Hello Guilers,

The ninth release candidate of the upcoming GNU G-Golf 0.8.0 release is
now available for testing:


* Tarball and a GPG detached signature [*]:

	http://ftp.gnu.org/gnu/g-golf/g-golf-0.8.0-rc9.tar.gz
	http://ftp.gnu.org/gnu/g-golf/g-golf-0.8.0-rc9.tar.gz.sig


* Install

Dependencies and complete installation instructions are given in the
distributed INSTALL file, or here:

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


* Noteworthy changes in 0.8.0-rc9

Here is a summary of the noteworthy changes in this release, also
available in NEWS file and on the G-Golf website.

** Examples

*** Adwaita Demo

The following Adwaita Demo pages have been added:

  AdwDemoPageAnimations

Note that this required quite a few changes compared to the upstream
demo, because in C, they can call gtk_widget_set_layout_manager, which
is not possible for (any) language bindings. Instead, language bindings
users must define a derived GtkLayoutManager class, and declare it as
the layout manager of the (derived GObject) class you are working
on. You may look at this (example) or the gtk-4 layout-manager and
layout-manager-2 examples to get inspired to write your first layout
manager derived class.

** Bug fixing

*** gi-argument->scm

Working on the AdwDemoPageAnimations port to G-Golf revealed an
important (now fixed) bug in the gi-argument->scm procedure.


* You can help

1. Testing by installing from the tarball, or from the source if you
   prefer, on the distro of your choice.

2. By running the distributed examples.

Ultimately, one of the best way to test, and participate, is to select
G-Golf to develop the next application of your dream! Here is an
overview of the GNOME platform libraries [1], accessible using G-Golf.
In particular, libadwaita [2] provides a number of widgets that change
their layout based on the available space. This can be used to make
applications adapt their UI between desktop and mobile devices (as shown
in the G-Golf port of the "Adwaita demo").


* Contact

Consider joining us on irc [3], where you may ask for help or report a
problem [4].

However, if you prefer:

	G-Golf uses the guile-user@gnu.org mailing list
	Report bugs to bug-g-golf@gnu.org


Thanks!
David


[*] Use a .sig file to verify that the corresponding file (without the
    .sig suffix) is intact.  First, be sure to download both the .sig
    file and the corresponding tarball.  Then, run a command like this:

	gpg --verify g-golf-0.8.0-rc9.tar.gz

    If that command fails because you don't have the required public
    key, then run this command to import it:

	gpg --keyserver keys.gnupg.net --recv-keys A3057AD7

    and rerun the 'gpg --verify' command

[4] When reporting a problem, or if you think you found a bug, it is
very important that you prepare a minimal reproducible example (MRE),
sometimes also referred to as a short self-contained correct example
(SSCCE)

Also, on irc, we chat :), so please do not write code snipsets directly
in the channel, unless 2 or 3 lines of code, nor (long/huge) error
messages of course - for more then 2 or 3 lines of code, or error
messages, always use a tor-friendly paste service (avoid those that
track its visitors and require javascript, thanks!).
