Re: how to get all the attributes out of a parser

Hi Joel!

Got it! But where is a list of required includes for enabling boost::tuple?

I tried including these to no avail:

#include <boost/fusion/adapted/boost_tuple/boost_tuple_iterator.hpp>
#include <boost/fusion/adapted/boost_tuple.hpp>
#include <boost/fusion/adapted/std_tuple.hpp>
#include <boost/fusion/include/adapter.hpp>
#include <boost/fusion/functional/adapter.hpp>

Regards,
Juan Dent

Juan, you *can* use boost tuple of course. Just make sure it is properly adapted, by including the necessary fusion adapter includes.

P.S. I don't think the documentation is at fault. I think you missed this part:
https://bit.ly/3ohpIQN

where it's clearly stated:
"The notation tuple<A, B> is used as a placeholder expression for any fusion sequence holding the types A and B, such as boost::fusion::tuple<A, B> or std::pair<A, B> (for more information see Boost.Fusion)."
