Desktop: File exclusion per directory

[DBLouis]

I would like to be able to exclude files to be sync by directory. I know it can be done globally but a per directory exclusion list (like a .gitignore) would be great.

The context is that I am using cmake and I would like to exclude build files but keep sources being synced.

I would really like this, mostly because I wouldn't have to manage separate exlusion lists on every client I use

This would be an awesome feature, enabling me to keep programming projects in sync with minimal configuration.
I suggest we read .gitignore and exclude everything in there by default. This should cover most use cases. I don't think anyone would have a problem with ignored files not being synced (correct me if i'm wrong).

I'd be willing to implement this, shouldn't be too hard. Some file searching tools such as https://github.com/BurntSushi/ripgrep and https://github.com/ggreer/the_silver_searcher do this by default.
We could even ask git if some file is ignored, see https://git-scm.com/docs/git-check-ignore. Do you think it's ok to introduce a dependency to git for this?

Try to create .sync-exclude.lst in any directory and then after the sync remove this file.
Client will state "Could not read system exclude file" and will never sync again. Client restart helps.
