Fixes #6176.

While a file panel is in use, the menu bar is swapped for a small one. It has an Edit menu (Cut, Copy, Paste and Select All, muda's predefined items with the usual shortcuts) and an application menu with Hide, Hide Others and Show All. Quit is left out until the panel closes. The usual menu bar returns when the panel closes, and also if the code showing the panel panics. Outside the panels, WordCraft's own text boxes still get these keys from egui.

WordCraft has one window per document, and the panel is a sheet on one of them. The small menu bar shows only while the key window is that panel or a sheet on it, such as Go to Folder (in a window of its own). Another document's window keeps the usual menu bar and its shortcuts.

file_dialogs.rs counts the open dialogs with a Drop guard, so a dialog whose thread panics is no longer counted, and the launcher checks the key window every 250 ms while a dialog is open. If the app installs a new menu bar while the panel's is showing, the new one is kept.

New dependency: muda 0.21 with default features off (Apache-2.0 OR MIT). It makes the AppKit calls, so the code needs no unsafe.

Tests:

  • New mac_panel_menu_appkit test (macOS, harness = false; it answers nextest's --list request, so nextest can list it). It checks that ⌘X, ⌘C, ⌘V, ⌘A and ⌘H send cut:, copy:, paste:, selectAll: and hide:, that there is no Quit, that nothing is swapped while no panel is key, and that an NSSavePanel counts as a file panel while a colour panel does not. It also checks that a menu bar installed while the panel's is showing stays when the panel closes, and comes back after the panel's if the panel is still key. It fails without the key-window check, without the Hide item, and without either rule for a menu bar installed meanwhile. The step from Go to Folder up to its panel was checked by hand (below).
  • A unit test in file_dialogs.rs checks that a dialog whose waiting thread panics is no longer counted.
  • By hand on macOS 27.3 (M1): ⌘O, ⌘⇧G, ⌘V pastes the path with this branch. It does nothing with the 0.17.0 release. The Edit menu stays while Go to Folder is open. With two documents and a panel on one, the other window has the usual menu bar, and the panel's menu bar returns when the panel's window is key again.
  • Every step of cargo xtask ci, run locally on macOS 27.3 with cargo-nextest 0.9.150 and cargo-deny 0.20.2, passes except 20 tests that fail the same way on main on this machine, which lacks the fonts and hyphenation data they need. Windows and Linux: left to CI.

PRs with the same fix in the other apps: storytold/deckcraft#2007, storytold/gridcraft#3683, storytold/pdfcraft#6817.

Summary by CodeRabbit

  • New Features
    • On macOS, file panels now show the standard Cut, Copy, Paste, and Select All commands with their keyboard shortcuts. The app’s usual menu bar returns when the panel closes.
  • Bug Fixes
    • The interface now refreshes while a file dialog is open and when it finishes, including if its background wait ends unexpectedly. The menu bar is left unchanged if another menu replaces the panel menu while the dialog is open.

…ls (storytold#6176)

AppKit routes these shortcuts through the menu bar, so with no Edit menu
item for them the Go to Folder and file name boxes ignored them. While a
file panel is showing, a small menu bar with a standard Edit menu stands
in, and the usual one comes back when the panel closes.

Walkthrough

On macOS, WordCraft tracks open file dialogs and installs a temporary menu with standard editing actions while a file panel is active. It restores the previous menu when the panel closes. An AppKit test checks the menu actions, panel detection, and menu restoration.

Changes: File panel shortcut menu

Layer / File(s) Summary
Dialog lifecycle synchronization
apps/wordcraft/src/file_dialogs.rs, apps/wordcraft/src/main.rs
Tracks open dialogs with a shared counter. A guard decrements the count and requests a repaint when the dialog thread ends, including during a panic. On macOS, the launcher synchronizes the panel menu with the dialog count and requests another repaint while a dialog remains open.
Temporary AppKit menu and verification
apps/wordcraft/Cargo.toml, apps/wordcraft/src/panel_menu.rs, apps/wordcraft/tests/mac_panel_menu_appkit.rs
Adds a temporary menu with Cut, Copy, Paste, and Select All actions. File-panel detection and menu restoration are tested, including the case where another menu is installed while the panel menu is shown.

Estimated code review effort: 2 (Simple) | ~15 minutes

This change adds a temporary Edit menu so Cut, Copy, Paste and Select All work in macOS Open and Save panels, and restores the usual menu afterward. No merge-blocking risk was identified.

Explanation

The title names the main change: Cut, Copy, Paste and Select All now work in the macOS Open and Save panels. The changeset adds a temporary macOS panel menu bar with Edit items (Cut, Copy, Paste, Select All) that is shown while a file panel is active, which matches the title.

Full details: Linked Issues check

Explanation

Issue #6176 requires ⌘V (and ⌘C, ⌘X, ⌘A) to work in the Open panel's Go to Folder box on macOS. The raw summary shows panel_menu.rs installs an Edit menu with predefined Cut, Copy, Paste and Select All items while a file panel is key. in_file_panel walks up to eight sheet-parent or parent-window links to find an NSSavePanel. This covers Go to Folder, which is a sheet on the panel. file_dialogs.rs tracks open dialogs with a Drop guard and synchronizes the menu on each Launcher::show. mac_panel_menu_appkit.rs checks the key equivalents, the absence of Quit, panel detection, and menu restoration. The current PR description reports a manual check of ⌘V in Go to Folder on macOS 27.3. The changes implement the coding requirement. The manual check is non-coding and is not a basis for this verdict. Evidence comes from the summary only; no source inspection was made.

Full details: Out of Scope Changes check

Explanation

All changed files support issue #6176. panel_menu.rs and its macOS-only module declaration add the temporary Edit and application menu. file_dialogs.rs adds the dialog counter, panic-safe guard, and repaint timer that drive the menu swap. Cargo.toml adds muda with default features off and the AppKit features needed by the new code and its test target. mac_panel_menu_appkit.rs tests the new behavior. The Hide, Hide Others and Show All items are part of the same menu the issue's fix introduces. The Cargo.lock change is ignored and was not reviewed. No unrelated change is identified in the summary.

A guard holds the count from the request until the thread ends, a panic
included, so the panel's menu bar can't outlive the panel (macOS).

0606f46 counts an open dialog with a guard, so a waiting thread that panics no longer leaves the panel's menu bar up. Unit test added; checked again by hand on macOS.

nextest asks a harness = false test binary for its tests before running
them; the test ran instead and nextest refused the output on macOS.
Another document's window keeps ⌘X/⌘C/⌘V/⌘A while a panel is open on
the first, and its application menu has Hide, Hide Others and Show All.
A menu bar installed while the panel's is up is kept.
Go to Folder and New Folder are sheets on the panel, in a window of
their own, so the key window is checked together with the windows it
is a sheet or child of.

Updated after another review. The panel's menu bar now shows only while the key window is the panel or Go to Folder, so another document's window keeps its shortcuts. Its application menu has Hide, Hide Others and Show All, with no Quit while a panel is up. A menu bar installed meanwhile is kept, and the AppKit test now answers nextest's --list, which cargo xtask ci needs on macOS. The description lists what ran.

Keeps both sides in file_dialogs.rs: the Linux portal cancel handle from main and the
count of open dialogs. The count's guard asks for the repaint when the dialog thread
ends, so the separate repaint after the answer is gone. Arc is now imported on every
target.
