Hello, I'm trying to use the `home-state-service-type' in my home
config, but it is not working for me. When I try to init the state I get
the following error:

--8<---------------cut here---------------start------------->8---
Initializing state-/home/lars/stumpwm.
herd: error: exception caught while executing 'unchecked-init' on service 'state-/home/lars/stumpwm':
In procedure module-lookup: Unbound variable: open-pipe-with-stderr
--8<---------------cut here---------------end--------------->8---

I saw another thread on the list with this exact same error from last
year with no resolution yet. Is `home-state-service-type` abandoned/not
working?

This is the relevant part of my home config:

--8<---------------cut here---------------start------------->8---
   (service home-state-service-type
            (list (state-git "/home/lars/stumpwm"
                             "https://github.com/stumpwm/stumpwm")))
--8<---------------cut here---------------end--------------->8---

Which is, as far as I can tell, exactly how it is done in your video.

Hello Lars!

I didn't touch this code for a long time and have long standing plan to
refactor or rewrite it.  I was busy with Arei (Guile Scheme IDE) and a
few more other things lately, but I regulary think and write some
related notes and snippets in local draft of (rde state), this question
also often bothers me, so I will get to it ASAP, but not earlier :)

I don't recommend to use "home-services" version of
home-state-service-type, but you can try to fix it if you want, the
solution probably is to add a module (guix build utils) to init gexp.

Don't hesitate to ping me from time to time on IRC or here about state
managment and related questions.

Is there another way I could use it? I have seen that there is something
called a `feature` in rde, but I'm not really using the full rde, I just
have a regular Guix setup with rde added as a channel (for now I only
added it to use the state service).

I already tried that, but it didn't help. I added a
`with-imported-modules` around the gexp, and added a `use-modules`
inside it but I still get the same error (which is very strange I think).

Thanks, will do!

The other version of state home service is not implemented yet, so no,
not at the moment :)

You've probably not had any time to look at this yet, but I thought I'd
give you a little ping to check just in case.

In the meantime I made a quick and dirty replacement for the service
which has done the job adequately for me for now. Posting it here in
case it could be useful for others:


(define (clone lst)
    (with-imported-modules '((guix build utils))
      #~(begin
          (use-modules (guix build utils))
          (for-each (lambda (it)
                      (let ((url (car it))
                            (target (string-append #$(getenv "HOME") "/"
                                                   (cadr it))))

                        (mkdir-p target)
                        (system* #$(file-append git "/bin/git") "clone" url target)))
                    '#$lst))))

(define-public home-git-clone-service-type
  (service-type
   (name 'git-clone)
   (extensions
    (list (service-extension home-activation-service-type
                             clone)))
   (default-value '(()))
   (description
    "")))

Thank you for updates!  I have a couple projects, which would benifit
from state management, however still have not enough resources to
properly design and implement it :)
