Joomla: anyone use geshibot? mine's got issues

[Lodius2000]

so first things first, it doesnt highlight this is my example script

<pre xml:php> (<-this works for fomatting but not highlighting but ive also tried <pre lang:php>, <pre lang=php>, then i switched to {geshibot} and tried {geshibot}, {geshibot xml:php}, {geshibot lang:php}, {geshibot lang=php}

<?php

print "hello world";
?>
</pre>

 

also, with both the geshibot and the preloaded geishi mambots it seems like the code is being interpreted as well as displayed, for instance

 

print "<br />\n";

prints

print "
\n";

 

also the code does not wrap so long lines of code break the page layout, how do I get it to put the gray box around the code like we have here on this forum so that it doesnt break the page?

 

any help you guys have is much appreciated
