Question

for fun I am creating in ruby a simple leet (1337) generator

so i am doing something like this, which works but doesn’t look very efficient, i am sure it can be accomplished with one line only…

    def leet
       words = words.gsub(/a/, '4')
       words = words.gsub(/e/, '3')
       words = words.gsub(/i/, '1')
       words = words.gsub(/o/, '0')
       words = words.gsub(/s/, '5')
       words = words.gsub(/t/, '7')
       puts words
    end

Can you give me a help here? 🙂 thanks!

Answer 1

def leet(word)
  puts word.gsub(/[aeiost]/,'a'=>'4','e'=>'3','i'=>'1','o'=>'0','s'=>'5','t'=>'7')
end
