# ppx_format
Simple syntax for string formatters. This extension features a syntax for string formatting inspired by Python. While processing the source code, each occurence of `"..." % (a, b, c)` is converted into `Printf.sprintf "..." a b c`.
**Examples**:
```ocaml
(* Format with one argument. *)
let () =
let name = Unix.getenv "USER" in
print_endline ("Hello, %s!" % name)
(* Format with multiple arguments. *)
let () =
let name = Unix.getenv "USER" in
let time = Unix.time () in
let cdir = Unix.getenv "PWD" in
print_endline ("Hello %s! Current UNIX time is %f. Your current directory is %s" % (name, time, cdir))
(* Partially applied format. *)
let () =
let hello = (%) "Hello, %s!" in
print_endline (hello "world")
```
