Rubular is great. The only thing preventing it from being a 'one stop shop' for learning regular expressions is that it omits describing in the notes below some functionality (eg. the "?" shown in the example). http://rubyxp.com/ is better for these descriptions.
Rubular - a Ruby regular expression editor

Re: Rubular - a Ruby regular expression editor
#22I love rubular too. Question though... Why isn't it open source?
What would be gained if it were? I suppose you could run it locally. Come to think of it, that would be nice.
- Yes, run it locally. (Sometimes I want to test against sensitive information)
- Learn how a regex editor is built.
- Use a different regex engine (is that possible to swap)? [1]
I'm sure there are more reasons.

Re: Rubular - a Ruby regular expression editor
#23I also like using http://www.gskinner.com/RegExr/ Which I think is Flash/Flash Air... Being able to permalink (which Rubular also does) to examples is a killer feature..I keep trying to convince non-programmers who work with data that they should at least learn regexes to make their life easier

Flash uses Perl Compatible Regular Expression Engine (PCRE) http://www.pcre.org/
Ruby uses Oniguruma http://www.geocities.jp/kosako3/oniguruma/
While the average regex will probably work on both, you should know there isn't a 1:1 correlation between the two.

You aren't making it better.

It's not much more than a webapp wrapper around Ruby's built-in regex functionality.

as for [1] yes, you're just unable to use ruby's syntax.
Oniguruma (regex engine in ruby1.9) existed as an external library in the past (1.8) and you can get stuff like re2 for ruby this days[1]
