is a C++23 feature that enables you to write concise, straightforward functions that generate sequences of values on-demand without manually managing state. It builds upon C++20’s coroutines, providing some standard library support for this powerful, but complex, language feature. As of Visual Studio 2022 version 17.13, we ship an implementation o...
Overview Introduction In our previous two (part 1, part 2) blog posts we discussed how Office was thinking holistically about header units. In this installment we’d like to share the concrete steps taken to integrate header units into the build of Microsoft Word, and their effect on build throughput. Throughout the...
Back with VS2019 version 16.10, we announced a complete implementation of C++ Modules (and, generally, of all C++20 features) across the MSVC compiler toolset, static analysis, IntelliSense, and debugger. Implementing Modules requires principled intermediate representation of C++ source programs. Today, we are thrilled to announce the availability ...
In this follow-up blog, we will explore progress made towards getting header units working in the Office codebase. Overview Overview Last time we talked about how and why header units can be integrated into a large cross-platform codebase like Office. We discussed how header units helped surface conformance issue...
Details of C++20 support for C++/CLI introduced in VS 2022 17.6
In this blog we will explore one change the MSVC compiler has implemented in an effort to improve the codegen quality of applications in debug mode. We will highlight what the change does, and how it could be extended for the future. If debug performance is something you care about for your C++ projects, then Visual Studio 2022 version 17.5 is maki...
.cameron { color: #4472c4; } C++20 has had a lot to offer and one feature in particular requires the most thought of all when integrating into our projects: C++ modules (or C++ header units in this particular case). In this blog we will show a real world case of integrating a new C++20 feature into a large codebase that we might all...
Find out how C++23's Deducing this feature can help make your code better.
GSL 4.0.0 has been released! Here is a summary of the changes.
There is a lot of hype (and perhaps restraint) to using modules in projects. The general blocker tends to be build support, but even with good build support there is a distinct lack of useful resources for practices around moving projects to using named modules (not just header units). In this blog we will take a small project I created, analyze it...
