Realtime Template Compressor: Reduces page sizes, loads pages faster, saves bandwidth

This is a port of Logican's Realtime Template Compressor hack from vBulletin 2.2.x to vBulletin 3.5.0 Beta 1. I wrote this by rewriting a version of the original hack, that I wrote for my forums when they ran 3.0.x, so that it would function as a plugin for 3.5.0.

I had originally sent this to Logican for him to release it but he replied granting me permission to release it; hence why I'm releasing this.

Installation is very simple. Just import the plugin via vBulletin's "Download / Upload Plugins" page in the Plugin System in the Admin Control Panel and you're done.

I'll try to correct any bugs that you might find. Let me know if you like this plugin and don't forget to click the install link if you install this.

Update History

Version 1.1.0: The expression was replaced with a more efficient one that increases the compression level from approximately 1-2% to approximately 4-8%.
Version 1.0.0: Initial Release

Two screen shots to confirm no issue with advanced editor or spacing issues with post titles.

I have tested this on 3.5.3, before the plugin, in titles adding 10 extra spaces in between two words on a new post title, the extra spacing was stripped away by default.

This addon is not the cause as far as i can tell.

Added Note:
Want to thank ShiningArcanine & Logican for their work, great mod and good savings for the site.

these are the results of my experiments with the code... this one doesnt break anything and ill see if i can figure out a way to make it not bust javascript

PHP Code:

//Logician Hack:
//$page_byte=strlen($output);

//this broke scripts on my setup, if you want to test, click on 'more' smileys in advanced editor or try to bring up the user popup when you click on there name on a thread
                //$output=preg_replace ('/(\s*)\r\n(\s*)/', "", $output);
//this broke scripts on my setup, if you want to test, click on 'more' smileys in advanced editor or try to bring up the user popup when you click on there name on a thread


$output=preg_replace ('/\r\n(\s*)/', "\r\n", $output);
$output=preg_replace ('/<!-- .*? -->/',"",$output);


//$pagenew_byte=strlen($output);
//$page_kilobyte=number_format(($page_byte/1024),2);
//$pagenew_kilobyte=number_format(($pagenew_byte/1024),2);
//$pagesaved_byte=$page_byte-$pagenew_byte;
//$pagesaved_kilobyte=number_format((($pagesaved_byte)/1024),2);
//$pagesaved_perc=number_format(((100*$pagesaved_byte)/$page_byte),2);

//$output = str_replace('</body>', '<center><span class="smallfont">[Output: ' . $page_kilobyte . ' Kb. compressed to <b>' . $pagenew_kilobyte . '</b> Kb. by saving <b>' . $pagesaved_kilobyte . '</b> Kb. (' . $pagesaved_perc . '%)]</span></center></body>', $output);
//Logician Hack:

Works good, but kills javascript roll overs in my headers. :disappointed:

The solution to the paragraph bug is to alter the regular expression in such a way that newline characters appearing between textarea tags are left untouched.

I leave this as an exercise for the reader.

Any reader in there?

Installed with 3.5.0 and my button rollovers are working fine.

CMPS: [Output: 67.15 Kb. CMP 64.81 Kb. Net 2.35 Kb. (3.50%)]

Stripping the comments works really, really well. No bugs at all in 3.5.3 with plenty of mods. One thing I wouldn't mind seeing added is something that keeps a running tally of the total compressed kB savings. It'd be great to know at the end of the month just how much this is saving me. Also being able to only display this to admins would be ultimate. I'd strip the output code altogther, but I'm way too much of a dork to go without it.

Solid mod. Thanks much.
