Re: pair()-like iterator in C++

[trepan <trepan@...>]

const int table = // a positive lua index
for (lua_pushnil(L); lua_next(L, table) != 0; lua_pop(L, 1)) {
 if (lua_isstring(L, -2)) { // key
   if (lua_isstring(L, -1)) { // value
     myMap[lua_tostring(L, -2)] = lua_tostring(L, -1);
   }
 }
}
