## 项目历史与用法

Jujutsu, invoked as `jj`, is a Git-compatible distributed version-control system that rethinks the user model around changes, automatic working-copy commits, an operation log, and undo. Its repository describes a storage abstraction that can use Git repositories as a backend while also drawing on ideas from Mercurial, Sapling, Darcs, and Google's Piper/CitC design.

### 项目历史

Martin von Zweigbergk says in the project README that he started Jujutsu as a hobby project in late 2019, and that it later became his full-time work at Google with help from other Googlers while remaining a community-supported open-source project. The README also records that the repository moved to the `jj-vcs` GitHub organization in December 2024.

The design grew around a few deliberately non-Git ideas: the working copy is represented as a commit, conflicts are first-class objects, operations are logged, and descendants are automatically rebased after rewrites. At the same time, the Git backend lets users keep GitHub and GitLab-oriented collaboration paths.

### 采用历史

Adoption has been driven by command-line developers who want Git interoperability without Git's index-centric workflow. The input package metadata records packaging across Homebrew, MacPorts, Nix, Scoop, and Winget, which is notable for a young VCS because it gives users a direct path on Unix-like and Windows systems.

The README notes that core developers use Jujutsu to develop Jujutsu on GitHub, turning the project into a self-hosting example for its own workflow.

### 使用方式

`jj` is used as a daily version-control CLI: users initialize or colocate repositories with Git, make changes that are automatically snapshotted, rewrite and split changes, inspect history with revsets/templates, push through Git remotes, and use the operation log to understand or undo repository operations.

The tool is especially interesting for stacked-change workflows because descendants are automatically rebased when earlier changes are edited, and conflicts can be carried as repository state instead of forcing immediate textual resolution.

### 为什么软件包爱好者会关心

For package nerds, `jj` is one of the rare modern VCS packages that is not merely a Git porcelain: it has its own data model while preserving Git-backed distribution. That makes the package a useful bellwether for how far a new developer tool can spread through standard package managers before a 1.0 line.

Its Rust implementation, Git compatibility, operation log, and self-hosting use make it a high-signal package in the developer-tools ecosystem.

### 时间线

- 2019: Martin von Zweigbergk starts Jujutsu as a hobby project.
- 2021: The README says Martin had used `jj` almost exclusively to develop the project itself since early January.
- 2023: Martin presents Google's plans for Jujutsu at Git Merge 2022, referenced by the README news section.
- 2024: Version 0.14 deprecates `jj checkout` and `jj merge`; version 0.24 adds `jj file annotate`; the repository moves to the `jj-vcs` organization.
- 2026: The changelog records 0.42.0 on 2026-06-04.

### Related projects

- The official README names Git, Mercurial, Sapling, Darcs, Breezy, and Piper/CitC as related systems or design influences. Its package neighborhood also includes `jjui`, a terminal UI built specifically for interacting with Jujutsu repositories.
