fix(desktop): configure composer spellcheck languages - #7745
Conversation
The packaged app pins Chromium to en-US, so correct Portuguese (and other) composer text is marked wrong when the OS locale is English. Infer Hunspell languages from the OS locale plus the keyboard layout, never set an empty dictionary list, and add a Settings toggle to disable or pick dictionaries. Fixes pingdotgg#7742 Co-authored-by: Cursor <cursoragent@cursor.com>

Effect service conventions review of the changed TypeScript: one finding in apps/desktop/src/electron/ElectronSpellcheck.ts (failure modeled as an untagged object literal instead of a Schema.TaggedErrorClass). The rest of the touched Effect code (namespace imports from effect/*, dependency acquisition via yield* Foo.Foo, no new ManagedRuntime/runPromise in service code, Schema additions in packages/contracts/src/settings.ts) looks consistent with the conventions.

The scope (~1400 lines of new functionality) represents a significant new capability rather than a simple fix. You can add or adjust custom eligibility rules. Learn more. |

UI consistency review of the in-scope web changes (ComposerPromptEditor.tsx, settings/SettingsPanels.tsx, settings/settingsSearch.ts).
The new spellcheck UI reuses the shared primitives correctly (Switch for the row control, Checkbox inside a <label> matching the existing pairing-scope list in ConnectionsSettings.tsx, SettingResetButton, SettingsRow slots, theme tokens only, catalog-driven anchor id/title), and the composer only forwards spellCheck to the existing Lexical ContentEditable without touching its class contract. One spacing/geometry deviation from the SettingsRow children contract is noted inline.

CodeRabbit nitpick on |

Fixes #7742
What Changed
/etc/vconsole.confand/etc/default/keyboard.en-USfallback.Why
The packaged app can resolve to
en-USeven when the user types Portuguese or uses a Brazilian keyboard. Electron also treats an empty dictionary list asen-US, so simply clearing the list preserves the false-positive underlines. The app now resolves only supported dictionaries and fails closed when none match.Related: #2554 requested a disable toggle. #4254 enabled native composer underlines but did not configure their language.
UI Changes
Before: Appearance had no spelling control.
After:
The picker is populated from
session.availableSpellCheckerLanguages, so it reflects the Electron build instead of a truncated hardcoded list.Validation
