ruby single word pig latin with regex -

-

calling forth ruby regex masters!

i trying solve problem in ruby using regex. input single word. 2 conditions apply:

  • if starts vowels [aeiou], returns word + 'way'. example, pig_latin('aye') #=> 'ayeway'
  • if starts consonants, moves first letter of word end of string, + 'ay'. pig_latin('map') #=> 'apmay'

i have tried:

def pig_latin(ay)     ay.gsub(/\a[aeiou](w+)/, '\2\1way') end  pig_latin('map') #=> 'map' pig_latin('aye') #=> 'aye'

when tried 

ay.gsub(/^[aeiou](\w+)*/, '\2\1way') pig_latin('map') #=> 'map' pig_latin('aye') #=> 'yeway'

getting close. @ least recognizes consonants - removes 'a' in 'aye'.

i have tried reading regex doc, on gsub , rubular helps illuminate bit, still in dark ages.

in case 2 gsub calls allowed: 

def pig_latin(ay)     ay[0] =~ /[aeiou]/ ? ay.gsub(/([aeiou])(\w+)*/, '\1\2way') : ay.gsub(/([^aeiou])(\w+)*/, '\2\1ay') end  pig_latin("aye") #=> ayeway pig_latin("map") #=> apmay

in case 2 gsub calls not allowed:

def pig_latin(ay)     ay += ( (ay[0] =~ /[aeiou]/).nil? ? "" : "w")     ay.gsub(/([^aeiou]?)([aeiou])(\w+)(.?)/, '\2\3\1\4ay') end  pig_latin("aye") #=> ayeway pig_latin("map") #=> apmay
