Show HN: I Rewrote printf – Now 10x More Powerful (v1.3) After months of development, I'm excited to release uprintf v1.3 - the ultimate platform-independent printf replacement that works everywhere from bare-metal microcontrollers to modern OSes. What's new in v1.3: -Template System -Now with substitution like modern template engines -Multi-Output Streaming -Broadcast to multiple destinations simultaneously (UART, files, network) -String Builder - Dynamic string building with efficient memory management -Text Transformation -Built-in uppercase, lowercase, capitalize, reverse, and ROT13 transforms -Advanced Formatting - Text alignment, wrapping, and pattern-based formatting -Event System - Hook into output streams for monitoring and processing -Stream Processors -Real-time character transformation pipelines -State Machine - Lightweight state management for complex workflows And it's still: -Zero dependencies -Header-only -Fully portable -MIT licensed Perfect for embedded systems, CLI tools, and anywhere you need powerful formatting without bloat.
