without consuming any characters from the subject string. The
+ use of subpatterns for more complicated assertions is described below.
+ The backslashed assertions are:
+
+ \b matches at a word boundary
+ \B matches when not at a word boundary
+ \A matches at the start of the subject
+ \Z matches at the end of the subject
+ also matches before a newline at the end of the subject
+ \z matches only at the end of the subject
+ \G matches at the first matching position in the subject
+
+ Inside a character class, \b has a different meaning; it matches the
+ backspace character. If any other of these assertions appears in a
+ character class, an "invalid escape sequence" error is generated.
+
+ A word boundary is a position in the subject string where the current
+ character and the previous character do not both match \w or \W (i.e.
+ one matches \w and the other matches \W), or the start or end of the
+ string if the first or last character matches \w, respectively. In a
+ UTF mode, the meanings of \w and \W can be changed by setting the
+ PCRE2_UCP option. When this is done, it also affects \b and \B. Neither
+ PCRE2 nor Perl has a separate "start of word" or "end of word" metase-
+ quence. However, whatever follows \b normally determines which it is.
+ For example, the fragment \ba matches "a" at the start of a word.
+
+ The \A, \Z, and \z assertions differ from the traditional circumflex
+ and dollar (described in the next section) in that they only ever match
+ at the very start and end of the subject string, whatever options are
+ set. Thus, they are independent of multiline mode. These three asser-
+ tions are not affected by the PCRE2_NOTBOL or PCRE2_NOTEOL options,
+ which affect only the behaviour of the circumflex and dollar metachar-
+ acters. However, if the startoffset argument of pcre2_match() is non-
+ zero, indicating that matching is to start at a point other than the
+ beginning of the subject, \A can never match. The difference between
+ \Z and \z is that \Z matches before a newline at the end of the string
+ as well as at the very end, whereas \z matches only at the end.
+
+ The \G assertion is true only when the current matching position is at
+ the start point of the match, as specified by the startoffset argument
+ of pcre2_match(). It differs from \A when the value of startoffset is
+ non-zero. By calling pcre2_match() multiple times with appropriate
+ arguments, you can mimic Perl's /g option, and it is in this kind of
+ implementation where \G can be useful.
+
+ Note, however, that PCRE2's interpretation of \G, as the start of the
+ current match, is subtly different from Perl's, which defines it as the
+ end of the previous match. In Perl, these can be different when the
+ previously matched string was empty. Because PCRE2 does just one match
+ at a time, it cannot reproduce this behaviour.
+
+ If all the alternatives of a pattern begin with \G, the expression is
+ anchored to the starting match position, and the "anchored" flag is set
+ in the compiled regular expression.
+
+
+CIRCUMFLEX AND DOLLAR
+
+ The circumflex and dollar metacharacters are zero-width assertions.
+ That is, they test for a particular condition being true without con-
+ suming any characters from the subject string. These two metacharacters
+ are concerned with matching the starts and ends of lines. If the new-
+ line convention is set so that only the two-character sequence CRLF is
+ recognized as a newline, isolated CR and LF characters are treated as
+ ordinary data characters, and are not recognized as newlines.
+
+ Outside a character class, in the default matching mode, the circumflex
+ character is an assertion that is true only if the current matching
+ point is at the start of the subject string. If the startoffset argu-
+ ment of pcre2_match() is non-zero, or if PCRE2_NOTBOL is set, circum-
+ flex can never match if the PCRE2_MULTILINE option is unset. Inside a
+ character class, circumflex has an entirely different meaning (see
+ below).
+
+ Circumflex need not be the first character of the pattern if a number
+ of alternatives are involved, but it should be the first thing in each
+ alternative in which it appears if the pattern is ever to match that
+ branch. If all possible alternatives start with a circumflex, that is,
+ if the pattern is constrained to match only at the start of the sub-
+ ject, it is said to be an "anchored" pattern. (There are also other
+ constructs that can cause a pattern to be anchored.)
+
+ The dollar character is an assertion that is true only if the current
+ matching point is at the end of the subject string, or immediately
+ before a newline at the end of the string (by default), unless
+ PCRE2_NOTEOL is set. Note, however, that it does not actually match the
+ newline. Dollar need not be the last character of the pattern if a num-
+ ber of alternatives are involved, but it should be the last item in any
+ branch in which it appears. Dollar has no special meaning in a charac-
+ ter class.
+
+ The meaning of dollar can be changed so that it matches only at the
+ very end of the string, by setting the PCRE2_DOLLAR_ENDONLY option at
+ compile time. This does not affect the \Z assertion.
+
+ The meanings of the circumflex and dollar metacharacters are changed if
+ the PCRE2_MULTILINE option is set. When this is the case, a dollar
+ character matches before any newlines in the string, as well as at the
+ very end, and a circumflex matches immediately after internal newlines
+ as well as at the start of the subject string. It does not match after
+ a newline that ends the string, for compatibility with Perl. However,
+ this can be changed by setting the PCRE2_ALT_CIRCUMFLEX option.
+
+ For example, the pattern /^abc$/ matches the subject string "def\nabc"
+ (where \n represents a newline) in multiline mode, but not otherwise.
+ Consequently, patterns that are anchored in single line mode because
+ all branches start with ^ are not anchored in multiline mode, and a
+ match for circumflex is possible when the startoffset argument of
+ pcre2_match() is non-zero. The PCRE2_DOLLAR_ENDONLY option is ignored
+ if PCRE2_MULTILINE is set.
+
+ When the newline convention (see "Newline conventions" below) recog-
+ nizes the two-character sequence CRLF as a newline, this is preferred,
+ even if the single characters CR and LF are also recognized as new-
+ lines. For example, if the newline convention is "any", a multiline
+ mode circumflex matches before "xyz" in the string "abc\r\nxyz" rather
+ than after CR, even though CR on its own is a valid newline. (It also
+ matches at the very start of the string, of course.)
+
+ Note that the sequences \A, \Z, and \z can be used to match the start
+ and end of the subject in both modes, and if all branches of a pattern
+ start with \A it is always anchored, whether or not PCRE2_MULTILINE is
+ set.
+
+
+FULL STOP (PERIOD, DOT) AND \N
+
+ Outside a character class, a dot in the pattern matches any one charac-
+ ter in the subject string except (by default) a character that signi-
+ fies the end of a line.
+
+ When a line ending is defined as a single character, dot never matches
+ that character; when the two-character sequence CRLF is used, dot does
+ not match CR if it is immediately followed by LF, but otherwise it
+ matches all characters (including isolated CRs and LFs). When any Uni-
+ code line endings are being recognized, dot does not match CR or LF or
+ any of the other line ending characters.
+
+ The behaviour of dot with regard to newlines can be changed. If the
+ PCRE2_DOTALL option is set, a dot matches any one character, without
+ exception. If the two-character sequence CRLF is present in the sub-
+ ject string, it takes two dots to match it.
+
+ The handling of dot is entirely independent of the handling of circum-
+ flex and dollar, the only relationship being that they both involve
+ newlines. Dot has no special meaning in a character class.
+
+ The escape sequence \N behaves like a dot, except that it is not
+ affected by the PCRE2_DOTALL option. In other words, it matches any
+ character except one that signifies the end of a line. Perl also uses
+ \N to match characters by name; PCRE2 does not support this.
+
+
+MATCHING A SINGLE CODE UNIT
+
+ Outside a character class, the escape sequence \C matches any one code
+ unit, whether or not a UTF mode is set. In the 8-bit library, one code
+ unit is one byte; in the 16-bit library it is a 16-bit unit; in the
+ 32-bit library it is a 32-bit unit. Unlike a dot, \C always matches
+ line-ending characters. The feature is provided in Perl in order to
+ match individual bytes in UTF-8 mode, but it is unclear how it can use-
+ fully be used.
+
+ Because \C breaks up characters into individual code units, matching
+ one unit with \C in UTF-8 or UTF-16 mode means that the rest of the
+ string may start with a malformed UTF character. This has undefined
+ results, because PCRE2 assumes that it is matching character by charac-
+ ter in a valid UTF string (by default it checks the subject string's
+ validity at the start of processing unless the PCRE2_NO_UTF_CHECK
+ option is used).
+
+ An application can lock out the use of \C by setting the
+ PCRE2_NEVER_BACKSLASH_C option when compiling a pattern. It is also
+ possible to build PCRE2 with the use of \C permanently disabled.
+
+ PCRE2 does not allow \C to appear in lookbehind assertions (described
+ below) in a UTF mode, because this would make it impossible to calcu-
+ late the length of the lookbehind. Neither the alternative matching
+ function pcre2_dfa_match() not the JIT optimizer support \C in a UTF
+ mode. The former gives a match-time error; the latter fails to optimize
+ and so the match is always run using the interpreter.
+
+ In general, the \C escape sequence is best avoided. However, one way of
+ using it that avoids the problem of malformed UTF characters is to use
+ a lookahead to check the length of the next character, as in this pat-
+ tern, which could be used with a UTF-8 string (ignore white space and
+ line breaks):
+
+ (?| (?=[\x00-\x7f])(\C) |
+ (?=[\x80-\x{7ff}])(\C)(\C) |
+ (?=[\x{800}-\x{ffff}])(\C)(\C)(\C) |
+ (?=[\x{10000}-\x{1fffff}])(\C)(\C)(\C)(\C))
+
+ In this example, a group that starts with (?| resets the capturing
+ parentheses numbers in each alternative (see "Duplicate Subpattern Num-
+ bers" below). The assertions at the start of each branch check the next
+ UTF-8 character for values whose encoding uses 1, 2, 3, or 4 bytes,
+ respectively. The character's individual bytes are then captured by the
+ appropriate number of \C groups.
+
+
+SQUARE BRACKETS AND CHARACTER CLASSES
+
+ An opening square bracket introduces a character class, terminated by a
+ closing square bracket. A closing square bracket on its own is not spe-
+ cial by default. If a closing square bracket is required as a member
+ of the class, it should be the first data character in the class (after
+ an initial circumflex, if present) or escaped with a backslash. This
+ means that, by default, an empty class cannot be defined. However, if
+ the PCRE2_ALLOW_EMPTY_CLASS option is set, a closing square bracket at
+ the start does end the (empty) class.
+
+ A character class matches a single character in the subject. A matched
+ character must be in the set of characters defined by the class, unless
+ the first character in the class definition is a circumflex, in which
+ case the subject character must not be in the set defined by the class.
+ If a circumflex is actually required as a member of the class, ensure
+ it is not the first character, or escape it with a backslash.
+
+ For example, the character class [aeiou] matches any lower case vowel,
+ while [^aeiou] matches any character that is not a lower case vowel.
+ Note that a circumflex is just a convenient notation for specifying the
+ characters that are in the class by enumerating those that are not. A
+ class that starts with a circumflex is not an assertion; it still con-
+ sumes a character from the subject string, and therefore it fails if
+ the current pointer is at the end of the string.
+
+ When caseless matching is set, any letters in a class represent both
+ their upper case and lower case versions, so for example, a caseless
+ [aeiou] matches "A" as well as "a", and a caseless [^aeiou] does not
+ match "A", whereas a caseful version would.
+
+ Characters that might indicate line breaks are never treated in any
+ special way when matching character classes, whatever line-ending
+ sequence is in use, and whatever setting of the PCRE2_DOTALL and
+ PCRE2_MULTILINE options is used. A class such as [^a] always matches
+ one of these characters.
+
+ The minus (hyphen) character can be used to specify a range of charac-
+ ters in a character class. For example, [d-m] matches any letter
+ between d and m, inclusive. If a minus character is required in a
+ class, it must be escaped with a backslash or appear in a position
+ where it cannot be interpreted as indicating a range, typically as the
+ first or last character in the class, or immediately after a range. For
+ example, [b-d-z] matches letters in the range b to d, a hyphen charac-
+ ter, or z.
+
+ It is not possible to have the literal character "]" as the end charac-
+ ter of a range. A pattern such as [W-]46] is interpreted as a class of
+ two characters ("W" and "-") followed by a literal string "46]", so it
+ would match "W46]" or "-46]". However, if the "]" is escaped with a
+ backslash it is interpreted as the end of range, so [W-\]46] is inter-
+ preted as a class containing a range followed by two other characters.
+ The octal or hexadecimal representation of "]" can also be used to end
+ a range.
+
+ An error is generated if a POSIX character class (see below) or an
+ escape sequence other than one that defines a single character appears
+ at a point where a range ending character is expected. For example,
+ [z-\xff] is valid, but [A-\d] and [A-[:digit:]] are not.
+
+ Ranges normally include all code points between the start and end char-
+ acters, inclusive. They can also be used for code points specified
+ numerically, for example [\000-\037]. Ranges can include any characters
+ that are valid for the current mode.
+
+ There is a special case in EBCDIC environments for ranges whose end
+ points are both specified as literal letters in the same case. For com-
+ patibility with Perl, EBCDIC code points within the range that are not
+ letters are omitted. For example, [h-k] matches only four characters,
+ even though the codes for h and k are 0x88 and 0x92, a range of 11 code
+ points. However, if the range is specified numerically, for example,
+ [\x88-\x92] or [h-\x92], all code points are included.
+
+ If a range that includes letters is used when caseless matching is set,
+ it matches the letters in either case. For example, [W-c] is equivalent
+ to [][\\^_`wxyzabc], matched caselessly, and in a non-UTF mode, if
+ character tables for a French locale are in use, [\xc8-\xcb] matches
+ accented E characters in both cases.
+
+ The character escape sequences \d, \D, \h, \H, \p, \P, \s, \S, \v, \V,
+ \w, and \W may appear in a character class, and add the characters that
+ they match to the class. For example, [\dABCDEF] matches any hexadeci-
+ mal digit. In UTF modes, the PCRE2_UCP option affects the meanings of
+ \d, \s, \w and their upper case partners, just as it does when they
+ appear outside a character class, as described in the section entitled
+ "Generic character types" above. The escape sequence \b has a different
+ meaning inside a character class; it matches the backspace character.
+ The sequences \B, \N, \R, and \X are not special inside a character
+ class. Like any other unrecognized escape sequences, they cause an
+ error.
+
+ A circumflex can conveniently be used with the upper case character
+ types to specify a more restricted set of characters than the matching
+ lower case type. For example, the class [^\W_] matches any letter or
+ digit, but not underscore, whereas [\w] includes underscore. A positive
+ character class should be read as "something OR something OR ..." and a
+ negative class as "NOT something AND NOT something AND NOT ...".
+
+ The only metacharacters that are recognized in character classes are
+ backslash, hyphen (only where it can be interpreted as specifying a
+ range), circumflex (only at the start), opening square bracket (only
+ when it can be interpreted as introducing a POSIX class name, or for a
+ special compatibility feature - see the next two sections), and the
+ terminating closing square bracket. However, escaping other non-
+ alphanumeric characters does no harm.
+
+
+POSIX CHARACTER CLASSES
+
+ Perl supports the POSIX notation for character classes. This uses names
+ enclosed by [: and :] within the enclosing square brackets. PCRE2 also
+ supports this notation. For example,
+
+ [01[:alpha:]%]
+
+ matches "0", "1", any alphabetic character, or "%". The supported class
+ names are:
+
+ alnum letters and digits
+ alpha letters
+ ascii character codes 0 - 127
+ blank space or tab only
+ cntrl control characters
+ digit decimal digits (same as \d)
+ graph printing characters, excluding space
+ lower lower case letters
+ print printing characters, including space
+ punct printing characters, excluding letters and digits and space
+ space white space (the same as \s from PCRE2 8.34)
+ upper upper case letters
+ word "word" characters (same as \w)
+ xdigit hexadecimal digits
+
+ The default "space" characters are HT (9), LF (10), VT (11), FF (12),
+ CR (13), and space (32). If locale-specific matching is taking place,
+ the list of space characters may be different; there may be fewer or
+ more of them. "Space" and \s match the same set of characters.
+
+ The name "word" is a Perl extension, and "blank" is a GNU extension
+ from Perl 5.8. Another Perl extension is negation, which is indicated
+ by a ^ character after the colon. For example,
+
+ [12[:^digit:]]
+
+ matches "1", "2", or any non-digit. PCRE2 (and Perl) also recognize the
+ POSIX syntax [.ch.] and [=ch=] where "ch" is a "collating element", but
+ these are not supported, and an error is given if they are encountered.
+
+ By default, characters with values greater than 127 do not match any of
+ the POSIX character classes, although this may be different for charac-
+ ters in the range 128-255 when locale-specific matching is happening.
+ However, if the PCRE2_UCP option is passed to pcre2_compile(), some of
+ the classes are changed so that Unicode character properties are used.
+ This is achieved by replacing certain POSIX classes with other
+ sequences, as follows:
+
+ [:alnum:] becomes \p{Xan}
+ [:alpha:] becomes \p{L}
+ [:blank:] becomes \h
+ [:cntrl:] becomes \p{Cc}
+ [:digit:] becomes \p{Nd}
+ [:lower:] becomes \p{Ll}
+ [:space:] becomes \p{Xps}
+ [:upper:] becomes \p{Lu}
+ [:word:] becomes \p{Xwd}
+
+ Negated versions, such as [:^alpha:] use \P instead of \p. Three other
+ POSIX classes are handled specially in UCP mode:
+
+ [:graph:] This matches characters that have glyphs that mark the page
+ when printed. In Unicode property terms, it matches all char-
+ acters with the L, M, N, P, S, or Cf properties, except for:
+
+ U+061C Arabic Letter Mark
+ U+180E Mongolian Vowel Separator
+ U+2066 - U+2069 Various "isolate"s
+
+
+ [:print:] This matches the same characters as [:graph:] plus space
+ characters that are not controls, that is, characters with
+ the Zs property.
+
+ [:punct:] This matches all characters that have the Unicode P (punctua-
+ tion) property, plus those characters with code points less
+ than 256 that have the S (Symbol) property.
+
+ The other POSIX classes are unchanged, and match only characters with
+ code points less than 256.
+
+
+COMPATIBILITY FEATURE FOR WORD BOUNDARIES
+
+ In the POSIX.2 compliant library that was included in 4.4BSD Unix, the
+ ugly syntax [[:<:]] and [[:>:]] is used for matching "start of word"
+ and "end of word". PCRE2 treats these items as follows:
+
+ [[:<:]] is converted to \b(?=\w)
+ [[:>:]] is converted to \b(?<=\w)
+
+ Only these exact character sequences are recognized. A sequence such as
+ [a[:<:]b] provokes error for an unrecognized POSIX class name. This
+ support is not compatible with Perl. It is provided to help migrations
+ from other environments, and is best not used in any new patterns. Note
+ that \b matches at the start and the end of a word (see "Simple asser-
+ tions" above), and in a Perl-style pattern the preceding or following
+ character normally shows which is wanted, without the need for the
+ assertions that are used above in order to give exactly the POSIX be-
+ haviour.
+
+
+VERTICAL BAR
+
+ Vertical bar characters are used to separate alternative patterns. For
+ example, the pattern
+
+ gilbert|sullivan
+
+ matches either "gilbert" or "sullivan". Any number of alternatives may
+ appear, and an empty alternative is permitted (matching the empty
+ string). The matching process tries each alternative in turn, from left
+ to right, and the first one that succeeds is used. If the alternatives
+ are within a subpattern (defined below), "succeeds" means matching the
+ rest of the main pattern as well as the alternative in the subpattern.
+
+
+INTERNAL OPTION SETTING
+
+ The settings of the PCRE2_CASELESS, PCRE2_MULTILINE, PCRE2_DOTALL, and
+ PCRE2_EXTENDED options (which are Perl-compatible) can be changed from
+ within the pattern by a sequence of Perl option letters enclosed
+ between "(?" and ")". The option letters are
+
+ i for PCRE2_CASELESS
+ m for PCRE2_MULTILINE
+ s for PCRE2_DOTALL
+ x for PCRE2_EXTENDED
+
+ For example, (?im) sets caseless, multiline matching. It is also possi-
+ ble to unset these options by preceding the letter with a hyphen, and a
+ combined setting and unsetting such as (?im-sx), which sets PCRE2_CASE-
+ LESS and PCRE2_MULTILINE while unsetting PCRE2_DOTALL and
+ PCRE2_EXTENDED, is also permitted. If a letter appears both before and
+ after the hyphen, the option is unset. An empty options setting "(?)"
+ is allowed. Needless to say, it has no effect.
+
+ The PCRE2-specific options PCRE2_DUPNAMES and PCRE2_UNGREEDY can be
+ changed in the same way as the Perl-compatible options by using the
+ characters J and U respectively.
+
+ When one of these option changes occurs at top level (that is, not
+ inside subpattern parentheses), the change applies to the remainder of
+ the pattern that follows. If the change is placed right at the start of
+ a pattern, PCRE2 extracts it into the global options (and it will
+ therefore show up in data extracted by the pcre2_pattern_info() func-
+ tion).
+
+ An option change within a subpattern (see below for a description of
+ subpatterns) affects only that part of the subpattern that follows it,
+ so
+
+ (a(?i)b)c
+
+ matches abc and aBc and no other strings (assuming PCRE2_CASELESS is
+ not used). By this means, options can be made to have different set-
+ tings in different parts of the pattern. Any changes made in one alter-
+ native do carry on into subsequent branches within the same subpattern.
+ For example,
+
+ (a(?i)b|c)
+
+ matches "ab", "aB", "c", and "C", even though when matching "C" the
+ first branch is abandoned before the option setting. This is because
+ the effects of option settings happen at compile time. There would be
+ some very weird behaviour otherwise.
+
+ As a convenient shorthand, if any option settings are required at the
+ start of a non-capturing subpattern (see the next section), the option
+ letters may appear between the "?" and the ":". Thus the two patterns
+
+ (?i:saturday|sunday)
+ (?:(?i)saturday|sunday)
+
+ match exactly the same set of strings.
+
+ Note: There are other PCRE2-specific options that can be set by the
+ application when the compiling function is called. The pattern can con-
+ tain special leading sequences such as (*CRLF) to override what the
+ application has set or what has been defaulted. Details are given in
+ the section entitled "Newline sequences" above. There are also the
+ (*UTF) and (*UCP) leading sequences that can be used to set UTF and
+ Unicode property modes; they are equivalent to setting the PCRE2_UTF
+ and PCRE2_UCP options, respectively. However, the application can set
+ the PCRE2_NEVER_UTF and PCRE2_NEVER_UCP options, which lock out the use
+ of the (*UTF) and (*UCP) sequences.
+
+
+SUBPATTERNS
+
+ Subpatterns are delimited by parentheses (round brackets), which can be
+ nested. Turning part of a pattern into a subpattern does two things:
+
+ 1. It localizes a set of alternatives. For example, the pattern
+
+ cat(aract|erpillar|)
+
+ matches "cataract", "caterpillar", or "cat". Without the parentheses,
+ it would match "cataract", "erpillar" or an empty string.
+
+ 2. It sets up the subpattern as a capturing subpattern. This means
+ that, when the whole pattern matches, the portion of the subject string
+ that matched the subpattern is passed back to the caller, separately
+ from the portion that matched the whole pattern. (This applies only to
+ the traditional matching function; the DFA matching function does not
+ support capturing.)
+
+ Opening parentheses are counted from left to right (starting from 1) to
+ obtain numbers for the capturing subpatterns. For example, if the
+ string "the red king" is matched against the pattern
+
+ the ((red|white) (king|queen))
+
+ the captured substrings are "red king", "red", and "king", and are num-
+ bered 1, 2, and 3, respectively.
+
+ The fact that plain parentheses fulfil two functions is not always
+ helpful. There are often times when a grouping subpattern is required
+ without a capturing requirement. If an opening parenthesis is followed
+ by a question mark and a colon, the subpattern does not do any captur-
+ ing, and is not counted when computing the number of any subsequent
+ capturing subpatterns. For example, if the string "the white queen" is
+ matched against the pattern
+
+ the ((?:red|white) (king|queen))
+
+ the captured substrings are "white queen" and "queen", and are numbered
+ 1 and 2. The maximum number of capturing subpatterns is 65535.
+
+ As a convenient shorthand, if any option settings are required at the
+ start of a non-capturing subpattern, the option letters may appear
+ between the "?" and the ":". Thus the two patterns
+
+ (?i:saturday|sunday)
+ (?:(?i)saturday|sunday)
+
+ match exactly the same set of strings. Because alternative branches are
+ tried from left to right, and options are not reset until the end of
+ the subpattern is reached, an option setting in one branch does affect
+ subsequent branches, so the above patterns match "SUNDAY" as well as
+ "Saturday".
+
+
+DUPLICATE SUBPATTERN NUMBERS
+
+ Perl 5.10 introduced a feature whereby each alternative in a subpattern
+ uses the same numbers for its capturing parentheses. Such a subpattern
+ starts with (?| and is itself a non-capturing subpattern. For example,
+ consider this pattern:
+
+ (?|(Sat)ur|(Sun))day
+
+ Because the two alternatives are inside a (?| group, both sets of cap-
+ turing parentheses are numbered one. Thus, when the pattern matches,
+ you can look at captured substring number one, whichever alternative
+ matched. This construct is useful when you want to capture part, but
+ not all, of one of a number of alternatives. Inside a (?| group, paren-
+ theses are numbered as usual, but the number is reset at the start of
+ each branch. The numbers of any capturing parentheses that follow the
+ subpattern start after the highest number used in any branch. The fol-
+ lowing example is taken from the Perl documentation. The numbers under-
+ neath show in which buffer the captured content will be stored.
+
+ # before ---------------branch-reset----------- after
+ / ( a ) (?| x ( y ) z | (p (q) r) | (t) u (v) ) ( z ) /x
+ # 1 2 2 3 2 3 4
+
+ A back reference to a numbered subpattern uses the most recent value
+ that is set for that number by any subpattern. The following pattern
+ matches "abcabc" or "defdef":
+
+ /(?|(abc)|(def))\1/
+
+ In contrast, a subroutine call to a numbered subpattern always refers
+ to the first one in the pattern with the given number. The following
+ pattern matches "abcabc" or "defabc":
+
+ /(?|(abc)|(def))(?1)/
+
+ A relative reference such as (?-1) is no different: it is just a conve-
+ nient way of computing an absolute group number.
+
+ If a condition test for a subpattern's having matched refers to a non-
+ unique number, the test is true if any of the subpatterns of that num-
+ ber have matched.
+
+ An alternative approach to using this "branch reset" feature is to use
+ duplicate named subpatterns, as described in the next section.
+
+
+NAMED SUBPATTERNS
+
+ Identifying capturing parentheses by number is simple, but it can be
+ very hard to keep track of the numbers in complicated regular expres-
+ sions. Furthermore, if an expression is modified, the numbers may
+ change. To help with this difficulty, PCRE2 supports the naming of sub-
+ patterns. This feature was not added to Perl until release 5.10. Python
+ had the feature earlier, and PCRE1 introduced it at release 4.0, using
+ the Python syntax. PCRE2 supports both the Perl and the Python syntax.
+ Perl allows identically numbered subpatterns to have different names,
+ but PCRE2 does not.
+
+ In PCRE2, a subpattern can be named in one of three ways: (?<name>...)
+ or (?'name'...) as in Perl, or (?P<name>...) as in Python. References
+ to capturing parentheses from other parts of the pattern, such as back
+ references, recursion, and conditions, can be made by name as well as
+ by number.
+
+ Names consist of up to 32 alphanumeric characters and underscores, but
+ must start with a non-digit. Named capturing parentheses are still
+ allocated numbers as well as names, exactly as if the names were not
+ present. The PCRE2 API provides function calls for extracting the name-
+ to-number translation table from a compiled pattern. There are also
+ convenience functions for extracting a captured substring by name.
+
+ By default, a name must be unique within a pattern, but it is possible
+ to relax this constraint by setting the PCRE2_DUPNAMES option at com-
+ pile time. (Duplicate names are also always permitted for subpatterns
+ with the same number, set up as described in the previous section.)
+ Duplicate names can be useful for patterns where only one instance of
+ the named parentheses can match. Suppose you want to match the name of
+ a weekday, either as a 3-letter abbreviation or as the full name, and
+ in both cases you want to extract the abbreviation. This pattern
+ (ignoring the line breaks) does the job:
+
+ (?<DN>Mon|Fri|Sun)(?:day)?|
+ (?<DN>Tue)(?:sday)?|
+ (?<DN>Wed)(?:nesday)?|
+ (?<DN>Thu)(?:rsday)?|
+ (?<DN>Sat)(?:urday)?
+
+ There are five capturing substrings, but only one is ever set after a
+ match. (An alternative way of solving this problem is to use a "branch
+ reset" subpattern, as described in the previous section.)
+
+ The convenience functions for extracting the data by name returns the
+ substring for the first (and in this example, the only) subpattern of
+ that name that matched. This saves searching to find which numbered
+ subpattern it was.
+
+ If you make a back reference to a non-unique named subpattern from
+ elsewhere in the pattern, the subpatterns to which the name refers are
+ checked in the order in which they appear in the overall pattern. The
+ first one that is set is used for the reference. For example, this pat-
+ tern matches both "foofoo" and "barbar" but not "foobar" or "barfoo":
+
+ (?:(?<n>foo)|(?<n>bar))\k<n>
+
+
+ If you make a subroutine call to a non-unique named subpattern, the one
+ that corresponds to the first occurrence of the name is used. In the
+ absence of duplicate numbers (see the previous section) this is the one
+ with the lowest number.
+
+ If you use a named reference in a condition test (see the section about
+ conditions below), either to check whether a subpattern has matched, or
+ to check for recursion, all subpatterns with the same name are tested.
+ If the condition is true for any one of them, the overall condition is
+ true. This is the same behaviour as testing by number. For further
+ details of the interfaces for handling named subpatterns, see the
+ pcre2api documentation.
+
+ Warning: You cannot use different names to distinguish between two sub-
+ patterns with the same number because PCRE2 uses only the numbers when
+ matching. For this reason, an error is given at compile time if differ-
+ ent names are given to subpatterns with the same number. However, you
+ can always give the same name to subpatterns with the same number, even
+ when PCRE2_DUPNAMES is not set.
+
+
+REPETITION
+
+ Repetition is specified by quantifiers, which can follow any of the
+ following items:
+
+ a literal data character
+ the dot metacharacter
+ the \C escape sequence
+ the \X escape sequence
+ the \R escape sequence
+ an escape such as \d or \pL that matches a single character
+ a character class
+ a back reference
+ a parenthesized subpattern (including most assertions)
+ a subroutine call to a subpattern (recursive or otherwise)
+
+ The general repetition quantifier specifies a minimum and maximum num-
+ ber of permitted matches, by giving the two numbers in curly brackets
+ (braces), separated by a comma. The numbers must be less than 65536,
+ and the first must be less than or equal to the second. For example:
+
+ z{2,4}
+
+ matches "zz", "zzz", or "zzzz". A closing brace on its own is not a
+ special character. If the second number is omitted, but the comma is
+ present, there is no upper limit; if the second number and the comma
+ are both omitted, the quantifier specifies an exact number of required
+ matches. Thus
+
+ [aeiou]{3,}
+
+ matches at least 3 successive vowels, but may match many more, whereas
+
+ \d{8}
+
+ matches exactly 8 digits. An opening curly bracket that appears in a
+ position where a quantifier is not allowed, or one that does not match
+ the syntax of a quantifier, is taken as a literal character. For exam-
+ ple, {,6} is not a quantifier, but a literal string of four characters.
+
+ In UTF modes, quantifiers apply to characters rather than to individual
+ code units. Thus, for example, \x{100}{2} matches two characters, each
+ of which is represented by a two-byte sequence in a UTF-8 string. Simi-
+ larly, \X{3} matches three Unicode extended grapheme clusters, each of
+ which may be several code units long (and they may be of different
+ lengths).
+
+ The quantifier {0} is permitted, causing the expression to behave as if
+ the previous item and the quantifier were not present. This may be use-
+ ful for subpatterns that are referenced as subroutines from elsewhere
+ in the pattern (but see also the section entitled "Defining subpatterns
+ for use by reference only" below). Items other than subpatterns that
+ have a {0} quantifier are omitted from the compiled pattern.
+
+ For convenience, the three most common quantifiers have single-charac-
+ ter abbreviations:
+
+ * is equivalent to {0,}
+ + is equivalent to {1,}
+ ? is equivalent to {0,1}
+
+ It is possible to construct infinite loops by following a subpattern
+ that can match no characters with a quantifier that has no upper limit,
+ for example:
+
+ (a?)*
+
+ Earlier versions of Perl and PCRE1 used to give an error at compile
+ time for such patterns. However, because there are cases where this can
+ be useful, such patterns are now accepted, but if any repetition of the
+ subpattern does in fact match no characters, the loop is forcibly bro-
+ ken.
+
+ By default, the quantifiers are "greedy", that is, they match as much
+ as possible (up to the maximum number of permitted times), without
+ causing the rest of the pattern to fail. The classic example of where
+ this gives problems is in trying to match comments in C programs. These
+ appear between /* and */ and within the comment, individual * and /
+ characters may appear. An attempt to match C comments by applying the
+ pattern
+
+ /\*.*\*/
+
+ to the string
+
+ /* first comment */ not comment /* second comment */
+
+ fails, because it matches the entire string owing to the greediness of
+ the .* item.
+
+ If a quantifier is followed by a question mark, it ceases to be greedy,
+ and instead matches the minimum number of times possible, so the pat-
+ tern
+
+ /\*.*?\*/
+
+ does the right thing with the C comments. The meaning of the various
+ quantifiers is not otherwise changed, just the preferred number of
+ matches. Do not confuse this use of question mark with its use as a
+ quantifier in its own right. Because it has two uses, it can sometimes
+ appear doubled, as in
+
+ \d??\d
+
+ which matches one digit by preference, but can match two if that is the
+ only way the rest of the pattern matches.
+
+ If the PCRE2_UNGREEDY option is set (an option that is not available in
+ Perl), the quantifiers are not greedy by default, but individual ones
+ can be made greedy by following them with a question mark. In other
+ words, it inverts the default behaviour.
+
+ When a parenthesized subpattern is quantified with a minimum repeat
+ count that is greater than 1 or with a limited maximum, more memory is
+ required for the compiled pattern, in proportion to the size of the
+ minimum or maximum.
+
+ If a pattern starts with .* or .{0,} and the PCRE2_DOTALL option
+ (equivalent to Perl's /s) is set, thus allowing the dot to match new-
+ lines, the pattern is implicitly anchored, because whatever follows
+ will be tried against every character position in the subject string,
+ so there is no point in retrying the overall match at any position
+ after the first. PCRE2 normally treats such a pattern as though it were
+ preceded by \A.
+
+ In cases where it is known that the subject string contains no new-
+ lines, it is worth setting PCRE2_DOTALL in order to obtain this opti-
+ mization, or alternatively, using ^ to indicate anchoring explicitly.
+
+ However, there are some cases where the optimization cannot be used.
+ When .* is inside capturing parentheses that are the subject of a back
+ reference elsewhere in the pattern, a match at the start may fail where
+ a later one succeeds. Consider, for example:
+
+ (.*)abc\1
+
+ If the subject is "xyz123abc123" the match point is the fourth charac-
+ ter. For this reason, such a pattern is not implicitly anchored.
+
+ Another case where implicit anchoring is not applied is when the lead-
+ ing .* is inside an atomic group. Once again, a match at the start may
+ fail where a later one succeeds. Consider this pattern:
+
+ (?>.*?a)b
+
+ It matches "ab" in the subject "aab". The use of the backtracking con-
+ trol verbs (*PRUNE) and (*SKIP) also disable this optimization, and
+ there is an option, PCRE2_NO_DOTSTAR_ANCHOR, to do so explicitly.
+
+ When a capturing subpattern is repeated, the value captured is the sub-
+ string that matched the final iteration. For example, after
+
+ (tweedle[dume]{3}\s*)+
+
+ has matched "tweedledum tweedledee" the value of the captured substring
+ is "tweedledee". However, if there are nested capturing subpatterns,
+ the corresponding captured values may have been set in previous itera-
+ tions. For example, after
+
+ (a|(b))+
+
+ matches "aba" the value of the second captured substring is "b".
+
+
+ATOMIC GROUPING AND POSSESSIVE QUANTIFIERS
+
+ With both maximizing ("greedy") and minimizing ("ungreedy" or "lazy")
+ repetition, failure of what follows normally causes the repeated item
+ to be re-evaluated to see if a different number of repeats allows the
+ rest of the pattern to match. Sometimes it is useful to prevent this,
+ either to change the nature of the match, or to cause it fail earlier
+ than it otherwise might, when the author of the pattern knows there is
+ no point in carrying on.
+
+ Consider, for example, the pattern \d+foo when applied to the subject
+ line
+
+ 123456bar
+
+ After matching all 6 digits and then failing to match "foo", the normal
+ action of the matcher is to try again with only 5 digits matching the
+ \d+ item, and then with 4, and so on, before ultimately failing.
+ "Atomic grouping" (a term taken from Jeffrey Friedl's book) provides
+ the means for specifying that once a subpattern has matched, it is not
+ to be re-evaluated in this way.
+
+ If we use atomic grouping for the previous example, the matcher gives
+ up immediately on failing to match "foo" the first time. The notation
+ is a kind of special parenthesis, starting with (?> as in this example:
+
+ (?>\d+)foo
+
+ This kind of parenthesis "locks up" the part of the pattern it con-
+ tains once it has matched, and a failure further into the pattern is
+ prevented from backtracking into it. Backtracking past it to previous
+ items, however, works as normal.
+
+ An alternative description is that a subpattern of this type matches
+ exactly the string of characters that an identical standalone pattern
+ would match, if anchored at the current point in the subject string.
+
+ Atomic grouping subpatterns are not capturing subpatterns. Simple cases
+ such as the above example can be thought of as a maximizing repeat that
+ must swallow everything it can. So, while both \d+ and \d+? are pre-
+ pared to adjust the number of digits they match in order to make the
+ rest of the pattern match, (?>\d+) can only match an entire sequence of
+ digits.
+
+ Atomic groups in general can of course contain arbitrarily complicated
+ subpatterns, and can be nested. However, when the subpattern for an
+ atomic group is just a single repeated item, as in the example above, a
+ simpler notation, called a "possessive quantifier" can be used. This
+ consists of an additional + character following a quantifier. Using
+ this notation, the previous example can be rewritten as
+
+ \d++foo
+
+ Note that a possessive quantifier can be used with an entire group, for
+ example:
+
+ (abc|xyz){2,3}+
+
+ Possessive quantifiers are always greedy; the setting of the
+ PCRE2_UNGREEDY option is ignored. They are a convenient notation for
+ the simpler forms of atomic group. However, there is no difference in
+ the meaning of a possessive quantifier and the equivalent atomic group,
+ though there may be a performance difference; possessive quantifiers
+ should be slightly faster.
+
+ The possessive quantifier syntax is an extension to the Perl 5.8 syn-
+ tax. Jeffrey Friedl originated the idea (and the name) in the first
+ edition of his book. Mike McCloskey liked it, so implemented it when he
+ built Sun's Java package, and PCRE1 copied it from there. It ultimately
+ found its way into Perl at release 5.10.
+
+ PCRE2 has an optimization that automatically "possessifies" certain
+ simple pattern constructs. For example, the sequence A+B is treated as
+ A++B because there is no point in backtracking into a sequence of A's
+ when B must follow. This feature can be disabled by the PCRE2_NO_AUTO-
+ POSSESS option, or starting the pattern with (*NO_AUTO_POSSESS).
+
+ When a pattern contains an unlimited repeat inside a subpattern that
+ can itself be repeated an unlimited number of times, the use of an
+ atomic group is the only way to avoid some failing matches taking a
+ very long time indeed. The pattern
+
+ (\D+|<\d+>)*[!?]
+
+ matches an unlimited number of substrings that either consist of non-
+ digits, or digits enclosed in <>, followed by either ! or ?. When it
+ matches, it runs quickly. However, if it is applied to
+
+ aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
+
+ it takes a long time before reporting failure. This is because the
+ string can be divided between the internal \D+ repeat and the external
+ * repeat in a large number of ways, and all have to be tried. (The
+ example uses [!?] rather than a single character at the end, because
+ both PCRE2 and Perl have an optimization that allows for fast failure
+ when a single character is used. They remember the last single charac-
+ ter that is required for a match, and fail early if it is not present
+ in the string.) If the pattern is changed so that it uses an atomic
+ group, like this:
+
+ ((?>\D+)|<\d+>)*[!?]
+
+ sequences of non-digits cannot be broken, and failure happens quickly.
+
+
+BACK REFERENCES
+
+ Outside a character class, a backslash followed by a digit greater than
+ 0 (and possibly further digits) is a back reference to a capturing sub-
+ pattern earlier (that is, to its left) in the pattern, provided there
+ have been that many previous capturing left parentheses.
+
+ However, if the decimal number following the backslash is less than 8,
+ it is always taken as a back reference, and causes an error only if
+ there are not that many capturing left parentheses in the entire pat-
+ tern. In other words, the parentheses that are referenced need not be
+ to the left of the reference for numbers less than 8. A "forward back
+ reference" of this type can make sense when a repetition is involved
+ and the subpattern to the right has participated in an earlier itera-
+ tion.
+
+ It is not possible to have a numerical "forward back reference" to a
+ subpattern whose number is 8 or more using this syntax because a
+ sequence such as \50 is interpreted as a character defined in octal.
+ See the subsection entitled "Non-printing characters" above for further
+ details of the handling of digits following a backslash. There is no
+ such problem when named parentheses are used. A back reference to any
+ subpattern is possible using named parentheses (see below).
+
+ Another way of avoiding the ambiguity inherent in the use of digits
+ following a backslash is to use the \g escape sequence. This escape
+ must be followed by an unsigned number or a negative number, optionally
+ enclosed in braces. These examples are all identical:
+
+ (ring), \1
+ (ring), \g1
+ (ring), \g{1}
+
+ An unsigned number specifies an absolute reference without the ambigu-
+ ity that is present in the older syntax. It is also useful when literal
+ digits follow the reference. A negative number is a relative reference.
+ Consider this example:
+
+ (abc(def)ghi)\g{-1}
+
+ The sequence \g{-1} is a reference to the most recently started captur-
+ ing subpattern before \g, that is, is it equivalent to \2 in this exam-
+ ple. Similarly, \g{-2} would be equivalent to \1. The use of relative
+ references can be helpful in long patterns, and also in patterns that
+ are created by joining together fragments that contain references
+ within themselves.
+
+ A back reference matches whatever actually matched the capturing sub-
+ pattern in the current subject string, rather than anything matching
+ the subpattern itself (see "Subpatterns as subroutines" below for a way
+ of doing that). So the pattern
+
+ (sens|respons)e and \1ibility
+
+ matches "sense and sensibility" and "response and responsibility", but
+ not "sense and responsibility". If caseful matching is in force at the
+ time of the back reference, the case of letters is relevant. For exam-
+ ple,
+
+ ((?i)rah)\s+\1
+
+ matches "rah rah" and "RAH RAH", but not "RAH rah", even though the
+ original capturing subpattern is matched caselessly.
+
+ There are several different ways of writing back references to named
+ subpatterns. The .NET syntax \k{name} and the Perl syntax \k<name> or
+ \k'name' are supported, as is the Python syntax (?P=name). Perl 5.10's
+ unified back reference syntax, in which \g can be used for both numeric
+ and named references, is also supported. We could rewrite the above
+ example in any of the following ways:
+
+ (?<p1>(?i)rah)\s+\k<p1>
+ (?'p1'(?i)rah)\s+\k{p1}
+ (?P<p1>(?i)rah)\s+(?P=p1)
+ (?<p1>(?i)rah)\s+\g{p1}
+
+ A subpattern that is referenced by name may appear in the pattern
+ before or after the reference.
+
+ There may be more than one back reference to the same subpattern. If a
+ subpattern has not actually been used in a particular match, any back
+ references to it always fail by default. For example, the pattern
+
+ (a|(bc))\2
+
+ always fails if it starts to match "a" rather than "bc". However, if
+ the PCRE2_MATCH_UNSET_BACKREF option is set at compile time, a back
+ reference to an unset value matches an empty string.
+
+ Because there may be many capturing parentheses in a pattern, all dig-
+ its following a backslash are taken as part of a potential back refer-
+ ence number. If the pattern continues with a digit character, some
+ delimiter must be used to terminate the back reference. If the
+ PCRE2_EXTENDED option is set, this can be white space. Otherwise, the
+ \g{ syntax or an empty comment (see "Comments" below) can be used.
+
+ Recursive back references
+
+ A back reference that occurs inside the parentheses to which it refers
+ fails when the subpattern is first used, so, for example, (a\1) never
+ matches. However, such references can be useful inside repeated sub-
+ patterns. For example, the pattern
+
+ (a|b\1)+
+
+ matches any number of "a"s and also "aba", "ababbaa" etc. At each iter-
+ ation of the subpattern, the back reference matches the character
+ string corresponding to the previous iteration. In order for this to
+ work, the pattern must be such that the first iteration does not need
+ to match the back reference. This can be done using alternation, as in
+ the example above, or by a quantifier with a minimum of zero.
+
+ Back references of this type cause the group that they reference to be
+ treated as an atomic group. Once the whole group has been matched, a
+ subsequent matching failure cannot cause backtracking into the middle
+ of the group.
+
+
+ASSERTIONS
+
+ An assertion is a test on the characters following or preceding the
+ current matching point that does not consume any characters. The simple
+ assertions coded as \b, \B, \A, \G, \Z, \z, ^ and $ are described
+ above.
+
+ More complicated assertions are coded as subpatterns. There are two
+ kinds: those that look ahead of the current position in the subject
+ string, and those that look behind it. An assertion subpattern is
+ matched in the normal way, except that it does not cause the current
+ matching position to be changed.
+
+ Assertion subpatterns are not capturing subpatterns. If such an asser-
+ tion contains capturing subpatterns within it, these are counted for
+ the purposes of numbering the capturing subpatterns in the whole pat-
+ tern. However, substring capturing is carried out only for positive
+ assertions. (Perl sometimes, but not always, does do capturing in nega-
+ tive assertions.)
+
+ For compatibility with Perl, most assertion subpatterns may be
+ repeated; though it makes no sense to assert the same thing several
+ times, the side effect of capturing parentheses may occasionally be
+ useful. However, an assertion that forms the condition for a condi-
+ tional subpattern may not be quantified. In practice, for other asser-
+ tions, there only three cases:
+
+ (1) If the quantifier is {0}, the assertion is never obeyed during
+ matching. However, it may contain internal capturing parenthesized
+ groups that are called from elsewhere via the subroutine mechanism.
+
+ (2) If quantifier is {0,n} where n is greater than zero, it is treated
+ as if it were {0,1}. At run time, the rest of the pattern match is
+ tried with and without the assertion, the order depending on the greed-
+ iness of the quantifier.
+
+ (3) If the minimum repetition is greater than zero, the quantifier is
+ ignored. The assertion is obeyed just once when encountered during
+ matching.
+
+ Lookahead assertions
+
+ Lookahead assertions start with (?= for positive assertions and (?! for
+ negative assertions. For example,
+
+ \w+(?=;)
+
+ matches a word followed by a semicolon, but does not include the semi-
+ colon in the match, and
+
+ foo(?!bar)
+
+ matches any occurrence of "foo" that is not followed by "bar". Note
+ that the apparently similar pattern
+
+ (?!foo)bar
+
+ does not find an occurrence of "bar" that is preceded by something
+ other than "foo"; it finds any occurrence of "bar" whatsoever, because
+ the assertion (?!foo) is always true when the next three characters are
+ "bar". A lookbehind assertion is needed to achieve the other effect.
+
+ If you want to force a matching failure at some point in a pattern, the
+ most convenient way to do it is with (?!) because an empty string
+ always matches, so an assertion that requires there not to be an empty
+ string must always fail. The backtracking control verb (*FAIL) or (*F)
+ is a synonym for (?!).
+
+ Lookbehind assertions
+
+ Lookbehind assertions start with (?<= for positive assertions and (?<!
+ for negative assertions. For example,
+
+ (?<!foo)bar
+
+ does find an occurrence of "bar" that is not preceded by "foo". The
+ contents of a lookbehind assertion are restricted such that all the
+ strings it matches must have a fixed length. However, if there are sev-
+ eral top-level alternatives, they do not all have to have the same
+ fixed length. Thus
+
+ (?<=bullock|donkey)
+
+ is permitted, but
+
+ (?<!dogs?|cats?)
+
+ causes an error at compile time. Branches that match different length
+ strings are permitted only at the top level of a lookbehind assertion.
+ This is an extension compared with Perl, which requires all branches to
+ match the same length of string. An assertion such as
+
+ (?<=ab(c|de))
+
+ is not permitted, because its single top-level branch can match two
+ different lengths, but it is acceptable to PCRE2 if rewritten to use
+ two top-level branches:
+
+ (?<=abc|abde)
+
+ In some cases, the escape sequence \K (see above) can be used instead
+ of a lookbehind assertion to get round the fixed-length restriction.
+
+ The implementation of lookbehind assertions is, for each alternative,
+ to temporarily move the current position back by the fixed length and
+ then try to match. If there are insufficient characters before the cur-
+ rent position, the assertion fails.
+
+ In a UTF mode, PCRE2 does not allow the \C escape (which matches a sin-
+ gle code unit even in a UTF mode) to appear in lookbehind assertions,
+ because it makes it impossible to calculate the length of the lookbe-
+ hind. The \X and \R escapes, which can match different numbers of code
+ units, are also not permitted.
+
+ "Subroutine" calls (see below) such as (?2) or (?&X) are permitted in
+ lookbehinds, as long as the subpattern matches a fixed-length string.
+ Recursion, however, is not supported.
+
+ Possessive quantifiers can be used in conjunction with lookbehind
+ assertions to specify efficient matching of fixed-length strings at the
+ end of subject strings. Consider a simple pattern such as
+
+ abcd$
+
+ when applied to a long string that does not match. Because matching
+ proceeds from left to right, PCRE2 will look for each "a" in the sub-
+ ject and then see if what follows matches the rest of the pattern. If
+ the pattern is specified as
+
+ ^.*abcd$
+
+ the initial .* matches the entire string at first, but when this fails
+ (because there is no following "a"), it backtracks to match all but the
+ last character, then all but the last two characters, and so on. Once
+ again the search for "a" covers the entire string, from right to left,
+ so we are no better off. However, if the pattern is written as
+
+ ^.*+(?<=abcd)
+
+ there can be no backtracking for the .*+ item because of the possessive
+ quantifier; it can match only the entire string. The subsequent lookbe-
+ hind assertion does a single test on the last four characters. If it
+ fails, the match fails immediately. For long strings, this approach
+ makes a significant difference to the processing time.
+
+ Using multiple assertions
+
+ Several assertions (of any sort) may occur in succession. For example,
+
+ (?<=\d{3})(?<!999)foo
+
+ matches "foo" preceded by three digits that are not "999". Notice that
+ each of the assertions is applied independently at the same point in
+ the subject string. First there is a check that the previous three
+ characters are all digits, and then there is a check that the same
+ three characters are not "999". This pattern does not match "foo" pre-
+ ceded by six characters, the first of which are digits and the last
+ three of which are not "999". For example, it doesn't match "123abc-
+ foo". A pattern to do that is
+
+ (?<=\d{3}...)(?<!999)foo
+
+ This time the first assertion looks at the preceding six characters,
+ checking that the first three are digits, and then the second assertion
+ checks that the preceding three characters are not "999".
+
+ Assertions can be nested in any combination. For example,
+
+ (?<=(?<!foo)bar)baz
+
+ matches an occurrence of "baz" that is preceded by "bar" which in turn
+ is not preceded by "foo", while
+
+ (?<=\d{3}(?!999)...)foo
+
+ is another pattern that matches "foo" preceded by three digits and any
+ three characters that are not "999".
+
+
+CONDITIONAL SUBPATTERNS
+
+ It is possible to cause the matching process to obey a subpattern con-
+ ditionally or to choose between two alternative subpatterns, depending
+ on the result of an assertion, or whether a specific capturing subpat-
+ tern has already been matched. The two possible forms of conditional
+ subpattern are:
+
+ (?(condition)yes-pattern)
+ (?(condition)yes-pattern|no-pattern)
+
+ If the condition is satisfied, the yes-pattern is used; otherwise the
+ no-pattern (if present) is used. If there are more than two alterna-
+ tives in the subpattern, a compile-time error occurs. Each of the two
+ alternatives may itself contain nested subpatterns of any form, includ-
+ ing conditional subpatterns; the restriction to two alternatives
+ applies only at the level of the condition. This pattern fragment is an
+ example where the alternatives are complex:
+
+ (?(1) (A|B|C) | (D | (?(2)E|F) | E) )
+
+
+ There are five kinds of condition: references to subpatterns, refer-
+ ences to recursion, two pseudo-conditions called DEFINE and VERSION,
+ and assertions.
+
+ Checking for a used subpattern by number
+
+ If the text between the parentheses consists of a sequence of digits,
+ the condition is true if a capturing subpattern of that number has pre-
+ viously matched. If there is more than one capturing subpattern with
+ the same number (see the earlier section about duplicate subpattern
+ numbers), the condition is true if any of them have matched. An alter-
+ native notation is to precede the digits with a plus or minus sign. In
+ this case, the subpattern number is relative rather than absolute. The
+ most recently opened parentheses can be referenced by (?(-1), the next
+ most recent by (?(-2), and so on. Inside loops it can also make sense
+ to refer to subsequent groups. The next parentheses to be opened can be
+ referenced as (?(+1), and so on. (The value zero in any of these forms
+ is not used; it provokes a compile-time error.)
+
+ Consider the following pattern, which contains non-significant white
+ space to make it more readable (assume the PCRE2_EXTENDED option) and
+ to divide it into three parts for ease of discussion:
+
+ ( \( )? [^()]+ (?(1) \) )
+
+ The first part matches an optional opening parenthesis, and if that
+ character is present, sets it as the first captured substring. The sec-
+ ond part matches one or more characters that are not parentheses. The
+ third part is a conditional subpattern that tests whether or not the
+ first set of parentheses matched. If they did, that is, if subject
+ started with an opening parenthesis, the condition is true, and so the
+ yes-pattern is executed and a closing parenthesis is required. Other-
+ wise, since no-pattern is not present, the subpattern matches nothing.
+ In other words, this pattern matches a sequence of non-parentheses,
+ optionally enclosed in parentheses.
+
+ If you were embedding this pattern in a larger one, you could use a
+ relative reference:
+
+ ...other stuff... ( \( )? [^()]+ (?(-1) \) ) ...
+
+ This makes the fragment independent of the parentheses in the larger
+ pattern.
+
+ Checking for a used subpattern by name
+
+ Perl uses the syntax (?(<name>)...) or (?('name')...) to test for a
+ used subpattern by name. For compatibility with earlier versions of
+ PCRE1, which had this facility before Perl, the syntax (?(name)...) is
+ also recognized.
+
+ Rewriting the above example to use a named subpattern gives this:
+
+ (?<OPEN> \( )? [^()]+ (?(<OPEN>) \) )
+
+ If the name used in a condition of this kind is a duplicate, the test
+ is applied to all subpatterns of the same name, and is true if any one
+ of them has matched.
+
+ Checking for pattern recursion
+
+ If the condition is the string (R), and there is no subpattern with the
+ name R, the condition is true if a recursive call to the whole pattern
+ or any subpattern has been made. If digits or a name preceded by amper-
+ sand follow the letter R, for example:
+
+ (?(R3)...) or (?(R&name)...)
+
+ the condition is true if the most recent recursion is into a subpattern
+ whose number or name is given. This condition does not check the entire
+ recursion stack. If the name used in a condition of this kind is a
+ duplicate, the test is applied to all subpatterns of the same name, and
+ is true if any one of them is the most recent recursion.
+
+ At "top level", all these recursion test conditions are false. The
+ syntax for recursive patterns is described below.
+
+ Defining subpatterns for use by reference only
+
+ If the condition is the string (DEFINE), and there is no subpattern
+ with the name DEFINE, the condition is always false. In this case,
+ there may be only one alternative in the subpattern. It is always
+ skipped if control reaches this point in the pattern; the idea of
+ DEFINE is that it can be used to define subroutines that can be refer-
+ enced from elsewhere. (The use of subroutines is described below.) For
+ example, a pattern to match an IPv4 address such as "192.168.23.245"
+ could be written like this (ignore white space and line breaks):
+
+ (?(DEFINE) (?<byte> 2[0-4]\d | 25[0-5] | 1\d\d | [1-9]?\d) )
+ \b (?&byte) (\.(?&byte)){3} \b
+
+ The first part of the pattern is a DEFINE group inside which a another
+ group named "byte" is defined. This matches an individual component of
+ an IPv4 address (a number less than 256). When matching takes place,
+ this part of the pattern is skipped because DEFINE acts like a false
+ condition. The rest of the pattern uses references to the named group
+ to match the four dot-separated components of an IPv4 address, insist-
+ ing on a word boundary at each end.
+
+ Checking the PCRE2 version
+
+ Programs that link with a PCRE2 library can check the version by call-
+ ing pcre2_config() with appropriate arguments. Users of applications
+ that do not have access to the underlying code cannot do this. A spe-
+ cial "condition" called VERSION exists to allow such users to discover
+ which version of PCRE2 they are dealing with by using this condition to
+ match a string such as "yesno". VERSION must be followed either by "="
+ or ">=" and a version number. For example:
+
+ (?(VERSION>=10.4)yes|no)
+
+ This pattern matches "yes" if the PCRE2 version is greater or equal to
+ 10.4, or "no" otherwise. The fractional part of the version number may
+ not contain more than two digits.
+
+ Assertion conditions
+
+ If the condition is not in any of the above formats, it must be an
+ assertion. This may be a positive or negative lookahead or lookbehind
+ assertion. Consider this pattern, again containing non-significant
+ white space, and with the two alternatives on the second line:
+
+ (?(?=[^a-z]*[a-z])
+ \d{2}-[a-z]{3}-\d{2} | \d{2}-\d{2}-\d{2} )
+
+ The condition is a positive lookahead assertion that matches an
+ optional sequence of non-letters followed by a letter. In other words,
+ it tests for the presence of at least one letter in the subject. If a
+ letter is found, the subject is matched against the first alternative;
+ otherwise it is matched against the second. This pattern matches
+ strings in one of the two forms dd-aaa-dd or dd-dd-dd, where aaa are
+ letters and dd are digits.
+
+
+COMMENTS
+
+ There are two ways of including comments in patterns that are processed
+ by PCRE2. In both cases, the start of the comment must not be in a
+ character class, nor in the middle of any other sequence of related
+ characters such as (?: or a subpattern name or number. The characters
+ that make up a comment play no part in the pattern matching.
+
+ The sequence (?# marks the start of a comment that continues up to the
+ next closing parenthesis. Nested parentheses are not permitted. If the
+ PCRE2_EXTENDED option is set, an unescaped # character also introduces
+ a comment, which in this case continues to immediately after the next
+ newline character or character sequence in the pattern. Which charac-
+ ters are interpreted as newlines is controlled by an option passed to
+ the compiling function or by a special sequence at the start of the
+ pattern, as described in the section entitled "Newline conventions"
+ above. Note that the end of this type of comment is a literal newline
+ sequence in the pattern; escape sequences that happen to represent a
+ newline do not count. For example, consider this pattern when
+ PCRE2_EXTENDED is set, and the default newline convention (a single
+ linefeed character) is in force:
+
+ abc #comment \n still comment
+
+ On encountering the # character, pcre2_compile() skips along, looking
+ for a newline in the pattern. The sequence \n is still literal at this
+ stage, so it does not terminate the comment. Only an actual character
+ with the code value 0x0a (the default newline) does so.
+
+
+RECURSIVE PATTERNS
+
+ Consider the problem of matching a string in parentheses, allowing for
+ unlimited nested parentheses. Without the use of recursion, the best
+ that can be done is to use a pattern that matches up to some fixed
+ depth of nesting. It is not possible to handle an arbitrary nesting
+ depth.
+
+ For some time, Perl has provided a facility that allows regular expres-
+ sions to recurse (amongst other things). It does this by interpolating
+ Perl code in the expression at run time, and the code can refer to the
+ expression itself. A Perl pattern using code interpolation to solve the
+ parentheses problem can be created like this:
+
+ $re = qr{\( (?: (?>[^()]+) | (?p{$re}) )* \)}x;
+
+ The (?p{...}) item interpolates Perl code at run time, and in this case
+ refers recursively to the pattern in which it appears.
+
+ Obviously, PCRE2 cannot support the interpolation of Perl code.
+ Instead, it supports special syntax for recursion of the entire pat-
+ tern, and also for individual subpattern recursion. After its introduc-
+ tion in PCRE1 and Python, this kind of recursion was subsequently
+ introduced into Perl at release 5.10.
+
+ A special item that consists of (? followed by a number greater than
+ zero and a closing parenthesis is a recursive subroutine call of the
+ subpattern of the given number, provided that it occurs inside that
+ subpattern. (If not, it is a non-recursive subroutine call, which is
+ described in the next section.) The special item (?R) or (?0) is a
+ recursive call of the entire regular expression.
+
+ This PCRE2 pattern solves the nested parentheses problem (assume the
+ PCRE2_EXTENDED option is set so that white space is ignored):
+
+ \( ( [^()]++ | (?R) )* \)
+
+ First it matches an opening parenthesis. Then it matches any number of
+ substrings which can either be a sequence of non-parentheses, or a
+ recursive match of the pattern itself (that is, a correctly parenthe-
+ sized substring). Finally there is a closing parenthesis. Note the use
+ of a possessive quantifier to avoid backtracking into sequences of non-
+ parentheses.
+
+ If this were part of a larger pattern, you would not want to recurse
+ the entire pattern, so instead you could use this:
+
+ ( \( ( [^()]++ | (?1) )* \) )
+
+ We have put the pattern into parentheses, and caused the recursion to
+ refer to them instead of the whole pattern.
+
+ In a larger pattern, keeping track of parenthesis numbers can be
+ tricky. This is made easier by the use of relative references. Instead
+ of (?1) in the pattern above you can write (?-2) to refer to the second
+ most recently opened parentheses preceding the recursion. In other
+ words, a negative number counts capturing parentheses leftwards from
+ the point at which it is encountered.
+
+ Be aware however, that if duplicate subpattern numbers are in use, rel-
+ ative references refer to the earliest subpattern with the appropriate
+ number. Consider, for example:
+
+ (?|(a)|(b)) (c) (?-2)
+
+ The first two capturing groups (a) and (b) are both numbered 1, and
+ group (c) is number 2. When the reference (?-2) is encountered, the
+ second most recently opened parentheses has the number 1, but it is the
+ first such group (the (a) group) to which the recursion refers. This
+ would be the same if an absolute reference (?1) was used. In other
+ words, relative references are just a shorthand for computing a group
+ number.
+
+ It is also possible to refer to subsequently opened parentheses, by
+ writing references such as (?+2). However, these cannot be recursive
+ because the reference is not inside the parentheses that are refer-
+ enced. They are always non-recursive subroutine calls, as described in
+ the next section.
+
+ An alternative approach is to use named parentheses. The Perl syntax
+ for this is (?&name); PCRE1's earlier syntax (?P>name) is also sup-
+ ported. We could rewrite the above example as follows:
+
+ (?<pn> \( ( [^()]++ | (?&pn) )* \) )
+
+ If there is more than one subpattern with the same name, the earliest
+ one is used.
+
+ The example pattern that we have been looking at contains nested unlim-
+ ited repeats, and so the use of a possessive quantifier for matching
+ strings of non-parentheses is important when applying the pattern to
+ strings that do not match. For example, when this pattern is applied to
+
+ (aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa()
+
+ it yields "no match" quickly. However, if a possessive quantifier is
+ not used, the match runs for a very long time indeed because there are
+ so many different ways the + and * repeats can carve up the subject,
+ and all have to be tested before failure can be reported.
+
+ At the end of a match, the values of capturing parentheses are those
+ from the outermost level. If you want to obtain intermediate values, a
+ callout function can be used (see below and the pcre2callout documenta-
+ tion). If the pattern above is matched against
+
+ (ab(cd)ef)
+
+ the value for the inner capturing parentheses (numbered 2) is "ef",
+ which is the last value taken on at the top level. If a capturing sub-
+ pattern is not matched at the top level, its final captured value is
+ unset, even if it was (temporarily) set at a deeper level during the
+ matching process.
+
+ If there are more than 15 capturing parentheses in a pattern, PCRE2 has
+ to obtain extra memory from the heap to store data during a recursion.
+ If no memory can be obtained, the match fails with the
+ PCRE2_ERROR_NOMEMORY error.
+
+ Do not confuse the (?R) item with the condition (R), which tests for
+ recursion. Consider this pattern, which matches text in angle brack-
+ ets, allowing for arbitrary nesting. Only digits are allowed in nested
+ brackets (that is, when recursing), whereas any characters are permit-
+ ted at the outer level.
+
+ < (?: (?(R) \d++ | [^<>]*+) | (?R)) * >
+
+ In this pattern, (?(R) is the start of a conditional subpattern, with
+ two different alternatives for the recursive and non-recursive cases.
+ The (?R) item is the actual recursive call.
+
+ Differences in recursion processing between PCRE2 and Perl
+
+ Recursion processing in PCRE2 differs from Perl in two important ways.
+ In PCRE2 (like Python, but unlike Perl), a recursive subpattern call is
+ always treated as an atomic group. That is, once it has matched some of
+ the subject string, it is never re-entered, even if it contains untried
+ alternatives and there is a subsequent matching failure. This can be
+ illustrated by the following pattern, which purports to match a palin-
+ dromic string that contains an odd number of characters (for example,
+ "a", "aba", "abcba", "abcdcba"):
+
+ ^(.|(.)(?1)\2)$
+
+ The idea is that it either matches a single character, or two identical
+ characters surrounding a sub-palindrome. In Perl, this pattern works;
+ in PCRE2 it does not if the pattern is longer than three characters.
+ Consider the subject string "abcba":
+
+ At the top level, the first character is matched, but as it is not at
+ the end of the string, the first alternative fails; the second alterna-
+ tive is taken and the recursion kicks in. The recursive call to subpat-
+ tern 1 successfully matches the next character ("b"). (Note that the
+ beginning and end of line tests are not part of the recursion).
+
+ Back at the top level, the next character ("c") is compared with what
+ subpattern 2 matched, which was "a". This fails. Because the recursion
+ is treated as an atomic group, there are now no backtracking points,
+ and so the entire match fails. (Perl is able, at this point, to re-
+ enter the recursion and try the second alternative.) However, if the
+ pattern is written with the alternatives in the other order, things are
+ different:
+
+ ^((.)(?1)\2|.)$
+
+ This time, the recursing alternative is tried first, and continues to
+ recurse until it runs out of characters, at which point the recursion
+ fails. But this time we do have another alternative to try at the
+ higher level. That is the big difference: in the previous case the
+ remaining alternative is at a deeper recursion level, which PCRE2 can-
+ not use.
+
+ To change the pattern so that it matches all palindromic strings, not
+ just those with an odd number of characters, it is tempting to change
+ the pattern to this:
+
+ ^((.)(?1)\2|.?)$
+
+ Again, this works in Perl, but not in PCRE2, and for the same reason.
+ When a deeper recursion has matched a single character, it cannot be
+ entered again in order to match an empty string. The solution is to
+ separate the two cases, and write out the odd and even cases as alter-
+ natives at the higher level:
+
+ ^(?:((.)(?1)\2|)|((.)(?3)\4|.))
+
+ If you want to match typical palindromic phrases, the pattern has to
+ ignore all non-word characters, which can be done like this:
+
+ ^\W*+(?:((.)\W*+(?1)\W*+\2|)|((.)\W*+(?3)\W*+\4|\W*+.\W*+))\W*+$
+
+ If run with the PCRE2_CASELESS option, this pattern matches phrases
+ such as "A man, a plan, a canal: Panama!" and it works in both PCRE2
+ and Perl. Note the use of the possessive quantifier *+ to avoid back-
+ tracking into sequences of non-word characters. Without this, PCRE2
+ takes a great deal longer (ten times or more) to match typical phrases,
+ and Perl takes so long that you think it has gone into a loop.
+
+ WARNING: The palindrome-matching patterns above work only if the sub-
+ ject string does not start with a palindrome that is shorter than the
+ entire string. For example, although "abcba" is correctly matched, if
+ the subject is "ababa", PCRE2 finds the palindrome "aba" at the start,
+ then fails at top level because the end of the string does not follow.
+ Once again, it cannot jump back into the recursion to try other alter-
+ natives, so the entire match fails.
+
+ The second way in which PCRE2 and Perl differ in their recursion pro-
+ cessing is in the handling of captured values. In Perl, when a subpat-
+ tern is called recursively or as a subpattern (see the next section),
+ it has no access to any values that were captured outside the recur-
+ sion, whereas in PCRE2 these values can be referenced. Consider this
+ pattern:
+
+ ^(.)(\1|a(?2))
+
+ In PCRE2, this pattern matches "bab". The first capturing parentheses
+ match "b", then in the second group, when the back reference \1 fails
+ to match "b", the second alternative matches "a" and then recurses. In
+ the recursion, \1 does now match "b" and so the whole match succeeds.
+ In Perl, the pattern fails to match because inside the recursive call
+ \1 cannot access the externally set value.
+
+
+SUBPATTERNS AS SUBROUTINES
+
+ If the syntax for a recursive subpattern call (either by number or by
+ name) is used outside the parentheses to which it refers, it operates
+ like a subroutine in a programming language. The called subpattern may
+ be defined before or after the reference. A numbered reference can be
+ absolute or relative, as in these examples:
+
+ (...(absolute)...)...(?2)...
+ (...(relative)...)...(?-1)...
+ (...(?+1)...(relative)...
+
+ An earlier example pointed out that the pattern
+
+ (sens|respons)e and \1ibility
+
+ matches "sense and sensibility" and "response and responsibility", but
+ not "sense and responsibility". If instead the pattern
+
+ (sens|respons)e and (?1)ibility
+
+ is used, it does match "sense and responsibility" as well as the other
+ two strings. Another example is given in the discussion of DEFINE
+ above.
+
+ All subroutine calls, whether recursive or not, are always treated as
+ atomic groups. That is, once a subroutine has matched some of the sub-
+ ject string, it is never re-entered, even if it contains untried alter-
+ natives and there is a subsequent matching failure. Any capturing
+ parentheses that are set during the subroutine call revert to their
+ previous values afterwards.
+
+ Processing options such as case-independence are fixed when a subpat-
+ tern is defined, so if it is used as a subroutine, such options cannot
+ be changed for different calls. For example, consider this pattern:
+
+ (abc)(?i:(?-1))
+
+ It matches "abcabc". It does not match "abcABC" because the change of
+ processing option does not affect the called subpattern.
+
+
+ONIGURUMA SUBROUTINE SYNTAX
+
+ For compatibility with Oniguruma, the non-Perl syntax \g followed by a
+ name or a number enclosed either in angle brackets or single quotes, is
+ an alternative syntax for referencing a subpattern as a subroutine,
+ possibly recursively. Here are two of the examples used above, rewrit-
+ ten using this syntax:
+
+ (?<pn> \( ( (?>[^()]+) | \g<pn> )* \) )
+ (sens|respons)e and \g'1'ibility
+
+ PCRE2 supports an extension to Oniguruma: if a number is preceded by a
+ plus or a minus sign it is taken as a relative reference. For example:
+
+ (abc)(?i:\g<-1>)
+
+ Note that \g{...} (Perl syntax) and \g<...> (Oniguruma syntax) are not
+ synonymous. The former is a back reference; the latter is a subroutine
+ call.
+
+
+CALLOUTS
+
+ Perl has a feature whereby using the sequence (?{...}) causes arbitrary
+ Perl code to be obeyed in the middle of matching a regular expression.
+ This makes it possible, amongst other things, to extract different sub-
+ strings that match the same pair of parentheses when there is a repeti-
+ tion.
+
+ PCRE2 provides a similar feature, but of course it cannot obey arbi-
+ trary Perl code. The feature is called "callout". The caller of PCRE2
+ provides an external function by putting its entry point in a match
+ context using the function pcre2_set_callout(), and then passing that
+ context to pcre2_match() or pcre2_dfa_match(). If no match context is
+ passed, or if the callout entry point is set to NULL, callouts are dis-
+ abled.
+
+ Within a regular expression, (?C<arg>) indicates a point at which the
+ external function is to be called. There are two kinds of callout:
+ those with a numerical argument and those with a string argument. (?C)
+ on its own with no argument is treated as (?C0). A numerical argument
+ allows the application to distinguish between different callouts.
+ String arguments were added for release 10.20 to make it possible for
+ script languages that use PCRE2 to embed short scripts within patterns
+ in a similar way to Perl.
+
+ During matching, when PCRE2 reaches a callout point, the external func-
+ tion is called. It is provided with the number or string argument of
+ the callout, the position in the pattern, and one item of data that is
+ also set in the match block. The callout function may cause matching to
+ proceed, to backtrack, or to fail.
+
+ By default, PCRE2 implements a number of optimizations at matching
+ time, and one side-effect is that sometimes callouts are skipped. If
+ you need all possible callouts to happen, you need to set options that
+ disable the relevant optimizations. More details, including a complete
+ description of the programming interface to the callout function, are
+ given in the pcre2callout documentation.
+
+ Callouts with numerical arguments
+
+ If you just want to have a means of identifying different callout
+ points, put a number less than 256 after the letter C. For example,
+ this pattern has two callout points:
+
+ (?C1)abc(?C2)def
+
+ If the PCRE2_AUTO_CALLOUT flag is passed to pcre2_compile(), numerical
+ callouts are automatically installed before each item in the pattern.
+ They are all numbered 255. If there is a conditional group in the pat-
+ tern whose condition is an assertion, an additional callout is inserted
+ just before the condition. An explicit callout may also be set at this
+ position, as in this example:
+
+ (?(?C9)(?=a)abc|def)
+
+ Note that this applies only to assertion conditions, not to other types
+ of condition.
+
+ Callouts with string arguments
+
+ A delimited string may be used instead of a number as a callout argu-
+ ment. The starting delimiter must be one of ` ' " ^ % # $ { and the
+ ending delimiter is the same as the start, except for {, where the end-
+ ing delimiter is }. If the ending delimiter is needed within the
+ string, it must be doubled. For example:
+
+ (?C'ab ''c'' d')xyz(?C{any text})pqr
+
+ The doubling is removed before the string is passed to the callout
+ function.
+
+
+BACKTRACKING CONTROL
+
+ Perl 5.10 introduced a number of "Special Backtracking Control Verbs",
+ which are still described in the Perl documentation as "experimental
+ and subject to change or removal in a future version of Perl". It goes
+ on to say: "Their usage in production code should be noted to avoid
+ problems during upgrades." The same remarks apply to the PCRE2 features
+ described in this section.
+
+ The new verbs make use of what was previously invalid syntax: an open-
+ ing parenthesis followed by an asterisk. They are generally of the form
+ (*VERB) or (*VERB:NAME). Some verbs take either form, possibly behaving
+ differently depending on whether or not a name is present.
+
+ By default, for compatibility with Perl, a name is any sequence of
+ characters that does not include a closing parenthesis. The name is not
+ processed in any way, and it is not possible to include a closing
+ parenthesis in the name. However, if the PCRE2_ALT_VERBNAMES option is
+ set, normal backslash processing is applied to verb names and only an
+ unescaped closing parenthesis terminates the name. A closing parenthe-
+ sis can be included in a name either as \) or between \Q and \E. If the
+ PCRE2_EXTENDED option is set, unescaped whitespace in verb names is
+ skipped and #-comments are recognized, exactly as in the rest of the
+ pattern.
+
+ The maximum length of a name is 255 in the 8-bit library and 65535 in
+ the 16-bit and 32-bit libraries. If the name is empty, that is, if the
+ closing parenthesis immediately follows the colon, the effect is as if
+ the colon were not there. Any number of these verbs may occur in a pat-
+ tern.
+
+ Since these verbs are specifically related to backtracking, most of
+ them can be used only when the pattern is to be matched using the tra-
+ ditional matching function, because these use a backtracking algorithm.
+ With the exception of (*FAIL), which behaves like a failing negative
+ assertion, the backtracking control verbs cause an error if encountered
+ by the DFA matching function.
+
+ The behaviour of these verbs in repeated groups, assertions, and in
+ subpatterns called as subroutines (whether or not recursively) is docu-
+ mented below.
+
+ Optimizations that affect backtracking verbs
+
+ PCRE2 contains some optimizations that are used to speed up matching by
+ running some checks at the start of each match attempt. For example, it
+ may know the minimum length of matching subject, or that a particular
+ character must be present. When one of these optimizations bypasses the
+ running of a match, any included backtracking verbs will not, of
+ course, be processed. You can suppress the start-of-match optimizations
+ by setting the PCRE2_NO_START_OPTIMIZE option when calling pcre2_com-
+ pile(), or by starting the pattern with (*NO_START_OPT). There is more
+ discussion of this option in the section entitled "Compiling a pattern"
+ in the pcre2api documentation.
+
+ Experiments with Perl suggest that it too has similar optimizations,
+ sometimes leading to anomalous results.
+
+ Verbs that act immediately
+
+ The following verbs act as soon as they are encountered. They may not
+ be followed by a name.
+
+ (*ACCEPT)
+
+ This verb causes the match to end successfully, skipping the remainder
+ of the pattern. However, when it is inside a subpattern that is called
+ as a subroutine, only that subpattern is ended successfully. Matching
+ then continues at the outer level. If (*ACCEPT) in triggered in a posi-
+ tive assertion, the assertion succeeds; in a negative assertion, the
+ assertion fails.
+
+ If (*ACCEPT) is inside capturing parentheses, the data so far is cap-
+ tured. For example:
+
+ A((?:A|B(*ACCEPT)|C)D)
+
+ This matches "AB", "AAD", or "ACD"; when it matches "AB", "B" is cap-
+ tured by the outer parentheses.
+
+ (*FAIL) or (*F)
+
+ This verb causes a matching failure, forcing backtracking to occur. It
+ is equivalent to (?!) but easier to read. The Perl documentation notes
+ that it is probably useful only when combined with (?{}) or (??{}).
+ Those are, of course, Perl features that are not present in PCRE2. The
+ nearest equivalent is the callout feature, as for example in this pat-
+ tern:
+
+ a+(?C)(*FAIL)
+
+ A match with the string "aaaa" always fails, but the callout is taken
+ before each backtrack happens (in this example, 10 times).
+
+ Recording which path was taken
+
+ There is one verb whose main purpose is to track how a match was
+ arrived at, though it also has a secondary use in conjunction with
+ advancing the match starting point (see (*SKIP) below).
+
+ (*MARK:NAME) or (*:NAME)
+
+ A name is always required with this verb. There may be as many
+ instances of (*MARK) as you like in a pattern, and their names do not
+ have to be unique.
+
+ When a match succeeds, the name of the last-encountered (*MARK:NAME),
+ (*PRUNE:NAME), or (*THEN:NAME) on the matching path is passed back to
+ the caller as described in the section entitled "Other information
+ about the match" in the pcre2api documentation. Here is an example of
+ pcre2test output, where the "mark" modifier requests the retrieval and
+ outputting of (*MARK) data:
+
+ re> /X(*MARK:A)Y|X(*MARK:B)Z/mark
+ data> XY
+ 0: XY
+ MK: A
+ XZ
+ 0: XZ
+ MK: B
+
+ The (*MARK) name is tagged with "MK:" in this output, and in this exam-
+ ple it indicates which of the two alternatives matched. This is a more
+ efficient way of obtaining this information than putting each alterna-
+ tive in its own capturing parentheses.
+
+ If a verb with a name is encountered in a positive assertion that is
+ true, the name is recorded and passed back if it is the last-encoun-
+ tered. This does not happen for negative assertions or failing positive
+ assertions.
+
+ After a partial match or a failed match, the last encountered name in
+ the entire match process is returned. For example:
+
+ re> /X(*MARK:A)Y|X(*MARK:B)Z/mark
+ data> XP
+ No match, mark = B
+
+ Note that in this unanchored example the mark is retained from the
+ match attempt that started at the letter "X" in the subject. Subsequent
+ match attempts starting at "P" and then with an empty string do not get
+ as far as the (*MARK) item, but nevertheless do not reset it.
+
+ If you are interested in (*MARK) values after failed matches, you
+ should probably set the PCRE2_NO_START_OPTIMIZE option (see above) to
+ ensure that the match is always attempted.
+
+ Verbs that act after backtracking
+
+ The following verbs do nothing when they are encountered. Matching con-
+ tinues with what follows, but if there is no subsequent match, causing
+ a backtrack to the verb, a failure is forced. That is, backtracking
+ cannot pass to the left of the verb. However, when one of these verbs
+ appears inside an atomic group (which includes any group that is called
+ as a subroutine) or in an assertion that is true, its effect is con-
+ fined to that group, because once the group has been matched, there is
+ never any backtracking into it. In this situation, backtracking has to
+ jump to the left of the entire atomic group or assertion.
+
+ These verbs differ in exactly what kind of failure occurs when back-
+ tracking reaches them. The behaviour described below is what happens
+ when the verb is not in a subroutine or an assertion. Subsequent sec-
+ tions cover these special cases.
+
+ (*COMMIT)
+
+ This verb, which may not be followed by a name, causes the whole match
+ to fail outright if there is a later matching failure that causes back-
+ tracking to reach it. Even if the pattern is unanchored, no further
+ attempts to find a match by advancing the starting point take place. If
+ (*COMMIT) is the only backtracking verb that is encountered, once it
+ has been passed pcre2_match() is committed to finding a match at the
+ current starting point, or not at all. For example:
+
+ a+(*COMMIT)b
+
+ This matches "xxaab" but not "aacaab". It can be thought of as a kind
+ of dynamic anchor, or "I've started, so I must finish." The name of the
+ most recently passed (*MARK) in the path is passed back when (*COMMIT)
+ forces a match failure.
+
+ If there is more than one backtracking verb in a pattern, a different
+ one that follows (*COMMIT) may be triggered first, so merely passing
+ (*COMMIT) during a match does not always guarantee that a match must be
+ at this starting point.
+
+ Note that (*COMMIT) at the start of a pattern is not the same as an
+ anchor, unless PCRE2's start-of-match optimizations are turned off, as
+ shown in this output from pcre2test:
+
+ re> /(*COMMIT)abc/
+ data> xyzabc
+ 0: abc
+ data>
+ re> /(*COMMIT)abc/no_start_optimize
+ data> xyzabc
+ No match
+
+ For the first pattern, PCRE2 knows that any match must start with "a",
+ so the optimization skips along the subject to "a" before applying the
+ pattern to the first set of data. The match attempt then succeeds. The
+ second pattern disables the optimization that skips along to the first
+ character. The pattern is now applied starting at "x", and so the
+ (*COMMIT) causes the match to fail without trying any other starting
+ points.
+
+ (*PRUNE) or (*PRUNE:NAME)
+
+ This verb causes the match to fail at the current starting position in
+ the subject if there is a later matching failure that causes backtrack-
+ ing to reach it. If the pattern is unanchored, the normal "bumpalong"
+ advance to the next starting character then happens. Backtracking can
+ occur as usual to the left of (*PRUNE), before it is reached, or when
+ matching to the right of (*PRUNE), but if there is no match to the
+ right, backtracking cannot cross (*PRUNE). In simple cases, the use of
+ (*PRUNE) is just an alternative to an atomic group or possessive quan-
+ tifier, but there are some uses of (*PRUNE) that cannot be expressed in
+ any other way. In an anchored pattern (*PRUNE) has the same effect as
+ (*COMMIT).
+
+ The behaviour of (*PRUNE:NAME) is the not the same as
+ (*MARK:NAME)(*PRUNE). It is like (*MARK:NAME) in that the name is
+ remembered for passing back to the caller. However, (*SKIP:NAME)
+ searches only for names set with (*MARK), ignoring those set by
+ (*PRUNE) or (*THEN).
+
+ (*SKIP)
+
+ This verb, when given without a name, is like (*PRUNE), except that if
+ the pattern is unanchored, the "bumpalong" advance is not to the next
+ character, but to the position in the subject where (*SKIP) was encoun-
+ tered. (*SKIP) signifies that whatever text was matched leading up to
+ it cannot be part of a successful match. Consider:
+
+ a+(*SKIP)b
+
+ If the subject is "aaaac...", after the first match attempt fails
+ (starting at the first character in the string), the starting point
+ skips on to start the next attempt at "c". Note that a possessive quan-
+ tifer does not have the same effect as this example; although it would
+ suppress backtracking during the first match attempt, the second
+ attempt would start at the second character instead of skipping on to
+ "c".
+
+ (*SKIP:NAME)
+
+ When (*SKIP) has an associated name, its behaviour is modified. When it
+ is triggered, the previous path through the pattern is searched for the
+ most recent (*MARK) that has the same name. If one is found, the
+ "bumpalong" advance is to the subject position that corresponds to that
+ (*MARK) instead of to where (*SKIP) was encountered. If no (*MARK) with
+ a matching name is found, the (*SKIP) is ignored.
+
+ Note that (*SKIP:NAME) searches only for names set by (*MARK:NAME). It
+ ignores names that are set by (*PRUNE:NAME) or (*THEN:NAME).
+
+ (*THEN) or (*THEN:NAME)
+
+ This verb causes a skip to the next innermost alternative when back-
+ tracking reaches it. That is, it cancels any further backtracking
+ within the current alternative. Its name comes from the observation
+ that it can be used for a pattern-based if-then-else block:
+
+ ( COND1 (*THEN) FOO | COND2 (*THEN) BAR | COND3 (*THEN) BAZ ) ...
+
+ If the COND1 pattern matches, FOO is tried (and possibly further items
+ after the end of the group if FOO succeeds); on failure, the matcher
+ skips to the second alternative and tries COND2, without backtracking
+ into COND1. If that succeeds and BAR fails, COND3 is tried. If subse-
+ quently BAZ fails, there are no more alternatives, so there is a back-
+ track to whatever came before the entire group. If (*THEN) is not
+ inside an alternation, it acts like (*PRUNE).
+
+ The behaviour of (*THEN:NAME) is the not the same as
+ (*MARK:NAME)(*THEN). It is like (*MARK:NAME) in that the name is
+ remembered for passing back to the caller. However, (*SKIP:NAME)
+ searches only for names set with (*MARK), ignoring those set by
+ (*PRUNE) and (*THEN).
+
+ A subpattern that does not contain a | character is just a part of the
+ enclosing alternative; it is not a nested alternation with only one
+ alternative. The effect of (*THEN) extends beyond such a subpattern to
+ the enclosing alternative. Consider this pattern, where A, B, etc. are
+ complex pattern fragments that do not contain any | characters at this
+ level:
+
+ A (B(*THEN)C) | D
+
+ If A and B are matched, but there is a failure in C, matching does not
+ backtrack into A; instead it moves to the next alternative, that is, D.
+ However, if the subpattern containing (*THEN) is given an alternative,
+ it behaves differently:
+
+ A (B(*THEN)C | (*FAIL)) | D
+
+ The effect of (*THEN) is now confined to the inner subpattern. After a
+ failure in C, matching moves to (*FAIL), which causes the whole subpat-
+ tern to fail because there are no more alternatives to try. In this
+ case, matching does now backtrack into A.
+
+ Note that a conditional subpattern is not considered as having two
+ alternatives, because only one is ever used. In other words, the |
+ character in a conditional subpattern has a different meaning. Ignoring
+ white space, consider:
+
+ ^.*? (?(?=a) a | b(*THEN)c )
+
+ If the subject is "ba", this pattern does not match. Because .*? is
+ ungreedy, it initially matches zero characters. The condition (?=a)
+ then fails, the character "b" is matched, but "c" is not. At this
+ point, matching does not backtrack to .*? as might perhaps be expected
+ from the presence of the | character. The conditional subpattern is
+ part of the single alternative that comprises the whole pattern, and so
+ the match fails. (If there was a backtrack into .*?, allowing it to
+ match "b", the match would succeed.)
+
+ The verbs just described provide four different "strengths" of control
+ when subsequent matching fails. (*THEN) is the weakest, carrying on the
+ match at the next alternative. (*PRUNE) comes next, failing the match
+ at the current starting position, but allowing an advance to the next
+ character (for an unanchored pattern). (*SKIP) is similar, except that
+ the advance may be more than one character. (*COMMIT) is the strongest,
+ causing the entire match to fail.
+
+ More than one backtracking verb
+
+ If more than one backtracking verb is present in a pattern, the one
+ that is backtracked onto first acts. For example, consider this pat-
+ tern, where A, B, etc. are complex pattern fragments:
+
+ (A(*COMMIT)B(*THEN)C|ABD)
+
+ If A matches but B fails, the backtrack to (*COMMIT) causes the entire
+ match to fail. However, if A and B match, but C fails, the backtrack to
+ (*THEN) causes the next alternative (ABD) to be tried. This behaviour
+ is consistent, but is not always the same as Perl's. It means that if
+ two or more backtracking verbs appear in succession, all the the last
+ of them has no effect. Consider this example:
+
+ ...(*COMMIT)(*PRUNE)...
+
+ If there is a matching failure to the right, backtracking onto (*PRUNE)
+ causes it to be triggered, and its action is taken. There can never be
+ a backtrack onto (*COMMIT).
+
+ Backtracking verbs in repeated groups
+
+ PCRE2 differs from Perl in its handling of backtracking verbs in
+ repeated groups. For example, consider:
+
+ /(a(*COMMIT)b)+ac/
+
+ If the subject is "abac", Perl matches, but PCRE2 fails because the
+ (*COMMIT) in the second repeat of the group acts.
+
+ Backtracking verbs in assertions
+
+ (*FAIL) in an assertion has its normal effect: it forces an immediate
+ backtrack.
+
+ (*ACCEPT) in a positive assertion causes the assertion to succeed with-
+ out any further processing. In a negative assertion, (*ACCEPT) causes
+ the assertion to fail without any further processing.
+
+ The other backtracking verbs are not treated specially if they appear
+ in a positive assertion. In particular, (*THEN) skips to the next
+ alternative in the innermost enclosing group that has alternations,
+ whether or not this is within the assertion.
+
+ Negative assertions are, however, different, in order to ensure that
+ changing a positive assertion into a negative assertion changes its
+ result. Backtracking into (*COMMIT), (*SKIP), or (*PRUNE) causes a neg-
+ ative assertion to be true, without considering any further alternative
+ branches in the assertion. Backtracking into (*THEN) causes it to skip
+ to the next enclosing alternative within the assertion (the normal be-
+ haviour), but if the assertion does not have such an alternative,
+ (*THEN) behaves like (*PRUNE).
+
+ Backtracking verbs in subroutines
+
+ These behaviours occur whether or not the subpattern is called recur-
+ sively. Perl's treatment of subroutines is different in some cases.
+
+ (*FAIL) in a subpattern called as a subroutine has its normal effect:
+ it forces an immediate backtrack.
+
+ (*ACCEPT) in a subpattern called as a subroutine causes the subroutine
+ match to succeed without any further processing. Matching then contin-
+ ues after the subroutine call.
+
+ (*COMMIT), (*SKIP), and (*PRUNE) in a subpattern called as a subroutine
+ cause the subroutine match to fail.
+
+ (*THEN) skips to the next alternative in the innermost enclosing group
+ within the subpattern that has alternatives. If there is no such group
+ within the subpattern, (*THEN) causes the subroutine match to fail.

