Autoptimize - Version 2.4.0

Version Description

  • refactored significantly (no more "classlesses", all is OO), classes are autoloaded, tests added (travis-ci) by zytzagoo who deserves praise for his hard work!
  • new: image optimization (see "Extra"-tab) using Shortpixel's smart image optimization proxy
  • new: you can now disable JS/ CSS-files being aggregated, having them minified individually instead
  • new: Google Fonts can now be "aggregated & preloaded", this uses CSS which is loaded non render-blocking
  • new: Autoptimize "listens" to page caches being cleared, upon which it purges it's own cache as well. Support depends on known action hooks firing by the page cache, supported by Hyper Cache, WP Rocket, W3 Total Cache, KeyCDN Cache Enabler, Swift, WP Super Cache, WP Fastest Cache and Comet Cache.
  • new: local JS/ CSS-files that are excluded from optimization are minified by default (can be overridden by filter)
  • improvement: updated minifiers (with very significant improvements for YUI CSS compressor PHP port)
  • improvement: "remove all Google Fonts" is now more careful (avoiding removing entire CSS blocks)
  • misc. under the hood improvements (e.g. more robust cache clearing, better support for multibyte character sets, improved CDN rewrite logic, avoid PHP warnings when writing files to cache, ...)

- * JSMin.php - modified PHP implementation of Douglas Crockford's JSMin.

- *
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.

2
+ [![Latest Stable Version](https://poser.pugx.org/collizo4sky/persist-admin-notices-dismissal/v/stable)](https://packagist.org/packages/collizo4sky/persist-admin-notices-dismissal)
3
+ [![Total Downloads](https://poser.pugx.org/collizo4sky/persist-admin-notices-dismissal/downloads)](https://packagist.org/packages/collizo4sky/persist-admin-notices-dismissal)
4
+
5
+ Simple framework library that persists the dismissal of admin notices across pages in WordPress dashboard.
6
+
7
+ ## Installation
8
+
9
+ Run `composer require collizo4sky/persist-admin-notices-dismissal`
10
+
11
+ Alternatively, clone or download this repo into the `vendor/` folder in your plugin, and include/require the `persist-admin-notices-dismissal.php` file like so
12
+
13
+ ```php
14
+ require __DIR__ . '/vendor/persist-admin-notices-dismissal/persist-admin-notices-dismissal.php';
15
+ add_action( 'admin_init', array( 'PAnD', 'init' ) );
16
+ ```
17
+
18
+ or let Composer's autoloader do the work.
19
+
20
+ ## How to Use
21
+ Firstly, install and activate this library within a plugin.
22
+
23
+ Say you have the following markup as your admin notice,
24
+
25
+
26
+ ```php
27
+ function sample_admin_notice__success() {
28
+ ?>
29
+ <div class="updated notice notice-success is-dismissible">
30
+ <p><?php _e( 'Done!', 'sample-text-domain' ); ?></p>
31
+ </div>
32
+ <?php
33
+ }
34
+ add_action( 'admin_notices', 'sample_admin_notice__success' );
35
+ ```
36
+
37
+ To make it hidden forever when dismissed, add the following data attribute `data-dismissible="disable-done-notice-forever"` to the div markup like so:
38
+
39
+
40
+ ```php
41
+ function sample_admin_notice__success() {
42
+ if ( ! PAnD::is_admin_notice_active( 'disable-done-notice-forever' ) ) {
43
+ return;
44
+ }
45
+
46
+ ?>
47
+ <div data-dismissible="disable-done-notice-forever" class="updated notice notice-success is-dismissible">
48
+ <p><?php _e( 'Done!', 'sample-text-domain' ); ?></p>
49
+ </div>
50
+ <?php
51
+ }
52
+ add_action( 'admin_init', array( 'PAnD', 'init' ) );
53
+ add_action( 'admin_notices', 'sample_admin_notice__success' );
54
+ ```
55
+
56
+ ## Autoloaders
57
+ When using the framework with an autoloader you **must** also load the class outside of the `admin_notices` or `network_admin_notices` hooks. The reason is that these hooks come after the `admin_enqueue_script` hook that loads the javascript.
58
+
59
+ Just add the following in your main plugin file.
60
+
61
+ ```php
62
+ add_action( 'admin_init', array( 'PAnD', 'init' ) );
63
+ ```
64
+
65
+ #### Usage Instructions and Examples
66
+ If you have two notices displayed when certain actions are triggered; firstly, choose a string to uniquely identify them, e.g. `notice-one` and `notice-two`
67
+
68
+ To make the first notice never appear once dismissed, its `data-dismissible` attribute will be `data-dismissible="notice-one-forever"` where `notice-one` is its unique identifier and `forever` is the dismissal time period.
69
+
70
+ To make the second notice only hidden for 2 days, its `data-dismissible` attribute will be `data-dismissible="notice-two-2"` where `notice-two` is its unique identifier and the `2`, the number of days it will be hidden is the dismissal time period.
71
+
72
+ You **must** append the dismissal time period to the end of your unique identifier with a hyphen (`-`) and this value must be an integer. The only exception is the string `forever`.
73
+
74
+ To actually make the dismissed admin notice not to appear, use the `is_admin_notice_active()` function like so:
75
+
76
+
77
+ ```php
78
+ function sample_admin_notice__success1() {
79
+ if ( ! PAnD::is_admin_notice_active( 'notice-one-forever' ) ) {
80
+ return;
81
+ }
82
+
83
+ ?>
84
+ <div data-dismissible="notice-one-forever" class="updated notice notice-success is-dismissible">
85
+ <p><?php _e( 'Done 1!', 'sample-text-domain' ); ?></p>
86
+ </div>
87
+ <?php
88
+ }
89
+
90
+ function sample_admin_notice__success2() {
91
+ if ( ! PAnD::is_admin_notice_active( 'notice-two-2' ) ) {
92
+ return;
93
+ }
94
+
95
+ ?>
96
+ <div data-dismissible="notice-two-2" class="updated notice notice-success is-dismissible">
97
+ <p><?php _e( 'Done 2!', 'sample-text-domain' ); ?></p>
98
+ </div>
99
+ <?php
100
+ }
101
+
102
+ add_action( 'admin_init', array( 'PAnD', 'init' ) );
103
+ add_action( 'admin_notices', 'sample_admin_notice__success1' );
104
+ add_action( 'admin_notices', 'sample_admin_notice__success2' );
105
+ ```
106
+
107
+
108
+ Cool beans. Isn't it?

