|
|
|
|
<p>The recommended way to load ASDF is via:
|
|
</p><div class="example lisp">
|
|
<pre class="lisp">(require "asdf")
|
|
</pre></div>
|
|
|
|
<p>All actively maintained Lisp implementations now include a copy of ASDF 3
|
|
that you can load this way using Common Lisp’s <code>require</code> function.<a id="DOCF1" href="Loading-a-pre_002dinstalled-ASDF.html#FOOT1"><sup>1</sup></a>
|
|
</p>
|
|
<p>If the implementation you are using doesn’t provide a recent ASDF 3,
|
|
we recommend you upgrade it.
|
|
If for some reason you would rather not upgrade it,
|
|
we recommend you replace your implementation’s ASDF.
|
|
See <a href="Replacing-your-implementation_0027s-ASDF.html">Replacing your implementation’s ASDF</a>.
|
|
If all else fails, see see <a href="Loading-ASDF-from-source.html">Loading ASDF from source</a> below.
|
|
</p>
|
|
<p>If you use an actively maintained implementation that fails to provide
|
|
an up-to-date enough stable release of ASDF,
|
|
you may also send a bug report to your Lisp vendor and complain about it
|
|
— or you may fix the issue yourself if it’s free software.
|
|
</p>
|
|
<p>As of the writing of this manual,
|
|
the following implementations provide ASDF 3 this way:
|
|
ABCL, Allegro CL, CLASP, Clozure CL, CMUCL, ECL, GNU CLISP, LispWorks, MKCL, SBCL.
|
|
The following implementations only provide ASDF 2:
|
|
MOCL, XCL.
|
|
The following implementations don’t provide ASDF:
|
|
Corman CL, GCL, Genera, MCL, SCL.
|
|
The latter implementations are not actively maintained (except maybe GCL);
|
|
if some of them are ever released again, they probably will include ASDF 3.
|
|
</p>
|
|
<p>For maximum convenience you might want to have ASDF loaded
|
|
whenever you start your Lisp implementation,
|
|
for example by loading it from the startup script or dumping a custom core
|
|
— check your Lisp implementation’s manual for details.
|
|
SLIME notably sports a <code>slime-asdf</code> contrib that makes life easier with ASDF.

|
|
<p>NB: all implementations except GNU CLISP also accept
|
|
<code>(require "ASDF")</code>, <code>(require 'asdf)</code> and <code>(require :asdf)</code>.
|
|
For portability’s sake, you should use <code>(require "asdf")</code>.
