Module: Nanoc2::Helpers::Filtering

Defined in:
lib/nanoc2/helpers/filtering.rb

Overview

Nanoc2::Helpers::Filtering provides a filter method, which allows parts of a page 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 likely only works with ERB (and perhaps Erubis).

To activate this helper, include it, like this:

include Nanoc2::Helpers::Filtering
