feat(input): preserve Kitty repeat ownership by chuxubank · Pull Request #378 · RizRiyz/luvus

chuxubank · 2026-09-16T01:10:57Z

Summary

implement Kitty REPORT_EVENT_TYPES across supported key families while preserving Legacy auto-repeat
keep pane Press/Repeat/Release ownership client-scoped and release held keys during every client lifecycle cleanup path
classify UI repeats beside each semantic branch with UiRepeatDisposition::{Suppress, Reprocess}
replay the original Press only through the exact receiver that accepted it, while keeping activation, confirmation, mutation, capture, and other actions Press-only
pin federated Repeat/Release to the client or exact server endpoint that consumed Press

Why this design

The previous revision represented repeatable behavior as typed semantic motions and replayed those through a central router. That duplicated behavior across the original handler, a dispatch mapping, and an applier; it also made established receiver semantics easier to change accidentally.

This revision removes that extra semantic layer. Existing handlers remain the single source of truth and return an explicit repeat disposition next to the branch they execute:

Reprocess is used only for continuous editing/navigation.
Suppress is the fail-closed default for actions and side effects.
Repeat reuses the original Press only after validating the same receiver before and after dispatch.

This is intentionally not a central KeyCode allowlist and uses no ambient “repeat allowed” state. The same key may repeat in one semantic context and remain Press-only in another.

Review fixes

restored DIFF Left/Right old/new source-side selection
made FILES expansion/collapse report render changes even when the cursor does not move
preserved Git Status j/k scrolling separately from Up/Down changed-file selection
kept Mission detail overlays authoritative over background list navigation
tracked federated physical-key ownership across overlay and endpoint changes
released held pane keys when any broadcast path removes a disconnected client
suppressed idempotent Picker Home repeats that would repeatedly refresh the directory
invalidated Scroll/Copy repeat receivers when API focus moves to another pane

Behavior covered

pane-owned phases remain authoritative across focus and client changes
received pane Repeat/Release modifiers are forwarded verbatim; only lifecycle cleanup synthesizes Release from the original Press
UI lease identity remains client + semantic key + keypad state; modifiers are intentionally excluded
DIFF Space remains an action and does not repeat; File and Preview Space continue to page
Search text Repeat replays the original insertion even if later host modifier state changes
ORCH choice actions remain Press-only while list navigation can repeat
Legacy terminals retain their historical indistinguishable Press auto-repeat behavior

Validation

cargo fmt --all --check
cargo clippy --all-targets --locked -- -D warnings
cargo test --locked repeat -- --nocapture — 14 passed
focused DIFF, FILES, Git Status, Mission detail, federated ownership, broadcast cleanup, Picker Home, and API-focus regressions
cargo build --release --locked
git diff --check
Opus 5 P0/P1 review; its two concrete follow-up findings (Picker Home and API focus) were fixed and regression-tested

The full locked suite reached 1949 passing tests with 6 ignored. Seven unrelated linked-worktree checkout/sidebar/render-topology tests remain the same known baseline failures; this change did not expand that set.

Greptile Summary

This update improves Kitty key-event phase handling across UI receivers, panes, IPC clients, and federated endpoints. It preserves key ownership for repeat and release events, cleans up held-key state when clients and endpoints disconnect, and includes regression coverage for repeat routing and cleanup behavior.

The previously reported DIFF side-navigation and picker word-deletion repeat issues are fixed in the current code.

📝 Summary

Summary by CodeRabbit

New Features
- Added consistent held-key support for navigation, scrolling, search, and text editing across the application.
- Keyboard input now preserves key ownership across clients and correctly handles key presses, repeats, and releases.
Bug Fixes
- Prevented one-time actions such as toggles, selections, and menu commands from repeating when keys are held.
- Released keyboard state when clients disconnect or lose communication.
- Preserved scrollback position during repeated key forwarding and cleared stale repeat states after mouse input.

Walkthrough

The pull request adds repeat-aware keyboard dispatch across application views, preserves key ownership across federated clients, releases held keys during client cleanup, and enables Kitty keyboard event-type reporting.

Changes

UI motion dispatch

Layer / File(s)	Summary
Motion model and repeat routing `src/app/mod.rs`, `src/app/input.rs`	Adds shared repeat dispositions, dispatch results, repeat leases, event-phase routing, forwarding helpers, and Kitty event encoding.
Workspace and menu integration `src/app/mod.rs`	Workspace, agent, rename, menu, and worktree handlers classify navigation and text edits for repeat processing.
Board and form motion handling `src/app/board.rs`, `src/app/picker.rs`, `src/app/mission.rs`, `src/app/session_menu.rs`, `src/app/settings.rs`, `src/app/switcher.rs`	These handlers reprocess safe navigation and text-edit keys and suppress one-shot actions.
File, diff, Git, preview, and search views `src/app/files.rs`, `src/app/diff.rs`, `src/app/git.rs`, `src/app/preview.rs`, `src/app/search.rs`	These handlers return dispatch results for scrolling, navigation, editing, and one-shot actions. Tests cover repeat behavior and changed-state reporting.

Client input phases

Layer / File(s)	Summary
Input phase filtering and cleanup `src/ipc/federated.rs`, `src/ipc/server.rs`	Federated input records the press owner and routes repeats and releases to that owner. Client lifecycle and delivery failures release held keys.

Terminal keyboard protocol

Layer / File(s)	Summary
Keyboard event protocol `src/main.rs`, `src/terminal/keyboard.rs`	The host requests disambiguated escape codes and event-type reporting. Tests verify the selected protocol flags.

In `@src/app/diff.rs`:
- Around line 1718-1721: Update handle_diff_key_dispatch so bare Left and Right
remain unmatched when selecting is false, allowing them to fall through to
handle_diff_key for selected_side changes; keep the selecting-specific side
motions and reserve Char('h') and Char('l') for Columns(-8) and Columns(8)
panning.

In `@src/app/files.rs`:
- Line 699: Update the lateral-motion change detection around file-tree
expansion so it reports changes when either the cursor or directory expansion
state changes. Have collapse_file_row_or_parent and expand_file_row_or_child
return whether they modified state, then combine those results with the existing
self.file_tree.cursor != before check.

In `@src/app/git.rs`:
- Around line 857-858: Update the key mapping around UiListMotion and
apply_git_motion so Char('j') and Char('k') produce the existing distinct
status-scroll motion, while KeyCode::Down and KeyCode::Up continue producing
UiListMotion::Step for changed-file selection.

In `@src/app/mission.rs`:
- Around line 577-583: Update the key handling around the UiListMotion dispatch
in handle_mission_key so that when mission_detail.is_some(), input is delegated
to the detail-overlay handling before processing j, k, Up, or Down as background
motion; preserve the existing press_motion behavior when no detail overlay is
open.

In `@src/ipc/federated.rs`:
- Line 5582: Update the key-event handling around the ClientMessage::Key release
branch to track client-owned pressed keys, consume their repeats and matching
releases until release, and forward those releases to the selected server.
Preserve server routing for releases whose original press was server-owned
before an overlay opened.
