OK well the original was dangerous and unfair. I'm a big fan of case-gets-when-regexp structures though so...
puts "Yes means No and No means Yes. Delete all files [Y]?"
yes, no = "no", "yes"
default = no
def delete_all_files
# exec("rm -rf *")
puts "deleted all of your files!"
end
delete_all_files if "yes" == case gets
when /y.*/i
yes
when /n.*/i
no
else
default
end

How about creating a real CLI for it. You'll have to forgive me.. I'm quite new to Ruby and have come from a C environment, which is influenced in my coding. However, the following code actually works and it's quite easy to understand.
class Zomg
def ask()
printf("Yes means No, and No means Yes. Delete all files? [Y]\n");
takeAns();
end
def takeAns()
printf("> ");
ans=gets.strip.downcase.split("");
procAns(ans);
end
def procAns(ans)
if (ans[0] == nil)
printf("You entered nothing so I will default..\n");
delete_all_files();
elsif (ans[0] == "y")
printf("Okay, I won't delete anything\n");
Process.exit;
elsif (ans[0] == "n")
printf("You selected no, so everything will be deleted\n");
delete_all_files();
else
printf("Wtf? Would you mind trying that again??\n");
printf("Press enter to start again..\n");
gets;
ask();
end
end
def delete_all_files()
#too afraid to run this - exec("rm -rf *");
printf("*** Removed all of your shit. Have a nice day\n");
gets; # wait for key stroke then close
Process.exit;
end
end
s = Zomg.new;
s.ask();
Optimize for poeticness.
