- Add WriteFile method to mock filesystem (non-atomic path, creates files)
- Implement WriteFileAtomic in mock with temp file + rename pattern
using .tmp/ directory, matching real filesystem semantics
- Update WriteFileTask.Execute() to use WriteFileAtomic
- Update FlushAll() to use WriteFileAtomic
- Fix mock to create files on write (matching os.WriteFile behavior)
- Update tests to match new semantics (create-if-not-exists)
- Define pool.FileSystem interface in internal/io/pool/filesystem.go
- Move DirEntry interface to internal/io/pool/types/types.go to break
the pool <-> mock import cycle
- Implement real.FileSystem with atomic writes (temp file + os.Rename)
- Update mock.FileSystem to satisfy pool.FileSystem interface
- Update worker pool tasks to accept pool.FileSystem interface
- Update main.go to use RealFileSystem by default, with -root flag
- Update all browser/editor/test references to types.DirEntry
- Replace gtx.Event(nil) with key.Filter{Focus: focusedID} and
key.FocusFilter{Target: focusedID} so Gio correctly routes key
and edit events to the focused editor text field.
- Convert EditorState.CursorPosition (byte offset) to line/column
coordinates for accurate cursor rendering.
- Add debug logging in HandleKeyDown and HandleCursorMove.
- Changed BrowserScrollOffset and ListView.ScrollOffset from int (row index)
to ui.Dp (pixel offset) for smooth per-pixel scrolling
- Updated HandleBrowserScroll to use raw Dp delta instead of row-based
scrolling with minimum ±1 row jumps
- Fixed search not triggering new frames by detecting query changes in
main.go FrameEvent handler
- Fixed click misalignment by indexing RowFilenames with local index i
instead of rowGlobalIndex
- Fixed bottom clamping using actual BrowserListHeight and corrected
formula: maxScroll = totalRows * rowHeight - BrowserListHeight
- 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
- Fix render.go: replace broken material.Label with shaper-based text
rendering (LayoutString + Shape + glyph iteration) per Gio's paintGlyph
- Fix render.go: only apply clip rects at container boundaries; leaf
elements have zero-size regions that were clipping all text out
- Fix render.go: call r.drawElement recursively for container children
so nested containers work and clips are applied correctly
- Fix render.go: add drawLineText/drawLine helpers matching Gio's
paintGlyph offset calculation (x + first.X, y + first.Y)
- Fix element.go: Button.Draw now uses r.drawText instead of duplicate
broken material.Label code; Label defaults to black when color is unset
- Fix state.go: container children use relative coordinates instead of
mixed screen-space/container-relative positions
- Fix main.go: ConfigEvent carries raw pixel dimensions only; ScaleEvent
carries scale only; layout is computed once per frame using both,
eliminating the infinite Invalidate() loop
- 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
- Remove Renderer.scale field and SetScale method
- Add ScaleProvider interface to avoid editor/ui import cycle
- Add Scale() method to State, rename Scale field to scale
- Renderer reads scale through r.scale.Scale()
- Fix icons.go blank import preventing embed.FS usage
- Update main.go to pass State as ScaleProvider to Renderer
- StateReader interface in ui package (Scale(), ScreenWidth(), ScreenHeight())
- State implements StateReader
- Renderer reads scale/window size via interface, never imports editor
- State fields are private (screenWidth, screenHeight, scale) with accessor methods
- No SetScale/SetWindowSize calls from main.go — Renderer reads from State directly
- ConfigEvent: ONLY from app.ConfigEvent, sets width/height in State
- FrameEvent: gets scale from gtx.Metric.PxPerDp, sends ScaleEvent only if changed
- ScaleEvent: updates State.Scale
- Renderer reads windowW/windowH from State (SetWindowSize), not gtx.Constraints
- Renderer reads scale from State (SetScale), not gtx.Metric.PxPerDp
- main.go: ConfigEvent calls SetWindowSize, FrameEvent calls SetScale
- State.Scale stores the scale factor (default 1.0)
- ScaleEvent applies SetScale() which updates State.Scale
- Logic.Scale() accessor returns current scale
- Renderer.SetScale() updates renderer's scale from State
- main.go: uses logic.Scale() to get scale, calls renderer.SetScale()
- No more references to gtx.Metric.PxPerDp in render.go or main.go
- ConfigUpdate interface with apply(*State) method
- ConfigEvent and ScaleEvent both implement ConfigUpdate
- Logic.ConfigChan() accepts both types
- Type switch in Run() differentiates ConfigEvent vs ScaleEvent
- main.go sends both on same ConfigChan()
- Logic layer has separate ConfigChan and ScaleChan
- ConfigEvent: width/height in Dp, set on ConfigEvent
- ScaleEvent: scale factor, set on FrameEvent when scale changes
- Logic has ScreenSize() accessor for layout/rendering pipeline
- Logic has SetScale() to update scale and recompute layout
- main.go: ConfigEvent stores pixels, converts to DP using current scale
- main.go: FrameEvent gets actual scale, sends ScaleEvent if changed
The op.Record macro was leaving a clip on the stack that prevented
subsequent elements from drawing. Use clip.Rect{}.Push()/clip.Pop()
instead for immediate push/pop.
- 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
- Create internal/editor/state.go with State struct and EditorLayout
- Create internal/editor/logic.go with Logic struct and Run method
- Logic owns all state, provides channels for config, frames, input, results
- Main goroutine uses editor.NewLogic() and logic.Run()
- Proper separation for testing later

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.
