<a id="sec:altmoduleapi"></a>

<p>The <a id="idx:usemodule1:1460"></a><a class="pred" href="import.html#use_module/1">use_module/1</a> 
predicate from <a class="sec" href="import.html">section 5.3</a> defines 
import and export relations based on the filename from which a module is 
loaded. If modules are created differently, such as by asserting 
predicates into a new module as described in <a class="sec" href="dynamic-modules.html">section 
5.12</a>, this interface cannot be used. The interface below provides 
for import/export from modules that are not created using a module file.

<dl class="latex">
<dt class="pubdef"><a id="export/1"><strong>export</strong>(<var>+PredicateIndicator, 
...</var>)</a></dt>
<dd class="defbody">
Add predicates to the public list of the context module. This implies 
the predicate will be imported into another module if this module is 
imported with <a id="idx:usemodule12:1461"></a><span class="pred-ext">use_module/[1,2]</span>. 
Note that predicates are normally exported using the directive <a id="idx:module2:1462"></a><a class="pred" href="defmodule.html#module/2">module/2</a>. <a id="idx:export1:1463"></a><a class="pred" href="altmoduleapi.html#export/1">export/1</a> 
is meant to handle export from dynamically created modules.</dd>
<dt class="pubdef"><a id="import/1"><strong>import</strong>(<var>+PredicateIndicator, 
...</var>)</a></dt>
<dd class="defbody">
Import predicates <var>PredicateIndicator</var> into the current context 
module. <var>PredicateIndicator</var> must specify the source module 
using the &lt;<var>module</var>&gt;:&lt;<var>pi</var>&gt; construct. 
Note that predicates are normally imported using one of the directives <a id="idx:usemodule12:1464"></a><span class="pred-ext">use_module/[1,2]</span>. 
The <a id="idx:import1:1465"></a><a class="pred" href="altmoduleapi.html#import/1">import/1</a> 
alternative is meant for handling imports into dynamically created 
modules. See also <a id="idx:export1:1466"></a><a class="pred" href="altmoduleapi.html#export/1">export/1</a> 
and <a id="idx:exportlist2:1467"></a><span class="pred-ext">export_list/2</span>.
