Ruby_parser 1.0.0 Released

Ruby
1

ruby_parser version 1.0.0 has been released!

ruby_parser (RP) is a ruby parser written in pure ruby (utilizing
racc–which does by default use a C extension). RP’s output is
the same as ParseTree’s output: s-expressions using ruby’s arrays and
base types.

FEATURES/PROBLEMS:

  • Pure ruby, no compiles.
  • Incredibly simple interface.
  • Output is 100% equivalent to ParseTree.
    • Can utilize PT’s SexpProcessor and UnifiedRuby for language
      processing.
  • Known Issue: Speed sucks currently. 5500 tests currently run in 21
    min.
  • Known Issue: Code is waaay ugly. Port of a port. Not my fault. Will
    fix RSN.
  • Known Issue: I don’t currently support newline nodes.
  • Known Issue: Totally awesome.
  • Known Issue: dasgn_curr decls can be out of order from ParseTree’s.
  • TODO: Add comment nodes.

SYNOPSIS:

RubyParser.new.parse “1+1”

=> s(:call, s(:lit, 1), :+, s(:array, s(:lit, 1)))

Changes:

1.0.0 / 2007-12-20

I assume this doesn’t work with 1.9 [the racc, at least]?
Thanks!

Answering my own question [in 1.9 SVN HEAD]

As a note 1.9 does include racc still, as an extension, so I don’t think
this is expected.

Guess I’ll file it away to the core people.

I get a silent failure on 1.9.0-2, but it worked on 1.9.0-1. I’ll look
into it but would appreciate if you filed a bug.

Thanks for looking into that. I filed something but it was a little
obscure.
