+ *
+ * In this example, if you try to use a class in the Symfony\Component
+ * namespace or one of its children (Symfony\Component\Console for instance),
+ * the autoloader will first look for the class under the component/
+ * directory, and it will then fallback to the framework/ directory if not
+ * found before giving up.
+ *
+ * This class is loosely based on the Symfony UniversalClassLoader.

+EventDispatcher Component
+=========================
+
+EventDispatcher implements a lightweight version of the Observer design
+pattern.
+
+    use Symfony\Component\EventDispatcher\EventDispatcher;
+    use Symfony\Component\EventDispatcher\Event;
+
+    $dispatcher = new EventDispatcher();
+
+    $dispatcher->addListener('event_name', function (Event $event) {
+        // ...
+    });
+
+    $dispatcher->dispatch('event_name');
+
+Resources
+---------
+
+You can run the unit tests with the following command:
+
+    $ cd path/to/Symfony/Component/EventDispatcher/
+    $ composer.phar install --dev
+    $ phpunit

+Filesystem Component
+====================
+
+Filesystem provides basic utility to manipulate the file system:
+
+```php
+<?php
+
+use Symfony\Component\Filesystem\Filesystem;
+
+$filesystem = new Filesystem();
+
+$filesystem->copy($originFile, $targetFile, $override = false);
+
+$filesystem->mkdir($dirs, $mode = 0777);
+
+$filesystem->touch($files, $time = null, $atime = null);
+
+$filesystem->remove($files);
+
+$filesystem->chmod($files, $mode, $umask = 0000, $recursive = false);
+
+$filesystem->chown($files, $user, $recursive = false);
+
+$filesystem->chgrp($files, $group, $recursive = false);
+
+$filesystem->rename($origin, $target);
+
+$filesystem->symlink($originDir, $targetDir, $copyOnWindows = false);
+
+$filesystem->makePathRelative($endPath, $startPath);
+
+$filesystem->mirror($originDir, $targetDir, \Traversable $iterator = null, $options = array());
+
+$filesystem->isAbsolutePath($file);
+```
+
+Resources
+---------

+CHANGELOG
+=========
+
+
+2.3.0
+------
+
+ * deprecated FormPerformanceTestCase and FormIntegrationTestCase in the Symfony\Component\Form\Tests namespace and moved them to the Symfony\Component\Form\Test namespace
+ * deprecated TypeTestCase in the Symfony\Component\Form\Tests\Extension\Core\Type namespace and moved it to the Symfony\Component\Form\Test namespace
+ * changed FormRenderer::humanize() to humanize also camel cased field name
+ * added RequestHandlerInterface and FormInterface::handleRequest()
+ * deprecated passing a Request instance to FormInterface::bind()
+ * added options "method" and "action" to FormType
+ * deprecated option "virtual" in favor "inherit_data"
+ * deprecated VirtualFormAwareIterator in favor of InheritDataAwareIterator
+ * [BC BREAK] removed the "array" type hint from DataMapperInterface
+ * improved forms inheriting their parent data to actually return that data from getData(), getNormData() and getViewData()
+ * added component-level exceptions for various SPL exceptions
+   changed all uses of the deprecated Exception class to use more specialized exceptions instead
+   removed NotInitializedException, NotValidException, TypeDefinitionException, TypeLoaderException, CreationException
+ * added events PRE_SUBMIT, SUBMIT and POST_SUBMIT
+ * deprecated events PRE_BIND, BIND and POST_BIND
+ * [BC BREAK] renamed bind() and isBound() in FormInterface to submit() and isSubmitted()
+ * added methods submit() and isSubmitted() to Form
+ * deprecated bind() and isBound() in Form
+ * deprecated AlreadyBoundException in favor of AlreadySubmittedException
+ * added support for PATCH requests
+ * [BC BREAK] added initialize() to FormInterface
+ * [BC BREAK] added getAutoInitialize() to FormConfigInterface
+ * [BC BREAK] added setAutoInitialize() to FormConfigBuilderInterface
+ * [BC BREAK] initialization for Form instances added to a form tree must be manually disabled
+ * PRE_SET_DATA is now guaranteed to be called after children were added by the form builder,
+   unless FormInterface::setData() is called manually
+ * fixed CSRF error message to be translated
+ * custom CSRF error messages can now be set through the "csrf_message" option
+ * fixed: expanded single-choice fields now show a radio button for the empty value
+
+2.2.0
+-----
+
+ * TrimListener now removes unicode whitespaces
+ * deprecated getParent(), setParent() and hasParent() in FormBuilderInterface
+ * FormInterface::add() now accepts a FormInterface instance OR a field's name, type and options
+ * removed special characters between the choice or text fields of DateType unless
+   the option "format" is set to a custom value
+ * deprecated FormException and introduced ExceptionInterface instead
+ * [BC BREAK] FormException is now an interface
+ * protected FormBuilder methods from being called when it is turned into a FormConfigInterface with getFormConfig()
+ * [BC BREAK] inserted argument `$message` in the constructor of `FormError`
+ * the PropertyPath class and related classes were moved to a dedicated
+   PropertyAccess component. During the move, InvalidPropertyException was
+   renamed to NoSuchPropertyException. FormUtil was split: FormUtil::singularify()
+   can now be found in Symfony\Component\PropertyAccess\StringUtil. The methods
+   getValue() and setValue() from PropertyPath were extracted into a new class
+   PropertyAccessor.
+ * added an optional PropertyAccessorInterface parameter to FormType,
+   ObjectChoiceList and PropertyPathMapper
+ * [BC BREAK] PropertyPathMapper and FormType now have a constructor
+ * [BC BREAK] setting the option "validation_groups" to ``false`` now disables validation
+   instead of assuming group "Default"
+
+2.1.0
+-----
+
+ * [BC BREAK] ``read_only`` field attribute now renders as ``readonly="readonly"``, use ``disabled`` instead
+ * [BC BREAK] child forms now aren't validated anymore by default
+ * made validation of form children configurable (new option: cascade_validation)
+ * added support for validation groups as callbacks
+ * made the translation catalogue configurable via the "translation_domain" option
+ * added Form::getErrorsAsString() to help debugging forms
+ * allowed setting different options for RepeatedType fields (like the label)
+ * added support for empty form name at root level, this enables rendering forms
+   without form name prefix in field names
+ * [BC BREAK] form and field names must start with a letter, digit or underscore
+   and only contain letters, digits, underscores, hyphens and colons
+ * [BC BREAK] changed default name of the prototype in the "collection" type
+   from "$$name$$" to "\__name\__". No dollars are appended/prepended to custom
+   names anymore.
+ * [BC BREAK] improved ChoiceListInterface
+ * [BC BREAK] added SimpleChoiceList and LazyChoiceList as replacement of
+   ArrayChoiceList
+ * added ChoiceList and ObjectChoiceList to use objects as choices
+ * [BC BREAK] removed EntitiesToArrayTransformer and EntityToIdTransformer.
+   The former has been replaced by CollectionToArrayTransformer in combination
+   with EntityChoiceList, the latter is not required in the core anymore.
+ * [BC BREAK] renamed
+   * ArrayToBooleanChoicesTransformer to ChoicesToBooleanArrayTransformer
+   * ScalarToBooleanChoicesTransformer to ChoiceToBooleanArrayTransformer
+   * ArrayToChoicesTransformer to ChoicesToValuesTransformer
+   * ScalarToChoiceTransformer to ChoiceToValueTransformer
+   to be consistent with the naming in ChoiceListInterface.
+   They were merged into ChoiceList and have no public equivalent anymore.
+ * choice fields now throw a FormException if neither the "choices" nor the
+   "choice_list" option is set
+ * the radio type is now a child of the checkbox type
+ * the collection, choice (with multiple selection) and entity (with multiple
+   selection) types now make use of addXxx() and removeXxx() methods in your
+   model if you set "by_reference" to false. For a custom, non-recognized
+   singular form, set the "property_path" option like this: "plural|singular"
+ * forms now don't create an empty object anymore if they are completely
+   empty and not required. The empty value for such forms is null.
+ * added constant Guess::VERY_HIGH_CONFIDENCE
+ * [BC BREAK] The methods `add`, `remove`, `setParent`, `bind` and `setData`
+   in class Form now throw an exception if the form is already bound
+ * fields of constrained classes without a NotBlank or NotNull constraint are
+   set to not required now, as stated in the docs
+ * fixed TimeType and DateTimeType to not display seconds when "widget" is
+   "single_text" unless "with_seconds" is set to true
+ * checkboxes of in an expanded multiple-choice field don't include the choice
+   in their name anymore. Their names terminate with "[]" now.
+ * deprecated FormValidatorInterface and substituted its implementations
+   by event subscribers
+ * simplified CSRF protection and removed the csrf type
+ * deprecated FieldType and merged it into FormType
+ * added new option "compound" that lets you switch between field and form behavior
+ * [BC BREAK] renamed theme blocks
+   * "field_*" to "form_*"
+   * "field_widget" to "form_widget_simple"
+   * "widget_choice_options" to "choice_widget_options"
+   * "generic_label" to "form_label"
+ * added theme blocks "form_widget_compound", "choice_widget_expanded" and
+   "choice_widget_collapsed" to make theming more modular
+ * ValidatorTypeGuesser now guesses "collection" for array type constraint
+ * added method `guessPattern` to FormTypeGuesserInterface to guess which pattern to use in the HTML5 attribute "pattern"
+ * deprecated method `guessMinLength` in favor of `guessPattern`
+ * labels don't display field attributes anymore. Label attributes can be
+   passed in the "label_attr" option/variable
+ * added option "mapped" which should be used instead of setting "property_path" to false
+ * [BC BREAK] "data_class" now *must* be set if a form maps to an object and should be left empty otherwise
+ * improved error mapping on forms
+   * dot (".") rules are now allowed to map errors assigned to a form to
+     one of its children
+ * errors are not mapped to unsynchronized forms anymore
+ * [BC BREAK] changed Form constructor to accept a single `FormConfigInterface` object
+ * [BC BREAK] changed argument order in the FormBuilder constructor
+ * added Form method `getViewData`
+ * deprecated Form methods
+   * `getTypes`
+   * `getErrorBubbling`
+   * `getNormTransformers`
+   * `getClientTransformers`
+   * `getAttribute`
+   * `hasAttribute`
+   * `getClientData`

+   * `prependClientTransformer`
+   * `appendClientTransformer`
+   * `getClientTransformers`
+   * `resetClientTransformers`
+   * `prependNormTransformer`
+   * `appendNormTransformer`
+   * `getNormTransformers`
+   * `resetNormTransformers`
+ * deprecated the option "validation_constraint" in favor of the new
+   option "constraints"
+ * removed superfluous methods from DataMapperInterface
+   * `mapFormToData`
+   * `mapDataToForm`
+ * added `setDefaultOptions` to FormTypeInterface and FormTypeExtensionInterface
+   which accepts an OptionsResolverInterface instance
+ * deprecated the methods `getDefaultOptions` and `getAllowedOptionValues`
+   in FormTypeInterface and FormTypeExtensionInterface

+/**
+ * Form represents a form.
+ *
+ * To implement your own form fields, you need to have a thorough understanding
+ * of the data flow within a form. A form stores its data in three different
+ * representations:
+ *
+ *   (1) the "model" format required by the form's object
+ *   (2) the "normalized" format for internal processing
+ *   (3) the "view" format used for display
+ *
+ * A date field, for example, may store a date as "Y-m-d" string (1) in the
+ * object. To facilitate processing in the field, this value is normalized
+ * to a DateTime object (2). In the HTML representation of your form, a
+ * localized string (3) is presented to and modified by the user.
+ *
+ * In most cases, format (1) and format (2) will be the same. For example,
+ * a checkbox field uses a Boolean value for both internal processing and
+ * storage in the object. In these cases you simply need to set a value
+ * transformer to convert between formats (2) and (3). You can do this by
+ * calling addViewTransformer().
+ *
+ * In some cases though it makes sense to make format (1) configurable. To
+ * demonstrate this, let's extend our above date field to store the value
+ * either as "Y-m-d" string or as timestamp. Internally we still want to
+ * use a DateTime object for processing. To convert the data from string/integer
+ * to DateTime you can set a normalization transformer by calling
+ * addNormTransformer(). The normalized data is then converted to the displayed
+ * data as described before.
+ *
+ * The conversions (1) -> (2) -> (3) use the transform methods of the transformers.
+ * The conversions (3) -> (2) -> (1) use the reverseTransform methods of the transformers.

+ * Entry point of the Form component.
+ *
+ * Use this class to conveniently create new form factories:
+ *
+ * <code>
+ * use Symfony\Component\Form\Forms;
+ *
+ * $formFactory = Forms::createFormFactory();
+ *
+ * $form = $formFactory->createBuilder()
+ *     ->add('firstName', 'text')
+ *     ->add('lastName', 'text')
+ *     ->add('age', 'integer')
+ *     ->add('gender', 'choice', array(
+ *         'choices' => array('m' => 'Male', 'f' => 'Female'),
+ *     ))
+ *     ->getForm();
+ * </code>
+ *
+ * You can also add custom extensions to the form factory:
+ *
+ * <code>
+ * $formFactory = Forms::createFormFactoryBuilder()
+ *     ->addExtension(new AcmeExtension())
+ *     ->getFormFactory();
+ * </code>
+ *
+ * If you create custom form types or type extensions, it is
+ * generally recommended to create your own extensions that lazily
+ * load these types and type extensions. In projects where performance
+ * does not matter that much, you can also pass them directly to the
+ * form factory:
+ *
+ * <code>
+ * $formFactory = Forms::createFormFactoryBuilder()
+ *     ->addType(new PersonType())
+ *     ->addType(new PhoneNumberType())
+ *     ->addTypeExtension(new FormTypeHelpTextExtension())
+ *     ->getFormFactory();
+ * </code>
+ *
+ * Support for CSRF protection is provided by the CsrfExtension.
+ * This extension needs a CSRF provider with a strong secret
+ * (e.g. a 20 character long random string). The default
+ * implementation for this is DefaultCsrfProvider:
+ *
+ * <code>
+ * use Symfony\Component\Form\Extension\Csrf\CsrfExtension;
+ * use Symfony\Component\Form\Extension\Csrf\CsrfProvider\DefaultCsrfProvider;
+ *
+ * $secret = 'V8a5Z97e...';
+ * $formFactory = Forms::createFormFactoryBuilder()
+ *     ->addExtension(new CsrfExtension(new DefaultCsrfProvider($secret)))
+ *     ->getFormFactory();
+ * </code>
+ *
+ * Support for the HttpFoundation is provided by the
+ * HttpFoundationExtension. You are also advised to load the CSRF
+ * extension with the driver for HttpFoundation's Session class:
+ *
+ * <code>
+ * use Symfony\Component\HttpFoundation\Session\Session;
+ * use Symfony\Component\Form\Extension\HttpFoundation\HttpFoundationExtension;
+ * use Symfony\Component\Form\Extension\Csrf\CsrfExtension;
+ * use Symfony\Component\Form\Extension\Csrf\CsrfProvider\SessionCsrfProvider;
+ *
+ * $session = new Session();
+ * $secret = 'V8a5Z97e...';
+ * $formFactory = Forms::createFormFactoryBuilder()
+ *     ->addExtension(new HttpFoundationExtension())
+ *     ->addExtension(new CsrfExtension(new SessionCsrfProvider($session, $secret)))
+ *     ->getFormFactory();
+ * </code>
+ *
+ * Support for the Validator component is provided by ValidatorExtension.
+ * This extension needs a validator object to function properly:
+ *
+ * <code>
+ * use Symfony\Component\Validator\Validation;
+ * use Symfony\Component\Form\Extension\Validator\ValidatorExtension;
+ *
+ * $validator = Validation::createValidator();
+ * $formFactory = Forms::createFormFactoryBuilder()
+ *     ->addExtension(new ValidatorExtension($validator))
+ *     ->getFormFactory();
+ * </code>
+ *
+ * Support for the Templating component is provided by TemplatingExtension.
+ * This extension needs a PhpEngine object for rendering forms. As second
+ * argument you should pass the names of the default themes. Here is an
+ * example for using the default layout with "<div>" tags:
+ *
+ * <code>
+ * use Symfony\Component\Form\Extension\Templating\TemplatingExtension;
+ *
+ * $formFactory = Forms::createFormFactoryBuilder()
+ *     ->addExtension(new TemplatingExtension($engine, null, array(
+ *         'FrameworkBundle:Form',
+ *     )))
+ *     ->getFormFactory();
+ * </code>
+ *
+ * The next example shows how to include the "<table>" layout:
+ *
+ * <code>
+ * use Symfony\Component\Form\Extension\Templating\TemplatingExtension;
+ *
+ * $formFactory = Forms::createFormFactoryBuilder()
+ *     ->addExtension(new TemplatingExtension($engine, null, array(
+ *         'FrameworkBundle:Form',
+ *         'FrameworkBundle:FormTable',
+ *     )))
+ *     ->getFormFactory();
+ * </code>
+ *
+ * If you also loaded the CsrfExtension, you should pass the CSRF provider
+ * to the extension so that you can render CSRF tokens in your templates
+ * more easily:
+ *
+ * <code>
+ * use Symfony\Component\Form\Extension\Csrf\CsrfExtension;
+ * use Symfony\Component\Form\Extension\Csrf\CsrfProvider\DefaultCsrfProvider;
+ * use Symfony\Component\Form\Extension\Templating\TemplatingExtension;
+ *
+ *
+ * $secret = 'V8a5Z97e...';
+ * $csrfProvider = new DefaultCsrfProvider($secret);
+ * $formFactory = Forms::createFormFactoryBuilder()

+Contributing to the Intl component
+==================================
+
+A very good way of contributing to the Intl component is by updating the
+included data for the ICU version you have installed on your system.
+
+Preparation
+-----------
+
+To prepare, you need to install the development dependencies of the component.
+
+    $ cd /path/to/Symfony/Component/Intl
+    $ composer.phar install --dev
+
+Determining your ICU version
+---------------------------
+
+The ICU version installed in your PHP environment can be found by running
+icu-version.php:
+
+    $ php Resources/bin/icu-version.php
+
+Updating the ICU data
+---------------------
+
+To update the data files, run the update-icu-component.php script:
+
+    $ php Resources/bin/update-icu-component.php
+
+The script needs the binaries "svn" and "make" to be available on your system.
+It will download the latest version of the ICU sources for the ICU version
+installed in your PHP environment. The script will then compile the "genrb"
+binary and use it to compile the ICU data files to binaries. The binaries are
+copied to the Resources/ directory of the Icu component found in the
+vendor/symfony/icu/ directory.
+
+Updating the stub data
+----------------------
+
+In the previous step you updated the Icu component for the ICU version
+installed on your system. If you are using the latest ICU version, you should
+also create the stub data files which will be used by people who don't have
+the intl extension installed.
+
+To update the stub files, run the update-stubs.php script:
+
+    $ php Resources/bin/update-stubs.php
+
+The script will fail if you don't have the latest ICU version. If you want to
+upgrade the ICU version, adjust the return value of the
+`Intl::getIcuStubVersion()` before you run the script.
+
+The script creates copies of the binary resource bundles in the Icu component
+and stores them in the Resources/ directory of the Intl component. The copies
+are made for the locale "en" only and are stored in .php files, so that they
+can be read even if the intl extension is not available.
+
+Creating a pull request
+-----------------------
+
+You need to create up to two pull requests:
+
+* If you updated the Icu component, you need to push that change and create a
+  pull request in the `symfony/Icu` repository. Make sure to submit the pull
+  request to the correct master branch. If you updated the ICU data for version
+  4.8, your pull request goes to branch `48-master`, for version 49 to
+  `49-master` and so on.
+
+* If you updated the stub files of the Intl component, you need to push that
+  change and create a pull request in the `symfony/symfony` repository. The
+  pull request should be based on the `master` branch.
+
+Combining .res files to a .dat-package
+--------------------------------------
+
+The individual *.res files can be combined into a single .dat-file.
+Unfortunately, PHP's `ResourceBundle` class is currently not able to handle
+.dat-files.
+
+Once it is, the following steps have to be followed to build the .dat-file:
+
+1. Package the resource bundles into a single file
+
+   $ find . -name *.res | sed -e "s/\.\///g" > packagelist.txt
+   $ pkgdata -p region -T build -d . packagelist.txt
+
+2. Clean up
+
+   $ rm -rf build packagelist.txt
+
+3. You can now move region.dat to replace the version bundled with Symfony2.

+Intl Component
+=============
+
+A PHP replacement layer for the C intl extension that includes additional data
+from the ICU library.
+
+The replacement layer is limited to the locale "en". If you want to use other
+locales, you should [install the intl extension] [1] instead.
+
+Documentation
+-------------
+
+The documentation for the component can be found [online] [2].
+
+Resources
+---------
+
+You can run the unit tests with the following command:
+
+    $ cd path/to/Symfony/Component/Intl/
+    $ composer.phar install --dev
+    $ phpunit
+
+[0]: http://www.php.net/manual/en/intl.setup.php

+OptionsResolver Component
+=========================
+
+OptionsResolver helps at configuring objects with option arrays.
+
+It supports default values on different levels of your class hierarchy,
+option constraints (required vs. optional, allowed values) and lazy options
+whose default value depends on the value of another option.
+
+The following example demonstrates a Person class with two required options
+"firstName" and "lastName" and two optional options "age" and "gender", where
+the default value of "gender" is derived from the passed first name, if
+possible, and may only be one of "male" and "female".
+
+    use Symfony\Component\OptionsResolver\OptionsResolver;
+    use Symfony\Component\OptionsResolver\OptionsResolverInterface;
+    use Symfony\Component\OptionsResolver\Options;
+
+    class Person
+    {
+        protected $options;
+
+        public function __construct(array $options = array())
+        {
+            $resolver = new OptionsResolver();
+            $this->setDefaultOptions($resolver);
+
+            $this->options = $resolver->resolve($options);
+        }
+
+        protected function setDefaultOptions(OptionsResolverInterface $resolver)
+        {
+            $resolver->setRequired(array(
+                'firstName',
+                'lastName',
+            ));
+
+            $resolver->setDefaults(array(
+                'age' => null,
+                'gender' => function (Options $options) {
+                    if (self::isKnownMaleName($options['firstName'])) {
+                        return 'male';
+                    }
+
+                    return 'female';
+                },
+            ));
+
+            $resolver->setAllowedValues(array(
+                'gender' => array('male', 'female'),
+            ));
+        }
+    }
+
+We can now easily instantiate a Person object:
+
+    // 'gender' is implicitly set to 'female'
+    $person = new Person(array(
+        'firstName' => 'Jane',
+        'lastName' => 'Doe',
+    ));
+
+We can also override the default values of the optional options:
+
+    $person = new Person(array(
+        'firstName' => 'Abdullah',
+        'lastName' => 'Mogashi',
+        'gender' => 'male',
+        'age' => 30,
+    ));
+
+Options can be added or changed in subclasses by overriding the `setDefaultOptions`
+method:
+
+    use Symfony\Component\OptionsResolver\OptionsResolver;
+    use Symfony\Component\OptionsResolver\Options;
+
+    class Employee extends Person
+    {
+        protected function setDefaultOptions(OptionsResolverInterface $resolver)
+        {
+            parent::setDefaultOptions($resolver);
+
+            $resolver->setRequired(array(
+                'birthDate',
+            ));
+
+            $resolver->setDefaults(array(
+                // $previousValue contains the default value configured in the
+                // parent class
+                'age' => function (Options $options, $previousValue) {
+                    return self::calculateAge($options['birthDate']);
+                }
+            ));
+        }
+    }
+
+

+CHANGELOG
+=========
+
+2.3.0
+------
+
+ * added PropertyAccessorBuilder, to enable or disable the support of "__call"
+ * added support for "__call" in the PropertyAccessor (disabled by default)
+ * [BC BREAK] changed PropertyAccessor to continue its search for a property or
+   method even if a non-public match was found. Before, a PropertyAccessDeniedException
+   was thrown in this case. Class PropertyAccessDeniedException was removed
+   now.
+ * deprecated PropertyAccess::getPropertyAccessor
+ * added PropertyAccess::createPropertyAccessor and PropertyAccess::createPropertyAccessorBuilder

