Test Your XRegExps with JRX

Cüneyt Yılmaz's JRX is a cool JavaScript regex tester inspired by the RX tool of Komodo IDE. Cüneyt recently added my XRegExp library to his tester, so JRX is now a nice and easy way to test XRegExp's singleline and extended modes, as well as named capture and other XRegExp-provided syntax. Check it out!

As for XRegExp, it has recently been upgraded to v0.5.2, which resolved a corner-case bug involving XRegExp.matchRecursive. See the changelog for details.

I'll take this opportunity to highlight some of my other favorite online regex testers. I've actively looked for these kinds of apps over the years and have seen more than 50 of them. Odds are you'll find something new here.

Edit (2008-06-18): Updated the list with a couple that have come out very recently.

• RegexPal — My own JavaScript regex tester. It includes real-time regex syntax and match highlighting. Although RegexPal uses XRegExp to provide the singleline option, unlike JRX it uses JavaScript regex syntax without the XRegExp syntax extensions.
• regex — Simple name, simple interface. Great set of flavor support (JavaScript, Perl, Python, PCRE, POSIX ERE).
• Regexp Editor — Java regex tester with regex syntax highlighting.
• RegExr — ActionScript regex tester with regex syntax highlighting.
• reWork — JavaScript regex workbench.
• reAnimator — Fun app for visualizing regex FSAs.
• RegexMate — JavaScript regex console.
• The REWizard — IE only, but offers regex building tools and an interesting visualization.
• MyRegexTester — Includes code generation and plain-text explanations (via the YAPE::Regex::Explain Perl module).
• Regular Expression Analyzer — Real-time regex explanation tree that mostly emulates Java, JavaScript, and Perl flavors. Its regex parsing code is very readable.
• Nregex — .NET regex tester.
• Rubular — Ruby regex tester.

Have fun!
