CL-PPCRE - Portable Perl-compatible regular expressions for Common Lisp

CL-PPCRE is a portable regular expression library for Common Lisp which has the following features:

  • It is compatible with Perl.
  • It is pretty fast.
  • It is portable between ANSI-compliant Common Lisp implementations.
  • It is thread-safe.
  • In addition to specifying regular expressions as strings like in Perl you can also use S-expressions.
  • It comes with a BSD-style license so you can basically do with it whatever you want.
