home-service-dwl-guile VS dotfiles

I think a good place to start looking for inspiration is dwl-guile. I tested this out a couple months ago and the way it wants to work is similar to what you're describing at least for the window management side of it. By setting up wofi as my launcher to be triggered with s-d I had a functional desktop that could launch apps. The rest of the config was a matter of setting up pipewire, pipewire-pulse, and swaybg as home services to also be triggered on login to that user. There may be more trickery involved but I recall burning out and abandoning it due to foot crashing the whole desktop.

I think it's beneficial to write these files in the normal way and then just add them to the store with simple home-services through local-file (plain-file is ok too but messier in my opinion). Its easier to understand, removes a point of failure in the scheme configuration -> normal configuration step, portable, "immutable", and it allows you to collect them all into one nice dotfiles repo. Here's mine for an example: https://github.com/Tass0sm/dotfiles/tree/master/home/files

I use Guix Home for managing my dotfiles on Arch Linux. I think its pretty fun but its not totally perfect. This config also isn't totally reproducible. Here's the link for that repository: https://github.com/Tass0sm/dotfiles
