An improved version of ``std::tie``
|
||
|
|
-----------------------------------
|
||
|
|
|
||
|
|
`std::tie()`_ does not work well with :doc:`sol::function<function>`'s ``sol::function_result`` returns. Use ``sol::tie`` instead. Because they're both named `tie`, you'll need to be explicit when you use Sol's by naming it with the namespace (``sol::tie``), even with a ``using namespace sol;``. Here's an example:
|
||
|
|
|
||
|
|
.. code-block:: cpp
|
||
|
|
|
||
|
|
sol::state lua;
|
||
|
|
lua.open_libraries(sol::lib::base);
|
||
|
|
|
||
|
|
const auto& code = R"(
|
||
|
|
function test()
|
||
|
|
return 1, 2, 3
|
||
|
|
end
|
||
|
|
)";
|
||
|
|
lua.script(code);
|
||
|
|
|
||
|
|
int a, b, c;
|
||
|
|
//std::tie(a, b, c) = lua["test"]();
|
||
|
|
// will error: use the line below
|
||
|
|
sol::tie(a, b, c) = lua["test"]();
|
||
|
