- Renderer computes word wrap via single LayoutString pass with
WrapHeuristically policy; glyphs drawn inline at FlagLineBreak
- Fixed line height (fontSize * 1.2), independent of glyph metrics
- Two-finger trackpad scroll via gesture.Scroll with vertical axis
- Display line feedback: renderer reports last glyph Y after each
Draw; logic uses it to clamp scroll offset so last line stops
at bottom of viewport with lineHeight/2 padding
- ScrollRange fix: {Min: -(1<<30), Max: 1<<30} ensures scroll
delta is consumed (empty range consumes nothing via clampSplit)
- Line counting fix: only FlagLineBreak increments count; buffer
flushes (32-glyph cap) draw but don't count
- Add ui.Dp and ui.Px as distinct named types
- Logic layer works exclusively in Dp (positions, sizes, regions)
- Renderer converts Dp→Px at Gio interop boundaries
- Capture gtx.Constraints once at start of Draw() for consistent positioning
- main.go converts app.ConfigEvent pixels to Dp before passing to logic layer
- Update documentation with new coordinate system architecture
Elements implemented:
- StatusBar (top bar with filename, action icons, conflict/search icons)
- BottomBar (bottom bar with cursor position, byte position, word wrap button)
- Button (interactive button element)
- AlphaIndex, SearchBar, Cursor, MergeHunk, Toast, Spacer (stubs)
Layout:
- EditorLayout function computes regions for StatusBar and BottomBar
- Filename truncation with ellipsis (mocked filename for testing)
- Mocked data: "very_long_filename...", "Ln 47, Col 12", "1024 / 50000"
Renderer:
- drawStatusBar: draws filename line + icon line
- drawBottomBar: draws cursor pos, byte pos, word wrap button
- drawButton: draws button text
- drawIconButton: draws icon buttons
Window resize:
- configChan setup in main.go
- ConfigEvent handling in event loop
- Layout recomputation on resize
Builds and runs successfully.
