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

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

val pure : 'a -> 'a t
pure x is return x.
val mguard : bool -> unit t
mguard c is pure () if c is true, [] otherwise. This is useful to define a list by comprehension, e.g.:
# let square_even xs =
       let* x = xs in
       let* () = mguard (x mod 2 = 0) in
       return @@ x * x;;
