The files in this directory represent the default Minify setup designed to
ease
integration with your site. This app will combine and minify your
Javascript or
CSS files and serve them with HTTP compression and cache
headers.


RECOMMENDED

It's recommended to edit config.php to set
$min_cachePath to a writeable
(by PHP) directory on your system. This will
improve performance.


GETTING STARTED

The quickest way to get started is
to use the Minify URI Builder application
on your website:
http://example.com/min/builder/


MINIFYING A SINGLE FILE

Let's say you
want to serve this file:
 
http://example.com/wp-content/themes/default/default.css

Here's the
"Minify URL" for this file:
 
http://example.com/min/?f=wp-content/themes/default/default.css

In other
words, the "f" argument is set to the file path from root without
the 
initial "/". As CSS files may contain relative URIs, Minify
will automatically
"fix" these by rewriting them as root
relative.


COMBINING MULTIPLE FILES IN ONE DOWNLOAD

Separate the paths
given to "f" with commas.

Let's say you have CSS files at these
URLs:
  http://example.com/scripts/jquery-1.2.6.js
 
http://example.com/scripts/site.js

You can combine these files through
Minify by requesting this URL:
 
http://example.com/min/?f=scripts/jquery-1.2.6.js,scripts/site.js


SIMPLIFYING
URLS WITH A BASE PATH

If you're combining files that share the same
ancestor directory, you can use
the "b" argument to set the base
directory for the "f" argument. Do not include
the leading or
trailing "/" characters.

E.g., the following URLs will serve the
exact same content:
 
http://example.com/min/?f=scripts/jquery-1.2.6.js,scripts/site.js,scripts/home.js

 http://example.com/min/?b=scripts&f=jquery-1.2.6.js,site.js,home.js


MINIFY
URLS IN HTML

In (X)HTML files, don't forget to replace any
"&" characters with "&amp;".


SPECIFYING
ALLOWED DIRECTORIES

By default, Minify will serve any *.css/*.js files
within the DOCUMENT_ROOT. If
you'd prefer to limit Minify's access to
certain directories, set the 
$min_serveOptions['minApp']['allowDirs']
array in config.php. E.g. to limit 
to the /js and /themes/default
directories, use:

$min_serveOptions['minApp']['allowDirs'] = array('//js',
'//themes/default');


GROUPS: FASTER PERFORMANCE AND BETTER URLS

For the
best performance, edit groupsConfig.php to pre-specify groups of files 
to
be combined under preset keys. E.g., here's an example configuration in

groupsConfig.php:

return array(
    'js' => array('//js/Class.js',
'//js/email.js')
);

This pre-selects the following files to be combined
under the key "js":
  http://example.com/js/Class.js
 
http://example.com/js/email.js
  
You can now serve these files with this
simple URL:
  http://example.com/min/?g=js
  

GROUPS: SPECIFYING FILES
OUTSIDE THE DOC_ROOT

In the groupsConfig.php array, the "//" in
the file paths is a shortcut for
the DOCUMENT_ROOT, but you can also
specify paths from the root of the filesystem
or relative to the DOC_ROOT:


return array(
    'js' => array(
        '//js/file.js'            //
file within DOC_ROOT
        ,'//../file.js'           // file in parent
directory of DOC_ROOT
        ,'C:/Users/Steve/file.js' // file anywhere on
filesystem
    )
);


FAR-FUTURE EXPIRES HEADERS

Minify can send
far-future (one year) Expires headers. To enable this you must
add a number
to the querystring (e.g. /min/?g=js&1234 or /min/f=file.js&1234)

and alter it whenever a source file is changed. If you have a build
process you 
can use a build/source control revision number.

If you serve
files as a group, you can use the utility function Minify_groupUri()
to get
a "versioned" Minify URI for use in your HTML. E.g.:

<?php
//
add /min/lib to your include_path first!
require $_SERVER['DOCUMENT_ROOT']
. '/min/utils.php';

$jsUri = Minify_groupUri('js'); 
echo "<script
type='text/javascript' src='{$jsUri}'></script>";


DEBUG
MODE

In debug mode, instead of compressing files, Minify sends combined
files with
comments prepended to each line to show the line number in the
original source
file. To enable this, set $min_allowDebugFlag to true in
config.php and append
"&debug=1" to your URIs. E.g.
/min/?f=script1.js,script2.js&debug=1

Known issue: files with
comment-like strings/regexps can cause problems in this
mode.
