ruby_parser version 3.0.0.a3 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.
As an example:
def conditional1(arg1)
if arg1 == 0 then
return 1
end
return 0
end
becomes:
s(:defn, :conditional1,
s(:args, :arg1),
s(:scope,
s(:block,
s(:if,
s(:call, s(:lvar, :arg1), :==, s(:arglist, s(:lit, 0))),
s(:return, s(:lit, 1)),
nil),
s(:return, s(:lit, 0)))))
Changes:
### 3.0.0.a3 / 2012-07-03
* 1 major enhancement:
* OMG! Implemented all the 1.9 arg crap and I went from 500 lines of
structural diff to 32!
* 17 minor enhancements:
* 1.9: !(...) is now a method call. ugh
* 1.9: Added __ENCODING__ keyword (returns Unsupported atm).
* 1.9: Added support for "a.()" thingy. whatever you call it. Have I ever mentioned that ruby has too much syntax? I mean really...
* 1.9: Moved kRETURN/kBREAK/kNEXT from command_call to command
* 1.9: Removed when_args and refactored into args production.
* 1.9: Support for not/! being a call to #!. why matz? why?!?
* 1.9: Support for trailing comma support in opt call args.
* 1.9: Switched keyword support to deal with 1.8 vs 1.9 differences.
* 1.9: refactored and created command_asgn
* 1.9: removed case/else from primary
* 1.9: reworked mlhs and family. Now horrible things like 'a, *, c = f' work
* 1.9: reworked top level rules from program to expr. Lots of lame refactorings in mri.
* Moved 'a[]' from primary down to method_call
* Removed 'args trailer' production from assoc_list (eg {1, 2}).
* Removed 1.9 support for : as a terminator in do/then
* RubyParser no longer subclasses the 18 parser, so I had to change some consts around.
* Undeprecated RubyParser - but now it is a compound parser that tries 1.9 first.
* 3 bug fixes:
* 1.9: fixed bang method name.
* Fixed case/when/splat handling on both 1.8 and 1.9.
* Removed lambda_body production from lambda
