SFML Edition

It could be a nice idea to start breaking into the territory of engine/library specific editions, which are bundled with each programming language.

SFML seems to be a good choice to start with, and it would get bundled with the C++ edition.

The idea is essentially translating current listings into SFML-aware code.

The issue is about creating an SFML edition for the C++ bundle, translating existing listings into SFML-aware code. Start by examining the repository's structure to understand current listings and how they are organized. Look for existing examples in different languages to see the translation pattern. Determine which SFML features are needed and how to integrate them with the existing content.
