phg 2decad8047 Add unit tests for HostEntry and HostsFile models, and implement HostsParser tests
- Created comprehensive unit tests for HostEntry class, covering creation, validation, and conversion to/from hosts file lines.
- Developed unit tests for HostsFile class, including entry management, sorting, and retrieval of active/inactive entries.
- Implemented tests for HostsParser class, validating parsing and serialization of hosts files, handling comments, and file operations.
- Ensured coverage for edge cases such as empty files, invalid entries, and file permission checks.

  • File backup: Automatic backup before modifications

Phase 4: Advanced Edit Features

  • Add new entries: Create new host entries
  • Delete entries: Remove host entries
  • Bulk operations: Select and modify multiple entries
  • Validation: Real-time validation of IP addresses and hostnames
  • Undo/Redo: Command pattern implementation

Phase 5: Advanced Features

  • DNS resolution: Resolve hostnames to IP addresses
  • IP comparison: Compare stored vs resolved IPs
  • CNAME support: Store DNS names alongside IP addresses
  • Import/Export: Support for different file formats
  • Configuration: User preferences and settings

Phase 6: Polish

  • Error handling: Enhanced error handling and user feedback
  • Performance: Optimization for large hosts files
  • Accessibility: Screen reader support and keyboard accessibility
  • Documentation: User manual and installation guide

Current Status

Development Stage

Stage: Phase 1 Complete - Foundation Established Progress: 25% (Core functionality working) Next Milestone: Enhanced read-only features

Phase 1 Achievements

  1. Fully functional TUI: Application successfully loads and displays hosts file
  2. Robust parsing: Handles comments, inactive entries, IPv4/IPv6 addresses
  3. Clean architecture: Well-structured codebase with separation of concerns
  4. Comprehensive testing: 42 tests covering models and parser functionality
  5. Code quality: All linting and formatting checks passing

Immediate Next Steps

  1. Enhanced UI: Improve visual feedback and entry highlighting
  2. Sorting/Filtering: Add basic data manipulation features
  3. Help system: Implement proper help modal
  4. Status improvements: Better visual indicators for entry states

Recent Accomplishments

  • Successfully implemented complete Phase 1 foundation
  • Created robust data models with validation
  • Built comprehensive hosts file parser with comment preservation
  • Developed functional TUI application with two-pane layout
  • Established comprehensive testing framework
  • Achieved clean code quality standards

Technical Implementation Details

Core Components Working

  • HostEntry: Data class with IP/hostname validation, active/inactive state
  • HostsFile: Container with entry management, sorting, and search capabilities
  • HostsParser: File I/O with atomic writes, backup creation, permission checking
  • HostsManagerApp: Textual-based TUI with reactive state management

Test Coverage

  • Models: 27 tests covering all data model functionality
  • Parser: 15 tests covering file operations and edge cases
  • Coverage: All core functionality thoroughly tested

Code Quality

  • Linting: All ruff checks passing
  • Type hints: Comprehensive typing throughout codebase
  • Documentation: Detailed docstrings and comments
  • Error handling: Proper exception handling in core components

Known Issues

Current Limitations

  • Help system: Currently shows status message instead of modal
  • Entry highlighting: Basic selection without visual enhancement
  • No edit capabilities: Read-only mode only (by design for Phase 1)
  • No sorting/filtering: Basic display only

Technical Debt

  • Help modal: Need to implement proper screen for help
  • Visual polish: Entry highlighting and status indicators need improvement
  • Error messages: Could be more user-friendly
  • Performance: Not yet optimized for very large hosts files
