> strings are ~4 instructions (test for null terminator, output character, branch back two). that's C strings. You also need to handle (size, data) strings like std::string_view For the record, here's what fmt allows (from the docs): fmt::print(fmt::emphasis::bold | fg(fmt::color::red) , "Elapsed time: {0:.2f} seconds", 1.23); fmt::print("Elapsed time: {0:.2f} seconds" , fmt::styled(1.23, fmt::fg(fmt::color::green) fmt::bg(fmt::color::blue))); fmt::print("{}", fmt::join(std::vector<int>{1, 2, 3}, ", ")); fmt::print("strftime-like format: {:%H:%M:%S}\n", 3h + 15min + 30s); you really think you can replicate that in 50 bytes?
