• Syntax Highlighting: Syntax highlighting for editor and markdown components using Tree Sitter.

Showcase

Here is the first application: Longbridge Pro, built using GPUI Component.

We built multi-theme support in the application. This feature is not included in GPUI Component itself, but is based on the Theme feature, so it's easy to implement.

Usage

gpui = "0.2.2"
gpui-component = "0.4.0"

Basic Example

use gpui::*;
use gpui_component::{button::*, *};

pub struct HelloWorld;
impl Render for HelloWorld {
    fn render(&mut self, _: &mut Window, _: &mut Context<Self>) -> impl IntoElement {
        div()
            .v_flex()
            .gap_2()
            .size_full()
            .items_center()
            .justify_center()
            .child("Hello, World!")
            .child(
                Button::new("ok")
                    .primary()
                    .label("Let's Go!")
                    .on_click(|_, _, _| println!("Clicked!")),
            )
    }
}

fn main() {
    let app = Application::new();

    app.run(move |cx| {
        // This must be called before using any GPUI Component features.
        gpui_component::init(cx);

        cx.spawn(async move |cx| {
            cx.open_window(WindowOptions::default(), |window, cx| {
                let view = cx.new(|_| HelloWorld);
                // This first level on the window, should be a Root.
                cx.new(|cx| Root::new(view, window, cx))
            })?;

            Ok::<_, anyhow::Error>(())
        })
        .detach();
    });
}

WebView

Still early and experimental; there are a lot of limitations.

GPUI Component has a WebView element based on Wry. This is an optional feature, which you can enable with a feature flag.

gpui-component = { version = "0.4.0", features = ["webview"] }
wry = { version = "0.53.3, package = "lb-wry" }

More usage examples can be found in the story directory.

Icons

GPUI Component has an Icon element, but it does not include SVG files by default.

The example uses Lucide icons, but you can use any icons you like. Just name the SVG files as defined in IconName. You can add any icons you need to your project.

Development

We have a gallery of applications built with GPUI Component.

cargo run

More examples can be found in the examples directory. You can run them with cargo run --example <example_name>.
