lua_tostring remove value from stack. Isn't it ? So I should just push a key back late.
No! lua_toxxx don't remove (pop) the value from the stack!
My sample loop fills the stack with key value pairs because I thought you would like to. If you don't need this, you could write the loop much easier:Your code works, but unfortunately problem still exists. I can add my key to table before I iterated throuph it, but not after it. i.e lua_pushstring(L, "RRN"); lua_pushstring(L, "abcd"); lua_settable(L,-3); works fine before loop but doesn't work after it.
lua_pushnil(L);
while (lua_next(L, t))
{
lua_pushvalue(L, -2); /* make copy of key */
const char *key = lua_tostring(L, -1); /* note index! (copy) */
const char *val = lua_tostring(L, -2);
cerr << "Key: " << key << " Val:" << val << endl;
lua_pop(L, 2); /* pops value and copy of key */
}
