How can test I regular expressions using multiple RE engines? [closed]

Answer 1

I use Expresso (www.ultrapico.com). It has a lot of nice features for the developer. The Regulator used to be my favorite, but it hasn't been updated in so long and I constantly ran into crashes with complicated RegExs.

Answer 2

Also this regex plugin can be useful for eclipse and idea users.

Answer 3

Answer 5

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://www.rexv.org/ - supports PHP and Perl PCRE, Posix, Python, JavaScript, and Node.js
• http://refiddle.com/ - Inspired by jsfiddle, but for regular expressions. Supports JavaScript, Ruby and .NET expressions.
• 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
