GNOME/Calendar
The Gnome calendar is the desktop calendar application built into GNOME.
Using Gnome Calendar outside of GNOME
To use the gnome calendar outside of gnome, you need the following lines in your configuration.nix:
{
programs.dconf.enable = true;
services.gnome.evolution-data-server.enable = true;
# optional to use google/nextcloud calendar
services.gnome.gnome-online-accounts.enable = true;
# optional to use google/nextcloud calendar
services.gnome.gnome-keyring.enable = true;
}
External calendar such as google/nextcloud can be only added via the gnome-control-center:
$ nix-shell -p gnome.gnome-control-center --run "gnome-control-center"
then add your accounts in the "Online Accounts" submenu.
If gnome-control-center will not launch, it's possible the value of XDG_CURRENT_DESKTOP needs to be changed to GNOME during launch. This is the case when using the Hyprland window manager.
$ XDG_CURRENT_DESKTOP=GNOME gnome-control-center
This should launch gnome-control-center and allow you to access the Online Accounts submenu.
To get alarm reminders you need to start the evolution-alarm-notify daemon provided by the gnome.evolution-data-server
package. When you enable services.gnome.evolution-data-server.enable
it will add a desktop autostart entry to /run/current-system/sw/etc/xdg/autostart/org.gnome.Evolution-alarm-notify.desktop
. If your desktop manager does not process autostart entries, you can use dex instead:
$ dex --autostart
As an alternative you can start libexec/evolution-data-server/evolution-alarm-notify
from the gnome.evolution-data-server
directly.
