symfony2: using assetic-dump, is possible to dump just one file?

Question

After running

php app/console assetic:dump --env=prod

all the assets are dumpped.

Is there any way to dump only one file?

Answer 1

Looks like you will have to create your own command :

<?php

namespace Your\Namespace\Command;

use Symfony\Bundle\AsseticBundle\Command\AbstractCommand;

class DumpSingleAsset extends AbstractCommand
{
    protected function configure()
    {
        $this
            ->setName('assetic:dump_single_asset')
            ->setDescription('Dumps a single asset')
            ->addArgument('name', InputArgument::REQUIRED, 'The name of the asset')
        ;
    }


    protected function execute(InputInterface $input, OutputInterface $output)
    {
        $name = $input->getArgument('name');
        $this->dumpAsset($name, $output); // Inherited from AbstractCommand
    }
}

Assetic docs shows a way more simple way to dump assets, but I could not find any documentation of the AsseticBundle internals, I just read the code of the Command.

Here's a solution using only configurations. In the config file leave bundles as:

bundles: []

This will not load the assets from any bundle unless you specify it manually.

use named assets as described here to load the assets you want individually.
