title: How do I, line by line, turn a csv into an array using Ruby?
body: <p>input file looks like:</p>
  
  <pre>
  dog,white,male
  cat,purple,female
  rat,gray,male
  </pre>
  
  <p>and i want to go through and do things with that data, line by line.</p>
  
  <pre><code>File.open("animals.csv")
    while file has next line
      currentline = array with each cell being an entry in the array
      if currentline[0] == dog
        put "dogs are cool"
      end
      put "your animal is a " + currentline[0]
    end
  </code></pre>
  
  <p>You get the idea, right? I want to manipulate data line with ifs and whatnot and print it all out at the end.</p>
  
  <p>Thanks</p>
