Exercism

This is a nix shell for reproducible exercism in multiple languages. This is all the tooling you need:

• Nix
• direnv

Usage

Create or edit the .config/exercism/user.json file, and dump the following content

{
  "apibaseurl": "https://api.exercism.io/v1",
  "token": "<YOUR-API-TOKEN>",
  "workspace": "<PATH-TO-THIS-REPO>"
}

then you can proceed to do exercism in your favorite (supported) languages, adding support for more is easy.

$ cd erlang
direnv: loading ~/<YOUR_PATH>/.envrc
direnv: using flake .#erlang --impure
direnv: nix-direnv: Using cached dev shell
Starting Erlang environment...
# <...>
$ exercism download --track=erlang --exercise=difference-of-squares

Downloaded to
/<YOUR_PATH>/exercism/erlang/difference-of-squares

now just solve your exercise,

# <...>
$ cd difference-of-squares
