This reduces chances of errors where consumers of strings mutate inputs and reduces memory usage of the app. Test suite passes now, but there may be some stuff left, so we will run a few sites on a branch prior to merging

# Public: Instances of TopMenuItem should be instantiated from segments contained in SiteSetting.top_menu.
|
|
# Exposes relevant properties and methods that dictate which query methods should be called from the ListController.
|
|
# Segment data should start with a route fragment in one of the following formats:
|
|
# a topic route, such as 'latest' or 'new' (see ListController for valid options)
|
|
# the literal string "categories"
|
|
# a specific category route, must start with 'category/' followed by the route, i.e. 'category/xyz'
|
|
#
|
|
# A topic route can optionally specify a single category to exclude using the '-category' option, i.e. 'new,-xyz'
|
|
#
|
|
# Examples
|
|
#
|
|
# item = TopMenuItem.new('unread')
|
|
# item.name # => "unread"
|
|
#
|
|
# item = TopMenuItem.new('latest,-video')
|
|
# item.name # => "latest"
|
|
# item.has_filter? # => true
|
|
# item.filter # => "video"
|
|
#
|
|
# item = TopMenuItem.new('category/hardware')
|
|
# item.name # => "category"
|
|
# item.has_filter? # => false
|
|
# item.has_specific_category? # => true
