Small utility library that handles metadata minification and expansion.

This is used by Composer's 2.x repository metadata protocol.

Install the latest version with:

composer require composer/metadata-minifier

• PHP 5.3.2 is required but using the latest version of PHP is highly recommended.

• MetadataMinifier::expand(): Expands an array of minified versions back to their original format
• MetadataMinifier::minify(): Minifies an array of versions into a set of version diffs

For example to expand the dev versions (note the ~dev in the URL) of Monolog you would do:

$packageName = 'monolog/monolog';
$url = 'https://repo.packagist.org/p2/' . $packageName . '~dev.json';
$json = json_decode(file_get_contents($url), true);
$versions = \Composer\MetadataMinifier\MetadataMinifier::expand($json['packages'][$packageName]);
