regex
regex is a regular expression toolkit for regex-base with:
- text-replacement operations with named captures;
- special datatypes for matches and captures;
- compile-time checking of RE syntax;
- a unified means of controlling case-sensitivity and multi-line options;
- high-level AWK-like tools for building text processing apps;
- the option of using match operators with reduced polymorphism on the
text and/or result types;
- regular expression macros including:
- a number of useful RE macros;
- a test bench for testing and documenting new macro environments;
- built-in support for the TDFA and PCRE backends;
- comprehensive documentation and copious examples.
See the About page for details.