+CHANGELOG
+=========
+
+2.3.0
+-----
+
+ * added RequestContext::getQueryString()
+
+2.2.0
+-----
+
+ * [DEPRECATION] Several route settings have been renamed (the old ones will be removed in 3.0):
+
+    * The `pattern` setting for a route has been deprecated in favor of `path`
+    * The `_scheme` and `_method` requirements have been moved to the `schemes` and `methods` settings
+
+   Before:
+
+   ```
+   article_edit:
+       pattern: /article/{id}
+       requirements: { '_method': 'POST|PUT', '_scheme': 'https', 'id': '\d+' }
+
+   <route id="article_edit" pattern="/article/{id}">
+       <requirement key="_method">POST|PUT</requirement>
+       <requirement key="_scheme">https</requirement>
+       <requirement key="id">\d+</requirement>
+   </route>
+
+   $route = new Route();
+   $route->setPattern('/article/{id}');
+   $route->setRequirement('_method', 'POST|PUT');
+   $route->setRequirement('_scheme', 'https');
+   ```
+
+   After:
+
+   ```
+   article_edit:
+       path: /article/{id}
+       methods: [POST, PUT]
+       schemes: https
+       requirements: { 'id': '\d+' }
+
+   <route id="article_edit" pattern="/article/{id}" methods="POST PUT" schemes="https">
+       <requirement key="id">\d+</requirement>
+   </route>
+
+   $route = new Route();
+   $route->setPath('/article/{id}');
+   $route->setMethods(array('POST', 'PUT'));
+   $route->setSchemes('https');
+   ```
+
+ * [BC BREAK] RouteCollection does not behave like a tree structure anymore but as
+   a flat array of Routes. So when using PHP to build the RouteCollection, you must
+   make sure to add routes to the sub-collection before adding it to the parent
+   collection (this is not relevant when using YAML or XML for Route definitions).
+
+   Before:
+
+   ```
+   $rootCollection = new RouteCollection();
+   $subCollection = new RouteCollection();
+   $rootCollection->addCollection($subCollection);
+   $subCollection->add('foo', new Route('/foo'));
+   ```
+
+   After:
+
+   ```
+   $rootCollection = new RouteCollection();
+   $subCollection = new RouteCollection();
+   $subCollection->add('foo', new Route('/foo'));
+   $rootCollection->addCollection($subCollection);
+   ```
+
+   Also one must call `addCollection` from the bottom to the top hierarchy.
+   So the correct sequence is the following (and not the reverse):
+
+   ```
+   $childCollection->->addCollection($grandchildCollection);
+   $rootCollection->addCollection($childCollection);
+   ```
+
+ * [DEPRECATION] The methods `RouteCollection::getParent()` and `RouteCollection::getRoot()`
+   have been deprecated and will be removed in Symfony 2.3.
+ * [BC BREAK] Misusing the `RouteCollection::addPrefix` method to add defaults, requirements
+   or options without adding a prefix is not supported anymore. So if you called `addPrefix`
+   with an empty prefix or `/` only (both have no relevance), like
+   `addPrefix('', $defaultsArray, $requirementsArray, $optionsArray)`
+   you need to use the new dedicated methods `addDefaults($defaultsArray)`,
+   `addRequirements($requirementsArray)` or `addOptions($optionsArray)` instead.
+ * [DEPRECATION] The `$options` parameter to `RouteCollection::addPrefix()` has been deprecated
+   because adding options has nothing to do with adding a path prefix. If you want to add options
+   to all child routes of a RouteCollection, you can use `addOptions()`.
+ * [DEPRECATION] The method `RouteCollection::getPrefix()` has been deprecated
+   because it suggested that all routes in the collection would have this prefix, which is
+   not necessarily true. On top of that, since there is no tree structure anymore, this method
+   is also useless. Don't worry about performance, prefix optimization for matching is still done
+   in the dumper, which was also improved in 2.2.0 to find even more grouping possibilities.
+ * [DEPRECATION] `RouteCollection::addCollection(RouteCollection $collection)` should now only be
+   used with a single parameter. The other params `$prefix`, `$default`, `$requirements` and `$options`
+   will still work, but have been deprecated. The `addPrefix` method should be used for this
+   use-case instead.
+   Before: `$parentCollection->addCollection($collection, '/prefix', array(...), array(...))`
+   After:
+   ```
+   $collection->addPrefix('/prefix', array(...), array(...));
+   $parentCollection->addCollection($collection);
+   ```
+ * added support for the method default argument values when defining a @Route
+ * Adjacent placeholders without separator work now, e.g. `/{x}{y}{z}.{_format}`.
+ * Characters that function as separator between placeholders are now whitelisted
+   to fix routes with normal text around a variable, e.g. `/prefix{var}suffix`.
+ * [BC BREAK] The default requirement of a variable has been changed slightly.
+   Previously it disallowed the previous and the next char around a variable. Now
+   it disallows the slash (`/`) and the next char. Using the previous char added
+   no value and was problematic because the route `/index.{_format}` would be
+   matched by `/index.ht/ml`.
+ * The default requirement now uses possessive quantifiers when possible which
+   improves matching performance by up to 20% because it prevents backtracking
+   when it's not needed.
+ * The ConfigurableRequirementsInterface can now also be used to disable the requirements
+   check on URL generation completely by calling `setStrictRequirements(null)`. It
+   improves performance in production environment as you should know that params always
+   pass the requirements (otherwise it would break your link anyway).
+ * There is no restriction on the route name anymore. So non-alphanumeric characters
+   are now also allowed.
+ * [BC BREAK] `RouteCompilerInterface::compile(Route $route)` was made static
+   (only relevant if you implemented your own RouteCompiler).
+ * Added possibility to generate relative paths and network paths in the UrlGenerator, e.g.
+   "../parent-file" and "//example.com/dir/file". The third parameter in
+   `UrlGeneratorInterface::generate($name, $parameters = array(), $referenceType = self::ABSOLUTE_PATH)`
+   now accepts more values and you should use the constants defined in `UrlGeneratorInterface` for
+   claritiy. The old method calls with a Boolean parameter will continue to work because they
+   equal the signature using the constants.
+
+2.1.0
+-----
+
+ * added RequestMatcherInterface
+ * added RequestContext::fromRequest()
+ * the UrlMatcher does not throw a \LogicException anymore when the required
+   scheme is not the current one
+ * added TraceableUrlMatcher
+ * added the possibility to define options, default values and requirements
+   for placeholders in prefix, including imported routes
+ * added RouterInterface::getRouteCollection
+ * [BC BREAK] the UrlMatcher urldecodes the route parameters only once, they
+   were decoded twice before. Note that the `urldecode()` calls have been
+   changed for a single `rawurldecode()` in order to support `+` for input
+   paths.
+ * added RouteCollection::getRoot method to retrieve the root of a
+   RouteCollection tree
+ * [BC BREAK] made RouteCollection::setParent private which could not have
+   been used anyway without creating inconsistencies
+ * [BC BREAK] RouteCollection::remove also removes a route from parent
+   collections (not only from its children)
+ * added ConfigurableRequirementsInterface that allows to disable exceptions 
+   (and generate empty URLs instead) when generating a route with an invalid
+   parameter value

+ * ConfigurableRequirementsInterface must be implemented by URL generators that

+ * do not match the requirements. It is also possible to disable the requirements
+ * check for URL generation completely.
+ *
+ * The possible configurations and use-cases:
+ * - setStrictRequirements(true): Throw an exception for mismatching requirements. This
+ *   is mostly useful in development environment.
+ * - setStrictRequirements(false): Don't throw an exception but return null as URL for
+ *   mismatching requirements and log the problem. Useful when you cannot control all
+ *   params because they come from third party libs but don't want to have a 404 in
+ *   production environment. It should log the mismatch so one can review it.
+ * - setStrictRequirements(null): Return the URL with the given parameters without
+ *   checking the requirements at all. When generating an URL you should either trust
+ *   your params or you validated them beforehand because otherwise it would break your
+ *   link anyway. So in production environment you should know that params always pass
+ *   the requirements. Thus this option allows to disable the check on URL generation for
+ *   performance reasons (saving a preg_match for each requirement every time a URL is
+ *   generated).

+ * AnnotationClassLoader loads routing information from a PHP class and its methods.
+ *
+ * You need to define an implementation for the getRouteDefaults() method. Most of the
+ * time, this method should define some PHP callable to be called for the route
+ * (a controller in MVC speak).
+ *
+ * The @Route annotation can be set on the class (for global parameters),
+ * and on each method.
+ *
+ * The @Route annotation main value is the route path. The annotation also
+ * recognizes several parameters: requirements, options, defaults, schemes,
+ * methods, host, and name. The name parameter is mandatory.
+ * Here is an example of how you should be able to use it:
+ *
+ *     /**

+ *      * /
+ *     class Blog

+Routing Component
+=================
+
+Routing associates a request with the code that will convert it to a response.
+
+The example below demonstrates how you can set up a fully working routing
+system:
+
+    use Symfony\Component\HttpFoundation\Request;
+    use Symfony\Component\Routing\Matcher\UrlMatcher;
+    use Symfony\Component\Routing\RequestContext;
+    use Symfony\Component\Routing\RouteCollection;
+    use Symfony\Component\Routing\Route;
+
+    $routes = new RouteCollection();
+    $routes->add('hello', new Route('/hello', array('controller' => 'foo')));
+
+    $context = new RequestContext();
+
+    // this is optional and can be done without a Request instance
+    $context->fromRequest(Request::createFromGlobals());
+
+    $matcher = new UrlMatcher($routes, $context);
+
+    $parameters = $matcher->match('/hello');
+
+Resources
+---------
+
+You can run the unit tests with the following command:
+
+    $ cd path/to/Symfony/Component/Routing/
+    $ composer.phar install --dev
+    $ phpunit

+CHANGELOG
+=========
+
+2.3.0
+-----
+
+ * added classes to make operations on catalogues (like making a diff or a merge on 2 catalogues)
+ * added Translator::getFallbackLocales()
+ * deprecated Translator::setFallbackLocale() in favor of the new Translator::setFallbackLocales() method
+
+2.2.0
+-----
+
+ * QtTranslationsLoader class renamed to QtFileLoader. QtTranslationsLoader is deprecated and will be removed in 2.3.
+ * [BC BREAK] uniformized the exception thrown by the load() method when an error occurs. The load() method now
+   throws Symfony\Component\Translation\Exception\NotFoundResourceException when a resource cannot be found
+   and Symfony\Component\Translation\Exception\InvalidResourceException when a resource is invalid.
+ * changed the exception class thrown by some load() methods from \RuntimeException to \InvalidArgumentException
+   (IcuDatFileLoader, IcuResFileLoader and QtFileLoader)
+
+2.1.0
+-----
+
+ * added support for more than one fallback locale
+ * added support for extracting translation messages from templates (Twig and PHP)
+ * added dumpers for translation catalogs
+ * added support for QT, gettext, and ResourceBundles

+=====================
+
+Translation provides tools for loading translation files and generating
+translated strings from these including support for pluralization.

+    $translator->setFallbackLocales(array('fr'));
+    $translator->addLoader('array', new ArrayLoader());
+    $translator->addResource('array', array(
+        'Hello World!' => 'Bonjour',

+CHANGELOG
+=========
+
+2.3.0
+-----
+
+ * added helpers form(), form_start() and form_end()
+ * deprecated form_enctype() in favor of form_start()
+
+2.2.0
+-----
+
+ * added a `controller` function to help generating controller references
+ * added a `render_esi` and a `render_hinclude` function
+ * [BC BREAK] restricted the `render` tag to only accept URIs or ControllerReference instances (the signature changed)
+ * added a `render` function to render a request
+ * The `app` global variable is now injected even when using the twig service directly.
+ * Added an optional parameter to the `path` and `url` function which allows to generate
+   relative paths (e.g. "../parent-file") and scheme-relative URLs (e.g. "//example.com/dir/file").
+
+2.1.0
+-----
+
+ * added global variables access in a form theme
+ * added TwigEngine
+ * added TwigExtractor
+ * added a csrf_token function
+ * added a way to specify a default domain for a Twig template (via the
+   'trans_default_domain' tag)

+ * fixed Template::getAttribute() as properties in PHP are case sensitive
+ * removed coupling between Twig_Node and Twig_Template
+ * fixed the ternary operator precedence rule
+
+* 1.0.0-RC1 (2011-01-09)
+
+Backward incompatibilities:
+
+ * the "items" filter, which has been deprecated for quite a long time now, has been removed
+ * the "range" filter has been converted to a function: 0|range(10) -> range(0, 10)
+ * the "constant" filter has been converted to a function: {{ some_date|date('DATE_W3C'|constant) }} -> {{ some_date|date(constant('DATE_W3C')) }}
+ * the "cycle" filter has been converted to a function: {{ ['odd', 'even']|cycle(i) }} -> {{ cycle(['odd', 'even'], i) }}
+ * the "for" tag does not support "joined by" anymore
+ * the "autoescape" first argument is now "true"/"false" (instead of "on"/"off")
+ * the "parent" tag has been replaced by a "parent" function ({{ parent() }} instead of {% parent %})
+ * the "display" tag has been replaced by a "block" function ({{ block('title') }} instead of {% display title %})
+ * removed the grammar and simple token parser (moved to the Twig Extensions repository)
+
+Changes:
+
+ * added "needs_context" option for filters and functions (the context is then passed as a first argument)
+ * added global variables support
+ * made macros return their value instead of echoing directly (fixes calling a macro in sandbox mode)
+ * added the "from" tag to import macros as functions
+ * added support for functions (a function is just syntactic sugar for a getAttribute() call)
+ * made macros callable when sandbox mode is enabled
+ * added an exception when a macro uses a reserved name
+ * the "default" filter now uses the "empty" test instead of just checking for null
+ * added the "empty" test
+
+* 0.9.10 (2010-12-16)
+
+Backward incompatibilities:
+
+ * The Escaper extension is enabled by default, which means that all displayed
+   variables are now automatically escaped. You can revert to the previous
+   behavior by removing the extension via $env->removeExtension('escaper')
+   or just set the 'autoescape' option to 'false'.
+ * removed the "without loop" attribute for the "for" tag (not needed anymore
+   as the Optimizer take care of that for most cases)
+ * arrays and hashes have now a different syntax
+     * arrays keep the same syntax with square brackets: [1, 2]
+     * hashes now use curly braces (["a": "b"] should now be written as {"a": "b"})
+     * support for "arrays with keys" and "hashes without keys" is not supported anymore ([1, "foo": "bar"] or {"foo": "bar", 1})
+ * the i18n extension is now part of the Twig Extensions repository
+
+Changes:
+
+ * added the merge filter
+ * removed 'is_escaper' option for filters (a left over from the previous version) -- you must use 'is_safe' now instead
+ * fixed usage of operators as method names (like is, in, and not)
+ * changed the order of execution for node visitors
+ * fixed default() filter behavior when used with strict_variables set to on
+ * fixed filesystem loader compatibility with PHAR files
+ * enhanced error messages when an unexpected token is parsed in an expression
+ * fixed filename not being added to syntax error messages
+ * added the autoescape option to enable/disable autoescaping
+ * removed the newline after a comment (mimics PHP behavior)
+ * added a syntax error exception when parent block is used on a template that does not extend another one
+ * made the Escaper extension enabled by default
+ * fixed sandbox extension when used with auto output escaping
+ * fixed escaper when wrapping a Twig_Node_Print (the original class must be preserved)
+ * added an Optimizer extension (enabled by default; optimizes "for" loops and "raw" filters)
+ * added priority to node visitors
+
+* 0.9.9 (2010-11-28)
+
+Backward incompatibilities:
+ * the self special variable has been renamed to _self
+ * the odd and even filters are now tests:
+     {{ foo|odd }} must now be written {{ foo is odd }}
+ * the "safe" filter has been renamed to "raw"
+ * in Node classes,
+        sub-nodes are now accessed via getNode() (instead of property access)
+        attributes via getAttribute() (instead of array access)
+ * the urlencode filter had been renamed to url_encode
+ * the include tag now merges the passed variables with the current context by default
+   (the old behavior is still possible by adding the "only" keyword)
+ * moved Exceptions to Twig_Error_* (Twig_SyntaxError/Twig_RuntimeError are now Twig_Error_Syntax/Twig_Error_Runtime)
+ * removed support for {{ 1 < i < 3 }} (use {{ i > 1 and i < 3 }} instead)
+ * the "in" filter has been removed ({{ a|in(b) }} should now be written {{ a in b }})
+
+Changes:
+ * added file and line to Twig_Error_Runtime exceptions thrown from Twig_Template
+ * changed trans tag to accept any variable for the plural count
+ * fixed sandbox mode (__toString() method check was not enforced if called implicitly from complex statements)
+ * added the ** (power) operator
+ * changed the algorithm used for parsing expressions
+ * added the spaceless tag
+ * removed trim_blocks option
+ * added support for is*() methods for attributes (foo.bar now looks for foo->getBar() or foo->isBar())
+ * changed all exceptions to extend Twig_Error
+ * fixed unary expressions ({{ not(1 or 0) }})
+ * fixed child templates (with an extend tag) that uses one or more imports
+ * added support for {{ 1 not in [2, 3] }} (more readable than the current {{ not (1 in [2, 3]) }})
+ * escaping has been rewritten
+ * the implementation of template inheritance has been rewritten
+   (blocks can now be called individually and still work with inheritance)
+ * fixed error handling for if tag when a syntax error occurs within a subparse process
+ * added a way to implement custom logic for resolving token parsers given a tag name
+ * fixed js escaper to be stricter (now uses a whilelist-based js escaper)
+ * added the following filers: "constant", "trans", "replace", "json_encode"
+ * added a "constant" test
+ * fixed objects with __toString() not being autoescaped
+ * fixed subscript expressions when calling __call() (methods now keep the case)
+ * added "test" feature (accessible via the "is" operator)
+ * removed the debug tag (should be done in an extension)
+ * fixed trans tag when no vars are used in plural form
+ * fixed race condition when writing template cache
+ * added the special _charset variable to reference the current charset
+ * added the special _context variable to reference the current context
+ * renamed self to _self (to avoid conflict)
+ * fixed Twig_Template::getAttribute() for protected properties
+
+* 0.9.8 (2010-06-28)
+
+Backward incompatibilities:
+ * the trans tag plural count is now attached to the plural tag:
+    old: `{% trans count %}...{% plural %}...{% endtrans %}`
+    new: `{% trans %}...{% plural count %}...{% endtrans %}`
+
+ * added a way to translate strings coming from a variable ({% trans var %})
+ * fixed trans tag when used with the Escaper extension
+ * fixed default cache umask
+ * removed Twig_Template instances from the debug tag output
+ * fixed objects with __isset() defined
+ * fixed set tag when used with a capture
+ * fixed type hinting for Twig_Environment::addFilter() method
+
+* 0.9.7 (2010-06-12)
+
+Backward incompatibilities:
+ * changed 'as' to '=' for the set tag ({% set title as "Title" %} must now be {% set title = "Title" %})
+ * removed the sandboxed attribute of the include tag (use the new sandbox tag instead)
+ * refactored the Node system (if you have custom nodes, you will have to update them to use the new API)
+
+ * added self as a special variable that refers to the current template (useful for importing macros from the current template)
+ * added Twig_Template instance support to the include tag
+ * added support for dynamic and conditional inheritance ({% extends some_var %} and {% extends standalone ? "minimum" : "base" %})
+ * added a grammar sub-framework to ease the creation of custom tags
+ * fixed the for tag for large arrays (some loop variables are now only available for arrays and objects that implement the Countable interface)
+ * removed the Twig_Resource::resolveMissingFilter() method
+ * fixed the filter tag which did not apply filtering to included files
+ * added a bunch of unit tests
+ * added a bunch of phpdoc
+ * added a sandbox tag in the sandbox extension
+ * changed the date filter to support any date format supported by DateTime
+ * added strict_variable setting to throw an exception when an invalid variable is used in a template (disabled by default)
+ * added the lexer, parser, and compiler as arguments to the Twig_Environment constructor
+ * changed the cache option to only accepts an explicit path to a cache directory or false
+ * added a way to add token parsers, filters, and visitors without creating an extension
+ * added three interfaces: Twig_NodeInterface, Twig_TokenParserInterface, and Twig_FilterInterface
+ * changed the generated code to match the new coding standards
+ * fixed sandbox mode (__toString() method check was not enforced if called implicitly from a simple statement like {{ article }})
+ * added an exception when a child template has a non-empty body (as it is always ignored when rendering)
+
+* 0.9.6 (2010-05-12)
+
+ * fixed variables defined outside a loop and for which the value changes in a for loop
+ * fixed the test suite for PHP 5.2 and older versions of PHPUnit
+ * added support for __call() in expression resolution
+ * fixed node visiting for macros (macros are now visited by visitors as any other node)
+ * fixed nested block definitions with a parent call (rarely useful but nonetheless supported now)
+ * added the cycle filter
+ * fixed the Lexer when mbstring.func_overload is used with an mbstring.internal_encoding different from ASCII
+ * added a long-syntax for the set tag ({% set foo %}...{% endset %})
+ * unit tests are now powered by PHPUnit
+ * added support for gettext via the `i18n` extension
+ * fixed twig_capitalize_string_filter() and fixed twig_length_filter() when used with UTF-8 values
+ * added a more useful exception if an if tag is not closed properly
+ * added support for escaping strategy in the autoescape tag
+ * fixed lexer when a template has a big chunk of text between/in a block
+
+* 0.9.5 (2010-01-20)
+
+As for any new release, don't forget to remove all cached templates after
+upgrading.
+
+If you have defined custom filters, you MUST upgrade them for this release. To
+upgrade, replace "array" with "new Twig_Filter_Function", and replace the
+environment constant by the "needs_environment" option:
+
+  // before
+  'even'   => array('twig_is_even_filter', false),
+  'escape' => array('twig_escape_filter', true),
+
+  // after
+  'even'   => new Twig_Filter_Function('twig_is_even_filter'),
+  'escape' => new Twig_Filter_Function('twig_escape_filter', array('needs_environment' => true)),
+
+If you have created NodeTransformer classes, you will need to upgrade them to
+the new interface (please note that the interface is not yet considered
+stable).
+
+ * fixed list nodes that did not extend the Twig_NodeListInterface
+ * added the "without loop" option to the for tag (it disables the generation of the loop variable)
+ * refactored node transformers to node visitors
+ * fixed automatic-escaping for blocks
+ * added a way to specify variables to pass to an included template
+ * changed the automatic-escaping rules to be more sensible and more configurable in custom filters (the documentation lists all the rules)
+ * improved the filter system to allow object methods to be used as filters
+ * changed the Array and String loaders to actually make use of the cache mechanism
+ * included the default filter function definitions in the extension class files directly (Core, Escaper)
+ * added the // operator (like the floor() PHP function)
+ * added the .. operator (as a syntactic sugar for the range filter when the step is 1)
+ * added the in operator (as a syntactic sugar for the in filter)
+ * added the following filters in the Core extension: in, range
+ * added support for arrays (same behavior as in PHP, a mix between lists and dictionaries, arrays and hashes)
+ * enhanced some error messages to provide better feedback in case of parsing errors
+
+* 0.9.4 (2009-12-02)
+
+If you have custom loaders, you MUST upgrade them for this release: The
+Twig_Loader base class has been removed, and the Twig_LoaderInterface has also
+been changed (see the source code for more information or the documentation).
+
+ * added support for DateTime instances for the date filter
+ * fixed loop.last when the array only has one item
+ * made it possible to insert newlines in tag and variable blocks
+ * fixed a bug when a literal '\n' were present in a template text
+ * fixed bug when the filename of a template contains */
+ * refactored loaders
+
+* 0.9.3 (2009-11-11)
+
+This release is NOT backward compatible with the previous releases.
+
+  The loaders do not take the cache and autoReload arguments anymore. Instead,
+  the Twig_Environment class has two new options: cache and auto_reload.
+  Upgrading your code means changing this kind of code:
+
+      $loader = new Twig_Loader_Filesystem('/path/to/templates', '/path/to/compilation_cache', true);
+      $twig = new Twig_Environment($loader);
+
+  to something like this:
+
+      $loader = new Twig_Loader_Filesystem('/path/to/templates');
+      $twig = new Twig_Environment($loader, array(
+        'cache' => '/path/to/compilation_cache',
+        'auto_reload' => true,
+      ));
+
+ * deprecated the "items" filter as it is not needed anymore
+ * made cache and auto_reload options of Twig_Environment instead of arguments of Twig_Loader
+ * optimized template loading speed
+ * removed output when an error occurs in a template and render() is used
+ * made major speed improvements for loops (up to 300% on even the smallest loops)
+ * added properties as part of the sandbox mode
+ * added public properties support (obj.item can now be the item property on the obj object)
+ * extended set tag to support expression as value ({% set foo as 'foo' ~ 'bar' %} )
+ * fixed bug when \ was used in HTML
+
+* 0.9.2 (2009-10-29)
+
+ * made some speed optimizations
+ * changed the cache extension to .php
+ * added a js escaping strategy
+ * added support for short block tag

+ * made lexer more flexible as you can now change the default delimiters
+ * added set tag
+ * changed default directory permission when cache dir does not exist (more secure)
+ * added macro support
+ * changed filters first optional argument to be a Twig_Environment instance instead of a Twig_Template instance
+ * made Twig_Autoloader::autoload() a static method
+ * avoid writing template file if an error occurs
+ * added $ escaping when outputting raw strings

+Twig, the flexible, fast, and secure template language for PHP
+==============================================================
+
+[![Build Status](https://secure.travis-ci.org/fabpot/Twig.png?branch=master)](http://travis-ci.org/fabpot/Twig)
+
+Twig is a template language for PHP, released under the new BSD license (code
+and documentation).
+
+Twig uses a syntax similar to the Django and Jinja template languages which
+inspired the Twig runtime environment.

