Chunks-rs

A library that simplifies the process of making widgets for Wayland Compositors.

Chunks uses GTK4 and GTK4 Layer Shell at its core, and comes stock with a listener for the Hyprland IPC. This helps with changing Widget states when something changes, such as making the current window fullscreen.

Usage

Make sure you have GTK4 and GTK4-Layer-Shell installed on your system.

This will create a storage widget, similar to the one in the screenshot:

const STYLE: &str = "
window {
    background-color: transparent;
}

#storage {
    font-size: 34px;
    background-color: #000000;
    color: #FFFFFF;
}
";

fn main() {
    let factory = Factory::new("chunk.factory");

    let chunks = |factory: Application| {
        storage(&factory);

        load_css(STYLE);
    };

    factory.pollute(chunks);
}

fn storage(factory: &Application) {
    let tag = tag("storage");
    let margins = vec![(Edge::Top, 20), (Edge::Right, 160)];
    let anchors = EdgeConfig::TOP_RIGHT.to_vec();

    let storage_closure = || {
        let text = format!(
            "<span foreground='#FFFFFF'>{:.0}%</span>",
            Internal::get_storage(),
        );
        text
    };

    Internal::update_storage(&tag, storage_closure);

    Chunk::new(
        factory.clone(),
        "Storage".to_string(),
        tag,
        margins,
        anchors,
        Layer::Bottom,
    )
    .build();
}

Slabs & Plates

Chunks has recently had two new window type additions - Slabs & Plates. These are Popup Widgets, with similar implementations to Chunks.

Slabs & Plates have the exact same implementations, but have different behaviors.

Slabs will display whenever a change in the underlying text is detected. This is handy for standard Popups, like for volume detection.

Plates, on the other hand, display only once - whenever your Factory is initiated, and are destroyed after a set duration. These are more suited for greeter Popups.

These widget types do not need a designated layer, as they are set to Overlay by default. Instead of a layer, enter the amount of seconds you would like the Popups to display for.

Slab::new(
    factory.clone(),
    "Volume".to_string(),
    tag,
    margins,
    anchors,
    2,
)
.build();

Plate::new(
    factory.clone(),
    "Greeter".to_string(),
    tag,
    margins,
    anchors,
    2,
)
.build();
