RegExRX is a regular expression editor with many features designed to help in the development and storage of regular expressions. Based on the PCRE library, RegExRX will allow a user to craft patterns that are compatible with most regular expression flavors and will let them easily copy those patterns to and from other languages like Perl, Ruby, PHP, Objective-C, JavaScript, AppleScript, 4D, and Xojo.

What's New

Version 1.8.1:
  • Otherwise-invisible characters will always be entered as their equivalent codes (like "xNN") in the pattern fields.
  • Optimized colorization of curly brackets.
  • Updated PCRE to 8.3.3.
  • Raised subgroup limit from 16 to 100.
  • Specifying too many subgroups in the search pattern will now report an error.
  • Copy As 4D Code (French) wasn't being more...

This application is excellent. Whether you use Regular Expression, or want to learn it, then you probably won't disappointed by what this has to offer. I've found it to be the most complete tool all around for Regex on OSX, and I think it's well worth the small price the developer is asking.

A great way to learn to use regular expressions - the program helps you to build your expression and then offers some great tools to debug it.
