Creating plugin

To create plugin you need to extend Tuner.Addin and in init block add your pages and content addins. Then build it to shared library.

Example:

namespace Test {
    public class Addin : Tuner.Addin {

        construct {
            add_from_resource("/org/example/TestAddin/test.ui");
        }
    }
}

This will add pages and content addins from /org/example/TestAddin/test.ui to Tuner.

test.ui

using Gtk 4.0;
using Tuner 1;

// Set translation domain
// Required if you need custom translation
// in your plugin
translation-domain "your-translations";

// Add new page to sidebar
Tuner.PanelPage {
    title: _("Test Page");
    tag: "testtag"; // Required if you want make your page extensible
    icon-name: "help-info-symbolic";

    // Creates new Adw.PreferenceGroup that that can be extended
    // by other plugins if id specified
    // Also allows to use widgets from libtuner
    Tuner.Group your_group_tag {
        title: _("Group Title");

        // Adw.SwitchRow with binding support
        // Can only be added to Tuner.Group
        Tuner.Switch {
            title: _("Over Amplification");

            // Binds this switch to GSettings
            binding: Tuner.Setting {
                schema-id: "org.gnome.desktop.sound";
                schema-key: "allow-volume-above-100-percent";
            };
        }
    }
}

Resulting library can be placed to ~/.local/share/tuner/plugins folder with plugin description file called <you plugin name>.plugin

test.plugin

[Plugin]
Name=Your name
Module=test

Where test should be replaced with your library name without lib prefix and .so. In example above test will be exanded to libtest.so
