feat(ui): complete Phase 1 - debouncing, validation, callback registry
Phase 1 Complete - Convert UI Cleanup (dev23):
Debouncing (eliminates remaining sync flags):
- Add createDebouncedCallback() helper with 300ms delay
- Apply debouncing to CRF entry (updates: ~10/sec → ~3/sec)
- Apply debouncing to bitrate entry (eliminates syncingBitrate flag)
- Apply debouncing to target file size entry (eliminates syncingTargetSize flag)
- Remove all remaining sync boolean flags (syncingBitrate, syncingTargetSize)
Input Validation:
- Add validateCRF() - enforces 0-51 range
- Add validateBitrate() - checks positive numbers, warns on extremes
- Add validateFileSize() - checks positive numbers
- Apply validation to CRF, bitrate, and file size entries
- Provides immediate user feedback on invalid input
Callback Registry:
- Create callbackRegistry to replace nil checks
- Add registerCallback() and callCallback() with logging
- Use in setQuality() to eliminate 'if updateEncodingControls != nil'
- Foundation for eliminating 21+ nil checks (will expand in future)
Impact Summary:
- ALL sync flags eliminated: 5 → 0 (100% reduction!)
- Command preview updates while typing: ~10/sec → ~3/sec (70% reduction!)
- Input validation prevents invalid configurations
- Debouncing improves perceived responsiveness
- Callback registry provides better debugging (logs missing callbacks)
Files modified:
- internal/ui/components.go (SetSelectedSilent)
- main.go (debouncing, validation, callback registry)
Phase 1 COMPLETE! Ready for Phase 2 (ColoredSelect expansion & visual polish)
