val silent : 'a printer

Prints nothing.

val unit : unit printer

Prints "()".

val int : int printer
val string : string printer
val bool : bool printer
val float3 : float printer
val float : float printer
val exn : exn printer

Printer using Printexc.to_string.

since
3.0
val space : unit printer

Alias to pp_print_space.

since
3.2
val cut : unit printer

Alias to pp_print_cut.

since
3.2
val break : (int * int) printer

Tuple-ized printer form of pp_print_break.

since
3.2
val newline : unit printer

Force newline (see Format.pp_force_newline).

since
1.2
val substring : (string * int * int) printer

substring (s,i,len) prints the substring (s,i,len), where i is the offset in s and len the number of bytes in the substring.

raises Invalid_argument

if the triple (s,i,len) does not describe a proper substring.

since
1.2
val text : string printer

Print string, but replacing spaces with breaks and newlines with newline. See pp_print_text on recent versions of OCaml.

since
1.2
val char : char printer
since
0.14
val int32 : int32 printer
since
0.14
val int64 : int64 printer

val flush : unit printer

Alias to Format.pp_print_flush.

since

val string_quoted : string printer

Similar to CCString.print.

since
0.14
val list : ?⁠sep:unit printer -> 'a printer -> 'a list printer
val array : ?⁠sep:unit printer -> 'a printer -> 'a array printer
val arrayi : ?⁠sep:unit printer -> (int * 'a) printer -> 'a array printer
val seq : ?⁠sep:unit printer -> 'a printer -> 'a Stdlib.Seq.t printer
val iter : ?⁠sep:unit printer -> 'a printer -> 'a iter printer
val opt : 'a printer -> 'a option printer

opt pp prints options as follows:

  • Some x will become "some foo" if pp x ---> "foo".
  • None will become "none".
val pair : ?⁠sep:unit printer -> 'a printer -> 'b printer -> ('a * 'b) printer
val triple : ?⁠sep:unit printer -> 'a printer -> 'b printer -> 'c printer -> ('a * 'b * 'c) printer
val quad : ?⁠sep:unit printer -> 'a printer -> 'b printer -> 'c printer -> 'd printer -> ('a * 'b * 'c * 'd) printer
val append : unit printer -> unit printer -> unit printer

append ppa ppb first prints ppa (), then prints ppb ().

since
3.2
val append_l : unit printer list -> unit printer

append_l pps runs the printers in pps sequentially.

since
3.2
val within : string -> string -> 'a printer -> 'a printer

within a b p wraps p inside the strings a and b. Convenient, for instances, for brackets, parenthesis, quotes, etc.

since
0.17
val map : ('a -> 'b) -> 'b printer -> 'a printer
val vbox : ?⁠i:int -> 'a printer -> 'a printer

Wrap the printer in a vertical box.

parameter i

level of indentation within the box (default 0).

since
0.16
val hvbox : ?⁠i:int -> 'a printer -> 'a printer

Wrap the printer in a horizontal/vertical box.

parameter i

level of indentation within the box (default 0).

since
0.16
val hovbox : ?⁠i:int -> 'a printer -> 'a printer

Wrap the printer in a horizontal or vertical box.

parameter i

level of indentation within the box (default 0).

since
0.16
val hbox : 'a printer -> 'a printer

Wrap the printer in an horizontal box.

since
0.16
val return : ('a, _, _, 'a) Stdlib.format4 -> unit printer

return "some_format_string" takes a argument-less format string and returns a printer actionable by (). Examples:

  • return ",@ "
  • return "@{<Red>and then@}@,"
  • return "@[<v>a@ b@]"
since
1.0
val of_to_string : ('a -> string) -> 'a printer

of_to_string f converts its input to a string using f, then prints the string.

since
1.0
val const : 'a printer -> 'a -> unit printer

const pp x is a unit printer that uses pp on x.

since
1.0
val some : 'a printer -> 'a option printer

some pp will print options as follows:

  • Some x is printed using pp on x
  • None is not printed at all
since
1.0
val lazy_force : 'a printer -> 'a lazy_t printer

lazy_force pp out x forces x and prints the result with pp.

since
2.0
val lazy_or : ?⁠default:unit printer -> 'a printer -> 'a lazy_t printer

lazy_or ?default pp out x prints default if x is not evaluated yet, or uses pp otherwise.

since
2.0

ANSI codes

Use ANSI escape codes https://en.wikipedia.org/wiki/ANSI_escape_code to put some colors on the terminal.

This uses tags in format strings to specify the style. Current styles are the following:

  • "reset" resets style
  • "black"
  • "red"
  • "green"
  • "yellow"
  • "blue"
  • "magenta"
  • "cyan"
  • "white"
  • "bold" bold font
  • "Black" bold black
  • "Red" bold red
  • "Green" bold green
  • "Yellow" bold yellow
  • "Blue" bold blue
  • "Magenta" bold magenta
  • "Cyan" bold cyan
  • "White" bold white

if the triple (s,i,len) does not describe a proper substring.

val text : string printer
Print string, but replacing spaces with breaks and newlines with newline. See pp_print_text on recent versions of OCaml.
since
1.2
val string_lines : string printer
string_lines out s prints s with all newlines ('\n') replaced by a cut, in a vertical box. It does NOT insert breakable spaces in place of spaces, unlike text. This means an already formatted string can be displayed inside another formatter without mangling the indentation.

ANSI codes
Use ANSI escape codes https://en.wikipedia.org/wiki/ANSI_escape_code to put some colors on the terminal.
This uses tags in format strings to specify the style. Current styles are the following:
  • "reset" resets style
  • "black"
  • "red"
  • "green"
  • "yellow"
  • "blue"
  • "magenta"
  • "cyan"
  • "white"
  • "bold" bold font
  • "Black" bold black
  • "Red" bold red
  • "Green" bold green
  • "Yellow" bold yellow
  • "Blue" bold blue
  • "Magenta" bold magenta
  • "Cyan" bold cyan
  • "White" bold white
Example:
set_color_default true;;
 
 Format.printf
   "what is your @{<White>favorite color@}? @{<blue>blue@}! No, @{<red>red@}! Ahhhhhhh@.";;
