```toml
[dependencies]
glutin = "*"
```

## [Documentation](https://docs.rs/glutin)

## Try it!

```bash
git clone https://github.com/tomaka/glutin
cd glutin
cargo run --example window
```

## Usage

Glutin is an OpenGL context creation library and doesn't directly provide OpenGL bindings for you.

```toml
[dependencies]
gl = "*"
libc = "*"
```

```rust
extern crate gl;
extern crate glutin;
extern crate libc;

use glutin::GlContext;

fn main() {
    let events_loop = glutin::EventsLoop::new();
    let window = glutin::WindowBuilder::new()
        .with_title("Hello, world!")
        .with_dimensions(1024, 768);
    let context = glutin::ContextBuilder::new()
        .with_vsync(true);
    let gl_window = glutin::GlWindow::new(window, context, &events_loop).unwrap();

    unsafe {
        gl_window.make_current().unwrap();
    }

    unsafe {
        gl::load_with(|symbol| gl_window.get_proc_address(symbol) as *const _);
        gl::ClearColor(0.0, 1.0, 0.0, 1.0);
    }

    let mut running = true;
    while running {
        events_loop.poll_events(|event| {
            match event {
                glutin::winit::Event::WindowEvent{ event, .. } => match event {
                    glutin::winit::WindowEvent::Closed => running = false,
                    glutin::winit::WindowEvent::Resized(w, h) => gl_window.resize(w, h),
                },
                _ => ()
            }
        });

        unsafe {
            gl::Clear(gl::COLOR_BUFFER_BIT);
        }

        gl_window.swap_buffers().unwrap();
    }
}
```

Note that glutin aims at being a low-level brick in your rendering infrastructure. You are encouraged to write another layer of abstraction between glutin and your application.

## Platform-specific notes

### Android

 - To compile the examples for android, initialize the submodules, go to `deps/apk-builder/apk-builder` and run `cargo build`, then go back to `glutin` and call `ANDROID_HOME=/path/to/sdk NDK_HOME=/path/to/ndk NDK_STANDALONE=/path/to/standalone cargo test --no-run --target=arm-linux-androideabi`

### X11

 - The plan is that glutin tries to dynamically link-to and use wayland if possible. If it doesn't work, it will try xlib instead. If it doesn't work, it will try libcaca. This is work-in-progress.
