Raclettui

Build terminal-themed wayland layer shell applications with Rust. Powered by Ratatui.

About

Raclettui allows you to create windows using wayland layer shell protocol and implements the Ratatui Backend trait to draw terminal style UIs. Layer shell protocol is usually used to create menus, bars and lockscreens. This project is still under active development. Expect bugs and breaking changes. However, it works if you would like to try it out. It has cpu and wgpu rendering backends. This library was developped to cook a UI for my project as no UI libraries in the rust ecosystem implementing the layer shell protocol were to my liking.

Quickstart

Setup

Add Raclettui as a dependency in your Cargo.toml:

cargo add raclettui

Here is a minimal example:


    use raclettui::{
        WindowBuilder,
        layer::{Anchor, Layer, KeyboardInteractivity},
        events::{WindowEvent, KeyCode},
    };
    use ratatui::{
        Terminal,
        border,
        style::{Style, Styled},
        widgets::{Block, Paragraph}
    };

    fn main(){

        let window = WindowBuilder::new()
            .set_namespace("example")
            .set_width(300)
            .set_height(300)
            .set_layer(Layer::Top)
            .set_anchor(Anchor::Top)
            .set_keyboard_interactivity(KeyboardInteractivity::OnDemand)
            .set_font_path("fonts/Some-Mono-Font.ttf")
            .set_font_size(18.)
            .bg_alpha(0.5)
            .init_wgpu();

        let events = window.get_event_queue();
        let mut terminal = Terminal::new(window).unwrap();

        'app_loop: loop{

            terminal.draw(|f| {
                let size = f.area();
                let paragraph = Paragraph::new("Hello World")
                    .block(
                        Block::new()
                        .borders(border!(TOP, BOTTOM, RIGHT, LEFT))
                    )
                    .set_style(Style::new().fg(ratatui::style::Color::Red).bg(ratatui::style::Color::Blue));
                f.render_widget(paragraph, size);
            }).unwrap();

            for ev in events.drain() {
                if let WindowEvent::Keyboard(key_event) = ev {
                    match key_event.code {
                        KeyCode::Char('q') => break 'app_loop,
                        _ => {}
                    }

                }
            }
        }
    }
