Rayex

Rayex provides Elixir NIF bindings to Raylib

WIP: many of the functions on raylib are yet not implemented, check the contributing section to help
NOTE: We are developing for the raylib 4.0-dev (that is why the CI is not passing right now, but you can use make test to test)

How to run

You need the following deps installed on your system:

• elixir
• raylib (master branch)
• pkg-config

Note: If you are using Nix or NixOS you can run nix-shell to get an ready to go env to work on!

Now you can run:

mix deps.get
iex -S mix

Testing Rayex

# open new window
Rayex.init_window 200, 200, 'window name'

# draw a line
Rayex.begin_drawing
Rayex.draw_line 10, 10, 50, 51, %{r: 255, g: 161, b: 0, a: 255}
Rayex.end_drawing

Also you can run our examples!!

Contributing

There are a few things that you need to know about the code:

• This project aims to run each one of those functions with elixir
• To do so, we are using Unifex to create NIFs
• On c_src/rayex/rayex.spec.exs you can find the definitions that will be generated by Unifex
• On c_src/rayex/rayex.c you can find how they are implemented
• On c_src/rayex/rayex.h and lib/unifex/code_generator/base_types/... you can find custom types
• On lib/rayex/unifex/raylib.ex is where the generated functions will be stored and used for each module under lib/rayex, the public API

Any contributions are appreciated
