How do I convert a string into hash in Ruby?

I have a file with space separated values:

Paul Smith 12345678
John Alex Doe 23456789
Lucy S Alena Blissett 34567890

And need to convert it to a hash like this:

{"Paul Smith"=>"12345678", "John Alex Doe"=>"23456789", "Lucy S Alena Blissett"=> "34567890"}

I can follow these tips for CSV but am a bit stumped by TSV and new line characters.

Thanks for any help!

Use String#scan and convert resulting array to hash:

File.read('file').scan(/^(.*)\s+([^\s]+)\r?$/).to_h
# => {"Paul Smith"=>"12345678", "John Alex Doe"=>"23456789", "Lucy S Alena Blissett"=>"34567890"}

Assuming that the format is not at all tab-separated value, but is separated by spaces:

s = <<_
Paul Smith 12345678
John Alex Doe 23456789
Lucy S Alena Blissett 34567890
_

s.scan(/(.+) (.+)/).to_h

result:

{
  "Paul Smith"            => "12345678",
  "John Alex Doe"         => "23456789",
  "Lucy S Alena Blissett" => "34567890"
}
