ERB is a most commonly used for rendering HTML in Rails applications, but it can also easily be used to render any text document.
Binding is a rather strange interface to be passing into a method call - since I was rendering templates from within a rake task I really just wanted to pass a hash of values. It turns out ERB recently introduced this functionality in Ruby 2.5, but since I’m not on the latest version I had to find a different solution.
The cleanest solution I could find was to use an OpenStruct. It’s not ideal, but it’s straightforward.
Or just use Ruby 2.5!
