Ruby 1.9 compat

Remember when Ruby supported `when :`? Well, it doesn't in 1.9, so let's make sure we use `then`, without ruining our lovely new hash syntax!

Input

#!/usr/bin/env ruby

class Klass
  ITEMS = {
    foo: ["bar", "baz"],
    lorem: "ipsum",
  }

  def initialize(args)
    @item = case args.first
    when :foo, :bar: ITEMS[:foo][1]
    when :lorem    : ITEMS[:lorem]
    end
  end
end

Output

#!/usr/bin/env ruby

class Klass
  ITEMS = {
    foo: ["bar", "baz"],
    lorem: "ipsum",
  }

  def initialize(args)
    @item = case args.first
    when :foo, :bar then ITEMS[:foo][1]
    when :lorem     then ITEMS[:lorem]
    end
  end
end
