Breadcrumb Implementation Status
Phase 1: Module Skeleton ✅ COMPLETE
Date: 2025-11-11
Completed:
- ✅ Created
src/gui/breadcrumb_widget.f90module - ✅ Defined cached state variables (segment paths, names, hover state)
- ✅ Implemented
create_breadcrumb_widget()function - ✅ Added draw, motion, and click callback stubs
- ✅ Implemented path parsing in
update_breadcrumb_cache() - ✅ Basic color coding (green root, red active, gray inactive, dark gray hover)
- ✅ Hit-testing function
find_segment_at_position() - ✅ Navigation on click (calls
scan_directory())
Key Features:
- Caches path segments on main thread
- Draw function reads cached data (thread-safe)
- Hover optimization (only redraws on state change)
- Supports ~ abbreviation for home directory
- Handles root paths correctly
Lines of code: ~350 lines
Next: Phase 2 is actually already included in Phase 1! The path parsing is done. Move to Phase 3 for integration and testing.
Phase 2: Path Parsing ✅ COMPLETE (merged into Phase 1)
Already implemented in update_breadcrumb_cache():
- ✅ Splits path into segments
- ✅ Handles ~ abbreviation
- ✅ Extracts display names
- ✅ Stores full paths for navigation
Phase 3: Cairo Drawing ✅ COMPLETE (merged into Phase 1)
Already implemented in on_draw_breadcrumb():
- ✅ Renders segments with Pango
- ✅ Color coding based on state
- ✅ Hover effects
- ✅ Stores bounds for hit-testing
Phase 4: Mouse Interaction ✅ COMPLETE (merged into Phase 1)
Already implemented:
- ✅ Hit-testing in
find_segment_at_position() - ✅ Motion callback with optimization
- ✅ Click callback with navigation
Phase 5: Integration ✅ COMPLETE
Completed:
- ✅ Updated
meson.buildto include breadcrumb_widget.f90 - ✅ Replaced old breadcrumb in
gtk_app.f90 - ✅ Removed old breadcrumb functions (sniffly_update_breadcrumbs, on_breadcrumb_clicked)
- ✅ Wired up navigation callback
- ✅ Test build SUCCESSFUL
Build status: CLEAN (only unused parameter warnings)
Phase 6: Back/Forward Awareness - OPTIONAL (can skip)
This is an advanced feature from the plan. The basic breadcrumb works without it.
Phase 7: Testing - IN PROGRESS
TODO:
- Add history checking to draw function
- Dim backwards segments with transparency
Phase 7: Testing & Polish - PENDING
TODO:
- Test all navigation scenarios
- Performance profiling
- Visual polish

| 12 | - ✅ Implemented path parsing in `update_breadcrumb_cache()` |
| 13 | - ✅ Basic color coding (green root, red active, gray inactive, dark gray hover) |
| 14 | - ✅ Hit-testing function `find_segment_at_position()` |
| 15 | - ✅ Navigation on click (calls `scan_directory()`) |
