What changed

Enter no longer submits, renames or closes anything while an input method is composing. A shared isImeComposing(e) helper guards every text-field Enter handler listed in the issue.

Closes #42

Why

People typing Japanese, Chinese or Korean press Enter to pick a candidate from their input method. Our rename boxes, prompts and search fields treated that Enter as "submit". Renaming a note to 日本 saved the raw "にほん" and closed the box before the conversion could be chosen. Only the Escape path (overlay-escape.ts) checked for composition.

  • apps/web/src/ui/shared/utils/ime.ts (new): isImeComposing(e) checks isComposing || keyCode === 229. The keyCode check matters because Safari fires the confirming keydown after compositionend, with isComposing already false. The helper takes React's synthetic event or a native one. It is named isImeComposing so it doesn't clash with the panes' isComposing() handle.
  • Guarded handlers: folderTree (the rename box and the new-folder box), the workspacePanel rename, PromptDialog, ConfirmDialog's title field, findReplace (find and replace), urlImportDialog, the graphView search, the cardsView title, MathNodes and consolePanel.
  • searchPanel returns early on any key while composing, because Escape and the arrow keys belong to the input method then too.
  • Not changed: row and grid navigation handlers (the folderTree/workspacePanel row keydown, tableGridPicker, the walkthrough). They aren't text inputs, so no composition reaches them.

How to verify

Automated: apps/web/src/__tests__/ime-enter.test.jsx (17 cases) covers:

  • the helper on a native composing event, on keyCode 229, on an ordinary Enter and on a React synthetic event;
  • PromptDialog: a composing Enter (isComposing or keyCode 229) does not call onConfirm, and a normal Enter afterwards still submits 日本;
  • a source scan that pins the guard in each of the 10 handler files, so a new or refactored handler that drops it fails CI.

With the handler changes reverted, 12 of the 17 cases fail.

Manual check (Chrome, macOS Japanese – Romaji input), shown in the video: rename a note to 日本語. Type nihon, press Space, pick 日本 and press Enter, then type go, press Space, pick 語 and press Enter.

  • Before: the first Enter (the one accepting 日本) commits the rename and closes the box, so the name is cut off at 日本 and go lands outside the field.
  • After: each Enter only accepts its candidate and the box stays open. A final Enter saves 日本語.

I also checked both builds in Chrome with a real composition driven through CDP (Input.imeSetComposition, as e2e/cases/journeys.mjs does). Before the fix the box closed on the IME's Enter; after it, the box stayed open with 日本 and the next Enter saved it.

Commands, run from the repo root on Node 23 / Bun 1.4.4:

Command Result
bun run lint passed, 0 errors
bun run typecheck passed
bun run --cwd apps/web test 4520 passed, 10 skipped
bun run build passed

The editor suite is the part this change touches. I did not run the database-backed API tests (bun run db:up) because nothing in apps/api changed.

AI assistance

Claude Code helped find the handlers and drafted the helper, the guards and the test. I reviewed every change, checked that the test fails without the fix, and tested the behaviour by hand with the macOS Japanese input method.

Checklist

  • bun run lint && bun run typecheck && bun run test && bun run build passes from the repo root (editor suite run; the API database cases were not run because apps/api is untouched)
  • Tests added or updated (apps/web/src/__tests__/ime-enter.test.jsx)
  • I understand every line of this change and tested it myself
  • I read the relevant part of CLAUDE.md and apps/web/CLAUDE.md and did not undo a documented invariant
  • No renaming of the perssonify data identifiers
  • No Tiptap node or mark added
  • This PR contains no security fix that should have gone through private disclosure

Screenshots

See the video above (no visual or colour change).

Enter confirms an IME candidate (Japanese, Chinese, Korean), but the
rename boxes, prompts and search fields treated it as "submit", so
renaming a note to 日本 committed the raw にほん. Add a shared
isImeComposing() helper (isComposing, or keyCode 229 for Safari) and
return early from every text-field Enter handler listed in Perssonify#42.

Closes Perssonify#42

📝 Walkthrough

A shared isImeComposing helper detects composition in native and React keyboard events, including keyCode 229. Text-field Enter handlers use the helper to prevent actions during composition. Tests cover the helper, PromptDialog, and handler integration.

Changes: IME-aware keyboard handling

Layer / File(s) Summary
Composition detection and tests
apps/web/src/ui/shared/utils/ime.ts, apps/web/src/__tests__/ime-enter.test.jsx
The helper checks native or React keyboard events for isComposing or keyCode 229. Tests cover the helper, PromptDialog behavior, and guarded handlers.

Composing text with a modified Enter can prematurely submit an equation or commit or close a card. These bounded cases should be fixed; the rename test should also check the behavior directly.

Explanation

Directly linked issue #42 has three acceptance criteria. Criteria 1 and 2 are met for the listed text-field handlers. Criterion 3 is met by the new test file.

