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...

ACCU 2020 Call for Proposals

By Felix Petriconi | Oct 3, 2019 12:39 PM | Tags: community

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.

Cppcon 2019 Milestone | New Home | Trip Reports--Jon Kalb

Many things happened.

Milestone | New Home | Trip Reports

by Jon Kalb

From the article:

CppCon 2019 was the first year in our new home at the Gaylord Rockies in Aurora, Colorado.

Long before I’d ever done it, I told people that I thought that moving a conference is almost as much work as starting one from scratch. Now that I have moved a conference, I’ve learned that started a conference from scratch is actually easier than moving that conference after it has been growing in one location for five years...

Join the Maryland C++ User Group

By Adrien Hamelin | Oct 2, 2019 11:22 AM | Tags: community

If you live in the area.

Join the Maryland C++ User Group

From the article:

After looking for and failing to find a C++ user group in Maryland, I decided to start one. If you live in the Baltimore/DC/NoVA area, use C++ for work or pleasure, and are interested in attending monthly-ish meetings related to C++, please join the meetup group at https://meetup.com/CppMaryland/. Topics for discussion will include current (C++11/14/17) features, the upcoming C++20 standard, build tools, standard containers and algorithms, design patterns, and pretty much anything else that might benefit a C++ developer...

Alternatives to C++ Function Pointers in SYCL using Function Objects -- Georgi Mirazchiyski

By rodburns | Oct 1, 2019 01:57 PM | Tags: None

This blog post offers an interesting solution for replacing function pointers with function objects and lambdas.

Alternatives to C++ Function Pointers in SYCL using Function Objects

by Georgi Mirazchiyski

From the article:

Function Pointers are a feature of the C language and so form part of the C++ standard. As such, a function pointer allows the following behavior:

    "A pointer to a function can be passed as a parameter to another function"

In C++, especially in modern C++, function pointers are a legacy feature from the C language but they still exist in some code bases.

SYCL enables single source development where template functions can contain both host and device code to construct complex algorithms that use acceleration. However, SYCL does not provide support for function pointers since this is a limitation posed by the design of OpenCL v1.2 which is the basis of the current SYCL v1.2.1 definition.

But there is good news, we can use modern C++ to implement a solution that can be used with SYCL. SYCL is built with C++11 (and onward depending on the implementation), meaning features like anonymous functions known as "lambdas" can be used with little to zero overhead. Even going back to C++98/03 it is possible to use function objects defined as either structs or classes, and additionally, you can template your operation (the computation logic) to provide a generic way to consume the function objects or lambdas.