+
+
+NAME
+ PCRE2 - Perl-compatible regular expressions (revised API)
+
+PCRE2 PERFORMANCE
+
+ Two aspects of performance are discussed below: memory usage and pro-
+ cessing time. The way you express your pattern as a regular expression
+ can affect both of them.
+
+
+COMPILED PATTERN MEMORY USAGE
+
+ Patterns are compiled by PCRE2 into a reasonably efficient interpretive
+ code, so that most simple patterns do not use much memory. However,
+ there is one case where the memory usage of a compiled pattern can be
+ unexpectedly large. If a parenthesized subpattern has a quantifier with
+ a minimum greater than 1 and/or a limited maximum, the whole subpattern
+ is repeated in the compiled code. For example, the pattern
+
+ (abc|def){2,4}
+
+ is compiled as if it were
+
+ (abc|def)(abc|def)((abc|def)(abc|def)?)?
+
+ (Technical aside: It is done this way so that backtrack points within
+ each of the repetitions can be independently maintained.)
+
+ For regular expressions whose quantifiers use only small numbers, this
+ is not usually a problem. However, if the numbers are large, and par-
+ ticularly if such repetitions are nested, the memory usage can become
+ an embarrassment. For example, the very simple pattern
+
+ ((ab){1,1000}c){1,3}
+
+ uses 51K bytes when compiled using the 8-bit library. When PCRE2 is
+ compiled with its default internal pointer size of two bytes, the size
+ limit on a compiled pattern is 64K code units in the 8-bit and 16-bit
+ libraries, and this is reached with the above pattern if the outer rep-
+ etition is increased from 3 to 4. PCRE2 can be compiled to use larger
+ internal pointers and thus handle larger compiled patterns, but it is
+ better to try to rewrite your pattern to use less memory if you can.
+
+ One way of reducing the memory usage for such patterns is to make use
+ of PCRE2's "subroutine" facility. Re-writing the above pattern as
+
+ ((ab)(?2){0,999}c)(?1){0,2}
+
+ reduces the memory requirements to 18K, and indeed it remains under 20K
+ even with the outer repetition increased to 100. However, this pattern
+ is not exactly equivalent, because the "subroutine" calls are treated
+ as atomic groups into which there can be no backtracking if there is a
+ subsequent matching failure. Therefore, PCRE2 cannot do this kind of
+ rewriting automatically. Furthermore, there is a noticeable loss of
+ speed when executing the modified pattern. Nevertheless, if the atomic
+ grouping is not a problem and the loss of speed is acceptable, this
+ kind of rewriting will allow you to process patterns that PCRE2 cannot
+ otherwise handle.
+
+
+STACK USAGE AT RUN TIME
+
+ When pcre2_match() is used for matching, certain kinds of pattern can
+ cause it to use large amounts of the process stack. In some environ-
+ ments the default process stack is quite small, and if it runs out the
+ result is often SIGSEGV. Rewriting your pattern can often help. The
+ pcre2stack documentation discusses this issue in detail.
+
+
+PROCESSING TIME
+
+ Certain items in regular expression patterns are processed more effi-
+ ciently than others. It is more efficient to use a character class like
+ [aeiou] than a set of single-character alternatives such as
+ (a|e|i|o|u). In general, the simplest construction that provides the
+ required behaviour is usually the most efficient. Jeffrey Friedl's book
+ contains a lot of useful general discussion about optimizing regular
+ expressions for efficient performance. This document contains a few
+ observations about PCRE2.
+
+ Using Unicode character properties (the \p, \P, and \X escapes) is
+ slow, because PCRE2 has to use a multi-stage table lookup whenever it
+ needs a character's property. If you can find an alternative pattern
+ that does not use character properties, it will probably be faster.
+
+ By default, the escape sequences \b, \d, \s, and \w, and the POSIX
+ character classes such as [:alpha:] do not use Unicode properties,
+ partly for backwards compatibility, and partly for performance reasons.
+ However, you can set the PCRE2_UCP option or start the pattern with
+ (*UCP) if you want Unicode character properties to be used. This can
+ double the matching time for items such as \d, when matched with
+ pcre2_match(); the performance loss is less with a DFA matching func-
+ tion, and in both cases there is not much difference for \b.
+
+ When a pattern begins with .* not in atomic parentheses, nor in paren-
+ theses that are the subject of a backreference, and the PCRE2_DOTALL
+ option is set, the pattern is implicitly anchored by PCRE2, since it
+ can match only at the start of a subject string. If the pattern has
+ multiple top-level branches, they must all be anchorable. The optimiza-
+ tion can be disabled by the PCRE2_NO_DOTSTAR_ANCHOR option, and is
+ automatically disabled if the pattern contains (*PRUNE) or (*SKIP).
+
+ If PCRE2_DOTALL is not set, PCRE2 cannot make this optimization,
+ because the dot metacharacter does not then match a newline, and if the
+ subject string contains newlines, the pattern may match from the char-
+ acter immediately following one of them instead of from the very start.
+ For example, the pattern
+
+ .*second
+
+ matches the subject "first\nand second" (where \n stands for a newline
+ character), with the match starting at the seventh character. In order
+ to do this, PCRE2 has to retry the match starting after every newline
+ in the subject.
+
+ If you are using such a pattern with subject strings that do not con-
+ tain newlines, the best performance is obtained by setting
+ PCRE2_DOTALL, or starting the pattern with ^.* or ^.*? to indicate
+ explicit anchoring. That saves PCRE2 from having to scan along the sub-
+ ject looking for a newline to restart at.
+
+ Beware of patterns that contain nested indefinite repeats. These can
+ take a long time to run when applied to a string that does not match.
+ Consider the pattern fragment
+
+ ^(a+)*
+
+ This can match "aaaa" in 16 different ways, and this number increases
+ very rapidly as the string gets longer. (The * repeat can match 0, 1,
+ 2, 3, or 4 times, and for each of those cases other than 0 or 4, the +
+ repeats can match different numbers of times.) When the remainder of
+ the pattern is such that the entire match is going to fail, PCRE2 has
+ in principle to try every possible variation, and this can take an
+ extremely long time, even for relatively short strings.
+
+ An optimization catches some of the more simple cases such as
+
+ (a+)*b
+
+ where a literal character follows. Before embarking on the standard
+ matching procedure, PCRE2 checks that there is a "b" later in the sub-
+ ject string, and if there is not, it fails the match immediately. How-
+ ever, when there is no following literal this optimization cannot be
+ used. You can see the difference by comparing the behaviour of
+
+ (a+)*\d
+
+ with the pattern above. The former gives a failure almost instantly
+ when applied to a whole line of "a" characters, whereas the latter
+ takes an appreciable time with strings longer than about 20 characters.
+
+ In many cases, the solution to this kind of performance issue is to use
+ an atomic group or a possessive quantifier.

+
+
+DESCRIPTION
+
+ This set of functions provides a POSIX-style API for the PCRE2 regular
+ expression 8-bit library. See the pcre2api documentation for a descrip-
+ tion of PCRE2's native API, which contains much additional functional-
+ ity. There is no POSIX-style wrapper for PCRE2's 16-bit and 32-bit
+ libraries.
+
+ The functions described here are just wrapper functions that ultimately
+ call the PCRE2 native API. Their prototypes are defined in the
+ pcre2posix.h header file, and on Unix systems the library itself is
+ called libpcre2-posix.a, so can be accessed by adding -lpcre2-posix to
+ the command for linking an application that uses them. Because the
+ POSIX functions call the native ones, it is also necessary to add
+ -lpcre2-8.
+
+ Those POSIX option bits that can reasonably be mapped to PCRE2 native
+ options have been implemented. In addition, the option REG_EXTENDED is
+ defined with the value zero. This has no effect, but since programs
+ that are written to the POSIX interface often use it, this makes it
+ easier to slot in PCRE2 as a replacement library. Other POSIX options
+ are not even defined.
+
+ There are also some other options that are not defined by POSIX. These
+ have been added at the request of users who want to make use of certain
+ PCRE2-specific features via the POSIX calling interface.
+
+ When PCRE2 is called via these functions, it is only the API that is
+ POSIX-like in style. The syntax and semantics of the regular expres-
+ sions themselves are still those of Perl, subject to the setting of
+ various PCRE2 options, as described below. "POSIX-like in style" means
+ that the API approximates to the POSIX definition; it is not fully
+ POSIX-compatible, and in multi-unit encoding domains it is probably
+ even less compatible.
+
+ The header for these functions is supplied as pcre2posix.h to avoid any
+ potential clash with other POSIX libraries. It can, of course, be
+ renamed or aliased as regex.h, which is the "correct" name. It provides
+ two structure types, regex_t for compiled internal forms, and reg-
+ match_t for returning captured substrings. It also defines some con-
+ stants whose names start with "REG_"; these are used for setting
+ options and identifying error codes.
+
+
+COMPILING A PATTERN
+
+ The function regcomp() is called to compile a pattern into an internal
+ form. The pattern is a C string terminated by a binary zero, and is
+ passed in the argument pattern. The preg argument is a pointer to a
+ regex_t structure that is used as a base for storing information about
+ the compiled regular expression.
+
+ The argument cflags is either zero, or contains one or more of the bits
+ defined by the following macros:
+
+ REG_DOTALL
+
+ The PCRE2_DOTALL option is set when the regular expression is passed
+ for compilation to the native function. Note that REG_DOTALL is not
+ part of the POSIX standard.
+
+ REG_ICASE
+
+ The PCRE2_CASELESS option is set when the regular expression is passed
+ for compilation to the native function.
+
+ REG_NEWLINE
+
+ The PCRE2_MULTILINE option is set when the regular expression is passed
+ for compilation to the native function. Note that this does not mimic
+ the defined POSIX behaviour for REG_NEWLINE (see the following sec-
+ tion).
+
+ REG_NOSUB
+
+ The PCRE2_NO_AUTO_CAPTURE option is set when the regular expression is
+ passed for compilation to the native function. In addition, when a pat-
+ tern that is compiled with this flag is passed to regexec() for match-
+ ing, the nmatch and pmatch arguments are ignored, and no captured
+ strings are returned.
+
+ REG_UCP
+
+ The PCRE2_UCP option is set when the regular expression is passed for
+ compilation to the native function. This causes PCRE2 to use Unicode
+ properties when matchine \d, \w, etc., instead of just recognizing
+ ASCII values. Note that REG_UCP is not part of the POSIX standard.
+
+ REG_UNGREEDY
+
+ The PCRE2_UNGREEDY option is set when the regular expression is passed
+ for compilation to the native function. Note that REG_UNGREEDY is not
+ part of the POSIX standard.
+
+ REG_UTF
+
+ The PCRE2_UTF option is set when the regular expression is passed for
+ compilation to the native function. This causes the pattern itself and
+ all data strings used for matching it to be treated as UTF-8 strings.
+ Note that REG_UTF is not part of the POSIX standard.
+
+ In the absence of these flags, no options are passed to the native
+ function. This means the the regex is compiled with PCRE2 default
+ semantics. In particular, the way it handles newline characters in the
+ subject string is the Perl way, not the POSIX way. Note that setting
+ PCRE2_MULTILINE has only some of the effects specified for REG_NEWLINE.
+ It does not affect the way newlines are matched by the dot metacharac-
+ ter (they are not) or by a negative class such as [^a] (they are).
+
+ The yield of regcomp() is zero on success, and non-zero otherwise. The
+ preg structure is filled in on success, and one member of the structure
+ is public: re_nsub contains the number of capturing subpatterns in the
+ regular expression. Various error codes are defined in the header file.
+
+ NOTE: If the yield of regcomp() is non-zero, you must not attempt to
+ use the contents of the preg structure. If, for example, you pass it to
+ regexec(), the result is undefined and your program is likely to crash.
+
+
+MATCHING NEWLINE CHARACTERS
+
+ This area is not simple, because POSIX and Perl take different views of
+ things. It is not possible to get PCRE2 to obey POSIX semantics, but
+ then PCRE2 was never intended to be a POSIX engine. The following table
+ lists the different possibilities for matching newline characters in
+ Perl and PCRE2:
+
+ Default Change with
+
+ . matches newline no PCRE2_DOTALL
+ newline matches [^a] yes not changeable
+ $ matches \n at end yes PCRE2_DOLLAR_ENDONLY
+ $ matches \n in middle no PCRE2_MULTILINE
+ ^ matches \n in middle no PCRE2_MULTILINE
+
+ This is the equivalent table for a POSIX-compatible pattern matcher:
+
+ Default Change with
+
+ . matches newline yes REG_NEWLINE
+ newline matches [^a] yes REG_NEWLINE
+ $ matches \n at end no REG_NEWLINE
+ $ matches \n in middle no REG_NEWLINE
+ ^ matches \n in middle no REG_NEWLINE
+
+ This behaviour is not what happens when PCRE2 is called via its POSIX
+ API. By default, PCRE2's behaviour is the same as Perl's, except that
+ there is no equivalent for PCRE2_DOLLAR_ENDONLY in Perl. In both PCRE2
+ and Perl, there is no way to stop newline from matching [^a].
+
+ Default POSIX newline handling can be obtained by setting PCRE2_DOTALL
+ and PCRE2_DOLLAR_ENDONLY when calling pcre2_compile() directly, but
+ there is no way to make PCRE2 behave exactly as for the REG_NEWLINE
+ action. When using the POSIX API, passing REG_NEWLINE to PCRE2's reg-
+ comp() function causes PCRE2_MULTILINE to be passed to pcre2_compile(),
+ and REG_DOTALL passes PCRE2_DOTALL. There is no way to pass PCRE2_DOL-
+ LAR_ENDONLY.
+
+
+MATCHING A PATTERN
+
+ The function regexec() is called to match a compiled pattern preg
+ against a given string, which is by default terminated by a zero byte
+ (but see REG_STARTEND below), subject to the options in eflags. These
+ can be:
+
+ REG_NOTBOL
+
+ The PCRE2_NOTBOL option is set when calling the underlying PCRE2 match-
+ ing function.
+
+ REG_NOTEMPTY
+
+ The PCRE2_NOTEMPTY option is set when calling the underlying PCRE2
+ matching function. Note that REG_NOTEMPTY is not part of the POSIX
+ standard. However, setting this option can give more POSIX-like behav-
+ iour in some situations.
+
+ REG_NOTEOL
+
+ The PCRE2_NOTEOL option is set when calling the underlying PCRE2 match-
+ ing function.
+
+ REG_STARTEND
+
+ The string is considered to start at string + pmatch[0].rm_so and to
+ have a terminating NUL located at string + pmatch[0].rm_eo (there need
+ not actually be a NUL at that location), regardless of the value of
+ nmatch. This is a BSD extension, compatible with but not specified by
+ IEEE Standard 1003.2 (POSIX.2), and should be used with caution in
+ software intended to be portable to other systems. Note that a non-zero
+ rm_so does not imply REG_NOTBOL; REG_STARTEND affects only the location
+ of the string, not how it is matched. Setting REG_STARTEND and passing
+ pmatch as NULL are mutually exclusive; the error REG_INVARG is
+ returned.
+
+ If the pattern was compiled with the REG_NOSUB flag, no data about any
+ matched strings is returned. The nmatch and pmatch arguments of
+ regexec() are ignored.
+
+ If the value of nmatch is zero, or if the value pmatch is NULL, no data
+ about any matched strings is returned.
+
+ Otherwise,the portion of the string that was matched, and also any cap-
+ tured substrings, are returned via the pmatch argument, which points to
+ an array of nmatch structures of type regmatch_t, containing the mem-
+ bers rm_so and rm_eo. These contain the byte offset to the first char-
+ acter of each substring and the offset to the first character after the
+ end of each substring, respectively. The 0th element of the vector
+ relates to the entire portion of string that was matched; subsequent
+ elements relate to the capturing subpatterns of the regular expression.
+ Unused entries in the array have both structure members set to -1.
+
+ A successful match yields a zero return; various error codes are
+ defined in the header file, of which REG_NOMATCH is the "expected"
+ failure code.
+
+
+ERROR MESSAGES
+
+ The regerror() function maps a non-zero errorcode from either regcomp()
+ or regexec() to a printable message. If preg is not NULL, the error
+ should have arisen from the use of that structure. A message terminated
+ by a binary zero is placed in errbuf. If the buffer is too short, only
+ the first errbuf_size - 1 characters of the error message are used. The
+ yield of the function is the size of buffer needed to hold the whole
+ message, including the terminating zero. This value is greater than
+ errbuf_size if the message was truncated.
+
+
+MEMORY USAGE
+
+ Compiling a regular expression causes memory to be allocated and asso-
+ ciated with the preg structure. The function regfree() frees all such
+ memory, after which preg may no longer be used as a compiled expres-
+ sion.

+
+PCRE2 SAMPLE PROGRAM
+
+ A simple, complete demonstration program to get you started with using
+ PCRE2 is supplied in the file pcre2demo.c in the src directory in the
+ PCRE2 distribution. A listing of this program is given in the pcre2demo
+ documentation. If you do not have a copy of the PCRE2 distribution, you
+ can save this listing to re-create the contents of pcre2demo.c.
+
+ The demonstration program, which uses the PCRE2 8-bit library, compiles
+ the regular expression that is its first argument, and matches it
+ against the subject string in its second argument. No PCRE2 options are
+ set, and default character tables are used. If matching succeeds, the
+ program outputs the portion of the subject that matched, together with
+ the contents of any captured substrings.
+
+ If the -g option is given on the command line, the program then goes on
+ to check for further matches of the same regular expression in the same
+ subject string. The logic is a little bit tricky because of the possi-
+ bility of matching an empty string. Comments in the code explain what
+ is going on.
+
+ If PCRE2 is installed in the standard include and library directories
+ for your operating system, you should be able to compile the demonstra-
+ tion program using this command:
+
+ gcc -o pcre2demo pcre2demo.c -lpcre2-8
+
+ If PCRE2 is installed elsewhere, you may need to add additional options
+ to the command line. For example, on a Unix-like system that has PCRE2
+ installed in /usr/local, you can compile the demonstration program
+ using a command like this:
+
+ gcc -o pcre2demo -I/usr/local/include pcre2demo.c \
+ -L/usr/local/lib -lpcre2-8
+
+
+ Once you have compiled and linked the demonstration program, you can
+ run simple tests like this:
+
+ ./pcre2demo 'cat|dog' 'the cat sat on the mat'
+ ./pcre2demo -g 'cat|dog' 'the dog sat on the cat'
+
+ Note that there is a much more comprehensive test program, called
+ pcre2test, which supports many more facilities for testing regular
+ expressions using the PCRE2 libraries. The pcre2demo program is pro-
+ vided as a simple coding example.
+
+ If you try to run pcre2demo when PCRE2 is not installed in the standard
+ library directory, you may get an error like this on some operating
+ systems (e.g. Solaris):
+
+ ld.so.1: a.out: fatal: libpcre2.so.0: open failed: No such file or
+ directory
+
+ This is caused by the way shared library support works on those sys-
+ tems. You need to add
+
+ -R/usr/local/lib
+
+ (for example) to the compile command to get round this problem.

+ size is 1088 bytes). For more details of character tables, see the sec-
+ tion on locale support in the pcre2api documentation.
+
+ The function pcre2_serialize_encode() creates a serialized byte stream
+ from a list of compiled patterns. Its first two arguments specify the
+ list, being a pointer to a vector of pointers to compiled patterns, and
+ the length of the vector. The third and fourth arguments point to vari-
+ ables which are set to point to the created byte stream and its length,
+ respectively. The final argument is a pointer to a general context,
+ which can be used to specify custom memory mangagement functions. If
+ this argument is NULL, malloc() is used to obtain memory for the byte
+ stream. The yield of the function is the number of serialized patterns,
+ or one of the following negative error codes:
+
+ PCRE2_ERROR_BADDATA the number of patterns is zero or less
+ PCRE2_ERROR_BADMAGIC mismatch of id bytes in one of the patterns
+ PCRE2_ERROR_MEMORY memory allocation failed
+ PCRE2_ERROR_MIXEDTABLES the patterns do not all use the same tables
+ PCRE2_ERROR_NULL the 1st, 3rd, or 4th argument is NULL
+
+ PCRE2_ERROR_BADMAGIC means either that a pattern's code has been cor-
+ rupted, or that a slot in the vector does not point to a compiled pat-
+ tern.
+
+ Once a set of patterns has been serialized you can save the data in any
+ appropriate manner. Here is sample code that compiles two patterns and
+ writes them to a file. It assumes that the variable fd refers to a file
+ that is open for output. The error checking that should be present in a
+ real application has been omitted for simplicity.
+
+ int errorcode;
+ uint8_t *bytes;
+ PCRE2_SIZE erroroffset;
+ PCRE2_SIZE bytescount;
+ pcre2_code *list_of_codes[2];
+ list_of_codes[0] = pcre2_compile("first pattern",
+ PCRE2_ZERO_TERMINATED, 0, &errorcode, &erroroffset, NULL);
+ list_of_codes[1] = pcre2_compile("second pattern",
+ PCRE2_ZERO_TERMINATED, 0, &errorcode, &erroroffset, NULL);
+ errorcode = pcre2_serialize_encode(list_of_codes, 2, &bytes,
+ &bytescount, NULL);
+ errorcode = fwrite(bytes, 1, bytescount, fd);
+
+ Note that the serialized data is binary data that may contain any of
+ the 256 possible byte values. On systems that make a distinction
+ between binary and non-binary data, be sure that the file is opened for
+ binary output.
+
+ Serializing a set of patterns leaves the original data untouched, so
+ they can still be used for matching. Their memory must eventually be
+ freed in the usual way by calling pcre2_code_free(). When you have fin-
+ ished with the byte stream, it too must be freed by calling pcre2_seri-
+ alize_free().
+
+
+RE-USING PRECOMPILED PATTERNS
+
+ In order to re-use a set of saved patterns you must first make the
+ serialized byte stream available in main memory (for example, by read-
+ ing from a file). The management of this memory block is up to the
+ application. You can use the pcre2_serialize_get_number_of_codes()
+ function to find out how many compiled patterns are in the serialized
+ data without actually decoding the patterns:
+
+ uint8_t *bytes = <serialized data>;
+ int32_t number_of_codes = pcre2_serialize_get_number_of_codes(bytes);
+
+ The pcre2_serialize_decode() function reads a byte stream and recreates
+ the compiled patterns in new memory blocks, setting pointers to them in
+ a vector. The first two arguments are a pointer to a suitable vector
+ and its length, and the third argument points to a byte stream. The
+ final argument is a pointer to a general context, which can be used to
+ specify custom memory mangagement functions for the decoded patterns.
+ If this argument is NULL, malloc() and free() are used. After deserial-
+ ization, the byte stream is no longer needed and can be discarded.
+
+ int32_t number_of_codes;
+ pcre2_code *list_of_codes[2];
+ uint8_t *bytes = <serialized data>;
+ int32_t number_of_codes =
+ pcre2_serialize_decode(list_of_codes, 2, bytes, NULL);
+
+ If the vector is not large enough for all the patterns in the byte
+ stream, it is filled with those that fit, and the remainder are
+ ignored. The yield of the function is the number of decoded patterns,
+ or one of the following negative error codes:
+
+ PCRE2_ERROR_BADDATA second argument is zero or less
+ PCRE2_ERROR_BADMAGIC mismatch of id bytes in the data
+ PCRE2_ERROR_BADMODE mismatch of variable unit size or PCRE2 version
+ PCRE2_ERROR_MEMORY memory allocation failed
+ PCRE2_ERROR_NULL first or third argument is NULL
+
+ PCRE2_ERROR_BADMAGIC may mean that the data is corrupt, or that it was
+ compiled on a system with different endianness.
+
+ Decoded patterns can be used for matching in the usual way, and must be
+ freed by calling pcre2_code_free(). However, be aware that there is a
+ potential race issue if you are using multiple patterns that were
+ decoded from a single byte stream in a multithreaded application. A
+ single copy of the character tables is used by all the decoded patterns
+ and a reference count is used to arrange for its memory to be automati-
+ cally freed when the last pattern is freed, but there is no locking on
+ this reference count. Therefore, if you want to call pcre2_code_free()
+ for these patterns in different threads, you must arrange your own
+ locking, and ensure that pcre2_code_free() cannot be called by two
+ threads at the same time.
+
+ If a pattern was processed by pcre2_jit_compile() before being serial-
+ ized, the JIT data is discarded and so is no longer available after a
+ save/restore cycle. You can, however, process a restored pattern with
+ pcre2_jit_compile() if you wish.

+
+PCRE2 DISCUSSION OF STACK USAGE
+
+ When you call pcre2_match(), it makes use of an internal function
+ called match(). This calls itself recursively at branch points in the
+ pattern, in order to remember the state of the match so that it can
+ back up and try a different alternative after a failure. As matching
+ proceeds deeper and deeper into the tree of possibilities, the recur-
+ sion depth increases. The match() function is also called in other cir-
+ cumstances, for example, whenever a parenthesized sub-pattern is
+ entered, and in certain cases of repetition.
+
+ Not all calls of match() increase the recursion depth; for an item such
+ as a* it may be called several times at the same level, after matching
+ different numbers of a's. Furthermore, in a number of cases where the
+ result of the recursive call would immediately be passed back as the
+ result of the current call (a "tail recursion"), the function is just
+ restarted instead.
+
+ Each time the internal match() function is called recursively, it uses
+ memory from the process stack. For certain kinds of pattern and data,
+ very large amounts of stack may be needed, despite the recognition of
+ "tail recursion". Note that if PCRE2 is compiled with the -fsani-
+ tize=address option of the GCC compiler, the stack requirements are
+ greatly increased.
+
+ The above comments apply when pcre2_match() is run in its normal inter-
+ pretive manner. If the compiled pattern was processed by pcre2_jit_com-
+ pile(), and just-in-time compiling was successful, and the options
+ passed to pcre2_match() were not incompatible, the matching process
+ uses the JIT-compiled code instead of the match() function. In this
+ case, the memory requirements are handled entirely differently. See the
+ pcre2jit documentation for details.
+
+ The pcre2_dfa_match() function operates in a different way to
+ pcre2_match(), and uses recursion only when there is a regular expres-
+ sion recursion or subroutine call in the pattern. This includes the
+ processing of assertion and "once-only" subpatterns, which are handled
+ like subroutine calls. Normally, these are never very deep, and the
+ limit on the complexity of pcre2_dfa_match() is controlled by the
+ amount of workspace it is given. However, it is possible to write pat-
+ terns with runaway infinite recursions; such patterns will cause
+ pcre2_dfa_match() to run out of stack. At present, there is no protec-
+ tion against this.
+
+ The comments that follow do NOT apply to pcre2_dfa_match(); they are
+ relevant only for pcre2_match() without the JIT optimization.
+
+ Reducing pcre2_match()'s stack usage
+
+ You can often reduce the amount of recursion, and therefore the amount
+ of stack used, by modifying the pattern that is being matched. Con-
+ sider, for example, this pattern:
+
+ ([^<]|<(?!inet))+
+
+ It matches from wherever it starts until it encounters "<inet" or the
+ end of the data, and is the kind of pattern that might be used when
+ processing an XML file. Each iteration of the outer parentheses matches
+ either one character that is not "<" or a "<" that is not followed by
+ "inet". However, each time a parenthesis is processed, a recursion
+ occurs, so this formulation uses a stack frame for each matched charac-
+ ter. For a long string, a lot of stack is required. Consider now this
+ rewritten pattern, which matches exactly the same strings:
+
+ ([^<]++|<(?!inet))+
+
+ This uses very much less stack, because runs of characters that do not
+ contain "<" are "swallowed" in one item inside the parentheses. Recur-
+ sion happens only when a "<" character that is not followed by "inet"
+ is encountered (and we assume this is relatively rare). A possessive
+ quantifier is used to stop any backtracking into the runs of non-"<"
+ characters, but that is not related to stack usage.
+
+ This example shows that one way of avoiding stack problems when match-
+ ing long subject strings is to write repeated parenthesized subpatterns
+ to match more than one character whenever possible.
+
+ Compiling PCRE2 to use heap instead of stack for pcre2_match()
+
+ In environments where stack memory is constrained, you might want to
+ compile PCRE2 to use heap memory instead of stack for remembering back-
+ up points when pcre2_match() is running. This makes it run more slowly,
+ however. Details of how to do this are given in the pcre2build documen-
+ tation. When built in this way, instead of using the stack, PCRE2 gets
+ memory for remembering backup points from the heap. By default, the
+ memory is obtained by calling the system malloc() function, but you can
+ arrange to supply your own memory management function. For details, see
+ the section entitled "The match context" in the pcre2api documentation.
+ Since the block sizes are always the same, it may be possible to imple-
+ ment customized a memory handler that is more efficient than the stan-
+ dard function. The memory blocks obtained for this purpose are retained
+ and re-used if possible while pcre2_match() is running. They are all
+ freed just before it exits.
+
+ Limiting pcre2_match()'s stack usage
+
+ You can set limits on the number of times the internal match() function
+ is called, both in total and recursively. If a limit is exceeded,
+ pcre2_match() returns an error code. Setting suitable limits should
+ prevent it from running out of stack. The default values of the limits
+ are very large, and unlikely ever to operate. They can be changed when
+ PCRE2 is built, and they can also be set when pcre2_match() is called.
+ For details of these interfaces, see the pcre2build documentation and
+ the section entitled "The match context" in the pcre2api documentation.
+
+ As a very rough rule of thumb, you should reckon on about 500 bytes per
+ recursion. Thus, if you want to limit your stack usage to 8Mb, you
+ should set the limit at 16000 recursions. A 64Mb stack, on the other
+ hand, can support around 128000 recursions.
+
+ The pcre2test test program has a modifier called "find_limits" which,
+ if applied to a subject line, causes it to find the smallest limits
+ that allow a a pattern to match. This is done by calling pcre2_match()
+ repeatedly with different limits.
+
+ Changing stack size in Unix-like systems
+
+ In Unix-like environments, there is not often a problem with the stack
+ unless very long strings are involved, though the default limit on
+ stack size varies from system to system. Values from 8Mb to 64Mb are
+ common. You can find your default limit by running the command:
+
+ ulimit -s
+
+ Unfortunately, the effect of running out of stack is often SIGSEGV,
+ though sometimes a more explicit error message is given. You can nor-
+ mally increase the limit on stack size by code such as this:
+
+ struct rlimit rlim;
+ getrlimit(RLIMIT_STACK, &rlim);
+ rlim.rlim_cur = 100*1024*1024;
+ setrlimit(RLIMIT_STACK, &rlim);
+
+ This reads the current limits (soft and hard) using getrlimit(), then
+ attempts to increase the soft limit to 100Mb using setrlimit(). You
+ must do this before calling pcre2_match().
+
+ Changing stack size in Mac OS X
+
+ Using setrlimit(), as described above, should also work on Mac OS X. It
+ is also possible to set a stack size when linking a program. There is a
+ discussion about stack sizes in Mac OS X at this web site:
+ http://developer.apple.com/qa/qa2005/qa1419.html.

+
+
+
+NAME
+ PCRE2 - Perl-compatible regular expressions (revised API)
+
+PCRE2 REGULAR EXPRESSION SYNTAX SUMMARY
+
+ The full syntax and semantics of the regular expressions that are sup-
+ ported by PCRE2 are described in the pcre2pattern documentation. This
+ document contains a quick-reference summary of the syntax.
+
+
+QUOTING
+
+ \x where x is non-alphanumeric is a literal x
+ \Q...\E treat enclosed characters as literal
+
+
+ESCAPED CHARACTERS
+
+ This table applies to ASCII and Unicode environments.
+
+ \a alarm, that is, the BEL character (hex 07)
+ \cx "control-x", where x is any ASCII printing character
+ \e escape (hex 1B)
+ \f form feed (hex 0C)
+ \n newline (hex 0A)
+ \r carriage return (hex 0D)
+ \t tab (hex 09)
+ \0dd character with octal code 0dd
+ \ddd character with octal code ddd, or backreference
+ \o{ddd..} character with octal code ddd..
+ \U "U" if PCRE2_ALT_BSUX is set (otherwise is an error)
+ \uhhhh character with hex code hhhh (if PCRE2_ALT_BSUX is set)
+ \xhh character with hex code hh
+ \x{hhh..} character with hex code hhh..
+
+ Note that \0dd is always an octal code. The treatment of backslash fol-
+ lowed by a non-zero digit is complicated; for details see the section
+ "Non-printing characters" in the pcre2pattern documentation, where
+ details of escape processing in EBCDIC environments are also given.
+
+ When \x is not followed by {, from zero to two hexadecimal digits are
+ read, but if PCRE2_ALT_BSUX is set, \x must be followed by two hexadec-
+ imal digits to be recognized as a hexadecimal escape; otherwise it
+ matches a literal "x". Likewise, if \u (in ALT_BSUX mode) is not fol-
+ lowed by four hexadecimal digits, it matches a literal "u".
+
+
+CHARACTER TYPES
+
+ . any character except newline;
+ in dotall mode, any character whatsoever
+ \C one code unit, even in UTF mode (best avoided)
+ \d a decimal digit
+ \D a character that is not a decimal digit
+ \h a horizontal white space character
+ \H a character that is not a horizontal white space character
+ \N a character that is not a newline
+ \p{xx} a character with the xx property
+ \P{xx} a character without the xx property
+ \R a newline sequence
+ \s a white space character
+ \S a character that is not a white space character
+ \v a vertical white space character
+ \V a character that is not a vertical white space character
+ \w a "word" character
+ \W a "non-word" character
+ \X a Unicode extended grapheme cluster
+
+ \C is dangerous because it may leave the current matching point in the
+ middle of a UTF-8 or UTF-16 character. The application can lock out the
+ use of \C by setting the PCRE2_NEVER_BACKSLASH_C option. It is also
+ possible to build PCRE2 with the use of \C permanently disabled.
+
+ By default, \d, \s, and \w match only ASCII characters, even in UTF-8
+ mode or in the 16-bit and 32-bit libraries. However, if locale-specific
+ matching is happening, \s and \w may also match characters with code
+ points in the range 128-255. If the PCRE2_UCP option is set, the behav-
+ iour of these escape sequences is changed to use Unicode properties and
+ they match many more characters.

+ so only if the pattern is not anchored.
+
+ (*COMMIT) overall failure, no advance of starting point
+ (*PRUNE) advance to next starting character
+ (*PRUNE:NAME) equivalent to (*MARK:NAME)(*PRUNE)
+ (*SKIP) advance to current matching position
+ (*SKIP:NAME) advance to position corresponding to an earlier
+ (*MARK:NAME); if not found, the (*SKIP) is ignored
+ (*THEN) local failure, backtrack to next alternation
+ (*THEN:NAME) equivalent to (*MARK:NAME)(*THEN)
+
+
+CALLOUTS
+
+ (?C) callout (assumed number 0)
+ (?Cn) callout with numerical data n
+ (?C"text") callout with string data
+
+ The allowed string delimiters are ` ' " ^ % # $ (which are the same for
+ the start and the end), and the starting delimiter { matched with the
+ ending delimiter }. To encode the ending delimiter within the string,
+ double it.

+PCRE2UNICODE(3) Library Functions Manual PCRE2UNICODE(3)
+
+
+
+NAME
+ PCRE - Perl-compatible regular expressions (revised API)
+
+UNICODE AND UTF SUPPORT
+
+ When PCRE2 is built with Unicode support (which is the default), it has
+ knowledge of Unicode character properties and can process text strings
+ in UTF-8, UTF-16, or UTF-32 format (depending on the code unit width).
+ However, by default, PCRE2 assumes that one code unit is one character.
+ To process a pattern as a UTF string, where a character may require
+ more than one code unit, you must call pcre2_compile() with the
+ PCRE2_UTF option flag, or the pattern must start with the sequence
+ (*UTF). When either of these is the case, both the pattern and any sub-
+ ject strings that are matched against it are treated as UTF strings
+ instead of strings of individual one-code-unit characters.
+
+ If you do not need Unicode support you can build PCRE2 without it, in
+ which case the library will be smaller.
+
+
+UNICODE PROPERTY SUPPORT
+
+ When PCRE2 is built with Unicode support, the escape sequences \p{..},
+ \P{..}, and \X can be used. The Unicode properties that can be tested
+ are limited to the general category properties such as Lu for an upper
+ case letter or Nd for a decimal number, the Unicode script names such
+ as Arabic or Han, and the derived properties Any and L&. Full lists are
+ given in the pcre2pattern and pcre2syntax documentation. Only the short
+ names for properties are supported. For example, \p{L} matches a let-
+ ter. Its Perl synonym, \p{Letter}, is not supported. Furthermore, in
+ Perl, many properties may optionally be prefixed by "Is", for compati-
+ bility with Perl 5.6. PCRE does not support this.
+
+
+WIDE CHARACTERS AND UTF MODES
+
+ Codepoints less than 256 can be specified in patterns by either braced
+ or unbraced hexadecimal escape sequences (for example, \x{b3} or \xb3).
+ Larger values have to use braced sequences. Unbraced octal code points
+ up to \777 are also recognized; larger ones can be coded using \o{...}.
+
+ In UTF modes, repeat quantifiers apply to complete UTF characters, not
+ to individual code units.
+
+ In UTF modes, the dot metacharacter matches one UTF character instead
+ of a single code unit.
+
+ The escape sequence \C can be used to match a single code unit, in a
+ UTF mode, but its use can lead to some strange effects because it
+ breaks up multi-unit characters (see the description of \C in the
+ pcre2pattern documentation). The use of \C is not supported by the
+ alternative matching function pcre2_dfa_match() when in UTF mode. Its
+ use provokes a match-time error. The JIT optimization also does not
+ support \C in UTF mode. If JIT optimization is requested for a UTF
+ pattern that contains \C, it will not succeed, and so the matching will
+ be carried out by the normal interpretive function.
+
+ The character escapes \b, \B, \d, \D, \s, \S, \w, and \W correctly test
+ characters of any code value, but, by default, the characters that
+ PCRE2 recognizes as digits, spaces, or word characters remain the same
+ set as in non-UTF mode, all with code points less than 256. This
+ remains true even when PCRE2 is built to include Unicode support,
+ because to do otherwise would slow down matching in many common cases.
+ Note that this also applies to \b and \B, because they are defined in
+ terms of \w and \W. If you want to test for a wider sense of, say,
+ "digit", you can use explicit Unicode property tests such as \p{Nd}.
+ Alternatively, if you set the PCRE2_UCP option, the way that the char-
+ acter escapes work is changed so that Unicode properties are used to
+ determine which characters match. There are more details in the section
+ on generic character types in the pcre2pattern documentation.
+
+ Similarly, characters that match the POSIX named character classes are
+ all low-valued characters, unless the PCRE2_UCP option is set.
+
+ However, the special horizontal and vertical white space matching
+ escapes (\h, \H, \v, and \V) do match all the appropriate Unicode char-
+ acters, whether or not PCRE2_UCP is set.
+
+ Case-insensitive matching in UTF mode makes use of Unicode properties.
+ A few Unicode characters such as Greek sigma have more than two code-
+ points that are case-equivalent, and these are treated as such.
+
+
+VALIDITY OF UTF STRINGS
+
+ When the PCRE2_UTF option is set, the strings passed as patterns and
+ subjects are (by default) checked for validity on entry to the relevant
+ functions. If an invalid UTF string is passed, an negative error code
+ is returned. The code unit offset to the offending character can be
+ extracted from the match data block by calling pcre2_get_startchar(),
+ which is used for this purpose after a UTF error.
+
+ UTF-16 and UTF-32 strings can indicate their endianness by special code
+ knows as a byte-order mark (BOM). The PCRE2 functions do not handle
+ this, expecting strings to be in host byte order.
+
+ A UTF string is checked before any other processing takes place. In the
+ case of pcre2_match() and pcre2_dfa_match() calls with a non-zero
+ starting offset, the check is applied only to that part of the subject
+ that could be inspected during matching, and there is a check that the
+ starting offset points to the first code unit of a character or to the
+ end of the subject. If there are no lookbehind assertions in the pat-
+ tern, the check starts at the starting offset. Otherwise, it starts at
+ the length of the longest lookbehind before the starting offset, or at
+ the start of the subject if there are not that many characters before
+ the starting offset. Note that the sequences \b and \B are one-charac-
+ ter lookbehinds.
+
+ In addition to checking the format of the string, there is a check to
+ ensure that all code points lie in the range U+0 to U+10FFFF, excluding
+ the surrogate area. The so-called "non-character" code points are not
+ excluded because Unicode corrigendum #9 makes it clear that they should
+ not be.
+
+ Characters in the "Surrogate Area" of Unicode are reserved for use by
+ UTF-16, where they are used in pairs to encode code points with values
+ greater than 0xFFFF. The code points that are encoded by UTF-16 pairs
+ are available independently in the UTF-8 and UTF-32 encodings. (In
+ other words, the whole surrogate thing is a fudge for UTF-16 which
+ unfortunately messes up UTF-8 and UTF-32.)
+
+ In some situations, you may already know that your strings are valid,
+ and therefore want to skip these checks in order to improve perfor-
+ mance, for example in the case of a long subject string that is being
+ scanned repeatedly. If you set the PCRE2_NO_UTF_CHECK option at com-
+ pile time or at match time, PCRE2 assumes that the pattern or subject
+ it is given (respectively) contains only valid UTF code unit sequences.
+
+ Passing PCRE2_NO_UTF_CHECK to pcre2_compile() just disables the check
+ for the pattern; it does not also apply to subject strings. If you want
+ to disable the check for a subject string you must pass this option to
+ pcre2_match() or pcre2_dfa_match().
+
+ If you pass an invalid UTF string when PCRE2_NO_UTF_CHECK is set, the
+ result is undefined and your program may crash or loop indefinitely.
+
+ Errors in UTF-8 strings
+
+ The following negative error codes are given for invalid UTF-8 strings:
+
+ PCRE2_ERROR_UTF8_ERR1
+ PCRE2_ERROR_UTF8_ERR2
+ PCRE2_ERROR_UTF8_ERR3
+ PCRE2_ERROR_UTF8_ERR4
+ PCRE2_ERROR_UTF8_ERR5
+
+ The string ends with a truncated UTF-8 character; the code specifies
+ how many bytes are missing (1 to 5). Although RFC 3629 restricts UTF-8
+ characters to be no longer than 4 bytes, the encoding scheme (origi-
+ nally defined by RFC 2279) allows for up to 6 bytes, and this is
+ checked first; hence the possibility of 4 or 5 missing bytes.
+
+ PCRE2_ERROR_UTF8_ERR6
+ PCRE2_ERROR_UTF8_ERR7
+ PCRE2_ERROR_UTF8_ERR8
+ PCRE2_ERROR_UTF8_ERR9
+ PCRE2_ERROR_UTF8_ERR10
+
+ The two most significant bits of the 2nd, 3rd, 4th, 5th, or 6th byte of
+ the character do not have the binary value 0b10 (that is, either the
+ most significant bit is 0, or the next bit is 1).
+
+ PCRE2_ERROR_UTF8_ERR11
+ PCRE2_ERROR_UTF8_ERR12
+
+ A character that is valid by the RFC 2279 rules is either 5 or 6 bytes
+ long; these code points are excluded by RFC 3629.
+
+ PCRE2_ERROR_UTF8_ERR13
+
+ A 4-byte character has a value greater than 0x10fff; these code points
+ are excluded by RFC 3629.
+
+ PCRE2_ERROR_UTF8_ERR14
+
+ A 3-byte character has a value in the range 0xd800 to 0xdfff; this
+ range of code points are reserved by RFC 3629 for use with UTF-16, and
+ so are excluded from UTF-8.
+
+ PCRE2_ERROR_UTF8_ERR15
+ PCRE2_ERROR_UTF8_ERR16
+ PCRE2_ERROR_UTF8_ERR17
+ PCRE2_ERROR_UTF8_ERR18
+ PCRE2_ERROR_UTF8_ERR19
+
+ A 2-, 3-, 4-, 5-, or 6-byte character is "overlong", that is, it codes
+ for a value that can be represented by fewer bytes, which is invalid.
+ For example, the two bytes 0xc0, 0xae give the value 0x2e, whose cor-
+ rect coding uses just one byte.
+
+ PCRE2_ERROR_UTF8_ERR20
+
+ The two most significant bits of the first byte of a character have the
+ binary value 0b10 (that is, the most significant bit is 1 and the sec-
+ ond is 0). Such a byte can only validly occur as the second or subse-
+ quent byte of a multi-byte character.
+
+ PCRE2_ERROR_UTF8_ERR21
+
+ The first byte of a character has the value 0xfe or 0xff. These values
+ can never occur in a valid UTF-8 string.
+
+ Errors in UTF-16 strings
+
+ The following negative error codes are given for invalid UTF-16
+ strings:
+
+ PCRE_UTF16_ERR1 Missing low surrogate at end of string
+ PCRE_UTF16_ERR2 Invalid low surrogate follows high surrogate
+ PCRE_UTF16_ERR3 Isolated low surrogate
+
+
+ Errors in UTF-32 strings
+
+ The following negative error codes are given for invalid UTF-32
+ strings:
+
+ PCRE_UTF32_ERR1 Surrogate character (range from 0xd800 to 0xdfff)
+ PCRE_UTF32_ERR2 Code point is greater than 0x10ffff

+.rs
+.sp
+This function makes it possible for a client program to find out which optional
+features are available in the version of the PCRE2 library it is using. The
+arguments are as follows:
+.sp
+ \fIwhat\fP A code specifying what information is required
+ \fIwhere\fP Points to where to put the information
+.sp
+If \fIwhere\fP is NULL, the function returns the amount of memory needed for
+the requested information. When the information is a string, the value is in
+code units; for other types of data it is in bytes.
+.P
+If \fBwhere\fP is not NULL, for PCRE2_CONFIG_JITTARGET,
+PCRE2_CONFIG_UNICODE_VERSION, and PCRE2_CONFIG_VERSION it must point to a
+buffer that is large enough to hold the string. For all other codes it must
+point to a uint32_t integer variable. The available codes are:
+.sp
+ PCRE2_CONFIG_BSR Indicates what \eR matches by default:
+ PCRE2_BSR_UNICODE
+ PCRE2_BSR_ANYCRLF
+ PCRE2_CONFIG_JIT Availability of just-in-time compiler
+ support (1=yes 0=no)
+ PCRE2_CONFIG_JITTARGET Information about the target archi-
+ tecture for the JIT compiler
+ PCRE2_CONFIG_LINKSIZE Configured internal link size (2, 3, 4)
+ PCRE2_CONFIG_MATCHLIMIT Default internal resource limit
+ PCRE2_CONFIG_NEWLINE Code for the default newline sequence:
+ PCRE2_NEWLINE_CR
+ PCRE2_NEWLINE_LF
+ PCRE2_NEWLINE_CRLF
+ PCRE2_NEWLINE_ANY
+ PCRE2_NEWLINE_ANYCRLF
+ PCRE2_CONFIG_PARENSLIMIT Default parentheses nesting limit
+ PCRE2_CONFIG_RECURSIONLIMIT Internal recursion depth limit
+ PCRE2_CONFIG_STACKRECURSE Recursion implementation (1=stack
+ 0=heap)
+ PCRE2_CONFIG_UNICODE Availability of Unicode support (1=yes
+ 0=no)
+ PCRE2_CONFIG_UNICODE_VERSION The Unicode version (a string)
+ PCRE2_CONFIG_VERSION The PCRE2 version (a string)
+.sp
+The function yields a non-negative value on success or the negative value
+PCRE2_ERROR_BADOPTION otherwise. This is also the result for the
+PCRE2_CONFIG_JITTARGET code if JIT support is not available. When a string is
+requested, the function returns the number of code units used, including the
+terminating zero.

+.PP
+.nf
+.B int pcre2_dfa_match(const pcre2_code *\fIcode\fP, PCRE2_SPTR \fIsubject\fP,

+.fi
+.
+.SH DESCRIPTION
+.rs
+.sp
+This function matches a compiled regular expression against a given subject
+string, using an alternative matching algorithm that scans the subject string
+just once (\fInot\fP Perl-compatible). (The Perl-compatible matching function
+is \fBpcre2_match()\fP.) The arguments for this function are:
+.sp
+ \fIcode\fP Points to the compiled pattern
+ \fIsubject\fP Points to the subject string
+ \fIlength\fP Length of the subject string
+ \fIstartoffset\fP Offset in the subject at which to start matching
+ \fIoptions\fP Option bits
+ \fImatch_data\fP Points to a match data block, for results
+ \fImcontext\fP Points to a match context, or is NULL
+ \fIworkspace\fP Points to a vector of ints used as working space
+ \fIwscount\fP Number of elements in the vector
+.sp
+For \fBpcre2_dfa_match()\fP, a match context is needed only if you want to set
+up a callout function. The \fIlength\fP and \fIstartoffset\fP values are code
+units, not characters. The options are:
+.sp
+ PCRE2_ANCHORED Match only at the first position
+ PCRE2_NOTBOL Subject is not the beginning of a line
+ PCRE2_NOTEOL Subject is not the end of a line
+ PCRE2_NOTEMPTY An empty string is not a valid match
+ PCRE2_NOTEMPTY_ATSTART An empty string at the start of the subject
+ is not a valid match
+ PCRE2_NO_UTF_CHECK Do not check the subject for UTF
+ validity (only relevant if PCRE2_UTF
+ was set at compile time)
+ PCRE2_PARTIAL_SOFT Return PCRE2_ERROR_PARTIAL for a partial
+ match if no full matches are found
+ PCRE2_PARTIAL_HARD Return PCRE2_ERROR_PARTIAL for a partial match
+ even if there is a full match as well
+ PCRE2_DFA_RESTART Restart after a partial match
+ PCRE2_DFA_SHORTEST Return only the shortest match
+.sp
+There are restrictions on what may appear in a pattern when using this matching
+function. Details are given in the

+that has been successfully processed by the JIT compiler. The information that

+ callback_data a JIT stack or a value to be passed to the callback
+.P
+If \fIcallback\fP is NULL and \fIcallback_data\fP is NULL, an internal 32K
+block on the machine stack is used.
+.P
+If \fIcallback\fP is NULL and \fIcallback_data\fP is not NULL,
+\fIcallback_data\fP must be a valid JIT stack, the result of calling
+\fBpcre2_jit_stack_create()\fP.

+If \fIcallback\fP not NULL, it is called with \fIcallback_data\fP as an

+result is NULL, the internal 32K stack is used; otherwise the return value must
+be a valid JIT stack, the result of calling \fBpcre2_jit_stack_create()\fP.
+.P
+You may safely use the same JIT stack for multiple patterns, as long as they
+are all matched in the same thread. In a multithread application, each thread

+.
+.SH DESCRIPTION
+.rs
+.sp
+This function matches a compiled regular expression against a given subject
+string, using a matching algorithm that is similar to Perl's. It returns
+offsets to captured substrings. Its arguments are:
+.sp
+ \fIcode\fP Points to the compiled pattern
+ \fIsubject\fP Points to the subject string
+ \fIlength\fP Length of the subject string
+ \fIstartoffset\fP Offset in the subject at which to start matching
+ \fIoptions\fP Option bits
+ \fImatch_data\fP Points to a match data block, for results
+ \fImcontext\fP Points to a match context, or is NULL
+.sp
+A match context is needed only if you want to:
+.sp
+ Set up a callout function
+ Change the limit for calling the internal function \fImatch()\fP
+ Change the limit for calling \fImatch()\fP recursively
+ Set custom memory management when the heap is used for recursion
+.sp
+The \fIlength\fP and \fIstartoffset\fP values are code
+units, not characters. The options are:
+.sp
+ PCRE2_ANCHORED Match only at the first position
+ PCRE2_NOTBOL Subject string is not the beginning of a line
+ PCRE2_NOTEOL Subject string is not the end of a line
+ PCRE2_NOTEMPTY An empty string is not a valid match
+ PCRE2_NOTEMPTY_ATSTART An empty string at the start of the subject
+ is not a valid match
+ PCRE2_NO_UTF_CHECK Do not check the subject for UTF
+ validity (only relevant if PCRE2_UTF
+ was set at compile time)
+ PCRE2_PARTIAL_SOFT Return PCRE2_ERROR_PARTIAL for a partial
+ match if no full matches are found
+ PCRE2_PARTIAL_HARD Return PCRE2_ERROR_PARTIAL for a partial match
+ if that is found before a full match

+.SH DESCRIPTION
+.rs
+.sp
+This function matches a compiled regular expression against a given subject
+string, using a matching algorithm that is similar to Perl's. It then makes a
+copy of the subject, substituting a replacement string for what was matched.
+Its arguments are:
+.sp
+ \fIcode\fP Points to the compiled pattern
+ \fIsubject\fP Points to the subject string
+ \fIlength\fP Length of the subject string
+ \fIstartoffset\fP Offset in the subject at which to start matching
+ \fIoptions\fP Option bits
+ \fImatch_data\fP Points to a match data block, or is NULL
+ \fImcontext\fP Points to a match context, or is NULL
+ \fIreplacement\fP Points to the replacement string
+ \fIrlength\fP Length of the replacement string
+ \fIoutputbuffer\fP Points to the output buffer
+ \fIoutlengthptr\fP Points to the length of the output buffer
+.sp
+A match context is needed only if you want to:
+.sp
+ Set up a callout function
+ Change the limit for calling the internal function \fImatch()\fP
+ Change the limit for calling \fImatch()\fP recursively
+ Set custom memory management when the heap is used for recursion
+.sp
+The \fIlength\fP, \fIstartoffset\fP and \fIrlength\fP values are code
+units, not characters, as is the contents of the variable pointed at by
+\fIoutlengthptr\fP, which is updated to the actual length of the new string.
+The options are:
+.sp
+ PCRE2_ANCHORED Match only at the first position
+ PCRE2_NOTBOL Subject is not the beginning of a line
+ PCRE2_NOTEOL Subject is not the end of a line
+ PCRE2_NOTEMPTY An empty string is not a valid match
+ PCRE2_NOTEMPTY_ATSTART An empty string at the start of the
+ subject is not a valid match
+ PCRE2_NO_UTF_CHECK Do not check the subject or replacement
+ for UTF validity (only relevant if
+ PCRE2_UTF was set at compile time)
+ PCRE2_SUBSTITUTE_EXTENDED Do extended replacement processing
+ PCRE2_SUBSTITUTE_GLOBAL Replace all occurrences in the subject
+ PCRE2_SUBSTITUTE_OVERFLOW_LENGTH If overflow, compute needed length
+ PCRE2_SUBSTITUTE_UNKNOWN_UNSET Treat unknown group as unset
+ PCRE2_SUBSTITUTE_UNSET_EMPTY Simple unset insert = empty string
+.sp
+The function returns the number of substitutions, which may be zero if there
+were no matches. The result can be greater than one only when
+PCRE2_SUBSTITUTE_GLOBAL is set. In the event of an error, a negative error code
+is returned.

+.SH DESCRIPTION
+.rs
+.sp
+This is a convenience function for extracting all the captured substrings after
+a pattern match. It builds a list of pointers to the strings, and (optionally)
+a second list that contains their lengths (in code units), excluding a
+terminating zero that is added to each of them. All this is done in a single
+block of memory that is obtained using the same memory allocation function that
+was used to get the match data block. The convenience function
+\fBpcre2_substring_list_free()\fP can be used to free it when it is no longer
+needed. The arguments are:
+.sp
+ \fImatch_data\fP The match data block
+ \fIlistptr\fP Where to put a pointer to the list
+ \fIlengthsptr\fP Where to put a pointer to the lengths, or NULL
+.sp
+A pointer to a list of pointers is put in the variable whose address is in
+\fIlistptr\fP. The list is terminated by a NULL pointer. If \fIlengthsptr\fP is
+not NULL, a matching list of lengths is created, and its address is placed in
+\fIlengthsptr\fP. The yield of the function is zero on success or
+PCRE2_ERROR_NOMEMORY if sufficient memory could not be obtained.

+.SH "PCRE2 8-BIT, 16-BIT, AND 32-BIT LIBRARIES"
+.rs
+.sp
+There are three PCRE2 libraries, supporting 8-bit, 16-bit, and 32-bit code
+units, respectively. However, there is just one header file, \fBpcre2.h\fP.
+This contains the function prototypes and other definitions for all three
+libraries. One, two, or all three can be installed simultaneously. On Unix-like
+systems the libraries are called \fBlibpcre2-8\fP, \fBlibpcre2-16\fP, and
+\fBlibpcre2-32\fP, and they can also co-exist with the original PCRE libraries.
+.P
+Character strings are passed to and from a PCRE2 library as a sequence of
+unsigned integers in code units of the appropriate width. Every PCRE2 function
+comes in three different forms, one for each library, for example:
+.sp
+ \fBpcre2_compile_8()\fP
+ \fBpcre2_compile_16()\fP
+ \fBpcre2_compile_32()\fP
+.sp
+There are also three different sets of data types:
+.sp
+ \fBPCRE2_UCHAR8, PCRE2_UCHAR16, PCRE2_UCHAR32\fP
+ \fBPCRE2_SPTR8, PCRE2_SPTR16, PCRE2_SPTR32\fP
+.sp
+The UCHAR types define unsigned code units of the appropriate widths. For
+example, PCRE2_UCHAR16 is usually defined as `uint16_t'. The SPTR types are
+constant pointers to the equivalent UCHAR types, that is, they are pointers to
+vectors of unsigned code units.
+.P
+Many applications use only one code unit width. For their convenience, macros
+are defined whose names are the generic forms such as \fBpcre2_compile()\fP and
+PCRE2_SPTR. These macros use the value of the macro PCRE2_CODE_UNIT_WIDTH to
+generate the appropriate width-specific function and macro names.
+PCRE2_CODE_UNIT_WIDTH is not defined by default. An application must define it
+to be 8, 16, or 32 before including \fBpcre2.h\fP in order to make use of the
+generic names.
+.P
+Applications that use more than one code unit width can be linked with more
+than one PCRE2 library, but must define PCRE2_CODE_UNIT_WIDTH to be 0 before
+including \fBpcre2.h\fP, and then use the real function names. Any code that is
+to be included in an environment where the value of PCRE2_CODE_UNIT_WIDTH is
+unknown should also use the real function names. (Unfortunately, it is not
+possible in C code to save and restore the value of a macro.)
+.P
+If PCRE2_CODE_UNIT_WIDTH is not defined before including \fBpcre2.h\fP, a
+compiler error occurs.
+.P
+When using multiple libraries in an application, you must take care when
+processing any particular pattern to use only functions from a single library.
+For example, if you want to run a match using a pattern that was compiled with
+\fBpcre2_compile_16()\fP, you must do so with \fBpcre2_match_16()\fP, not
+\fBpcre2_match_8()\fP.
+.P
+In the function summaries above, and in the rest of this document and other
+PCRE2 documents, functions and data types are described using their generic
+names, without the 8, 16, or 32 suffix.
+.
+.
+.SH "PCRE2 API OVERVIEW"
+.rs
+.sp
+PCRE2 has its own native API, which is described in this document. There are
+also some wrapper functions for the 8-bit library that correspond to the
+POSIX regular expression API, but they do not give access to all the
+functionality. They are described in the
+.\" HREF
+\fBpcre2posix\fP
+.\"
+documentation. Both these APIs define a set of C function calls.
+.P
+The native API C data types, function prototypes, option values, and error
+codes are defined in the header file \fBpcre2.h\fP, which contains definitions
+of PCRE2_MAJOR and PCRE2_MINOR, the major and minor release numbers for the
+library. Applications can use these to include support for different releases
+of PCRE2.
+.P
+In a Windows environment, if you want to statically link an application program
+against a non-dll PCRE2 library, you must define PCRE2_STATIC before including
+\fBpcre2.h\fP.
+.P
+The functions \fBpcre2_compile()\fP, and \fBpcre2_match()\fP are used for
+compiling and matching regular expressions in a Perl-compatible manner. A
+sample program that demonstrates the simplest way of using them is provided in
+the file called \fIpcre2demo.c\fP in the PCRE2 source distribution. A listing
+of this program is given in the
+.\" HREF
+\fBpcre2demo\fP
+.\"
+documentation, and the
+.\" HREF
+\fBpcre2sample\fP
+.\"
+documentation describes how to compile and run it.
+.P
+Just-in-time compiler support is an optional feature of PCRE2 that can be built
+in appropriate hardware environments. It greatly speeds up the matching
+performance of many patterns. Programs can request that it be used if
+available, by calling \fBpcre2_jit_compile()\fP after a pattern has been
+successfully compiled by \fBpcre2_compile()\fP. This does nothing if JIT
+support is not available.
+.P
+More complicated programs might need to make use of the specialist functions
+\fBpcre2_jit_stack_create()\fP, \fBpcre2_jit_stack_free()\fP, and
+\fBpcre2_jit_stack_assign()\fP in order to control the JIT code's memory usage.
+.P
+JIT matching is automatically used by \fBpcre2_match()\fP if it is available.
+There is also a direct interface for JIT matching, which gives improved
+performance. The JIT-specific functions are discussed in the
+.\" HREF
+\fBpcre2jit\fP
+.\"
+documentation.
+.P
+A second matching function, \fBpcre2_dfa_match()\fP, which is not
+Perl-compatible, is also provided. This uses a different algorithm for the
+matching. The alternative algorithm finds all possible matches (at a given
+point in the subject), and scans the subject just once (unless there are
+lookbehind assertions). However, this algorithm does not return captured
+substrings. A description of the two matching algorithms and their advantages
+and disadvantages is given in the
+.\" HREF
+\fBpcre2matching\fP
+.\"
+documentation. There is no JIT support for \fBpcre2_dfa_match()\fP.
+.P
+In addition to the main compiling and matching functions, there are convenience
+functions for extracting captured substrings from a subject string that has
+been matched by \fBpcre2_match()\fP. They are:
+.sp
+ \fBpcre2_substring_copy_byname()\fP
+ \fBpcre2_substring_copy_bynumber()\fP
+ \fBpcre2_substring_get_byname()\fP
+ \fBpcre2_substring_get_bynumber()\fP
+ \fBpcre2_substring_list_get()\fP
+ \fBpcre2_substring_length_byname()\fP
+ \fBpcre2_substring_length_bynumber()\fP
+ \fBpcre2_substring_nametable_scan()\fP
+ \fBpcre2_substring_number_from_name()\fP
+.sp
+\fBpcre2_substring_free()\fP and \fBpcre2_substring_list_free()\fP are also
+provided, to free the memory used for extracted strings.
+.P
+The function \fBpcre2_substitute()\fP can be called to match a pattern and
+return a copy of the subject string with substitutions for parts that were
+matched.
+.P
+Finally, there are functions for finding out information about a compiled
+pattern (\fBpcre2_pattern_info()\fP) and about the configuration with which
+PCRE2 was built (\fBpcre2_config()\fP).
+.
+.
+.SH "STRING LENGTHS AND OFFSETS"
+.rs
+.sp
+The PCRE2 API uses string lengths and offsets into strings of code units in
+several places. These values are always of type PCRE2_SIZE, which is an
+unsigned integer type, currently always defined as \fIsize_t\fP. The largest
+value that can be stored in such a type (that is ~(PCRE2_SIZE)0) is reserved
+as a special indicator for zero-terminated strings and unset offsets.
+Therefore, the longest string that can be handled is one less than this
+maximum.
+.
+.
+.\" HTML <a name="newlines"></a>
+.SH NEWLINES
+.rs
+.sp
+PCRE2 supports five different conventions for indicating line breaks in
+strings: a single CR (carriage return) character, a single LF (linefeed)
+character, the two-character sequence CRLF, any of the three preceding, or any
+Unicode newline sequence. The Unicode newline sequences are the three just
+mentioned, plus the single characters VT (vertical tab, U+000B), FF (form feed,
+U+000C), NEL (next line, U+0085), LS (line separator, U+2028), and PS
+(paragraph separator, U+2029).
+.P
+Each of the first three conventions is used by at least one operating system as
+its standard newline sequence. When PCRE2 is built, a default can be specified.
+The default default is LF, which is the Unix standard. However, the newline
+convention can be changed by an application when calling \fBpcre2_compile()\fP,
+or it can be specified by special text at the start of the pattern itself; this
+overrides any other settings. See the
+.\" HREF
+\fBpcre2pattern\fP
+.\"
+page for details of the special character sequences.
+.P
+In the PCRE2 documentation the word "newline" is used to mean "the character or
+pair of characters that indicate a line break". The choice of newline
+convention affects the handling of the dot, circumflex, and dollar
+metacharacters, the handling of #-comments in /x mode, and, when CRLF is a
+recognized line ending sequence, the match position advancement for a
+non-anchored pattern. There is more detail about this in the
+.\" HTML <a href="#matchoptions">
+.\" </a>
+section on \fBpcre2_match()\fP options
+.\"
+below.
+.P
+The choice of newline convention does not affect the interpretation of
+the \en or \er escape sequences, nor does it affect what \eR matches; this has
+its own separate convention.
+.
+.
+.SH MULTITHREADING
+.rs
+.sp
+In a multithreaded application it is important to keep thread-specific data
+separate from data that can be shared between threads. The PCRE2 library code
+itself is thread-safe: it contains no static or global variables. The API is
+designed to be fairly simple for non-threaded applications while at the same
+time ensuring that multithreaded applications can use it.
+.P
+There are several different blocks of data that are used to pass information
+between the application and the PCRE2 libraries.
+.P
+(1) A pointer to the compiled form of a pattern is returned to the user when
+\fBpcre2_compile()\fP is successful. The data in the compiled pattern is fixed,
+and does not change when the pattern is matched. Therefore, it is thread-safe,
+that is, the same compiled pattern can be used by more than one thread
+simultaneously. An application can compile all its patterns at the start,
+before forking off multiple threads that use them. However, if the just-in-time
+optimization feature is being used, it needs separate memory stack areas for
+each thread. See the
+.\" HREF
+\fBpcre2jit\fP
+.\"
+documentation for more details.
+.P
+(2) The next section below introduces the idea of "contexts" in which PCRE2
+functions are called. A context is nothing more than a collection of parameters
+that control the way PCRE2 operates. Grouping a number of parameters together
+in a context is a convenient way of passing them to a PCRE2 function without
+using lots of arguments. The parameters that are stored in contexts are in some
+sense "advanced features" of the API. Many straightforward applications will
+not need to use contexts.
+.P
+In a multithreaded application, if the parameters in a context are values that
+are never changed, the same context can be used by all the threads. However, if
+any thread needs to change any value in a context, it must make its own
+thread-specific copy.
+.P
+(3) The matching functions need a block of memory for working space and for
+storing the results of a match. This includes details of what was matched, as
+well as additional information such as the name of a (*MARK) setting. Each
+thread must provide its own version of this memory.
+.
+.
+.SH "PCRE2 CONTEXTS"
+.rs
+.sp
+Some PCRE2 functions have a lot of parameters, many of which are used only by
+specialist applications, for example, those that use custom memory management
+or non-standard character tables. To keep function argument lists at a
+reasonable size, and at the same time to keep the API extensible, "uncommon"
+parameters are passed to certain functions in a \fBcontext\fP instead of
+directly. A context is just a block of memory that holds the parameter values.
+Applications that do not need to adjust any of the context parameters can pass
+NULL when a context pointer is required.
+.P
+There are three different types of context: a general context that is relevant
+for several PCRE2 operations, a compile-time context, and a match-time context.
+.
+.
+.SS "The general context"
+.rs
+.sp
+At present, this context just contains pointers to (and data for) external
+memory management functions that are called from several places in the PCRE2
+library. The context is named `general' rather than specifically `memory'
+because in future other fields may be added. If you do not want to supply your
+own custom memory management functions, you do not need to bother with a
+general context. A general context is created by:
+.sp
+.nf
+.B pcre2_general_context *pcre2_general_context_create(
+.B " void *(*\fIprivate_malloc\fP)(PCRE2_SIZE, void *),"
+.B " void (*\fIprivate_free\fP)(void *, void *), void *\fImemory_data\fP);"
+.fi
+.sp
+The two function pointers specify custom memory management functions, whose
+prototypes are:
+.sp
+ \fBvoid *private_malloc(PCRE2_SIZE, void *);\fP
+ \fBvoid private_free(void *, void *);\fP
+.sp
+Whenever code in PCRE2 calls these functions, the final argument is the value
+of \fImemory_data\fP. Either of the first two arguments of the creation
+function may be NULL, in which case the system memory management functions
+\fImalloc()\fP and \fIfree()\fP are used. (This is not currently useful, as
+there are no other fields in a general context, but in future there might be.)
+The \fIprivate_malloc()\fP function is used (if supplied) to obtain memory for
+storing the context, and all three values are saved as part of the context.
+.P
+Whenever PCRE2 creates a data block of any kind, the block contains a pointer
+to the \fIfree()\fP function that matches the \fImalloc()\fP function that was
+used. When the time comes to free the block, this function is called.
+.P
+A general context can be copied by calling:
+.sp
+.nf
+.B pcre2_general_context *pcre2_general_context_copy(
+.B " pcre2_general_context *\fIgcontext\fP);"
+.fi
+.sp
+The memory used for a general context should be freed by calling:
+.sp
+.nf
+.B void pcre2_general_context_free(pcre2_general_context *\fIgcontext\fP);
+.fi
+.sp
+.
+.

+ The newline character sequence
+ The compile time nested parentheses limit
+ The maximum length of the pattern string

+.sp
+A compile context is also required if you are using custom memory management.

+ending sequence. The value is used by the JIT compiler and by the two
+interpreted matching functions, \fIpcre2_match()\fP and
+\fIpcre2_dfa_match()\fP.
+.sp
+.nf
+.B int pcre2_set_character_tables(pcre2_compile_context *\fIccontext\fP,

+.sp
+.nf
+.B int pcre2_set_max_pattern_length(pcre2_compile_context *\fIccontext\fP,
+.B " PCRE2_SIZE \fIvalue\fP);"
+.fi
+.sp
+This sets a maximum length, in code units, for the pattern string that is to be
+compiled. If the pattern is longer, an error is generated. This facility is
+provided so that applications that accept patterns from external sources can
+limit their size. The default is the largest number that a PCRE2_SIZE variable
+can hold, which is effectively unlimited.
+.sp
+.nf
+.B int pcre2_set_newline(pcre2_compile_context *\fIccontext\fP,
+.B " uint32_t \fIvalue\fP);"
+.fi
+.sp

+PCRE2_NEWLINE_LF (linefeed only), PCRE2_NEWLINE_CRLF (the two-character
+sequence CR followed by LF), PCRE2_NEWLINE_ANYCRLF (any of the above), or
+PCRE2_NEWLINE_ANY (any Unicode newline sequence).
+.P
+When a pattern is compiled with the PCRE2_EXTENDED option, the value of this
+parameter affects the recognition of white space and the end of internal
+comments starting with #. The value is saved with the compiled pattern for
+subsequent use by the JIT compiler and by the two interpreted matching
+functions, \fIpcre2_match()\fP and \fIpcre2_dfa_match()\fP.
+.sp
+.nf
+.B int pcre2_set_parens_nest_limit(pcre2_compile_context *\fIccontext\fP,

+.B int pcre2_set_compile_recursion_guard(pcre2_compile_context *\fIccontext\fP,
+.B " int (*\fIguard_function\fP)(uint32_t, void *), void *\fIuser_data\fP);"
+.fi
+.sp
+There is at least one application that runs PCRE2 in threads with very limited
+system stack, where running out of stack is to be avoided at all costs. The
+parenthesis limit above cannot take account of how much stack is actually
+available. For a finer control, you can supply a function that is called
+whenever \fBpcre2_compile()\fP starts to compile a parenthesized part of a
+pattern. This function can check the actual stack size (or anything else that
+it wants to, of course).
+.P
+The first argument to the callout function gives the current depth of
+nesting, and the second is user data that is set up by the last argument of
+\fBpcre2_set_compile_recursion_guard()\fP. The callout function should return

+\fBpcre2_match()\fP and \fBpcre2_dfa_match()\fP functions return
+PCRE2_ERROR_NOMATCH if a match with a starting point before or at the given
+offset is not found. For example, if the pattern /abc/ is matched against
+"123abc" with an offset limit less than 3, the result is PCRE2_ERROR_NO_MATCH.
+A match can never be found if the \fIstartoffset\fP argument of
+\fBpcre2_match()\fP or \fBpcre2_dfa_match()\fP is greater than the offset
+limit.
+.P
+When using this facility, you must set PCRE2_USE_OFFSET_LIMIT when calling
+\fBpcre2_compile()\fP so that when JIT is in use, different code can be
+compiled. If a match is started with a non-default match limit when
+PCRE2_USE_OFFSET_LIMIT is not set, an error is generated.
+.P
+The offset limit facility can be used to track progress when searching large
+subject strings. See also the PCRE2_FIRSTLINE option, which requires a match to
+start within the first line of the subject. If this is set with an offset
+limit, a match must occur in the first line and also within the offset limit.

+.sp

+.fi
+.sp
+The \fImatch_limit\fP parameter provides a means of preventing PCRE2 from using
+up too many resources when processing patterns that are not going to match, but
+which have a very large number of possibilities in their search trees. The
+classic example is a pattern that uses nested unlimited repeats.
+.P
+Internally, \fBpcre2_match()\fP uses a function called \fBmatch()\fP, which it
+calls repeatedly (sometimes recursively). The limit set by \fImatch_limit\fP is
+imposed on the number of times this function is called during a match, which
+has the effect of limiting the amount of backtracking that can take place. For
+patterns that are not anchored, the count restarts from zero for each position
+in the subject string. This limit is not relevant to \fBpcre2_dfa_match()\fP,
+which ignores it.
+.P
+When \fBpcre2_match()\fP is called with a pattern that was successfully
+processed by \fBpcre2_jit_compile()\fP, the way in which matching is executed
+is entirely different. However, there is still the possibility of runaway
+matching that goes on for a very long time, and so the \fImatch_limit\fP value
+is also used in this case (but in a different way) to limit how long the
+matching can continue.
+.P
+The default value for the limit can be set when PCRE2 is built; the default
+default is 10 million, which handles all but the most extreme cases. If the
+limit is exceeded, \fBpcre2_match()\fP returns PCRE2_ERROR_MATCHLIMIT. A value
+for the match limit may also be supplied by an item at the start of a pattern
+of the form
+.sp
+ (*LIMIT_MATCH=ddd)

+.fi
+.sp
+The \fIrecursion_limit\fP parameter is similar to \fImatch_limit\fP, but
+instead of limiting the total number of times that \fBmatch()\fP is called, it
+limits the depth of recursion. The recursion depth is a smaller number than the
+total number of calls, because not all calls to \fBmatch()\fP are recursive.
+This limit is of use only if it is set smaller than \fImatch_limit\fP.
+.P
+Limiting the recursion depth limits the amount of system stack that can be
+used, or, when PCRE2 has been compiled to use memory on the heap instead of the
+stack, the amount of heap memory that can be used. This limit is not relevant,
+and is ignored, when matching is done using JIT compiled code or by the
+\fBpcre2_dfa_match()\fP function.

