Example

Invoke sin function from the Lua math library:

lmath = lua_require("math")
lsin = lua_get(lmath, "sin")

lua_call(lsin, 1)

The lua_require and lua_get function uses lua_call.

def lua_require(s)
{
    return lua_call("require", s)
}

def lua_get(table, index)
{
    return lua_call("rawget", table, index);
}

Beispiel

lmath = lua_require("math")
lsin = lua_get(lmath, "sin")

lua_call(lsin, 1)
    0.8415

Die lua_require und lua_get-Funktionen verwenden auch die lua_call-Funktion.

def lua_require(s)
{
    return lua_call("require", s)
}

def lua_get(table, index)
{
    return lua_call("rawget", table, index);
}
