Manages the console
The console is a system than can report messages and a status to the user. It is usually the terminal the application is connected to, however it could be something else. This module allow to set a global backend for the application as well as composing backends.
module Backend : sig ... endThe main backend for the application
include Backend.Sval print_user_message : User_message.t -> unitFormat and print a user message to the console
val set_status_line : User_message.Style.t Pp.t option -> unitChange the status line
val print_if_no_status_line : User_message.Style.t Pp.t -> unitPrint a message if the backend does not display the status line. This is needed so that the important status changes show up even when a dumb terminal backend is used.
val print : User_message.Style.t Pp.t list -> unitprint paragraphs is a short-hand for:
print_user_message (User_message.make paragraphs) val printf : ('a, unit, string, unit) format4 -> 'aprintf fmt is a convenient function for debugging. It formats a string and then print it raw followed by a newline. It is the same as:
print [Pp.verbatim (sprintf fmt ...)] For properly formatted output you should use print.
module Status_line : sig ... endStatus line management
