Contributing to EXO
Thank you for your interest in contributing to EXO!
Getting Started
To run EXO from source:
git clone https://github.com/exo-explore/exo.git
cd exo
uv run exo
Development
EXO is built with a mix of Rust, Python, and TypeScript (Svelte for the dashboard), and the codebase is actively evolving. Before starting work:
- Pull the latest source to ensure you're working with the most recent code
- Keep your changes focused - implement one feature or fix per pull request
- Avoid combining unrelated changes, even if they seem small
This makes reviews faster and helps us maintain code quality as the project evolves.
Code Style
Write pure functions where possible. When adding new code, prefer Rust unless there's a good reason otherwise. Leverage the type systems available to you - Rust's type system, Python type hints, and TypeScript types. Comments should explain why you're doing something, not what the code does - especially for non-obvious decisions.
Run nix fmt to auto-format your code before submitting.
Testing
EXO relies heavily on manual testing at this point in the project, but this is evolving. Before submitting a change, test both before and after to demonstrate how your change improves behavior. Do the best you can with the hardware you have available - if you need help testing, ask and we'll do our best to assist. Add automated tests where possible - we're actively working to substantially improve our automated testing story.
Submitting Changes
- Fork the repository
- Create a feature branch (
git checkout -b feature/your-feature) - Commit your changes (
git commit -am 'Add some feature') - Push to the branch (
git push origin feature/your-feature) - Open a Pull Request and follow the PR template
Reporting Issues
If you find a bug or have a feature request, please open an issue on GitHub with:
- A clear description of the problem or feature
- Steps to reproduce (for bugs)
- Expected vs actual behavior
- Your environment (macOS version, hardware, etc.)
