Re: [Boost-users] [boost-users] How to put together a tuple type?

Hi Joel,

Oops, that should be

typedef mpl::vector_c consts_type; typedef fusion::vector vars_type;

vars_type vars; fusion::joint_view 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 #include #include #include #include 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 consts_type; typedef fusion::vector vars_type; vars_type vars; fusion::joint_view 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
