Regular Expression Tool In AIR
RegExr Desktop is a tool for learning, editing, and testing regular expressions on Mac OSX, Windows, and Linux. This Adobe AIR application is still considered as a simple editor but expect many more features to come. It originates from the online version created by gskinner.
