Hi Peter,

could you consider using "compile-time strings" such as Hana's? I don't have much use for a const char* in TMP algorithms.

The descriptor strings are "compile-time". This, for instance, works. ...

Here's how you can get a Hana string: #include <boost/describe.hpp> #include <boost/mp11.hpp> #include <boost/hana.hpp> #include <cstddef> using namespace boost::describe; using namespace boost::mp11; enum E { v1 }; BOOST_DESCRIBE_ENUM(E, v1) constexpr std::size_t strlen_( char const * s ) { std::size_t n = 0; while( *s++ ) ++n; return n; } template<class D, std::size_t... I> constexpr auto to_string_impl( index_sequence<I...> ) { return boost::hana::string_c<D::name[I]...>; } template<class D> constexpr auto to_string() { return to_string_impl<D>( make_index_sequence<strlen_(D::name)>() ); } using D = mp_first< describe_enumerators<E> >; constexpr auto st = to_string<D>(); #include <typeinfo> #include <cstdio> int main() { std::printf( "%s\n", typeid(st).name() ); }
