## 💻 Code Style
|
||||
|
||||
### Python Style Guide
|
||||
|
||||
We follow PEP 8 with some modifications:
|
||||
|
||||
- **Line Length**: 88 characters (Black default)
|
||||
- **Import Sorting**: Use isort with Black profile
|
||||
- **Type Hints**: Required for all public functions
|
||||
- **Docstrings**: Google style for all modules, classes, and functions
|
||||
|
||||
### Formatting Tools
|
||||
|
||||
```bash
|
||||
# Format code
|
||||
black src/ tests/
|
||||
|
||||
# Sort imports
|
||||
isort src/ tests/
|
||||
|
||||
# Lint code
|
||||
flake8 src/ tests/
|
||||
|
||||
# Type checking
|
||||
mypy src/
|
||||
```
|
||||
|
||||
### Pre-commit Hooks
|
||||
|
||||
Our pre-commit configuration automatically runs:
|
||||
- Black (code formatting)
|
||||
- isort (import sorting)
|
||||
- flake8 (linting)
|
||||
- mypy (type checking)
|
||||
- pytest (basic tests)
|
||||
|
||||
## 📚 Documentation
|
||||
|
||||
### Code Documentation
|
||||
|
||||
- **Docstrings**: All public functions, classes, and modules
|
||||
- **Type Hints**: All function parameters and return values
|
||||
- **Comments**: Explain complex logic and business rules
|
||||
- **README Updates**: Keep installation and usage instructions current
|
||||
|
||||
### Documentation Style
|
||||
|
||||
```python
|
||||
def generate_firmware(device_bdf: str, board_type: str) -> Path:
|
||||
"""Generate firmware for specified PCIe device.
|
||||
|
||||
Args:
|
||||
device_bdf: PCIe device Bus:Device.Function identifier
|
||||
board_type: Target FPGA board type (35t, 75t, 100t)
|
||||
|
||||
Returns:
|
||||
Path to generated firmware binary
|
||||
|
||||
Raises:
|
||||
DeviceNotFoundError: If specified device doesn't exist
|
||||
BuildError: If firmware generation fails
|
||||
|
||||
Example:
|
||||
>>> firmware_path = generate_firmware("0000:03:00.0", "75t")
|
||||
>>> print(f"Firmware generated: {firmware_path}")
|
||||
"""

```

### Version Management
|
||||
|
||||
We use semantic versioning (MAJOR.MINOR.PATCH):
|
||||
|
||||
- **MAJOR**: Breaking changes
|
||||
- **MINOR**: New features (backward compatible)
|
||||
- **PATCH**: Bug fixes (backward compatible)
|
||||
|
||||
### Release Steps
|
||||
|
||||
1. **Update Version**: Increment version in `src/__version__.py`
|
||||
2. **Update Changelog**: Add release notes to CHANGELOG.md
|
||||
3. **Create Release Branch**: `release/vX.Y.Z`
|
||||
4. **Final Testing**: Comprehensive testing of release candidate
|
||||
5. **Tag Release**: Create git tag with version
|
||||
6. **Build Distribution**: Create wheel and source distributions
|
||||
7. **Publish**: Upload to PyPI
|
||||
8. **GitHub Release**: Create GitHub release with notes
|
||||
|
||||
### Distribution
|
||||
|
||||
```bash
|
||||
# Build distributions
|
||||
python -m build
|
||||
|
||||
# Check distributions
|
||||
twine check dist/*
|
||||
