I've whipped up a quick little regular Cocoa app to prototype regular expression. (Maybe someone else has one, I just couldn't find it.) This is the 0.1 version and works pretty well. It is missing documentation, and other sorts of fun stuff, but it gets the job done, and it is fast. Check it out and let me know what you think.
