C++20 Coroutine: Under The Hood
by Vishal Chovatiya
From the article:
A coroutine is one of the major feature introduced with the C++20 standard apart from Module, Ranges & Concept. And you see how happy I am to unfold it. I already set the baseline on this topic with my previous article that Coroutine in C Language, where we saw, how suspension-resumption of execution works! With this article “C++20 Coroutine: Under The Hood”, we will see how compiler creates magic & standard library helps it with basic infrastructure making C++20 coroutine more sophisticated(yet complex) & scalable/customizable...

Report from the virtual ISO C++ meetings in 2020 (core language)
by Jason Merrill
From the article:
C++ standardization was dramatically different in 2020 from earlier years. The business of the International Organization for Standardization (ISO) committee all took place virtually, much like everything else during this pandemic. This article summarizes the C++ standardization proposals before the Core and Evolution Working Groups last year...

C++ coroutines: Promise constructors
From the article:
So far, all of our coroutine promises have had only a default constructor. But the standard actually gives the promise access to the coroutine parameters, if it wants them...
A map through the three major coroutine series
From the article:
Our long national nightmare is not yet over: The three main coroutine series are now done, although that doesn’t mean I’m done with coroutines.Here’s a map through the main series, at least. There is a direct route and a number of scenic routes...
A subtle way your await_suspend can access the coroutine frame when it shouldn’t
From the article:
As we learned in the very start of the series on coroutines, the await_suspend method cannot access the coroutine frame once it arranges for the coroutine to resume because that creates a race condition where the coroutine might already be resumed and possibly even run to completion before await_suspend finishes...

Templates - First Steps
by Rainer Grimm
From the article:
The idea of this post is quite simple. I want to visualize templates and, in particular, the process of template instantiation. Thanks to C++ Insights, this visualization is pretty easy...

C++20 Concepts - a Quick Introduction
by Bartlomiej Filipek
From the article:
Concepts are a revolutionary approach for writing templates! They allow you to put constraints on template parameters that improve the readability of code, speed up compilation time, and give better error messages.
Read on and learn how to use them in your code!

C++ coroutines: Converting among tasks that use the same promise
by Raymond Chen
From the article:
If the only difference between tasks is in the awaiter, then it’s possible to convert between them without the promise even knowing what happened. We have an example of this with our simple_task and com_simple_task, which differ only in the awaiter produced by the co_await operator. This means that we can actually convert between the two by simple wrapping the promise inside the other class...

The monthly overview of upcoming C++ User Group meetings!
Online C++ User Group Meetings in May 2021
by Jens Weller
From the article:
The monthly overview on upcoming C++ User Group meetings. A bit later then usual, seems my talk at C++now and announcing Meeting C++ 2021 has kept me a bit too busy.
Next week Tuesday: Meeting C++ online - May - Design Patterns - Facts and Misconceptions with Klaus Iglberger. If you're interested in this topic, Klaus also gives a training on Modern C++ and Design Patterns in June.

C++ coroutines: Waiting synchronously for our coroutine to complete
by Raymond Chen
From the article:
Last time, we added an extension point that permitted us to respond differently to the completion of the coroutine. We’re going to put that extension point to good use by adding the ability to wait synchronously for the coroutine to complete.

C++ coroutines: Adding COM context support to our awaiter
by Raymond Chen
From the article:
You may want to have awaiters that apply custom resume behavior. For example, in Windows, you are likely to want your awaiter to preserve the COM thread context. For X11 programming, you may want to the awaiter to return to the render thread if the co_await was initiated from the render thread. Today we’ll add the ability to customize the awaiter to our coroutine promise type...
