Hi all,
Is there any way to get method_added to work with class methods? (or to get the same functionality trough another means?)
Any pointers are appreciated.
class X
class << self
def method_added(*args)
p args
end
def singletin_method_added(*args)
p args
end
end
end
Don't ask me to explain it --it's mind numbing.

Hi --
class X
class << self
def method_added(*args)
p args
end
def singletin_method_added(*args)
s/tin/ton/ 
p args
end
end
end
I believe that only the singleton_method_added actually does anything.
I guess that's because the only methods you can add to this class are
singletons, and that gets priority.
At least, when I tried method_added, I couldn't get any output.

Like so many things, it comes down to:
* objects can have singleton methods
* singleton methods are stored in the object's singleton class
* classes are objects
It's so lovely, don't you think?

Thanks. That did the trick. I didn't know about singleton_method_added.

Indeed

Worksforme:
class Bar
class <<self; def method_added(m) p m end end
def x() end
end
:x
=> nil

So I just bought the pickaxe 2 and it's there. Gotta love this book.
I was surprised I didn't find it in ri, but now I see it there and it's a method of Object, not Module or Class. (which actually makes sense, when you think about it for a second)

Right -- actually the one that I expected would work, but didn't,
was a different one, and I got my wires crossed. Here it is:
class C
class << self
def self.method_added(m)
p m
end
def x
end
end

Well, but the question was about class methods, and you're defining an instance method.

That's what I'd been trying before I posted.
Can anyone explain why it doesn't work?
