C++20 Features and Fixes in VS 2019 16.1 through 16.6
by Stephan T. Lavavej
From the article:
We’ve been busy implementing C++20 features in MSVC’s compiler and Standard Library, and migrating the latter to microsoft/STL on GitHub – in fact, we’ve been so busy that we haven’t posted a C++ toolset changelog since the VS 2019 16.0 toolset changelog. So, here are the compiler features and STL features/fixes that have shipped for production use in the last year.
As a reminder, the /std:c++17 and /std:c++latest compiler options are necessary to use C++17 and C++20 features...

With less than two weeks to go before the conference (in fact only one week before the first workshop), we have some big announcements!
Full schedule, Nico Josuttis Keynote and Remo as a platform
by C++ on Sea
From the article:
After evaluating many options, including building our own solution (from component parts), we have settled on a fairly new system called Remo. What we love about Remo is that it's the closest thing we've found to recreating the experience of being at a physical event

Now you can quickly and easily analyze the code for errors right on the godbolt.org site (Compiler Explorer). This feature opens up a large number of new possibilities – from quenching curiosity about the analyzer's abilities to being able to quickly share check results with a friend. Caution – GIFs!
PVS-Studio is now in Compiler Explorer
by George Gribkov
From the article:
If you want to see the output of your program, you can open the execution window by clicking "Add new... - > Execution only" in the code editor (not in the compiler window). In the gif below, you can see the output of the lab work taken from our page about free usage of PVS-Studio by students and teachers.

With recent releases SonarQube and SonarCloud offer expanded compiler support and additional security-related rules.
Improved C/C++ analysis
By Alexandre Gigleux
From the article:
There are tons of C/C++ compilers out there and we always get many requests by many users about additional compilers support. We listened and added the support of 10+ compilers to allow more developers to benefit from our C/C++ rules.
We want to help C/C++ developers to deliver code in production without vulnerabilities and more precisely we want to avoid buffer overflow to be exploited by hackers. This is why we implemented 4 rules looking at APIs that could be badly used and that open the door to buffer overflow attacks

Polymorphic Allocators, std::vector Growth and Hacking
by Bartlomiej Filipek
From the article:
The concept of a polymorphic allocator from C++17 is an enhancement to standard allocators from the Standard Library.
It’s much easier to use than a regular allocator and allows containers to have the same type while having a different allocator, or even a possibility to change allocators at runtime.
Let’s see how we can use it and hack to see the growth of std::vector containers...

Stupid std::tuple tricks: Finding a type in a tuple

One of the ways to improve software quality is to check source code with static analysis tools. This section explains how to use the PVS-Studio analyzer to check projects built on ModernCppStarter. We provide a free license for open-source projects.
ModernCppStarter & PVS-Studio Static Code Analyzer
by PVS-Studio Team
From the article:
plog-converter will convert the report into the errorfile format (similar to GCC's messages), which can be conveniently viewed in a terminal window and the IDE. You can also have the report converted to an HTML file by using the -t fullhtml flag. Use the flags -a and -d to filter diagnostics. Run the plog-converter --help command to view the full list of available options.

Stupid std::tuple tricks: Creating more interesting index sequences
by Raymond Chen
From the article:
Last time, we wrote offset_sequence_t, which takes an existing sequence and adds a fixed value to each element. This is the sort of index manipulation you may want to generalize. So let’s generalize it...

Stupid std::tuple tricks: Creating interesting index sequences
by Raymond Chen
From the article:
We saw last time that manipulating tuples boils down to the index_sequence. The problem is that the C++ standard library doesn’t provide very much in the way of helpers to manipulate these index sequences...
