Create amazing commits in just seconds

Say farewell to boring commits with AI! 🤯�

Install CommitAI as a CLI Tool

CommitAI lets you automate meaningful commit messages effortlessly using the CLI with cmt. In just two seconds, your staged changes are committed with an AI-generated message.

Installation

1. Install CommitAI globally for use in any repository:

   npm install -g @mantisware/commit-ai

2. Obtain an API key from OpenAI or another supported LLM provider. Ensure your OpenAI account has an active payment method for API access.

3. Configure CommitAI with your API key:

   cmt config set CMT_API_KEY=<your_api_key>

   The API key is stored securely in ~/.commit-ai.

Usage

To generate a commit message for staged changes, run:

git add <files...>
cmt

Running git add is optional—cmt will automatically stage changes for you.

Running Locally with Ollama

You can also run CommitAI with a local model through Ollama:

• Install and start Ollama.
• Execute ollama run mistral (only once, to pull the model).
• In your project directory, configure CommitAI:

git add <files...>
cmt config set CMT_AI_PROVIDER='ollama' CMT_MODEL='llama3:8b'

By default, the model used is mistral.

If Ollama runs on another machine or within Docker with GPU support, update the API endpoint:

cmt config set CMT_API_URL='http://192.168.1.10:11434/api/chat'

Replace 192.168.1.10 with the appropriate endpoint.

Running with DeepSeek Locally with LM Studio

You can also run CommitAI with a local model through LM Studio:

• Install and start LM Studio.
• Add the DeepSeekCoder model to your project. current: deepseek-coder-v2-lite-instruct or for macos deepseek-coder-v2-lite-instruct-mlx
• In your ~/.commit-ai configure CommitAI:

cmt config set CMT_MODEL='deepseek-coder-v2-lite-instruct-mlx' CMT_API_URL='http://127.0.0.1:1234' CMT_AI_PROVIDER='deepseek'

Replace http://127.0.0.1:1234 with the appropriate endpoint provided by LM Studio.

Configuration Options

Local Repository Configuration

Add CommitAI configurations to a .env file in your repository:

CMT_AI_PROVIDER=<openai (default), anthropic, azure, ollama, gemini, flowise, mlx, deepseek>
CMT_API_KEY=<your OpenAI API token> # or another LLM provider API key
CMT_API_URL=<optional proxy path to OpenAI API>
CMT_TOKENS_MAX_INPUT=4096  # Maximum input tokens (default: 4096)
CMT_TOKENS_MAX_OUTPUT=500  # Maximum output tokens (default: 500)
CMT_DESCRIPTION=true  # Append a brief description of changes
CMT_EMOJI=true  # Enable GitMoji support
CMT_MODEL='gpt-4o'  # Set AI model (e.g., 'gpt-4o', 'gpt-3.5-turbo')
CMT_LANGUAGE='en'  # Language preference
CMT_MESSAGE_TEMPLATE_PLACEHOLDER='$msg'  # Message template placeholder
CMT_PROMPT_MODULE='conventional-commit'  # Use 'conventional-commit' or '@commitlint'
CMT_ONE_LINE_COMMIT=false  # Single-line commit messages

Global Configuration

Global settings are stored in ~/.commit-ai and configured with:

cmt config set CMT_MODEL=gpt-4o

Local settings take precedence over global configurations.

Enable Full GitMoji Support

By default, CommitAI limits GitMoji to 10 emojis (🐛✨📝🚀✅♻️⬆️🔧🌐💡) to optimize API usage. To enable full GitMoji support:

cmt --fgm

Ensure CMT_EMOJI is set to true.

Skip Commit Confirmation

To commit changes without requiring manual confirmation:

cmt --yes

Ignore Files from AI Processing

Prevent CommitAI from processing certain files by creating a .commit-aiignore file:

path/to/large-asset.zip
**/*.jpg

By default, CommitAI ignores files like *-lock.* and *.lock.

Set Up CommitAI as a Git Hook

CommitAI can integrate as a Git prepare-commit-msg hook for seamless commit message generation within your IDE.

To enable:

cmt hook set

To disable:

cmt hook unset

To use the hook:

git add <files...>
git commit

Use CommitAI in GitHub Actions (BETA) 🔥

CommitAI can enhance commit messages automatically when pushing to a remote repository.

1. Create .github/workflows/commit-ai.yml with:

name: 'CommitAI Action'

on:
  push:
    branches-ignore: [main, master, dev, development, release]

jobs:
  commit-ai:
    runs-on: ubuntu-latest
    permissions: write-all
    steps:
      - name: Set Up Node.js
        uses: actions/setup-node@v2
        with:
          node-version: '16'
      - uses: actions/checkout@v3
      - uses: MantisWare/commit-ai@github-action-v1.0.4
        with:
          GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
        env:
          CMT_API_KEY: ${{ secrets.CMT_API_KEY }}
          CMT_MODEL: gpt-4o
          CMT_LANGUAGE: en

Ensure the OpenAI API key is stored as a GitHub secret (CMT_API_KEY).

Payment Information

CommitAI uses OpenAI API, and you are responsible for associated costs. By default, it uses gpt-3.5-turbo, which should not exceed $0.10 per workday. Upgrading to gpt-4o improves quality but increases cost.
