## 项目历史与用法

git-when-merged is a Python Git extension that finds the merge commit that first brought a given commit into a branch.

### 项目历史

Michael Haggerty created the repository in February 2013. The README says the command was originally based on a Stack Overflow suggestion for finding the merge commit that included a specific commit.

The project grew around Git-history forensics. The 2016 releases added recursive merge tracing, log output, commit-only output, branch display, and describe-based options. A 2022 release added the packaging work needed for PyPI distribution.

### 采用历史

The README documents several installation paths: pipx from PyPI, a local virtual environment, cloning the repository onto PATH, and Homebrew for macOS users. Package-manager metadata also lists distribution through Homebrew, MacPorts, and Nix.

### 使用方式

Practitioners use git when-merged during code archaeology, release maintenance, and regression tracking. It walks first-parent history to answer when and why a commit entered a branch, with options to show logs, diffs, merge ranges, patterns, and configured reference groups.

### 为什么软件包爱好者会关心

The tool is a package-nerd favorite because it wraps a subtle Git graph question in a memorable subcommand, making first-parent merge analysis scriptable and repeatable.

### 时间线

- 2013: Repository created.
- 2016: v1.1 and v1.2 releases expanded merge-analysis options.
- 2022: v1.2.1 added PyPI release packaging.
