Demo Code for presentation "Contemporary C++ In Action"
This code does not compile without the missing pieces (the precompiled modules mentioned in the code) because it is for educational purposes only. Besides that it is complete.
The missing pieces are:
- Asio, preferably non-Boost Asio
- libav FFmpeg
- SDL2 SDL
- argparse argparse
- modularized standard library
I have forked
plus
- a modularized standard library with a polyfill for the missing, not yet implemented parts: std.module
which contain the necessary changes to compile Asio, SDL, libav, and argparse as modules. My take on the C++ standard library module adds Casey Carter's current implementation of <generator>, plus my implementation of <print> and a partial implementation of C++26's explicit lifetime management P2590 on top of the standard library that comes with the compiler toolset of your choice.
There is also a minimum set of sources from FFmpeg v6.0 to compile module libav. You need to provide the necessary link libraries yourself if you want to build the executable.
