What is a good regular expression tester for OS X? [closed]

Question

I'm looking for a GUI based RegExp tester in the vein of rubular.com, or this JavaScript expression tester here, for OS X, to help me when writing regular expressions.

It would be really handy for it to work in more than one language (i.e. Python, JavaScript, or Ruby).

Other than using MacVim's own find as you type tool, or a command line editor like Vim or Emacs, (I use Textmate as my main editor), what are my options here?

give Reggy a try! ...simple and effective!

NOTE: Though the last 1.3 release of the app is quite old (2007), a new version written in Objective-c is under development on Github

Answer 2

Maybe you can just use one of the online RegExp testers, like "RegExr".
