deleting blank lines after loop

Question

ok, I have the following, very simple code:

f = \"String1\\n\\n\\nString2\\n\\n\\n\"
f.each_line do |t|
  t.delete! \"\\n\"
  puts t.inspect
end

Answer 1

You could split the string by \n, and then reject any blank lines:

f = "String1\n\n\nString2\n\n\n"
f.split("\n").reject { |i| i.empty? }
#=> ["String1", "String2"]

You'd end up with an Array that you can output as you'd like.
