Wow, congrats!  And thanks!

I've created a package description for Guix (see attached), with some
patches (also attached).

How is is that I overlooked this thread?  I spent last Thursday --
reluctantly -- adding webkitgtk bindings to guile-gnome and debugging
an initial browser test.  With Guile-GI it worked in minutes! :-)

One of the patches adds the web browser example and the last one adds an
editor example...but that segfaults in the key-press-event handler.

I've just noticed test/closures.c -- is that intended for handlers like
key-press-event; are they different from `clicked'?

Patches also on my `wip' branch: https://gitlab.com/janneke/guile-gi.git

LGTM!

Guile-GI has the potential to make a lot of people happy.  :-)

Thanks,

Yes, even if they're mostly developers atm ;-)  Pushed to master as

    bdf2dd797e1e57dab1d504a6e1af783ec5802afd

Teaser added to the Guile-GI README

--8<---------------cut here---------------start------------->8---
Try:

    guix environment --ad-hoc -l guix.scm guile
    guile-gi test/example-1.scm
    guile-gi test/browser.scm

Or, create and run in a development environment

    guix environment -l guix.scm
    ./bootstrap && ./configure && make
    tools/uninstalled-env tools/guile-gi test/browser.scm
    tools/uninstalled-env tools/guile-gi test/editor.scm

This is me trying to explain to myself how the meta_marshaller was working
in PyGObject, on which much of this code is based.

I am pleased and super embarrassed that someone has taken the time to
patch this code.  It is really rough code.  I had lost momentum on
this project, but, I'll try to get back to it.

Thanks for checking it out.

Ah, that makes sense.  I started playing with it and learned one or two
things, until i found src/gclosure.c :-)

Have you seen the gclosure implementation in guile-gnome, would that be
any help?

    https://git.savannah.gnu.org/cgit/guile-gnome.git/tree/glib/gnome/gobject/gclosure.scm

I'm quite new to all this, I cannot see the great difference in gtk+2
and gtk+3 here, even...

Great!

Thanks for this awesome project, it's real impressive :) I'll update the
guix package to your git (or a next release) again when that builds
without patches.

Both guile-gnome and my hack have two parts
- an introspection layer
- a gobject-to-guile binding

I had a chat with Wingo at the last FOSDEM, and he thinks the
gobject-to-guile binding could be reused, and that I could just swap
the gwrap GTK+2 introspection layer with a GObject introspection
layer.  I began analyzing that path a few months before life
intervened.

I incorporated these, and fixed the bug that caused your editor example
to fail.  Thanks!

Thanks,
Mike

Okay, good.

Oh great, and that's fast.  Thanks!  You maybe even did a bit too well,
the `bytes_new_null_size.scm' test now passes.  I added that to
XFAIL_TEST because it fails -- now make check fails because this test is
fixed.

The attach patch removes that workaround again.  If you apply this or
something equivalent, I will update the Guix package to point to your
updated repo.

Greetings,
jannneke