+to the general custom memory functions are provided so that special-purpose
+external code can be used for this case, because the memory blocks are all the
+same size. The blocks are retained by \fBpcre2_match()\fP until it is about to

+of these functions, the normal custom memory management functions are used, if

+.\" HREF

+documentation has more details about these optional features.
+.P
+The first argument for \fBpcre2_config()\fP specifies which information is
+required. The second argument is a pointer to memory into which the information
+is placed. If NULL is passed, the function returns the amount of memory that is
+needed for the requested information. For calls that return numerical values,
+the value is in bytes; when requesting these values, \fIwhere\fP should point
+to appropriately aligned memory. For calls that return strings, the required
+length is given in code units, not counting the terminating zero.
+.P
+When requesting information, the returned value from \fBpcre2_config()\fP is
+non-negative on success, or the negative error code PCRE2_ERROR_BADOPTION if
+the value in the first argument is not recognized. The following information is
+available:
+.sp
+ PCRE2_CONFIG_BSR
+.sp
+The output is a uint32_t integer whose value indicates what character
+sequences the \eR escape sequence matches by default. A value of
+PCRE2_BSR_UNICODE means that \eR matches any Unicode line ending sequence; a
+value of PCRE2_BSR_ANYCRLF means that \eR matches only CR, LF, or CRLF. The
+default can be overridden when a pattern is compiled.
+.sp
+ PCRE2_CONFIG_JIT
+.sp
+The output is a uint32_t integer that is set to one if support for just-in-time
+compiling is available; otherwise it is set to zero.
+.sp
+ PCRE2_CONFIG_JITTARGET
+.sp
+The \fIwhere\fP argument should point to a buffer that is at least 48 code
+units long. (The exact length required can be found by calling
+\fBpcre2_config()\fP with \fBwhere\fP set to NULL.) The buffer is filled with a
+string that contains the name of the architecture for which the JIT compiler is
+configured, for example "x86 32bit (little endian + unaligned)". If JIT support
+is not available, PCRE2_ERROR_BADOPTION is returned, otherwise the number of
+code units used is returned. This is the length of the string, plus one unit
+for the terminating zero.
+.sp
+ PCRE2_CONFIG_LINKSIZE
+.sp
+The output is a uint32_t integer that contains the number of bytes used for
+internal linkage in compiled regular expressions. When PCRE2 is configured, the
+value can be set to 2, 3, or 4, with the default being 2. This is the value
+that is returned by \fBpcre2_config()\fP. However, when the 16-bit library is
+compiled, a value of 3 is rounded up to 4, and when the 32-bit library is
+compiled, internal linkages always use 4 bytes, so the configured value is not
+relevant.
+.P
+The default value of 2 for the 8-bit and 16-bit libraries is sufficient for all
+but the most massive patterns, since it allows the size of the compiled pattern
+to be up to 64K code units. Larger values allow larger regular expressions to
+be compiled by those two libraries, but at the expense of slower matching.
+.sp
+ PCRE2_CONFIG_MATCHLIMIT
+.sp

+ PCRE2_NEWLINE_ANY Any Unicode line ending
+ PCRE2_NEWLINE_ANYCRLF Any of CR, LF, or CRLF
+.sp
+The default should normally correspond to the standard sequence for your
+operating system.
+.sp
+ PCRE2_CONFIG_PARENSLIMIT
+.sp
+The output is a uint32_t integer that gives the maximum depth of nesting
+of parentheses (of any kind) in a pattern. This limit is imposed to cap the
+amount of system stack used when a pattern is compiled. It is specified when
+PCRE2 is built; the default is 250. This limit does not take into account the
+stack that may already be used by the calling application. For finer control
+over compilation stack usage, see \fBpcre2_set_compile_recursion_guard()\fP.
+.sp
+ PCRE2_CONFIG_RECURSIONLIMIT
+.sp
+The output is a uint32_t integer that gives the default limit for the depth of

+execution. Further details are given with \fBpcre2_match()\fP below.
+.sp
+ PCRE2_CONFIG_STACKRECURSE
+.sp
+The output is a uint32_t integer that is set to one if internal recursion when
+running \fBpcre2_match()\fP is implemented by recursive function calls that use
+the system stack to remember their state. This is the usual way that PCRE2 is
+compiled. The output is zero if PCRE2 was compiled to use blocks of data on the
+heap instead of recursive function calls.
+.sp
+ PCRE2_CONFIG_UNICODE_VERSION
+.sp
+The \fIwhere\fP argument should point to a buffer that is at least 24 code

+.sp
+ PCRE2_CONFIG_UNICODE
+.sp
+The output is a uint32_t integer that is set to one if Unicode support is

+.P
+If the compile context argument \fIccontext\fP is NULL, memory for the compiled
+pattern is obtained by calling \fBmalloc()\fP. Otherwise, it is obtained from
+the same memory function that was used for the compile context.
+.P
+The \fIoptions\fP argument contains various bit settings that affect the
+compilation. It should be zero if no options are required. The available
+options are described below. Some of them (in particular, those that are
+compatible with Perl, but some others as well) can also be set and unset from
+within the pattern (see the detailed description in the
+.\" HREF
+\fBpcre2pattern\fP
+.\"
+documentation).
+.P
+For those options that can be different in different parts of the pattern, the

+.P
+If \fIerrorcode\fP or \fIerroroffset\fP is NULL, \fBpcre2_compile()\fP returns
+NULL immediately. Otherwise, if compilation of a pattern fails,
+\fBpcre2_compile()\fP returns NULL, having set these variables to an error code
+and an offset (number of code units) within the pattern, respectively. The
+\fBpcre2_get_error_message()\fP function provides a textual message for each
+error code. Compilation errors are positive numbers, but UTF formatting errors
+are negative numbers. For an invalid UTF-8 or UTF-16 string, the offset is that
+of the first code unit of the failing character.
+.P
+Some errors are not detected until the whole pattern has been scanned; in these
+cases, the offset passed back is the length of the pattern. Note that the
+offset is in code units, not characters, even in a UTF mode. It may sometimes
+point into the middle of a UTF-8 or UTF-16 character.
+.P
+This code fragment shows a typical straightforward call to
+\fBpcre2_compile()\fP:

+ re = pcre2_compile(
+ "^A.*Z", /* the pattern */
+ PCRE2_ZERO_TERMINATED, /* the pattern is zero-terminated */
+ 0, /* default options */
+ &errorcode, /* for error code */
+ &erroffset, /* for error offset */
+ NULL); /* no compile context */
+.sp
+The following names for option bits are defined in the \fBpcre2.h\fP header
+file:
+.sp
+ PCRE2_ANCHORED
+.sp
+If this bit is set, the pattern is forced to be "anchored", that is, it is
+constrained to match only at the first matching point in the string that is
+being searched (the "subject string"). This effect can also be achieved by
+appropriate constructs in the pattern itself, which is the only way to do it in
+Perl.
+.sp
+ PCRE2_ALLOW_EMPTY_CLASS
+.sp
+By default, for compatibility with Perl, a closing square bracket that
+immediately follows an opening one is treated as a data character for the
+class. When PCRE2_ALLOW_EMPTY_CLASS is set, it terminates the class, which
+therefore contains no characters and so can never match.
+.sp
+ PCRE2_ALT_BSUX
+.sp
+This option request alternative handling of three escape sequences, which
+makes PCRE2's behaviour more like ECMAscript (aka JavaScript). When it is set:
+.P
+(1) \eU matches an upper case "U" character; by default \eU causes a compile
+time error (Perl uses \eU to upper case subsequent characters).
+.P
+(2) \eu matches a lower case "u" character unless it is followed by four
+hexadecimal digits, in which case the hexadecimal number defines the code point
+to match. By default, \eu causes a compile time error (Perl uses it to upper
+case the following character).
+.P
+(3) \ex matches a lower case "x" character unless it is followed by two
+hexadecimal digits, in which case the hexadecimal number defines the code point
+to match. By default, as in Perl, a hexadecimal number is always expected after
+\ex, but it may have zero, one, or two digits (so, for example, \exz matches a
+binary zero character followed by z).
+.sp
+ PCRE2_ALT_CIRCUMFLEX
+.sp
+In multiline mode (when PCRE2_MULTILINE is set), the circumflex metacharacter
+matches at the start of the subject (unless PCRE2_NOTBOL is set), and also
+after any internal newline. However, it does not match after a newline at the
+end of the subject, for compatibility with Perl. If you want a multiline
+circumflex also to match after a terminating newline, you must set
+PCRE2_ALT_CIRCUMFLEX.
+.sp
+ PCRE2_ALT_VERBNAMES
+.sp
+By default, for compatibility with Perl, the name in any verb sequence such as
+(*MARK:NAME) is any sequence of characters that does not include a closing
+parenthesis. The name is not processed in any way, and it is not possible to
+include a closing parenthesis in the name. However, if the PCRE2_ALT_VERBNAMES
+option is set, normal backslash processing is applied to verb names and only an
+unescaped closing parenthesis terminates the name. A closing parenthesis can be
+included in a name either as \e) or between \eQ and \eE. If the PCRE2_EXTENDED
+option is set, unescaped whitespace in verb names is skipped and #-comments are
+recognized, exactly as in the rest of the pattern.
+.sp
+ PCRE2_AUTO_CALLOUT
+.sp
+If this bit is set, \fBpcre2_compile()\fP automatically inserts callout items,
+all with number 255, before each pattern item. For discussion of the callout
+facility, see the
+.\" HREF
+\fBpcre2callout\fP
+.\"
+documentation.
+.sp
+ PCRE2_CASELESS
+.sp
+If this bit is set, letters in the pattern match both upper and lower case
+letters in the subject. It is equivalent to Perl's /i option, and it can be
+changed within a pattern by a (?i) option setting.
+.sp
+ PCRE2_DOLLAR_ENDONLY
+.sp
+If this bit is set, a dollar metacharacter in the pattern matches only at the
+end of the subject string. Without this option, a dollar also matches
+immediately before a newline at the end of the string (but not before any other
+newlines). The PCRE2_DOLLAR_ENDONLY option is ignored if PCRE2_MULTILINE is
+set. There is no equivalent to this option in Perl, and no way to set it within
+a pattern.
+.sp
+ PCRE2_DOTALL
+.sp
+If this bit is set, a dot metacharacter in the pattern matches any character,
+including one that indicates a newline. However, it only ever matches one
+character, even if newlines are coded as CRLF. Without this option, a dot does
+not match when the current position in the subject is at a newline. This option
+is equivalent to Perl's /s option, and it can be changed within a pattern by a
+(?s) option setting. A negative class such as [^a] always matches newline
+characters, independent of the setting of this option.
+.sp
+ PCRE2_DUPNAMES
+.sp
+If this bit is set, names used to identify capturing subpatterns need not be
+unique. This can be helpful for certain types of pattern when it is known that
+only one instance of the named subpattern can ever be matched. There are more
+details of named subpatterns below; see also the
+.\" HREF
+\fBpcre2pattern\fP
+.\"
+documentation.
+.sp
+ PCRE2_EXTENDED
+.sp
+If this bit is set, most white space characters in the pattern are totally
+ignored except when escaped or inside a character class. However, white space
+is not allowed within sequences such as (?> that introduce various
+parenthesized subpatterns, nor within numerical quantifiers such as {1,3}.
+Ignorable white space is permitted between an item and a following quantifier
+and between a quantifier and a following + that indicates possessiveness.
+.P
+PCRE2_EXTENDED also causes characters between an unescaped # outside a
+character class and the next newline, inclusive, to be ignored, which makes it
+possible to include comments inside complicated patterns. Note that the end of
+this type of comment is a literal newline sequence in the pattern; escape
+sequences that happen to represent a newline do not count. PCRE2_EXTENDED is
+equivalent to Perl's /x option, and it can be changed within a pattern by a
+(?x) option setting.
+.P
+Which characters are interpreted as newlines can be specified by a setting in
+the compile context that is passed to \fBpcre2_compile()\fP or by a special
+sequence at the start of the pattern, as described in the section entitled
+.\" HTML <a href="pcre2pattern.html#newlines">
+.\" </a>
+"Newline conventions"
+.\"
+in the \fBpcre2pattern\fP documentation. A default is defined when PCRE2 is
+built.
+.sp
+ PCRE2_FIRSTLINE
+.sp
+If this option is set, an unanchored pattern is required to match before or at
+the first newline in the subject string, though the matched text may continue
+over the newline. See also PCRE2_USE_OFFSET_LIMIT, which provides a more
+general limiting facility. If PCRE2_FIRSTLINE is set with an offset limit, a
+match must occur in the first line and also within the offset limit. In other
+words, whichever limit comes first is used.
+.sp
+ PCRE2_MATCH_UNSET_BACKREF
+.sp
+If this option is set, a back reference to an unset subpattern group matches an
+empty string (by default this causes the current matching alternative to fail).
+A pattern such as (\e1)(a) succeeds when this option is set (assuming it can
+find an "a" in the subject), whereas it fails by default, for Perl
+compatibility. Setting this option makes PCRE2 behave more like ECMAscript (aka
+JavaScript).
+.sp
+ PCRE2_MULTILINE
+.sp
+By default, for the purposes of matching "start of line" and "end of line",
+PCRE2 treats the subject string as consisting of a single line of characters,
+even if it actually contains newlines. The "start of line" metacharacter (^)
+matches only at the start of the string, and the "end of line" metacharacter
+($) matches only at the end of the string, or before a terminating newline
+(except when PCRE2_DOLLAR_ENDONLY is set). Note, however, that unless
+PCRE2_DOTALL is set, the "any character" metacharacter (.) does not match at a
+newline. This behaviour (for ^, $, and dot) is the same as Perl.
+.P
+When PCRE2_MULTILINE it is set, the "start of line" and "end of line"
+constructs match immediately following or immediately before internal newlines
+in the subject string, respectively, as well as at the very start and end. This
+is equivalent to Perl's /m option, and it can be changed within a pattern by a
+(?m) option setting. Note that the "start of line" metacharacter does not match
+after a newline at the end of the subject, for compatibility with Perl.
+However, you can change this by setting the PCRE2_ALT_CIRCUMFLEX option. If
+there are no newlines in a subject string, or no occurrences of ^ or $ in a
+pattern, setting PCRE2_MULTILINE has no effect.
+.sp
+ PCRE2_NEVER_BACKSLASH_C
+.sp
+This option locks out the use of \eC in the pattern that is being compiled.
+This escape can cause unpredictable behaviour in UTF-8 or UTF-16 modes, because
+it may leave the current matching point in the middle of a multi-code-unit
+character. This option may be useful in applications that process patterns from
+external sources. Note that there is also a build-time option that permanently
+locks out the use of \eC.
+.sp
+ PCRE2_NEVER_UCP
+.sp
+This option locks out the use of Unicode properties for handling \eB, \eb, \eD,
+\ed, \eS, \es, \eW, \ew, and some of the POSIX character classes, as described
+for the PCRE2_UCP option below. In particular, it prevents the creator of the
+pattern from enabling this facility by starting the pattern with (*UCP). This
+option may be useful in applications that process patterns from external
+sources. The option combination PCRE_UCP and PCRE_NEVER_UCP causes an error.
+.sp
+ PCRE2_NEVER_UTF
+.sp
+This option locks out interpretation of the pattern as UTF-8, UTF-16, or
+UTF-32, depending on which library is in use. In particular, it prevents the
+creator of the pattern from switching to UTF interpretation by starting the
+pattern with (*UTF). This option may be useful in applications that process
+patterns from external sources. The combination of PCRE2_UTF and
+PCRE2_NEVER_UTF causes an error.
+.sp
+ PCRE2_NO_AUTO_CAPTURE
+.sp
+If this option is set, it disables the use of numbered capturing parentheses in
+the pattern. Any opening parenthesis that is not followed by ? behaves as if it
+were followed by ?: but named parentheses can still be used for capturing (and
+they acquire numbers in the usual way). There is no equivalent of this option
+in Perl.
+.sp
+ PCRE2_NO_AUTO_POSSESS
+.sp
+If this option is set, it disables "auto-possessification", which is an
+optimization that, for example, turns a+b into a++b in order to avoid
+backtracks into a+ that can never be successful. However, if callouts are in
+use, auto-possessification means that some callouts are never taken. You can
+set this option if you want the matching functions to do a full unoptimized
+search and run all the callouts, but it is mainly provided for testing
+purposes.
+.sp
+ PCRE2_NO_DOTSTAR_ANCHOR
+.sp
+If this option is set, it disables an optimization that is applied when .* is
+the first significant item in a top-level branch of a pattern, and all the
+other branches also start with .* or with \eA or \eG or ^. The optimization is
+automatically disabled for .* if it is inside an atomic group or a capturing
+group that is the subject of a back reference, or if the pattern contains
+(*PRUNE) or (*SKIP). When the optimization is not disabled, such a pattern is
+automatically anchored if PCRE2_DOTALL is set for all the .* items and
+PCRE2_MULTILINE is not set for any ^ items. Otherwise, the fact that any match
+must start either at the start of the subject or following a newline is
+remembered. Like other optimizations, this can cause callouts to be skipped.
+.sp
+ PCRE2_NO_START_OPTIMIZE
+.sp
+This is an option whose main effect is at matching time. It does not change
+what \fBpcre2_compile()\fP generates, but it does affect the output of the JIT
+compiler.
+.P
+There are a number of optimizations that may occur at the start of a match, in
+order to speed up the process. For example, if it is known that an unanchored
+match must start with a specific character, the matching code searches the
+subject for that character, and fails immediately if it cannot find it, without
+actually running the main matching function. This means that a special item
+such as (*COMMIT) at the start of a pattern is not considered until after a
+suitable starting point for the match has been found. Also, when callouts or
+(*MARK) items are in use, these "start-up" optimizations can cause them to be
+skipped if the pattern is never actually used. The start-up optimizations are
+in effect a pre-scan of the subject that takes place before the pattern is run.
+.P
+The PCRE2_NO_START_OPTIMIZE option disables the start-up optimizations,
+possibly causing performance to suffer, but ensuring that in cases where the
+result is "no match", the callouts do occur, and that items such as (*COMMIT)
+and (*MARK) are considered at every possible starting position in the subject
+string.
+.P
+Setting PCRE2_NO_START_OPTIMIZE may change the outcome of a matching operation.
+Consider the pattern
+.sp
+ (*COMMIT)ABC
+.sp
+When this is compiled, PCRE2 records the fact that a match must start with the
+character "A". Suppose the subject string is "DEFABC". The start-up
+optimization scans along the subject, finds "A" and runs the first match
+attempt from there. The (*COMMIT) item means that the pattern must match the
+current starting position, which in this case, it does. However, if the same
+match is run with PCRE2_NO_START_OPTIMIZE set, the initial scan along the
+subject string does not happen. The first match attempt is run starting from
+"D" and when this fails, (*COMMIT) prevents any further matches being tried, so
+the overall result is "no match". There are also other start-up optimizations.
+For example, a minimum length for the subject may be recorded. Consider the
+pattern
+.sp
+ (*MARK:A)(X|Y)
+.sp
+The minimum length for a match is one character. If the subject is "ABC", there
+will be attempts to match "ABC", "BC", and "C". An attempt to match an empty
+string at the end of the subject does not take place, because PCRE2 knows that
+the subject is now too short, and so the (*MARK) is never encountered. In this
+case, the optimization does not affect the overall match result, which is still
+"no match", but it does affect the auxiliary information that is returned.
+.sp
+ PCRE2_NO_UTF_CHECK
+.sp
+When PCRE2_UTF is set, the validity of the pattern as a UTF string is
+automatically checked. There are discussions about the validity of
+.\" HTML <a href="pcre2unicode.html#utf8strings">
+.\" </a>
+UTF-8 strings,

+in the
+.\" HREF
+\fBpcre2unicode\fP
+.\"
+document.
+If an invalid UTF sequence is found, \fBpcre2_compile()\fP returns a negative
+error code.
+.P
+If you know that your pattern is valid, and you want to skip this check for
+performance reasons, you can set the PCRE2_NO_UTF_CHECK option. When it is set,
+the effect of passing an invalid UTF string as a pattern is undefined. It may
+cause your program to crash or loop. Note that this option can also be passed
+to \fBpcre2_match()\fP and \fBpcre_dfa_match()\fP, to suppress validity
+checking of the subject string.
+.sp
+ PCRE2_UCP
+.sp
+This option changes the way PCRE2 processes \eB, \eb, \eD, \ed, \eS, \es, \eW,
+\ew, and some of the POSIX character classes. By default, only ASCII characters
+are recognized, but if PCRE2_UCP is set, Unicode properties are used instead to
+classify characters. More details are given in the section on
+.\" HTML <a href="pcre2pattern.html#genericchartypes">
+.\" </a>
+generic character types
+.\"
+in the
+.\" HREF
+\fBpcre2pattern\fP

+page. If you set PCRE2_UCP, matching one of the items it affects takes much
+longer. The option is available only if PCRE2 has been compiled with Unicode
+support.
+.sp
+ PCRE2_UNGREEDY
+.sp
+This option inverts the "greediness" of the quantifiers so that they are not
+greedy by default, but become greedy if followed by "?". It is not compatible
+with Perl. It can also be set by a (?U) option setting within the pattern.
+.sp
+ PCRE2_USE_OFFSET_LIMIT
+.sp
+This option must be set for \fBpcre2_compile()\fP if
+\fBpcre2_set_offset_limit()\fP is going to be used to set a non-default offset
+limit in a match context for matches that use this pattern. An error is
+generated if an offset limit is set without this option. For more details, see

+option above.
+.sp
+ PCRE2_UTF
+.sp
+This option causes PCRE2 to regard both the pattern and the subject strings
+that are subsequently processed as strings of UTF characters instead of
+single-code-unit strings. It is available when PCRE2 is built to include
+Unicode support (which is the default). If Unicode support is not available,

+JIT compilation is a heavyweight optimization. It can take some time for

+.SH "LOCALE SUPPORT"
+.rs
+.sp
+PCRE2 handles caseless matching, and determines whether characters are letters,
+digits, or whatever, by reference to a set of tables, indexed by character code
+point. This applies only to characters whose code points are less than 256. By
+default, higher-valued code points never match escapes such as \ew or \ed.
+However, if PCRE2 is built with UTF support, all characters can be tested with
+\ep and \eP, or, alternatively, the PCRE2_UCP option can be set when a pattern
+is compiled; this causes \ew and friends to use Unicode property support
+instead of the built-in tables.
+.P
+The use of locales with Unicode is discouraged. If you are handling characters
+with code points greater than 128, you should either use Unicode support, or
+use locales, but not try to mix the two.
+.P
+PCRE2 contains an internal set of character tables that are used by default.
+These are sufficient for many applications. Normally, the internal tables
+recognize only ASCII characters. However, when PCRE2 is built, it is possible

+The internal tables can be overridden by tables supplied by the application
+that calls PCRE2. These may be created in a different locale from the default.
+As more and more applications change to using Unicode, the need for this locale
+support is expected to die away.
+.P
+External tables are built by calling the \fBpcre2_maketables()\fP function, in
+the relevant locale. The result can be passed to \fBpcre2_compile()\fP as often
+as necessary, by creating a compile context and calling
+\fBpcre2_set_character_tables()\fP to set the tables pointer therein. For
+example, to build and use tables that are appropriate for the French locale
+(where accented characters with values greater than 128 are treated as
+letters), the following code could be used:
+.sp
+ setlocale(LC_CTYPE, "fr_FR");
+ tables = pcre2_maketables(NULL);
+ ccontext = pcre2_compile_context_create(NULL);
+ pcre2_set_character_tables(ccontext, tables);
+ re = pcre2_compile(..., ccontext);
+.sp
+The locale name "fr_FR" is used on Linux and other Unix-like systems; if you
+are using Windows, the name for the French locale is "french". It is the
+caller's responsibility to ensure that the memory containing the tables remains
+available for as long as it is needed.
+.P
+The pointer that is passed (via the compile context) to \fBpcre2_compile()\fP
+is saved with the compiled pattern, and the same tables are used by
+\fBpcre2_match()\fP and \fBpcre_dfa_match()\fP. Thus, for any single pattern,
+compilation, and matching all happen in the same locale, but different patterns
+can be processed in different locales.

+The \fBpcre2_pattern_info()\fP function returns general information about a
+compiled pattern. For information about callouts, see the
+.\" HTML <a href="pcre2pattern.html#infoaboutcallouts">
+.\" </a>
+next section.
+.\"
+The first argument for \fBpcre2_pattern_info()\fP is a pointer to the compiled
+pattern. The second argument specifies which piece of information is required,
+and the third argument is a pointer to a variable to receive the data. If the
+third argument is NULL, the first argument is ignored, and the function returns
+the size in bytes of the variable that is required for the information
+requested. Otherwise, The yield of the function is zero for success, or one of
+the following negative numbers:
+.sp
+ PCRE2_ERROR_NULL the argument \fIcode\fP was NULL
+ PCRE2_ERROR_BADMAGIC the "magic number" was not found
+ PCRE2_ERROR_BADOPTION the value of \fIwhat\fP was invalid
+ PCRE2_ERROR_UNSET the requested field is not set
+.sp
+The "magic number" is placed at the start of each compiled pattern as an simple
+check against passing an arbitrary memory pointer. Here is a typical call of
+\fBpcre2_pattern_info()\fP, to obtain the length of the compiled pattern:
+.sp
+ int rc;
+ size_t length;
+ rc = pcre2_pattern_info(
+ re, /* result of pcre2_compile() */
+ PCRE2_INFO_SIZE, /* what is required */
+ &length); /* where to put the data */
+.sp
+The possible values for the second argument are defined in \fBpcre2.h\fP, and
+are as follows:
+.sp
+ PCRE2_INFO_ALLOPTIONS
+ PCRE2_INFO_ARGOPTIONS
+.sp
+Return a copy of the pattern's options. The third argument should point to a
+\fBuint32_t\fP variable. PCRE2_INFO_ARGOPTIONS returns exactly the options that
+were passed to \fBpcre2_compile()\fP, whereas PCRE2_INFO_ALLOPTIONS returns
+the compile options as modified by any top-level option settings such as (*UTF)
+at the start of the pattern itself. For example, if the pattern /(*UTF)abc/ is
+compiled with the PCRE2_EXTENDED option, the result is PCRE2_EXTENDED and
+PCRE2_UTF.
+.P
+A pattern compiled without PCRE2_ANCHORED is automatically anchored by PCRE2 if
+the first significant item in every top-level branch is one of the following:
+.sp
+ ^ unless PCRE2_MULTILINE is set
+ \eA always
+ \eG always
+ .* sometimes - see below
+.sp
+When .* is the first significant item, anchoring is possible only when all the
+following are true:
+.sp
+ .* is not in an atomic group
+.\" JOIN
+ .* is not in a capturing group that is the subject
+ of a back reference
+ PCRE2_DOTALL is in force for .*
+ Neither (*PRUNE) nor (*SKIP) appears in the pattern.
+ PCRE2_NO_DOTSTAR_ANCHOR is not set.
+.sp
+For patterns that are auto-anchored, the PCRE2_ANCHORED bit is set in the
+options returned for PCRE2_INFO_ALLOPTIONS.
+.sp
+ PCRE2_INFO_BACKREFMAX
+.sp
+Return the number of the highest back reference in the pattern. The third
+argument should point to an \fBuint32_t\fP variable. Named subpatterns acquire
+numbers as well as names, and these count towards the highest back reference.
+Back references such as \e4 or \eg{12} match the captured characters of the
+given group, but in addition, the check that a capturing group is set in a
+conditional subpattern such as (?(3)a|b) is also a back reference. Zero is
+returned if there are no back references.
+.sp
+ PCRE2_INFO_BSR
+.sp
+The output is a uint32_t whose value indicates what character sequences the \eR
+escape sequence matches. A value of PCRE2_BSR_UNICODE means that \eR matches
+any Unicode line ending sequence; a value of PCRE2_BSR_ANYCRLF means that \eR
+matches only CR, LF, or CRLF.
+.sp
+ PCRE2_INFO_CAPTURECOUNT
+.sp
+Return the highest capturing subpattern number in the pattern. In patterns
+where (?| is not used, this is also the total number of capturing subpatterns.
+The third argument should point to an \fBuint32_t\fP variable.
+.sp
+ PCRE2_INFO_FIRSTBITMAP
+.sp
+In the absence of a single first code unit for a non-anchored pattern,
+\fBpcre2_compile()\fP may construct a 256-bit table that defines a fixed set of
+values for the first code unit in any match. For example, a pattern that starts
+with [abc] results in a table with three bits set. When code unit values
+greater than 255 are supported, the flag bit for 255 means "any code unit of
+value 255 or above". If such a table was constructed, a pointer to it is
+returned. Otherwise NULL is returned. The third argument should point to an
+\fBconst uint8_t *\fP variable.
+.sp
+ PCRE2_INFO_FIRSTCODETYPE
+.sp
+Return information about the first code unit of any matched string, for a
+non-anchored pattern. The third argument should point to an \fBuint32_t\fP
+variable. If there is a fixed first value, for example, the letter "c" from a
+pattern such as (cat|cow|coyote), 1 is returned, and the character value can be
+retrieved using PCRE2_INFO_FIRSTCODEUNIT. If there is no fixed first value, but
+it is known that a match can occur only at the start of the subject or
+following a newline in the subject, 2 is returned. Otherwise, and for anchored
+patterns, 0 is returned.
+.sp
+ PCRE2_INFO_FIRSTCODEUNIT
+.sp
+Return the value of the first code unit of any matched string in the situation
+where PCRE2_INFO_FIRSTCODETYPE returns 1; otherwise return 0. The third
+argument should point to an \fBuint32_t\fP variable. In the 8-bit library, the
+value is always less than 256. In the 16-bit library the value can be up to
+0xffff. In the 32-bit library in UTF-32 mode the value can be up to 0x10ffff,
+and up to 0xffffffff when not using UTF-32 mode.
+.sp
+ PCRE2_INFO_HASBACKSLASHC
+.sp
+Return 1 if the pattern contains any instances of \eC, otherwise 0. The third
+argument should point to an \fBuint32_t\fP variable.
+.sp
+ PCRE2_INFO_HASCRORLF
+.sp
+Return 1 if the pattern contains any explicit matches for CR or LF characters,
+otherwise 0. The third argument should point to an \fBuint32_t\fP variable. An
+explicit match is either a literal CR or LF character, or \er or \en.
+.sp
+ PCRE2_INFO_JCHANGED
+.sp
+Return 1 if the (?J) or (?-J) option setting is used in the pattern, otherwise
+0. The third argument should point to an \fBuint32_t\fP variable. (?J) and
+(?-J) set and unset the local PCRE2_DUPNAMES option, respectively.
+.sp
+ PCRE2_INFO_JITSIZE
+.sp
+If the compiled pattern was successfully processed by
+\fBpcre2_jit_compile()\fP, return the size of the JIT compiled code, otherwise
+return zero. The third argument should point to a \fBsize_t\fP variable.
+.sp
+ PCRE2_INFO_LASTCODETYPE
+.sp
+Returns 1 if there is a rightmost literal code unit that must exist in any
+matched string, other than at its start. The third argument should point to an
+\fBuint32_t\fP variable. If there is no such value, 0 is returned. When 1 is
+returned, the code unit value itself can be retrieved using
+PCRE2_INFO_LASTCODEUNIT. For anchored patterns, a last literal value is
+recorded only if it follows something of variable length. For example, for the
+pattern /^a\ed+z\ed+/ the returned value is 1 (with "z" returned from
+PCRE2_INFO_LASTCODEUNIT), but for /^a\edz\ed/ the returned value is 0.
+.sp
+ PCRE2_INFO_LASTCODEUNIT
+.sp
+Return the value of the rightmost literal data unit that must exist in any
+matched string, other than at its start, if such a value has been recorded. The
+third argument should point to an \fBuint32_t\fP variable. If there is no such
+value, 0 is returned.
+.sp
+ PCRE2_INFO_MATCHEMPTY
+.sp
+Return 1 if the pattern might match an empty string, otherwise 0. The third
+argument should point to an \fBuint32_t\fP variable. When a pattern contains
+recursive subroutine calls it is not always possible to determine whether or
+not it can match an empty string. PCRE2 takes a cautious approach and returns 1
+in such cases.
+.sp
+ PCRE2_INFO_MATCHLIMIT
+.sp
+If the pattern set a match limit by including an item of the form
+(*LIMIT_MATCH=nnnn) at the start, the value is returned. The third argument
+should point to an unsigned 32-bit integer. If no such value has been set, the
+call to \fBpcre2_pattern_info()\fP returns the error PCRE2_ERROR_UNSET.
+.sp
+ PCRE2_INFO_MAXLOOKBEHIND
+.sp
+Return the number of characters (not code units) in the longest lookbehind
+assertion in the pattern. The third argument should point to an unsigned 32-bit
+integer. This information is useful when doing multi-segment matching using the
+partial matching facilities. Note that the simple assertions \eb and \eB
+require a one-character lookbehind. \eA also registers a one-character
+lookbehind, though it does not actually inspect the previous character. This is
+to ensure that at least one character from the old segment is retained when a
+new segment is processed. Otherwise, if there are no lookbehinds in the
+pattern, \eA might match incorrectly at the start of a new segment.
+.sp
+ PCRE2_INFO_MINLENGTH
+.sp
+If a minimum length for matching subject strings was computed, its value is
+returned. Otherwise the returned value is 0. The value is a number of
+characters, which in UTF mode may be different from the number of code units.
+The third argument should point to an \fBuint32_t\fP variable. The value is a
+lower bound to the length of any matching string. There may not be any strings
+of that length that do actually match, but every string that does match is at
+least that long.
+.sp
+ PCRE2_INFO_NAMECOUNT
+ PCRE2_INFO_NAMEENTRYSIZE
+ PCRE2_INFO_NAMETABLE
+.sp
+PCRE2 supports the use of named as well as numbered capturing parentheses. The
+names are just an additional way of identifying the parentheses, which still
+acquire numbers. Several convenience functions such as
+\fBpcre2_substring_get_byname()\fP are provided for extracting captured
+substrings by name. It is also possible to extract the data directly, by first
+converting the name to a number in order to access the correct pointers in the
+output vector (described with \fBpcre2_match()\fP below). To do the conversion,
+you need to use the name-to-number map, which is described by these three
+values.
+.P
+The map consists of a number of fixed-size entries. PCRE2_INFO_NAMECOUNT gives
+the number of entries, and PCRE2_INFO_NAMEENTRYSIZE gives the size of each
+entry in code units; both of these return a \fBuint32_t\fP value. The entry
+size depends on the length of the longest name.
+.P
+PCRE2_INFO_NAMETABLE returns a pointer to the first entry of the table. This is
+a PCRE2_SPTR pointer to a block of code units. In the 8-bit library, the first
+two bytes of each entry are the number of the capturing parenthesis, most
+significant byte first. In the 16-bit library, the pointer points to 16-bit
+code units, the first of which contains the parenthesis number. In the 32-bit
+library, the pointer points to 32-bit code units, the first of which contains
+the parenthesis number. The rest of the entry is the corresponding name, zero
+terminated.
+.P
+The names are in alphabetical order. If (?| is used to create multiple groups
+with the same number, as described in the
+.\" HTML <a href="pcre2pattern.html#dupsubpatternnumber">
+.\" </a>
+section on duplicate subpattern numbers
+.\"
+in the
+.\" HREF
+\fBpcre2pattern\fP
+.\"
+page, the groups may be given the same name, but there is only one entry in the
+table. Different names for groups of the same number are not permitted.
+.P
+Duplicate names for subpatterns with different numbers are permitted, but only
+if PCRE2_DUPNAMES is set. They appear in the table in the order in which they
+were found in the pattern. In the absence of (?| this is the order of
+increasing number; when (?| is used this is not necessarily the case because
+later subpatterns may have lower numbers.
+.P
+As a simple example of the name/number table, consider the following pattern
+after compilation by the 8-bit library (assume PCRE2_EXTENDED is set, so white
+space - including newlines - is ignored):
+.sp
+.\" JOIN
+ (?<date> (?<year>(\ed\ed)?\ed\ed) -
+ (?<month>\ed\ed) - (?<day>\ed\ed) )
+.sp
+There are four named subpatterns, so the table has four entries, and each entry
+in the table is eight bytes long. The table is as follows, with non-printing
+bytes shows in hexadecimal, and undefined bytes shown as ??:
+.sp
+ 00 01 d a t e 00 ??
+ 00 05 d a y 00 ?? ??
+ 00 04 m o n t h 00
+ 00 02 y e a r 00 ??
+.sp
+When writing code to extract data from named subpatterns using the
+name-to-number map, remember that the length of the entries is likely to be
+different for each compiled pattern.
+.sp
+ PCRE2_INFO_NEWLINE
+.sp
+The output is a \fBuint32_t\fP with one of the following values:
+.sp
+ PCRE2_NEWLINE_CR Carriage return (CR)
+ PCRE2_NEWLINE_LF Linefeed (LF)
+ PCRE2_NEWLINE_CRLF Carriage return, linefeed (CRLF)
+ PCRE2_NEWLINE_ANY Any Unicode line ending
+ PCRE2_NEWLINE_ANYCRLF Any of CR, LF, or CRLF
+.sp
+This specifies the default character sequence that will be recognized as
+meaning "newline" while matching.
+.sp
+ PCRE2_INFO_RECURSIONLIMIT
+.sp
+If the pattern set a recursion limit by including an item of the form
+(*LIMIT_RECURSION=nnnn) at the start, the value is returned. The third
+argument should point to an unsigned 32-bit integer. If no such value has been
+set, the call to \fBpcre2_pattern_info()\fP returns the error PCRE2_ERROR_UNSET.
+.sp
+ PCRE2_INFO_SIZE
+.sp
+Return the size of the compiled pattern in bytes (for all three libraries). The
+third argument should point to a \fBsize_t\fP variable. This value includes the
+size of the general data block that precedes the code units of the compiled
+pattern itself. The value that is used when \fBpcre2_compile()\fP is getting
+memory in which to place the compiled pattern may be slightly larger than the
+value returned by this option, because there are cases where the code that
+calculates the size has to over-estimate. Processing a pattern with the JIT
+compiler does not alter the value returned by this option.

+captured. This is know as the \fIovector\fP.
+.P
+Before calling \fBpcre2_match()\fP, \fBpcre2_dfa_match()\fP, or
+\fBpcre2_jit_match()\fP you must create a match data block by calling one of
+the creation functions above. For \fBpcre2_match_data_create()\fP, the first
+argument is the number of pairs of offsets in the \fIovector\fP. One pair of
+offsets is required to identify the string that matched the whole pattern, with
+another pair for each captured substring. For example, a value of 4 creates
+enough space to record the matched portion of the subject plus three captured
+substrings. A minimum of at least 1 pair is imposed by
+\fBpcre2_match_data_create()\fP, so it is always possible to return the overall
+matched string.
+.P
+The second argument of \fBpcre2_match_data_create()\fP is a pointer to a
+general context, which can specify custom memory management for obtaining the
+memory for the match data block. If you are not using custom memory management,
+pass NULL, which causes \fBmalloc()\fP to be used.
+.P
+For \fBpcre2_match_data_create_from_pattern()\fP, the first argument is a
+pointer to a compiled pattern. The ovector is created to be exactly the right
+size to hold all the substrings a pattern might capture. The second argument is
+again a pointer to a general context, but in this case if NULL is passed, the
+memory is obtained using the same allocator that was used for the compiled
+pattern (custom or default).
+.P
+A match data block can be used many times, with the same or different compiled

+.\"
+above.
+.
+.
+.SS "The string to be matched by \fBpcre2_match()\fP"
+.rs
+.sp
+The subject string is passed to \fBpcre2_match()\fP as a pointer in
+\fIsubject\fP, a length in \fIlength\fP, and a starting offset in
+\fIstartoffset\fP. The length and offset are in code units, not characters.
+That is, they are in bytes for the 8-bit library, 16-bit code units for the
+16-bit library, and 32-bit code units for the 32-bit library, whether or not
+UTF processing is enabled.
+.P
+If \fIstartoffset\fP is greater than the length of the subject,
+\fBpcre2_match()\fP returns PCRE2_ERROR_BADOFFSET. When the starting offset is
+zero, the search for a match starts at the beginning of the subject, and this
+is by far the most common case. In UTF-8 or UTF-16 mode, the starting offset
+must point to the start of a character, or to the end of the subject (in UTF-32
+mode, one code unit equals one character, so all offsets are valid). Like the
+pattern string, the subject may contain binary zeroes.
+.P
+A non-zero starting offset is useful when searching for another match in the
+same subject by calling \fBpcre2_match()\fP again after a previous success.
+Setting \fIstartoffset\fP differs from passing over a shortened string and
+setting PCRE2_NOTBOL in the case of a pattern that begins with any kind of
+lookbehind. For example, consider the pattern
+.sp
+ \eBiss\eB
+.sp
+which finds occurrences of "iss" in the middle of words. (\eB matches only if
+the current position in the subject is not a word boundary.) When applied to
+the string "Mississipi" the first call to \fBpcre2_match()\fP finds the first
+occurrence. If \fBpcre2_match()\fP is called again with just the remainder of
+the subject, namely "issipi", it does not match, because \eB is always false at
+the start of the subject, which is deemed to be a word boundary. However, if
+\fBpcre2_match()\fP is passed the entire string again, but with
+\fIstartoffset\fP set to 4, it finds the second occurrence of "iss" because it
+is able to look behind the starting point to discover that it is preceded by a
+letter.
+.P
+Finding all the matches in a subject is tricky when the pattern can match an
+empty string. It is possible to emulate Perl's /g behaviour by first trying the
+match again at the same offset, with the PCRE2_NOTEMPTY_ATSTART and
+PCRE2_ANCHORED options, and then if that fails, advancing the starting offset
+and trying an ordinary match again. There is some code that demonstrates how to
+do this in the
+.\" HREF
+\fBpcre2demo\fP
+.\"
+sample program. In the most general case, you have to check to see if the
+newline convention recognizes CRLF as a newline, and if so, and the current
+character is CR followed by LF, advance the starting offset by two characters
+instead of one.
+.P
+If a non-zero starting offset is passed when the pattern is anchored, one
+attempt to match at the given offset is made. This can only succeed if the
+pattern does not require the match to be at the start of the subject.

+ PCRE2_ANCHORED
+.sp
+The PCRE2_ANCHORED option limits \fBpcre2_match()\fP to matching at the first
+matching position. If a pattern was compiled with PCRE2_ANCHORED, or turned out
+to be anchored by virtue of its contents, it cannot be made unachored at
+matching time. Note that setting the option at match time disables JIT
+matching.
+.sp
+ PCRE2_NOTBOL
+.sp
+This option specifies that first character of the subject string is not the
+beginning of a line, so the circumflex metacharacter should not match before
+it. Setting this without having set PCRE2_MULTILINE at compile time causes
+circumflex never to match. This option affects only the behaviour of the
+circumflex metacharacter. It does not affect \eA.
+.sp
+ PCRE2_NOTEOL
+.sp
+This option specifies that the end of the subject string is not the end of a
+line, so the dollar metacharacter should not match it nor (except in multiline
+mode) a newline immediately before it. Setting this without having set
+PCRE2_MULTILINE at compile time causes dollar never to match. This option
+affects only the behaviour of the dollar metacharacter. It does not affect \eZ
+or \ez.
+.sp
+ PCRE2_NOTEMPTY
+.sp
+An empty string is not considered to be a valid match if this option is set. If
+there are alternatives in the pattern, they are tried. If all the alternatives
+match the empty string, the entire match fails. For example, if the pattern
+.sp
+ a?b?
+.sp
+is applied to a string not beginning with "a" or "b", it matches an empty
+string at the start of the subject. With PCRE2_NOTEMPTY set, this match is not
+valid, so \fBpcre2_match()\fP searches further into the string for occurrences
+of "a" or "b".
+.sp
+ PCRE2_NOTEMPTY_ATSTART
+.sp
+This is like PCRE2_NOTEMPTY, except that it locks out an empty string match
+only at the first matching position, that is, at the start of the subject plus
+the starting offset. An empty string match later in the subject is permitted.
+If the pattern is anchored, such a match can occur only if the pattern contains
+\eK.
+.sp
+ PCRE2_NO_UTF_CHECK
+.sp
+When PCRE2_UTF is set at compile time, the validity of the subject as a UTF
+string is checked by default when \fBpcre2_match()\fP is subsequently called.
+If a non-zero starting offset is given, the check is applied only to that part
+of the subject that could be inspected during matching, and there is a check
+that the starting offset points to the first code unit of a character or to the
+end of the subject. If there are no lookbehind assertions in the pattern, the
+check starts at the starting offset. Otherwise, it starts at the length of the
+longest lookbehind before the starting offset, or at the start of the subject
+if there are not that many characters before the starting offset. Note that the
+sequences \eb and \eB are one-character lookbehinds.
+.P
+The check is carried out before any other processing takes place, and a
+negative error code is returned if the check fails. There are several UTF error
+codes for each code unit width, corresponding to different problems with the
+code unit sequence. There are discussions about the validity of

+in the

+page.
+.P
+If you know that your subject is valid, and you want to skip these checks for
+performance reasons, you can set the PCRE2_NO_UTF_CHECK option when calling
+\fBpcre2_match()\fP. You might want to do this for the second and subsequent
+calls to \fBpcre2_match()\fP if you are making repeated calls to find all the
+matches in a single subject string.
+.P
+NOTE: When PCRE2_NO_UTF_CHECK is set, the effect of passing an invalid string
+as a subject, or an invalid value of \fIstartoffset\fP, is undefined. Your
+program may crash or loop indefinitely.
+.sp
+ PCRE2_PARTIAL_HARD
+ PCRE2_PARTIAL_SOFT
+.sp
+These options turn on the partial matching feature. A partial match occurs if
+the end of the subject string is reached successfully, but there are not enough
+subject characters to complete the match. If this happens when
+PCRE2_PARTIAL_SOFT (but not PCRE2_PARTIAL_HARD) is set, matching continues by
+testing any remaining alternatives. Only if no complete match can be found is
+PCRE2_ERROR_PARTIAL returned instead of PCRE2_ERROR_NOMATCH. In other words,
+PCRE2_PARTIAL_SOFT specifies that the caller is prepared to handle a partial
+match, but only if no complete match can be found.
+.P
+If PCRE2_PARTIAL_HARD is set, it overrides PCRE2_PARTIAL_SOFT. In this case, if
+a partial match is found, \fBpcre2_match()\fP immediately returns
+PCRE2_ERROR_PARTIAL, without considering any other alternatives. In other
+words, when PCRE2_PARTIAL_HARD is set, a partial match is considered to be more
+important that an alternative complete match.
+.P
+There is a more detailed discussion of partial and multi-segment matching, with
+examples, in the

+.SH "NEWLINE HANDLING WHEN MATCHING"
+.rs
+.sp
+When PCRE2 is built, a default newline convention is set; this is usually the
+standard convention for the operating system. The default can be overridden in
+a
+.\" HTML <a href="#compilecontext">
+.\" </a>
+compile context
+.\"
+by calling \fBpcre2_set_newline()\fP. It can also be overridden by starting a
+pattern string with, for example, (*CRLF), as described in the
+.\" HTML <a href="pcre2pattern.html#newlines">
+.\" </a>
+section on newline conventions
+.\"
+in the
+.\" HREF
+\fBpcre2pattern\fP
+.\"
+page. During matching, the newline choice affects the behaviour of the dot,
+circumflex, and dollar metacharacters. It may also alter the way the match
+starting position is advanced after a match failure for an unanchored pattern.
+.P
+When PCRE2_NEWLINE_CRLF, PCRE2_NEWLINE_ANYCRLF, or PCRE2_NEWLINE_ANY is set as
+the newline convention, and a match attempt for an unanchored pattern fails
+when the current starting position is at a CRLF sequence, and the pattern
+contains no explicit matches for CR or LF characters, the match position is
+advanced by two characters instead of one, in other words, to after the CRLF.
+.P
+The above rule is a compromise that makes the most common cases work as
+expected. For example, if the pattern is .+A (and the PCRE2_DOTALL option is
+not set), it does not match the string "\er\enA" because, after failing at the
+start, it skips both the CR and the LF before retrying. However, the pattern
+[\er\en]A does match that string, because it contains an explicit CR or LF
+reference, and so advances only by one character after the first failure.
+.P
+An explicit match for CR of LF is either a literal appearance of one of those
+characters in the pattern, or one of the \er or \en escape sequences. Implicit
+matches such as [^X] do not count, nor does \es, even though it includes CR and
+LF in the characters that it matches.
+.P
+Notwithstanding the above, anomalous effects may still occur when CRLF is a
+valid newline sequence and explicit \er or \en escapes appear in the pattern.

+.fi
+.P
+In general, a pattern matches a certain portion of the subject, and in
+addition, further substrings from the subject may be picked out by
+parenthesized parts of the pattern. Following the usage in Jeffrey Friedl's
+book, this is called "capturing" in what follows, and the phrase "capturing
+subpattern" or "capturing group" is used for a fragment of a pattern that picks
+out a substring. PCRE2 supports several other kinds of parenthesized subpattern
+that do not cause substrings to be captured. The \fBpcre2_pattern_info()\fP
+function can be used to find out how many capturing subpatterns there are in a
+compiled pattern.
+.P
+You can use auxiliary functions for accessing captured substrings
+.\" HTML <a href="#extractbynumber">
+.\" </a>
+by number
+.\"
+or
+.\" HTML <a href="#extractbyname">
+.\" </a>
+by name,
+.\"
+as described in sections below.
+.P
+Alternatively, you can make direct use of the vector of PCRE2_SIZE values,
+called the \fBovector\fP, which contains the offsets of captured strings. It is
+part of the
+.\" HTML <a href="#matchdatablock">
+.\" </a>
+match data block.
+.\"
+The function \fBpcre2_get_ovector_pointer()\fP returns the address of the
+ovector, and \fBpcre2_get_ovector_count()\fP returns the number of pairs of
+values it contains.
+.P
+Within the ovector, the first in each pair of values is set to the offset of
+the first code unit of a substring, and the second is set to the offset of the
+first code unit after the end of a substring. These values are always code unit
+offsets, not character offsets. That is, they are byte offsets in the 8-bit
+library, 16-bit offsets in the 16-bit library, and 32-bit offsets in the 32-bit
+library.
+.P
+After a partial match (error return PCRE2_ERROR_PARTIAL), only the first pair
+of offsets (that is, \fIovector[0]\fP and \fIovector[1]\fP) are set. They
+identify the part of the subject that was partially matched. See the
+.\" HREF
+\fBpcre2partial\fP
+.\"
+documentation for details of partial matching.
+.P
+After a successful match, the first pair of offsets identifies the portion of
+the subject string that was matched by the entire pattern. The next pair is
+used for the first capturing subpattern, and so on. The value returned by
+\fBpcre2_match()\fP is one more than the highest numbered pair that has been
+set. For example, if two substrings have been captured, the returned value is
+3. If there are no capturing subpatterns, the return value from a successful
+match is 1, indicating that just the first pair of offsets has been set.
+.P
+If a pattern uses the \eK escape sequence within a positive assertion, the
+reported start of a successful match can be greater than the end of the match.
+For example, if the pattern (?=ab\eK) is matched against "ab", the start and
+end offset values for the match are 2 and 0.
+.P
+If a capturing subpattern group is matched repeatedly within a single match
+operation, it is the last portion of the subject that it matched that is
+returned.
+.P
+If the ovector is too small to hold all the captured substring offsets, as much
+as possible is filled in, and the function returns a value of zero. If captured
+substrings are not of interest, \fBpcre2_match()\fP may be called with a match
+data block whose ovector is of minimum length (that is, one pair). However, if
+the pattern contains back references and the \fIovector\fP is not big enough to
+remember the related substrings, PCRE2 has to get additional memory for use
+during matching. Thus it is usually advisable to set up a match data block
+containing an ovector of reasonable size.
+.P
+It is possible for capturing subpattern number \fIn+1\fP to match some part of
+the subject when subpattern \fIn\fP has not been used at all. For example, if
+the string "abc" is matched against the pattern (a|(z))(bc) the return from the
+function is 4, and subpatterns 1 and 3 are matched, but 2 is not. When this
+happens, both values in the offset pairs corresponding to unused subpatterns
+are set to PCRE2_UNSET.
+.P
+Offset values that correspond to unused subpatterns at the end of the
+expression are also set to PCRE2_UNSET. For example, if the string "abc" is
+matched against the pattern (abc)(x(yz)?)? subpatterns 2 and 3 are not matched.
+The return from the function is 2, because the highest used capturing
+subpattern number is 1. The offsets for for the second and third capturing
+subpatterns (assuming the vector is large enough, of course) are set to
+PCRE2_UNSET.
+.P
+Elements in the ovector that do not correspond to capturing parentheses in the
+pattern are never changed. That is, if a pattern contains \fIn\fP capturing
+parentheses, no more than \fIovector[0]\fP to \fIovector[2n+1]\fP are set by
+\fBpcre2_match()\fP. The other elements retain whatever values they previously
+had.

+.P
+After a successful match, a partial match (PCRE2_ERROR_PARTIAL), or a failure

+relying on the terminating zero if the (*MARK) name might contain a binary
+zero.
+.P
+After a successful match, the (*MARK) name that is returned is the
+last one encountered on the matching path through the pattern. After a "no
+match" or a partial match, the last encountered (*MARK) name is returned. For
+example, consider this pattern:
+.sp
+ ^(*MARK:A)((*MARK:B)a|b)c
+.sp
+When it matches "bc", the returned mark is A. The B mark is "seen" in the first
+branch of the group, but it is not on the matching path. On the other hand,
+when this pattern fails to match "bx", the returned mark is B.
+.P
+After a successful match, a partial match, or one of the invalid UTF errors
+(for example, PCRE2_ERROR_UTF8_ERR5), \fBpcre2_get_startchar()\fP can be
+called. After a successful or partial match it returns the code unit offset of
+the character at which the match started. For a non-partial match, this can be
+different to the value of \fIovector[0]\fP if the pattern contains the \eK
+escape sequence. After a partial match, however, this value is always the same
+as \fIovector[0]\fP because \eK does not affect the result of a partial match.

+For convenience, auxiliary functions are provided for extracting captured
+substrings as new, separate, zero-terminated strings. A substring that contains
+a binary zero is correctly extracted and has a further zero added on the end,
+but the result is not, of course, a C string.
+.P
+The functions in this section identify substrings by number. The number zero
+refers to the entire matched substring, with higher numbers referring to
+substrings captured by parenthesized groups. After a partial match, only
+substring zero is available. An attempt to extract any other substring gives
+the error PCRE2_ERROR_PARTIAL. The next section describes similar functions for
+extracting captured substrings by name.
+.P
+If a pattern uses the \eK escape sequence within a positive assertion, the
+reported start of a successful match can be greater than the end of the match.
+For example, if the pattern (?=ab\eK) is matched against "ab", the start and
+end offset values for the match are 2 and 0. In this situation, calling these
+functions with a zero substring number extracts a zero-length empty string.
+.P
+You can find the length in code units of a captured substring without
+extracting it by calling \fBpcre2_substring_length_bynumber()\fP. The first
+argument is a pointer to the match data block, the second is the group number,
+and the third is a pointer to a variable into which the length is placed. If
+you just want to know whether or not the substring has been captured, you can
+pass the third argument as NULL.
+.P
+The \fBpcre2_substring_copy_bynumber()\fP function copies a captured substring
+into a supplied buffer, whereas \fBpcre2_substring_get_bynumber()\fP copies it
+into new memory, obtained using the same memory allocation function that was
+used for the match data block. The first two arguments of these functions are a
+pointer to the match data block and a capturing group number.
+.P
+The final arguments of \fBpcre2_substring_copy_bynumber()\fP are a pointer to
+the buffer and a pointer to a variable that contains its length in code units.
+This is updated to contain the actual number of code units used for the
+extracted substring, excluding the terminating zero.
+.P
+For \fBpcre2_substring_get_bynumber()\fP the third and fourth arguments point
+to variables that are updated with a pointer to the new memory and the number
+of code units that comprise the substring, again excluding the terminating
+zero. When the substring is no longer needed, the memory should be freed by
+calling \fBpcre2_substring_free()\fP.
+.P
+The return value from all these functions is zero for success, or a negative
+error code. If the pattern match failed, the match failure code is returned.
+If a substring number greater than zero is used after a partial match,
+PCRE2_ERROR_PARTIAL is returned. Other possible error codes are:
+.sp
+ PCRE2_ERROR_NOMEMORY

+The buffer was too small for \fBpcre2_substring_copy_bynumber()\fP, or the

+ PCRE2_ERROR_NOSUBSTRING
+.sp
+There is no substring with that number in the pattern, that is, the number is
+greater than the number of capturing parentheses.
+.sp
+ PCRE2_ERROR_UNAVAILABLE
+.sp
+The substring number, though not greater than the number of captures in the
+pattern, is greater than the number of slots in the ovector, so the substring
+could not be captured.
+.sp
+ PCRE2_ERROR_UNSET

+that is obtained using the same memory allocation function that was used to get

+.P
+The address of the memory block is returned via \fIlistptr\fP, which is also
+the start of the list of string pointers. The end of the list is marked by a

+therefore need the lengths, you may supply NULL as the \fBlengthsptr\fP
+argument to disable the creation of a list of lengths. The yield of the
+function is zero if all went well, or PCRE2_ERROR_NOMEMORY if the memory block
+could not be obtained. When the list is no longer needed, it should be freed by

+To extract a substring by name, you first have to find associated number.
+For example, for this pattern:
+.sp
+ (a+)b(?<xxx>\ed+)...
+.sp
+the number of the subpattern called "xxx" is 2. If the name is known to be
+unique (PCRE2_DUPNAMES was not set), you can find the number from the name by
+calling \fBpcre2_substring_number_from_name()\fP. The first argument is the
+compiled pattern, and the second is the name. The yield of the function is the
+subpattern number, PCRE2_ERROR_NOSUBSTRING if there is no subpattern of that
+name, or PCRE2_ERROR_NOUNIQUESUBSTRING if there is more than one subpattern of
+that name. Given the number, you can extract the substring directly, or use one
+of the functions described above.
+.P
+For convenience, there are also "byname" functions that correspond to the
+"bynumber" functions, the only difference being that the second argument is a
+name instead of a number. If PCRE2_DUPNAMES is set and there are duplicate
+names, these functions scan all the groups with the given name, and return the
+first named string that is set.
+.P
+If there are no groups with the given name, PCRE2_ERROR_NOSUBSTRING is
+returned. If all groups with the name have numbers that are greater than the
+number of slots in the ovector, PCRE2_ERROR_UNAVAILABLE is returned. If there
+is at least one group with a slot in the ovector, but no group is found to be
+set, PCRE2_ERROR_UNSET is returned.
+.P
+\fBWarning:\fP If the pattern uses the (?| feature to set up multiple
+subpatterns with the same number, as described in the
+.\" HTML <a href="pcre2pattern.html#dupsubpatternnumber">
+.\" </a>
+section on duplicate subpattern numbers
+.\"
+in the
+.\" HREF
+\fBpcre2pattern\fP
+.\"
+page, you cannot use names to distinguish the different subpatterns, because
+names are not included in the compiled code. The matching process uses only
+numbers. For this reason, the use of different names for subpatterns of the
+same number causes an error at compile time.

+.fi
+.P
+This function calls \fBpcre2_match()\fP and then makes a copy of the subject
+string in \fIoutputbuffer\fP, replacing the part that was matched with the
+\fIreplacement\fP string, whose length is supplied in \fBrlength\fP. This can
+be given as PCRE2_ZERO_TERMINATED for a zero-terminated string. Matches in
+which a \eK item in a lookahead in the pattern causes the match to end before
+it starts are not supported, and give rise to an error return.
+.P
+The first seven arguments of \fBpcre2_substitute()\fP are the same as for
+\fBpcre2_match()\fP, except that the partial matching options are not
+permitted, and \fImatch_data\fP may be passed as NULL, in which case a match
+data block is obtained and freed within this function, using memory management
+functions from the match context, if provided, or else those that were used to
+allocate memory for the compiled code.
+.P
+The \fIoutlengthptr\fP argument must point to a variable that contains the
+length, in code units, of the output buffer. If the function is successful, the
+value is updated to contain the length of the new string, excluding the
+trailing zero that is automatically added.
+.P
+If the function is not successful, the value set via \fIoutlengthptr\fP depends
+on the type of error. For syntax errors in the replacement string, the value is
+the offset in the replacement string where the error was detected. For other
+errors, the value is PCRE2_UNSET by default. This includes the case of the
+output buffer being too small, unless PCRE2_SUBSTITUTE_OVERFLOW_LENGTH is set
+(see below), in which case the value is the minimum length needed, including
+space for the trailing zero. Note that in order to compute the required length,
+\fBpcre2_substitute()\fP has to simulate all the matching and copying, instead
+of giving an error return as soon as the buffer overflows. Note also that the
+length is in code units, not bytes.
+.P
+In the replacement string, which is interpreted as a UTF string in UTF mode,
+and is checked for UTF validity unless the PCRE2_NO_UTF_CHECK option is set, a
+dollar character is an escape character that can specify the insertion of
+characters from capturing groups or (*MARK) items in the pattern. The following
+forms are always recognized:
+.sp
+ $$ insert a dollar character
+ $<n> or ${<n>} insert the contents of group <n>
+ $*MARK or ${*MARK} insert the name of the last (*MARK) encountered
+.sp
+Either a group number or a group name can be given for <n>. Curly brackets are
+required only if the following character would be interpreted as part of the
+number or name. The number may be zero to include the entire matched string.
+For example, if the pattern a(b)c is matched with "=abc=" and the replacement
+string "+$1$0$1+", the result is "=+babcb+=".
+.P
+The facility for inserting a (*MARK) name can be used to perform simple
+simultaneous substitutions, as this \fBpcre2test\fP example shows:
+.sp
+ /(*:pear)apple|(*:orange)lemon/g,replace=${*MARK}
+ apple lemon
+ 2: pear orange
+.sp
+As well as the usual options for \fBpcre2_match()\fP, a number of additional
+options can be set in the \fIoptions\fP argument.
+.P
+PCRE2_SUBSTITUTE_GLOBAL causes the function to iterate over the subject string,
+replacing every matching substring. If this is not set, only the first matching
+substring is replaced. If any matched substring has zero length, after the
+substitution has happened, an attempt to find a non-empty match at the same
+position is performed. If this is not successful, the current position is
+advanced by one character except when CRLF is a valid newline sequence and the
+next two characters are CR, LF. In this case, the current position is advanced
+by two characters.
+.P
+PCRE2_SUBSTITUTE_OVERFLOW_LENGTH changes what happens when the output buffer is
+too small. The default action is to return PCRE2_ERROR_NOMEMORY immediately. If
+this option is set, however, \fBpcre2_substitute()\fP continues to go through
+the motions of matching and substituting (without, of course, writing anything)
+in order to compute the size of buffer that is needed. This value is passed
+back via the \fIoutlengthptr\fP variable, with the result of the function still
+being PCRE2_ERROR_NOMEMORY.
+.P
+Passing a buffer size of zero is a permitted way of finding out how much memory
+is needed for given substitution. However, this does mean that the entire
+operation is carried out twice. Depending on the application, it may be more
+efficient to allocate a large buffer and free the excess afterwards, instead of
+using PCRE2_SUBSTITUTE_OVERFLOW_LENGTH.
+.P
+PCRE2_SUBSTITUTE_UNKNOWN_UNSET causes references to capturing groups that do
+not appear in the pattern to be treated as unset groups. This option should be
+used with care, because it means that a typo in a group name or number no
+longer causes the PCRE2_ERROR_NOSUBSTRING error.
+.P
+PCRE2_SUBSTITUTE_UNSET_EMPTY causes unset capturing groups (including unknown
+groups when PCRE2_SUBSTITUTE_UNKNOWN_UNSET is set) to be treated as empty
+strings when inserted as described above. If this option is not set, an attempt
+to insert an unset group causes the PCRE2_ERROR_UNSET error. This option does
+not influence the extended substitution syntax described below.
+.P
+PCRE2_SUBSTITUTE_EXTENDED causes extra processing to be applied to the
+replacement string. Without this option, only the dollar character is special,
+and only the group insertion forms listed above are valid. When
+PCRE2_SUBSTITUTE_EXTENDED is set, two things change:
+.P
+Firstly, backslash in a replacement string is interpreted as an escape
+character. The usual forms such as \en or \ex{ddd} can be used to specify
+particular character codes, and backslash followed by any non-alphanumeric
+character quotes that character. Extended quoting can be coded using \eQ...\eE,
+exactly as in pattern strings.
+.P
+There are also four escape sequences for forcing the case of inserted letters.
+The insertion mechanism has three states: no case forcing, force upper case,
+and force lower case. The escape sequences change the current state: \eU and
+\eL change to upper or lower case forcing, respectively, and \eE (when not
+terminating a \eQ quoted sequence) reverts to no case forcing. The sequences
+\eu and \el force the next character (if it is a letter) to upper or lower
+case, respectively, and then the state automatically reverts to no case
+forcing. Case forcing applies to all inserted characters, including those from
+captured groups and letters within \eQ...\eE quoted sequences.
+.P
+Note that case forcing sequences such as \eU...\eE do not nest. For example,
+the result of processing "\eUaa\eLBB\eEcc\eE" is "AAbbcc"; the final \eE has no
+effect.
+.P
+The second effect of setting PCRE2_SUBSTITUTE_EXTENDED is to add more
+flexibility to group substitution. The syntax is similar to that used by Bash:
+.sp
+ ${<n>:-<string>}
+ ${<n>:+<string1>:<string2>}
+.sp
+As before, <n> may be a group number or a name. The first form specifies a
+default value. If group <n> is set, its value is inserted; if not, <string> is
+expanded and the result inserted. The second form specifies strings that are
+expanded and inserted when group <n> is set or unset, respectively. The first
+form is just a convenient shorthand for
+.sp
+ ${<n>:+${<n>}:<string>}
+.sp
+Backslash can be used to escape colons and closing curly brackets in the
+replacement strings. A change of the case forcing state within a replacement
+string remains in force afterwards, as shown in this \fBpcre2test\fP example:
+.sp
+ /(some)?(body)/substitute_extended,replace=${1:+\eU:\eL}HeLLo
+ body
+ 1: hello
+ somebody
+ 1: HELLO
+.sp
+The PCRE2_SUBSTITUTE_UNSET_EMPTY option does not affect these extended
+substitutions. However, PCRE2_SUBSTITUTE_UNKNOWN_UNSET does cause unknown
+groups in the extended syntax forms to be treated as unset.
+.P
+If successful, \fBpcre2_substitute()\fP returns the number of replacements that
+were made. This may be zero if no matches were found, and is never greater than
+1 unless PCRE2_SUBSTITUTE_GLOBAL is set.
+.P
+In the event of an error, a negative error code is returned. Except for
+PCRE2_ERROR_NOMATCH (which is never returned), errors from \fBpcre2_match()\fP
+are passed straight back.
+.P
+PCRE2_ERROR_NOSUBSTRING is returned for a non-existent substring insertion,
+unless PCRE2_SUBSTITUTE_UNKNOWN_UNSET is set.
+.P
+PCRE2_ERROR_UNSET is returned for an unset substring insertion (including an
+unknown substring when PCRE2_SUBSTITUTE_UNKNOWN_UNSET is set) when the simple
+(non-extended) syntax is used and PCRE2_SUBSTITUTE_UNSET_EMPTY is not set.
+.P
+PCRE2_ERROR_NOMEMORY is returned if the output buffer is not big enough. If the
+PCRE2_SUBSTITUTE_OVERFLOW_LENGTH option is set, the size of buffer that is
+needed is returned via \fIoutlengthptr\fP. Note that this does not happen by
+default.
+.P
+PCRE2_ERROR_BADREPLACEMENT is used for miscellaneous syntax errors in the
+replacement string, with more particular errors being PCRE2_ERROR_BADREPESCAPE
+(invalid escape sequence), PCRE2_ERROR_REPMISSING_BRACE (closing curly bracket
+not found), PCRE2_BADSUBSTITUTION (syntax error in extended group
+substitution), and PCRE2_BADSUBPATTERN (the pattern match ended before it
+started, which can happen if \eK is used in an assertion).
+.P
+As for all PCRE2 errors, a text message that describes the error can be
+obtained by calling \fBpcre2_get_error_message()\fP.

+.P
+Normally, patterns with duplicate names are such that in any one match, only
+one of the named subpatterns participates. An example is shown in the
+.\" HREF
+\fBpcre2pattern\fP
+.\"
+documentation.
+.P
+When duplicates are present, \fBpcre2_substring_copy_byname()\fP and
+\fBpcre2_substring_get_byname()\fP return the first substring corresponding to

+returned. The \fBpcre2_substring_number_from_name()\fP function returns the
+error PCRE2_ERROR_NOUNIQUESUBSTRING when there are duplicate names.
+.P
+If you want to get full details of all captured substrings for a given name,
+you must use the \fBpcre2_substring_nametable_scan()\fP function. The first
+argument is the compiled pattern, and the second is the name. If the third and
+fourth arguments are NULL, the function returns a group number for a unique
+name, or PCRE2_ERROR_NOUNIQUESUBSTRING otherwise.
+.P
+When the third and fourth arguments are not NULL, they must be pointers to
+variables that are updated by the function. After it has run, they point to the
+first and last entries in the name-to-number table for the given name, and the
+function returns the length of each entry in code units. In both cases,
+PCRE2_ERROR_NOSUBSTRING is returned if there are no entries for the given name.

+.P
+The function \fBpcre2_dfa_match()\fP is called to match a subject string
+against a compiled pattern, using a matching algorithm that scans the subject
+string just once, and does not backtrack. This has different characteristics to
+the normal algorithm, and is not compatible with Perl. Some of the features of
+PCRE2 patterns are not supported. Nevertheless, there are times when this kind
+of matching can be useful. For a discussion of the two matching algorithms, and
+a list of features that \fBpcre2_dfa_match()\fP does not support, see the
+.\" HREF
+\fBpcre2matching\fP
+.\"
+documentation.
+.P
+The arguments for the \fBpcre2_dfa_match()\fP function are the same as for
+\fBpcre2_match()\fP, plus two extras. The ovector within the match data block
+is used in a different way, and this is described below. The other common
+arguments are used in the same way as for \fBpcre2_match()\fP, so their
+description is not repeated here.
+.P
+The two additional arguments provide workspace for the function. The workspace
+vector should contain at least 20 elements. It is used for keeping track of
+multiple paths through the pattern tree. More workspace is needed for patterns
+and subjects where there are a lot of potential matches.
+.P
+Here is an example of a simple call to \fBpcre2_dfa_match()\fP:
+.sp
+ int wspace[20];
+ pcre2_match_data *md = pcre2_match_data_create(4, NULL);
+ int rc = pcre2_dfa_match(
+ re, /* result of pcre2_compile() */
+ "some string", /* the subject string */
+ 11, /* the length of the subject string */
+ 0, /* start at offset 0 in the subject */
+ 0, /* default options */
+ match_data, /* the match data block */
+ NULL, /* a match context; NULL means use defaults */
+ wspace, /* working space vector */
+ 20); /* number of elements (NOT size in bytes) */
+.
+.SS "Option bits for \fBpcre_dfa_match()\fP"
+.rs
+.sp
+The unused bits of the \fIoptions\fP argument for \fBpcre2_dfa_match()\fP must
+be zero. The only bits that may be set are PCRE2_ANCHORED, PCRE2_NOTBOL,
+PCRE2_NOTEOL, PCRE2_NOTEMPTY, PCRE2_NOTEMPTY_ATSTART, PCRE2_NO_UTF_CHECK,
+PCRE2_PARTIAL_HARD, PCRE2_PARTIAL_SOFT, PCRE2_DFA_SHORTEST, and
+PCRE2_DFA_RESTART. All but the last four of these are exactly the same as for
+\fBpcre2_match()\fP, so their description is not repeated here.
+.sp
+ PCRE2_PARTIAL_HARD
+ PCRE2_PARTIAL_SOFT
+.sp
+These have the same general effect as they do for \fBpcre2_match()\fP, but the
+details are slightly different. When PCRE2_PARTIAL_HARD is set for
+\fBpcre2_dfa_match()\fP, it returns PCRE2_ERROR_PARTIAL if the end of the
+subject is reached and there is still at least one matching possibility that
+requires additional characters. This happens even if some complete matches have
+already been found. When PCRE2_PARTIAL_SOFT is set, the return code
+PCRE2_ERROR_NOMATCH is converted into PCRE2_ERROR_PARTIAL if the end of the
+subject is reached, there have been no complete matches, but there is still at
+least one matching possibility. The portion of the string that was inspected
+when the longest partial match was found is set as the first matching string in
+both cases. There is a more detailed discussion of partial and multi-segment
+matching, with examples, in the
+.\" HREF
+\fBpcre2partial\fP
+.\"
+documentation.
+.sp
+ PCRE2_DFA_SHORTEST
+.sp
+Setting the PCRE2_DFA_SHORTEST option causes the matching algorithm to stop as
+soon as it has found one match. Because of the way the alternative algorithm
+works, this is necessarily the shortest possible match at the first possible
+matching point in the subject string.
+.sp
+ PCRE2_DFA_RESTART
+.sp
+When \fBpcre2_dfa_match()\fP returns a partial match, it is possible to call it
+again, with additional subject characters, and have it continue with the same
+match. The PCRE2_DFA_RESTART option requests this action; when it is set, the
+\fIworkspace\fP and \fIwscount\fP options must reference the same vector as
+before because data about the match so far is left in them after a partial
+match. There is more discussion of this facility in the
+.\" HREF
+\fBpcre2partial\fP
+.\"
+documentation.
+.
+.
+.SS "Successful returns from \fBpcre2_dfa_match()\fP"
+.rs
+.sp
+When \fBpcre2_dfa_match()\fP succeeds, it may have matched more than one
+substring in the subject. Note, however, that all the matches from one run of
+the function start at the same point in the subject. The shorter matches are
+all initial substrings of the longer matches. For example, if the pattern
+.sp
+ <.*>
+.sp
+is matched against the string
+.sp
+ This is <something> <something else> <something further> no more
+.sp
+the three matched strings are
+.sp
+ <something> <something else> <something further>
+ <something> <something else>
+ <something>
+.sp
+On success, the yield of the function is a number greater than zero, which is
+the number of matched substrings. The offsets of the substrings are returned in
+the ovector, and can be extracted by number in the same way as for
+\fBpcre2_match()\fP, but the numbers bear no relation to any capturing groups
+that may exist in the pattern, because DFA matching does not support group
+capture.
+.P
+Calls to the convenience functions that extract substrings by name
+return the error PCRE2_ERROR_DFA_UFUNC (unsupported function) if used after a
+DFA match. The convenience functions that extract substrings by number never
+return PCRE2_ERROR_NOSUBSTRING, and the meanings of some other errors are
+slightly different:
+.sp
+ PCRE2_ERROR_UNAVAILABLE
+.sp
+The ovector is not big enough to include a slot for the given substring number.
+.sp
+ PCRE2_ERROR_UNSET
+.sp
+There is a slot in the ovector for this substring, but there were insufficient
+matches to fill it.
+.P
+The matched strings are stored in the ovector in reverse order of length; that
+is, the longest matching string is first. If there were too many matches to fit
+into the ovector, the yield of the function is zero, and the vector is filled
+with the longest matches.
+.P
+NOTE: PCRE2's "auto-possessification" optimization usually applies to character
+repeats at the end of a pattern (as well as internally). For example, the
+pattern "a\ed+" is compiled as if it were "a\ed++". For DFA matching, this
+means that only one possible match is found. If you really do want multiple
+matches in such cases, either use an ungreedy repeat auch as "a\ed+?" or set
+the PCRE2_NO_AUTO_POSSESS option when compiling.
+.
+.
+.SS "Error returns from \fBpcre2_dfa_match()\fP"

+.sp
+The \fBpcre2_dfa_match()\fP function returns a negative number when it fails.
+Many of the errors are the same as for \fBpcre2_match()\fP, as described
+.\" HTML <a href="#errorlist">

+above.
+.\"
+There are in addition the following errors that are specific to
+\fBpcre2_dfa_match()\fP:
+.sp
+ PCRE2_ERROR_DFA_UITEM
+.sp
+This return is given if \fBpcre2_dfa_match()\fP encounters an item in the
+pattern that it does not support, for instance, the use of \eC in a UTF mode or
+a back reference.
+.sp
+ PCRE2_ERROR_DFA_UCOND
+.sp
+This return is given if \fBpcre2_dfa_match()\fP encounters a condition item
+that uses a back reference for the condition, or a test for recursion in a
+specific group. These are not supported.
+.sp
+ PCRE2_ERROR_DFA_WSSIZE
+.sp
+This return is given if \fBpcre2_dfa_match()\fP runs out of space in the
+\fIworkspace\fP vector.
+.sp
+ PCRE2_ERROR_DFA_RECURSE
+.sp
+When a recursive subpattern is processed, the matching function calls itself
+recursively, using private memory for the ovector and \fIworkspace\fP. This
+error is given if the internal ovector is not large enough. This should be
+extremely rare, as a vector of size 1000 is used.
+.sp
+ PCRE2_ERROR_DFA_BADRESTART
+.sp
+When \fBpcre2_dfa_match()\fP is called with the \fBPCRE2_DFA_RESTART\fP option,
+some plausibility checks are made on the contents of the workspace, which
+should contain data about the previous partial match. If any of these checks
+fail, this error is given.

+.sp
+ ./configure --help
+.sp
+The following sections include descriptions of options whose names begin with
+--enable or --disable. These settings specify changes to the defaults for the
+\fBconfigure\fP command. Because of the way that \fBconfigure\fP works,
+--enable and --disable always come in pairs, so the complementary option always
+exists as well, but as it specifies the default, it is not described.
+.
+.
+.SH "BUILDING 8-BIT, 16-BIT AND 32-BIT LIBRARIES"
+.rs
+.sp
+By default, a library called \fBlibpcre2-8\fP is built, containing functions
+that take string arguments contained in vectors of bytes, interpreted either as
+single-byte characters, or UTF-8 strings. You can also build two other
+libraries, called \fBlibpcre2-16\fP and \fBlibpcre2-32\fP, which process
+strings that are contained in vectors of 16-bit and 32-bit code units,
+respectively. These can be interpreted either as single-unit characters or
+UTF-16/UTF-32 strings. To build these additional libraries, add one or both of
+the following to the \fBconfigure\fP command:
+.sp
+ --enable-pcre2-16
+ --enable-pcre2-32
+.sp
+If you do not want the 8-bit library, add
+.sp
+ --disable-pcre2-8
+.sp
+as well. At least one of the three libraries must be built. Note that the POSIX
+wrapper is for the 8-bit library only, and that \fBpcre2grep\fP is an 8-bit
+program. Neither of these are built if you select only the 16-bit or 32-bit
+libraries.
+.
+.
+.SH "BUILDING SHARED AND STATIC LIBRARIES"
+.rs
+.sp
+The Autotools PCRE2 building process uses \fBlibtool\fP to build both shared
+and static libraries by default. You can suppress an unwanted library by adding
+one of
+.sp
+ --disable-shared
+ --disable-static
+.sp
+to the \fBconfigure\fP command.
+.
+.
+.SH "UNICODE AND UTF SUPPORT"
+.rs
+.sp
+By default, PCRE2 is built with support for Unicode and UTF character strings.
+To build it without Unicode support, add
+.sp
+ --disable-unicode
+.sp
+to the \fBconfigure\fP command. This setting applies to all three libraries. It
+is not possible to build one library with Unicode support, and another without,
+in the same configuration.
+.P
+Of itself, Unicode support does not make PCRE2 treat strings as UTF-8, UTF-16
+or UTF-32. To do that, applications that use the library can set the PCRE2_UTF
+option when they call \fBpcre2_compile()\fP to compile a pattern.
+Alternatively, patterns may be started with (*UTF) unless the application has
+locked this out by setting PCRE2_NEVER_UTF.
+.P
+UTF support allows the libraries to process character code points up to
+0x10ffff in the strings that they handle. It also provides support for
+accessing the Unicode properties of such characters, using pattern escapes such
+as \eP, \ep, and \eX. Only the general category properties such as \fILu\fP and
+\fINd\fP are supported. Details are given in the
+.\" HREF
+\fBpcre2pattern\fP
+.\"
+documentation.
+.P
+Pattern escapes such as \ed and \ew do not by default make use of Unicode
+properties. The application can request that they do by setting the PCRE2_UCP
+option. Unless the application has set PCRE2_NEVER_UCP, a pattern may also
+request this by starting with (*UCP).
+.
+.
+.SH "DISABLING THE USE OF \eC"
+.rs
+.sp
+The \eC escape sequence, which matches a single code unit, even in a UTF mode,
+can cause unpredictable behaviour because it may leave the current matching
+point in the middle of a multi-code-unit character. The application can lock it
+out by setting the PCRE2_NEVER_BACKSLASH_C option when calling
+\fBpcre2_compile()\fP. There is also a build-time option
+.sp
+ --enable-never-backslash-C
+.sp
+(note the upper case C) which locks out the use of \eC entirely.
+.
+.
+.SH "JUST-IN-TIME COMPILER SUPPORT"
+.rs
+.sp
+Just-in-time compiler support is included in the build by specifying
+.sp
+ --enable-jit
+.sp
+This support is available only for certain hardware architectures. If this
+option is set for an unsupported architecture, a building error occurs.
+See the
+.\" HREF
+\fBpcre2jit\fP
+.\"
+documentation for a discussion of JIT usage. When JIT support is enabled,
+pcre2grep automatically makes use of it, unless you add
+.sp
+ --disable-pcre2grep-jit
+.sp
+to the "configure" command.
+.
+.
+.SH "NEWLINE RECOGNITION"
+.rs
+.sp
+By default, PCRE2 interprets the linefeed (LF) character as indicating the end
+of a line. This is the normal newline character on Unix-like systems. You can
+compile PCRE2 to use carriage return (CR) instead, by adding
+.sp
+ --enable-newline-is-cr
+.sp
+to the \fBconfigure\fP command. There is also an --enable-newline-is-lf option,
+which explicitly specifies linefeed as the newline character.
+.P
+Alternatively, you can specify that line endings are to be indicated by the
+two-character sequence CRLF (CR immediately followed by LF). If you want this,
+add
+.sp
+ --enable-newline-is-crlf
+.sp
+to the \fBconfigure\fP command. There is a fourth option, specified by
+.sp
+ --enable-newline-is-anycrlf
+.sp
+which causes PCRE2 to recognize any of the three sequences CR, LF, or CRLF as
+indicating a line ending. Finally, a fifth option, specified by
+.sp
+ --enable-newline-is-any
+.sp
+causes PCRE2 to recognize any Unicode newline sequence. The Unicode newline
+sequences are the three just mentioned, plus the single characters VT (vertical
+tab, U+000B), FF (form feed, U+000C), NEL (next line, U+0085), LS (line
+separator, U+2028), and PS (paragraph separator, U+2029).
+.P
+Whatever default line ending convention is selected when PCRE2 is built can be
+overridden by applications that use the library. At build time it is
+conventional to use the standard for your operating system.
+.
+.
+.SH "WHAT \eR MATCHES"
+.rs
+.sp
+By default, the sequence \eR in a pattern matches any Unicode newline sequence,
+independently of what has been selected as the line ending sequence. If you
+specify
+.sp
+ --enable-bsr-anycrlf
+.sp
+the default is changed so that \eR matches only CR, LF, or CRLF. Whatever is
+selected when PCRE2 is built can be overridden by applications that use the
+called.
+.
+.
+.SH "HANDLING VERY LARGE PATTERNS"
+.rs
+.sp
+Within a compiled pattern, offset values are used to point from one part to
+another (for example, from an opening parenthesis to an alternation
+metacharacter). By default, in the 8-bit and 16-bit libraries, two-byte values
+are used for these offsets, leading to a maximum size for a compiled pattern of
+around 64K code units. This is sufficient to handle all but the most gigantic
+patterns. Nevertheless, some people do want to process truly enormous patterns,
+so it is possible to compile PCRE2 to use three-byte or four-byte offsets by
+adding a setting such as
+.sp
+ --with-link-size=3
+.sp
+to the \fBconfigure\fP command. The value given must be 2, 3, or 4. For the
+16-bit library, a value of 3 is rounded up to 4. In these libraries, using
+longer offsets slows down the operation of PCRE2 because it has to load
+additional data when handling them. For the 32-bit library the value is always
+4 and cannot be overridden; the value of --with-link-size is ignored.
+.
+.
+.SH "AVOIDING EXCESSIVE STACK USAGE"
+.rs
+.sp
+When matching with the \fBpcre2_match()\fP function, PCRE2 implements
+backtracking by making recursive calls to an internal function called
+\fBmatch()\fP. In environments where the size of the stack is limited, this can
+severely limit PCRE2's operation. (The Unix environment does not usually suffer
+from this problem, but it may sometimes be necessary to increase the maximum
+stack size. There is a discussion in the
+.\" HREF
+\fBpcre2stack\fP
+.\"
+documentation.) An alternative approach to recursion that uses memory from the
+heap to remember data, instead of using recursive function calls, has been
+implemented to work round the problem of limited stack size. If you want to
+build a version of PCRE2 that works this way, add
+.sp
+ --disable-stack-for-recursion
+.sp
+to the \fBconfigure\fP command. By default, the system functions \fBmalloc()\fP
+and \fBfree()\fP are called to manage the heap memory that is required, but
+custom memory management functions can be called instead. PCRE2 runs noticeably
+more slowly when built in this way. This option affects only the
+\fBpcre2_match()\fP function; it is not relevant for \fBpcre2_dfa_match()\fP.
+.
+.
+.SH "LIMITING PCRE2 RESOURCE USAGE"
+.rs
+.sp
+Internally, PCRE2 has a function called \fBmatch()\fP, which it calls
+repeatedly (sometimes recursively) when matching a pattern with the
+\fBpcre2_match()\fP function. By controlling the maximum number of times this
+function may be called during a single matching operation, a limit can be
+placed on the resources used by a single call to \fBpcre2_match()\fP. The limit
+can be changed at run time, as described in the
+.\" HREF
+\fBpcre2api\fP
+.\"
+documentation. The default is 10 million, but this can be changed by adding a
+setting such as
+.sp
+ --with-match-limit=500000
+.sp
+to the \fBconfigure\fP command. This setting has no effect on the
+\fBpcre2_dfa_match()\fP matching function.
+.P
+In some environments it is desirable to limit the depth of recursive calls of
+\fBmatch()\fP more strictly than the total number of calls, in order to
+restrict the maximum amount of stack (or heap, if --disable-stack-for-recursion
+is specified) that is used. A second limit controls this; it defaults to the
+value that is set for --with-match-limit, which imposes no additional
+constraints. However, you can set a lower limit by adding, for example,
+.sp
+ --with-match-limit-recursion=10000
+.sp
+to the \fBconfigure\fP command. This value can also be overridden at run time.
+.
+.
+.SH "CREATING CHARACTER TABLES AT BUILD TIME"
+.rs
+.sp
+PCRE2 uses fixed tables for processing characters whose code points are less
+than 256. By default, PCRE2 is built with a set of tables that are distributed
+in the file \fIsrc/pcre2_chartables.c.dist\fP. These tables are for ASCII codes
+only. If you add
+.sp
+ --enable-rebuild-chartables
+.sp
+to the \fBconfigure\fP command, the distributed tables are no longer used.
+Instead, a program called \fBdftables\fP is compiled and run. This outputs the
+source for new set of tables, created in the default locale of your C run-time
+system. (This method of replacing the tables does not work if you are cross
+compiling, because \fBdftables\fP is run on the local host. If you need to
+create alternative tables when cross compiling, you will have to do so "by
+hand".)
+.
+.
+.SH "USING EBCDIC CODE"
+.rs
+.sp
+PCRE2 assumes by default that it will run in an environment where the character
+code is ASCII or Unicode, which is a superset of ASCII. This is the case for
+most computer operating systems. PCRE2 can, however, be compiled to run in an
+8-bit EBCDIC environment by adding
+.sp
+ --enable-ebcdic --disable-unicode
+.sp
+to the \fBconfigure\fP command. This setting implies
+--enable-rebuild-chartables. You should only use it if you know that you are in
+an EBCDIC environment (for example, an IBM mainframe operating system).
+.P
+It is not possible to support both EBCDIC and UTF-8 codes in the same version
+of the library. Consequently, --enable-unicode and --enable-ebcdic are mutually
+exclusive.
+.P
+The EBCDIC character that corresponds to an ASCII LF is assumed to have the
+value 0x15 by default. However, in some EBCDIC environments, 0x25 is used. In
+such an environment you should use
+.sp
+ --enable-ebcdic-nl25
+.sp
+as well as, or instead of, --enable-ebcdic. The EBCDIC character for CR has the
+same value as in ASCII, namely, 0x0d. Whichever of 0x15 and 0x25 is \fInot\fP
+chosen as LF is made to correspond to the Unicode NEL character (which, in
+Unicode, is 0x85).
+.P
+The options that select newline behaviour, such as --enable-newline-is-cr,
+and equivalent run-time options, refer to these character values in an EBCDIC
+environment.
+.
+.
+.SH "PCRE2GREP OPTIONS FOR COMPRESSED FILE SUPPORT"
+.rs
+.sp
+By default, \fBpcre2grep\fP reads all files as plain text. You can build it so
+that it recognizes files whose names end in \fB.gz\fP or \fB.bz2\fP, and reads
+them with \fBlibz\fP or \fBlibbz2\fP, respectively, by adding one or both of
+.sp
+ --enable-pcre2grep-libz
+ --enable-pcre2grep-libbz2
+.sp
+to the \fBconfigure\fP command. These options naturally require that the
+relevant libraries are installed on your system. Configuration will fail if
+they are not.
+.
+.
+.SH "PCRE2GREP BUFFER SIZE"
+.rs
+.sp
+\fBpcre2grep\fP uses an internal buffer to hold a "window" on the file it is
+scanning, in order to be able to output "before" and "after" lines when it
+finds a match. The size of the buffer is controlled by a parameter whose
+default value is 20K. The buffer itself is three times this size, but because
+of the way it is used for holding "before" lines, the longest line that is
+guaranteed to be processable is the parameter size. You can change the default
+parameter value by adding, for example,
+.sp
+ --with-pcre2grep-bufsize=50K
+.sp
+to the \fBconfigure\fP command. The caller of \fPpcre2grep\fP can override this
+value by using --buffer-size on the command line..
+.
+.
+.SH "PCRE2TEST OPTION FOR LIBREADLINE SUPPORT"
+.rs
+.sp
+If you add one of
+.sp
+ --enable-pcre2test-libreadline
+ --enable-pcre2test-libedit
+.sp
+to the \fBconfigure\fP command, \fBpcre2test\fP is linked with the
+\fBlibreadline\fP or\fBlibedit\fP library, respectively, and when its input is
+from a terminal, it reads it using the \fBreadline()\fP function. This provides
+line-editing and history facilities. Note that \fBlibreadline\fP is
+GPL-licensed, so if you distribute a binary of \fBpcre2test\fP linked in this
+way, there may be licensing issues. These can be avoided by linking instead
+with \fBlibedit\fP, which has a BSD licence.
+.P
+Setting --enable-pcre2test-libreadline causes the \fB-lreadline\fP option to be
+added to the \fBpcre2test\fP build. In many operating environments with a
+sytem-installed readline library this is sufficient. However, in some
+environments (e.g. if an unmodified distribution version of readline is in
+use), some extra configuration may be necessary. The INSTALL file for
+\fBlibreadline\fP says this:
+.sp
+ "Readline uses the termcap functions, but does not link with
+ the termcap or curses library itself, allowing applications
+ which link with readline the to choose an appropriate library."
+.sp
+If your environment has not been set up so that an appropriate library is
+automatically included, you may need to add something like
+.sp
+ LIBS="-ncurses"
+.sp
+immediately before the \fBconfigure\fP command.
+.
+.
+.SH "INCLUDING DEBUGGING CODE"
+.rs
+.sp
+If you add
+.sp
+ --enable-debug
+.sp
+to the \fBconfigure\fP command, additional debugging code is included in the
+build. This feature is intended for use by the PCRE2 maintainers.
+.
+.
+.SH "DEBUGGING WITH VALGRIND SUPPORT"
+.rs
+.sp
+If you add
+.sp
+ --enable-valgrind
+.sp
+to the \fBconfigure\fP command, PCRE2 will use valgrind annotations to mark
+certain memory regions as unaddressable. This allows it to detect invalid
+memory accesses, and is mostly useful for debugging PCRE2 itself.
+.
+.
+.SH "CODE COVERAGE REPORTING"
+.rs
+.sp
+If your C compiler is gcc, you can build a version of PCRE2 that can generate a
+code coverage report for its test suite. To enable this, you must install
+\fBlcov\fP version 1.6 or above. Then specify
+.sp
+ --enable-coverage
+.sp
+to the \fBconfigure\fP command and build PCRE2 in the usual way.
+.P
+Note that using \fBccache\fP (a caching C compiler) is incompatible with code
+coverage reporting. If you have configured \fBccache\fP to run automatically
+on your system, you must set the environment variable
+.sp
+ CCACHE_DISABLE=1
+.sp
+before running \fBmake\fP to build PCRE2, so that \fBccache\fP is not used.
+.P
+When --enable-coverage is used, the following addition targets are added to the
+\fIMakefile\fP:
+.sp
+ make coverage
+.sp
+This creates a fresh coverage report for the PCRE2 test suite. It is equivalent
+to running "make coverage-reset", "make coverage-baseline", "make check", and
+then "make coverage-report".
+.sp
+ make coverage-reset
+.sp
+This zeroes the coverage counters, but does nothing else.
+.sp
+ make coverage-baseline
+.sp
+This captures baseline coverage information.
+.sp
+ make coverage-report
+.sp
+This creates the coverage report.
+.sp
+ make coverage-clean-report
+.sp
+This removes the generated coverage report without cleaning the coverage data
+itself.
+.sp
+ make coverage-clean-data
+.sp
+This removes the captured coverage data without removing the coverage files
+created at compile time (*.gcno).
+.sp
+ make coverage-clean
+.sp
+This cleans all coverage data including the generated coverage report. For more
+information about code coverage, see the \fBgcov\fP and \fBlcov\fP
+documentation.

