tail

Overview ¶

Package tail mimicks the behaviour of `tail -f`

tail watches an events file for writes and sends out matching events, one for each line written. It is careful to parse the data read in a separate goroutine, which helps assure all events are caught.

ev, _ := tail.WatchEvents(ctx, path.Dir(dir), path.Base(dir))
for event := range ev {
	fmt.Println(ev.Service, ev.Name)
	switch ev.EventType {
	case tail.FeedEvent:
		// [...]
	case tail.DocEvent:
		// [...]
	case tail.NotifyEvent:
		// [...]
	case tail.NoneEvent:
		// [...]
	}
}
