I'm also studying file iteration so I can see if that helps me out.
File iteration works good with typeof, and you don't have to explicitly specify IDs. The only problem -- you can't use the file iteration in a macro.
(OTOH, I am thinking of adopting the same strategy, so that people don't have re-entrancy problems when using typeof.)
Please do adopt this strategy. Currently this kind of code doesn't work:
BOOST_TYPEOF_REGISTER_TYPE( ^^^^^ boost::mpl::math::string_c_to_double , BOOST_MPL_PP_ARG_SEQ(unsigned char, 40) )
BOOST_MPL_PP_ARG_SEQ uses BOOST_PP_REPEAT to create a sequence of N elements containing the specified primitive integral type.
Do you mean BOOST_TYPEOF_REGISTER_TEMPLATE? I am not sure REPEAT is a problem here. The following example works (vc71): ---------------- #define BOOST_TYPEOF_COMPLIANT #include <boost/typeof/typeof.hpp> template<int n, short m> class x {}; #define seq (int)(short) #define MACRO(z, n, text) (BOOST_PP_SEQ_ELEM(n, text)) BOOST_TYPEOF_REGISTER_TEMPLATE(x, BOOST_PP_REPEAT(BOOST_PP_SEQ_SIZE(seq), MACRO, seq)) typedef BOOST_TYPEOF((x<1, 2>())) type; type y; int main() {} ----------------- Regards, Arkadiy