+Extending Twig
+==============
+
+.. caution::
+
+    This section describes how to extend Twig as of **Twig 1.12**. If you are
+    using an older version, read the :doc:`legacy<advanced_legacy>` chapter
+    instead.
+
+Twig can be extended in many ways; you can add extra tags, filters, tests,
+operators, global variables, and functions. You can even extend the parser
+itself with node visitors.
+
+.. note::
+
+    The first section of this chapter describes how to extend Twig easily. If
+    you want to reuse your changes in different projects or if you want to
+    share them with others, you should then create an extension as described
+    in the following section.
+
+.. caution::
+
+    When extending Twig without creating an extension, Twig won't be able to
+    recompile your templates when the PHP code is updated. To see your changes
+    in real-time, either disable template caching or package your code into an
+    extension (see the next section of this chapter).
+
+Before extending Twig, you must understand the differences between all the
+different possible extension points and when to use them.
+
+First, remember that Twig has two main language constructs:
+
+* ``{{ }}``: used to print the result of an expression evaluation;
+
+* ``{% %}``: used to execute statements.
+
+To understand why Twig exposes so many extension points, let's see how to
+implement a *Lorem ipsum* generator (it needs to know the number of words to
+generate).
+
+You can use a ``lipsum`` *tag*:
+
+.. code-block:: jinja
+
+    {% lipsum 40 %}
+
+That works, but using a tag for ``lipsum`` is not a good idea for at least
+three main reasons:
+
+* ``lipsum`` is not a language construct;
+* The tag outputs something;
+* The tag is not flexible as you cannot use it in an expression:
+
+  .. code-block:: jinja
+
+      {{ 'some text' ~ {% lipsum 40 %} ~ 'some more text' }}
+
+In fact, you rarely need to create tags; and that's good news because tags are
+the most complex extension point of Twig.
+
+Now, let's use a ``lipsum`` *filter*:
+
+.. code-block:: jinja
+
+    {{ 40|lipsum }}
+
+Again, it works, but it looks weird. A filter transforms the passed value to
+something else but here we use the value to indicate the number of words to
+generate (so, ``40`` is an argument of the filter, not the value we want to
+transform).
+
+Next, let's use a ``lipsum`` *function*:
+
+.. code-block:: jinja
+
+    {{ lipsum(40) }}
+
+Here we go. For this specific example, the creation of a function is the
+extension point to use. And you can use it anywhere an expression is accepted:
+
+.. code-block:: jinja
+
+    {{ 'some text' ~ lipsum(40) ~ 'some more text' }}
+
+    {% set lipsum = lipsum(40) %}
+
+Last but not the least, you can also use a *global* object with a method able
+to generate lorem ipsum text:
+
+.. code-block:: jinja
+
+    {{ text.lipsum(40) }}
+
+As a rule of thumb, use functions for frequently used features and global
+objects for everything else.
+
+Keep in mind the following when you want to extend Twig:
+
+========== ========================== ========== =========================
+What?      Implementation difficulty? How often? When?
+========== ========================== ========== =========================
+*macro*    trivial                    frequent   Content generation
+*global*   trivial                    frequent   Helper object
+*function* trivial                    frequent   Content generation
+*filter*   trivial                    frequent   Value transformation
+*tag*      complex                    rare       DSL language construct
+*test*     trivial                    rare       Boolean decision
+*operator* trivial                    rare       Values transformation
+========== ========================== ========== =========================
+
+Globals
+-------
+
+A global variable is like any other template variable, except that it's
+available in all templates and macros::
+
+    $twig = new Twig_Environment($loader);
+    $twig->addGlobal('text', new Text());
+
+You can then use the ``text`` variable anywhere in a template:
+
+.. code-block:: jinja
+
+    {{ text.lipsum(40) }}
+
+Filters
+-------
+
+Creating a filter is as simple as associating a name with a PHP callable::
+
+    // an anonymous function
+    $filter = new Twig_SimpleFilter('rot13', function ($string) {
+        return str_rot13($string);
+    });
+
+    // or a simple PHP function
+    $filter = new Twig_SimpleFilter('rot13', 'str_rot13');
+
+    // or a class method
+    $filter = new Twig_SimpleFilter('rot13', array('SomeClass', 'rot13Filter'));
+
+The first argument passed to the ``Twig_SimpleFilter`` constructor is the name
+of the filter you will use in templates and the second one is the PHP callable
+to associate with it.
+
+Then, add the filter to your Twig environment::
+
+    $twig = new Twig_Environment($loader);
+    $twig->addFilter($filter);
+
+And here is how to use it in a template:
+
+.. code-block:: jinja
+
+    {{ 'Twig'|rot13 }}
+
+    {# will output Gjvt #}
+
+When called by Twig, the PHP callable receives the left side of the filter
+(before the pipe ``|``) as the first argument and the extra arguments passed
+to the filter (within parentheses ``()``) as extra arguments.
+
+For instance, the following code:
+
+.. code-block:: jinja
+
+    {{ 'TWIG'|lower }}
+    {{ now|date('d/m/Y') }}
+
+is compiled to something like the following::
+
+    <?php echo strtolower('TWIG') ?>
+    <?php echo twig_date_format_filter($now, 'd/m/Y') ?>
+
+The ``Twig_SimpleFilter`` class takes an array of options as its last
+argument::
+
+    $filter = new Twig_SimpleFilter('rot13', 'str_rot13', $options);
+
+Environment aware Filters
+~~~~~~~~~~~~~~~~~~~~~~~~~
+
+If you want to access the current environment instance in your filter, set the
+``needs_environment`` option to ``true``; Twig will pass the current
+environment as the first argument to the filter call::
+
+    $filter = new Twig_SimpleFilter('rot13', function (Twig_Environment $env, $string) {
+        // get the current charset for instance
+        $charset = $env->getCharset();
+
+        return str_rot13($string);
+    }, array('needs_environment' => true));
+
+Context aware Filters
+~~~~~~~~~~~~~~~~~~~~~
+
+If you want to access the current context in your filter, set the
+``needs_context`` option to ``true``; Twig will pass the current context as
+the first argument to the filter call (or the second one if
+``needs_environment`` is also set to ``true``)::
+
+    $filter = new Twig_SimpleFilter('rot13', function ($context, $string) {
+        // ...
+    }, array('needs_context' => true));
+
+    $filter = new Twig_SimpleFilter('rot13', function (Twig_Environment $env, $context, $string) {
+        // ...
+    }, array('needs_context' => true, 'needs_environment' => true));
+
+Automatic Escaping
+~~~~~~~~~~~~~~~~~~
+
+If automatic escaping is enabled, the output of the filter may be escaped
+before printing. If your filter acts as an escaper (or explicitly outputs html
+or JavaScript code), you will want the raw output to be printed. In such a
+case, set the ``is_safe`` option::
+
+    $filter = new Twig_SimpleFilter('nl2br', 'nl2br', array('is_safe' => array('html')));
+
+Some filters may need to work on input that is already escaped or safe, for
+example when adding (safe) html tags to originally unsafe output. In such a
+case, set the ``pre_escape`` option to escape the input data before it is run
+through your filter::
+
+    $filter = new Twig_SimpleFilter('somefilter', 'somefilter', array('pre_escape' => 'html', 'is_safe' => array('html')));
+
+Dynamic Filters
+~~~~~~~~~~~~~~~
+
+A filter name containing the special ``*`` character is a dynamic filter as
+the ``*`` can be any string::
+
+    $filter = new Twig_SimpleFilter('*_path', function ($name, $arguments) {
+        // ...
+    });
+
+The following filters will be matched by the above defined dynamic filter:
+
+* ``product_path``
+* ``category_path``
+
+A dynamic filter can define more than one dynamic parts::
+
+    $filter = new Twig_SimpleFilter('*_path_*', function ($name, $suffix, $arguments) {
+        // ...
+    });
+
+The filter will receive all dynamic part values before the normal filter
+arguments, but after the environment and the context. For instance, a call to
+``'foo'|a_path_b()`` will result in the following arguments to be passed to
+the filter: ``('a', 'b', 'foo')``.
+
+Functions
+---------
+
+Functions are defined in the exact same way as filters, but you need to create
+an instance of ``Twig_SimpleFunction``::
+
+    $twig = new Twig_Environment($loader);
+    $function = new Twig_SimpleFunction('function_name', function () {
+        // ...
+    });
+    $twig->addFunction($function);
+
+Functions support the same features as filters, except for the ``pre_escape``
+and ``preserves_safety`` options.
+
+Tests
+-----
+
+Tests are defined in the exact same way as filters and functions, but you need
+to create an instance of ``Twig_SimpleTest``::
+
+    $twig = new Twig_Environment($loader);
+    $test = new Twig_SimpleTest('test_name', function () {
+        // ...
+    });
+    $twig->addTest($test);
+
+Tests allow you to create custom application specific logic for evaluating
+boolean conditions. As a simple, example let's create a Twig test that checks if
+objects are 'red'::
+
+    $twig = new Twig_Environment($loader)
+    $test = new Twig_SimpleTest('red', function ($value) {
+        if (isset($value->color) && $value->color == 'red') {
+            return true;
+        }
+        if (isset($value->paint) && $value->paint == 'red') {
+            return true;
+        }
+        return false;
+    });
+    $twig->addTest($test);
+
+Test functions should always return true/false.
+
+When creating tests you can use the ``node_class`` option to provide custom test
+compilation. This is useful if your test can be compiled into PHP primitives.
+This is used by many of the tests built into Twig::
+
+    $twig = new Twig_Environment($loader)
+    $test = new Twig_SimpleTest(
+        'odd',
+        null,
+        array('node_class' => 'Twig_Node_Expression_Test_Odd'));
+    $twig->addTest($test);
+
+    class Twig_Node_Expression_Test_Odd extends Twig_Node_Expression_Test
+    {
+        public function compile(Twig_Compiler $compiler)
+        {
+            $compiler
+                ->raw('(')
+                ->subcompile($this->getNode('node'))
+                ->raw(' % 2 == 1')
+                ->raw(')')
+            ;
+        }
+    }
+
+The above example, shows how you can create tests that use a node class. The
+node class has access to one sub-node called 'node'. This sub-node contains the
+value that is being tested. When the ``odd`` filter is used in code like:
+
+.. code-block:: jinja
+
+    {% if my_value is odd %}
+
+The ``node`` sub-node will contain an expression of ``my_value``. Node based
+tests also have access to the ``arguments`` node. This node will contain the
+various other arguments that have been provided to your test.
+
+Tags
+----
+
+One of the most exciting feature of a template engine like Twig is the
+possibility to define new language constructs. This is also the most complex
+feature as you need to understand how Twig's internals work.
+
+Let's create a simple ``set`` tag that allows the definition of simple
+variables from within a template. The tag can be used like follows:
+
+.. code-block:: jinja
+
+    {% set name = "value" %}
+
+    {{ name }}
+
+    {# should output value #}
+
+.. note::
+
+    The ``set`` tag is part of the Core extension and as such is always
+    available. The built-in version is slightly more powerful and supports
+    multiple assignments by default (cf. the template designers chapter for
+    more information).
+
+Three steps are needed to define a new tag:
+
+* Defining a Token Parser class (responsible for parsing the template code);
+
+* Defining a Node class (responsible for converting the parsed code to PHP);
+
+* Registering the tag.
+
+Registering a new tag
+~~~~~~~~~~~~~~~~~~~~~
+
+Adding a tag is as simple as calling the ``addTokenParser`` method on the
+``Twig_Environment`` instance::
+
+    $twig = new Twig_Environment($loader);
+    $twig->addTokenParser(new Project_Set_TokenParser());
+
+Defining a Token Parser
+~~~~~~~~~~~~~~~~~~~~~~~
+
+Now, let's see the actual code of this class::
+
+    class Project_Set_TokenParser extends Twig_TokenParser
+    {
+        public function parse(Twig_Token $token)
+        {
+            $parser = $this->parser;
+            $stream = $parser->getStream();
+
+            $name = $stream->expect(Twig_Token::NAME_TYPE)->getValue();
+            $stream->expect(Twig_Token::OPERATOR_TYPE, '=');
+            $value = $parser->getExpressionParser()->parseExpression();
+            $stream->expect(Twig_Token::BLOCK_END_TYPE);
+
+            return new Project_Set_Node($name, $value, $token->getLine(), $this->getTag());
+        }
+
+        public function getTag()
+        {
+            return 'set';
+        }
+    }
+
+The ``getTag()`` method must return the tag we want to parse, here ``set``.
+
+The ``parse()`` method is invoked whenever the parser encounters a ``set``
+tag. It should return a ``Twig_Node`` instance that represents the node (the
+``Project_Set_Node`` calls creating is explained in the next section).
+
+The parsing process is simplified thanks to a bunch of methods you can call
+from the token stream (``$this->parser->getStream()``):
+
+* ``getCurrent()``: Gets the current token in the stream.
+
+* ``next()``: Moves to the next token in the stream, *but returns the old one*.
+
+* ``test($type)``, ``test($value)`` or ``test($type, $value)``: Determines whether
+  the current token is of a particular type or value (or both). The value may be an
+  array of several possible values.
+
+* ``expect($type[, $value[, $message]])``: If the current token isn't of the given
+  type/value a syntax error is thrown. Otherwise, if the type and value are correct,
+  the token is returned and the stream moves to the next token.
+
+* ``look()``: Looks a the next token without consuming it.
+
+Parsing expressions is done by calling the ``parseExpression()`` like we did for
+the ``set`` tag.
+
+.. tip::
+
+    Reading the existing ``TokenParser`` classes is the best way to learn all
+    the nitty-gritty details of the parsing process.
+
+Defining a Node
+~~~~~~~~~~~~~~~
+
+The ``Project_Set_Node`` class itself is rather simple::
+
+    class Project_Set_Node extends Twig_Node
+    {
+        public function __construct($name, Twig_Node_Expression $value, $line, $tag = null)
+        {
+            parent::__construct(array('value' => $value), array('name' => $name), $line, $tag);
+        }
+
+        public function compile(Twig_Compiler $compiler)
+        {
+            $compiler
+                ->addDebugInfo($this)
+                ->write('$context[\''.$this->getAttribute('name').'\'] = ')
+                ->subcompile($this->getNode('value'))
+                ->raw(";\n")
+            ;
+        }
+    }
+
+The compiler implements a fluid interface and provides methods that helps the
+developer generate beautiful and readable PHP code:
+
+* ``subcompile()``: Compiles a node.
+
+* ``raw()``: Writes the given string as is.
+
+* ``write()``: Writes the given string by adding indentation at the beginning
+  of each line.
+
+* ``string()``: Writes a quoted string.
+
+* ``repr()``: Writes a PHP representation of a given value (see
+  ``Twig_Node_For`` for a usage example).
+
+* ``addDebugInfo()``: Adds the line of the original template file related to
+  the current node as a comment.
+
+* ``indent()``: Indents the generated code (see ``Twig_Node_Block`` for a
+  usage example).
+
+* ``outdent()``: Outdents the generated code (see ``Twig_Node_Block`` for a
+  usage example).
+
+.. _creating_extensions:
+
+Creating an Extension
+---------------------
+
+The main motivation for writing an extension is to move often used code into a
+reusable class like adding support for internationalization. An extension can
+define tags, filters, tests, operators, global variables, functions, and node
+visitors.
+
+Creating an extension also makes for a better separation of code that is
+executed at compilation time and code needed at runtime. As such, it makes
+your code faster.
+
+Most of the time, it is useful to create a single extension for your project,
+to host all the specific tags and filters you want to add to Twig.
+
+.. tip::
+
+    When packaging your code into an extension, Twig is smart enough to
+    recompile your templates whenever you make a change to it (when
+    ``auto_reload`` is enabled).
+
+.. note::
+
+    Before writing your own extensions, have a look at the Twig official
+    extension repository: http://github.com/fabpot/Twig-extensions.
+
+An extension is a class that implements the following interface::
+
+    interface Twig_ExtensionInterface
+    {
+        /**
+         * Initializes the runtime environment.
+         *
+         * This is where you can load some file that contains filter functions for instance.
+         *
+         * @param Twig_Environment $environment The current Twig_Environment instance
+         */
+        function initRuntime(Twig_Environment $environment);
+
+        /**
+         * Returns the token parser instances to add to the existing list.
+         *
+         * @return array An array of Twig_TokenParserInterface or Twig_TokenParserBrokerInterface instances
+         */
+        function getTokenParsers();
+
+        /**
+         * Returns the node visitor instances to add to the existing list.
+         *
+         * @return array An array of Twig_NodeVisitorInterface instances
+         */
+        function getNodeVisitors();
+
+        /**
+         * Returns a list of filters to add to the existing list.
+         *
+         * @return array An array of filters
+         */
+        function getFilters();
+
+        /**
+         * Returns a list of tests to add to the existing list.
+         *
+         * @return array An array of tests
+         */
+        function getTests();
+
+        /**
+         * Returns a list of functions to add to the existing list.
+         *
+         * @return array An array of functions
+         */
+        function getFunctions();
+
+        /**
+         * Returns a list of operators to add to the existing list.
+         *
+         * @return array An array of operators
+         */
+        function getOperators();
+
+        /**
+         * Returns a list of global variables to add to the existing list.
+         *
+         * @return array An array of global variables
+         */
+        function getGlobals();
+
+        /**
+         * Returns the name of the extension.
+         *
+         * @return string The extension name
+         */
+        function getName();
+    }
+
+To keep your extension class clean and lean, it can inherit from the built-in
+``Twig_Extension`` class instead of implementing the whole interface. That
+way, you just need to implement the ``getName()`` method as the
+``Twig_Extension`` provides empty implementations for all other methods.
+
+The ``getName()`` method must return a unique identifier for your extension.
+
+Now, with this information in mind, let's create the most basic extension
+possible::
+
+    class Project_Twig_Extension extends Twig_Extension
+    {
+        public function getName()
+        {
+            return 'project';
+        }
+    }
+
+.. note::
+
+    Of course, this extension does nothing for now. We will customize it in
+    the next sections.
+
+Twig does not care where you save your extension on the filesystem, as all
+extensions must be registered explicitly to be available in your templates.
+
+You can register an extension by using the ``addExtension()`` method on your
+main ``Environment`` object::
+
+    $twig = new Twig_Environment($loader);
+    $twig->addExtension(new Project_Twig_Extension());
+
+Of course, you need to first load the extension file by either using
+``require_once()`` or by using an autoloader (see `spl_autoload_register()`_).
+
+.. tip::
+
+    The bundled extensions are great examples of how extensions work.
+
+Globals
+~~~~~~~
+
+Global variables can be registered in an extension via the ``getGlobals()``
+method::
+
+    class Project_Twig_Extension extends Twig_Extension
+    {
+        public function getGlobals()
+        {
+            return array(
+                'text' => new Text(),
+            );
+        }
+
+        // ...
+    }
+
+Functions
+~~~~~~~~~
+
+Functions can be registered in an extension via the ``getFunctions()``
+method::
+
+    class Project_Twig_Extension extends Twig_Extension
+    {
+        public function getFunctions()
+        {
+            return array(
+                new Twig_SimpleFunction('lipsum', 'generate_lipsum'),
+            );
+        }
+
+        // ...
+    }
+
+Filters
+~~~~~~~
+
+To add a filter to an extension, you need to override the ``getFilters()``
+method. This method must return an array of filters to add to the Twig
+environment::
+
+    class Project_Twig_Extension extends Twig_Extension
+    {
+        public function getFilters()
+        {
+            return array(
+                new Twig_SimpleFilter('rot13', 'str_rot13'),
+            );
+        }
+
+        // ...
+    }
+
+Tags
+~~~~
+
+Adding a tag in an extension can be done by overriding the
+``getTokenParsers()`` method. This method must return an array of tags to add
+to the Twig environment::
+
+    class Project_Twig_Extension extends Twig_Extension
+    {
+        public function getTokenParsers()
+        {
+            return array(new Project_Set_TokenParser());
+        }
+
+        // ...
+    }
+
+In the above code, we have added a single new tag, defined by the
+``Project_Set_TokenParser`` class. The ``Project_Set_TokenParser`` class is
+responsible for parsing the tag and compiling it to PHP.
+
+Operators
+~~~~~~~~~
+
+The ``getOperators()`` methods allows to add new operators. Here is how to add
+``!``, ``||``, and ``&&`` operators::
+
+    class Project_Twig_Extension extends Twig_Extension
+    {
+        public function getOperators()
+        {
+            return array(
+                array(
+                    '!' => array('precedence' => 50, 'class' => 'Twig_Node_Expression_Unary_Not'),
+                ),
+                array(
+                    '||' => array('precedence' => 10, 'class' => 'Twig_Node_Expression_Binary_Or', 'associativity' => Twig_ExpressionParser::OPERATOR_LEFT),
+                    '&&' => array('precedence' => 15, 'class' => 'Twig_Node_Expression_Binary_And', 'associativity' => Twig_ExpressionParser::OPERATOR_LEFT),
+                ),
+            );
+        }
+
+        // ...
+    }
+
+Tests
+~~~~~
+
+The ``getTests()`` methods allows to add new test functions::
+
+    class Project_Twig_Extension extends Twig_Extension
+    {
+        public function getTests()
+        {
+            return array(
+                new Twig_SimpleTest('even', 'twig_test_even'),
+            );
+        }
+
+        // ...
+    }
+
+Overloading
+-----------
+
+To overload an already defined filter, test, operator, global variable, or
+function, define it again **as late as possible**::
+
+    $twig = new Twig_Environment($loader);
+    $twig->addFilter(new Twig_SimpleFilter('date', function ($timestamp, $format = 'F j, Y H:i') {
+        // do something different from the built-in date filter
+    }));
+
+Here, we have overloaded the built-in ``date`` filter with a custom one.
+
+That also works with an extension::
+
+    class MyCoreExtension extends Twig_Extension
+    {
+        public function getFilters()
+        {
+            return array(
+                new Twig_SimpleFilter('date', array($this, 'dateFilter')),
+            );
+        }
+
+        public function dateFilter($timestamp, $format = 'F j, Y H:i')
+        {
+            // do something different from the built-in date filter
+        }
+
+        public function getName()
+        {
+            return 'project';
+        }
+    }
+
+    $twig = new Twig_Environment($loader);
+    $twig->addExtension(new MyCoreExtension());
+
+.. caution::
+
+    Note that overloading the built-in Twig elements is not recommended as it
+    might be confusing.
+
+Testing an Extension
+--------------------
+
+Functional Tests
+~~~~~~~~~~~~~~~~
+
+You can create functional tests for extensions simply by creating the
+following file structure in your test directory::
+
+    Fixtures/
+        filters/
+            foo.test
+            bar.test
+        functions/
+            foo.test
+            bar.test
+        tags/
+            foo.test
+            bar.test
+    IntegrationTest.php
+
+The ``IntegrationTest.php`` file should look like this::
+
+    class Project_Tests_IntegrationTest extends Twig_Test_IntegrationTestCase
+    {
+        public function getExtensions()
+        {
+            return array(
+                new Project_Twig_Extension1(),
+                new Project_Twig_Extension2(),
+            );
+        }
+
+        public function getFixturesDir()
+        {
+            return dirname(__FILE__).'/Fixtures/';
+        }
+    }
+
+Fixtures examples can be found within the Twig repository
+`tests/Twig/Fixtures`_ directory.
+
+Node Tests
+~~~~~~~~~~
+
+Testing the node visitors can be complex, so extend your test cases from
+``Twig_Test_NodeTestCase``. Examples can be found in the Twig repository
+`tests/Twig/Node`_ directory.

+Extending Twig
+==============
+
+.. caution::
+
+    This section describes how to extends Twig for versions **older than
+    1.12**. If you are using a newer version, read the :doc:`newer<advanced>`
+    chapter instead.
+
+Twig can be extended in many ways; you can add extra tags, filters, tests,
+operators, global variables, and functions. You can even extend the parser
+itself with node visitors.
+
+.. note::
+
+    The first section of this chapter describes how to extend Twig easily. If
+    you want to reuse your changes in different projects or if you want to
+    share them with others, you should then create an extension as described
+    in the following section.
+
+.. caution::
+
+    When extending Twig by calling methods on the Twig environment instance,
+    Twig won't be able to recompile your templates when the PHP code is
+    updated. To see your changes in real-time, either disable template caching
+    or package your code into an extension (see the next section of this
+    chapter).
+
+Before extending Twig, you must understand the differences between all the
+different possible extension points and when to use them.
+
+First, remember that Twig has two main language constructs:
+
+* ``{{ }}``: used to print the result of an expression evaluation;
+
+* ``{% %}``: used to execute statements.
+
+To understand why Twig exposes so many extension points, let's see how to
+implement a *Lorem ipsum* generator (it needs to know the number of words to
+generate).
+
+You can use a ``lipsum`` *tag*:
+
+.. code-block:: jinja
+
+    {% lipsum 40 %}
+
+That works, but using a tag for ``lipsum`` is not a good idea for at least
+three main reasons:
+
+* ``lipsum`` is not a language construct;
+* The tag outputs something;
+* The tag is not flexible as you cannot use it in an expression:
+
+  .. code-block:: jinja
+
+      {{ 'some text' ~ {% lipsum 40 %} ~ 'some more text' }}
+
+In fact, you rarely need to create tags; and that's good news because tags are
+the most complex extension point of Twig.
+
+Now, let's use a ``lipsum`` *filter*:
+
+.. code-block:: jinja
+
+    {{ 40|lipsum }}
+
+Again, it works, but it looks weird. A filter transforms the passed value to
+something else but here we use the value to indicate the number of words to
+generate (so, ``40`` is an argument of the filter, not the value we want to
+transform).
+
+Next, let's use a ``lipsum`` *function*:
+
+.. code-block:: jinja
+
+    {{ lipsum(40) }}
+
+Here we go. For this specific example, the creation of a function is the
+extension point to use. And you can use it anywhere an expression is accepted:
+
+.. code-block:: jinja
+
+    {{ 'some text' ~ ipsum(40) ~ 'some more text' }}
+
+    {% set ipsum = ipsum(40) %}
+
+Last but not the least, you can also use a *global* object with a method able
+to generate lorem ipsum text:
+
+.. code-block:: jinja
+
+    {{ text.lipsum(40) }}
+
+As a rule of thumb, use functions for frequently used features and global
+objects for everything else.
+
+Keep in mind the following when you want to extend Twig:

