This PR adds French formula localization and fixes menus that remained in English despite the selected interface language.

Adds French Excel names for all 514 recognized function names, including names that remain unchanged in French.

Supports French formula entry, display, autocomplete and insertion, with decimal commas and semicolon argument separators.

Preserves canonical English syntax for stored formulas, XLSX files and engine/API calls.

Connects macOS native menus to the existing translation catalog at startup and when the interface language changes. This benefits every supported language where translations exist.

Adds 69 missing French menu labels and localizes the quick-access commands menu.

The implementation reuses the existing localization infrastructure. Formula help text and parameter descriptions retain their existing language fallback.

Validation: all eight cargo xtask ci checks passed, including tests and WebAssembly. Added coverage checks formula round trips, XLSX persistence, autocomplete, and live French/English switching of the actual macOS menus through AppKit.

Summary by CodeRabbit

  • New Features
    • Enter and view formulas using French function names, separators, and boolean values. French supports all 514 registered function names, while formulas remain stored in canonical form.
    • Native macOS menus and the quick-access menu now show translated labels. Menu text updates when you change the app language, without changing commands or shortcuts.
    • Added translations for the distinct Edit menu label across supported languages.
  • Documentation
    • Updated formula and localization guides to describe French formula support and language behavior.

Walkthrough

The pull request adds French formula parsing and display, expands French interface translations, and localizes quick-access and native macOS menus. Formula storage remains canonical English. Native menu labels refresh when the interface language changes.

Merge Risk: Low · up to e8c33

After switching languages, macOS menu labels may remain in the previous language until another interaction. This is bounded and does not prevent merging, but should be fixed.

Security architecture risk: Low · up to e8c33

The reviewed paths preserve canonical saved formulas, retain the original language of pending edits, and update menu labels without changing command identities. No introduced security vulnerability was established. Remaining uncertainty limits assurance beyond those paths.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

  • inferred — The demonstrated new exposure is French syntax entering the existing workbook formula path. Inspected API and file consumers do not inherit locale-dependent parsing; native menu translation changes presentation rather than the set of dispatchable commands.

Trust Boundaries and Controls

  • observed — Translated menu text is not used as command authority. Items retain their original IDs, relabeling calls set_text on existing handles, and event handling dispatches by event ID through the existing clipboard, dialog, URL and command routes.

Resilience and Maintainability Implications

  • inferred — Separating interface language, pending-edit locale and canonical workbook state contains localization failures at the presentation/input boundary. The inspected failure branches preserve retry state rather than silently committing text under a newly selected locale.

@NaviStorm I verified commit 3bbeec3. It adds English doc comments to all 11 functions and makes no behavior changes.

Using the previous check’s scope of 45 functions, coverage should increase from 27/45 (60.00%) to 38/45 (84.44%). This exceeds the 80.00% threshold.

The published check still shows 60.00%, so the automated result remains unconfirmed. I’ll trigger a review to recheck coverage.

🟡 Minor · Refresh the native menu after the UI pass. · main.rs:35-40

apps/gridcraft/src/main.rs:35-40
🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Refresh the native menu after the UI pass.

On macOS, NativeMenu::poll runs before SheetApp::ui. The language ComboBox writes app.ui.language during SheetApp::ui, so that poll sees the old language. The default CloseOnClick popup closes its stored state but does not request another repaint. Native labels can therefore remain stale until another repaint-triggering event.

Poll the menu after self.0.ui(ui) so labels update in the same frame.

Suggested fix
     fn ui(&mut self, ui: &mut egui::Ui, _frame: &mut eframe::Frame) {
         self.0.ui(ui);
+        #[cfg(target_os = "macos")]
+        if let Some(m) = &mut self.1 {
+            m.poll(&mut self.0, ui.ctx());
+        }

Fixed in commit 75f9a58.

Native macOS menus now refresh immediately after SheetApp::ui, so language changes take effect without waiting for another input event.

I also incorporated changes from @Titoun12’s #2310 : corrected MAX.SI.ENS/MIN.SI.ENS names, French error literals in formulas, and the test checking function-name coverage and uniqueness. Thanks @Titoun12!

All 8 CI checks pass, including the AppKit menu localization test.

Hi NaviStorm,

I wanted to share the results of the French Excel testing I contributed earlier, in case they're useful when integrating the French dialect into the new structure introduced by #1522.

I tested French function names and formula behavior in both Excel 2013 and Excel 2024, including how changing only the Windows regional format affects argument and decimal separators, array constants, and "TEXTE" format codes.

You can find the earlier test results here:

For example, with the French regional format, "=SOMME(1,5;2)" returns "3,5", and "=TEXTE(DATE(2026;3;15);"jj/mm/aaaa")" returns "15/03/2026", while the equivalent "dd/mm/yyyy" format returns "#VALEUR!".

I hope these real-world Excel results are helpful when validating the French implementation. Thanks for your work on this!
