Development Tool

Does anyone know what tool I can use to find all the duplicated code
in a class hierarchy? Lint? what rule?
Thanks in advance
Alejandro

It depends what you really means by duplication. If you mean the
bytecode are equals, you can use dynamic protocols for that (included
in all squeak-dev images). I can help you about that if you need to.

By duplication I meant:
  aParseTree equalTo: anotherParseTree exceptForVariables: #()
I don't know if this implies the same byte code on both methods, does it?

And about dynamic protocols...it shows me the duplicated methods
between a class and its super classes. What I'm looking for is
something that tells me what are the duplicated methods in a
collection of classes not necessarily related by hierarchy.

MethodFinder and MessageNames show all methods with equal names.
MethodFinder will also show results based on a pattern separated by full
stop:    1. 3. 4

I don't know about any tool about that but you can code it if you
want. Something like:

(yourClasses
     inject: Bag new
     into: [:bag :class | bag
                                  addAll: class methodDict values;
                                   yourself])
       valuesAndCounts

This gives you a dictionnary with compiled methods as keys and the
number of duplication of each method as values.
