C++26 pack indexing lets you grab the Nth type from a pack without recursion. no more std::tuple trickery.

The Pimpl pattern: heap allocate your implementation, write a copy constructor, write a move constructor, write a destructor, write copy assignment, write move assignment C++26: std::indirect<Impl> impl_; Done. The compiler generates everything 🧵👇

This is Algebrica. A mathematical knowledge base I’ve been building for 2.5 years. 215+ entries, carefully written and structured. 400k+ views over this time. Not much in absolute terms, but meaningful to me. No ads. No courses to sell. No gamification. No distractions. Just essential pages, aiming to explain mathematics as clearly as possible, for a university-level audience. Built simply for the pleasure of sharing knowledge. Content licensed under Creative Commons (BY-NC). Best experienced on desktop. If it helps even a few people understand something better, it’s worth it.

Posted a new video about std::chrono which provides an overview of what functionality was added in C++11, C++17, and C++20. Watch to find out how much of chrono your compiler supports. We were pretty surprised at what we discovered. #cplusplus youtube.com/watch?v=63GKRVb8…

Storage duration and Non-local Objects in C++

C++ allows us to declare various forms of non-local objects: they usually live throughout the execution of the whole program. In this article, we’ll look at global variables, dynamic, and thread-lo...

Been playing a lot with CPM lately, and I must say, I'm VERY happy with how it's working out. youtu.be/dZMU3iAPhtI Mostly it comes down to there being no question at all about how dependencies were compiled, because they are all just Right There. Watch the video for cons

I finally managed to write a blog post again: | Configuring algorithms in Modern C++ | hannes.hauswedell.net/post/2… | #cplusplus #cpp @meetingcpp
When designing library code, one often wonders: “Are these all the parameters this function will ever need?” and “How can a user conveniently change one parameter without specifying the rest?” This post introduces some Modern C++ techniques you can use to make passing configuration options easy for your users, while allowing you to add more options later on.

Have a look at my article on Ranges and Projections: cppstories.com/2023/projecti… Do you have more examples? Join the discussion in the article :) #programming #cpp #cpp20

Examples of Projections from C++20 Ranges

C++20 Ranges algorithms have an excellent feature called “Projection”. In short, it’s a callable applied on each range element before further processing. In this article, I’ll show you a couple more...

TIL about `const T (&... x)[N]` (aka passing variadic arguments has never been easier)

This is cheating a bit, but it technically works: compiler-explorer.com/z/1TxG…

Compiler Explorer - C++ (x86-64 gcc 12.2)

struct Point { int i,j; }; template static void foo(const Ts ...x) { } template static void foo(const Ts (&... x)[2]) { foo(Point{x[0],x[1]}...); } int main() { foo({1,2},{3,4}); foo({1,2},{3,4},{5...
