Trip Report: C++ Standards Meeting in San Diego, November 2018

by Botond Ballo

From the article:

A few weeks ago I attended a meeting of the ISO C++ Standards Committee (also known as WG21) in San Diego, California. This was the third committee meeting in 2018; you can find my reports on preceding meetings here (June 2018, Rapperswil) and here (March 2018, Jacksonville), and earlier ones linked from those. These reports, particularly the Rapperswil one, provide useful context for this post...

Exploring C++20 - Designated initialisers—Tobias Widlund

Will be very useful.

Exploring C++20 - Designated initialisers

by Tobias Widlund

From the article:

Compared to many other C++20 additions this one is quite small, only needing a single box of explanation on cppreference. Despite this, I quite like the feature as it helps code that uses aggregate initialisation to be more readable and less error prone - both are well needed in that area!

Better template support and error detection in C++ Modules with MSVC 2017 version 15.9—Cameron DaCa

It continues to improve.

Better template support and error detection in C++ Modules with MSVC 2017 version 15.9

by Cameron DaCamara

From the article:

It has been a long time since we last talked about C++ Modules. We feel it is time to revisit what has been happening under the hood of MSVC for modules.

The Visual C++ Team has been dedicated to pushing conformance to the standard with a focus on making the overall compiler implementation more robust and correct with the rejuvenation effort. This rejuvenation effort has given us the ability to substantially improve our modules implementation. We’ve mostly done this work transparently over the past few months until now. We are proud to say the work has reached a point where talking about it would hopefully provide developers with even more reasons to use C++ Modules with MSVC!

Trip report.

San Diego Committee Meeting: A Trip Report

by Corentin Jabot

From the article:

As I left Rapperswil earlier this year, I said very firmly that I would not go to the San Diego Meeting.

Crossing an ocean to work on C++ 12 hours a day for a week is indeed madness.

And so naturally, I found myself in a San Diego hotel straight from the 60s, to do some C++ for a week. With the exception of the author of this blog, all people there are incredibly smart and energetic, and so a lot of great work was done...

Trip Report: Freestanding in San Diego—Ben Craig

One more report.

Trip Report: Freestanding in San Diego

by Ben Craig

From the article:

All three are dealing with "freestanding". I've been working for the last year or so trying to redefine freestanding in a way that would be useful to more people. I have personal experience using C++ in various operating system kernels / drivers, and a bit of experience working on micro controllers and digital signal processors, so that's where my papers focused. At the CppCon 2018 SG14 meeting, some GPU companies have said that my definitions are useful for their architectures (with some tweaks), and I've heard from several other people that my definitions are even useful in some environments where performance and determinism are key, even when there is an OS. I'm still trying to figure out if and how to incorporate all these groups into one thing that could get standardized.

I pitched "Freestanding Proposal" at my first WG21 meeting was November of 2017 in Albuquerque. I was an unknown then. San Diego was my third WG21 meeting. All the papers and interviews and trip reports have now made it where people were asking me about freestanding quite frequently. There were a few times I got stopped while walking around by someone I had never talked to before, and they knew who I was, and asked about freestanding. I found this very flattering. I'm thrilled (and terrified) that my work is getting such visibility...

2018 San Diego ISO C++ Committee Trip Report

The report is here!

2018 San Diego ISO C++ Committee Trip Report

From the article:

The ISO C++ Committee met in San Diego, California ���� last week to continue work on the next International Standard (IS), C++20. This meeting was the last meeting to consider new proposals for C++20, but existing proposals like modules (on track) and coroutines (questions remain) that are in flight but not merged can still make C++20. We’ll make our final decisions about major language features at the next meeting.

Use the official range-v3 with MSVC 2017 version 15.9—CoderCasey

Everything is in the title.

Use the official range-v3 with MSVC 2017 version 15.9

by CoderCasey

From the article:

We’re happy to announce that the ongoing conformance work in the MSVC compiler has reached a new milestone: support for Eric Niebler’s range-v3 library. It’s no longer necessary to use the range-v3-vs2015 fork that was introduced for MSVC 2015 Update 3 support; true upstream range-v3 is now usable directly with MSVC 2017.
