Subject: Re: ruby global regex question.

I use this as an equivalent to global match:

class Regexp
  def global_match(str, &proc)
    retval = nil
    loop do
      res = str.sub(self) do |m|
        proc.call($~) # pass MatchData obj
        ''
      end
      break retval if res == str
      str = res
      retval ||= true
    end
  end
end

re = /.../
re.global_match(...) do |m|
    ...
end
