Formatting user-defined types with {fmt} library

by Wojtek Gumuła

From the article:

C++ has two standardized ways of printing formatted text out already: printf-family functions inherited from C and I/O streams abstraction built on operator<<. Streams are considered more modern, providing type-safety and extensibility functionalities. However, printf have some notable advantages, too — at the cost of lost type-safety, user can use an interface that looks familiar to almost all developers, allowing for some ways of localization and more readable syntax. And then, there is {fmt} — yet another text formatting library, inspired by design already available in languages like Python and Rust...

Exploring C++20 - Class Types in Non-Type Template Parameters

by Tobias Widlund

From the article:

If I had to pick out my favourite features planned for C++20, then this one would definitely be amongst the top 5 since I love compile time programming. This feature makes it more natural to write templated code since it allows you to group data together and pass it to a template without having to resort to hacks.

To explain what this feature is about, I will start by talking about normal non-type template parameters from pre-C++20...
