Hi!

I've defined a minimal GNOME this way:

--8<---------------cut here---------------start------------->8---
(define-public gnome-minimal
  (package
    (inherit gnome)
    (name "gnome-minimal")
    (propagated-inputs
     ;; Keep nautilus.
     (fold alist-delete (package-propagated-inputs gnome)
           '("baobab"
             "cheese"
             "eog"
             "epiphany"
             "evince"                   
             "file-roller"
             "gedit"
             "gnome-boxes"
             "gnome-calculator"
             "gnome-calendar"
             "gnome-characters"
             "gnome-clocks"
             "gnome-contacts"
             "gnome-disk-utility"
             "gnome-font-viewer"
             "gnome-maps"
             ;; "gnome-music"
             ;; "gnome-photos"
             "gnome-screenshot"
             "gnome-system-monitor"
             "gnome-terminal"
             "gnome-weather"
             "simple-scan"
             "totem")))))
--8<---------------cut here---------------end--------------->8---

Then I modified my GNOME service:

--8<---------------cut here---------------start------------->8---
(operating-system
 ...
 (services (cons* (service gnome-desktop-service-type
                             (gnome-desktop-configuration
                              (gnome gnome-minimal)))
                    %my/services))
--8<---------------cut here---------------end--------------->8---

But building it fails with

--8<---------------cut here---------------start------------->8---
Backtrace:
           1 (primitive-load "/home/ambrevar/.config/guix/current/bin/guix")
In guix/ui.scm:
  1945:12  0 (run-guix-command _ . _)

guix/ui.scm:1945:12: In procedure run-guix-command:
Throw to key `match-error' with args `("match" "no matching pattern" #f)'.
--8<---------------cut here---------------end--------------->8---

Any idea?

As a side note, would it make sense to include it in Guix?
Maybe just include the above example in the documentation?

Cheers!

So this is basically a plain Gnome shell withouth any programms? What is
the use-case for it?

s/without any programmes/with the programmes you actually choose 
to install/

‘gnome-desktop’ is a maximal beast, and is only going to get more 
so as Raghav's work progresses.  I don't think Guix should ship a 
‘gnome-minimal’ package (nor am I fiercely opposed), but it makes 
sense to modify things like gnome-polkit-settings to handle only 
keys that are actually present and ignore #f.

I presume that's what Pierre is doing right now; we'll see :-)

Kind regards,

Thanks, Tobias!

The definition below builds in a system, I haven't tried booting it yet:

It saves close to 500 MiB in the closure size!  Not bad :)

Hi Pierre,

Do you consider gnome-keyring to be a part of gnome-minimal? If you do, gcr -
gnome keyring prompter should also be added.

I would say yes, but that's debatable of course :p

Are you saying the gnome-keyring won't work without gcr?  Why?

I think it will, with some low level stuff, but I couldn't use it or even unlock it. Maybe there are other SystemPromters out there.

Looks like a bug in our gnome-keyring package definition.
Could you file this issue at bug-guix@gnu.org?

Just tried it, it works!
But Evince remains pulled in, I suspect because of gnome-default-applications.

Jonathan: I didn't receive your emails (not the first time), only
Tobias' quote.

My personal use-case: I use EXWM most of the times, but it's nice to
have an extra desktop environment for:

- Testing software in a different environment, e.g. XDG integration,
  etc.
- Making FOSDEM presentations :)  (Works for other presentations too!)
- Letting non-techie friends use my system.

For the above I don't need any GNOME program but GNOME shell and Nautilus.

A lighter system has the benefits of:

- being easier on Internet bandwidth,
- updating faster.

Cheers!

And obviously lighter and disk space! ;)

My immediate thought is: #f is what (assoc-ref l 
"non-existent-thing") returns.

And indeed:

(define (gnome-polkit-settings config)
  "Return the list of GNOME dependencies that provide polkit 
  actions and
rules."
  (let ((gnome (gnome-package config)))
    (map (lambda (name)
           ((package-direct-input-selector name) gnome))
         '("gnome-settings-daemon"
           "gnome-control-center"
           "gnome-system-monitor"
           "gvfs"))))


You need to include gnome-system-monitor, or adjust the service 
too.

Kind regards,

T G-R
