[Boost-users] Boost Spirit X3 and spaces

Hi, What is the best strategy to handle spaces with X3? The files I want to parse have sometimes spaces or tabs for separators, but I also need to scan number that have an attached suffix (so x3::double_ >> *x3::char_). If now I want to parse groups of strings, starting with a rule like const auto pin = x3::rule<class pin, std::string>() = x3::alpha >> *x3::char_; what is the best to create a vector of these? *pin or pin % ' ' and will the latter also handle tabs by default?
