gitignore

[stephen-willoughby]

Bug Description

A description of the bug
We have some gitignore files which add a * to ignore everything and then add back in explicitly what they need with e.g. ! README.md. depcheck doesn't seem to honour these nots and so complains of unused dependencies despite being used

e.g.

# Start by disallowing everything
*
# Now allowlist what we actually want
!thing/
!stuff/
!config/

Code snippets

Extra info

Any extra info you want to include. Thank you for the bug report!

BONUS POINTS: If you wish to help us debug further, the depcheck --json option will show more information. Check here in the README for documentation on json output.

have found can work around with the creation of an empty .depcheckignore

[znarf]

depcheck use the npm package ignore which implements the .gitignore spec fully.

I guess there is something else going on, please give a full reproduction so someone can have a look.
