Subject: [ANN] ParseTree 3.0.2 Released


ParseTree version 3.0.2 has been released!

* <http://rubyforge.org/projects/parsetree/>
* <http://www.zenspider.com/ZSS/Products/ParseTree/>
* <ryand-ruby@zenspider.com>

ParseTree is a C extension (using RubyInline) that extracts the parse
tree for an entire class or a specific method and returns it as a
s-expression (aka sexp) using ruby's arrays, strings, symbols, and
integers.

As an example:

   def conditional1(arg1)
     if arg1 == 0 then
       return 1
     end
     return 0
   end

becomes:

   [:defn,
     :conditional1,
     [:scope,
      [:block,
       [:args, :arg1],
       [:if,
        [:call, [:lvar, :arg1], :==, [:array, [:lit, 0]]],
        [:return, [:lit, 1]],
        nil],
       [:return, [:lit, 0]]]]]

Changes:

### 3.0.2 / 2008-11-04

* 1 minor enhancement:

   * parse_tree_show now defaults to unified, added -U to UNunify  
output.

* 4 bug fixes:

   * UnifiedRuby#rewrite_defn kinda sorta deals with cfunc now. Stupid  
rails.
   * Fixed ambiguities in splatted nodes in a bunch of contexts.
   * Fixed 1 arg form of parse_tree_for_proc
   * KNOWN ISSUE: 0 arg form (||) of parse_tree_for_proc segfaults.
