#

The library's input-processing abstraction. Platform-specific implementations must implement an Input and provide it to mkVtyFromPair.

Constructors

  • Input
    • eventChannel :: TChan InternalEvent

      A channel of events generated by input processing. The input implementation must write its input events to this channel; the Vty event loop will read from this channel and provide the events to the user's application via nextEvent.

    • shutdownInput :: IO ()

      Shut down the input processing. As part of shutting down the input, this should also restore the input state if appropriate.

    • restoreInputState :: IO ()

      Restore the terminal's input state to what it was prior to configuring the input for Vty. This should be done as part of shutdownInput but is exposed in case it needs to be used directly.

    • inputLogMsg :: String -> IO ()

      Log the specified message.
