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...
