- Add Draw(gtx, r *Renderer) to Element interface
- Add Container type that implements Element and holds []Element children
- Leaf types (Label, Icon, Button) implement Draw themselves
- Single recursive drawElement function in Renderer — no switch/case
- Remove StatusBar/BottomBar — replaced by Container
- Remove shaper.go — no longer needed with Gio material labels
- Simplify main.go — scale via ScaleProvider interface
- 5 files changed, shaper.go deleted
- New shaper.go: ShapeText() returns ShapedText with measured width +
stored PathSpec + BitmapsCall, DrawShapedText() draws with zero shaper calls
- drawStatusBar: ShapeText for filename + right icons, positions from widths
- drawBottomBar: ShapeText for cursor/bytepos/wrap, positions by alignment
- No separate measureText helper: ShapeText.Width provides measurements
- StatusBar uses IconLeft/IconRow string slices for icon configuration
- BottomBar uses BarAlignment enum for item positioning
- 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.
