I just wish there were better tools for navigating C codebases.
There’s been more than one time where I’m in some large auto tools based project trying to figure something out and there’s a call out to some dependencies I have no idea of.
Also many of the projects lack and sort of documentation or source code commenting. These aren’t someones pet project either. One of them was from a notable name in the open source community and the other one was a de-facto driver in a certain hardware space.