+========== ========================== ========== =========================
+
+Globals
+-------
+
+A global variable is like any other template variable, except that it's
+available in all templates and macros::
+
+    $twig = new Twig_Environment($loader);
+    $twig->addGlobal('text', new Text());
+
+You can then use the ``text`` variable anywhere in a template:
+
+.. code-block:: jinja
+
+    {{ text.lipsum(40) }}
+
+Filters
+-------
+
+A filter is a regular PHP function or an object method that takes the left
+side of the filter (before the pipe ``|``) as first argument and the extra
+arguments passed to the filter (within parentheses ``()``) as extra arguments.
+
+Defining a filter is as easy as associating the filter name with a PHP
+callable. For instance, let's say you have the following code in a template:
+
+.. code-block:: jinja
+
+    {{ 'TWIG'|lower }}
+
+When compiling this template to PHP, Twig looks for the PHP callable
+associated with the ``lower`` filter. The ``lower`` filter is a built-in Twig
+filter, and it is simply mapped to the PHP ``strtolower()`` function. After
+compilation, the generated PHP code is roughly equivalent to:
+
+.. code-block:: html+php
+
+    <?php echo strtolower('TWIG') ?>
+
+As you can see, the ``'TWIG'`` string is passed as a first argument to the PHP
+function.
+
+A filter can also take extra arguments like in the following example:
+
+.. code-block:: jinja
+
+    {{ now|date('d/m/Y') }}
+
+In this case, the extra arguments are passed to the function after the main
+argument, and the compiled code is equivalent to:
+
+.. code-block:: html+php
+
+    <?php echo twig_date_format_filter($now, 'd/m/Y') ?>
+
+Let's see how to create a new filter.
+
+In this section, we will create a ``rot13`` filter, which should return the
+`rot13`_ transformation of a string. Here is an example of its usage and the
+expected output:
+
+.. code-block:: jinja
+
+    {{ "Twig"|rot13 }}
+
+    {# should displays Gjvt #}
+
+Adding a filter is as simple as calling the ``addFilter()`` method on the
+``Twig_Environment`` instance::
+
+    $twig = new Twig_Environment($loader);
+    $twig->addFilter('rot13', new Twig_Filter_Function('str_rot13'));
+
+The second argument of ``addFilter()`` is an instance of ``Twig_Filter``.
+Here, we use ``Twig_Filter_Function`` as the filter is a PHP function. The
+first argument passed to the ``Twig_Filter_Function`` constructor is the name
+of the PHP function to call, here ``str_rot13``, a native PHP function.
+
+Let's say I now want to be able to add a prefix before the converted string:
+
+.. code-block:: jinja
+
+    {{ "Twig"|rot13('prefix_') }}
+
+    {# should displays prefix_Gjvt #}
+
+As the PHP ``str_rot13()`` function does not support this requirement, let's
+create a new PHP function::
+
+    function project_compute_rot13($string, $prefix = '')
+    {
+        return $prefix.str_rot13($string);
+    }
+
+As you can see, the ``prefix`` argument of the filter is passed as an extra
+argument to the ``project_compute_rot13()`` function.
+
+Adding this filter is as easy as before::
+
+    $twig->addFilter('rot13', new Twig_Filter_Function('project_compute_rot13'));
+
+For better encapsulation, a filter can also be defined as a static method of a
+class. The ``Twig_Filter_Function`` class can also be used to register such
+static methods as filters::
+
+    $twig->addFilter('rot13', new Twig_Filter_Function('SomeClass::rot13Filter'));
+
+.. tip::
+
+    In an extension, you can also define a filter as a static method of the
+    extension class.
+
+Environment aware Filters
+~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The ``Twig_Filter`` classes take options as their last argument. For instance,
+if you want access to the current environment instance in your filter, set the
+``needs_environment`` option to ``true``::
+
+    $filter = new Twig_Filter_Function('str_rot13', array('needs_environment' => true));
+
+Twig will then pass the current environment as the first argument to the
+filter call::
+
+    function twig_compute_rot13(Twig_Environment $env, $string)
+    {
+        // get the current charset for instance
+        $charset = $env->getCharset();
+
+        return str_rot13($string);
+    }
+
+Automatic Escaping
+~~~~~~~~~~~~~~~~~~
+
+If automatic escaping is enabled, the output of the filter may be escaped
+before printing. If your filter acts as an escaper (or explicitly outputs html
+or javascript code), you will want the raw output to be printed. In such a
+case, set the ``is_safe`` option::
+
+    $filter = new Twig_Filter_Function('nl2br', array('is_safe' => array('html')));
+
+Some filters may need to work on input that is already escaped or safe, for
+example when adding (safe) html tags to originally unsafe output. In such a
+case, set the ``pre_escape`` option to escape the input data before it is run
+through your filter::
+
+    $filter = new Twig_Filter_Function('somefilter', array('pre_escape' => 'html', 'is_safe' => array('html')));
+
+Dynamic Filters
+~~~~~~~~~~~~~~~
+
+.. versionadded:: 1.5
+    Dynamic filters support was added in Twig 1.5.
+
+A filter name containing the special ``*`` character is a dynamic filter as
+the ``*`` can be any string::
+
+    $twig->addFilter('*_path_*', new Twig_Filter_Function('twig_path'));
+
+    function twig_path($name, $arguments)
+    {
+        // ...
+    }
+
+The following filters will be matched by the above defined dynamic filter:
+
+* ``product_path``
+* ``category_path``
+
+A dynamic filter can define more than one dynamic parts::
+
+    $twig->addFilter('*_path_*', new Twig_Filter_Function('twig_path'));
+
+    function twig_path($name, $suffix, $arguments)
+    {
+        // ...
+    }
+
+The filter will receive all dynamic part values before the normal filters
+arguments. For instance, a call to ``'foo'|a_path_b()`` will result in the
+following PHP call: ``twig_path('a', 'b', 'foo')``.
+
+Functions
+---------
+
+A function is a regular PHP function or an object method that can be called from
+templates.
+
+.. code-block:: jinja
+
+    {{ constant("DATE_W3C") }}
+
+When compiling this template to PHP, Twig looks for the PHP callable
+associated with the ``constant`` function. The ``constant`` function is a built-in Twig
+function, and it is simply mapped to the PHP ``constant()`` function. After
+compilation, the generated PHP code is roughly equivalent to:
+
+.. code-block:: html+php
+
+    <?php echo constant('DATE_W3C') ?>
+
+Adding a function is similar to adding a filter. This can be done by calling the
+``addFunction()`` method on the ``Twig_Environment`` instance::
+
+    $twig = new Twig_Environment($loader);
+    $twig->addFunction('functionName', new Twig_Function_Function('someFunction'));
+
+You can also expose extension methods as functions in your templates::
+
+    // $this is an object that implements Twig_ExtensionInterface.
+    $twig = new Twig_Environment($loader);
+    $twig->addFunction('otherFunction', new Twig_Function_Method($this, 'someMethod'));
+
+Functions also support ``needs_environment`` and ``is_safe`` parameters.
+
+Dynamic Functions
+~~~~~~~~~~~~~~~~~
+
+.. versionadded:: 1.5
+    Dynamic functions support was added in Twig 1.5.
+
+A function name containing the special ``*`` character is a dynamic function
+as the ``*`` can be any string::
+
+    $twig->addFunction('*_path', new Twig_Function_Function('twig_path'));
+
+    function twig_path($name, $arguments)
+    {
+        // ...
+    }
+
+The following functions will be matched by the above defined dynamic function:
+
+* ``product_path``
+* ``category_path``
+
+A dynamic function can define more than one dynamic parts::
+
+    $twig->addFilter('*_path_*', new Twig_Filter_Function('twig_path'));
+
+    function twig_path($name, $suffix, $arguments)
+    {
+        // ...
+    }
+
+The function will receive all dynamic part values before the normal functions
+arguments. For instance, a call to ``a_path_b('foo')`` will result in the
+following PHP call: ``twig_path('a', 'b', 'foo')``.
+
+Tags
+----
+
+One of the most exciting feature of a template engine like Twig is the
+possibility to define new language constructs. This is also the most complex
+feature as you need to understand how Twig's internals work.
+
+Let's create a simple ``set`` tag that allows the definition of simple
+variables from within a template. The tag can be used like follows:
+
+.. code-block:: jinja
+
+    {% set name = "value" %}
+
+    {{ name }}
+
+    {# should output value #}
+
+.. note::
+
+    The ``set`` tag is part of the Core extension and as such is always
+    available. The built-in version is slightly more powerful and supports
+    multiple assignments by default (cf. the template designers chapter for
+    more information).
+
+Three steps are needed to define a new tag:
+
+* Defining a Token Parser class (responsible for parsing the template code);
+
+* Defining a Node class (responsible for converting the parsed code to PHP);
+
+* Registering the tag.
+
+Registering a new tag
+~~~~~~~~~~~~~~~~~~~~~
+
+Adding a tag is as simple as calling the ``addTokenParser`` method on the
+``Twig_Environment`` instance::
+
+    $twig = new Twig_Environment($loader);
+    $twig->addTokenParser(new Project_Set_TokenParser());
+
+Defining a Token Parser
+~~~~~~~~~~~~~~~~~~~~~~~
+
+Now, let's see the actual code of this class::
+
+    class Project_Set_TokenParser extends Twig_TokenParser
+    {
+        public function parse(Twig_Token $token)
+        {
+            $lineno = $token->getLine();
+            $name = $this->parser->getStream()->expect(Twig_Token::NAME_TYPE)->getValue();
+            $this->parser->getStream()->expect(Twig_Token::OPERATOR_TYPE, '=');
+            $value = $this->parser->getExpressionParser()->parseExpression();
+
+            $this->parser->getStream()->expect(Twig_Token::BLOCK_END_TYPE);
+
+            return new Project_Set_Node($name, $value, $lineno, $this->getTag());
+        }
+
+        public function getTag()
+        {
+            return 'set';
+        }
+    }
+
+The ``getTag()`` method must return the tag we want to parse, here ``set``.
+
+The ``parse()`` method is invoked whenever the parser encounters a ``set``
+tag. It should return a ``Twig_Node`` instance that represents the node (the
+``Project_Set_Node`` calls creating is explained in the next section).
+
+The parsing process is simplified thanks to a bunch of methods you can call
+from the token stream (``$this->parser->getStream()``):
+
+* ``getCurrent()``: Gets the current token in the stream.
+
+* ``next()``: Moves to the next token in the stream, *but returns the old one*.
+
+* ``test($type)``, ``test($value)`` or ``test($type, $value)``: Determines whether
+  the current token is of a particular type or value (or both). The value may be an
+  array of several possible values.
+
+* ``expect($type[, $value[, $message]])``: If the current token isn't of the given
+  type/value a syntax error is thrown. Otherwise, if the type and value are correct,
+  the token is returned and the stream moves to the next token.
+
+* ``look()``: Looks a the next token without consuming it.
+
+Parsing expressions is done by calling the ``parseExpression()`` like we did for
+the ``set`` tag.
+
+.. tip::
+
+    Reading the existing ``TokenParser`` classes is the best way to learn all
+    the nitty-gritty details of the parsing process.
+
+Defining a Node
+~~~~~~~~~~~~~~~
+
+The ``Project_Set_Node`` class itself is rather simple::
+
+    class Project_Set_Node extends Twig_Node
+    {
+        public function __construct($name, Twig_Node_Expression $value, $lineno, $tag = null)
+        {
+            parent::__construct(array('value' => $value), array('name' => $name), $lineno, $tag);
+        }
+
+        public function compile(Twig_Compiler $compiler)
+        {
+            $compiler
+                ->addDebugInfo($this)
+                ->write('$context[\''.$this->getAttribute('name').'\'] = ')
+                ->subcompile($this->getNode('value'))
+                ->raw(";\n")
+            ;
+        }
+    }
+
+The compiler implements a fluid interface and provides methods that helps the
+developer generate beautiful and readable PHP code:
+
+* ``subcompile()``: Compiles a node.
+
+* ``raw()``: Writes the given string as is.
+
+* ``write()``: Writes the given string by adding indentation at the beginning
+  of each line.
+
+* ``string()``: Writes a quoted string.
+
+* ``repr()``: Writes a PHP representation of a given value (see
+  ``Twig_Node_For`` for a usage example).
+
+* ``addDebugInfo()``: Adds the line of the original template file related to
+  the current node as a comment.
+
+* ``indent()``: Indents the generated code (see ``Twig_Node_Block`` for a
+  usage example).
+
+* ``outdent()``: Outdents the generated code (see ``Twig_Node_Block`` for a
+  usage example).
+
+.. _creating_extensions:
+
+Creating an Extension
+---------------------
+
+The main motivation for writing an extension is to move often used code into a
+reusable class like adding support for internationalization. An extension can
+define tags, filters, tests, operators, global variables, functions, and node
+visitors.
+
+Creating an extension also makes for a better separation of code that is
+executed at compilation time and code needed at runtime. As such, it makes
+your code faster.
+
+Most of the time, it is useful to create a single extension for your project,
+to host all the specific tags and filters you want to add to Twig.
+
+.. tip::
+
+    When packaging your code into an extension, Twig is smart enough to
+    recompile your templates whenever you make a change to it (when the
+    ``auto_reload`` is enabled).
+
+.. note::
+
+    Before writing your own extensions, have a look at the Twig official
+    extension repository: http://github.com/fabpot/Twig-extensions.
+
+An extension is a class that implements the following interface::
+
+    interface Twig_ExtensionInterface
+    {
+        /**
+         * Initializes the runtime environment.
+         *
+         * This is where you can load some file that contains filter functions for instance.
+         *
+         * @param Twig_Environment $environment The current Twig_Environment instance
+         */
+        function initRuntime(Twig_Environment $environment);
+
+        /**
+         * Returns the token parser instances to add to the existing list.
+         *
+         * @return array An array of Twig_TokenParserInterface or Twig_TokenParserBrokerInterface instances
+         */
+        function getTokenParsers();
+
+        /**
+         * Returns the node visitor instances to add to the existing list.
+         *
+         * @return array An array of Twig_NodeVisitorInterface instances
+         */
+        function getNodeVisitors();
+
+        /**
+         * Returns a list of filters to add to the existing list.
+         *
+         * @return array An array of filters
+         */
+        function getFilters();
+
+        /**
+         * Returns a list of tests to add to the existing list.
+         *
+         * @return array An array of tests
+         */
+        function getTests();
+
+        /**
+         * Returns a list of functions to add to the existing list.
+         *
+         * @return array An array of functions
+         */
+        function getFunctions();
+
+        /**
+         * Returns a list of operators to add to the existing list.
+         *
+         * @return array An array of operators
+         */
+        function getOperators();
+
+        /**
+         * Returns a list of global variables to add to the existing list.
+         *
+         * @return array An array of global variables
+         */
+        function getGlobals();
+
+        /**
+         * Returns the name of the extension.
+         *
+         * @return string The extension name
+         */
+        function getName();
+    }
+
+To keep your extension class clean and lean, it can inherit from the built-in
+``Twig_Extension`` class instead of implementing the whole interface. That
+way, you just need to implement the ``getName()`` method as the
+``Twig_Extension`` provides empty implementations for all other methods.
+
+The ``getName()`` method must return a unique identifier for your extension.
+
+Now, with this information in mind, let's create the most basic extension
+possible::
+
+    class Project_Twig_Extension extends Twig_Extension
+    {
+        public function getName()
+        {
+            return 'project';
+        }
+    }
+
+.. note::
+
+    Of course, this extension does nothing for now. We will customize it in
+    the next sections.
+
+Twig does not care where you save your extension on the filesystem, as all
+extensions must be registered explicitly to be available in your templates.
+
+You can register an extension by using the ``addExtension()`` method on your
+main ``Environment`` object::
+
+    $twig = new Twig_Environment($loader);
+    $twig->addExtension(new Project_Twig_Extension());
+
+Of course, you need to first load the extension file by either using
+``require_once()`` or by using an autoloader (see `spl_autoload_register()`_).
+
+.. tip::
+
+    The bundled extensions are great examples of how extensions work.
+
+Globals
+~~~~~~~
+
+Global variables can be registered in an extension via the ``getGlobals()``
+method::
+
+    class Project_Twig_Extension extends Twig_Extension
+    {
+        public function getGlobals()
+        {
+            return array(
+                'text' => new Text(),
+            );
+        }
+
+        // ...
+    }
+
+Functions
+~~~~~~~~~
+
+Functions can be registered in an extension via the ``getFunctions()``
+method::
+
+    class Project_Twig_Extension extends Twig_Extension
+    {
+        public function getFunctions()
+        {
+            return array(
+                'lipsum' => new Twig_Function_Function('generate_lipsum'),
+            );
+        }
+
+        // ...
+    }
+
+Filters
+~~~~~~~
+
+To add a filter to an extension, you need to override the ``getFilters()``
+method. This method must return an array of filters to add to the Twig
+environment::
+
+    class Project_Twig_Extension extends Twig_Extension
+    {
+        public function getFilters()
+        {
+            return array(
+                'rot13' => new Twig_Filter_Function('str_rot13'),
+            );
+        }
+
+        // ...
+    }
+
+As you can see in the above code, the ``getFilters()`` method returns an array
+where keys are the name of the filters (``rot13``) and the values the
+definition of the filter (``new Twig_Filter_Function('str_rot13')``).
+
+As seen in the previous chapter, you can also define filters as static methods
+on the extension class::
+
+$twig->addFilter('rot13', new Twig_Filter_Function('Project_Twig_Extension::rot13Filter'));
+
+You can also use ``Twig_Filter_Method`` instead of ``Twig_Filter_Function``
+when defining a filter to use a method::
+
+    class Project_Twig_Extension extends Twig_Extension
+    {
+        public function getFilters()
+        {
+            return array(
+                'rot13' => new Twig_Filter_Method($this, 'rot13Filter'),
+            );
+        }
+
+        public function rot13Filter($string)
+        {
+            return str_rot13($string);
+        }
+
+        // ...
+    }
+
+The first argument of the ``Twig_Filter_Method`` constructor is always
+``$this``, the current extension object. The second one is the name of the
+method to call.
+
+Using methods for filters is a great way to package your filter without
+polluting the global namespace. This also gives the developer more flexibility
+at the cost of a small overhead.
+
+Overriding default Filters
+..........................
+
+If some default core filters do not suit your needs, you can easily override
+them by creating your own extension. Just use the same names as the one you
+want to override::
+
+    class MyCoreExtension extends Twig_Extension
+    {
+        public function getFilters()
+        {
+            return array(
+                'date' => new Twig_Filter_Method($this, 'dateFilter'),
+                // ...
+            );
+        }
+
+        public function dateFilter($timestamp, $format = 'F j, Y H:i')
+        {
+            return '...'.twig_date_format_filter($timestamp, $format);
+        }
+
+        public function getName()
+        {
+            return 'project';
+        }
+    }
+
+Here, we override the ``date`` filter with a custom one. Using this extension
+is as simple as registering the ``MyCoreExtension`` extension by calling the
+``addExtension()`` method on the environment instance::
+
+    $twig = new Twig_Environment($loader);
+    $twig->addExtension(new MyCoreExtension());
+
+Tags
+~~~~
+
+Adding a tag in an extension can be done by overriding the
+``getTokenParsers()`` method. This method must return an array of tags to add
+to the Twig environment::
+
+    class Project_Twig_Extension extends Twig_Extension
+    {
+        public function getTokenParsers()
+        {
+            return array(new Project_Set_TokenParser());
+        }
+
+        // ...
+    }
+
+In the above code, we have added a single new tag, defined by the
+``Project_Set_TokenParser`` class. The ``Project_Set_TokenParser`` class is
+responsible for parsing the tag and compiling it to PHP.
+
+Operators
+~~~~~~~~~
+
+The ``getOperators()`` methods allows to add new operators. Here is how to add
+``!``, ``||``, and ``&&`` operators::
+
+    class Project_Twig_Extension extends Twig_Extension
+    {
+        public function getOperators()
+        {
+            return array(
+                array(
+                    '!' => array('precedence' => 50, 'class' => 'Twig_Node_Expression_Unary_Not'),
+                ),
+                array(
+                    '||' => array('precedence' => 10, 'class' => 'Twig_Node_Expression_Binary_Or', 'associativity' => Twig_ExpressionParser::OPERATOR_LEFT),
+                    '&&' => array('precedence' => 15, 'class' => 'Twig_Node_Expression_Binary_And', 'associativity' => Twig_ExpressionParser::OPERATOR_LEFT),
+                ),
+            );
+        }
+
+        // ...
+    }
+
+Tests
+~~~~~
+
+The ``getTests()`` methods allows to add new test functions::
+
+    class Project_Twig_Extension extends Twig_Extension
+    {
+        public function getTests()
+        {
+            return array(
+                'even' => new Twig_Test_Function('twig_test_even'),
+            );
+        }
+
+        // ...
+    }
+
+Testing an Extension
+--------------------
+
+.. versionadded:: 1.10
+    Support for functional tests was added in Twig 1.10.
+
+Functional Tests
+~~~~~~~~~~~~~~~~
+
+You can create functional tests for extensions simply by creating the
+following file structure in your test directory::
+
+    Fixtures/
+        filters/
+            foo.test
+            bar.test
+        functions/
+            foo.test
+            bar.test
+        tags/
+            foo.test
+            bar.test
+    IntegrationTest.php
+
+The ``IntegrationTest.php`` file should look like this::
+
+    class Project_Tests_IntegrationTest extends Twig_Test_IntegrationTestCase
+    {
+        public function getExtensions()
+        {
+            return array(
+                new Project_Twig_Extension1(),
+                new Project_Twig_Extension2(),
+            );
+        }
+
+        public function getFixturesDir()
+        {
+            return dirname(__FILE__).'/Fixtures/';
+        }
+    }
+
+Fixtures examples can be found within the Twig repository
+`tests/Twig/Fixtures`_ directory.
+
+Node Tests
+~~~~~~~~~~
+
+Testing the node visitors can be complex, so extend your test cases from
+``Twig_Test_NodeTestCase``. Examples can be found in the Twig repository
+`tests/Twig/Node`_ directory.

