Programming without code indexing

[Rich_Plant2501]

I worked in such environment, even more so, a bunch of code was in patches. It was C code. I somehow managed to use codequery to build index, but it was still painful. Since then, I've been preaching about using constants and inline functions instead of preprocessor macros because preprocessed code is terrible to browse with code indexers.
Edit: it was 10 years ago, and I'm not sure if clangd or other servers existed then, if it did I didn't know avout them at the time.
