WG21 pre-Jacksonville telecon minutes
by Jonathan Wakely
By Blog Staff | Mar 7, 2018 04:39 PM | Tags: None
From last Monday through this Monday, we ran our first global C++ developer survey.
Thank you to the over 3,200 of you who responded. As promised, here is a public summary of the results:
Results summary: C++ Developer Survey "Lite": 2018-02
This summary has now been forwarded to the C++ standards committee, along with the full text of your write-in answers (over 300 pages!). Your feedback will be very helpful, and has already started to be referred to by standards participants as we prepare for next week's ISO meeting in Jacksonville, FL, USA.
Thank you again for your participation. It is very helpful, and based on the success of this survey we plan to run it again in the future from time to time. When we do, it will be announced here on isocpp.org.
Note: Due to a SurveyMonkey bug, the word clouds showing popular keywords for the five open-ended questions cover about half the responses, which fortunately is still a large sample. They're working on a fix to include all the responses in the word clouds.

WG21 telecon meeting: Modules TS publication
by Jonathan Wakely
Excerpt:
Single poll meeting, deferred from end of the previous meeting to allow Modules TS wording to be completed.
By Blog Staff | Feb 26, 2018 11:47 AM | Tags: None
Today the Standard C++ Foundation opened its first-ever global C++ developer survey. As the name suggests, it's a one-pager:
C++ Developer Survey "Lite": 2018-02
Please take 10 minutes or so to participate! A summary of the results, including aggregated highlights of common answers in the write-in responses, will be posted publicly here on isocpp.org and shared with the C++ standardization committee to help inform C++ evolution.
If this one is successful we plan to do it again, perhaps annually or quarterly.
Thank you for participating and helping to inform our committee and community.

With the next standardisation meeting coming up, now is a good time to consider what the limits of the standard library should be.
Batteries not included: what should go in the C++ standard library?
By Guy Davidson
From the article:
About forty Christmases ago I was absolutely delighted to open a slot car racing set from my parents. I feverishly set everything up, created a track reminiscent of Brands Hatch, and went to plug everything in, only to discover that I needed batteries to operate the controllers. This was Great Britain in the 1970s...

Working Draft, Extensions to C++ for Modules
by Gabriel Dos Reis
Excerpt:
As approved between meetings as a current working draft base for further proposal discussion in Jacksonville.

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...

Red Hat at the ISO C++ Standards Meeting (November 2017): Parallelism and Concurrency
by Torvald Riegel
From the article:
Several Red Hat engineers attended the JTC1/SC22/WG21 C++ Standards Committee meetings in November 2017. This post focuses on the sessions of SG1, the study group on parallelism and concurrency. SG1 had a full schedule as usual, with Executors, Futures, and deferred reclamation mechanisms (e.g., RCU) being major discussion topics. We also started to track the state of proposals and topics we will need to discuss in a publicly accessible bug tracker...
