Newbie mixin question

Hi,
Just 2 questions:

  1. How can I mixin a class method (not an instance method)?

  2. How can I force a certain method to be called when the an object of a
    class that includes that module is initialized? Sort of like a mixin
    initialize…

TIA

Define initialize in the module, and call super from the class which
mixes it in.

module Foo
def foo
p “foo”
end
end

class Bar
Bar.extend(Foo)
end

Bar.foo

[matz:]

class Bar
Bar.extend(Foo)
end

Alternatively

class Bar
extend Foo
end
