Negative indexes are okay for the simple case, but when working with two
or three tables, they are a pain. I'll just use my own macro:
#define lua_nice_newtable(L) (lua_newtable(L), lua_gettop(L))
for example:
int lua_odbclibopen(lua_State *L)
{
int metatable, methods;
{metatable = lua_nice_newtable(L);
set_method(L, "gc", dbc_gcmethod);
{methods = lua_nice_newtable(L);
set_closure(L, "Execute", sql_execute, metatable);
set_closure(L, "TableList", sql_table_list, metatable);
set_closure(L, "Close", dbc_close, metatable);
{lua_pushvalue(L, LUA_GLOBALSINDEX);
set_closure(L, "DBConnect", dbc_connect, metatable);
{lua_pushstring(L, "gettable");
lua_pushvalue(L, methods);
lua_settable(L, metatable);}
lua_pop(L, 3);}}}
}
