adding messages dinamically to a single instance object

Hi all. I need to know how can i do if i want add new behaviour ( a new method ) to a single instance object of a class.

It means not to add new selector to the class but i want a single instance responds that mesage.

Where can i read about it?

Re: adding messages dinamically to a single instance object

Hi.

Look at project Talents https://github.com/tesonep/pharo-talents.

Idea is to implement behaviour (also with state) in normal way with classes and then dynamically install it to any existing objects

Re: adding messages dinamically to a single instance object

Hi,

could you describe why you need this ? Do you have a usecase ?

Just interested to know, as i work on similar mechanisms.

Re: adding messages dinamically to a single instance object

Hi Steven . For the moment i just want to understand how it is possible.

In the future may be i can apply this mechanism for future projects.

Pablo I would not use talents.

You can use an anonymous classes.

Have a look at the chapter of

https://ci.inria.fr/pharo-contribution/view/Books/job/BuildingLanguageKernels/4/artifact/build/book.pdf

Thanks Denis, I will take a look . I think this is what i need.

It is really possible and we are working on a new implementation of talents based on anonymous classes.

Now what you should know is that

- i would use this mechanism for debugging/tooling

- i would try to avoid this as much as possible for domain modeling because

it breaks all the hidden assumptions we have.

Hola Pablo,

This technique is not something new, it was reported at least +20 years ago. You can read about it in a SO answer I wrote; http://stackoverflow.com/a/14202534 where there is a link to a foundational paper.

Let us know what are you trying to do.

Cheers,

Hernán
