Lrexlib provides bindings of five regular expression library APIs (POSIX_, PCRE_, GNU_, TRE_ and Oniguruma_) to Lua_ >= 5.1. The bindings for TRE and Oniguruma are not currently complete.

Lrexlib is copyright Reuben Thomas 2000-2020 and copyright Shmuel Zeigerman 2004-2020, and is released under the same license as Lua, the MIT_ license (otherwise known as the revised BSD license). There is no warranty.

Thanks to Thatcher Ulrich for bug and warning fixes, and to Nick Gammon for adding support for PCRE named subpatterns.

Lrexlib is installed with LuaRocks_, using the command::

luarocks install lrexlib-FLAVOUR

where FLAVOUR is one of PCRE2, POSIX, oniguruma, TRE, GNU

Note that the obsolete PCRE version 1 is also supported, as flavour PCRE.
