ruby_parser version 3.0.0.a9 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
return 1 if arg1 == 0
return 0
end
becomes:
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.a9 / 2012-10-22
Holy crap! I've hit a 99.92% success rate against 558k files! 492
failed parses to go. NOW is the time to start testing ruby_parser
against your code!
* 16 minor enhancements:
* 1.9 parser: Finished magic encoding and utf-8 bom support.
* 1.9: Added leading dot support eg "a\n.b".
* 1.9: Added partial handling for *arg and opt=val args in block args.
* 1.9: OMFG Encoding is the worst thing ever. Overhauled encoding support once again. It is much better at doing last ditch guessing of the encoding of the source file.
* 1.9: added String#grep for legacy support.
* Added Sexp#block_pass?
* Added ability to delete slow files when they timeout.
* Added block_dup_check and refactored grammar code to use it for block arg handling.
* Added in_lex_state?(*states) to clean up lexer code.
* Added tentative support for optional block args. THIS IS SUBJECT TO CHANGE!!
* Added toggleable debugging to StackState to make my life easier
* All untested uses have not moved but have been laced with poison.
* Finally got good tests for most forms of double-block arg errors.
* Moved all _known_ uses of SyntaxError to RubyParser::SyntaxError
* f_block_optarg now always returns a block node.
* ruby_parse_extract_error uses Find.find instead of globbing so dot files aren't missed.
* 12 bug fixes:
* 1.9: Completely ignore IndexError in unread_many because... you know... it sucks.
* 1.9: Fixed lex state after lexing ? in trinary.
* 1.9: Fixed lex state in some ternarys.
* 1.9: Fixed parsing of "1 ? b('') : 2\na d: 3"... ARE YOU NOT GLAD?!?!
* Fix Timeout differences between 1.8 and 1.9 
* Fixed emacs-style encodings to deal with no whitespace.
* Fixed error message for bad % codes. (whitequark)
* Fixed lexing of :a==>b vs :a===b vs :a==>b. P.S. Your space bar is broken. chump.
* Fixed lexing of rare numeric formats.
* Fixed magic comment encodings on DOS files ... 
* Fixed ruby_parse_extract_error to exit non-zero on errors.
* Removed Symbol#is_argument and switch usage to is_arg?
