Ruby oriented JavaCC-like parser generator?

Ruby
1

I’m looking for a really solid parser generator where I can write my own
grammar like in JavaCC or Lex/Yacc to parse files in a custom built
language. The more portable and more efficient the better (two mutually
exclusive requirements? :slight_smile: ) Any suggestions?

Thanks,
Eric

Hey Eric,

Have you checked out ANTLR?

Racc (Racc) is similar to Yacc.
You can write a grammer like in Yacc, and you can write actions in Ruby
instead of C.

It generates a ruby class for a grammer. The generated class depends on
racc-runtime (written in C), but the runtime is in the Ruby’s standard
library.
So it is efficient and portable.

Unless things have changed radically, ANTLR’s Ruby support
is effectively non-functional.

most of us use racc (for better or worse)… aaron and I are
maintaining it now and aaron has taken on rexx, tho he’s released it
under a new name (currently forgetting, but prolly on his github).
