Exercism.io is a learning platform that combining coding challenges and mentors who review and advise on your solutions. Each challenge comes with Leiningen project that includes code and unit tests, although Exercism itself does not run those tests.

Use the Exercism CLI tool to download the Leiningen project for each challenge and use your preferred development tools to create the solutions. When feedback is required or you wish to share a solution, submit the code using the Exercism CLI tool. If tests are changed as well as source code, both files should be submitted.

Clojure Track

All the challenges are groups into specific language tracks, including the Clojure track

Join the language track and select either mentored mode or practice mode.

In mentored mode your solutions are added to the mentors dashboard for review from any of the available mentors. In practice mode you can complete as many solutions as you wish without waiting for a mentor.

Getting Started: Exercism CLI tool

Select an exercise and follow the Get started guide to download and install the exercism tool. This tool will download the project code and submit solutions back to the Exercism web site.

Use the Exercism tool to download a Leiningen project for the exercise

exercism download --exercise=exercise-name --track=clojure

Open the project in your preferred Clojure editor and write a solution to solve the tests in the exercise. Run the tests using Leiningen in the command line, using lein test or the test runner in your editor.

Once the tests pass and you are happy with the solution, submit it to the Exercism website

exercism submit /path/to/src-file

Using Clojure CLI tools

With Clojure CLI tools installed, then simply add a deps.edn file to the root directory of the Leiningen project downloaded by the Exercism CLI tool.

The deps.edn should contain the :paths for the src directory (and test if your test runner requires that path, e.g. cider test runner).

{:paths ["src"]}

To run tests, use an alias such as :test/runner from practicalli/clojure-deps-edn, an alias from your own ~/.clojure/deps.edn or add an alias directly to the project deps.edn file just created.

Support

The mentors on the Exercism website will provide a review of your submissions and you can switch between mentor and practice modes as you prefer.

practicalli/exercism-clojure-guides contains the design journal and solution to several Clojure exercises.

Ask for advice in the #exercism or #beginners channels of the Clojurians Slack community.
