Overview

Namespaces in Clojure are used to distinguish classes into separate logical parts. They are used when we have multiple imported classes in our code. The ns-name method is one of the methods used to work with namespaces.

The ns-name method

The ns-name method is used to find a namespace in the current code being executed. Unlike the find-ns, this method does not return an object, but returns a string.

Syntax

(ns-name nameof-namespace)
Syntax for the ns-name method

Parameter

This method takes the parameter, nameof-namespace, which represents the name of the namespace.

Return value

This method returns the namespace as a string, if it exists.

Example

(ns clojure.examples.example
(:gen-class))
(defn func []
(println (ns-name 'clojure.string)))
(func)
Example of the ns-name method

Explanation

  • Line 3: We define a function, func.
  • Line 4: We use the ns-name method and print the output. Notice that the output is a string containing the name of the namespace we passed to the ns-name method.
  • Line 5: We call the function, func.
