end

#render_output ⇒ Array<String>|String|NilClass

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

Returns:

  • (Array<String>|String|NilClass)
