regex

regex is a regular expression toolkit for regex-base with:

• a text-replacement toolkit with type-safe text-replacement templates;
• 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 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 back ends;
• comprehensive documentation, tutorials and copious examples.

See the About page 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.