+.fi
+.
+.SH DESCRIPTION
+.rs
+.sp
+PCRE2 provides a feature called "callout", which is a means of temporarily
+passing control to the caller of PCRE2 in the middle of pattern matching. The
+caller of PCRE2 provides an external function by putting its entry point in
+a match context (see \fBpcre2_set_callout()\fP in the
+.\" HREF
+\fBpcre2api\fP
+.\"
+documentation).
+.P
+Within a regular expression, (?C<arg>) indicates a point at which the external
+function is to be called. Different callout points can be identified by putting
+a number less than 256 after the letter C. The default value is zero.
+Alternatively, the argument may be a delimited string. The starting delimiter
+must be one of ` ' " ^ % # $ { and the ending delimiter is the same as the
+start, except for {, where the ending delimiter is }. If the ending delimiter
+is needed within the string, it must be doubled. For example, this pattern has
+two callout points:
+.sp
+ (?C1)abc(?C"some ""arbitrary"" text")def
+.sp
+If the PCRE2_AUTO_CALLOUT option bit is set when a pattern is compiled, PCRE2
+automatically inserts callouts, all with number 255, before each item in the
+pattern. For example, if PCRE2_AUTO_CALLOUT is used with the pattern
+.sp
+ A(\ed{2}|--)
+.sp
+it is processed as if it were
+.sp
+(?C255)A(?C255)((?C255)\ed{2}(?C255)|(?C255)-(?C255)-(?C255))(?C255)
+.sp
+Notice that there is a callout before and after each parenthesis and
+alternation bar. If the pattern contains a conditional group whose condition is
+an assertion, an automatic callout is inserted immediately before the
+condition. Such a callout may also be inserted explicitly, for example:
+.sp
+ (?(?C9)(?=a)ab|de) (?(?C%text%)(?!=d)ab|de)
+.sp
+This applies only to assertion conditions (because they are themselves
+independent groups).
+.P
+Callouts can be useful for tracking the progress of pattern matching. The
+.\" HREF
+\fBpcre2test\fP
+.\"
+program has a pattern qualifier (/auto_callout) that sets automatic callouts.
+When any callouts are present, the output from \fBpcre2test\fP indicates how
+the pattern is being matched. This is useful information when you are trying to
+optimize the performance of a particular pattern.
+.
+.
+.SH "MISSING CALLOUTS"
+.rs
+.sp
+You should be aware that, because of optimizations in the way PCRE2 compiles
+and matches patterns, callouts sometimes do not happen exactly as you might
+expect.
+.
+.
+.SS "Auto-possessification"
+.rs
+.sp
+At compile time, PCRE2 "auto-possessifies" repeated items when it knows that
+what follows cannot be part of the repeat. For example, a+[bc] is compiled as
+if it were a++[bc]. The \fBpcre2test\fP output when this pattern is compiled
+with PCRE2_ANCHORED and PCRE2_AUTO_CALLOUT and then applied to the string
+"aaaa" is:
+.sp
+ --->aaaa
+ +0 ^ a+
+ +2 ^ ^ [bc]
+ No match
+.sp
+This indicates that when matching [bc] fails, there is no backtracking into a+
+and therefore the callouts that would be taken for the backtracks do not occur.
+You can disable the auto-possessify feature by passing PCRE2_NO_AUTO_POSSESS to
+\fBpcre2_compile()\fP, or starting the pattern with (*NO_AUTO_POSSESS). In this
+case, the output changes to this:
+.sp
+ --->aaaa
+ +0 ^ a+
+ +2 ^ ^ [bc]
+ +2 ^ ^ [bc]
+ +2 ^ ^ [bc]
+ +2 ^^ [bc]
+ No match
+.sp
+This time, when matching [bc] fails, the matcher backtracks into a+ and tries
+again, repeatedly, until a+ itself fails.
+.
+.
+.SS "Automatic .* anchoring"
+.rs
+.sp
+By default, an optimization is applied when .* is the first significant item in
+a pattern. If PCRE2_DOTALL is set, so that the dot can match any character, the
+pattern is automatically anchored. If PCRE2_DOTALL is not set, a match can
+start only after an internal newline or at the beginning of the subject, and
+\fBpcre2_compile()\fP remembers this. This optimization is disabled, however,
+if .* is in an atomic group or if there is a back reference to the capturing
+group in which it appears. It is also disabled if the pattern contains (*PRUNE)
+or (*SKIP). However, the presence of callouts does not affect it.
+.P
+For example, if the pattern .*\ed is compiled with PCRE2_AUTO_CALLOUT and
+applied to the string "aa", the \fBpcre2test\fP output is:
+.sp
+ --->aa
+ +0 ^ .*
+ +2 ^ ^ \ed
+ +2 ^^ \ed
+ +2 ^ \ed
+ No match
+.sp
+This shows that all match attempts start at the beginning of the subject. In
+other words, the pattern is anchored. You can disable this optimization by
+passing PCRE2_NO_DOTSTAR_ANCHOR to \fBpcre2_compile()\fP, or starting the
+pattern with (*NO_DOTSTAR_ANCHOR). In this case, the output changes to:
+.sp
+ --->aa
+ +0 ^ .*
+ +2 ^ ^ \ed
+ +2 ^^ \ed
+ +2 ^ \ed
+ +0 ^ .*
+ +2 ^^ \ed
+ +2 ^ \ed
+ No match
+.sp
+This shows more match attempts, starting at the second subject character.
+Another optimization, described in the next section, means that there is no
+subsequent attempt to match with an empty subject.
+.P
+If a pattern has more than one top-level branch, automatic anchoring occurs if
+all branches are anchorable.
+.
+.
+.SS "Other optimizations"
+.rs
+.sp
+Other optimizations that provide fast "no match" results also affect callouts.
+For example, if the pattern is
+.sp
+ ab(?C4)cd
+.sp
+PCRE2 knows that any matching string must contain the letter "d". If the
+subject string is "abyz", the lack of "d" means that matching doesn't ever
+start, and the callout is never reached. However, with "abyd", though the
+result is still no match, the callout is obeyed.
+.P
+PCRE2 also knows the minimum length of a matching string, and will immediately
+give a "no match" return without actually running a match if the subject is not
+long enough, or, for unanchored patterns, if it has been scanned far enough.
+.P
+You can disable these optimizations by passing the PCRE2_NO_START_OPTIMIZE
+option to \fBpcre2_compile()\fP, or by starting the pattern with
+(*NO_START_OPT). This slows down the matching process, but does ensure that
+callouts such as the example above are obeyed.
+.
+.
+.\" HTML <a name="calloutinterface"></a>
+.SH "THE CALLOUT INTERFACE"
+.rs
+.sp
+During matching, when PCRE2 reaches a callout point, if an external function is
+set in the match context, it is called. This applies to both normal and DFA
+matching. The first argument to the callout function is a pointer to a
+\fBpcre2_callout\fP block. The second argument is the void * callout data that
+was supplied when the callout was set up by calling \fBpcre2_set_callout()\fP
+(see the
+.\" HREF
+\fBpcre2api\fP
+.\"
+documentation). The callout block structure contains the following fields:
+.sp
+ uint32_t \fIversion\fP;

+ PCRE2_SPTR \fIcallout_string\fP;
+.sp
+The \fIversion\fP field contains the version number of the block format. The
+current version is 1; the three callout string fields were added for this
+version. If you are writing an application that might use an earlier release of
+PCRE2, you should check the version number before accessing any of these
+fields. The version number will increase in future if more fields are added,
+but the intention is never to remove any of the existing fields.
+.
+.
+.SS "Fields for numerical callouts"
+.rs
+.sp
+For a numerical callout, \fIcallout_string\fP is NULL, and \fIcallout_number\fP
+contains the number of the callout, in the range 0-255. This is the number
+that follows (?C for manual callouts; it is 255 for automatically generated
+callouts.
+.
+.
+.SS "Fields for string callouts"
+.rs
+.sp
+For callouts with string arguments, \fIcallout_number\fP is always zero, and
+\fIcallout_string\fP points to the string that is contained within the compiled
+pattern. Its length is given by \fIcallout_string_length\fP. Duplicated ending
+delimiters that were present in the original pattern string have been turned
+into single characters, but there is no other processing of the callout string
+argument. An additional code unit containing binary zero is present after the
+string, but is not included in the length. The delimiter that was used to start
+the string is also stored within the pattern, immediately before the string
+itself. You can access this delimiter as \fIcallout_string\fP[-1] if you need
+it.
+.P
+The \fIcallout_string_offset\fP field is the code unit offset to the start of
+the callout argument string within the original pattern string. This is
+provided for the benefit of applications such as script languages that might
+need to report errors in the callout string within the pattern.
+.
+.
+.SS "Fields for all callouts"
+.rs
+.sp
+The remaining fields in the callout block are the same for both kinds of
+callout.
+.P
+The \fIoffset_vector\fP field is a pointer to the vector of capturing offsets
+(the "ovector") that was passed to the matching function in the match data
+block. When \fBpcre2_match()\fP is used, the contents can be inspected in
+order to extract substrings that have been matched so far, in the same way as
+for extracting substrings after a match has completed. For the DFA matching
+function, this field is not useful.
+.P
+The \fIsubject\fP and \fIsubject_length\fP fields contain copies of the values
+that were passed to the matching function.
+.P
+The \fIstart_match\fP field normally contains the offset within the subject at
+which the current match attempt started. However, if the escape sequence \eK
+has been encountered, this value is changed to reflect the modified starting
+point. If the pattern is not anchored, the callout function may be called
+several times from the same point in the pattern for different starting points
+in the subject.
+.P
+The \fIcurrent_position\fP field contains the offset within the subject of the
+current match pointer.
+.P
+When the \fBpcre2_match()\fP is used, the \fIcapture_top\fP field contains one
+more than the number of the highest numbered captured substring so far. If no
+substrings have been captured, the value of \fIcapture_top\fP is one. This is
+always the case when the DFA functions are used, because they do not support
+captured substrings.
+.P
+The \fIcapture_last\fP field contains the number of the most recently captured
+substring. However, when a recursion exits, the value reverts to what it was
+outside the recursion, as do the values of all captured substrings. If no
+substrings have been captured, the value of \fIcapture_last\fP is 0. This is
+always the case for the DFA matching functions.
+.P
+The \fIpattern_position\fP field contains the offset in the pattern string to
+the next item to be matched.
+.P
+The \fInext_item_length\fP field contains the length of the next item to be
+matched in the pattern string. When the callout immediately precedes an
+alternation bar, a closing parenthesis, or the end of the pattern, the length
+is zero. When the callout precedes an opening parenthesis, the length is that
+of the entire subpattern.
+.P
+The \fIpattern_position\fP and \fInext_item_length\fP fields are intended to
+help in distinguishing between different automatic callouts, which all have the
+same callout number. However, they are set for all callouts, and are used by
+\fBpcre2test\fP to show the next item to be matched when displaying callout
+information.
+.P
+In callouts from \fBpcre2_match()\fP the \fImark\fP field contains a pointer to
+the zero-terminated name of the most recently passed (*MARK), (*PRUNE), or
+(*THEN) item in the match, or NULL if no such items have been passed. Instances
+of (*PRUNE) or (*THEN) without a name do not obliterate a previous (*MARK). In
+callouts from the DFA matching function this field always contains NULL.
+.
+.
+.SH "RETURN VALUES FROM CALLOUTS"
+.rs
+.sp
+The external callout function returns an integer to PCRE2. If the value is
+zero, matching proceeds as normal. If the value is greater than zero, matching
+fails at the current point, but the testing of other matching possibilities
+goes ahead, just as if a lookahead assertion had failed. If the value is less
+than zero, the match is abandoned, and the matching function returns the
+negative value.
+.P
+Negative values should normally be chosen from the set of PCRE2_ERROR_xxx
+values. In particular, PCRE2_ERROR_NOMATCH forces a standard "no match"
+failure. The error number PCRE2_ERROR_CALLOUT is reserved for use by callout
+functions; it will never be used by PCRE2 itself.
+.
+.
+.SH "CALLOUT ENUMERATION"
+.rs
+.sp
+.nf
+.B int pcre2_callout_enumerate(const pcre2_code *\fIcode\fP,
+.B " int (*\fIcallback\fP)(pcre2_callout_enumerate_block *, void *),"
+.B " void *\fIuser_data\fP);"
+.fi
+.sp
+A script language that supports the use of string arguments in callouts might
+like to scan all the callouts in a pattern before running the match. This can
+be done by calling \fBpcre2_callout_enumerate()\fP. The first argument is a
+pointer to a compiled pattern, the second points to a callback function, and
+the third is arbitrary user data. The callback function is called for every
+callout in the pattern in the order in which they appear. Its first argument is
+a pointer to a callout enumeration block, and its second argument is the
+\fIuser_data\fP value that was passed to \fBpcre2_callout_enumerate()\fP. The
+data block contains the following fields:
+.sp
+ \fIversion\fP Block version number
+ \fIpattern_position\fP Offset to next item in pattern
+ \fInext_item_length\fP Length of next item in pattern
+ \fIcallout_number\fP Number for numbered callouts
+ \fIcallout_string_offset\fP Offset to string within pattern
+ \fIcallout_string_length\fP Length of callout string
+ \fIcallout_string\fP Points to callout string or is NULL
+.sp
+The version number is currently 0. It will increase if new fields are ever
+added to the block. The remaining fields are the same as their namesakes in the
+\fBpcre2_callout\fP block that is used for callouts during matching, as
+described
+.\" HTML <a href="#calloutinterface">
+.\" </a>
+above.
+.\"
+.P
+Note that the value of \fIpattern_position\fP is unique for each callout.
+However, if a callout occurs inside a group that is quantified with a non-zero
+minimum or a fixed maximum, the group is replicated inside the compiled
+pattern. For example, a pattern such as /(a){2}/ is compiled as if it were
+/(a)(a)/. This means that the callout will be enumerated more than once, but
+with the same value for \fIpattern_position\fP in each case.
+.P
+The callback function should normally return zero. If it returns a non-zero
+value, scanning the pattern stops, and that value is returned from
+\fBpcre2_callout_enumerate()\fP.

+.TH PCRE2COMPAT 3 "15 March 2015" "PCRE2 10.20"
+.SH NAME
+PCRE2 - Perl-compatible regular expressions (revised API)
+.SH "DIFFERENCES BETWEEN PCRE2 AND PERL"
+.rs
+.sp
+This document describes the differences in the ways that PCRE2 and Perl handle
+regular expressions. The differences described here are with respect to Perl
+versions 5.10 and above.
+.P
+1. PCRE2 has only a subset of Perl's Unicode support. Details of what it does
+have are given in the
+.\" HREF
+\fBpcre2unicode\fP
+.\"
+page.
+.P
+2. PCRE2 allows repeat quantifiers only on parenthesized assertions, but they
+do not mean what you might think. For example, (?!a){3} does not assert that
+the next three characters are not "a". It just asserts that the next character
+is not "a" three times (in principle: PCRE2 optimizes this to run the assertion
+just once). Perl allows repeat quantifiers on other assertions such as \eb, but
+these do not seem to have any use.
+.P
+3. Capturing subpatterns that occur inside negative lookahead assertions are
+counted, but their entries in the offsets vector are never set. Perl sometimes
+(but not always) sets its numerical variables from inside negative assertions.
+.P
+4. The following Perl escape sequences are not supported: \el, \eu, \eL,
+\eU, and \eN when followed by a character name or Unicode value. (\eN on its
+own, matching a non-newline character, is supported.) In fact these are
+implemented by Perl's general string-handling and are not part of its pattern
+matching engine. If any of these are encountered by PCRE2, an error is
+generated by default. However, if the PCRE2_ALT_BSUX option is set,
+\eU and \eu are interpreted as ECMAScript interprets them.
+.P
+5. The Perl escape sequences \ep, \eP, and \eX are supported only if PCRE2 is
+built with Unicode support. The properties that can be tested with \ep and \eP
+are limited to the general category properties such as Lu and Nd, script names
+such as Greek or Han, and the derived properties Any and L&. PCRE2 does support
+the Cs (surrogate) property, which Perl does not; the Perl documentation says
+"Because Perl hides the need for the user to understand the internal
+representation of Unicode characters, there is no need to implement the
+somewhat messy concept of surrogates."
+.P
+6. PCRE2 does support the \eQ...\eE escape for quoting substrings. Characters
+in between are treated as literals. This is slightly different from Perl in
+that $ and @ are also handled as literals inside the quotes. In Perl, they
+cause variable interpolation (but of course PCRE2 does not have variables).
+Note the following examples:
+.sp
+ Pattern PCRE2 matches Perl matches
+.sp
+.\" JOIN
+ \eQabc$xyz\eE abc$xyz abc followed by the
+ contents of $xyz
+ \eQabc\e$xyz\eE abc\e$xyz abc\e$xyz
+ \eQabc\eE\e$\eQxyz\eE abc$xyz abc$xyz
+.sp
+The \eQ...\eE sequence is recognized both inside and outside character classes.
+.P
+7. Fairly obviously, PCRE2 does not support the (?{code}) and (??{code})
+constructions. However, there is support for recursive patterns. This is not
+available in Perl 5.8, but it is in Perl 5.10. Also, the PCRE2 "callout"
+feature allows an external function to be called during pattern matching. See
+the
+.\" HREF
+\fBpcre2callout\fP
+.\"
+documentation for details.
+.P
+8. Subroutine calls (whether recursive or not) are treated as atomic groups.
+Atomic recursion is like Python, but unlike Perl. Captured values that are set
+outside a subroutine call can be referenced from inside in PCRE2, but not in
+Perl. There is a discussion that explains these differences in more detail in
+the
+.\" HTML <a href="pcre2pattern.html#recursiondifference">
+.\" </a>
+section on recursion differences from Perl
+.\"
+in the
+.\" HREF
+\fBpcre2pattern\fP
+.\"
+page.
+.P
+9. If any of the backtracking control verbs are used in a subpattern that is
+called as a subroutine (whether or not recursively), their effect is confined
+to that subpattern; it does not extend to the surrounding pattern. This is not
+always the case in Perl. In particular, if (*THEN) is present in a group that
+is called as a subroutine, its action is limited to that group, even if the
+group does not contain any | characters. Note that such subpatterns are
+processed as anchored at the point where they are tested.
+.P
+10. If a pattern contains more than one backtracking control verb, the first
+one that is backtracked onto acts. For example, in the pattern
+A(*COMMIT)B(*PRUNE)C a failure in B triggers (*COMMIT), but a failure in C
+triggers (*PRUNE). Perl's behaviour is more complex; in many cases it is the
+same as PCRE2, but there are examples where it differs.
+.P
+11. Most backtracking verbs in assertions have their normal actions. They are
+not confined to the assertion.
+.P
+12. There are some differences that are concerned with the settings of captured
+strings when part of a pattern is repeated. For example, matching "aba" against
+the pattern /^(a(b)?)+$/ in Perl leaves $2 unset, but in PCRE2 it is set to
+"b".
+.P
+13. PCRE2's handling of duplicate subpattern numbers and duplicate subpattern
+names is not as general as Perl's. This is a consequence of the fact the PCRE2
+works internally just with numbers, using an external table to translate
+between numbers and names. In particular, a pattern such as (?|(?<a>A)|(?<b)B),
+where the two capturing parentheses have the same number but different names,
+is not supported, and causes an error at compile time. If it were allowed, it
+would not be possible to distinguish which parentheses matched, because both
+names map to capturing subpattern number 1. To avoid this confusing situation,
+an error is given at compile time.
+.P
+14. Perl recognizes comments in some places that PCRE2 does not, for example,
+between the ( and ? at the start of a subpattern. If the /x modifier is set,
+Perl allows white space between ( and ? (though current Perls warn that this is
+deprecated) but PCRE2 never does, even if the PCRE2_EXTENDED option is set.
+.P
+15. Perl, when in warning mode, gives warnings for character classes such as
+[A-\ed] or [a-[:digit:]]. It then treats the hyphens as literals. PCRE2 has no
+warning features, so it gives an error in these cases because they are almost
+certainly user mistakes.
+.P
+16. In PCRE2, the upper/lower case character properties Lu and Ll are not
+affected when case-independent matching is specified. For example, \ep{Lu}
+always matches an upper case letter. I think Perl has changed in this respect;
+in the release at the time of writing (5.16), \ep{Lu} and \ep{Ll} match all
+letters, regardless of case, when case independence is specified.
+.P
+17. PCRE2 provides some extensions to the Perl regular expression facilities.
+Perl 5.10 includes new features that are not in earlier versions of Perl, some
+of which (such as named parentheses) have been in PCRE2 for some time. This
+list is with respect to Perl 5.10:
+.sp
+(a) Although lookbehind assertions in PCRE2 must match fixed length strings,
+each alternative branch of a lookbehind assertion can match a different length
+of string. Perl requires them all to have the same length.
+.sp
+(b) If PCRE2_DOLLAR_ENDONLY is set and PCRE2_MULTILINE is not set, the $
+meta-character matches only at the very end of the string.
+.sp
+(c) A backslash followed by a letter with no special meaning is faulted. (Perl
+can be made to issue a warning.)
+.sp
+(d) If PCRE2_UNGREEDY is set, the greediness of the repetition quantifiers is
+inverted, that is, by default they are not greedy, but if followed by a
+question mark they are.
+.sp
+(e) PCRE2_ANCHORED can be used at matching time to force a pattern to be tried
+only at the first matching position in the subject string.
+.sp
+(f) The PCRE2_NOTBOL, PCRE2_NOTEOL, PCRE2_NOTEMPTY, PCRE2_NOTEMPTY_ATSTART, and
+PCRE2_NO_AUTO_CAPTURE options have no Perl equivalents.
+.sp
+(g) The \eR escape sequence can be restricted to match only CR, LF, or CRLF
+by the PCRE2_BSR_ANYCRLF option.
+.sp
+(h) The callout facility is PCRE2-specific.
+.sp
+(i) The partial matching facility is PCRE2-specific.
+.sp
+(j) The alternative matching function (\fBpcre2_dfa_match()\fP matches in a
+different way and is not Perl-compatible.
+.sp
+(k) PCRE2 recognizes some special sequences such as (*CR) at the start of
+a pattern that set overall options that cannot be changed within the pattern.

+/*************************************************
+* PCRE2 DEMONSTRATION PROGRAM *
+*************************************************/
+
+/* This is a demonstration program to illustrate a straightforward way of
+calling the PCRE2 regular expression library from a C program. See the
+pcre2sample documentation for a short discussion ("man pcre2sample" if you have
+the PCRE2 man pages installed). PCRE2 is a revised API for the library, and is
+incompatible with the original PCRE API.
+
+There are actually three libraries, each supporting a different code unit
+width. This demonstration program uses the 8-bit library.
+
+In Unix-like environments, if PCRE2 is installed in your standard system
+libraries, you should be able to compile this program using this command:
+
+gcc -Wall pcre2demo.c -lpcre2-8 -o pcre2demo
+
+If PCRE2 is not installed in a standard place, it is likely to be installed
+with support for the pkg-config mechanism. If you have pkg-config, you can
+compile this program using this command:
+
+gcc -Wall pcre2demo.c `pkg-config --cflags --libs libpcre2-8` -o pcre2demo
+
+If you do not have pkg-config, you may have to use this:
+
+gcc -Wall pcre2demo.c -I/usr/local/include -L/usr/local/lib \e
+ -R/usr/local/lib -lpcre2-8 -o pcre2demo
+
+Replace "/usr/local/include" and "/usr/local/lib" with wherever the include and
+library files for PCRE2 are installed on your system. Only some operating
+systems (Solaris is one) use the -R option.
+
+Building under Windows:
+
+If you want to statically link this program against a non-dll .a file, you must
+define PCRE2_STATIC before including pcre2.h, so in this environment, uncomment
+the following line. */
+
+/* #define PCRE2_STATIC */

+/*************************************************************************
+* If the "-g" option was given on the command line, we want to continue *
+* to search for additional matches in the subject string, in a similar *
+* way to the /g option in Perl. This turns out to be trickier than you *
+* might think because of the possibility of matching an empty string. *
+* What happens is as follows: *
+* *
+* If the previous match was NOT for an empty string, we can just start *
+* the next match at the end of the previous one. *
+* *
+* If the previous match WAS for an empty string, we can't do that, as it *
+* would lead to an infinite loop. Instead, a call of pcre2_match() is *
+* made with the PCRE2_NOTEMPTY_ATSTART and PCRE2_ANCHORED flags set. The *
+* first of these tells PCRE2 that an empty string at the start of the *
+* subject is not a valid match; other possibilities must be tried. The *
+* second flag restricts PCRE2 to one match attempt at the initial string *
+* position. If this match succeeds, an alternative to the empty string *
+* match has been found, and we can print it and proceed round the loop, *
+* advancing by the length of whatever was found. If this match does not *
+* succeed, we still stay in the loop, advancing by just one character. *
+* In UTF-8 mode, which can be set by (*UTF) in the pattern, this may be *
+* more than one byte. *
+* *
+* However, there is a complication concerned with newlines. When the *
+* newline convention is such that CRLF is a valid newline, we must *
+* advance by two characters rather than one. The newline convention can *
+* be set in the regex by (*CR), etc.; if not, we must find the default. *

+.TH PCRE2GREP 1 "03 January 2015" "PCRE2 10.00"
+.SH NAME
+pcre2grep - a grep with Perl-compatible regular expressions.
+.SH SYNOPSIS
+.B pcre2grep [options] [long options] [pattern] [path1 path2 ...]
+.
+.SH DESCRIPTION
+.rs
+.sp
+\fBpcre2grep\fP searches files for character patterns, in the same way as other
+grep commands do, but it uses the PCRE2 regular expression library to support
+patterns that are compatible with the regular expressions of Perl 5. See
+.\" HREF
+\fBpcre2syntax\fP(3)
+.\"
+for a quick-reference summary of pattern syntax, or
+.\" HREF
+\fBpcre2pattern\fP(3)
+.\"
+for a full description of the syntax and semantics of the regular expressions
+that PCRE2 supports.
+.P
+Patterns, whether supplied on the command line or in a separate file, are given
+without delimiters. For example:
+.sp
+ pcre2grep Thursday /etc/motd
+.sp
+If you attempt to use delimiters (for example, by surrounding a pattern with
+slashes, as is common in Perl scripts), they are interpreted as part of the
+pattern. Quotes can of course be used to delimit patterns on the command line
+because they are interpreted by the shell, and indeed quotes are required if a
+pattern contains white space or shell metacharacters.
+.P
+The first argument that follows any option settings is treated as the single
+pattern to be matched when neither \fB-e\fP nor \fB-f\fP is present.
+Conversely, when one or both of these options are used to specify patterns, all
+arguments are treated as path names. At least one of \fB-e\fP, \fB-f\fP, or an
+argument pattern must be provided.
+.P
+If no files are specified, \fBpcre2grep\fP reads the standard input. The
+standard input can also be referenced by a name consisting of a single hyphen.
+For example:
+.sp
+ pcre2grep some-pattern file1 - file3
+.sp
+Input files are searched line by line. By default, each line that matches a
+pattern is copied to the standard output, and if there is more than one file,
+the file name is output at the start of each line, followed by a colon.
+However, there are options that can change how \fBpcre2grep\fP behaves. In
+particular, the \fB-M\fP option makes it possible to search for strings that
+span line boundaries. What defines a line boundary is controlled by the
+\fB-N\fP (\fB--newline\fP) option.
+.P
+The amount of memory used for buffering files that are being scanned is
+controlled by a parameter that can be set by the \fB--buffer-size\fP option.
+The default value for this parameter is specified when \fBpcre2grep\fP is
+built, with the default default being 20K. A block of memory three times this
+size is used (to allow for buffering "before" and "after" lines). An error
+occurs if a line overflows the buffer.
+.P
+Patterns can be no longer than 8K or BUFSIZ bytes, whichever is the greater.
+BUFSIZ is defined in \fB<stdio.h>\fP. When there is more than one pattern
+(specified by the use of \fB-e\fP and/or \fB-f\fP), each pattern is applied to
+each line in the order in which they are defined, except that all the \fB-e\fP
+patterns are tried before the \fB-f\fP patterns.
+.P
+By default, as soon as one pattern matches a line, no further patterns are
+considered. However, if \fB--colour\fP (or \fB--color\fP) is used to colour the
+matching substrings, or if \fB--only-matching\fP, \fB--file-offsets\fP, or
+\fB--line-offsets\fP is used to output only the part of the line that matched
+(either shown literally, or as an offset), scanning resumes immediately
+following the match, so that further matches on the same line can be found. If
+there are multiple patterns, they are all tried on the remainder of the line,
+but patterns that follow the one that matched are not tried on the earlier part
+of the line.
+.P
+This behaviour means that the order in which multiple patterns are specified
+can affect the output when one of the above options is used. This is no longer
+the same behaviour as GNU grep, which now manages to display earlier matches
+for later patterns (as long as there is no overlap).
+.P
+Patterns that can match an empty string are accepted, but empty string
+matches are never recognized. An example is the pattern "(super)?(man)?", in
+which all components are optional. This pattern finds all occurrences of both
+"super" and "man"; the output differs from matching with "super|man" when only
+the matching substrings are being shown.
+.P
+If the \fBLC_ALL\fP or \fBLC_CTYPE\fP environment variable is set,
+\fBpcre2grep\fP uses the value to set a locale when calling the PCRE2 library.
+The \fB--locale\fP option can be used to override this.
+.
+.
+.SH "SUPPORT FOR COMPRESSED FILES"
+.rs
+.sp
+It is possible to compile \fBpcre2grep\fP so that it uses \fBlibz\fP or
+\fBlibbz2\fP to read files whose names end in \fB.gz\fP or \fB.bz2\fP,
+respectively. You can find out whether your binary has support for one or both
+of these file types by running it with the \fB--help\fP option. If the
+appropriate support is not present, files are treated as plain text. The
+standard input is always so treated.
+.
+.
+.SH "BINARY FILES"
+.rs
+.sp
+By default, a file that contains a binary zero byte within the first 1024 bytes
+is identified as a binary file, and is processed specially. (GNU grep also
+identifies binary files in this manner.) See the \fB--binary-files\fP option
+for a means of changing the way binary files are handled.
+.
+.
+.SH OPTIONS
+.rs
+.sp
+The order in which some of the options appear can affect the output. For
+example, both the \fB-h\fP and \fB-l\fP options affect the printing of file
+names. Whichever comes later in the command line will be the one that takes
+effect. Similarly, except where noted below, if an option is given twice, the
+later setting is used. Numerical values for options may be followed by K or M,
+to signify multiplication by 1024 or 1024*1024 respectively.
+.TP 10
+\fB--\fP
+This terminates the list of options. It is useful if the next item on the
+command line starts with a hyphen but is not an option. This allows for the
+processing of patterns and file names that start with hyphens.
+.TP
+\fB-A\fP \fInumber\fP, \fB--after-context=\fP\fInumber\fP
+Output \fInumber\fP lines of context after each matching line. If file names
+and/or line numbers are being output, a hyphen separator is used instead of a
+colon for the context lines. A line containing "--" is output between each
+group of lines, unless they are in fact contiguous in the input file. The value
+of \fInumber\fP is expected to be relatively small. However, \fBpcre2grep\fP
+guarantees to have up to 8K of following text available for context output.
+.TP
+\fB-a\fP, \fB--text\fP
+Treat binary files as text. This is equivalent to
+\fB--binary-files\fP=\fItext\fP.
+.TP
+\fB-B\fP \fInumber\fP, \fB--before-context=\fP\fInumber\fP
+Output \fInumber\fP lines of context before each matching line. If file names
+and/or line numbers are being output, a hyphen separator is used instead of a
+colon for the context lines. A line containing "--" is output between each
+group of lines, unless they are in fact contiguous in the input file. The value
+of \fInumber\fP is expected to be relatively small. However, \fBpcre2grep\fP
+guarantees to have up to 8K of preceding text available for context output.
+.TP
+\fB--binary-files=\fP\fIword\fP
+Specify how binary files are to be processed. If the word is "binary" (the
+default), pattern matching is performed on binary files, but the only output is
+"Binary file <name> matches" when a match succeeds. If the word is "text",
+which is equivalent to the \fB-a\fP or \fB--text\fP option, binary files are
+processed in the same way as any other file. In this case, when a match
+succeeds, the output may be binary garbage, which can have nasty effects if
+sent to a terminal. If the word is "without-match", which is equivalent to the
+\fB-I\fP option, binary files are not processed at all; they are assumed not to
+be of interest and are skipped without causing any output or affecting the
+return code.
+.TP
+\fB--buffer-size=\fP\fInumber\fP
+Set the parameter that controls how much memory is used for buffering files
+that are being scanned.
+.TP
+\fB-C\fP \fInumber\fP, \fB--context=\fP\fInumber\fP
+Output \fInumber\fP lines of context both before and after each matching line.
+This is equivalent to setting both \fB-A\fP and \fB-B\fP to the same value.
+.TP
+\fB-c\fP, \fB--count\fP
+Do not output lines from the files that are being scanned; instead output the
+number of matches (or non-matches if \fB-v\fP is used) that would otherwise
+have caused lines to be shown. By default, this count is the same as the number
+of suppressed lines, but if the \fB-M\fP (multiline) option is used (without
+\fB-v\fP), there may be more suppressed lines than the number of matches.
+.sp
+If no lines are selected, the number zero is output. If several files are are
+being scanned, a count is output for each of them. However, if the
+\fB--files-with-matches\fP option is also used, only those files whose counts
+are greater than zero are listed. When \fB-c\fP is used, the \fB-A\fP,
+\fB-B\fP, and \fB-C\fP options are ignored.
+.TP
+\fB--colour\fP, \fB--color\fP
+If this option is given without any data, it is equivalent to "--colour=auto".
+If data is required, it must be given in the same shell item, separated by an
+equals sign.
+.TP
+\fB--colour=\fP\fIvalue\fP, \fB--color=\fP\fIvalue\fP
+This option specifies under what circumstances the parts of a line that matched
+a pattern should be coloured in the output. By default, the output is not
+coloured. The value (which is optional, see above) may be "never", "always", or
+"auto". In the latter case, colouring happens only if the standard output is
+connected to a terminal. More resources are used when colouring is enabled,
+because \fBpcre2grep\fP has to search for all possible matches in a line, not
+just one, in order to colour them all.
+.sp
+The colour that is used can be specified by setting the environment variable
+PCRE2GREP_COLOUR or PCRE2GREP_COLOR. The value of this variable should be a
+string of two numbers, separated by a semicolon. They are copied directly into
+the control string for setting colour on a terminal, so it is your
+responsibility to ensure that they make sense. If neither of the environment
+variables is set, the default is "1;31", which gives red.
+.TP
+\fB-D\fP \fIaction\fP, \fB--devices=\fP\fIaction\fP
+If an input path is not a regular file or a directory, "action" specifies how
+it is to be processed. Valid values are "read" (the default) or "skip"
+(silently skip the path).
+.TP
+\fB-d\fP \fIaction\fP, \fB--directories=\fP\fIaction\fP
+If an input path is a directory, "action" specifies how it is to be processed.
+Valid values are "read" (the default in non-Windows environments, for
+compatibility with GNU grep), "recurse" (equivalent to the \fB-r\fP option), or
+"skip" (silently skip the path, the default in Windows environments). In the
+"read" case, directories are read as if they were ordinary files. In some
+operating systems the effect of reading a directory like this is an immediate
+end-of-file; in others it may provoke an error.
+.TP
+\fB-e\fP \fIpattern\fP, \fB--regex=\fP\fIpattern\fP, \fB--regexp=\fP\fIpattern\fP
+Specify a pattern to be matched. This option can be used multiple times in
+order to specify several patterns. It can also be used as a way of specifying a
+single pattern that starts with a hyphen. When \fB-e\fP is used, no argument
+pattern is taken from the command line; all arguments are treated as file
+names. There is no limit to the number of patterns. They are applied to each
+line in the order in which they are defined until one matches.
+.sp
+If \fB-f\fP is used with \fB-e\fP, the command line patterns are matched first,
+followed by the patterns from the file(s), independent of the order in which
+these options are specified. Note that multiple use of \fB-e\fP is not the same
+as a single pattern with alternatives. For example, X|Y finds the first
+character in a line that is X or Y, whereas if the two patterns are given
+separately, with X first, \fBpcre2grep\fP finds X if it is present, even if it
+follows Y in the line. It finds Y only if there is no X in the line. This
+matters only if you are using \fB-o\fP or \fB--colo(u)r\fP to show the part(s)
+of the line that matched.
+.TP
+\fB--exclude\fP=\fIpattern\fP
+Files (but not directories) whose names match the pattern are skipped without
+being processed. This applies to all files, whether listed on the command line,
+obtained from \fB--file-list\fP, or by scanning a directory. The pattern is a
+PCRE2 regular expression, and is matched against the final component of the
+file name, not the entire path. The \fB-F\fP, \fB-w\fP, and \fB-x\fP options do
+not apply to this pattern. The option may be given any number of times in order
+to specify multiple patterns. If a file name matches both an \fB--include\fP
+and an \fB--exclude\fP pattern, it is excluded. There is no short form for this
+option.
+.TP
+\fB--exclude-from=\fP\fIfilename\fP
+Treat each non-empty line of the file as the data for an \fB--exclude\fP
+option. What constitutes a newline when reading the file is the operating
+system's default. The \fB--newline\fP option has no effect on this option. This
+option may be given more than once in order to specify a number of files to
+read.
+.TP
+\fB--exclude-dir\fP=\fIpattern\fP
+Directories whose names match the pattern are skipped without being processed,
+whatever the setting of the \fB--recursive\fP option. This applies to all
+directories, whether listed on the command line, obtained from
+\fB--file-list\fP, or by scanning a parent directory. The pattern is a PCRE2
+regular expression, and is matched against the final component of the directory
+name, not the entire path. The \fB-F\fP, \fB-w\fP, and \fB-x\fP options do not
+apply to this pattern. The option may be given any number of times in order to
+specify more than one pattern. If a directory matches both \fB--include-dir\fP
+and \fB--exclude-dir\fP, it is excluded. There is no short form for this
+option.
+.TP
+\fB-F\fP, \fB--fixed-strings\fP
+Interpret each data-matching pattern as a list of fixed strings, separated by
+newlines, instead of as a regular expression. What constitutes a newline for
+this purpose is controlled by the \fB--newline\fP option. The \fB-w\fP (match
+as a word) and \fB-x\fP (match whole line) options can be used with \fB-F\fP.
+They apply to each of the fixed strings. A line is selected if any of the fixed
+strings are found in it (subject to \fB-w\fP or \fB-x\fP, if present). This
+option applies only to the patterns that are matched against the contents of
+files; it does not apply to patterns specified by any of the \fB--include\fP or
+\fB--exclude\fP options.
+.TP
+\fB-f\fP \fIfilename\fP, \fB--file=\fP\fIfilename\fP
+Read patterns from the file, one per line, and match them against
+each line of input. What constitutes a newline when reading the file is the
+operating system's default. The \fB--newline\fP option has no effect on this
+option. Trailing white space is removed from each line, and blank lines are
+ignored. An empty file contains no patterns and therefore matches nothing. See
+also the comments about multiple patterns versus a single pattern with
+alternatives in the description of \fB-e\fP above.
+.sp
+If this option is given more than once, all the specified files are
+read. A data line is output if any of the patterns match it. A file name can
+be given as "-" to refer to the standard input. When \fB-f\fP is used, patterns
+specified on the command line using \fB-e\fP may also be present; they are
+tested before the file's patterns. However, no other pattern is taken from the
+command line; all arguments are treated as the names of paths to be searched.
+.TP
+\fB--file-list\fP=\fIfilename\fP
+Read a list of files and/or directories that are to be scanned from the given
+file, one per line. Trailing white space is removed from each line, and blank
+lines are ignored. These paths are processed before any that are listed on the
+command line. The file name can be given as "-" to refer to the standard input.
+If \fB--file\fP and \fB--file-list\fP are both specified as "-", patterns are
+read first. This is useful only when the standard input is a terminal, from
+which further lines (the list of files) can be read after an end-of-file
+indication. If this option is given more than once, all the specified files are
+read.
+.TP
+\fB--file-offsets\fP
+Instead of showing lines or parts of lines that match, show each match as an
+offset from the start of the file and a length, separated by a comma. In this
+mode, no context is shown. That is, the \fB-A\fP, \fB-B\fP, and \fB-C\fP
+options are ignored. If there is more than one match in a line, each of them is
+shown separately. This option is mutually exclusive with \fB--line-offsets\fP
+and \fB--only-matching\fP.
+.TP
+\fB-H\fP, \fB--with-filename\fP
+Force the inclusion of the file name at the start of output lines when
+searching a single file. By default, the file name is not shown in this case.
+For matching lines, the file name is followed by a colon; for context lines, a
+hyphen separator is used. If a line number is also being output, it follows the
+file name. When the \fB-M\fP option causes a pattern to match more than one
+line, only the first is preceded by the file name.
+.TP
+\fB-h\fP, \fB--no-filename\fP
+Suppress the output file names when searching multiple files. By default,
+file names are shown when multiple files are searched. For matching lines, the
+file name is followed by a colon; for context lines, a hyphen separator is used.
+If a line number is also being output, it follows the file name.
+.TP
+\fB--help\fP
+Output a help message, giving brief details of the command options and file
+type support, and then exit. Anything else on the command line is
+ignored.
+.TP
+\fB-I\fP
+Ignore binary files. This is equivalent to
+\fB--binary-files\fP=\fIwithout-match\fP.
+.TP
+\fB-i\fP, \fB--ignore-case\fP
+Ignore upper/lower case distinctions during comparisons.
+.TP
+\fB--include\fP=\fIpattern\fP
+If any \fB--include\fP patterns are specified, the only files that are
+processed are those that match one of the patterns (and do not match an
+\fB--exclude\fP pattern). This option does not affect directories, but it
+applies to all files, whether listed on the command line, obtained from
+\fB--file-list\fP, or by scanning a directory. The pattern is a PCRE2 regular
+expression, and is matched against the final component of the file name, not
+the entire path. The \fB-F\fP, \fB-w\fP, and \fB-x\fP options do not apply to
+this pattern. The option may be given any number of times. If a file name
+matches both an \fB--include\fP and an \fB--exclude\fP pattern, it is excluded.
+There is no short form for this option.
+.TP
+\fB--include-from=\fP\fIfilename\fP
+Treat each non-empty line of the file as the data for an \fB--include\fP
+option. What constitutes a newline for this purpose is the operating system's
+default. The \fB--newline\fP option has no effect on this option. This option
+may be given any number of times; all the files are read.
+.TP
+\fB--include-dir\fP=\fIpattern\fP
+If any \fB--include-dir\fP patterns are specified, the only directories that
+are processed are those that match one of the patterns (and do not match an
+\fB--exclude-dir\fP pattern). This applies to all directories, whether listed
+on the command line, obtained from \fB--file-list\fP, or by scanning a parent
+directory. The pattern is a PCRE2 regular expression, and is matched against
+the final component of the directory name, not the entire path. The \fB-F\fP,
+\fB-w\fP, and \fB-x\fP options do not apply to this pattern. The option may be
+given any number of times. If a directory matches both \fB--include-dir\fP and
+\fB--exclude-dir\fP, it is excluded. There is no short form for this option.
+.TP
+\fB-L\fP, \fB--files-without-match\fP
+Instead of outputting lines from the files, just output the names of the files
+that do not contain any lines that would have been output. Each file name is
+output once, on a separate line.
+.TP
+\fB-l\fP, \fB--files-with-matches\fP
+Instead of outputting lines from the files, just output the names of the files
+containing lines that would have been output. Each file name is output
+once, on a separate line. Searching normally stops as soon as a matching line
+is found in a file. However, if the \fB-c\fP (count) option is also used,
+matching continues in order to obtain the correct count, and those files that
+have at least one match are listed along with their counts. Using this option
+with \fB-c\fP is a way of suppressing the listing of files with no matches.
+.TP
+\fB--label\fP=\fIname\fP
+This option supplies a name to be used for the standard input when file names
+are being output. If not supplied, "(standard input)" is used. There is no
+short form for this option.
+.TP
+\fB--line-buffered\fP
+When this option is given, input is read and processed line by line, and the
+output is flushed after each write. By default, input is read in large chunks,
+unless \fBpcre2grep\fP can determine that it is reading from a terminal (which
+is currently possible only in Unix-like environments). Output to terminal is
+normally automatically flushed by the operating system. This option can be
+useful when the input or output is attached to a pipe and you do not want
+\fBpcre2grep\fP to buffer up large amounts of data. However, its use will
+affect performance, and the \fB-M\fP (multiline) option ceases to work.
+.TP
+\fB--line-offsets\fP
+Instead of showing lines or parts of lines that match, show each match as a
+line number, the offset from the start of the line, and a length. The line
+number is terminated by a colon (as usual; see the \fB-n\fP option), and the
+offset and length are separated by a comma. In this mode, no context is shown.
+That is, the \fB-A\fP, \fB-B\fP, and \fB-C\fP options are ignored. If there is
+more than one match in a line, each of them is shown separately. This option is
+mutually exclusive with \fB--file-offsets\fP and \fB--only-matching\fP.
+.TP
+\fB--locale\fP=\fIlocale-name\fP
+This option specifies a locale to be used for pattern matching. It overrides
+the value in the \fBLC_ALL\fP or \fBLC_CTYPE\fP environment variables. If no
+locale is specified, the PCRE2 library's default (usually the "C" locale) is
+used. There is no short form for this option.
+.TP
+\fB--match-limit\fP=\fInumber\fP
+Processing some regular expression patterns can require a very large amount of
+memory, leading in some cases to a program crash if not enough is available.
+Other patterns may take a very long time to search for all possible matching
+strings. The \fBpcre2_match()\fP function that is called by \fBpcre2grep\fP to
+do the matching has two parameters that can limit the resources that it uses.
+.sp
+The \fB--match-limit\fP option provides a means of limiting resource usage
+when processing patterns that are not going to match, but which have a very
+large number of possibilities in their search trees. The classic example is a
+pattern that uses nested unlimited repeats. Internally, PCRE2 uses a function
+called \fBmatch()\fP which it calls repeatedly (sometimes recursively). The
+limit set by \fB--match-limit\fP is imposed on the number of times this
+function is called during a match, which has the effect of limiting the amount
+of backtracking that can take place.
+.sp
+The \fB--recursion-limit\fP option is similar to \fB--match-limit\fP, but
+instead of limiting the total number of times that \fBmatch()\fP is called, it
+limits the depth of recursive calls, which in turn limits the amount of memory
+that can be used. The recursion depth is a smaller number than the total number
+of calls, because not all calls to \fBmatch()\fP are recursive. This limit is
+of use only if it is set smaller than \fB--match-limit\fP.
+.sp
+There are no short forms for these options. The default settings are specified
+when the PCRE2 library is compiled, with the default default being 10 million.
+.TP
+\fB-M\fP, \fB--multiline\fP
+Allow patterns to match more than one line. When this option is given, patterns
+may usefully contain literal newline characters and internal occurrences of ^
+and $ characters. The output for a successful match may consist of more than
+one line. The first is the line in which the match started, and the last is the
+line in which the match ended. If the matched string ends with a newline
+sequence the output ends at the end of that line.
+.sp
+When this option is set, the PCRE2 library is called in "multiline" mode.
+However, \fBpcre2grep\fP still processes the input line by line. The difference
+is that a matched string may extend past the end of a line and continue on
+one or more subsequent lines. The newline sequence must be matched as part of
+the pattern. For example, to find the phrase "regular expression" in a file
+where "regular" might be at the end of a line and "expression" at the start of
+the next line, you could use this command:
+.sp
+ pcre2grep -M 'regular\es+expression' <file>
+.sp
+The \es escape sequence matches any white space character, including newlines,
+and is followed by + so as to match trailing white space on the first line as
+well as possibly handling a two-character newline sequence.
+.sp
+There is a limit to the number of lines that can be matched, imposed by the way
+that \fBpcre2grep\fP buffers the input file as it scans it. However,
+\fBpcre2grep\fP ensures that at least 8K characters or the rest of the file
+(whichever is the shorter) are available for forward matching, and similarly
+the previous 8K characters (or all the previous characters, if fewer than 8K)
+are guaranteed to be available for lookbehind assertions. The \fB-M\fP option
+does not work when input is read line by line (see \fP--line-buffered\fP.)
+.TP
+\fB-N\fP \fInewline-type\fP, \fB--newline\fP=\fInewline-type\fP
+The PCRE2 library supports five different conventions for indicating
+the ends of lines. They are the single-character sequences CR (carriage return)
+and LF (linefeed), the two-character sequence CRLF, an "anycrlf" convention,
+which recognizes any of the preceding three types, and an "any" convention, in
+which any Unicode line ending sequence is assumed to end a line. The Unicode
+sequences are the three just mentioned, plus VT (vertical tab, U+000B), FF
+(form feed, U+000C), NEL (next line, U+0085), LS (line separator, U+2028), and
+PS (paragraph separator, U+2029).
+.sp
+When the PCRE2 library is built, a default line-ending sequence is specified.
+This is normally the standard sequence for the operating system. Unless
+otherwise specified by this option, \fBpcre2grep\fP uses the library's default.
+The possible values for this option are CR, LF, CRLF, ANYCRLF, or ANY. This
+makes it possible to use \fBpcre2grep\fP to scan files that have come from
+other environments without having to modify their line endings. If the data
+that is being scanned does not agree with the convention set by this option,
+\fBpcre2grep\fP may behave in strange ways. Note that this option does not
+apply to files specified by the \fB-f\fP, \fB--exclude-from\fP, or
+\fB--include-from\fP options, which are expected to use the operating system's
+standard newline sequence.
+.TP
+\fB-n\fP, \fB--line-number\fP
+Precede each output line by its line number in the file, followed by a colon
+for matching lines or a hyphen for context lines. If the file name is also
+being output, it precedes the line number. When the \fB-M\fP option causes a
+pattern to match more than one line, only the first is preceded by its line
+number. This option is forced if \fB--line-offsets\fP is used.
+.TP
+\fB--no-jit\fP
+If the PCRE2 library is built with support for just-in-time compiling (which
+speeds up matching), \fBpcre2grep\fP automatically makes use of this, unless it
+was explicitly disabled at build time. This option can be used to disable the
+use of JIT at run time. It is provided for testing and working round problems.
+It should never be needed in normal use.
+.TP
+\fB-o\fP, \fB--only-matching\fP
+Show only the part of the line that matched a pattern instead of the whole
+line. In this mode, no context is shown. That is, the \fB-A\fP, \fB-B\fP, and
+\fB-C\fP options are ignored. If there is more than one match in a line, each
+of them is shown separately. If \fB-o\fP is combined with \fB-v\fP (invert the
+sense of the match to find non-matching lines), no output is generated, but the
+return code is set appropriately. If the matched portion of the line is empty,
+nothing is output unless the file name or line number are being printed, in
+which case they are shown on an otherwise empty line. This option is mutually
+exclusive with \fB--file-offsets\fP and \fB--line-offsets\fP.
+.TP
+\fB-o\fP\fInumber\fP, \fB--only-matching\fP=\fInumber\fP
+Show only the part of the line that matched the capturing parentheses of the
+given number. Up to 32 capturing parentheses are supported, and -o0 is
+equivalent to \fB-o\fP without a number. Because these options can be given
+without an argument (see above), if an argument is present, it must be given in
+the same shell item, for example, -o3 or --only-matching=2. The comments given
+for the non-argument case above also apply to this case. If the specified
+capturing parentheses do not exist in the pattern, or were not set in the
+match, nothing is output unless the file name or line number are being output.
+.sp
+If this option is given multiple times, multiple substrings are output, in the
+order the options are given. For example, -o3 -o1 -o3 causes the substrings
+matched by capturing parentheses 3 and 1 and then 3 again to be output. By
+default, there is no separator (but see the next option).
+.TP
+\fB--om-separator\fP=\fItext\fP
+Specify a separating string for multiple occurrences of \fB-o\fP. The default
+is an empty string. Separating strings are never coloured.
+.TP
+\fB-q\fP, \fB--quiet\fP
+Work quietly, that is, display nothing except error messages. The exit
+status indicates whether or not any matches were found.
+.TP
+\fB-r\fP, \fB--recursive\fP
+If any given path is a directory, recursively scan the files it contains,
+taking note of any \fB--include\fP and \fB--exclude\fP settings. By default, a
+directory is read as a normal file; in some operating systems this gives an
+immediate end-of-file. This option is a shorthand for setting the \fB-d\fP
+option to "recurse".
+.TP
+\fB--recursion-limit\fP=\fInumber\fP
+See \fB--match-limit\fP above.
+.TP
+\fB-s\fP, \fB--no-messages\fP
+Suppress error messages about non-existent or unreadable files. Such files are
+quietly skipped. However, the return code is still 2, even if matches were
+found in other files.
+.TP
+\fB-u\fP, \fB--utf-8\fP
+Operate in UTF-8 mode. This option is available only if PCRE2 has been compiled
+with UTF-8 support. All patterns (including those for any \fB--exclude\fP and
+\fB--include\fP options) and all subject lines that are scanned must be valid
+strings of UTF-8 characters.
+.TP
+\fB-V\fP, \fB--version\fP
+Write the version numbers of \fBpcre2grep\fP and the PCRE2 library to the
+standard output and then exit. Anything else on the command line is
+ignored.
+.TP
+\fB-v\fP, \fB--invert-match\fP
+Invert the sense of the match, so that lines which do \fInot\fP match any of
+the patterns are the ones that are found.
+.TP
+\fB-w\fP, \fB--word-regex\fP, \fB--word-regexp\fP
+Force the patterns to match only whole words. This is equivalent to having \eb
+at the start and end of the pattern. This option applies only to the patterns
+that are matched against the contents of files; it does not apply to patterns
+specified by any of the \fB--include\fP or \fB--exclude\fP options.
+.TP
+\fB-x\fP, \fB--line-regex\fP, \fB--line-regexp\fP
+Force the patterns to be anchored (each must start matching at the beginning of
+a line) and in addition, require them to match entire lines. This is equivalent
+to having ^ and $ characters at the start and end of each alternative top-level
+branch in every pattern. This option applies only to the patterns that are
+matched against the contents of files; it does not apply to patterns specified
+by any of the \fB--include\fP or \fB--exclude\fP options.
+.
+.
+.SH "ENVIRONMENT VARIABLES"
+.rs
+.sp
+The environment variables \fBLC_ALL\fP and \fBLC_CTYPE\fP are examined, in that
+order, for a locale. The first one that is set is used. This can be overridden
+by the \fB--locale\fP option. If no locale is set, the PCRE2 library's default
+(usually the "C" locale) is used.
+.
+.
+.SH "NEWLINES"
+.rs
+.sp
+The \fB-N\fP (\fB--newline\fP) option allows \fBpcre2grep\fP to scan files with
+different newline conventions from the default. Any parts of the input files
+that are written to the standard output are copied identically, with whatever
+newline sequences they have in the input. However, the setting of this option
+does not affect the interpretation of files specified by the \fB-f\fP,
+\fB--exclude-from\fP, or \fB--include-from\fP options, which are assumed to use
+the operating system's standard newline sequence, nor does it affect the way in
+which \fBpcre2grep\fP writes informational messages to the standard error and
+output streams. For these it uses the string "\en" to indicate newlines,
+relying on the C I/O library to convert this to an appropriate sequence.
+.
+.
+.SH "OPTIONS COMPATIBILITY"
+.rs
+.sp
+Many of the short and long forms of \fBpcre2grep\fP's options are the same
+as in the GNU \fBgrep\fP program. Any long option of the form
+\fB--xxx-regexp\fP (GNU terminology) is also available as \fB--xxx-regex\fP
+(PCRE2 terminology). However, the \fB--file-list\fP, \fB--file-offsets\fP,
+\fB--include-dir\fP, \fB--line-offsets\fP, \fB--locale\fP, \fB--match-limit\fP,
+\fB-M\fP, \fB--multiline\fP, \fB-N\fP, \fB--newline\fP, \fB--om-separator\fP,
+\fB--recursion-limit\fP, \fB-u\fP, and \fB--utf-8\fP options are specific to
+\fBpcre2grep\fP, as is the use of the \fB--only-matching\fP option with a
+capturing parentheses number.
+.P
+Although most of the common options work the same way, a few are different in
+\fBpcre2grep\fP. For example, the \fB--include\fP option's argument is a glob
+for GNU \fBgrep\fP, but a regular expression for \fBpcre2grep\fP. If both the
+\fB-c\fP and \fB-l\fP options are given, GNU grep lists only file names,
+without counts, but \fBpcre2grep\fP gives the counts as well.
+.
+.
+.SH "OPTIONS WITH DATA"
+.rs
+.sp
+There are four different ways in which an option with data can be specified.
+If a short form option is used, the data may follow immediately, or (with one
+exception) in the next command line item. For example:
+.sp
+ -f/some/file
+ -f /some/file
+.sp
+The exception is the \fB-o\fP option, which may appear with or without data.
+Because of this, if data is present, it must follow immediately in the same
+item, for example -o3.
+.P
+If a long form option is used, the data may appear in the same command line
+item, separated by an equals character, or (with two exceptions) it may appear
+in the next command line item. For example:
+.sp
+ --file=/some/file
+ --file /some/file
+.sp
+Note, however, that if you want to supply a file name beginning with ~ as data
+in a shell command, and have the shell expand ~ to a home directory, you must
+separate the file name from the option, because the shell does not treat ~
+specially unless it is at the start of an item.
+.P
+The exceptions to the above are the \fB--colour\fP (or \fB--color\fP) and
+\fB--only-matching\fP options, for which the data is optional. If one of these
+options does have data, it must be given in the first form, using an equals
+character. Otherwise \fBpcre2grep\fP will assume that it has no data.
+.
+.
+.SH "MATCHING ERRORS"
+.rs
+.sp
+It is possible to supply a regular expression that takes a very long time to
+fail to match certain lines. Such patterns normally involve nested indefinite
+repeats, for example: (a+)*\ed when matched against a line of a's with no final
+digit. The PCRE2 matching function has a resource limit that causes it to abort
+in these circumstances. If this happens, \fBpcre2grep\fP outputs an error
+message and the line that caused the problem to the standard error stream. If
+there are more than 20 such errors, \fBpcre2grep\fP gives up.
+.P
+The \fB--match-limit\fP option of \fBpcre2grep\fP can be used to set the
+overall resource limit; there is a second option called \fB--recursion-limit\fP
+that sets a limit on the amount of memory (usually stack) that is used (see the
+discussion of these options above).
+.
+.
+.SH DIAGNOSTICS
+.rs
+.sp
+Exit status is 0 if any matches were found, 1 if no matches were found, and 2
+for syntax errors, overlong lines, non-existent or inaccessible files (even if
+matches were found in other files) or too many matching errors. Using the
+\fB-s\fP option to suppress error messages about inaccessible files does not
+affect the return code.

+
+NAME
+ pcre2grep - a grep with Perl-compatible regular expressions.
+
+SYNOPSIS
+ pcre2grep [options] [long options] [pattern] [path1 path2 ...]
+
+
+DESCRIPTION
+
+ pcre2grep searches files for character patterns, in the same way as
+ other grep commands do, but it uses the PCRE2 regular expression
+ library to support patterns that are compatible with the regular
+ expressions of Perl 5. See pcre2syntax(3) for a quick-reference summary
+ of pattern syntax, or pcre2pattern(3) for a full description of the
+ syntax and semantics of the regular expressions that PCRE2 supports.
+
+ Patterns, whether supplied on the command line or in a separate file,
+ are given without delimiters. For example:
+
+ pcre2grep Thursday /etc/motd
+
+ If you attempt to use delimiters (for example, by surrounding a pattern
+ with slashes, as is common in Perl scripts), they are interpreted as
+ part of the pattern. Quotes can of course be used to delimit patterns
+ on the command line because they are interpreted by the shell, and
+ indeed quotes are required if a pattern contains white space or shell
+ metacharacters.
+
+ The first argument that follows any option settings is treated as the
+ single pattern to be matched when neither -e nor -f is present. Con-
+ versely, when one or both of these options are used to specify pat-
+ terns, all arguments are treated as path names. At least one of -e, -f,
+ or an argument pattern must be provided.
+
+ If no files are specified, pcre2grep reads the standard input. The
+ standard input can also be referenced by a name consisting of a single
+ hyphen. For example:
+
+ pcre2grep some-pattern file1 - file3
+
+ Input files are searched line by line. By default, each line that
+ matches a pattern is copied to the standard output, and if there is
+ more than one file, the file name is output at the start of each line,
+ followed by a colon. However, there are options that can change how
+ pcre2grep behaves. In particular, the -M option makes it possible to
+ search for strings that span line boundaries. What defines a line
+ boundary is controlled by the -N (--newline) option.
+
+ The amount of memory used for buffering files that are being scanned is
+ controlled by a parameter that can be set by the --buffer-size option.
+ The default value for this parameter is specified when pcre2grep is
+ built, with the default default being 20K. A block of memory three
+ times this size is used (to allow for buffering "before" and "after"
+ lines). An error occurs if a line overflows the buffer.
+
+ Patterns can be no longer than 8K or BUFSIZ bytes, whichever is the
+ greater. BUFSIZ is defined in <stdio.h>. When there is more than one
+ pattern (specified by the use of -e and/or -f), each pattern is applied
+ to each line in the order in which they are defined, except that all
+ the -e patterns are tried before the -f patterns.
+
+ By default, as soon as one pattern matches a line, no further patterns
+ are considered. However, if --colour (or --color) is used to colour the
+ matching substrings, or if --only-matching, --file-offsets, or --line-
+ offsets is used to output only the part of the line that matched
+ (either shown literally, or as an offset), scanning resumes immediately
+ following the match, so that further matches on the same line can be
+ found. If there are multiple patterns, they are all tried on the
+ remainder of the line, but patterns that follow the one that matched
+ are not tried on the earlier part of the line.
+
+ This behaviour means that the order in which multiple patterns are
+ specified can affect the output when one of the above options is used.
+ This is no longer the same behaviour as GNU grep, which now manages to
+ display earlier matches for later patterns (as long as there is no
+ overlap).
+
+ Patterns that can match an empty string are accepted, but empty string
+ matches are never recognized. An example is the pattern
+ "(super)?(man)?", in which all components are optional. This pattern
+ finds all occurrences of both "super" and "man"; the output differs
+ from matching with "super|man" when only the matching substrings are
+ being shown.
+
+ If the LC_ALL or LC_CTYPE environment variable is set, pcre2grep uses
+ the value to set a locale when calling the PCRE2 library. The --locale
+ option can be used to override this.
+
+
+SUPPORT FOR COMPRESSED FILES
+
+ It is possible to compile pcre2grep so that it uses libz or libbz2 to
+ read files whose names end in .gz or .bz2, respectively. You can find
+ out whether your binary has support for one or both of these file types
+ by running it with the --help option. If the appropriate support is not
+ present, files are treated as plain text. The standard input is always
+ so treated.
+
+
+BINARY FILES
+
+ By default, a file that contains a binary zero byte within the first
+ 1024 bytes is identified as a binary file, and is processed specially.
+ (GNU grep also identifies binary files in this manner.) See the
+ --binary-files option for a means of changing the way binary files are
+ handled.
+
+
+OPTIONS
+
+ The order in which some of the options appear can affect the output.
+ For example, both the -h and -l options affect the printing of file
+ names. Whichever comes later in the command line will be the one that
+ takes effect. Similarly, except where noted below, if an option is
+ given twice, the later setting is used. Numerical values for options
+ may be followed by K or M, to signify multiplication by 1024 or
+ 1024*1024 respectively.
+
+ -- This terminates the list of options. It is useful if the next
+ item on the command line starts with a hyphen but is not an
+ option. This allows for the processing of patterns and file
+ names that start with hyphens.
+
+ -A number, --after-context=number
+ Output number lines of context after each matching line. If
+ file names and/or line numbers are being output, a hyphen
+ separator is used instead of a colon for the context lines. A
+ line containing "--" is output between each group of lines,
+ unless they are in fact contiguous in the input file. The
+ value of number is expected to be relatively small. However,
+ pcre2grep guarantees to have up to 8K of following text
+ available for context output.
+
+ -a, --text
+ Treat binary files as text. This is equivalent to --binary-
+ files=text.
+
+ -B number, --before-context=number
+ Output number lines of context before each matching line. If
+ file names and/or line numbers are being output, a hyphen
+ separator is used instead of a colon for the context lines. A
+ line containing "--" is output between each group of lines,
+ unless they are in fact contiguous in the input file. The
+ value of number is expected to be relatively small. However,
+ pcre2grep guarantees to have up to 8K of preceding text
+ available for context output.
+
+ --binary-files=word
+ Specify how binary files are to be processed. If the word is
+ "binary" (the default), pattern matching is performed on
+ binary files, but the only output is "Binary file <name>
+ matches" when a match succeeds. If the word is "text", which
+ is equivalent to the -a or --text option, binary files are
+ processed in the same way as any other file. In this case,
+ when a match succeeds, the output may be binary garbage,
+ which can have nasty effects if sent to a terminal. If the
+ word is "without-match", which is equivalent to the -I
+ option, binary files are not processed at all; they are
+ assumed not to be of interest and are skipped without causing
+ any output or affecting the return code.
+
+ --buffer-size=number
+ Set the parameter that controls how much memory is used for
+ buffering files that are being scanned.
+
+ -C number, --context=number
+ Output number lines of context both before and after each
+ matching line. This is equivalent to setting both -A and -B
+ to the same value.
+
+ -c, --count
+ Do not output lines from the files that are being scanned;
+ instead output the number of matches (or non-matches if -v is
+ used) that would otherwise have caused lines to be shown. By
+ default, this count is the same as the number of suppressed
+ lines, but if the -M (multiline) option is used (without -v),
+ there may be more suppressed lines than the number of
+ matches.
+
+ If no lines are selected, the number zero is output. If sev-
+ eral files are are being scanned, a count is output for each
+ of them. However, if the --files-with-matches option is also
+ used, only those files whose counts are greater than zero are
+ listed. When -c is used, the -A, -B, and -C options are
+ ignored.
+
+ --colour, --color
+ If this option is given without any data, it is equivalent to
+ "--colour=auto". If data is required, it must be given in
+ the same shell item, separated by an equals sign.
+
+ --colour=value, --color=value
+ This option specifies under what circumstances the parts of a
+ line that matched a pattern should be coloured in the output.
+ By default, the output is not coloured. The value (which is
+ optional, see above) may be "never", "always", or "auto". In
+ the latter case, colouring happens only if the standard out-
+ put is connected to a terminal. More resources are used when
+ colouring is enabled, because pcre2grep has to search for all
+ possible matches in a line, not just one, in order to colour
+ them all.
+
+ The colour that is used can be specified by setting the envi-
+ ronment variable PCRE2GREP_COLOUR or PCRE2GREP_COLOR. The
+ value of this variable should be a string of two numbers,
+ separated by a semicolon. They are copied directly into the
+ control string for setting colour on a terminal, so it is
+ your responsibility to ensure that they make sense. If nei-
+ ther of the environment variables is set, the default is
+ "1;31", which gives red.
+
+ -D action, --devices=action
+ If an input path is not a regular file or a directory,
+ "action" specifies how it is to be processed. Valid values
+ are "read" (the default) or "skip" (silently skip the path).
+
+ -d action, --directories=action
+ If an input path is a directory, "action" specifies how it is
+ to be processed. Valid values are "read" (the default in
+ non-Windows environments, for compatibility with GNU grep),
+ "recurse" (equivalent to the -r option), or "skip" (silently
+ skip the path, the default in Windows environments). In the
+ "read" case, directories are read as if they were ordinary
+ files. In some operating systems the effect of reading a
+ directory like this is an immediate end-of-file; in others it
+ may provoke an error.
+
+ -e pattern, --regex=pattern, --regexp=pattern
+ Specify a pattern to be matched. This option can be used mul-
+ tiple times in order to specify several patterns. It can also
+ be used as a way of specifying a single pattern that starts
+ with a hyphen. When -e is used, no argument pattern is taken
+ from the command line; all arguments are treated as file
+ names. There is no limit to the number of patterns. They are
+ applied to each line in the order in which they are defined
+ until one matches.
+
+ If -f is used with -e, the command line patterns are matched
+ first, followed by the patterns from the file(s), independent
+ of the order in which these options are specified. Note that
+ multiple use of -e is not the same as a single pattern with
+ alternatives. For example, X|Y finds the first character in a
+ line that is X or Y, whereas if the two patterns are given
+ separately, with X first, pcre2grep finds X if it is present,
+ even if it follows Y in the line. It finds Y only if there is
+ no X in the line. This matters only if you are using -o or
+ --colo(u)r to show the part(s) of the line that matched.
+
+ --exclude=pattern
+ Files (but not directories) whose names match the pattern are
+ skipped without being processed. This applies to all files,
+ whether listed on the command line, obtained from --file-
+ list, or by scanning a directory. The pattern is a PCRE2 reg-
+ ular expression, and is matched against the final component
+ of the file name, not the entire path. The -F, -w, and -x
+ options do not apply to this pattern. The option may be given
+ any number of times in order to specify multiple patterns. If
+ a file name matches both an --include and an --exclude pat-
+ tern, it is excluded. There is no short form for this option.
+
+ --exclude-from=filename
+ Treat each non-empty line of the file as the data for an
+ --exclude option. What constitutes a newline when reading the
+ file is the operating system's default. The --newline option
+ has no effect on this option. This option may be given more
+ than once in order to specify a number of files to read.
+
+ --exclude-dir=pattern
+ Directories whose names match the pattern are skipped without
+ being processed, whatever the setting of the --recursive
+ option. This applies to all directories, whether listed on
+ the command line, obtained from --file-list, or by scanning a
+ parent directory. The pattern is a PCRE2 regular expression,
+ and is matched against the final component of the directory
+ name, not the entire path. The -F, -w, and -x options do not
+ apply to this pattern. The option may be given any number of
+ times in order to specify more than one pattern. If a direc-
+ tory matches both --include-dir and --exclude-dir, it is
+ excluded. There is no short form for this option.
+
+ -F, --fixed-strings
+ Interpret each data-matching pattern as a list of fixed
+ strings, separated by newlines, instead of as a regular
+ expression. What constitutes a newline for this purpose is
+ controlled by the --newline option. The -w (match as a word)
+ and -x (match whole line) options can be used with -F. They
+ apply to each of the fixed strings. A line is selected if any
+ of the fixed strings are found in it (subject to -w or -x, if
+ present). This option applies only to the patterns that are
+ matched against the contents of files; it does not apply to
+ patterns specified by any of the --include or --exclude
+ options.
+
+ -f filename, --file=filename
+ Read patterns from the file, one per line, and match them
+ against each line of input. What constitutes a newline when
+ reading the file is the operating system's default. The
+ --newline option has no effect on this option. Trailing white
+ space is removed from each line, and blank lines are ignored.
+ An empty file contains no patterns and therefore matches
+ nothing. See also the comments about multiple patterns versus
+ a single pattern with alternatives in the description of -e
+ above.
+
+ If this option is given more than once, all the specified
+ files are read. A data line is output if any of the patterns
+ match it. A file name can be given as "-" to refer to the
+ standard input. When -f is used, patterns specified on the
+ command line using -e may also be present; they are tested
+ before the file's patterns. However, no other pattern is
+ taken from the command line; all arguments are treated as the
+ names of paths to be searched.
+
+ --file-list=filename
+ Read a list of files and/or directories that are to be
+ scanned from the given file, one per line. Trailing white
+ space is removed from each line, and blank lines are ignored.
+ These paths are processed before any that are listed on the
+ command line. The file name can be given as "-" to refer to
+ the standard input. If --file and --file-list are both spec-
+ ified as "-", patterns are read first. This is useful only
+ when the standard input is a terminal, from which further
+ lines (the list of files) can be read after an end-of-file
+ indication. If this option is given more than once, all the
+ specified files are read.
+
+ --file-offsets
+ Instead of showing lines or parts of lines that match, show
+ each match as an offset from the start of the file and a
+ length, separated by a comma. In this mode, no context is
+ shown. That is, the -A, -B, and -C options are ignored. If
+ there is more than one match in a line, each of them is shown
+ separately. This option is mutually exclusive with --line-
+ offsets and --only-matching.
+
+ -H, --with-filename
+ Force the inclusion of the file name at the start of output
+ lines when searching a single file. By default, the file name
+ is not shown in this case. For matching lines, the file name
+ is followed by a colon; for context lines, a hyphen separator
+ is used. If a line number is also being output, it follows
+ the file name. When the -M option causes a pattern to match
+ more than one line, only the first is preceded by the file
+ name.
+
+ -h, --no-filename
+ Suppress the output file names when searching multiple files.
+ By default, file names are shown when multiple files are
+ searched. For matching lines, the file name is followed by a
+ colon; for context lines, a hyphen separator is used. If a
+ line number is also being output, it follows the file name.
+
+ --help Output a help message, giving brief details of the command
+ options and file type support, and then exit. Anything else
+ on the command line is ignored.
+
+ -I Ignore binary files. This is equivalent to --binary-
+ files=without-match.
+
+ -i, --ignore-case
+ Ignore upper/lower case distinctions during comparisons.
+
+ --include=pattern
+ If any --include patterns are specified, the only files that
+ are processed are those that match one of the patterns (and
+ do not match an --exclude pattern). This option does not
+ affect directories, but it applies to all files, whether
+ listed on the command line, obtained from --file-list, or by
+ scanning a directory. The pattern is a PCRE2 regular expres-
+ sion, and is matched against the final component of the file
+ name, not the entire path. The -F, -w, and -x options do not
+ apply to this pattern. The option may be given any number of
+ times. If a file name matches both an --include and an
+ --exclude pattern, it is excluded. There is no short form
+ for this option.
+
+ --include-from=filename
+ Treat each non-empty line of the file as the data for an
+ --include option. What constitutes a newline for this purpose
+ is the operating system's default. The --newline option has
+ no effect on this option. This option may be given any number
+ of times; all the files are read.
+
+ --include-dir=pattern
+ If any --include-dir patterns are specified, the only direc-
+ tories that are processed are those that match one of the
+ patterns (and do not match an --exclude-dir pattern). This
+ applies to all directories, whether listed on the command
+ line, obtained from --file-list, or by scanning a parent
+ directory. The pattern is a PCRE2 regular expression, and is
+ matched against the final component of the directory name,
+ not the entire path. The -F, -w, and -x options do not apply
+ to this pattern. The option may be given any number of times.
+ If a directory matches both --include-dir and --exclude-dir,
+ it is excluded. There is no short form for this option.
+
+ -L, --files-without-match
+ Instead of outputting lines from the files, just output the
+ names of the files that do not contain any lines that would
+ have been output. Each file name is output once, on a sepa-
+ rate line.
+
+ -l, --files-with-matches
+ Instead of outputting lines from the files, just output the
+ names of the files containing lines that would have been out-
+ put. Each file name is output once, on a separate line.
+ Searching normally stops as soon as a matching line is found
+ in a file. However, if the -c (count) option is also used,
+ matching continues in order to obtain the correct count, and
+ those files that have at least one match are listed along
+ with their counts. Using this option with -c is a way of sup-
+ pressing the listing of files with no matches.
+
+ --label=name
+ This option supplies a name to be used for the standard input
+ when file names are being output. If not supplied, "(standard
+ input)" is used. There is no short form for this option.
+
+ --line-buffered
+ When this option is given, input is read and processed line
+ by line, and the output is flushed after each write. By
+ default, input is read in large chunks, unless pcre2grep can
+ determine that it is reading from a terminal (which is cur-
+ rently possible only in Unix-like environments). Output to
+ terminal is normally automatically flushed by the operating
+ system. This option can be useful when the input or output is
+ attached to a pipe and you do not want pcre2grep to buffer up
+ large amounts of data. However, its use will affect perfor-
+ mance, and the -M (multiline) option ceases to work.
+
+ --line-offsets
+ Instead of showing lines or parts of lines that match, show
+ each match as a line number, the offset from the start of the
+ line, and a length. The line number is terminated by a colon
+ (as usual; see the -n option), and the offset and length are
+ separated by a comma. In this mode, no context is shown.
+ That is, the -A, -B, and -C options are ignored. If there is
+ more than one match in a line, each of them is shown sepa-
+ rately. This option is mutually exclusive with --file-offsets
+ and --only-matching.
+
+ --locale=locale-name
+ This option specifies a locale to be used for pattern match-
+ ing. It overrides the value in the LC_ALL or LC_CTYPE envi-
+ ronment variables. If no locale is specified, the PCRE2
+ library's default (usually the "C" locale) is used. There is
+ no short form for this option.
+
+ --match-limit=number
+ Processing some regular expression patterns can require a
+ very large amount of memory, leading in some cases to a pro-
+ gram crash if not enough is available. Other patterns may
+ take a very long time to search for all possible matching
+ strings. The pcre2_match() function that is called by
+ pcre2grep to do the matching has two parameters that can
+ limit the resources that it uses.
+
+ The --match-limit option provides a means of limiting
+ resource usage when processing patterns that are not going to
+ match, but which have a very large number of possibilities in
+ their search trees. The classic example is a pattern that
+ uses nested unlimited repeats. Internally, PCRE2 uses a func-
+ tion called match() which it calls repeatedly (sometimes
+ recursively). The limit set by --match-limit is imposed on
+ the number of times this function is called during a match,
+ which has the effect of limiting the amount of backtracking
+ that can take place.
+
+ The --recursion-limit option is similar to --match-limit, but
+ instead of limiting the total number of times that match() is
+ called, it limits the depth of recursive calls, which in turn
+ limits the amount of memory that can be used. The recursion
+ depth is a smaller number than the total number of calls,
+ because not all calls to match() are recursive. This limit is
+ of use only if it is set smaller than --match-limit.
+
+ There are no short forms for these options. The default set-
+ tings are specified when the PCRE2 library is compiled, with
+ the default default being 10 million.
+
+ -M, --multiline
+ Allow patterns to match more than one line. When this option
+ is given, patterns may usefully contain literal newline char-
+ acters and internal occurrences of ^ and $ characters. The
+ output for a successful match may consist of more than one
+ line. The first is the line in which the match started, and
+ the last is the line in which the match ended. If the matched
+ string ends with a newline sequence the output ends at the
+ end of that line.
+
+ When this option is set, the PCRE2 library is called in "mul-
+ tiline" mode. However, pcre2grep still processes the input
+ line by line. The difference is that a matched string may
+ extend past the end of a line and continue on one or more
+ subsequent lines. The newline sequence must be matched as
+ part of the pattern. For example, to find the phrase "regular
+ expression" in a file where "regular" might be at the end of
+ a line and "expression" at the start of the next line, you
+ could use this command:
+
+ pcre2grep -M 'regular\s+expression' <file>
+
+ The \s escape sequence matches any white space character,
+ including newlines, and is followed by + so as to match
+ trailing white space on the first line as well as possibly
+ handling a two-character newline sequence.
+
+ There is a limit to the number of lines that can be matched,
+ imposed by the way that pcre2grep buffers the input file as
+ it scans it. However, pcre2grep ensures that at least 8K
+ characters or the rest of the file (whichever is the shorter)
+ are available for forward matching, and similarly the previ-
+ ous 8K characters (or all the previous characters, if fewer
+ than 8K) are guaranteed to be available for lookbehind asser-
+ tions. The -M option does not work when input is read line by
+ line (see --line-buffered.)
+
+ -N newline-type, --newline=newline-type
+ The PCRE2 library supports five different conventions for
+ indicating the ends of lines. They are the single-character
+ sequences CR (carriage return) and LF (linefeed), the two-
+ character sequence CRLF, an "anycrlf" convention, which rec-
+ ognizes any of the preceding three types, and an "any" con-
+ vention, in which any Unicode line ending sequence is assumed
+ to end a line. The Unicode sequences are the three just men-
+ tioned, plus VT (vertical tab, U+000B), FF (form feed,
+ U+000C), NEL (next line, U+0085), LS (line separator,
+ U+2028), and PS (paragraph separator, U+2029).
+
+ When the PCRE2 library is built, a default line-ending
+ sequence is specified. This is normally the standard
+ sequence for the operating system. Unless otherwise specified
+ by this option, pcre2grep uses the library's default. The
+ possible values for this option are CR, LF, CRLF, ANYCRLF, or
+ ANY. This makes it possible to use pcre2grep to scan files
+ that have come from other environments without having to mod-
+ ify their line endings. If the data that is being scanned
+ does not agree with the convention set by this option,
+ pcre2grep may behave in strange ways. Note that this option
+ does not apply to files specified by the -f, --exclude-from,
+ or --include-from options, which are expected to use the
+ operating system's standard newline sequence.
+
+ -n, --line-number
+ Precede each output line by its line number in the file, fol-
+ lowed by a colon for matching lines or a hyphen for context
+ lines. If the file name is also being output, it precedes the
+ line number. When the -M option causes a pattern to match
+ more than one line, only the first is preceded by its line
+ number. This option is forced if --line-offsets is used.
+
+ --no-jit If the PCRE2 library is built with support for just-in-time
+ compiling (which speeds up matching), pcre2grep automatically
+ makes use of this, unless it was explicitly disabled at build
+ time. This option can be used to disable the use of JIT at
+ run time. It is provided for testing and working round prob-
+ lems. It should never be needed in normal use.
+
+ -o, --only-matching
+ Show only the part of the line that matched a pattern instead
+ of the whole line. In this mode, no context is shown. That
+ is, the -A, -B, and -C options are ignored. If there is more
+ than one match in a line, each of them is shown separately.
+ If -o is combined with -v (invert the sense of the match to
+ find non-matching lines), no output is generated, but the
+ return code is set appropriately. If the matched portion of
+ the line is empty, nothing is output unless the file name or
+ line number are being printed, in which case they are shown
+ on an otherwise empty line. This option is mutually exclusive
+ with --file-offsets and --line-offsets.
+
+ -onumber, --only-matching=number
+ Show only the part of the line that matched the capturing
+ parentheses of the given number. Up to 32 capturing parenthe-
+ ses are supported, and -o0 is equivalent to -o without a num-
+ ber. Because these options can be given without an argument
+ (see above), if an argument is present, it must be given in
+ the same shell item, for example, -o3 or --only-matching=2.
+ The comments given for the non-argument case above also apply
+ to this case. If the specified capturing parentheses do not
+ exist in the pattern, or were not set in the match, nothing
+ is output unless the file name or line number are being out-
+ put.
+
+ If this option is given multiple times, multiple substrings
+ are output, in the order the options are given. For example,
+ -o3 -o1 -o3 causes the substrings matched by capturing paren-
+ theses 3 and 1 and then 3 again to be output. By default,
+ there is no separator (but see the next option).
+
+ --om-separator=text
+ Specify a separating string for multiple occurrences of -o.
+ The default is an empty string. Separating strings are never
+ coloured.
+
+ -q, --quiet
+ Work quietly, that is, display nothing except error messages.
+ The exit status indicates whether or not any matches were
+ found.
+
+ -r, --recursive
+ If any given path is a directory, recursively scan the files
+ it contains, taking note of any --include and --exclude set-
+ tings. By default, a directory is read as a normal file; in
+ some operating systems this gives an immediate end-of-file.
+ This option is a shorthand for setting the -d option to
+ "recurse".
+
+ --recursion-limit=number
+ See --match-limit above.
+
+ -s, --no-messages
+ Suppress error messages about non-existent or unreadable
+ files. Such files are quietly skipped. However, the return
+ code is still 2, even if matches were found in other files.
+
+ -u, --utf-8
+ Operate in UTF-8 mode. This option is available only if PCRE2
+ has been compiled with UTF-8 support. All patterns (including
+ those for any --exclude and --include options) and all sub-
+ ject lines that are scanned must be valid strings of UTF-8
+ characters.
+
+ -V, --version
+ Write the version numbers of pcre2grep and the PCRE2 library
+ to the standard output and then exit. Anything else on the
+ command line is ignored.
+
+ -v, --invert-match
+ Invert the sense of the match, so that lines which do not
+ match any of the patterns are the ones that are found.
+
+ -w, --word-regex, --word-regexp
+ Force the patterns to match only whole words. This is equiva-
+ lent to having \b at the start and end of the pattern. This
+ option applies only to the patterns that are matched against
+ the contents of files; it does not apply to patterns speci-
+ fied by any of the --include or --exclude options.
+
+ -x, --line-regex, --line-regexp
+ Force the patterns to be anchored (each must start matching
+ at the beginning of a line) and in addition, require them to
+ match entire lines. This is equivalent to having ^ and $
+ characters at the start and end of each alternative top-level
+ branch in every pattern. This option applies only to the pat-
+ terns that are matched against the contents of files; it does
+ not apply to patterns specified by any of the --include or
+ --exclude options.
+
+
+ENVIRONMENT VARIABLES
+
+ The environment variables LC_ALL and LC_CTYPE are examined, in that
+ order, for a locale. The first one that is set is used. This can be
+ overridden by the --locale option. If no locale is set, the PCRE2
+ library's default (usually the "C" locale) is used.
+
+
+NEWLINES
+
+ The -N (--newline) option allows pcre2grep to scan files with different
+ newline conventions from the default. Any parts of the input files that
+ are written to the standard output are copied identically, with what-
+ ever newline sequences they have in the input. However, the setting of
+ this option does not affect the interpretation of files specified by
+ the -f, --exclude-from, or --include-from options, which are assumed to
+ use the operating system's standard newline sequence, nor does it
+ affect the way in which pcre2grep writes informational messages to the
+ standard error and output streams. For these it uses the string "\n" to
+ indicate newlines, relying on the C I/O library to convert this to an
+ appropriate sequence.
+
+
+OPTIONS COMPATIBILITY
+
+ Many of the short and long forms of pcre2grep's options are the same as
+ in the GNU grep program. Any long option of the form --xxx-regexp (GNU
+ terminology) is also available as --xxx-regex (PCRE2 terminology). How-
+ ever, the --file-list, --file-offsets, --include-dir, --line-offsets,
+ --locale, --match-limit, -M, --multiline, -N, --newline, --om-separa-
+ tor, --recursion-limit, -u, and --utf-8 options are specific to
+ pcre2grep, as is the use of the --only-matching option with a capturing
+ parentheses number.
+
+ Although most of the common options work the same way, a few are dif-
+ ferent in pcre2grep. For example, the --include option's argument is a
+ glob for GNU grep, but a regular expression for pcre2grep. If both the
+ -c and -l options are given, GNU grep lists only file names, without
+ counts, but pcre2grep gives the counts as well.
+
+
+OPTIONS WITH DATA
+
+ There are four different ways in which an option with data can be spec-
+ ified. If a short form option is used, the data may follow immedi-
+ ately, or (with one exception) in the next command line item. For exam-
+ ple:
+
+ -f/some/file
+ -f /some/file
+
+ The exception is the -o option, which may appear with or without data.
+ Because of this, if data is present, it must follow immediately in the
+ same item, for example -o3.
+
+ If a long form option is used, the data may appear in the same command
+ line item, separated by an equals character, or (with two exceptions)
+ it may appear in the next command line item. For example:
+
+ --file=/some/file
+ --file /some/file
+
+ Note, however, that if you want to supply a file name beginning with ~
+ as data in a shell command, and have the shell expand ~ to a home
+ directory, you must separate the file name from the option, because the
+ shell does not treat ~ specially unless it is at the start of an item.
+
+ The exceptions to the above are the --colour (or --color) and --only-
+ matching options, for which the data is optional. If one of these
+ options does have data, it must be given in the first form, using an
+ equals character. Otherwise pcre2grep will assume that it has no data.
+
+
+MATCHING ERRORS
+
+ It is possible to supply a regular expression that takes a very long
+ time to fail to match certain lines. Such patterns normally involve
+ nested indefinite repeats, for example: (a+)*\d when matched against a
+ line of a's with no final digit. The PCRE2 matching function has a
+ resource limit that causes it to abort in these circumstances. If this
+ happens, pcre2grep outputs an error message and the line that caused
+ the problem to the standard error stream. If there are more than 20
+ such errors, pcre2grep gives up.
+
+ The --match-limit option of pcre2grep can be used to set the overall
+ resource limit; there is a second option called --recursion-limit that
+ sets a limit on the amount of memory (usually stack) that is used (see
+ the discussion of these options above).
+
+
+DIAGNOSTICS
+
+ Exit status is 0 if any matches were found, 1 if no matches were found,
+ and 2 for syntax errors, overlong lines, non-existent or inaccessible
+ files (even if matches were found in other files) or too many matching
+ errors. Using the -s option to suppress error messages about inaccessi-
+ ble files does not affect the return code.

