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

$pagesaved_kilobyte=number_format((($pagesaved_byte)/1024),2);
$pagesaved_perc=number_format(((100*$pagesaved_byte)/$page_byte),2);

That's the current contents of the plugin. If I'm understanding it correctly, I shouldn't see things like:

<!-- header Gallery Links-->

When I view my source if the comments are being stripped, correct? One of the main reasons is that I've been writing code for a living for ages now, and I tend to comment the hell out of every change I make. So people viewing my source tend to see some rather interesting comments.

<!-- What the @#@$ did I screw up this time? -->

Because right now, this is my compression "Savings".

[Output: 0.00 Kb. compressed to 82.54 Kb. by saving -82.54 Kb. (0.00%)]

There's a space in the original code snippet I posted, but I put another one in anyhow.

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

Still no love from that, I'm still seeing all of my commented stuff.

(Thank you very much for the help btw, ryuji, I appreciate you takin' the time to help me sort this out. )

This won't move it, but if you at least want to change the look of it, add a CSS to you your MAIN statement for it, something like:

.compressor
{
color: #2886B6;
font: 10px verdana;
}

And then change the span class="smallfont" tag in the plugin itself to span class="compressor".



On a nother note, I'd love it if someone could find a way to make this conditional work. I've tried it in a few places and haven't found something to make it happen.

$output = str_replace('</body>', '<if condition="in_array($bbuserinfo['usergroupid'], array(6))"><center><span class="compressor">[O: ' . $page_kilobyte . ' Kb C:<b>' . $pagenew_kilobyte . '</b> Kb. S: <b>' . $pagesaved_kilobyte . '</b> Kb. (' . $pagesaved_perc . '%)]</span></center></if></body>', $output); 
//Compressor

Running it on 3.5.3 and getting the paragraph break problem on Advanced Edit

i meant in your templates... you can remove all the spaces but on my templates it removed code it wasnt supposed to when i did that, best way is to download the whole style and then use a find and replace to add a space to all of them

[Smiry Kin's]

with 3.5.2

and element skil.

it messes up the DHTML thing.. which is a pain really.. any way to sort this?

[mox-]

Wow, I just installed it and it seems to be working fine.

Is there a way to remove all <!-- comments --> in the code ? This would save a lot too.

[Totti]

mox- read the thread ...
All the last posts are about it

My problem is that i got some
<!--
bloa
bla
blubb
-->
code which is not stripped at all ... any way sorting it out beside making it one line with <!-- xxx --> in code?!?
