Raylib 5.5 bindings for the Fennel programming language for the sake of interest.

Provides full coverage of:

• raylib.h main cheatsheet
• raymath.h math module

Includes:

• Built-in Raylib dynamic libraries for Windows and Linux (x64).
• Lume library
• 7 examples. Some of them are adaptations of official examples, the rest are custom ones.
• Makefile for both Windows and Linux

Example

Bindings use kebab-case naming

(local rl (require :lib.raylib))
(local lume (require :lib.lume))

(print "epic")
(-> 4.5
    (lume.round)
    (print))

(rl.init-window 640 640 "Fennel & Raylib")
(rl.set-target-fps 60)
(local background (rl.Color 161 212 242 250))

(while (not (rl.window-should-close))
  (rl.begin-drawing)
  (rl.clear-background background)
  (rl.end-drawing))

(rl.close-window)
(print "That's all")

Requirements

You need to have Luajit and Fennel installed. The main bindings file which you want to import is raylib.fnl.

• Luajit installation is very easy. Just follow the instructions Windows users read carefully the "Installing LuaJIT" section of the page: "Copy luajit.exe and lua51.dll (built in the src directory)..."
• Likewise with the Fennel (I install it via the script fennel-1.5.1 version)

fennel.bat script to run Fennel on Windows

@echo off
luajit C:\Games\Fennel\fennel1.5.1 %*

How to start using it

Just git clone this repo, cd fnl-raylib and then

fennel main.fnl

or

make run

or

fennel examples/core/core-input-keys.fnl

or (after make build)

luajit main.lua

or

luajit examples/core/core-input-mouse.lua

you got it.

How to build an executable

Prerequirements

• gcc compiler
• (if windows) LuaJIT installation into the C:\ path. (When you installed luajit, you should git clone their repo from the C:\ folder)

Both C compiler and LuaJIT installation path could be tweaked and replaced by yourself!

So how to build an executable?

Run

make release

or if you want to do it manually:

1. Compile Fennel to Lua

make build

2. Compile Lua to Bytecode

luajit -b main.lua main.luac

3. Create a C Wrapper and comile it

• Linux

gcc -o main main.c -lluajit-5.1

• Windows:

gcc -o main main.c -I"C:\LuaJIT\src" -L"C:\LuaJIT\src" -l"luajit-5.1"

4. Run your executable! Test how it works

./main

5. Package a release

Copy main, main.luac files and lib folder into seperate directory (for example in release)
