def escape_sequence?
  output.is_a?(Vedeu::Models::Escape)
end

#render_output ⇒ Array|String|NilClass

Send the view to the renderers. If the output is a Models::Escape object (typical when showing or hiding the cursor) then we bypass the Terminal::Buffer and write directly to the terminal because escape sequences only make sense to the terminal and not other renderers.

Returns:

  • (Array|String|NilClass)
