danbettles / yacm

A gentle, but effective, CSS minifier. It is different from other minifiers in that it preserves the approximate vertical structure of the input, which means the output should be just about readable.

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.

The code is unit-tested and can be installed using Composer.

This code is based on a Gist of mine.

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.

//@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.
