Trip Report: C++ Standards Meeting in Jacksonville, February 2016

by Botond Ballo

From the article:

Last week I attended a meeting of the ISO C++ Standards Committee in Jacksonville, Florida. This was the first committee meeting in 2016; you can find my reports on the 2015 meetings here (May 2015, Lenexa) and here (October 2015, Kona). These reports, particularly the Kona one, provide useful context for this post...

Concepts without Concepts--Andrzej Krzemieński

Concetps are good, but how can we get them?

Concepts without Concepts

by Andrzej Krzemieński

From the article:

“Concept” can mean two things in the context of C++ generic libraries:

  1. Something informal: something we know about template parameters, and can tell to other human programmers, e.g. in documentation.
  2. A language feature.

This post is about concepts in the first sense. It claims that we had concepts for quite a while already, and shows how we can use them to make generic libraries easier to use...

Guidelines Support Library Review: string_span--Marius Bancila

What is a string_span?

Guidelines Support Library Review: string_span<T>

by Marius Bancila

From the article:

In a previous post I have introduced the span<T> type from the Guidelines Support Library. This is a non-owning range of contiguous memory recommended to be used instead of pointers (and size counter) or standard containers (such as vector or array). span<T> can be used with strings, but the Guidelines Support Library provides a different span implementation for various types of strings. These string span types are available in the string_span.h header.

Trip report: C++ standards meeting in Jacksonville, Feb-Mar 2016 -- Herb Sutter

A comprehensive trip report from the just-concluded ISO C++ meeting:

Trip report: Winter ISO C++ standards meeting

by Herb Sutter

From the article:

On March 5, the ISO C++ committee completed its winter meeting in Jacksonville, FL, USA. We had record-tying attendance, with over 110 experts officially representing eight national bodies. As usual, we met for six days Monday through Saturday, and around the clock from 8:30am till 10pm most days, after which many people still went back to hang out in the lobby or their rooms to update papers. — The hotel had a baby grand piano outside the main meeting room lobby, and so late at night you could often walk by and find one of several committee members playing a tune, while as usual people collaborated on their proposals, perched on couches and tables clustered around glowing rectangles, incanting standardese to the soft strains of Russian folk ballads and arena rock.

Here’s a summary of what happened, with some details about the current ISO C++ process so you can see just how the work is progressing and getting released. I’ve tried to add some links to the relevant feature design papers, or to the papers that summarize what was done which in turn usually carry more links to the design papers...

Explanations on the span:

Guidelines Support Library Review: span<T>

by Marius Bancila

From the article:

The Guidelines Support Library is a Microsoft implementation of some of the types and functions described in the C++ Core Guidelines maintained by the Standard C++ Foundation. Among the types provided by the GSL is span<T> formerly known as array_view<T>. This article is an introduction to this type.

Returning multiple values from functions in C++--Eli Bendersky

A valid question to ask when writing functions:

Returning multiple values from functions in C++

by Eli Bendersky

From the article:

Since C++ has no built-in syntax for returning multiple values from functions and methods, programmers have been using a number of techniques to simulate this when needed, and the number has grown since the introduction of C++11. In this post I want to provide an overview of some of the options we have today for returning multiple values from functions, and possible future directions in the language...
