Trip report: Fall ISO C++ standards meeting (San Diego) by Herb Sutter

From the article:

On Saturday November 10, the ISO C++ committee completed its fall meeting in San Diego, California, USA, hosted with thanks by Qualcomm. This was the biggest ISO C++ meeting in our 29-year history, with some 180 people at the meeting, representing 12 nations... Because this is one of the last meetings for adding features to C++20, we gave priority to proposals that might make C++20, and we adopted a number of them for C++20...

HPX V1.2 released—STE||AR Group
▻http://isocpp.org/feeder/?FeederAction=clicked&feed=All+Posts&seed=http%3A%2F%2Fisocpp.org%2Fblog%2F2

https://isocpp.org/files/img/stellar_logo.png

The STE||AR Group has released V1.2 of HPX — A C++ Standard library for parallelism and concurrency.

HPX V1.2 Released

The newest version of HPX (V1.2) is now available for download! Please see here for the release notes. This release is the first in our more frequent release schedule. We are aiming to produce one release every six months in an effort to get new features and stable releases out to users more quickly.

HPX exposes an API fully conforming to the parts of the C++11/C++14/C++17 standards that are related to parallelism and concurrency, extended and applied to distributed and heterogeneous computing, and aligned with the ongoing standardization discussions.

HPX is a general purpose parallel C++ runtime system for applications of any scale. It implements all (...)

Use the official range-v3 with MSVC 2017 version 15.9—CoderCasey
▻http://isocpp.org/feeder/?FeederAction=clicked&feed=All+Posts&seed=http%3A%2F%2Fisocpp.org%2Fblog%2F2

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.

How to Retrieve the Firsts from a Collection of Pairs

Simple.

How to Retrieve the Firsts from a Collection of Pairs by Jonathan Boccara

From the article:

When using the STL, there is a use case that pops up every now and then and that often causes more trouble than necessary: if we have a collection of pairs, like an std::vector of pairs, or simply a std::map, how can we retrieve the collection of the first elements of each item in the collection?

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.

CopperSpice: Sequencing
▻http://isocpp.org/feeder/?FeederAction=clicked&feed=All+Posts&seed=http%3A%2F%2Fisocpp.org%2Fblog%2F2

New video on the CopperSpice YouTube Channel:

Sequencing

by Barbara Geller and Ansel Sermersheim

About the video:

This video discusses sequencing and the ordering of expressions. We look at how the idea of sequence points was redesigned as the more general system of sequencing in C++11 and how new sequence rules were added in C++17 to further constrain expression evaluation. We also show how a detailed understanding of side effects and their interaction with sequencing is required to avoid undefined behavior.

Even more so, Sean Parent suggests that all coding guildines should be replaceed with “No raw loops” in order to improve code (...)

Pacific++ 2018: C++ Past vs. Future by Titus Winters

From the video:

Over the last 35 years, C++ has remained a constant fixture in the programming landscape. With advancements in the language through C++11, 14, and 17, we’ve created new dialects that have breathed new life into C++. With C++ Core Guidelines and a rich community of authors and speakers providing guidance on C++, it is easier now to steer clear of problem areas and hopefully stay in the “good parts” of the language. Or at least, that’s what we’d like. In practice, many habits of C++ programmers are unsafe and will be hard to keep working. The triple perils of ADL, ODR, and ABI leave a wide assortment of pitfalls for code maintenance. Many systems happen to work, but perhaps (...)

Modules Are Not Precompiled Headers—Guillaume Racicot

Interesting talk about modules.

Modules Are Not Precompiled Headers by Guillaume Racicot

From the article:

Modules have been the subject of many controversies in the C++ community in the recent past and there seem to be some misconception floating around recently about modules. Important decisions will soon be made, and I wanted to clear some of the facts and raise potentially good questions about modules and the path to their adoption. I do not want to argue about how modules should have been and what should have not been. Instead I want to talk tabout modules as they are today, in the merged (...)

Introducing Conduit for C++: Lazy Sequences Using the Coroutine TS—Buckaroo
▻http://isocpp.org/feeder/?FeederAction=clicked&feed=All+Posts&seed=http%3A%2F%2Fisocpp.org%2Fblog%2F2

It is worth looking at it.

Introducing Conduit for C++: Lazy Sequences Using the Coroutine TS by Buckaroo

From the article:

Conduit is a new library that leverages the Coroutine TS to introduce lazy sequences to C++. Lazy sequences are an idea that’s very popular in the functional-programming community, but less common in the C++ world. Simply put, a lazy sequence is one where the elements are computed as they are requested, rather than in advance. This can lead to big efficiency gains since you only perform the computation required. It also allows you to represent infinite sequences, which of course could never fit into a vector! Let’s see how Conduit works with some simple (...)

From the article:

This post is part of a three-part series about using the Clang AST Matchers to mechanically refactor C++ code. In the last post, we ensured that the code is at least buildable with Clang. While that part was only interesting to those whose code was not yet building with Clang, the rest of the series appeals to a general C++ audience. There are many other resources on the internet covering use of existing clang-tidy checks and their motivation, such as my previous employer. There is very little information online about the developer workflow and tools to use when creating custom extensions for source to source transformations with clang-tidy. This blog series (...)
