Chaining Comparisons: Seeking Information from the Audience--Barry Revzin

By Adrien Hamelin | Jan 10, 2018 02:26 PM | Tags: experimental community

A nice example of committee members reaching out to the community for data/input on proposed changes that could have a breaking impact.

Chaining Comparisons: Seeking Information from the Audience

by Barry Revzin

From the article:

At the last standards committee meeting in Albuquerque, the spaceship operator was adopted into the working draft for what will eventually be C++20. I’m already pretty excited about that. But one of the initial “optional” parts of Herb Sutter’s original spaceship proposal (which was dropped early) was to support chaining comparisons...

Report from using std::cpp 2017 -- Daniel Garcia

By jdgarcia | Jan 9, 2018 10:40 AM | Tags: community

Last November, 30th we had the 5th edition of using std::cpp (the annual C++ conference in Spain). Around 200 people gathered for a one-day event of C++ talks.

Using std::cpp 2017 Conference Report

by Daniel Garcia

From the report:

We used the evaluation forms to survey what people is using in their daily job. And we got some pleasent surprises about new standards adoption. It seems C++98/03 usage is going down!

Clang 5 in a Docker container for C++17 development--SolarianProgrammer

Very convenient to create a development environment without hassles.

Clang 5 in a Docker container for C++17 development

by SolarianProgrammer

From the article:

If you want to try the new C++17, using Clang in a Docker container, you are in the right place. Running Clang in a container has the advantage that it is light on resources and won’t mess with your underlying OS. The last point is especially important if your host operating system is macOS, on which it is a really bad idea to directly install a binary Clang other than the one that comes with Xcode. I’ve tested the approach presented in this article on Windows 10, macOS High Sierra and Ubuntu Linux.

C++17 Feature Removals And Deprecations--Stephan T. Lavavej

This is about visual studio, but this is also about how the deprecated mechanisms work.

C++17 Feature Removals And Deprecations

by Stephan T. Lavavej

From the article:

Technology advances by inventing new ways of doing things and by discarding old ways. The C++ Standardization Committee is simultaneously adding new features and removing old features at a gradual pace, because we’ve discovered thoroughly better ways of writing code. While feature removals can be annoying, in the sense that programmers need to go change old codebases in order to make them conform to new Standards, they’re also important. Feature removals simplify the Core Language and Standard Library, avoiding the doom of accreting complexity forever. Additionally, removing old features makes it easier to read and write code. C++ will always be a language that offers programmers many ways to write something, but by taking away inferior techniques, it’s easier to choose one of the remaining techniques which are more modern...
