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)))
Changes:
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.
