Regex Coach


What functions are offered by Regex Coach?



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