Expressing fire-and-forget coroutines more explicitly, -or- How to turn any coroutine into fire-and-forget
by Raymond Chen
From the article:
Last time, we looked at how to mark a coroutine as fire-and-forget, meaning that the caller does not get any information about when the coroutine completes. This is fine as far as it goes, but it may not be what you want...

Trip Report: C++ Standards Meeting in Kona, February 2019
by Botond Ballo
From the article:
A few weeks ago I attended a meeting of the ISO C++ Standards Committee (also known as WG21) in Kona, Hawaii. This was the first committee meeting in 2019; you can find my reports on 2018’s meetings here (November 2018, San Diego), here (June 2018, Rapperswil), and here (March 2018, Jacksonville). These reports, particularly the San Diego one, provide useful context for this post...

winrt::fire_and_forget was too forgetful
by Raymond Chen
From the article:
C++/WinRT provides a handy helper class called winrt::fire_and_forget. It lets you specify that nobody is going to observe the result of the coroutine. This is handy because it lets you tell the compiler that the lack of observation is intentional, so it won’t generate a warning...

Macro Evil in C++ Code
by Andrey Karpov
From the article:
The C++ language opens extensive opportunities to go without macros. So let’s try to use macros as seldom as possible!

Quick A: each release of C++ allows more things to be done at compile time.
Recently on SO:
Compile-time loop optimisation
In C++14, constexpr function requirements were relaxed.
Previously, in C++11, constexpr functions could only contain typedefs, static_asserts and usings, but only a single return statement.
In C++14, it became possible to use loops in constexpr function bodies.
Because b was declared as constexpr char, it must be evaluated at compile time. The compiler then optimised out the isStringNice function, as it is not used at run time.

Game performance and compilation time improvements in Visual Studio 2019
by Gratian Lup
From the article:
The C++ compiler in Visual Studio 2019 includes several new optimizations and improvements geared towards increasing the performance of games and making game developers more productive by reducing the compilation time of large projects. Although the focus of this blog post is on the game industry, these improvements apply to most C++ applications and C++ developers...

How do I design a class so that methods must be called in a certain order?
by Raymond Chen
From the article:
Suppose you have a class with some methods, and the methods must be called in a certain order. For example, suppose your class is for importing photos from a camera. First, you have to specify which camera you are importing from. Then you discover the pictures. Then you have to select which pictures you want to import, and set the options for how you want the download to occur. And finally, you download them...

C++ Insights - Implicit Conversions
by Andreas Fertig
From the article:
This series is motivated by a brief conversation I had with Andreas. I asked him if he has some use case examples which show how C++ Insights can be helpful when teaching. I think there are many things. This article is the start of a series of five posts by Andreas which I will publish at Modernes C++ because I think C++ Insights is an invaluable tool to get a deeper insight in the C++ compiler magic. In case, you are new to C++ Insights consider this introductory article. Without further ado, Andreas post. When you follow the link near to each example, you can directly analyse the example in C++ Insight...
