Hi. I hope I'm submitting this correctly; please tell me if I'm wrong. I'm
trying to at least prototype a GUI in the same way that in Python I can
write "import gi" and proceed to create a GTK window, add buttons and
menubars and toolbars, etc. I've tried the various online  sites, but none
of them have succeeded for me even with "use-modules", so I'm thinking
they've not been updated for Guile 3.0 yet. And that's fine; I understand
the massive effort involved. I would actually like to know if one of the
projects is slated to move forward, so I can volunteer to help. And I don't
care if that toolkit is for GTK or some other platform.

For my environment, I'm running guile 3.0.8 under the latest guix, and I've
done upgrades, but I admit to being a guix n00b. I have guix running atop
Ubuntu 22.04, if that's relevant.

I will assume that I should report my problems with guix installing the
various toolkit packages not here, but to a guix mailing list.

Finally, if there's no GUI toolkit for Guile coming anytime soon, then I
can write my app in C and link Guile into it. I've done the linking
successfully several times for other projects. But it would be really nice
to have a simple Guile script that launches a GUI, just as I can have a
simple Python script do the same. The rest of my app's code is in Guile
Scheme.

Thanks in advance, but I hope to follow up.

Hello,

I've tested making some basic GTK guis with the `guile-gi` package. It
might be worth taking a look at that. The project is located on
Github[1], it's also packaged for Gnu Guix.

Hope that helps.

Thanks,
Jessica.

Thank you, Jessica! That assurance is all I really needed, but FYI: When I
type "(use-modules (gi))" into an interactive guile, trying to follow
https://github.com/spk121/guile-gi/blob/master/examples/cairo.scm , guile
responds with:
While compiling expression:
no code for module (gi)

If you happen to know how to fix that, it'd be fantastic for me. But it
appears to me to be an issue with guix, so I'm happy to ask over there.

Or did you build the gi package from source? I can do that too, but I
prefer to just install a binary package when I can.

Thanks greatly again.

No problem.

I'm using it with guix, for example I can do:

$ guix shell guile guile-gi
$ guile
scheme@(guile-user)> (use-modules (gi))

Could it be that you've installed the guile-gi package with guix, but
it's using a system guile version which isn't set up to look for modules
in the path that guix is putting them in? I'm relatively new to guix so
if the above doesn't work, it's prehaps best asking over with the guix
folks since I'm relatively new to guix too.

You might also try G-Golf - disclaimer, I am the G-Golf maintainer, I
was hoping/waiting that some answer(s) would point to both solutions,
but as it didn't happen, here is the link [1].

Thank you both!!

Jessica, when I invoked the guix shell as you showed, it worked in that
"(use-modules (gi))" succeeded. I need to learn more about including
packages with the guix shell command. It's odd that I can get the latest
guile to run without specifying it for guix, but I must have the other
packages for gi to work .. . .

David, I was able to install G-Golf via guix, and that also worked with the
"use-modules" portion of your "Hello, World!" example.

HOWEVER (alas), both examples fail on the "use-typelibs" line, with:
Typelib file for namespace 'Gtk', version '4.0' not found

In trying to resolve that error myself, I found that the guile manual has
no entry for "use-typelib" in the Procedures Index. :-/  I'll submit that
bug in a new email, after confirming there's not already a thread.

Oh, and David, https://www.gnu.org/software/g-golf/index.html has a link
for Typelib that 404s. I would suggest a fix, but I couldn't easily find
one, sorry.

But both of you have shown me that what I originally wanted to do is, in
fact, doable. Thanks again!

This is a guix 'problem' [1], please try to get some help on guix-user
ML, or if you have on irc:	irc.libera.chat	(channel) #guix

No, there is no 'use-typelib, as you can read in each example, the
procedure call is:

	(g-irepository-require "Gtk" #:version "4.0")
	[ the manual has an entry for g-irepository-require

So, with this in mind, the error message is 'correct'. Note that it
would also fail if there is a tipo in the namespace, or if you refer to
a version that does not exist ...

Thanks, I'll look at this.

David

[1]	I mean you need to find the name of the package and install
it, this is not a G-Golf dependency, it is only needed if you wish t
run those examples, which are mini apps, not part of the G-Golf core
lib ... so to speak, it is 'user dependency' ... I think guix has Gtk-4+
packages, including the package that 'has' the typelib, but I don't use
guix, so i am unable to give you precise guidance ... the #guix channel
is extremely responsive, helpful, and very friendly, so don't be
scared to ask ...

