 a lot of built-in functions, filters, tags and tests. You canlearn more about
 themfrom the `Twig Reference`_.

 Symfony addscustom extensions on top of Twig to integrate some components
 into the Twig templates. The following sections describe the custom
 :ref:`functions <reference-twig-functions>`, :ref:`filters <reference-twig-filters>`,
 :ref:`tags <reference-twig-tags>` and :ref:`tests <reference-twig-tests>`
 that are available when using the Symfony Core Framework.
 TheSymfonyframeworkaddsquite a few extra :ref:`functions <reference-twig-functions>`,
 :ref:`filters <reference-twig-filters>`, :ref:`tags <reference-twig-tags>`
 and:ref:`tests <reference-twig-tests>` to seamlessly integrate the
 various Symfony components with Twig templates. The following sections
 describe these extra features.

 There may also be tags in bundles you use that aren't listed here.
 .. tip::

    Technically, most of the extensions live in the `Twig Bridge`_. That code
    might give you some ideas when you need to write your own Twig extension
    as described in :doc:`/templating/twig_extension`.

 .. note::

    This reference only covers the Twig extensions provided by the Symfony
    framework. You are probably using some other bundles as well, and
    those might come with their own extensions not covered here.

 .. tip::

    The `Twig Extensions repository`_ contains some additional Twig extensions
    that do not belong to the Twig core, so you might want to have a look at
    the `Twig Extensions documentation`_.

 Symfony Standard Edition Extensions
 -----------------------------------

 The Symfony Standard Edition adds some bundles to the Symfony Core Framework.
 Those bundles can have other Twig extensions:

 * **Twig Extensions** includes some interesting extensions that do not belong
  to the Twig core. You can read more in `the official Twig Extensions documentation`_.
