QStringTokenizer merged for Qt 6.0

QStringView Diaries: Zero-Allocation String Splitting

by Marc Mutz

From the article:

I am happy to announce that the first QStringTokenizer commits have landed in what will eventually become Qt 6.0.

QStringTokenizer splits strings, with zero memory allocations, universally, and safely.

While the version in Qt will be Qt 6-only, KDAB will release this tool for Qt 5 as part of its KDToolBox productivity suite.

C++20: Further Open Questions to Modules

by Rainer Grimm

From the article:

So far, I have written in my last four posts the basics you should know about modules in C++20. Only a few questions to modules are still open. In this post, I address these open questions, such as templates in modules, the linkage of modules, and header units.

C++20: Structure Modules

By Rainer Grimm

From the article:

When your module becomes bigger you want to divide its functionality into manageable components. C++20 modules offer two approaches: submodules and partitions. Let me discuss both approaches in this post.

How do you use them?

C++ Lambdas, Threads, std::async and Parallel Algorithms

by Bartlomiej Filipek

From the article:

In articles about lambda expression (like this one from last week on my page), it’s easy to show examples where the lambda runs on the same thread as the caller. But how about asynchronous cases? What if your lambda is called on a separate thread? What problems you might encounter there.

Read on and let’s explore this topic...

How to ask for C++ coding help--Kate Gregory

The good practices exist also to ask for help.

How to ask for C++ coding help

by Kate Gregory

From the article:

Lately a lot of people have been asking me for help as they write C++ code. I’m usually happy and able to help. There are times, though, when I either cannot help, or choose not to help. I thought it might be helpful to explain some of these a little. It’s quite likely that other members of the community have a similar set of guidelines in their heads for when they do and don’t help people with code...

From the article:

The mixture of brackets in the preceding line become one of the most noticeable indications of Modern C++.
Yep.
Lambda Expressions!
It might sound like I’m trying to create a new blog post about something that everyone knows. Is that true? Do you know all the details of this modern C++ technique?

In this article, you’ll learn five advantages of Lambdas. Let’s start...

C++20: A Simple math Module

by Rainer Grimm

From the article:

Modules are one of the four prominent features of C++20. They overcome the restrictions of header files and promise a lot: faster build-times, fewer violations of the One-Definition-Rule, less usage of the preprocessor. Today, I want to create a simple math module...

Ray Tracing in one weekend with SYCL

SYCL is an open standard developed by the Khronos™ Group that enables developers to write code for heterogeneous systems using standard C++.

Ray-tracing in a Weekend with SYCL: Basic sphere tracing

by Codeplay

About the article

C++ Ray-Tracing in a Weekend by Peter Shirley is a great resource to start learning about ray-tracers and how to implement one, and at the same time providing all the source code in a GitHub repository . You can find more information about his books on ray-tracing techniques with accompanying implementations on his blog, and you can also download the books as .pdf, or load them on your Kindle device for free from the GitHub project.

The main goal of this blog post is not to teach the concepts of ray-tracing, Peter does a great job of that, but provide a walk-through tutorial on how to accelerate practical applications and algorithms using SYCL.
