Love this plugin! Makes life way easier than using online tools. It would be great if the plugin had an icon so it would match the rest of the tabs in my interface. Check out: https://github.com/mchaput/icons the author contributed it to font-awesome but it hasn't been used yet.

Thank you for a great plugin. I can't work without it. It makes debugging regex a pleasure. This is a must have plugin.

Excellent plugin for testing out Java-based RegExes. There are some sweet browser based tools out there, but every one that I've found uses the JavaScript RegEx engine which prevents certain functionality like lookbehind. Since this plugin uses Java's RegEx engine, I can test using all of the RegEx functionality available to me at runtime. Awesome! Thank you very much for building this wonderful plugin!

To testing JavaScript regex you can use online version http://myregexp.com/jsRegexp.html JS regex tester is in development so functionality is limited.

This is a fantastic plugin, but sadly it is not compatible with IDEA9! Do you plan to release an updated version.

Hi guys
I am using this plugin, but there is one "trouble": if regular expression consists much '*' or + as example (((A)*+*)*()*()+ then application (IDEA) hang down (freeze) :(

And another thing:
I suggest add check field for "auto match" - this is good when edit regexp (less stress for app/aplet) and also there will be great if regexp match proccess in separate thread and there is button to prevent it (stop match thread) for avoid my situation.

Thanks :)

P.S.
My regexp witch cause trouble:
\G((?:"(?:\\.|[^\\"])*+")|(?://.*+(?:\p{Space}|\z))|(?:/\*(?:[^\*]|\*(?!/))*+\*/)|(?:[^/"]|/(?!\*)(?!/))++)*?@Persist(?:(?:"(?:\\.|[^\\"])*+")|(?://.*+(?:\p{Space}|\z))|(?:/\*(?:[^\*]|\*(?!/))*+\*/)|(?:[^/"]|/(?!\*)(?!/))++)*?\p{Space}+([\w\$]+)(\p{Space}*=\p{Space}*(?s:.+?)\p{Space}*);

But if before ")*?@Persist" put "+" instead "++" then aplication (or applet) will be freeze.

P.P.S.
Sorry for my bad english :) I'll try do it better.
