#layout(lay) ⇒ Object

Sets a layout to be used by a particular controller.

Example:

class MyAwesomeController
  include Mack::Controller

  # Sets all actions to use: "#{Mack.root}/app/views/layouts/dark.html.erb" as they're layout.
  layout :dark

  def index
    # Sets this action to use: "#{Mack.root}/app/views/layouts/bright.html.erb" as it's layout.
    render(:text, "Welcome...", :layout => :bright)
  end

  def index
    # This will no use a layout.
    render(:text, "Welcome...", :layout => false)
  end
end

The default layout is “#/app/views/layouts/application.<format>.erb”.
