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 "&".
|
||||
|
||||
|
||||
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.

<h2>Minify URI</h2>

|
||||
with cache headers.</p>

|

|

<h2>How to serve these files as a group</h2>
|
||||
<p>For the best performance you can serve these files as a pre-defined group with a URI
|
||||
like: <code><span class=minRoot>/min/?</span>g=keyName</code></p>
|
||||
<p>To do this, add a line like this to /min/groupsConfig.php:</p>
|
||||
|
||||
<pre><code>return array(
|
||||
<span style="color:#666">... your existing groups here ...</span>
|
||||
<input id=groupConfig size=100 type=text readonly>
|
||||
);</code></pre>
|
||||
|
||||
<p><em>Make sure to replace <code>keyName</code> with a unique key for this group.</em></p>
|
||||
</div>
|
||||

||||
<div id=getBm>
|
||||
<h3>Find URIs on a Page</h3>
|
||||
<p>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.</p>
|
||||
|
||||
<p><a id=bm>Create Minify URIs</a> <small>(right-click, add to bookmarks)</small></p>
|
||||
</div>
|
||||
|
||||
<h3>Combining CSS files that contain <code>@import</code></h3>
|
||||
<p>If your CSS files contain <code>@import</code> 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).</p>
|
||||
<p>If you desire, you can use Minify URIs in imports and they will not be touched
|
||||
by Minify. E.g. <code>@import "<span class=minRoot>/min/?</span>g=css2";</code></p>

* comments that begin with "/*!" (for documentation purposes). In the latter case

* Here are the available options and defaults in the base controller:
|
||||
*
|
||||
* 'isPublic' : send "public" instead of "private" in Cache-Control
|
||||
* headers, allowing shared caches to cache the output. (default true)
|
||||
*
|
||||
* 'quiet' : set to true to have serve() return an array rather than sending
|
||||
* any headers/output (default false)
|
||||
*
|
||||
* 'encodeOutput' : set to false to disable content encoding, and not send
|
||||
* the Vary header (default true)
|
||||
*
|
||||
* 'encodeMethod' : generally you should let this be determined by
|
||||
* HTTP_Encoder (leave null), but you can force a particular encoding
|
||||
* to be returned, by setting this to 'gzip' or '' (no encoding)
|
||||
*
|
||||
* 'encodeLevel' : level of encoding compression (0 to 9, default 9)
|
||||
*
|
||||
* 'contentTypeCharset' : appended to the Content-Type header sent. Set to a falsey
|
||||
* value to remove. (default 'utf-8')
|
||||
*
|
||||
* 'maxAge' : set this to the number of seconds the client should use its cache
|
||||
* before revalidating with the server. This sets Cache-Control: max-age and the
|
||||
* Expires header. Unlike the old 'setExpires' setting, this setting will NOT
|
||||
* prevent conditional GETs. Note this has nothing to do with server-side caching.
|
||||
*
|
||||
* 'rewriteCssUris' : If true, serve() will automatically set the 'currentDir'
|
||||
* minifier option to enable URI rewriting in CSS files (default true)
|
||||
*
|
||||
* 'bubbleCssImports' : If true, all @import declarations in combined CSS
|
||||
* files will be move to the top. Note this may alter effective CSS values
|
||||
* due to a change in order. (default false)
|
||||
*
|
||||
* 'debug' : set to true to minify all sources with the 'Lines' controller, which
|
||||
* eases the debugging of combined files. This also prevents 304 responses.
|
||||
* @see Minify_Lines::minify()
|
||||
*
|
||||
* 'minifiers' : to override Minify's default choice of minifier function for
|
||||
* a particular content-type, specify your callback under the key of the
|
||||
* content-type:
|
||||
* <code>
|
||||
* // call customCssMinifier($css) for all CSS minification
|
||||
* $options['minifiers'][Minify::TYPE_CSS] = 'customCssMinifier';
|
||||
*
|
||||
* // don't minify Javascript at all
|
||||
* $options['minifiers'][Minify::TYPE_JS] = '';
|
||||
* </code>
|
||||
*
|
||||
* 'minifierOptions' : to send options to the minifier function, specify your options
|
||||
* under the key of the content-type. E.g. To send the CSS minifier an option:
|
||||
* <code>
|
||||
* // give CSS minifier array('optionName' => 'optionValue') as 2nd argument
|
||||
* $options['minifierOptions'][Minify::TYPE_CSS]['optionName'] = 'optionValue';
|
||||
* </code>
|
||||
*
|
||||
* 'contentType' : (optional) this is only needed if your file extension is not
|
||||
* js/css/html. The given content-type will be sent regardless of source file
|
||||
* extension, so this should not be used in a Groups config with other
|
||||
* Javascript/CSS files.
|
||||
*
|
||||
* Any controller options are documented in that controller's setupSources() method.
