How to deprecate a Class?

Hi all,
In the issue tracker, there are many issues to deprecate several classes. so, What do you do in order to deprecate a class?
Could you explain the procedure to deprecate a class?

Thanks.

Re: How to deprecate a Class?

This is not easy. So far I saw several things:

1) move the class to a package Deprecated12 or Deprecated13 or whatever pharo version.
2) Nuke the class: empty the method dictionary. That way, you can load code that use such class but you will have lots of dnu at runtime

I am not sure which is the desired behavior now. Of course, a correct way to deprecate classes would be awesome, but I guess it is not that easy.

often it's just moving it to the Deprecated package. (Deprecated14, does not exist yet I think). Sometimes it makes sense
to deprecate the class instatiaton methods in addition.

The most important aspects is that there is not reference to it.
and that if we replace it by something else, it works.
After we can write in the comments in big that the class is deprecated.

Could you (we) also deprecate all the methods in the class? Ideally
in some automated way, of course.

Or remove all methods and implement

doesNotUnderstand:

^Error new signal: 'All mehtods of this class are deprecated, please use ....'

Re: How to deprecate a Class?

Why not make this class a factory in the interim ?

DeprecatedClass class>>new
self deprecated: 'DeprecatedClass use BrandNewClass instead'.
^BrandNewClass new

Re: How to deprecate a Class?

I'd rather use trait.
Note that in both cases, subclasses will be made deprecated too.
