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.
This app doesn’t use OgreKit. It uses Perl. Great for those who aren’t satisfied with other grep engines.
I just found a cool app for testing regular expressions. This is an open-source Cocoa app that works on PowerPC and Intel. Visualizing the matching result of regular expression I write makes this app a fairly handy tool for people like me, who are learning regular expressions.
This app also has got a cool icon. Go to the website and download your copy. The website is part of Google Code. I can’t find any screenshots and the developers’ blogs are both in “coming soon” state. MacUpdate has a screenshot.
