Hello Vitor,

Yeah, I was talking about that with Pablo (who implemented stateful traits) some times ago.

He told me that aliasing was he way to go.

There is no other option to override a trait method without aliasing it.

Cheers,

Julien

Well, found out about aliasing in http://pharo.gemtalksystems.com/book/LanguageAndLibraries/Traits/, is that the correct way of doint it?

Hello,

In a class that uses a Trait, how can I override one of it's method by appending behavior to the method implemented by the Trait? In a typical override, this is done by calling super:

method

   super method
   "extended behavior"
   ...

Is there a way to change "super" to a reference the Trait?

Hello Pablo,

Don't think it is ugly, I personally think it is wonderfull how those extensions to the language can be done with normal messaging passing code! But the information about this seems scattered a bit, I found in google and was not certain if the information was official or correct.

Also, there could be some default aliases in hand, in a way similar to groovy: http://docs.groovy-lang.org/latest/html/documentation/#_user_conflict_resolution

So, if I use TraitA with a methodX, this method could be aliased by default with something like TraitA_methodX. Don't know if this have some problem, just an idea (maybe I will explore this here :) )

regards,

Vitor

Hi Vitor, 

   as Julien correctly said there is no super call in traits. Currently the solution, maybe is a bit ugly, it is to use aliasing. 

Cheers,

Pablo
