The Regex Coach is a graphical application for Linux and Windows which can be used to experiment with (Perl-compatible) regular expressions interactively. The application contains the following features:
It shows whether a regular expression matches a particular target string
It can also show which parts of the target string correspond to captured register groups or to arbitrary parts of the regular expression
It can "walk" through the target string one match at a time
It can simulate Perl's split and s/// (substitution) operators
It tries to describe the regular expression in plain English
It can show a graphical representation of the regular expression's parse tree
It can single-step through the matching process as performed by the regex engine
Everything happens in "real time", i.e. as soon as you make a change somewhere in the application all other parts are instantly updated
"Excellent hidden gem."
Highly recommended for perl lovers.
I'm surprised why this is not very popular. I used this for years while programming in perl.
