Quo Vadis – Modernes C++

DONE: I have written almost 100 posts about C++20. Now, I want to ask you: What should be my next big topic? Make your choice in this poll.

First of all, here is an overview of my more than 300 posts, including C++20.

Now, let me take about the future of Modernes C++. I have three ideas: C++23, extending and embedding Python with C/C++, and templates. The poll is open for one week, including the 24.04. This means, in my next post I present your favourite and my plan to write about it.

Maybe, you don’t know what to choose. Here is more information about each topic.

C++23

C++20 is just the starting point. There is work to be done in C++23 to fully integrate and use the potential of the Big Four in C++. Let me give you a few ideas about the near C++ future.

The Standard Template Library was designed by Alexander Stephanov with concepts in mind. Still, the integration of concepts is missing in C++20.
We can expect a modularized Standard Template Library and hope for a packaging system in C++.
Many algorithms known from functional programming are still missing in the ranges library. A future C++ standard should improve the interplay of the range algorithms and the standard containers.
We don’t have coroutines. We only have a framework for building powerful coroutines. A coroutines library will be, with high probability, in C++23.

Ville Voutilainen’s proposal P0592R4 “To boldly suggest an overall plan for C++23” gives a first idea of the upcoming C++23 standard. Ville names seven features.

Extending and Embedding Python with C/C++

Python is very communicative. On the one hand, it is very easy to call C/C++ functionality from Python (extend), and on the other hand, Python can be used directly from a C/C++ runtime (embed). Extend allows you to offload performance-critical parts of your program to C/C++. Thanks to embedding a Python interpreter in your C/C++ application, the C/C++ application has a scripting interface.

A few days ago, I gave a German presentation at the EnterPy2021 about extending and embedding Python with C/C++. Here is the presentation.

Templates

The future of C++ speaks templates. Sadly, most C++ professionals don’t know templates sufficiently well enough. My idea is to provide you with the details about templates. Here is my rough plan:

Basics
- Function templates
- Class templates
- Template parameters
- Template arguments
- Specialization
Details
- Template Instantiation
- Variadic Templates
- Fold Expressions
- Friends
- Dependent Names
Techniques
- Automatic return type
- Template metaprogramming
- Type traits
- constexpr
- constexpr if
Design
- Static versus dynamic polymorphism
- CRTP (curiously recurring template pattern)
- Expression templates
- Idioms and patterns
C++20
- Concepts

Guest Posts

if you want to write an interesting post about C++, I’m happy to publish it on my blogs. This means I publish it on my German and English blogs. You can write it in your mother tongue. I translate it into the another language. You can expect 10.000 – 100.00 readers.

What’s next?

Depending on your choice, I present in my next post a detailed plan about my future posts.
