# GNUI
**GNUI** (pronounced `/ʒe.ɛn.y.i/`) is a high-performance, modern alternative to GTK, designed specifically for GNOME. It is built from the ground up in pure Rust to provide the "Adwaita" look and feel without the legacy baggage of C, GObject, or complex FFI bindings.
[Documentation](https://gnui.dev)
## Motivation
Developing GNOME apps with `gtk4-rs` often feels like **fighting the tool** rather than building the app. The numerous C dependencies bring exhausting issues when bound to Rust. **GNUI and its dependencies are full Rust**, and directly usable in your project using one simple import.
Thinking of a Rust-native framework for GNOME also brought the opportunity to make the library more "rusty": **easier and more intuitive**.
### Why not use Iced or Slint?
GTK is at the core of GNOME's UI experience. Iced and Slint both come with specific design choices that don't match GNOME's environment. GNUI comes **by default** with `libatawia`'s look, and displays native-looking GNOME components.
## Installation
```bash
# yeah, it's that simple
cargo add gnui
```
## Quick example
Use a declarative approach that feels natural in Rust.
```rust
fn view(state: &AppState) -> Element {
Column::new()
.padding(12)
.spacing(8)
.add(
HeaderBar::new()
.title("My App")
.show_close_button(true)
)
.add(
Button::with_label("Click Me")
.accent_style()
.on_click(Message::Increment)
.border(2.0)
)
}
```
