Regex Search on Arbitrary Sequences in Ruby
In working on Laser, an unreleased static analysis tool, I found need to do regex searching on arbitrary Arrays. This is the writeup, and this is the gem.

Hey, that’s pretty neat! First of all though, the link to your blog appears to be broken (asked me to sign in), but I read the article from the front page.
A while back I wanted to do something similar for doing static analysis in ruby, and came up with SexpPath which was used to do pattern matching against the S-Expressions that RubyParser output. You might find it interesting, for instance with the ruby specific DSL you could do
sexp / R?{ _class } / R?{ _method }to get all the classes and their methods out of a S-Expression.I actually did experiment with it in RubyScope. In the end though, it turns out that grep is faster.
Anyways, all that to say, this looks pretty neat. How stable is Ripper’s output though? A lot of things seemed to say ‘Experimental’ when I last looked at it, and it seems to be um… lightly documented.
