有没有办法自动更新symfony2中的AppKernel? [英] Is there a way to update automatically the AppKernel in symfony2?
问题描述
也许类似于generate:bundle命令(在生成捆绑包后提示更新AppKernel)或Composer(后者会通过安装的依赖项更新自动加载)。
Maybe something similar to the generate:bundle command (which after generating the bundle prompts to update the AppKernel) or to Composer (which updates your autoload with the dependencies you install).
我想获得与generate:bundle类似的功能,但是与其创建一个新的包,我不想添加一个我刚刚下载的包,而无需手动编辑AppKernel。
I want to get a similar functionality to the generate:bundle, but instead of creating a new bundle I want to add a bundle I just downloaded without having to edit the AppKernel manually.
推荐答案
我找不到扩展现有命令的方法,因此我想将新的控制台命令创建到现有包中。
I couldn't find a way to EXTEND an existing command, so my thought goes to create a new console command into an existing bundle.
namespace Your\OriginalBundle\Command;
use Symfony\Bundle\FrameworkBundle\Command\ContainerAwareCommand;
use Symfony\Component\Console\Input\ArrayInput;
use Symfony\Component\Console\Input\InputArgument;
use Symfony\Component\Console\Input\InputInterface;
use Symfony\Component\Console\Input\InputOption;
use Symfony\Component\Console\Output\OutputInterface;
class AppendNewBundleCommand extends ContainerAwareCommand
{
protected $appKernel;
protected function configure()
{
$this
->setName('yourbundle:appendnewbundle')
->setDescription('Append a new bundle to the AppKernel.php')
->addArgument('namespace', InputArgument::REQUIRED, 'Define your new bundle/namespace')
;
$this->appKernel = __DIR__.'/../../../../app/AppKernel.php';
}
protected function execute(InputInterface $input, OutputInterface $output)
{
if (!file_exists($this->appKernel)) {
throw new \ErrorException(sprintf("Could not locate file %s",$this->appKernel));
}
if (!is_writable($this->appKernel)) {
throw new \ErrorException(sprintf('Cannot write into AppKernel (%s)',$this->appKernel));
}
$namespace = $input->getArgument('namespace');
$appContent = file_get_contents($this->appKernel);
$bundle = str_replace("/","\\",$namespace)."\\".str_replace("/","",$namespace);
$newBundle = "new {$bundle}(),";
$pattern = '/\$bundles\s?=\s?array\((.*?)\);/is';
preg_match($pattern, $appContent,$matches);
$bList = rtrim($matches[1],"\n ");
$e = explode(",",$bList);
$firstBundle = array_shift($e);
$tabs = substr_count($firstBundle,' ');
$newBList = "\$bundles = array("
.$bList."\n"
.str_repeat(' ', $tabs).$newBundle."\n"
.str_repeat(' ',$tabs-1).");";
file_put_contents($this->appKernel,preg_replace($pattern,$newBList,$appContent));
}
}
现在,您可以在生成包后立即执行它
You can now execute it, right after generating your bundle by doing
php app/console yourbundle:appendnewbundle Your/SecondBundle
这会将其添加到现有捆绑包列表中
This will append this to the list of existing bundles
new Your\SecondBundle\YourSecondBundle(),
如果您具有标准(symfony2)AppKernel,则此方法有效。例如:
This works if you have a standard (symfony2) AppKernel. Ex:
<?php
use Symfony\Component\HttpKernel\Kernel;
use Symfony\Component\Config\Loader\LoaderInterface;
class AppKernel extends Kernel
{
public function registerBundles()
{
$bundles = array(
new Symfony\Bundle\FrameworkBundle\FrameworkBundle(),
new Symfony\Bundle\SecurityBundle\SecurityBundle(),
new Symfony\Bundle\TwigBundle\TwigBundle(),
new Symfony\Bundle\MonologBundle\MonologBundle(),
new Symfony\Bundle\SwiftmailerBundle\SwiftmailerBundle(),
new Symfony\Bundle\DoctrineBundle\DoctrineBundle(),
new Symfony\Bundle\AsseticBundle\AsseticBundle(),
new Sensio\Bundle\FrameworkExtraBundle\SensioFrameworkExtraBundle(),
new JMS\SecurityExtraBundle\JMSSecurityExtraBundle(),
new Ornicar\ApcBundle\OrnicarApcBundle(),
new Your\OriginalBundle\YourOriginalBundle(),
);
if (in_array($this->getEnvironment(), array('dev', 'test'))) {
$bundles[] = new Symfony\Bundle\WebProfilerBundle\WebProfilerBundle();
$bundles[] = new Sensio\Bundle\DistributionBundle\SensioDistributionBundle();
$bundles[] = new Sensio\Bundle\GeneratorBundle\SensioGeneratorBundle();
}
return $bundles;
}
public function registerContainerConfiguration(LoaderInterface $loader)
{
$loader->load(__DIR__.'/config/config_'.$this->getEnvironment().'.yml');
}
}
