Small utility quickly made to generate Mermaid class diagram directly from cpp source files To use it just edit the path and the blacklist in main.cpp and run !
The code is awful but i needed it fast to submit a beautiful graph for a school project. It is quite buggy as it doesn't parse well operator functions nor global variables (anything declared outside a class).
There are plenty of better alternatives out there i didn't find at the time such as clang-uml or hpp2plantuml
