IntrohiveTemplatingLanguage
ITL is a template language built on Introhive Expression Language (IEL.) It is a similar style to "handlebars" and other formats that use curly-braces to switch between static and dynamic content.
This solves the problem of having configurable outputs built from a controlled set of inputs that the developer defines. This could be for generating HTML or other things like configuring an API endpoint in a setting. If used appropriately it can help with the goal of "configurability everywhere" in the system.
The template functionality is very simple but powerful as you have the full capabilities of IEL as your disposal. Additionally macros to enhance the readability of the templates are supported to generate the messier IEL expressions dynamically.
Installation
Add this line to your application's Gemfile:
gem 'introhive_templating_language'
