RegExr Desktop is a tool for learning, editing, and testing regular expressions (RegEx or RegExp for short) on Mac OSX, Windows, and Linux.
For now, it is simply a desktop version of the online RegExr application, but I will update it with desktop specific functionality as time permits.
You can install it with the badge below. Or, if you already have the AIR 1.0 runtime installed, and know what you're doing, you can use the ".air" file located here.
Please post any problems, feature requests, or feedback in the comments on this page.
