<h2>Minify URI</h2>

<h2>How to serve these files as a group</h2>
|
| 127 |
+
<p>For the best performance you can serve these files as a pre-defined group with a URI
|
| 128 |
+
like: <code><span class=minRoot>/min/?</span>g=keyName</code></p>
|
| 129 |
+
<p>To do this, add a line like this to /min/groupsConfig.php:</p>
|
| 130 |
+
|
| 131 |
+
<pre><code>return array(
|
| 132 |
+
<span style="color:#666">... your existing groups here ...</span>
|
| 133 |
+
<input id=groupConfig size=100 type=text readonly>
|
| 134 |
+
);</code></pre>
|
| 135 |
+
|
| 136 |
+
<p><em>Make sure to replace <code>keyName</code> with a unique key for this group.</em></p>
|
| 137 |
+
</div>
|
| 138 |
+
|
| 139 |
+
<div id=getBm>
|
| 140 |
+
<h3>Find URIs on a Page</h3>
|
| 141 |
+
<p>You can use the bookmarklet below to fetch all CSS & Javascript URIs from a page
|
| 142 |
+
on your site. When you active it, this page will open in a new window with a list of
|
| 143 |
+
available URIs to add.</p>
|
| 144 |
+
|
| 145 |
+
<p><a id=bm>Create Minify URIs</a> <small>(right-click, add to bookmarks)</small></p>
|
| 146 |
+
</div>
|
| 147 |
+
|
| 148 |
+
<h3>Combining CSS files that contain <code>@import</code></h3>
|
| 149 |
+
<p>If your CSS files contain <code>@import</code> declarations, Minify will not
|
| 150 |
+
remove them. Therefore, you will want to remove those that point to files already
|
| 151 |
+
in your list, and move any others to the top of the first file in your list
|
| 152 |
+
(imports below any styles will be ignored by browsers as invalid).</p>
|
| 153 |
+
<p>If you desire, you can use Minify URIs in imports and they will not be touched
|
| 154 |
+
by Minify. E.g. <code>@import "<span class=minRoot>/min/?</span>g=css2";</code></p>
|
| 155 |
+
|
| 156 |
+
<h3>Debug Mode</h3>
|
| 157 |
+
<p>When /min/config.php has <code>$min_allowDebugFlag = <strong>true</strong>;</code>
|
| 158 |
+
you can get debug output by appending <code>&debug</code> to a Minify URL, or
|
| 159 |
+
by sending the cookie <code>minDebug=<match></code>, where <code><match></code>
|
| 160 |
+
should be a string in the Minify URIs you'd like to debug. This bookmarklet will allow you to
|
| 161 |
+
set this cookie.</p>
|
| 162 |
+
<p><a id=bm2>Minify Debug</a> <small>(right-click, add to bookmarks)</small></p>

| 1018 |
+
* Converts to and from JSON format.
|
| 1019 |
+
*
|
| 1020 |
+
* JSON (JavaScript Object Notation) is a lightweight data-interchange
|
| 1021 |
+
* format. It is easy for humans to read and write. It is easy for machines
|
| 1022 |
+
* to parse and generate. It is based on a subset of the JavaScript
|
| 1023 |
+
* Programming Language, Standard ECMA-262 3rd Edition - December 1999.
|
| 1024 |
+
* This feature can also be found in Python. JSON is a text format that is
|
| 1025 |
+
* completely language independent but uses conventions that are familiar
|
| 1026 |
+
* to programmers of the C-family of languages, including C, C++, C#, Java,
|
| 1027 |
+
* JavaScript, Perl, TCL, and many others. These properties make JSON an
|
| 1028 |
+
* ideal data-interchange language.
|
| 1029 |
+
*
|
| 1030 |
+
* This package provides a simple encoder and decoder for JSON notation. It
|
| 1031 |
+
* is intended for use with client-side Javascript applications that make
|
| 1032 |
+
* use of HTTPRequest to perform server communication functions - data can
|
| 1033 |
+
* be encoded into JSON notation for use in a client-side javascript, or
|
| 1034 |
+
* decoded from incoming Javascript requests. JSON format is native to
|
| 1035 |
+
* Javascript, and can be directly eval()'ed with no further parsing
|
| 1036 |
+
* overhead
|
| 1037 |
+
*
|
| 1038 |
+
* All strings should be in ASCII or UTF-8 format!