  == Description ==
12
 
13
- Autoptimize makes optimizing your site really easy. It can aggregate, minify and cache scripts and styles, injects CSS in the page head by default (but can also defer), moves and defers scripts to the footer and minifies HTML. The "Extra" options allow you to async non-aggregated JavaScript, remove WordPress core emoji cruft, optimize Google Fonts and more. As such it can improve your site's performance even when already on HTTP/2! There is extensive API available to enable you to tailor Autoptimize to each and every site's specific needs.
14
 
15
  If you consider performance important, you really should use one of the many caching plugins to do page caching. Some good candidates to complement Autoptimize that way are e.g. [WP Super Cache](http://wordpress.org/plugins/wp-super-cache/), [HyperCache](http://wordpress.org/plugins/hyper-cache/), [Comet Cache](https://wordpress.org/plugins/comet-cache/) or [KeyCDN's Cache Enabler](https://wordpress.org/plugins/cache-enabler).

- HTTP/2 is a great step forward for sure, reducing the impact of multiple requests from the same server significantly by using the same connection to perform several concurrent requests. That being said, [concatenation of CSS/ JS can still make a lot of sense](http://engineering.khanacademy.org/posts/js-packaging-http2.htm), as described in [this css-tricks.com article](https://css-tricks.com/http2-real-world-performance-test-analysis/) and this [blogpost from one of the Ebay engineers](http://calendar.perfplanet.com/2015/packaging-for-performance/). The conclusion; configure, test, reconfigure, retest, tweak and look what works best in your context. Maybe it's just HTTP/2, maybe it's HTTP/2 + aggregation and minification, maybe it's HTTP/2 + minification (which AO can do as well).

