TLDR

A Rust library that reimplements Git from scratch, giving developers a fast and reliable way to add Git capabilities to their own applications without calling the git command.

Things people build with this

USE CASE 1

Build a Rust app that clones and fetches Git repositories without shelling out to the git command-line tool.

USE CASE 2

Read and write Git commits, references, and config files from within a Rust program.

USE CASE 3

Use as a Git backend in a Rust developer tool, similar to how Cargo uses it for package management.

USE CASE 4

Depend on only specific Git data model components like pack files or index files via modular crates.

In plain English

Gitoxide is a complete reimplementation of Git, the version control system used by most software projects worldwide, written entirely in Rust rather than C (which the original Git uses). The goal is to provide the same Git functionality with better correctness guarantees, faster performance, and cleaner programming interfaces for developers building tools on top of Git. The project is intended primarily as a library for other Rust programs to use, not as a drop-in replacement for the git command you run in your terminal. The main library, called gix, lets Rust developers add Git capabilities to their own applications without relying on calling the git command-line tool in the background. There are also two command-line tools for testing and development purposes, but the README explicitly notes these should not be relied on in scripts. In terms of what it can do today, gitoxide supports cloning repositories, fetching changes, checking file status, comparing file changes, reading and writing commits, browsing commit history, and reading and writing Git configuration files. Features still under development include pushing to remote repositories, merging commit histories, rebasing, and running commit hooks. The project tracks which features are complete versus planned in a separate status document. The codebase is split into dozens of smaller packages, each responsible for one piece of the Git data model: objects, references, configuration, index files, pack files, and so on. This modular structure means Rust developers can depend on just the parts they need. Gitoxide is open-source and under active development. It has been used as the Git backend in some Cargo (the Rust package manager) workflows. New users should check the project's crate status document to understand which operations are stable enough to build on before starting.

Copy-paste prompts

Prompt 1
Using the gix crate from gitoxide, write Rust code to clone a remote repository and print the latest commit message.
Prompt 2
Show me how to use gitoxide to check the status of changed files in a local Git repository, equivalent to running git status.
Prompt 3
How do I read a Git repository's configuration file using gitoxide in Rust? Show a working code example.
Prompt 4
Which Git operations are stable in gitoxide today and which are still experimental? I want to decide if it's safe for production use.
