## README

# wikimedia/minify

Minify is a PHP library for minification of JavaScript code and CSS stylesheets.

## Quick start

Install using [Composer](https://getcomposer.org/), from [Packagist.org](https://packagist.org/packages/wikimedia/minify):

```
composer require wikimedia/minify
```

## Usage

```php
use Wikimedia\Minify\JavaScriptMinifier;

$input = '
/**
 * @param a
 * @param b
 */
function sum(a, b) {
	// Add it up!
	return a + b;
}
';

$output = JavaScriptMinifier::minify( $input );
// Result:
// function sum(a,b){return a+b;}
```

```php
use Wikimedia\Minify\CSSMin;

$input = '
.foo,
.bar {
	/* comment */
	prop: value;
}
';

$output = CSSMin::minify( $input );
// Result:
// .foo,.bar{prop:value}
```

## Known limitations

The following trade-offs were made for improved runtime performance and code
simplicity. If they cause problems in real-world applications without trivial
workarounds, please let us know!

* In CSS, content within quoted strings that looks like source code is sometimes minified ([T37492](https://phabricator.wikimedia.org/T37492)).
* In CSS, writing a URL over multiple lines with escaped line-breaks is not supported ([T287631](https://phabricator.wikimedia.org/T287631)).
* In JS, certain multibyte spaces are not supported as whitespace in source code (including U+00A0 No Break Space NBSP, U+2028 Line Separator, and U+2029 Paragraph Separator) and may produce invalid output. Note that these and other Unicode multibyte characters are fully supported in strings, identifiers,  and regexes ([change 1278715](https://gerrit.wikimedia.org/r/c/mediawiki/libs/Minify/+/1278715)).
