What's in C++20 and the C++17 final score card

What's in C++20 and the C++17 final score card: A report from Kona and look at the Toronto C++ meeting
Posted on July 10, 2017 by Michael Wong.

I am writing this blog long after my trip to the Kona C++ standard meeting due to unusually high business commitments post-meeting and using it as an opportunity to also look ahead to the C++20 content to be reviewed in Toronto. I will publish my usual update to the C++17 content slidedeck similar to my Dec 2016 Issaquah trip report. This will contain the final score card for C++17, including all the features with links, and an evaluation scorecard of what made it in based on what Bjarne had earlier suggested in 2015 as possible content for C++17.

CppCon 2016: C++ Coroutines: Under the covers--Gor Nishanov

By Adrien Hamelin | Jul 12, 2017 12:05 PM | Tags: experimental efficiency

Have you registered for CppCon 2017 in September? Don’t delay – Registration is open now.

While we wait for this year’s event, we’re featuring videos of some of the 100+ talks from CppCon 2016 for you to enjoy. Here is today’s feature:

C++ Coroutines: Under the covers

by Gor Nishanov

(watch on YouTube) (watch on Channel 9)

Summary of the talk:

Coroutines feel like magic. Functions that can suspend and resume in the middle of the execution without blocking a thread! We will look under the covers to see what transformations compilers perform on coroutines, what happens when a coroutine is started, suspended, resumed or cancelled. We will look at optimizations that can make a coroutine disappear into thin air.

Future Ruminations -- Sean Parent

This post is a lengthy answer to a question from Alisdair Meredith via Twitter

Future Ruminations

by Sean Parent

From the article:

The question is regarding the numerous proposals for a better future class template for C++, including the proposal from Felix Petriconi, David Sankel, and myself.

It is a valid question for any endeavor. To answer it, we need to define what we mean by a future so we can place bounds on the solution. We also need to understand the problems that a future is trying to solve, so we can determine if a future is, in fact, a useful construct for solving those problems.

The proposal started with me trying to solve a fairly concrete problem; how to take a large, heavily threaded application, and make it run in a single threaded environment (specifically, compiled to asm.js with the Emscripten compiler) but also be able to scale to devices with many cores. I found the current standard and boost implementation of futures to be lacking. I open sourced my work on a better solution, and discussed this in my Better Code: Concurrency talk. Felix heard my CppCast interview on the topic, and became the primary contributor to the project.

Playing with C++ Coroutines--Sumant Tambe

An old presentation about coroutines:

Playing with C++ Coroutines

by Sumant Tambe

From the article:

While looking for some old photos, I stumbled upon my own presentation on C++ coroutines, which I never posted online to a broader audience. I presented this material in SF Bay ACCU meetup and at the DC Polyglot meetup in early 2016! Yeah, it's been a while. It's based on much longer blogpost about Asynchronous RPC using modern C++. So without further ado...

It had to be done - Abusing co_await for optionals--redditsoaddicting

It had to be done - Abusing co_await for optionals

by redditsoaddicting

From the article:

I finally got around to playing with coroutines in the context of non-future types. I always guessed this could be done. For optionals specifically, the idea is that you do auto x = co_await foo(); and either x is the value in the optional or the function immediately returns an empty optional...
