class Roda
module RodaPlugins
# The multi_route plugin allows for multiple named routes, which the
# main route block can dispatch to by name at any point. If the named
# route doesn't handle the request, execution will continue, and if the
# named route does handle the request, the response by the named route
# will be returned.
#
# Example:
#
# plugin :multi_route
#
# route(:foo) do |r|
# r.is 'bar' do
# '/foo/bar'
# end
# end
#
# route(:bar) do |r|
# r.is 'foo' do
# '/bar/foo'
# end
# end
#
# route do |r|
# r.on "foo" do
# route :foo
# end
#
# r.on "bar" do
# route :bar
# end
# end
#
# Note that in multi-threaded code, you should not attempt to add a
# named route after accepting requests.
module MultiRoute
# Initialize storage for the named routes.
def self.configure(app)
app.instance_exec{@named_routes ||= {}}
end
module ClassMethods
# Copy the named routes into the subclass when inheriting.
def inherited(subclass)
super
subclass.instance_variable_set(:@named_routes, @named_routes.dup)
end
# Return the named route with the given name.
def named_route(name)
@named_routes[name]
end
# If the given route has a named, treat it as a named route and
# store the route block. Otherwise, this is the main route, so
# call super.
def route(name=nil, &block)
if name
@named_routes[name] = block
else
super(&block)
end
end
end
module InstanceMethods
# Dispatch to the named route with the given name.
def route(name)
instance_exec(request, &self.class.named_route(name))
end
end
