module Roda::RodaPlugins::EmptyRoot

  1. lib/roda/plugins/empty_root.rb

The empty_root plugin makes r.root match both on / and on the empty string. This is mostly useful when using multiple rack applications, where the initial PATH_INFO has been moved to SCRIPT_NAME. For example, if you have the following applications:

class App1 < Roda
  on "albums" do
    run App2
  end
end

class App2 < Roda
  plugin :empty_root

  route do |r|
    r.root do
      "root"
    end
  end
end

Then requests for both /albums/ and /albums will return “root”. Without this plugin loaded into App2, only requests for /albums/ will return “root”, since by default, r.root matches only when the current PATH_INFO is / and not when it is empty.
