C++20 and ReSharper C++

by Phil Nash

In July of this year, in the German city of Cologne, the ISO WG21 committee approved the full draft of C++20. After Belfast, in November, we now have just one more meeting (in Prague) to deal with national body comments and get their approval. That means that, barring any catastrophes, C++20 will become the current standard sometime after February of next year.

So C++20 is still in the future, but we now have a very good idea of everything that will be in it. Large sections of it have already been implemented in several compilers. But it’s not just the compilers that are getting ahead of the game. ReSharper C++ supports many of these features already, too – often with extra analysis and insights enabled by them.

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

by Botond Ballo

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...

5 Ways Using Braces Can Make Your C++ Code More Expressive

by Jonathan Boccara

A lot of languages use braces to structure code. But in C++, braces are much more than mortar for holding blocks of code together. In C++, braces have meaning.

Or more exactly, braces have several meanings. Here are 5 simple ways you can benefit from them to make your code more expressive...

Trip Report: Freestanding Errors in Belfast

by Ben Craig

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

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...

Support for C++20’s Concepts in CLion

by Anastasia Kazakova

Concepts are one of the biggest features coming in C++20, and knowing that, we’ve been thinking about supporting Concepts in CLion for quite a while. Enter Saar Raz with his C++20’s Concepts implementation in Clang! Long story short, we have been collaborating with Saar to merge his branch into our custom Clangd-based language engine in CLion, and started implementing some nice IDE features on top. Sounds ambitious enough, but we have thoroughly enjoyed the experience so far! A very early result of this collaboration was used by Saar in his CppCon 2019 talk on Concepts...

Bjarne Stroustrup: C++ | Artificial Intelligence (AI) Podcast

by Lex Fridman

Bjarne Stroustrup is the creator of C++, a programming language that after 40 years is still one of the most popular and powerful languages in the world. Its focus on fast, stable, robust code underlies many of the biggest systems in the world that we have come to rely on as a society. If you're watching this on YouTube, many of the critical back-end component of YouTube are written in C++. Same goes for Google, Facebook, Amazon, Twitter, most Microsoft applications, Adobe applications, most database systems, and most physical systems that operate in the real-world like cars, robots, rockets that launch us into space and one day will land us on Mars. This conversation is part of the Artificial Intelligence podcast.
