How to properly change what composer or Symfony2 does after running 'composer update/install'?

Question

There are some scripts that are executed after I run composer.

The problem is that they do things that I don't want, like php assets:install (without --symlink).

So I need to either be able to remove that, or add my own script to do php assets:install --symlink.

What would be the correct way for doing this?

EDIT

In Sensio\Bundle\DistributionBundle\Composer\ScriptHandler::installAssets() I can see an option for symlink:

if ($options['symfony-assets-install'] == 'symlink') {
    $symlink = '--symlink ';

Is that configurable somewhere?

Answer 1

To install assets with symlinks edit your composer.json (at the end) in this way

"extra": {
    "symfony-app-dir": "app",
    "symfony-web-dir": "web",
    "symfony-assets-install": "symlink"
}

Then run composer as uusal.

Answer 2

If you use composer to deploy to production environments, you may want to set the environment variable SYMFONY_ASSETS_INSTALL to symlink instead. This way production still uses hard copies which is the recommended option.
