☑ Read/Write/Add/Remove lua global variable at C++ side.
☑ Lua could send any variable to C++, and C++ could send then back.
☑ Support to create C extension module.

Lua 5.3 (tested up to 5.4)

Example

-- ClassIntoLua.lua

object = NewObject()

num = object:count(3,4)

print("3 + 4 = " .. num)

// main.cpp

#include "luapp.hpp"

class MyClass
{
public:

    MyClass()
    {
        printf("do MyClass::MyClass()\n");
    }

    ~MyClass()
    {
        printf("do MyClass::~MyClass()\n");
    }

    lua::Int count( lua::Int num01,
                    lua::Int num02)
    {
        return num01 + num02;
    }
};

int main()
{
    lua::State<>    lua;

    lua.bindMethod("count",&MyClass::count);

    lua.bindClassEx<MyClass>("NewObject");

    lua.run(".","ClassIntoLua.lua");

    return 0;
}
