prefligit 0.0.18

Better `pre-commit`, re-engineered in Rust

prefligit

pre-commit is a framework to run hooks written in many languages, and it manages the language toolchain and dependencies for running the hooks.

prefligit is a reimagined version of pre-commit, built in Rust. It is designed to be a faster, dependency-free and drop-in alternative for it, while also providing some additional long-requested 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.
• ⚡ About 10x faster and uses roughly 2/3 less disk space than pre-commit.
• 🔄 Fully compatible with the original pre-commit configurations and hooks.
• 🐍 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.

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.
