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...

The “unsigned for value range” antipattern

by Arthur O’Dwyer

From the article:

Background: Signed Integers Are (Not Yet) Two’s Complement
At the WG21 committee meeting which is currently underway in Jacksonville, JF Bastien will be presenting a proposal to make C++’s int data type wrap around on overflow. That is, where today the expression INT_MAX + 1 has undefined behavior, JF would like to see that expression formally defined to come out equal to INT_MIN...

A tough problem.

String’s competing constructors

by Andrzej Krzemieński

From the article:

Let’s start with the problem. I want to check whether a program received a text message that consists of four consecutive zeroes. Not '0', but the numeric zero. I will create a constant std::string representing the special sequence and compare the messages (also stored as std::strings) I receive...
