splitting a string separated by CRLF into array

[dominique.plante]

How can I get the array

["hello", "world", "123"]

from the string

"hello\r\nworld\r\n123"

Thanks!
Dominique

Thanks! (I like your book BTW - I like how it touches on main, Kernel
stuff, etc...)

I was trying "hello\r\n\world".split('\r\n') and it returned
["hello\r\nworld"]

irb(main):001:0> "hello\r\nworld\r\n123".split
=> ["hello", "world", "123"]

irb(main):011:0> "hello\r\nworld\r\n123".split(/\s+/)
=> ["hello", "world", "123"]

irb(main):012:0> "hello\r\nworld\r\n123".scan(/\S+/)
=> ["hello", "world", "123"]

irb(main):004:0> "hello\r\nworld\r\n123".to_a.map{|x|x.chomp}
=> ["hello", "world", "123"]

irb(main):009:0> "hello\r\nworld\r\n123".inject([]){|a,b| a << b.chomp}
=> ["hello", "world", "123"]

You need to use a double quoted string in order for those escaped
characters to be interpereted as such.
