Defined in:

Overview

Custom ERB compiler which causes variable interpolation inside <%= %> to be json encoded. Inside regular <% %>, the variables are used without json encoding.

CloudFormation stack options defaults can be set directly within a template by setting @stack_options. See README.md “CloudFormation stack options” for details.

Basic validation functionality is possible by setting @validations. See README.md “Validations” for details
