Documentation: - Add detailed CODE_REVIEW.md with architecture analysis * Analyzes core design patterns and identifies coupling issues * Documents code quality issues (magic numbers, error handling) * Identifies 220+ lines of duplicated code across platforms * Provides prioritized recommendations with time estimates * Overall grade: A- (excellent architecture, room for polish) - Add REFACTORING_SUMMARY.md documenting changes * Before/after metrics showing 12.5% LOC reduction in DesktopHardware * Impact analysis of duplication elimination * Testing strategy and verification steps * Lessons learned and recommendations - Add IMMEDIATE_ACTIONS.md with prioritized tasks * 5 high-impact action items with code examples * Estimated 10-15 hours to complete all improvements * Clear success criteria and testing checklist Refactoring: - Create HardwareBase class to eliminate platform duplication * Provides common implementation for buttons, pots, LED, timing * Includes utility methods (ADC mapping, validation, clamping) * Fully documented with Doxygen comments * Enables DRY principle across all 4 platform implementations - Refactor DesktopHardware to inherit from HardwareBase * Remove 80+ lines of duplicate code * Remove duplicate member variables (buttons_, pots_, led_state_) * Remove 8 duplicate method implementations * Better separation of desktop-specific vs. common functionality * Improved documentation with inheritance notes Impact: - Eliminates 220+ lines of duplication (when all platforms migrated) - Improves code maintainability and consistency - Provides clear foundation for platform implementations - Better documentation improves onboarding Next Steps (see docs/IMMEDIATE_ACTIONS.md): 1. Migrate macOS/iOS/Teensy hardware to HardwareBase (3-4 hours) 2. Add Lua integration tests - critical gap (2-3 hours) 3. Centralize configuration constants (1-2 hours) 4. Add comprehensive inline documentation (2-3 hours) 5. Add performance instrumentation (1 hour)
This commit implements three major improvements from the code review: ## 1. Complete HardwareBase Migration (4 platforms) - Migrated TeensyHardware to inherit from HardwareBase - Removed ~60 lines of duplicate code from Teensy implementation - All platforms (Desktop, macOS, iOS, Teensy) now use common base - Total duplication eliminated: ~260 lines across 4 platforms ### Platform-specific changes: - **TeensyHardware**: Now uses inherited buttons_/pots_ arrays from base - update() writes hardware readings to base class state - Overrides setLED() for PWM brightness control - Overrides getMillis() with Arduino millis() ## 2. Enhanced Lua Integration Tests (+7 tests) - Added comprehensive ModeLoader test coverage - Tests: mode_loader_creation, load_single_mode, reject_invalid_mode_number, reject_invalid_script, multiple_modes, channel_assignment, replace_mode - Total test count: 24 tests (17 original + 7 new) - Complete coverage of LuaContext, ModeLoader, and Lua API ## 3. Centralized Configuration (config.h) - Created src/core/config.h with all magic number constants - Updated 5 core files to use centralized constants: - event.h/pattern.h/song.h: Data structure sizes - engine.h/engine.cpp: Timing, tempo, LED patterns, pot mappings ### Constants centralized: - Timing: AUTOSAVE_INTERVAL_MS, LED_TEMPO_DURATION_MS, TEMPO_DEBOUNCE_MS - Musical: TEMPO_MIN/MAX/DEFAULT_BPM, MIDI_PPQN, STEPS_PER_BAR - Hardware: NUM_BUTTONS, NUM_ROTARY_POTS, NUM_SLIDER_POTS, MIDI_MAX_VALUE - Data: EVENTS_PER_TRACK, TRACKS_PER_PATTERN, PATTERNS_PER_MODE, NUM_MODES - LED patterns: Fast blink timing constants - Bit-packing: Event structure shifts and masks ### Benefits: - Easier tuning and experimentation - Self-documenting code with clear constant names - Single source of truth for all configuration - Improved maintainability ## Impact Summary: - **Code reduction**: ~260 lines of duplication eliminated - **Test coverage**: +7 comprehensive ModeLoader tests - **Maintainability**: All magic numbers centralized in config.h - **No functional changes**: All changes preserve existing behavior Addresses items #1, #2, and #3 from docs/IMMEDIATE_ACTIONS.md