+Twig for Developers
+===================
+
+This chapter describes the API to Twig and not the template language. It will
+be most useful as reference to those implementing the template interface to
+the application and not those who are creating Twig templates.
+
+Basics
+------
+
+Twig uses a central object called the **environment** (of class
+``Twig_Environment``). Instances of this class are used to store the
+configuration and extensions, and are used to load templates from the file
+system or other locations.
+
+Most applications will create one ``Twig_Environment`` object on application
+initialization and use that to load templates. In some cases it's however
+useful to have multiple environments side by side, if different configurations
+are in use.
+
+The simplest way to configure Twig to load templates for your application
+looks roughly like this::
+
+    require_once '/path/to/lib/Twig/Autoloader.php';
+    Twig_Autoloader::register();
+
+    $loader = new Twig_Loader_Filesystem('/path/to/templates');
+    $twig = new Twig_Environment($loader, array(
+        'cache' => '/path/to/compilation_cache',
+    ));
+
+This will create a template environment with the default settings and a loader
+that looks up the templates in the ``/path/to/templates/`` folder. Different
+loaders are available and you can also write your own if you want to load
+templates from a database or other resources.
+
+.. note::
+
+    Notice that the second argument of the environment is an array of options.
+    The ``cache`` option is a compilation cache directory, where Twig caches
+    the compiled templates to avoid the parsing phase for sub-sequent
+    requests. It is very different from the cache you might want to add for
+    the evaluated templates. For such a need, you can use any available PHP
+    cache library.
+
+To load a template from this environment you just have to call the
+``loadTemplate()`` method which then returns a ``Twig_Template`` instance::
+
+    $template = $twig->loadTemplate('index.html');
+
+To render the template with some variables, call the ``render()`` method::
+
+    echo $template->render(array('the' => 'variables', 'go' => 'here'));
+
+.. note::
+
+    The ``display()`` method is a shortcut to output the template directly.
+
+You can also load and render the template in one fell swoop::
+
+    echo $twig->render('index.html', array('the' => 'variables', 'go' => 'here'));
+
+.. _environment_options:
+
+Environment Options
+-------------------
+
+When creating a new ``Twig_Environment`` instance, you can pass an array of
+options as the constructor second argument::
+
+    $twig = new Twig_Environment($loader, array('debug' => true));
+
+The following options are available:
+
+* ``debug``: When set to ``true``, the generated templates have a
+  ``__toString()`` method that you can use to display the generated nodes
+  (default to ``false``).
+
+* ``charset``: The charset used by the templates (default to ``utf-8``).
+
+* ``base_template_class``: The base template class to use for generated
+  templates (default to ``Twig_Template``).
+
+* ``cache``: An absolute path where to store the compiled templates, or
+  ``false`` to disable caching (which is the default).
+
+* ``auto_reload``: When developing with Twig, it's useful to recompile the
+  template whenever the source code changes. If you don't provide a value for
+  the ``auto_reload`` option, it will be determined automatically based on the
+  ``debug`` value.
+
+* ``strict_variables``: If set to ``false``, Twig will silently ignore invalid
+  variables (variables and or attributes/methods that do not exist) and
+  replace them with a ``null`` value. When set to ``true``, Twig throws an
+  exception instead (default to ``false``).
+
+* ``autoescape``: If set to ``true``, auto-escaping will be enabled by default
+  for all templates (default to ``true``). As of Twig 1.8, you can set the
+  escaping strategy to use (``html``, ``js``, ``false`` to disable).
+  As of Twig 1.9, you can set the escaping strategy to use (``css``, ``url``, 
+  ``html_attr``, or a PHP callback that takes the template "filename" and must 
+  return the escaping strategy to use -- the callback cannot be a function name
+  to avoid collision with built-in escaping strategies).
+
+* ``optimizations``: A flag that indicates which optimizations to apply
+  (default to ``-1`` -- all optimizations are enabled; set it to ``0`` to
+  disable).
+
+Loaders
+-------
+
+Loaders are responsible for loading templates from a resource such as the file
+system.
+
+Compilation Cache
+~~~~~~~~~~~~~~~~~
+
+All template loaders can cache the compiled templates on the filesystem for
+future reuse. It speeds up Twig a lot as templates are only compiled once; and
+the performance boost is even larger if you use a PHP accelerator such as APC.
+See the ``cache`` and ``auto_reload`` options of ``Twig_Environment`` above
+for more information.
+
+Built-in Loaders
+~~~~~~~~~~~~~~~~
+
+Here is a list of the built-in loaders Twig provides:
+
+``Twig_Loader_Filesystem``
+..........................
+
+.. versionadded:: 1.10
+    The ``prependPath()`` and support for namespaces were added in Twig 1.10.
+
+``Twig_Loader_Filesystem`` loads templates from the file system. This loader
+can find templates in folders on the file system and is the preferred way to
+load them::
+
+    $loader = new Twig_Loader_Filesystem($templateDir);
+
+It can also look for templates in an array of directories::
+
+    $loader = new Twig_Loader_Filesystem(array($templateDir1, $templateDir2));
+
+With such a configuration, Twig will first look for templates in
+``$templateDir1`` and if they do not exist, it will fallback to look for them
+in the ``$templateDir2``.
+
+You can add or prepend paths via the ``addPath()`` and ``prependPath()``
+methods::
+
+    $loader->addPath($templateDir3);
+    $loader->prependPath($templateDir4);
+
+The filesystem loader also supports namespaced templates. This allows to group
+your templates under different namespaces which have their own template paths.
+
+When using the ``setPaths()``, ``addPath()``, and ``prependPath()`` methods,
+specify the namespace as the second argument (when not specified, these
+methods act on the "main" namespace)::
+
+    $loader->addPath($templateDir, 'admin');
+
+Namespaced templates can be accessed via the special
+``@namespace_name/template_path`` notation::
+
+    $twig->render('@admin/index.html', array());
+
+``Twig_Loader_String``
+......................
+
+``Twig_Loader_String`` loads templates from strings. It's a dummy loader as
+the template reference is the template source code::
+
+    $loader = new Twig_Loader_String();
+    $twig = new Twig_Environment($loader);
+
+    echo $twig->render('Hello {{ name }}!', array('name' => 'Fabien'));
+
+This loader should only be used for unit testing as it has severe limitations:
+several tags, like ``extends`` or ``include`` do not make sense to use as the
+reference to the template is the template source code itself.
+
+``Twig_Loader_Array``
+.....................
+
+``Twig_Loader_Array`` loads a template from a PHP array. It's passed an array
+of strings bound to template names::
+
+    $loader = new Twig_Loader_Array(array(
+        'index.html' => 'Hello {{ name }}!',
+    ));
+    $twig = new Twig_Environment($loader);
+
+    echo $twig->render('index.html', array('name' => 'Fabien'));
+
+This loader is very useful for unit testing. It can also be used for small
+projects where storing all templates in a single PHP file might make sense.
+
+.. tip::
+
+    When using the ``Array`` or ``String`` loaders with a cache mechanism, you
+    should know that a new cache key is generated each time a template content
+    "changes" (the cache key being the source code of the template). If you
+    don't want to see your cache grows out of control, you need to take care
+    of clearing the old cache file by yourself.
+
+``Twig_Loader_Chain``
+.....................
+
+``Twig_Loader_Chain`` delegates the loading of templates to other loaders::
+
+    $loader1 = new Twig_Loader_Array(array(
+        'base.html' => '{% block content %}{% endblock %}',
+    ));
+    $loader2 = new Twig_Loader_Array(array(
+        'index.html' => '{% extends "base.twig" %}{% block content %}Hello {{ name }}{% endblock %}',
+        'base.html'  => 'Will never be loaded',
+    ));
+
+    $loader = new Twig_Loader_Chain(array($loader1, $loader2));
+
+    $twig = new Twig_Environment($loader);
+
+When looking for a template, Twig will try each loader in turn and it will
+return as soon as the template is found. When rendering the ``index.html``
+template from the above example, Twig will load it with ``$loader2`` but the
+``base.html`` template will be loaded from ``$loader1``.
+
+``Twig_Loader_Chain`` accepts any loader that implements
+``Twig_LoaderInterface``.
+
+.. note::
+
+    You can also add loaders via the ``addLoader()`` method.
+
+Create your own Loader
+~~~~~~~~~~~~~~~~~~~~~~
+
+All loaders implement the ``Twig_LoaderInterface``::
+
+    interface Twig_LoaderInterface
+    {
+        /**
+         * Gets the source code of a template, given its name.
+         *
+         * @param  string $name string The name of the template to load
+         *
+         * @return string The template source code
+         */
+        function getSource($name);
+
+        /**
+         * Gets the cache key to use for the cache for a given template name.
+         *
+         * @param  string $name string The name of the template to load
+         *
+         * @return string The cache key
+         */
+        function getCacheKey($name);
+
+        /**
+         * Returns true if the template is still fresh.
+         *
+         * @param string    $name The template name
+         * @param timestamp $time The last modification time of the cached template
+         */
+        function isFresh($name, $time);
+    }
+
+As an example, here is how the built-in ``Twig_Loader_String`` reads::
+
+    class Twig_Loader_String implements Twig_LoaderInterface
+    {
+        public function getSource($name)
+        {
+          return $name;
+        }
+
+        public function getCacheKey($name)
+        {
+          return $name;
+        }
+
+        public function isFresh($name, $time)
+        {
+          return false;
+        }
+    }
+
+The ``isFresh()`` method must return ``true`` if the current cached template
+is still fresh, given the last modification time, or ``false`` otherwise.
+
+.. tip::
+
+    As of Twig 1.11.0, you can also implement ``Twig_ExistsLoaderInterface``
+    to make your loader faster when used with the chain loader.
+
+Using Extensions
+----------------
+
+Twig extensions are packages that add new features to Twig. Using an
+extension is as simple as using the ``addExtension()`` method::
+
+    $twig->addExtension(new Twig_Extension_Sandbox());
+
+Twig comes bundled with the following extensions:
+
+* *Twig_Extension_Core*: Defines all the core features of Twig.
+
+* *Twig_Extension_Escaper*: Adds automatic output-escaping and the possibility
+  to escape/unescape blocks of code.
+
+* *Twig_Extension_Sandbox*: Adds a sandbox mode to the default Twig
+  environment, making it safe to evaluate untrusted code.
+
+* *Twig_Extension_Optimizer*: Optimizes the node tree before compilation.
+
+The core, escaper, and optimizer extensions do not need to be added to the
+Twig environment, as they are registered by default.
+
+Built-in Extensions
+-------------------
+
+This section describes the features added by the built-in extensions.
+
+.. tip::
+
+    Read the chapter about extending Twig to learn how to create your own
+    extensions.
+
+Core Extension
+~~~~~~~~~~~~~~
+
+The ``core`` extension defines all the core features of Twig:
+
+* :doc:`Tags <tags/index>`;
+* :doc:`Filters <filters/index>`;
+* :doc:`Functions <functions/index>`;
+* :doc:`Tests <tests/index>`.
+
+Escaper Extension
+~~~~~~~~~~~~~~~~~
+
+The ``escaper`` extension adds automatic output escaping to Twig. It defines a
+tag, ``autoescape``, and a filter, ``raw``.
+
+When creating the escaper extension, you can switch on or off the global
+output escaping strategy::
+
+    $escaper = new Twig_Extension_Escaper('html');
+    $twig->addExtension($escaper);
+
+If set to ``html``, all variables in templates are escaped (using the ``html``
+escaping strategy), except those using the ``raw`` filter:
+
+.. code-block:: jinja
+
+    {{ article.to_html|raw }}
+
+You can also change the escaping mode locally by using the ``autoescape`` tag
+(see the :doc:`autoescape<tags/autoescape>` doc for the syntax used before
+Twig 1.8):
+
+.. code-block:: jinja
+
+    {% autoescape 'html' %}
+        {{ var }}
+        {{ var|raw }}      {# var won't be escaped #}
+        {{ var|escape }}   {# var won't be double-escaped #}
+    {% endautoescape %}
+
+.. warning::
+
+    The ``autoescape`` tag has no effect on included files.
+
+The escaping rules are implemented as follows:
+
+* Literals (integers, booleans, arrays, ...) used in the template directly as
+  variables or filter arguments are never automatically escaped:
+
+  .. code-block:: jinja
+
+        {{ "Twig<br />" }} {# won't be escaped #}
+
+        {% set text = "Twig<br />" %}
+        {{ text }} {# will be escaped #}
+
+* Expressions which the result is always a literal or a variable marked safe
+  are never automatically escaped:
+
+  .. code-block:: jinja
+
+        {{ foo ? "Twig<br />" : "<br />Twig" }} {# won't be escaped #}
+
+        {% set text = "Twig<br />" %}
+        {{ foo ? text : "<br />Twig" }} {# will be escaped #}
+
+        {% set text = "Twig<br />" %}
+        {{ foo ? text|raw : "<br />Twig" }} {# won't be escaped #}
+
+        {% set text = "Twig<br />" %}
+        {{ foo ? text|escape : "<br />Twig" }} {# the result of the expression won't be escaped #}
+
+* Escaping is applied before printing, after any other filter is applied:
+
+  .. code-block:: jinja
+
+        {{ var|upper }} {# is equivalent to {{ var|upper|escape }} #}
+
+* The `raw` filter should only be used at the end of the filter chain:
+
+  .. code-block:: jinja
+
+        {{ var|raw|upper }} {# will be escaped #}
+
+        {{ var|upper|raw }} {# won't be escaped #}
+
+* Automatic escaping is not applied if the last filter in the chain is marked
+  safe for the current context (e.g. ``html`` or ``js``). ``escaper`` and
+  ``escaper('html')`` are marked safe for html, ``escaper('js')`` is marked
+  safe for javascript, ``raw`` is marked safe for everything.
+
+  .. code-block:: jinja
+
+        {% autoescape 'js' %}
+            {{ var|escape('html') }} {# will be escaped for html and javascript #}
+            {{ var }} {# will be escaped for javascript #}
+            {{ var|escape('js') }} {# won't be double-escaped #}
+        {% endautoescape %}
+
+.. note::
+
+    Note that autoescaping has some limitations as escaping is applied on
+    expressions after evaluation. For instance, when working with
+    concatenation, ``{{ foo|raw ~ bar }}`` won't give the expected result as
+    escaping is applied on the result of the concatenation, not on the
+    individual variables (so, the ``raw`` filter won't have any effect here).
+
+Sandbox Extension
+~~~~~~~~~~~~~~~~~
+
+The ``sandbox`` extension can be used to evaluate untrusted code. Access to
+unsafe attributes and methods is prohibited. The sandbox security is managed
+by a policy instance. By default, Twig comes with one policy class:
+``Twig_Sandbox_SecurityPolicy``. This class allows you to white-list some
+tags, filters, properties, and methods::
+
+    $tags = array('if');
+    $filters = array('upper');
+    $methods = array(
+        'Article' => array('getTitle', 'getBody'),
+    );
+    $properties = array(
+        'Article' => array('title', 'body'),
+    );
+    $functions = array('range');
+    $policy = new Twig_Sandbox_SecurityPolicy($tags, $filters, $methods, $properties, $functions);
+
+With the previous configuration, the security policy will only allow usage of
+the ``if`` tag, and the ``upper`` filter. Moreover, the templates will only be
+able to call the ``getTitle()`` and ``getBody()`` methods on ``Article``
+objects, and the ``title`` and ``body`` public properties. Everything else
+won't be allowed and will generate a ``Twig_Sandbox_SecurityError`` exception.
+
+The policy object is the first argument of the sandbox constructor::
+
+    $sandbox = new Twig_Extension_Sandbox($policy);
+    $twig->addExtension($sandbox);
+
+By default, the sandbox mode is disabled and should be enabled when including
+untrusted template code by using the ``sandbox`` tag:
+
+.. code-block:: jinja
+
+    {% sandbox %}
+        {% include 'user.html' %}
+    {% endsandbox %}
+
+You can sandbox all templates by passing ``true`` as the second argument of
+the extension constructor::
+
+    $sandbox = new Twig_Extension_Sandbox($policy, true);
+
+Optimizer Extension
+~~~~~~~~~~~~~~~~~~~
+
+The ``optimizer`` extension optimizes the node tree before compilation::
+
+    $twig->addExtension(new Twig_Extension_Optimizer());
+
+By default, all optimizations are turned on. You can select the ones you want
+to enable by passing them to the constructor::
+
+    $optimizer = new Twig_Extension_Optimizer(Twig_NodeVisitor_Optimizer::OPTIMIZE_FOR);
+
+    $twig->addExtension($optimizer);
+
+Twig supports the following optimizations:
+
+* ``Twig_NodeVisitor_Optimizer::OPTIMIZE_ALL``, enables all optimizations
+  (this is the default value).
+* ``Twig_NodeVisitor_Optimizer::OPTIMIZE_NONE``, disables all optimizations.
+  This reduces the compilation time, but it can increase the execution time
+  and the consumed memory.
+* ``Twig_NodeVisitor_Optimizer::OPTIMIZE_FOR``, optimizes the ``for`` tag by
+  removing the ``loop`` variable creation whenever possible.
+* ``Twig_NodeVisitor_Optimizer::OPTIMIZE_RAW_FILTER``, removes the ``raw``
+  filter whenever possible.
+* ``Twig_NodeVisitor_Optimizer::OPTIMIZE_VAR_ACCESS``, simplifies the creation
+  and access of variables in the compiled templates whenever possible.
+
+Exceptions
+----------
+
+Twig can throw exceptions:
+
+* ``Twig_Error``: The base exception for all errors.
+
+* ``Twig_Error_Syntax``: Thrown to tell the user that there is a problem with
+  the template syntax.
+
+* ``Twig_Error_Runtime``: Thrown when an error occurs at runtime (when a filter
+  does not exist for instance).
+
+* ``Twig_Error_Loader``: Thrown when an error occurs during template loading.
+
+* ``Twig_Sandbox_SecurityError``: Thrown when an unallowed tag, filter, or
+  method is called in a sandboxed template.

+Coding Standards
+================
+
+When writing Twig templates, we recommend you to follow these official coding
+standards:
+
+* Put one (and only one) space after the start of a delimiter (``{{``, ``{%``,
+  and ``{#``) and before the end of a delimiter (``}}``, ``%}``, and ``#}``):
+
+  .. code-block:: jinja
+
+    {{ foo }}
+    {# comment #}
+    {% if foo %}{% endif %}
+
+  When using the whitespace control character, do not put any spaces between
+  it and the delimiter:
+
+  .. code-block:: jinja
+
+    {{- foo -}}
+    {#- comment -#}
+    {%- if foo -%}{%- endif -%}
+
+* Put one (and only one) space before and after the following operators:
+  comparison operators (``==``, ``!=``, ``<``, ``>``, ``>=``, ``<=``), math
+  operators (``+``, ``-``, ``/``, ``*``, ``%``, ``//``, ``**``), logic
+  operators (``not``, ``and``, ``or``), ``~``, ``is``, ``in``, and the ternary
+  operator (``?:``):
+
+  .. code-block:: jinja
+
+     {{ 1 + 2 }}
+     {{ foo ~ bar }}
+     {{ true ? true : false }}
+
+* Put one (and only one) space after the ``:`` sign in hashes and ``,`` in
+  arrays and hashes:
+
+  .. code-block:: jinja
+
+     {{ [1, 2, 3] }}
+     {{ {'foo': 'bar'} }}
+
+* Do not put any spaces after an opening parenthesis and before a closing
+  parenthesis in expressions:
+
+  .. code-block:: jinja
+
+    {{ 1 + (2 * 3) }}
+
+* Do not put any spaces before and after string delimiters:
+
+  .. code-block:: jinja
+
+    {{ 'foo' }}
+    {{ "foo" }}
+
+* Do not put any spaces before and after the following operators: ``|``,
+  ``.``, ``..``, ``[]``:
+
+  .. code-block:: jinja
+
+    {{ foo|upper|lower }}
+    {{ user.name }}
+    {{ user[name] }}
+    {% for i in 1..12 %}{% endfor %}
+
+* Do not put any spaces before and after the parenthesis used for filter and
+  function calls:
+
+  .. code-block:: jinja
+
+     {{ foo|default('foo') }}
+     {{ range(1..10) }}
+
+* Do not put any spaces before and after the opening and the closing of arrays
+  and hashes:
+
+  .. code-block:: jinja
+
+     {{ [1, 2, 3] }}
+     {{ {'foo': 'bar'} }}
+
+* Use lower cased and underscored variable names:
+
+  .. code-block:: jinja
+
+     {% set foo = 'foo' %}
+     {% set foo_bar = 'foo' %}
+
+* Indent your code inside tags (use the same indentation as the one used for
+  the main language of the file):
+
+  .. code-block:: jinja
+
+     {% block foo %}
+        {% if true %}
+            true
+        {% endif %}
+     {% endblock %}

+Deprecated Features
+===================
+
+This document lists all deprecated features in Twig. Deprecated features are
+kept for backward compatibility and removed in the next major release (a
+feature that was deprecated in Twig 1.x is removed in Twig 2.0).
+
+Token Parsers
+-------------
+
+* As of Twig 1.x, the token parser broker sub-system is deprecated. The

+  * ``Twig_TokenParserBroker``
+
+Extensions
+----------
+
+* As of Twig 1.x, the ability to remove an extension is deprecated and the
+  ``Twig_Environment::removeExtension()`` method will be removed in 2.0.
+
+PEAR
+----
+
+PEAR support will be discontinued in Twig 2.0, and no PEAR packages will be
+provided. Use Composer instead.
+
+Filters

+  * ``Twig_Filter_Method``
+  * ``Twig_Filter_Node``
+
+* As of Twig 2.x, the ``Twig_SimpleFilter`` class is deprecated and will be
+  removed in Twig 3.x (use ``Twig_Filter`` instead). In Twig 2.x,
+  ``Twig_SimpleFilter`` is just an alias for ``Twig_Filter``.
+
+Functions
+---------
+
+* As of Twig 1.x, use ``Twig_SimpleFunction`` to add a function. The following
+  classes and interfaces will be removed in 2.0:

+  be removed in Twig 3.0):
+
+* ``Twig_CompilerInterface``     (use ``Twig_Compiler`` instead)
+* ``Twig_LexerInterface``        (use ``Twig_Lexer`` instead)
+* ``Twig_NodeInterface``         (use ``Twig_Node`` instead)
+* ``Twig_ParserInterface``       (use ``Twig_Parser`` instead)
+* ``Twig_ExistsLoaderInterface`` (merged with ``Twig_LoaderInterface``)
+* ``Twig_TemplateInterface``     (use ``Twig_Template`` instead)
+
+Globals

+``convert_encoding``
+====================
+
+.. versionadded:: 1.4
+    The ``convert_encoding`` filter was added in Twig 1.4.
+
+The ``convert_encoding`` filter converts a string from one encoding to
+another. The first argument is the expected output charset and the second one
+is the input charset:
+
+.. code-block:: jinja
+
+    {{ data|convert_encoding('UTF-8', 'iso-2022-jp') }}
+
+.. note::
+
+    This filter relies on the `iconv`_ or `mbstring`_ extension, so one of
+    them must be installed. In case both are installed, `mbstring`_ is used by
+    default (Twig before 1.8.1 uses `iconv`_ by default).
+
+Arguments
+---------
+

+ * ``to``:   The output charset
+
+.. _`iconv`:    http://php.net/iconv
+.. _`mbstring`: http://php.net/mbstring

+========

+    The default date format support has been added in Twig 1.5.
+
+.. versionadded:: 1.6.1
+    The default timezone support has been added in Twig 1.6.1.
+
+.. versionadded:: 1.11.0
+    The introduction of the false value for the timezone was introduced in Twig 1.11.0
+
+The ``date`` filter formats a date to a given format:
+
+.. code-block:: jinja
+
+    {{ post.published_at|date("m/d/Y") }}
+
+The ``date`` filter accepts strings (it must be in a format supported by the
+`strtotime`_ function), `DateTime`_ instances, or `DateInterval`_ instances. For
+instance, to display the current date, filter the word "now":
+
+.. code-block:: jinja
+
+    {{ "now"|date("m/d/Y") }}
+
+To escape words and characters in the date format use ``\\`` in front of each
+character:
+
+.. code-block:: jinja
+
+    {{ post.published_at|date("F jS \\a\\t g:ia") }}
+
+If the value passed to the ``date`` filter is ``null``, it will return the
+current date by default. If an empty string is desired instead of the current
+date, use a ternary operator:
+
+.. code-block:: jinja
+
+    {{ post.published_at is empty ? "" : post.published_at|date("m/d/Y") }}
+
+If no format is provided, Twig will use the default one: ``F j, Y H:i``. This
+default can be easily changed by calling the ``setDateFormat()`` method on the
+``core`` extension instance. The first argument is the default format for
+dates and the second one is the default format for date intervals:
+
+.. code-block:: php
+
+    $twig = new Twig_Environment($loader);
+    $twig->getExtension('core')->setDateFormat('d/m/Y', '%d days');
+
+Timezone
+--------
+
+By default, the date is displayed by applying the default timezone (the one
+specified in php.ini or declared in Twig -- see below), but you can override
+it by explicitly specifying a timezone:
+
+.. code-block:: jinja
+
+    {{ post.published_at|date("m/d/Y", "Europe/Paris") }}
+
+If the date is already a DateTime object, and if you want to keep its current
+timezone, pass ``false`` as the timezone value:
+
+.. code-block:: jinja
+
+    {{ post.published_at|date("m/d/Y", false) }}
+
+The default timezone can also be set globally by calling ``setTimezone()``:
+
+.. code-block:: php
+
+    $twig = new Twig_Environment($loader);
+    $twig->getExtension('core')->setTimezone('Europe/Paris');
+

+``escape``
+==========
+
+.. versionadded:: 1.9.0
+    The ``css``, ``url``, and ``html_attr`` strategies were added in Twig
+    1.9.0.
+
+The ``escape`` filter escapes a string for safe insertion into the final
+output. It supports different escaping strategies depending on the template
+context.
+
+By default, it uses the HTML escaping strategy:
+
+.. code-block:: jinja
+
+    {{ user.username|escape }}
+
+For convenience, the ``e`` filter is defined as an alias:
+
+.. code-block:: jinja
+
+    {{ user.username|e }}
+
+The ``escape`` filter can also be used in other contexts than HTML thanks to
+an optional argument which defines the escaping strategy to use:
+
+.. code-block:: jinja
+
+    {{ user.username|e }}
+    {# is equivalent to #}
+    {{ user.username|e('html') }}
+
+And here is how to escape variables included in JavaScript code:
+
+.. code-block:: jinja
+
+    {{ user.username|escape('js') }}
+    {{ user.username|e('js') }}
+
+The ``escape`` filter supports the following escaping strategies:
+
+* ``html``: escapes a string for the **HTML body** context.
+
+* ``js``: escapes a string for the **JavaScript context**.
+
+* ``css``: escapes a string for the **CSS context**. CSS escaping can be
+  applied to any string being inserted into CSS and escapes everything except
+  alphanumerics.
+
+* ``url``: escapes a string for the **URI or parameter contexts**. This should
+  not be used to escape an entire URI; only a subcomponent being inserted.
+
+* ``html_attr``: escapes a string for the **HTML attribute** context.
+
+.. note::
+
+    Internally, ``escape`` uses the PHP native `htmlspecialchars`_ function
+    for the HTML escaping strategy.
+
+.. caution::
+
+    When using automatic escaping, Twig tries to not double-escape a variable
+    when the automatic escaping strategy is the same as the one applied by the
+    escape filter; but that does not work when using a variable as the
+    escaping strategy:
+
+    .. code-block:: jinja
+
+        {% set strategy = 'html' %}
+
+        {% autoescape 'html' %}
+            {{ var|escape('html') }}   {# won't be double-escaped #}
+            {{ var|escape(strategy) }} {# will be double-escaped #}
+        {% endautoescape %}
+
+    When using a variable as the escaping strategy, you should disable
+    automatic escaping:
+
+    .. code-block:: jinja
+
+        {% set strategy = 'html' %}
+
+        {% autoescape 'html' %}
+            {{ var|escape(strategy)|raw }} {# won't be double-escaped #}
+        {% endautoescape %}

+``number_format``
+=================
+
+.. versionadded:: 1.5
+    The number_format filter was added in Twig 1.5
+
+The ``number_format`` filter formats numbers.  It is a wrapper around PHP's
+`number_format`_ function:
+
+.. code-block:: jinja
+
+    {{ 200.35|number_format }}
+
+You can control the number of decimal places, decimal point, and thousands
+separator using the additional arguments:
+
+.. code-block:: jinja
+
+    {{ 9800.333|number_format(2, '.', ',') }}
+
+If no formatting options are provided then Twig will use the default formatting
+options of:
+
+- 0 decimal places.
+- ``.`` as the decimal point.
+- ``,`` as the thousands separator.
+
+These defaults can be easily changed through the core extension:
+
+.. code-block:: php
+
+    $twig = new Twig_Environment($loader);
+    $twig->getExtension('core')->setNumberFormat(3, '.', ',');
+
+The defaults set for ``number_format`` can be over-ridden upon each call using the
+additional parameters.
+
+Arguments
+---------
+
+ * ``decimal``:       The number of decimal points to display
+ * ``decimal_point``: The character(s) to use for the decimal point
+ * ``decimal_sep``:   The character(s) to use for the thousands separator

+``slice``
+===========
+
+.. versionadded:: 1.6
+    The slice filter was added in Twig 1.6.
+
+The ``slice`` filter extracts a slice of a sequence, a mapping, or a string:
+
+.. code-block:: jinja
+
+    {% for i in [1, 2, 3, 4, 5]|slice(1, 2) %}
+        {# will iterate over 2 and 3 #}
+    {% endfor %}
+
+    {{ '12345'|slice(1, 2) }}
+
+    {# outputs 23 #}
+
+You can use any valid expression for both the start and the length:
+
+.. code-block:: jinja
+
+    {% for i in [1, 2, 3, 4, 5]|slice(start, length) %}
+        {# ... #}
+    {% endfor %}
+
+As syntactic sugar, you can also use the ``[]`` notation:
+
+.. code-block:: jinja
+
+    {% for i in [1, 2, 3, 4, 5][start:length] %}
+        {# ... #}

+
+    {# you can omit the last argument -- which will select everything till the end #}
+    {{ '12345'[2:] }} {# will display "345" #}
+
+The ``slice`` filter works as the `array_slice`_ PHP function for arrays and
+`substr`_ for strings.
+
+If the start is non-negative, the sequence will start at that start in the
+variable. If start is negative, the sequence will start that far from the end
+of the variable.
+
+If length is given and is positive, then the sequence will have up to that
+many elements in it. If the variable is shorter than the length, then only the
+available variable elements will be present. If length is given and is
+negative then the sequence will stop that many elements from the end of the
+variable. If it is omitted, then the sequence will have everything from offset
+up until the end of the variable.
+
+.. note::
+
+    It also works with objects implementing the `Traversable`_ interface.
+

+``dump``
+========
+
+.. versionadded:: 1.5
+    The dump function was added in Twig 1.5.
+
+The ``dump`` function dumps information about a template variable. This is
+mostly useful to debug a template that does not behave as expected by
+introspecting its variables:
+
+.. code-block:: jinja
+
+    {{ dump(user) }}
+
+.. note::
+
+    The ``dump`` function is not available by default. You must add the
+    ``Twig_Extension_Debug`` extension explicitly when creating your Twig
+    environment::
+
+        $twig = new Twig_Environment($loader, array(
+            'debug' => true,
+            // ...
+        ));
+        $twig->addExtension(new Twig_Extension_Debug());
+
+    Even when enabled, the ``dump`` function won't display anything if the
+    ``debug`` option on the environment is not enabled (to avoid leaking debug
+    information on a production server).
+
+In an HTML context, wrap the output with a ``pre`` tag to make it easier to
+read:
+
+.. code-block:: jinja
+
+    <pre>
+        {{ dump(user) }}
+    </pre>
+
+.. tip::
+
+    Using a ``pre`` tag is not needed when `XDebug`_ is enabled and
+    ``html_errors`` is ``on``; as a bonus, the output is also nicer with
+    XDebug enabled.
+
+You can debug several variables by passing them as additional arguments:
+
+.. code-block:: jinja
+
+    {{ dump(user, categories) }}
+
+If you don't pass any value, all variables from the current context are
+dumped:
+
+.. code-block:: jinja
+
+    {{ dump() }}
+
+.. note::
+
+    Internally, Twig uses the PHP `var_dump`_ function.
+
+Arguments

+``include``
+===========
+
+.. versionadded:: 1.12
+    The include function was added in Twig 1.12.
+
+The ``include`` function returns the rendered content of a template:
+
+.. code-block:: jinja
+
+    {{ include('template.html') }}
+    {{ include(some_var) }}
+
+Included templates have access to the variables of the active context.
+
+If you are using the filesystem loader, the templates are looked for in the
+paths defined by it.
+
+The context is passed by default to the template but you can also pass
+additional variables:
+
+.. code-block:: jinja
+
+    {# template.html will have access to the variables from the current context and the additional ones provided #}
+    {{ include('template.html', {foo: 'bar'}) }}
+
+You can disable access to the context by setting ``with_context`` to
+``false``:
+
+.. code-block:: jinja
+
+    {# only the foo variable will be accessible #}
+    {{ include('template.html', {foo: 'bar'}, with_context = false) }}
+
+.. code-block:: jinja
+
+    {# no variables will be accessible #}
+    {{ include('template.html', with_context = false) }}
+
+And if the expression evaluates to a ``Twig_Template`` object, Twig will use it
+directly::
+
+    // {{ include(template) }}
+
+    $template = $twig->loadTemplate('some_template.twig');
+
+    $twig->loadTemplate('template.twig')->display(array('template' => $template));
+
+When you set the ``ignore_missing`` flag, Twig will return an empty string if
+the template does not exist:
+
+.. code-block:: jinja
+
+    {{ include('sidebar.html', ignore_missing = true) }}
+
+You can also provide a list of templates that are checked for existence before
+inclusion. The first template that exists will be rendered:
+
+.. code-block:: jinja
+
+    {{ include(['page_detailed.html', 'page.html']) }}
+
+If ``ignore_missing`` is set, it will fall back to rendering nothing if none
+of the templates exist, otherwise it will throw an exception.
+
+When including a template created by an end user, you should consider
+sandboxing it:
+
+.. code-block:: jinja
+
+    {{ include('page.html', sandboxed = true) }}
+
+Arguments
+---------
+
+ * ``template``:       The template to render
+ * ``variables``:      The variables to pass to the template
+ * ``with_context``:   Whether to pass the current context variables or not
+ * ``ignore_missing``: Whether to ignore missing templates or not
+ * ``sandboxed``:      Whether to sandbox the template or not

