Regexecution is a reference for regular expressions (commonly used in *nix, Mac OS X, PHP, Perl and a lot more programming languages).
Available as an iPad app, allows full character searching and real-time testing.

As anyone involved into programming and Mac OS X scripting, we deal almost every day with regular expressions, those somehow cryptic and pretty concise language expressions that provide great help in getting text and number pattern out of messy data.
It’s common in Perl, *nix shell scripting (hence the Mac OS X), PHP, Python, Ruby and more, so you’d better get used to regexs!

Until now, the best online resources has been the like of Regular-expressions.info, but now we have a handy and powerful iPad app that’s both a reference guide and a testing tool: meet regexecution (the app with a dreadful AK-47 icon!).

We liked it so much we video-reviewed it, check below:

Right from Michael Saltsman, regexecution’s developer, website:

Regexecution makes creating and testing regular expressions easier. It is a tool that allows you to reference, build and test regular expressions. Regexecution gives you functionality such as copying to clipboard, inserting operations directly into your expression and emailing all of your expression and test data to any email address.

Nice work, Michael!