+PCRE2 - Perl-compatible regular expressions (revised API)
+.SH "PCRE2 JUST-IN-TIME COMPILER SUPPORT"
+.rs
+.sp
+Just-in-time compiling is a heavyweight optimization that can greatly speed up
+pattern matching. However, it comes at the cost of extra processing before the
+match is performed, so it is of most benefit when the same pattern is going to
+be matched many times. This does not necessarily mean many calls of a matching
+function; if the pattern is not anchored, matching attempts may take place many
+times at various positions in the subject, even for a single call. Therefore,
+if the subject string is very long, it may still pay to use JIT even for
+one-off matches. JIT support is available for all of the 8-bit, 16-bit and
+32-bit PCRE2 libraries.
+.P
+JIT support applies only to the traditional Perl-compatible matching function.
+It does not apply when the DFA matching function is being used. The code for
+this support was written by Zoltan Herczeg.

+.SH "AVAILABILITY OF JIT SUPPORT"
+.rs
+.sp
+JIT support is an optional feature of PCRE2. The "configure" option
+--enable-jit (or equivalent CMake option) must be set when PCRE2 is built if
+you want to use JIT. The support is limited to the following hardware
+platforms:
+.sp
+ ARM 32-bit (v5, v7, and Thumb2)
+ ARM 64-bit
+ Intel x86 32-bit and 64-bit
+ MIPS 32-bit and 64-bit
+ Power PC 32-bit and 64-bit
+ SPARC 32-bit
+.sp
+If --enable-jit is set on an unsupported platform, compilation fails.
+.P
+A program can tell if JIT support is available by calling \fBpcre2_config()\fP
+with the PCRE2_CONFIG_JIT option. The result is 1 when JIT is available, and 0
+otherwise. However, a simple program does not need to check this in order to
+use JIT. The API is implemented in a way that falls back to the interpretive
+code if JIT is not available. For programs that need the best possible
+performance, there is also a "fast path" API that is JIT-specific.
+.
+.
+.SH "SIMPLE USE OF JIT"
+.rs
+.sp
+To make use of the JIT support in the simplest way, all you have to do is to
+call \fBpcre2_jit_compile()\fP after successfully compiling a pattern with
+\fBpcre2_compile()\fP. This function has two arguments: the first is the
+compiled pattern pointer that was returned by \fBpcre2_compile()\fP, and the
+second is zero or more of the following option bits: PCRE2_JIT_COMPLETE,
+PCRE2_JIT_PARTIAL_HARD, or PCRE2_JIT_PARTIAL_SOFT.
+.P
+If JIT support is not available, a call to \fBpcre2_jit_compile()\fP does
+nothing and returns PCRE2_ERROR_JIT_BADOPTION. Otherwise, the compiled pattern
+is passed to the JIT compiler, which turns it into machine code that executes
+much faster than the normal interpretive code, but yields exactly the same
+results. The returned value from \fBpcre2_jit_compile()\fP is zero on success,
+or a negative error code.
+.P
+There is a limit to the size of pattern that JIT supports, imposed by the size
+of machine stack that it uses. The exact rules are not documented because they
+may change at any time, in particular, when new optimizations are introduced.
+If a pattern is too big, a call to \fBpcre2_jit_compile()\fB returns
+PCRE2_ERROR_NOMEMORY.
+.P
+PCRE2_JIT_COMPLETE requests the JIT compiler to generate code for complete
+matches. If you want to run partial matches using the PCRE2_PARTIAL_HARD or
+PCRE2_PARTIAL_SOFT options of \fBpcre2_match()\fP, you should set one or both
+of the other options as well as, or instead of PCRE2_JIT_COMPLETE. The JIT
+compiler generates different optimized code for each of the three modes
+(normal, soft partial, hard partial). When \fBpcre2_match()\fP is called, the
+appropriate code is run if it is available. Otherwise, the pattern is matched
+using interpretive code.
+.P
+You can call \fBpcre2_jit_compile()\fP multiple times for the same compiled
+pattern. It does nothing if it has previously compiled code for any of the
+option bits. For example, you can call it once with PCRE2_JIT_COMPLETE and
+(perhaps later, when you find you need partial matching) again with
+PCRE2_JIT_COMPLETE and PCRE2_JIT_PARTIAL_HARD. This time it will ignore
+PCRE2_JIT_COMPLETE and just compile code for partial matching. If
+\fBpcre2_jit_compile()\fP is called with no option bits set, it immediately
+returns zero. This is an alternative way of testing whether JIT is available.
+.P
+At present, it is not possible to free JIT compiled code except when the entire
+compiled pattern is freed by calling \fBpcre2_code_free()\fP.
+.P
+In some circumstances you may need to call additional functions. These are
+described in the section entitled
+.\" HTML <a href="#stackcontrol">
+.\" </a>
+"Controlling the JIT stack"
+.\"
+below.
+.P
+There are some \fBpcre2_match()\fP options that are not supported by JIT, and
+there are also some pattern items that JIT cannot handle. Details are given
+below. In both cases, matching automatically falls back to the interpretive
+code. If you want to know whether JIT was actually used for a particular match,
+you should arrange for a JIT callback function to be set up as described in the
+section entitled
+.\" HTML <a href="#stackcontrol">
+.\" </a>
+"Controlling the JIT stack"
+.\"
+below, even if you do not need to supply a non-default JIT stack. Such a
+callback function is called whenever JIT code is about to be obeyed. If the
+match-time options are not right for JIT execution, the callback function is
+not obeyed.
+.P
+If the JIT compiler finds an unsupported item, no JIT data is generated. You
+can find out if JIT matching is available after compiling a pattern by calling
+\fBpcre2_pattern_info()\fP with the PCRE2_INFO_JITSIZE option. A non-zero
+result means that JIT compilation was successful. A result of 0 means that JIT
+support is not available, or the pattern was not processed by
+\fBpcre2_jit_compile()\fP, or the JIT compiler was not able to handle the
+pattern.
+.
+.
+.SH "UNSUPPORTED OPTIONS AND PATTERN ITEMS"
+.rs
+.sp
+The \fBpcre2_match()\fP options that are supported for JIT matching are
+PCRE2_NOTBOL, PCRE2_NOTEOL, PCRE2_NOTEMPTY, PCRE2_NOTEMPTY_ATSTART,
+PCRE2_NO_UTF_CHECK, PCRE2_PARTIAL_HARD, and PCRE2_PARTIAL_SOFT. The
+PCRE2_ANCHORED option is not supported at match time.
+.P
+The only unsupported pattern items are \eC (match a single data unit) when
+running in a UTF mode, and a callout immediately before an assertion condition
+in a conditional group.
+.
+.
+.SH "RETURN VALUES FROM JIT MATCHING"
+.rs
+.sp
+When a pattern is matched using JIT matching, the return values are the same
+as those given by the interpretive \fBpcre2_match()\fP code, with the addition
+of one new error code: PCRE2_ERROR_JIT_STACKLIMIT. This means that the memory
+used for the JIT stack was insufficient. See
+.\" HTML <a href="#stackcontrol">
+.\" </a>
+"Controlling the JIT stack"
+.\"
+below for a discussion of JIT stack usage.
+.P
+The error code PCRE2_ERROR_MATCHLIMIT is returned by the JIT code if searching
+a very large pattern tree goes on for too long, as it is in the same
+circumstance when JIT is not used, but the details of exactly what is counted
+are not the same. The PCRE2_ERROR_RECURSIONLIMIT error code is never returned
+when JIT matching is used.
+.
+.
+.\" HTML <a name="stackcontrol"></a>
+.SH "CONTROLLING THE JIT STACK"
+.rs
+.sp
+When the compiled JIT code runs, it needs a block of memory to use as a stack.
+By default, it uses 32K on the machine stack. However, some large or
+complicated patterns need more than this. The error PCRE2_ERROR_JIT_STACKLIMIT
+is given when there is not enough stack. Three functions are provided for
+managing blocks of memory for use as JIT stacks. There is further discussion
+about the use of JIT stacks in the section entitled
+.\" HTML <a href="#stackfaq">
+.\" </a>
+"JIT stack FAQ"
+.\"
+below.
+.P
+The \fBpcre2_jit_stack_create()\fP function creates a JIT stack. Its arguments
+are a starting size, a maximum size, and a general context (for memory
+allocation functions, or NULL for standard memory allocation). It returns a
+pointer to an opaque structure of type \fBpcre2_jit_stack\fP, or NULL if there
+is an error. The \fBpcre2_jit_stack_free()\fP function is used to free a stack
+that is no longer needed. (For the technically minded: the address space is
+allocated by mmap or VirtualAlloc.)
+.P
+JIT uses far less memory for recursion than the interpretive code,
+and a maximum stack size of 512K to 1M should be more than enough for any
+pattern.
+.P
+The \fBpcre2_jit_stack_assign()\fP function specifies which stack JIT code
+should use. Its arguments are as follows:
+.sp
+ pcre2_match_context *mcontext
+ pcre2_jit_callback callback
+ void *data
+.sp
+The first argument is a pointer to a match context. When this is subsequently
+passed to a matching function, its information determines which JIT stack is
+used. There are three cases for the values of the other two options:
+.sp
+ (1) If \fIcallback\fP is NULL and \fIdata\fP is NULL, an internal 32K block
+ on the machine stack is used. This is the default when a match
+ context is created.
+.sp
+ (2) If \fIcallback\fP is NULL and \fIdata\fP is not NULL, \fIdata\fP must be
+ a pointer to a valid JIT stack, the result of calling
+ \fBpcre2_jit_stack_create()\fP.
+.sp
+ (3) If \fIcallback\fP is not NULL, it must point to a function that is
+ called with \fIdata\fP as an argument at the start of matching, in
+ order to set up a JIT stack. If the return from the callback
+ function is NULL, the internal 32K stack is used; otherwise the
+ return value must be a valid JIT stack, the result of calling
+ \fBpcre2_jit_stack_create()\fP.
+.sp
+A callback function is obeyed whenever JIT code is about to be run; it is not
+obeyed when \fBpcre2_match()\fP is called with options that are incompatible
+for JIT matching. A callback function can therefore be used to determine
+whether a match operation was executed by JIT or by the interpreter.
+.P
+You may safely use the same JIT stack for more than one pattern (either by
+assigning directly or by callback), as long as the patterns are matched
+sequentially in the same thread. Currently, the only way to set up
+non-sequential matches in one thread is to use callouts: if a callout function
+starts another match, that match must use a different JIT stack to the one used
+for currently suspended match(es).
+.P
+In a multithread application, if you do not
+specify a JIT stack, or if you assign or pass back NULL from a callback, that
+is thread-safe, because each thread has its own machine stack. However, if you
+assign or pass back a non-NULL JIT stack, this must be a different stack for
+each thread so that the application is thread-safe.
+.P
+Strictly speaking, even more is allowed. You can assign the same non-NULL stack
+to a match context that is used by any number of patterns, as long as they are
+not used for matching by multiple threads at the same time. For example, you
+could use the same stack in all compiled patterns, with a global mutex in the
+callback to wait until the stack is available for use. However, this is an
+inefficient solution, and not recommended.
+.P
+This is a suggestion for how a multithreaded program that needs to set up
+non-default JIT stacks might operate:
+.sp
+ During thread initalization
+ thread_local_var = pcre2_jit_stack_create(...)
+.sp
+ During thread exit
+ pcre2_jit_stack_free(thread_local_var)
+.sp
+ Use a one-line callback function
+ return thread_local_var
+.sp
+All the functions described in this section do nothing if JIT is not available.
+.
+.
+.\" HTML <a name="stackfaq"></a>
+.SH "JIT STACK FAQ"
+.rs
+.sp
+(1) Why do we need JIT stacks?
+.sp
+PCRE2 (and JIT) is a recursive, depth-first engine, so it needs a stack where
+the local data of the current node is pushed before checking its child nodes.
+Allocating real machine stack on some platforms is difficult. For example, the
+stack chain needs to be updated every time if we extend the stack on PowerPC.
+Although it is possible, its updating time overhead decreases performance. So
+we do the recursion in memory.
+.P
+(2) Why don't we simply allocate blocks of memory with \fBmalloc()\fP?
+.sp
+Modern operating systems have a nice feature: they can reserve an address space
+instead of allocating memory. We can safely allocate memory pages inside this
+address space, so the stack could grow without moving memory data (this is
+important because of pointers). Thus we can allocate 1M address space, and use
+only a single memory page (usually 4K) if that is enough. However, we can still
+grow up to 1M anytime if needed.
+.P
+(3) Who "owns" a JIT stack?
+.sp
+The owner of the stack is the user program, not the JIT studied pattern or
+anything else. The user program must ensure that if a stack is being used by
+\fBpcre2_match()\fP, (that is, it is assigned to a match context that is passed
+to the pattern currently running), that stack must not be used by any other
+threads (to avoid overwriting the same memory area). The best practice for
+multithreaded programs is to allocate a stack for each thread, and return this
+stack through the JIT callback function.
+.P
+(4) When should a JIT stack be freed?
+.sp
+You can free a JIT stack at any time, as long as it will not be used by
+\fBpcre2_match()\fP again. When you assign the stack to a match context, only a
+pointer is set. There is no reference counting or any other magic. You can free
+compiled patterns, contexts, and stacks in any order, anytime. Just \fIdo
+not\fP call \fBpcre2_match()\fP with a match context pointing to an already
+freed stack, as that will cause SEGFAULT. (Also, do not free a stack currently
+used by \fBpcre2_match()\fP in another thread). You can also replace the stack
+in a context at any time when it is not in use. You should free the previous
+stack before assigning a replacement.
+.P
+(5) Should I allocate/free a stack every time before/after calling
+\fBpcre2_match()\fP?
+.sp
+No, because this is too costly in terms of resources. However, you could
+implement some clever idea which release the stack if it is not used in let's
+say two minutes. The JIT callback can help to achieve this without keeping a
+list of patterns.
+.P
+(6) OK, the stack is for long term memory allocation. But what happens if a
+pattern causes stack overflow with a stack of 1M? Is that 1M kept until the
+stack is freed?
+.sp
+Especially on embedded sytems, it might be a good idea to release memory
+sometimes without freeing the stack. There is no API for this at the moment.
+Probably a function call which returns with the currently allocated memory for
+any stack and another which allows releasing memory (shrinking the stack) would
+be a good idea if someone needs this.
+.P
+(7) This is too much of a headache. Isn't there any better solution for JIT
+stack handling?
+.sp
+No, thanks to Windows. If POSIX threads were used everywhere, we could throw
+out this complicated API.
+.
+.
+.SH "FREEING JIT SPECULATIVE MEMORY"
+.rs
+.sp
+.nf
+.B void pcre2_jit_free_unused_memory(pcre2_general_context *\fIgcontext\fP);
+.fi
+.P
+The JIT executable allocator does not free all memory when it is possible.
+It expects new allocations, and keeps some free memory around to improve
+allocation speed. However, in low memory conditions, it might be better to free
+all possible memory. You can cause this to happen by calling
+pcre2_jit_free_unused_memory(). Its argument is a general context, for custom
+memory management, or NULL for standard memory management.
+.
+.
+.SH "EXAMPLE CODE"

+.sp
+This is a single-threaded example that specifies a JIT stack without using a
+callback. A real program should include error checking after all the function
+calls.
+.sp

+.
+.
+.SH "JIT FAST PATH API"
+.rs
+.sp
+Because the API described above falls back to interpreted matching when JIT is
+not available, it is convenient for programs that are written for general use
+in many environments. However, calling JIT via \fBpcre2_match()\fP does have a
+performance impact. Programs that are written for use where JIT is known to be
+available, and which need the best possible performance, can instead use a
+"fast path" API to call JIT matching directly instead of calling
+\fBpcre2_match()\fP (obviously only for patterns that have been successfully
+processed by \fBpcre2_jit_compile()\fP).
+.P
+The fast path function is called \fBpcre2_jit_match()\fP, and it takes exactly
+the same arguments as \fBpcre2_match()\fP. The return values are also the same,
+plus PCRE2_ERROR_JIT_BADOPTION if a matching mode (partial or complete) is
+requested that was not compiled. Unsupported option bits (for example,
+PCRE2_ANCHORED) are ignored.
+.P
+When you call \fBpcre2_match()\fP, as well as testing for invalid options, a
+number of other sanity checks are performed on the arguments. For example, if
+the subject pointer is NULL, an immediate error is given. Also, unless
+PCRE2_NO_UTF_CHECK is set, a UTF subject string is tested for validity. In the
+interests of speed, these checks do not happen on the JIT fast path, and if
+invalid data is passed, the result is undefined.
+.P
+Bypassing the sanity checks and the \fBpcre2_match()\fP wrapping can give
+speedups of more than 10%.

+PCRE2 - Perl-compatible regular expressions (revised API)
+.SH "SIZE AND OTHER LIMITATIONS"
+.rs
+.sp
+There are some size limitations in PCRE2 but it is hoped that they will never
+in practice be relevant.
+.P
+The maximum size of a compiled pattern is approximately 64K code units for the
+8-bit and 16-bit libraries if PCRE2 is compiled with the default internal
+linkage size, which is 2 bytes for these libraries. If you want to process
+regular expressions that are truly enormous, you can compile PCRE2 with an
+internal linkage size of 3 or 4 (when building the 16-bit library, 3 is rounded
+up to 4). See the \fBREADME\fP file in the source distribution and the
+.\" HREF
+\fBpcre2build\fP
+.\"
+documentation for details. In these cases the limit is substantially larger.
+However, the speed of execution is slower. In the 32-bit library, the internal
+linkage size is always 4.
+.P
+The maximum length of a source pattern string is essentially unlimited; it is
+the largest number a PCRE2_SIZE variable can hold. However, the program that
+calls \fBpcre2_compile()\fP can specify a smaller limit.
+.P
+The maximum length (in code units) of a subject string is one less than the
+largest number a PCRE2_SIZE variable can hold. PCRE2_SIZE is an unsigned
+integer type, usually defined as size_t. Its maximum value (that is
+~(PCRE2_SIZE)0) is reserved as a special indicator for zero-terminated strings
+and unset offsets.
+.P
+Note that when using the traditional matching function, PCRE2 uses recursion to
+handle subpatterns and indefinite repetition. This means that the available
+stack space may limit the size of a subject string that can be processed by
+certain patterns. For a discussion of stack issues, see the
+.\" HREF
+\fBpcre2stack\fP
+.\"
+documentation.
+.P
+All values in repeating quantifiers must be less than 65536.
+.P
+The maximum length of a lookbehind assertion is 65535 characters.
+.P
+There is no limit to the number of parenthesized subpatterns, but there can be
+no more than 65535 capturing subpatterns. There is, however, a limit to the
+depth of nesting of parenthesized subpatterns of all kinds. This is imposed in
+order to limit the amount of system stack used at compile time. The limit can
+be specified when PCRE2 is built; the default is 250.
+.P
+There is a limit to the number of forward references to subsequent subpatterns
+of around 200,000. Repeated forward references with fixed upper limits, for
+example, (?2){0,100} when subpattern number 2 is to the right, are included in
+the count. There is no limit to the number of backward references.
+.P
+The maximum length of name for a named subpattern is 32 code units, and the
+maximum number of named subpatterns is 10000.
+.P
+The maximum length of a name in a (*MARK), (*PRUNE), (*SKIP), or (*THEN) verb
+is 255 for the 8-bit library and 65535 for the 16-bit and 32-bit libraries.

+.SH NAME
+PCRE2 - Perl-compatible regular expressions (revised API)
+.SH "PCRE2 MATCHING ALGORITHMS"
+.rs
+.sp
+This document describes the two different algorithms that are available in
+PCRE2 for matching a compiled regular expression against a given subject
+string. The "standard" algorithm is the one provided by the \fBpcre2_match()\fP
+function. This works in the same as as Perl's matching function, and provide a
+Perl-compatible matching operation. The just-in-time (JIT) optimization that is
+described in the
+.\" HREF
+\fBpcre2jit\fP
+.\"
+documentation is compatible with this function.
+.P
+An alternative algorithm is provided by the \fBpcre2_dfa_match()\fP function;
+it operates in a different way, and is not Perl-compatible. This alternative
+has advantages and disadvantages compared with the standard algorithm, and
+these are described below.
+.P
+When there is only one possible way in which a given subject string can match a
+pattern, the two algorithms give the same answer. A difference arises, however,
+when there are multiple possibilities. For example, if the pattern
+.sp
+ ^<.*>
+.sp
+is matched against the string
+.sp
+ <something> <something else> <something further>
+.sp
+there are three possible answers. The standard algorithm finds only one of
+them, whereas the alternative algorithm finds all three.
+.
+.
+.SH "REGULAR EXPRESSIONS AS TREES"
+.rs
+.sp
+The set of strings that are matched by a regular expression can be represented
+as a tree structure. An unlimited repetition in the pattern makes the tree of
+infinite size, but it is still a tree. Matching the pattern to a given subject
+string (from a given starting point) can be thought of as a search of the tree.
+There are two ways to search a tree: depth-first and breadth-first, and these
+correspond to the two matching algorithms provided by PCRE2.
+.
+.
+.SH "THE STANDARD MATCHING ALGORITHM"
+.rs
+.sp
+In the terminology of Jeffrey Friedl's book "Mastering Regular Expressions",
+the standard algorithm is an "NFA algorithm". It conducts a depth-first search
+of the pattern tree. That is, it proceeds along a single path through the tree,
+checking that the subject matches what is required. When there is a mismatch,
+the algorithm tries any alternatives at the current point, and if they all
+fail, it backs up to the previous branch point in the tree, and tries the next
+alternative branch at that level. This often involves backing up (moving to the
+left) in the subject string as well. The order in which repetition branches are
+tried is controlled by the greedy or ungreedy nature of the quantifier.
+.P
+If a leaf node is reached, a matching string has been found, and at that point
+the algorithm stops. Thus, if there is more than one possible match, this
+algorithm returns the first one that it finds. Whether this is the shortest,
+the longest, or some intermediate length depends on the way the greedy and
+ungreedy repetition quantifiers are specified in the pattern.
+.P
+Because it ends up with a single path through the tree, it is relatively
+straightforward for this algorithm to keep track of the substrings that are
+matched by portions of the pattern in parentheses. This provides support for
+capturing parentheses and back references.
+.
+.
+.SH "THE ALTERNATIVE MATCHING ALGORITHM"
+.rs
+.sp
+This algorithm conducts a breadth-first search of the tree. Starting from the
+first matching point in the subject, it scans the subject string from left to
+right, once, character by character, and as it does this, it remembers all the
+paths through the tree that represent valid matches. In Friedl's terminology,
+this is a kind of "DFA algorithm", though it is not implemented as a
+traditional finite state machine (it keeps multiple states active
+simultaneously).
+.P
+Although the general principle of this matching algorithm is that it scans the
+subject string only once, without backtracking, there is one exception: when a
+lookaround assertion is encountered, the characters following or preceding the
+current point have to be independently inspected.
+.P
+The scan continues until either the end of the subject is reached, or there are
+no more unterminated paths. At this point, terminated paths represent the
+different matching possibilities (if there are none, the match has failed).
+Thus, if there is more than one possible match, this algorithm finds all of
+them, and in particular, it finds the longest. The matches are returned in
+decreasing order of length. There is an option to stop the algorithm after the
+first match (which is necessarily the shortest) is found.
+.P
+Note that all the matches that are found start at the same point in the
+subject. If the pattern
+.sp
+ cat(er(pillar)?)?
+.sp
+is matched against the string "the caterpillar catchment", the result is the
+three strings "caterpillar", "cater", and "cat" that start at the fifth
+character of the subject. The algorithm does not automatically move on to find
+matches that start at later positions.
+.P
+PCRE2's "auto-possessification" optimization usually applies to character
+repeats at the end of a pattern (as well as internally). For example, the
+pattern "a\ed+" is compiled as if it were "a\ed++" because there is no point
+even considering the possibility of backtracking into the repeated digits. For
+DFA matching, this means that only one possible match is found. If you really
+do want multiple matches in such cases, either use an ungreedy repeat
+("a\ed+?") or set the PCRE2_NO_AUTO_POSSESS option when compiling.
+.P
+There are a number of features of PCRE2 regular expressions that are not
+supported by the alternative matching algorithm. They are as follows:
+.P
+1. Because the algorithm finds all possible matches, the greedy or ungreedy
+nature of repetition quantifiers is not relevant (though it may affect
+auto-possessification, as just described). During matching, greedy and ungreedy
+quantifiers are treated in exactly the same way. However, possessive
+quantifiers can make a difference when what follows could also match what is
+quantified, for example in a pattern like this:
+.sp
+ ^a++\ew!
+.sp
+This pattern matches "aaab!" but not "aaa!", which would be matched by a
+non-possessive quantifier. Similarly, if an atomic group is present, it is
+matched as if it were a standalone pattern at the current point, and the
+longest match is then "locked in" for the rest of the overall pattern.
+.P
+2. When dealing with multiple paths through the tree simultaneously, it is not
+straightforward to keep track of captured substrings for the different matching
+possibilities, and PCRE2's implementation of this algorithm does not attempt to
+do this. This means that no captured substrings are available.
+.P
+3. Because no substrings are captured, back references within the pattern are
+not supported, and cause errors if encountered.
+.P
+4. For the same reason, conditional expressions that use a backreference as the
+condition or test for a specific group recursion are not supported.
+.P
+5. Because many paths through the tree may be active, the \eK escape sequence,
+which resets the start of the match when encountered (but may be on some paths
+and not on others), is not supported. It causes an error if encountered.
+.P
+6. Callouts are supported, but the value of the \fIcapture_top\fP field is
+always 1, and the value of the \fIcapture_last\fP field is always 0.
+.P
+7. The \eC escape sequence, which (in the standard algorithm) always matches a
+single code unit, even in a UTF mode, is not supported in these modes, because
+the alternative algorithm moves through the subject string one character (not
+code unit) at a time, for all active paths through the tree.
+.P
+8. Except for (*FAIL), the backtracking control verbs such as (*PRUNE) are not
+supported. (*FAIL) is supported, and behaves like a failing negative assertion.
+.
+.
+.SH "ADVANTAGES OF THE ALTERNATIVE ALGORITHM"
+.rs
+.sp
+Using the alternative matching algorithm provides the following advantages:
+.P
+1. All possible matches (at a single point in the subject) are automatically
+found, and in particular, the longest match is found. To find more than one
+match using the standard algorithm, you have to do kludgy things with
+callouts.
+.P
+2. Because the alternative algorithm scans the subject string just once, and
+never needs to backtrack (except for lookbehinds), it is possible to pass very
+long subject strings to the matching function in several pieces, checking for
+partial matching each time. Although it is also possible to do multi-segment
+matching using the standard algorithm, by retaining partially matched
+substrings, it is more complicated. The
+.\" HREF
+\fBpcre2partial\fP
+.\"
+documentation gives details of partial matching and discusses multi-segment
+matching.
+.
+.
+.SH "DISADVANTAGES OF THE ALTERNATIVE ALGORITHM"
+.rs
+.sp
+The alternative algorithm suffers from a number of disadvantages:
+.P
+1. It is substantially slower than the standard algorithm. This is partly
+because it has to search for all possible matches, but is also because it is
+less susceptible to optimization.
+.P
+2. Capturing parentheses and back references are not supported.
+.P
+3. Although atomic groups are supported, their use does not provide the
+performance advantage that it does for the standard algorithm.

+.TH PCRE2PARTIAL 3 "22 December 2014" "PCRE2 10.00"
+.SH NAME
+PCRE2 - Perl-compatible regular expressions
+.SH "PARTIAL MATCHING IN PCRE2"
+.rs
+.sp
+In normal use of PCRE2, if the subject string that is passed to a matching
+function matches as far as it goes, but is too short to match the entire
+pattern, PCRE2_ERROR_NOMATCH is returned. There are circumstances where it
+might be helpful to distinguish this case from other cases in which there is no
+match.
+.P
+Consider, for example, an application where a human is required to type in data
+for a field with specific formatting requirements. An example might be a date
+in the form \fIddmmmyy\fP, defined by this pattern:
+.sp
+ ^\ed?\ed(jan|feb|mar|apr|may|jun|jul|aug|sep|oct|nov|dec)\ed\ed$
+.sp
+If the application sees the user's keystrokes one by one, and can check that
+what has been typed so far is potentially valid, it is able to raise an error
+as soon as a mistake is made, by beeping and not reflecting the character that
+has been typed, for example. This immediate feedback is likely to be a better
+user interface than a check that is delayed until the entire string has been
+entered. Partial matching can also be useful when the subject string is very
+long and is not all available at once.
+.P
+PCRE2 supports partial matching by means of the PCRE2_PARTIAL_SOFT and
+PCRE2_PARTIAL_HARD options, which can be set when calling a matching function.
+The difference between the two options is whether or not a partial match is
+preferred to an alternative complete match, though the details differ between
+the two types of matching function. If both options are set, PCRE2_PARTIAL_HARD
+takes precedence.
+.P
+If you want to use partial matching with just-in-time optimized code, you must
+call \fBpcre2_jit_compile()\fP with one or both of these options:
+.sp
+ PCRE2_JIT_PARTIAL_SOFT
+ PCRE2_JIT_PARTIAL_HARD
+.sp
+PCRE2_JIT_COMPLETE should also be set if you are going to run non-partial
+matches on the same pattern. If the appropriate JIT mode has not been compiled,
+interpretive matching code is used.
+.P
+Setting a partial matching option disables two of PCRE2's standard
+optimizations. PCRE2 remembers the last literal code unit in a pattern, and
+abandons matching immediately if it is not present in the subject string. This
+optimization cannot be used for a subject string that might match only
+partially. PCRE2 also knows the minimum length of a matching string, and does
+not bother to run the matching function on shorter strings. This optimization
+is also disabled for partial matching.
+.
+.
+.SH "PARTIAL MATCHING USING pcre2_match()"
+.rs
+.sp
+A partial match occurs during a call to \fBpcre2_match()\fP when the end of the
+subject string is reached successfully, but matching cannot continue because
+more characters are needed. However, at least one character in the subject must
+have been inspected. This character need not form part of the final matched
+string; lookbehind assertions and the \eK escape sequence provide ways of
+inspecting characters before the start of a matched string. The requirement for
+inspecting at least one character exists because an empty string can always be
+matched; without such a restriction there would always be a partial match of an
+empty string at the end of the subject.
+.P
+When a partial match is returned, the first two elements in the ovector point
+to the portion of the subject that was matched, but the values in the rest of
+the ovector are undefined. The appearance of \eK in the pattern has no effect
+for a partial match. Consider this pattern:
+.sp
+ /abc\eK123/
+.sp
+If it is matched against "456abc123xyz" the result is a complete match, and the
+ovector defines the matched string as "123", because \eK resets the "start of
+match" point. However, if a partial match is requested and the subject string
+is "456abc12", a partial match is found for the string "abc12", because all
+these characters are needed for a subsequent re-match with additional
+characters.
+.P
+What happens when a partial match is identified depends on which of the two
+partial matching options are set.
+.
+.
+.SS "PCRE2_PARTIAL_SOFT WITH pcre2_match()"
+.rs
+.sp
+If PCRE2_PARTIAL_SOFT is set when \fBpcre2_match()\fP identifies a partial
+match, the partial match is remembered, but matching continues as normal, and
+other alternatives in the pattern are tried. If no complete match can be found,
+PCRE2_ERROR_PARTIAL is returned instead of PCRE2_ERROR_NOMATCH.
+.P
+This option is "soft" because it prefers a complete match over a partial match.
+All the various matching items in a pattern behave as if the subject string is
+potentially complete. For example, \ez, \eZ, and $ match at the end of the
+subject, as normal, and for \eb and \eB the end of the subject is treated as a
+non-alphanumeric.
+.P
+If there is more than one partial match, the first one that was found provides
+the data that is returned. Consider this pattern:
+.sp
+ /123\ew+X|dogY/
+.sp
+If this is matched against the subject string "abc123dog", both
+alternatives fail to match, but the end of the subject is reached during
+matching, so PCRE2_ERROR_PARTIAL is returned. The offsets are set to 3 and 9,
+identifying "123dog" as the first partial match that was found. (In this
+example, there are two partial matches, because "dog" on its own partially
+matches the second alternative.)
+.
+.
+.SS "PCRE2_PARTIAL_HARD WITH pcre2_match()"
+.rs
+.sp
+If PCRE2_PARTIAL_HARD is set for \fBpcre2_match()\fP, PCRE2_ERROR_PARTIAL is
+returned as soon as a partial match is found, without continuing to search for
+possible complete matches. This option is "hard" because it prefers an earlier
+partial match over a later complete match. For this reason, the assumption is
+made that the end of the supplied subject string may not be the true end of the
+available data, and so, if \ez, \eZ, \eb, \eB, or $ are encountered at the end
+of the subject, the result is PCRE2_ERROR_PARTIAL, provided that at least one
+character in the subject has been inspected.
+.
+.
+.SS "Comparing hard and soft partial matching"
+.rs
+.sp
+The difference between the two partial matching options can be illustrated by a
+pattern such as:
+.sp
+ /dog(sbody)?/
+.sp
+This matches either "dog" or "dogsbody", greedily (that is, it prefers the
+longer string if possible). If it is matched against the string "dog" with
+PCRE2_PARTIAL_SOFT, it yields a complete match for "dog". However, if
+PCRE2_PARTIAL_HARD is set, the result is PCRE2_ERROR_PARTIAL. On the other
+hand, if the pattern is made ungreedy the result is different:
+.sp
+ /dog(sbody)??/
+.sp
+In this case the result is always a complete match because that is found first,
+and matching never continues after finding a complete match. It might be easier
+to follow this explanation by thinking of the two patterns like this:
+.sp
+ /dog(sbody)?/ is the same as /dogsbody|dog/
+ /dog(sbody)??/ is the same as /dog|dogsbody/
+.sp
+The second pattern will never match "dogsbody", because it will always find the
+shorter match first.
+.
+.
+.SH "PARTIAL MATCHING USING pcre2_dfa_match()"
+.rs
+.sp
+The DFA functions move along the subject string character by character, without
+backtracking, searching for all possible matches simultaneously. If the end of
+the subject is reached before the end of the pattern, there is the possibility
+of a partial match, again provided that at least one character has been
+inspected.
+.P
+When PCRE2_PARTIAL_SOFT is set, PCRE2_ERROR_PARTIAL is returned only if there
+have been no complete matches. Otherwise, the complete matches are returned.
+However, if PCRE2_PARTIAL_HARD is set, a partial match takes precedence over
+any complete matches. The portion of the string that was matched when the
+longest partial match was found is set as the first matching string.
+.P
+Because the DFA functions always search for all possible matches, and there is
+no difference between greedy and ungreedy repetition, their behaviour is
+different from the standard functions when PCRE2_PARTIAL_HARD is set. Consider
+the string "dog" matched against the ungreedy pattern shown above:
+.sp
+ /dog(sbody)??/
+.sp
+Whereas the standard function stops as soon as it finds the complete match for
+"dog", the DFA function also finds the partial match for "dogsbody", and so
+returns that when PCRE2_PARTIAL_HARD is set.
+.
+.
+.SH "PARTIAL MATCHING AND WORD BOUNDARIES"
+.rs
+.sp
+If a pattern ends with one of sequences \eb or \eB, which test for word
+boundaries, partial matching with PCRE2_PARTIAL_SOFT can give counter-intuitive
+results. Consider this pattern:
+.sp
+ /\ebcat\eb/
+.sp
+This matches "cat", provided there is a word boundary at either end. If the
+subject string is "the cat", the comparison of the final "t" with a following
+character cannot take place, so a partial match is found. However, normal
+matching carries on, and \eb matches at the end of the subject when the last
+character is a letter, so a complete match is found. The result, therefore, is
+\fInot\fP PCRE2_ERROR_PARTIAL. Using PCRE2_PARTIAL_HARD in this case does yield
+PCRE2_ERROR_PARTIAL, because then the partial match takes precedence.
+.
+.
+.SH "EXAMPLE OF PARTIAL MATCHING USING PCRE2TEST"
+.rs
+.sp
+If the \fBpartial_soft\fP (or \fBps\fP) modifier is present on a
+\fBpcre2test\fP data line, the PCRE2_PARTIAL_SOFT option is used for the match.
+Here is a run of \fBpcre2test\fP that uses the date example quoted above:
+.sp
+ re> /^\ed?\ed(jan|feb|mar|apr|may|jun|jul|aug|sep|oct|nov|dec)\ed\ed$/
+ data> 25jun04\e=ps
+ 0: 25jun04
+ 1: jun
+ data> 25dec3\e=ps
+ Partial match: 23dec3
+ data> 3ju\e=ps
+ Partial match: 3ju
+ data> 3juj\e=ps
+ No match
+ data> j\e=ps
+ No match
+.sp
+The first data string is matched completely, so \fBpcre2test\fP shows the
+matched substrings. The remaining four strings do not match the complete
+pattern, but the first two are partial matches. Similar output is obtained
+if DFA matching is used.
+.P
+If the \fBpartial_hard\fP (or \fBph\fP) modifier is present on a
+\fBpcre2test\fP data line, the PCRE2_PARTIAL_HARD option is set for the match.
+.
+.
+.SH "MULTI-SEGMENT MATCHING WITH pcre2_dfa_match()"
+.rs
+.sp
+When a partial match has been found using a DFA matching function, it is
+possible to continue the match by providing additional subject data and calling
+the function again with the same compiled regular expression, this time setting
+the PCRE2_DFA_RESTART option. You must pass the same working space as before,
+because this is where details of the previous partial match are stored. Here is
+an example using \fBpcre2test\fP:
+.sp
+ re> /^\ed?\ed(jan|feb|mar|apr|may|jun|jul|aug|sep|oct|nov|dec)\ed\ed$/
+ data> 23ja\e=dfa,ps
+ Partial match: 23ja
+ data> n05\e=dfa,dfa_restart
+ 0: n05
+.sp
+The first call has "23ja" as the subject, and requests partial matching; the
+second call has "n05" as the subject for the continued (restarted) match.
+Notice that when the match is complete, only the last part is shown; PCRE2 does
+not retain the previously partially-matched string. It is up to the calling
+program to do that if it needs to.
+.P
+That means that, for an unanchored pattern, if a continued match fails, it is
+not possible to try again at a new starting point. All this facility is capable
+of doing is continuing with the previous match attempt. In the previous
+example, if the second set of data is "ug23" the result is no match, even
+though there would be a match for "aug23" if the entire string were given at
+once. Depending on the application, this may or may not be what you want.
+The only way to allow for starting again at the next character is to retain the
+matched part of the subject and try a new complete match.
+.P
+You can set the PCRE2_PARTIAL_SOFT or PCRE2_PARTIAL_HARD options with
+PCRE2_DFA_RESTART to continue partial matching over multiple segments. This
+facility can be used to pass very long subject strings to the DFA matching
+functions.
+.
+.
+.SH "MULTI-SEGMENT MATCHING WITH pcre2_match()"
+.rs
+.sp
+Unlike the DFA function, it is not possible to restart the previous match with
+a new segment of data when using \fBpcre2_match()\fP. Instead, new data must be
+added to the previous subject string, and the entire match re-run, starting
+from the point where the partial match occurred. Earlier data can be discarded.
+.P
+It is best to use PCRE2_PARTIAL_HARD in this situation, because it does not
+treat the end of a segment as the end of the subject when matching \ez, \eZ,
+\eb, \eB, and $. Consider an unanchored pattern that matches dates:
+.sp
+ re> /\ed?\ed(jan|feb|mar|apr|may|jun|jul|aug|sep|oct|nov|dec)\ed\ed/
+ data> The date is 23ja\e=ph
+ Partial match: 23ja
+.sp
+At this stage, an application could discard the text preceding "23ja", add on
+text from the next segment, and call the matching function again. Unlike the
+DFA matching function, the entire matching string must always be available,
+and the complete matching process occurs for each call, so more memory and more
+processing time is needed.
+.
+.
+.SH "ISSUES WITH MULTI-SEGMENT MATCHING"
+.rs
+.sp
+Certain types of pattern may give problems with multi-segment matching,
+whichever matching function is used.
+.P
+1. If the pattern contains a test for the beginning of a line, you need to pass
+the PCRE2_NOTBOL option when the subject string for any call does start at the
+beginning of a line. There is also a PCRE2_NOTEOL option, but in practice when
+doing multi-segment matching you should be using PCRE2_PARTIAL_HARD, which
+includes the effect of PCRE2_NOTEOL.
+.P
+2. If a pattern contains a lookbehind assertion, characters that precede the
+start of the partial match may have been inspected during the matching process.
+When using \fBpcre2_match()\fP, sufficient characters must be retained for the
+next match attempt. You can ensure that enough characters are retained by doing
+the following:
+.P
+Before doing any matching, find the length of the longest lookbehind in the
+pattern by calling \fBpcre2_pattern_info()\fP with the PCRE2_INFO_MAXLOOKBEHIND
+option. Note that the resulting count is in characters, not code units. After a
+partial match, moving back from the ovector[0] offset in the subject by the
+number of characters given for the maximum lookbehind gets you to the earliest
+character that must be retained. In a non-UTF or a 32-bit situation, moving
+back is just a subtraction, but in UTF-8 or UTF-16 you have to count characters
+while moving back through the code units.
+.P
+Characters before the point you have now reached can be discarded, and after
+the next segment has been added to what is retained, you should run the next
+match with the \fBstartoffset\fP argument set so that the match begins at the
+same point as before.
+.P
+For example, if the pattern "(?<=123)abc" is partially matched against the
+string "xx123ab", the ovector offsets are 5 and 7 ("ab"). The maximum
+lookbehind count is 3, so all characters before offset 2 can be discarded. The
+value of \fBstartoffset\fP for the next match should be 3. When \fBpcre2test\fP
+displays a partial match, it indicates the lookbehind characters with '<'
+characters:
+.sp
+ re> "(?<=123)abc"
+ data> xx123ab\e=ph
+ Partial match: 123ab
+ <<<
+.P
+3. Because a partial match must always contain at least one character, what
+might be considered a partial match of an empty string actually gives a "no
+match" result. For example:
+.sp
+ re> /c(?<=abc)x/
+ data> ab\e=ps
+ No match
+.sp
+If the next segment begins "cx", a match should be found, but this will only
+happen if characters from the previous segment are retained. For this reason, a
+"no match" result should be interpreted as "partial match of an empty string"
+when the pattern contains lookbehinds.
+.P
+4. Matching a subject string that is split into multiple segments may not
+always produce exactly the same result as matching over one single long string,
+especially when PCRE2_PARTIAL_SOFT is used. The section "Partial Matching and
+Word Boundaries" above describes an issue that arises if the pattern ends with
+\eb or \eB. Another kind of difference may occur when there are multiple
+matching possibilities, because (for PCRE2_PARTIAL_SOFT) a partial match result
+is given only when there are no completed matches. This means that as soon as
+the shortest match has been found, continuation to a new subject segment is no
+longer possible. Consider this \fBpcre2test\fP example:
+.sp
+ re> /dog(sbody)?/
+ data> dogsb\e=ps
+ 0: dog
+ data> do\e=ps,dfa
+ Partial match: do
+ data> gsb\e=ps,dfa,dfa_restart
+ 0: g
+ data> dogsbody\e=dfa
+ 0: dogsbody
+ 1: dog
+.sp
+The first data line passes the string "dogsb" to a standard matching function,
+setting the PCRE2_PARTIAL_SOFT option. Although the string is a partial match
+for "dogsbody", the result is not PCRE2_ERROR_PARTIAL, because the shorter
+string "dog" is a complete match. Similarly, when the subject is presented to
+a DFA matching function in several parts ("do" and "gsb" being the first two)
+the match stops when "dog" has been found, and it is not possible to continue.
+On the other hand, if "dogsbody" is presented as a single string, a DFA
+matching function finds both matches.
+.P
+Because of these problems, it is best to use PCRE2_PARTIAL_HARD when matching
+multi-segment data. The example above then behaves differently:
+.sp
+ re> /dog(sbody)?/
+ data> dogsb\e=ph
+ Partial match: dogsb
+ data> do\e=ps,dfa
+ Partial match: do
+ data> gsb\e=ph,dfa,dfa_restart
+ Partial match: gsb
+.sp
+5. Patterns that contain alternatives at the top level which do not all start
+with the same pattern item may not work as expected when PCRE2_DFA_RESTART is
+used. For example, consider this pattern:
+.sp
+ 1234|3789
+.sp
+If the first part of the subject is "ABC123", a partial match of the first
+alternative is found at offset 3. There is no partial match for the second
+alternative, because such a match does not start at the same point in the
+subject string. Attempting to continue with the string "7890" does not yield a
+match because only those alternatives that match at one point in the subject
+are remembered. The problem arises because the start of the second alternative
+matches within the first alternative. There is no problem with anchored
+patterns or patterns such as:
+.sp
+ 1234|ABCD
+.sp
+where no string can be a partial match for both alternatives. This is not a
+problem if a standard matching function is used, because the entire match has
+to be rerun each time:
+.sp
+ re> /1234|3789/
+ data> ABC123\e=ph
+ Partial match: 123
+ data> 1237890
+ 0: 3789
+.sp
+Of course, instead of using PCRE2_DFA_RESTART, the same technique of re-running
+the entire match can also be used with the DFA matching function. Another
+possibility is to work with two buffers. If a partial match at offset \fIn\fP
+in the first buffer is followed by "no match" when PCRE2_DFA_RESTART is used on
+the second buffer, you can then try a new match starting at offset \fIn+1\fP in
+the first buffer.

+.TH PCRE2PATTERN 3 "13 November 2015" "PCRE2 10.21"
+.SH NAME
+PCRE2 - Perl-compatible regular expressions (revised API)
+.SH "PCRE2 REGULAR EXPRESSION DETAILS"
+.rs
+.sp
+The syntax and semantics of the regular expressions that are supported by PCRE2
+are described in detail below. There is a quick-reference syntax summary in the
+.\" HREF
+\fBpcre2syntax\fP
+.\"
+page. PCRE2 tries to match Perl syntax and semantics as closely as it can.
+PCRE2 also supports some alternative regular expression syntax (which does not
+conflict with the Perl syntax) in order to provide some compatibility with
+regular expressions in Python, .NET, and Oniguruma.
+.P
+Perl's regular expressions are described in its own documentation, and regular
+expressions in general are covered in a number of books, some of which have
+copious examples. Jeffrey Friedl's "Mastering Regular Expressions", published
+by O'Reilly, covers regular expressions in great detail. This description of
+PCRE2's regular expressions is intended as reference material.
+.P
+This document discusses the patterns that are supported by PCRE2 when its main
+matching function, \fBpcre2_match()\fP, is used. PCRE2 also has an alternative
+matching function, \fBpcre2_dfa_match()\fP, which matches using a different
+algorithm that is not Perl-compatible. Some of the features discussed below are
+not available when DFA matching is used. The advantages and disadvantages of
+the alternative function, and how it differs from the normal function, are
+discussed in the
+.\" HREF
+\fBpcre2matching\fP
+.\"
+page.
+.
+.
+.SH "SPECIAL START-OF-PATTERN ITEMS"
+.rs
+.sp
+A number of options that can be passed to \fBpcre2_compile()\fP can also be set
+by special items at the start of a pattern. These are not Perl-compatible, but
+are provided to make these options accessible to pattern writers who are not
+able to change the program that processes the pattern. Any number of these
+items may appear, but they must all be together right at the start of the
+pattern string, and the letters must be in upper case.
+.
+.
+.SS "UTF support"
+.rs
+.sp
+In the 8-bit and 16-bit PCRE2 libraries, characters may be coded either as
+single code units, or as multiple UTF-8 or UTF-16 code units. UTF-32 can be
+specified for the 32-bit library, in which case it constrains the character
+values to valid Unicode code points. To process UTF strings, PCRE2 must be
+built to include Unicode support (which is the default). When using UTF strings
+you must either call the compiling function with the PCRE2_UTF option, or the
+pattern must start with the special sequence (*UTF), which is equivalent to
+setting the relevant option. How setting a UTF mode affects pattern matching is
+mentioned in several places below. There is also a summary of features in the
+.\" HREF
+\fBpcre2unicode\fP
+.\"
+page.
+.P
+Some applications that allow their users to supply patterns may wish to
+restrict them to non-UTF data for security reasons. If the PCRE2_NEVER_UTF
+option is passed to \fBpcre2_compile()\fP, (*UTF) is not allowed, and its
+appearance in a pattern causes an error.
+.
+.
+.SS "Unicode property support"
+.rs
+.sp
+Another special sequence that may appear at the start of a pattern is (*UCP).

+Some applications that allow their users to supply patterns may wish to

+.sp
+The caller of \fBpcre2_match()\fP can set a limit on the number of times the

+recursive calls. These facilities are provided to catch runaway matches that
+are provoked by patterns with huge matching trees (a typical example is a
+pattern with nested unlimited repeats) and to avoid running out of system stack
+by too much recursion. When one of these limits is reached, \fBpcre2_match()\fP
+gives an error return. The limits can also be set by items at the start of the
+pattern of the form
+.sp
+ (*LIMIT_MATCH=d)

+.sp
+where d is any number of decimal digits. However, the value of the setting must
+be less than the value set (or defaulted) by the caller of \fBpcre2_match()\fP

+limits set by the programmer, but not raise them. If there is more than one
+setting of one of these limits, the lower value is used.

+.\" HTML <a name="newlines"></a>
+.SS "Newline conventions"
+.rs
+.sp
+PCRE2 supports five different conventions for indicating line breaks in
+strings: a single CR (carriage return) character, a single LF (linefeed)
+character, the two-character sequence CRLF, any of the three preceding, or any
+Unicode newline sequence. The
+.\" HREF
+\fBpcre2api\fP
+.\"
+page has
+.\" HTML <a href="pcre2api.html#newlines">
+.\" </a>
+further discussion
+.\"
+about newlines, and shows how to set the newline convention when calling
+\fBpcre2_compile()\fP.
+.P
+It is also possible to specify a newline convention by starting a pattern
+string with one of the following five sequences:
+.sp
+ (*CR) carriage return
+ (*LF) linefeed
+ (*CRLF) carriage return, followed by linefeed
+ (*ANYCRLF) any of the three above
+ (*ANY) all Unicode newline sequences
+.sp
+These override the default and the options given to the compiling function. For
+example, on a Unix system where LF is the default newline sequence, the pattern
+.sp
+ (*CR)a.b
+.sp
+changes the convention to CR. That pattern matches "a\enb" because LF is no
+longer a newline. If more than one of these settings is present, the last one
+is used.
+.P
+The newline convention affects where the circumflex and dollar assertions are
+true. It also affects the interpretation of the dot metacharacter when
+PCRE2_DOTALL is not set, and the behaviour of \eN. However, it does not affect
+what the \eR escape sequence matches. By default, this is any Unicode newline
+sequence, for Perl compatibility. However, this can be changed; see the
+description of \eR in the section entitled
+.\" HTML <a href="#newlineseq">

+convention.
+.
+.

+It is possible to restrict \eR to match only CR, LF, or CRLF (instead of the

+at compile time. This effect can also be achieved by starting a pattern with
+(*BSR_ANYCRLF). For completeness, (*BSR_UNICODE) is also recognized,
+corresponding to PCRE2_BSR_UNICODE.
+.
+.
+.SH "EBCDIC CHARACTER CODES"
+.rs
+.sp
+PCRE2 can be compiled to run in an environment that uses EBCDIC as its
+character code rather than ASCII or Unicode (typically a mainframe system). In
+the sections below, character code values are ASCII or Unicode; in an EBCDIC
+environment these characters may have different code values, and there are no
+code points greater than 255.
+.
+.
+.SH "CHARACTERS AND METACHARACTERS"
+.rs
+.sp
+A regular expression is a pattern that is matched against a subject string from
+left to right. Most characters stand for themselves in a pattern, and match the
+corresponding characters in the subject. As a trivial example, the pattern
+.sp
+ The quick brown fox
+.sp
+matches a portion of a subject string that is identical to itself. When
+caseless matching is specified (the PCRE2_CASELESS option), letters are matched
+independently of case.
+.P
+The power of regular expressions comes from the ability to include alternatives
+and repetitions in the pattern. These are encoded in the pattern by the use of
+\fImetacharacters\fP, which do not stand for themselves but instead are
+interpreted in some special way.
+.P
+There are two different sets of metacharacters: those that are recognized
+anywhere in the pattern except within square brackets, and those that are
+recognized within square brackets. Outside square brackets, the metacharacters
+are as follows:
+.sp
+ \e general escape character with several uses
+ ^ assert start of string (or line, in multiline mode)
+ $ assert end of string (or line, in multiline mode)
+ . match any character except newline (by default)
+ [ start character class definition
+ | start of alternative branch
+ ( start subpattern
+ ) end subpattern
+ ? extends the meaning of (
+ also 0 or 1 quantifier
+ also quantifier minimizer
+ * 0 or more quantifier
+ + 1 or more quantifier
+ also "possessive quantifier"
+ { start min/max quantifier
+.sp
+Part of a pattern that is in square brackets is called a "character class". In
+a character class the only metacharacters are:
+.sp
+ \e general escape character
+ ^ negate the class, but only if the first character
+ - indicates character range
+.\" JOIN
+ [ POSIX character class (only if followed by POSIX
+ syntax)
+ ] terminates the character class
+.sp
+The following sections describe the use of each of the metacharacters.
+.
+.
+.SH BACKSLASH
+.rs
+.sp
+The backslash character has several uses. Firstly, if it is followed by a
+character that is not a number or a letter, it takes away any special meaning
+that character may have. This use of backslash as an escape character applies
+both inside and outside character classes.
+.P
+For example, if you want to match a * character, you write \e* in the pattern.
+This escaping action applies whether or not the following character would
+otherwise be interpreted as a metacharacter, so it is always safe to precede a
+non-alphanumeric with backslash to specify that it stands for itself. In
+particular, if you want to match a backslash, you write \e\e.
+.P
+In a UTF mode, only ASCII numbers and letters have any special meaning after a
+backslash. All other characters (in particular, those whose codepoints are
+greater than 127) are treated as literals.
+.P
+If a pattern is compiled with the PCRE2_EXTENDED option, most white space in
+the pattern (other than in a character class), and characters between a #
+outside a character class and the next newline, inclusive, are ignored. An
+escaping backslash can be used to include a white space or # character as part
+of the pattern.
+.P
+If you want to remove the special meaning from a sequence of characters, you
+can do so by putting them between \eQ and \eE. This is different from Perl in
+that $ and @ are handled as literals in \eQ...\eE sequences in PCRE2, whereas
+in Perl, $ and @ cause variable interpolation. Note the following examples:
+.sp
+ Pattern PCRE2 matches Perl matches
+.sp
+.\" JOIN
+ \eQabc$xyz\eE abc$xyz abc followed by the
+ contents of $xyz
+ \eQabc\e$xyz\eE abc\e$xyz abc\e$xyz
+ \eQabc\eE\e$\eQxyz\eE abc$xyz abc$xyz
+.sp
+The \eQ...\eE sequence is recognized both inside and outside character classes.
+An isolated \eE that is not preceded by \eQ is ignored. If \eQ is not followed
+by \eE later in the pattern, the literal interpretation continues to the end of
+the pattern (that is, \eE is assumed at the end). If the isolated \eQ is inside
+a character class, this causes an error, because the character class is not
+terminated.
+.
+.
+.\" HTML <a name="digitsafterbackslash"></a>
+.SS "Non-printing characters"
+.rs
+.sp
+A second use of backslash provides a way of encoding non-printing characters
+in patterns in a visible manner. There is no restriction on the appearance of
+non-printing characters in a pattern, but when a pattern is being prepared by
+text editing, it is often easier to use one of the following escape sequences
+than the binary character it represents. In an ASCII or Unicode environment,
+these escapes are as follows:
+.sp
+ \ea alarm, that is, the BEL character (hex 07)
+ \ecx "control-x", where x is any printable ASCII character
+ \ee escape (hex 1B)
+ \ef form feed (hex 0C)
+ \en linefeed (hex 0A)
+ \er carriage return (hex 0D)
+ \et tab (hex 09)
+ \e0dd character with octal code 0dd
+ \eddd character with octal code ddd, or back reference
+ \eo{ddd..} character with octal code ddd..
+ \exhh character with hex code hh
+ \ex{hhh..} character with hex code hhh.. (default mode)
+ \euhhhh character with hex code hhhh (when PCRE2_ALT_BSUX is set)
+.sp
+The precise effect of \ecx on ASCII characters is as follows: if x is a lower
+case letter, it is converted to upper case. Then bit 6 of the character (hex
+40) is inverted. Thus \ecA to \ecZ become hex 01 to hex 1A (A is 41, Z is 5A),
+but \ec{ becomes hex 3B ({ is 7B), and \ec; becomes hex 7B (; is 3B). If the
+code unit following \ec has a value less than 32 or greater than 126, a
+compile-time error occurs. This locks out non-printable ASCII characters in all
+modes.
+.P
+When PCRE2 is compiled in EBCDIC mode, \ea, \ee, \ef, \en, \er, and \et
+generate the appropriate EBCDIC code values. The \ec escape is processed
+as specified for Perl in the \fBperlebcdic\fP document. The only characters
+that are allowed after \ec are A-Z, a-z, or one of @, [, \e, ], ^, _, or ?. Any
+other character provokes a compile-time error. The sequence \e@ encodes
+character code 0; the letters (in either case) encode characters 1-26 (hex 01
+to hex 1A); [, \e, ], ^, and _ encode characters 27-31 (hex 1B to hex 1F), and
+\e? becomes either 255 (hex FF) or 95 (hex 5F).
+.P
+Thus, apart from \e?, these escapes generate the same character code values as
+they do in an ASCII environment, though the meanings of the values mostly
+differ. For example, \eG always generates code value 7, which is BEL in ASCII
+but DEL in EBCDIC.
+.P
+The sequence \e? generates DEL (127, hex 7F) in an ASCII environment, but
+because 127 is not a control character in EBCDIC, Perl makes it generate the
+APC character. Unfortunately, there are several variants of EBCDIC. In most of
+them the APC character has the value 255 (hex FF), but in the one Perl calls
+POSIX-BC its value is 95 (hex 5F). If certain other characters have POSIX-BC
+values, PCRE2 makes \e? generate 95; otherwise it generates 255.
+.P
+After \e0 up to two further octal digits are read. If there are fewer than two
+digits, just those that are present are used. Thus the sequence \e0\ex\e015
+specifies two binary zeros followed by a CR character (code value 13). Make
+sure you supply two digits after the initial zero if the pattern character that
+follows is itself an octal digit.
+.P
+The escape \eo must be followed by a sequence of octal digits, enclosed in
+braces. An error occurs if this is not the case. This escape is a recent
+addition to Perl; it provides way of specifying character code points as octal
+numbers greater than 0777, and it also allows octal numbers and back references
+to be unambiguously specified.
+.P
+For greater clarity and unambiguity, it is best to avoid following \e by a
+digit greater than zero. Instead, use \eo{} or \ex{} to specify character
+numbers, and \eg{} to specify back references. The following paragraphs
+describe the old, ambiguous syntax.
+.P
+The handling of a backslash followed by a digit other than 0 is complicated,
+and Perl has changed over time, causing PCRE2 also to change.
+.P
+Outside a character class, PCRE2 reads the digit and any following digits as a
+decimal number. If the number is less than 10, begins with the digit 8 or 9, or
+if there are at least that many previous capturing left parentheses in the
+expression, the entire sequence is taken as a \fIback reference\fP. A
+description of how this works is given
+.\" HTML <a href="#backreferences">
+.\" </a>
+later,
+.\"
+following the discussion of
+.\" HTML <a href="#subpattern">
+.\" </a>
+parenthesized subpatterns.
+.\"
+Otherwise, up to three octal digits are read to form a character code.
+.P
+Inside a character class, PCRE2 handles \e8 and \e9 as the literal characters
+"8" and "9", and otherwise reads up to three octal digits following the
+backslash, using them to generate a data character. Any subsequent digits stand
+for themselves. For example, outside a character class:
+.sp
+ \e040 is another way of writing an ASCII space
+.\" JOIN
+ \e40 is the same, provided there are fewer than 40
+ previous capturing subpatterns
+ \e7 is always a back reference
+.\" JOIN
+ \e11 might be a back reference, or another way of
+ writing a tab
+ \e011 is always a tab
+ \e0113 is a tab followed by the character "3"
+.\" JOIN
+ \e113 might be a back reference, otherwise the
+ character with octal code 113
+.\" JOIN
+ \e377 might be a back reference, otherwise
+ the value 255 (decimal)
+.\" JOIN
+ \e81 is always a back reference
+.sp
+Note that octal values of 100 or greater that are specified using this syntax
+must not be introduced by a leading zero, because no more than three octal
+digits are ever read.
+.P
+By default, after \ex that is not followed by {, from zero to two hexadecimal
+digits are read (letters can be in upper or lower case). Any number of
+hexadecimal digits may appear between \ex{ and }. If a character other than
+a hexadecimal digit appears between \ex{ and }, or if there is no terminating
+}, an error occurs.
+.P
+If the PCRE2_ALT_BSUX option is set, the interpretation of \ex is as just
+described only when it is followed by two hexadecimal digits. Otherwise, it
+matches a literal "x" character. In this mode mode, support for code points
+greater than 256 is provided by \eu, which must be followed by four hexadecimal
+digits; otherwise it matches a literal "u" character.
+.P
+Characters whose value is less than 256 can be defined by either of the two
+syntaxes for \ex (or by \eu in PCRE2_ALT_BSUX mode). There is no difference in
+the way they are handled. For example, \exdc is exactly the same as \ex{dc} (or
+\eu00dc in PCRE2_ALT_BSUX mode).
+.
+.
+.SS "Constraints on character values"
+.rs
+.sp
+Characters that are specified using octal or hexadecimal numbers are
+limited to certain values, as follows:
+.sp
+ 8-bit non-UTF mode less than 0x100
+ 8-bit UTF-8 mode less than 0x10ffff and a valid codepoint
+ 16-bit non-UTF mode less than 0x10000

+.sp
+Invalid Unicode codepoints are the range 0xd800 to 0xdfff (the so-called
+"surrogate" codepoints), and 0xffef.
+.
+.
+.SS "Escape sequences in character classes"
+.rs
+.sp
+All the sequences that define a single character value can be used both inside
+and outside character classes. In addition, inside a character class, \eb is
+interpreted as the backspace character (hex 08).
+.P
+\eN is not allowed in a character class. \eB, \eR, and \eX are not special
+inside a character class. Like other unrecognized alphabetic escape sequences,
+they cause an error. Outside a character class, these sequences have different
+meanings.
+.
+.
+.SS "Unsupported escape sequences"
+.rs
+.sp
+In Perl, the sequences \el, \eL, \eu, and \eU are recognized by its string
+handler and used to modify the case of following characters. By default, PCRE2
+does not support these escape sequences. However, if the PCRE2_ALT_BSUX option
+is set, \eU matches a "U" character, and \eu can be used to define a character
+by code point, as described in the previous section.
+.
+.
+.SS "Absolute and relative back references"
+.rs
+.sp
+The sequence \eg followed by an unsigned or a negative number, optionally

+ \eh any horizontal white space character
+ \eH any character that is not a horizontal white space character
+ \es any white space character
+ \eS any character that is not a white space character
+ \ev any vertical white space character
+ \eV any character that is not a vertical white space character
+ \ew any "word" character
+ \eW any "non-word" character

+.\" </a>
+the "." metacharacter
+.\"
+when PCRE2_DOTALL is not set. Perl also uses \eN to match characters by name;
+PCRE2 does not support this.
+.P
+Each pair of lower and upper case escape sequences partitions the complete set
+of characters into two disjoint sets. Any given character matches one, and only
+one, of each pair. The sequences can appear both inside and outside character
+classes. They each match one character of the appropriate type. If the current
+matching point is at the end of the subject string, all of them fail, because
+there is no character to match.
+.P
+The default \es characters are HT (9), LF (10), VT (11), FF (12), CR (13), and
+space (32), which are defined as white space in the "C" locale. This list may
+vary if locale-specific matching is taking place. For example, in some locales
+the "non-breaking space" character (\exA0) is recognized as white space, and in
+others the VT character is not.
+.P
+A "word" character is an underscore or any character that is a letter or digit.
+By default, the definition of letters and digits is controlled by PCRE2's
+low-valued character tables, and may vary if locale-specific matching is taking
+place (see
+.\" HTML <a href="pcre2api.html#localesupport">
+.\" </a>
+"Locale support"
+.\"
+in the
+.\" HREF
+\fBpcre2api\fP
+.\"
+page). For example, in a French locale such as "fr_FR" in Unix-like systems,
+or "french" in Windows, some character codes greater than 127 are used for
+accented letters, and these are then matched by \ew. The use of locales with
+Unicode is discouraged.
+.P
+By default, characters whose code points are greater than 127 never match \ed,
+\es, or \ew, and always match \eD, \eS, and \eW, although this may be different
+for characters in the range 128-255 when locale-specific matching is happening.
+These escape sequences retain their original meanings from before Unicode
+support was available, mainly for efficiency reasons. If the PCRE2_UCP option
+is set, the behaviour is changed so that Unicode properties are used to
+determine character types, as follows:
+.sp
+ \ed any character that matches \ep{Nd} (decimal digit)
+ \es any character that matches \ep{Z} or \eh or \ev
+ \ew any character that matches \ep{L} or \ep{N}, plus underscore
+.sp
+The upper case escapes match the inverse sets of characters. Note that \ed
+matches only decimal digits, whereas \ew matches any Unicode digit, as well as
+any Unicode letter, and underscore. Note also that PCRE2_UCP affects \eb, and
+\eB because they are defined in terms of \ew and \eW. Matching these sequences
+is noticeably slower when PCRE2_UCP is set.
+.P
+The sequences \eh, \eH, \ev, and \eV, in contrast to the other sequences, which
+match only ASCII characters by default, always match a specific list of code
+points, whether or not PCRE2_UCP is set. The horizontal space characters are:
+.sp
+ U+0009 Horizontal tab (HT)

+U+000B), FF (form feed, U+000C), CR (carriage return, U+000D), or NEL (next
+line, U+0085). Because this is an atomic group, the two-character sequence is
+treated as a single unit that cannot be split.
+.P
+In other modes, two additional characters whose codepoints are greater than 255
+are added: LS (line separator, U+2028) and PS (paragraph separator, U+2029).
+Unicode support is not needed for these characters to be recognized.
+.P
+It is possible to restrict \eR to match only CR, LF, or CRLF (instead of the
+complete set of Unicode line endings) by setting the option PCRE2_BSR_ANYCRLF
+at compile time. (BSR is an abbrevation for "backslash R".) This can be made
+the default when PCRE2 is built; if this is the case, the other behaviour can
+be requested via the PCRE2_BSR_UNICODE option. It is also possible to specify
+these settings by starting a pattern string with one of the following
+sequences:
+.sp
+ (*BSR_ANYCRLF) CR, LF, or CRLF only
+ (*BSR_UNICODE) any Unicode newline sequence
+.sp
+These override the default and the options given to the compiling function.
+Note that these special settings, which are not Perl-compatible, are recognized
+only at the very start of a pattern, and that they must be in upper case. If
+more than one of them is present, the last one is used. They can be combined
+with a change of newline convention; for example, a pattern can start with:
+.sp
+ (*ANY)(*BSR_ANYCRLF)

+ \eP{\fIxx\fP} a character without the \fIxx\fP property
+ \eX a Unicode extended grapheme cluster

+Other Perl properties such as "InMusicalSymbols" are not supported by PCRE2.

+.P
+Each character has exactly one Unicode general category property, specified by
+a two-letter abbreviation. For compatibility with Perl, negation can be
+specified by including a circumflex between the opening brace and the property
+name. For example, \ep{^Lu} is the same as \eP{Lu}.
+.P
+If only one letter is specified with \ep or \eP, it includes all the general
+category properties that start with that letter. In this case, in the absence
+of negation, the curly brackets in the escape sequence are optional; these two
+examples have the same effect:
+.sp
+ \ep{L}
+ \epL
+.sp
+The following general category property codes are supported:
+.sp
+ C Other
+ Cc Control
+ Cf Format
+ Cn Unassigned
+ Co Private use
+ Cs Surrogate
+.sp
+ L Letter
+ Ll Lower case letter
+ Lm Modifier letter

