Overview

Utility class for extracting Ruby script from a Slim template that can then be linted with a Ruby linter (i.e. is “legal” Ruby).

The goal is to turn this:

- if items.any?
  table#items
  - for item in items
    tr
      td.name = item.name
      td.price = item.price
- else
   p No items found.

into (something like) this:

if items.any?
  for item in items
    puts item.name
    puts item.price
else
  puts 'No items found'
end

The translation won’t be perfect, and won’t make any real sense, but the relationship between variable declarations/uses and the flow control graph will remain intact.
