LuaStick

LuaStick is a C++ program which enables exporting C++ function to Lua and calling Lua program from C++. You can export C++ classes, structs, namespaces, enums, constants and functions. To export them, you just add 3 slashes comment /// <stick export="true" /> into the C++ header.
For example, you can export the class 'X' and member function 'Func' like the following:

// main.h

/// <stick export="true" />
class X
{
    /// <stick export="true" />
    /// <param name="x" io="in" />
    void Func(int x)
    {
        std::cout << x * 2;
    }
};

To generate binding sources, run LuaStick.exe like the follwing command line:

>LuaStick.exe -out Stick Sticklib.h main.h

LuaStick.exe generates C++ source, header and HTML files.

The following is a simple program to make the class 'X' instance and call its method 'Func'.

// main.cpp

#include "Stick.h"

int main()
{
    Stickrun stickrun(luastick_init);
    std::string lua_src =
      "obj=X.New();"
      "obj:Func(10);";
    stickrun.DoString(nullptr, lua_src, "myscript");
}

If you write <summary> and other tag text contents, LuaStick.exe generates an API manual HTML file.

// main.h

/// <stick export="true" />
/// <summary>
/// This is class X.
/// </summary>
class X
{
    /// <stick export="true" />
    /// <summary>
    /// This is function Func.
    /// </summary>
    /// <param name="x" io="in">Parameter X</param>
    /// <returns>It returns double x</returns>
    int Func(int x)
    {
        return x * 2;
    }
};
