Frame now carries view state (scale/focus/query) to the main goroutine,
which reads only the frame-receiver-stored snapshot. Renderer owns Gio
widget editors (registered by ID) and the draw scale. Autosave timer
sends a token to the logic goroutine instead of touching state;
Shutdown waits for the owner to exit before FlushAll.
Tests access state only through owner-side Inspect/WithState helpers
(harness + in-package). Fixed double-Harness.Run race in two e2e tests,
made TestWorkerPool_PriorityPreemption deterministic, and raised the
lazy-loading test timeout that was too short under -race.
go test -race ./... is now green.
- JNI: open_file_in_termux via ACTION_SEND intent (text/plain + file:// uri),
global context ref kept from registerFragment
- impl_android.go: OpenFile(path) attaches current thread if needed
- NewLogic takes openfunc; State.open + ui.OpenFile now func(string)
- ChunkedBuffer.VisibleByteRange: word-wrap path using
GlyphLayout.VisualLineStarts (+byteOffset, lineHeight, visual index param)
- GlyphLayout gains LineHeight; drawWrappedText records VisualLineStarts
- WordWrap default true; State.ByteOffset tracks first visible line
- types: VisualLineIndex
- scroll_fix_test.go (new)
- debug prints left in place (WIP; cleanup in later phase)
- 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)
- Fix cursor vertical alignment and ensure it respects ScrollOffset.
- Fix scrolling in editor page by correctly registering scroll interactions in the renderer.
- Ensure cursor is clipped to the editor text area to prevent drawing over status bars.
- 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.
- Remove currentBrowserState global and SetBrowserState from browser package
- Browser now receives sortHandler as a parameter instead of using global state
- Fix sort mode toggle: reload pages after clearing cache (was showing 'Loading...')
- Add String() methods to all UI element types for debugging
- Add e2e tests for sort mode functionality (5 tests)
The editor now owns all state; the browser is a pure function receiving
state and handlers through parameters.
- 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
- Add clippableElement interface for elements that need their own clip region
- ListView implements NeedsClip() so drawElement pushes a clip before Draw
- RegisterScroll no longer has its own clip; relies on element clip context
- Aligns with Gio's clip-based gesture registration model
- Fix scroll events firing outside the visible list area on browser page
Also:
- Update touch.md documentation to reflect clip-based interaction model
- Remove debug logging from ListView.Draw
- Remove TODO-click-fixes.md (all items resolved)
- Added Page state (BrowserPage/EditorPage) and SortMode
- BrowserLayout with 30 static entries, sort toggle, search placeholder
- ListView rows clickable via per-row RegisterClick
- Scroll gesture registered at START of ListView.Draw (before clicks)
so click gestures registered later are checked first during hit test
- Unique IDs for interactive elements: editor_text, browser_list, search_bar
- ListView.Interactions() filters out Scroll (registered in Draw, not registerInteraction)
- RegisterScroll added to Renderer, called from element Draw methods
- lastLineYChan frame loop fixed: only re-layout if value changed
- Back icon added, editor status bar shows active filename
- 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
- 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.
