Easier API for page minification

[GoogleCodeExporter]

I've studies the Minify builder a little, but couldn't make much of the way 
the html is minified.

A nice way would be the following, where Minify would follow the config.
<?php ob_start(); ?>
<!-- html -->

<?
$contents = 0b_get_contents();
ob_end_clean();
require '/min/Minify.php';
Minify::serve('Page', $contents);
// This as a cleaner alternative to 
http://code.google.com/p/minify/source/browse/trunk/min/builder/index.php

Notice this is an enhancement, couldn't figure out how to change it.

Just a note:

$contents = 0b_get_contents();
ob_end_clean();

is the same as 

$contents = ob_get_clean();

Even better:
<?php ob_start(); ?>
<!-- html -->

<?
require '/min/Minify.php';
Minify::serve('Page', $ob_end_clean(););

How about:

<?php require $_SERVER['DOCUMENT_ROOT'] . '/min/page.php'; ?>
<!-- html -->

page.php could include all needed Minify files and ob_start('ob_minify_page'). 
ob_minify_page() would receive the buffer, check get_included_files() for 
mtimes, 
and return Minify::serve().

This is how http://www.mnot.net/cgi_buffer/ works. It won't work for everyone, 
but I 
like it.

• Changed state: Accepted
• Added labels: Priority-High, Type-Enhancement
• Removed labels: Priority-Medium, Type-Defect

[GoogleCodeExporter]

Does that mean it will be cgi_buffer but better?

Or will this result in an overal compression suite, where you can do something 
like:

Even tought of an complete api, will denote it here when I have it ready.

It would do everything Minify does for JS/CSS files, but for HTML. So, full 
minification of markup and script/style contents, gzip, cache headers, and 
conditional GET.

I don't want to rewrite href/src to use Minify or automatically inline content. 
Those decisions should stay with the page author.

The only initial limitation is that it wouldn't notice the modification of 
files 
pulled in using readfile(), since those don't show up in get_included_files(), 
but 
most people don't use readfile for templating anyway.

For the case you may want to make it a more generic suit:

Oh, and forgot to say it, it won't replace the current functionality, but 
should be 
nice.

R350 has this working. Just copy the two files in /min/, and at the top of your 
file:
require $_SERVER['DOCUMENT_ROOT'] . '/min/pageBuffer.php';

A different API could prevent the page code from being executed at all when the 
cache was fresh (You'd set a server-side maxAge). This would only require that 
another file be appended:

require $_SERVER['DOCUMENT_ROOT'] . '/min/pageCache_pre.php'; 
/* PHP Page here. Not executed if Minify's cache fresh. */
require $_SERVER['DOCUMENT_ROOT'] . '/min/pageCache_post.php';

Noticed a issue, it generates line endings on every first space after the tag 
title.
Example:

<div id="header"></div>
Becomes:
<div
id="header"></div>
And:
<img src="foo.jpg" />
Becomes:
<img
src="foo.jpg" />

This is done to limit line lengths (which I've been told can cause problems in 
some 
apps) and doesn't add any weight ("\n" = 1 byte).

This doesn't work anymore with the recent minify (files changed), how to get 
this behavior back?

Are you using /min/pageBuffer.php? Do you get an error? Checked PHP's error log?

It simply wasn't in the latest download. But I just realized it is in the 
online repo. 
Gonna try that first.
