Subject: [ruby-talk:14881] Class/Module Information

It is possible to modify the following code to produce
the desired output rather than the actual output?

I (hope I) know things like instance variables do not
become "live" until the code is executed and some
of the methods cannot be stopped from including
superclass information. Just wondering if
anyone had any magical tricks :-)

I am trying to get all (most) of the information relating
(isolated) to a specific module or class.

Would anyting change for classes?

# Code Starts Here

module A
  CONSTANT_A = "A"
  @@class_a = nil
  def func_a
    @var_a = nil
  end
end

module B
  include A
  CONSTANT_B = "B"
  @@class_b = nil
  def func_b
    @var_b = nil
  end
end

module C
  include B
  CONSTANT_C = "C"
  @@class_c = nil
  def func_c
    @var_c = nil
  end
end

if __FILE__ == $0

  if false

    # Put test code here.
    # Change false to true for testing.

  else

    print "Name ................. "; p C.name
    print "Included Modules ..... "; p C.included_modules
    print "Constants ............ "; p C.constants
    print "Class Variables ...... "; p C.class_variables
    print "Instance Variables ... "; p C.instance_variables
    print "Instance Methods ..... "; p C.instance_methods

  end

end

# Code Ends Here

Actual Output:

Name ................. "C"
Included Modules ..... [B, A]
Constants ............ ["CONSTANT_C", "CONSTANT_B", "CONSTANT_A"]
Class Variables ...... ["@@class_c", "@@class_b", "@@class_a"]
Instance Variables ... []
Instance Methods ..... ["func_c"]

Desired Output:

Name ................. "C"
Included Modules ..... [B]
Constants ............ ["CONSTANT_C"]
Class Variables ...... ["@@class_c"]
Instance Variables ... ["@var_c"]
Instance Methods ..... ["func_c"]
