Note: Please set $min_cachePath
in /min/config.php to improve performance.

<?php endIf; ?>

Note: Your webserver does not seem to
 support mod_rewrite (used in /min/.htaccess). Your Minify URIs will contain "?", which
may reduce the benefit of proxy cache servers.

Minify URI Builder

Javascript and a browser supported by jQuery 1.2.6 is required
for this application.

Create a list of Javascript or CSS files (or 1 is fine) you'd like to combine
and click [Update].

<button>Add file +</button>

<button id=update class=hide>Update</button>

Minify URI

Place this URI in your HTML to serve the files above combined, minified, compressed and
with cache headers.

URI	/min (opens in new window)

HTML	<input id=uriHtml type=text size=100 readonly>

How to serve these files as a group

For the best performance you can serve these files as a pre-defined group with a URI
like: /min/?g=keyName

To do this, add a line like this to /min/groupsConfig.php:

return array(
    ... your existing groups here ...
<input id=groupConfig size=100 type=text readonly>
);

Make sure to replace keyName with a unique key for this group.

Find URIs on a Page

You can use the bookmarklet below to fetch all CSS & Javascript URIs from a page
on your site. When you active it, this page will open in a new window with a list of
available URIs to add.

Create Minify URIs (right-click, add to bookmarks)

Combining CSS files that contain @import

If your CSS files contain @import declarations, Minify will not
remove them. Therefore, you will want to remove those that point to files already
in your list, and move any others to the top of the first file in your list
(imports below any styles will be ignored by browsers as invalid).

If you desire, you can use Minify URIs in imports and they will not be touched
by Minify. E.g. @import "/min/?g=css2";

Need help? Search or post to the Minify discussion list.

  /**
   * Converts to and from JSON format.
   *
   * JSON (JavaScript Object Notation) is a lightweight data-interchange
   * format. It is easy for humans to read and write. It is easy for machines
   * to parse and generate. It is based on a subset of the JavaScript
   * Programming Language, Standard ECMA-262 3rd Edition - December 1999.
   * This feature can also be found in  Python. JSON is a text format that is
   * completely language independent but uses conventions that are familiar
   * to programmers of the C-family of languages, including C, C++, C#, Java,
   * JavaScript, Perl, TCL, and many others. These properties make JSON an
   * ideal data-interchange language.
   *
   * This package provides a simple encoder and decoder for JSON notation. It
   * is intended for use with client-side Javascript applications that make
   * use of HTTPRequest to perform server communication functions - data can
   * be encoded into JSON notation for use in a client-side javascript, or
   * decoded from incoming Javascript requests. JSON format is native to
   * Javascript, and can be directly eval()'ed with no further parsing
   * overhead
   *
   * All strings should be in ASCII or UTF-8 format!

/**
 * jsmin.php - PHP implementation of Douglas Crockford's JSMin.
 *
 * This is a direct port of jsmin.c to PHP with a few PHP performance tweaks and
 * modifications to preserve some comments (see below). Also, rather than using
 * stdin/stdout, JSMin::minify() accepts a string as input and returns another
 * string as output.
 *
 * Comments containing IE conditional compilation are preserved, as are multi-line
 * comments that begin with "/*!" (for documentation purposes). In the latter case
 * newlines are inserted around the comment to enhance readability.
 *
 * PHP 5 or higher is required.
 *
 * Permission is hereby granted to use this version of the library under the
 * same terms as jsmin.c, which has the following license:
