hook for class creation

Its Me

11/10/2004 6:58:00 PM

Is there a hook method called whenever a new class is created i.e.
guaranteed called for every new instance of Class ?

Class#initialize does not work.

Thanks.

You can try Object.inherited, but I'm not sure if it will get called
when a class is created internally in C code.

Plus it can be overridden in subclasses so there is no 100% guarantee of
it getting called.

Ah. Considering your suggestion I realized that I really wanted a hook for
just when my classes were created. So MyBase#inherited or MyMod#included are
good hooks.

Thanks!

p.s. the solution to my earlier question on clean-up for eval'ing named
class definitions in unit tests turned out to be
Module#remove_const

What about just putting the initialization code in the class definition?

class Foo
def bar
...
end
...
# class init
do_something
do_something_else
end

I think 213 wanted some automated mechanism, so you can't forget it when
you create a new class.

It must be hell to wake up one morning and realize that one hates a couple
or three billion people for no good reason at all.
Other than for the fact they are there.

Apparently Akins does not realize that his comments and his evidenced
prejudices are recorded here on the Net for ages to come.
When his great grandchildren decide to research the net to get a take on him
(and they will) there will be his ignorance and bigotry exposed for them to
see and realize
"Gramps was a nutter!!!!"

<shrug> More likely they'll simply say it's a common
enough name and deny any connection...after all, his
grandchildren are going to outlive him by a good bit
and they'll have plenty of time to break the nose off
his statue.
