ubuntu remind me in ten minutes

ubuntu remind me in ten minutes ###background

Very useful voice commands for cortana on windows phone: wake me up in ten minutes. Remind me to do XXX in an hour.

 ### ideas

Speech recognition under ubuntu is difficult to do, so I had to do something on the command line to remind me of such a thing after a few minutes.

What to do in a few minutes is easy to program. golang's time.after_func is fine. Then the bell rang. I didn't understand how the beep command was used, but I found the espeak command again.

espeak is a text-to-speech program, commonly known as TTS.

sudo apt-get install espeak
espeak "it's time to get up"

###golang code is as follows:

package main
import (
	"flag"
	"os/exec"
	"time"
)
var n_secs int
var n_mins int
var n_hours int
var words string
func init() {
	flag.IntVar(&n_secs, "s", 0, "remind me after n seonds")
	flag.IntVar(&n_mins, "m", 0, "remind me after n minutes")
	flag.IntVar(&n_hours, "h", 0, "remind me after n hours")
	flag.StringVar(&words, "w", "ling ling ling", "the words to speak when time is up")
}
func main() {
	var c = make(chan int)
	var d time.Duration = 0
	flag.Parse()
	switch {
	case n_secs != 0:
		d += time.Duration(n_secs) * time.Second
	case n_mins != 0:
		d += time.Duration(n_mins) * time.Minute
	case n_hours != 0:
		d += time.Duration(n_hours) * time.Hour
	}
	time.AfterFunc(d, func() {
		exec.Command("espeak", words).Run()
		c <- 1
	})
	<-c
}

###usage:

remindme -m 5
remindme -m 30 -w "homework homework"
remindme -h 1 -m 30 -w "clean the room, clean the room"
