Regular expressions - Tools to assist the developer at heart.

I've been using regular expressions for a number of years in the workplace but am always keeping my eyes open for helpful tools (you can never have too many!). I recently picked up a Mac as a second system at home and stumbled upon a cool little utility. It's called RegExhibit. Screenshots speak louder than words, so take a look at the following:



What I found really useful with this tool was the immediate feedback as you typed your regular expressions. Another huge seller for me was the help files for this software, as it had a decently detailed collection all in one place (saving you the need to hunt down regex basics on the net).




And of course, this software is completely free, so it's hard to complain :). For those of you Mac-less, another free web-based regular expression tool I typically turn to in the workplace is: http://www.regextester.com.
