silly question

[Ferenc Engard]

Hi all,

Sorry that I am asking so trivial, maybe it is too late: can I somehow
mix in module functions into a module or a class? I.e.,

module X
def X.foo; puts "foo"; end
end

module Y
include X # what to write here?
def bar; foo(); end # want to call X.foo
end

Is it even make sense?

In fact, I used ncurses library with ruby 1.6.8, and there I could use
Ncurses methods like in the example above. With the new libs I cannot do
that. Maybe in the old library the Ncurses methods were module AND
instance methods...?

Thanks,
Ferenc

module X

You can do it in Ruby, and it makes a lot of sense. Refer to the
pickaxe for details
http://phrogz.net/ProgrammingRuby/tut_modules.html#mixins

That description deals with normal mixin functionality, using instance
methods. Here I want to use a module method in another module (or class)
without qualifying it.

X.foo isn't an instance method but a singleton method of X,
that is, it's defined for nothing but X. So you can never call
it without X.
