|
|
|
|
<p>The system <var>foo</var> is loaded (and compiled, if necessary)
|
|
by evaluating the following Lisp form:
|
|
</p>
|
|
<div class="example">
|
|
<pre class="example">(asdf:load-system :<var>foo</var>)
|
|
</pre></div>
|
|
|
|
<p>On some implementations (see <a href="Convenience-Functions.html">Convenience Functions</a>),
|
|
ASDF hooks into the <code>cl:require</code> facility and you can just use:
|
|
</p>
|
|
<div class="example">
|
|
<pre class="example">(require :<var>foo</var>)
|
|
</pre></div>
|
|
|
|
<p>Note that the canonical name of a system is a string, in <em>lowercase</em>.
|
|
System names can also be specified as symbols (including keyword
|
|
symbols).
|
|
If a symbol is given as argument, its package is ignored,
|
|
its <code>symbol-name</code> is taken, and converted to lowercase.
|
|
The name must be a suitable value for the <code>:name</code> initarg
|
|
to <code>make-pathname</code> in whatever filesystem the system is to be found.
|
|
</p>
|
|
<p>Using lowercase as canonical is unconventional,
|
|
but was selected after some consideration.
|
|
The type of file systems we support
|
|
either have lowercase as customary case (Unix, Mac, Windows)
|
|
or silently convert lowercase to uppercase (lpns).
|
|
