Sexdl

SDL2 bindings for Elixir (NIFs)

TODO

• refresh on NIFs
• research on SDL library
• MVP with window showed
• unify error handling in NIFs
• add helper functions into Sexdl.Video for SDL_WindowFlags enum values
• make NIFs compilation process easier
• fix sdl_convert_surface_nif to accept same params as API function
• look into enif_alloc_resource more and decide how to handle pointers
• separate SDL2/SDL_video.h functions into Sexdl.Video module (maybe?)
• return map from new function in sdl_event.c
• fix elixir actions

Run MVP

To compile NIFs and launch sanity test program, run:

$ mix do deps.get, compile
$ iex -S mix

followed by:

iex> Sexdl.Mvp.run(~c"title")

Black window should appear for about 3 seconds.

You also can run:

iex> Sexdl.Mvp.run(~c"title", ~c"priv/test.png")

And you should see an owl on black background for the same time span:).
