> I gave this a shot, but realized the the glob returned the relative path `../docs/clang-tidy/checks/<subdir>/<check>.rst`, and the existing logic only adds `[<subdir>, <check>.rst]` to the list. Python3.10's `glob.glob` has root_dir which would do the trick for us, but I don't think we can rely on Python3 yet? I think using glob might not improve the readability all that much since I'd have to strip out the `docs_dir` subpath, but happy to give that a go based on your feedback.
Good point, I was thinking of something along these lines:


```
from pathlib import Path

for doc_file in map(lambda s: Path(s), glob.glob(os.path.join(docs_dir, "*", "*.rst"))):
  doc_files.append([doc_file.parts[-1], doc_file.parts[-2])
```

The current patch is already a great cleanup so I'm fine with it as well :)
