Hi Folks,
I have a small Python script that sends me desktop notifications
to help
remind me to stop staring at the screen and go to bed on time. I'd
like to
turn it into a Guix home service, but I'm struggling and would
love some
advice.
Source for package, service and example home config is here:
https://git.sr.ht/~sturm/bedtime/tree
I can run the script like this, which works fine:
$ guix shell libnotify python python-pygobject dbus -- python3
-u bedtime.py
I've added a package "bedtime" in bedtime.scm. That works fine
too:
$ guix shell -L . bedtime -- python3 -u bedtime.py
For what it's worth, both these commands fail if I add
--pure. This seems like a
potential issue:
$ guix shell libnotify python python-pygobject dbus -- python3
-u bedtime.py
Traceback (most recent call last):
...
File "/home/ben/repos/bedtime/bedtime.py", line 47, in
notify_of_bedtime
Notify.Notification.new("Starting bedtime reminder").show()

I've tried to create an initial Guix home service
"home-bedtime-service-type" in
bedtime.scm. I can install this with `guix home` but it seems to
fail, unable to
find the dependency python-pygobject (gi):
$ guix home reconfigure -L . home-example.scm
$ herd enable bedtime
$ herd start bedtime
$ tail -f ~/.local/state/shepherd/bedtime.log
