Doxygen unfortunately includes standard library headers in include dependency graphs. This easily clutters it and makes the graph rather unpleasant to look at.
However, there is a way to remedy this: hook into Doxygen and patch the dot files!
- Install pydot using your preferred Python package manager
- Set the
DOT_PATHin your Doxyfile to the hooks/ directory of this repository
Doxygen should now patch all include dependency graphs who have nodes that match a standard library header name or whose nodes link to cppreference if properly set up through Doxygen's tag support.