+Twig Internals
+==============
+
+Twig is very extensible and you can easily hack it. Keep in mind that you
+should probably try to create an extension before hacking the core, as most
+features and enhancements can be done with extensions. This chapter is also
+useful for people who want to understand how Twig works under the hood.
+
+How Twig works?
+---------------
+
+The rendering of a Twig template can be summarized into four key steps:
+
+* **Load** the template: If the template is already compiled, load it and go
+  to the *evaluation* step, otherwise:
+
+  * First, the **lexer** tokenizes the template source code into small pieces
+    for easier processing;
+  * Then, the **parser** converts the token stream into a meaningful tree
+    of nodes (the Abstract Syntax Tree);
+  * Eventually, the *compiler* transforms the AST into PHP code;
+
+* **Evaluate** the template: It basically means calling the ``display()``
+  method of the compiled template and passing it the context.
+
+The Lexer
+---------
+
+The lexer tokenizes a template source code into a token stream (each token is
+an instance of ``Twig_Token``, and the stream is an instance of
+``Twig_TokenStream``). The default lexer recognizes 13 different token types:
+
+* ``Twig_Token::BLOCK_START_TYPE``, ``Twig_Token::BLOCK_END_TYPE``: Delimiters for blocks (``{% %}``)
+* ``Twig_Token::VAR_START_TYPE``, ``Twig_Token::VAR_END_TYPE``: Delimiters for variables (``{{ }}``)
+* ``Twig_Token::TEXT_TYPE``: A text outside an expression;
+* ``Twig_Token::NAME_TYPE``: A name in an expression;
+* ``Twig_Token::NUMBER_TYPE``: A number in an expression;
+* ``Twig_Token::STRING_TYPE``: A string in an expression;
+* ``Twig_Token::OPERATOR_TYPE``: An operator;
+* ``Twig_Token::PUNCTUATION_TYPE``: A punctuation sign;
+* ``Twig_Token::INTERPOLATION_START_TYPE``, ``Twig_Token::INTERPOLATION_END_TYPE`` (as of Twig 1.5): Delimiters for string interpolation;
+* ``Twig_Token::EOF_TYPE``: Ends of template.
+
+You can manually convert a source code into a token stream by calling the
+``tokenize()`` of an environment::
+
+    $stream = $twig->tokenize($source, $identifier);
+
+As the stream has a ``__toString()`` method, you can have a textual
+representation of it by echoing the object::
+
+    echo $stream."\n";
+
+Here is the output for the ``Hello {{ name }}`` template:
+
+.. code-block:: text
+
+    TEXT_TYPE(Hello )
+    VAR_START_TYPE()
+    NAME_TYPE(name)
+    VAR_END_TYPE()
+    EOF_TYPE()
+
+.. note::
+
+    You can change the default lexer use by Twig (``Twig_Lexer``) by calling
+    the ``setLexer()`` method::
+
+        $twig->setLexer($lexer);
+
+The Parser
+----------
+
+The parser converts the token stream into an AST (Abstract Syntax Tree), or a
+node tree (an instance of ``Twig_Node_Module``). The core extension defines
+the basic nodes like: ``for``, ``if``, ... and the expression nodes.
+
+You can manually convert a token stream into a node tree by calling the
+``parse()`` method of an environment::
+
+    $nodes = $twig->parse($stream);
+
+Echoing the node object gives you a nice representation of the tree::
+
+    echo $nodes."\n";
+
+Here is the output for the ``Hello {{ name }}`` template:
+
+.. code-block:: text
+
+    Twig_Node_Module(
+      Twig_Node_Text(Hello )
+      Twig_Node_Print(
+        Twig_Node_Expression_Name(name)
+      )
+    )
+
+.. note::
+
+    The default parser (``Twig_TokenParser``) can be also changed by calling the
+    ``setParser()`` method::
+
+        $twig->setParser($parser);
+
+The Compiler
+------------
+
+The last step is done by the compiler. It takes a node tree as an input and
+generates PHP code usable for runtime execution of the template.
+
+You can call the compiler by hand with the ``compile()`` method of an
+environment::
+
+    $php = $twig->compile($nodes);
+
+The ``compile()`` method returns the PHP source code representing the node.
+
+The generated template for a ``Hello {{ name }}`` template reads as follows
+(the actual output can differ depending on the version of Twig you are
+using)::
+
+    /* Hello {{ name }} */
+    class __TwigTemplate_1121b6f109fe93ebe8c6e22e3712bceb extends Twig_Template
+    {
+        protected function doDisplay(array $context, array $blocks = array())
+        {
+            // line 1
+            echo "Hello ";
+            echo twig_escape_filter($this->env, $this->getContext($context, "name"), "ndex", null, true);
+        }
+
+        // some more code
+    }
+
+.. note::
+
+    As for the lexer and the parser, the default compiler (``Twig_Compiler``) can
+    be changed by calling the ``setCompiler()`` method::
+
+        $twig->setCompiler($compiler);

+Introduction
+============
+
+This is the documentation for Twig, the flexible, fast, and secure template
+engine for PHP.
+
+If you have any exposure to other text-based template languages, such as
+Smarty, Django, or Jinja, you should feel right at home with Twig. It's both
+designer and developer friendly by sticking to PHP's principles and adding
+functionality useful for templating environments.
+
+The key-features are...
+
+* *Fast*: Twig compiles templates down to plain optimized PHP code. The
+  overhead compared to regular PHP code was reduced to the very minimum.
+
+* *Secure*: Twig has a sandbox mode to evaluate untrusted template code. This
+  allows Twig to be used as a template language for applications where users
+  may modify the template design.
+
+* *Flexible*: Twig is powered by a flexible lexer and parser. This allows the
+  developer to define its own custom tags and filters, and create its own DSL.
+
+Prerequisites
+-------------
+
+Twig needs at least **PHP 5.2.4** to run.
+
+Installation
+------------
+
+You have multiple ways to install Twig.
+
+Installing via Composer (recommended)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+1. Install composer in your project:
+
+.. code-block:: bash
+
+    curl -s http://getcomposer.org/installer | php
+
+2. Create a ``composer.json`` file in your project root:
+
+.. code-block:: javascript
+
+    {
+        "require": {
+            "twig/twig": "1.*"
+        }
+    }
+
+3. Install via composer
+
+.. code-block:: bash
+
+    php composer.phar install
+
+.. note::
+    If you want to learn more about Composer, the ``composer.json`` file syntax
+    and its usage, you can read the `online documentation`_.
+
+Installing from the tarball release
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+1. Download the most recent tarball from the `download page`_
+2. Unpack the tarball
+3. Move the files somewhere in your project
+
+Installing the development version
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+1. Install Git
+2. ``git clone git://github.com/fabpot/Twig.git``
+
+Installing the PEAR package
+~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+1. Install PEAR
+2. ``pear channel-discover pear.twig-project.org``
+3. ``pear install twig/Twig`` (or ``pear install twig/Twig-beta``)
+
+
+Installing the C extension
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+.. versionadded:: 1.4
+    The C extension was added in Twig 1.4.
+
+Twig comes with a C extension that enhances the performance of the Twig
+runtime engine. You can install it like any other PHP extension:
+
+.. code-block:: bash
+
+    $ cd ext/twig
+    $ phpize
+    $ ./configure
+    $ make
+    $ make install
+
+Finally, enable the extension in your ``php.ini`` configuration file:
+
+.. code-block:: ini
+
+    extension=twig.so
+
+And from now on, Twig will automatically compile your templates to take
+advantage of the C extension. Note that this extension does not replace the
+PHP code but only provides an optimized version of the
+``Twig_Template::getAttribute()`` method.
+
+.. tip::
+
+    On Windows, you can also simply download and install a `pre-built DLL`_.
+
+Basic API Usage
+---------------
+
+This section gives you a brief introduction to the PHP API for Twig.
+
+The first step to use Twig is to register its autoloader::
+
+    require_once '/path/to/lib/Twig/Autoloader.php';
+    Twig_Autoloader::register();
+
+Replace the ``/path/to/lib/`` path with the path you used for Twig
+installation.
+
+If you have installed Twig via Composer you can take advantage of Composer's
+autoload mechanism by replacing the previous snippet for::

+
+Twig uses a loader (``Twig_Loader_String``) to locate templates, and an
+environment (``Twig_Environment``) to store the configuration.
+
+The ``render()`` method loads the template passed as a first argument and
+renders it with the variables passed as a second argument.
+
+As templates are generally stored on the filesystem, Twig also comes with a
+filesystem loader::
+
+    $loader = new Twig_Loader_Filesystem('/path/to/templates');
+    $twig = new Twig_Environment($loader, array(
+        'cache' => '/path/to/compilation_cache',
+    ));
+

+Recipes
+=======
+
+Making a Layout conditional
+---------------------------
+
+Working with Ajax means that the same content is sometimes displayed as is,
+and sometimes decorated with a layout. As Twig layout template names can be
+any valid expression, you can pass a variable that evaluates to ``true`` when
+the request is made via Ajax and choose the layout accordingly:
+
+.. code-block:: jinja
+
+    {% extends request.ajax ? "base_ajax.html" : "base.html" %}
+
+    {% block content %}
+        This is the content to be displayed.
+    {% endblock %}
+
+Making an Include dynamic
+-------------------------
+
+When including a template, its name does not need to be a string. For
+instance, the name can depend on the value of a variable:
+
+.. code-block:: jinja
+
+    {% include var ~ '_foo.html' %}
+
+If ``var`` evaluates to ``index``, the ``index_foo.html`` template will be
+rendered.
+
+As a matter of fact, the template name can be any valid expression, such as
+the following:
+
+.. code-block:: jinja
+
+    {% include var|default('index') ~ '_foo.html' %}
+
+Overriding a Template that also extends itself
+----------------------------------------------
+
+A template can be customized in two different ways:
+
+* *Inheritance*: A template *extends* a parent template and overrides some
+  blocks;
+
+* *Replacement*: If you use the filesystem loader, Twig loads the first
+  template it finds in a list of configured directories; a template found in a
+  directory *replaces* another one from a directory further in the list.
+
+But how do you combine both: *replace* a template that also extends itself
+(aka a template in a directory further in the list)?
+
+Let's say that your templates are loaded from both ``.../templates/mysite``
+and ``.../templates/default`` in this order. The ``page.twig`` template,
+stored in ``.../templates/default`` reads as follows:
+
+.. code-block:: jinja
+
+    {# page.twig #}
+    {% extends "layout.twig" %}
+
+    {% block content %}
+    {% endblock %}
+
+You can replace this template by putting a file with the same name in
+``.../templates/mysite``. And if you want to extend the original template, you
+might be tempted to write the following:
+
+.. code-block:: jinja
+
+    {# page.twig in .../templates/mysite #}
+    {% extends "page.twig" %} {# from .../templates/default #}
+
+Of course, this will not work as Twig will always load the template from
+``.../templates/mysite``.
+
+It turns out it is possible to get this to work, by adding a directory right
+at the end of your template directories, which is the parent of all of the
+other directories: ``.../templates`` in our case. This has the effect of
+making every template file within our system uniquely addressable. Most of the
+time you will use the "normal" paths, but in the special case of wanting to
+extend a template with an overriding version of itself we can reference its
+parent's full, unambiguous template path in the extends tag:
+
+.. code-block:: jinja
+
+    {# page.twig in .../templates/mysite #}
+    {% extends "default/page.twig" %} {# from .../templates #}
+
+.. note::
+
+    This recipe was inspired by the following Django wiki page:
+    http://code.djangoproject.com/wiki/ExtendingTemplates
+
+Customizing the Syntax
+----------------------
+
+Twig allows some syntax customization for the block delimiters. It's not
+recommended to use this feature as templates will be tied with your custom
+syntax. But for specific projects, it can make sense to change the defaults.
+
+To change the block delimiters, you need to create your own lexer object::
+
+    $twig = new Twig_Environment();
+
+    $lexer = new Twig_Lexer($twig, array(
+        'tag_comment'   => array('{#', '#}'),
+        'tag_block'     => array('{%', '%}'),
+        'tag_variable'  => array('{{', '}}'),
+        'interpolation' => array('#{', '}'),
+    ));
+    $twig->setLexer($lexer);
+
+Here are some configuration example that simulates some other template engines
+syntax::
+
+    // Ruby erb syntax
+    $lexer = new Twig_Lexer($twig, array(
+        'tag_comment'  => array('<%#', '%>'),
+        'tag_block'    => array('<%', '%>'),
+        'tag_variable' => array('<%=', '%>'),
+    ));
+
+    // SGML Comment Syntax
+    $lexer = new Twig_Lexer($twig, array(
+        'tag_comment'  => array('<!--#', '-->'),
+        'tag_block'    => array('<!--', '-->'),
+        'tag_variable' => array('${', '}'),
+    ));
+
+    // Smarty like
+    $lexer = new Twig_Lexer($twig, array(
+        'tag_comment'  => array('{*', '*}'),
+        'tag_block'    => array('{', '}'),
+        'tag_variable' => array('{$', '}'),
+    ));
+
+Using dynamic Object Properties
+-------------------------------
+
+When Twig encounters a variable like ``article.title``, it tries to find a
+``title`` public property in the ``article`` object.
+
+It also works if the property does not exist but is rather defined dynamically
+thanks to the magic ``__get()`` method; you just need to also implement the
+``__isset()`` magic method like shown in the following snippet of code::
+
+    class Article
+    {
+        public function __get($name)
+        {
+            if ('title' == $name) {
+                return 'The title';
+            }
+
+            // throw some kind of error
+        }
+
+        public function __isset($name)
+        {
+            if ('title' == $name) {
+                return true;
+            }
+
+            return false;
+        }
+    }
+
+Accessing the parent Context in Nested Loops
+--------------------------------------------
+
+Sometimes, when using nested loops, you need to access the parent context. The
+parent context is always accessible via the ``loop.parent`` variable. For
+instance, if you have the following template data::
+
+    $data = array(
+        'topics' => array(
+            'topic1' => array('Message 1 of topic 1', 'Message 2 of topic 1'),
+            'topic2' => array('Message 1 of topic 2', 'Message 2 of topic 2'),
+        ),
+    );
+
+And the following template to display all messages in all topics:
+
+.. code-block:: jinja
+
+    {% for topic, messages in topics %}
+        * {{ loop.index }}: {{ topic }}
+      {% for message in messages %}
+          - {{ loop.parent.loop.index }}.{{ loop.index }}: {{ message }}
+      {% endfor %}
+    {% endfor %}
+
+The output will be similar to:
+
+.. code-block:: text
+
+    * 1: topic1
+      - 1.1: The message 1 of topic 1
+      - 1.2: The message 2 of topic 1
+    * 2: topic2
+      - 2.1: The message 1 of topic 2
+      - 2.2: The message 2 of topic 2
+
+In the inner loop, the ``loop.parent`` variable is used to access the outer
+context. So, the index of the current ``topic`` defined in the outer for loop
+is accessible via the ``loop.parent.loop.index`` variable.
+
+Defining undefined Functions and Filters on the Fly
+---------------------------------------------------
+
+When a function (or a filter) is not defined, Twig defaults to throw a
+``Twig_Error_Syntax`` exception. However, it can also call a `callback`_ (any
+valid PHP callable) which should return a function (or a filter).
+
+For filters, register callbacks with ``registerUndefinedFilterCallback()``.
+For functions, use ``registerUndefinedFunctionCallback()``::
+
+    // auto-register all native PHP functions as Twig functions
+    // don't try this at home as it's not secure at all!
+    $twig->registerUndefinedFunctionCallback(function ($name) {
+        if (function_exists($name)) {
+            return new Twig_Function_Function($name);
+        }
+
+        return false;
+    });
+
+If the callable is not able to return a valid function (or filter), it must
+return ``false``.
+
+If you register more than one callback, Twig will call them in turn until one
+does not return ``false``.
+
+.. tip::
+
+    As the resolution of functions and filters is done during compilation,
+    there is no overhead when registering these callbacks.
+
+Validating the Template Syntax
+------------------------------
+
+When template code is providing by a third-party (through a web interface for
+instance), it might be interesting to validate the template syntax before
+saving it. If the template code is stored in a `$template` variable, here is
+how you can do it::
+
+    try {
+        $twig->parse($twig->tokenize($template));
+
+        // the $template is valid
+    } catch (Twig_Error_Syntax $e) {
+        // $template contains one or more syntax errors
+    }
+
+If you iterate over a set of files, you can pass the filename to the
+``tokenize()`` method to get the filename in the exception message::
+
+    foreach ($files as $file) {
+        try {
+            $twig->parse($twig->tokenize($template, $file));
+
+            // the $template is valid
+        } catch (Twig_Error_Syntax $e) {
+            // $template contains one or more syntax errors
+        }
+    }
+
+.. note::
+
+    This method won't catch any sandbox policy violations because the policy
+    is enforced during template rendering (as Twig needs the context for some
+    checks like allowed methods on objects).
+
+Refreshing modified Templates when APC is enabled and apc.stat = 0
+------------------------------------------------------------------
+
+When using APC with ``apc.stat`` set to ``0`` and Twig cache enabled, clearing
+the template cache won't update the APC cache. To get around this, one can
+extend ``Twig_Environment`` and force the update of the APC cache when Twig
+rewrites the cache::
+
+    class Twig_Environment_APC extends Twig_Environment
+    {
+        protected function writeCacheFile($file, $content)
+        {
+            parent::writeCacheFile($file, $content);
+
+            // Compile cached file into bytecode cache
+            apc_compile_file($file);
+        }
+    }
+
+Reusing a stateful Node Visitor
+-------------------------------
+
+When attaching a visitor to a ``Twig_Environment`` instance, Twig uses it to
+visit *all* templates it compiles. If you need to keep some state information
+around, you probably want to reset it when visiting a new template.
+
+This can be easily achieved with the following code::
+
+    protected $someTemplateState = array();
+
+    public function enterNode(Twig_NodeInterface $node, Twig_Environment $env)
+    {
+        if ($node instanceof Twig_Node_Module) {
+            // reset the state as we are entering a new template
+            $this->someTemplateState = array();
+        }
+
+        // ...
+
+        return $node;
+    }
+
+Using the Template name to set the default Escaping Strategy
+------------------------------------------------------------
+
+.. versionadded:: 1.8
+    This recipe requires Twig 1.8 or later.
+
+The ``autoescape`` option determines the default escaping strategy to use when
+no escaping is applied on a variable. When Twig is used to mostly generate
+HTML files, you can set it to ``html`` and explicitly change it to ``js`` when
+you have some dynamic JavaScript files thanks to the ``autoescape`` tag:
+
+.. code-block:: jinja
+
+    {% autoescape 'js' %}
+        ... some JS ...
+    {% endautoescape %}
+
+But if you have many HTML and JS files, and if your template names follow some
+conventions, you can instead determine the default escaping strategy to use
+based on the template name. Let's say that your template names always ends
+with ``.html`` for HTML files, ``.js`` for JavaScript ones, and ``.css`` for
+stylesheets, here is how you can configure Twig::
+
+    class TwigEscapingGuesser
+    {
+        function guess($filename)
+        {
+            // get the format
+            $format = substr($filename, strrpos($filename, '.') + 1);
+
+            switch ($format) {
+                case 'js':
+                    return 'js';
+                case 'css':
+                    return 'css';
+                case 'html':
+                default:
+                    return 'html';
+            }
+        }
+    }
+
+    $loader = new Twig_Loader_Filesystem('/path/to/templates');
+    $twig = new Twig_Environment($loader, array(
+        'autoescape' => array(new TwigEscapingGuesser(), 'guess'),
+    ));
+
+This dynamic strategy does not incur any overhead at runtime as auto-escaping
+is done at compilation time.
+
+Using a Database to store Templates
+-----------------------------------
+
+If you are developing a CMS, templates are usually stored in a database. This
+recipe gives you a simple PDO template loader you can use as a starting point
+for your own.
+
+First, let's create a temporary in-memory SQLite3 database to work with::
+
+    $dbh = new PDO('sqlite::memory:');
+    $dbh->exec('CREATE TABLE templates (name STRING, source STRING, last_modified INTEGER)');
+    $base = '{% block content %}{% endblock %}';
+    $index = '
+    {% extends "base.twig" %}
+    {% block content %}Hello {{ name }}{% endblock %}
+    ';
+    $now = time();
+    $dbh->exec("INSERT INTO templates (name, source, last_modified) VALUES ('base.twig', '$base', $now)");
+    $dbh->exec("INSERT INTO templates (name, source, last_modified) VALUES ('index.twig', '$index', $now)");
+
+We have created a simple ``templates`` table that hosts two templates:
+``base.twig`` and ``index.twig``.
+
+Now, let's define a loader able to use this database::
+
+    class DatabaseTwigLoader implements Twig_LoaderInterface, Twig_ExistsLoaderInterface
+    {
+        protected $dbh;
+
+        public function __construct(PDO $dbh)
+        {
+            $this->dbh = $dbh;
+        }
+
+        public function getSource($name)
+        {
+            if (false === $source = $this->getValue('source', $name)) {
+                throw new Twig_Error_Loader(sprintf('Template "%s" does not exist.', $name));
+            }
+
+            return $source;
+        }
+
+        // Twig_ExistsLoaderInterface as of Twig 1.11
+        public function exists($name)
+        {
+            return $name === $this->getValue('name', $name);
+        }
+
+        public function getCacheKey($name)
+        {
+            return $name;
+        }
+
+        public function isFresh($name, $time)
+        {
+            if (false === $lastModified = $this->getValue('last_modified', $name)) {
+                return false;
+            }
+
+            return $lastModified <= $time;
+        }
+
+        protected function getValue($column, $name)
+        {
+            $sth = $this->dbh->prepare('SELECT '.$column.' FROM templates WHERE name = :name');
+            $sth->execute(array(':name' => (string) $name));
+
+            return $sth->fetchColumn();
+        }
+    }
+
+Finally, here is an example on how you can use it::
+
+    $loader = new DatabaseTwigLoader($dbh);
+    $twig = new Twig_Environment($loader);
+
+    echo $twig->render('index.twig', array('name' => 'Fabien'));
+
+Using different Template Sources
+--------------------------------
+
+This recipe is the continuation of the previous one. Even if you store the
+contributed templates in a database, you might want to keep the original/base
+templates on the filesystem. When templates can be loaded from different
+sources, you need to use the ``Twig_Loader_Chain`` loader.
+
+As you can see in the previous recipe, we reference the template in the exact
+same way as we would have done it with a regular filesystem loader. This is
+the key to be able to mix and match templates coming from the database, the
+filesystem, or any other loader for that matter: the template name should be a
+logical name, and not the path from the filesystem::
+
+    $loader1 = new DatabaseTwigLoader($dbh);
+    $loader2 = new Twig_Loader_Array(array(
+        'base.twig' => '{% block content %}{% endblock %}',
+    ));
+    $loader = new Twig_Loader_Chain(array($loader1, $loader2));
+
+    $twig = new Twig_Environment($loader);
+
+    echo $twig->render('index.twig', array('name' => 'Fabien'));
+
+Now that the ``base.twig`` templates is defined in an array loader, you can
+remove it from the database, and everything else will still work as before.

+``autoescape``
+==============
+
+Whether automatic escaping is enabled or not, you can mark a section of a
+template to be escaped or not by using the ``autoescape`` tag:
+
+.. code-block:: jinja
+
+    {# The following syntax works as of Twig 1.8 -- see the note below for previous versions #}
+
+    {% autoescape %}
+        Everything will be automatically escaped in this block
+        using the HTML strategy
+    {% endautoescape %}

+
+    {% autoescape 'js' %}
+        Everything will be automatically escaped in this block
+        using the js escaping strategy
+    {% endautoescape %}
+
+    {% autoescape false %}
+        Everything will be outputted as is in this block
+    {% endautoescape %}
+
+.. note::
+
+    Before Twig 1.8, the syntax was different:
+
+    .. code-block:: jinja
+
+        {% autoescape true %}
+            Everything will be automatically escaped in this block
+            using the HTML strategy
+        {% endautoescape %}
+
+        {% autoescape false %}

+            Everything will be automatically escaped in this block
+            using the js escaping strategy
+        {% endautoescape %}
+
+When automatic escaping is enabled everything is escaped by default except for
+values explicitly marked as safe. Those can be marked in the template by using
+the :doc:`raw<../filters/raw>` filter:
+
+.. code-block:: jinja
+
+    {% autoescape %}
+        {{ safe_value|raw }}
+    {% endautoescape %}
+
+Functions returning template data (like :doc:`macros<macro>` and
+:doc:`parent<../functions/parent>`) always return safe markup.
+
+.. note::
+
+    Twig is smart enough to not escape an already escaped value by the
+    :doc:`escape<../filters/escape>` filter.
+
+.. note::
+
+    The chapter :doc:`Twig for Developers<../api>` gives more information
+    about when and how automatic escaping is applied.

