    \$\begingroup\$ Some minor syntax changes: ARGV → $*; each_char → chars; do..end → {..}; printf → $><< + % would lead to this: "qwertyuiop↵asdfghjkl↵zxcvbnm".split($*[0])[1].chars{|i|$><<"%s "%i}. More in Tips for golfing in Ruby. \$\endgroup\$ Commented Nov 24, 2015 at 16:09

    \$\begingroup\$ I see you didn't got the hint in my first comment. In Ruby there is no need for triple quotes around multiline strings. (Actually I had no idea until now that it accepted by Ruby.) \$\endgroup\$ Commented Nov 24, 2015 at 16:21

    \$\begingroup\$ The leading spaces in the output are quite ugly. As . in regular expression does not match \n by default, better use that for the spacing: puts"qwertyuiop↵asdfghjkl↵zxcvbnm ".split($*[0])[1].gsub(/./,'\& '). Though the code length will remain the same. \$\endgroup\$ Commented Nov 24, 2015 at 16:38
