Base formatting instruction recognized by Format

type t

Immutable document type

type ('a, 'b) fmt = ('a, t, t, 'b) format4

type printer0 = t -> t

type 'a printer = 'a -> printer0

val empty : t

Empty document

val format : Format.formatter -> t -> unit

format ppf doc sends the format instruction of doc to the Format's formatter doc.

val fold : ('acc -> element -> 'acc) -> 'acc -> t -> 'acc

Fold over a document as a sequence of instructions

val msg : ('a, t) fmt -> 'a

msg and kmsg produce a document from a format string and its argument

val kmsg : (t -> 'b) -> ('a, 'b) fmt -> 'a

val printf : ('a, printer0) fmt -> 'a

printf and kprintf produce a printer from a format string and its argument

val kprintf : (t -> 'b) -> ('a, t -> 'b) fmt -> 'a

val open_box : box_type -> int -> printer0

The functions below mirror Format printers, without the pp_print_ prefix naming convention

val close_box : printer0

val text : string printer

val string : string printer

val bytes : bytes printer

val with_size : int printer

val int : int printer

val float : float printer

val char : char printer

val bool : bool printer

val space : printer0

val cut : printer0

val break : spaces:int -> indent:int -> printer0

val custom_break : fits:(string * int * string) as 'a -> breaks:'a -> printer0

val force_newline : printer0

val if_newline : printer0

val flush : printer0

val force_stop : printer0

val open_tbox : printer0

val set_tab : printer0

val tab : printer0

val tab_break : width:int -> offset:int -> printer0

val close_tbox : printer0

val open_tag : stag printer

val close_tag : printer0

val list : ?sep:printer0 -> 'a printer -> 'a list printer

val iter : 
  ?sep:printer0 ->
  iter:(('a -> unit) -> 'b -> unit) ->
  'a printer ->
  'b printer

val array : ?sep:printer0 -> 'a printer -> 'a array printer

val seq : ?sep:printer0 -> 'a printer -> 'a Seq.t printer

val option : ?none:printer0 -> 'a printer -> 'a option printer

val result : ok:'a printer -> error:'e printer -> ('a, 'e) result printer

val either : left:'a printer -> right:'b printer -> ('a, 'b) Either.t printer
