Subject: [ruby-talk:14885] Re: ANTLR rules for Ruby

Hello Folks,

I worked plenty with YACC while I was a student, and learned how difficult
it is to debug, maintain, enhance, and optimize table-driven parsers.
Top-down, procedural parsers are completely the opposite. A top down parser
pays out in the short term even if it has to be written by hand.

I studied ANTLR once and it seemed pretty capable, but I haven't used it. I
have used JavaCC and found it exremely capable, but the tool is Java
specific. Anyway, ANTLR or not, I can't recommend a top-down parser enough.

How about a top-down parser written in Ruby? It would be a short, easy, and
fun experiment. If the performance is reasonable, then one can focus
attention on improving overal Ruby performance (which would also improve the
parser's).
