title: Enabling autocomplete in sbcl
body: <p>I have recently started to learn lisp, and have mainly bin using clisp and vim. I wanted to try sbcl as well, since this is often recommended as one of the best, free lisp compilers. There is one thing, though, which makes sbcl more difficult to use for me: I can not get autocomplete in the REPL, which I do have in clisp. That is, when I start sbcl and type the following (as an example),</p>
  
  <pre><code>* (requi&lt;tab&gt;
  </code></pre>
  
  <p>where <code>&lt;tab&gt;</code> is the literal tab character, I do not get a list of completions, but rather a verbose tab character. In clisp, <code>&lt;tab&gt;</code> will complete the previous line to <code>* (require</code>.</p>
  
  <p>As I am fairly new to lisp, the autocomplete functionality in clisp is really handy, so it would really be very convenient if anyone could explain how to get it in sbcl as well.</p>
