2021 C++ Standardization Highlights--Botond Ballo

2021 C++ Standardization Highlights

by Botond Ballo

From the article:

The ISO C++ Standards Committee (also known as WG21) has not met in person since its February 2020 meeting in Prague, which I wrote about here.

However, the committee and its subgroups have continued their work through remote collaboration, and a number of notable proposals have been adopted into C++23, the next language version, in this way, with many others in the pipeline.

In this post, I will outline some of the highlights of the committee’s work in 2021. (The post will also cover some material from the latter part of 2020, a period when remote collaboration was already underway but which I have not covered in any previous post.) I’ve been less involved in the committee than before, so this post will not be as comprehensive as my previous trip reports, but I hope to share the proposals I’ve found most notable...

C++ Reflection TS: A First Look -- Clément Pirelli

By Guy | Dec 8, 2021 10:49 AM | Tags: None

The Reflection TS was blessed with an example implementation recently, available on Compiler Explorer. Clément Pirelli gave it a spin and wrote a small post about what he found.

C++ Reflection TS: A First Look

by Clément Pirelli

From the article:

In this post, I’ll explain the basic ideas of the specification, how to write a simple generic “enum to string” function and go into a bit more detail with a proof-of-concept serialization function.
