Understanding C++ Modules: Part 1: Hello Modules, and Module Units—Colby Pike

Complex, but useful!

Understanding C++ Modules: Part 1: Hello Modules, and Module Units

by Colby Pike

From the article:

My previous posts on modules have received a lot of attention. I’m happy that I’ve been able to kick-start a lot of conversation, but I’ve also seen that a large part of the community is still unclear on what modules actually are.

There is a lot of ground to cover. I can’t do it all in one sitting, and I doubt you’d want to read the entire thing in one go. I’ll be breaking this up, starting at the most high-level aspects and drilling down over time. I intend these posts will clarify and discuss what modules are, what they can do, and what they are intended to do, what they cannot do, and how they are used...

Lambdas: From C++11 to C++20, Part 2—Bartlomiej Filipek

The series continues!

Lambdas: From C++11 to C++20, Part 2

by Bartlomiej Filipek

From the article:

In the first part of the series we looked at lambdas from the perspective of C++03, C++11 and C++14. In that article, I described the motivation behind this powerful C++ feature, basic usage, syntax and improvements in each of the language standards. I also mentioned several corner cases.

Now it’s time to move into C++17 and look a bit into the future (very near future!): C++20...

Formatting user-defined types with {fmt} library—Wojtek Gumuła

The future.

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...
