External files provides a shortcode [external] which can be used to insert the contents of a file or url into the current post or page. The plugin will automatically format the text based on the extension (for files) or mime type (for urls), using Alex Gorbatchevs’ <a href="http://alexgorbatchev.com" title="More about Syntax Highlighter" rel="nofollow ugc">Syntax Highlighter</a> javascript.
The shortcode can accept three optional parameters:
<ul>
<li>format can be used to specify a highlighting format, rather than letting the plugin decide which format to use</li>
<li>start specifies a line number to output from, so sections of a file/url can be shown</li>
<li>end specifies the line to stop at</li>
</ul>
See the installation page for usage examples.
The available formats are:
<ul>
<li>AS3</li>
<li>Bash</li>
<li>Cpp</li>
<li>CSharp</li>
<li>Css</li>
<li>Delphi</li>
<li>Diff</li>
<li>Groovy</li>
<li>Java</li>
<li>JavaFX</li>
<li>JScript</li>
<li>Perl</li>
<li>Php</li>
<li>Plain</li>
<li>PowerShell</li>
<li>Python</li>
<li>Ruby</li>
<li>Scala</li>
<li>Sql</li>
<li>Vb</li>
<li>Xml</li>
</ul>
<h3>Future features</h3>
Following is a list of ideas and features to add:
<ul>
<li>BASE_PATH and BASE_URL options that can be used in the shortcode to avoid typing the same long path/url each time</li>
<li>a list of available formats with the checkboxes to enable/disable each individually, thus avoiding having to load all of them</li>
<li>an option for changing the theme of the syntax highlighter</li>
</ul>

This small plugin (2 Kb) moves JavaScript to the footer and improve page load times. 
Note: this only works if your other plugins and theme add the JavaScripts correctly.
Configurations are not required! You just have to install it and after the plugin does it all, none further action it’s required.

Speed Up – JavaScript To Footer
