git-commit-gen 0.1.1

A tool to generate conventional commit messages using Gemini API

Git Commit Gen

A command-line tool to automatically generate concise and informative commit messages following the Conventional Commits specification using the Google Gemini API.

Features

• Analyzes staged Git changes (modified, added, and deleted files).
• Generates commit messages based on file diffs and changes.
• Ensures messages adhere to Conventional Commits format (e.g., feat: add new feature).
• Falls back to standard git commit if generation fails.

Installation

Install the package via pip:

pip install git-commit-gen

Prerequisites

• Python 3.8 or higher
• Git installed and configured
• A Google Gemini API key (see Configuration)

Usage

Run the tool in a Git repository with staged changes:

git-commit-gen

You can pass additional Git commit options:

git-commit-gen --amend
git-commit-gen -v

The tool will:

1. Analyze your staged changes.
2. Generate a commit message using the Gemini API.
3. Warn if the message doesn't follow Conventional Commits.
4. Execute the commit with the generated message.

Configuration

The tool requires a Google Gemini API key. Set it in a .env file in your working directory or as an environment variable:

Using a .env file

Create a .env file in your project root:

GEMINI_API_KEY=your_api_key_here

Using environment variables

Set the key in your shell:

export GEMINI_API_KEY=your_api_key_here

Optional environment variables:

• GEMINI_MODEL: Specify the Gemini model (default: gemini-2.0-flash-001).
• MAX_DIFF_SIZE: Maximum diff size to include in the prompt (default: 2000).

Example

1. Stage some changes:

   git add .
   

2. Run the tool:

   git-commit-gen
   

3. Output might look like:

   feat: implement user authentication
   

If the generated message doesn't follow Conventional Commits:

Warning: Generated commit message may not follow Conventional Commits.
It is recommended to review and adjust the message before committing.
Proposed message: update readme file
