Hi Joel,
Oops, that should be
typedef mpl::vector_c<int, 4> consts_type; typedef fusion::vector<int, float, int, double> vars_type;
vars_type vars; fusion::joint_view<consts_type, vars_type> s3(consts_type(), vars);
Anyway, I'm sure you got the point. With our 's3' above, we can, for exemple, write (using boost::lambda):
fusion::for_each(s3, cout << _1 << endl);
to print all the items.
I just tried your suggestion and it works until the fusion::for_each() call. There, I get a million compiler errors. I'm sure I'm must missing something simple here. This is what I'm doing: #include <iostream> #include <tchar.h> #include <boost/lambda/lambda.hpp> #include <boost/mpl/vector_c.hpp> #include <boost/fusion/algorithm.hpp> #include <boost/fusion/sequence.hpp> using namespace std; using namespace boost; using namespace boost::lambda; struct s1 { static const int num_values = 1; int i; }; struct s2 { static const int num_values = 2; int i; int j; }; struct s3 { static const int num_values = 3; int i; int j; int k; }; struct s4 { static const int num_values = 4; int i; float j; int k; double l; }; template <class S> void doSomething( S& s ) { typedef mpl::vector_c<int, 4> consts_type; typedef fusion::vector<int, float, int, double> vars_type; vars_type vars; fusion::joint_view<consts_type, vars_type> view(consts_type(), vars); fusion::for_each( view, cout << _1 << endl ); } int _tmain(int argc, _TCHAR* argv[]) { s4 s; doSomething( s ); return 0; } When I got the CVS head there was no fusion documentation included. Is that correct? Greets, Christian
