What does this kind of keyword use do in Ruby?

I'm new to Ruby, and learning Ruby on Rails.

I saw this code:

class DemoController < ApplicationController
  layout false

  def index
  end
end

What does layout false mean?

I've seen the include keyword, but I've never seen layout before. Is a Rails specific keyword?

What exactly does the 'keyword space keyword' form mean in Ruby, and is there a language specification? And can I create my own 'keywords'?

layout false means that render will be without any layouts.

layout isn't a keyword. layout false is the same as layout(false). The parentheses are optional for method calls in Ruby.

See the layout documentation for details of the layout() method in Rails.

The view in ruby on rails applications takes the layout defined in layouts/application.html.erb by default. In case you want to use any different layout for specific views, you can change the layout parameter. Here the

views under Demo controller will not use the default layout

. You can also use layout parameters while rendering templates/view files. These are pre-defined keywords and in case you are looking for own set of keywords. You have to override these, but it's not a best practice considering ruby's "convention over configuration". For details can check Rails layout guides
