title: Ruby setting ENV variables on a mac
body: <p>I would like to try an keep my development machine as close as the production server (heroku in this case).</p>
  
  <p>Heroku lets you define config vars ie.</p>
  
  <pre><code>config:add key=val
  </code></pre>
  
  <p>This is now pretty secure as secret key values are not stored in my code.</p>
  
  <p>Do you know how and where can I create such environment variables per app on my local mac machine.</p>
  
  <p>I have googled this and as of yet not found a good solution. Any ideas ?</p>
  
  <p>Thanks in advance.</p>
