Pp (qcheck-multicoretests-util.Util.Pp)

type 'a t = bool -> Stdlib.Format.formatter -> 'a -> unit

The type of pretty-printers to valid OCaml syntax. The bool argument asks the printer to wrap its output inside parentheses if it produces a non-atomic expression.

val to_show : 'a t -> 'a -> string

to_show pp converts a pretty-printer to a simple 'a -> string function that generate everything on one line. If the environment variable MCTUTILS_TRUNCATE is set to a length, it will truncate the resulting string if it exceeds that length.

val of_show : ('a -> string) -> 'a t

of_show show uses a simple 'a -> string function as a pretty-printer. Unfortunately, it will wrap the resulting string with parentheses in more cases than strictly necessary.

val cst0 : string -> Stdlib.Format.formatter -> unit

val cst1 : 'a t -> string -> bool -> Stdlib.Format.formatter -> 'a -> unit

cst1 pp name par v fmt pretty-prints a constructor name with one parameter, using pp to pretty-print its argument v, wrapping itself into parentheses when par.

  'b t ->
  string ->
  bool ->
  Stdlib.Format.formatter ->
  'a ->
  'b ->
  unit

cst2 pp1 pp2 name par v1 v2 fmt pretty-prints a constructor name with two parameters, using ppi to pretty-print its argument vi, wrapping itself into parentheses when par.

val cst3 : 
  'a t ->
  'b t ->
  'c t ->
  string ->
  bool ->
  Stdlib.Format.formatter ->
  'a ->
  'b ->
  'c ->
  unit

cst3 pp1 pp2 pp3 name par v1 v2 v3 fmt pretty-prints a constructor name with three parameters, using ppi to pretty-print its argument vi, wrapping itself into parentheses when par.

pp_result pp_ok pp_error pretty-prints a value of type ('o, 'e) result using pp_ok to pretty-print values of type 'o and pp_error for values of type 'e.
