I'd like to gauge the interest in adding the following library to boost: https://github.com/rokudev/rostd/blob/main/include/rostd/printx.hpp It's a simple library that checks and rewrites the format string at compile time in order to fortify it for use with printf, leaving the object code with only a call to the underlying C-standard printf-family function. It's a single header and requires C++20 or above (for cNTTP support). It contains these four functions: printf, sprintf, snprintf, fprintf These functions are used like so: printf<"Hello %s\n">("World!"); char buf[20]; sprintf<"Hello %s\n">(buf, "World!"); // yes, it's safe char buf[20]; snprintf<"Hello %s\n">(buf, sizeof buf, "World!"); fprintf<"Hello %s\n">(file, "World!"); Features/rationale: * It provides old-style printf (supports all standard printf specifiers). * Fully type-safe. No format string attacks. Issues are found at compile time. * Length modifiers are deduced; these format strings are portable. (No PRIu64 inttypes stuff needed anymore, just use %u) * Adds %? format specifier (print whatever type is there). * Compiles to std::printf (much smaller object code than std::format). * Provides a way for developers to easily adapt this printf formatting capability to their own functions (logging, etc.) More detailed rationale is here: https://github.com/rokudev/rostd/blob/main/doc/printx.adoc
