Determining what file contains a module/class

ruby-talk
1

Hi *,
I need to find the file that contains a known module or class, to
"inspect" the source code and extract what I need from the file.
Something like:

require 'digest'
Digest::base_file

'/usr/local/lib/ruby/1.8/digest.rb'

I already had some suggestions on IRC that involve scanning through all
the files in the path with a regexp, and in fact it solves my problem,
but I think it's a bit overcomplicated, so I'd like to know if there's
some other way that avoids all that scanning.

TIA,
  ngw

The problem in this case is that digest is specifically in digest.so,
not digest.rb. It also doesn't help if a module or class is defined
across multiple files, which is certainly permitted in Ruby.

For ruby-coded classes/modules only, Hugh Sasse's comprehensive RDOC of
every file/ class/method (builtins only, no Std. Lib):

(Also not sure which 1.8 snapshot this is)

Well, I've used digest just to make an example, my question was more
general :=)
Actually I'm using something like:

SCRIPT_LINES__ = {}
require 'net/ftp'
SCRIPT_LINES__.keys

that solves two problems in one.
