JRX: real-time JavaScript RegExp evaluator

I released a beta of my regex tool earlier this week at http://regex.larsolavtorvik.com/ . It uses AJAX to give you feedback right away without having to submit the page.

My goal is to make it easy for you to test your regex patterns.

So far it supports PHP PCRE, PHP POSIX, Javascript and Perl. I plan to add more languages later.

Feel free to come with comments and suggestions on my blog at http://larsolavtorvik.com/ about bugs, improvments etc to make the tool better for all of us that uses regex regulary.

Online tool for designing and testing regular expressions:

It uses ajax and perl for evaluating the expressions.

I had always struggled with regular expressions until I read "Mastering Regular Expressions" by Jeffrey Friedl. He did a great job of making a really mundane subject very interesting and even humorous at times. I wholly recommend it.

I'd ++ Ninja's recommendation. He was able to teach me a thing or two about regex in an emergency situation based on something he recalled from that book.
