# Exercism Exercises

A collection of my solutions to exercises completed on the [Exercism](https://exercism.org) platform.

## About Exercism

Exercism is a free, open-source platform that offers code practice and mentorship across dozens of programming language tracks. Each track focuses on a specific programming language and provides a set of exercises ranging from beginner to advanced level. Exercises can be completed locally using the Exercism CLI and submitted for community or mentor feedback.

## Repository Structure

Exercises are organized by language track. Each track folder contains a `flake.nix` file that provides a Nix development shell with all the necessary tooling to work on exercises locally, along with one subdirectory per completed exercise.

Some files and folders such as `.exercism` and `HELP.md` are ignored because they are identical across every exercise and are not relevant to reading the solutions.

```

│   └── ...
├── php/
│   ├── flake.nix
│   ├── hello-world/
│   └── ...
```

## Development Environment

Each language folder contains a `flake.nix` that sets up a ready-to-use development shell via Nix. This ensures a reproducible environment without manually installing compilers, runtimes, or package managers on the host system.

To enter the development shell for a given track, run the following from inside the track folder:

```bash
nix develop
```

This requires [Nix](https://nixos.org/download) to be installed with flakes enabled.

## Purpose

This repository serves as a personal archive of progress made on the platform. It is not intended as a reference for official solutions and reflects my own learning process.

## Missing Exercises

Some exercises cannot be downloaded to be completed locally. All solutions, including those done directly on the platform, can be found on my profile: [cosmeak](https://exercism.org/profiles/cosmeak).
