Injecting namespaces in functions in clojure

Question

Is it possible to inject namespaces in a function in Clojure?

I want my i/o to be outside from the program and only inject it. The problem i faced, that i tried to give a namespace and invoke it i get the error message:

 No name namespace: my

(ns mymain
  (:require [myio]))

...

(defn my-test [my]
  (my/showworld))

;(play_game)
(my-test myio)

Answer 1

The usual way to pass logic is through functions and not by namespace aliases:

(defn my-test [show-world]
  (show-world))

(require 'myio)
(my-test myio/show-world)
