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 module MyModule

I know I could do like:

module MyModule
  class A
      ...
   end
   class B
      ...
   end
end

but is there a meta programming shortcut that could do the same so I could “import” all the existing classes ?

Thanks,
Luc

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