Thank you greatly, David. I cleaned up my guix environment and reinstalled
G-Golf, and now the hello world script runs but hangs after these errors:

(g-golf-hello-world.scm:494347): GLib-GObject-WARNING **: 12:37:46.818:
cannot register existing type 'GdkPixbuf'

(g-golf-hello-world.scm:494347): GLib-GObject-CRITICAL **: 12:37:46.818:
g_type_add_interface_static: assertion 'G_TYPE_IS_INSTANTIATABLE
(instance_type)' failed

(g-golf-hello-world.scm:494347): GLib-GObject-CRITICAL **: 12:37:46.818:
g_type_add_interface_static: assertion 'G_TYPE_IS_INSTANTIATABLE

(g-golf-hello-world.scm:494347): GLib-CRITICAL **: 12:37:46.818:
g_once_init_leave: assertion 'result != 0' failed

So I assume I haven't fixed the guix environment completely yet, but I'm
still working on that. The guix toolset is advertised to manage all the
interdependencies, but I'm not certain that it works in every situation.
I'll keep trying, though. Thanks again.

Could you please show us how to reproduce this?  We would need to see
the Guix command, the code you run, and ideally the output of “guix
describe”.

Thank you for responding, Ricardo! I have tried several permutations of
packages, but currently I have this:

$ guix package --list-installed
guile       3.0.8             out
/gnu/store/1jgcbdzx2ss6xv59w55g3kr3x4935dfb-guile-3.0.8
gnutls       3.7.7             out
/gnu/store/349nw48785mbxzsl3adc4wch1hslg7fl-gnutls-3.7.7
guile-g-golf 0.1.0-1010.1824633 out
/gnu/store/vwkaxl1cl76yxdpzvkvx0sclkyksqm9g-guile-g-golf-0.1.0-1010.1824633

$ guix describe
Generation 2 Aug 21 2022 10:50:20 (current)
  guix 706b3ef
    repository URL: https://git.savannah.gnu.org/git/guix.git
    branch: master
    commit: 706b3ef38b2f7ce9f05aa56e2eaaaf1c19e25f90

With that, I run guix shell guile guile-g-golf . Within that shell, I run
the script found at
https://git.savannah.gnu.org/cgit/g-golf.git/tree/examples/gtk-4/hello-world.scm
,
and it produces those errors, and hangs.

I am a complete n00b with guix (and g-golf, but I have some history with
guile), so I'm assuming I'm doing things incorrectly. That's why I'm trying
permutations of package installs; I get the same errors with gtk 4.6.6
installed and included on the guix shell command. So I'm willing to try
whatever you suggest, to get this bug closed. My base OS is Ubuntu 22.04,
which only lets me install guile 3.0.7 via apt, and the other packages are
similarly out-of-date or broken - which is why I turned to guix. It has
done well on the other packages I've tried (gnutls, for one). So please
tell me if I can help in any way.

Hi,

This looks all right to me.

I can reproduce this.  I also tried the latest commit of g-golf:

    guix shell --pure guile \
                      guile-g-golf \
                      gtk@4 \
                      coreutils \
                      grep \
               --with-commit=guile-g-golf=b9956e6e4c60d6be5424290e4366f3d3f46b2c31 \
               --cores=1

No difference.

My first guess was that perhaps it gets confused because GTK 3 stuff
also exists on my machine, so I used “--pure” to overwrite the
environment variables.  I also tried “--container” to be sure it doesn’t
accidentally pick up incompatible stuff.

But I can’t get it to work.  It would be helpful if g-golf were to print
more diagnostic information.  As it is I cannot think of anything to
make it work.

