tilt-rails_erb adds supports ERB templates using Rails’ 5.1 Erubi-based ERB handler, which is different than standard ERB in that it supports using <%= foo do %><% end %> syntax and it auto-escapes output.

gem install tilt-rails_erb

require 'tilt/rails_erb'

The use case for tilt-rails_erb is in middleware in a Rails app that wants to share template files with the Rails app. Rails uses a non-standard ERB processor, and supports syntax that standard ERB doesn’t support. If you use that syntax in your Rails templates and want to share the templates with a middleware that uses tilt for renderning, you should use this library.

Note that this library makes the the Tilt::RailsERBTemplate the default Tilt .erb template handler, which can cause problems if you also use non-Rails ERB templates in the same application.
