module Nanoc3::Helpers
# Nanoc3::Helpers::Filtering provides a filter method, which allows parts of
# an item to be filtered.
#
# For example, the following piece of code only runs the "rubypants" filter
# on the second paragraph:
#
# <p>Lorem ipsum dolor sit amet...</p>
# <% filter :rubypants do %>
# <p>Consectetur adipisicing elit...</p>
# <% end %>
#
# This helper has been tested with ERB and Haml.
#
# To activate this helper, +include+ it, like this:
#
# include Nanoc3::Helpers::Filtering
module Filtering
require 'nanoc3/helpers/capturing'
include Nanoc3::Helpers::Capturing
# Filters the content in the given block and outputs it.
def filter(filter_name, arguments={}, &block)
# Capture block
data = capture(&block)
# Find filter
klass = Nanoc3::Filter.named(filter_name)
raise Nanoc3::Errors::UnknownFilter.new(filter_name) if klass.nil?
filter = klass.new(@item_rep.assigns)
# Filter captured data
filtered_data = filter.run(data, arguments)
# Append filtered data to buffer
buffer = eval('_erbout', block.binding)
buffer << filtered_data
end
end
