Non-Ownership and Generic Programming and Regular types, oh my!

by Barry Revzin

From the article:

This post is about a specific collection of types in the C++ core language and standard library. I am not sure of a good way to name this collection, and some terms that come to mind come with their own baggage, so I’m going to for now group them together under an umbrella that is clearly widely unrelated to programming and call them Westie types (because, like my dog, they are awesome yet enigmatic).

IO2D demo: CPULoad -- Michael Kazakov

A walkthrough of the CPULoad demo from the 2D Graphics proposal:

IO2D demo: CPULoad

by Michael Kazakov

From the article:

In my humble opinion, the 2D graphics proposal might bring C++ a solid foundation for visualization support. It’s powerful enough to build complex structures on top of it – here I can refer to the sample SVG renderer as an example. At the same time, it’s not built around some particular low-level graphics API (i.e OpenGL/DirectX/Mantle/Metal/Vulkan), which come and go over time (who remembers Glide?). What is also very important about the proposal is its implementability – I wrote the CoreGraphics backend in ~3 months on a part-time basis. It can be assumed that writing a theoretical Direct2D backend might take about the same time. While it’s easy to propose “just” a support for PostScript, SVG or even HMTL5, the practical implementability of such extensive standards is very doubtful. Having said that, I do think that the proposal, while being a valid direction, is far from being perfect and needs a lot of polishing.

March 2018 ISO C++ Meeting Trip Report (SG1: Concurrency and Parallelism)

by Thomas Rodgers

From the article:

This year’s Winter ISO C++ Standard Committee meeting was held in March in Jacksonville, Florida. A number of larger features, for which there is substantial interest but which are also difficult to get right, were discussed:

• Concepts, along with Concept types from the Ranges TS; see P0898 and n4685
• Modules; see n4689
• Coroutines; see n4723
• Networking; see n4711
• Executors; see p0443

Trip report: Winter ISO C++ standards meeting (Jacksonville)

by Herb Sutter

From the article:

On Saturday March 17, the ISO C++ committee completed its winter meeting in Jacksonville, Florida, USA, hosted with thanks by the Standard C++ Foundation and Perennial. We had some 140 people at the meeting, representing 8 national bodies. As usual, we met for six days Monday through Saturday, including all evenings...

ISO C++ Committee – Jacksonville 2018, trip report -- Timur Doumler

By Anastasia Kazakova | Mar 29, 2018 06:53 AM | Tags: c++20

Timur Doumler has joined the CLion team in fall 2017. He continues to be active on the C++ Committee, as it fits well into JetBrains' strategy: our C++ team would like to be actively involved in the committee and feed our experience with implementing language features in our C++ tools back into the ongoing work on the evolution of the C++ language.

ISO C++ Committee – Jacksonville 2018 trip report

by Timur Doumler

From the article:

From the 12th to the 17th of March 2018, I travelled to Jacksonville, Florida, to attend the ISO C++ Committee meeting as JetBrains’ representative on the committee. I decided to focus on Evolution Working Group and cover the most relevant discussions concerning language evolution:

• Day 1: Structured bindings and concepts
• Day 2: Let’s break some code!
• Day 3: Coroutines and Modules
• Day 4: Compile-time programming
• Day 5: New Tooling Study Group
• Day 6: Plenary

Dependency Management For C++ -- Hans Klabbers

Dependency management is a missing piece in the C++ eco system.

Dependency Management For C++

by Hans Klabbers

About the article

The writer took part in the developer survey and followed up on the outcome. Depenendency management is seen as a missing piece in the C++ standard. The article is written as a response on a tweet by Bryce Lelbach and an article on medium by Corentin. It describes the author's ideas for dependency management. 

trip report: first ISO C++ meeting experience -- Vittorio Romeo

This trip report covers the author's first ISO C++ meeting experience. Vittorio talks about the most interesting interactions and papers discussed in Jacksonville, while also sharing some of his thoughts regarding controversial topics such as modules and 2D graphics.

trip report: first ISO C++ meeting experience

By Vittorio Romeo

From the article:

I'm back in London from Jacksonville, where I attended my first ISO C++ meeting. Apart from the long flights and long working hours, it has been a very enjoyable experience for multiple reasons: [...]

[...] almost every interaction when debating a paper was very well motivated, and I found myself thinking "that's a very good point" very often, even when two conflicting opinions were being stated one right after the other [...]

Guy Davidson's Jacksonville Trip Report

By Guy | Mar 20, 2018 05:06 AM | Tags: None

Having landed safely in Britain and recovered somewhat from his mystery illness, Guy has prepared a trip report, paying particular attention to the drama of the 2D Graphics paper and the unexpected interruption to the closing plenary.

Oh, lock-free circular buffers, yay! Hey, no 2D graphics? Jacksonville trip report

by Guy Davidson

From the article:

Right now, both library groups are processing fewer papers than they receive. There are 19 sessions of about two hours during each meeting, and LWG spent the first five sessions on P0214, Data-Parallel Vector Types & Operations (for the Parallelism TS), which defines some SIMD types. I was delighted to be in on this, and even offered to scribe but found it impossibly hard, unlike my stint in LEWG at Toronto. However, it was during the fourth of these sessions that I started to feel distinctly unwell.

A good library fro formatting in the standard, soon?

Text Formatting at the ISO C++ standards meeting in Jacksonville

by Victor Zverovich

From the article:

This week I attended the ISO C++ standards committee meeting to present the second revision of my paper P0645R1 Text Formatting, based on the {fmt} formatting library. The first revision was reviewed by Library Evolution Working Group (LEWG) in June 2017 in Toronto and there was a lot of feedback, particularly I’ve been asked to

• investigate compile-time format string processing,
• look at using or explain why not to use an output iterator,
• use string_view,
• allow pre-computation of output size,
• add benchmarks.

It took me a while to address all the feedback, especially the first two items which required substantial API and implementation changes, so I had to skip the meeting in Albuquerque. However, this ultimately resulted in a much better API so I’m grateful to LEWG for the helpful guidance. Despite all the negative press covfefe “design by committee” sometimes works surprisingly well...
