ParseTree 1.3.4 Released

ParseTree version 1.3.4 has been released!

   http://www.zenspider.com/ZSS/Products/ParseTree/

** DESCRIPTION:

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]]]]]

** FEATURES/PROBLEMS:

+ Uses RubyInline, so it just drops in.
+ Includes SexpProcessor and CompositeSexpProcessor.
  + Allows you to write very clean filters.
+ Includes show.rb, which lets you quickly snoop code.
+ Includes abc.rb, which lets you get abc metrics on code.
  + abc metrics = numbers of assignments, branches, and calls.
  + whitespace independent metric for method complexity.
+ Only works on methods in classes/modules, not arbitrary code.
+ Does not work on the core classes, as they are not ruby (yet).

Changes:

+ 2 bug fixes
  + bug:1459: Cleaned up and corrected superclass naming code.
  + bug:1458: Fixed while to support post-conditional while/until nodes.

Hello Ryan,

thanks for your efforts with ParseTree. I was wondering if one could
implement a Lisp style macro system for Ruby using your library. What
do you think?

regards,
George Moschovitis

ps: I am really amazed at the latest developments in Ruby Land
(ParseTree, RubyInline, RubyToC, Yarv, etc...) Great time to be a Ruby
hacker :slight_smile:

Hrm. I don't have the ability to put the modified AST back into ruby... but you might be able to fake it using ruby2ruby and evaling back into the class... :confused:
