Input

$cons->Input

• Reads an event from the input buffer. Returns a list of values, determined by the type of event. A keyboard event will contain the following values, in order:
  • Event type (1 for keyboard)
  • Key state - true if the key is being pressed, false if the key is being released
  • Repeat count - the number of times the key is being held down
  • Virtual keycode of the key
  • Virtual scancode of the key
  • ASCII code of the character (if the key is a character key, 0 otherwise)
  • State of the control keys (SHIFTs, CTRLs, ALTs, etc.)

  A mouse event will return the following values, in order:

  • Event type (2 for mouse)
  • X coordinate (column) of the mouse location
  • Y coordinate (row) of the mouse location
  • Button state - the mouse button(s) which are pressed
  • State of the control keys (SHIFTs, CTRLs, ALTs, etc.)
  • Event flags for the type of the mouse event

  This method will return undef on error.

  Note that the events returned depend on the input mode of the console; for example, mouse events are not intercepted unless ENABLE_MOUSE_INPUT is specified.
