How can test I regular expressions using multiple RE engines?
regex, testing
Solution
The most powerful free online regexp testing tool is by far http://regex101.com/ - lets you select the RE engine (PCRE, JavaScript, Python), has a debugger, colorizes the matches, explains the regexp on the fly, can create permalinks to the regex playground.
Other online tools:
- http://regexpal.com/ - powered by the XRegExp JavaScript library
- http://www.rubular.com/ - Ruby-based
- Perl Regex Tutor - uses PCRE
Windows desktop tools:
- The Regex Coach - free Windows application
- RegexBuddy recommended by most, costs US$ 39.95