+Think of an embedded template as a "micro layout skeleton".
+
+.. code-block:: jinja
+
+    {% embed "teasers_skeleton.twig" %}
+        {# These blocks are defined in "teasers_skeleton.twig" #}
+        {# and we override them right here:                    #}
+        {% block left_teaser %}
+            Some content for the left teaser box
+        {% endblock %}
+        {% block right_teaser %}
+            Some content for the right teaser box
+        {% endblock %}
+    {% endembed %}
+
+The ``embed`` tag takes the idea of template inheritance to the level of
+content fragments. While template inheritance allows for "document skeletons",
+which are filled with life by child templates, the ``embed`` tag allows you to
+create "skeletons" for smaller units of content and re-use and fill them
+anywhere you like.
+
+Since the use case may not be obvious, let's look at a simplified example.
+Imagine a base template shared by multiple HTML pages, defining a single block
+named "content":
+
+.. code-block:: text
+
+    ┌─── page layout ─────────────────────┐
+    │                                     │
+    │           ┌── block "content" ──┐   │
+    │           │                     │   │
+    │           │                     │   │
+    │           │ (child template to  │   │
+    │           │  put content here)  │   │
+    │           │                     │   │
+    │           │                     │   │
+    │           └─────────────────────┘   │
+    │                                     │
+    └─────────────────────────────────────┘
+
+Some pages ("foo" and "bar") share the same content structure -
+two vertically stacked boxes:
+
+.. code-block:: text
+
+    ┌─── page layout ─────────────────────┐
+    │                                     │
+    │           ┌── block "content" ──┐   │
+    │           │ ┌─ block "top" ───┐ │   │
+    │           │ │                 │ │   │
+    │           │ └─────────────────┘ │   │
+    │           │ ┌─ block "bottom" ┐ │   │
+    │           │ │                 │ │   │
+    │           │ └─────────────────┘ │   │
+    │           └─────────────────────┘   │
+    │                                     │
+    └─────────────────────────────────────┘
+
+While other pages ("boom" and "baz") share a different content structure -
+two boxes side by side:
+
+.. code-block:: text
+
+    ┌─── page layout ─────────────────────┐
+    │                                     │
+    │           ┌── block "content" ──┐   │
+    │           │                     │   │    
+    │           │ ┌ block ┐ ┌ block ┐ │   │
+    │           │ │"left" │ │"right"│ │   │
+    │           │ │       │ │       │ │   │
+    │           │ │       │ │       │ │   │
+    │           │ └───────┘ └───────┘ │   │
+    │           └─────────────────────┘   │
+    │                                     │
+    └─────────────────────────────────────┘
+
+Without the ``embed`` tag, you have two ways to design your templates:
+
+ * Create two "intermediate" base templates that extend the master layout
+   template: one with vertically stacked boxes to be used by the "foo" and
+   "bar" pages and another one with side-by-side boxes for the "boom" and
+   "baz" pages.
+
+ * Embed the markup for the top/bottom and left/right boxes into each page 
+   template directly.
+
+These two solutions do not scale well because they each have a major drawback:
+
+ * The first solution may indeed work for this simplified example. But imagine
+   we add a sidebar, which may again contain different, recurring structures
+   of content. Now we would need to create intermediate base templates for
+   all occurring combinations of content structure and sidebar structure...
+   and so on.
+
+ * The second solution involves duplication of common code with all its negative
+   consequences: any change involves finding and editing all affected copies
+   of the structure, correctness has to be verified for each copy, copies may
+   go out of sync by careless modifications etc.
+
+In such a situation, the ``embed`` tag comes in handy. The common layout
+code can live in a single base template, and the two different content structures,
+let's call them "micro layouts" go into separate templates which are embedded
+as necessary:
+
+Page template ``foo.twig``:
+
+.. code-block:: jinja
+
+    {% extends "layout_skeleton.twig" %}
+
+    {% block content %}
+        {% embed "vertical_boxes_skeleton.twig" %}
+            {% block top %}
+                Some content for the top box
+            {% endblock %}
+
+            {% block bottom %}
+                Some content for the bottom box
+            {% endblock %}
+        {% endembed %}
+    {% endblock %}
+
+And here is the code for ``vertical_boxes_skeleton.twig``:
+
+.. code-block:: html+jinja
+
+    <div class="top_box">
+        {% block top %}
+            Top box default content
+        {% endblock %}
+    </div>
+
+    <div class="bottom_box">
+        {% block bottom %}
+            Bottom box default content
+        {% endblock %}
+    </div>
+
+The goal of the ``vertical_boxes_skeleton.twig`` template being to factor
+out the HTML markup for the boxes.
+
+The ``embed`` tag takes the exact same arguments as the ``include`` tag:
+
+.. code-block:: jinja
+
+    {% embed "base" with {'foo': 'bar'} %}
+        ...
+    {% endembed %}
+
+    {% embed "base" with {'foo': 'bar'} only %}
+        ...
+    {% endembed %}
+
+    {% embed "base" ignore missing %}
+        ...
+    {% endembed %}
+
+.. warning::
+
+    As embedded templates do not have "names", auto-escaping strategies based
+    on the template "filename" won't work as expected if you change the
+    context (for instance, if you embed a CSS/JavaScript template into an HTML
+    one). In that case, explicitly set the default auto-escaping strategy with
+    the ``autoescape`` tag.

+``extends``
+===========
+
+The ``extends`` tag can be used to extend a template from another one.
+
+.. note::
+
+    Like PHP, Twig does not support multiple inheritance. So you can only have
+    one extends tag called per rendering. However, Twig supports horizontal
+    :doc:`reuse<use>`.
+
+Let's define a base template, ``base.html``, which defines a simple HTML
+skeleton document:
+
+.. code-block:: html+jinja
+
+    <!DOCTYPE html>
+    <html>
+        <head>
+            {% block head %}
+                <link rel="stylesheet" href="style.css" />
+                <title>{% block title %}{% endblock %} - My Webpage</title>
+            {% endblock %}
+        </head>
+        <body>
+            <div id="content">{% block content %}{% endblock %}</div>
+            <div id="footer">
+                {% block footer %}
+                    &copy; Copyright 2011 by <a href="http://domain.invalid/">you</a>.
+                {% endblock %}
+            </div>
+        </body>
+    </html>
+
+In this example, the :doc:`block<block>` tags define four blocks that child
+templates can fill in.
+
+All the ``block`` tag does is to tell the template engine that a child
+template may override those portions of the template.
+
+Child Template
+--------------
+
+A child template might look like this:
+
+.. code-block:: jinja
+
+    {% extends "base.html" %}
+
+    {% block title %}Index{% endblock %}
+    {% block head %}
+        {{ parent() }}
+        <style type="text/css">
+            .important { color: #336699; }
+        </style>
+    {% endblock %}
+    {% block content %}
+        <h1>Index</h1>
+        <p class="important">
+            Welcome on my awesome homepage.
+        </p>
+    {% endblock %}
+
+The ``extends`` tag is the key here. It tells the template engine that this
+template "extends" another template. When the template system evaluates this
+template, first it locates the parent. The extends tag should be the first tag
+in the template.
+
+Note that since the child template doesn't define the ``footer`` block, the
+value from the parent template is used instead.
+
+You can't define multiple ``block`` tags with the same name in the same
+template. This limitation exists because a block tag works in "both"
+directions. That is, a block tag doesn't just provide a hole to fill - it also
+defines the content that fills the hole in the *parent*. If there were two
+similarly-named ``block`` tags in a template, that template's parent wouldn't
+know which one of the blocks' content to use.
+
+If you want to print a block multiple times you can however use the
+``block`` function:
+
+.. code-block:: jinja
+
+    <title>{% block title %}{% endblock %}</title>
+    <h1>{{ block('title') }}</h1>
+    {% block body %}{% endblock %}
+
+Parent Blocks
+-------------
+
+It's possible to render the contents of the parent block by using the
+:doc:`parent<../functions/parent>` function. This gives back the results of
+the parent block:
+
+.. code-block:: jinja
+
+    {% block sidebar %}
+        <h3>Table Of Contents</h3>
+        ...
+        {{ parent() }}
+    {% endblock %}
+
+Named Block End-Tags
+--------------------
+
+Twig allows you to put the name of the block after the end tag for better
+readability:
+
+.. code-block:: jinja
+
+    {% block sidebar %}
+        {% block inner_sidebar %}
+            ...
+        {% endblock inner_sidebar %}
+    {% endblock sidebar %}
+
+Of course, the name after the ``endblock`` word must match the block name.
+
+Block Nesting and Scope
+-----------------------
+
+Blocks can be nested for more complex layouts. Per default, blocks have access
+to variables from outer scopes:
+
+.. code-block:: jinja
+
+    {% for item in seq %}
+        <li>{% block loop_item %}{{ item }}{% endblock %}</li>
+    {% endfor %}
+
+Block Shortcuts
+---------------
+
+For blocks with few content, it's possible to use a shortcut syntax. The
+following constructs do the same:
+
+.. code-block:: jinja
+
+    {% block title %}
+        {{ page_title|title }}
+    {% endblock %}
+
+.. code-block:: jinja
+
+    {% block title page_title|title %}
+
+Dynamic Inheritance
+-------------------
+
+Twig supports dynamic inheritance by using a variable as the base template:
+
+.. code-block:: jinja
+
+    {% extends some_var %}
+
+If the variable evaluates to a ``Twig_Template`` object, Twig will use it as
+the parent template::
+
+    // {% extends layout %}
+
+    $layout = $twig->loadTemplate('some_layout_template.twig');
+
+    $twig->display('template.twig', array('layout' => $layout));
+
+.. versionadded:: 1.2
+    The possibility to pass an array of templates has been added in Twig 1.2.
+
+You can also provide a list of templates that are checked for existence. The
+first template that exists will be used as a parent:
+
+.. code-block:: jinja
+
+    {% extends ['layout.html', 'base_layout.html'] %}
+
+Conditional Inheritance
+-----------------------
+
+As the template name for the parent can be any valid Twig expression, it's
+possible to make the inheritance mechanism conditional:
+
+.. code-block:: jinja
+
+    {% extends standalone ? "minimum.html" : "base.html" %}
+
+In this example, the template will extend the "minimum.html" layout template
+if the ``standalone`` variable evaluates to ``true``, and "base.html"
+otherwise.
+
+How blocks work?
+----------------
+
+A block provides a way to change how a certain part of a template is rendered
+but it does not interfere in any way with the logic around it.
+
+Let's take the following example to illustrate how a block work and more
+importantly, how it does not work:
+
+.. code-block:: jinja
+
+    {# base.twig #}
+
+    {% for post in posts %}
+        {% block post %}
+            <h1>{{ post.title }}</h1>
+            <p>{{ post.body }}</p>
+        {% endblock %}
+    {% endfor %}
+
+If you render this template, the result would be exactly the same with or
+without the ``block`` tag. The ``block`` inside the ``for`` loop is just a way
+to make it overridable by a child template:
+
+.. code-block:: jinja
+
+    {# child.twig #}
+
+    {% extends "base.twig" %}
+
+    {% block post %}
+        <article>
+            <header>{{ post.title }}</header>
+            <section>{{ post.text }}</section>
+        </article>
+    {% endblock %}
+
+Now, when rendering the child template, the loop is going to use the block
+defined in the child template instead of the one defined in the base one; the
+executed template is then equivalent to the following one:
+
+.. code-block:: jinja
+
+    {% for post in posts %}
+        <article>
+            <header>{{ post.title }}</header>
+            <section>{{ post.text }}</section>
+        </article>
+    {% endfor %}
+
+Let's take another example: a block included within an ``if`` statement:
+
+.. code-block:: jinja
+
+    {% if posts is empty %}
+        {% block head %}
+            {{ parent() }}
+
+            <meta name="robots" content="noindex, follow">
+        {% endblock head %}
+    {% endif %}
+
+Contrary to what you might think, this template does not define a block
+conditionally; it just makes overridable by a child template the output of
+what will be rendered when the condition is ``true``.
+
+If you want the output to be displayed conditionally, use the following
+instead:
+
+.. code-block:: jinja
+
+    {% block head %}
+        {{ parent() }}
+
+        {% if posts is empty %}
+            <meta name="robots" content="noindex, follow">
+        {% endif %}
+    {% endblock head %}
+
+.. seealso:: :doc:`block<../functions/block>`, :doc:`block<../tags/block>`, :doc:`parent<../functions/parent>`, :doc:`use<../tags/use>`

+
+Loop over each item in a sequence. For example, to display a list of users

+
+    <h1>Members</h1>
+    <ul>
+        {% for user in users %}

+    </ul>
+
+.. note::
+
+    A sequence can be either an array or an object implementing the
+    ``Traversable`` interface.
+
+If you do need to iterate over a sequence of numbers, you can use the ``..``
+operator:
+
+.. code-block:: jinja
+
+    {% for i in 0..10 %}
+        * {{ i }}
+    {% endfor %}
+
+The above snippet of code would print all numbers from 0 to 10.

+
+.. code-block:: jinja
+
+    {% for letter in 'a'..'z' %}
+        * {{ letter }}
+    {% endfor %}
+
+The ``..`` operator can take any expression at both sides:
+
+.. code-block:: jinja
+
+    {% for letter in 'a'|upper..'z'|upper %}
+        * {{ letter }}
+    {% endfor %}
+
+.. tip:
+
+    If you need a step different from 1, you can use the ``range`` function
+    instead.
+
+The `loop` variable
+-------------------
+
+Inside of a ``for`` loop block you can access some special variables:
+
+===================== =============================================================
+Variable              Description
+===================== =============================================================
+``loop.index``        The current iteration of the loop. (1 indexed)
+``loop.index0``       The current iteration of the loop. (0 indexed)
+``loop.revindex``     The number of iterations from the end of the loop (1 indexed)
+``loop.revindex0``    The number of iterations from the end of the loop (0 indexed)
+``loop.first``        True if first iteration
+``loop.last``         True if last iteration
+``loop.length``       The number of items in the sequence
+``loop.parent``       The parent context
+===================== =============================================================
+
+.. code-block:: jinja
+
+    {% for user in users %}
+        {{ loop.index }} - {{ user.username }}
+    {% endfor %}
+
+.. note::
+
+    The ``loop.length``, ``loop.revindex``, ``loop.revindex0``, and
+    ``loop.last`` variables are only available for PHP arrays, or objects that
+    implement the ``Countable`` interface. They are also not available when
+    looping with a condition.
+
+.. versionadded:: 1.2
+    The ``if`` modifier support has been added in Twig 1.2.
+
+Adding a condition
+------------------
+
+Unlike in PHP, it's not possible to ``break`` or ``continue`` in a loop. You
+can however filter the sequence during iteration which allows you to skip
+items. The following example skips all the users which are not active:
+
+.. code-block:: jinja
+
+    <ul>
+        {% for user in users if user.active %}
+            <li>{{ user.username|e }}</li>
+        {% endfor %}
+    </ul>
+
+The advantage is that the special loop variable will count correctly thus not
+counting the users not iterated over. Keep in mind that properties like
+``loop.last`` will not be defined when using loop conditions.
+
+.. note::
+
+    Using the ``loop`` variable within the condition is not recommended as it
+    will probably not be doing what you expect it to. For instance, adding a
+    condition like ``loop.index > 4`` won't work as the index is only
+    incremented when the condition is true (so the condition will never
+    match).
+
+The `else` Clause
+-----------------
+
+If no iteration took place because the sequence was empty, you can render a
+replacement block by using ``else``:
+
+.. code-block:: jinja
+
+    <ul>
+        {% for user in users %}
+            <li>{{ user.username|e }}</li>
+        {% else %}
+            <li><em>no user found</em></li>
+        {% endfor %}
+    </ul>
+
+Iterating over Keys
+-------------------
+
+By default, a loop iterates over the values of the sequence. You can iterate
+on keys by using the ``keys`` filter:
+
+.. code-block:: jinja
+
+    <h1>Members</h1>
+    <ul>
+        {% for key in users|keys %}
+            <li>{{ key }}</li>
+        {% endfor %}
+    </ul>
+
+Iterating over Keys and Values
+------------------------------
+
+You can also access both keys and values:
+
+.. code-block:: jinja
+
+    <h1>Members</h1>
+    <ul>
+        {% for key, user in users %}

+Iterating over a Subset
+-----------------------
+
+You might want to iterate over a subset of values. This can be achieved using
+the :doc:`slice <../filters/slice>` filter:
+
+.. code-block:: jinja
+
+    <h1>Top Ten Members</h1>
+    <ul>
+        {% for user in users|slice(0, 10) %}
+            <li>{{ user.username|e }}</li>
+        {% endfor %}
+    </ul>

+``import``
+==========
+
+Twig supports putting often used code into :doc:`macros<../tags/macro>`. These
+macros can go into different templates and get imported from there.
+
+There are two ways to import templates. You can import the complete template
+into a variable or request specific macros from it.
+
+Imagine we have a helper module that renders forms (called ``forms.html``):
+
+.. code-block:: jinja
+
+    {% macro input(name, value, type, size) %}
+        <input type="{{ type|default('text') }}" name="{{ name }}" value="{{ value|e }}" size="{{ size|default(20) }}" />
+    {% endmacro %}
+
+    {% macro textarea(name, value, rows) %}
+        <textarea name="{{ name }}" rows="{{ rows|default(10) }}" cols="{{ cols|default(40) }}">{{ value|e }}</textarea>
+    {% endmacro %}
+
+The easiest and most flexible is importing the whole module into a variable.
+That way you can access the attributes:
+
+.. code-block:: jinja
+
+    {% import 'forms.html' as forms %}
+
+    <dl>
+        <dt>Username</dt>
+        <dd>{{ forms.input('username') }}</dd>
+        <dt>Password</dt>
+        <dd>{{ forms.input('password', null, 'password') }}</dd>
+    </dl>
+    <p>{{ forms.textarea('comment') }}</p>
+
+Alternatively you can import names from the template into the current
+namespace:
+
+.. code-block:: jinja
+
+    {% from 'forms.html' import input as input_field, textarea %}
+
+    <dl>
+        <dt>Username</dt>
+        <dd>{{ input_field('username') }}</dd>
+        <dt>Password</dt>
+        <dd>{{ input_field('password', '', 'password') }}</dd>
+    </dl>
+    <p>{{ textarea('comment') }}</p>
+
+.. tip::
+
+    To import macros from the current file, use the special ``_self`` variable
+    for the source.
+
+.. seealso:: :doc:`macro<../tags/macro>`, :doc:`from<../tags/from>`

+``include``
+===========
+
+The ``include`` statement includes a template and return the rendered content
+of that file into the current namespace:
+
+.. code-block:: jinja
+
+    {% include 'header.html' %}
+        Body
+    {% include 'footer.html' %}
+
+Included templates have access to the variables of the active context.
+
+If you are using the filesystem loader, the templates are looked for in the
+paths defined by it.
+
+You can add additional variables by passing them after the ``with`` keyword:
+
+.. code-block:: jinja
+
+    {# template.html will have access to the variables from the current context and the additional ones provided #}
+    {% include 'template.html' with {'foo': 'bar'} %}
+
+    {% set vars = {'foo': 'bar'} %}
+    {% include 'template.html' with vars %}
+
+You can disable access to the context by appending the ``only`` keyword:
+
+.. code-block:: jinja
+
+    {# only the foo variable will be accessible #}
+    {% include 'template.html' with {'foo': 'bar'} only %}
+
+.. code-block:: jinja
+
+    {# no variables will be accessible #}
+    {% include 'template.html' only %}
+
+.. tip::
+
+    When including a template created by an end user, you should consider
+    sandboxing it. More information in the :doc:`Twig for Developers<../api>`
+    chapter and in the :doc:`sandbox<../tags/sandbox>` tag documentation.
+
+The template name can be any valid Twig expression:
+
+.. code-block:: jinja
+
+    {% include some_var %}
+    {% include ajax ? 'ajax.html' : 'not_ajax.html' %}
+
+And if the expression evaluates to a ``Twig_Template`` object, Twig will use it
+directly::
+
+    // {% include template %}
+
+    $template = $twig->loadTemplate('some_template.twig');
+
+    $twig->loadTemplate('template.twig')->display(array('template' => $template));
+
+.. versionadded:: 1.2
+    The ``ignore missing`` feature has been added in Twig 1.2.
+
+You can mark an include with ``ignore missing`` in which case Twig will ignore
+the statement if the template to be included does not exist. It has to be
+placed just after the template name. Here some valid examples:
+
+.. code-block:: jinja
+
+    {% include 'sidebar.html' ignore missing %}
+    {% include 'sidebar.html' ignore missing with {'foo': 'bar'} %}
+    {% include 'sidebar.html' ignore missing only %}
+
+.. versionadded:: 1.2
+    The possibility to pass an array of templates has been added in Twig 1.2.
+
+You can also provide a list of templates that are checked for existence before
+inclusion. The first template that exists will be included:
+
+.. code-block:: jinja
+
+    {% include ['page_detailed.html', 'page.html'] %}
+
+If ``ignore missing`` is given, it will fall back to rendering nothing if none
+of the templates exist, otherwise it will throw an exception.

+``macro``
+=========
+
+Macros are comparable with functions in regular programming languages. They
+are useful to put often used HTML idioms into reusable elements to not repeat
+yourself.
+
+Here is a small example of a macro that renders a form element:
+
+.. code-block:: jinja
+
+    {% macro input(name, value, type, size) %}
+        <input type="{{ type|default('text') }}" name="{{ name }}" value="{{ value|e }}" size="{{ size|default(20) }}" />
+    {% endmacro %}
+
+Macros differs from native PHP functions in a few ways:
+
+* Default argument values are defined by using the ``default`` filter in the
+  macro body;
+
+* Arguments of a macro are always optional.
+
+But as with PHP functions, macros don't have access to the current template
+variables.
+
+.. tip::
+
+    You can pass the whole context as an argument by using the special
+    ``_context`` variable.
+
+Macros can be defined in any template, and need to be "imported" before being
+used (see the documentation for the :doc:`import<../tags/import>` tag for more
+information):
+
+.. code-block:: jinja
+
+    {% import "forms.html" as forms %}
+
+The above ``import`` call imports the "forms.html" file (which can contain only
+macros, or a template and some macros), and import the functions as items of
+the ``forms`` variable.
+
+The macro can then be called at will:
+
+.. code-block:: jinja
+
+    <p>{{ forms.input('username') }}</p>
+    <p>{{ forms.input('password', null, 'password') }}</p>
+
+If macros are defined and used in the same template, you can use the
+special ``_self`` variable to import them:
+
+.. code-block:: jinja
+
+    {% import _self as forms %}
+
+    <p>{{ forms.input('username') }}</p>
+
+.. warning::
+
+    When you define a macro in the template where you are going to use it, you
+    might be tempted to call the macro directly via ``_self.input()`` instead
+    of importing it; even if seems to work, this is just a side-effect of the
+    current implementation and it won't work anymore in Twig 2.x.
+
+When you want to use a macro in another macro from the same file, you need to
+import it locally:
+
+.. code-block:: jinja
+
+    {% macro input(name, value, type, size) %}
+        <input type="{{ type|default('text') }}" name="{{ name }}" value="{{ value|e }}" size="{{ size|default(20) }}" />
+    {% endmacro %}
+
+    {% macro wrapped_input(name, value, type, size) %}
+        {% import _self as forms %}
+
+        <div class="field">
+            {{ forms.input(name, value, type, size) }}
+        </div>
+    {% endmacro %}
+

+``sandbox``
+===========
+
+The ``sandbox`` tag can be used to enable the sandboxing mode for an included

+``set``
+=======
+
+Inside code blocks you can also assign values to variables. Assignments use
+the ``set`` tag and can have multiple targets.
+
+Here is how you can assign the ``bar`` value to the ``foo`` variable:
+
+.. code-block:: jinja
+
+    {% set foo = 'bar' %}
+
+After the ``set`` call, the ``foo`` variable is available in the template like
+any other ones:
+
+.. code-block:: jinja
+
+    {# displays bar #}
+    {{ foo }}
+
+The assigned value can be any valid :ref:`Twig expressions
+<twig-expressions>`:
+
+.. code-block:: jinja
+
+    {% set foo = [1, 2] %}
+    {% set foo = {'foo': 'bar'} %}
+    {% set foo = 'foo' ~ 'bar' %}
+
+Several variables can be assigned in one block:
+
+.. code-block:: jinja
+
+    {% set foo, bar = 'foo', 'bar' %}
+
+    {# is equivalent to #}
+
+    {% set foo = 'foo' %}
+    {% set bar = 'bar' %}
+
+The ``set`` tag can also be used to 'capture' chunks of text:
+
+.. code-block:: jinja
+
+    {% set foo %}
+        <div id="pagination">
+            ...
+        </div>
+    {% endset %}
+
+.. caution::
+
+    If you enable automatic output escaping, Twig will only consider the
+    content to be safe when capturing chunks of text.
+
+.. note::
+
+    Note that loops are scoped in Twig; therefore a variable declared inside a
+    ``for`` loop is not accessible outside the loop itself:
+
+    .. code-block:: jinja
+
+        {% for item in list %}
+            {% set foo = item %}
+        {% endfor %}
+
+        {# foo is NOT available #}
+
+    If you want to access the variable, just declare it before the loop:
+
+    .. code-block:: jinja
+
+        {% set foo = "" %}
+        {% for item in list %}
+            {% set foo = item %}

+.. tip::
+
+    If you want to optimize the size of the generated HTML content, gzip
+    compress the output instead.
+
+.. tip::

+    (think of ``textarea`` or ``pre`` tags for instance). Using a third-party
+    library like Tidy is probably a better idea.
+
+.. tip::

+``use``
+=======
+
+.. versionadded:: 1.1
+    Horizontal reuse was added in Twig 1.1.
+
+.. note::
+
+    Horizontal reuse is an advanced Twig feature that is hardly ever needed in
+    regular templates. It is mainly used by projects that need to make
+    template blocks reusable without using inheritance.
+
+Template inheritance is one of the most powerful Twig's feature but it is
+limited to single inheritance; a template can only extend one other template.
+This limitation makes template inheritance simple to understand and easy to
+debug:
+
+.. code-block:: jinja
+
+    {% extends "base.html" %}
+
+    {% block title %}{% endblock %}
+    {% block content %}{% endblock %}
+
+Horizontal reuse is a way to achieve the same goal as multiple inheritance,
+but without the associated complexity:
+
+.. code-block:: jinja
+
+    {% extends "base.html" %}
+
+    {% use "blocks.html" %}
+
+    {% block title %}{% endblock %}
+    {% block content %}{% endblock %}
+
+The ``use`` statement tells Twig to import the blocks defined in
+```blocks.html`` into the current template (it's like macros, but for blocks):
+
+.. code-block:: jinja
+
+    # blocks.html
+    {% block sidebar %}{% endblock %}
+
+In this example, the ``use`` statement imports the ``sidebar`` block into the
+main template. The code is mostly equivalent to the following one (the
+imported blocks are not outputted automatically):
+
+.. code-block:: jinja
+
+    {% extends "base.html" %}
+
+    {% block sidebar %}{% endblock %}
+    {% block title %}{% endblock %}
+    {% block content %}{% endblock %}
+
+.. note::
+
+    The ``use`` tag only imports a template if it does not extend another
+    template, if it does not define macros, and if the body is empty. But it
+    can *use* other templates.
+
+.. note::
+
+    Because ``use`` statements are resolved independently of the context
+    passed to the template, the template reference cannot be an expression.
+
+The main template can also override any imported block. If the template
+already defines the ``sidebar`` block, then the one defined in ``blocks.html``
+is ignored. To avoid name conflicts, you can rename imported blocks:
+
+.. code-block:: jinja
+
+    {% extends "base.html" %}
+
+    {% use "blocks.html" with sidebar as base_sidebar %}
+
+    {% block sidebar %}{% endblock %}
+    {% block title %}{% endblock %}
+    {% block content %}{% endblock %}
+
+.. versionadded:: 1.3
+    The ``parent()`` support was added in Twig 1.3.
+
+The ``parent()`` function automatically determines the correct inheritance
+tree, so it can be used when overriding a block defined in an imported
+template:
+
+.. code-block:: jinja
+
+    {% extends "base.html" %}
+
+    {% use "blocks.html" %}
+
+    {% block sidebar %}
+        {{ parent() }}
+    {% endblock %}
+
+    {% block title %}{% endblock %}
+    {% block content %}{% endblock %}
+
+In this example, ``parent()`` will correctly call the ``sidebar`` block from
+the ``blocks.html`` template.
+
+.. tip::
+
+    In Twig 1.2, renaming allows you to simulate inheritance by calling the
+    "parent" block:
+
+    .. code-block:: jinja
+
+        {% extends "base.html" %}
+
+        {% use "blocks.html" with sidebar as parent_sidebar %}
+
+        {% block sidebar %}
+            {{ block('parent_sidebar') }}
+        {% endblock %}
+
+.. note::
+
+    You can use as many ``use`` statements as you want in any given template.
+    If two imported templates define the same block, the latest one wins.

