gitmsg-ai

AI-generated Conventional Commit messages from your staged Git diff.

• 🎲 Interactive mode — generate 3 options, pick the best with --interactive
• 💾 Smart caching — re-running on the same diff is instant
• 📊 Amend support — regenerate message for last commit with --amend
• 🌍 Multi-language — --lang ru, --lang en, 16+ languages
• 🪝 Git hook — auto-generate on every git commit
• 🔌 Two providers — Ollama (local) or OpenAI (API)

Contributing
Pull requests are welcome. To set up your dev environment:

undefined
Clone and install in dev mode
git clone https://github.com/Weretik18/commit-msg-ai.git

cd commit-msg-ai

pip install -e ".[dev]"

Install pre-commit hooks (runs ruff, format, encoding checks before each commit)
pip install pre-commit

pre-commit install

Run all hooks against all files (sanity check)
pre-commit run --all-files

Run tests
pytest tests/ -v

Lint manually
ruff check commit_msg_ai/ tests/


The `pre-commit` hooks run automatically on every `git commit` and check:
- Code formatting (`ruff-format`)
- Linting (`ruff`)
- Trailing whitespace and missing newlines
- TOML/YAML syntax
- Line endings (forces LF)

CI runs the same checks, so passing pre-commit locally means CI will pass too.
