| This section covers the regular expression syntax used by this library, this |
| is a programmers guide, the actual syntax presented to your program's users |
| will depend upon the flags used during expression compilation. |
| </p> |
| <p> |
| There are three main syntax options available, depending upon how you construct |
| the regular expression object: |
| </p> |
| <div class="itemizedlist"><ul type="disc"> |
| <li> |
| <a class="link" href="syntax/perl_syntax.html" title="Perl Regular Expression Syntax">Perl (this is the default |
| behavior)</a>. |
| </li> |
| <li> |
| <a class="link" href="syntax/basic_extended.html" title="POSIX Extended Regular Expression Syntax">POSIX extended (including |
| the egrep and awk variations)</a>. |
| </li> |
| <li> |
| <a class="link" href="syntax/basic_syntax.html" title="POSIX Basic Regular Expression Syntax">POSIX Basic (including |
| the grep and emacs variations)</a>. |
| </li> |
| </ul></div> |
| <p> |
| You can also construct a regular expression that treats every character as |
| a literal, but that's not really a "syntax"! |
