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 {{variable}} 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.
