#start ⇒ Object

Starts the application!

  • A new terminal screen is opened (or rather the current terminal is requested into either :raw or :cooked mode).

  • The cursor visibility is then set dependent on this mode. In :raw mode, the cursor is hidden.

  • The ‘:initialize` event is triggered. Vedeu does not handle this event; the client application may treat this event as Vedeu signalling that it is now ready.

  • We enter into the main sequence where the application will either run once or continuous, interactively or standalone.