+ S Symbol
+ Sc Currency symbol
+ Sk Modifier symbol
+ Sm Mathematical symbol
+ So Other symbol
+.sp
+ Z Separator
+ Zl Line separator
+ Zp Paragraph separator
+ Zs Space separator
+.sp
+The special property L& is also supported: it matches a character that has
+the Lu, Ll, or Lt property, in other words, a letter that is not classified as
+a modifier or "other".
+.P
+The Cs (Surrogate) property applies only to characters in the range U+D800 to
+U+DFFF. Such characters are not valid in Unicode strings and so
+cannot be tested by PCRE2, unless UTF validity checking has been turned off
+(see the discussion of PCRE2_NO_UTF_CHECK in the
+.\" HREF
+\fBpcre2api\fP
+.\"
+page). Perl does not support the Cs property.
+.P
+The long synonyms for property names that Perl supports (such as \ep{Letter})
+are not supported by PCRE2, nor is it permitted to prefix any of these
+properties with "Is".
+.P
+No character that is in the Unicode table has the Cn (unassigned) property.
+Instead, this property is assumed for any code point that is not in the
+Unicode table.
+.P
+Specifying caseless matching does not affect these escape sequences. For
+example, \ep{Lu} always matches only upper case letters. This is different from
+the behaviour of current versions of Perl.
+.P
+Matching characters by Unicode property is not fast, because PCRE2 has to do a
+multistage table lookup in order to find a character's property. That is why
+the traditional escape sequences such as \ed and \ew do not use Unicode
+properties in PCRE2 by default, though you can make them do so by setting the
+PCRE2_UCP option or by starting the pattern with (*UCP).
+.
+.
+.SS Extended grapheme clusters
+.rs
+.sp
+The \eX escape matches any number of Unicode characters that form an "extended
+grapheme cluster", and treats the sequence as an atomic group
+.\" HTML <a href="#atomicgroup">
+.\" </a>
+(see below).
+.\"
+Unicode supports various kinds of composite character by giving each character
+a grapheme breaking property, and having rules that use these properties to
+define the boundaries of extended grapheme clusters. \eX always matches at
+least one character. Then it decides whether to add additional characters
+according to the following rules for ending a cluster:
+.P
+1. End at the end of the subject string.
+.P
+2. Do not end between CR and LF; otherwise end after any control character.
+.P
+3. Do not break Hangul (a Korean script) syllable sequences. Hangul characters
+are of five types: L, V, T, LV, and LVT. An L character may be followed by an
+L, V, LV, or LVT character; an LV or V character may be followed by a V or T
+character; an LVT or T character may be follwed only by a T character.
+.P
+4. Do not end before extending characters or spacing marks. Characters with
+the "mark" property always have the "extend" grapheme breaking property.
+.P
+5. Do not end after prepend characters.
+.P
+6. Otherwise, end the cluster.
+.
+.
+.\" HTML <a name="extraprops"></a>
+.SS PCRE2's additional properties
+.rs
+.sp
+As well as the standard Unicode properties described above, PCRE2 supports four
+more that make it possible to convert traditional escape sequences such as \ew
+and \es to use Unicode properties. PCRE2 uses these non-standard, non-Perl
+properties internally when PCRE2_UCP is set. However, they may also be used
+explicitly. These properties are:
+.sp
+ Xan Any alphanumeric character
+ Xps Any POSIX space character
+ Xsp Any Perl space character
+ Xwd Any Perl "word" character
+.sp
+Xan matches characters that have either the L (letter) or the N (number)
+property. Xps matches the characters tab, linefeed, vertical tab, form feed, or
+carriage return, and any other character that has the Z (separator) property.
+Xsp is the same as Xps; in PCRE1 it used to exclude vertical tab, for Perl
+compatibility, but Perl changed. Xwd matches the same characters as Xan, plus
+underscore.
+.P
+There is another non-standard property, Xuc, which matches any character that
+can be represented by a Universal Character Name in C++ and other programming
+languages. These are the characters $, @, ` (grave accent), and all characters
+with Unicode code points greater than or equal to U+00A0, except for the
+surrogates U+D800 to U+DFFF. Note that most base (ASCII) characters are
+excluded. (Universal Character Names are of the form \euHHHH or \eUHHHHHHHH
+where H is a hexadecimal digit. Note that the Xuc property does not match these
+sequences but the characters that they represent.)
+.
+.
+.\" HTML <a name="resetmatchstart"></a>
+.SS "Resetting the match start"
+.rs
+.sp
+The escape sequence \eK causes any previously matched characters not to be
+included in the final matched sequence. For example, the pattern:
+.sp
+ foo\eKbar
+.sp
+matches "foobar", but reports that it has matched "bar". This feature is
+similar to a lookbehind assertion
+.\" HTML <a href="#lookbehind">
+.\" </a>
+(described below).
+.\"
+However, in this case, the part of the subject before the real match does not
+have to be of fixed length, as lookbehind assertions do. The use of \eK does
+not interfere with the setting of
+.\" HTML <a href="#subpattern">
+.\" </a>
+captured substrings.
+.\"
+For example, when the pattern
+.sp
+ (foo)\eKbar
+.sp
+matches "foobar", the first substring is still set to "foo".
+.P
+Perl documents that the use of \eK within assertions is "not well defined". In
+PCRE2, \eK is acted upon when it occurs inside positive assertions, but is
+ignored in negative assertions. Note that when a pattern such as (?=ab\eK)
+matches, the reported start of the match can be greater than the end of the
+match.
+.
+.
+.\" HTML <a name="smallassertions"></a>
+.SS "Simple assertions"
+.rs
+.sp
+The final use of backslash is for certain simple assertions. An assertion
+specifies a condition that has to be met at a particular point in a match,
+without consuming any characters from the subject string. The use of
+subpatterns for more complicated assertions is described
+.\" HTML <a href="#bigassertions">
+.\" </a>
+below.
+.\"
+The backslashed assertions are:
+.sp
+ \eb matches at a word boundary
+ \eB matches when not at a word boundary
+ \eA matches at the start of the subject
+ \eZ matches at the end of the subject
+ also matches before a newline at the end of the subject
+ \ez matches only at the end of the subject
+ \eG matches at the first matching position in the subject
+.sp
+Inside a character class, \eb has a different meaning; it matches the backspace
+character. If any other of these assertions appears in a character class, an
+"invalid escape sequence" error is generated.
+.P
+A word boundary is a position in the subject string where the current character
+and the previous character do not both match \ew or \eW (i.e. one matches
+\ew and the other matches \eW), or the start or end of the string if the
+first or last character matches \ew, respectively. In a UTF mode, the meanings
+of \ew and \eW can be changed by setting the PCRE2_UCP option. When this is
+done, it also affects \eb and \eB. Neither PCRE2 nor Perl has a separate "start
+of word" or "end of word" metasequence. However, whatever follows \eb normally
+determines which it is. For example, the fragment \eba matches "a" at the start
+of a word.
+.P
+The \eA, \eZ, and \ez assertions differ from the traditional circumflex and
+dollar (described in the next section) in that they only ever match at the very
+start and end of the subject string, whatever options are set. Thus, they are
+independent of multiline mode. These three assertions are not affected by the
+PCRE2_NOTBOL or PCRE2_NOTEOL options, which affect only the behaviour of the
+circumflex and dollar metacharacters. However, if the \fIstartoffset\fP
+argument of \fBpcre2_match()\fP is non-zero, indicating that matching is to
+start at a point other than the beginning of the subject, \eA can never match.
+The difference between \eZ and \ez is that \eZ matches before a newline at the
+end of the string as well as at the very end, whereas \ez matches only at the
+end.
+.P
+The \eG assertion is true only when the current matching position is at the
+start point of the match, as specified by the \fIstartoffset\fP argument of
+\fBpcre2_match()\fP. It differs from \eA when the value of \fIstartoffset\fP is
+non-zero. By calling \fBpcre2_match()\fP multiple times with appropriate
+arguments, you can mimic Perl's /g option, and it is in this kind of
+implementation where \eG can be useful.
+.P
+Note, however, that PCRE2's interpretation of \eG, as the start of the current
+match, is subtly different from Perl's, which defines it as the end of the
+previous match. In Perl, these can be different when the previously matched
+string was empty. Because PCRE2 does just one match at a time, it cannot
+reproduce this behaviour.
+.P
+If all the alternatives of a pattern begin with \eG, the expression is anchored
+to the starting match position, and the "anchored" flag is set in the compiled
+regular expression.
+.
+.
+.SH "CIRCUMFLEX AND DOLLAR"
+.rs
+.sp
+The circumflex and dollar metacharacters are zero-width assertions. That is,
+they test for a particular condition being true without consuming any
+characters from the subject string. These two metacharacters are concerned with
+matching the starts and ends of lines. If the newline convention is set so that
+only the two-character sequence CRLF is recognized as a newline, isolated CR
+and LF characters are treated as ordinary data characters, and are not
+recognized as newlines.
+.P
+Outside a character class, in the default matching mode, the circumflex
+character is an assertion that is true only if the current matching point is at
+the start of the subject string. If the \fIstartoffset\fP argument of
+\fBpcre2_match()\fP is non-zero, or if PCRE2_NOTBOL is set, circumflex can
+never match if the PCRE2_MULTILINE option is unset. Inside a character class,
+circumflex has an entirely different meaning
+.\" HTML <a href="#characterclass">
+.\" </a>
+(see below).
+.\"
+.P
+Circumflex need not be the first character of the pattern if a number of
+alternatives are involved, but it should be the first thing in each alternative
+in which it appears if the pattern is ever to match that branch. If all
+possible alternatives start with a circumflex, that is, if the pattern is
+constrained to match only at the start of the subject, it is said to be an
+"anchored" pattern. (There are also other constructs that can cause a pattern
+to be anchored.)
+.P
+The dollar character is an assertion that is true only if the current matching
+point is at the end of the subject string, or immediately before a newline at
+the end of the string (by default), unless PCRE2_NOTEOL is set. Note, however,
+that it does not actually match the newline. Dollar need not be the last
+character of the pattern if a number of alternatives are involved, but it
+should be the last item in any branch in which it appears. Dollar has no
+special meaning in a character class.
+.P
+The meaning of dollar can be changed so that it matches only at the very end of
+the string, by setting the PCRE2_DOLLAR_ENDONLY option at compile time. This
+does not affect the \eZ assertion.
+.P
+The meanings of the circumflex and dollar metacharacters are changed if the
+PCRE2_MULTILINE option is set. When this is the case, a dollar character
+matches before any newlines in the string, as well as at the very end, and a
+circumflex matches immediately after internal newlines as well as at the start
+of the subject string. It does not match after a newline that ends the string,
+for compatibility with Perl. However, this can be changed by setting the
+PCRE2_ALT_CIRCUMFLEX option.
+.P
+For example, the pattern /^abc$/ matches the subject string "def\enabc" (where
+\en represents a newline) in multiline mode, but not otherwise. Consequently,
+patterns that are anchored in single line mode because all branches start with
+^ are not anchored in multiline mode, and a match for circumflex is possible
+when the \fIstartoffset\fP argument of \fBpcre2_match()\fP is non-zero. The
+PCRE2_DOLLAR_ENDONLY option is ignored if PCRE2_MULTILINE is set.
+.P
+When the newline convention (see
+.\" HTML <a href="#newlines">
+.\" </a>
+"Newline conventions"
+.\"
+below) recognizes the two-character sequence CRLF as a newline, this is
+preferred, even if the single characters CR and LF are also recognized as
+newlines. For example, if the newline convention is "any", a multiline mode
+circumflex matches before "xyz" in the string "abc\er\enxyz" rather than after
+CR, even though CR on its own is a valid newline. (It also matches at the very
+start of the string, of course.)
+.P
+Note that the sequences \eA, \eZ, and \ez can be used to match the start and
+end of the subject in both modes, and if all branches of a pattern start with
+\eA it is always anchored, whether or not PCRE2_MULTILINE is set.
+.
+.
+.\" HTML <a name="fullstopdot"></a>
+.SH "FULL STOP (PERIOD, DOT) AND \eN"
+.rs
+.sp
+Outside a character class, a dot in the pattern matches any one character in
+the subject string except (by default) a character that signifies the end of a
+line.
+.P
+When a line ending is defined as a single character, dot never matches that
+character; when the two-character sequence CRLF is used, dot does not match CR
+if it is immediately followed by LF, but otherwise it matches all characters
+(including isolated CRs and LFs). When any Unicode line endings are being
+recognized, dot does not match CR or LF or any of the other line ending
+characters.
+.P
+The behaviour of dot with regard to newlines can be changed. If the
+PCRE2_DOTALL option is set, a dot matches any one character, without exception.
+If the two-character sequence CRLF is present in the subject string, it takes
+two dots to match it.
+.P
+The handling of dot is entirely independent of the handling of circumflex and
+dollar, the only relationship being that they both involve newlines. Dot has no
+special meaning in a character class.
+.P
+The escape sequence \eN behaves like a dot, except that it is not affected by
+the PCRE2_DOTALL option. In other words, it matches any character except one
+that signifies the end of a line. Perl also uses \eN to match characters by
+name; PCRE2 does not support this.
+.
+.
+.SH "MATCHING A SINGLE CODE UNIT"
+.rs
+.sp
+Outside a character class, the escape sequence \eC matches any one code unit,
+whether or not a UTF mode is set. In the 8-bit library, one code unit is one
+byte; in the 16-bit library it is a 16-bit unit; in the 32-bit library it is a
+32-bit unit. Unlike a dot, \eC always matches line-ending characters. The
+feature is provided in Perl in order to match individual bytes in UTF-8 mode,
+but it is unclear how it can usefully be used.
+.P
+Because \eC breaks up characters into individual code units, matching one unit
+with \eC in UTF-8 or UTF-16 mode means that the rest of the string may start
+with a malformed UTF character. This has undefined results, because PCRE2
+assumes that it is matching character by character in a valid UTF string (by
+default it checks the subject string's validity at the start of processing
+unless the PCRE2_NO_UTF_CHECK option is used).
+.P
+An application can lock out the use of \eC by setting the
+PCRE2_NEVER_BACKSLASH_C option when compiling a pattern. It is also possible to
+build PCRE2 with the use of \eC permanently disabled.
+.P
+PCRE2 does not allow \eC to appear in lookbehind assertions
+.\" HTML <a href="#lookbehind">
+.\" </a>
+(described below)
+.\"
+in a UTF mode, because this would make it impossible to calculate the length of
+the lookbehind. Neither the alternative matching function
+\fBpcre2_dfa_match()\fP not the JIT optimizer support \eC in a UTF mode. The
+former gives a match-time error; the latter fails to optimize and so the match
+is always run using the interpreter.
+.P
+In general, the \eC escape sequence is best avoided. However, one way of using
+it that avoids the problem of malformed UTF characters is to use a lookahead to
+check the length of the next character, as in this pattern, which could be used
+with a UTF-8 string (ignore white space and line breaks):
+.sp
+ (?| (?=[\ex00-\ex7f])(\eC) |
+ (?=[\ex80-\ex{7ff}])(\eC)(\eC) |
+ (?=[\ex{800}-\ex{ffff}])(\eC)(\eC)(\eC) |
+ (?=[\ex{10000}-\ex{1fffff}])(\eC)(\eC)(\eC)(\eC))
+.sp
+In this example, a group that starts with (?| resets the capturing parentheses
+numbers in each alternative (see
+.\" HTML <a href="#dupsubpatternnumber">
+.\" </a>
+"Duplicate Subpattern Numbers"
+.\"
+below). The assertions at the start of each branch check the next UTF-8
+character for values whose encoding uses 1, 2, 3, or 4 bytes, respectively. The
+character's individual bytes are then captured by the appropriate number of
+\eC groups.
+.
+.
+.\" HTML <a name="characterclass"></a>
+.SH "SQUARE BRACKETS AND CHARACTER CLASSES"
+.rs
+.sp
+An opening square bracket introduces a character class, terminated by a closing
+square bracket. A closing square bracket on its own is not special by default.
+If a closing square bracket is required as a member of the class, it should be
+the first data character in the class (after an initial circumflex, if present)
+or escaped with a backslash. This means that, by default, an empty class cannot
+be defined. However, if the PCRE2_ALLOW_EMPTY_CLASS option is set, a closing
+square bracket at the start does end the (empty) class.
+.P
+A character class matches a single character in the subject. A matched
+character must be in the set of characters defined by the class, unless the
+first character in the class definition is a circumflex, in which case the
+subject character must not be in the set defined by the class. If a circumflex
+is actually required as a member of the class, ensure it is not the first
+character, or escape it with a backslash.
+.P
+For example, the character class [aeiou] matches any lower case vowel, while
+[^aeiou] matches any character that is not a lower case vowel. Note that a
+circumflex is just a convenient notation for specifying the characters that
+are in the class by enumerating those that are not. A class that starts with a
+circumflex is not an assertion; it still consumes a character from the subject
+string, and therefore it fails if the current pointer is at the end of the
+string.
+.P
+When caseless matching is set, any letters in a class represent both their
+upper case and lower case versions, so for example, a caseless [aeiou] matches
+"A" as well as "a", and a caseless [^aeiou] does not match "A", whereas a
+caseful version would.
+.P
+Characters that might indicate line breaks are never treated in any special way
+when matching character classes, whatever line-ending sequence is in use, and
+whatever setting of the PCRE2_DOTALL and PCRE2_MULTILINE options is used. A
+class such as [^a] always matches one of these characters.
+.P
+The minus (hyphen) character can be used to specify a range of characters in a
+character class. For example, [d-m] matches any letter between d and m,
+inclusive. If a minus character is required in a class, it must be escaped with
+a backslash or appear in a position where it cannot be interpreted as
+indicating a range, typically as the first or last character in the class, or
+immediately after a range. For example, [b-d-z] matches letters in the range b
+to d, a hyphen character, or z.
+.P
+It is not possible to have the literal character "]" as the end character of a
+range. A pattern such as [W-]46] is interpreted as a class of two characters
+("W" and "-") followed by a literal string "46]", so it would match "W46]" or
+"-46]". However, if the "]" is escaped with a backslash it is interpreted as
+the end of range, so [W-\e]46] is interpreted as a class containing a range
+followed by two other characters. The octal or hexadecimal representation of
+"]" can also be used to end a range.
+.P
+An error is generated if a POSIX character class (see below) or an escape
+sequence other than one that defines a single character appears at a point
+where a range ending character is expected. For example, [z-\exff] is valid,
+but [A-\ed] and [A-[:digit:]] are not.
+.P
+Ranges normally include all code points between the start and end characters,
+inclusive. They can also be used for code points specified numerically, for
+example [\e000-\e037]. Ranges can include any characters that are valid for the
+current mode.
+.P
+There is a special case in EBCDIC environments for ranges whose end points are
+both specified as literal letters in the same case. For compatibility with
+Perl, EBCDIC code points within the range that are not letters are omitted. For
+example, [h-k] matches only four characters, even though the codes for h and k
+are 0x88 and 0x92, a range of 11 code points. However, if the range is
+specified numerically, for example, [\ex88-\ex92] or [h-\ex92], all code points
+are included.
+.P
+If a range that includes letters is used when caseless matching is set, it
+matches the letters in either case. For example, [W-c] is equivalent to
+[][\e\e^_`wxyzabc], matched caselessly, and in a non-UTF mode, if character
+tables for a French locale are in use, [\exc8-\excb] matches accented E
+characters in both cases.
+.P
+The character escape sequences \ed, \eD, \eh, \eH, \ep, \eP, \es, \eS, \ev,
+\eV, \ew, and \eW may appear in a character class, and add the characters that
+they match to the class. For example, [\edABCDEF] matches any hexadecimal
+digit. In UTF modes, the PCRE2_UCP option affects the meanings of \ed, \es, \ew
+and their upper case partners, just as it does when they appear outside a
+character class, as described in the section entitled
+.\" HTML <a href="#genericchartypes">
+.\" </a>
+"Generic character types"
+.\"
+above. The escape sequence \eb has a different meaning inside a character
+class; it matches the backspace character. The sequences \eB, \eN, \eR, and \eX
+are not special inside a character class. Like any other unrecognized escape
+sequences, they cause an error.
+.P
+A circumflex can conveniently be used with the upper case character types to
+specify a more restricted set of characters than the matching lower case type.
+For example, the class [^\eW_] matches any letter or digit, but not underscore,
+whereas [\ew] includes underscore. A positive character class should be read as
+"something OR something OR ..." and a negative class as "NOT something AND NOT
+something AND NOT ...".
+.P
+The only metacharacters that are recognized in character classes are backslash,
+hyphen (only where it can be interpreted as specifying a range), circumflex
+(only at the start), opening square bracket (only when it can be interpreted as
+introducing a POSIX class name, or for a special compatibility feature - see
+the next two sections), and the terminating closing square bracket. However,
+escaping other non-alphanumeric characters does no harm.
+.
+.
+.SH "POSIX CHARACTER CLASSES"
+.rs
+.sp
+Perl supports the POSIX notation for character classes. This uses names
+enclosed by [: and :] within the enclosing square brackets. PCRE2 also supports
+this notation. For example,
+.sp
+ [01[:alpha:]%]
+.sp
+matches "0", "1", any alphabetic character, or "%". The supported class names
+are:
+.sp
+ alnum letters and digits
+ alpha letters
+ ascii character codes 0 - 127
+ blank space or tab only
+ cntrl control characters
+ digit decimal digits (same as \ed)
+ graph printing characters, excluding space
+ lower lower case letters
+ print printing characters, including space
+ punct printing characters, excluding letters and digits and space
+ space white space (the same as \es from PCRE2 8.34)
+ upper upper case letters
+ word "word" characters (same as \ew)
+ xdigit hexadecimal digits
+.sp
+The default "space" characters are HT (9), LF (10), VT (11), FF (12), CR (13),
+and space (32). If locale-specific matching is taking place, the list of space
+characters may be different; there may be fewer or more of them. "Space" and
+\es match the same set of characters.
+.P
+The name "word" is a Perl extension, and "blank" is a GNU extension from Perl
+5.8. Another Perl extension is negation, which is indicated by a ^ character
+after the colon. For example,
+.sp
+ [12[:^digit:]]
+.sp
+matches "1", "2", or any non-digit. PCRE2 (and Perl) also recognize the POSIX
+syntax [.ch.] and [=ch=] where "ch" is a "collating element", but these are not
+supported, and an error is given if they are encountered.
+.P
+By default, characters with values greater than 127 do not match any of the
+POSIX character classes, although this may be different for characters in the
+range 128-255 when locale-specific matching is happening. However, if the
+PCRE2_UCP option is passed to \fBpcre2_compile()\fP, some of the classes are
+changed so that Unicode character properties are used. This is achieved by
+replacing certain POSIX classes with other sequences, as follows:
+.sp
+ [:alnum:] becomes \ep{Xan}
+ [:alpha:] becomes \ep{L}
+ [:blank:] becomes \eh
+ [:cntrl:] becomes \ep{Cc}
+ [:digit:] becomes \ep{Nd}
+ [:lower:] becomes \ep{Ll}
+ [:space:] becomes \ep{Xps}
+ [:upper:] becomes \ep{Lu}
+ [:word:] becomes \ep{Xwd}
+.sp
+Negated versions, such as [:^alpha:] use \eP instead of \ep. Three other POSIX
+classes are handled specially in UCP mode:
+.TP 10
+[:graph:]
+This matches characters that have glyphs that mark the page when printed. In
+Unicode property terms, it matches all characters with the L, M, N, P, S, or Cf
+properties, except for:
+.sp
+ U+061C Arabic Letter Mark
+ U+180E Mongolian Vowel Separator
+ U+2066 - U+2069 Various "isolate"s
+.sp
+.TP 10
+[:print:]
+This matches the same characters as [:graph:] plus space characters that are
+not controls, that is, characters with the Zs property.
+.TP 10
+[:punct:]
+This matches all characters that have the Unicode P (punctuation) property,
+plus those characters with code points less than 256 that have the S (Symbol)
+property.
+.P
+The other POSIX classes are unchanged, and match only characters with code
+points less than 256.
+.
+.
+.SH "COMPATIBILITY FEATURE FOR WORD BOUNDARIES"
+.rs
+.sp
+In the POSIX.2 compliant library that was included in 4.4BSD Unix, the ugly
+syntax [[:<:]] and [[:>:]] is used for matching "start of word" and "end of
+word". PCRE2 treats these items as follows:
+.sp
+ [[:<:]] is converted to \eb(?=\ew)
+ [[:>:]] is converted to \eb(?<=\ew)
+.sp
+Only these exact character sequences are recognized. A sequence such as
+[a[:<:]b] provokes error for an unrecognized POSIX class name. This support is
+not compatible with Perl. It is provided to help migrations from other
+environments, and is best not used in any new patterns. Note that \eb matches
+at the start and the end of a word (see
+.\" HTML <a href="#smallassertions">
+.\" </a>
+"Simple assertions"
+.\"
+above), and in a Perl-style pattern the preceding or following character
+normally shows which is wanted, without the need for the assertions that are
+used above in order to give exactly the POSIX behaviour.
+.
+.
+.SH "VERTICAL BAR"
+.rs
+.sp
+Vertical bar characters are used to separate alternative patterns. For example,
+the pattern
+.sp
+ gilbert|sullivan
+.sp
+matches either "gilbert" or "sullivan". Any number of alternatives may appear,
+and an empty alternative is permitted (matching the empty string). The matching
+process tries each alternative in turn, from left to right, and the first one
+that succeeds is used. If the alternatives are within a subpattern
+.\" HTML <a href="#subpattern">
+.\" </a>
+(defined below),
+.\"
+"succeeds" means matching the rest of the main pattern as well as the
+alternative in the subpattern.
+.
+.
+.SH "INTERNAL OPTION SETTING"
+.rs
+.sp
+The settings of the PCRE2_CASELESS, PCRE2_MULTILINE, PCRE2_DOTALL, and
+PCRE2_EXTENDED options (which are Perl-compatible) can be changed from within
+the pattern by a sequence of Perl option letters enclosed between "(?" and ")".
+The option letters are
+.sp
+ i for PCRE2_CASELESS
+ m for PCRE2_MULTILINE
+ s for PCRE2_DOTALL
+ x for PCRE2_EXTENDED
+.sp
+For example, (?im) sets caseless, multiline matching. It is also possible to
+unset these options by preceding the letter with a hyphen, and a combined
+setting and unsetting such as (?im-sx), which sets PCRE2_CASELESS and
+PCRE2_MULTILINE while unsetting PCRE2_DOTALL and PCRE2_EXTENDED, is also
+permitted. If a letter appears both before and after the hyphen, the option is
+unset. An empty options setting "(?)" is allowed. Needless to say, it has no
+effect.
+.P
+The PCRE2-specific options PCRE2_DUPNAMES and PCRE2_UNGREEDY can be changed in
+the same way as the Perl-compatible options by using the characters J and U
+respectively.
+.P
+When one of these option changes occurs at top level (that is, not inside
+subpattern parentheses), the change applies to the remainder of the pattern
+that follows. If the change is placed right at the start of a pattern, PCRE2
+extracts it into the global options (and it will therefore show up in data
+extracted by the \fBpcre2_pattern_info()\fP function).
+.P
+An option change within a subpattern (see below for a description of
+subpatterns) affects only that part of the subpattern that follows it, so
+.sp
+ (a(?i)b)c
+.sp
+matches abc and aBc and no other strings (assuming PCRE2_CASELESS is not used).
+By this means, options can be made to have different settings in different
+parts of the pattern. Any changes made in one alternative do carry on
+into subsequent branches within the same subpattern. For example,
+.sp
+ (a(?i)b|c)
+.sp
+matches "ab", "aB", "c", and "C", even though when matching "C" the first
+branch is abandoned before the option setting. This is because the effects of
+option settings happen at compile time. There would be some very weird
+behaviour otherwise.
+.P
+As a convenient shorthand, if any option settings are required at the start of
+a non-capturing subpattern (see the next section), the option letters may
+appear between the "?" and the ":". Thus the two patterns
+.sp
+ (?i:saturday|sunday)
+ (?:(?i)saturday|sunday)
+.sp
+match exactly the same set of strings.
+.P
+\fBNote:\fP There are other PCRE2-specific options that can be set by the
+application when the compiling function is called. The pattern can contain
+special leading sequences such as (*CRLF) to override what the application has
+set or what has been defaulted. Details are given in the section entitled
+.\" HTML <a href="#newlineseq">
+.\" </a>
+"Newline sequences"
+.\"
+above. There are also the (*UTF) and (*UCP) leading sequences that can be used
+to set UTF and Unicode property modes; they are equivalent to setting the
+PCRE2_UTF and PCRE2_UCP options, respectively. However, the application can set
+the PCRE2_NEVER_UTF and PCRE2_NEVER_UCP options, which lock out the use of the
+(*UTF) and (*UCP) sequences.
+.
+.
+.\" HTML <a name="subpattern"></a>
+.SH SUBPATTERNS
+.rs
+.sp
+Subpatterns are delimited by parentheses (round brackets), which can be nested.
+Turning part of a pattern into a subpattern does two things:
+.sp
+1. It localizes a set of alternatives. For example, the pattern
+.sp
+ cat(aract|erpillar|)
+.sp
+matches "cataract", "caterpillar", or "cat". Without the parentheses, it would
+match "cataract", "erpillar" or an empty string.
+.sp
+2. It sets up the subpattern as a capturing subpattern. This means that, when
+the whole pattern matches, the portion of the subject string that matched the
+subpattern is passed back to the caller, separately from the portion that
+matched the whole pattern. (This applies only to the traditional matching
+function; the DFA matching function does not support capturing.)
+.P
+Opening parentheses are counted from left to right (starting from 1) to obtain
+numbers for the capturing subpatterns. For example, if the string "the red
+king" is matched against the pattern
+.sp
+ the ((red|white) (king|queen))
+.sp
+the captured substrings are "red king", "red", and "king", and are numbered 1,
+2, and 3, respectively.
+.P
+The fact that plain parentheses fulfil two functions is not always helpful.
+There are often times when a grouping subpattern is required without a
+capturing requirement. If an opening parenthesis is followed by a question mark
+and a colon, the subpattern does not do any capturing, and is not counted when
+computing the number of any subsequent capturing subpatterns. For example, if
+the string "the white queen" is matched against the pattern
+.sp
+ the ((?:red|white) (king|queen))
+.sp
+the captured substrings are "white queen" and "queen", and are numbered 1 and
+2. The maximum number of capturing subpatterns is 65535.
+.P
+As a convenient shorthand, if any option settings are required at the start of
+a non-capturing subpattern, the option letters may appear between the "?" and
+the ":". Thus the two patterns
+.sp
+ (?i:saturday|sunday)
+ (?:(?i)saturday|sunday)
+.sp
+match exactly the same set of strings. Because alternative branches are tried
+from left to right, and options are not reset until the end of the subpattern
+is reached, an option setting in one branch does affect subsequent branches, so
+the above patterns match "SUNDAY" as well as "Saturday".
+.
+.
+.\" HTML <a name="dupsubpatternnumber"></a>
+.SH "DUPLICATE SUBPATTERN NUMBERS"
+.rs
+.sp
+Perl 5.10 introduced a feature whereby each alternative in a subpattern uses
+the same numbers for its capturing parentheses. Such a subpattern starts with
+(?| and is itself a non-capturing subpattern. For example, consider this
+pattern:
+.sp
+ (?|(Sat)ur|(Sun))day
+.sp
+Because the two alternatives are inside a (?| group, both sets of capturing
+parentheses are numbered one. Thus, when the pattern matches, you can look
+at captured substring number one, whichever alternative matched. This construct
+is useful when you want to capture part, but not all, of one of a number of
+alternatives. Inside a (?| group, parentheses are numbered as usual, but the
+number is reset at the start of each branch. The numbers of any capturing
+parentheses that follow the subpattern start after the highest number used in
+any branch. The following example is taken from the Perl documentation. The
+numbers underneath show in which buffer the captured content will be stored.
+.sp
+ # before ---------------branch-reset----------- after
+ / ( a ) (?| x ( y ) z | (p (q) r) | (t) u (v) ) ( z ) /x
+ # 1 2 2 3 2 3 4
+.sp
+A back reference to a numbered subpattern uses the most recent value that is
+set for that number by any subpattern. The following pattern matches "abcabc"
+or "defdef":
+.sp
+ /(?|(abc)|(def))\e1/
+.sp
+In contrast, a subroutine call to a numbered subpattern always refers to the
+first one in the pattern with the given number. The following pattern matches
+"abcabc" or "defabc":
+.sp
+ /(?|(abc)|(def))(?1)/
+.sp
+A relative reference such as (?-1) is no different: it is just a convenient way
+of computing an absolute group number.
+.P
+If a
+.\" HTML <a href="#conditions">
+.\" </a>
+condition test
+.\"
+for a subpattern's having matched refers to a non-unique number, the test is
+true if any of the subpatterns of that number have matched.
+.P
+An alternative approach to using this "branch reset" feature is to use
+duplicate named subpatterns, as described in the next section.
+.
+.
+.SH "NAMED SUBPATTERNS"
+.rs
+.sp
+Identifying capturing parentheses by number is simple, but it can be very hard
+to keep track of the numbers in complicated regular expressions. Furthermore,
+if an expression is modified, the numbers may change. To help with this
+difficulty, PCRE2 supports the naming of subpatterns. This feature was not
+added to Perl until release 5.10. Python had the feature earlier, and PCRE1
+introduced it at release 4.0, using the Python syntax. PCRE2 supports both the
+Perl and the Python syntax. Perl allows identically numbered subpatterns to
+have different names, but PCRE2 does not.
+.P
+In PCRE2, a subpattern can be named in one of three ways: (?<name>...) or
+(?'name'...) as in Perl, or (?P<name>...) as in Python. References to capturing
+parentheses from other parts of the pattern, such as
+.\" HTML <a href="#backreferences">
+.\" </a>
+back references,
+.\"
+.\" HTML <a href="#recursion">
+.\" </a>
+recursion,
+.\"
+and
+.\" HTML <a href="#conditions">
+.\" </a>
+conditions,
+.\"
+can be made by name as well as by number.
+.P
+Names consist of up to 32 alphanumeric characters and underscores, but must
+start with a non-digit. Named capturing parentheses are still allocated numbers
+as well as names, exactly as if the names were not present. The PCRE2 API
+provides function calls for extracting the name-to-number translation table
+from a compiled pattern. There are also convenience functions for extracting a
+captured substring by name.
+.P
+By default, a name must be unique within a pattern, but it is possible to relax
+this constraint by setting the PCRE2_DUPNAMES option at compile time.
+(Duplicate names are also always permitted for subpatterns with the same
+number, set up as described in the previous section.) Duplicate names can be
+useful for patterns where only one instance of the named parentheses can match.
+Suppose you want to match the name of a weekday, either as a 3-letter
+abbreviation or as the full name, and in both cases you want to extract the
+abbreviation. This pattern (ignoring the line breaks) does the job:
+.sp
+ (?<DN>Mon|Fri|Sun)(?:day)?|
+ (?<DN>Tue)(?:sday)?|
+ (?<DN>Wed)(?:nesday)?|
+ (?<DN>Thu)(?:rsday)?|
+ (?<DN>Sat)(?:urday)?
+.sp
+There are five capturing substrings, but only one is ever set after a match.
+(An alternative way of solving this problem is to use a "branch reset"
+subpattern, as described in the previous section.)
+.P
+The convenience functions for extracting the data by name returns the substring
+for the first (and in this example, the only) subpattern of that name that
+matched. This saves searching to find which numbered subpattern it was.
+.P
+If you make a back reference to a non-unique named subpattern from elsewhere in
+the pattern, the subpatterns to which the name refers are checked in the order
+in which they appear in the overall pattern. The first one that is set is used
+for the reference. For example, this pattern matches both "foofoo" and
+"barbar" but not "foobar" or "barfoo":
+.sp
+ (?:(?<n>foo)|(?<n>bar))\ek<n>
+.sp
+.P
+If you make a subroutine call to a non-unique named subpattern, the one that
+corresponds to the first occurrence of the name is used. In the absence of
+duplicate numbers (see the previous section) this is the one with the lowest
+number.
+.P
+If you use a named reference in a condition
+test (see the
+.\"
+.\" HTML <a href="#conditions">
+.\" </a>
+section about conditions
+.\"
+below), either to check whether a subpattern has matched, or to check for
+recursion, all subpatterns with the same name are tested. If the condition is
+true for any one of them, the overall condition is true. This is the same
+behaviour as testing by number. For further details of the interfaces for
+handling named subpatterns, see the
+.\" HREF
+\fBpcre2api\fP
+.\"
+documentation.
+.P
+\fBWarning:\fP You cannot use different names to distinguish between two
+subpatterns with the same number because PCRE2 uses only the numbers when
+matching. For this reason, an error is given at compile time if different names
+are given to subpatterns with the same number. However, you can always give the
+same name to subpatterns with the same number, even when PCRE2_DUPNAMES is not
+set.
+.
+.
+.SH REPETITION
+.rs
+.sp
+Repetition is specified by quantifiers, which can follow any of the following
+items:
+.sp
+ a literal data character
+ the dot metacharacter
+ the \eC escape sequence
+ the \eX escape sequence
+ the \eR escape sequence
+ an escape such as \ed or \epL that matches a single character
+ a character class
+ a back reference
+ a parenthesized subpattern (including most assertions)
+ a subroutine call to a subpattern (recursive or otherwise)
+.sp
+The general repetition quantifier specifies a minimum and maximum number of
+permitted matches, by giving the two numbers in curly brackets (braces),
+separated by a comma. The numbers must be less than 65536, and the first must
+be less than or equal to the second. For example:
+.sp
+ z{2,4}
+.sp
+matches "zz", "zzz", or "zzzz". A closing brace on its own is not a special
+character. If the second number is omitted, but the comma is present, there is
+no upper limit; if the second number and the comma are both omitted, the
+quantifier specifies an exact number of required matches. Thus
+.sp
+ [aeiou]{3,}
+.sp
+matches at least 3 successive vowels, but may match many more, whereas
+.sp
+ \ed{8}
+.sp
+matches exactly 8 digits. An opening curly bracket that appears in a position
+where a quantifier is not allowed, or one that does not match the syntax of a
+quantifier, is taken as a literal character. For example, {,6} is not a
+quantifier, but a literal string of four characters.
+.P
+In UTF modes, quantifiers apply to characters rather than to individual code
+units. Thus, for example, \ex{100}{2} matches two characters, each of
+which is represented by a two-byte sequence in a UTF-8 string. Similarly,
+\eX{3} matches three Unicode extended grapheme clusters, each of which may be
+several code units long (and they may be of different lengths).
+.P
+The quantifier {0} is permitted, causing the expression to behave as if the
+previous item and the quantifier were not present. This may be useful for
+subpatterns that are referenced as
+.\" HTML <a href="#subpatternsassubroutines">
+.\" </a>
+subroutines
+.\"
+from elsewhere in the pattern (but see also the section entitled
+.\" HTML <a href="#subdefine">
+.\" </a>
+"Defining subpatterns for use by reference only"
+.\"
+below). Items other than subpatterns that have a {0} quantifier are omitted
+from the compiled pattern.
+.P
+For convenience, the three most common quantifiers have single-character
+abbreviations:
+.sp
+ * is equivalent to {0,}
+ + is equivalent to {1,}
+ ? is equivalent to {0,1}
+.sp
+It is possible to construct infinite loops by following a subpattern that can
+match no characters with a quantifier that has no upper limit, for example:
+.sp
+ (a?)*
+.sp
+Earlier versions of Perl and PCRE1 used to give an error at compile time for
+such patterns. However, because there are cases where this can be useful, such
+patterns are now accepted, but if any repetition of the subpattern does in fact
+match no characters, the loop is forcibly broken.
+.P
+By default, the quantifiers are "greedy", that is, they match as much as
+possible (up to the maximum number of permitted times), without causing the
+rest of the pattern to fail. The classic example of where this gives problems
+is in trying to match comments in C programs. These appear between /* and */
+and within the comment, individual * and / characters may appear. An attempt to
+match C comments by applying the pattern
+.sp
+ /\e*.*\e*/
+.sp
+to the string
+.sp
+ /* first comment */ not comment /* second comment */
+.sp
+fails, because it matches the entire string owing to the greediness of the .*
+item.
+.P
+If a quantifier is followed by a question mark, it ceases to be greedy, and
+instead matches the minimum number of times possible, so the pattern
+.sp
+ /\e*.*?\e*/
+.sp
+does the right thing with the C comments. The meaning of the various
+quantifiers is not otherwise changed, just the preferred number of matches.
+Do not confuse this use of question mark with its use as a quantifier in its
+own right. Because it has two uses, it can sometimes appear doubled, as in
+.sp
+ \ed??\ed
+.sp
+which matches one digit by preference, but can match two if that is the only
+way the rest of the pattern matches.
+.P
+If the PCRE2_UNGREEDY option is set (an option that is not available in Perl),
+the quantifiers are not greedy by default, but individual ones can be made
+greedy by following them with a question mark. In other words, it inverts the
+default behaviour.
+.P
+When a parenthesized subpattern is quantified with a minimum repeat count that
+is greater than 1 or with a limited maximum, more memory is required for the
+compiled pattern, in proportion to the size of the minimum or maximum.
+.P
+If a pattern starts with .* or .{0,} and the PCRE2_DOTALL option (equivalent
+to Perl's /s) is set, thus allowing the dot to match newlines, the pattern is
+implicitly anchored, because whatever follows will be tried against every
+character position in the subject string, so there is no point in retrying the
+overall match at any position after the first. PCRE2 normally treats such a
+pattern as though it were preceded by \eA.
+.P
+In cases where it is known that the subject string contains no newlines, it is
+worth setting PCRE2_DOTALL in order to obtain this optimization, or
+alternatively, using ^ to indicate anchoring explicitly.
+.P
+However, there are some cases where the optimization cannot be used. When .*
+is inside capturing parentheses that are the subject of a back reference
+elsewhere in the pattern, a match at the start may fail where a later one
+succeeds. Consider, for example:
+.sp
+ (.*)abc\e1
+.sp
+If the subject is "xyz123abc123" the match point is the fourth character. For
+this reason, such a pattern is not implicitly anchored.
+.P
+Another case where implicit anchoring is not applied is when the leading .* is
+inside an atomic group. Once again, a match at the start may fail where a later
+one succeeds. Consider this pattern:
+.sp
+ (?>.*?a)b
+.sp
+It matches "ab" in the subject "aab". The use of the backtracking control verbs
+(*PRUNE) and (*SKIP) also disable this optimization, and there is an option,
+PCRE2_NO_DOTSTAR_ANCHOR, to do so explicitly.
+.P
+When a capturing subpattern is repeated, the value captured is the substring
+that matched the final iteration. For example, after
+.sp
+ (tweedle[dume]{3}\es*)+
+.sp
+has matched "tweedledum tweedledee" the value of the captured substring is
+"tweedledee". However, if there are nested capturing subpatterns, the
+corresponding captured values may have been set in previous iterations. For
+example, after
+.sp
+ (a|(b))+
+.sp
+matches "aba" the value of the second captured substring is "b".
+.
+.
+.\" HTML <a name="atomicgroup"></a>
+.SH "ATOMIC GROUPING AND POSSESSIVE QUANTIFIERS"
+.rs
+.sp
+With both maximizing ("greedy") and minimizing ("ungreedy" or "lazy")
+repetition, failure of what follows normally causes the repeated item to be
+re-evaluated to see if a different number of repeats allows the rest of the
+pattern to match. Sometimes it is useful to prevent this, either to change the
+nature of the match, or to cause it fail earlier than it otherwise might, when
+the author of the pattern knows there is no point in carrying on.
+.P
+Consider, for example, the pattern \ed+foo when applied to the subject line
+.sp
+ 123456bar
+.sp
+After matching all 6 digits and then failing to match "foo", the normal
+action of the matcher is to try again with only 5 digits matching the \ed+
+item, and then with 4, and so on, before ultimately failing. "Atomic grouping"
+(a term taken from Jeffrey Friedl's book) provides the means for specifying
+that once a subpattern has matched, it is not to be re-evaluated in this way.
+.P
+If we use atomic grouping for the previous example, the matcher gives up
+immediately on failing to match "foo" the first time. The notation is a kind of
+special parenthesis, starting with (?> as in this example:
+.sp
+ (?>\ed+)foo
+.sp
+This kind of parenthesis "locks up" the part of the pattern it contains once
+it has matched, and a failure further into the pattern is prevented from
+backtracking into it. Backtracking past it to previous items, however, works as
+normal.
+.P
+An alternative description is that a subpattern of this type matches exactly
+the string of characters that an identical standalone pattern would match, if
+anchored at the current point in the subject string.
+.P
+Atomic grouping subpatterns are not capturing subpatterns. Simple cases such as
+the above example can be thought of as a maximizing repeat that must swallow
+everything it can. So, while both \ed+ and \ed+? are prepared to adjust the
+number of digits they match in order to make the rest of the pattern match,
+(?>\ed+) can only match an entire sequence of digits.
+.P
+Atomic groups in general can of course contain arbitrarily complicated
+subpatterns, and can be nested. However, when the subpattern for an atomic
+group is just a single repeated item, as in the example above, a simpler
+notation, called a "possessive quantifier" can be used. This consists of an
+additional + character following a quantifier. Using this notation, the
+previous example can be rewritten as
+.sp
+ \ed++foo
+.sp
+Note that a possessive quantifier can be used with an entire group, for
+example:
+.sp
+ (abc|xyz){2,3}+
+.sp
+Possessive quantifiers are always greedy; the setting of the PCRE2_UNGREEDY
+option is ignored. They are a convenient notation for the simpler forms of
+atomic group. However, there is no difference in the meaning of a possessive
+quantifier and the equivalent atomic group, though there may be a performance
+difference; possessive quantifiers should be slightly faster.
+.P
+The possessive quantifier syntax is an extension to the Perl 5.8 syntax.
+Jeffrey Friedl originated the idea (and the name) in the first edition of his
+book. Mike McCloskey liked it, so implemented it when he built Sun's Java
+package, and PCRE1 copied it from there. It ultimately found its way into Perl
+at release 5.10.
+.P
+PCRE2 has an optimization that automatically "possessifies" certain simple
+pattern constructs. For example, the sequence A+B is treated as A++B because
+there is no point in backtracking into a sequence of A's when B must follow.
+This feature can be disabled by the PCRE2_NO_AUTOPOSSESS option, or starting
+the pattern with (*NO_AUTO_POSSESS).
+.P
+When a pattern contains an unlimited repeat inside a subpattern that can itself
+be repeated an unlimited number of times, the use of an atomic group is the
+only way to avoid some failing matches taking a very long time indeed. The
+pattern
+.sp
+ (\eD+|<\ed+>)*[!?]
+.sp
+matches an unlimited number of substrings that either consist of non-digits, or
+digits enclosed in <>, followed by either ! or ?. When it matches, it runs
+quickly. However, if it is applied to
+.sp
+ aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
+.sp
+it takes a long time before reporting failure. This is because the string can
+be divided between the internal \eD+ repeat and the external * repeat in a
+large number of ways, and all have to be tried. (The example uses [!?] rather
+than a single character at the end, because both PCRE2 and Perl have an
+optimization that allows for fast failure when a single character is used. They
+remember the last single character that is required for a match, and fail early
+if it is not present in the string.) If the pattern is changed so that it uses
+an atomic group, like this:
+.sp
+ ((?>\eD+)|<\ed+>)*[!?]
+.sp
+sequences of non-digits cannot be broken, and failure happens quickly.

+.
+.\" HTML <a name="backreferences"></a>
+.SH "BACK REFERENCES"
+.rs
+.sp
+Outside a character class, a backslash followed by a digit greater than 0 (and
+possibly further digits) is a back reference to a capturing subpattern earlier
+(that is, to its left) in the pattern, provided there have been that many
+previous capturing left parentheses.
+.P
+However, if the decimal number following the backslash is less than 8, it is
+always taken as a back reference, and causes an error only if there are not
+that many capturing left parentheses in the entire pattern. In other words, the
+parentheses that are referenced need not be to the left of the reference for
+numbers less than 8. A "forward back reference" of this type can make sense
+when a repetition is involved and the subpattern to the right has participated
+in an earlier iteration.
+.P
+It is not possible to have a numerical "forward back reference" to a subpattern
+whose number is 8 or more using this syntax because a sequence such as \e50 is
+interpreted as a character defined in octal. See the subsection entitled
+"Non-printing characters"
+.\" HTML <a href="#digitsafterbackslash">
+.\" </a>
+above
+.\"
+for further details of the handling of digits following a backslash. There is
+no such problem when named parentheses are used. A back reference to any
+subpattern is possible using named parentheses (see below).
+.P
+Another way of avoiding the ambiguity inherent in the use of digits following a
+backslash is to use the \eg escape sequence. This escape must be followed by an
+unsigned number or a negative number, optionally enclosed in braces. These
+examples are all identical:
+.sp
+ (ring), \e1
+ (ring), \eg1
+ (ring), \eg{1}
+.sp
+An unsigned number specifies an absolute reference without the ambiguity that
+is present in the older syntax. It is also useful when literal digits follow
+the reference. A negative number is a relative reference. Consider this
+example:
+.sp
+ (abc(def)ghi)\eg{-1}
+.sp
+The sequence \eg{-1} is a reference to the most recently started capturing
+subpattern before \eg, that is, is it equivalent to \e2 in this example.
+Similarly, \eg{-2} would be equivalent to \e1. The use of relative references
+can be helpful in long patterns, and also in patterns that are created by
+joining together fragments that contain references within themselves.
+.P
+A back reference matches whatever actually matched the capturing subpattern in
+the current subject string, rather than anything matching the subpattern
+itself (see
+.\" HTML <a href="#subpatternsassubroutines">
+.\" </a>
+"Subpatterns as subroutines"
+.\"
+below for a way of doing that). So the pattern
+.sp
+ (sens|respons)e and \e1ibility
+.sp
+matches "sense and sensibility" and "response and responsibility", but not
+"sense and responsibility". If caseful matching is in force at the time of the
+back reference, the case of letters is relevant. For example,
+.sp
+ ((?i)rah)\es+\e1
+.sp
+matches "rah rah" and "RAH RAH", but not "RAH rah", even though the original
+capturing subpattern is matched caselessly.
+.P
+There are several different ways of writing back references to named
+subpatterns. The .NET syntax \ek{name} and the Perl syntax \ek<name> or
+\ek'name' are supported, as is the Python syntax (?P=name). Perl 5.10's unified
+back reference syntax, in which \eg can be used for both numeric and named
+references, is also supported. We could rewrite the above example in any of
+the following ways:
+.sp
+ (?<p1>(?i)rah)\es+\ek<p1>
+ (?'p1'(?i)rah)\es+\ek{p1}
+ (?P<p1>(?i)rah)\es+(?P=p1)
+ (?<p1>(?i)rah)\es+\eg{p1}
+.sp
+A subpattern that is referenced by name may appear in the pattern before or
+after the reference.
+.P
+There may be more than one back reference to the same subpattern. If a
+subpattern has not actually been used in a particular match, any back
+references to it always fail by default. For example, the pattern
+.sp
+ (a|(bc))\e2
+.sp
+always fails if it starts to match "a" rather than "bc". However, if the
+PCRE2_MATCH_UNSET_BACKREF option is set at compile time, a back reference to an
+unset value matches an empty string.
+.P
+Because there may be many capturing parentheses in a pattern, all digits
+following a backslash are taken as part of a potential back reference number.
+If the pattern continues with a digit character, some delimiter must be used to
+terminate the back reference. If the PCRE2_EXTENDED option is set, this can be
+white space. Otherwise, the \eg{ syntax or an empty comment (see
+.\" HTML <a href="#comments">
+.\" </a>
+"Comments"
+.\"
+below) can be used.
+.
+.
+.SS "Recursive back references"
+.rs
+.sp
+A back reference that occurs inside the parentheses to which it refers fails
+when the subpattern is first used, so, for example, (a\e1) never matches.
+However, such references can be useful inside repeated subpatterns. For
+example, the pattern
+.sp
+ (a|b\e1)+
+.sp
+matches any number of "a"s and also "aba", "ababbaa" etc. At each iteration of
+the subpattern, the back reference matches the character string corresponding
+to the previous iteration. In order for this to work, the pattern must be such
+that the first iteration does not need to match the back reference. This can be
+done using alternation, as in the example above, or by a quantifier with a
+minimum of zero.
+.P
+Back references of this type cause the group that they reference to be treated
+as an

+.\" HTML <a name="bigassertions"></a>
+.SH ASSERTIONS
+.rs
+.sp
+An assertion is a test on the characters following or preceding the current
+matching point that does not consume any characters. The simple assertions
+coded as \eb, \eB, \eA, \eG, \eZ, \ez, ^ and $ are described
+.\" HTML <a href="#smallassertions">
+.\" </a>
+above.
+.\"
+.P
+More complicated assertions are coded as subpatterns. There are two kinds:
+those that look ahead of the current position in the subject string, and those
+that look behind it. An assertion subpattern is matched in the normal way,
+except that it does not cause the current matching position to be changed.
+.P
+Assertion subpatterns are not capturing subpatterns. If such an assertion
+contains capturing subpatterns within it, these are counted for the purposes of
+numbering the capturing subpatterns in the whole pattern. However, substring
+capturing is carried out only for positive assertions. (Perl sometimes, but not
+always, does do capturing in negative assertions.)
+.P
+For compatibility with Perl, most assertion subpatterns may be repeated; though
+it makes no sense to assert the same thing several times, the side effect of
+capturing parentheses may occasionally be useful. However, an assertion that
+forms the condition for a conditional subpattern may not be quantified. In
+practice, for other assertions, there only three cases:
+.sp
+(1) If the quantifier is {0}, the assertion is never obeyed during matching.
+However, it may contain internal capturing parenthesized groups that are called
+from elsewhere via the
+.\" HTML <a href="#subpatternsassubroutines">
+.\" </a>
+subroutine mechanism.
+.\"
+.sp
+(2) If quantifier is {0,n} where n is greater than zero, it is treated as if it
+were {0,1}. At run time, the rest of the pattern match is tried with and
+without the assertion, the order depending on the greediness of the quantifier.
+.sp
+(3) If the minimum repetition is greater than zero, the quantifier is ignored.
+The assertion is obeyed just once when encountered during matching.
+.
+.
+.SS "Lookahead assertions"
+.rs
+.sp
+Lookahead assertions start with (?= for positive assertions and (?! for
+negative assertions. For example,
+.sp
+ \ew+(?=;)
+.sp
+matches a word followed by a semicolon, but does not include the semicolon in
+the match, and
+.sp
+ foo(?!bar)
+.sp
+matches any occurrence of "foo" that is not followed by "bar". Note that the
+apparently similar pattern
+.sp
+ (?!foo)bar
+.sp
+does not find an occurrence of "bar" that is preceded by something other than
+"foo"; it finds any occurrence of "bar" whatsoever, because the assertion
+(?!foo) is always true when the next three characters are "bar". A
+lookbehind assertion is needed to achieve the other effect.
+.P
+If you want to force a matching failure at some point in a pattern, the most
+convenient way to do it is with (?!) because an empty string always matches, so
+an assertion that requires there not to be an empty string must always fail.
+The backtracking control verb (*FAIL) or (*F) is a synonym for (?!).
+.
+.
+.\" HTML <a name="lookbehind"></a>
+.SS "Lookbehind assertions"
+.rs
+.sp
+Lookbehind assertions start with (?<= for positive assertions and (?<! for
+negative assertions. For example,
+.sp
+ (?<!foo)bar
+.sp
+does find an occurrence of "bar" that is not preceded by "foo". The contents of
+a lookbehind assertion are restricted such that all the strings it matches must
+have a fixed length. However, if there are several top-level alternatives, they
+do not all have to have the same fixed length. Thus
+.sp
+ (?<=bullock|donkey)
+.sp
+is permitted, but
+.sp
+ (?<!dogs?|cats?)
+.sp
+causes an error at compile time. Branches that match different length strings
+are permitted only at the top level of a lookbehind assertion. This is an
+extension compared with Perl, which requires all branches to match the same
+length of string. An assertion such as
+.sp
+ (?<=ab(c|de))
+.sp
+is not permitted, because its single top-level branch can match two different
+lengths, but it is acceptable to PCRE2 if rewritten to use two top-level
+branches:
+.sp
+ (?<=abc|abde)
+.sp
+In some cases, the escape sequence \eK
+.\" HTML <a href="#resetmatchstart">
+.\" </a>
+(see above)
+.\"
+can be used instead of a lookbehind assertion to get round the fixed-length
+restriction.
+.P
+The implementation of lookbehind assertions is, for each alternative, to
+temporarily move the current position back by the fixed length and then try to
+match. If there are insufficient characters before the current position, the
+assertion fails.
+.P
+In a UTF mode, PCRE2 does not allow the \eC escape (which matches a single code
+unit even in a UTF mode) to appear in lookbehind assertions, because it makes
+it impossible to calculate the length of the lookbehind. The \eX and \eR
+escapes, which can match different numbers of code units, are also not
+permitted.
+.P
+.\" HTML <a href="#subpatternsassubroutines">

+as the subpattern matches a fixed-length string.
+.\" HTML <a href="#recursion">
+.\" </a>
+Recursion,
+.\"
+however, is not supported.
+.P
+Possessive quantifiers can be used in conjunction with lookbehind assertions to
+specify efficient matching of fixed-length strings at the end of subject
+strings. Consider a simple pattern such as
+.sp
+ abcd$
+.sp
+when applied to a long string that does not match. Because matching proceeds
+from left to right, PCRE2 will look for each "a" in the subject and then see if
+what follows matches the rest of the pattern. If the pattern is specified as
+.sp
+ ^.*abcd$
+.sp
+the initial .* matches the entire string at first, but when this fails (because
+there is no following "a"), it backtracks to match all but the last character,
+then all but the last two characters, and so on. Once again the search for "a"
+covers the entire string, from right to left, so we are no better off. However,
+if the pattern is written as
+.sp
+ ^.*+(?<=abcd)
+.sp
+there can be no backtracking for the .*+ item because of the possessive
+quantifier; it can match only the entire string. The subsequent lookbehind
+assertion does a single test on the last four characters. If it fails, the
+match fails immediately. For long strings, this approach makes a significant
+difference to the processing time.
+.
+.
+.SS "Using multiple assertions"
+.rs
+.sp
+Several assertions (of any sort) may occur in succession. For example,
+.sp
+ (?<=\ed{3})(?<!999)foo
+.sp
+matches "foo" preceded by three digits that are not "999". Notice that each of
+the assertions is applied independently at the same point in the subject
+string. First there is a check that the previous three characters are all
+digits, and then there is a check that the same three characters are not "999".
+This pattern does \fInot\fP match "foo" preceded by six characters, the first
+of which are digits and the last three of which are not "999". For example, it
+doesn't match "123abcfoo". A pattern to do that is
+.sp
+ (?<=\ed{3}...)(?<!999)foo
+.sp
+This time the first assertion looks at the preceding six characters, checking
+that the first three are digits, and then the second assertion checks that the
+preceding three characters are not "999".
+.P
+Assertions can be nested in any combination. For example,
+.sp
+ (?<=(?<!foo)bar)baz
+.sp
+matches an occurrence of "baz" that is preceded by "bar" which in turn is not
+preceded by "foo", while
+.sp
+ (?<=\ed{3}(?!999)...)foo
+.sp
+is another pattern that matches "foo" preceded by three digits and any three
+characters that are not "999".

+It is possible to cause the matching process to obey a subpattern

+already been matched. The two possible forms of conditional subpattern are:
+.sp
+ (?(condition)yes-pattern)
+ (?(condition)yes-pattern|no-pattern)
+.sp
+If the condition is satisfied, the yes-pattern is used; otherwise the
+no-pattern (if present) is used. If there are more than two alternatives in the
+subpattern, a compile-time error occurs. Each of the two alternatives may
+itself contain nested subpatterns of any form, including conditional
+subpatterns; the restriction to two alternatives applies only at the level of
+the condition. This pattern fragment is an example where the alternatives are
+complex:
+.sp
+ (?(1) (A|B|C) | (D | (?(2)E|F) | E) )

+the condition is true if any of them have matched. An alternative notation is

+number is relative rather than absolute. The most recently opened parentheses
+can be referenced by (?(-1), the next most recent by (?(-2), and so on. Inside
+loops it can also make sense to refer to subsequent groups. The next
+parentheses to be opened can be referenced as (?(+1), and so on. (The value
+zero in any of these forms is not used; it provokes a compile-time error.)
+.P
+Consider the following pattern, which contains non-significant white space to
+make it more readable (assume the PCRE2_EXTENDED option) and to divide it into
+three parts for ease of discussion:
+.sp
+ ( \e( )? [^()]+ (?(1) \e) )
+.sp
+The first part matches an optional opening parenthesis, and if that
+character is present, sets it as the first captured substring. The second part
+matches one or more characters that are not parentheses. The third part is a
+conditional subpattern that tests whether or not the first set of parentheses
+matched. If they did, that is, if subject started with an opening parenthesis,
+the condition is true, and so the yes-pattern is executed and a closing
+parenthesis is required. Otherwise, since no-pattern is not present, the
+subpattern matches nothing. In other words, this pattern matches a sequence of
+non-parentheses, optionally enclosed in parentheses.
+.P
+If you were embedding this pattern in a larger one, you could use a relative
+reference:

+ ...other stuff... ( \e( )? [^()]+ (?(-1) \e) ) ...
+.sp
+This makes the fragment independent of the parentheses in the larger pattern.
+.
+.

+.P
+Rewriting the above example to use a named subpattern gives this:

+For example:

+.sp
+ (?(?=[^a-z]*[a-z])
+ \ed{2}-[a-z]{3}-\ed{2} | \ed{2}-\ed{2}-\ed{2} )
+.sp
+The condition is a positive lookahead assertion that matches an optional
+sequence of non-letters followed by a letter. In other words, it tests for the
+presence of at least one letter in the subject. If a letter is found, the
+subject is matched against the first alternative; otherwise it is matched

+.\" HTML <a name="comments"></a>
+.SH COMMENTS
+.rs
+.sp
+There are two ways of including comments in patterns that are processed by

+class, nor in the middle of any other sequence of related characters such as
+(?: or a subpattern name or number. The characters that make up a comment play
+no part in the pattern matching.
+.P
+The sequence (?# marks the start of a comment that continues up to the next
+closing parenthesis. Nested parentheses are not permitted. If the
+PCRE2_EXTENDED option is set, an unescaped # character also introduces a
+comment, which in this case continues to immediately after the next newline
+character or character sequence in the pattern. Which characters are
+interpreted as newlines is controlled by an option passed to the compiling
+function or by a special sequence at the start of the pattern, as described in
+the section entitled
+.\" HTML <a href="#newlines">
+.\" </a>
+"Newline conventions"
+.\"
+above. Note that the end of this type of comment is a literal newline sequence
+in the pattern; escape sequences that happen to represent a newline do not
+count. For example, consider this pattern when PCRE2_EXTENDED is set, and the
+default newline convention (a single linefeed character) is in force:
+.sp
+ abc #comment \en still comment
+.sp
+On encountering the # character, \fBpcre2_compile()\fP skips along, looking for
+a newline in the pattern. The sequence \en is still literal at this stage, so
+it does not terminate the comment. Only an actual character with the code value
+0x0a (the default newline) does so.

+.\" HTML <a name="recursion"></a>
+.SH "RECURSIVE PATTERNS"
+.rs
+.sp
+Consider the problem of matching a string in parentheses, allowing for
+unlimited nested parentheses. Without the use of recursion, the best that can
+be done is to use a pattern that matches up to some fixed depth of nesting. It
+is not possible to handle an arbitrary nesting depth.
+.P
+For some time, Perl has provided a facility that allows regular expressions to
+recurse (amongst other things). It does this by interpolating Perl code in the
+expression at run time, and the code can refer to the expression itself. A Perl
+pattern using code interpolation to solve the parentheses problem can be
+created like this:
+.sp
+ $re = qr{\e( (?: (?>[^()]+) | (?p{$re}) )* \e)}x;
+.sp
+The (?p{...}) item interpolates Perl code at run time, and in this case refers
+recursively to the pattern in which it appears.
+.P
+Obviously, PCRE2 cannot support the interpolation of Perl code. Instead, it
+supports special syntax for recursion of the entire pattern, and also for
+individual subpattern recursion. After its introduction in PCRE1 and Python,
+this kind of recursion was subsequently introduced into Perl at release 5.10.
+.P
+A special item that consists of (? followed by a number greater than zero and a
+closing parenthesis is a recursive subroutine call of the subpattern of the
+given number, provided that it occurs inside that subpattern. (If not, it is a
+.\" HTML <a href="#subpatternsassubroutines">
+.\" </a>
+non-recursive subroutine
+.\"
+call, which is described in the next section.) The special item (?R) or (?0) is
+a recursive call of the entire regular expression.
+.P
+This PCRE2 pattern solves the nested parentheses problem (assume the
+PCRE2_EXTENDED option is set so that white space is ignored):
+.sp
+ \e( ( [^()]++ | (?R) )* \e)
+.sp
+First it matches an opening parenthesis. Then it matches any number of
+substrings which can either be a sequence of non-parentheses, or a recursive
+match of the pattern itself (that is, a correctly parenthesized substring).
+Finally there is a closing parenthesis. Note the use of a possessive quantifier
+to avoid backtracking into sequences of non-parentheses.
+.P
+If this were part of a larger pattern, you would not want to recurse the entire
+pattern, so instead you could use this:
+.sp
+ ( \e( ( [^()]++ | (?1) )* \e) )
+.sp
+We have put the pattern into parentheses, and caused the recursion to refer to
+them instead of the whole pattern.
+.P
+In a larger pattern, keeping track of parenthesis numbers can be tricky. This
+is made easier by the use of relative references. Instead of (?1) in the
+pattern above you can write (?-2) to refer to the second most recently opened
+parentheses preceding the recursion. In other words, a negative number counts
+capturing parentheses leftwards from the point at which it is encountered.
+.P
+Be aware however, that if
+.\" HTML <a href="#dupsubpatternnumber">
+.\" </a>

+are in use, relative references refer to the earliest subpattern with the
+appropriate number. Consider, for example:

+The first two capturing groups (a) and (b) are both numbered 1, and group (c)
+is number 2. When the reference (?-2) is encountered, the second most recently
+opened parentheses has the number 1, but it is the first such group (the (a)
+group) to which the recursion refers. This would be the same if an absolute
+reference (?1) was used. In other words, relative references are just a
+shorthand for computing a group number.
+.P
+It is also possible to refer to subsequently opened parentheses, by writing
+references such as (?+2). However, these cannot be recursive because the
+reference is not inside the parentheses that are referenced. They are always

+non-recursive subroutine
+.\"
+calls, as described in the next section.
+.P
+An alternative approach is to use named parentheses. The Perl syntax for this
+is (?&name); PCRE1's earlier syntax (?P>name) is also supported. We could
+rewrite the above example as follows:
+.sp
+ (?<pn> \e( ( [^()]++ | (?&pn) )* \e) )
+.sp
+If there is more than one subpattern with the same name, the earliest one is
+used.
+.P
+The example pattern that we have been looking at contains nested unlimited
+repeats, and so the use of a possessive quantifier for matching strings of
+non-parentheses is important when applying the pattern to strings that do not
+match. For example, when this pattern is applied to
+.sp
+ (aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa()
+.sp
+it yields "no match" quickly. However, if a possessive quantifier is not used,
+the match runs for a very long time indeed because there are so many different
+ways the + and * repeats can carve up the subject, and all have to be tested
+before failure can be reported.
+.P
+At the end of a match, the values of capturing parentheses are those from
+the outermost level. If you want to obtain intermediate values, a callout
+function can be used (see below and the
+.\" HREF
+\fBpcre2callout\fP
+.\"
+documentation). If the pattern above is matched against
+.sp
+ (ab(cd)ef)
+.sp
+the value for the inner capturing parentheses (numbered 2) is "ef", which is
+the last value taken on at the top level. If a capturing subpattern is not
+matched at the top level, its final captured value is unset, even if it was
+(temporarily) set at a deeper level during the matching process.
+.P
+If there are more than 15 capturing parentheses in a pattern, PCRE2 has to
+obtain extra memory from the heap to store data during a recursion. If no
+memory can be obtained, the match fails with the PCRE2_ERROR_NOMEMORY error.
+.P
+Do not confuse the (?R) item with the condition (R), which tests for recursion.
+Consider this pattern, which matches text in angle brackets, allowing for
+arbitrary nesting. Only digits are allowed in nested brackets (that is, when
+recursing), whereas any characters are permitted at the outer level.
+.sp
+ < (?: (?(R) \ed++ | [^<>]*+) | (?R)) * >
+.sp
+In this pattern, (?(R) is the start of a conditional subpattern, with two
+different alternatives for the recursive and non-recursive cases. The (?R) item
+is the actual recursive call.

+.\" HTML <a name="recursiondifference"></a>
+.SS "Differences in recursion processing between PCRE2 and Perl"
+.rs
+.sp
+Recursion processing in PCRE2 differs from Perl in two important ways. In PCRE2
+(like Python, but unlike Perl), a recursive subpattern call is always treated
+as an atomic group. That is, once it has matched some of the subject string, it
+is never re-entered, even if it contains untried alternatives and there is a
+subsequent matching failure. This can be illustrated by the following pattern,
+which purports to match a palindromic string that contains an odd number of
+characters (for example, "a", "aba", "abcba", "abcdcba"):
+.sp
+ ^(.|(.)(?1)\e2)$
+.sp
+The idea is that it either matches a single character, or two identical
+characters surrounding a sub-palindrome. In Perl, this pattern works; in PCRE2
+it does not if the pattern is longer than three characters. Consider the
+subject string "abcba":
+.P
+At the top level, the first character is matched, but as it is not at the end
+of the string, the first alternative fails; the second alternative is taken
+and the recursion kicks in. The recursive call to subpattern 1 successfully
+matches the next character ("b"). (Note that the beginning and end of line
+tests are not part of the recursion).
+.P
+Back at the top level, the next character ("c") is compared with what
+subpattern 2 matched, which was "a". This fails. Because the recursion is
+treated as an atomic group, there are now no backtracking points, and so the
+entire match fails. (Perl is able, at this point, to re-enter the recursion and
+try the second alternative.) However, if the pattern is written with the
+alternatives in the other order, things are different:
+.sp
+ ^((.)(?1)\e2|.)$
+.sp
+This time, the recursing alternative is tried first, and continues to recurse
+until it runs out of characters, at which point the recursion fails. But this
+time we do have another alternative to try at the higher level. That is the big
+difference: in the previous case the remaining alternative is at a deeper
+recursion level, which PCRE2 cannot use.
+.P
+To change the pattern so that it matches all palindromic strings, not just
+those with an odd number of characters, it is tempting to change the pattern to
+this:
+.sp
+ ^((.)(?1)\e2|.?)$
+.sp
+Again, this works in Perl, but not in PCRE2, and for the same reason. When a
+deeper recursion has matched a single character, it cannot be entered again in
+order to match an empty string. The solution is to separate the two cases, and
+write out the odd and even cases as alternatives at the higher level:
+.sp
+ ^(?:((.)(?1)\e2|)|((.)(?3)\e4|.))
+.sp
+If you want to match typical palindromic phrases, the pattern has to ignore all
+non-word characters, which can be done like this:
+.sp
+ ^\eW*+(?:((.)\eW*+(?1)\eW*+\e2|)|((.)\eW*+(?3)\eW*+\e4|\eW*+.\eW*+))\eW*+$
+.sp
+If run with the PCRE2_CASELESS option, this pattern matches phrases such as "A
+man, a plan, a canal: Panama!" and it works in both PCRE2 and Perl. Note the
+use of the possessive quantifier *+ to avoid backtracking into sequences of
+non-word characters. Without this, PCRE2 takes a great deal longer (ten times
+or more) to match typical phrases, and Perl takes so long that you think it has
+gone into a loop.
+.P
+\fBWARNING\fP: The palindrome-matching patterns above work only if the subject
+string does not start with a palindrome that is shorter than the entire string.
+For example, although "abcba" is correctly matched, if the subject is "ababa",
+PCRE2 finds the palindrome "aba" at the start, then fails at top level because
+the end of the string does not follow. Once again, it cannot jump back into the
+recursion to try other alternatives, so the entire match fails.
+.P
+The second way in which PCRE2 and Perl differ in their recursion processing is
+in the handling of captured values. In Perl, when a subpattern is called
+recursively or as a subpattern (see the next section), it has no access to any
+values that were captured outside the recursion, whereas in PCRE2 these values
+can be referenced. Consider this pattern:
+.sp
+ ^(.)(\e1|a(?2))
+.sp
+In PCRE2, this pattern matches "bab". The first capturing parentheses match "b",
+then in the second group, when the back reference \e1 fails to match "b", the
+second alternative matches "a" and then recurses. In the recursion, \e1 does
+now match "b" and so the whole match succeeds. In Perl, the pattern fails to
+match because inside the recursive call \e1 cannot access the externally set
+value.
+.
+.
+.\" HTML <a name="subpatternsassubroutines"></a>
+.SH "SUBPATTERNS AS SUBROUTINES"
+.rs
+.sp
+If the syntax for a recursive subpattern call (either by number or by
+name) is used outside the parentheses to which it refers, it operates like a
+subroutine in a programming language. The called subpattern may be defined
+before or after the reference. A numbered reference can be absolute or
+relative, as in these examples:
+.sp
+ (...(absolute)...)...(?2)...
+ (...(relative)...)...(?-1)...
+ (...(?+1)...(relative)...
+.sp
+An earlier example pointed out that the pattern
+.sp
+ (sens|respons)e and \e1ibility
+.sp
+matches "sense and sensibility" and "response and responsibility", but not
+"sense and responsibility". If instead the pattern
+.sp
+ (sens|respons)e and (?1)ibility
+.sp
+is used, it does match "sense and responsibility" as well as the other two
+strings. Another example is given in the discussion of DEFINE above.
+.P
+All subroutine calls, whether recursive or not, are always treated as atomic
+groups. That is, once a subroutine has matched some of the subject string, it
+is never re-entered, even if it contains untried alternatives and there is a
+subsequent matching failure. Any capturing parentheses that are set during the
+subroutine call revert to their previous values afterwards.
+.P
+Processing options such as case-independence are fixed when a subpattern is
+defined, so if it is used as a subroutine, such options cannot be changed for
+different calls. For example, consider this pattern:
+.sp
+ (abc)(?i:(?-1))
+.sp
+It matches "abcabc". It does not match "abcABC" because the change of
+processing option does not affect the called subpattern.
+.

+For compatibility with Oniguruma, the non-Perl syntax \eg followed by a name or

+syntax for referencing a subpattern as a subroutine, possibly recursively. Here

+.sp
+ (?<pn> \e( ( (?>[^()]+) | \eg<pn> )* \e) )
+ (sens|respons)e and \eg'1'ibility

+PCRE2 supports an extension to Oniguruma: if a number is preceded by a

+ (abc)(?i:\eg<-1>)
+.sp
+Note that \eg{...} (Perl syntax) and \eg<...> (Oniguruma syntax) are \fInot\fP
+synonymous. The former is a back reference; the latter is a subroutine call.
+.
+.
+.SH CALLOUTS
+.rs
+.sp
+Perl has a feature whereby using the sequence (?{...}) causes arbitrary Perl
+code to be obeyed in the middle of matching a regular expression. This makes it
+possible, amongst other things, to extract different substrings that match the
+same pair of parentheses when there is a repetition.
+.P
+PCRE2 provides a similar feature, but of course it cannot obey arbitrary Perl
+code. The feature is called "callout". The caller of PCRE2 provides an external
+function by putting its entry point in a match context using the function
+\fBpcre2_set_callout()\fP, and then passing that context to \fBpcre2_match()\fP
+or \fBpcre2_dfa_match()\fP. If no match context is passed, or if the callout
+entry point is set to NULL, callouts are disabled.
+.P
+Within a regular expression, (?C<arg>) indicates a point at which the external
+function is to be called. There are two kinds of callout: those with a
+numerical argument and those with a string argument. (?C) on its own with no
+argument is treated as (?C0). A numerical argument allows the application to
+distinguish between different callouts. String arguments were added for release
+10.20 to make it possible for script languages that use PCRE2 to embed short
+scripts within patterns in a similar way to Perl.
+.P
+During matching, when PCRE2 reaches a callout point, the external function is
+called. It is provided with the number or string argument of the callout, the
+position in the pattern, and one item of data that is also set in the match
+block. The callout function may cause matching to proceed, to backtrack, or to
+fail.
+.P
+By default, PCRE2 implements a number of optimizations at matching time, and
+one side-effect is that sometimes callouts are skipped. If you need all
+possible callouts to happen, you need to set options that disable the relevant
+optimizations. More details, including a complete description of the
+programming interface to the callout function, are given in the
+.\" HREF
+\fBpcre2callout\fP

+documentation.
+.
+.
+.SS "Callouts with numerical arguments"
+.rs
+.sp
+If you just want to have a means of identifying different callout points, put a
+number less than 256 after the letter C. For example, this pattern has two
+callout points:
+.sp
+ (?C1)abc(?C2)def
+.sp
+If the PCRE2_AUTO_CALLOUT flag is passed to \fBpcre2_compile()\fP, numerical
+callouts are automatically installed before each item in the pattern. They are
+all numbered 255. If there is a conditional group in the pattern whose
+condition is an assertion, an additional callout is inserted just before the
+condition. An explicit callout may also be set at this position, as in this
+example:
+.sp
+ (?(?C9)(?=a)abc|def)
+.sp
+Note that this applies only to assertion conditions, not to other types of
+condition.
+.
+.
+.SS "Callouts with string arguments"
+.rs
+.sp
+A delimited string may be used instead of a number as a callout argument. The
+starting delimiter must be one of ` ' " ^ % # $ { and the ending delimiter is
+the same as the start, except for {, where the ending delimiter is }. If the
+ending delimiter is needed within the string, it must be doubled. For
+example:
+.sp
+ (?C'ab ''c'' d')xyz(?C{any text})pqr
+.sp
+The doubling is removed before the string is passed to the callout function.

+.\" HTML <a name="backtrackcontrol"></a>
+.SH "BACKTRACKING CONTROL"
+.rs
+.sp
+Perl 5.10 introduced a number of "Special Backtracking Control Verbs", which
+are still described in the Perl documentation as "experimental and subject to
+change or removal in a future version of Perl". It goes on to say: "Their usage
+in production code should be noted to avoid problems during upgrades." The same
+remarks apply to the PCRE2 features described in this section.
+.P
+The new verbs make use of what was previously invalid syntax: an opening
+parenthesis followed by an asterisk. They are generally of the form (*VERB) or
+(*VERB:NAME). Some verbs take either form, possibly behaving differently
+depending on whether or not a name is present.
+.P
+By default, for compatibility with Perl, a name is any sequence of characters
+that does not include a closing parenthesis. The name is not processed in
+any way, and it is not possible to include a closing parenthesis in the name.
+However, if the PCRE2_ALT_VERBNAMES option is set, normal backslash processing
+is applied to verb names and only an unescaped closing parenthesis terminates
+the name. A closing parenthesis can be included in a name either as \e) or
+between \eQ and \eE. If the PCRE2_EXTENDED option is set, unescaped whitespace
+in verb names is skipped and #-comments are recognized, exactly as in the rest
+of the pattern.
+.P
+The maximum length of a name is 255 in the 8-bit library and 65535 in the
+16-bit and 32-bit libraries. If the name is empty, that is, if the closing
+parenthesis immediately follows the colon, the effect is as if the colon were
+not there. Any number of these verbs may occur in a pattern.
+.P
+Since these verbs are specifically related to backtracking, most of them can be
+used only when the pattern is to be matched using the traditional matching
+function, because these use a backtracking algorithm. With the exception of
+(*FAIL), which behaves like a failing negative assertion, the backtracking
+control verbs cause an error if encountered by the DFA matching function.

+included backtracking verbs will not, of course, be processed. You can suppress
+the start-of-match optimizations by setting the PCRE2_NO_START_OPTIMIZE option

+.SS "Verbs that act immediately"
+.rs
+.sp
+The following verbs act as soon as they are encountered. They may not be
+followed by a name.
+.sp
+ (*ACCEPT)
+.sp
+This verb causes the match to end successfully, skipping the remainder of the
+pattern. However, when it is inside a subpattern that is called as a
+subroutine, only that subpattern is ended successfully. Matching then continues
+at the outer level. If (*ACCEPT) in triggered in a positive assertion, the
+assertion succeeds; in a negative assertion, the assertion fails.
+.P
+If (*ACCEPT) is inside capturing parentheses, the data so far is captured. For
+example:
+.sp
+ A((?:A|B(*ACCEPT)|C)D)
+.sp
+This matches "AB", "AAD", or "ACD"; when it matches "AB", "B" is captured by
+the outer parentheses.
+.sp
+ (*FAIL) or (*F)
+.sp
+This verb causes a matching failure, forcing backtracking to occur. It is
+equivalent to (?!) but easier to read. The Perl documentation notes that it is
+probably useful only when combined with (?{}) or (??{}). Those are, of course,
+Perl features that are not present in PCRE2. The nearest equivalent is the
+callout feature, as for example in this pattern:
+.sp
+ a+(?C)(*FAIL)
+.sp
+A match with the string "aaaa" always fails, but the callout is taken before
+each backtrack happens (in this example, 10 times).
+.
+.
+.SS "Recording which path was taken"
+.rs
+.sp
+There is one verb whose main purpose is to track how a match was arrived at,
+though it also has a secondary use in conjunction with advancing the match
+starting point (see (*SKIP) below).
+.sp
+ (*MARK:NAME) or (*:NAME)
+.sp
+A name is always required with this verb. There may be as many instances of
+(*MARK) as you like in a pattern, and their names do not have to be unique.
+.P
+When a match succeeds, the name of the last-encountered (*MARK:NAME),
+(*PRUNE:NAME), or (*THEN:NAME) on the matching path is passed back to the
+caller as described in the section entitled
+.\" HTML <a href="pcre2api.html#matchotherdata">
+.\" </a>
+"Other information about the match"
+.\"
+in the
+.\" HREF
+\fBpcre2api\fP

+documentation. Here is an example of \fBpcre2test\fP output, where the "mark"
+modifier requests the retrieval and outputting of (*MARK) data:
+.sp
+ re> /X(*MARK:A)Y|X(*MARK:B)Z/mark
+ data> XY
+ 0: XY
+ MK: A
+ XZ
+ 0: XZ
+ MK: B
+.sp
+The (*MARK) name is tagged with "MK:" in this output, and in this example it
+indicates which of the two alternatives matched. This is a more efficient way
+of obtaining this information than putting each alternative in its own
+capturing parentheses.
+.P
+If a verb with a name is encountered in a positive assertion that is true, the
+name is recorded and passed back if it is the last-encountered. This does not
+happen for negative assertions or failing positive assertions.
+.P
+After a partial match or a failed match, the last encountered name in the
+entire match process is returned. For example:
+.sp
+ re> /X(*MARK:A)Y|X(*MARK:B)Z/mark
+ data> XP
+ No match, mark = B
+.sp
+Note that in this unanchored example the mark is retained from the match
+attempt that started at the letter "X" in the subject. Subsequent match
+attempts starting at "P" and then with an empty string do not get as far as the
+(*MARK) item, but nevertheless do not reset it.
+.P
+If you are interested in (*MARK) values after failed matches, you should
+probably set the PCRE2_NO_START_OPTIMIZE option
+.\" HTML <a href="#nooptimize">

+to ensure that the match is always attempted.
+.
+.
+.SS "Verbs that act after backtracking"
+.rs
+.sp
+The following verbs do nothing when they are encountered. Matching continues
+with what follows, but if there is no subsequent match, causing a backtrack to
+the verb, a failure is forced. That is, backtracking cannot pass to the left of
+the verb. However, when one of these verbs appears inside an atomic group
+(which includes any group that is called as a subroutine) or in an assertion
+that is true, its effect is confined to that group, because once the group has
+been matched, there is never any backtracking into it. In this situation,
+backtracking has to jump to the left of the entire atomic group or assertion.
+.P
+These verbs differ in exactly what kind of failure occurs when backtracking
+reaches them. The behaviour described below is what happens when the verb is
+not in a subroutine or an assertion. Subsequent sections cover these special
+cases.
+.sp
+ (*COMMIT)
+.sp
+This verb, which may not be followed by a name, causes the whole match to fail
+outright if there is a later matching failure that causes backtracking to reach
+it. Even if the pattern is unanchored, no further attempts to find a match by
+advancing the starting point take place. If (*COMMIT) is the only backtracking
+verb that is encountered, once it has been passed \fBpcre2_match()\fP is
+committed to finding a match at the current starting point, or not at all. For
+example:
+.sp
+ a+(*COMMIT)b
+.sp
+This matches "xxaab" but not "aacaab". It can be thought of as a kind of
+dynamic anchor, or "I've started, so I must finish." The name of the most
+recently passed (*MARK) in the path is passed back when (*COMMIT) forces a
+match failure.
+.P
+If there is more than one backtracking verb in a pattern, a different one that
+follows (*COMMIT) may be triggered first, so merely passing (*COMMIT) during a
+match does not always guarantee that a match must be at this starting point.
+.P
+Note that (*COMMIT) at the start of a pattern is not the same as an anchor,
+unless PCRE2's start-of-match optimizations are turned off, as shown in this
+output from \fBpcre2test\fP:
+.sp
+ re> /(*COMMIT)abc/
+ data> xyzabc
+ 0: abc
+ data>
+ re> /(*COMMIT)abc/no_start_optimize
+ data> xyzabc
+ No match
+.sp
+For the first pattern, PCRE2 knows that any match must start with "a", so the
+optimization skips along the subject to "a" before applying the pattern to the
+first set of data. The match attempt then succeeds. The second pattern disables
+the optimization that skips along to the first character. The pattern is now
+applied starting at "x", and so the (*COMMIT) causes the match to fail without
+trying any other starting points.
+.sp
+ (*PRUNE) or (*PRUNE:NAME)
+.sp
+This verb causes the match to fail at the current starting position in the
+subject if there is a later matching failure that causes backtracking to reach
+it. If the pattern is unanchored, the normal "bumpalong" advance to the next
+starting character then happens. Backtracking can occur as usual to the left of
+(*PRUNE), before it is reached, or when matching to the right of (*PRUNE), but
+if there is no match to the right, backtracking cannot cross (*PRUNE). In
+simple cases, the use of (*PRUNE) is just an alternative to an atomic group or
+possessive quantifier, but there are some uses of (*PRUNE) that cannot be
+expressed in any other way. In an anchored pattern (*PRUNE) has the same effect
+as (*COMMIT).
+.P
+The behaviour of (*PRUNE:NAME) is the not the same as (*MARK:NAME)(*PRUNE).
+It is like (*MARK:NAME) in that the name is remembered for passing back to the
+caller. However, (*SKIP:NAME) searches only for names set with (*MARK),
+ignoring those set by (*PRUNE) or (*THEN).
+.sp
+ (*SKIP)
+.sp
+This verb, when given without a name, is like (*PRUNE), except that if the
+pattern is unanchored, the "bumpalong" advance is not to the next character,
+but to the position in the subject where (*SKIP) was encountered. (*SKIP)
+signifies that whatever text was matched leading up to it cannot be part of a
+successful match. Consider:
+.sp
+ a+(*SKIP)b
+.sp
+If the subject is "aaaac...", after the first match attempt fails (starting at
+the first character in the string), the starting point skips on to start the
+next attempt at "c". Note that a possessive quantifer does not have the same
+effect as this example; although it would suppress backtracking during the
+first match attempt, the second attempt would start at the second character
+instead of skipping on to "c".
+.sp
+ (*SKIP:NAME)
+.sp
+When (*SKIP) has an associated name, its behaviour is modified. When it is
+triggered, the previous path through the pattern is searched for the most
+recent (*MARK) that has the same name. If one is found, the "bumpalong" advance
+is to the subject position that corresponds to that (*MARK) instead of to where
+(*SKIP) was encountered. If no (*MARK) with a matching name is found, the
+(*SKIP) is ignored.
+.P
+Note that (*SKIP:NAME) searches only for names set by (*MARK:NAME). It ignores
+names that are set by (*PRUNE:NAME) or (*THEN:NAME).
+.sp
+ (*THEN) or (*THEN:NAME)
+.sp
+This verb causes a skip to the next innermost alternative when backtracking
+reaches it. That is, it cancels any further backtracking within the current
+alternative. Its name comes from the observation that it can be used for a
+pattern-based if-then-else block:
+.sp
+ ( COND1 (*THEN) FOO | COND2 (*THEN) BAR | COND3 (*THEN) BAZ ) ...
+.sp
+If the COND1 pattern matches, FOO is tried (and possibly further items after
+the end of the group if FOO succeeds); on failure, the matcher skips to the
+second alternative and tries COND2, without backtracking into COND1. If that
+succeeds and BAR fails, COND3 is tried. If subsequently BAZ fails, there are no
+more alternatives, so there is a backtrack to whatever came before the entire
+group. If (*THEN) is not inside an alternation, it acts like (*PRUNE).
+.P
+The behaviour of (*THEN:NAME) is the not the same as (*MARK:NAME)(*THEN).
+It is like (*MARK:NAME) in that the name is remembered for passing back to the
+caller. However, (*SKIP:NAME) searches only for names set with (*MARK),
+ignoring those set by (*PRUNE) and (*THEN).
+.P
+A subpattern that does not contain a | character is just a part of the
+enclosing alternative; it is not a nested alternation with only one
+alternative. The effect of (*THEN) extends beyond such a subpattern to the
+enclosing alternative. Consider this pattern, where A, B, etc. are complex
+pattern fragments that do not contain any | characters at this level:
+.sp
+ A (B(*THEN)C) | D
+.sp
+If A and B are matched, but there is a failure in C, matching does not
+backtrack into A; instead it moves to the next alternative, that is, D.
+However, if the subpattern containing (*THEN) is given an alternative, it
+behaves differently:
+.sp
+ A (B(*THEN)C | (*FAIL)) | D
+.sp
+The effect of (*THEN) is now confined to the inner subpattern. After a failure
+in C, matching moves to (*FAIL), which causes the whole subpattern to fail
+because there are no more alternatives to try. In this case, matching does now
+backtrack into A.
+.P
+Note that a conditional subpattern is not considered as having two
+alternatives, because only one is ever used. In other words, the | character in
+a conditional subpattern has a different meaning. Ignoring white space,
+consider:
+.sp
+ ^.*? (?(?=a) a | b(*THEN)c )
+.sp
+If the subject is "ba", this pattern does not match. Because .*? is ungreedy,
+it initially matches zero characters. The condition (?=a) then fails, the
+character "b" is matched, but "c" is not. At this point, matching does not
+backtrack to .*? as might perhaps be expected from the presence of the |
+character. The conditional subpattern is part of the single alternative that
+comprises the whole pattern, and so the match fails. (If there was a backtrack
+into .*?, allowing it to match "b", the match would succeed.)
+.P
+The verbs just described provide four different "strengths" of control when
+subsequent matching fails. (*THEN) is the weakest, carrying on the match at the
+next alternative. (*PRUNE) comes next, failing the match at the current
+starting position, but allowing an advance to the next character (for an
+unanchored pattern). (*SKIP) is similar, except that the advance may be more
+than one character. (*COMMIT) is the strongest, causing the entire match to
+fail.
+.
+.
+.SS "More than one backtracking verb"
+.rs
+.sp
+If more than one backtracking verb is present in a pattern, the one that is
+backtracked onto first acts. For example, consider this pattern, where A, B,
+etc. are complex pattern fragments:
+.sp
+ (A(*COMMIT)B(*THEN)C|ABD)
+.sp
+If A matches but B fails, the backtrack to (*COMMIT) causes the entire match to
+fail. However, if A and B match, but C fails, the backtrack to (*THEN) causes
+the next alternative (ABD) to be tried. This behaviour is consistent, but is
+not always the same as Perl's. It means that if two or more backtracking verbs
+appear in succession, all the the last of them has no effect. Consider this
+example:
+.sp
+ ...(*COMMIT)(*PRUNE)...
+.sp
+If there is a matching failure to the right, backtracking onto (*PRUNE) causes
+it to be triggered, and its action is taken. There can never be a backtrack
+onto (*COMMIT).
+.
+.
+.\" HTML <a name="btrepeat"></a>
+.SS "Backtracking verbs in repeated groups"
+.rs
+.sp
+PCRE2 differs from Perl in its handling of backtracking verbs in repeated
+groups. For example, consider:
+.sp
+ /(a(*COMMIT)b)+ac/
+.sp
+If the subject is "abac", Perl matches, but PCRE2 fails because the (*COMMIT)
+in the second repeat of the group acts.
+.
+.
+.\" HTML <a name="btassert"></a>
+.SS "Backtracking verbs in assertions"
+.rs
+.sp
+(*FAIL) in an assertion has its normal effect: it forces an immediate
+backtrack.
+.P
+(*ACCEPT) in a positive assertion causes the assertion to succeed without any
+further processing. In a negative assertion, (*ACCEPT) causes the assertion to
+fail without any further processing.
+.P
+The other backtracking verbs are not treated specially if they appear in a
+positive assertion. In particular, (*THEN) skips to the next alternative in the
+innermost enclosing group that has alternations, whether or not this is within
+the assertion.
+.P
+Negative assertions are, however, different, in order to ensure that changing a
+positive assertion into a negative assertion changes its result. Backtracking
+into (*COMMIT), (*SKIP), or (*PRUNE) causes a negative assertion to be true,
+without considering any further alternative branches in the assertion.
+Backtracking into (*THEN) causes it to skip to the next enclosing alternative
+within the assertion (the normal behaviour), but if the assertion does not have
+such an alternative, (*THEN) behaves like (*PRUNE).
+.
+.
+.\" HTML <a name="btsub"></a>
+.SS "Backtracking verbs in subroutines"
+.rs
+.sp
+These behaviours occur whether or not the subpattern is called recursively.
+Perl's treatment of subroutines is different in some cases.
+.P
+(*FAIL) in a subpattern called as a subroutine has its normal effect: it forces
+an immediate backtrack.
+.P
+(*ACCEPT) in a subpattern called as a subroutine causes the subroutine match to
+succeed without any further processing. Matching then continues after the
+subroutine call.
+.P
+(*COMMIT), (*SKIP), and (*PRUNE) in a subpattern called as a subroutine cause
+the subroutine match to fail.
+.P
+(*THEN) skips to the next alternative in the innermost enclosing group within
+the subpattern that has alternatives. If there is no such group within the
+subpattern, (*THEN) causes the subroutine match to fail.

+.TH PCRE2PERFORM 3 "02 January 2015" "PCRE2 10.00"
+.SH NAME
+PCRE2 - Perl-compatible regular expressions (revised API)
+.SH "PCRE2 PERFORMANCE"
+.rs
+.sp
+Two aspects of performance are discussed below: memory usage and processing
+time. The way you express your pattern as a regular expression can affect both
+of them.
+.
+.SH "COMPILED PATTERN MEMORY USAGE"
+.rs
+.sp
+Patterns are compiled by PCRE2 into a reasonably efficient interpretive code,
+so that most simple patterns do not use much memory. However, there is one case
+where the memory usage of a compiled pattern can be unexpectedly large. If a
+parenthesized subpattern has a quantifier with a minimum greater than 1 and/or
+a limited maximum, the whole subpattern is repeated in the compiled code. For
+example, the pattern
+.sp
+ (abc|def){2,4}
+.sp
+is compiled as if it were
+.sp
+ (abc|def)(abc|def)((abc|def)(abc|def)?)?
+.sp
+(Technical aside: It is done this way so that backtrack points within each of
+the repetitions can be independently maintained.)
+.P
+For regular expressions whose quantifiers use only small numbers, this is not
+usually a problem. However, if the numbers are large, and particularly if such
+repetitions are nested, the memory usage can become an embarrassment. For
+example, the very simple pattern
+.sp
+ ((ab){1,1000}c){1,3}
+.sp
+uses 51K bytes when compiled using the 8-bit library. When PCRE2 is compiled
+with its default internal pointer size of two bytes, the size limit on a
+compiled pattern is 64K code units in the 8-bit and 16-bit libraries, and this
+is reached with the above pattern if the outer repetition is increased from 3
+to 4. PCRE2 can be compiled to use larger internal pointers and thus handle
+larger compiled patterns, but it is better to try to rewrite your pattern to
+use less memory if you can.
+.P
+One way of reducing the memory usage for such patterns is to make use of
+PCRE2's
+.\" HTML <a href="pcre2pattern.html#subpatternsassubroutines">
+.\" </a>
+"subroutine"
+.\"
+facility. Re-writing the above pattern as
+.sp
+ ((ab)(?2){0,999}c)(?1){0,2}
+.sp
+reduces the memory requirements to 18K, and indeed it remains under 20K even
+with the outer repetition increased to 100. However, this pattern is not
+exactly equivalent, because the "subroutine" calls are treated as
+.\" HTML <a href="pcre2pattern.html#atomicgroup">
+.\" </a>
+atomic groups
+.\"
+into which there can be no backtracking if there is a subsequent matching
+failure. Therefore, PCRE2 cannot do this kind of rewriting automatically.
+Furthermore, there is a noticeable loss of speed when executing the modified
+pattern. Nevertheless, if the atomic grouping is not a problem and the loss of
+speed is acceptable, this kind of rewriting will allow you to process patterns
+that PCRE2 cannot otherwise handle.
+.
+.
+.SH "STACK USAGE AT RUN TIME"
+.rs
+.sp
+When \fBpcre2_match()\fP is used for matching, certain kinds of pattern can
+cause it to use large amounts of the process stack. In some environments the
+default process stack is quite small, and if it runs out the result is often
+SIGSEGV. Rewriting your pattern can often help. The
+.\" HREF
+\fBpcre2stack\fP
+.\"
+documentation discusses this issue in detail.
+.
+.
+.SH "PROCESSING TIME"
+.rs
+.sp
+Certain items in regular expression patterns are processed more efficiently
+than others. It is more efficient to use a character class like [aeiou] than a
+set of single-character alternatives such as (a|e|i|o|u). In general, the
+simplest construction that provides the required behaviour is usually the most
+efficient. Jeffrey Friedl's book contains a lot of useful general discussion
+about optimizing regular expressions for efficient performance. This document
+contains a few observations about PCRE2.
+.P
+Using Unicode character properties (the \ep, \eP, and \eX escapes) is slow,
+because PCRE2 has to use a multi-stage table lookup whenever it needs a
+character's property. If you can find an alternative pattern that does not use
+character properties, it will probably be faster.
+.P
+By default, the escape sequences \eb, \ed, \es, and \ew, and the POSIX
+character classes such as [:alpha:] do not use Unicode properties, partly for
+backwards compatibility, and partly for performance reasons. However, you can
+set the PCRE2_UCP option or start the pattern with (*UCP) if you want Unicode
+character properties to be used. This can double the matching time for items
+such as \ed, when matched with \fBpcre2_match()\fP; the performance loss is
+less with a DFA matching function, and in both cases there is not much
+difference for \eb.
+.P
+When a pattern begins with .* not in atomic parentheses, nor in parentheses
+that are the subject of a backreference, and the PCRE2_DOTALL option is set,
+the pattern is implicitly anchored by PCRE2, since it can match only at the
+start of a subject string. If the pattern has multiple top-level branches, they
+must all be anchorable. The optimization can be disabled by the
+PCRE2_NO_DOTSTAR_ANCHOR option, and is automatically disabled if the pattern
+contains (*PRUNE) or (*SKIP).
+.P
+If PCRE2_DOTALL is not set, PCRE2 cannot make this optimization, because the
+dot metacharacter does not then match a newline, and if the subject string
+contains newlines, the pattern may match from the character immediately
+following one of them instead of from the very start. For example, the pattern
+.sp
+ .*second
+.sp
+matches the subject "first\enand second" (where \en stands for a newline
+character), with the match starting at the seventh character. In order to do
+this, PCRE2 has to retry the match starting after every newline in the subject.
+.P
+If you are using such a pattern with subject strings that do not contain
+newlines, the best performance is obtained by setting PCRE2_DOTALL, or starting
+the pattern with ^.* or ^.*? to indicate explicit anchoring. That saves PCRE2
+from having to scan along the subject looking for a newline to restart at.
+.P
+Beware of patterns that contain nested indefinite repeats. These can take a
+long time to run when applied to a string that does not match. Consider the
+pattern fragment
+.sp
+ ^(a+)*
+.sp
+This can match "aaaa" in 16 different ways, and this number increases very
+rapidly as the string gets longer. (The * repeat can match 0, 1, 2, 3, or 4
+times, and for each of those cases other than 0 or 4, the + repeats can match
+different numbers of times.) When the remainder of the pattern is such that the
+entire match is going to fail, PCRE2 has in principle to try every possible
+variation, and this can take an extremely long time, even for relatively short
+strings.
+.P
+An optimization catches some of the more simple cases such as
+.sp
+ (a+)*b
+.sp
+where a literal character follows. Before embarking on the standard matching
+procedure, PCRE2 checks that there is a "b" later in the subject string, and if
+there is not, it fails the match immediately. However, when there is no
+following literal this optimization cannot be used. You can see the difference
+by comparing the behaviour of
+.sp
+ (a+)*\ed
+.sp
+with the pattern above. The former gives a failure almost instantly when
+applied to a whole line of "a" characters, whereas the latter takes an
+appreciable time with strings longer than about 20 characters.
+.P
+In many cases, the solution to this kind of performance issue is to use an
+atomic group or a possessive quantifier.

