QStringView Diaries: Zero-Allocation String Splitting

by Marc Mutz

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

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.

A Note of Caution about Using PVS-Studio on godbolt.org (Compiler Explorer)

by Andrey Karpov

This may be promising from the perspective of satisfying one's curiosity, writing articles, and so on. But there's a downside to it too: rather than using synthetic examples to explore or try out the tool, people may start relying on them to evaluate and compare it against other analyzers. And this is a very bad approach because the results will be unreliable and dependent on how the test examples are written.

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

How to ask for C++ coding help

by Kate Gregory

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...
