feat: zcatgui v0.14.0 - Phase 8 Accessibility & Testing
...
Accessibility System:
- Role enum for all widget types (button, checkbox, slider,
tree, table, menu, dialog, etc.)
- State packed struct (disabled, focused, selected, checked,
expanded, pressed, invalid, readonly, required, busy)
- Info struct with label, description, value, position,
level, controls, labelled_by
- Manager for tracking widget accessibility info
- announce() method for screen reader announcements
- Live region support (polite, assertive)
- Helper constructors for common patterns
Testing Framework:
- TestRunner for simulating user interactions:
- Mouse: click, doubleClick, drag, scroll, moveMouse
- Keyboard: pressKey, typeText, shortcut
- Time: tick, waitFrames, advanceTime
- SnapshotTester for visual regression testing:
- capture() to save framebuffer
- compare() to diff against baseline
- update() to update baseline
- Assertions module:
- assertVisible, assertContains, assertIntersects
- assertColorEqual, assertColorNear
- assertInRange
Widget count: 35 widgets
Test count: 274 tests passing

feat: zcatgui v0.6.0 - Phase 1 Optimization Complete
...
Performance Infrastructure:
- FrameArena: O(1) per-frame allocator with automatic reset
- ObjectPool: Generic object pool for frequently allocated types
- CommandPool: Specialized pool for draw commands
- RingBuffer: Circular buffer for streaming data
- ScopedArena: RAII pattern for temporary allocations
Dirty Rectangle System:
- Context now tracks dirty regions for partial redraws
- Automatic rect merging to reduce overdraw
- invalidateRect(), needsRedraw(), getDirtyRects() API
- Falls back to full redraw when > 32 dirty rects
Benchmark Suite:
- Timer: High-resolution timing
- Benchmark: Stats collection (avg, min, max, stddev, median)
- FrameTimer: FPS and frame time tracking
- AllocationTracker: Memory usage monitoring
- Pre-built benchmarks for arena, pool, and commands
Context Improvements:
- Integrated FrameArena for zero-allocation hot paths
- frameAllocator() for per-frame widget allocations
- FrameStats for performance monitoring
- Context.init() now returns error union (breaking change)
New Widgets (from previous session):
- Slider: Horizontal/vertical with customization
- ScrollArea: Scrollable content region
- Tabs: Tab container with keyboard navigation
- RadioButton: Radio button groups
- Menu: Dropdown menus (foundation)
Theme System Expansion:
- 5 built-in themes: dark, light, high_contrast, nord, dracula
- ThemeManager with runtime switching
- TTF font support via stb_truetype
Documentation:
- DEVELOPMENT_PLAN.md: 9-phase roadmap to DVUI/Gio parity
- Updated WIDGET_COMPARISON.md with detailed analysis
- Lego Panels architecture documented
Stats: 17 widgets, 123 tests, 5 themes
