This is just string interpolation.

• asicsp 6y ago
  %q allows different delimiters to represent single quoted strings, which doesn't have string interpolation. For ex: $ ruby -e 'a=5; puts "[#{a}]"' [5] $ ruby -e 'a=5; puts %q/[#{a}]/' [#{a}]

    %Q or just % does interpolation: $ ruby -e 'a=5; puts %Q/[#{a}]/' [5] $ ruby -e 'a=5; puts %/[#{a}]/' [5]
