How to use the replace method in Clojure strings

Overview

In an instance were we want to replace a string with a different string, the replace method comes in handy.

What are strings in Clojure?

A string is a sequence of characters enclosed in double “ ” quotation marks. One of the methods used to work with strings is the string replace method.

What is the string replace method in Clojure strings?

The string replace is a method used in Clojure to replace a matching string with another string.

Syntax

(replace str match replacement)

Parameter

The string replace method accepts three (3) parameters:

  1. str: Represents the string containing the string to be replaced.
  2. match: The string to be replaced.
  3. replacement: The string replacing the match.

Return value

This method returns the string with the part in match replaced by the string in replacement.

Example

(ns clojure.examples.hello
   (:gen-class))
(defn example []
   (println (clojure.string/replace "People work on themselves" #"themselves"
      "project")))
(example)

Explanation

Line 3: We create a function called example.

Line 4: Inside the example function we use the replace method to return the string.

Note: Notice how we call the replace method using clojure.string/replace. We use the dot notation on Clojure since the string/replace is the core Clojure method. We then replace the string themselves with project because the string we want to replace has been inside of the main string.

Line 6: We simply call the example function we created.
