emacs-pcre2el

Convert between PCRE, Emacs and rx regexp syntax

pcre2el or rxt (RegeXp Translator or RegeXp Tools) is a utility for working with regular expressions in Emacs, based on a recursive-descent parser for regexp syntax. In addition to converting (a subset of) PCRE syntax into its Emacs equivalent, it can do the following:

convert Emacs syntax to PCRE
convert either syntax to rx, an S-expression based regexp syntax
untangle complex regexps by showing the parse tree in rx form and highlighting the corresponding chunks of code
show the complete list of strings (productions) matching a regexp, provided the list is finite
provide live font-locking of regexp syntax (so far only for Elisp buffers – other modes on the TODO list).
