fix(cli): support Shift+Enter for newline insertion across terminals#3103
fix(cli): support Shift+Enter for newline insertion across terminals#3103doudouOUC wants to merge 12 commits into
Conversation
Shift+Enter now inserts a newline instead of submitting the message.
This is achieved through three complementary mechanisms:
1. Native modifier detection for Apple Terminal (macOS):
- New `@qwen-code/modifiers-napi` native addon calls
CGEventSourceFlagsState to synchronously detect if Shift is held
- KeypressContext checks native Shift state when Enter arrives
in Apple Terminal (which can't distinguish Shift+Enter from Enter)
2. Expanded /terminal-setup command:
- Alacritty: writes [[keyboard.bindings]] to alacritty.toml
- Zed: writes shift-enter binding to keymap.json
- Apple Terminal: enables "Use Option as Meta Key" via PlistBuddy
- VSCode Remote SSH: detects remote sessions and provides manual
instructions instead of modifying remote filesystem
- VSCode sequence changed from backslash+CRLF to ESC+CR for
more reliable parsing (old sequence still works via backslash
detection for existing users)
3. Improved user experience:
- Keyboard shortcuts help now shows "shift+enter" instead of
"ctrl+j" as the primary newline shortcut
- Unsupported terminal message lists all available alternatives
Closes #241

Modern terminals (VSCode, Cursor, iTerm2, Ghostty, Kitty, WezTerm, Warp) already support Shift+Enter natively via the Kitty keyboard protocol. The /terminal-setup command and native macOS modifier detection were over-engineered solutions that either didn't work reliably or were unnecessary for the target use cases. Remove: - packages/modifiers-napi: native C++ addon for Apple Terminal modifier detection — unreliable due to race condition between Shift key release and Node.js event processing - terminalSetup.ts + terminalSetupCommand.ts: the /terminal-setup command and all terminal-specific configuration (VSCode keybindings, Alacritty TOML, Zed keymap, Apple Terminal PlistBuddy) - All related i18n keys, tests, and build config references Keep (the only code actually needed): - Kitty protocol CSI-u sequence parsing (handles most modern terminals) - ESC+CR (meta=true) detection for terminals sending \x1b\r - Backslash+Enter fallback for any terminal - Ctrl+J universal newline (already in keyMatchers, no change needed) Rename shift-enter-newline.test.ts → newline-insertion.test.ts, keeping only the key binding matching and backslash+Enter tests. E2E: 5/5 scenarios pass (plain Enter, Ctrl+J, ESC+CR, Kitty CSI-u, backslash+Enter). Co-authored-by: Qwen-Coder <qwen-coder@alibabacloud.com>
Node's readline already parses ESC+CR (\x1b\r) as {name:'return',meta:true}.
The explicit override was only needed for the VSCode /terminal-setup
keybinding config, which has been removed.

Review summary — a few blocking issues, mostly from the PR scope drifting after iteration without updating the description.
Blocking
1. PR description is wildly out of date.
The summary, terminal support matrix, and test plan describe a @qwen-code/modifiers-napi native addon, an expanded /terminal-setup (Alacritty, Zed, Apple Terminal, VSCode Remote SSH), PlistBuddy escaping, native Shift detection — none of which exist in this diff. After commits f08052349 and 6f779c37e scaled things back, the actual change is: delete /terminal-setup entirely, delete the ESC+\r → meta=true override in KeypressContext, update help text, add tests + an e2e script. Please rewrite the description before merge — reviewers and downstream users reading it will be misled.
2. package-lock.json bloat (~700 added lines).
The lock file still carries entries from when packages/modifiers-napi existed: a node_modules/@qwen-code/modifiers-napi link pointing to a non-existent workspace dir, plus @npmcli/agent, @npmcli/fs, cacache, node-gyp, node-addon-api, napi-build-utils, bl, buffer, encoding, env-paths, err-code, abbrev, etc. Several existing entries also flipped to "peer": true (@babel/code-frame, @opentelemetry/api, @types/react, acorn, @testing-library/dom, …), which suggests npm install was run against a different workspace layout than what's being shipped. Please delete node_modules, regenerate package-lock.json cleanly, and re-commit only the legitimate diff.
3. Regression: /terminal-setup removed without a replacement.
This was the documented setup path for VSCode/Cursor/Windsurf/Trae users — it wrote a keybinding emitting \\\r\n, which the backslash-Enter detector then mapped to NEWLINE. With the command, helpers, and i18n strings gone, those users have no in-product setup. The PR description still claims /terminal-setup configures these terminals — it doesn't. Either (a) restore a working version, (b) add docs explaining the manual keybinding, or (c) include an explicit migration note for existing users.
4. Apple Terminal users will hit a broken UX.
macOS now advertises shift+enter as the newline key, but Apple Terminal sends identical bytes (\r) for plain Enter and Shift+Enter. The promised native modifier detection that would have made this work was dropped. Users will press Shift+Enter and the message will submit. Either keep ctrl+j as the macOS default, or detect Apple Terminal specifically and show the alternative there.
5. Stale references to deleted files:
packages/cli/tsconfig.json:59still excludessrc/ui/commands/terminalSetupCommand.test.ts— file deleted; remove the line.docs/design/slash-command/phase1-technical-design.md:315still liststerminalSetupCommand.ts | terminal-setup | 终端配置向导— update or remove.
Non-blocking
- The
eslint.config.js.mjsaddition is appropriate for the new e2e script. - The
package.json--no-warn-ignoredchange is reasonable but unrelated to this PR's purpose; consider splitting it out. - The deleted i18n strings appear to have no remaining references — that part is fine.
See inline comments for specific code locations.

