Overview ¶
Package es contains an emergency stop implementation. This data is read from es.json file every 10 seconds. If the data changes, subscribers will receive an update.
Using this is simple:
ch, cancel := es.Data.Subscribe("SatelliteDiskErase")
defer cancel()
if <-ch != es.Go {
// Do something
}
select {
case <-ch:
log.Println("ES changed to Stop state ")
}

func (*Reader) Subscribe ¶
Subscribe returns a channel that sends a Status whenever a ES entry changes status. This will send the initial Status immediately. If the name is not found, this will send Stop and close the channel. If there is a transition to Stop, the channel will be closed once this is sent. Once you either receive a Stop or are no longer interested in listening, simply call Cancel().
