Add existing classes into a module

Question

I have some existing ruby classes in a app/classes folder:

class A
   ...
end

class B
   ...
end

I\'d like to group those classes in a mod

Answer 1

Use the const_missing hook. If the constant can't be found in the current module, try to resolve in the global namespace:

class A; end
class B; end

module M
    def self.const_missing(c)
        Object.const_get(c)
    end
end

M::A.new
M::B.new