+.SH DESCRIPTION
+.rs
+.sp
+This set of functions provides a POSIX-style API for the PCRE2 regular
+expression 8-bit library. See the
+.\" HREF
+\fBpcre2api\fP
+.\"
+documentation for a description of PCRE2's native API, which contains much
+additional functionality. There is no POSIX-style wrapper for PCRE2's 16-bit
+and 32-bit libraries.
+.P
+The functions described here are just wrapper functions that ultimately call
+the PCRE2 native API. Their prototypes are defined in the \fBpcre2posix.h\fP
+header file, and on Unix systems the library itself is called
+\fBlibpcre2-posix.a\fP, so can be accessed by adding \fB-lpcre2-posix\fP to the
+command for linking an application that uses them. Because the POSIX functions
+call the native ones, it is also necessary to add \fB-lpcre2-8\fP.
+.P
+Those POSIX option bits that can reasonably be mapped to PCRE2 native options
+have been implemented. In addition, the option REG_EXTENDED is defined with the
+value zero. This has no effect, but since programs that are written to the
+POSIX interface often use it, this makes it easier to slot in PCRE2 as a
+replacement library. Other POSIX options are not even defined.
+.P
+There are also some other options that are not defined by POSIX. These have
+been added at the request of users who want to make use of certain
+PCRE2-specific features via the POSIX calling interface.
+.P
+When PCRE2 is called via these functions, it is only the API that is POSIX-like
+in style. The syntax and semantics of the regular expressions themselves are
+still those of Perl, subject to the setting of various PCRE2 options, as
+described below. "POSIX-like in style" means that the API approximates to the
+POSIX definition; it is not fully POSIX-compatible, and in multi-unit encoding
+domains it is probably even less compatible.
+.P
+The header for these functions is supplied as \fBpcre2posix.h\fP to avoid any
+potential clash with other POSIX libraries. It can, of course, be renamed or
+aliased as \fBregex.h\fP, which is the "correct" name. It provides two
+structure types, \fIregex_t\fP for compiled internal forms, and
+\fIregmatch_t\fP for returning captured substrings. It also defines some
+constants whose names start with "REG_"; these are used for setting options and
+identifying error codes.
+.
+.
+.SH "COMPILING A PATTERN"
+.rs
+.sp
+The function \fBregcomp()\fP is called to compile a pattern into an
+internal form. The pattern is a C string terminated by a binary zero, and
+is passed in the argument \fIpattern\fP. The \fIpreg\fP argument is a pointer
+to a \fBregex_t\fP structure that is used as a base for storing information
+about the compiled regular expression.
+.P
+The argument \fIcflags\fP is either zero, or contains one or more of the bits
+defined by the following macros:
+.sp
+ REG_DOTALL
+.sp
+The PCRE2_DOTALL option is set when the regular expression is passed for
+compilation to the native function. Note that REG_DOTALL is not part of the
+POSIX standard.
+.sp
+ REG_ICASE
+.sp
+The PCRE2_CASELESS option is set when the regular expression is passed for
+compilation to the native function.
+.sp
+ REG_NEWLINE
+.sp
+The PCRE2_MULTILINE option is set when the regular expression is passed for
+compilation to the native function. Note that this does \fInot\fP mimic the
+defined POSIX behaviour for REG_NEWLINE (see the following section).
+.sp
+ REG_NOSUB
+.sp
+The PCRE2_NO_AUTO_CAPTURE option is set when the regular expression is passed
+for compilation to the native function. In addition, when a pattern that is
+compiled with this flag is passed to \fBregexec()\fP for matching, the
+\fInmatch\fP and \fIpmatch\fP arguments are ignored, and no captured strings
+are returned.
+.sp
+ REG_UCP
+.sp
+The PCRE2_UCP option is set when the regular expression is passed for
+compilation to the native function. This causes PCRE2 to use Unicode properties
+when matchine \ed, \ew, etc., instead of just recognizing ASCII values. Note
+that REG_UCP is not part of the POSIX standard.
+.sp
+ REG_UNGREEDY
+.sp
+The PCRE2_UNGREEDY option is set when the regular expression is passed for
+compilation to the native function. Note that REG_UNGREEDY is not part of the
+POSIX standard.
+.sp
+ REG_UTF
+.sp
+The PCRE2_UTF option is set when the regular expression is passed for
+compilation to the native function. This causes the pattern itself and all data
+strings used for matching it to be treated as UTF-8 strings. Note that REG_UTF
+is not part of the POSIX standard.
+.P
+In the absence of these flags, no options are passed to the native function.
+This means the the regex is compiled with PCRE2 default semantics. In
+particular, the way it handles newline characters in the subject string is the
+Perl way, not the POSIX way. Note that setting PCRE2_MULTILINE has only
+\fIsome\fP of the effects specified for REG_NEWLINE. It does not affect the way
+newlines are matched by the dot metacharacter (they are not) or by a negative
+class such as [^a] (they are).
+.P
+The yield of \fBregcomp()\fP is zero on success, and non-zero otherwise. The
+\fIpreg\fP structure is filled in on success, and one member of the structure
+is public: \fIre_nsub\fP contains the number of capturing subpatterns in
+the regular expression. Various error codes are defined in the header file.
+.P
+NOTE: If the yield of \fBregcomp()\fP is non-zero, you must not attempt to
+use the contents of the \fIpreg\fP structure. If, for example, you pass it to
+\fBregexec()\fP, the result is undefined and your program is likely to crash.
+.
+.
+.SH "MATCHING NEWLINE CHARACTERS"
+.rs
+.sp
+This area is not simple, because POSIX and Perl take different views of things.
+It is not possible to get PCRE2 to obey POSIX semantics, but then PCRE2 was
+never intended to be a POSIX engine. The following table lists the different
+possibilities for matching newline characters in Perl and PCRE2:
+.sp
+ Default Change with
+.sp
+ . matches newline no PCRE2_DOTALL
+ newline matches [^a] yes not changeable
+ $ matches \en at end yes PCRE2_DOLLAR_ENDONLY
+ $ matches \en in middle no PCRE2_MULTILINE
+ ^ matches \en in middle no PCRE2_MULTILINE
+.sp
+This is the equivalent table for a POSIX-compatible pattern matcher:
+.sp
+ Default Change with
+.sp
+ . matches newline yes REG_NEWLINE
+ newline matches [^a] yes REG_NEWLINE
+ $ matches \en at end no REG_NEWLINE
+ $ matches \en in middle no REG_NEWLINE
+ ^ matches \en in middle no REG_NEWLINE
+.sp
+This behaviour is not what happens when PCRE2 is called via its POSIX
+API. By default, PCRE2's behaviour is the same as Perl's, except that there is
+no equivalent for PCRE2_DOLLAR_ENDONLY in Perl. In both PCRE2 and Perl, there
+is no way to stop newline from matching [^a].
+.P
+Default POSIX newline handling can be obtained by setting PCRE2_DOTALL and
+PCRE2_DOLLAR_ENDONLY when calling \fBpcre2_compile()\fP directly, but there is
+no way to make PCRE2 behave exactly as for the REG_NEWLINE action. When using
+the POSIX API, passing REG_NEWLINE to PCRE2's \fBregcomp()\fP function
+causes PCRE2_MULTILINE to be passed to \fBpcre2_compile()\fP, and REG_DOTALL
+passes PCRE2_DOTALL. There is no way to pass PCRE2_DOLLAR_ENDONLY.
+.
+.
+.SH "MATCHING A PATTERN"
+.rs
+.sp
+The function \fBregexec()\fP is called to match a compiled pattern \fIpreg\fP
+against a given \fIstring\fP, which is by default terminated by a zero byte
+(but see REG_STARTEND below), subject to the options in \fIeflags\fP. These can
+be:
+.sp
+ REG_NOTBOL
+.sp
+The PCRE2_NOTBOL option is set when calling the underlying PCRE2 matching
+function.
+.sp
+ REG_NOTEMPTY
+.sp
+The PCRE2_NOTEMPTY option is set when calling the underlying PCRE2 matching
+function. Note that REG_NOTEMPTY is not part of the POSIX standard. However,
+setting this option can give more POSIX-like behaviour in some situations.
+.sp
+ REG_NOTEOL
+.sp
+The PCRE2_NOTEOL option is set when calling the underlying PCRE2 matching
+function.
+.sp
+ REG_STARTEND
+.sp
+The string is considered to start at \fIstring\fP + \fIpmatch[0].rm_so\fP and
+to have a terminating NUL located at \fIstring\fP + \fIpmatch[0].rm_eo\fP
+(there need not actually be a NUL at that location), regardless of the value of
+\fInmatch\fP. This is a BSD extension, compatible with but not specified by
+IEEE Standard 1003.2 (POSIX.2), and should be used with caution in software
+intended to be portable to other systems. Note that a non-zero \fIrm_so\fP does
+not imply REG_NOTBOL; REG_STARTEND affects only the location of the string, not
+how it is matched. Setting REG_STARTEND and passing \fIpmatch\fP as NULL are
+mutually exclusive; the error REG_INVARG is returned.
+.P
+If the pattern was compiled with the REG_NOSUB flag, no data about any matched
+strings is returned. The \fInmatch\fP and \fIpmatch\fP arguments of
+\fBregexec()\fP are ignored.
+.P
+If the value of \fInmatch\fP is zero, or if the value \fIpmatch\fP is NULL,
+no data about any matched strings is returned.
+.P
+Otherwise,the portion of the string that was matched, and also any captured
+substrings, are returned via the \fIpmatch\fP argument, which points to an
+array of \fInmatch\fP structures of type \fIregmatch_t\fP, containing the
+members \fIrm_so\fP and \fIrm_eo\fP. These contain the byte offset to the first
+character of each substring and the offset to the first character after the end
+of each substring, respectively. The 0th element of the vector relates to the
+entire portion of \fIstring\fP that was matched; subsequent elements relate to
+the capturing subpatterns of the regular expression. Unused entries in the
+array have both structure members set to -1.
+.P
+A successful match yields a zero return; various error codes are defined in the
+header file, of which REG_NOMATCH is the "expected" failure code.
+.
+.
+.SH "ERROR MESSAGES"
+.rs
+.sp
+The \fBregerror()\fP function maps a non-zero errorcode from either
+\fBregcomp()\fP or \fBregexec()\fP to a printable message. If \fIpreg\fP is not
+NULL, the error should have arisen from the use of that structure. A message
+terminated by a binary zero is placed in \fIerrbuf\fP. If the buffer is too
+short, only the first \fIerrbuf_size\fP - 1 characters of the error message are
+used. The yield of the function is the size of buffer needed to hold the whole
+message, including the terminating zero. This value is greater than
+\fIerrbuf_size\fP if the message was truncated.
+.
+.
+.SH MEMORY USAGE
+.rs
+.sp
+Compiling a regular expression causes memory to be allocated and associated
+with the \fIpreg\fP structure. The function \fBregfree()\fP frees all such
+memory, after which \fIpreg\fP may no longer be used as a compiled expression.

+PCRE2 - Perl-compatible regular expressions (revised API)
+.SH "PCRE2 SAMPLE PROGRAM"
+.rs
+.sp
+A simple, complete demonstration program to get you started with using PCRE2 is
+supplied in the file \fIpcre2demo.c\fP in the \fBsrc\fP directory in the PCRE2
+distribution. A listing of this program is given in the
+.\" HREF
+\fBpcre2demo\fP
+.\"
+documentation. If you do not have a copy of the PCRE2 distribution, you can
+save this listing to re-create the contents of \fIpcre2demo.c\fP.
+.P
+The demonstration program, which uses the PCRE2 8-bit library, compiles the
+regular expression that is its first argument, and matches it against the
+subject string in its second argument. No PCRE2 options are set, and default
+character tables are used. If matching succeeds, the program outputs the
+portion of the subject that matched, together with the contents of any captured
+substrings.
+.P
+If the -g option is given on the command line, the program then goes on to
+check for further matches of the same regular expression in the same subject
+string. The logic is a little bit tricky because of the possibility of matching
+an empty string. Comments in the code explain what is going on.
+.P
+If PCRE2 is installed in the standard include and library directories for your
+operating system, you should be able to compile the demonstration program using
+this command:
+.sp
+ gcc -o pcre2demo pcre2demo.c -lpcre2-8
+.sp
+If PCRE2 is installed elsewhere, you may need to add additional options to the
+command line. For example, on a Unix-like system that has PCRE2 installed in
+\fI/usr/local\fP, you can compile the demonstration program using a command
+like this:
+.sp
+.\" JOINSH
+ gcc -o pcre2demo -I/usr/local/include pcre2demo.c \e
+ -L/usr/local/lib -lpcre2-8
+.sp

+If you are running an application that uses a large number of regular
+expression patterns, it may be useful to store them in a precompiled form
+instead of having to compile them every time the application is run. However,
+if you are using the just-in-time optimization feature, it is not possible to
+save and reload the JIT data, because it is position-dependent. The host on
+which the patterns are reloaded must be running the same version of PCRE2, with
+the same code unit width, and must also have the same endianness, pointer width
+and PCRE2_SIZE type. For example, patterns compiled on a 32-bit system using
+PCRE2's 16-bit library cannot be reloaded on a 64-bit system, nor can they be
+reloaded using the 8-bit library.
+.
+.
+.SH "SAVING COMPILED PATTERNS"
+.rs
+.sp
+Before compiled patterns can be saved they must be serialized, that is,
+converted to a stream of bytes. A single byte stream may contain any number of
+compiled patterns, but they must all use the same character tables. A single
+copy of the tables is included in the byte stream (its size is 1088 bytes). For
+more details of character tables, see the
+.\" HTML <a href="pcre2api.html#localesupport">
+.\" </a>
+section on locale support
+.\"
+in the
+.\" HREF
+\fBpcre2api\fP
+.\"
+documentation.
+.P
+The function \fBpcre2_serialize_encode()\fP creates a serialized byte stream
+from a list of compiled patterns. Its first two arguments specify the list,
+being a pointer to a vector of pointers to compiled patterns, and the length of
+the vector. The third and fourth arguments point to variables which are set to
+point to the created byte stream and its length, respectively. The final
+argument is a pointer to a general context, which can be used to specify custom
+memory mangagement functions. If this argument is NULL, \fBmalloc()\fP is used
+to obtain memory for the byte stream. The yield of the function is the number
+of serialized patterns, or one of the following negative error codes:
+.sp
+ PCRE2_ERROR_BADDATA the number of patterns is zero or less
+ PCRE2_ERROR_BADMAGIC mismatch of id bytes in one of the patterns
+ PCRE2_ERROR_MEMORY memory allocation failed
+ PCRE2_ERROR_MIXEDTABLES the patterns do not all use the same tables
+ PCRE2_ERROR_NULL the 1st, 3rd, or 4th argument is NULL
+.sp
+PCRE2_ERROR_BADMAGIC means either that a pattern's code has been corrupted, or
+that a slot in the vector does not point to a compiled pattern.
+.P
+Once a set of patterns has been serialized you can save the data in any
+appropriate manner. Here is sample code that compiles two patterns and writes
+them to a file. It assumes that the variable \fIfd\fP refers to a file that is
+open for output. The error checking that should be present in a real
+application has been omitted for simplicity.
+.sp
+ int errorcode;
+ uint8_t *bytes;
+ PCRE2_SIZE erroroffset;
+ PCRE2_SIZE bytescount;
+ pcre2_code *list_of_codes[2];
+ list_of_codes[0] = pcre2_compile("first pattern",
+ PCRE2_ZERO_TERMINATED, 0, &errorcode, &erroroffset, NULL);
+ list_of_codes[1] = pcre2_compile("second pattern",
+ PCRE2_ZERO_TERMINATED, 0, &errorcode, &erroroffset, NULL);
+ errorcode = pcre2_serialize_encode(list_of_codes, 2, &bytes,
+ &bytescount, NULL);
+ errorcode = fwrite(bytes, 1, bytescount, fd);
+.sp
+Note that the serialized data is binary data that may contain any of the 256
+possible byte values. On systems that make a distinction between binary and
+non-binary data, be sure that the file is opened for binary output.
+.P
+Serializing a set of patterns leaves the original data untouched, so they can
+still be used for matching. Their memory must eventually be freed in the usual
+way by calling \fBpcre2_code_free()\fP. When you have finished with the byte
+stream, it too must be freed by calling \fBpcre2_serialize_free()\fP.
+.
+.
+.SH "RE-USING PRECOMPILED PATTERNS"
+.rs
+.sp
+In order to re-use a set of saved patterns you must first make the serialized
+byte stream available in main memory (for example, by reading from a file). The
+management of this memory block is up to the application. You can use the
+\fBpcre2_serialize_get_number_of_codes()\fP function to find out how many
+compiled patterns are in the serialized data without actually decoding the
+patterns:
+.sp
+ uint8_t *bytes = <serialized data>;
+ int32_t number_of_codes = pcre2_serialize_get_number_of_codes(bytes);
+.sp
+The \fBpcre2_serialize_decode()\fP function reads a byte stream and recreates
+the compiled patterns in new memory blocks, setting pointers to them in a
+vector. The first two arguments are a pointer to a suitable vector and its
+length, and the third argument points to a byte stream. The final argument is a
+pointer to a general context, which can be used to specify custom memory
+mangagement functions for the decoded patterns. If this argument is NULL,
+\fBmalloc()\fP and \fBfree()\fP are used. After deserialization, the byte
+stream is no longer needed and can be discarded.
+.sp
+ int32_t number_of_codes;
+ pcre2_code *list_of_codes[2];
+ uint8_t *bytes = <serialized data>;
+ int32_t number_of_codes =
+ pcre2_serialize_decode(list_of_codes, 2, bytes, NULL);
+.sp
+If the vector is not large enough for all the patterns in the byte stream, it
+is filled with those that fit, and the remainder are ignored. The yield of the
+function is the number of decoded patterns, or one of the following negative
+error codes:
+.sp
+ PCRE2_ERROR_BADDATA second argument is zero or less
+ PCRE2_ERROR_BADMAGIC mismatch of id bytes in the data
+ PCRE2_ERROR_BADMODE mismatch of variable unit size or PCRE2 version
+ PCRE2_ERROR_MEMORY memory allocation failed
+ PCRE2_ERROR_NULL first or third argument is NULL
+.sp
+PCRE2_ERROR_BADMAGIC may mean that the data is corrupt, or that it was compiled
+on a system with different endianness.
+.P
+Decoded patterns can be used for matching in the usual way, and must be freed
+by calling \fBpcre2_code_free()\fP. However, be aware that there is a potential
+race issue if you are using multiple patterns that were decoded from a single
+byte stream in a multithreaded application. A single copy of the character
+tables is used by all the decoded patterns and a reference count is used to
+arrange for its memory to be automatically freed when the last pattern is
+freed, but there is no locking on this reference count. Therefore, if you want
+to call \fBpcre2_code_free()\fP for these patterns in different threads, you
+must arrange your own locking, and ensure that \fBpcre2_code_free()\fP cannot
+be called by two threads at the same time.
+.P
+If a pattern was processed by \fBpcre2_jit_compile()\fP before being
+serialized, the JIT data is discarded and so is no longer available after a
+save/restore cycle. You can, however, process a restored pattern with
+\fBpcre2_jit_compile()\fP if you wish.

+.TH PCRE2STACK 3 "21 November 2014" "PCRE2 10.00"
+.SH NAME
+PCRE2 - Perl-compatible regular expressions (revised API)
+.SH "PCRE2 DISCUSSION OF STACK USAGE"
+.rs
+.sp
+When you call \fBpcre2_match()\fP, it makes use of an internal function called
+\fBmatch()\fP. This calls itself recursively at branch points in the pattern,
+in order to remember the state of the match so that it can back up and try a
+different alternative after a failure. As matching proceeds deeper and deeper
+into the tree of possibilities, the recursion depth increases. The
+\fBmatch()\fP function is also called in other circumstances, for example,
+whenever a parenthesized sub-pattern is entered, and in certain cases of
+repetition.
+.P
+Not all calls of \fBmatch()\fP increase the recursion depth; for an item such
+as a* it may be called several times at the same level, after matching
+different numbers of a's. Furthermore, in a number of cases where the result of
+the recursive call would immediately be passed back as the result of the
+current call (a "tail recursion"), the function is just restarted instead.
+.P
+Each time the internal \fBmatch()\fP function is called recursively, it uses
+memory from the process stack. For certain kinds of pattern and data, very
+large amounts of stack may be needed, despite the recognition of "tail
+recursion". Note that if PCRE2 is compiled with the -fsanitize=address option
+of the GCC compiler, the stack requirements are greatly increased.
+.P
+The above comments apply when \fBpcre2_match()\fP is run in its normal
+interpretive manner. If the compiled pattern was processed by
+\fBpcre2_jit_compile()\fP, and just-in-time compiling was successful, and the
+options passed to \fBpcre2_match()\fP were not incompatible, the matching
+process uses the JIT-compiled code instead of the \fBmatch()\fP function. In
+this case, the memory requirements are handled entirely differently. See the
+.\" HREF
+\fBpcre2jit\fP
+.\"
+documentation for details.
+.P
+The \fBpcre2_dfa_match()\fP function operates in a different way to
+\fBpcre2_match()\fP, and uses recursion only when there is a regular expression
+recursion or subroutine call in the pattern. This includes the processing of
+assertion and "once-only" subpatterns, which are handled like subroutine calls.
+Normally, these are never very deep, and the limit on the complexity of
+\fBpcre2_dfa_match()\fP is controlled by the amount of workspace it is given.
+However, it is possible to write patterns with runaway infinite recursions;
+such patterns will cause \fBpcre2_dfa_match()\fP to run out of stack. At
+present, there is no protection against this.
+.P
+The comments that follow do NOT apply to \fBpcre2_dfa_match()\fP; they are
+relevant only for \fBpcre2_match()\fP without the JIT optimization.
+.
+.
+.SS "Reducing \fBpcre2_match()\fP's stack usage"
+.rs
+.sp
+You can often reduce the amount of recursion, and therefore the
+amount of stack used, by modifying the pattern that is being matched. Consider,
+for example, this pattern:
+.sp
+ ([^<]|<(?!inet))+
+.sp
+It matches from wherever it starts until it encounters "<inet" or the end of
+the data, and is the kind of pattern that might be used when processing an XML
+file. Each iteration of the outer parentheses matches either one character that
+is not "<" or a "<" that is not followed by "inet". However, each time a
+parenthesis is processed, a recursion occurs, so this formulation uses a stack
+frame for each matched character. For a long string, a lot of stack is
+required. Consider now this rewritten pattern, which matches exactly the same
+strings:
+.sp
+ ([^<]++|<(?!inet))+
+.sp
+This uses very much less stack, because runs of characters that do not contain
+"<" are "swallowed" in one item inside the parentheses. Recursion happens only
+when a "<" character that is not followed by "inet" is encountered (and we
+assume this is relatively rare). A possessive quantifier is used to stop any
+backtracking into the runs of non-"<" characters, but that is not related to
+stack usage.
+.P
+This example shows that one way of avoiding stack problems when matching long
+subject strings is to write repeated parenthesized subpatterns to match more
+than one character whenever possible.
+.
+.
+.SS "Compiling PCRE2 to use heap instead of stack for \fBpcre2_match()\fP"
+.rs
+.sp
+In environments where stack memory is constrained, you might want to compile
+PCRE2 to use heap memory instead of stack for remembering back-up points when
+\fBpcre2_match()\fP is running. This makes it run more slowly, however. Details
+of how to do this are given in the
+.\" HREF
+\fBpcre2build\fP
+.\"
+documentation. When built in this way, instead of using the stack, PCRE2
+gets memory for remembering backup points from the heap. By default, the memory
+is obtained by calling the system \fBmalloc()\fP function, but you can arrange
+to supply your own memory management function. For details, see the section
+entitled
+.\" HTML <a href="pcre2api.html#matchcontext">
+.\" </a>
+"The match context"
+.\"
+in the
+.\" HREF
+\fBpcre2api\fP
+.\"
+documentation. Since the block sizes are always the same, it may be possible to
+implement customized a memory handler that is more efficient than the standard
+function. The memory blocks obtained for this purpose are retained and re-used
+if possible while \fBpcre2_match()\fP is running. They are all freed just
+before it exits.
+.
+.
+.SS "Limiting \fBpcre2_match()\fP's stack usage"
+.rs
+.sp
+You can set limits on the number of times the internal \fBmatch()\fP function
+is called, both in total and recursively. If a limit is exceeded,
+\fBpcre2_match()\fP returns an error code. Setting suitable limits should
+prevent it from running out of stack. The default values of the limits are very
+large, and unlikely ever to operate. They can be changed when PCRE2 is built,
+and they can also be set when \fBpcre2_match()\fP is called. For details of
+these interfaces, see the
+.\" HREF
+\fBpcre2build\fP
+.\"
+documentation and the section entitled
+.\" HTML <a href="pcre2api.html#matchcontext">
+.\" </a>
+"The match context"
+.\"
+in the
+.\" HREF
+\fBpcre2api\fP
+.\"
+documentation.
+.P
+As a very rough rule of thumb, you should reckon on about 500 bytes per
+recursion. Thus, if you want to limit your stack usage to 8Mb, you should set
+the limit at 16000 recursions. A 64Mb stack, on the other hand, can support
+around 128000 recursions.
+.P
+The \fBpcre2test\fP test program has a modifier called "find_limits" which, if
+applied to a subject line, causes it to find the smallest limits that allow a a
+pattern to match. This is done by calling \fBpcre2_match()\fP repeatedly with
+different limits.
+.
+.
+.SS "Changing stack size in Unix-like systems"
+.rs
+.sp
+In Unix-like environments, there is not often a problem with the stack unless
+very long strings are involved, though the default limit on stack size varies
+from system to system. Values from 8Mb to 64Mb are common. You can find your
+default limit by running the command:
+.sp
+ ulimit -s
+.sp
+Unfortunately, the effect of running out of stack is often SIGSEGV, though
+sometimes a more explicit error message is given. You can normally increase the
+limit on stack size by code such as this:
+.sp
+ struct rlimit rlim;
+ getrlimit(RLIMIT_STACK, &rlim);
+ rlim.rlim_cur = 100*1024*1024;
+ setrlimit(RLIMIT_STACK, &rlim);
+.sp
+This reads the current limits (soft and hard) using \fBgetrlimit()\fP, then
+attempts to increase the soft limit to 100Mb using \fBsetrlimit()\fP. You must
+do this before calling \fBpcre2_match()\fP.
+.
+.
+.SS "Changing stack size in Mac OS X"
+.rs
+.sp
+Using \fBsetrlimit()\fP, as described above, should also work on Mac OS X. It
+is also possible to set a stack size when linking a program. There is a
+discussion about stack sizes in Mac OS X at this web site:
+.\" HTML <a href="http://developer.apple.com/qa/qa2005/qa1419.html">

+ \exhh character with hex code hh
+ \ex{hhh..} character with hex code hhh..
+.sp
+Note that \e0dd is always an octal code. The treatment of backslash followed by
+a non-zero digit is complicated; for details see the section

+"Non-printing characters"
+.\"
+in the
+.\" HREF

+.\"
+documentation, where details of escape processing in EBCDIC environments are
+also given.
+.P
+When \ex is not followed by {, from zero to two hexadecimal digits are read,
+but if PCRE2_ALT_BSUX is set, \ex must be followed by two hexadecimal digits to
+be recognized as a hexadecimal escape; otherwise it matches a literal "x".
+Likewise, if \eu (in ALT_BSUX mode) is not followed by four hexadecimal digits,
+it matches a literal "u".
+.
+.
+.SH "CHARACTER TYPES"
+.rs
+.sp
+ . any character except newline;
+ in dotall mode, any character whatsoever
+ \eC one code unit, even in UTF mode (best avoided)
+ \ed a decimal digit
+ \eD a character that is not a decimal digit

+ \eV a character that is not a vertical white space character
+ \ew a "word" character
+ \eW a "non-word" character
+ \eX a Unicode extended grapheme cluster
+.sp
+\eC is dangerous because it may leave the current matching point in the middle
+of a UTF-8 or UTF-16 character. The application can lock out the use of \eC by
+setting the PCRE2_NEVER_BACKSLASH_C option. It is also possible to build PCRE2
+with the use of \eC permanently disabled.
+.P
+By default, \ed, \es, and \ew match only ASCII characters, even in UTF-8 mode
+or in the 16-bit and 32-bit libraries. However, if locale-specific matching is
+happening, \es and \ew may also match characters with code points in the range
+128-255. If the PCRE2_UCP option is set, the behaviour of these escape
+sequences is changed to use Unicode properties and they match many more
+characters.

+.TH PCRE2TEST 1 "12 December 2015" "PCRE 10.21"
+.SH NAME
+pcre2test - a program for testing Perl-compatible regular expressions.
+.SH SYNOPSIS
+.rs
+.sp
+.B pcre2test "[options] [input file [output file]]"
+.sp
+\fBpcre2test\fP is a test program for the PCRE2 regular expression libraries,
+but it can also be used for experimenting with regular expressions. This
+document describes the features of the test program; for details of the regular
+expressions themselves, see the
+.\" HREF
+\fBpcre2pattern\fP
+.\"
+documentation. For details of the PCRE2 library function calls and their
+options, see the
+.\" HREF
+\fBpcre2api\fP
+.\"
+documentation.
+.P
+The input for \fBpcre2test\fP is a sequence of regular expression patterns and
+subject strings to be matched. There are also command lines for setting
+defaults and controlling some special actions. The output shows the result of
+each match attempt. Modifiers on external or internal command lines, the
+patterns, and the subject lines specify PCRE2 function options, control how the
+subject is processed, and what output is produced.
+.P
+As the original fairly simple PCRE library evolved, it acquired many different
+features, and as a result, the original \fBpcretest\fP program ended up with a
+lot of options in a messy, arcane syntax, for testing all the features. The
+move to the new PCRE2 API provided an opportunity to re-implement the test
+program as \fBpcre2test\fP, with a cleaner modifier syntax. Nevertheless, there
+are still many obscure modifiers, some of which are specifically designed for
+use in conjunction with the test script and data files that are distributed as
+part of PCRE2. All the modifiers are documented here, some without much
+justification, but many of them are unlikely to be of use except when testing
+the libraries.
+.
+.
+.SH "PCRE2's 8-BIT, 16-BIT AND 32-BIT LIBRARIES"
+.rs
+.sp
+Different versions of the PCRE2 library can be built to support character
+strings that are encoded in 8-bit, 16-bit, or 32-bit code units. One, two, or
+all three of these libraries may be simultaneously installed. The
+\fBpcre2test\fP program can be used to test all the libraries. However, its own
+input and output are always in 8-bit format. When testing the 16-bit or 32-bit
+libraries, patterns and subject strings are converted to 16- or 32-bit format
+before being passed to the library functions. Results are converted back to
+8-bit code units for output.
+.P
+In the rest of this document, the names of library functions and structures
+are given in generic form, for example, \fBpcre_compile()\fP. The actual
+names used in the libraries have a suffix _8, _16, or _32, as appropriate.
+.
+.
+.SH "INPUT ENCODING"
+.rs
+.sp
+Input to \fBpcre2test\fP is processed line by line, either by calling the C
+library's \fBfgets()\fP function, or via the \fBlibreadline\fP library (see
+below). The input is processed using using C's string functions, so must not
+contain binary zeroes, even though in Unix-like environments, \fBfgets()\fP
+treats any bytes other than newline as data characters. In some Windows
+environments character 26 (hex 1A) causes an immediate end of file, and no
+further data is read.
+.P
+For maximum portability, therefore, it is safest to avoid non-printing
+characters in \fBpcre2test\fP input files. There is a facility for specifying a
+pattern's characters as hexadecimal pairs, thus making it possible to include
+binary zeroes in a pattern for testing purposes. Subject lines are processed
+for backslash escapes, which makes it possible to include any data value.
+.
+.
+.SH "COMMAND LINE OPTIONS"
+.rs
+.TP 10
+\fB-8\fP
+If the 8-bit library has been built, this option causes it to be used (this is
+the default). If the 8-bit library has not been built, this option causes an
+error.
+.TP 10
+\fB-16\fP
+If the 16-bit library has been built, this option causes it to be used. If only
+the 16-bit library has been built, this is the default. If the 16-bit library
+has not been built, this option causes an error.
+.TP 10
+\fB-32\fP
+If the 32-bit library has been built, this option causes it to be used. If only
+the 32-bit library has been built, this is the default. If the 32-bit library
+has not been built, this option causes an error.
+.TP 10
+\fB-b\fP
+Behave as if each pattern has the \fB/fullbincode\fP modifier; the full
+internal binary form of the pattern is output after compilation.
+.TP 10
+\fB-C\fP
+Output the version number of the PCRE2 library, and all available information
+about the optional features that are included, and then exit with zero exit
+code. All other options are ignored.
+.TP 10
+\fB-C\fP \fIoption\fP
+Output information about a specific build-time option, then exit. This
+functionality is intended for use in scripts such as \fBRunTest\fP. The
+following options output the value and set the exit code as indicated:
+.sp
+ ebcdic-nl the code for LF (= NL) in an EBCDIC environment:
+ 0x15 or 0x25
+ 0 if used in an ASCII environment
+ exit code is always 0
+ linksize the configured internal link size (2, 3, or 4)
+ exit code is set to the link size
+ newline the default newline setting:
+ CR, LF, CRLF, ANYCRLF, or ANY
+ exit code is always 0
+ bsr the default setting for what \eR matches:
+ ANYCRLF or ANY
+ exit code is always 0
+.sp
+The following options output 1 for true or 0 for false, and set the exit code
+to the same value:
+.sp
+ backslash-C \eC is supported (not locked out)
+ ebcdic compiled for an EBCDIC environment
+ jit just-in-time support is available
+ pcre2-16 the 16-bit library was built
+ pcre2-32 the 32-bit library was built
+ pcre2-8 the 8-bit library was built
+ unicode Unicode support is available
+.sp
+If an unknown option is given, an error message is output; the exit code is 0.
+.TP 10
+\fB-d\fP
+Behave as if each pattern has the \fBdebug\fP modifier; the internal
+form and information about the compiled pattern is output after compilation;
+\fB-d\fP is equivalent to \fB-b -i\fP.
+.TP 10
+\fB-dfa\fP
+Behave as if each subject line has the \fBdfa\fP modifier; matching is done
+using the \fBpcre2_dfa_match()\fP function instead of the default
+\fBpcre2_match()\fP.
+.TP 10
+\fB-help\fP
+Output a brief summary these options and then exit.
+.TP 10
+\fB-i\fP
+Behave as if each pattern has the \fB/info\fP modifier; information about the
+compiled pattern is given after compilation.
+.TP 10
+\fB-jit\fP
+Behave as if each pattern line has the \fBjit\fP modifier; after successful
+compilation, each pattern is passed to the just-in-time compiler, if available.
+.TP 10
+\fB-pattern\fB \fImodifier-list\fP
+Behave as if each pattern line contains the given modifiers.
+.TP 10
+\fB-q\fP
+Do not output the version number of \fBpcre2test\fP at the start of execution.
+.TP 10
+\fB-S\fP \fIsize\fP
+On Unix-like systems, set the size of the run-time stack to \fIsize\fP
+megabytes.
+.TP 10
+\fB-subject\fP \fImodifier-list\fP
+Behave as if each subject line contains the given modifiers.
+.TP 10
+\fB-t\fP
+Run each compile and match many times with a timer, and output the resulting
+times per compile or match. When JIT is used, separate times are given for the
+initial compile and the JIT compile. You can control the number of iterations
+that are used for timing by following \fB-t\fP with a number (as a separate
+item on the command line). For example, "-t 1000" iterates 1000 times. The
+default is to iterate 500,000 times.
+.TP 10
+\fB-tm\fP
+This is like \fB-t\fP except that it times only the matching phase, not the
+compile phase.
+.TP 10
+\fB-T\fP \fB-TM\fP
+These behave like \fB-t\fP and \fB-tm\fP, but in addition, at the end of a run,
+the total times for all compiles and matches are output.
+.TP 10
+\fB-version\fP
+Output the PCRE2 version number and then exit.
+.
+.
+.SH "DESCRIPTION"
+.rs
+.sp
+If \fBpcre2test\fP is given two filename arguments, it reads from the first and
+writes to the second. If the first name is "-", input is taken from the
+standard input. If \fBpcre2test\fP is given only one argument, it reads from
+that file and writes to stdout. Otherwise, it reads from stdin and writes to
+stdout.
+.P
+When \fBpcre2test\fP is built, a configuration option can specify that it
+should be linked with the \fBlibreadline\fP or \fBlibedit\fP library. When this
+is done, if the input is from a terminal, it is read using the \fBreadline()\fP
+function. This provides line-editing and history facilities. The output from
+the \fB-help\fP option states whether or not \fBreadline()\fP will be used.
+.P
+The program handles any number of tests, each of which consists of a set of
+input lines. Each set starts with a regular expression pattern, followed by any
+number of subject lines to be matched against that pattern. In between sets of
+test data, command lines that begin with # may appear. This file format, with
+some restrictions, can also be processed by the \fBperltest.sh\fP script that
+is distributed with PCRE2 as a means of checking that the behaviour of PCRE2
+and Perl is the same.
+.P
+When the input is a terminal, \fBpcre2test\fP prompts for each line of input,
+using "re>" to prompt for regular expression patterns, and "data>" to prompt
+for subject lines. Command lines starting with # can be entered only in
+response to the "re>" prompt.
+.P
+Each subject line is matched separately and independently. If you want to do
+multi-line matches, you have to use the \en escape sequence (or \er or \er\en,
+etc., depending on the newline setting) in a single line of input to encode the
+newline sequences. There is no limit on the length of subject lines; the input
+buffer is automatically extended if it is too small. There are replication
+features that makes it possible to generate long repetitive pattern or subject
+lines without having to supply them explicitly.
+.P
+An empty line or the end of the file signals the end of the subject lines for a
+test, at which point a new pattern or command line is expected if there is
+still input to be read.
+.
+.
+.SH "COMMAND LINES"
+.rs
+.sp
+In between sets of test data, a line that begins with # is interpreted as a
+command line. If the first character is followed by white space or an
+exclamation mark, the line is treated as a comment, and ignored. Otherwise, the
+following commands are recognized:
+.sp
+ #forbid_utf
+.sp
+Subsequent patterns automatically have the PCRE2_NEVER_UTF and PCRE2_NEVER_UCP
+options set, which locks out the use of the PCRE2_UTF and PCRE2_UCP options and
+the use of (*UTF) and (*UCP) at the start of patterns. This command also forces
+an error if a subsequent pattern contains any occurrences of \eP, \ep, or \eX,
+which are still supported when PCRE2_UTF is not set, but which require Unicode
+property support to be included in the library.
+.P
+This is a trigger guard that is used in test files to ensure that UTF or
+Unicode property tests are not accidentally added to files that are used when
+Unicode support is not included in the library. Setting PCRE2_NEVER_UTF and
+PCRE2_NEVER_UCP as a default can also be obtained by the use of \fB#pattern\fP;
+the difference is that \fB#forbid_utf\fP cannot be unset, and the automatic
+options are not displayed in pattern information, to avoid cluttering up test
+output.
+.sp
+ #load <filename>
+.sp
+This command is used to load a set of precompiled patterns from a file, as
+described in the section entitled "Saving and restoring compiled patterns"
+.\" HTML <a href="#saverestore">
+.\" </a>
+below.
+.\"
+.sp
+ #newline_default [<newline-list>]
+.sp
+When PCRE2 is built, a default newline convention can be specified. This
+determines which characters and/or character pairs are recognized as indicating
+a newline in a pattern or subject string. The default can be overridden when a
+pattern is compiled. The standard test files contain tests of various newline
+conventions, but the majority of the tests expect a single linefeed to be
+recognized as a newline by default. Without special action the tests would fail
+when PCRE2 is compiled with either CR or CRLF as the default newline.
+.P
+The #newline_default command specifies a list of newline types that are
+acceptable as the default. The types must be one of CR, LF, CRLF, ANYCRLF, or
+ANY (in upper or lower case), for example:
+.sp
+ #newline_default LF Any anyCRLF
+.sp
+If the default newline is in the list, this command has no effect. Otherwise,
+except when testing the POSIX API, a \fBnewline\fP modifier that specifies the
+first newline convention in the list (LF in the above example) is added to any
+pattern that does not already have a \fBnewline\fP modifier. If the newline
+list is empty, the feature is turned off. This command is present in a number
+of the standard test input files.
+.P
+When the POSIX API is being tested there is no way to override the default
+newline convention, though it is possible to set the newline convention from
+within the pattern. A warning is given if the \fBposix\fP modifier is used when
+\fB#newline_default\fP would set a default for the non-POSIX API.
+.sp
+ #pattern <modifier-list>
+.sp
+This command sets a default modifier list that applies to all subsequent
+patterns. Modifiers on a pattern can change these settings.
+.sp
+ #perltest
+.sp
+The appearance of this line causes all subsequent modifier settings to be
+checked for compatibility with the \fBperltest.sh\fP script, which is used to
+confirm that Perl gives the same results as PCRE2. Also, apart from comment
+lines, none of the other command lines are permitted, because they and many
+of the modifiers are specific to \fBpcre2test\fP, and should not be used in
+test files that are also processed by \fBperltest.sh\fP. The \fB#perltest\fP
+command helps detect tests that are accidentally put in the wrong file.
+.sp
+ #pop [<modifiers>]
+.sp
+This command is used to manipulate the stack of compiled patterns, as described
+in the section entitled "Saving and restoring compiled patterns"
+.\" HTML <a href="#saverestore">
+.\" </a>
+below.
+.\"
+.sp
+ #save <filename>
+.sp
+This command is used to save a set of compiled patterns to a file, as described
+in the section entitled "Saving and restoring compiled patterns"
+.\" HTML <a href="#saverestore">
+.\" </a>
+below.
+.\"
+.sp
+ #subject <modifier-list>
+.sp
+This command sets a default modifier list that applies to all subsequent
+subject lines. Modifiers on a subject line can change these settings.
+.
+.
+.SH "MODIFIER SYNTAX"
+.rs
+.sp
+Modifier lists are used with both pattern and subject lines. Items in a list
+are separated by commas followed by optional white space. Trailing whitespace
+in a modifier list is ignored. Some modifiers may be given for both patterns
+and subject lines, whereas others are valid only for one or the other. Each
+modifier has a long name, for example "anchored", and some of them must be
+followed by an equals sign and a value, for example, "offset=12". Values cannot
+contain comma characters, but may contain spaces. Modifiers that do not take
+values may be preceded by a minus sign to turn off a previous setting.
+.P
+A few of the more common modifiers can also be specified as single letters, for
+example "i" for "caseless". In documentation, following the Perl convention,
+these are written with a slash ("the /i modifier") for clarity. Abbreviated
+modifiers must all be concatenated in the first item of a modifier list. If the
+first item is not recognized as a long modifier name, it is interpreted as a
+sequence of these abbreviations. For example:
+.sp
+ /abc/ig,newline=cr,jit=3
+.sp
+This is a pattern line whose modifier list starts with two one-letter modifiers
+(/i and /g). The lower-case abbreviated modifiers are the same as used in Perl.
+.
+.
+.SH "PATTERN SYNTAX"
+.rs
+.sp
+A pattern line must start with one of the following characters (common symbols,
+excluding pattern meta-characters):
+.sp
+ / ! " ' ` - = _ : ; , % & @ ~
+.sp
+This is interpreted as the pattern's delimiter. A regular expression may be
+continued over several input lines, in which case the newline characters are
+included within it. It is possible to include the delimiter within the pattern
+by escaping it with a backslash, for example
+.sp
+ /abc\e/def/
+.sp
+If you do this, the escape and the delimiter form part of the pattern, but
+since the delimiters are all non-alphanumeric, this does not affect its
+interpretation. If the terminating delimiter is immediately followed by a
+backslash, for example,
+.sp
+ /abc/\e
+.sp
+then a backslash is added to the end of the pattern. This is done to provide a
+way of testing the error condition that arises if a pattern finishes with a
+backslash, because
+.sp
+ /abc\e/
+.sp
+is interpreted as the first line of a pattern that starts with "abc/", causing
+pcre2test to read the next line as a continuation of the regular expression.
+.P
+A pattern can be followed by a modifier list (details below).
+.
+.
+.SH "SUBJECT LINE SYNTAX"
+.rs
+.sp
+Before each subject line is passed to \fBpcre2_match()\fP or
+\fBpcre2_dfa_match()\fP, leading and trailing white space is removed, and the
+line is scanned for backslash escapes. The following provide a means of
+encoding non-printing characters in a visible way:
+.sp
+ \ea alarm (BEL, \ex07)
+ \eb backspace (\ex08)
+ \ee escape (\ex27)
+ \ef form feed (\ex0c)
+ \en newline (\ex0a)
+ \er carriage return (\ex0d)
+ \et tab (\ex09)
+ \ev vertical tab (\ex0b)
+ \ennn octal character (up to 3 octal digits); always
+ a byte unless > 255 in UTF-8 or 16-bit or 32-bit mode
+ \eo{dd...} octal character (any number of octal digits}
+ \exhh hexadecimal byte (up to 2 hex digits)
+ \ex{hh...} hexadecimal character (any number of hex digits)
+.sp
+The use of \ex{hh...} is not dependent on the use of the \fButf\fP modifier on
+the pattern. It is recognized always. There may be any number of hexadecimal
+digits inside the braces; invalid values provoke error messages.
+.P
+Note that \exhh specifies one byte rather than one character in UTF-8 mode;
+this makes it possible to construct invalid UTF-8 sequences for testing
+purposes. On the other hand, \ex{hh} is interpreted as a UTF-8 character in
+UTF-8 mode, generating more than one byte if the value is greater than 127.
+When testing the 8-bit library not in UTF-8 mode, \ex{hh} generates one byte
+for values less than 256, and causes an error for greater values.
+.P
+In UTF-16 mode, all 4-digit \ex{hhhh} values are accepted. This makes it
+possible to construct invalid UTF-16 sequences for testing purposes.
+.P
+In UTF-32 mode, all 4- to 8-digit \ex{...} values are accepted. This makes it
+possible to construct invalid UTF-32 sequences for testing purposes.
+.P
+There is a special backslash sequence that specifies replication of one or more
+characters:
+.sp
+ \e[<characters>]{<count>}
+.sp
+This makes it possible to test long strings without having to provide them as
+part of the file. For example:
+.sp
+ \e[abc]{4}
+.sp
+is converted to "abcabcabcabc". This feature does not support nesting. To
+include a closing square bracket in the characters, code it as \ex5D.
+.P
+A backslash followed by an equals sign marks the end of the subject string and
+the start of a modifier list. For example:
+.sp
+ abc\e=notbol,notempty
+.sp
+If the subject string is empty and \e= is followed by whitespace, the line is
+treated as a comment line, and is not used for matching. For example:
+.sp
+ \e= This is a comment.
+ abc\e= This is an invalid modifier list.
+.sp
+A backslash followed by any other non-alphanumeric character just escapes that
+character. A backslash followed by anything else causes an error. However, if
+the very last character in the line is a backslash (and there is no modifier
+list), it is ignored. This gives a way of passing an empty line as data, since
+a real empty line terminates the data input.
+.
+.
+.SH "PATTERN MODIFIERS"
+.rs
+.sp
+There are several types of modifier that can appear in pattern lines. Except
+where noted below, they may also be used in \fB#pattern\fP commands. A
+pattern's modifier list can add to or override default modifiers that were set
+by a previous \fB#pattern\fP command.
+.
+.
+.\" HTML <a name="optionmodifiers"></a>

+.sp
+As well as turning on the PCRE2_UTF option, the \fButf\fP modifier causes all
+non-printing characters in output strings to be printed using the \ex{hh...}
+notation. Otherwise, those less than 0x100 are output in hex without the curly
+brackets.
+.
+.
+.\" HTML <a name="controlmodifiers"></a>
+.SS "Setting compilation controls"
+.rs
+.sp
+The following modifiers affect the compilation process or request information
+about the pattern:
+.sp
+ bsr=[anycrlf|unicode] specify \eR handling
+ /B bincode show binary code without lengths
+ callout_info show callout information
+ debug same as info,fullbincode
+ fullbincode show binary code with lengths
+ /I info show info about compiled pattern

+ parens_nest_limit=<n> set maximum parentheses depth
+ posix use the POSIX API
+ push push compiled pattern onto the stack
+ stackguard=<number> test the stackguard feature
+ tables=[0|1|2] select internal tables
+.sp
+The effects of these modifiers are described in the following sections.
+.
+.
+.SS "Newline and \eR handling"
+.rs
+.sp
+The \fBbsr\fP modifier specifies what \eR in a pattern should match. If it is
+set to "anycrlf", \eR matches CR, LF, or CRLF only. If it is set to "unicode",
+\eR matches any Unicode newline sequence. The default is specified when PCRE2
+is built, with the default default being Unicode.
+.P
+The \fBnewline\fP modifier specifies which characters are to be interpreted as
+newlines, both in the pattern and in subject lines. The type must be one of CR,
+LF, CRLF, ANYCRLF, or ANY (in upper or lower case).
+.
+.
+.SS "Information about a pattern"
+.rs
+.sp
+The \fBdebug\fP modifier is a shorthand for \fBinfo,fullbincode\fP, requesting
+all available information.
+.P
+The \fBbincode\fP modifier causes a representation of the compiled code to be
+output after compilation. This information does not contain length and offset
+values, which ensures that the same output is generated for different internal
+link sizes and different code unit widths. By using \fBbincode\fP, the same
+regression tests can be used in different environments.
+.P
+The \fBfullbincode\fP modifier, by contrast, \fIdoes\fP include length and
+offset values. This is used in a few special tests that run only for specific
+code unit widths and link sizes, and is also useful for one-off tests.
+.P
+The \fBinfo\fP modifier requests information about the compiled pattern
+(whether it is anchored, has a fixed first character, and so on). The
+information is obtained from the \fBpcre2_pattern_info()\fP function. Here are
+some typical examples:
+.sp
+ re> /(?i)(^a|^b)/m,info
+ Capturing subpattern count = 1
+ Compile options: multiline
+ Overall options: caseless multiline
+ First code unit at start or follows newline
+ Subject length lower bound = 1
+.sp
+ re> /(?i)abc/info
+ Capturing subpattern count = 0
+ Compile options: <none>
+ Overall options: caseless
+ First code unit = 'a' (caseless)
+ Last code unit = 'c' (caseless)
+ Subject length lower bound = 3
+.sp
+"Compile options" are those specified by modifiers; "overall options" have
+added options that are taken or deduced from the pattern. If both sets of
+options are the same, just a single "options" line is output; if there are no
+options, the line is omitted. "First code unit" is where any match must start;
+if there is more than one they are listed as "starting code units". "Last code
+unit" is the last literal code unit that must be present in any match. This is
+not necessarily the last character. These lines are omitted if no starting or
+ending code units are recorded.
+.P
+The \fBcallout_info\fP modifier requests information about all the callouts in
+the pattern. A list of them is output at the end of any other information that
+is requested. For each callout, either its number or string is given, followed
+by the item that follows it in the pattern.
+.
+.
+.SS "Passing a NULL context"
+.rs
+.sp
+Normally, \fBpcre2test\fP passes a context block to \fBpcre2_compile()\fP. If
+the \fBnull_context\fP modifier is set, however, NULL is passed. This is for
+testing that \fBpcre2_compile()\fP behaves correctly in this case (it uses
+default values).
+.
+.
+.SS "Specifying a pattern in hex"
+.rs
+.sp
+The \fBhex\fP modifier specifies that the characters of the pattern are to be
+interpreted as pairs of hexadecimal digits. White space is permitted between
+pairs. For example:
+.sp
+ /ab 32 59/hex
+.sp
+This feature is provided as a way of creating patterns that contain binary zero
+and other non-printing characters. By default, \fBpcre2test\fP passes patterns
+as zero-terminated strings to \fBpcre2_compile()\fP, giving the length as
+PCRE2_ZERO_TERMINATED. However, for patterns specified in hexadecimal, the
+actual length of the pattern is passed.
+.
+.
+.SS "Generating long repetitive patterns"
+.rs
+.sp
+Some tests use long patterns that are very repetitive. Instead of creating a
+very long input line for such a pattern, you can use a special repetition
+feature, similar to the one described for subject lines above. If the
+\fBexpand\fP modifier is present on a pattern, parts of the pattern that have
+the form
+.sp
+ \e[<characters>]{<count>}
+.sp
+are expanded before the pattern is passed to \fBpcre2_compile()\fP. For
+example, \e[AB]{6000} is expanded to "ABAB..." 6000 times. This construction
+cannot be nested. An initial "\e[" sequence is recognized only if "]{" followed
+by decimal digits and "}" is found later in the pattern. If not, the characters
+remain in the pattern unaltered.
+.P
+If part of an expanded pattern looks like an expansion, but is really part of
+the actual pattern, unwanted expansion can be avoided by giving two values in
+the quantifier. For example, \e[AB]{6000,6000} is not recognized as an
+expansion item.
+.P
+If the \fBinfo\fP modifier is set on an expanded pattern, the result of the
+expansion is included in the information that is output.
+.
+.
+.SS "JIT compilation"
+.rs
+.sp
+Just-in-time (JIT) compiling is a heavyweight optimization that can greatly
+speed up pattern matching. See the
+.\" HREF
+\fBpcre2jit\fP
+.\"
+documentation for details. JIT compiling happens, optionally, after a pattern
+has been successfully compiled into an internal form. The JIT compiler converts
+this to optimized machine code. It needs to know whether the match-time options
+PCRE2_PARTIAL_HARD and PCRE2_PARTIAL_SOFT are going to be used, because
+different code is generated for the different cases. See the \fBpartial\fP
+modifier in "Subject Modifiers"
+.\" HTML <a href="#subjectmodifiers">
+.\" </a>
+below
+.\"
+for details of how these options are specified for each match attempt.
+.P
+JIT compilation is requested by the \fB/jit\fP pattern modifier, which may
+optionally be followed by an equals sign and a number in the range 0 to 7.
+The three bits that make up the number specify which of the three JIT operating
+modes are to be compiled:
+.sp
+ 1 compile JIT code for non-partial matching
+ 2 compile JIT code for soft partial matching
+ 4 compile JIT code for hard partial matching
+.sp
+The possible values for the \fB/jit\fP modifier are therefore:
+.sp
+ 0 disable JIT
+ 1 normal matching only
+ 2 soft partial matching only
+ 3 normal and soft partial matching
+ 4 hard partial matching only
+ 6 soft and hard partial matching only
+ 7 all three modes
+.sp
+If no number is given, 7 is assumed. The phrase "partial matching" means a call
+to \fBpcre2_match()\fP with either the PCRE2_PARTIAL_SOFT or the
+PCRE2_PARTIAL_HARD option set. Note that such a call may return a complete
+match; the options enable the possibility of a partial match, but do not
+require it. Note also that if you request JIT compilation only for partial
+matching (for example, /jit=2) but do not set the \fBpartial\fP modifier on a
+subject line, that match will not use JIT code because none was compiled for
+non-partial matching.
+.P
+If JIT compilation is successful, the compiled JIT code will automatically be
+used when an appropriate type of match is run, except when incompatible
+run-time options are specified. For more details, see the
+.\" HREF
+\fBpcre2jit\fP
+.\"
+documentation. See also the \fBjitstack\fP modifier below for a way of
+setting the size of the JIT stack.
+.P
+If the \fBjitfast\fP modifier is specified, matching is done using the JIT
+"fast path" interface, \fBpcre2_jit_match()\fP, which skips some of the sanity
+checks that are done by \fBpcre2_match()\fP, and of course does not work when
+JIT is not supported. If \fBjitfast\fP is specified without \fBjit\fP, jit=7 is
+assumed.
+.P
+If the \fBjitverify\fP modifier is specified, information about the compiled
+pattern shows whether JIT compilation was or was not successful. If
+\fBjitverify\fP is specified without \fBjit\fP, jit=7 is assumed. If JIT
+compilation is successful when \fBjitverify\fP is set, the text "(JIT)" is
+added to the first output line after a match or non match when JIT-compiled
+code was actually used in the match.
+.
+.
+.SS "Setting a locale"
+.rs
+.sp
+The \fB/locale\fP modifier must specify the name of a locale, for example:
+.sp
+ /pattern/locale=fr_FR
+.sp
+The given locale is set, \fBpcre2_maketables()\fP is called to build a set of
+character tables for the locale, and this is then passed to
+\fBpcre2_compile()\fP when compiling the regular expression. The same tables
+are used when matching the following subject lines. The \fB/locale\fP modifier
+applies only to the pattern on which it appears, but can be given in a
+\fB#pattern\fP command if a default is needed. Setting a locale and alternate
+character tables are mutually exclusive.
+.
+.
+.SS "Showing pattern memory"
+.rs
+.sp
+The \fB/memory\fP modifier causes the size in bytes of the memory used to hold
+the compiled pattern to be output. This does not include the size of the
+\fBpcre2_code\fP block; it is just the actual compiled data. If the pattern is
+subsequently passed to the JIT compiler, the size of the JIT compiled code is
+also output. Here is an example:
+.sp
+ re> /a(b)c/jit,memory
+ Memory allocation (code space): 21
+ Memory allocation (JIT code): 1910
+.sp
+.
+.
+.SS "Limiting nested parentheses"
+.rs
+.sp
+The \fBparens_nest_limit\fP modifier sets a limit on the depth of nested
+parentheses in a pattern. Breaching the limit causes a compilation error.
+The default for the library is set when PCRE2 is built, but \fBpcre2test\fP
+sets its own default of 220, which is required for running the standard test
+suite.
+.
+.
+.SS "Limiting the pattern length"
+.rs
+.sp
+The \fBmax_pattern_length\fP modifier sets a limit, in code units, to the
+length of pattern that \fBpcre2_compile()\fP will accept. Breaching the limit
+causes a compilation error. The default is the largest number a PCRE2_SIZE
+variable can hold (essentially unlimited).
+.
+.
+.SS "Using the POSIX wrapper API"
+.rs
+.sp
+The \fB/posix\fP modifier causes \fBpcre2test\fP to call PCRE2 via the POSIX
+wrapper API rather than its native API. This supports only the 8-bit library.
+Note that it does not imply POSIX matching semantics; for more detail see the
+.\" HREF
+\fBpcre2posix\fP
+.\"
+documentation. When the POSIX API is being used, the following pattern
+modifiers set options for the \fBregcomp()\fP function:
+.sp
+ caseless REG_ICASE
+ multiline REG_NEWLINE
+ no_auto_capture REG_NOSUB
+ dotall REG_DOTALL )
+ ungreedy REG_UNGREEDY ) These options are not part of
+ ucp REG_UCP ) the POSIX standard
+ utf REG_UTF8 )
+.sp
+The \fBregerror_buffsize\fP modifier specifies a size for the error buffer that
+is passed to \fBregerror()\fP in the event of a compilation error. For example:
+.sp
+ /abc/posix,regerror_buffsize=20
+.sp
+This provides a means of testing the behaviour of \fBregerror()\fP when the
+buffer is too small for the error message. If this modifier has not been set, a
+large buffer is used.
+.P
+The \fBaftertext\fP and \fBallaftertext\fP subject modifiers work as described
+below. All other modifiers cause an error.
+.
+.
+.SS "Testing the stack guard feature"
+.rs
+.sp
+The \fB/stackguard\fP modifier is used to test the use of
+\fBpcre2_set_compile_recursion_guard()\fP, a function that is provided to
+enable stack availability to be checked during compilation (see the
+.\" HREF
+\fBpcre2api\fP
+.\"
+documentation for details). If the number specified by the modifier is greater
+than zero, \fBpcre2_set_compile_recursion_guard()\fP is called to set up
+callback from \fBpcre2_compile()\fP to a local function. The argument it
+receives is the current nesting parenthesis depth; if this is greater than the
+value given by the modifier, non-zero is returned, causing the compilation to
+be aborted.
+.
+.
+.SS "Using alternative character tables"
+.rs
+.sp
+The value specified for the \fB/tables\fP modifier must be one of the digits 0,
+1, or 2. It causes a specific set of built-in character tables to be passed to
+\fBpcre2_compile()\fP. This is used in the PCRE2 tests to check behaviour with
+different character tables. The digit specifies the tables as follows:
+.sp
+ 0 do not pass any special character tables
+ 1 the default ASCII tables, as distributed in
+ pcre2_chartables.c.dist
+ 2 a set of tables defining ISO 8859 characters
+.sp
+In table 2, some characters whose codes are greater than 128 are identified as
+letters, digits, spaces, etc. Setting alternate character tables and a locale
+are mutually exclusive.
+.
+.
+.SS "Setting certain match controls"
+.rs
+.sp
+The following modifiers are really subject modifiers, and are described below.
+However, they may be included in a pattern's modifier list, in which case they
+are applied to every subject line that is processed with that pattern. They may
+not appear in \fB#pattern\fP commands. These modifiers do not affect the
+compilation process.
+.sp
+ aftertext show text after match
+ allaftertext show text after captures
+ allcaptures show all captures
+ allusedtext show all consulted text
+ /g global global matching
+ mark show mark values
+ replace=<string> specify a replacement string
+ startchar show starting character when relevant
+ substitute_extended use PCRE2_SUBSTITUTE_EXTENDED
+ substitute_overflow_length use PCRE2_SUBSTITUTE_OVERFLOW_LENGTH
+ substitute_unknown_unset use PCRE2_SUBSTITUTE_UNKNOWN_UNSET
+ substitute_unset_empty use PCRE2_SUBSTITUTE_UNSET_EMPTY
+.sp
+These modifiers may not appear in a \fB#pattern\fP command. If you want them as
+defaults, set them in a \fB#subject\fP command.
+.
+.
+.SS "Saving a compiled pattern"
+.rs
+.sp
+When a pattern with the \fBpush\fP modifier is successfully compiled, it is
+pushed onto a stack of compiled patterns, and \fBpcre2test\fP expects the next
+line to contain a new pattern (or a command) instead of a subject line. This
+facility is used when saving compiled patterns to a file, as described in the
+section entitled "Saving and restoring compiled patterns"
+.\" HTML <a href="#saverestore">
+.\" </a>
+below.
+.\"
+The \fBpush\fP modifier is incompatible with compilation modifiers such as
+\fBglobal\fP that act at match time. Any that are specified are ignored, with a
+warning message, except for \fBreplace\fP, which causes an error. Note that,
+\fBjitverify\fP, which is allowed, does not carry through to any subsequent
+matching that uses this pattern.
+.
+.

+REG_NOTEMPTY, and REG_NOTEOL, respectively, to be passed to \fBregexec()\fP.

+.
+.SS "Setting match controls"

+ zero_terminate pass the subject as zero-terminated
+.sp
+The effects of these modifiers are described in the following sections.
+.
+.
+.SS "Showing more text"
+.rs
+.sp
+The \fBaftertext\fP modifier requests that as well as outputting the part of
+the subject string that matched the entire pattern, \fBpcre2test\fP should in
+addition output the remainder of the subject string. This is useful for tests
+where the subject contains multiple copies of the same substring. The
+\fBallaftertext\fP modifier requests the same action for captured substrings as
+well as the main matched substring. In each case the remainder is output on the
+following line with a plus character following the capture number.
+.P
+The \fBallusedtext\fP modifier requests that all the text that was consulted
+during a successful pattern match by the interpreter should be shown. This
+feature is not supported for JIT matching, and if requested with JIT it is
+ignored (with a warning message). Setting this modifier affects the output if
+there is a lookbehind at the start of a match, or a lookahead at the end, or if
+\eK is used in the pattern. Characters that precede or follow the start and end
+of the actual match are indicated in the output by '<' or '>' characters
+underneath them. Here is an example:
+.sp
+ re> /(?<=pqr)abc(?=xyz)/
+ data> 123pqrabcxyz456\e=allusedtext
+ 0: pqrabcxyz
+ <<< >>>
+.sp
+This shows that the matched string is "abc", with the preceding and following
+strings "pqr" and "xyz" having been consulted during the match (when processing
+the assertions).
+.P
+The \fBstartchar\fP modifier requests that the starting character for the match
+be indicated, if it is different to the start of the matched string. The only
+time when this occurs is when \eK has been processed as part of the match. In
+this situation, the output for the matched string is displayed from the
+starting character instead of from the match point, with circumflex characters
+under the earlier characters. For example:
+.sp
+ re> /abc\eKxyz/
+ data> abcxyz\e=startchar
+ 0: abcxyz
+ ^^^
+.sp
+Unlike \fBallusedtext\fP, the \fBstartchar\fP modifier can be used with JIT.
+However, these two modifiers are mutually exclusive.
+.
+.
+.SS "Showing the value of all capture groups"
+.rs
+.sp
+The \fBallcaptures\fP modifier requests that the values of all potential
+captured parentheses be output after a match. By default, only those up to the
+highest one actually used in the match are output (corresponding to the return
+code from \fBpcre2_match()\fP). Groups that did not take part in the match
+are output as "<unset>".
+.
+.
+.SS "Testing callouts"
+.rs
+.sp
+A callout function is supplied when \fBpcre2test\fP calls the library matching
+functions, unless \fBcallout_none\fP is specified. If \fBcallout_capture\fP is
+set, the current captured groups are output when a callout occurs.
+.P
+The \fBcallout_fail\fP modifier can be given one or two numbers. If there is
+only one number, 1 is returned instead of 0 when a callout of that number is
+reached. If two numbers are given, 1 is returned when callout <n> is reached
+for the <m>th time. Note that callouts with string arguments are always given
+the number zero. See "Callouts" below for a description of the output when a
+callout it taken.
+.P
+The \fBcallout_data\fP modifier can be given an unsigned or a negative number.
+This is set as the "user data" that is passed to the matching function, and
+passed back when the callout function is invoked. Any value other than zero is
+used as a return from \fBpcre2test\fP's callout function.
+.
+.
+.SS "Finding all matches in a string"
+.rs
+.sp
+Searching for all possible matches within a subject can be requested by the
+\fBglobal\fP or \fB/altglobal\fP modifier. After finding a match, the matching
+function is called again to search the remainder of the subject. The difference
+between \fBglobal\fP and \fBaltglobal\fP is that the former uses the
+\fIstart_offset\fP argument to \fBpcre2_match()\fP or \fBpcre2_dfa_match()\fP
+to start searching at a new point within the entire string (which is what Perl
+does), whereas the latter passes over a shortened subject. This makes a
+difference to the matching process if the pattern begins with a lookbehind
+assertion (including \eb or \eB).
+.P
+If an empty string is matched, the next match is done with the
+PCRE2_NOTEMPTY_ATSTART and PCRE2_ANCHORED flags set, in order to search for
+another, non-empty, match at the same point in the subject. If this match
+fails, the start offset is advanced, and the normal match is retried. This
+imitates the way Perl handles such cases when using the \fB/g\fP modifier or
+the \fBsplit()\fP function. Normally, the start offset is advanced by one
+character, but if the newline convention recognizes CRLF as a newline, and the
+current character is CR followed by LF, an advance of two characters occurs.
+.
+.
+.SS "Testing substring extraction functions"
+.rs
+.sp
+The \fBcopy\fP and \fBget\fP modifiers can be used to test the
+\fBpcre2_substring_copy_xxx()\fP and \fBpcre2_substring_get_xxx()\fP functions.
+They can be given more than once, and each can specify a group name or number,
+for example:
+.sp
+ abcd\e=copy=1,copy=3,get=G1
+.sp
+If the \fB#subject\fP command is used to set default copy and/or get lists,
+these can be unset by specifying a negative number to cancel all numbered
+groups and an empty name to cancel all named groups.
+.P
+The \fBgetall\fP modifier tests \fBpcre2_substring_list_get()\fP, which
+extracts all captured substrings.
+.P
+If the subject line is successfully matched, the substrings extracted by the
+convenience functions are output with C, G, or L after the string number
+instead of a colon. This is in addition to the normal full list. The string
+length (that is, the return from the extraction function) is given in
+parentheses after each substring, followed by the name when the extraction was
+by name.
+.
+.
+.SS "Testing the substitution function"
+.rs
+.sp
+If the \fBreplace\fP modifier is set, the \fBpcre2_substitute()\fP function is
+called instead of one of the matching functions. Note that replacement strings
+cannot contain commas, because a comma signifies the end of a modifier. This is
+not thought to be an issue in a test program.
+.P
+Unlike subject strings, \fBpcre2test\fP does not process replacement strings
+for escape sequences. In UTF mode, a replacement string is checked to see if it
+is a valid UTF-8 string. If so, it is correctly converted to a UTF string of
+the appropriate code unit width. If it is not a valid UTF-8 string, the
+individual code units are copied directly. This provides a means of passing an
+invalid UTF-8 string for testing purposes.
+.P
+The following modifiers set options (in additional to the normal match options)
+for \fBpcre2_substitute()\fP:
+.sp
+ global PCRE2_SUBSTITUTE_GLOBAL
+ substitute_extended PCRE2_SUBSTITUTE_EXTENDED
+ substitute_overflow_length PCRE2_SUBSTITUTE_OVERFLOW_LENGTH
+ substitute_unknown_unset PCRE2_SUBSTITUTE_UNKNOWN_UNSET
+ substitute_unset_empty PCRE2_SUBSTITUTE_UNSET_EMPTY
+.sp
+.P
+After a successful substitution, the modified string is output, preceded by the
+number of replacements. This may be zero if there were no matches. Here is a
+simple example of a substitution test:
+.sp
+ /abc/replace=xxx
+ =abc=abc=
+ 1: =xxx=abc=
+ =abc=abc=\e=global
+ 2: =xxx=xxx=
+.sp
+Subject and replacement strings should be kept relatively short (fewer than 256
+characters) for substitution tests, as fixed-size buffers are used. To make it
+easy to test for buffer overflow, if the replacement string starts with a
+number in square brackets, that number is passed to \fBpcre2_substitute()\fP as
+the size of the output buffer, with the replacement string starting at the next
+character. Here is an example that tests the edge case:
+.sp
+ /abc/
+ 123abc123\e=replace=[10]XYZ
+ 1: 123XYZ123
+ 123abc123\e=replace=[9]XYZ
+ Failed: error -47: no more memory
+.sp
+The default action of \fBpcre2_substitute()\fP is to return
+PCRE2_ERROR_NOMEMORY when the output buffer is too small. However, if the
+PCRE2_SUBSTITUTE_OVERFLOW_LENGTH option is set (by using the
+\fBsubstitute_overflow_length\fP modifier), \fBpcre2_substitute()\fP continues
+to go through the motions of matching and substituting, in order to compute the
+size of buffer that is required. When this happens, \fBpcre2test\fP shows the
+required buffer length (which includes space for the trailing zero) as part of
+the error message. For example:
+.sp
+ /abc/substitute_overflow_length
+ 123abc123\e=replace=[9]XYZ
+ Failed: error -47: no more memory: 10 code units are needed
+.sp
+A replacement string is ignored with POSIX and DFA matching. Specifying partial
+matching provokes an error return ("bad option value") from
+\fBpcre2_substitute()\fP.
+.
+.
+.SS "Setting the JIT stack size"
+.rs
+.sp
+The \fBjitstack\fP modifier provides a way of setting the maximum stack size
+that is used by the just-in-time optimization code. It is ignored if JIT
+optimization is not being used. The value is a number of kilobytes. Providing a
+stack that is larger than the default 32K is necessary only for very
+complicated patterns.
+.
+.
+.SS "Setting match and recursion limits"
+.rs
+.sp
+The \fBmatch_limit\fP and \fBrecursion_limit\fP modifiers set the appropriate
+limits in the match context. These values are ignored when the
+\fBfind_limits\fP modifier is specified.
+.
+.
+.SS "Finding minimum limits"
+.rs
+.sp
+If the \fBfind_limits\fP modifier is present, \fBpcre2test\fP calls
+\fBpcre2_match()\fP several times, setting different values in the match
+context via \fBpcre2_set_match_limit()\fP and \fBpcre2_set_recursion_limit()\fP
+until it finds the minimum values for each parameter that allow
+\fBpcre2_match()\fP to complete without error.
+.P
+If JIT is being used, only the match limit is relevant. If DFA matching is
+being used, neither limit is relevant, and this modifier is ignored (with a
+warning message).
+.P
+The \fImatch_limit\fP number is a measure of the amount of backtracking
+that takes place, and learning the minimum value can be instructive. For most
+simple matches, the number is quite small, but for patterns with very large
+numbers of matching possibilities, it can become large very quickly with
+increasing length of subject string. The \fImatch_limit_recursion\fP number is
+a measure of how much stack (or, if PCRE2 is compiled with NO_RECURSE, how much
+heap) memory is needed to complete the match attempt.
+.
+.
+.SS "Showing MARK names"
+.rs
+.sp
+.P
+The \fBmark\fP modifier causes the names from backtracking control verbs that
+are returned from calls to \fBpcre2_match()\fP to be displayed. If a mark is
+returned for a match, non-match, or partial match, \fBpcre2test\fP shows it.
+For a match, it is on a line by itself, tagged with "MK:". Otherwise, it
+is added to the non-match message.
+.
+.
+.SS "Showing memory usage"
+.rs
+.sp
+The \fBmemory\fP modifier causes \fBpcre2test\fP to log all memory allocation
+and freeing calls that occur during a match operation.
+.
+.
+.SS "Setting a starting offset"
+.rs
+.sp
+The \fBoffset\fP modifier sets an offset in the subject string at which
+matching starts. Its value is a number of code units, not characters.
+.
+.
+.SS "Setting an offset limit"
+.rs
+.sp
+The \fBoffset_limit\fP modifier sets a limit for unanchored matches. If a match
+cannot be found starting at or before this offset in the subject, a "no match"
+return is given. The data value is a number of code units, not characters. When
+this modifier is used, the \fBuse_offset_limit\fP modifier must have been set
+for the pattern; if not, an error is generated.
+.
+.
+.SS "Setting the size of the output vector"
+.rs
+.sp
+The \fBovector\fP modifier applies only to the subject line in which it
+appears, though of course it can also be used to set a default in a
+\fB#subject\fP command. It specifies the number of pairs of offsets that are
+available for storing matching information. The default is 15.
+.P
+A value of zero is useful when testing the POSIX API because it causes
+\fBregexec()\fP to be called with a NULL capture vector. When not testing the
+POSIX API, a value of zero is used to cause
+\fBpcre2_match_data_create_from_pattern()\fP to be called, in order to create a
+match block of exactly the right size for the pattern. (It is not possible to
+create a match block with a zero-length ovector; there is always at least one
+pair of offsets.)
+.
+.
+.SS "Passing the subject as zero-terminated"
+.rs
+.sp
+By default, the subject string is passed to a native API matching function with
+its correct length. In order to test the facility for passing a zero-terminated
+string, the \fBzero_terminate\fP modifier is provided. It causes the length to
+be passed as PCRE2_ZERO_TERMINATED. (When matching via the POSIX interface,
+this modifier has no effect, as there is no facility for passing a length.)
+.P
+When testing \fBpcre2_substitute()\fP, this modifier also has the effect of
+passing the replacement string as zero-terminated.
+.
+.
+.SS "Passing a NULL context"
+.rs
+.sp
+Normally, \fBpcre2test\fP passes a context block to \fBpcre2_match()\fP,
+\fBpcre2_dfa_match()\fP or \fBpcre2_jit_match()\fP. If the \fBnull_context\fP
+modifier is set, however, NULL is passed. This is for testing that the matching
+functions behave correctly in this case (they use default values). This
+modifier cannot be used with the \fBfind_limits\fP modifier or when testing the
+substitution function.
+.
+.
+.SH "THE ALTERNATIVE MATCHING FUNCTION"
+.rs
+.sp
+By default, \fBpcre2test\fP uses the standard PCRE2 matching function,
+\fBpcre2_match()\fP to match each subject line. PCRE2 also supports an
+alternative matching function, \fBpcre2_dfa_match()\fP, which operates in a
+different way, and has some restrictions. The differences between the two
+functions are described in the
+.\" HREF
+\fBpcre2matching\fP
+.\"
+documentation.
+.P
+If the \fBdfa\fP modifier is set, the alternative matching function is used.
+This function finds all possible matches at a given point in the subject. If,
+however, the \fBdfa_shortest\fP modifier is set, processing stops after the
+first match is found. This is always the shortest possible match.
+.
+.
+.SH "DEFAULT OUTPUT FROM pcre2test"
+.rs
+.sp
+This section describes the output when the normal matching function,
+\fBpcre2_match()\fP, is being used.
+.P
+When a match succeeds, \fBpcre2test\fP outputs the list of captured substrings,
+starting with number 0 for the string that matched the whole pattern.
+Otherwise, it outputs "No match" when the return is PCRE2_ERROR_NOMATCH, or
+"Partial match:" followed by the partially matching substring when the
+return is PCRE2_ERROR_PARTIAL. (Note that this is the
+entire substring that was inspected during the partial match; it may include
+characters before the actual match start if a lookbehind assertion, \eK, \eb,
+or \eB was involved.)
+.P
+For any other return, \fBpcre2test\fP outputs the PCRE2 negative error number
+and a short descriptive phrase. If the error is a failed UTF string check, the
+code unit offset of the start of the failing character is also output. Here is
+an example of an interactive \fBpcre2test\fP run.
+.sp
+ $ pcre2test
+ PCRE2 version 9.00 2014-05-10
+.sp
+ re> /^abc(\ed+)/
+ data> abc123
+ 0: abc123
+ 1: 123
+ data> xyz
+ No match
+.sp
+Unset capturing substrings that are not followed by one that is set are not
+shown by \fBpcre2test\fP unless the \fBallcaptures\fP modifier is specified. In
+the following example, there are two capturing substrings, but when the first
+data line is matched, the second, unset substring is not shown. An "internal"
+unset substring is shown as "<unset>", as for the second data line.
+.sp
+ re> /(a)|(b)/
+ data> a
+ 0: a
+ 1: a
+ data> b
+ 0: b
+ 1: <unset>
+ 2: b
+.sp
+If the strings contain any non-printing characters, they are output as \exhh
+escapes if the value is less than 256 and UTF mode is not set. Otherwise they
+are output as \ex{hh...} escapes. See below for the definition of non-printing
+characters. If the \fB/aftertext\fP modifier is set, the output for substring
+0 is followed by the the rest of the subject string, identified by "0+" like
+this:
+.sp
+ re> /cat/aftertext
+ data> cataract
+ 0: cat
+ 0+ aract
+.sp
+If global matching is requested, the results of successive matching attempts
+are output in sequence, like this:
+.sp
+ re> /\eBi(\ew\ew)/g
+ data> Mississippi
+ 0: iss
+ 1: ss
+ 0: iss
+ 1: ss
+ 0: ipp
+ 1: pp
+.sp
+"No match" is output only if the first match attempt fails. Here is an example
+of a failure message (the offset 4 that is specified by the \fBoffset\fP
+modifier is past the end of the subject string):
+.sp
+ re> /xyz/
+ data> xyz\e=offset=4
+ Error -24 (bad offset value)
+.P
+Note that whereas patterns can be continued over several lines (a plain ">"
+prompt is used for continuations), subject lines may not. However newlines can
+be included in a subject by means of the \en escape (or \er, \er\en, etc.,
+depending on the newline sequence setting).
+.
+.
+.
+.SH "OUTPUT FROM THE ALTERNATIVE MATCHING FUNCTION"
+.rs
+.sp
+When the alternative matching function, \fBpcre2_dfa_match()\fP, is used, the
+output consists of a list of all the matches that start at the first point in
+the subject where there is at least one match. For example:
+.sp
+ re> /(tang|tangerine|tan)/
+ data> yellow tangerine\e=dfa
+ 0: tangerine
+ 1: tang
+ 2: tan
+.sp
+Using the normal matching function on this data finds only "tang". The
+longest matching string is always given first (and numbered zero). After a
+PCRE2_ERROR_PARTIAL return, the output is "Partial match:", followed by the
+partially matching substring. Note that this is the entire substring that was
+inspected during the partial match; it may include characters before the actual
+match start if a lookbehind assertion, \eb, or \eB was involved. (\eK is not
+supported for DFA matching.)
+.P
+If global matching is requested, the search for further matches resumes
+at the end of the longest match. For example:
+.sp
+ re> /(tang|tangerine|tan)/g
+ data> yellow tangerine and tangy sultana\e=dfa
+ 0: tangerine
+ 1: tang
+ 2: tan
+ 0: tang
+ 1: tan
+ 0: tan
+.sp
+The alternative matching function does not support substring capture, so the
+modifiers that are concerned with captured substrings are not relevant.
+.
+.
+.SH "RESTARTING AFTER A PARTIAL MATCH"
+.rs
+.sp
+When the alternative matching function has given the PCRE2_ERROR_PARTIAL
+return, indicating that the subject partially matched the pattern, you can
+restart the match with additional subject data by means of the
+\fBdfa_restart\fP modifier. For example:
+.sp
+ re> /^\ed?\ed(jan|feb|mar|apr|may|jun|jul|aug|sep|oct|nov|dec)\ed\ed$/
+ data> 23ja\e=P,dfa
+ Partial match: 23ja
+ data> n05\e=dfa,dfa_restart
+ 0: n05
+.sp
+For further information about partial matching, see the
+.\" HREF
+\fBpcre2partial\fP
+.\"
+documentation.
+.
+.
+.SH CALLOUTS
+.rs
+.sp
+If the pattern contains any callout requests, \fBpcre2test\fP's callout
+function is called during matching unless \fBcallout_none\fP is specified.
+This works with both matching functions.
+.P
+The callout function in \fBpcre2test\fP returns zero (carry on matching) by
+default, but you can use a \fBcallout_fail\fP modifier in a subject line (as
+described above) to change this and other parameters of the callout.
+.P
+Inserting callouts can be helpful when using \fBpcre2test\fP to check
+complicated regular expressions. For further information about callouts, see
+the
+.\" HREF
+\fBpcre2callout\fP
+.\"
+documentation.
+.P
+The output for callouts with numerical arguments and those with string
+arguments is slightly different.
+.
+.
+.SS "Callouts with numerical arguments"
+.rs
+.sp
+By default, the callout function displays the callout number, the start and
+current positions in the subject text at the callout time, and the next pattern
+item to be tested. For example:
+.sp
+ --->pqrabcdef
+ 0 ^ ^ \ed
+.sp
+This output indicates that callout number 0 occurred for a match attempt
+starting at the fourth character of the subject string, when the pointer was at
+the seventh character, and when the next pattern item was \ed. Just
+one circumflex is output if the start and current positions are the same.
+.P
+Callouts numbered 255 are assumed to be automatic callouts, inserted as a
+result of the \fB/auto_callout\fP pattern modifier. In this case, instead of
+showing the callout number, the offset in the pattern, preceded by a plus, is
+output. For example:
+.sp
+ re> /\ed?[A-E]\e*/auto_callout
+ data> E*
+ --->E*
+ +0 ^ \ed?
+ +3 ^ [A-E]
+ +8 ^^ \e*
+ +10 ^ ^
+ 0: E*
+.sp
+If a pattern contains (*MARK) items, an additional line is output whenever
+a change of latest mark is passed to the callout function. For example:
+.sp
+ re> /a(*MARK:X)bc/auto_callout
+ data> abc
+ --->abc
+ +0 ^ a
+ +1 ^^ (*MARK:X)
+ +10 ^^ b
+ Latest Mark: X
+ +11 ^ ^ c
+ +12 ^ ^
+ 0: abc
+.sp
+The mark changes between matching "a" and "b", but stays the same for the rest
+of the match, so nothing more is output. If, as a result of backtracking, the
+mark reverts to being unset, the text "<unset>" is output.
+.
+.
+.SS "Callouts with string arguments"
+.rs
+.sp
+The output for a callout with a string argument is similar, except that instead
+of outputting a callout number before the position indicators, the callout
+string and its offset in the pattern string are output before the reflection of
+the subject string, and the subject string is reflected for each callout. For
+example:
+.sp
+ re> /^ab(?C'first')cd(?C"second")ef/
+ data> abcdefg
+ Callout (7): 'first'
+ --->abcdefg
+ ^ ^ c
+ Callout (20): "second"
+ --->abcdefg
+ ^ ^ e
+ 0: abcdef
+.sp
+.
+.
+.
+.SH "NON-PRINTING CHARACTERS"
+.rs
+.sp
+When \fBpcre2test\fP is outputting text in the compiled version of a pattern,
+bytes other than 32-126 are always treated as non-printing characters and are
+therefore shown as hex escapes.
+.P
+When \fBpcre2test\fP is outputting text that is a matched part of a subject
+string, it behaves in the same way, unless a different locale has been set for
+the pattern (using the \fB/locale\fP modifier). In this case, the
+\fBisprint()\fP function is used to distinguish printing and non-printing
+characters.
+.
+.
+.
+.\" HTML <a name="saverestore"></a>
+.SH "SAVING AND RESTORING COMPILED PATTERNS"
+.rs
+.sp
+It is possible to save compiled patterns on disc or elsewhere, and reload them
+later, subject to a number of restrictions. JIT data cannot be saved. The host
+on which the patterns are reloaded must be running the same version of PCRE2,
+with the same code unit width, and must also have the same endianness, pointer
+width and PCRE2_SIZE type. Before compiled patterns can be saved they must be
+serialized, that is, converted to a stream of bytes. A single byte stream may
+contain any number of compiled patterns, but they must all use the same
+character tables. A single copy of the tables is included in the byte stream
+(its size is 1088 bytes).
+.P
+The functions whose names begin with \fBpcre2_serialize_\fP are used
+for serializing and de-serializing. They are described in the
+.\" HREF
+\fBpcre2serialize\fP
+.\"
+documentation. In this section we describe the features of \fBpcre2test\fP that
+can be used to test these functions.
+.P
+When a pattern with \fBpush\fP modifier is successfully compiled, it is pushed
+onto a stack of compiled patterns, and \fBpcre2test\fP expects the next line to
+contain a new pattern (or command) instead of a subject line. By this means, a
+number of patterns can be compiled and retained. The \fBpush\fP modifier is
+incompatible with \fBposix\fP, and control modifiers that act at match time are
+ignored (with a message). The \fBjitverify\fP modifier applies only at compile
+time. The command
+.sp
+ #save <filename>
+.sp
+causes all the stacked patterns to be serialized and the result written to the
+named file. Afterwards, all the stacked patterns are freed. The command
+.sp
+ #load <filename>
+.sp
+reads the data in the file, and then arranges for it to be de-serialized, with
+the resulting compiled patterns added to the pattern stack. The pattern on the
+top of the stack can be retrieved by the #pop command, which must be followed
+by lines of subjects that are to be matched with the pattern, terminated as
+usual by an empty line or end of file. This command may be followed by a
+modifier list containing only
+.\" HTML <a href="#controlmodifiers">
+.\" </a>
+control modifiers
+.\"
+that act after a pattern has been compiled. In particular, \fBhex\fP,
+\fBposix\fP, and \fBpush\fP are not allowed, nor are any
+.\" HTML <a href="#optionmodifiers">
+.\" </a>
+option-setting modifiers.
+.\"
+The JIT modifiers are, however permitted. Here is an example that saves and
+reloads two patterns.
+.sp
+ /abc/push
+ /xyz/push
+ #save tempfile
+ #load tempfile
+ #pop info
+ xyz
+.sp
+ #pop jit,bincode
+ abc
+.sp
+If \fBjitverify\fP is used with #pop, it does not automatically imply
+\fBjit\fP, which is different behaviour from when it is used on a pattern.

+NAME
+ pcre2test - a program for testing Perl-compatible regular expressions.
+
+SYNOPSIS
+
+ pcre2test [options] [input file [output file]]
+
+ pcre2test is a test program for the PCRE2 regular expression libraries,
+ but it can also be used for experimenting with regular expressions.
+ This document describes the features of the test program; for details
+ of the regular expressions themselves, see the pcre2pattern documenta-
+ tion. For details of the PCRE2 library function calls and their
+ options, see the pcre2api documentation.
+
+ The input for pcre2test is a sequence of regular expression patterns
+ and subject strings to be matched. There are also command lines for
+ setting defaults and controlling some special actions. The output shows
+ the result of each match attempt. Modifiers on external or internal
+ command lines, the patterns, and the subject lines specify PCRE2 func-
+ tion options, control how the subject is processed, and what output is
+ produced.
+
+ As the original fairly simple PCRE library evolved, it acquired many
+ different features, and as a result, the original pcretest program
+ ended up with a lot of options in a messy, arcane syntax, for testing
+ all the features. The move to the new PCRE2 API provided an opportunity
+ to re-implement the test program as pcre2test, with a cleaner modifier
+ syntax. Nevertheless, there are still many obscure modifiers, some of
+ which are specifically designed for use in conjunction with the test
+ script and data files that are distributed as part of PCRE2. All the
+ modifiers are documented here, some without much justification, but
+ many of them are unlikely to be of use except when testing the
+ libraries.
+
+
+PCRE2's 8-BIT, 16-BIT AND 32-BIT LIBRARIES
+
+ Different versions of the PCRE2 library can be built to support charac-
+ ter strings that are encoded in 8-bit, 16-bit, or 32-bit code units.
+ One, two, or all three of these libraries may be simultaneously
+ installed. The pcre2test program can be used to test all the libraries.
+ However, its own input and output are always in 8-bit format. When
+ testing the 16-bit or 32-bit libraries, patterns and subject strings
+ are converted to 16- or 32-bit format before being passed to the
+ library functions. Results are converted back to 8-bit code units for
+ output.
+
+ In the rest of this document, the names of library functions and struc-
+ tures are given in generic form, for example, pcre_compile(). The
+ actual names used in the libraries have a suffix _8, _16, or _32, as
+ appropriate.
+
+
+INPUT ENCODING
+
+ Input to pcre2test is processed line by line, either by calling the C
+ library's fgets() function, or via the libreadline library (see below).
+ The input is processed using using C's string functions, so must not
+ contain binary zeroes, even though in Unix-like environments, fgets()
+ treats any bytes other than newline as data characters. In some Windows
+ environments character 26 (hex 1A) causes an immediate end of file, and
+ no further data is read.
+
+ For maximum portability, therefore, it is safest to avoid non-printing
+ characters in pcre2test input files. There is a facility for specifying
+ a pattern's characters as hexadecimal pairs, thus making it possible to
+ include binary zeroes in a pattern for testing purposes. Subject lines
+ are processed for backslash escapes, which makes it possible to include
+ any data value.
+
+
+COMMAND LINE OPTIONS
+
+ -8 If the 8-bit library has been built, this option causes it to
+ be used (this is the default). If the 8-bit library has not
+ been built, this option causes an error.
+
+ -16 If the 16-bit library has been built, this option causes it
+ to be used. If only the 16-bit library has been built, this
+ is the default. If the 16-bit library has not been built,
+ this option causes an error.
+
+ -32 If the 32-bit library has been built, this option causes it
+ to be used. If only the 32-bit library has been built, this
+ is the default. If the 32-bit library has not been built,
+ this option causes an error.
+
+ -b Behave as if each pattern has the /fullbincode modifier; the
+ full internal binary form of the pattern is output after com-
+ pilation.
+
+ -C Output the version number of the PCRE2 library, and all
+ available information about the optional features that are
+ included, and then exit with zero exit code. All other
+ options are ignored.
+
+ -C option Output information about a specific build-time option, then
+ exit. This functionality is intended for use in scripts such
+ as RunTest. The following options output the value and set
+ the exit code as indicated:
+
+ ebcdic-nl the code for LF (= NL) in an EBCDIC environment:
+ 0x15 or 0x25
+ 0 if used in an ASCII environment
+ exit code is always 0
+ linksize the configured internal link size (2, 3, or 4)
+ exit code is set to the link size
+ newline the default newline setting:
+ CR, LF, CRLF, ANYCRLF, or ANY
+ exit code is always 0
+ bsr the default setting for what \R matches:
+ ANYCRLF or ANY
+ exit code is always 0
+
+ The following options output 1 for true or 0 for false, and
+ set the exit code to the same value:
+
+ backslash-C \C is supported (not locked out)
+ ebcdic compiled for an EBCDIC environment
+ jit just-in-time support is available
+ pcre2-16 the 16-bit library was built
+ pcre2-32 the 32-bit library was built

+ unicode Unicode support is available
+
+ If an unknown option is given, an error message is output;
+ the exit code is 0.
+
+ -d Behave as if each pattern has the debug modifier; the inter-
+ nal form and information about the compiled pattern is output
+ after compilation; -d is equivalent to -b -i.
+
+ -dfa Behave as if each subject line has the dfa modifier; matching
+ is done using the pcre2_dfa_match() function instead of the
+ default pcre2_match().

