The tree was formatted with an older gofmt; go1.27's gofmt additionally
wants: EOF exactly one newline (no trailing blank lines), imports sorted
alphabetically within a block, mixed-precedence binary expressions
re-spaced for grouping ((a+b)/c), single-field composite literals
un-aligned, adjacent one-line method signatures aligned, and one-line
bodies containing a compound statement expanded. Applied repo-wide
(31 files under internal/); pure formatting, no semantic changes —
build and the full test suite pass.
Selection handles now track the finger 1:1 (anchor grab point + displacement)
instead of snapping by whole lines, and crossing the opposite handle flips
the selection (native behaviour) instead of clearing it.
Caret and tap/handle line resolution use VisualLineStarts instead of the
min-Y baseline: the window's first visual line may be an empty line with no
recorded glyphs, which used to draw boundary carets one line too low per
leading empty line and land taps/dragged handles one line below the finger.
New exported ui.CaretPoint centralises byte->insertion-point mapping.
The off-screen caret no longer clamps to the window edge: EditorLayout ships
the true (possibly negative / past-end) window-relative cursor and the
renderer skips the caret when the cursor is outside the shaped window, so
scrolling past the caret no longer makes it jump onto the top/bottom line.
IME/router replay fixes: key.FocusCmd is issued only on a focus transition
(a per-frame no-op still takes the immediate-command path and re-queues all
pointer events), and the key.SelectionCmd IME sync is deferred while a
handle drag is in progress (each push re-injected the drag into every
gesture). Handle drags forward only Grabbed events; a tap inside a handle
grab box is a no-op.
Also: key.FocusEvent no longer logs as unexpected in main; dead code removed
(worker taskWrapper, browser applyXxxResult stubs, scrollIndex, mock_setup
sortModeKey/lineSpan helpers); mock FileSystem.ListPaths prefix match uses
strings.HasPrefix; build scripts run the new scripts/check.sh static gate
(go vet + staticcheck). Tests: caret_point_test, touch_selection updates
(flip/empty-line cases), off-window caret e2e, selection drag e2e grab step.
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.
When directory navigation fails (e.g., permission denied on Android),
the browser now restores the previous path instead of staying in a
broken empty state. NavigateTo saves the current path to History, and
handleError restores it and re-builds the index for the previous
directory when a BuildIndexTask fails.
