Rules

# frozen_string_literal: true

#!/usr/bin/env ruby

# The Rules file contains the processing instructions for all items in a Nanoc site.
# Three different kinds of rules exist:
# http://nanoc.ws/doc/rules/
# http://nanoc.ws/doc/identifiers-and-patterns/
#
# compilation rules
#      These rules describe the actions that should be executed during compilation
#      (filtering, layouting, and snapshotting).
# routing rules
#     These rules describe the path where the compiled items should be written to.
# layouting rules
#     These rules describe the filter that should be used for a given layout.
#
# For every item, Nanoc finds the first matching compilation rule. Similarly, for every layout, Nanoc finds the first
# matching layouting rule. The first matching rule that is found in the rules file is used.
#
# If an item or a layout is not using the correct rule, double-check to make sure that the rules
# are in the correct order.
