Wayland doesn't support Global Shortcuts and panics

[manuel-minniti]

I managed to get a basic environment running on NixOS (nix 2.13.6).

System info

$ nixos-version
23.05.5533.70bdadeb94ff (Stoat)

I simply put my nix-shell (see below) into the project directory and ran nix-shell.

Problem

Running bun run tauri build:

bun run tauri build
$ tauri build
     Running beforeBuildCommand `mkdir -p dist`
    Finished release [optimized] target(s) in 0.15s

       Error failed to bundle project: error running appimage.sh
error: script "tauri" exited with code 1 (SIGHUP)

Running bun run tauri dev:

bun run tauri dev
$ tauri dev
     Running BeforeDevCommand (`mkdir -p dist`)

Example nix-shell

let
  pkgs = import (fetchTarball("https://github.com/NixOS/nixpkgs/archive/057f9aecfb71c4437d2b27d3323df7f93c010b7e.tar.gz")) {};

  libraries = with pkgs;[
    bun
    cargo
    ollama
    rustc
    xorg.libXtst
    xdotool
    libayatana-appindicator

    webkitgtk
    gtk3
    cairo
    gdk-pixbuf
    glib
    dbus
  ];

  packages = with pkgs; [
    bun
    cargo
    ollama
    rustc
    xorg.libXtst
    xdotool
    libayatana-appindicator

    pkg-config
    dbus
    glib

    libsoup
    webkitgtk
    appimagekit
  ];
in
pkgs.mkShell {
  buildInputs = packages;

  shellHook =
    ''
      export LD_LIBRARY_PATH=${pkgs.lib.makeLibraryPath libraries}:$LD_LIBRARY_PATH
      export XDG_DATA_DIRS=${pkgs.gsettings-desktop-schemas}/share/gsettings-schemas/${pkgs.gsettings-desktop-schemas.name}:${pkgs.gtk3}/share/gsettings-schemas/${pkgs.gtk3.name}:$XDG_DATA_DIRS
    '';
}

Unable to register global shortcut - can you try modifying the shortcut? make it something like Ctrl+Shift+. and Ctrl+Shift+/ instead and see if it works?

Might want to pull main first as this is way easier now with the settings.json.

@manuel-minniti - lmk if fixed!

[manuel-minniti]

Thanks for the quick reply, I'll let you know!

[manuel-minniti]

Still getting the same error unfortunately.

thread 'main' panicked at src/main.rs:148:18: Failed to register global shortcut: GlobalShortcut(InvalidAccelerator("Unable to register global shortcut"))

Is there a way to get a more verbose error message?

[jasonjmcghee]

You can run with RUST_BACKTRACE=1

Are you running Wayland?

If so... https://github.com/tauri-apps/global-hotkey/issues/28

[manuel-minniti]

RUST_BACKTRACE=1 did not really tell me much.

Yes, I am using Wayland and I have since upgraded NixOS to 24.05 (Uakari).

[jasonjmcghee]

Alright. I think we'll need to figure out a workaround for Wayland... as tauri doesn't support it yet for global shortcuts and it causes a panic.

[jasonjmcghee]

Every hotkey library I've found does not support Wayland. Also found this- relatively interesting https://gist.github.com/probonopd/9feb7c20257af5dd915e3a9f2d1f2277

Next best thing seems like manually parsing the accelerator and monitoring "pressed_keys" for the shortcut we're looking for
