ParseTree 1.3.2 Released

[Ryan Davis]

ParseTree version 1.3.2 has been released!

** 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:

+ 1 minor enhancement
+ Added total line to end of ABC metric report.
+ 1 bug fix
+ Updates for ruby 1.8.2 parse tree changes.

This looks VERY cool thanks for releasing!
Dunno where it is useful though!

I have one paper I've written with an example:

I also wrote a quick class visualizer in 150 lines of ruby. Combine the
two and you start to have some real tools.

This is sweet. This is exactly what is needed to implement a
duck-type-checking utility.
