Shortcut for nested modules

John Ky

Hello,

Is there a short cut for:

> module A; module B; module C; module D
> def D.f
> end
> end; end; end; end

The following doesn't work for me:

> module A::B::C::D
> def D.f
> end
> end

Thanks

That will work if A::B::C exist.

Hi Austin,

This code doesn't work either:

> module A; module B; module C
> end; end; end
>
> module A::B::C::D
> def D.f
> end
> end

testns.rb:5: uninitialized constant A::B::C::D::D (NameError)

Thanks

It's the presence of D in the method name that's the problem; any of
these will work:

module A::B::C::D
def self.f
puts 'foo'
end
end

module A::B::C::D
def f
puts 'foo'
end
module_function :f
end

module A::B::C::D
def f
puts 'foo'
end
extend self
end

Paul.
