Progress: hosts

What Works

Project Foundation

• ✅ uv project initialized: Basic Python 3.13 project with uv configuration
• ✅ Code quality setup: ruff configured for linting and formatting
• ✅ Memory bank complete: All core documentation files created and populated
• ✅ Architecture defined: Clear layered architecture and design patterns established

Documentation

• ✅ Project brief: Comprehensive project definition and requirements
• ✅ Product context: User experience goals and problem definition
• ✅ Technical context: Technology stack and development setup
• ✅ System patterns: Architecture, design patterns, and implementation paths
• ✅ Active context: Current work focus and next steps

What's Left to Build

Phase 1: Foundation (Immediate)

• ❌ Project structure: Create proper src/hosts/ package structure
• ❌ Dependencies: Add textual, pytest, and other required packages
• ❌ Entry point: Configure proper application entry point in pyproject.toml
• ❌ Core models: Implement HostEntry and HostsFile data classes
• ❌ Hosts parser: Create parser for reading/writing /etc/hosts files

Phase 2: Core Functionality

• ❌ Basic TUI: Implement main application with two-pane layout
• ❌ File loading: Read and parse existing hosts file
• ❌ Entry display: Show hosts entries in left pane
• ❌ Detail view: Show selected entry details in right pane
• ❌ Navigation: Keyboard navigation between entries

Phase 3: Read-Only Features

• ❌ Entry selection: Highlight and select entries
• ❌ Sorting: Sort entries by IP, hostname, or comments
• ❌ Filtering: Filter entries by active/inactive status
• ❌ Search: Find entries by hostname or IP

Phase 4: Edit Mode

• ❌ Permission management: Sudo request and management
• ❌ Edit mode toggle: Switch between read-only and edit modes
• ❌ Entry activation: Toggle entries active/inactive
• ❌ Entry reordering: Move entries up/down in the list
• ❌ Entry editing: Modify IP addresses, hostnames, comments

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
• ❌ Undo/Redo: Command pattern implementation
• ❌ File validation: Comprehensive validation before saving

Phase 6: Polish

• ❌ Error handling: Graceful error handling and user feedback
• ❌ Help system: In-app help and keyboard shortcuts
• ❌ Configuration: User preferences and settings
• ❌ Performance: Optimization for large hosts files

Current Status

Development Stage

Stage: Project Initialization Progress: 10% (Foundation documentation complete) Next Milestone: Basic project structure and dependencies

Immediate Blockers

1. Project structure: Need to create proper package layout
2. Dependencies: Must add textual framework to begin TUI development
3. Entry point: Configure uv to run the application properly

Recent Accomplishments

• Completed comprehensive project planning and documentation
• Established clear architecture and design patterns
• Created memory bank system for project continuity
• Defined development phases and priorities

Known Issues

Current Limitations

• Placeholder implementation: main.py only prints hello message
• Missing dependencies: Core frameworks not yet added
• No package structure: Files not organized in proper Python package
• No tests: Testing framework not yet configured

Technical Debt

• Temporary main.py: Needs to be moved to proper location
• Missing type hints: Will need comprehensive typing
• No error handling: Basic error handling patterns needed
• No logging: Logging system not yet implemented

Evolution of Project Decisions

Initial Decisions (Current)

• Python 3.13: Chosen for modern features and performance
• Textual: Selected for rich TUI capabilities
• uv: Adopted for fast package management
• ruff: Chosen for code quality and speed

Architecture Evolution

• Layered approach: Decided on clear separation of concerns
• Command pattern: Chosen for undo/redo functionality
• Immutable state: Selected for predictable state management
• Permission model: Explicit edit mode for safety

Design Considerations

• Safety first: Read-only default mode prioritized
• User experience: Keyboard-driven interface emphasized
• File integrity: Atomic operations and validation required
• Performance: Responsive UI for large files planned

Success Metrics Progress

Completed Metrics

• ✅ Project documentation: Comprehensive planning complete
• ✅ Architecture clarity: Clear technical direction established
• ✅ Development setup: Basic environment ready

Pending Metrics

• ❌ Functional prototype: Basic TUI not yet implemented
• ❌ File parsing: Hosts file reading not yet working
• ❌ User testing: No user interface to test yet
• ❌ Performance benchmarks: No code to benchmark yet

Next Session Priorities

1. Create project structure: Set up src/hosts/ package layout
2. Add dependencies: Install textual and pytest
3. Implement data models: Create HostEntry and HostsFile classes
4. Basic parser: Read and parse simple hosts file format
5. Minimal TUI: Create basic application shell

The project is well-planned and ready for implementation to begin.
