<h2><code>logtalk_load/2</code></h2>

|
|
|
|
|
<h4>Description</h4>
|
|
|
|
<blockquote>
|
|
<pre>logtalk_load(Entity, Options)
|
|
logtalk_load(Entities, Options)</pre>
|
|
<p>
|
|
Compiles to disk and then loads to memory an entity or a list of entities (objects, protocols or categories) using a list of options. The Logtalk file name extension (by default, <code>.lgt</code>) should be omitted. Note that the first argument is a list of entity/file names, not file paths. In other words, the files must exist in your current working directory.
|
|
</p>
|
|
<p>
|
|
For a description of the available compiler options, please <a href="../../userman/installing.html#options">consult</a> the User Manual.
|
|
</p>
|
|
<p>
|
|
Note that only the errors related to problems in the predicate arguments are listed below. Other exceptions may be thrown by the compiler if any of the loaded entities contain errors.
|
|
