class Roda
module RodaPlugins
# 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.
module EmptyRoot
module RequestMethods
# Match when the remaining path is the empty string,
# in addition to the default behavior of matching when
# the remaining path is +/+.
