Alternative to GLFW in pure Rust.

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

## [Documentation](http://tomaka.github.io/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;

fn main() {
    let window = glutin::Window::new().unwrap();

    unsafe { window.make_current() };

    unsafe {
        gl::load_with(|symbol| window.get_proc_address(symbol) as *const _);

        gl::ClearColor(0.0, 1.0, 0.0, 1.0);
    }

    for event in window.wait_events() {
        unsafe { gl::Clear(gl::COLOR_BUFFER_BIT) };
        window.swap_buffers();

        match event {
            glutin::Event::Closed => break,
            _ => ()
        }
    }
}
```

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.
