I've been browsing the Pragmatic Programmer book and was taken by the
"learn something new" statement.
Since parsers have always been interesting to me, I decided on racc.
I put together a sample that I found on cmills.freesheel.org
presentation and have put a copy of it here:
Can any tell me why this doesn't work?
I'm using ruby 1.8.4 and racc version 1.4.5. Thanks for any guidance
you might provide.

Looks like I made a type on line 32 of the pastie. It reads:
when /\A\S+/o
and should be:
when /\A\s+/o
Yikes! 
Its surprising that there wasn't more conversation about this....is
there an elephant in the room that I can't see?
It seemed like everywhere I went to look for information about this, I
read "yacc/racc is hard".
If folks aren't using stuff like this, what do they use instead?

I looked at raac but the lack of docs put me off. Dhaka too much better in that respect and I am just about to start using it.

Dave,
Thanks for pointing me to that. The good thing about dhaka seems that
there are recent posts, implying active development.
I looked at racc because it seemed to be "the standard" with regard to
what folks would most likely be able to help with if I ran into
trouble.
I'll give dhaka a try too and see what I can make of it.
Hopefully you'll post some of your experiences here as well.
