Key Improvements Implemented + +### 1. **Single Responsibility & Modularity** +- Split monolithic file into focused modules +- Each service handles one concern +- Easier to navigate and maintain +- Reduced merge conflicts + +### 2. **Constants Management** +- All hardcoded paths moved to `constants.py` +- Template-based script generation +- Environment variable names centralized +- Default values defined in one place + +### 3. **Path Handling with `pathlib.Path`** +- Replaced `os.path.*` with `pathlib.Path` +- More declarative and robust path operations +- Built-in `.mkdir(parents=True, exist_ok=True)` +- Cross-platform compatibility + +### 4. **Enhanced Error Handling** +- Specific exception catching (`OSError`, `zipfile.BadZipFile`, `shutil.Error`) +- Granular error reporting +- Consistent error response structure +- Better logging of specific failure points + +### 5. **Type Safety with TypedDict** +- Defined response structures for all methods +- Consistent API contracts +- Better IDE support and documentation +- Runtime compatibility with `Dict[str, Any]` + +### 6. **DRY Principle Implementation** +- `_remove_if_exists()` helper for file removal +- `_atomic_write()` for safe file writing +- `_ensure_directories()` for directory creation +- Unified file destination mapping + +### 7. **Atomic File Operations** +- Safe script writing with temporary files +- Prevents corruption during writes +- Proper cleanup on failures +- Consistent file permissions + +### 8. **Logger Injection** +- Services accept optional logger parameter +- Defaults to `decky.logger` when None +- Enables unit testing with mock loggers +- Better separation of concerns + +### 9. **Robust Configuration Parsing** +- Regex-based parsing instead of string splitting +- Handles edge cases (extra spaces, comments) +- Template-based generation +- Roundtrip consistency testing + +### 10. **Comprehensive Testing Framework** +- Unit tests for each service +- Mock filesystem with `pyfakefs` +- Mock logger injection +- Roundtrip testing for configuration +- Environment variable mocking + +## ๐งช Testing + +### Running Tests +```bash +# Install test dependencies +pip install -r requirements-test.txt + +# Run all tests +pytest tests/ + +# Run with coverage +pytest tests/ --cov=lsfg_vk + +# Run specific test file +pytest tests/test_installation.py +``` + +### Test Coverage +- **Installation Service**: ZIP extraction, file copying, installation checking +- **Configuration Service**: Script parsing, generation, roundtrip testing +- **DLL Detection Service**: Environment variable priority, path checking +- **Mock Integration**: All services work with mock loggers for testing + +## ๐ Migration Guide + +### For Developers +The public API remains unchanged - all existing frontend code will continue to work: + +```python +# These calls remain identical +plugin.install_lsfg_vk() +plugin.check_lsfg_vk_installed() +plugin.uninstall_lsfg_vk() +plugin.get_lsfg_config() +plugin.update_lsfg_config(...) +plugin.check_lossless_scaling_dll() +``` + +### For Maintainers +1. **Adding new features**: Add to appropriate service module +2. **Constants**: Define in `constants.py` +3. **New response types**: Add to `types.py` +4. **Testing**: Add tests for new functionality +5. **Common functionality**: Add to `base_service.py` + +## ๐ Benefits Achieved + +1. **Maintainability**: Easier to find and modify specific functionality +2. **Testability**: Comprehensive unit test coverage +3. **Reliability**: Atomic operations and better error handling +4. **Documentation**: Clear type definitions and API contracts +5. **Extensibility**: Easy to add new services or features +6. **Code Quality**: Follows Python best practices and patterns + +## ๐ Future Improvements + +### Next Steps (Not Yet Implemented) +1. **Async/Sync Decision**: Evaluate if true async I/O is needed +2. **Configuration Schema**: JSON schema validation for config files +3. **Dependency Injection**: More sophisticated service container +4. **Integration Tests**: End-to-end testing with real files +5. **Performance Monitoring**: Metrics and logging for operations +6. **Error Recovery**: More sophisticated error handling and retry logic + +### Potential Extensions +- Plugin settings persistence +- Multiple DLL version support +- Automatic updates checking +- Performance profiling integration +- Steam integration improvements + +--- + +This refactoring maintains 100% backward compatibility while significantly improving code quality, maintainability, and testability. diff --git a/lsfg_vk/__init__.py b/lsfg_vk/__init__.py new file mode 100644 index 0000000..8343853 --- /dev/null +++ b/lsfg_vk/__init__.py @@ -0,0 +1,14 @@ +""" +lsfg-vk plugin package
