C++ Core Guidelines: Non-Rules and Myths

by Rainer Grimm

Of course, you already know many non-rules and myths to C++. Non-rules and myths which we have to argument against when we use modern C++. The supporting section of the C++ core guidelines addresses the most resistant once but also provides alternatives...

Presenter Interviews: Stephan T. Lavavej

by Kevin Carpenter

In this week’s presenter interview, Kevin Carpenter welcomes Stephan T. Lavavej (STL) for a preview of his upcoming talk, Floating-Point charconv: Making Your Code 10x Faster With C++17’s Final Boss. Stephan discusses achieving a 3x to 10x speed up with charconv in C++17.

Combining Ranges and Smart Output Iterators

by Jonathan Boccara

In our current stage of development of smart output iterators, we have:

• some iterators, such as filter, transform, unzip or demux,
• the possibility to combine them: filter(pred) >>= transform(f) >>= unzip(back_inserter(output1), back_inserter(output2))
• their usage as the output iterator of an STL algorithm:

std::copy(begin(inputs), end(inputs), transform(f) >>= back_inserter(outputs));

What we’re going to work on today is removing the call to std::copy to have a pipeline made of output iterators only. And once we get such a pipeline, we will plug it to ranges, in order to benefit from the expressiveness of both ranges and smart output iterators, in the same expression...

Chaining Output Iterators Into a Pipeline

by Jonathan Boccara

We’ve been over a various set of smart output iterators over the past few weeks. Today we explore how to combine them and create expressive code.

C++ Core Guidelines: Supporting Sections

by Rainer Grimm

Let's recapitulate. In the last two years, I have written about 100 posts to the C++ Core Guidelines. Why? The document answers:  "This document is a set of guidelines for using C++ well. The aim of this document is to help people to use modern C++ effectively.". But my story does not end here. The guidelines have a supporting section...

Presenter Interviews: Kate Gregory

The German tour: Cologne trip report

by Guy Davidson

This trip report is a little different: not only did I attend the C++ Standard committee in Cologne, but I went on to speak at the Munich C++ meetup on the following Monday...

Trip Report: C++ Standards Meeting in Cologne, July 2019

by Botond Ballo

Last week I attended a meeting of the ISO C++ Standards Committee (also known as WG21) in Cologne, Germany. This was the second committee meeting in 2019; you can find my reports on preceding meetings here (February 2019, Kona) and here (November 2018, San Diego), and previous ones linked from those. These reports, particularly the Kona one, provide useful context for this post...
