prefligit is a reimplementation of the tool in Rust, designed to be a faster, dependency-free and drop-in alternative for pre-commit, while also providing some additional opinionated features.

Warning

This project is still in early stage of development, only a few of the original pre-commit features are implemented. It is not production-ready yet, but feel free to try it out and provide feedback.

Current supported languages are python, node, docker, docker-image, system, script and fail.

Note

This project was previously named pre-commit-rs, but it was renamed to prefligit to prevent confusion with the existing pre-commit tool. See #73 for more information.

Features

🚀 A single binary with no dependencies, does not require Python or any other runtime.
🔄 Fully compatible with the original pre-commit configurations and hooks.
⚡ Improved performance in hook preparation and execution.
🐍 Integration with uv for managing Python virtual environments and dependencies.
🛠️ Improved toolchain installations for Python, Node.js, Go, Rust and Ruby, shared between hooks.
📦 Built-in implementation of some common hooks.
🏗️ (TODO) Built-in support for monorepos.

Usage

$ prefligit run

cargo fmt................................................................Passed
cargo clippy.............................................................Passed

prefligit is designed to be a drop-in alternative for the original pre-commit tool, so you can use it with your existing configurations and hooks.

Please refer to the official documentation for more information on how to configure and use pre-commit.

Acknowledgements

This project is heavily inspired by the original pre-commit tool, and it wouldn't be possible without the hard work of the maintainers and contributors of that project.

And a special thanks to the Astral team for their remarkable projects, particularly uv, from which I've learned a lot on how to write efficient and idiomatic Rust code.
