|
|
- **Technical constraints**: Permission model and file safety requirements established
|
|
- **Directory structure**: Planned layout for Go project organization
|
|
|
|
### ✅ Foundation Implementation (COMPLETED)
|
|

|
|
- **Directory structure**: ✅ Complete project structure (`cmd/`, `internal/`, `tests/`)
|
|
- **Core data models**: ✅ `internal/core/models.go` with HostEntry and HostsFile structs
|
|
- **Validation system**: ✅ IP address and hostname validation with RFC compliance
|
|
- **Test suite**: ✅ Comprehensive tests (44 test cases, 100% passing)
|
|
- **Demo application**: ✅ Working `cmd/hosts/main.go` demonstrating functionality
|
|
|
|
## What's Left to Build
|
|
|
|
### 🚧 Core Functionality (Phase 1 - Current Priority)
|
|
- [ ] **Hosts file parser**: Read and parse `/etc/hosts` file format
|
|
- [ ] Parse IP addresses, hostnames, comments
|
|
- [ ] Handle disabled entries (commented out)
|
|
- [ ] Preserve original formatting and comments
|
|
- [ ] **File operations**: Read hosts file with error handling
|
|
- [ ] **Round-trip parsing**: Parse → modify → write back with format preservation
|
|
|
|
### 🎨 Basic TUI (Phase 2)
|
|
- [ ] **Main Bubble Tea model**: Core application state and structure
|
|
- [ ] **Two-pane layout**: Left list + right detail view
|
|
- [ ] **Entry list display**: Show active status, IP, hostname columns
|
|
- [ ] **Entry selection**: Navigate and select entries with keyboard
|
|
- [ ] **View mode**: Safe browsing without modification capability
|
|
|
|
### 🔧 Edit Functionality (Phase 3)
|
|
- [ ] **Edit mode transition**: Explicit mode switching with visual indicators
|
|
- [ ] **Permission handling**: Request sudo access when entering edit mode
|
|
- [ ] **Entry modification**: Add, edit, delete, toggle active status
|
|
- [ ] **File writing**: Atomic updates with backup and rollback
|
|
- [ ] **Input validation**: Real-time validation of IP and hostname inputs
|
|
|
|
### 🌐 Advanced Features (Phase 4)
|
|
- [ ] **DNS resolution**: Background hostname to IP resolution
|
|
- [ ] **IP comparison**: Compare resolved vs current IP addresses
|
|
- [ ] **Entry reordering**: Manual drag/drop or move commands
|
|
- [ ] **Sorting options**: Sort by IP, hostname, or custom order
|
|
- [ ] **Search/filter**: Find entries quickly in large files
|
|
|
|
### 🧪 Testing & Quality (Ongoing)
|
|
- [ ] **Parser tests**: Round-trip parsing, edge cases, malformed files
|
|
- [ ] **Model tests**: Data validation, entry manipulation
|
|
- [ ] **TUI tests**: User interactions, state transitions
|
|
- [ ] **Integration tests**: Complete workflows, file operations
|
|
- [ ] **Permission tests**: sudo scenarios, graceful degradation
|
|
|
|
## Current Status
|
|
|
|
### Project Phase: **Foundation Complete → Core Functionality**
|
|
- **Completion**: ~25% (foundation and core models complete)
|
|
- **Active work**: Ready to implement hosts file parser (Phase 1)
|
|
- **Blockers**: None - solid foundation established
|
|
|
|
### Development Readiness
|
|
- ✅ **Architecture designed**: Clear technical approach documented
|
|
- ✅ **Requirements defined**: User experience and functionality specified
|
|
- ✅ **Technology selected**: Bubble Tea stack confirmed and installed
|
|
- ✅ **Testing strategy**: TDD approach implemented and proven
|
|
- ✅ **Project scaffolding**: Complete Go module with all dependencies
|
|
- ✅ **Development environment**: Fully functional with comprehensive tests
|
|
|
|
### Risk Assessment
|
|
- **Low risk**: Well-established technology stack (Go + Bubble Tea)
|
|
- **Medium risk**: Permission handling complexity (sudo integration)
|
|
- **Low risk**: File format parsing (well-defined `/etc/hosts` format)
|
|
- **Medium risk**: TUI responsiveness with large files
|
|
|
|
## Known Issues
|
|
|
|
### Technical Challenges
|
|
- **Permission elevation**: Need to handle sudo gracefully across platforms
|
|
- **File locking**: Prevent concurrent modifications to `/etc/hosts`
|
|
- **Large file performance**: Ensure responsiveness with large hosts files
|
|
- **Terminal compatibility**: Test across different terminal applications
|
|
|
|
### Implementation Decisions Needed
|
|
- **Configuration storage**: Where to store user preferences and settings
|
|
- **Backup strategy**: How many backups to keep and where to store them
|
|
- **DNS timeout handling**: How to handle slow or unresponsive DNS queries
|
|
- **Error recovery**: How to handle corrupted hosts files or write failures
|
|
|
|
## Evolution of Project Decisions
|
|
|
|
### Initial Scope
|
|
- Started with comprehensive feature set including DNS resolution
|
|
- Planned for cross-platform compatibility from day one
|
|
- Emphasized safety and validation throughout
|
|
|
|
### Refined Approach
|
|
- **TDD emphasis**: Write tests first to ensure reliability
|
|
- **Incremental development**: Build core functionality before advanced features
|
|
- **Safety first**: Default to read-only mode, explicit edit mode transition
|
|
- **User experience focus**: Two-pane interface for efficiency
|
|
|
|
### Technology Evolution
|
|
- **Framework choice**: Bubble Tea selected for maturity and documentation
|
|
- **Architecture pattern**: MVU pattern from Bubble Tea ecosystem
|
|
- **Testing approach**: Comprehensive coverage with mocked dependencies
|
|
- **Development workflow**: Standard Go tooling with additional quality tools
|
|
|
