Ports

KeyIn

KeyIn(*, supress_input: bool = False)

Bases: Input

Keyboard input port. Produces KeyMsg objects.

Parameters:

• supress_input (bool, default: False ) –

  Prevent the input events from being passed to the rest of the system

is_enabled

is_enabled: bool

True if port is listening and generating messages

calls

calls: list[None | tuple[tuple, dict], list[SubscribedCall]]

Message match arguments and callables that will be called with matching incoming messages. None conditions matches any message.

pressed_keys

pressed_keys: list[Key] = []

Currently pressed keys

subscribe

subscribe(
    type: None | Container[KeyEvent] | KeyEvent = None,
    shortcut: None | Container[str] | str = None,
) -> Callable

Decorator to subscribe a callable to the input's messages.

Decorator without arguments subscribes a callable to all the input's messages.

Decorator with arguments subscribes a callable to the input's messages that match conditions set by arguments. It works the same way as message's matches method:

1. If condition is None or omitted it matches anything.

2. If condition equals attribute it matches the attribute.

3. If condition is a container and contains the attribute it matches the attribute.

Examples

1. Calls function for all MIDI port's messages:

   @midi_input_instance.subscribe
   def function(msg: MidiMsg) -> None:
       pass
   

2. Calls function for OSC messages from specific address:

   @osc_input_instance.subscribe(address='/live/song/get/track_data')
   def function(msg: OscMsg) -> None:
       pass
   

3. Call object instance method for MIDI port's "note on" and "note off" messages:

   midi_input_instance.subscribe((MidiType.NOTE_ON, MidiType.NOTE_OFF))(object.method)
   

Returns:

• Callable –

  Subscribed callable.

KeyOut

KeyOut()

Bases: Output

Keyboard output port. Sends KeyMsg objects.

is_enabled

is_enabled: bool

True if port is ready to send messages

send

send(msg: KeyMsg) -> None

Send the keyboard input.

Parameters:

• msg (KeyMsg) –

  object to send
