(** Additional functions. *)

val input_lines : in_channel -> string Enum.t

(** Returns an enumeration over lines of an input channel, as read by the

 [input_line] function. *)

val input_chars : in_channel -> char Enum.t

(** Returns an enumeration over characters of an input channel. *)

val input_list : in_channel -> string list

(** Returns the list of lines read from an input channel. *)

val input_all : in_channel -> string

(** Return the whole contents of an input channel as a single

 string. *)

val print_bool : bool -> unit

(** Print a boolean to stdout. *)

val prerr_bool : bool -> unit

(** Print a boolean to stderr. *)

val input_file : ?bin:bool -> string -> string

(** returns the data of a given filename. *)

val output_file : filename:string -> text:string -> unit

(** creates a filename, write text into it and close it. *)

val string_of_char : char -> string

(** creates a string from a char. *)

external identity : 'a -> 'a = "%identity"

(** the identity function. *)

val unique : unit -> int

(** returns an unique identifier every time it is called. *)

val dump : 'a -> string

(** represent a runtime value as a string. Since types are lost at compile

  time, the representation might not match your type. For example, None

  will be printed 0 since they share the same runtime representation. *)

val print : 'a -> unit

(** print the representation of a runtime value on stdout.

  See remarks for [dump]. *)

val finally : (unit -> unit) -> ('a -> 'b) -> 'a -> 'b 

(** [finally fend f x] calls [f x] and then [fend()] even if [f x] raised

  an exception. *)
