About the screenshot

Liquid is a template engine which was crafted for very specific requirements

• It has to have simple markup and beautiful results. Template engines which don’t produce good looking results are no fun to use.
• It needs to be non-evaling and secure. Liquid templates are made so that users can edit them. You don’t want to run code on your server which your users wrote.
• It has to be stateless. The compile and render steps have to be separate, so that the expensive parsing and compiling can be done once; later on, you can just render it by passing in a hash with local variables and objects.
• It needs to be able to style emails as well as HTML.
