Development

In order to activate/deactivate a given extension, the project folder must be placed in the gnome-shell extension directory:

/home/$USER/.local/share/gnome-shell/extensions/

...or globally:

/usr/share/gnome-shell/extensions/

When developing you can clone this project to somewhere under your home directory, and then create symlinks in there to avoid copying the given project-folder from your workspace to the gnome-shell extension folder each time you make change, e.g. like so:

ln -s /home/$USER/<workspace>/os2borgerpc-gnome-extensions/logout_timer@os2borgerpc.magenta.dk /home/$USER/.local/share/gnome-shell/extensions/

For this we've created a justfile containing various commands, some of which you need to re-run each time you create a new extension project folder. Read more about just here.

To install all extensions in the repo via just:

just install-all

To install a specific extension from the repo:

just install logout_timer@os2borgerpc.magenta.dk

NOTE THAT in order to see changes you've made to the code, you need to reload the extension.

"Extensions can not be unloaded from a running instance of GNOME Shell. This can make testing incremental changes tedious. The most convenient way to test incremental changes, especially for Wayland users, is by running a nested instance of GNOME Shell. Running the following command from a terminal will start a new gnome-shell process, with its own D-Bus session:"

The justfile has a command for that:

just restart-child-gnome-shell
