Re: [Caml-list] Is it possible to define a Printf.sprintf-like that is lazy?

[Gabriel Scherer <gabriel.scherer@gmail.com>]

let delayed_sprintf fmt = Printf.sprintf (fmt ^^ "%s");;

# let result = Printf.sprintf "%d) %s\n" 3 "foo";;
val result : string = "3) foo\n"

# let thunk = delayed_sprintf "%d) %s\n" 3 "foo";;
val thunk : string -> string = <fun>
# thunk "";;
- : string = "3) foo\n"
