I like the ideas you put forth here. Thanks. Though, I wonder if it could be taken a few steps further ... A boost formatting library
81 typedef boost::format::context_adapter< 82 struct timeval, 83 boost::format::context_spec< 84 boost::format::context_element<'d', ...> 85> > timeval_context_t; 86 87 boost::format::basic_formatter<timeval_context_t> fmt; 88 89 struct timeval tv; 90 gettimeofday(&tv, NULL); 91 92 // Standard usage 93 std::cout<< fmt("%d:%d",tv.tv_sec, tv.tv_usec)<< std::endl; 94 95 // Output the first, then the second context elements 96 std::cout<< fmt("%{1}:%{2}",tv)<< std::endl;
I like where the idea is taking me and I'm working on the implementation details now
IUC what you want to achieve is to format a UDT using its parts. I think that seen the UDT as a tuple could help. What about using the {i,j} to refer to the j-th part of the i-th parameter? In this way you could mix several parameter with the same format. std::cout<< fmt("{1,1}:{1,2} = {2}") % tv % i; I think I start to see how such a library could help to make easier the Stopwatch reporting. I would be greatfull if you could explain how this can be applied in my context. Thanks, Vicente
