It would be awesome if I can use this on my rails projects.

@ViriCruz Would supporting Ruby cover what you are looking for? (I am not aware of Rails-specific Regex aspects; let me know if I've overlooked anything.)

@xpe I'll answer that one - yes it would :)

More info on Ruby's regex here:

A Regexp holds a regular expression, used to match a pattern against strings. Regexps are created using the /.../ and %r{...} literals, and by the Regexp::new constructor.
