 Debugging
 ---------

 .. versionadded:: 2.0.9
    This feature is available as of Twig ``1.5.x``, which was first shipped
    with Symfony 2.0.9.

 When using PHP, you can use ``var_dump()`` if you need to quickly find the
 value of a variable passed. This is useful, for example, inside your controller.
 The same can be achieved when using Twig by using the debug extension. This
 needs to be enabled in the config:

 .. configuration-block::

    .. code-block:: yaml

        # app/config/config.yml
        services:
            acme_hello.twig.extension.debug:
                class:        Twig_Extension_Debug
                tags:
                     - { name: 'twig.extension' }

    .. code-block:: xml

        <!-- app/config/config.xml -->
        <services>
            <service id="acme_hello.twig.extension.debug" class="Twig_Extension_Debug">
                <tag name="twig.extension" />
            </service>
        </services>

    .. code-block:: php

        // app/config/config.php
        use Symfony\Component\DependencyInjection\Definition;

        $definition = new Definition('Twig_Extension_Debug');
        $definition->addTag('twig.extension');
        $container->setDefinition('acme_hello.twig.extension.debug', $definition);
 The same can be achieved when using Twig thanks to the the debug extension.

 Template parameters can then be dumped using the ``dump`` function:
