The classical introductory exercise. Just say "Hello, World!".
"Hello, World!" is the traditional first program for beginning programming in a new language or environment.
The objectives are simple:
If everything goes well, you will be ready to fetch your first real exercise.
You will find a test file named
Write your code in
src/hello_world.clj. It should use the namespace
hello-world so that tests can pick it up.
Run the tests using
lein test command and make them pass:
$ lein test lein test hello-world-test Ran 3 tests containing 3 assertions. 0 failures, 0 errors.
Then submit the exercise using:
$ exercism submit src/hello_world.clj
For more detailed instructions and learning resources refer exercism's clojure language page.
This is an exercise to introduce users to using Exercism http://en.wikipedia.org/wiki/%22Hello,_world!%22_program
It's possible to submit an incomplete solution so you can see how others have completed the exercise.
(ns hello-world-test (:require [clojure.test :refer [deftest is]] hello-world)) (deftest hello-world-test (is (= "Hello, World!" (hello-world/hello))))
(ns hello-world) (defn hello ( (hello "World")) ([name] (str "Hello, " name "!")))
A huge amount can be learnt from reading other people’s code. This is why we wanted to give exercism users the option of making their solutions public.
Here are some questions to help you reflect on this solution and learn the most from it.
