Contributing to mbake

June 22, 2025 ยท View on GitHub

We love your input! We want to make contributing to mbake as easy and transparent as possible, whether it's:

  • Reporting a bug
  • Discussing the current state of the code
  • Submitting a fix
  • Proposing new features
  • Becoming a maintainer

Development Process

We use GitHub to host code, to track issues and feature requests, as well as accept pull requests.

Pull Requests

  1. Fork the repo and create your branch from main
  2. If you've added code that should be tested, add tests
  3. If you've changed APIs, update the documentation
  4. Ensure the test suite passes
  5. Make sure your code lints
  6. Issue that pull request!

Development Setup

# Clone your fork
git clone https://github.com/ebodshojaei/bake.git
cd mbake

# Create virtual environment
python -m venv venv
source venv/bin/activate  # On Windows: venv\Scripts\activate

# Install in development mode
pip install -e ".[dev]"

# Install pre-commit hooks
pre-commit install

Running Tests

# Run all tests
pytest

# Run with coverage
pytest --cov=bake --cov-report=html

# Run specific test file
pytest tests/test_bake.py -v

# Run formatting tests
pytest tests/test_comprehensive.py -v

Code Style

We use several tools to maintain code quality:

# Format code
black bake tests

# Sort imports
ruff check --fix bake tests

# Type checking
mypy bake

# Run all quality checks
pre-commit run --all-files

Adding New Formatting Rules

  1. Create a new rule in bake/core/rules/
  2. Inherit from FormatterPlugin
  3. Implement the format method
  4. Add tests in tests/fixtures/
  5. Update documentation

Example:

from bake.plugins.base import FormatterPlugin, FormatResult

class MyRule(FormatterPlugin):
    def __init__(self):
        super().__init__("my_rule", priority=50)
    
    def format(self, lines: List[str], config: dict) -> FormatResult:
        # Your formatting logic
        return FormatResult(
            lines=modified_lines,
            changed=True,
            errors=[],
            warnings=[]
        )

Testing Your Changes

Always add tests for new functionality:

# Create test fixtures
mkdir tests/fixtures/my_feature
echo "input content" > tests/fixtures/my_feature/input.mk
echo "expected output" > tests/fixtures/my_feature/expected.mk

# Add test case
# Edit tests/test_comprehensive.py to include your test

    • Give sample code if you can
  • What you expected would happen

  • Notes (possibly including why you think this might be happening, or stuff you tried that didn't work)

Feature Requests

We welcome feature requests! Please open an issue with:

  • Clear description of the feature
  • Why it would be useful
  • Example use cases
  • Proposed implementation (if you have ideas)
