Beta-Testing of PVS-Studio Plugin for JetBrains CLion

By Andrey Karpov | Jun 29, 2021 05:27 AM | Tags: static code analyzer sast pvs-studio jetbrains clion

To fully test the plugin, you'll need to install both the beta plugin version and the C++ core beta version of the analyzer. There are several ways to install the plugin: from the official repository, from the repository on our site, or using Windows PVS-Studio installer. Below we'll tell you in detail how to do this.

Beta-Testing of PVS-Studio Plugin for JetBrains CLion

by Evgeniy Ovsyannikov, Paul Eremeev

From the article:

We usually recommend running full analysis regularly, such as once a day, at night. In addition to nightly analysis, we highly recommend checking new code immediately after writing it. This way you'll get the best advantage of using the analyzer. To do this, use incremental analysis, which works as follows. A project was changed, a developer runs a build. After successful compilation only modified files will be analyzed. Modified files are the ones that have been changed since the previous analysis.

Template Argument Deduction of Class Templates--Rainer Grimm

The series continue.

Template Argument Deduction of Class Templates

by Rainer Grimm

From the article:

In my last post Template Arguments, I wrote about function template type deduction (C++98) and auto type deduction (C++11). Today I wear more modern hats. I start with automatic type deduction of non-type template parameters and class templates (C++17) and finish with automatic type deduction of concepts (C++20).

Reversing words of a string with ranges--Marco Arena

A new interpretation of a classical problem:

Reversing words of a string with ranges

by Marco Arena

From the article:

In this post I share the story of a “C++ aha-moment”, hence I use the hashtag #thatsarotate (resumed last Saturday at the Italian C++ Conference 2021 to honor our keynote speaker Sean Parent). Why not sharing your own stories of “C++ aha-moments” adding the same hashtag to your tweets, posts, or whatever? It would be really appreciated...

In this guest blog post, Greg will share a few top tips for debugging C++ code.

7 Top Tips for Debugging C++

by Greg Law

From the article:

Debugging is central to programming – you cannot be a great programmer without being great at debugging. Hopefully, my favorite C++ debugging tips will help you be as clever and productive debugging your code as you are writing it in the first place.

  • #1 Have a full kit of debugging tools
  • #2 Conditional breakpoints
  • #3 Watchpoints
  • #4 User-defined debugging commands in Python
  • #5 Pretty-print structures
  • #6 Time Travel Debugging
  • #7 Command find to search for a byte sequence

Transrangers: An Efficient, Composable Design Pattern for Range Processing -- Joaquín M López Muñoz

Another twist on ranges.

Transrangers: An Efficient, Composable Design Pattern for Range Processing

by Joaquín M López Muñoz

From the article:

Transrangers are a new design pattern for efficient, composable range processing that can be faster than pull-based C++/Range-v3 views whithout losing any expressiveness. The underlying architecture combines ideas from push processing with the internalization of control flow. Transrangers can be used on their own or be leveraged as an implementation detail of range libraries to improve the performance of view-based operations.

In collaboration with Digital Medium, we've produced a video to showcase this year's event (ok, it was mostly Digital Medium, with some input from us)!

CopperSpice: char8_t

New video on the CopperSpice YouTube Channel:

char8_t

by Barbara Geller and Ansel Sermersheim

About the video:

In this video we look at the new definition of char8_t in C++20. Since most developers use strings in their code, this is a big deal. This change caused a cascade and a ripple effect. Our video explains the controversy, confusion, and how your code will be affected.

Painless C++ Coroutines--Gajendra Gulgulia

Another introduction.

Painless C++ Coroutines-Part 1

Painless C++ Coroutines-Part 2

Painless C++ Coroutines-Part 3

Painless C++ Coroutines-Part 4

Painless C++ Coroutines-Part 5

by Gajendra Gulgulia

From the article:

Incidentally I found the mechanics of coroutines quite obfuscating given the number of implicit and under-the-hood calls to several methods associated with coroutine and their return type objects. Even with tons of articles and posts on the web, I started to have a feeling that coroutines is an arcane feature that can be understood by the very few who are either in committee or are renowned authors of blogs, books and articles or experienced C++ library authors.
But after a month of arduous efforts and experiments, trials and errors to understand coroutine, I decided to write a tutorial series that can be used by any intermediate C++ developer to understand coroutine and in the effort I made sure that this article is the last that anyone should refer to, to learn, understand and demystify coroutines without being a super experienced C++ library author. If you’re impatient to get started, then directly jump to section 1: What are coroutines? Else read the Introduction section to get detailed highlight of the tutorial series...