/**
|
| 3 |
+
* JSMin.php - modified PHP implementation of Douglas Crockford's JSMin.
|
| 4 |
+
*
|
| 5 |
+
* <code>
|
| 6 |
+
* $minifiedJs = JSMin::minify($js);
|
| 7 |
+
* </code>
|
| 8 |
+
*
|
| 9 |
+
* This is a modified port of jsmin.c. Improvements:
|
| 10 |
+
*
|
| 11 |
+
* Does not choke on some regexp literals containing quote characters. E.g. /'/
|
| 12 |
+
*
|
| 13 |
+
* Spaces are preserved after some add/sub operators, so they are not mistakenly
|
| 14 |
+
* converted to post-inc/dec. E.g. a + ++b -> a+ ++b
|
| 15 |
+
*
|
| 16 |
+
* Preserves multi-line comments that begin with /*!
|
| 17 |
+
*
|
| 18 |
+
* PHP 5 or higher is required.

* Serve a request for a minified file.
|
| 91 |
+
*
|
| 92 |
+
* Here are the available options and defaults in the base controller:
|
| 93 |
+
*
|
| 94 |
+
* 'isPublic' : send "public" instead of "private" in Cache-Control
|
| 95 |
+
* headers, allowing shared caches to cache the output. (default true)
|
| 96 |
+
*
|
| 97 |
+
* 'quiet' : set to true to have serve() return an array rather than sending
|
| 98 |
+
* any headers/output (default false)
|
| 99 |
+
*
|
| 100 |
+
* 'encodeOutput' : set to false to disable content encoding, and not send
|
| 101 |
+
* the Vary header (default true)
|
| 102 |
+
*
|
| 103 |
+
* 'encodeMethod' : generally you should let this be determined by
|
| 104 |
+
* HTTP_Encoder (leave null), but you can force a particular encoding
|
| 105 |
+
* to be returned, by setting this to 'gzip' or '' (no encoding)
|
| 106 |
+
*
|
| 107 |
+
* 'encodeLevel' : level of encoding compression (0 to 9, default 9)
|
| 108 |
+
*
|
| 109 |
+
* 'contentTypeCharset' : appended to the Content-Type header sent. Set to a falsey
|
| 110 |
+
* value to remove. (default 'utf-8')
|
| 111 |
+
*
|
| 112 |
+
* 'maxAge' : set this to the number of seconds the client should use its cache
|
| 113 |
+
* before revalidating with the server. This sets Cache-Control: max-age and the
|
| 114 |
+
* Expires header. Unlike the old 'setExpires' setting, this setting will NOT
|
| 115 |
+
* prevent conditional GETs. Note this has nothing to do with server-side caching.
|
| 116 |
+
*
|
| 117 |
+
* 'rewriteCssUris' : If true, serve() will automatically set the 'currentDir'
|
| 118 |
+
* minifier option to enable URI rewriting in CSS files (default true)
|
| 119 |
+
*
|
| 120 |
+
* 'bubbleCssImports' : If true, all @import declarations in combined CSS
|
| 121 |
+
* files will be move to the top. Note this may alter effective CSS values
|
| 122 |
+
* due to a change in order. (default false)
|
| 123 |
+
*
|
| 124 |
+
* 'debug' : set to true to minify all sources with the 'Lines' controller, which
|
| 125 |
+
* eases the debugging of combined files. This also prevents 304 responses.
|
| 126 |
+
* @see Minify_Lines::minify()
|
| 127 |
+
*
|
| 128 |
+
* 'minifiers' : to override Minify's default choice of minifier function for
|
| 129 |
+
* a particular content-type, specify your callback under the key of the
|
| 130 |
+
* content-type:
|
| 131 |
+
* <code>
|
| 132 |
+
* // call customCssMinifier($css) for all CSS minification
|
| 133 |
+
* $options['minifiers'][Minify::TYPE_CSS] = 'customCssMinifier';
|
| 134 |
+
*
|
| 135 |
+
* // don't minify Javascript at all
|
| 136 |
+
* $options['minifiers'][Minify::TYPE_JS] = '';
|
| 137 |
+
* </code>
|
| 138 |
+
*
|
| 139 |
+
* 'minifierOptions' : to send options to the minifier function, specify your options
|
| 140 |
+
* under the key of the content-type. E.g. To send the CSS minifier an option:
|
| 141 |
+
* <code>
|
| 142 |
+
* // give CSS minifier array('optionName' => 'optionValue') as 2nd argument
|
| 143 |
+
* $options['minifierOptions'][Minify::TYPE_CSS]['optionName'] = 'optionValue';
|
| 144 |
+
* </code>
|
| 145 |
+
*
|
| 146 |
+
* 'contentType' : (optional) this is only needed if your file extension is not
|
| 147 |
+
* js/css/html. The given content-type will be sent regardless of source file
|
| 148 |
+
* extension, so this should not be used in a Groups config with other
|
| 149 |
+
* Javascript/CSS files.
