Looking for a parser generator

ruby-talk
1

Hi all,

I'm looking for a nice parser generator which given an EBNF grammar
can build an AST and Rockit seems a very good option. However, I keep
getting errors when trying to run the examples on Ruby 1.8. I've also
seen some other people complaining on the list because they run into
similar problems. Is this project dead? What other options can I
choose from?

Thanks,
Ed

racc: nice and simple, runtime included in default Ruby distribution
(...though not the generator itself).

Racc Grammar File Reference appears to have a
tutorial.

Download http://www.wingding.demon.nl/ -> Rpay2 for an example for
actual usage.

Depending on what you are after, the EBNF and attributes, one of
the Coco/R tools may be suitable. There are two, one pure Ruby and
the other for C extensions. Note that they are both LL(1) with
single token look-ahead, so that may, or may not, suit your
style.
