RegExhibit is a program that allows you to interactively examine and test regular expressions.
It 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.
Version 1.2 improves responsiveness; RegExhibit no longer drops characters if you are a quick typer. It also fixes a bug that would cause a crash when entering text in multi-byte languages, like Japanese and Korean. Finally, RegExhibit now saves your preferences.
HERVé 5 I tried this app at its very beginning and posted here a worry about it not being universal. This is now solved for quite a long time, and the behavior is excellent.
I strongly appreciate the GUI, the enclosed help (including a short course on Regular Expressions...), the way the results are shown.
There are not many such "sandboxes" and this one is the best :-)
HERVé 5 on his site the dev does say it won't run native, on an intel mac you have to run it under Rosetta ('open with Rosetta')...
Other than this app you have RegExplor, http://www.macupdate.com/info.php/id/13271 which is also a Rosetta application, but starts spontaneously on Rosetta and works perfectly well. I use it daily. (Version 1.0)
