raylib-lua

LuaJIT-based binding for raylib, a simple and easy-to-use library to learn videogames programming.

This binding is partially based on raylib-wren/wray.

Usage (raylua_s)

raylua_s is the script-mode binary of raylib-lua. Without any argument, you get into the REPL which gives you a minimal Lua shell that allows you to run Lua code from terminal.

You can specify a Lua file as argument to run the specified Lua file.

Usage (raylua_e)

raylua_e is the embedding-mode binary of raylib-lua.

This binary allows you to build standalone raylib applications from Lua code.

There are 3 ways to use it :

• zip mode : If you specify a zip file as argument, this zip will be used as payload application, this file expects to have a main.lua which is the entry point of the application.
• directory mode : Similar to zip mode except that it automatically build the zip payload from the specified directory.
• lua mode : Build the executable from a single Lua file.

Using require in embedded mode works as expected but dofile and loadfile may not work as expected as these functions load from a external file rather than from package loaders.

Building / Updating Raylib / Contribution

To build raylib-lua from source, you need to take care that submodules are imported, if not or you are unsure :

git submodule init
git submodule update

A Lua working interpreter is needed, by default luajit is used, to override it, edit LUA variable in makefile.

This make take some time depending on network bandwidth. Then, raylib-lua should build as expected using make tool with a working C compiler.

If you need to update raylib binding, there are few tasks to do :

• update tools/api.h functions signatures, keep file clean with exactly one function per line.
• update struct definitions in src/raylib.lua