152
- In some rare cases the [CSS minification component](https://github.com/tubalmartin/YUI-CSS-compressor-PHP-port/) currently used by Autoptimize crashes due to a lack of resources (see [detailed technical explanation here](http://blog.futtta.be/2014/01/14/irregular-expressions-have-your-stack-for-lunch/)). You can in that case either disable CSS optimization, try to exclude specific CSS from being aggregated or activate the legacy minifiers which don't have that problem. The latter can be accomplished by adding this to your wp-config.php:

- Google Fonts are typically loaded by a "render blocking" linked CSS-file. If you have a theme and plugins that use Google Fonts, you might end up with multiple such CSS-files. Autoptimize (since version 2.3) now let's you lessen the impact of Google Fonts by either removing them alltogether or by optimizing the way they are loaded. There are two optimization-flavors; the first one is "combine and link", which replaces all requests for Google Fonts into one request, which will still be render-blocking but will allow the fonts to be loaded immediately (meaning you won't see fonts change while the page is loading). The alternative is "combine and load async" which uses JavaScript to load the fonts in a non-render blocking manner but which might cause a "flash of unstyled text".

  JavaScript files that are not autoptimized (because they were excluded or because they are hosted elsewhere) are typically render-blocking. By adding them in the comma-separated "async JS" field, Autoptimize will add the async flag causing the browser to load those files asynchronously (i.e. non-render blocking). This can however break your site (page), e.g. if you async "js/jquery/jquery.js" you will very likely get "jQuery is not defined"-errors. Use with care.

+ Autoptimize speeds up your website by optimizing JS, CSS, HTML, Google Fonts and images, async-ing JS, removing emoji cruft and more.

  == Description ==
13
 
14
+ Autoptimize makes optimizing your site really easy. It can aggregate, minify and cache scripts and styles, injects CSS in the page head by default (but can also defer), moves and defers scripts to the footer and minifies HTML. The "Extra" options allow you to optimize Google Fonts and images, async non-aggregated JavaScript, remove WordPress core emoji cruft and more. As such it can improve your site's performance even when already on HTTP/2! There is extensive API available to enable you to tailor Autoptimize to each and every site's specific needs.
15
 
16
  If you consider performance important, you really should use one of the many caching plugins to do page caching. Some good candidates to complement Autoptimize that way are e.g. [WP Super Cache](http://wordpress.org/plugins/wp-super-cache/), [HyperCache](http://wordpress.org/plugins/hyper-cache/), [Comet Cache](https://wordpress.org/plugins/comet-cache/) or [KeyCDN's Cache Enabler](https://wordpress.org/plugins/cache-enabler).

37
  = But I'm on HTTP/2, so I don't need Autoptimize? =
38
 
39
+ HTTP/2 is a great step forward for sure, reducing the impact of multiple requests from the same server significantly by using the same connection to perform several concurrent requests. That being said, [concatenation of CSS/ JS can still make a lot of sense](http://engineering.khanacademy.org/posts/js-packaging-http2.htm), as described in [this css-tricks.com article](https://css-tricks.com/http2-real-world-performance-test-analysis/) and this [blogpost from one of the Ebay engineers](http://calendar.perfplanet.com/2015/packaging-for-performance/). The conclusion; configure, test, reconfigure, retest, tweak and look what works best in your context. Maybe it's just HTTP/2, maybe it's HTTP/2 + aggregation and minification, maybe it's HTTP/2 + minification (which AO can do as well, simply untick the "aggregate JS-files" and/ or "aggregate CSS-files" options).
40
 
41
  = Will this work with my blog? =
42
 
135
 
136
  = Configuring & Troubleshooting Autoptimize =
137
 
138
+ After having installed and activated the plugin, you'll have access to an admin page where you can to enable HTML, CSS and JavaScript optimization. According to your liking, you can start of just enabling all of them, or if you're more cautious one at a time.
139
 
140
  If your blog doesn't function normally after having turned on Autoptimize, here are some pointers to identify & solve such issues using "advanced settings":
141
 
148
 
149
  = Help, I have a blank page or an internal server error after enabling Autoptimize!! =
150
 
151
+ Make sure you're not running other HTML, CSS or JS minification plugins (BWP minify, WP minify, ...) simultaneously with Autoptimize or disable that functionality your page caching plugin (W3 Total Cache, WP Fastest Cache, ...). Try enabling only CSS or only JS optimization to see which one causes the server error and follow the generic troubleshooting steps to find a workaround.
 