+
+ -i Behave as if each pattern has the /info modifier; information
+ about the compiled pattern is given after compilation.
+
+ -jit Behave as if each pattern line has the jit modifier; after
+ successful compilation, each pattern is passed to the just-
+ in-time compiler, if available.
+
+ -pattern modifier-list
+ Behave as if each pattern line contains the given modifiers.
+
+ -q Do not output the version number of pcre2test at the start of
+ execution.

+
+ -subject modifier-list
+ Behave as if each subject line contains the given modifiers.
+
+ -t Run each compile and match many times with a timer, and out-
+ put the resulting times per compile or match. When JIT is
+ used, separate times are given for the initial compile and
+ the JIT compile. You can control the number of iterations
+ that are used for timing by following -t with a number (as a
+ separate item on the command line). For example, "-t 1000"
+ iterates 1000 times. The default is to iterate 500,000 times.
+
+ -tm This is like -t except that it times only the matching phase,
+ not the compile phase.
+
+ -T -TM These behave like -t and -tm, but in addition, at the end of

+
+DESCRIPTION
+
+ If pcre2test is given two filename arguments, it reads from the first
+ and writes to the second. If the first name is "-", input is taken from
+ the standard input. If pcre2test is given only one argument, it reads
+ from that file and writes to stdout. Otherwise, it reads from stdin and
+ writes to stdout.
+
+ When pcre2test is built, a configuration option can specify that it
+ should be linked with the libreadline or libedit library. When this is
+ done, if the input is from a terminal, it is read using the readline()
+ function. This provides line-editing and history facilities. The output
+ from the -help option states whether or not readline() will be used.
+
+ The program handles any number of tests, each of which consists of a
+ set of input lines. Each set starts with a regular expression pattern,
+ followed by any number of subject lines to be matched against that pat-
+ tern. In between sets of test data, command lines that begin with # may
+ appear. This file format, with some restrictions, can also be processed
+ by the perltest.sh script that is distributed with PCRE2 as a means of
+ checking that the behaviour of PCRE2 and Perl is the same.
+
+ When the input is a terminal, pcre2test prompts for each line of input,
+ using "re>" to prompt for regular expression patterns, and "data>" to
+ prompt for subject lines. Command lines starting with # can be entered
+ only in response to the "re>" prompt.
+
+ Each subject line is matched separately and independently. If you want
+ to do multi-line matches, you have to use the \n escape sequence (or \r
+ or \r\n, etc., depending on the newline setting) in a single line of
+ input to encode the newline sequences. There is no limit on the length
+ of subject lines; the input buffer is automatically extended if it is
+ too small. There are replication features that makes it possible to
+ generate long repetitive pattern or subject lines without having to
+ supply them explicitly.
+
+ An empty line or the end of the file signals the end of the subject
+ lines for a test, at which point a new pattern or command line is
+ expected if there is still input to be read.
+
+
+COMMAND LINES
+
+ In between sets of test data, a line that begins with # is interpreted
+ as a command line. If the first character is followed by white space or
+ an exclamation mark, the line is treated as a comment, and ignored.
+ Otherwise, the following commands are recognized:
+
+ #forbid_utf
+
+ Subsequent patterns automatically have the PCRE2_NEVER_UTF and
+ PCRE2_NEVER_UCP options set, which locks out the use of the PCRE2_UTF
+ and PCRE2_UCP options and the use of (*UTF) and (*UCP) at the start of
+ patterns. This command also forces an error if a subsequent pattern
+ contains any occurrences of \P, \p, or \X, which are still supported
+ when PCRE2_UTF is not set, but which require Unicode property support
+ to be included in the library.
+
+ This is a trigger guard that is used in test files to ensure that UTF
+ or Unicode property tests are not accidentally added to files that are
+ used when Unicode support is not included in the library. Setting
+ PCRE2_NEVER_UTF and PCRE2_NEVER_UCP as a default can also be obtained
+ by the use of #pattern; the difference is that #forbid_utf cannot be
+ unset, and the automatic options are not displayed in pattern informa-
+ tion, to avoid cluttering up test output.
+
+ #load <filename>
+
+ This command is used to load a set of precompiled patterns from a file,
+ as described in the section entitled "Saving and restoring compiled
+ patterns" below.
+
+ #newline_default [<newline-list>]
+
+ When PCRE2 is built, a default newline convention can be specified.
+ This determines which characters and/or character pairs are recognized
+ as indicating a newline in a pattern or subject string. The default can
+ be overridden when a pattern is compiled. The standard test files con-
+ tain tests of various newline conventions, but the majority of the
+ tests expect a single linefeed to be recognized as a newline by
+ default. Without special action the tests would fail when PCRE2 is com-
+ piled with either CR or CRLF as the default newline.
+
+ The #newline_default command specifies a list of newline types that are
+ acceptable as the default. The types must be one of CR, LF, CRLF, ANY-
+ CRLF, or ANY (in upper or lower case), for example:
+
+ #newline_default LF Any anyCRLF
+
+ If the default newline is in the list, this command has no effect. Oth-
+ erwise, except when testing the POSIX API, a newline modifier that
+ specifies the first newline convention in the list (LF in the above
+ example) is added to any pattern that does not already have a newline
+ modifier. If the newline list is empty, the feature is turned off. This
+ command is present in a number of the standard test input files.
+
+ When the POSIX API is being tested there is no way to override the
+ default newline convention, though it is possible to set the newline
+ convention from within the pattern. A warning is given if the posix
+ modifier is used when #newline_default would set a default for the non-
+ POSIX API.
+
+ #pattern <modifier-list>
+
+ This command sets a default modifier list that applies to all subse-
+ quent patterns. Modifiers on a pattern can change these settings.
+
+ #perltest
+
+ The appearance of this line causes all subsequent modifier settings to
+ be checked for compatibility with the perltest.sh script, which is used
+ to confirm that Perl gives the same results as PCRE2. Also, apart from
+ comment lines, none of the other command lines are permitted, because
+ they and many of the modifiers are specific to pcre2test, and should
+ not be used in test files that are also processed by perltest.sh. The
+ #perltest command helps detect tests that are accidentally put in the
+ wrong file.
+
+ #pop [<modifiers>]
+
+ This command is used to manipulate the stack of compiled patterns, as
+ described in the section entitled "Saving and restoring compiled pat-
+ terns" below.
+
+ #save <filename>
+
+ This command is used to save a set of compiled patterns to a file, as
+ described in the section entitled "Saving and restoring compiled pat-
+ terns" below.
+
+ #subject <modifier-list>
+
+ This command sets a default modifier list that applies to all subse-
+ quent subject lines. Modifiers on a subject line can change these set-
+ tings.
+
+
+MODIFIER SYNTAX
+
+ Modifier lists are used with both pattern and subject lines. Items in a
+ list are separated by commas followed by optional white space. Trailing
+ whitespace in a modifier list is ignored. Some modifiers may be given
+ for both patterns and subject lines, whereas others are valid only for
+ one or the other. Each modifier has a long name, for example
+ "anchored", and some of them must be followed by an equals sign and a
+ value, for example, "offset=12". Values cannot contain comma charac-
+ ters, but may contain spaces. Modifiers that do not take values may be
+ preceded by a minus sign to turn off a previous setting.
+
+ A few of the more common modifiers can also be specified as single let-
+ ters, for example "i" for "caseless". In documentation, following the
+ Perl convention, these are written with a slash ("the /i modifier") for
+ clarity. Abbreviated modifiers must all be concatenated in the first
+ item of a modifier list. If the first item is not recognized as a long
+ modifier name, it is interpreted as a sequence of these abbreviations.
+ For example:
+
+ /abc/ig,newline=cr,jit=3
+
+ This is a pattern line whose modifier list starts with two one-letter
+ modifiers (/i and /g). The lower-case abbreviated modifiers are the
+ same as used in Perl.
+
+
+PATTERN SYNTAX
+
+ A pattern line must start with one of the following characters (common
+ symbols, excluding pattern meta-characters):
+
+ / ! " ' ` - = _ : ; , % & @ ~
+
+ This is interpreted as the pattern's delimiter. A regular expression
+ may be continued over several input lines, in which case the newline
+ characters are included within it. It is possible to include the delim-
+ iter within the pattern by escaping it with a backslash, for example
+
+ /abc\/def/
+
+ If you do this, the escape and the delimiter form part of the pattern,
+ but since the delimiters are all non-alphanumeric, this does not affect
+ its interpretation. If the terminating delimiter is immediately fol-
+ lowed by a backslash, for example,
+
+ /abc/\
+
+ then a backslash is added to the end of the pattern. This is done to
+ provide a way of testing the error condition that arises if a pattern
+ finishes with a backslash, because
+
+ /abc\/
+
+ is interpreted as the first line of a pattern that starts with "abc/",
+ causing pcre2test to read the next line as a continuation of the regu-
+ lar expression.
+
+ A pattern can be followed by a modifier list (details below).
+
+
+SUBJECT LINE SYNTAX
+
+ Before each subject line is passed to pcre2_match() or
+ pcre2_dfa_match(), leading and trailing white space is removed, and the
+ line is scanned for backslash escapes. The following provide a means of
+ encoding non-printing characters in a visible way:
+
+ \a alarm (BEL, \x07)
+ \b backspace (\x08)
+ \e escape (\x27)
+ \f form feed (\x0c)
+ \n newline (\x0a)
+ \r carriage return (\x0d)
+ \t tab (\x09)
+ \v vertical tab (\x0b)
+ \nnn octal character (up to 3 octal digits); always
+ a byte unless > 255 in UTF-8 or 16-bit or 32-bit mode
+ \o{dd...} octal character (any number of octal digits}
+ \xhh hexadecimal byte (up to 2 hex digits)
+ \x{hh...} hexadecimal character (any number of hex digits)
+
+ The use of \x{hh...} is not dependent on the use of the utf modifier on
+ the pattern. It is recognized always. There may be any number of hexa-
+ decimal digits inside the braces; invalid values provoke error mes-
+ sages.
+
+ Note that \xhh specifies one byte rather than one character in UTF-8
+ mode; this makes it possible to construct invalid UTF-8 sequences for
+ testing purposes. On the other hand, \x{hh} is interpreted as a UTF-8
+ character in UTF-8 mode, generating more than one byte if the value is
+ greater than 127. When testing the 8-bit library not in UTF-8 mode,
+ \x{hh} generates one byte for values less than 256, and causes an error
+ for greater values.
+
+ In UTF-16 mode, all 4-digit \x{hhhh} values are accepted. This makes it
+ possible to construct invalid UTF-16 sequences for testing purposes.
+
+ In UTF-32 mode, all 4- to 8-digit \x{...} values are accepted. This
+ makes it possible to construct invalid UTF-32 sequences for testing
+ purposes.
+
+ There is a special backslash sequence that specifies replication of one
+ or more characters:
+
+ \[<characters>]{<count>}
+
+ This makes it possible to test long strings without having to provide
+ them as part of the file. For example:
+
+ \[abc]{4}
+
+ is converted to "abcabcabcabc". This feature does not support nesting.
+ To include a closing square bracket in the characters, code it as \x5D.
+
+ A backslash followed by an equals sign marks the end of the subject
+ string and the start of a modifier list. For example:
+
+ abc\=notbol,notempty
+
+ If the subject string is empty and \= is followed by whitespace, the
+ line is treated as a comment line, and is not used for matching. For
+ example:
+
+ \= This is a comment.
+ abc\= This is an invalid modifier list.
+
+ A backslash followed by any other non-alphanumeric character just
+ escapes that character. A backslash followed by anything else causes an
+ error. However, if the very last character in the line is a backslash
+ (and there is no modifier list), it is ignored. This gives a way of
+ passing an empty line as data, since a real empty line terminates the
+ data input.
+
+
+PATTERN MODIFIERS
+
+ There are several types of modifier that can appear in pattern lines.
+ Except where noted below, they may also be used in #pattern commands. A
+ pattern's modifier list can add to or override default modifiers that
+ were set by a previous #pattern command.
+
+ Setting compilation options
+
+ The following modifiers set options for pcre2_compile(). The most com-
+ mon ones have single-letter abbreviations. See pcre2api for a descrip-
+ tion of their effects.
+
+ allow_empty_class set PCRE2_ALLOW_EMPTY_CLASS
+ alt_bsux set PCRE2_ALT_BSUX
+ alt_circumflex set PCRE2_ALT_CIRCUMFLEX
+ alt_verbnames set PCRE2_ALT_VERBNAMES
+ anchored set PCRE2_ANCHORED
+ auto_callout set PCRE2_AUTO_CALLOUT
+ /i caseless set PCRE2_CASELESS
+ dollar_endonly set PCRE2_DOLLAR_ENDONLY
+ /s dotall set PCRE2_DOTALL
+ dupnames set PCRE2_DUPNAMES
+ /x extended set PCRE2_EXTENDED
+ firstline set PCRE2_FIRSTLINE
+ match_unset_backref set PCRE2_MATCH_UNSET_BACKREF
+ /m multiline set PCRE2_MULTILINE
+ never_backslash_c set PCRE2_NEVER_BACKSLASH_C
+ never_ucp set PCRE2_NEVER_UCP
+ never_utf set PCRE2_NEVER_UTF
+ no_auto_capture set PCRE2_NO_AUTO_CAPTURE
+ no_auto_possess set PCRE2_NO_AUTO_POSSESS
+ no_dotstar_anchor set PCRE2_NO_DOTSTAR_ANCHOR
+ no_start_optimize set PCRE2_NO_START_OPTIMIZE
+ no_utf_check set PCRE2_NO_UTF_CHECK
+ ucp set PCRE2_UCP
+ ungreedy set PCRE2_UNGREEDY
+ use_offset_limit set PCRE2_USE_OFFSET_LIMIT
+ utf set PCRE2_UTF
+
+ As well as turning on the PCRE2_UTF option, the utf modifier causes all
+ non-printing characters in output strings to be printed using the
+ \x{hh...} notation. Otherwise, those less than 0x100 are output in hex
+ without the curly brackets.
+
+ Setting compilation controls
+
+ The following modifiers affect the compilation process or request
+ information about the pattern:
+
+ bsr=[anycrlf|unicode] specify \R handling
+ /B bincode show binary code without lengths
+ callout_info show callout information
+ debug same as info,fullbincode
+ fullbincode show binary code with lengths
+ /I info show info about compiled pattern
+ hex pattern is coded in hexadecimal
+ jit[=<number>] use JIT
+ jitfast use JIT fast path
+ jitverify verify JIT use
+ locale=<name> use this locale
+ max_pattern_length=<n> set the maximum pattern length
+ memory show memory used
+ newline=<type> set newline type
+ null_context compile with a NULL context
+ parens_nest_limit=<n> set maximum parentheses depth
+ posix use the POSIX API
+ push push compiled pattern onto the stack
+ stackguard=<number> test the stackguard feature
+ tables=[0|1|2] select internal tables
+
+ The effects of these modifiers are described in the following sections.
+
+ Newline and \R handling
+
+ The bsr modifier specifies what \R in a pattern should match. If it is
+ set to "anycrlf", \R matches CR, LF, or CRLF only. If it is set to
+ "unicode", \R matches any Unicode newline sequence. The default is
+ specified when PCRE2 is built, with the default default being Unicode.
+
+ The newline modifier specifies which characters are to be interpreted
+ as newlines, both in the pattern and in subject lines. The type must be
+ one of CR, LF, CRLF, ANYCRLF, or ANY (in upper or lower case).
+
+ Information about a pattern
+
+ The debug modifier is a shorthand for info,fullbincode, requesting all
+ available information.
+
+ The bincode modifier causes a representation of the compiled code to be
+ output after compilation. This information does not contain length and
+ offset values, which ensures that the same output is generated for dif-
+ ferent internal link sizes and different code unit widths. By using
+ bincode, the same regression tests can be used in different environ-
+ ments.
+
+ The fullbincode modifier, by contrast, does include length and offset
+ values. This is used in a few special tests that run only for specific
+ code unit widths and link sizes, and is also useful for one-off tests.
+
+ The info modifier requests information about the compiled pattern
+ (whether it is anchored, has a fixed first character, and so on). The
+ information is obtained from the pcre2_pattern_info() function. Here
+ are some typical examples:
+
+ re> /(?i)(^a|^b)/m,info
+ Capturing subpattern count = 1
+ Compile options: multiline
+ Overall options: caseless multiline
+ First code unit at start or follows newline
+ Subject length lower bound = 1
+
+ re> /(?i)abc/info
+ Capturing subpattern count = 0
+ Compile options: <none>
+ Overall options: caseless
+ First code unit = 'a' (caseless)
+ Last code unit = 'c' (caseless)
+ Subject length lower bound = 3
+
+ "Compile options" are those specified by modifiers; "overall options"
+ have added options that are taken or deduced from the pattern. If both
+ sets of options are the same, just a single "options" line is output;
+ if there are no options, the line is omitted. "First code unit" is
+ where any match must start; if there is more than one they are listed
+ as "starting code units". "Last code unit" is the last literal code
+ unit that must be present in any match. This is not necessarily the
+ last character. These lines are omitted if no starting or ending code
+ units are recorded.
+
+ The callout_info modifier requests information about all the callouts
+ in the pattern. A list of them is output at the end of any other infor-
+ mation that is requested. For each callout, either its number or string
+ is given, followed by the item that follows it in the pattern.
+
+ Passing a NULL context
+
+ Normally, pcre2test passes a context block to pcre2_compile(). If the
+ null_context modifier is set, however, NULL is passed. This is for
+ testing that pcre2_compile() behaves correctly in this case (it uses
+ default values).
+
+ Specifying a pattern in hex
+
+ The hex modifier specifies that the characters of the pattern are to be
+ interpreted as pairs of hexadecimal digits. White space is permitted
+ between pairs. For example:
+
+ /ab 32 59/hex
+
+ This feature is provided as a way of creating patterns that contain
+ binary zero and other non-printing characters. By default, pcre2test
+ passes patterns as zero-terminated strings to pcre2_compile(), giving
+ the length as PCRE2_ZERO_TERMINATED. However, for patterns specified in
+ hexadecimal, the actual length of the pattern is passed.
+
+ Generating long repetitive patterns
+
+ Some tests use long patterns that are very repetitive. Instead of cre-
+ ating a very long input line for such a pattern, you can use a special
+ repetition feature, similar to the one described for subject lines
+ above. If the expand modifier is present on a pattern, parts of the
+ pattern that have the form
+
+ \[<characters>]{<count>}
+
+ are expanded before the pattern is passed to pcre2_compile(). For exam-
+ ple, \[AB]{6000} is expanded to "ABAB..." 6000 times. This construction
+ cannot be nested. An initial "\[" sequence is recognized only if "]{"
+ followed by decimal digits and "}" is found later in the pattern. If
+ not, the characters remain in the pattern unaltered.
+
+ If part of an expanded pattern looks like an expansion, but is really
+ part of the actual pattern, unwanted expansion can be avoided by giving
+ two values in the quantifier. For example, \[AB]{6000,6000} is not rec-
+ ognized as an expansion item.
+
+ If the info modifier is set on an expanded pattern, the result of the
+ expansion is included in the information that is output.
+
+ JIT compilation
+
+ Just-in-time (JIT) compiling is a heavyweight optimization that can
+ greatly speed up pattern matching. See the pcre2jit documentation for
+ details. JIT compiling happens, optionally, after a pattern has been
+ successfully compiled into an internal form. The JIT compiler converts
+ this to optimized machine code. It needs to know whether the match-time
+ options PCRE2_PARTIAL_HARD and PCRE2_PARTIAL_SOFT are going to be used,
+ because different code is generated for the different cases. See the
+ partial modifier in "Subject Modifiers" below for details of how these
+ options are specified for each match attempt.
+
+ JIT compilation is requested by the /jit pattern modifier, which may
+ optionally be followed by an equals sign and a number in the range 0 to
+ 7. The three bits that make up the number specify which of the three
+ JIT operating modes are to be compiled:
+
+ 1 compile JIT code for non-partial matching
+ 2 compile JIT code for soft partial matching
+ 4 compile JIT code for hard partial matching
+
+ The possible values for the /jit modifier are therefore:
+
+ 0 disable JIT
+ 1 normal matching only
+ 2 soft partial matching only
+ 3 normal and soft partial matching
+ 4 hard partial matching only
+ 6 soft and hard partial matching only
+ 7 all three modes
+
+ If no number is given, 7 is assumed. The phrase "partial matching"
+ means a call to pcre2_match() with either the PCRE2_PARTIAL_SOFT or the
+ PCRE2_PARTIAL_HARD option set. Note that such a call may return a com-
+ plete match; the options enable the possibility of a partial match, but
+ do not require it. Note also that if you request JIT compilation only
+ for partial matching (for example, /jit=2) but do not set the partial
+ modifier on a subject line, that match will not use JIT code because
+ none was compiled for non-partial matching.
+
+ If JIT compilation is successful, the compiled JIT code will automati-
+ cally be used when an appropriate type of match is run, except when
+ incompatible run-time options are specified. For more details, see the
+ pcre2jit documentation. See also the jitstack modifier below for a way
+ of setting the size of the JIT stack.
+
+ If the jitfast modifier is specified, matching is done using the JIT
+ "fast path" interface, pcre2_jit_match(), which skips some of the san-
+ ity checks that are done by pcre2_match(), and of course does not work
+ when JIT is not supported. If jitfast is specified without jit, jit=7
+ is assumed.
+
+ If the jitverify modifier is specified, information about the compiled
+ pattern shows whether JIT compilation was or was not successful. If
+ jitverify is specified without jit, jit=7 is assumed. If JIT compila-
+ tion is successful when jitverify is set, the text "(JIT)" is added to
+ the first output line after a match or non match when JIT-compiled code
+ was actually used in the match.
+
+ Setting a locale
+
+ The /locale modifier must specify the name of a locale, for example:
+
+ /pattern/locale=fr_FR
+
+ The given locale is set, pcre2_maketables() is called to build a set of
+ character tables for the locale, and this is then passed to pcre2_com-
+ pile() when compiling the regular expression. The same tables are used
+ when matching the following subject lines. The /locale modifier applies
+ only to the pattern on which it appears, but can be given in a #pattern
+ command if a default is needed. Setting a locale and alternate charac-
+ ter tables are mutually exclusive.
+
+ Showing pattern memory
+
+ The /memory modifier causes the size in bytes of the memory used to
+ hold the compiled pattern to be output. This does not include the size
+ of the pcre2_code block; it is just the actual compiled data. If the
+ pattern is subsequently passed to the JIT compiler, the size of the JIT
+ compiled code is also output. Here is an example:
+
+ re> /a(b)c/jit,memory
+ Memory allocation (code space): 21
+ Memory allocation (JIT code): 1910
+
+
+ Limiting nested parentheses
+
+ The parens_nest_limit modifier sets a limit on the depth of nested
+ parentheses in a pattern. Breaching the limit causes a compilation
+ error. The default for the library is set when PCRE2 is built, but
+ pcre2test sets its own default of 220, which is required for running
+ the standard test suite.
+
+ Limiting the pattern length
+
+ The max_pattern_length modifier sets a limit, in code units, to the
+ length of pattern that pcre2_compile() will accept. Breaching the limit
+ causes a compilation error. The default is the largest number a
+ PCRE2_SIZE variable can hold (essentially unlimited).
+
+ Using the POSIX wrapper API
+
+ The /posix modifier causes pcre2test to call PCRE2 via the POSIX wrap-
+ per API rather than its native API. This supports only the 8-bit
+ library. Note that it does not imply POSIX matching semantics; for
+ more detail see the pcre2posix documentation. When the POSIX API is
+ being used, the following pattern modifiers set options for the reg-
+ comp() function:
+
+ caseless REG_ICASE
+ multiline REG_NEWLINE
+ no_auto_capture REG_NOSUB
+ dotall REG_DOTALL )
+ ungreedy REG_UNGREEDY ) These options are not part of
+ ucp REG_UCP ) the POSIX standard
+ utf REG_UTF8 )
+
+ The regerror_buffsize modifier specifies a size for the error buffer
+ that is passed to regerror() in the event of a compilation error. For
+ example:
+
+ /abc/posix,regerror_buffsize=20
+
+ This provides a means of testing the behaviour of regerror() when the
+ buffer is too small for the error message. If this modifier has not
+ been set, a large buffer is used.
+
+ The aftertext and allaftertext subject modifiers work as described
+ below. All other modifiers cause an error.
+
+ Testing the stack guard feature
+
+ The /stackguard modifier is used to test the use of pcre2_set_com-
+ pile_recursion_guard(), a function that is provided to enable stack
+ availability to be checked during compilation (see the pcre2api docu-
+ mentation for details). If the number specified by the modifier is
+ greater than zero, pcre2_set_compile_recursion_guard() is called to set
+ up callback from pcre2_compile() to a local function. The argument it
+ receives is the current nesting parenthesis depth; if this is greater
+ than the value given by the modifier, non-zero is returned, causing the
+ compilation to be aborted.
+
+ Using alternative character tables
+
+ The value specified for the /tables modifier must be one of the digits
+ 0, 1, or 2. It causes a specific set of built-in character tables to be
+ passed to pcre2_compile(). This is used in the PCRE2 tests to check be-
+ haviour with different character tables. The digit specifies the tables
+ as follows:
+
+ 0 do not pass any special character tables
+ 1 the default ASCII tables, as distributed in
+ pcre2_chartables.c.dist
+ 2 a set of tables defining ISO 8859 characters
+
+ In table 2, some characters whose codes are greater than 128 are iden-
+ tified as letters, digits, spaces, etc. Setting alternate character
+ tables and a locale are mutually exclusive.
+
+ Setting certain match controls
+
+ The following modifiers are really subject modifiers, and are described
+ below. However, they may be included in a pattern's modifier list, in
+ which case they are applied to every subject line that is processed
+ with that pattern. They may not appear in #pattern commands. These mod-
+ ifiers do not affect the compilation process.
+
+ aftertext show text after match
+ allaftertext show text after captures
+ allcaptures show all captures
+ allusedtext show all consulted text
+ /g global global matching
+ mark show mark values
+ replace=<string> specify a replacement string
+ startchar show starting character when relevant
+ substitute_extended use PCRE2_SUBSTITUTE_EXTENDED
+ substitute_overflow_length use PCRE2_SUBSTITUTE_OVERFLOW_LENGTH
+ substitute_unknown_unset use PCRE2_SUBSTITUTE_UNKNOWN_UNSET
+ substitute_unset_empty use PCRE2_SUBSTITUTE_UNSET_EMPTY
+
+ These modifiers may not appear in a #pattern command. If you want them
+ as defaults, set them in a #subject command.
+
+ Saving a compiled pattern
+
+ When a pattern with the push modifier is successfully compiled, it is
+ pushed onto a stack of compiled patterns, and pcre2test expects the
+ next line to contain a new pattern (or a command) instead of a subject
+ line. This facility is used when saving compiled patterns to a file, as
+ described in the section entitled "Saving and restoring compiled pat-
+ terns" below. The push modifier is incompatible with compilation modi-
+ fiers such as global that act at match time. Any that are specified are
+ ignored, with a warning message, except for replace, which causes an
+ error. Note that, jitverify, which is allowed, does not carry through
+ to any subsequent matching that uses this pattern.
+
+
+SUBJECT MODIFIERS
+
+ The modifiers that can appear in subject lines and the #subject command
+ are of two types.
+
+ Setting match options
+
+ The following modifiers set options for pcre2_match() or
+ pcre2_dfa_match(). See pcreapi for a description of their effects.
+
+ anchored set PCRE2_ANCHORED
+ dfa_restart set PCRE2_DFA_RESTART
+ dfa_shortest set PCRE2_DFA_SHORTEST
+ no_utf_check set PCRE2_NO_UTF_CHECK
+ notbol set PCRE2_NOTBOL
+ notempty set PCRE2_NOTEMPTY
+ notempty_atstart set PCRE2_NOTEMPTY_ATSTART
+ noteol set PCRE2_NOTEOL
+ partial_hard (or ph) set PCRE2_PARTIAL_HARD
+ partial_soft (or ps) set PCRE2_PARTIAL_SOFT
+
+ The partial matching modifiers are provided with abbreviations because
+ they appear frequently in tests.
+
+ If the /posix modifier was present on the pattern, causing the POSIX
+ wrapper API to be used, the only option-setting modifiers that have any
+ effect are notbol, notempty, and noteol, causing REG_NOTBOL,
+ REG_NOTEMPTY, and REG_NOTEOL, respectively, to be passed to regexec().
+ Any other modifiers cause an error.
+
+ Setting match controls
+
+ The following modifiers affect the matching process or request addi-
+ tional information. Some of them may also be specified on a pattern
+ line (see above), in which case they apply to every subject line that
+ is matched against that pattern.
+
+ aftertext show text after match
+ allaftertext show text after captures
+ allcaptures show all captures
+ allusedtext show all consulted text (non-JIT only)
+ altglobal alternative global matching
+ callout_capture show captures at callout time
+ callout_data=<n> set a value to pass via callouts
+ callout_fail=<n>[:<m>] control callout failure
+ callout_none do not supply a callout function
+ copy=<number or name> copy captured substring
+ dfa use pcre2_dfa_match()
+ find_limits find match and recursion limits
+ get=<number or name> extract captured substring
+ getall extract all captured substrings
+ /g global global matching
+ jitstack=<n> set size of JIT stack
+ mark show mark values
+ match_limit=<n> set a match limit
+ memory show memory usage
+ null_context match with a NULL context
+ offset=<n> set starting offset
+ offset_limit=<n> set offset limit
+ ovector=<n> set size of output vector
+ recursion_limit=<n> set a recursion limit
+ replace=<string> specify a replacement string
+ startchar show startchar when relevant
+ startoffset=<n> same as offset=<n>
+ substitute_extedded use PCRE2_SUBSTITUTE_EXTENDED
+ substitute_overflow_length use PCRE2_SUBSTITUTE_OVERFLOW_LENGTH
+ substitute_unknown_unset use PCRE2_SUBSTITUTE_UNKNOWN_UNSET
+ substitute_unset_empty use PCRE2_SUBSTITUTE_UNSET_EMPTY
+ zero_terminate pass the subject as zero-terminated
+
+ The effects of these modifiers are described in the following sections.
+
+ Showing more text
+
+ The aftertext modifier requests that as well as outputting the part of
+ the subject string that matched the entire pattern, pcre2test should in
+ addition output the remainder of the subject string. This is useful for
+ tests where the subject contains multiple copies of the same substring.
+ The allaftertext modifier requests the same action for captured sub-
+ strings as well as the main matched substring. In each case the remain-
+ der is output on the following line with a plus character following the
+ capture number.
+
+ The allusedtext modifier requests that all the text that was consulted
+ during a successful pattern match by the interpreter should be shown.
+ This feature is not supported for JIT matching, and if requested with
+ JIT it is ignored (with a warning message). Setting this modifier
+ affects the output if there is a lookbehind at the start of a match, or
+ a lookahead at the end, or if \K is used in the pattern. Characters
+ that precede or follow the start and end of the actual match are indi-
+ cated in the output by '<' or '>' characters underneath them. Here is
+ an example:
+
+ re> /(?<=pqr)abc(?=xyz)/
+ data> 123pqrabcxyz456\=allusedtext
+ 0: pqrabcxyz
+ <<< >>>
+
+ This shows that the matched string is "abc", with the preceding and
+ following strings "pqr" and "xyz" having been consulted during the
+ match (when processing the assertions).
+
+ The startchar modifier requests that the starting character for the
+ match be indicated, if it is different to the start of the matched
+ string. The only time when this occurs is when \K has been processed as
+ part of the match. In this situation, the output for the matched string
+ is displayed from the starting character instead of from the match
+ point, with circumflex characters under the earlier characters. For
+ example:
+
+ re> /abc\Kxyz/
+ data> abcxyz\=startchar
+ 0: abcxyz
+ ^^^
+
+ Unlike allusedtext, the startchar modifier can be used with JIT. How-
+ ever, these two modifiers are mutually exclusive.
+
+ Showing the value of all capture groups
+
+ The allcaptures modifier requests that the values of all potential cap-
+ tured parentheses be output after a match. By default, only those up to
+ the highest one actually used in the match are output (corresponding to
+ the return code from pcre2_match()). Groups that did not take part in
+ the match are output as "<unset>".
+
+ Testing callouts
+
+ A callout function is supplied when pcre2test calls the library match-
+ ing functions, unless callout_none is specified. If callout_capture is
+ set, the current captured groups are output when a callout occurs.
+
+ The callout_fail modifier can be given one or two numbers. If there is
+ only one number, 1 is returned instead of 0 when a callout of that num-
+ ber is reached. If two numbers are given, 1 is returned when callout
+ <n> is reached for the <m>th time. Note that callouts with string argu-
+ ments are always given the number zero. See "Callouts" below for a
+ description of the output when a callout it taken.
+
+ The callout_data modifier can be given an unsigned or a negative num-
+ ber. This is set as the "user data" that is passed to the matching
+ function, and passed back when the callout function is invoked. Any
+ value other than zero is used as a return from pcre2test's callout
+ function.
+
+ Finding all matches in a string
+
+ Searching for all possible matches within a subject can be requested by
+ the global or /altglobal modifier. After finding a match, the matching
+ function is called again to search the remainder of the subject. The
+ difference between global and altglobal is that the former uses the
+ start_offset argument to pcre2_match() or pcre2_dfa_match() to start
+ searching at a new point within the entire string (which is what Perl
+ does), whereas the latter passes over a shortened subject. This makes a
+ difference to the matching process if the pattern begins with a lookbe-
+ hind assertion (including \b or \B).
+
+ If an empty string is matched, the next match is done with the
+ PCRE2_NOTEMPTY_ATSTART and PCRE2_ANCHORED flags set, in order to search
+ for another, non-empty, match at the same point in the subject. If this
+ match fails, the start offset is advanced, and the normal match is
+ retried. This imitates the way Perl handles such cases when using the
+ /g modifier or the split() function. Normally, the start offset is
+ advanced by one character, but if the newline convention recognizes
+ CRLF as a newline, and the current character is CR followed by LF, an
+ advance of two characters occurs.
+
+ Testing substring extraction functions
+
+ The copy and get modifiers can be used to test the pcre2_sub-
+ string_copy_xxx() and pcre2_substring_get_xxx() functions. They can be
+ given more than once, and each can specify a group name or number, for
+ example:
+
+ abcd\=copy=1,copy=3,get=G1
+
+ If the #subject command is used to set default copy and/or get lists,
+ these can be unset by specifying a negative number to cancel all num-
+ bered groups and an empty name to cancel all named groups.
+
+ The getall modifier tests pcre2_substring_list_get(), which extracts
+ all captured substrings.
+
+ If the subject line is successfully matched, the substrings extracted
+ by the convenience functions are output with C, G, or L after the
+ string number instead of a colon. This is in addition to the normal
+ full list. The string length (that is, the return from the extraction
+ function) is given in parentheses after each substring, followed by the
+ name when the extraction was by name.
+
+ Testing the substitution function
+
+ If the replace modifier is set, the pcre2_substitute() function is
+ called instead of one of the matching functions. Note that replacement
+ strings cannot contain commas, because a comma signifies the end of a
+ modifier. This is not thought to be an issue in a test program.
+
+ Unlike subject strings, pcre2test does not process replacement strings
+ for escape sequences. In UTF mode, a replacement string is checked to
+ see if it is a valid UTF-8 string. If so, it is correctly converted to
+ a UTF string of the appropriate code unit width. If it is not a valid
+ UTF-8 string, the individual code units are copied directly. This pro-
+ vides a means of passing an invalid UTF-8 string for testing purposes.
+
+ The following modifiers set options (in additional to the normal match
+ options) for pcre2_substitute():
+
+ global PCRE2_SUBSTITUTE_GLOBAL
+ substitute_extended PCRE2_SUBSTITUTE_EXTENDED
+ substitute_overflow_length PCRE2_SUBSTITUTE_OVERFLOW_LENGTH
+ substitute_unknown_unset PCRE2_SUBSTITUTE_UNKNOWN_UNSET
+ substitute_unset_empty PCRE2_SUBSTITUTE_UNSET_EMPTY
+
+
+ After a successful substitution, the modified string is output, pre-
+ ceded by the number of replacements. This may be zero if there were no
+ matches. Here is a simple example of a substitution test:
+
+ /abc/replace=xxx
+ =abc=abc=
+ 1: =xxx=abc=
+ =abc=abc=\=global
+ 2: =xxx=xxx=
+
+ Subject and replacement strings should be kept relatively short (fewer
+ than 256 characters) for substitution tests, as fixed-size buffers are
+ used. To make it easy to test for buffer overflow, if the replacement
+ string starts with a number in square brackets, that number is passed
+ to pcre2_substitute() as the size of the output buffer, with the
+ replacement string starting at the next character. Here is an example
+ that tests the edge case:
+
+ /abc/
+ 123abc123\=replace=[10]XYZ
+ 1: 123XYZ123
+ 123abc123\=replace=[9]XYZ
+ Failed: error -47: no more memory
+
+ The default action of pcre2_substitute() is to return
+ PCRE2_ERROR_NOMEMORY when the output buffer is too small. However, if
+ the PCRE2_SUBSTITUTE_OVERFLOW_LENGTH option is set (by using the sub-
+ stitute_overflow_length modifier), pcre2_substitute() continues to go
+ through the motions of matching and substituting, in order to compute
+ the size of buffer that is required. When this happens, pcre2test shows
+ the required buffer length (which includes space for the trailing zero)
+ as part of the error message. For example:
+
+ /abc/substitute_overflow_length
+ 123abc123\=replace=[9]XYZ
+ Failed: error -47: no more memory: 10 code units are needed
+
+ A replacement string is ignored with POSIX and DFA matching. Specifying
+ partial matching provokes an error return ("bad option value") from
+ pcre2_substitute().
+
+ Setting the JIT stack size
+
+ The jitstack modifier provides a way of setting the maximum stack size
+ that is used by the just-in-time optimization code. It is ignored if
+ JIT optimization is not being used. The value is a number of kilobytes.
+ Providing a stack that is larger than the default 32K is necessary only
+ for very complicated patterns.
+
+ Setting match and recursion limits
+
+ The match_limit and recursion_limit modifiers set the appropriate lim-
+ its in the match context. These values are ignored when the find_limits
+ modifier is specified.
+
+ Finding minimum limits
+
+ If the find_limits modifier is present, pcre2test calls pcre2_match()
+ several times, setting different values in the match context via
+ pcre2_set_match_limit() and pcre2_set_recursion_limit() until it finds
+ the minimum values for each parameter that allow pcre2_match() to com-
+ plete without error.
+
+ If JIT is being used, only the match limit is relevant. If DFA matching
+ is being used, neither limit is relevant, and this modifier is ignored
+ (with a warning message).
+
+ The match_limit number is a measure of the amount of backtracking that
+ takes place, and learning the minimum value can be instructive. For
+ most simple matches, the number is quite small, but for patterns with
+ very large numbers of matching possibilities, it can become large very
+ quickly with increasing length of subject string. The
+ match_limit_recursion number is a measure of how much stack (or, if
+ PCRE2 is compiled with NO_RECURSE, how much heap) memory is needed to
+ complete the match attempt.
+
+ Showing MARK names
+
+
+ The mark modifier causes the names from backtracking control verbs that
+ are returned from calls to pcre2_match() to be displayed. If a mark is
+ returned for a match, non-match, or partial match, pcre2test shows it.
+ For a match, it is on a line by itself, tagged with "MK:". Otherwise,
+ it is added to the non-match message.
+
+ Showing memory usage
+
+ The memory modifier causes pcre2test to log all memory allocation and
+ freeing calls that occur during a match operation.
+
+ Setting a starting offset
+
+ The offset modifier sets an offset in the subject string at which
+ matching starts. Its value is a number of code units, not characters.
+
+ Setting an offset limit
+
+ The offset_limit modifier sets a limit for unanchored matches. If a
+ match cannot be found starting at or before this offset in the subject,
+ a "no match" return is given. The data value is a number of code units,
+ not characters. When this modifier is used, the use_offset_limit modi-
+ fier must have been set for the pattern; if not, an error is generated.
+
+ Setting the size of the output vector
+
+ The ovector modifier applies only to the subject line in which it
+ appears, though of course it can also be used to set a default in a
+ #subject command. It specifies the number of pairs of offsets that are
+ available for storing matching information. The default is 15.
+
+ A value of zero is useful when testing the POSIX API because it causes
+ regexec() to be called with a NULL capture vector. When not testing the
+ POSIX API, a value of zero is used to cause pcre2_match_data_cre-
+ ate_from_pattern() to be called, in order to create a match block of
+ exactly the right size for the pattern. (It is not possible to create a
+ match block with a zero-length ovector; there is always at least one
+ pair of offsets.)
+
+ Passing the subject as zero-terminated
+
+ By default, the subject string is passed to a native API matching func-
+ tion with its correct length. In order to test the facility for passing
+ a zero-terminated string, the zero_terminate modifier is provided. It
+ causes the length to be passed as PCRE2_ZERO_TERMINATED. (When matching
+ via the POSIX interface, this modifier has no effect, as there is no
+ facility for passing a length.)
+
+ When testing pcre2_substitute(), this modifier also has the effect of
+ passing the replacement string as zero-terminated.
+
+ Passing a NULL context
+
+ Normally, pcre2test passes a context block to pcre2_match(),
+ pcre2_dfa_match() or pcre2_jit_match(). If the null_context modifier is
+ set, however, NULL is passed. This is for testing that the matching
+ functions behave correctly in this case (they use default values). This
+ modifier cannot be used with the find_limits modifier or when testing
+ the substitution function.
+
+
+THE ALTERNATIVE MATCHING FUNCTION
+
+ By default, pcre2test uses the standard PCRE2 matching function,
+ pcre2_match() to match each subject line. PCRE2 also supports an alter-
+ native matching function, pcre2_dfa_match(), which operates in a dif-
+ ferent way, and has some restrictions. The differences between the two
+ functions are described in the pcre2matching documentation.
+
+ If the dfa modifier is set, the alternative matching function is used.
+ This function finds all possible matches at a given point in the sub-
+ ject. If, however, the dfa_shortest modifier is set, processing stops
+ after the first match is found. This is always the shortest possible
+ match.
+
+
+DEFAULT OUTPUT FROM pcre2test
+
+ This section describes the output when the normal matching function,
+ pcre2_match(), is being used.
+
+ When a match succeeds, pcre2test outputs the list of captured sub-
+ strings, starting with number 0 for the string that matched the whole
+ pattern. Otherwise, it outputs "No match" when the return is
+ PCRE2_ERROR_NOMATCH, or "Partial match:" followed by the partially
+ matching substring when the return is PCRE2_ERROR_PARTIAL. (Note that
+ this is the entire substring that was inspected during the partial
+ match; it may include characters before the actual match start if a
+ lookbehind assertion, \K, \b, or \B was involved.)
+
+ For any other return, pcre2test outputs the PCRE2 negative error number
+ and a short descriptive phrase. If the error is a failed UTF string
+ check, the code unit offset of the start of the failing character is
+ also output. Here is an example of an interactive pcre2test run.
+
+ $ pcre2test
+ PCRE2 version 9.00 2014-05-10
+
+ re> /^abc(\d+)/
+ data> abc123
+ 0: abc123
+ 1: 123
+ data> xyz
+ No match
+
+ Unset capturing substrings that are not followed by one that is set are
+ not shown by pcre2test unless the allcaptures modifier is specified. In
+ the following example, there are two capturing substrings, but when the
+ first data line is matched, the second, unset substring is not shown.
+ An "internal" unset substring is shown as "<unset>", as for the second
+ data line.
+
+ re> /(a)|(b)/
+ data> a
+ 0: a
+ 1: a
+ data> b
+ 0: b
+ 1: <unset>
+ 2: b
+
+ If the strings contain any non-printing characters, they are output as
+ \xhh escapes if the value is less than 256 and UTF mode is not set.
+ Otherwise they are output as \x{hh...} escapes. See below for the defi-
+ nition of non-printing characters. If the /aftertext modifier is set,
+ the output for substring 0 is followed by the the rest of the subject
+ string, identified by "0+" like this:
+
+ re> /cat/aftertext
+ data> cataract
+ 0: cat
+ 0+ aract
+
+ If global matching is requested, the results of successive matching
+ attempts are output in sequence, like this:
+
+ re> /\Bi(\w\w)/g
+ data> Mississippi
+ 0: iss
+ 1: ss
+ 0: iss
+ 1: ss
+ 0: ipp
+ 1: pp
+
+ "No match" is output only if the first match attempt fails. Here is an
+ example of a failure message (the offset 4 that is specified by the
+ offset modifier is past the end of the subject string):
+
+ re> /xyz/
+ data> xyz\=offset=4
+ Error -24 (bad offset value)
+
+ Note that whereas patterns can be continued over several lines (a plain
+ ">" prompt is used for continuations), subject lines may not. However
+ newlines can be included in a subject by means of the \n escape (or \r,
+ \r\n, etc., depending on the newline sequence setting).
+
+
+OUTPUT FROM THE ALTERNATIVE MATCHING FUNCTION
+
+ When the alternative matching function, pcre2_dfa_match(), is used, the
+ output consists of a list of all the matches that start at the first
+ point in the subject where there is at least one match. For example:
+
+ re> /(tang|tangerine|tan)/
+ data> yellow tangerine\=dfa
+ 0: tangerine
+ 1: tang
+ 2: tan
+
+ Using the normal matching function on this data finds only "tang". The
+ longest matching string is always given first (and numbered zero).
+ After a PCRE2_ERROR_PARTIAL return, the output is "Partial match:",
+ followed by the partially matching substring. Note that this is the
+ entire substring that was inspected during the partial match; it may
+ include characters before the actual match start if a lookbehind asser-
+ tion, \b, or \B was involved. (\K is not supported for DFA matching.)
+
+ If global matching is requested, the search for further matches resumes
+ at the end of the longest match. For example:
+
+ re> /(tang|tangerine|tan)/g
+ data> yellow tangerine and tangy sultana\=dfa
+ 0: tangerine
+ 1: tang
+ 2: tan
+ 0: tang
+ 1: tan
+ 0: tan
+
+ The alternative matching function does not support substring capture,
+ so the modifiers that are concerned with captured substrings are not
+ relevant.
+
+
+RESTARTING AFTER A PARTIAL MATCH
+
+ When the alternative matching function has given the PCRE2_ERROR_PAR-
+ TIAL return, indicating that the subject partially matched the pattern,
+ you can restart the match with additional subject data by means of the
+ dfa_restart modifier. For example:
+
+ re> /^\d?\d(jan|feb|mar|apr|may|jun|jul|aug|sep|oct|nov|dec)\d\d$/
+ data> 23ja\=P,dfa
+ Partial match: 23ja
+ data> n05\=dfa,dfa_restart
+ 0: n05
+
+ For further information about partial matching, see the pcre2partial
+ documentation.
+
+
+CALLOUTS
+
+ If the pattern contains any callout requests, pcre2test's callout func-
+ tion is called during matching unless callout_none is specified. This
+ works with both matching functions.
+
+ The callout function in pcre2test returns zero (carry on matching) by
+ default, but you can use a callout_fail modifier in a subject line (as
+ described above) to change this and other parameters of the callout.
+
+ Inserting callouts can be helpful when using pcre2test to check compli-
+ cated regular expressions. For further information about callouts, see
+ the pcre2callout documentation.
+
+ The output for callouts with numerical arguments and those with string
+ arguments is slightly different.
+
+ Callouts with numerical arguments
+
+ By default, the callout function displays the callout number, the start
+ and current positions in the subject text at the callout time, and the
+ next pattern item to be tested. For example:
+
+ --->pqrabcdef
+ 0 ^ ^ \d
+
+ This output indicates that callout number 0 occurred for a match
+ attempt starting at the fourth character of the subject string, when
+ the pointer was at the seventh character, and when the next pattern
+ item was \d. Just one circumflex is output if the start and current
+ positions are the same.
+
+ Callouts numbered 255 are assumed to be automatic callouts, inserted as
+ a result of the /auto_callout pattern modifier. In this case, instead
+ of showing the callout number, the offset in the pattern, preceded by a
+ plus, is output. For example:
+
+ re> /\d?[A-E]\*/auto_callout
+ data> E*
+ --->E*
+ +0 ^ \d?
+ +3 ^ [A-E]
+ +8 ^^ \*
+ +10 ^ ^
+ 0: E*
+
+ If a pattern contains (*MARK) items, an additional line is output when-
+ ever a change of latest mark is passed to the callout function. For
+ example:
+
+ re> /a(*MARK:X)bc/auto_callout
+ data> abc
+ --->abc
+ +0 ^ a
+ +1 ^^ (*MARK:X)
+ +10 ^^ b
+ Latest Mark: X
+ +11 ^ ^ c
+ +12 ^ ^
+ 0: abc
+
+ The mark changes between matching "a" and "b", but stays the same for
+ the rest of the match, so nothing more is output. If, as a result of
+ backtracking, the mark reverts to being unset, the text "<unset>" is
+ output.
+
+ Callouts with string arguments
+
+ The output for a callout with a string argument is similar, except that
+ instead of outputting a callout number before the position indicators,
+ the callout string and its offset in the pattern string are output
+ before the reflection of the subject string, and the subject string is
+ reflected for each callout. For example:
+
+ re> /^ab(?C'first')cd(?C"second")ef/
+ data> abcdefg
+ Callout (7): 'first'
+ --->abcdefg
+ ^ ^ c
+ Callout (20): "second"
+ --->abcdefg
+ ^ ^ e
+ 0: abcdef
+
+
+NON-PRINTING CHARACTERS
+
+ When pcre2test is outputting text in the compiled version of a pattern,
+ bytes other than 32-126 are always treated as non-printing characters
+ and are therefore shown as hex escapes.
+
+ When pcre2test is outputting text that is a matched part of a subject
+ string, it behaves in the same way, unless a different locale has been
+ set for the pattern (using the /locale modifier). In this case, the
+ isprint() function is used to distinguish printing and non-printing
+ characters.
+
+
+SAVING AND RESTORING COMPILED PATTERNS
+
+ It is possible to save compiled patterns on disc or elsewhere, and
+ reload them later, subject to a number of restrictions. JIT data cannot
+ be saved. The host on which the patterns are reloaded must be running
+ the same version of PCRE2, with the same code unit width, and must also
+ have the same endianness, pointer width and PCRE2_SIZE type. Before
+ compiled patterns can be saved they must be serialized, that is, con-
+ verted to a stream of bytes. A single byte stream may contain any num-
+ ber of compiled patterns, but they must all use the same character
+ tables. A single copy of the tables is included in the byte stream (its
+ size is 1088 bytes).
+
+ The functions whose names begin with pcre2_serialize_ are used for
+ serializing and de-serializing. They are described in the pcre2serial-
+ ize documentation. In this section we describe the features of
+ pcre2test that can be used to test these functions.
+
+ When a pattern with push modifier is successfully compiled, it is
+ pushed onto a stack of compiled patterns, and pcre2test expects the
+ next line to contain a new pattern (or command) instead of a subject
+ line. By this means, a number of patterns can be compiled and retained.
+ The push modifier is incompatible with posix, and control modifiers
+ that act at match time are ignored (with a message). The jitverify mod-
+ ifier applies only at compile time. The command
+
+ #save <filename>
+
+ causes all the stacked patterns to be serialized and the result written
+ to the named file. Afterwards, all the stacked patterns are freed. The
+ command
+
+ #load <filename>
+
+ reads the data in the file, and then arranges for it to be de-serial-
+ ized, with the resulting compiled patterns added to the pattern stack.
+ The pattern on the top of the stack can be retrieved by the #pop com-
+ mand, which must be followed by lines of subjects that are to be
+ matched with the pattern, terminated as usual by an empty line or end
+ of file. This command may be followed by a modifier list containing
+ only control modifiers that act after a pattern has been compiled. In
+ particular, hex, posix, and push are not allowed, nor are any option-
+ setting modifiers. The JIT modifiers are, however permitted. Here is
+ an example that saves and reloads two patterns.
+
+ /abc/push
+ /xyz/push
+ #save tempfile
+ #load tempfile
+ #pop info
+ xyz
+
+ #pop jit,bincode
+ abc
+
+ If jitverify is used with #pop, it does not automatically imply jit,
+ which is different behaviour from when it is used on a pattern.

+.TH PCRE2UNICODE 3 "16 October 2015" "PCRE2 10.21"
+.SH NAME
+PCRE - Perl-compatible regular expressions (revised API)
+.SH "UNICODE AND UTF SUPPORT"
+.rs
+.sp
+When PCRE2 is built with Unicode support (which is the default), it has
+knowledge of Unicode character properties and can process text strings in
+UTF-8, UTF-16, or UTF-32 format (depending on the code unit width). However, by
+default, PCRE2 assumes that one code unit is one character. To process a
+pattern as a UTF string, where a character may require more than one code unit,
+you must call
+.\" HREF
+\fBpcre2_compile()\fP
+.\"
+with the PCRE2_UTF option flag, or the pattern must start with the sequence
+(*UTF). When either of these is the case, both the pattern and any subject
+strings that are matched against it are treated as UTF strings instead of
+strings of individual one-code-unit characters.
+.P
+If you do not need Unicode support you can build PCRE2 without it, in which
+case the library will be smaller.
+.
+.
+.SH "UNICODE PROPERTY SUPPORT"
+.rs
+.sp
+When PCRE2 is built with Unicode support, the escape sequences \ep{..},
+\eP{..}, and \eX can be used. The Unicode properties that can be tested are
+limited to the general category properties such as Lu for an upper case letter
+or Nd for a decimal number, the Unicode script names such as Arabic or Han, and
+the derived properties Any and L&. Full lists are given in the
+.\" HREF
+\fBpcre2pattern\fP
+.\"
+and
+.\" HREF
+\fBpcre2syntax\fP
+.\"
+documentation. Only the short names for properties are supported. For example,
+\ep{L} matches a letter. Its Perl synonym, \ep{Letter}, is not supported.
+Furthermore, in Perl, many properties may optionally be prefixed by "Is", for
+compatibility with Perl 5.6. PCRE does not support this.
+.
+.
+.SH "WIDE CHARACTERS AND UTF MODES"
+.rs
+.sp
+Codepoints less than 256 can be specified in patterns by either braced or
+unbraced hexadecimal escape sequences (for example, \ex{b3} or \exb3). Larger
+values have to use braced sequences. Unbraced octal code points up to \e777 are
+also recognized; larger ones can be coded using \eo{...}.
+.P
+In UTF modes, repeat quantifiers apply to complete UTF characters, not to
+individual code units.
+.P
+In UTF modes, the dot metacharacter matches one UTF character instead of a
+single code unit.
+.P
+The escape sequence \eC can be used to match a single code unit, in a UTF mode,
+but its use can lead to some strange effects because it breaks up multi-unit
+characters (see the description of \eC in the
+.\" HREF
+\fBpcre2pattern\fP
+.\"
+documentation). The use of \eC is not supported by the alternative matching
+function \fBpcre2_dfa_match()\fP when in UTF mode. Its use provokes a
+match-time error. The JIT optimization also does not support \eC in UTF mode.
+If JIT optimization is requested for a UTF pattern that contains \eC, it will
+not succeed, and so the matching will be carried out by the normal interpretive
+function.
+.P
+The character escapes \eb, \eB, \ed, \eD, \es, \eS, \ew, and \eW correctly test
+characters of any code value, but, by default, the characters that PCRE2
+recognizes as digits, spaces, or word characters remain the same set as in
+non-UTF mode, all with code points less than 256. This remains true even when
+PCRE2 is built to include Unicode support, because to do otherwise would slow
+down matching in many common cases. Note that this also applies to \eb
+and \eB, because they are defined in terms of \ew and \eW. If you want
+to test for a wider sense of, say, "digit", you can use explicit Unicode
+property tests such as \ep{Nd}. Alternatively, if you set the PCRE2_UCP option,
+the way that the character escapes work is changed so that Unicode properties
+are used to determine which characters match. There are more details in the
+section on
+.\" HTML <a href="pcre2pattern.html#genericchartypes">
+.\" </a>
+generic character types
+.\"
+in the
+.\" HREF
+\fBpcre2pattern\fP
+.\"
+documentation.
+.P
+Similarly, characters that match the POSIX named character classes are all
+low-valued characters, unless the PCRE2_UCP option is set.
+.P
+However, the special horizontal and vertical white space matching escapes (\eh,
+\eH, \ev, and \eV) do match all the appropriate Unicode characters, whether or
+not PCRE2_UCP is set.
+.P
+Case-insensitive matching in UTF mode makes use of Unicode properties. A few
+Unicode characters such as Greek sigma have more than two codepoints that are
+case-equivalent, and these are treated as such.
+.
+.
+.SH "VALIDITY OF UTF STRINGS"
+.rs
+.sp
+When the PCRE2_UTF option is set, the strings passed as patterns and subjects
+are (by default) checked for validity on entry to the relevant functions.
+If an invalid UTF string is passed, an negative error code is returned. The
+code unit offset to the offending character can be extracted from the match
+data block by calling \fBpcre2_get_startchar()\fP, which is used for this
+purpose after a UTF error.
+.P
+UTF-16 and UTF-32 strings can indicate their endianness by special code knows
+as a byte-order mark (BOM). The PCRE2 functions do not handle this, expecting
+strings to be in host byte order.
+.P
+A UTF string is checked before any other processing takes place. In the case of
+\fBpcre2_match()\fP and \fBpcre2_dfa_match()\fP calls with a non-zero starting
+offset, the check is applied only to that part of the subject that could be
+inspected during matching, and there is a check that the starting offset points
+to the first code unit of a character or to the end of the subject. If there
+are no lookbehind assertions in the pattern, the check starts at the starting
+offset. Otherwise, it starts at the length of the longest lookbehind before the
+starting offset, or at the start of the subject if there are not that many
+characters before the starting offset. Note that the sequences \eb and \eB are
+one-character lookbehinds.
+.P
+In addition to checking the format of the string, there is a check to ensure
+that all code points lie in the range U+0 to U+10FFFF, excluding the surrogate
+area. The so-called "non-character" code points are not excluded because
+Unicode corrigendum #9 makes it clear that they should not be.
+.P
+Characters in the "Surrogate Area" of Unicode are reserved for use by UTF-16,
+where they are used in pairs to encode code points with values greater than
+0xFFFF. The code points that are encoded by UTF-16 pairs are available
+independently in the UTF-8 and UTF-32 encodings. (In other words, the whole
+surrogate thing is a fudge for UTF-16 which unfortunately messes up UTF-8 and
+UTF-32.)
+.P
+In some situations, you may already know that your strings are valid, and
+therefore want to skip these checks in order to improve performance, for
+example in the case of a long subject string that is being scanned repeatedly.
+If you set the PCRE2_NO_UTF_CHECK option at compile time or at match time,
+PCRE2 assumes that the pattern or subject it is given (respectively) contains
+only valid UTF code unit sequences.
+.P
+Passing PCRE2_NO_UTF_CHECK to \fBpcre2_compile()\fP just disables the check for
+the pattern; it does not also apply to subject strings. If you want to disable
+the check for a subject string you must pass this option to \fBpcre2_match()\fP
+or \fBpcre2_dfa_match()\fP.
+.P
+If you pass an invalid UTF string when PCRE2_NO_UTF_CHECK is set, the result
+is undefined and your program may crash or loop indefinitely.

+ PCRE2_ERROR_UTF8_ERR5
+.sp
+The string ends with a truncated UTF-8 character; the code specifies how many
+bytes are missing (1 to 5). Although RFC 3629 restricts UTF-8 characters to be
+no longer than 4 bytes, the encoding scheme (originally defined by RFC 2279)
+allows for up to 6 bytes, and this is checked first; hence the possibility of

+A 2-, 3-, 4-, 5-, or 6-byte character is "overlong", that is, it codes for a
+value that can be represented by fewer bytes, which is invalid. For example,
+the two bytes 0xc0, 0xae give the value 0x2e, whose correct coding uses just
+one byte.
+.sp
+ PCRE2_ERROR_UTF8_ERR20
+.sp
+The two most significant bits of the first byte of a character have the binary

+## ------ ##
+## Usage. ##
+## ------ ##
+
+# This file is a library for parsing options in your shell scripts along
+# with assorted other useful supporting features that you can make use
+# of too.
+#
+# For the simplest scripts you might need only:
+#
+# #!/bin/sh
+# . relative/path/to/funclib.sh
+# . relative/path/to/options-parser
+# scriptversion=1.0
+# func_options ${1+"$@"}
+# eval set dummy "$func_options_result"; shift
+# ...rest of your script...
+#
+# In order for the '--version' option to work, you will need to have a
+# suitably formatted comment like the one at the top of this file
+# starting with '# Written by ' and ending with '# warranty; '.
+#
+# For '-h' and '--help' to work, you will also need a one line
+# description of your script's purpose in a comment directly above the
+# '# Written by ' line, like the one at the top of this file.
+#
+# The default options also support '--debug', which will turn on shell
+# execution tracing (see the comment above debug_cmd below for another
+# use), and '--verbose' and the func_verbose function to allow your script
+# to display verbose messages only when your user has specified
+# '--verbose'.
+#
+# After sourcing this file, you can plug processing for additional
+# options by amending the variables from the 'Configuration' section
+# below, and following the instructions in the 'Option parsing'
+# section further down.
+
+## -------------- ##
+## Configuration. ##
+## -------------- ##
+
+# You should override these variables in your script after sourcing this
+# file so that they reflect the customisations you have added to the
+# option parser.
+
+# The usage line for option parsing errors and the start of '-h' and
+# '--help' output messages. You can embed shell variables for delayed
+# expansion at the time the message is displayed, but you will need to
+# quote other shell meta-characters carefully to prevent them being
+# expanded when the contents are evaled.
+usage='$progpath [OPTION]...'
+
+# Short help message in response to '-h' and '--help'. Add to this or
+# override it after sourcing this library to reflect the full set of
+# options your script accepts.
+usage_message="\
+ --debug enable verbose shell tracing
+ -W, --warnings=CATEGORY
+ report the warnings falling in CATEGORY [all]
+ -v, --verbose verbosely report processing
+ --version print version information and exit
+ -h, --help print short or long help message and exit
+"

+# SYNOPSIS
+#
+# AX_PTHREAD([ACTION-IF-FOUND[, ACTION-IF-NOT-FOUND]])
+#
+# DESCRIPTION
+#
+# This macro figures out how to build C programs using POSIX threads. It
+# sets the PTHREAD_LIBS output variable to the threads library and linker
+# flags, and the PTHREAD_CFLAGS output variable to any special C compiler
+# flags that are needed. (The user can also force certain compiler
+# flags/libs to be tested by setting these environment variables.)
+#
+# Also sets PTHREAD_CC to any special C compiler that is needed for
+# multi-threaded programs (defaults to the value of CC otherwise). (This
+# is necessary on AIX to use the special cc_r compiler alias.)
+#
+# NOTE: You are assumed to not only compile your program with these flags,
+# but also link it with them as well. e.g. you should link with
+# $PTHREAD_CC $CFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS $LIBS
+#
+# If you are only building threads programs, you may wish to use these
+# variables in your default LIBS, CFLAGS, and CC:
+#
+# LIBS="$PTHREAD_LIBS $LIBS"
+# CFLAGS="$CFLAGS $PTHREAD_CFLAGS"
+# CC="$PTHREAD_CC"
+#
+# In addition, if the PTHREAD_CREATE_JOINABLE thread-attribute constant
+# has a nonstandard name, defines PTHREAD_CREATE_JOINABLE to that name
+# (e.g. PTHREAD_CREATE_UNDETACHED on AIX).
+#
+# Also HAVE_PTHREAD_PRIO_INHERIT is defined if pthread is found and the
+# PTHREAD_PRIO_INHERIT symbol is defined when compiling with
+# PTHREAD_CFLAGS.
+#
+# ACTION-IF-FOUND is a list of shell commands to run if a threads library
+# is found, and ACTION-IF-NOT-FOUND is a list of commands to run it if it
+# is not found. If ACTION-IF-FOUND is not specified, the default action
+# will define HAVE_PTHREAD.
+#
+# Please let the authors know if this macro fails on any platform, or if
+# you have any other suggestions or comments. This macro was based on work
+# by SGJ on autoconf scripts for FFTW (http://www.fftw.org/) (with help
+# from M. Frigo), as well as ac_pthread and hb_pthread macros posted by
+# Alejandro Forero Cuervo to the autoconf macro repository. We are also
+# grateful for the helpful feedback of numerous users.

+# serial 5 lt~obsolete.m4
+
+# These exist entirely to fool aclocal when bootstrapping libtool.
+#
+# In the past libtool.m4 has provided macros via AC_DEFUN (or AU_DEFUN),
+# which have later been changed to m4_define as they aren't part of the
+# exported API, or moved to Autoconf or Automake where they belong.
+#
+# The trouble is, aclocal is a bit thick. It'll see the old AC_DEFUN
+# in /usr/share/aclocal/libtool.m4 and remember it, then when it sees us
+# using a macro with the same name in our local m4/libtool.m4 it'll
+# pull the old libtool.m4 in (it doesn't see our shiny new m4_define
+# and doesn't know about Autoconf macros at all.)
+#
+# So we provide this file, which has a silly filename so it's always
+# included after everything else. This provides aclocal with the
+# AC_DEFUNs it wants, but when m4 processes it, it doesn't do anything
+# because those macros already exist, or will be overwritten later.
+# We use AC_DEFUN over AU_DEFUN for compatibility with aclocal-1.6.
+#
+# Anytime we withdraw an AC_DEFUN or AU_DEFUN, remember to add it here.
+# Yes, that means every name once taken will need to remain here until
+# we give up compatibility with versions before 1.7, at which point
+# we need to keep only those names which we still refer to.
+
+# This is to help aclocal find these macros, as it can't see m4_define.

+#
+# The remaining arguments, if any, are passed to Perl. They are an input file
+# and an output file. If there is one argument, the output is written to
+# STDOUT. If Perl receives no arguments, it opens /dev/tty as input, and writes

+
+In environments that support the GNU autotools, config.h.in is converted into
+config.h by the "configure" script. In environments that use CMake,

+need them. You must then add -DHAVE_CONFIG_H to all of your compile commands,
+so that config.h is included at the start of every source.
+
+Alternatively, you can avoid editing by using -D on the compiler command line
+to set the macro values. In this case, you do not have to set -DHAVE_CONFIG_H,
+but if you do, default values will be taken from config.h for non-boolean
+macros that are not defined on the command line.
+
+Boolean macros such as HAVE_STDLIB_H and SUPPORT_PCRE2_8 should either be defined
+(conventionally to 1) for TRUE, and not defined at all for FALSE. All such
+macros are listed as a commented #undef in config.h.generic. Macros such as
+MATCH_LIMIT, whose actual value is relevant, have defaults defined, but are
+surrounded by #ifndef/#endif lines so that the value can be overridden by -D.

+macros that are not defined on the command line.
+
+Boolean macros such as HAVE_STDLIB_H and SUPPORT_PCRE2_8 should either be defined
+(conventionally to 1) for TRUE, and not defined at all for FALSE. All such

+MATCH_LIMIT, whose actual value is relevant, have defaults defined, but are
+surrounded by #ifndef/#endif lines so that the value can be overridden by -D.
+
+PCRE2 uses memmove() if HAVE_MEMMOVE is defined; otherwise it uses bcopy() if
+HAVE_BCOPY is defined. If your system has neither bcopy() nor memmove(), make
+sure both macros are undefined; an emulation function will then be used. */

+overrun. The code does, however, check for an overrun, which can occur for
+pathological patterns. The size of the workspace depends on LINK_SIZE because
+the length of compiled items varies with this.
+
+In the real compile phase, the workspace is used for remembering data about
+numbered groups, provided there are not too many of them (if there are, extra
+memory is acquired). For this phase the memory must be 32-bit aligned. Having

+
+This function is also called from pcre2_substitute() to handle escape sequences

+
+There is one "trick" case: when a sequence such as [[:>:]] or \s in UCP mode is

+backslash (which is usually does), ptrend does not point to its end - it still
+points to the end of the whole pattern. However, we can detect this case
+because cb->nestptr[0] will be non-NULL. The nested sequences are all zero-
+terminated and there are only ever two levels of nesting.

+encountered in a character class. It checks whether this is followed by a
+sequence of characters terminated by a matching ":]" or ".]" or "=]". If we
+reach an unescaped ']' without the special preceding character, return FALSE.
+
+Originally, this function only recognized a sequence of letters between the
+terminators, but it seems that Perl recognizes any sequence of characters,
+though of course unknown POSIX names are subsequently rejected. Perl gives an
+"Unknown POSIX class" error for [:f\oo:] for example, where previously PCRE
+didn't consider this to be a POSIX class. Likewise for [:1234:].
+
+The problem in trying to be exactly like Perl is in the handling of escapes. We
+have to be sure that [abc[:x\]pqr] is *not* treated as containing a POSIX
+class, but [abc[:x\]pqr:]] is (so that an error can be generated). The code
+below handles the special cases \\ and \], but does not try to do any other
+escape processing. This makes it different from Perl for cases such as
+[:l\ower:] where Perl recognizes it as the POSIX class "lower" but PCRE does
+not recognize "l\ower". This is a lesser evil than not diagnosing bad classes
+when Perl does, I think.
+
+A user pointed out that PCRE was rejecting [:a[:digit:]] whereas Perl was not.
+It seems that the appearance of a nested POSIX class supersedes an apparent
+external class. For example, [:a[:digit:]b:] matches "a", "b", ":", or
+a digit. This is handled by returning FALSE if the start of a new group with
+the same terminator is encountered, since the next closing sequence must close
+the nested group, not the outer one.
+
+In Perl, unescaped square brackets may also appear as part of class names. For
+example, [:a[:abc]b:] gives unknown POSIX class "[:abc]b:]". However, for
+[:a[:abc]b][b:] it gives unknown POSIX class "[:abc]b][b:]", which does not
+seem right at all. PCRE does not allow closing square brackets in POSIX class
+names.

+/* This module contains the external function pcre2_dfa_match(), which is an
+alternative matching function that uses a sort of DFA algorithm (not a true
+FSM). This is NOT Perl-compatible, but it has advantages in certain
+applications. */
+
+
+/* NOTE ABOUT PERFORMANCE: A user of this function sent some code that improved
+the performance of his patterns greatly. I could not use it as it stood, as it
+was not thread safe, and made assumptions about pattern sizes. Also, it caused
+test 7 to loop, and test 9 to crash with a segfault.
+
+The issue is the check for duplicate states, which is done by a simple linear
+search up the state list. (Grep for "duplicate" below to find the code.) For
+many patterns, there will never be many states active at one time, so a simple
+linear search is fine. In patterns that have many active states, it might be a
+bottleneck. The suggested code used an indexing scheme to remember which states
+had previously been used for each character, and avoided the linear search when
+it knew there was no chance of a duplicate. This was implemented when adding
+states to the state lists.
+
+I wrote some thread-safe, not-limited code to try something similar at the time
+of checking for duplicates (instead of when adding states), using index vectors
+on the stack. It did give a 13% improvement with one specially constructed
+pattern for certain subject strings, but on other strings and on many of the
+simpler patterns in the test suite it did worse. The major problem, I think,
+was the extra time to initialize the index. This had to be done for each call
+of internal_dfa_match(). (The supplied patch used a static vector, initialized
+only once - I suspect this was the cause of the problems with the tests.)
+
+Overall, I concluded that the gains in some cases did not outweigh the losses
+in others, so I abandoned this code. */

+would need different lookups depending on whether PCRE2_UTF was set or not.
+This would make it impossible to use characters in switch/case statements,

+Short summary about the backtracking mechanism empolyed by the jit code generator:
+
+The code generator follows the recursive nature of the PERL compatible regular
+expressions. The basic blocks of regular expressions are condition checkers
+whose execute different commands depending on the result of the condition check.
+The relationship between the operators can be horizontal (concatenation) and
+vertical (sub-expression) (See struct backtrack_common for more details).
+
+ 'ab' - 'a' and 'b' regexps are concatenated
+ 'a+' - 'a' is the sub-expression of the '+' operator
+
+The condition checkers are boolean (true/false) checkers. Machine code is generated
+for the checker itself and for the actions depending on the result of the checker.
+The 'true' case is called as the matching path (expected path), and the other is called as
+the 'backtrack' path. Branch instructions are expesive for all CPUs, so we avoid taken
+branches on the matching path.
+
+ Greedy star operator (*) :
+ Matching path: match happens.
+ Backtrack path: match failed.
+ Non-greedy star operator (*?) :
+ Matching path: no need to perform a match.
+ Backtrack path: match is required.
+
+The following example shows how the code generated for a capturing bracket
+with two alternatives. Let A, B, C, D are arbirary regular expressions, and
+we have the following regular expression:
+
+ A(B|C)D
+
+The generated code will be the following:
+
+ A matching path
+ '(' matching path (pushing arguments to the stack)
+ B matching path
+ ')' matching path (pushing arguments to the stack)
+ D matching path
+ return with successful match
+
+ D backtrack path
+ ')' backtrack path (If we arrived from "C" jump to the backtrack of "C")
+ B backtrack path
+ C expected path
+ jump to D matching path
+ C backtrack path
+ A backtrack path
+
+ Notice, that the order of backtrack code paths are the opposite of the fast
+ code paths. In this way the topmost value on the stack is always belong
+ to the current backtrack code path. The backtrack path must check
+ whether there is a next alternative. If so, it needs to jump back to
+ the matching path eventually. Otherwise it needs to clear out its own stack
+ frame and continue the execution on the backtrack code paths.
+*/
+
+/*
+Saved stack frames:
+
+Atomic blocks and asserts require reloading the values of private data
+when the backtrack mechanism performed. Because of OP_RECURSE, the data
+are not necessarly known in compile time, thus we need a dynamic restore
+mechanism.
+
+The stack frames are stored in a chain list, and have the following format:
+([ capturing bracket offset ][ start value ][ end value ])+ ... [ 0 ] [ previous head ]
+
+Thus we can restore the private data to a particular point in the stack.

+****************************************************************************
+ RECURSION IN THE match() FUNCTION
+
+The match() function is highly recursive, though not every recursive call
+increases the recursion depth. Nevertheless, some regular expressions can cause
+it to recurse to a great depth. I was writing for Unix, so I just let it call
+itself recursively. This uses the stack for saving everything that has to be
+saved for a recursive call. On Unix, the stack can be large, and this works
+fine.
+
+It turns out that on some non-Unix-like systems there are problems with
+programs that use a lot of stack. (This despite the fact that every last chip
+has oodles of memory these days, and techniques for extending the stack have
+been known for decades.) So....
+
+There is a fudge, triggered by defining HEAP_MATCH_RECURSE, which avoids
+recursive calls by keeping local variables that need to be preserved in blocks
+of memory on the heap instead instead of on the stack. Macros are used to
+achieve this so that the actual code doesn't look very different to what it
+always used to.
+
+The original heap-recursive code used longjmp(). However, it seems that this
+can be very slow on some operating systems. Following a suggestion from Stan
+Switzer, the use of longjmp() has been abolished, at the cost of having to
+provide a unique number for each call to RMATCH. There is no way of generating
+a sequence of numbers at compile time in C. I have given them names, to make
+them stand out more clearly.
+
+Crude tests on x86 Linux show a small speedup of around 5-8%. However, on
+FreeBSD, avoiding longjmp() more than halves the time taken to run the standard
+tests. Furthermore, not using longjmp() means that local dynamic variables
+don't have indeterminate values; this has meant that the frame size can be
+reduced because the result can be "passed back" by straight setting of the
+variable instead of being passed in the frame.

+the 255 bit to be set. When calling set[_not]_type_bits() in UTF-8 (sic) mode
+we pass a value of 16 rather than 32 as the final argument. (See comments in
+those functions for the reason.)
+
+The SSB_CONTINUE return is useful for parenthesized groups in patterns such as
+(a*)b where the group provides some optional starting code units but scanning
+must continue at the outer level to find at least one mandatory code unit. At
+the outermost level, this function fails unless the result is SSB_DONE.

+Arguments:
+ re points to the compiled regex block
+ code points to an expression
+ utf TRUE if in UTF mode

+Returns: SSB_FAIL => Failed to find any starting code units

+1. Break at the start and end of text (pretty obviously).
+
+2. Do not break between a CR and LF; otherwise, break before and after
+ controls.
+
+3. Do not break Hangul syllable sequences, the rules for which are:
+
+ L may be followed by L, V, LV or LVT
+ LV or V may be followed by V or T
+ LVT or T may be followed by T
+
+4. Do not break before extending characters.

+putting all the names into a single, large string and then using offsets in the

+data are unlikely.
+
+July 2008: There is now a script called maint/GenerateUtt.py that can be used
+to generate this data automatically instead of maintaining it by hand.
+
+The script was updated in March 2009 to generate a new EBCDIC-compliant
+version. Like all other character and string literals that are compared against
+the regular expression pattern, we must use STR_ macros instead of literal
+strings to make sure that UTF-8 support works on EBCDIC platforms. */

+/*************************************************
+* PCRE2 DEMONSTRATION PROGRAM *
+*************************************************/
+
+/* This is a demonstration program to illustrate a straightforward way of
+calling the PCRE2 regular expression library from a C program. See the
+pcre2sample documentation for a short discussion ("man pcre2sample" if you have
+the PCRE2 man pages installed). PCRE2 is a revised API for the library, and is
+incompatible with the original PCRE API.
+
+There are actually three libraries, each supporting a different code unit
+width. This demonstration program uses the 8-bit library.
+
+In Unix-like environments, if PCRE2 is installed in your standard system
+libraries, you should be able to compile this program using this command:
+
+gcc -Wall pcre2demo.c -lpcre2-8 -o pcre2demo
+
+If PCRE2 is not installed in a standard place, it is likely to be installed
+with support for the pkg-config mechanism. If you have pkg-config, you can
+compile this program using this command:
+
+gcc -Wall pcre2demo.c `pkg-config --cflags --libs libpcre2-8` -o pcre2demo
+
+If you do not have pkg-config, you may have to use this:
+
+gcc -Wall pcre2demo.c -I/usr/local/include -L/usr/local/lib \
+ -R/usr/local/lib -lpcre2-8 -o pcre2demo
+
+Replace "/usr/local/include" and "/usr/local/lib" with wherever the include and
+library files for PCRE2 are installed on your system. Only some operating
+systems (Solaris is one) use the -R option.
+
+Building under Windows:
+
+If you want to statically link this program against a non-dll .a file, you must
+define PCRE2_STATIC before including pcre2.h, so in this environment, uncomment
+the following line. */
+
+/* #define PCRE2_STATIC */

+* might think because of the possibility of matching an empty string. *
+* What happens is as follows: *
+* *
+* If the previous match was NOT for an empty string, we can just start *
+* the next match at the end of the previous one. *
+* *
+* If the previous match WAS for an empty string, we can't do that, as it *
+* would lead to an infinite loop. Instead, a call of pcre2_match() is *
+* made with the PCRE2_NOTEMPTY_ATSTART and PCRE2_ANCHORED flags set. The *
+* first of these tells PCRE2 that an empty string at the start of the *
+* subject is not a valid match; other possibilities must be tried. The *
+* second flag restricts PCRE2 to one match attempt at the initial string *
+* position. If this match succeeds, an alternative to the empty string *
+* match has been found, and we can print it and proceed round the loop, *
+* advancing by the length of whatever was found. If this match does not *
+* succeed, we still stay in the loop, advancing by just one character. *
+* In UTF-8 mode, which can be set by (*UTF) in the pattern, this may be *
+* more than one byte. *
+* *
+* However, there is a complication concerned with newlines. When the *
+* newline convention is such that CRLF is a valid newline, we must *
+* advance by two characters rather than one. The newline convention can *
+* be set in the regex by (*CR), etc.; if not, we must find the default. *

+ SLJIT_64BIT_ARCHITECTURE : 64 bit architecture
+ SLJIT_LITTLE_ENDIAN : little endian architecture
+ SLJIT_BIG_ENDIAN : big endian architecture
+ SLJIT_UNALIGNED : allows unaligned memory accesses for non-fpu operations (only!)
+ SLJIT_INDIRECT_CALL : see SLJIT_FUNC_OFFSET() for more information

+/*
+ This file contains a simple executable memory allocator
+
+ It is assumed, that executable code blocks are usually medium (or sometimes
+ large) memory blocks, and the allocator is not too frequently called (less
+ optimized than other allocators). Thus, using it as a generic allocator is
+ not suggested.
+
+ How does it work:
+ Memory is allocated in continuous memory areas called chunks by alloc_chunk()
+ Chunk format:
+ [ block ][ block ] ... [ block ][ block terminator ]
+
+ All blocks and the block terminator is started with block_header. The block
+ header contains the size of the previous and the next block. These sizes
+ can also contain special values.
+ Block size:
+ 0 - The block is a free_block, with a different size member.
+ 1 - The block is a block terminator.
+ n - The block is used at the moment, and the value contains its size.
+ Previous block size:
+ 0 - This is the first block of the memory chunk.
+ n - The size of the previous block.
+
+ Using these size values we can go forward or backward on the block chain.
+ The unused blocks are stored in a chain list pointed by free_blocks. This
+ list is useful if we need to find a suitable memory area when the allocator
+ is called.
+
+ When a block is freed, the new free block is connected to its adjacent free
+ blocks if possible.
+
+ [ free block ][ used block ][ free block ]
+ and "used block" is freed, the three blocks are connected together:
+ [ one big free block ]

+ ------------------------------------------------------------------------
+ Stack-Less JIT compiler for multiple architectures (x86, ARM, PowerPC)
+ ------------------------------------------------------------------------
+
+ Short description
+ Advantages:
+ - The execution can be continued from any LIR instruction. In other
+ words, it is possible to jump to any label from anywhere, even from
+ a code fragment, which is compiled later, if both compiled code
+ shares the same context. See sljit_emit_enter for more details
+ - Supports self modifying code: target of (conditional) jump and call
+ instructions and some constant values can be dynamically modified
+ during runtime
+ - although it is not suggested to do it frequently
+ - can be used for inline caching: save an important value once
+ in the instruction stream
+ - since this feature limits the optimization possibilities, a
+ special flag must be passed at compile time when these
+ instructions are emitted
+ - A fixed stack space can be allocated for local variables
+ - The compiler is thread-safe
+ - The compiler is highly configurable through preprocessor macros.
+ You can disable unneeded features (multithreading in single
+ threaded applications), and you can use your own system functions
+ (including memory allocators). See sljitConfig.h
+ Disadvantages:
+ - No automatic register allocation, and temporary results are
+ not stored on the stack. (hence the name comes)
+ In practice:
+ - This approach is very effective for interpreters
+ - One of the saved registers typically points to a stack interface
+ - It can jump to any exception handler anytime (even if it belongs
+ to another function)
+ - Hot paths can be modified during runtime reflecting the changes
+ of the fastest execution path of the dynamic language
+ - SLJIT supports complex memory addressing modes
+ - mainly position and context independent code (except some cases)
+
+ For valgrind users:
+ - pass --smc-check=all argument to valgrind, since JIT is a "self-modifying code"

+ Scratch (R) registers: registers whose may not preserve their values
+ across function calls.
+
+ Saved (S) registers: registers whose preserve their values across
+ function calls.
+
+ The scratch and saved register sets are overlap. The last scratch register
+ is the first saved register, the one before the last is the second saved
+ register, and so on.
+
+ If an architecture provides two scratch and three saved registers,
+ its scratch and saved register sets are the following:
+
+ R0 | [S4] | R0 and S4 represent the same physical register
+ R1 | [S3] | R1 and S3 represent the same physical register
+ [R2] | S2 | R2 and S2 represent the same physical register
+ [R3] | S1 | R3 and S1 represent the same physical register
+ [R4] | S0 | R4 and S0 represent the same physical register
+
+ Note: SLJIT_NUMBER_OF_SCRATCH_REGISTERS would be 2 and
+ SLJIT_NUMBER_OF_SAVED_REGISTERS would be 3 for this architecture.
+
+ Note: On all supported architectures SLJIT_NUMBER_OF_REGISTERS >= 10
+ and SLJIT_NUMBER_OF_SAVED_REGISTERS >= 5. However, 4 registers
+ are virtual on x86-32. See below.
+
+ The purpose of this definition is convenience. Although a register
+ is either scratch register or saved register, SLJIT allows accessing
+ them from the other set. For example, four registers can be used as
+ scratch registers and the fifth one as saved register on the architecture
+ above. Of course the last two scratch registers (R2 and R3) from this
+ four will be saved on the stack, because they are defined as saved
+ registers in the application binary interface. Still R2 and R3 can be
+ used for referencing to these registers instead of S2 and S1, which
+ makes easier to write platform independent code. Scratch registers
+ can be saved registers in a similar way, but these extra saved
+ registers will not be preserved across function calls! Hence the
+ application must save them on those platforms, where the number of
+ saved registers is too low. This can be done by copy them onto
+ the stack and restore them after a function call.
+
+ Note: To emphasize that registers assigned to R2-R4 are saved
+ registers, they are enclosed by square brackets. S3-S4
+ are marked in a similar way.
+
+ Note: sljit_emit_enter and sljit_set_context defines whether a register
+ is S or R register. E.g: when 3 scratches and 1 saved is mapped
+ by sljit_emit_enter, the allowed register set will be: R0-R2 and
+ S0. Although S2 is mapped to the same position as R2, it does not
+ available in the current configuration. Furthermore the R3 (S1)
+ register does not available as well.

+# There are two sorts of patterns in this test. A number of them are
+# representative patterns whose lengths and offsets are checked. This is just a
+# doublecheck test to ensure the sizes don't go horribly wrong when something
+# is changed. The operation of these patterns is checked in other tests.
+#
+# This file also contains tests whose output varies with code unit size and/or
+# link size. Unicode support is required for these tests. There are separate
