Type definitions and core functions

type box_type =
  1. | H
  2. | V
  3. | HV
  4. | HoV
  5. | B

Format box types

type stag = Format.stag
type element =
  1. | Text of string
  2. | With_size of int
  3. | Open_box of {
    1. kind : box_type;
    2. indent : int;
    }
  4. | Close_box
  5. | Open_tag of Format.stag
  6. | Close_tag
  7. | Open_tbox
  8. | Tab_break of {
    1. width : int;
    2. offset : int;
    }
  9. | Set_tab
  10. | Close_tbox
  11. | Simple_break of {
    1. spaces : int;
    2. indent : int;
    }
  12. | Break of {
    1. fits : (string * int * string) as 'a;
    2. breaks : 'a;
    }
  13. | Flush of {
    1. newline : bool;
    }
  14. | Newline
  15. | If_newline
  16. | Deprecated of Format.formatter -> unit
    (*

    Escape hatch: a Format printer used to provide backward-compatibility for user-defined printer (from the #install_printer toplevel directive for instance).

    *)

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 with_size : int printer

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 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
