Helpers

Helpers are Ruby modules that get mixed into the template evaluation context. Typically they add methods you may invoke from within templates to produce additional output, retrieve objects or data, or perform other actions.

To add a helper, simply use the helper keyword in your pipeline configuration _ext/pipeline.rb, and specify the module to add as a helper. Be sure you require the appropriate files to have the module loaded.

Awestruct::Extensions::Pipeline.new do
  helper Awestruct::Extensions::IntenseDebate
  helper Awestruct::Extensions::GoogleAnalytics
end

Write your own helper

By default, the _ext/ directory is added to the load path, so you may simply add your helper definition there.

Helper Definition

_ext/my_helper.rb

module MyHelper
  def right_now
    Time.now
  end
end

Pipeline Configuration

_ext/pipeline.rb

require 'my_helper'
