Re: [Boost-users] [fusion] how to get the tuple of min values of 2 tuples whatever their length?

Thank you all! It works now with the code below. What was the most difficult was to find the headers to include. Frédéric #include <iostream> #include <string> #include #include #include #include #include #include #include typedef boost::fusion::vector Key; template typename boost::fusion::result_of::transform< boost::fusion::zip_view<SeqOfSeqs> const, boost::fusion::fused_function_object >::type n_ary_transform(const SeqOfSeqs &s, const Func &f) { return boost::fusion::transform( boost::fusion::zip_view<SeqOfSeqs>(s), boost::fusion::fused_function_object(f)); } struct min { template <typename Sig> struct result; template struct result< Self(T, T) > { typedef typename boost::remove_reference<T>::type type; }; template<typename T> T operator()(const T &lhs, const T &rhs) const { return std::min(lhs, rhs); } }; struct print { template <class T> void operator()(const T &rhs) const { std::cout<
