Module: Cumuliform::DSL::Helpers

Included in:
Template
Defined in:
lib/cumuliform/dsl/helpers.rb

Overview

Contains DSL methods for including modules containing simple helper methods

Helper methods are isolated from the template object, so they can’t call other DSL methods. They’re really intended for wrapping code that is used in several places but requires complex setup, for example a third-party API that issues tokens you need to include in your template in some way.
