Called when a directory or file is renamed TODO: fsnotify behavior after rename is obscure if we have foo dir with a bar file inside and we are watching foo dir, on renaming foo to boo we will get rename event for foo dir but if we delete boo/bar we will get remove event for foo/bar not boo/bar

type Watcher

type Watcher struct {
	sync.Mutex
	// contains filtered or unexported fields

Wrapper around fsnotify watcher to suit lime needs

• Watching directories, we will have less individual watchers
• Have multiple subscribers on single file or directory
• Watching a path which doesn't exist yet
• Watching and applying action on certain events
