ParseTree 1.5.0 Released

ParseTree version 1.5.0 has been released!

• http://rubyforge.org/projects/parsetree/
• 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 parsetreeshow, which lets you quickly snoop code.
  • echo "1+1" | parsetreeshow -f for quick snippet output.
• Includes parsetreeabc, which lets you get abc metrics on code.
  • abc metrics = numbers of assignments, branches, and calls.
  • whitespace independent metric for method complexity.
• Includes parsetreedeps, which shows you basic class level dependencies.
• Only works on methods in classes/modules, not arbitrary code.

• Does not work on the core classes, as they are not ruby (yet).
