Lua-Sandbox Repository

This repository contains the Lua programming language, an embeddable scripting language with a focus on simplicity and extensibility. Lua is commonly used as a lightweight scripting language in various domains, including game development, embedded systems, and scripting within larger applications. This repo extend the lua language to be more friendly with different sandboxing use cases.

Library fusing System

In this repository, we have implemented a Library fusing System, which allows you to selectively load specific Lua libraries based on a fusion value. The luaL_openlibs function has been modified to support this feature. Here's the way it is implemented:

#include "lua.h"
#include "lauxlib.h"

LUALIB_API void luaL_openlibs(lua_State* L, int fuse) {
  // Base library
  if (fuse == 0 || fuse % 2 == 1) {
    luaL_requiref(L, LUA_GNAME, luaopen_base, 1);
    lua_pop(L, 1);
  }

  // Package library
  if (fuse % 3 == 0) {
    luaL_requiref(L, LUA_LOADLIBNAME, luaopen_package, 1);
    lua_pop(L, 1);
  }

  // ... (other libraries)

  // Debug library
  if (fuse % 29 == 0) {
    luaL_requiref(L, LUA_DBLIBNAME, luaopen_debug, 1);
    lua_pop(L, 1);
  }
}

In this system, the fuse value determines which libraries are loaded. Each library is associated with a prime number, and if the fuse value is divisible by that prime number, the corresponding library is loaded.

Fuse Number - Libraries Loaded Here is a table showing the valid fuse numbers and the corresponding libraries loaded:

Fuse Number Libraries Loaded
0 None
2 Base
3 Package
5 Coroutine
7 Table
11 IO
13 OS
17 String
19 Math
23 UTF8
29 Debug

Any combination of these would result in custom lib loading. for example :

fuse = 2*3 would load base and package lib

you can build lua as a library using the defualt makefile
