pacman hook for electron on wayland

README.md

Electron 12 introduced early Wayland support behind the flags --enable-features=UseOzonePlatform --ozone-platform=wayland.

This gist adds these flags to the .desktop files of the selected Electron packages after every upgrade, so that they can be started from a launcher with Wayland enabled.

Will be deprecated after Electron eventually starts with Wayland by default without needing these flags.

Usage

1. Copy electron-wayland.sh to /usr/local/sbin/electron-wayland.sh
2. Add execution permissions to /usr/local/sbin/electron-wayland.sh (sudo chmod a+x /usr/local/sbin/electron-wayland.sh)
3. Copy electron-wayland.hook to /etc/pacman.d/hooks/electron-wayland.hook
4. Update electron-wayland.hook with the Electron packages you'd like to patch automatically

If you save electron-wayland.sh elsewhere, please update Exec in electron-wayland.hook correspondingly

_You may need to create the /etc/pacman.d/hooks/ folder first``
