Game performance and compilation time improvements in Visual Studio 2019—Gratian Lup

Getting better!

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...

C++ Insights - Implicit Conversions—Andreas Fertig

A good tool!

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...

Understanding GCC warnings—Martin Sebor

In detail.

Understanding GCC warnings

by Martin Sebor

From the article:

Most of us appreciate when our compiler lets us know we made a mistake. Finding coding errors early lets us correct them before they embarrass us in a code review or, worse, turn into bugs that impact our customers. Besides the compulsory errors, many projects enable additional diagnostics by using the -Wall and -Wextra command-line options. For this reason, some projects even turn them into errors via -Werror as their first line of defense. But not every instance of a warning necessarily means the code is buggy. Conversely, the absence of warnings for a piece of code is no guarantee that there are no bugs lurking in it...

C++ Core Guidelines: Mixing C with C++—Rainer Grimm

Mixing C and C++ from the point of view of a C++ engineer.

C++ Core Guidelines: Mixing C with C++

by Rainer Grimm

From the article:

The chapter in the C++ core guidelines is called: C-style programming. Honestly, my first thought was to skip it, but after more thoughts I decided to write about it. My reason is twofold:

  1. This are the typical issues we have when dealing with legacy code.
  2. One reader wanted that I write more about the challenges of legacy code.

Trip report: February 2019 ISO C++ committee meeting, Kona, Hawai’i—Timur Doumler

Another report.

Trip report: February 2019 ISO C++ committee meeting, Kona, Hawai’i

by Timur Doumler

From the article:

What better way to start my new blog than to publish a trip report from the most recent C++ committee meeting on the wonderful Big Island of Hawai’i?

If you are looking for an incredibly detailed report of everything that happened, please instead head to this report by Bryce and others, and also see Herb Sutter’s and cor3ntin’s reports. I won’t try to provide this breadth of coverage, and instead focus on a few areas that are particularly relevant for me and the community that I am proxying here:

  • Making C++ simpler, more uniform, and easier to teach;
  • Providing developers with better tools;
  • Improving support for low-latency and real-time(-ish) programming,
  • 2D Graphics, Audio, and other forms of I/O and human-machine interaction.

That being said, let’s start with the big news: we voted both Coroutines and Modules into C++20!

Formatting user-defined types with {fmt} library—Wojtek Gumuła

The future.

Formatting user-defined types with {fmt} library

by Wojtek Gumuła

From the article:

C++ has two standardized ways of printing formatted text out already: printf-family functions inherited from C and I/O streams abstraction built on operator<<. Streams are considered more modern, providing type-safety and extensibility functionalities. However, printf have some notable advantages, too — at the cost of lost type-safety, user can use an interface that looks familiar to almost all developers, allowing for some ways of localization and more readable syntax. And then, there is {fmt} — yet another text formatting library, inspired by design already available in languages like Python and Rust...
