elpa-pcre2el

Emacs mode to convert between PCRE, Emacs and rx regexp syntax

Description

This package provides `pcre2el' or `rxt' (RegeXp Translator or RegeXp Tools), 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).
