# Navigation link helper
#
# Returns an `li` element with an 'active' class if the supplied
# controller(s) and/or action(s) are currently active. The content of the
# element is the value passed to the block.
#
# options - The options hash used to determine if the element is "active" (default: {})
# :controller - One or more controller names to check, use path notation when namespaced (optional).
# :action - One or more action names to check (optional).
# :path - A shorthand path, such as 'dashboard#index', to check (optional).
# :html_options - Extra options to be passed to the list element (optional).
# block - An optional block that will become the contents of the returned
# `li` element.
#
# When both :controller and :action are specified, BOTH must match in order
# to be marked as active. When only one is given, either can match.
#
# Examples
#
# # Assuming we're on TreeController#show
#
# # Controller matches, but action doesn't
# nav_link(controller: [:tree, :refs], action: :edit) { "Hello" }
# # => '<li>Hello</li>'
#
# # Controller matches
# nav_link(controller: [:tree, :refs]) { "Hello" }
# # => '<li class="active">Hello</li>'
#
# # Several paths
# nav_link(path: ['tree#show', 'profile#show']) { "Hello" }
# # => '<li class="active">Hello</li>'
#
# # Shorthand path
# nav_link(path: 'tree#show') { "Hello" }
# # => '<li class="active">Hello</li>'
#
# # Supplying custom options for the list element
# nav_link(controller: :tree, html_options: {class: 'home'}) { "Hello" }
# # => '<li class="home active">Hello</li>'
#
# # For namespaced controllers like Admin::AppearancesController#show
#
# # Controller and namespace matches
# nav_link(controller: 'admin/appearances') { "Hello" }
# # => '<li class="active">Hello</li>'
#
# # Controller and namespace matches but action doesn't
# nav_link(controller: 'admin/appearances', action: :edit) { "Hello" }
# # => '<li>Hello</li>'
#
# # Shorthand path with namespace
# nav_link(path: 'admin/appearances#show') { "Hello"}
# # => '<li class="active">Hello</li>'
#
# # When `TreeController#index` is requested
# # => '<li>Hello</li>'
#
# # Paths, controller and actions can be used at the same time
# nav_link(path: 'tree#show', controller: 'admin/appearances') { "Hello" }
#
# nav_link(path: 'foo#bar', controller: 'tree') { "Hello" }
# nav_link(path: 'foo#bar', controller: 'tree', action: 'show') { "Hello" }
# nav_link(path: 'foo#bar', action: 'show') { "Hello" }
