🕷 software releases

ruby_parser version 1.0.0 has been released!

Published 2007-12-22 @ 15:00

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.


  • 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.


  RubyParser.new.parse "1+1"
  # => s(:call, s(:lit, 1), :+, s(:array, s(:lit, 1)))
