[feature request] option to create .desktop file

[davidstaudt]

For best Linux desktop integration, the app should offer to (or have an option to) create a .desktop launcher file, per https://specifications.freedesktop.org/desktop-entry-spec/latest/

Currently, running Voice-Desktop-1.2.8-Ubuntu.AppImage (on Ubuntu 21.10/Xorg), the dock shows the application's icon, I assume based on 64px-Google_Voice_icon_(2020).png. However, right-clicking the running app icon in the dock, the 'Add to Favorites' option is not present. Additionally, the app cannot be discovered using dash search.

By generating/installing a voice-desktop-app.desktop file and associated icon file, dash search as well as 'Add to Favorites' works as do other/native apps:

Needed items:

• In $HOME/.local/share/applications/, create a voice-desktop-app.desktop file. Example contents:

  #!/usr/bin/env xdg-open
  [Desktop Entry]
  Type=Application
  Version=1.0
  Name=Voice Desktop App
  Icon=voice-desktop-app
  Exec=/home/user/opt/voice-desktop-app/Voice-Desktop-1.2.8-Ubuntu.AppImage
  Path=/home/user/opt/voice-desktop-app
  Terminal=false
  Categories=Network;InstantMessaging;Telephony
  StartupWMClass=voice-desktop-app

  Note: Exec and Path paths must be full paths, and would need to be computed at install-time based on the app's current working directory/filename

• Install a 48x48-resized version of 64px-Google_Voice_icon_(2020).png as voice-desktop-app.png into $HOME/.local/share/icons/hicolor/48x48/apps/
