Can’t seem to find much on this. The last post I could find dated back  
to 2006. I take it Ripper still can’t be used with 1.8.x?

Okay. That’s what is currently being used.

I was interested in Ripper’s scanner so I could do more fine grain  
analysis, e.g. count comments and blank lines.

If that’s all you need, you might try RubyLexer instead; it should  
allow you to count comments and blank lines pretty easily.

You might get some leverage with RACC, but I don’t know.
