The entry .* in the gitignore breaks the analysis of the whole repository

[stefanmeschke]

When having the entry .* (to ignore all dot files) in the .gitignore file the cli does not find any flag usage.

Please let me know when you need more information.
Thanks in advance!

@stefanmeschke thank you for reporting this issue. Can you share which version you're using and any output that you get when you running the tool?

[stefanmeschke]

Thanks for the quick response! 🙏

As far as I can see there is nothing special in the output. I've replaced all files with <FILE>.

@stefanmeschke Thank you for sharing!

just to clarify - when you run this without .* in the gitignore, how many flags are found in how many files?

[stefanmeschke]

When running this without the ignore then all flags in all files which are referencing flags are found.

[jazanne]

@stefanmeschke thank you for your patience as we looked into this issues.

The behavior you see is a result of underlying differences between gitignore and unix glob matching

Can you try updating your .gitignore file to remove .* and use the following pattern instead?

.[!.]*

[jmgawecki]

Hey there, facing similar issue but when using .ldignore:

# Ignore all files
[!.]*
# But exclude the desired file
!/Modules/Dir/FeatureFlags.swift

This simply disregards everything and scans all the files

[jazanne]

@jmgawecki I think there are two things probably happening here

1. You are seeing Scanning logs (similar to those above) that are actually happening during extinction search. There is a known issue where ignores are not respected during that phase of the pipeline (See: .ldignore file doesn't work for extinction searching #319)

2. The file you want to be scanned !/Modules/Dir/FeatureFlags.swift isn't being scanned because the whole directory is being skipped by pattern [!.]*. This does seems to be a bug and I'll report it to team.

In the meantime, are you able to share more info about why you only want to scan one file for code references? This isn't something we've encountered before and I'd love to know more about your use case.
