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]]]]]
