How do I default to time.Now() for time flags

[midnightexigent]

In general, is there a way to provide a path to a function whose call that returns the default value ?

[alecthomas]

I would use a variable for this:

var cli struct {
  Now time.Time `default:"${now}"`
}

kong.Parse(cli, kong.Vars{"now": time.Now().String()})

(off the top of my head - may need some tweaking to actually work)
