CodeIgniter Minify
The goal of this project is to provide a simple way to minify and combine js and css files inside a CodeIgniter application. Currently other systems exists but I wanted the compression to be part of my build process. So on deployments I compress and minify all the js and css. Then push off to s3 but this could also be useful to write them to a single file.

Usage
Below is an overview of different usages:
Minify JS file
$this->load->driver('minify');
$file = 'test/js/test1.js';
echo $this->minify->js->min($file);
Minify CSS file
$this->load->driver('minify');
$file = 'test/css/test1.css';
echo $this->minify->css->min($file);
Minify String
$this->load->driver('minify');
$content = 'body{ padding:0; margin: 0}';
echo $this->minify->css->min($content);
Minify and combine an array of files. Useful if you need files to be in a certain order.
$this->load->driver('minify');
$files = array('test/css/test2.css', 'test/css/test1.css');
echo $this->minify->combine_files($files, [optionalParams]);
Minify and save a physical file
$this->load->driver('minify');
$file = 'test/css/test1.css';
$contents = $this->minify->css->min($file);
$this->minify->save_file($contents, 'test/css/all.css');
Minify an entire directory. The second param is an array of ignored files.
$this->load->driver('minify');
echo $this->minify->combine_directory('test/css/, array('all.css'), [optionalParams]);
Optional Params
combine_files($files, [type], [compact], [css_charset]); combine_directory($directory, [ignore], [type], [compact], [css_charset]);
Common:
[type]: string ('css' or 'js')
[compact] : bool (TRUE, FALSE). TRUE Compact/compress output, FALSE doesn't compress output (only aggregation)
[css_charset] : string (default 'utf-8'). If CSS you can force a starting single charset declaration (when aggregate files)
due to the charset pre-removal (for stantdars compliance and Webkit bugfix prevention)
set to null or leave empty if JS.
Combine dir:
[ignore] : array with files to ignore
