Printable.Make
Implement Printable
interface from the minimum implementation.
Takes a module T
, that provides a function pp : t printer
and a module_name
, and implements the rest of the Printable
interface.
module M : sig ... end
val to_string : M.t -> string
to_string x
returns a human-readable representation of x
val str : unit -> M.t -> string
str () t
is formatted output function that matches "%a" conversion format specifier in functions, that prints to string, e.g., sprintf
, failwithf
, errorf
and, surprisingly all Lwt
printing function, including Lwt_io.printf
and logging (or any other function with type ('a,unit,string,...) formatN`. Example:
Or_error.errorf "type %a is not valid for %a"
Type.str ty Exp.str exp
val pps : unit -> M.t -> string
synonym for str
val ppo : Core_kernel.Out_channel.t -> M.t -> unit
will print to a standard output_channel
, useful for using in printf
, fprintf
, etc.
val pp_seq : Stdlib.Format.formatter -> M.t Core_kernel.Sequence.t -> unit
prints a sequence of values of type t
