Too many levels of symbolic links

[adrianlzt]

I have a directory with many markdown files used to take notes. In that directory structure there are symbolic links doing circular paths. For example:
/home/adrian/adrianRepo/web/apps/google/programacion -> ../../../programacion/google
/home/adrian/adrianRepo/programacion/google/apps -> /home/adrian/adrianRepo/web/apps/google

This seems to configure marksman returning this error:

I'm not sure how this could be fixed, but I think circular symbolic links could be normal.

Thanks!

Thanks for reporting this @adrianlzt! I understand the problem. Not sure what's the best way to solve it though. Need to think for a bit.

(some vague concerns around uniqueness of paths to documents and also resolving symlinks to folders outside of the root folder; maybe reading workspace folder in a BFS fashion and picking the shortest paths could be enough...)

[adrianlzt]

Maybe just ignoring symlinks? Or an option to ignore them.

Also hitting this on the fwupd repo. I didn't look at the impl too closely but the Rust walkdir crate has some logic to do cycle detection by tracking the parent dirs. Maybe that's useful 🙂 https://github.com/BurntSushi/walkdir/blob/2.5.0/src/lib.rs#L973

Thanks for this nice LSP! :)
