Rune

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.

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)
}

Use it with your agent

Give your coding agent this repo. Have it start from examples/hello and 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.

Add it

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

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

On Windows, the MSVC toolchain (x86_64-pc-windows-msvc, rustup's default) needs only the Visual Studio C++ build tools rustup asks for. The GNU toolchain (x86_64-pc-windows-gnu) also needs MinGW-w64's binutils on PATH: windows-link (under parking_lot, libloading, windows-core and windows-sys, so under every Windows UI crate) imports with raw-dylib, rustc makes those import libraries with dlltool on GNU targets, and the dlltool in rustup's rust-mingw can't run without an as it doesn't ship (rust-lang/rust#140704). Without binutils the build stops at windows-result with error calling dlltool 'dlltool.exe': program not found. Install MSYS2, run pacman -S mingw-w64-ucrt-x86_64-binutils, and put C:\msys64\ucrt64\bin on PATH (or build with RUSTFLAGS=-Cdlltool=C:\msys64\ucrt64\bin\dlltool.exe).
