This plugin will compress your HTML by shortening **URLs** and removing **standard comments** and **whitespace**; including new lines, carriage returns, tabs and excess spaces. Most importantly, by ignoring `<pre>`, `<textarea>`, `<script>` and Explorer® `conditional comment` tags, ***presentation will not be affected***. == Installation == 1. Download the plugin (zip file). 2. Upload and activate the plugin through the "Plugins" menu in the WordPress admin. == Frequently Asked Questions == = Will this plugin slow down my page load times? = Yes, slightly. While you should be using **[WP Super Cache](http://wordpress.org/extend/plugins/wp-super-cache/)** anyway, it will correct the issue. = Will Internet Explorer conditional comments be removed? = No. = Is this plugin HTML5-compatible? = Yes. = Will having invalid HTML cause an issue? = Probably, however WordPress does a pretty good job of correcting invalid markup. But honestly, it's your job to make sure that your code doesn't suck. = Will this plugin interfere with my hash-based JavaScript navigation? = If the links in your HTML are *not* hard-coded as hashes without the use of a script, an issue could occur with URL shortening. If so, setting `$shorten_urls` on line `21` of *libs/html-minify.php* to `false` will fix that. = My URLs have the "http:" and/or "https:" stripped?? = This is totally fine and actually intentional. It's standard and will not cause 404s nor get in the way of your SEO, but it *will* lower file size! You might be interested in reading more about this technique, called **[scheme-relative URLs](http://paulirish.com/2010/the-protocol-relative-url/)**. = Why does my compressed HTML have a space between most tags? = To preserve *rendered* whitespace. One or more line breaks in your markup are rendered as a single space in a web browser. Visual discrepancies would occur if those line breaks were not converted to at least one space. = How do I mark areas that should not be compressed? = While <pre>, <textarea> and <script> tags are automatically left uncompressed, you can designate any code to be exempted from compression. Simply drop your content between a pair of `<!--wp-html-compression no compression-->` comment tags. A picture is worth a thousand words; so, check the **[screenshots](http://wordpress.org/extend/plugins/wp-html-compression/screenshots/)**. = How do I compress the contents of <script> tags? = Until a settings page is created, you'll have to edit the file from the "Plugins" menu in the WordPress admin. Set `$compress_js` on line `21` of *libs/html-minify.php* to `true`. **This is not recommended** as this plugin is not yet ready to *properly* compress inline scripts. = Are you or have you thought of using HTML Tidy? = Since not every WordPress server supports the installation of PHP extensions, this plugin does not currently make use of HTML Tidy. However, future releases may do so. = Will this plugin work for WordPress version x.x.x? = This plugin has only been tested with versions of WordPress as early as 3.2. For anything older, you'll have to see for yourself. == Screenshots == 1. This is what the XHTML looks like after being compressed with WP-HTML-Compression. 2. This is what the same XHTML from the above screenshot looked like prior to compression. 3. This is an example of how to use the compression override. == Changelog == = 0.5.8 = * URLs within `<script>` and `<style>` tags are no longer shortened unless compression on such tags has been enabled = 0.5.7 = * Upgraded to **[Absolute-to-Relative URLs](http://wordpress.org/extend/plugins/absolute-to-relative-urls/)** v0.3.4 * Empty, hash-only anchors (`"#"`) are no longer invalidated by the URL shortener * Bypasses compression for **[Humans TXT](http://wordpress.org/extend/plugins/humanstxt/)** output = 0.5.6 = * Upgraded to **[Absolute-to-Relative URLs](http://wordpress.org/extend/plugins/absolute-to-relative-urls/)** v0.3.3 * Javascript URIs (`"javascript:"`) are no longer invalidated by the URL shortener * Minor cleanup = 0.5.5.1 = * Oops, minor slip-up = 0.5.5 = * Upgraded to **[Absolute-to-Relative URLs](http://wordpress.org/extend/plugins/absolute-to-relative-urls/)** v0.3.2 * Data URIs (`"data:"`) are no longer invalidated by the URL shortener * URL shortener now applied to `data` attribute values (common to `<object>`) * Minor bug prevention = 0.5.4.2 = * PHP errors hidden if/when plugin file is accessed directly = 0.5.4.1 = * Fixed typo on variable = 0.5.4 = * Plugin should always load now, even for installations that seem to skip the execution of `template_redirect` (?) * Converted for use in standard PHP as **[HTML Minify](http://www.svachon.com/blog/html-minify/)**, for which this plugin now simply wraps * Compression statistics comment disabled by default = 0.5.3 = * Bypasses compression for robots.txt * Corrected "invalid plugin header" issue when activating from install screen = 0.5.2 = * Upgraded to **[Absolute-to-Relative URLs](http://wordpress.org/extend/plugins/absolute-to-relative-urls/)** v0.3.1 = 0.5.1 = * Upgraded to **[Absolute-to-Relative URLs](http://wordpress.org/extend/plugins/absolute-to-relative-urls/)** v0.3 * JavaScript library references with scheme-relative URLs (`//domain.com/`) are no longer broken * Canonical URL no longer shortened * Minor bug fixes = 0.5 = * Includes **[Absolute-to-Relative URLs](http://wordpress.org/extend/plugins/absolute-to-relative-urls/)** for `action`, `href`, `src` attributes * Bypasses compression for RSS/Atom feeds * Bypasses compression on admin/dashboard pages to free up resources for other tools/plugins * Compresses themes that don't make use of a header.php file (previously did not) * Removes any empty attributes using single-quote encapsulation (previously supported only double-quotes) * Removes excess spacing within opening and closing tags (previously supported only self-closing tags) * Converts new lines to spaces so that *rendered* whitespace is preserved * Simplified compression statistics comment * PHP errors hidden if/when plugin file is accessed directly * Speed optimizations = 0.4 = * Removes empty attributes except `action`, `alt`, `content`, `src` = 0.3 = * Comments in <textarea> are no longer removed.
