# The category chunk looks for "category: news" on a line by
# itself and parses the terms after the ':' as categories.
# Other classes can search for Category chunks within
# rendered content to find out what categories this page
# should be in.
#
# Category lines can be hidden using ':category: news', for example
class Category < Chunk::Abstract
  def self.pattern() return /^(:)?category\s*:(.*)$/i end

  end

  # Mark this chunk's start and end points but allow the terms
  # after the ':' to be marked up.
  def mask(content) pre_mask + list.join(', ') + post_mask end

  # If the chunk is hidden, erase the mask and return this chunk
  # otherwise, surround it with a 'div' block.
