</pre></div>

<p>The live-reload module enables Sly programs to react to changes in the
file system and reload assets automatically, which is useful when
using external programs such as an image editor or map editor.  This
makes it easy to see the changes made to game assets quickly.

<dl>
<dt><a name="index-live_002dreload"></a>Function: <strong>live-reload</strong> <em><var>proc</var> [<var>polling-interval</var>]</em></dt>
<dd><p>Return a new procedure that re-applies <code>proc</code> whenever the
associated file is modified.  The new procedure returns a signal
(see <a href="Signals.html#Signals">Signals</a>) that contains the return value of <code>proc</code>.  The
first argument to <code>proc</code> must be a file name string.
</p>
<p>A simple polling method is used to test for updates.  Files are polled
every <code>polling-interval</code> ticks (120 by default).
