Returns a specification to start this module under a supervisor.

See Supervisor.

Closes the window by stopping the GenServer. Prior to this, termbox is de-initialized so that the terminal is restored to its previous state.

Fetches an attribute for the window. This is currently limited to the window dimensions, which can be useful when laying out content.

Examples

iex> Window.fetch(:height)
{:ok, 124}
iex> Window.fetch(:width)
{:ok, 50}
iex> Window.fetch(:foo)
{:error, :unknown_attribute}

Starts the gen_server representing the window.

The window is intended to be run as a singleton gen_server process, as initializing the underlying termbox library multiple times on the same TTY can lead to undefined behavior.

Options

• :name - Override the name passed to GenServer.start_link/3. By

               default, `name: Ratatouille.Window` is passed in order to
               protect against accidental double initialization, but this
               can be overridden by passing `nil` or an alternate value.

• :input_mode - Configure the input mode. See Ratatouille.Constants.input_mode/1

               for possible values.

• :output_mode - Configure the output mode. See Ratatouille.Constants.output_mode/1

               for possible values.

Updates the window by rendering the given view to the termbox buffer and presenting it.
