The worst 3 line I've ever written, that also works.

badness.rb

s = options[:sudo].nil? ? sudo? || dependency.sudo? : options[:sudo]
f = options[:flags].nil? ? "#{flags+' ' if flags}#{dependency.flags}" : options[:flags]
system "#{'sudo ' if s}#{program} #{command} #{f+' ' unless f.to_s == ''}#{dependency}"

Try this:

s = options[:sudo] || sudo? || dependency.sudo?
f = options[:flags] || "#{flags+' ' if flags}#{dependency.flags}"

That is not equivalent. Imagine this case:

options[:sudo] = false
sudo? = true
dependency.sudo? = true

You would say s == true but it shouldn't. I want options[:sudo] to have a higher precedence then anything else.

Keep in mind false.nil? == false
