Yet Another CSS Minifier

YACM is a lightweight, but effective, CSS minifier. It is slightly different from other minifiers in that it preserves the approximate vertical structure of the original CSS - so unless the formatting of the input is very unusual, the output should be just about readable., _(*1)

The code is unit-tested and can be installed using Composer., _(*2)

This code is based on a Gist of mine., _(*3)

Basic Usage

use Danbettles\Yacm\Minifier as CssMinifier;

//@todo Load the library.

$minifiedCss = CssMinifier::minifyNow('body { font-size: 1em; }');

//Or

$cssMinifier = new CssMinifier();
$minifiedCss = $cssMinifier->minify('body { font-size: 1em; }');

Use with BundleFu

You can minify the CSS bundled by BundleFu by calling YACM in a CallbackFilter filter., _(*4)

//@todo Create bundle as per Dots United's instructions.

$minifyCssFilter = new \DotsUnited\BundleFu\Filter\CallbackFilter(function($content) {
    return \Danbettles\Yacm\Minifier::minifyNow($content);
});

$bundle->setCssFilter($minifyCssFilter);

//@todo Continue using bundle as per Dots United's instructions.

If you need to add multiple CSS filters to your bundle then follow Dots United's instructions on creating and using a filter chain., _(*5)

Installation

Install using Composer., _(*6)

composer require danbettles/yacm:dev-master
