Changelog

v0.1.5 (2026-06-29)

Window-Switch Engine Reset

• Engine state now clears on window switch — when Alt+Tab'ing between apps, the composition buffer is properly reset before the next keystroke. Previously, keystrokes could still apply Vietnamese tone/mark rules across app boundaries, producing corrupted text.
• last_key_time only on character key presses — modifier-only events (Alt, Ctrl, Shift) no longer update the gap timer, so the 100 ms inline xprop poll fires reliably after every window switch, regardless of held modifiers.

Active Window Detection

• xprop fallback — get_active_window_id() tries xdotool first, falls back to xprop -root _NET_ACTIVE_WINDOW (preinstalled x11-utils). Works under sudo even when xdotool is absent.

Code Cleanup

• Removed ~400 lines of dead unsafe code — entire X11 clipboard shared-state block (unsafe statics, manual Xlib dlopen, SelectionRequest handling) was unused and has been deleted. All related #[warn(dead_code)] and #[warn(static_mut_refs)] warnings eliminated.
• Engine dead code removed — unused methods is_empty, is_tone_or_mark_key, process_string, last_base_char, apply_cluster_mark, apply_mark in BambooEngine; RuleEffect enum and special_rules field in InputMethodRules.
• Production logging — per-key eprintln! removed from evdev loop and uinput paste path. Only startup/error/window-change messages remain (log_info to both stderr and file).

Flatpak Build & System Tray

• System tray (vietc-tray using ksni/DBus StatusNotifier) is now built and included in the Flatpak bundle. The tray launches the daemon and shows Vietnamese/English mode.
• Desktop menu entry — the app now appears when searching "Viet+" in the application menu. Search, launch, or uninstall from there.
• Flatpak command changed from vietc-daemon to vietc-tray (the tray spawns the daemon).
• Tray fixes for Flatpak — find_sibling_binary() now tries {name}-daemon fallback; is_daemon_running() checks both vietc and vietc-daemon process names.
• Fixed mkdir -p — build-flatpak.sh now creates /app/share/applications before installing the desktop file.

Active Window Detection (Flatpak fix)

• Native X11 _NET_ACTIVE_WINDOW query via dlopen("libX11.so.6") — added as third fallback in get_active_window_id(). Works inside the Flatpak sandbox where xdotool/xprop are unavailable. No subprocess, no external dependencies.
• Bundle: VietPlus-0.1.5.flatpak (66 MB with tray, runtime org.gnome.Platform//50). Warning-free build.
