About all my projects
This repository is a language binding for Raku. The set of distributions is for Gtk version 3.
All the modules from Gnome::Gtk3 are depending on other Gnome packages like Gnome::Gio and Gnome::Glib. The implementations of the modules are tagged with :api<1>. This is done to prevent problems with the newer installment around Gnome::Gtk4. All you have to do is using the proper tag when installing the packages and in the use statements.
Using zef;
zef install Gnome::Gtk3:api<2>
Example to load the Window module;
use Gnome::Gtk3::Window::api<1>;
