Hop on over to CPAN and when you see something important/useful to you that doesn’t exist on RAA, there you go 🙂 andrew ---

[ [http://www.ruby-talk.org/cgi-bin/scat.rb/ruby/ruby-talk/177618](http://www.ruby-talk.org/cgi-bin/scat.rb/ruby/ruby-talk/177618) ] My port had some odd behaviour when running diff3 on a character-by-character basis, but I wasn’t able to confirm if it was a porting bug or a problem with the original algorithm. I stopped working on it when I discovered merge3, which seems to offer better merging logic anyway, but if anyone is interested in it, I could put it on rubyforge, I guess. -Adam
