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.

# Build (and optionally install) the Pad Android APK for the local emulator.

# Usage:
|
|
# ./scripts/build_emu.sh # build + install to the connected device
|
|
# ./scripts/build_emu.sh --no-install # build only
|

#
|

|
|
# Prereqs on this workstation (the script checks each and explains what is
|
|
# missing):
|
|
# - JDK 17 (java on PATH)
|
|
# - Go + gogio v0.10.0 (~/go/bin)
|
|
# - Android SDK at ~/android-sdk (platform-tools, build-tools 35.0.0)
|
|
# - debug keystore at ~/.android/debug.keystore
|
|
# apktool is not a prerequisite: if it is missing, the script downloads
|
|
# v3.0.3 to the stable location ~/android-sdk/tools/apktool.jar.
|
|
#
|
|
# Why the apktool detour: gogio does not offer a way to add
|
|
# MANAGE_EXTERNAL_STORAGE to the manifest, and Android 11+ blocks the app's
|
|
# directory listing without it. So we decode the gogio APK, inject the
|
|
# permission, rebuild, and re-sign with the debug key.
