Having trouble getting your regular expressions just right? Not sure what they match and what they leave out? Tired of having to write test programs every time? RegExhibit can help.
RegExhibit shows you what your regular expressions match as you type on a sample text you provide. You can set the colour RegExhibit uses for this, and whether it should underline matches and captures. It also provides full details on successful matches.
As RegExhibit uses Perl to interpret your regular expressions, you get access to one of the most complete regular expression dialects around. RegExhibit will even allow you to use Perl code inside a regular expression.
