=====================================

Simple CodeIgniter library to compress CSS and JavaScript files on the fly.

Library is based on few other scripts like http://code.google.com/p/minify/ or https://code.google.com/p/cssmin to minify CSS and it uses Google Closure compiler to compress JavaScript

###INSTALATION: Just put Minify.php file in libraries path, and create config file on config directory.

###USING THE LIBRARY:

####Configure the library: All directories needs to be writable.

// output path where the compiled files will be stored
$config['assets_dir'] = 'assets/'; 	

// where to look for css files 
$config['css_dir'] = 'assets/css';

// where to look for js files 
$config['js_dir'] = 'assets/js'; 

// compression engine setting
$config['compression_engine'] = array(
	'css' => 'minify', // minify || cssmin
	'js'  => 'closurecompiler' // jsmin || closurecompiler || jsminplus
);

####Available engines CSS - minify or cssmin - both of them are local, just try out which one is better for you, JS - closurecompiler makes API call to external server, it's slower then regular inline engine, but it's super efficient with compression, jsmin and jsminplus are local

####Run the library In the controller

//load the library
$this->load->library('minify'); 

In view

// add css files
$this->minify->css(array('reset.css', 'style.css', 'tinybox.css')); 

// add js files
$this->minify->js(array('html5.js', 'main.js')); 

// bool argument for rebuild css (false means skip rebuilding). 
echo $this->minify->deploy_css(TRUE);

//Output: '<link href="path-to-compiled-css" rel="stylesheet" type="text/css" />'

// rebuild js (false means skip rebuilding).
echo $this->minify->deploy_js(); 

//Output: '<script type="text/javascript" src="path-to-compiled-js"></script>'.

• Closure compilerconfiguration extracted to config file

22 Mar 2015

• method chaining support
• new methods: add_css() and add_js() - gives ability for adding files to existing files arrays
• added support to run library with custom array config, assigned as second parameter (during loading) $this->load->library('minify', $config);
• added support for groups in files arrays - as second (optional) parameter in methods: css(), js(), add_css() and add_js() (i.e. $this->minify->js(array('script.js'), 'extra'); - default group name is default)
• added support for strings as first parameter in methods: css(), js(), add_css() and add_js() (i.e. $this->minify->js('first.js, second.js');)
• added support for automatic files names: $config['auto_names'] = TRUE;
• external compression classes moved to minify folder
• unit tests for new features

10 Feb 2015

• Unit testing

09 Feb 2015

• 2 new engines to compres JS files
• documentation update

13 Oct 2014

• changed way of generating JS file

14 July 2014

• small bug fixes in JS compression

4 July 2014

• sample JavaScript files to see how it works
• detection of empty JS file couses force refresh

23 May 2014

• you can chose your compression engine library in config file (CSS only)
• speed optimisations
• force CSS rewrite using $this->minify->deploy_css(TRUE);

11 Mar 2014

• completly rewrite CSS parser - uses cssmin compress CSS,
• detects file modification time no longer force rewrites,
• example usage now included withing app