I only ever used guile-gi successfully.  This is the Guix shell:

   guix shell --pure guile guile-gi gtk@4 -- guile gi-test.scm

And here’s the code in gi-test.scm:

--8<---------------cut here---------------start------------->8---
(use-modules (gi) (gi repository))

(require "Gio" "2.0")
(require "Gtk" "4.0")

(load-by-name "Gio" "Application") ;activate, run
(load-by-name "Gtk" "Application")
(load-by-name "Gtk" "ApplicationWindow")
(load-by-name "Gtk" "Button")
(load-by-name "Gtk" "Box")
(load-by-name "Gtk" "Window")
(load-by-name "Gtk" "Widget") ;present

(define (print-hello widget)
  (display "Hello World\n"))

(define (on-activate app)
  (let* ((window (make <GtkApplicationWindow>
                   #:application app
                   #:default-height 200
                   #:default-width 200
                   #:title "Window"))
         (box (make <GtkBox>))
         (button (make <GtkButton>
                   #:label "Hello world")))
    (set-child window box)
    (append box button)
    (connect button clicked print-hello)
    (present window)))

(define (main)
  (let ((app (make <GtkApplication> #:application-id "org.gtk.example")))
    (connect app activate on-activate)
    (run app (command-line))))

(main)
--8<---------------cut here---------------end--------------->8---

Clicking the button prints “Hello World” to the terminal.

This is a guix problem, reported a few years ago already by one of my
first g-golf user, the author of the nomad package. I have no idea why,
nor what it takes to fix this in guix, but this error is the symptom
that you (guix, not you nor g-golf) is trying to load the Gdk typelib
more then once, which is 'unauthorized', by (GNOME) design.

Until what causes this error is fixed, absolutely nothing can work.

I am on Debian, where all examples work [1]

> (g-golf-hello-world.scm:494347): GLib-GObject-CRITICAL **:
> 12:37:46.818: g_type_add_interface_static: assertion
> 'G_TYPE_IS_INSTANTIATABLE (instance_type)' failed

This is the symptom that you are running a g-golf version that was
built from the devel branch - where as this is generally ok, I am also
very cautious to what I push even on the devel branch, I am in a process
of re-designing re-writing the way users may register new classes, that
inherit from GInterface. I also am re-designing re-writing how users
interact with VFunc. For these reasons, I recommend the guix team
to stick to the latest commit of the master branch for now.

The hello-world example has worked 'fine', on Debian, for many years,
you don't need the latest commit to run it :) - though in January
2021, I updated it (as well as other examples) to use Gtk-4.0.

	I see Ricardo also answered and tried, I'll also comment his
	message(s) ...

David

[1]    in addition to what you need to install g-golf, to run the
examples, you also need to install gir1.2-gtk-4.0:amd64 (or 
gir1.2-gtk-4.0:xxxx  for another architecture, which content is listed
below, fwiw:

Hello Ricardo,

Thanks for your help on this  guix problem - G-Golf works perfectly
fine on Debian - See the first part of my answer to Lee's message,
the one that comments the GdkPixbuf bug that happens (only) on guix.

> My first guess was that perhaps it gets confused because GTK 3 stuff
> also exists on my machine

That is impossible, by GObject Introspection design, you may, as I

Oh, please stick to the latest  master commit -  I am in a process
of re-designing re-writing the way users may register new classes, that
inherit from GInterface. I also am re-designing re-writing how users
interact with VFunc. For these reasons, I recommend the guix team
to stick to the latest commit of the master branch for now.

The hello-world example has worked 'fine', on Debian, for many years,
you don't need the latest commit to run it :) - though in January
2021, I updated it (as well as other examples) to use Gtk-4.0.

These are Gtk/Gdk/GObject/GLib error messages, not G-Golf messages, as
there is no G-Golf error here.

Glad to here that.

In debian, after you compiled installed G-Golf, and the
gir1.2-gtk-4.0:amd64, you may

	cd <...g-golf...>/examples/gtk-4
	./hello-world.scm

	[ or any other examples
	[ for the revealer.scm though, you need to make sure the
	[GNOME] desktop 'animation' option is ON

Thanks again, David. I was able to use a solution from Ricardo to get
guile-gi to run under guix, but it didn't work for g-golf. :-( Even so, I
was serious about wanting to help you out. My Ubuntu system has guile
3.0.7, which I hope would be OK. For g-golf, would you recommend I clone
your github repo and compile it . . . ? I can give that a try. I'm not
entirely sure that packages installed by guix won't interfere, and I don't
yet know how to uninstall guix, but I'll give it my best shot for you.

Guix doesn’t install anything globally where other libraries would look
for stuff, so it doesn’t interfere with anything on the system.

For the record: what fixed the remaining problems with guile-gi was
running the code under dbus-launch.

