My apologies for resurrecting this old thread, but it’s the most specific one I found for my question: Is there a fundamental reason why syncthing doesn’t sync .stignore files? If not, How about adding it as an option?
My use-case is syncing (between work PC and MacBook) a project folder, of which some sub-folders are git repositories. Some of them are individually synced with GitHub. From experience I learned to avoid conflicts between git’s and syncthing’s syncs by adding the sub-folders’ names to both .stignore files. This would be easier if there was a “sync ignore patterns”-option.
