width padding not working with SprintFunc

[pszxzsd]

e.g.:

cyan := color.New(color.FgCyan).SprintFunc()
fmt.Printf("%-5v%v\n", cyan("foo"), "bar")

should print "foo bar" (with 2 spaces) but prints "foobar"

That is not because of a problem with SprintFunc, but because cyan("foo") returns a string with 5 bytes. Or put differently: fmt.Printf does not take the color codes into account when formatting the string.

I suggest using SprintfFunc to format the string before the color codes are added:

cyan := color.New(color.FgCyan).SprintfFunc()
fmt.Println(cyan("%-5v", "foo") + "bar")

Thanks @mgeisler for the clarification. Closing as this is the indented way. There is not much we can do. @pszxzsd I recommend to use it like @mgeisler recommended. Thanks.
