Hello Users, I like to join two translation into a single one using the word 'and' if the code path require it, e.g. translation 1 is: "{1} error" and translation 2 is: "{1} warning" if the relevant err/warn counter are both != 0 I want to combine this statement using the mentioned 'and'. I guess, an example teels more than this here: see https://wandbox.org/permlink/HbnCLQKhHAb3eqZr or even on bottom. Line 89 ... 94 looks too complicated to me even for the translator which need an own context of the intend. I've seen a lot of dating formating flags, but nothings useful for my use case. BTW; does boost.locate still using auto_ptr? I had to add the option '-Wno-deprecated' to rid the warnings... Thanks, Olaf -----------------------8<-------------------------- #include <iostream> #include <boost/locale.hpp> struct context { std::size_t error_count; std::size_t warning_count; context() : error_count{ 0 } , warning_count{ 0 } { } }; struct failure_status { context const& ctx; failure_status(context const& ctx_) : ctx{ ctx_ } { } std::ostream& operator()(std::ostream& os) const; }; static inline std::ostream& operator<<(std::ostream& os, failure_status const& status) { return status(os); } namespace detail { struct error_message { std::size_t const count; explicit error_message(std::size_t count_) : count{ count_ } { } std::ostream& operator()(std::ostream& os) const { using boost::locale::format; using boost::locale::translate; if(count) { os << format(translate( "{1} error", "{1} errors", count)) % count ; } return os; } }; std::ostream& operator<<(std::ostream& os, error_message const& err_msg) { return err_msg(os); } struct warning_message { std::size_t const count; explicit warning_message(std::size_t count_) : count{ count_ } { } std::ostream& operator()(std::ostream& os) const { using boost::locale::format; using boost::locale::translate; if(count) { os << format(translate( "{1} warning", "{1} warnings", count)) % count ; } return os; } }; std::ostream& operator<<(std::ostream& os, warning_message const& warn_msg) { return warn_msg(os); } } // namespace detail std::ostream& failure_status::operator()(std::ostream& os) const { using detail::warning_message; using detail::error_message; using boost::locale::translate; bool const any_failure = [&] { return ctx.error_count || ctx.warning_count; }(); if(any_failure) { os << error_message(ctx.error_count); if(ctx.warning_count) { os << translate(" and "); // poor translator ... } os << warning_message(ctx.warning_count); os << translate(" generated."); } return os; } int main() { context ctx; ctx.error_count = 1; ctx.warning_count = 42; std::cout << failure_status(ctx) << "\n"; } ----------------------->8--------------------------
