class Main
@@classes = []
def Main.classes
@@classes
end
end
class Root
Main.classes << self
end
class A < Root
end
class B < Root
end
puts Main.classes.inspect
I’d like Main.classes == [Root, A, B], but currently it only is [Root].
I understand why, but was wondering if there was an elegant way to get
what I’d like to have.
I know in this example, I could simply add “Main.classes << self” to
each subclass, but, hey, that’s way too much repetition for the 21st
century.

def self.inherited(sub_class)
Main.classes << sub_class

I’d just define “inherited” in class Main and not Root.
In my example, the subclasses descend from Root, not Main.
Then I’d define the class collection in Root and not Main. My point was
simply to put both into the same class. If you put it into Root you can
even extend the scheme so that for sub classes “inherited” is
automatically defined, in order to make this work recursively.

Ah, interesting … I’ll have to look that over (my brain is away from
the problem right now). Thx!
