Exercism Pyret Track

Exercism exercises in Pyret.

Setup

If you're solving Exercism exercises offline, you'll need a recent copy of pyret-npm (0.0.27+). Currently, pyret-npm works on Linux and MacOS platforms although Windows users can run it via the WSL. However, you can also use Pyret's online IDE. In that case, you'll need to switch from the IDE's default essentials2021 namespace to the older starter2024 supported by pyret-npm.

Support

For support with Pyret in Exercism, please visit the Pyret subcategory on the official Exercism forum.

Coding Style

Please consult the official Pyret style guide.

Testing

To test the exercises, run ./bin/verify-exercises on a Linux or MacOS platform. This command will iterate over all exercises and check to see if their exemplar/example implementation passes all the tests.

Contributing Guide

Please see Exercism's contributing guide.

Here's the basic template for an <slug>-test.arr. Each check block corresponds to a single test case, and its label is reported to the student.

use context starter2024

include file("<slug>.arr")

check "foo returns 1":
  foo() is 1
end

check "bar returns 2":
  bar() is 2
end

Track linting

configlet is an Exercism-wide tool for working with tracks. You can download it by running:

./bin/fetch-configlet

Run its lint command to verify if all exercises have all the necessary files and if config files are correct:

$ ./bin/configlet lint

The lint command is under development.
Please re-run this command regularly to see if your track passes the latest linting rules.
