CopperSpice: std::variant

New video on the CopperSpice YouTube Channel:

std::variant

by Barbara Geller and Ansel Sermersheim

About the video:

In this video, we discuss the std::variant class and its relationship to C++ unions. We explore the drawbacks and constraints of the union abstraction in C++, how they changed in C++11, and how variant addresses many of these shortcomings.

How to Merge Consecutive Elements in a C++ Collection--Jonathan Boccara

Simple and sweet.

How to Merge Consecutive Elements in a C++ Collection

by Jonathan Boccara

From the article:

Merging identical consecutive elements in a collection is a recurring need, in C++ or elsewhere in programming.

For example, we could want to aggregate a collection of hourly results into a collection of daily results: all the results of each day get aggregated into one for that day. In this case, being “identical” means being on the same day, and “aggregating” means taking two results with a common date, and creating a result at this date and with the sum of their amounts...

Overload 153 is now available

ACCU’s Overload journal of October 2019 is out. It contains the following C++ related articles.

Overload 153 is now available

From the journal:

Predictions and Predilections.
Forecasting the future is difficult. Frances Buontempo has a foreboding sense that a lack of impartially makes things even harder.

Scenarios Using Custom DSLs.
Natural-language BDD can be hard to maintain. Liz Keogh demonstrates a simple code-based alternative.

OOP Is not Essential.
People tend to love or hate Object Oriented Programming. Lucian Teodorescu considers a recent OOP claim.

I Come Here Not to Bury Delphi, But to Praise It.
What helps a programming language gain traction? Patrick Martin remembers why he used to use Delphi.

C++ Pipes.
Expressive code can make life easier. Jonathan Boccara demonstrates fluent pipelines for collections in C++.

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.

ACCU 2020 Call for Proposals

The ACCU 2020 is now putting together its program, and they want you to speak on C++. The ACCU has strong C++ tracks, though it is not a C++-only conference. If you have something to share, check out their

Call for Proposals

by the ACCU

About the conference:

Historically, ACCU has a lot of C++ and C content, and is proud of that: ACCU is the foremost annual conference for people interested in C++ and C, at least in and around the UK. But it is not just a C++ and C conference, ACCU is about programming in whatever language people are using, with whatever tools and processes people are using: D, Chapel, Java, Kotlin, C#, F#, Groovy, Rust, Go, Python, Ruby, Lisp, to name just a few programming languages about which there have been sessions at ACCU conferences. Git, Mercurial, CMake, Meson, TDD, BDD, allthese tools and techniques have been the focus of sessions at ACCU. The ACCU Conference is looking for sessions that will be interesting to people who create software.

The ACCU Conference is put on by ACCU (https://accu.org), but is open to anyone who wishes to be there either as a presenter or an attender.

The Call for Papers lasts for about 3 weeks and will close on Friday 2019-10-25 23:59+01:00.
