About Developer · **Released**: 08-28-2003

As you know all vbulletin pages consists of templates and templates consists of HTML (+sometimes javascript) tags.

Nearly in all sites and HTML pages, HTML tags are written in a readable format so that developer can read the source code easily. VB templates abide by this rule too.

However when this "nicely readable" code is called by a visitor, page size unnecessarily increases because of the redundant "spaces" and "line breaks" in the source code which have no useful purpose regarding the page output but is there just for making the source code more readable to the developer.

This hack removes these unnecessary spaces and line breaks from your vbulletin templates AT THE MOMENT they are displayed (in realtime). It does NOT touch your original source code so it is still readable to you when you want to edit it in your admin CP. But it compress the output when they are sent to user's browser.

Removal of these unnecessary characters makes sure:
a) Page output shrinks in all vb pages
b) Thus page loads faster by all visitors
c) You save bandwidth.

Since the removed characters are unnecessary characters, display of your page does NOT change. Please see FAQ below for more info.

This hack is 100% compatible with Teck's Microstat Hack and my Advanced Templates: Dynamic Templates Changing according to different conditions hack and WebTemplates 2.x: VB Integrated Content Management System . It is a very easy to install add (just a few lines in 1 step) yet effective.

I appreciate if you can click INSTALL button, if you use the hack. Thank you. :glasses:

I'm not able to track/debug it because I have never experienced such a problem in the boards I have installed the hack. The only display problem I witnessed and reported in the FAQ is the page split links getting closer to eachother.

Yeah, I tried doing this but couldn't figure it out.

I added this to a project I'm currently working on ... and I think it's great.

I modified the expression ...
$vartext = preg_replace ("'([\r\t\n])[\s]+'", "", $vartext);

this has been tested only on a non-public vb3 forum

it seems to compress more then the original (view attachment) and it doesn't remove the "space" between the ....

Thanks for sharing the info. I haven't tested it yet but from the apperance it looks like it can be the cure for guys who are having visual problems. So after I tested it, I plan to add it to the hack code and make it user selectable inside the code so that everybody can select the compression method as they like.

But I'm confused how come it compresses more than my line as your line seems to remove successive spaces and my line removes them all. BTW it is also weird the original source sizes are different in your each screenshots (as if they belong to different pages?)..

Princeton · #95 10-20-2003, 01:43 PM

Currently, I have the compression as selectable by admin (in case of high server load).

I admit most of the compression is done in the <head> CSS section.

(I'm using vb3.)

hmm ... I have to re-check.

I must have minimized a block ... new screenshots attached.

I dont like the way this shrinks the page numbers in the thread list I.E. 1234 instead of 1 2 3 4

*** Installed ***

Thanks reloaded the first page and already see how much was saved, Thanks. Simple yet very very effective.

Excellent! This fixed the spacing, plus increased compression. Thanks, princeton!

To implement this on your site you should remove all comments found within javascripts embedded in your templates. If you do not remove ... you will receive errors in pages with javascript embedded. For example, wywsiwyg editor will not function as it should.

To do this go into your ADMIN PANEL and do a search and replace for
Search for text:
<script type="text/javascript">

</script>
Replace with:
</script>

You can also do this for <style> but it is not necessary as <style> will work when compressed.

If you think the comments are necessary think again ...
Comments are used to hide code from version 1 and 2 browsers. How many users do you think will visit your site with a 1 or 2 browser? And, if so, the site will not work as it should because they will not be able to interpret the javascript.

A condtional statement checking for browser version should be used to render or not render javascript. Why send javascript bytes that will not be utilized by browser?

Broke too much of my spacing, and I don't have enough time to redo it all right now. Awesome idea though, I had a 3.6% save.

Maybe I'll give this other compression method a try one day.

Logician · #**101** 12-31-2003, 08:56 AM

Unfortunately the compression method of princeton creates problems in javascripts as he mentioned above. I confirmed that it compress better and fixes spacing problem but I believe trying to fix all javascripts in all templates is an headache so I prefer to use my compression method. Your call which one you want to use but make sure you fix your javascripts in princeton's method otherwise some features of your board (eg. smilies) will stop.

Frankly speaking I don't see spacing as a problem. It neither interferes with how board functions (it is just visual) nor hard to fix. I dont know how it will do if you have skins or something but in a default vb, it just affects page numbers which is very easy to fix with a one template edit.

Princeton · #**102** 12-31-2003, 03:01 PM

In vB3, you have more control of Search and Replace.
It's only a headache if you don't know how to use it properly. (It takes some time to get use to it.)

In vB3, you'll find that it has a lot of javascript/comments and "empty" space (found in rendered html source) caused by conditionals. Remove all these space/lines/comments and your site will load quicker and save on bandwidth.

- every little bit counts

I am giving this hack a chance, I really am, by hunting all templates in my test forum that contain visible white space and grumpily replacing them with   ... just incorporating the hack isn't enough if you like your page to not look amateurish with all the lost white space...

Even the slightest misalignment makes me cringe, what more for squished links

It seems to me that there is a pretty simple way to deal with this spacing issue. In the preg_replace statement, instead of eliminating all white-space characters between html tags, replace all white-space characters between html tags with one space. The addition to the file size would be minimal and this would deal with the spacing problem. This is what I did on my site and it is working great.

Thanks for a very helpful hack. My site is using 80 - 90% of two T-1's and a 5% or 6% reduction is bandwidth is meaningful. Eric
