It stays pragmatic (no privileged paths by default), but leaves room for opt-in “power” methods and Phase 3 IME integration. - -Goals (KDE/Wayland first): -- Deliver reliable batch dictation into common apps with bounded latency. -- Use context signals (AT‑SPI2) to reduce mis-injection. -- Run multiple injector modules independently; choose the best available at runtime. -- Adapt when a method fails: skip it temporarily (cooldown) and prefer success-proven methods per app. -- Keep everything behind feature flags; default off unless explicitly enabled. - -Out of scope for this phase: -- Full IME integration (Fcitx5/IBus), per-app ML policies.

keep owner alive briefly. - - Optional restore previous clipboard after a short delay. -- Availability probe: Wayland display present; clipboard seat available. -- Pros: Reliable for batch; preserves formatting/newlines. -- Cons: Needs a paste trigger from another injector (AT‑SPI2/ydotool) or user. - -Implementation with proper lifetime management: -```rust -// clipboard_injector.rs -use wl_clipboard_rs::{copy::{MimeType, Options, Source}};

ensure clipboard owner lifetime. - -4) Ydotool Injector (Opt-in fallback) -- Feature: none new; behind config `allow_ydotool`. -- Runtime dep: `ydotool` daemon with permissions. -- Behavior: - - Either type text (`ydotool type --file -`) or send paste chord (Ctrl+V) after clipboard set. -- Availability probe: check `ydotool` and socket; refuse if not enabled. -- Pros: Broad coverage when enabled. -- Cons: Security/permission implications; keep explicit opt-in. - -5) IMe Injector (Phase 3) -- Feature: `text-injection-ime` (future). -- Deps: Wayland text-input v3 + input-method v2 via `wayland-protocols`/`smithay-client-toolkit` or zbus bridges to Fcitx5/IBus. -- Behavior: Commit text with semantic context (preedit, surrounding text, hints). -- Pros: Most context-aware. -- Cons: Larger integration cost; user UX considerations. - -6) Portal EIS Injector (Exploratory) -- Feature: `text-injection-portal-eis` (off by default). -- Deps: `ashpd` (xdg-desktop-portal), `reis` (pure-Rust libei) if applicable. -- Behavior: User-consented key events; still not semantic like IME. -- Caveat: Availability on KWin varies; treat as experimental. - -7) VKM Injector (Experimental) -- Feature: `text-injection-vkm` (off by default). -- Deps: Wayland client + unstable VKM protocol bindings. -- Caveat: KWin typically restricts VKM to trusted clients; expect unauthorized. - -8) Kdotool Assist (KDE-specific, opt-in) -- Feature: `text-injection-kdotool` (off by default). -- Deps: external CLI `kdotool` (no Rust crate dependency). -- Behavior: - - Window control only: find/activate/raise/move windows via KWin scripting. - - Use to assist focus/activation before AT‑SPI insert/paste; do not send keys via kdotool. -- Availability probe: Running under Plasma/KWin; binary present; DBus to KWin reachable. -- Pros: KDE-native focus/window control path; can improve success for AT‑SPI paste. -- Cons: Desktop-specific; not for keyboard/mouse synthesis; subject to KDE changes. - -9) Enigo Injector (uinput, invasive opt-in) -- Feature: `text-injection-enigo` (off by default). -- Deps: `enigo` (optional = true) — cross-platform input simulation via uinput on Linux. -- Behavior: - - Create virtual keyboard and type the batch string; or send paste chord after clipboard set. -- Availability probe: Can open `/dev/uinput` without root; udev rules applied. -- Pros: Mature, widely used; compositor-agnostic. -- Cons: Requires uinput permissions; kernel-level injection; potential interference with real input if misused. - -10) MKI Injector (mouse-keyboard-input, uinput, invasive opt-in) -- Feature: `text-injection-mki` (off by default). -- Deps: `mouse-keyboard-input` (optional = true). -- Behavior: - - Similar to Enigo; simple API to emit key sequences for batch text. -- Availability probe: Same as Enigo (`/dev/uinput`). -- Pros: Thin wrapper; predictable; compositor-agnostic. -- Cons: Same uinput caveats as Enigo. - - -## Strategy Manager (adaptive, bounded latency) - -Responsibilities: -- Construct an ordered chain from available injectors based on: - - Feature flags - - FocusStatus (ConfirmedEditable first tries AT‑SPI direct, etc.) - - Per-app success cache (prefer methods that worked recently for this app) -- Enforce per-call timeouts and a global budget (default ≤ 800 ms). -- Apply adaptive cooldown/circuit breaker per method and per app. - -Implementation example: - -```rust -// manager.rs -use std::collections::HashMap;

- Confirm AT‑SPI: `gsettings get org.gnome.desktop.interface toolkit-accessibility` (on KDE, ensure at-spi2-core is installed; accessibility generally on by default). - - Check `wl-copy` presence: `which wl-copy`. - - ydotool enabled? `systemctl --user status ydotoold` (or system scope depending on packaging). - -- “AT‑SPI2 injection does nothing” - - Target widget may not implement `EditableText` or may be read‑only. - - Focus may be on a container, not the text field — try clicking into the field first. - -- “IME commits are not appearing” - - Ensure your IME is the active input method in the system tray/selector. - - Validate D‑Bus calls succeed (enable debug logs) and that the engine is registered. - -- “ydotool permission denied” - - Ensure `ydotoold` is running; verify `/dev/uinput` permissions; consider `setcap` or group rules. -
