Is there a way to reuse an argument in fmt.Printf?

I have a situation where I want to use my printf argument twice.

fmt.Printf("%d %d", i, i)

Is there a way to tell fmt.Printf to just reuse the same i?

fmt.Printf("%d %d", i)

You can use the [n] notation to specify explicit argument indexes like so:

fmt.Printf("%[1]d %[1]d\n", i)

Here is a full example you can experiment with: http://play.golang.org/p/Sfaai-XgzN

Another option is text/template:

package main

import (
   "strings"
   "text/template"
)

func format(s string, v interface{}) string {
   t, b := new(template.Template), new(strings.Builder)
   template.Must(t.Parse(s)).Execute(b, v)
   return b.String()
}

func main() {
   i := 999
   println(format("{{.}} {{.}}", i))
}
