Navigating Phoenix's or Elixir's Codebase in Vim using cTags
<p>This is my setup:</p>

<pre><code>Mac OS          10.12.1
ViM             8.0.52
Exuberant Ctags 5.8
</code></pre>

<p>My <code>.vimrc</code> has: <code>set tags=tags</code></p>

<p>I generate the tags file using <code>ctags -R .</code> within the project root directory and it generated a file called <code>tags</code> in that same folder.</p>

<p>The ctags navigation within my own project files work just fine. But whenever I try to see the source code for the Phoenix Framework itself (or its dependencies) I get a </p>

<pre><code>E426: Tag not found: Mix
</code></pre>

<p>How do I fix this and navigate Phoenix's source code? </p>
