Formatters for inspecting OCaml values.

Formatters of this module dump OCaml value with little control over the representation but with good default box structures and, whenever possible, using OCaml syntax.

Polymorphic type formatters

val pair : 'a t -> 'b t -> ('a * 'b) t

pair pp_fst pp_snd formats an OCaml pair using pp_fst and pp_snd for the first and second projection.

val option : 'a t -> 'a option t

option pp_v formats an OCaml option using pp_v for the Some case. No parentheses are added.

val list : 'a t -> 'a list t

list pp_v formats an OCaml list using pp_v for the list elements.

val array : 'a t -> 'a array t

array pp_v formats an OCaml array using pp_v for the array elements.

val hashtbl : 'a t -> 'b t -> ('a, 'b) Hashtbl.t t

hashtbl pp_k pp_v formats an unspecified representation of the bindings of a hash table using pp_k for the keys and pp_v for the values. If the hash table has multiple bindings for a given key, all bindings are formatted, with the most recent binding first.

val queue : 'a t -> 'a Queue.t t

queue pp_v formats an unspecified representation of an OCaml queue using pp_v to format its elements, in least recently added order.

val stack : 'a t -> 'a Stack.t t

stack pp_v formats an unspecified representation of an OCaml stack using pp_v to format its elements in top to bottom order.

val iter : (('a -> unit) -> 'b -> unit) -> 'b t -> 'a t -> 'b t

iter iter pp_name pp_elt formats an unspecified representation of the iterations of iter over a value using pp_elt. The iteration is named by pp_name.

val iter_bindings : 
  (('a -> 'b -> unit) -> 'c -> unit) ->
  'c t ->
  'a t ->
  'b t ->
  'c t

iter_bindings ~sep iter pp_name pp_k pp_v formats an unspecified representation of the iterations of iter over a value using pp_k and pp_v. The iteration is named by pp_name.
