class Roda
module RodaPlugins
# The path plugin adds support for named paths. Using the +path+ class method, you can
# easily create <tt>*_path</tt> instance methods for each named path. Those instance
# methods can then be called if you need to get the path for a form action, link,
# redirect, or anything else. Example:
#
# plugin :path
# path :foo, '/foo'
# path :bar do |bar|
# "/bar/#{bar.id}"
# end
#
# route do |r|
# r.post 'bar' do
# bar = Bar.create(r.params['bar'])
# r.redirect bar_path(bar)
# end
# end
