16 3 This question is similar to a LOT of questions, but in no such way is it anything of a duplicate. This question is about string concatenation and writing better code less than it is for checking nil/zero. Currently I have: file.puts "cn: " + (var1.nil? ? "UNKNOWN" : var1) Which works fine, but doesn't look good. What is a better way to write this in ruby so that I am checking for nil and not concatenating it ruby code-formatting share | improve this question edited Jan 14 '15 at 2:44 JakeGould 20.6k 8 46 74