 
 
 
 
 
152
 
153
  = But I still have blank autoptimized CSS or JS-files! =
154
 
191
  = What is noptimize? =
192
 
193
  Starting with version 1.6.6 Autoptimize excludes everything inside noptimize tags, e.g.:
194
+ `&lt;!--noptimize-->&lt;script>alert('this will not get autoptimized');&lt;/script>&lt;!--/noptimize-->`
 
195
 
196
  You can do this in your page/ post content, in widgets and in your theme files (consider creating [a child theme](http://codex.wordpress.org/Child_Themes) to avoid your work being overwritten by theme updates).
197
 
198
  = Can I change the directory & filename of cached autoptimize files? =
199
 
200
+ Yes, if you want to serve files from e.g. /wp-content/resources/aggregated_12345.css instead of the default /wp-content/cache/autoptimize/autoptimize_12345.css, then add this to wp-config.php:
201
  `
202
  define('AUTOPTIMIZE_CACHE_CHILD_DIR','/resources/');
203
  define('AUTOPTIMIZE_CACHEFILE_PREFIX','aggregated_');
207
 
208
  Yes, but this is off by default. You can enable this by passing ´true´ to ´autoptimize_filter_cache_create_static_gzip´. You'll obviously still have to configure your webserver to use these files instead of the non-gzipped ones to avoid the overhead of on-the-fly compression.
209
 
210
+ = What does "remove emojis" do? =
211
 
212
  This new option in Autoptimize 2.3 removes the inline CSS, inline JS and linked JS-file added by WordPress core. As such is can have a small positive impact on your site's performance.
213
 
217
 
218
  = (How) should I optimize Google Fonts? =
219
 
220
+ Google Fonts are typically loaded by a "render blocking" linked CSS-file. If you have a theme and plugins that use Google Fonts, you might end up with multiple such CSS-files. Autoptimize (since version 2.3) now let's you lessen the impact of Google Fonts by either removing them alltogether or by optimizing the way they are loaded. There are two optimization-flavors; the first one is "combine and link", which replaces all requests for Google Fonts into one request, which will still be render-blocking but will allow the fonts to be loaded immediately (meaning you won't see fonts change while the page is loading). The alternative is "combine and load async" which uses JavaScript to load the fonts in a non-render blocking manner but which might cause a "flash of unstyled text". Starting form Autopitimize 2.4 "aggregate & preload" allows to aggregate all Google Font-files in one CSS-file that is preloaded, which should not be considered render blocking, but the fonts are available sooner (so less of a flash of unstyled text).
221
 
222
  = Should I use "preconnect" =
223
 
227
 
228
  JavaScript files that are not autoptimized (because they were excluded or because they are hosted elsewhere) are typically render-blocking. By adding them in the comma-separated "async JS" field, Autoptimize will add the async flag causing the browser to load those files asynchronously (i.e. non-render blocking). This can however break your site (page), e.g. if you async "js/jquery/jquery.js" you will very likely get "jQuery is not defined"-errors. Use with care.
229
 
230
+ = How does image optimization work? =
231
+
232
+ When image optimization is on, Autoptimize will look for png, gif, jpeg (.jpg) files in image tags and in your CSS files that are loaded from your own domain and change the src (source) to the ShortPixel CDN for those.
233
+
234
+ = Where can I get more info on image optimization? =
235
+
236
+ Have a look at [Shortpixel's FAQ](https://shortpixel.helpscoutdocs.com/category/60-shortpixel-ai-cdn).
237
+
238
+ = Can I disable the minification of excluded JS/ CSS? =
239
+
240
+ As from AO 2.4 excluded JS/ CSS are minified if the (filename indicates the) file is not minified yet. You can disable this with these filters;
241
+
242
+ `
243
+ add_filter('autoptimize_filter_js_minify_excluded','__return_false');
244
+ add_filter('autoptimize_filter_css_minify_excluded','__return_false');`
245
+
246
+ = Can I disable AO listening to page cache purges? =
247
+
248
+ As from AO 2.4 AO "listens" to page cache purges to clear its own cache. You can disable this behavior with this filter;
249
+
250
+ `
251
+ add_filter('autoptimize_filter_main_hookpagecachepurge','__return_false');`
252
+
253
+ = Why can't I upgrade from 2.3.4 to 2.4.0 (or higher)? =
254
+
255
+ Main reason (apart from occasional hickups that seem to be inherent to plugin upgrades) is that AO 2.4 requires you to be running PHP 5.3 or higher. And let's face it; you should actually be running PHP 7.x if you value performance (and security and support), no?
256
+
257
  = Where can I get help? =
258
 
