title: Enable Vim syntax highlighting regardless of filename extension
body: <p>I am opening a file with no extension with <code>vim</code>, say:</p>
  
  <pre><code>myappsetting.conf
  </code></pre>
  
  <p>This file is actually a <code>*.ini</code> file, with following formats:</p>
  
  <pre><code>[setting_a]
  yo = 1234
  </code></pre>
  
  <p>How can I enable <code>vim</code> to correctly display this file with colour with the correct format?</p>
  
  <p>I am looking for some <code>vim</code> command like:</p>
  
  <pre><code>:set syntaxtype=ini
  </code></pre>
  
  <p>Thanks.</p>
