ruby_parser version 3.0.0 has been released!
Published 2012-11-02 @ 12:26
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.
As an example:
def conditional1 arg1 return 1 if arg1 == 0 return 0 end
s(:defn, :conditional1, s(:args, :arg1), s(:if, s(:call, s(:lvar, :arg1), :==, s(:lit, 0)), s(:return, s(:lit, 1)), nil), s(:return, s(:lit, 0)))
3.0.0 / 2012-11-02
I’ve hit 99.967% success rate against 558k files! 3.6σ!! 182 files failed to parse and spot checking them shows that they’re pretty much lost causes. I’m sure I missed some stuff, but it is more important at this point to release a version to get more people using it in more diverse ways than I can come up with.
3 minor enhancements:
- Added RBStringScanner#charpos using #string_to_pos.
- Added RBStringScanner#string_to_pos using String#byteslice.
- Optimized regexp used for escape chars in strings. (presidentbeef)
3 bug fixes:
- Fixed current_line and unread_many depending on StringScanner#pos
- Fixed parsing of ‘a = b’
- Fixed the worst abuse of heredocs EVER. Just because it is valid doesn’t mean you should.
