title: How to set environment variables in fish shell
body: <p>Can someone please tell me what's the correct way to set a bunch of environment variables in the fish shell?</p>
  <p>In my <code>~/.config/fish/config.fish</code> file, I have a function to setup my environment variables like so:</p>
  <pre><code>function setTESTENV
        set -x BROKER_IP '10.14.16.216'
        set -x USERNAME 'foo'
        set -x USERPASS 'bar'
  end 
  </code></pre>
  <p>When I type from the command prompt <code>setTESTENV</code> and do a <code>env</code> in the command line, I don't see this information.</p>
