Your Own Frontend http://short.ie/webfrontend

Your Own Frontend static function installPackage($package) { $config = pear2PyrusConfig::singleton(self::$autoload_registry); $config->preferred_state = 'alpha'; $p = new pear2PyrusPackage($package); try { pear2PyrusInstaller::begin(); pear2PyrusInstaller::prepare($p); pear2PyrusInstaller::commit(); } catch (Exception $e) { pear2PyrusInstaller::rollback(); echo $e; } }

Your Own Frontend class ListPackages extends ArrayIterator { function __construct($options = array()) { $packages = array(); $registry = Main::getConfig()->registry; $channel_registry = Main::getConfig()->channelregistry; foreach ($channel_registry as $channel) { Main::getConfig()->default_channel = $channel->name; foreach ($registry->package as $package) { $packages[$channel->name][] = $package->name; } } asort($packages); parent::__construct($packages); } }
