co - AI-Powered Git Commit Message Generator

co is a command-line tool that uses OpenAI's GPT-4o to generate meaningful, well-formatted git commit messages based on your staged changes.

Features

• 🤖 Generates contextual commit messages based on your staged git changes
• 🔑 Securely manages your OpenAI API key
• ✏️ Interactive editor to review and modify suggested commit messages
• 📋 Supports multiple commit message formats:
  • Conventional Commits
  • Gitmoji (Unicode or shortcode format)
  • Simple format

Prerequisites

• Git installed and configured
• An OpenAI API key (with access to GPT-4o)

Installation

You'll need Go (Golang) installed so that you can run the following command to install co:

go install github.com/hamzabow/co@latest

Once installed, you can use co in any git repository. See the Usage section below for instructions.

Setup

You can provide your OpenAI API key in one of two ways:

1. Set the OPENAI_API_KEY environment variable:

   export OPENAI_API_KEY="your-api-key-here"

2. Enter it when prompted on first use. The tool will ask for your API key if not found in environment variables.

Usage

1. Stage your changes with git:

   git add .

2. Run the commit message generator:

   co

3. Review the generated message, edit if needed, and:

   • Press Ctrl+Enter to commit with the message
   • Press Ctrl+C to cancel

How It Works

1. The tool retrieves the diff of your staged changes using git diff --staged
2. It sends this diff to OpenAI's API with a carefully crafted prompt
3. The AI generates a commit message following the specified format
4. You get to review and edit the message before committing
5. After confirmation, the tool executes git commit -m "your message"

Configuration

The tool currently uses the Conventional Commits format by default. You can modify the format by editing the internal/genmessage/genmessage.go file to use one of the other prompt templates defined in internal/prompts/prompts.go.
