Show HN: Uprintf a universal stb-style printf implementation for C (no OS) I've been frustrated by the lack of a truly portable, no-dependency printf for embedded and kernel development. Most solutions are either too bloated or missing key features. So I built Uprintf. It's a single-header library that gives you full printf (flags, width, precision, floats, even custom specifiers) from bare metal to desktop, with zero dependencies or #ifdef hell. Key features: · One header file, no dependencies, no dynamic allocation · Full standard support: %d, %x, %f, %.*s, etc. · Extensible with custom format handlers (add %T for your project) · Configurable: disable floats, set locale, etc. · MIT Licensed.
