You may wonder how my day looks. Let me compare a day before ALS with a current day >> My ALS Journey so far << A typical Day My day before ALS is not so exciting. A table will do the job. Currently, all has changed. Now, I have 24/7 support from 4 nurses, together […]
Today, I continue my journey through reflection in C++26 and play with enums and classes. The names of the metafunctions to access an Enum or a Class member are often identical. Access the Members of an Enum The following program is based on one by Daveed Vandevoorde. Daveed is one of the fathers of reflection, […]
Reflection offers many metafunctions that run at compile time. The metafunctions are declared as consteval. consteval creates a so-called immediate function. Each invocation of an immediate function creates a compile-time constant. To say it more directly. A consteval (immediate) function is executed at compile-time. Read more about consteval and constinit in my previous post: Two […]
After the search into the breadth starts today, the search into the depth: reflection. Reflection Reflection is the ability of a program to examine, introspect, and modify its structure and behavior. Reflection in C++ is more. Here are two statements from the proposal (P2996R5). “We not only want to observe the structure of the program: […]
Today, I will finish my overview of C++26 and write about concurrency. There are still two library features left before I jump into the concurrency: saturation arithmetic and debugging support. Saturation Arithmetic Saturation arithmetic is a version of arithmetic in which all operations, such as addition and multiplication, are limited to a fixed range between […]
My ALS progression seems to slow down, and Beatrix and I can the first time plan for the future. >> My ALS Journey so far << How to Approach a Cat? There are two ways to approach a cat: first, you feed it something, and second, you play with it. I’m sad to say that […]
The most interesting feature of the new C++26 standard library is its improved math support. std::submdspan std::submdspan is a subspan of an existing span std::mdspan (C++23). The subspan was not included in C++23 and was added with C++26. Before I continue with C++26, I need to make a brief detour to C++23. std::mdspan A std::mdspan […]
In my last post, I overviewed C++26’s core language. Today, I continue with the library. To make it short. The library does not offer such powerful features as the core language. Let me name them and give you a short example directly from the proposal. std::string and std::string_view Processing The functions around std::string and std::string_view […]
C++26 has a lot to offer. Let me directly jump in and give you an overview. This image gives you the first idea of what’s inside or outside C++26. Writing a blog post about the future is always challenging because the design freeze of C++26 is in the first quarter of 2025. Fishing in Murky […]
C++26 will be the next C++ standard after C++23. This new standard significantly improves C++ and is probably similar game-changing like C++98, C++11, or C++20. Let me put the C++ standards into historical context to help you understand this next step in the evolution of C++. The C++ Standards C++ is more than 40 years […]
