| [section Appendix 2: Not Yet Implemented] |
| |
| The following features are planned for xpressive 2.X: |
| |
| * `syntax_option_type::collate` |
| * Collation sequences such as [^'''[.a.]'''] |
| * Equivalence classes like [^'''[=a=]'''] |
| * Control of nested results generation with `syntax_option_type::nosubs`, |
| and a `nosubs()` modifier for static xpressive. |
| |
| Here are some wish-list features. You or your company should |
| consider hiring me to implement them! |
| |
| * Optimized DFA back-end for simple, fast regexing. |
| * Different regex compiler front ends for basic, extended, awk, grep |
| and egrep regex syntax. |
| * Fine-grained control over the dynamic regex syntax |
| * Optional integration with ICU for full Unicode support. |
| * Improved localization support, possibly as a custom facet for `std::locale`. |
