We have added a new experimental static analysis rule in Visual Studio 16.10 version Preview 3 - C26458, . The new warning is a more precise and less noisy version of warning C26446, . Both warnings analyse standard containers for unchecked element access and they both share the warning message: “Prefer to use instead of unchecked subscript operat...
MSVC static analysis update for Visual Studio 16.9.
The C++ standards committee is currently focusing on adding features to the language which can simplify code. One small example of this in C++20 is conditionally trivial special member functions, which we added support for in Visual Studio 2019 version 16.8. Its benefit isn’t immediately obvious unless you’ve been deep down the rabbit hole of high-...
Update June 4th, 2020 - GSL version 3.1.0 has been released. Please see the latest release page for information regarding GSL 3.1.0. For all future updates, please see refer to the release page on GitHub. GSL 3.0.0 Release Version 3.0.0 of Microsoft's implementation of the C++ Core Guidelines Support Library (GSL) is now available for ...
The specifier in C++ marks a class or virtual member function as one which cannot be derived from or overriden. For example, consider the following code:Â If we attempt to write a new class which derives from `derived` then we get a compiler error:Â The specifier is useful for expressing to readers of the code that a class is not to be der...
is a C++20 feature for simplifying the implementation of generic types and improving compile-time performance. In C++ it is common to write and use types which wrap objects of other types. and are two examples, but there are plenty of others in the standard library, Boost, and likely your own codebases. Following the principle of least astoni...
This post is part of a regular series of posts where the C++ product team here at Microsoft and other guests answer questions we have received from customers. The questions can be about anything C++ related: MSVC toolset, the standard language and library, the C++ standards committee, isocpp.org, CppCon, etc. Today's post is by Cameron DaCamara. ...
Writing good documentation is hard. Tools can’t solve this problem in themselves, but they can ease the pain. This post will show you how to use Sphinx to generate attractive, functional documentation for C++ libraries, supplied with information from Doxygen. We’ll also integrate this process into a CMake build system so that we have a unified work...

In the previous post in this series, we used clang-query to examine the Abstract Syntax Tree of a simple source code file. Using clang-query, we can prototype an AST Matcher which we can use in a clang-tidy check to refactor code in bulk. This time, we will complete the rewriting of the source code. Let's return to MyFirstCheck.cpp we gen...
