Guix Shepherd Service Help

Guix Shepherd Service Help

[samuel]

Hello, I'm new to Guix (About five or so days?), right now I'm 
attempting to make a service for udevmon (interception-tools) so that I 
can use caps2esc (I've already defined that package in my channel) so 
that I don't get Emacs pinky 😄. However, I'm running into one issue... I 
can get the service to launch the program, even with parameters, but it 
seems that even hard-coded paths don't work inside of the configuration 
yaml.

Service file: 
https://github.com/chubbymomo/momo-channel/blob/main/momo/services/udevmon.scm

Relevant snippet of log: 2024-01-18 20:50:47 an exception occurred: 
"exec failed for devnode /dev/input/event10, job 
"/run/current-system/profile/bin/intercept -g $DEVNODE | 
/run/current-system/profile/bin/caps2esc | 
/run/current-system/profile/bin/uinput -d $DEVNODE" with error "No such 
file or directory""

Any help would be nice, I've been smashing my head into the wall for a 
few days as I feel this is required for my usage of Emacs. I'm not sure 
why anyone would want this, but the relevant channels.scm snippet will 
be in the readme.md of the same repository. I'm not entirely sure why it 
doesn't work, running the command by hand using sudo just works. Would 
somehow "dynamically" creating the yaml with path included work? I would 
prefer if there could be preservation of using a yaml that isn't 
statically generated.

I can't help you with the service issue, but if you're running Guix 
System take a look at `keyboard-layout`. i.e. (keyboard-layout "us" 
#:options '("ctrl:nocaps"))

Hi Samuel,

Personally, I would create the configuration file via serializers in
'define-configuration'. It would allow you to use the store paths that
come from package variables instead of paths into the system profile.

It's a bit involved, but works great from then on out.

Kind regards
