# 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](http://about.regex.uk) for details.


## regex and regex-examples

The library and tutorial, tests and examples have been split across
two packages:

  * the `regex` package contains the regex library with the Posix TDFA
    back end
  * the `regex-with-pcre` library package contains the extra modules
    needed for the PCRE back end
  * the `regex-examples` package contains the tutorial, tests
    and example programs.
