Formatting a Drive with fmt

How to format a drive using {fmt}. #programmingtips #include <fmt/format.h> struct drive { std::string path; }; template <> struct fmt::formatter<drive> : fmt::formatter<int> { auto format(const drive& d, fmt::format_context& ctx) { auto command = fmt::format("sudo mkfs.ext4 {}", d.path); system(command.c_str()); return ctx.out(); } }; int main() { fmt::format("{}", drive("/dev/sda1")); }

A programming tips post shows C++ code that defines a custom {fmt} formatter for a drive. Formatting the drive secretly runs a sudo mkfs.ext4 command on /dev/sda1, which would erase and reformat the disk. The joke is a malicious or dangerously misleading code example disguised as a helpful formatting tutorial, suitable as a reaction to unsafe programming advice.
