ruby_parser version 2.3.0 has been released!
Published 2011-09-06 @ 16:25
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
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)))))
2.3.0 / 2011-09-06
2 minor enhancements:
- Add -g flag to parser compile if DEBUG
- Lexer now embeds line number in yacc_value for keywords, helping fix up line numbers
3 bug fixes:
- Fix method line numbers when no args and no parens (quix)
- Fixed line numbers on return/break/next w/ result expr. (pjnz)
- Fixed some lexing state in order to parse: ‘f (1), 2’ as ‘f(1, 2)’. (invernizzi)
