# SDL-Elixir (status: WIP)

[SDL2](https://www.libsdl.org/) development library wrapper for Elixir empowered by

[NIFs](https://www.erlang.org/doc/man/erl_nif.html)

## Details

This library is the second iteration of my [sdl bindings](https://github.com/f1sty/sexdl) attempt.

## Run examples

To compile NIFs and launch example programs, run:

```bash

$ mix do deps.get, compile

$ iex -S mix

```

followed by:

```elixir

iex> Sdl.Examples.Image.run("/full/path/to/a/picture.png")

```

or:

```elixir

iex> Sdl.Examples.Simple.run()

```

Window with an image should appear in the first case. In the second one you should see regular

window with a pleasant bluish colour. If you ran second example, you also can close the window by

pressing `q`.