Helper: apps/web/src/ui/shared/utils/ime.ts exports isImeComposing(e). It returns true when isComposing is true or keyCode is 229. It unwraps React's nativeEvent. This matches the suggested isComposing(e) helper in #42. The name differs, and the issue allows this ("for example").

Guards: The reviewed head confirms the guard in ui/find/searchPanel/index.tsx (early return on any key during composition) and in ui/dialogs/index.tsx (PromptDialog Enter branch uses !isImeComposing(e)). The change summaries for folderTree, workspacePanel, confirmDialog, findReplace, urlImportDialog, graphView, cardsView, MathNodes and consolePanel describe the same guard. I did not read those files at head. Their guard is supported by the change summaries and by the source-scan expected counts in the test, not by direct file reads.

Tests: apps/web/src/__tests__/ime-enter.test.jsx (17 cases at head) covers the helper, a behavioural PromptDialog check (composing Enter does not confirm; later Enter confirms 日本), and a source scan of the 11 listed handler files. The scan checks for the import and a set number of isImeComposing(e) calls. It does not check that each call sits in the Enter branch. The test therefore pins the guard's presence, not its exact placement.

The #42 suggestion of a Chrome DevTools end-to-end case is a suggestion, not an acceptance criterion. Its absence does not fail this check.

Not verified: I did not run the test suite. The PR's reported command results and revert results are not confirmed here.

Full details: Out of Scope Changes check

Explanation

All changed files relate to #42. The changes are the new helper ui/shared/utils/ime.ts, the Enter guards in the handler files listed in #42 (folderTree, workspacePanel, dialogs, confirmDialog, searchPanel, findReplace, urlImportDialog, graphView, cardsView), and the two files #42 marks as "worth checking" (MathNodes.tsx, consolePanel). The test file apps/web/src/__tests__/ime-enter.test.jsx supports the change. The PR does not touch apps/api, and the reported changes contain no unrelated refactor, rename or documentation edit. The PR describes the unchanged row and grid navigation handlers as intentionally excluded. Those handlers are not in the changed-file list.

Limit: The whole-PR diff could not be read because changed blobs are missing from the checkout. The file list comes from the change summaries and the PR description, not from a diff read.

Explanation

The pull request description follows the repository template and clearly explains the change, motivation, verification steps, AI assistance, checklist status, and screenshots. It also transparently identifies that database-backed API tests were not run because the API was unchanged.

Quton review

TL;DR Enter on text fields no longer submits, renames or closes anything while an input method (Japanese, Chinese, Korean) is composing. A new shared helper isImeComposing(e) checks isComposing or keyCode === 229 (for Safari's late confirming keydown). It now guards the Enter handlers in ten UI files.

Lane: Lite (138 changed source lines, no risky paths). Reviewed 13 of 13 files.
Effort: 2 of 5, about 15 minutes. Merge risk: Low.

Findings

No issues found in the reviewed changes.

What changed in behavior

  • Pressing Enter to confirm an IME candidate no longer commits a rename in folderTree (folder and document rows) or the workspacePanel flat list.
  • PromptDialog, the new-document title in confirmDialog, urlImportDialog, consolePanel, the graphView search, the cardsView title, the MathNodes source input, and findReplace (find and replace) all ignore Enter while composing.
  • searchPanel ignores every key while composing, including Escape and the arrows, not only Enter.
  • On Safari, a keydown with keyCode 229 is treated as composing even after compositionend, so that Enter does not submit.

Suggested review order

  1. apps/web/src/ui/shared/utils/ime.ts: the detection logic every guard relies on
  2. apps/web/src/ui/find/searchPanel/index.tsx: the one handler that swallows all keys, not just Enter
  3. apps/web/src/ui/workspace/folderTree/index.tsx: the reported rename bug
  4. apps/web/src/tests/ime-enter.test.jsx: confirm coverage and the source-scan list
  5. Remaining handler files: identical one-line guards

Tests

Only PromptDialog is tested behaviorally. The other nine files are covered by a source scan that counts guard occurrences, which proves the call exists but not that it sits in the right condition. Unguarded Escape handlers in rename boxes and dialogs can still cancel mid-composition, and no test covers that.

If a composing Enter carries Ctrl or Meta, this handler still calls submit(). The dialog can submit the value before IME conversion finishes. Add !isImeComposing(e) to this condition.

Guard modified Enter in both card text fields.

If a composing Enter carries Ctrl or Meta, these handlers still call commitComposer() or finish(). The composer can clear its draft, or the card editor can save and close, before the converted text arrives. Apply !isImeComposing(e) to both shortcuts, as the title-field handler does.

Exercise the workspace rename handler with composing Enter.

apps/web/src/__tests__/behave-library.test.jsx:199-208 tests only ordinary Enter. The source-count test checks helper occurrences, not whether onRenameSubmit() is guarded. Add a composing-Enter case that asserts onRename is not called.
