val hash_string : string -> int

val hash_list : ('a -> int) -> 'a list -> int

val hash2 : int -> int -> int

val hash3 : int -> int -> int -> int

Printing helpers

val pp_opt : 
  ?none:string ->
  (Buffer.t -> 'a -> unit) ->
  Buffer.t ->
  'a option ->
  unit

Print an option

val pp_list : 
  pp_sep:(Buffer.t -> 'a -> unit) ->
  sep:'a ->
  pp:(Buffer.t -> 'b -> unit) ->
  Buffer.t ->
  'b list ->
  unit

Print a list with separator into a buffer

val print_opt : 
  ?none:string ->
  (Format.formatter -> 'a -> unit) ->
  Format.formatter ->
  'a option ->
  unit

Print an option.

val print_list : 
  print_sep:(Format.formatter -> 'a -> unit) ->
  sep:'a ->
  print:(Format.formatter -> 'b -> unit) ->
  Format.formatter ->
  'b list ->
  unit

Print a list with separator into a buffer

Lexbuf helpers

val filename_of_input : 
  [ `Stdin | `File of string | `Contents of string * string ] ->
  string

Filename string of an input.

val filename_of_input_source : 
  [ `Stdin | `File of string | `Raw of string * string ] ->
  string

Filename string of an input source.

val mk_lexbuf : 
  [ `Stdin | `File of string | `Contents of string * string ] ->
  Lexing.lexbuf * (unit -> unit)

Returns the lexbuf associetd with the given file or stdin, with the correct filename, together with a function to close the associated file descriptor. The `Contents constructor expect first a name for the input stream (to report errors), and then a string with the actual contents to be parsed.
