- **default_sort_reverse**: Default sort direction
- **backup_directory**: Location for automatic backups
## Architecture
The application follows a clean, layered architecture:
```
src/hosts/
├── main.py # Application entry point
├── core/ # Business logic layer
│ ├── models.py # Data models (HostEntry, HostsFile)
│ ├── parser.py # File parsing and writing
│ ├── manager.py # Edit operations and permissions
│ ├── config.py # Configuration management
│ ├── dns.py # DNS resolution (planned)
│ ├── commands.py # Command pattern for undo/redo
│ ├── filters.py # Entry filtering and search
│ └── import_export.py # Data import/export utilities
└── tui/ # User interface layer
├── app.py # Main TUI application
├── styles.py # Visual styling
├── keybindings.py # Keyboard shortcuts
└── *.py # Modal dialogs and components
```
### Key Components
- **HostEntry**: Immutable data class representing a single hosts entry
- **HostsFile**: Container managing collections of entries with operations
- **HostsParser**: File I/O operations with atomic writing and backup
- **HostsManager**: Edit mode operations with permission management
- **HostsManagerApp**: Main TUI application with Textual framework
## Development
### Setup Development Environment
```bash
# Clone and enter directory
git clone https://github.com/yourusername/hosts.git
cd hosts
# Install development dependencies
uv sync
# Run tests
uv run pytest
# Run linting
uv run ruff check
uv run ruff format
```
### Testing
The project maintains comprehensive test coverage with 150+ tests:
```bash
# Run all tests
uv run pytest
# Run specific test modules
uv run pytest tests/test_models.py
uv run pytest tests/test_parser.py
# Run with coverage
uv run pytest --cov=src/hosts
```
### Test Coverage
- **Models**: Data validation and serialization (27 tests)
- **Parser**: File operations and parsing (15 tests)
- **Manager**: Edit operations and permissions (38 tests)
- **Configuration**: Settings persistence (22 tests)
- **TUI Components**: User interface (28 tests)
- **Commands**: Undo/redo system (43 tests)
- **Integration**: End-to-end workflows (additional tests)
### Code Quality
The project uses `ruff` for linting and formatting:
```bash
# Check code quality
uv run ruff check
# Format code
uv run ruff format
# Fix auto-fixable issues
uv run ruff check --fix
```
## Security Considerations
- **Sudo handling**: Secure elevation only when entering edit mode
- **File validation**: Comprehensive input validation and sanitization
- **Atomic operations**: Safe file writing to prevent corruption
- **Backup system**: Automatic backups before any modifications
- **Permission boundaries**: Clear separation between read and edit operations
## Troubleshooting
### Common Issues
**Permission denied when entering edit mode:**
```bash
# Ensure you can run sudo
sudo -v
# Check file permissions
ls -la /etc/hosts
```
**Configuration not saving:**
```bash
# Ensure config directory exists
mkdir -p ~/.config/hosts-manager
# Check directory permissions
ls -la ~/.config/
```
**Application won't start:**
```bash
# Check Python version
python3 --version
# Verify uv installation
uv --version
# Install dependencies
uv sync
```
