File picker: ignore git submodules

[beeb]

The file picker section of the config provides much-useful options to disable showing certain types of hidden or git files in the file picker.

However, I would love to have an option to disable all files located inside any git submodule. Take for instance foundry, which uses git submodules for project libraries/dependencies. When I add e.g. forge-std as a git submodule, which gets cloned into the lib folder, then all the source files for forge-std show up in my file picker.

I couldn't find an easy way to hide those, as obviously I can't git-ignore a git submodule.

Thanks!

You can use a .helix/ignore file in 23.10+

Thanks! Not ideal, as I probably then need to either add this ignore file to .gitignore or publish it to the repo, but it will do.

[beeb]

in fact I will add .helix/ignore to my global gitignore so it's fine!

@beeb you can create and use a global ~/config/helix/ignore file in your Helix config directory as well, see: #9102

Thanks for the hint!

Yeah custom ignore logic like that is hard to add because it's not supported by the ignore crate. I also think while this may be useful in this one generic instance it doesn't seem generally useful (or a common ignore convention). Using .helix/ignore seems more appropriate
