I had to deal with allot of regular expressions while programming SEOCpanel. As a result I wrote a quicky app that evaluates regular expressions.

This way I can test regular expressions before using them in my code.

RegEx is a small and very simple utility that tests regular expressions before using them. It will tell you if there is a match or not and the value of captures if any. It also includes a comprehensive cheat sheet. Very useful if you deal with regular expressions on a daily basis.
