Looking at Hugo's dependencies, the copy on my machine (possibly outdated) uses this library: https://github.com/howeyc/fsnotify https://github.com/howeyc/fsnotify However, there's a moving notice on that page for this repo: https://github.com/go-fsnotify/fsnotify https://github.com/go-fsnotify/fsnotify Fsnotify will probably make it into the standard library or other core golang repository at some point, given that it could help speed up the compiler. However there's nothing particularly mystical about it that prevents a 3rd party library from being just as good.
