How to parse text by new lines?

I have some text that spans multiple lines, and I want to organize it by each new line. An example text is:

Save $5.00 on Candy with Your Pickup Purchase

Other

when you purchase $15.00 worth of candy. Offer valid only when 
Exp 02/09/2019

I'm looking to put each new line in a different array, but not sure how to differentiate the new lines from each other.

You can use:

> str = <<e
> First Line
> Second line
> 
> 
> Fifth Line
> 
> Seventh Line
> e
# => "First Line\nSecond line\n\n\nFifth Line\n\nSeventh Line\n" 

> str.split("\n")
# => ["First Line", "Second line", "", "", "Fifth Line", "", "Seventh Line"]

It will split the string into an array separated by new line characters.

Each element in array represents text line, empty text line represents empty line.
