Compress Forum Templates & Phrases

Speed up your Forums & Save Bandwidth

Description:

Hi, this is a pretty simple hack that involves compressing the 'compiled' version of your templates, this way it only compresses the part thats to be shown on the forum and not the actual template data you edit.

Background:

Got the idea from Zero Tolerance in buro9's thread:
https://vborg.vbsupport.ru/showthread.php?t=69787

The above hack compresses the page at parse time, while it provides some speed enhancement, on large pages you can actually "negate" the point of using the hack in the first place, because of the overhead in compression.

Thus, the creation of this hack is to provide similiar functionality, but done in the adminCP; and without the overhead of constant compression.

Info:

No Queries. Only query is used when compressing your templates, the rest of the time its just pulling the templates straight out of the database like normal.

Updates:

Version 2.8 - Added Strip Whitespace from Start of JS Line by buro9
Version 2.7 - Option to strip HTML Comments from Compressed Output
Version 2.6 - Removed Phrase Compression altogether, Too Iffy
Version 2.5 - Removed the ASCII \n removal, emails should work now.
Version 2.4 - Had to add editor_jsoptions_size to the Bad Templates array, it also was causing a font selection error.
Version 2.3 - Added Phrase compression support, should help further increase page compression.
Version 2.2 - Slightly Recoded Template compression for faster results.
Version 2.1 - Added php_include templates to bad templates, will not compress these.
Version 2.0 - Recoded Script, added support for certain templates to not compress
Version 1.9 - Re-Added support for InLine Styles.
Version 1.8 - Removed support for InLine Styles, all Style data is left with Linebreaks.
Version 1.7 - Removed support for InLine Javascript, all JavaScript is left with Linebreaks.
Version 1.6 - Fixed Tab problem, tabs are replaced with a single space
Version 1.5 - Removed a part of the SQL.
Version 1.4 - TOTALLY Remade, Works perfect now; Ultimate Compression
Version 1.3 - Adjusted Again
Version 1.2 - Adjusted Stripping regex
Version 1.1 - Added Uncompress Support
Version 1.0 - Release

Install:

Step 1. [ Open admincp/template.php ]
Step 2. [ Go to about line: 1278, or just look for $_REQUEST['do'] == 'edit' ]
Step 3. [ Above Step 2, add the below code ]

How-To Run

1. Install
2. In the admincp left navigation, select "Compress Templates".
3. Repeat Step 2 after each modification of your Templates whenever you decide to change something.
4. If you want to uncompress all Templates, select "Uncompress Templates"
5. IF Any Templates Come Out Weird, add the template Name to the Bad Templates Array and Re-Run the Compress Templates.

Had a nice problem relating to the footer template and the inline javascript.

It compressed to:
<script type="text/javascript"></script>

The problem with that is that // is a line comment, and then there is no line break, so the whole javascript is commented out, and menu's do not get initialised, etc.

The result is that those swishy JavaScript drop down menus break.

You can fix this by updating your footer template to just have:
<script type="text/javascript">vBulletin_init();/script>

In place of the larger block. That does it for me

Aside from that minor problem, this hack is wonderful.

I'm going to go off and search for other places that might be impacted by this though... recommendation: Don't compress JavaScript at all... leave line breaks in.

Buro, did you try the new version? Mutli-Line javascript is left in its standard format short of tabs.

ie. using the updated version, my footer looks like this (Compressed Template):

HTML Code:

<script type="text/javascript">
<!--
 // Main vBulletin Javascript Initialization
 vBulletin_init();
 // Initialize 'Active' Table Cells
 //activecells_init();
//-->
</script></body> </html>
