Support for C++20’s Concepts in CLion

by Anastasia Kazakova

From the article:

Concepts are one of the biggest features coming in C++20, and knowing that, we’ve been thinking about supporting Concepts in CLion for quite a while. Enter Saar Raz with his C++20’s Concepts implementation in Clang! Long story short, we have been collaborating with Saar to merge his branch into our custom Clangd-based language engine in CLion, and started implementing some nice IDE features on top. Sounds ambitious enough, but we have thoroughly enjoyed the experience so far! A very early result of this collaboration was used by Saar in his CppCon 2019 talk on Concepts...

AddressSanitizer (ASan) for Windows with MSVC--Augustin Popa

Will you try it?

AddressSanitizer (ASan) for Windows with MSVC

by Augustin Popa

From the article:

We are pleased to announce AddressSanitizer (ASan) support for the MSVC toolset. ASan is a fast memory error detector that can find runtime memory issues such as use-after-free and perform out of bounds checks. Support for sanitizers has been one of our more popular suggestions on Developer Community, and we can now say that we have an experience for ASan on Windows, in addition to our existing support for Linux projects...

Code analysis with clang-tidy in Visual Studio--Eli Fessler

The safest safety comes from the tools.

Code analysis with clang-tidy in Visual Studio

by Eli Fessler

From the article:

Visual Studio 2019 version 16.4 Preview 1 brings a significant improvement to the C++ code analysis experience: native support for clang-tidy, a Clang-based “linter” tool developed by the LLVM Project that delivers a variety of code improvements such as modernization and standards conformance, static analysis, and automatic formatting...

For professors' note: use PVS-Studio to get students familiar with code analysis tools

We provide several options for free PVS-Studio licensing, including the ones for open projects. Specifically for educational purposes, in case if student's works aren't open, the best option is to add the following comment to the code.

For professors' note: use PVS-Studio to get students familiar with code analysis tools

by Andrey Karpov

From the article:

The PVS-Studio analyzer can be regarded as a fine example of a modern static code analysis tool. First, it's a great example to show the abilities of static analysis tools in detecting errors and security defects. Second, you can demonstrate its integration into the software development cycle to enable continuous code control. In its example, you can show integration with such systems as Jenkins, TeamCity, Azure DevOps, SonarQube, Travis CI and others.

Open Sourcing MSVC's STL

Just announced at CppCon:

Open Sourcing MSVC's STL

From the announcement:

Today at CppCon 2019, we (the MSVC team) announced that we’re releasing our implementation of the C++ Standard Library (also known as the STL) as open source.

https://github.com/microsoft/STL is our new repository, containing all of our product source code, a new CMake build system, and a README with more information. As it explains, we’re still working on migrating to GitHub. While you can clone and build the code right now, there are several things we need to do (like adding our test suites) before we can begin reviewing pull requests.

Q: Why are you doing this?

A: There are several reasons. ...

C++20 Concepts Are Here in Visual Studio 2019 version 16.3

Compiler and library support for concepts is now available in Visual Studio 2019.

C++20 Concepts Are Here in Visual Studio 2019 version 16.3

by Xiang Fan

From the article:

C++20 Concepts are now supported for the first time in Visual Studio 2019 version 16.3 Preview 2. This includes both the compiler and standard library support.

First, we’re debuting the feature via /std:c++latest mode and once we have all C++20 features implemented across all Visual Studio products (compiler, library, IntelliSense, build system, debugger, etc.), we’ll provide them through a new /std:c++20 mode.

PVS-Studio 7.04

PVS-Studio is a tool designed to detect errors and potential vulnerabilities in the source code of programs, written in C, C++, C#, Java. It works in Windows, Linux, and macOS environment.

PVS-Studio 7.04

by Svyatoslav Razmyslov

From the article:

When working on a task developers take code from so many various places. A popular source of Copy-Paste code is the Stackoverflow website and similar ones. There are cases when a developer takes the code from an open source project and doesn't check license requirements. Thus, a closed source project may accidentally get a few files from an open source project with a Copyleft license, which obliges to make the entire project code open source. In companies with a large number of employees, it's difficult to keep track of this, whereas such actions might cause adverse risks and problems. So, PVS-Studio now has a diagnostic, which will help to find such files. It relates to all supported languages (C, C++, C#, Java). The diagnostic is looking for the following "virus" licenses: AGPL-3.0, GPL-2.0, GPL-3.0, LGPL-3.0.
