ParseTree 2.0.0Edit
The new version of ParseTree, ParseTree 2.0.0, was released on 1 August 2007.
Changes
- 2 major enhancements:
- Rewrite methods completely rewritten. Rewriters:
- are no longer recursive.
- are no longer required to empty the sexp coming in.
- are depth first, so rewriter gets passed everything already normalized.
- keep rewriting until type doesn’t change.
- are magical goodness.
- Added UnifiedRuby module to aid others in writing clean SexpProcessors:
- bmethod/dmethod/fbody unified with defn
- fcall/vcall unified with call
- resbody unified with itself (lots of different forms)
- 5 minor enhancements:
- Add #modules to Module.
- Add Sexp::for shortcut for Sexp.from_array ParseTree.translate(…).
- Add parens for :block nodes as appropriate. May be overzealous.
- Made add_to_parse_tree global for reuse by other C extensions.
- Made test_ruby2ruby MUCH more rigorous with circular testing.
- 6 bug fixes:
- Added $TESTING = true to pt_testcase.rb. OOPS!
- Fixed some circular bugs, mostly by hacking them out, wrt operator precidence.
- Fixed splat arg processing when arg has no name.
- Fixed trinary operator.
- Fixed BMETHOD with no arguments.
- Removed hacky "self." thing for defs at top level PT use.
