Construction and destruction

val create : 
  ?dispose:bool ->
  ?nosig:bool ->
  ?mouse:bool ->
  ?bpaste:bool ->
  ?input:Lwt_unix.file_descr ->
  ?output:Lwt_unix.file_descr ->
  unit ->
  t

create ~dispose ~nosig ~mouse ~input ~output () creates a new terminal.

Note ~dispose arranges for the terminal to be disposed of at the end of the Lwt main loop, and not at process exit.

See Notty_unix.Term.create.

val release : t -> unit Lwt.t

Commands

val image : t -> Notty.image -> unit Lwt.t

val refresh : t -> unit Lwt.t

val cursor : t -> (int * int) option -> unit Lwt.t

Events

val events : t -> [ Notty.Unescape.event | `Resize of int * int ] Lwt_stream.t

events t is the stream of incoming events.

Invoking release will terminate this stream.

Events are:

#Unescape.event, an event from the input fd; or
`Resize (cols, rows) whenever the terminal size changes.

Note This stream is unique; for the same t, events t always returns the same stream.

Properties

val size : t -> int * int

val fds : t -> Lwt_unix.file_descr * Lwt_unix.file_descr

Window size change notifications

Creating a terminal will install a SIGWINCH handler. The handler should not be replaced directly. This API allows the user to monitor deliveries of the signal.

See Notty_unix.Term.Winch.

val winch : unit -> unit Lwt.t

winch () is a thread completing after the next SIGWINCH. A single signal delivery will cause the completion of all waiting winch threads.