Hello Lee,

Welcome.

I hope Ricardo, possibly with the help of other guix contributor's will
find a solution so that g-golf may also run 'out of the box' on guix.

> guile 3.0.7, which I hope would be OK.

Yes, you need guile 2.0, 2.2 or 3.0, in which case it must be >= 3.0.7

> For g-golf, would you > recommend I clone your github repo and

Yes, installing from the source tree instructions are here:

	https://www.gnu.org/software/g-golf/install.html

	[ just 'stick' to the master branch, although I may recommend
	[ to use the devel branch 'in the future', at this moment the
	[ devel branch is in a wip stage.

Two things to add to those instructions:

1.
	to run the checks, 'make check', you'd need two additional
	dependencies:

		gir1.2-clutter-1.0:amd64
		gir1.2-gtk-3.0:amd64

	I'll get rid of those dependencies before the first official
	release, but for now, some tests use either clutter or gtk-3

2.

	to run g-golf examples, you need to install

		gir1.2-gtk-4.0:amd64

	you may try the examples before installing, like this:

	cd  <...g-golf-tree...>/examples/gtk-4
	../../pre-inst-env ./hello-world.scm

This page shows a screenshot for each example:

	https://www.gnu.org/software/g-golf/learn.html

Let me kow how it goes,
Thanks,
David

Thank you again, David. I followed your installation instructions, and with
a few warnings, your hello-world example (eventually) ran. I can submit
what I saw to the bug-g-golf@gnu.org address.

I also got clipboard.scm to run, with one error.

I think for Jessica's and Ricardo's sakes, and because it's the right thing
to do, we can close bug #57379 and carry on elsewhere.

Turns out that it all works fine when you disable grafts:

  guix shell --pure --no-grafts \
    guile guile-g-golf gtk@4

This echoes a discussion here:

  https://github.com/spk121/guile-gi/issues/96

The immediate lessons from the observations detailed in this issue are
also why guile-gi works without disabling grafts.

Hi Lee,

Great. What do you mean by '(eventually) ran'? Everything works fine,
'out of the box' and with no warnings, on debian ...

> can submit what I saw to the bug-g-golf@gnu.org address.

No, please don't report warnings on bug-g-golf@gnu.org, rather, use the
guile-user ML, prefixing all g-golf related messages using 'G-Golf - ',
as proposed here  https://www.gnu.org/software/g-golf/contact.html

> I also got clipboard.scm to run, with one error.

	afaict, all examples should work fine, with no warning(s) and no
	error(s)

Please post a (separate) guile-user ML email with the error, as there is
no error nor any warning here (debian testing), I'd need to see ...

You should definitely close bug#57379, which shouldn't have been opened
in the first place: it was not a guile nor a g-golf bug in the first
place ...

I invite you to report the warning(s) and bug(s) in separate
guile-user ML email(s) - start a new thread for every diff subject,
let's not mix things and examples ... also, why don't you join us on
irc.libera.chat as well, both #guile and #guix (which I follow but I do
not participate, unless g-golf, guile-lib ... related, only wrt those
packages I am involved in ...)

I can confirm that disabling grafts allows both of the g-golf examples to
run, and they come up quickly. I suspect they were slow due to something
in the grafts; I'll find out. I still get some errors, but they also appear
to be related to guix. I'll read the discussion.

Thank you, Ricardo!

So what I meant by "eventually", David, is that the apps were slow to
appear. Without the grafts, now they aren't.

I sincerely apologize for opening a bug on the original issue; it appeared
to be the right thing to do at the time. I am trying to get some apps built
in Guile, and sometimes it is difficult to find information. Plus, I am
dying from cancer, so many times my brain is not as lucid as I need it to
be, so I make social errors. But I do apologize, and I will do better in
the future.

It's not obvious to me how I can close this bug report. I will try to find
out, but if you have a quick response, I would appreciate it.

I feel you don't need to apologize

With some GNU people, you're never enough

You're not enough smart, you're lazy, you don't want to read the
manual, you don't wanna do you homework, you want to parasiticly
leverage other people's free time

The hypothesis that the problem is in the defect if their communication
is religiously rejected a priori

In fact I run into the same error some years ago and I was berated for
that

You can feel assured it's not your fault

That's another religious thing of some communities