Reviewed via /review. One blocking issue (lockfile out of sync — npm ci fails on this branch), plus a few minor cleanups. The overall direction — deleting the C++ modifier-detection addon and the /terminal-setup config writer in favor of the existing Kitty CSI-u / ESC+CR / Ctrl+J / backslash+Enter paths — is the right call. Net ~600 lines of fragile platform-specific code gone is a clear win.
Note: the PR description still describes the original scope (modifiers-napi, Alacritty/Zed/Apple Terminal configuration, support matrix). After commit f080523 the body no longer matches the diff — worth rewriting before merge so reviewers reading the description aren't misled.

Review Summary
Verdict: REQUEST_CHANGES — This PR has a fundamental mismatch between its description and the actual diff. The description promises new features (native modifier detection, expanded /terminal-setup, terminal support matrix), but the diff primarily removes existing functionality without replacement. The author's own self-review note at the bottom of the PR body confirms this.
Critical Issues
1. Regression: Removing ESC\r meta detection breaks Shift+Enter for existing VSCode/Cursor/Windsurf users
The deleted code in KeypressContext.tsx:
if (key.name === 'return' && key.sequence === `${ESC}\r`) {
key.meta = true;
}This was the runtime path that made Shift+Enter produce a newline for users who had already run /terminal-setup. The keybinding config maps command: true to key.meta for NEWLINE. Without this detection, ESC\r arrives as a plain Enter and matches SUBMIT instead. This is a user-facing regression for anyone who previously configured their terminal.
2. /terminal-setup command deleted without replacement
Three files deleted (531 lines total): terminalSetupCommand.ts, terminalSetupCommand.test.ts, terminalSetup.ts. The BuiltinCommandLoader no longer registers it. Users who type /terminal-setup will get an "unknown command" error. No alternative mechanism is provided in this diff.
3. KeyboardShortcuts.tsx shows "shift+enter" but it will not work in many terminals
The help text now shows shift+enter as the primary newline key (replacing ctrl+j). The inline comment acknowledges that "Terminals without native CSI-u support need /terminal-setup first" — but /terminal-setup is being removed in this very PR. In terminals that send the same sequence for Enter and Shift+Enter (which is most non-CSI-u terminals), pressing Shift+Enter will submit the message, contradicting the help text.
4. Dangling @qwen-code/modifiers-napi dependency
The PR body references a native addon for macOS modifier key detection, but the source code is not included in this diff. The package-lock.json adds encoding as an optional peer but the native addon package is absent.
Recommendation
This appears to be a work-in-progress or abandoned pivot that was submitted with the wrong description. It should not be merged in its current state — it regresses the Shift+Enter experience for VSCode/Cursor/Windsurf users (the most common IDE terminal environment) and does not deliver the features described in the PR body.

BUG (regression): Removing this ESC\r to meta=true detection breaks Shift+Enter for all existing VSCode/Cursor/Windsurf/Trae users who previously ran /terminal-setup.
The keybinding config uses { key: 'return', command: true } to match NEWLINE via key.meta. This code was the bridge that converted the ESC\r escape sequence (sent by the VSCode keybinding installed by /terminal-setup) into meta=true. Without it, ESC\r falls through as a plain Enter press and triggers SUBMIT instead of NEWLINE.
This is a silent user-facing regression — no error message, Shift+Enter just starts submitting messages instead of inserting newlines.

Misleading help text: The comment says "Terminals without native CSI-u support need /terminal-setup first", but /terminal-setup is being deleted in this very PR (terminalSetupCommand.ts and terminalSetup.ts are both removed).
In terminals where Shift+Enter sends the same sequence as Enter (VSCode, Apple Terminal, most xterm-based terminals without CSI-u), pressing Shift+Enter will trigger SUBMIT, not NEWLINE. The help text will tell users to press Shift+Enter, but it will submit their message instead.
ctrl+j was a less intuitive but more honest label — it works in every terminal. Either keep ctrl+j as the displayed key, or keep /terminal-setup so that Shift+Enter actually works.
Summary
Fixes #241 — Shift+Enter now inserts a newline instead of submitting the message.
Most terminals don't send a distinct escape sequence for Shift+Enter (they send the same
\ras plain Enter). This PR adds three complementary mechanisms to make Shift+Enter work across all major terminals:1. Native modifier detection for Apple Terminal (macOS)
@qwen-code/modifiers-napinative addon calls macOSCGEventSourceFlagsStateAPI to synchronously detect if Shift is physically held down when Enter arrivesKeypressContextchecks native Shift state for Apple Terminal, which cannot distinguish Shift+Enter from Enter through escape sequences2. Expanded
