Trip Report: C++ Standards Meeting in Belfast, November 2019

by Botond Ballo

From the article:

Last week I attended a meeting of the ISO C++ Standards Committee (also known as WG21) in Belfast, Northern Ireland. This was the third and last committee meeting in 2019; you can find my reports on preceding meetings here (July 2019, Cologne) and here (February 2019, Kona), and previous ones linked from those. These reports, particularly the Cologne one, provide useful context for this post...

Trip Report: Freestanding Errors in Belfast

by Ben Craig

From the article:

The C++ standards committee met in Belfast, Northern Ireland (UK) between Nov 4 and Nov 8. This was my fifth committee meeting, third evening session, and my first paper accepted into the standard. Through clever manipulation of the process, I was also able to fix 1.5% of all the national body comments SINGLE HANDEDLY (with the help of a coauthor, several reviewers, the entirety of LEWG and LWG, and a few national bodies)...

WG21 in my own backyard: Belfast trip report

by Guy Davidson

From the article:

November turned into a heavy travel month when I agreed to speak at both C++ Russia in St Petersburg and Meeting C++ in Berlin, either side of the Autumn WG21 committee in Belfast. I took what some considered to be “quite a risk” with St Petersburg: the date straddled the Brexit date, and I would be accompanied by my wife whom the organisers graciously agreed to pay to accompany me. She travels with an Irish passport, so the idea of both of us safely returning to the country immediately after a change to border law seemed potentially hazardous...

A Universal Async Abstraction for C++ -- Corentin Jabot

By Corentin Jabot | Nov 2, 2019 01:38 AM | Tags: None

Executors - of which P0443R11 is one of the latest iterations - is poised to be the most fundamental library addition to C++23.

A Universal Async Abstraction for C++

By Corentin Jabot

From the article:

What is it about?

It is first and foremost a quest to find the most basic building blocks on top of which one could build asynchronous, concurrent and parallel code, whether it be on a small chip or a supercomputer with thousands of CPUs and GPUs.

This is not an easy task and has kept many experts and many companies busy for many years.

fixing c++ with epochs -- Vittorio Romeo

By Vittorio Romeo | Sep 23, 2019 07:01 AM | Tags: None

This article covers a possible mechanism that would allow the C++ committee to make breaking changes to the language syntax while still fully preserving backwards compatibility. This would allow dangerous or obsolete constructs to be removed from C++, increasing safety and approachability of the language.

fixing c++ with epochs

by Vittorio Romeo

From the article:

Imagine that you have been designing a programming language for over 30 years and that it gradually became widely used across the globe. Some of the decisions you made at the beginning were excellent and contributed to the success of your project. Some others, however, were not the best: over the years you and your users realized that the world would have been a better place if those choices you made eons ago were slightly different. [...]

What if I told you that I could fix all of your problems? Even better, what if I told you that backward-compatibility will never be broken and that migration to newer versions of your language could be automated?

Trip Report: ISO C++ Meeting Cologne (2019) -- Matthias Gehre

Matthias Gehre’s trip report of the ISO C++ committee meeting in Cologne in 2019.

Trip Report: ISO C++ Meeting Cologne (2019)

by Matthias Gehre

From the trip report:

This is my trip report of the ISO C++ Meeting in Cologne – my first ISO C++ Meeting.

I will not so much focus on the big features that were approved for C++20 (there are better reports),

but more describe my personal experience. The report also contains discussions on

many lesser-known papers.
