How to add a new source

1. Create yaml file with the name of your issue. Look at the example

   # source/array_fetch.yml
   level: easy # (elementary|easy|medium|hard)
   tags: [string, numbers]
   author:
     github_nickname: your_name
     web_page: "http://your.site"
   description: |
     This is description.
     The description can be multiline.
   multicode_checks:
     langs: [javascript, php] #[ruby, javascript, python, php]

   Example: array_fetch.yml

2. Create a .clj file in the test/battle_solutions folder, e.g. array_fetch_test.clj

• Write a test by defining a function (deftest test-asserts ()) Look at the example

  ; test/battle_solutions/array_fetch_test.clj
  (deftest test-asserts
    (let [arr [\a \b \c]]
    (assert-equal \b (fetch arr 1 \d))
    (assert-equal \d (fetch arr 5 \d))
    (assert-equal \c (fetch arr -1 \d))
    (assert-equal \d (fetch arr -5 \d))))

• Write a namespace with your issue name

  ; test/battle_solutions/array_fetch_test.clj
  (ns battle-solutions.array-fetch-test
    (:require [clojure.test :refer :all]
              [battle-asserts.test-helper :refer [assert-equal assert]]))

• Write a function to resolve your tests

  ; test/battle_solutions/array_fetch_test.clj
  (defn fetch
    [s index default]
    (let [positive-index (if (> index 0) index (+ (count s) index))]
      (nth s positive-index default)))

Example: array_fetch_test.clj

3. Run tests

lein test

If you want to run test for only one issue - use lein test + namespace

lein test battle-solutions.array-fetch-test

4. Run code format

make format