259
  You can get help on the [wordpress.org support forum](http://wordpress.org/support/plugin/autoptimize). If you are 100% sure this your problem cannot be solved using Autoptimize configuration and that you in fact discovered a bug in the code, you can [create an issue on GitHub](https://github.com/futtta/autoptimize/issues).

271
  == Changelog ==
272
 
273
+ = 2.4.0 =
274
+ * refactored significantly (no more "classlesses", all is OO), classes are autoloaded, tests added (travis-ci) by zytzagoo who deserves praise for his hard work!
275
+ * new: image optimization (see "Extra"-tab) using Shortpixel's smart image optimization proxy
276
+ * new: you can now disable JS/ CSS-files being aggregated, having them minified individually instead
277
+ * new: Google Fonts can now be "aggregated & preloaded", this uses CSS which is loaded non render-blocking
278
+ * new: Autoptimize "listens" to page caches being cleared, upon which it purges it's own cache as well. Support depends on known action hooks firing by the page cache, supported by Hyper Cache, WP Rocket, W3 Total Cache, KeyCDN Cache Enabler, Swift, WP Super Cache, WP Fastest Cache and Comet Cache.
279
+ * new: local JS/ CSS-files that are excluded from optimization are minified by default (can be overridden by filter)
280
+ * improvement: updated minifiers (with very significant improvements for YUI CSS compressor PHP port)
281
+ * improvement: "remove all Google Fonts" is now more careful (avoiding removing entire CSS blocks)
282
+ * misc. under the hood improvements (e.g. more robust cache clearing, better support for multibyte character sets, improved CDN rewrite logic, avoid PHP warnings when writing files to cache, ...)

306
  * new: Async JS, can be applied to local or 3rd party JS (if local it will be auto-excluded from autoptimization)
307
  * new: support to tell browsers to preconnect (= dns lookup + tcp/ip connection + ssl negotiation) to 3rd party domains (depends on browser support, works in Chrome & Firefox)
308
+ * new: remove WordPress' core's emoji CSS & JS
309
  * new: remove (version parameter from) Querystring

325
  * new: option to enable/ disable AO for logged in users (on by default)
326
  * new: option to enable/ disable AO on WooCommerce, Easy Digital Downloads or WP eCommerce cart/ checkout page (on by default)

328
  * improvement: switched to YUI CSS minifier PHP-port 2.8.4-p10 (so not to the 3.x branch yet)
329
  * improvements to the logic of which JS/ CSS can be optimized (getPath function) increasing reliability of the aggregation process
330

343
  * new: Autoptimize now appears in admin-toolbar with an easy view on cache size and the possibility to purge the cache (pass `false` to `autoptimize_filter_toolbar_show` filter to disable), a big thanks to [Pablo Custo](https://github.com/pablocusto) for his hard work on this nice feature!
344
+ * new: An extra "More Optimization"-tab is shown (can be hidden with ´autoptimize_filter_show_partner_tabs´-filter) with information about related optimization tools- and services.
345
  * new: If cache size becomes too big, a mail will be sent to the site admin (pass `false` to `autoptimize_filter_cachecheck_sendmail` filter to disable or pass alternative email to the `autoptimize_filter_cachecheck_mailto` filter to change email-address)
346
  * new: power-users can enable Autoptimize to pre-gzip the autoptimized files by passing `true` to `autoptimize_filter_cache_create_static_gzip`, kudo's to (Draikin)[https://github.com/Draikin] for this!
347
  * improvement: admin GUI updated (again; thanks Pablo!) with some responsiveness added in the mix (not showing the right hand column on smaller screen-sizes)
379
