A native GPU-rendered Rust UI framework for macOS, Windows, Linux and the web, with its own renderer, text, layout and springs.

Every app can run headless, so an agent can render to PNG, dump the element tree and drive it with scripted input.

``` php
fn view(s: &State, _: &mut Cx<State>) -> El {
    let t = tok::theme(true);
    let label = text(if s.on { "Lights on" } else { "Lights off" })
        .font(type_::TITLE).color(t.text);
    let knob = el().key("knob").size(18.0, 18.0).radius(9.0).fill(t.knob)
        .absolute(if s.on { 18.0 } else { 2.0 }, 2.0);
    let switch = el().key("switch").role("switch").label("Lights").checked(s.on)
        .focusable(true).size(38.0, 22.0).radius(11.0)
        .fill(if s.on { tok::accent(0, true) } else { t.control_off })
        .motion(motion::SNAPPY)
        .on_press(|s: &mut State| s.on = !s.on)
        .child(knob);
    col().w_full().h_full().center().gap(16.0).fill(t.bg).child(label).child(switch)
}
```

Give your coding agent this repo. Have it start from [`examples/hello`](https://github.com/anomalyco/rune/blob/dev/examples/hello) and [` crates/rune/README.md`](https://github.com/anomalyco/rune/blob/dev/crates/rune/README.md), then check its own work headlessly by rendering PNGs and inspecting the element tree.

Build me a with Rune (github.com/anomalyco/rune). Start from examples/hello and check your work headlessly.

```
rune = { git = "https://github.com/anomalyco/rune", rev = "<dev rev>" }
```

Rune is pre-release. Pin a rev of `dev`; `dev` is never rewritten.

We don't take pull requests. Have your agent [open an issue](https://github.com/anomalyco/rune/issues)
describing the bug or idea, and our agents usually turn it around fast.
