The Regex Coach description
A graphical application which can be used to experiment with (Perl-compatible) regular expressions interactiv

The Regex Coach is a graphical application for Linux and Windows which can be used to experiment with (Perl-compatible) regular expressions interactively.

The Regex Coach is a tool that allows you to see whether a regular expression matches a particular target string.

Here are some key features of "The Regex Coach":

· 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.
