GitHub is saying the codeowners file contains errors, may need discussion.

I think it'd be nice if someone volunteered to maintain the examples/ directory or else find a way to greatly simplify it #1973.

Where do you see the GitHub errors?

[notmandatory]

I added / to end of sub-crate paths, I think that's probably what Github was complaining about, but would still like to know where to find the error so I can be sure I got everything right.

I didn't see any errors as well.

On another note, maybe it's best to explicitly list all crates with their respective maintainers instead of relying on the wildcard (e.g. bdk_electrum's maintainers should list leonardo and evan, even though they're on the wildcard expression).

Good point, I've added all the crates explicitly now. Also added one I missed, /crates/file_store/ with @nymius .

I think I also found the error mammal mentioned. It's on the diff and reminded me to give all named maintainers at least write permission.

I agree with the path proposed by #1973. I can take care of examples/ in the meanwhile, but I would remove it once we know for sure examples/ is a subset of bdk-cli functionality.

[luisschwab]

I agree with nymius, the examples can eventually be converted to well written READMEs in their respective crates.

[ValuedMammal]

Yes it was only the write permissions error.
