C++ {fmt} Library Overview & Cheat Sheets

{fmt} is a fast(er) and safe(r) alternative to C stdio (printf,...) and C++ iostreams (std::cout,...) that uses a Pythonesque format string syntax and is the origin and inspiration of C++20's std::format and C++23's upcoming std::print.

This article on hackingcpp.com offers a comprehensive and accessible overview of {fmt} with lots of runnable examples and visual aids:

• how to set it up
• quick overview of its interface and capabilities
• hierarchical, task-oriented "how-to print/format X" sections
• how to print custom types
• cheat sheets as quick reference for format specifications