+Twig for Template Designers
+===========================
+
+This document describes the syntax and semantics of the template engine and
+will be most useful as reference to those creating Twig templates.
+
+Synopsis
+--------
+
+A template is simply a text file. It can generate any text-based format (HTML,
+XML, CSV, LaTeX, etc.). It doesn't have a specific extension, ``.html`` or
+``.xml`` are just fine.
+
+A template contains **variables** or **expressions**, which get replaced with
+values when the template is evaluated, and **tags**, which control the logic
+of the template.
+
+Below is a minimal template that illustrates a few basics. We will cover the
+details later on:
+
+.. code-block:: html+jinja
+
+    <!DOCTYPE html>
+    <html>
+        <head>
+            <title>My Webpage</title>
+        </head>
+        <body>
+            <ul id="navigation">
+            {% for item in navigation %}
+                <li><a href="{{ item.href }}">{{ item.caption }}</a></li>
+            {% endfor %}
+            </ul>
+
+            <h1>My Webpage</h1>
+            {{ a_variable }}
+        </body>
+    </html>
+
+There are two kinds of delimiters: ``{% ... %}`` and ``{{ ... }}``. The first
+one is used to execute statements such as for-loops, the latter prints the
+result of an expression to the template.
+
+IDEs Integration

+
+* *Textmate* via the `Twig bundle`_
+* *Vim* via the `Jinja syntax plugin`_
+* *Netbeans* via the `Twig syntax plugin`_ (until 7.1, native as of 7.2)
+* *PhpStorm* (native as of 2.1)
+* *Eclipse* via the `Twig plugin`_
+* *Sublime Text* via the `Twig bundle`_
+* *GtkSourceView* via the `Twig language definition`_ (used by gedit and other projects)
+* *Coda* and *SubEthaEdit* via the `Twig syntax mode`_
+* *Coda 2* via the `other Twig syntax mode`_
+* *Komodo* and *Komodo Edit* via the Twig highlight/syntax check mode
+* *Notepad++* via the `Notepad++ Twig Highlighter`_
+* *Emacs* via `web-mode.el`_
+
+Variables
+---------
+
+The application passes variables to the templates you can mess around in the
+template. Variables may have attributes or elements on them you can access
+too. How a variable looks like heavily depends on the application providing
+those.
+
+You can use a dot (``.``) to access attributes of a variable (methods or
+properties of a PHP object, or items of a PHP array), or the so-called
+"subscript" syntax (``[]``):
+
+.. code-block:: jinja
+
+    {{ foo.bar }}
+    {{ foo['bar'] }}
+
+When the attribute contains special characters (like ``-`` that would be
+interpreted as the minus operator), use the ``attribute`` function instead to
+access the variable attribute:
+
+.. code-block:: jinja
+
+    {# equivalent to the non-working foo.data-foo #}
+    {{ attribute(foo, 'data-foo') }}
+
+.. note::
+
+    It's important to know that the curly braces are *not* part of the
+    variable but the print statement. If you access variables inside tags
+    don't put the braces around.
+
+If a variable or attribute does not exist, you will get back a ``null`` value
+when the ``strict_variables`` option is set to ``false``, otherwise Twig will
+throw an error (see :ref:`environment options<environment_options>`).
+
+.. sidebar:: Implementation
+
+    For convenience sake ``foo.bar`` does the following things on the PHP
+    layer:
+
+    * check if ``foo`` is an array and ``bar`` a valid element;
+    * if not, and if ``foo`` is an object, check that ``bar`` is a valid property;
+    * if not, and if ``foo`` is an object, check that ``bar`` is a valid method
+      (even if ``bar`` is the constructor - use ``__construct()`` instead);
+    * if not, and if ``foo`` is an object, check that ``getBar`` is a valid method;
+    * if not, and if ``foo`` is an object, check that ``isBar`` is a valid method;
+    * if not, return a ``null`` value.
+
+    ``foo['bar']`` on the other hand only works with PHP arrays:
+
+    * check if ``foo`` is an array and ``bar`` a valid element;
+    * if not, return a ``null`` value.
+
+.. note::
+
+    If you want to get a dynamic attribute on a variable, use the
+    :doc:`attribute<functions/attribute>` function instead.
+
+Global Variables
+~~~~~~~~~~~~~~~~
+
+The following variables are always available in templates:
+
+* ``_self``: references the current template;
+* ``_context``: references the current context;
+* ``_charset``: references the current charset.
+
+Setting Variables
+~~~~~~~~~~~~~~~~~
+
+You can assign values to variables inside code blocks. Assignments use the
+:doc:`set<tags/set>` tag:
+
+.. code-block:: jinja
+
+    {% set foo = 'foo' %}
+    {% set foo = [1, 2] %}
+    {% set foo = {'foo': 'bar'} %}
+
+Filters
+-------
+
+Variables can be modified by **filters**. Filters are separated from the
+variable by a pipe symbol (``|``) and may have optional arguments in
+parentheses. Multiple filters can be chained. The output of one filter is
+applied to the next.
+
+The following example removes all HTML tags from the ``name`` and title-cases
+it:
+
+.. code-block:: jinja
+
+    {{ name|striptags|title }}
+
+Filters that accept arguments have parentheses around the arguments. This
+example will join a list by commas:
+
+.. code-block:: jinja
+
+    {{ list|join(', ') }}
+
+To apply a filter on a section of code, wrap it with the
+:doc:`filter<tags/filter>` tag:
+
+.. code-block:: jinja
+
+    {% filter upper %}
+      This text becomes uppercase
+    {% endfilter %}
+
+Go to the :doc:`filters<filters/index>` page to learn more about the built-in
+filters.
+
+Functions
+---------
+
+Functions can be called to generate content. Functions are called by their
+name followed by parentheses (``()``) and may have arguments.
+
+For instance, the ``range`` function returns a list containing an arithmetic
+progression of integers:
+
+.. code-block:: jinja
+
+    {% for i in range(0, 3) %}
+        {{ i }},
+    {% endfor %}
+
+Go to the :doc:`functions<functions/index>` page to learn more about the
+built-in functions.
+
+Named Arguments
+---------------
+
+.. versionadded:: 1.12
+    Support for named arguments was added in Twig 1.12.
+
+Arguments for filters and functions can also be passed as *named arguments*:
+
+.. code-block:: jinja
+
+    {% for i in range(low=1, high=10, step=2) %}
+        {{ i }},
+    {% endfor %}
+
+Using named arguments makes your templates more explicit about the meaning of
+the values you pass as arguments:
+
+.. code-block:: jinja
+
+    {{ data|convert_encoding('UTF-8', 'iso-2022-jp') }}
+
+    {# versus #}
+
+    {{ data|convert_encoding(from='iso-2022-jp', to='UTF-8') }}
+
+Named arguments also allow you to skip some arguments for which you don't want
+to change the default value:
+
+.. code-block:: jinja
+
+    {# the first argument is the date format, which defaults to the global date format if null is passed #}
+    {{ "now"|date(null, "Europe/Paris") }}
+
+    {# or skip the format value by using a named argument for the timezone #}
+    {{ "now"|date(timezone="Europe/Paris") }}
+
+You can also use both positional and named arguments in one call, in which
+case positional arguments must always come before named arguments:
+
+.. code-block:: jinja
+
+    {{ "now"|date('d/m/Y H:i', timezone="Europe/Paris") }}
+
+.. tip::
+
+    Each function and filter documentation page has a section where the names
+    of all arguments are listed when supported.
+
+Control Structure
+-----------------
+
+A control structure refers to all those things that control the flow of a
+program - conditionals (i.e. ``if``/``elseif``/``else``), ``for``-loops, as
+well as things like blocks. Control structures appear inside ``{% ... %}``
+blocks.
+
+For example, to display a list of users provided in a variable called
+``users``, use the :doc:`for<tags/for>` tag:
+
+.. code-block:: jinja
+
+    <h1>Members</h1>
+    <ul>
+        {% for user in users %}
+            <li>{{ user.username|e }}</li>
+        {% endfor %}
+    </ul>
+
+The :doc:`if<tags/if>` tag can be used to test an expression:
+
+.. code-block:: jinja
+
+    {% if users|length > 0 %}
+        <ul>
+            {% for user in users %}
+                <li>{{ user.username|e }}</li>
+            {% endfor %}
+        </ul>
+    {% endif %}
+
+Go to the :doc:`tags<tags/index>` page to learn more about the built-in tags.
+
+Comments
+--------
+
+To comment-out part of a line in a template, use the comment syntax ``{# ...
+#}``. This is useful for debugging or to add information for other template
+designers or yourself:
+
+.. code-block:: jinja
+
+    {# note: disabled template because we no longer use this
+        {% for user in users %}
+            ...
+        {% endfor %}
+    #}
+
+Including other Templates
+-------------------------
+
+The :doc:`include<tags/include>` tag is useful to include a template and
+return the rendered content of that template into the current one:
+
+.. code-block:: jinja
+
+    {% include 'sidebar.html' %}
+
+Per default included templates are passed the current context.
+
+The context that is passed to the included template includes variables defined
+in the template:
+
+.. code-block:: jinja
+
+    {% for box in boxes %}
+        {% include "render_box.html" %}
+    {% endfor %}
+
+The included template ``render_box.html`` is able to access ``box``.
+
+The filename of the template depends on the template loader. For instance, the
+``Twig_Loader_Filesystem`` allows you to access other templates by giving the
+filename. You can access templates in subdirectories with a slash:
+
+.. code-block:: jinja
+
+    {% include "sections/articles/sidebar.html" %}
+
+This behavior depends on the application embedding Twig.
+
+Template Inheritance
+--------------------
+
+The most powerful part of Twig is template inheritance. Template inheritance
+allows you to build a base "skeleton" template that contains all the common
+elements of your site and defines **blocks** that child templates can
+override.
+
+Sounds complicated but is very basic. It's easier to understand it by
+starting with an example.
+
+Let's define a base template, ``base.html``, which defines a simple HTML
+skeleton document that you might use for a simple two-column page:
+
+.. code-block:: html+jinja
+
+    <!DOCTYPE html>
+    <html>
+        <head>
+            {% block head %}
+                <link rel="stylesheet" href="style.css" />
+                <title>{% block title %}{% endblock %} - My Webpage</title>
+            {% endblock %}
+        </head>
+        <body>
+            <div id="content">{% block content %}{% endblock %}</div>
+            <div id="footer">
+                {% block footer %}
+                    &copy; Copyright 2011 by <a href="http://domain.invalid/">you</a>.
+                {% endblock %}
+            </div>
+        </body>
+    </html>
+
+In this example, the :doc:`block<tags/block>` tags define four blocks that
+child templates can fill in. All the ``block`` tag does is to tell the
+template engine that a child template may override those portions of the
+template.
+
+A child template might look like this:
+
+.. code-block:: jinja
+
+    {% extends "base.html" %}
+
+    {% block title %}Index{% endblock %}
+    {% block head %}
+        {{ parent() }}
+        <style type="text/css">
+            .important { color: #336699; }
+        </style>
+    {% endblock %}
+    {% block content %}
+        <h1>Index</h1>
+        <p class="important">
+            Welcome to my awesome homepage.
+        </p>
+    {% endblock %}
+
+The :doc:`extends<tags/extends>` tag is the key here. It tells the template
+engine that this template "extends" another template. When the template system
+evaluates this template, first it locates the parent. The extends tag should
+be the first tag in the template.
+
+Note that since the child template doesn't define the ``footer`` block, the
+value from the parent template is used instead.
+
+It's possible to render the contents of the parent block by using the
+:doc:`parent<functions/parent>` function. This gives back the results of the
+parent block:
+
+.. code-block:: jinja
+
+    {% block sidebar %}
+        <h3>Table Of Contents</h3>
+        ...
+        {{ parent() }}
+    {% endblock %}
+
+.. tip::
+
+    The documentation page for the :doc:`extends<tags/extends>` tag describes
+    more advanced features like block nesting, scope, dynamic inheritance, and
+    conditional inheritance.
+
+.. note::
+
+    Twig also supports multiple inheritance with the so called horizontal reuse
+    with the help of the :doc:`use<tags/use>` tag. This is an advanced feature
+    hardly ever needed in regular templates.
+
+HTML Escaping
+-------------
+
+When generating HTML from templates, there's always a risk that a variable
+will include characters that affect the resulting HTML. There are two
+approaches: manually escaping each variable or automatically escaping
+everything by default.
+
+Twig supports both, automatic escaping is enabled by default.
+
+.. note::
+
+    Automatic escaping is only supported if the *escaper* extension has been
+    enabled (which is the default).
+
+Working with Manual Escaping
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+If manual escaping is enabled, it is **your** responsibility to escape
+variables if needed. What to escape? Any variable you don't trust.
+
+Escaping works by piping the variable through the
+:doc:`escape<filters/escape>` or ``e`` filter:
+
+.. code-block:: jinja
+
+    {{ user.username|e }}
+
+By default, the ``escape`` filter uses the ``html`` strategy, but depending on
+the escaping context, you might want to explicitly use any other available
+strategies:
+
+.. code-block:: jinja
+
+    {{ user.username|e('js') }}
+    {{ user.username|e('css') }}
+    {{ user.username|e('url') }}
+    {{ user.username|e('html_attr') }}
+
+Working with Automatic Escaping
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Whether automatic escaping is enabled or not, you can mark a section of a
+template to be escaped or not by using the :doc:`autoescape<tags/autoescape>`
+tag:
+
+.. code-block:: jinja
+
+    {% autoescape %}
+        Everything will be automatically escaped in this block (using the HTML strategy)
+    {% endautoescape %}
+
+By default, auto-escaping uses the ``html`` escaping strategy. If you output
+variables in other contexts, you need to explicitly escape them with the
+appropriate escaping strategy:
+
+.. code-block:: jinja
+
+    {% autoescape 'js' %}
+        Everything will be automatically escaped in this block (using the JS strategy)
+    {% endautoescape %}
+
+Escaping
+--------
+
+It is sometimes desirable or even necessary to have Twig ignore parts it would
+otherwise handle as variables or blocks. For example if the default syntax is
+used and you want to use ``{{`` as raw string in the template and not start a
+variable you have to use a trick.
+
+The easiest way is to output the variable delimiter (``{{``) by using a variable
+expression:
+
+.. code-block:: jinja
+
+    {{ '{{' }}
+
+For bigger sections it makes sense to mark a block
+:doc:`verbatim<tags/verbatim>`.
+
+Macros
+------
+
+.. versionadded:: 1.12
+    Support for default argument values was added in Twig 1.12.
+
+Macros are comparable with functions in regular programming languages. They
+are useful to reuse often used HTML fragments to not repeat yourself.
+
+A macro is defined via the :doc:`macro<tags/macro>` tag. Here is a small example
+(subsequently called ``forms.html``) of a macro that renders a form element:
+
+.. code-block:: jinja
+
+    {% macro input(name, value, type, size) %}
+        <input type="{{ type|default('text') }}" name="{{ name }}" value="{{ value|e }}" size="{{ size|default(20) }}" />
+    {% endmacro %}
+
+Macros can be defined in any template, and need to be "imported" via the
+:doc:`import<tags/import>` tag before being used:
+
+.. code-block:: jinja
+
+    {% import "forms.html" as forms %}
+
+    <p>{{ forms.input('username') }}</p>
+
+Alternatively, you can import individual macro names from a template into the
+current namespace via the :doc:`from<tags/from>` tag and optionally alias them:
+
+.. code-block:: jinja
+
+    {% from 'forms.html' import input as input_field %}
+
+    <dl>
+        <dt>Username</dt>
+        <dd>{{ input_field('username') }}</dd>
+        <dt>Password</dt>
+        <dd>{{ input_field('password', '', 'password') }}</dd>
+    </dl>
+
+A default value can also be defined for macro arguments when not provided in a
+macro call:
+
+.. code-block:: jinja
+
+    {% macro input(name, value = "", type = "text", size = 20) %}
+        <input type="{{ type }}" name="{{ name }}" value="{{ value|e }}" size="{{ size }}" />
+    {% endmacro %}
+
+.. _twig-expressions:
+
+Expressions
+-----------
+
+Twig allows expressions everywhere. These work very similar to regular PHP and
+even if you're not working with PHP you should feel comfortable with it.
+
+.. note::
+
+    The operator precedence is as follows, with the lowest-precedence
+    operators listed first: ``b-and``, ``b-xor``, ``b-or``, ``or``, ``and``,
+    ``==``, ``!=``, ``<``, ``>``, ``>=``, ``<=``, ``in``, ``..``, ``+``,
+    ``-``, ``~``, ``*``, ``/``, ``//``, ``%``, ``is``, ``**``, ``|``, ``[]``,
+    and ``.``:
+
+    .. code-block:: jinja
+
+        {% set greeting = 'Hello' %}
+        {% set name = 'Fabien' %}
+
+        {{ greeting ~ name|lower }}   {# Hello fabien #}
+
+        {# use parenthesis to change precedence #}
+        {{ (greeting ~ name)|lower }} {# hello fabien #}
+
+Literals
+~~~~~~~~
+
+.. versionadded:: 1.5
+    Support for hash keys as names and expressions was added in Twig 1.5.
+
+The simplest form of expressions are literals. Literals are representations
+for PHP types such as strings, numbers, and arrays. The following literals
+exist:
+
+* ``"Hello World"``: Everything between two double or single quotes is a
+  string. They are useful whenever you need a string in the template (for
+  example as arguments to function calls, filters or just to extend or include
+  a template). A string can contain a delimiter if it is preceded by a
+  backslash (``\``) -- like in ``'It\'s good'``.
+
+* ``42`` / ``42.23``: Integers and floating point numbers are created by just
+  writing the number down. If a dot is present the number is a float,
+  otherwise an integer.
+
+* ``["foo", "bar"]``: Arrays are defined by a sequence of expressions
+  separated by a comma (``,``) and wrapped with squared brackets (``[]``).
+
+* ``{"foo": "bar"}``: Hashes are defined by a list of keys and values
+  separated by a comma (``,``) and wrapped with curly braces (``{}``):
+
+  .. code-block:: jinja
+
+    {# keys as string #}
+    { 'foo': 'foo', 'bar': 'bar' }
+
+    {# keys as names (equivalent to the previous hash) -- as of Twig 1.5 #}
+    { foo: 'foo', bar: 'bar' }
+
+    {# keys as integer #}
+    { 2: 'foo', 4: 'bar' }
+
+    {# keys as expressions (the expression must be enclosed into parentheses) -- as of Twig 1.5 #}
+    { (1 + 1): 'foo', (a ~ 'b'): 'bar' }
+
+* ``true`` / ``false``: ``true`` represents the true value, ``false``
+  represents the false value.
+
+* ``null``: ``null`` represents no specific value. This is the value returned
+  when a variable does not exist. ``none`` is an alias for ``null``.
+
+Arrays and hashes can be nested:
+
+.. code-block:: jinja
+
+    {% set foo = [1, {"foo": "bar"}] %}
+
+.. tip::
+
+    Using double-quoted or single-quoted strings has no impact on performance
+    but string interpolation is only supported in double-quoted strings.
+
+Math
+~~~~
+
+Twig allows you to calculate with values. This is rarely useful in templates
+but exists for completeness' sake. The following operators are supported:
+
+* ``+``: Adds two objects together (the operands are casted to numbers). ``{{
+  1 + 1 }}`` is ``2``.
+
+* ``-``: Subtracts the second number from the first one. ``{{ 3 - 2 }}`` is
+  ``1``.
+
+* ``/``: Divides two numbers. The returned value will be a floating point
+  number. ``{{ 1 / 2 }}`` is ``{{ 0.5 }}``.
+
+* ``%``: Calculates the remainder of an integer division. ``{{ 11 % 7 }}`` is
+  ``4``.
+
+* ``//``: Divides two numbers and returns the truncated integer result. ``{{
+  20 // 7 }}`` is ``2``.
+
+* ``*``: Multiplies the left operand with the right one. ``{{ 2 * 2 }}`` would
+  return ``4``.
+
+* ``**``: Raises the left operand to the power of the right operand. ``{{ 2 **
+  3 }}`` would return ``8``.
+
+Logic
+~~~~~
+
+You can combine multiple expressions with the following operators:
+
+* ``and``: Returns true if the left and the right operands are both true.
+
+* ``or``: Returns true if the left or the right operand is true.
+
+* ``not``: Negates a statement.
+
+* ``(expr)``: Groups an expression.
+
+.. note::
+
+    Twig also support bitwise operators (``b-and``, ``b-xor``, and ``b-or``).
+
+Comparisons
+~~~~~~~~~~~
+
+The following comparison operators are supported in any expression: ``==``,
+``!=``, ``<``, ``>``, ``>=``, and ``<=``.
+
+Containment Operator
+~~~~~~~~~~~~~~~~~~~~
+
+The ``in`` operator performs containment test.
+
+It returns ``true`` if the left operand is contained in the right:
+
+.. code-block:: jinja
+
+    {# returns true #}
+
+    {{ 1 in [1, 2, 3] }}
+
+    {{ 'cd' in 'abcde' }}
+
+.. tip::
+
+    You can use this filter to perform a containment test on strings, arrays,
+    or objects implementing the ``Traversable`` interface.
+
+To perform a negative test, use the ``not in`` operator:
+
+.. code-block:: jinja
+
+    {% if 1 not in [1, 2, 3] %}
+
+    {# is equivalent to #}
+    {% if not (1 in [1, 2, 3]) %}
+
+Test Operator
+~~~~~~~~~~~~~
+
+The ``is`` operator performs tests. Tests can be used to test a variable against
+a common expression. The right operand is name of the test:
+
+.. code-block:: jinja
+
+    {# find out if a variable is odd #}
+
+    {{ name is odd }}
+
+Tests can accept arguments too:
+
+.. code-block:: jinja
+
+    {% if loop.index is divisibleby(3) %}
+
+Tests can be negated by using the ``is not`` operator:
+
+.. code-block:: jinja
+
+    {% if loop.index is not divisibleby(3) %}
+
+    {# is equivalent to #}
+    {% if not (loop.index is divisibleby(3)) %}
+
+Go to the :doc:`tests<tests/index>` page to learn more about the built-in
+tests.
+
+Other Operators
+~~~~~~~~~~~~~~~
+
+.. versionadded:: 1.12.0
+    Support for the extended ternary operator was added in Twig 1.12.0.
+
+The following operators are very useful but don't fit into any of the other
+categories:
+
+* ``..``: Creates a sequence based on the operand before and after the
+  operator (this is just syntactic sugar for the :doc:`range<functions/range>`
+  function).
+
+* ``|``: Applies a filter.
+
+* ``~``: Converts all operands into strings and concatenates them. ``{{ "Hello
+  " ~ name ~ "!" }}`` would return (assuming ``name`` is ``'John'``) ``Hello
+  John!``.
+
+* ``.``, ``[]``: Gets an attribute of an object.
+
+* ``?:``: The ternary operator:
+
+  .. code-block:: jinja
+
+      {{ foo ? 'yes' : 'no' }}
+
+      {# as of Twig 1.12.0 #}
+      {{ foo ?: 'no' }} == {{ foo ? foo : 'no' }}
+      {{ foo ? 'yes' }} == {{ foo ? 'yes' : '' }}
+
+String Interpolation
+~~~~~~~~~~~~~~~~~~~~
+
+.. versionadded:: 1.5
+    String interpolation was added in Twig 1.5.
+
+String interpolation (`#{expression}`) allows any valid expression to appear
+within a *double-quoted string*. The result of evaluating that expression is
+inserted into the string:
+
+.. code-block:: jinja
+
+    {{ "foo #{bar} baz" }}
+    {{ "foo #{1 + 2} baz" }}
+
+Whitespace Control
+------------------
+
+.. versionadded:: 1.1
+    Tag level whitespace control was added in Twig 1.1.
+
+The first newline after a template tag is removed automatically (like in PHP.)
+Whitespace is not further modified by the template engine, so each whitespace
+(spaces, tabs, newlines etc.) is returned unchanged.
+
+Use the ``spaceless`` tag to remove whitespace *between HTML tags*:
+
+.. code-block:: jinja
+
+    {% spaceless %}
+        <div>
+            <strong>foo bar</strong>
+        </div>
+    {% endspaceless %}
+
+    {# output will be <div><strong>foo bar</strong></div> #}
+
+In addition to the spaceless tag you can also control whitespace on a per tag
+level. By using the whitespace control modifier on your tags, you can trim
+leading and or trailing whitespace:
+
+.. code-block:: jinja
+
+    {% set value = 'no spaces' %}
+    {#- No leading/trailing whitespace -#}
+    {%- if true -%}
+        {{- value -}}
+    {%- endif -%}
+
+    {# output 'no spaces' #}
+
+The above sample shows the default whitespace control modifier, and how you can
+use it to remove whitespace around tags.  Trimming space will consume all whitespace
+for that side of the tag.  It is possible to use whitespace trimming on one side
+of a tag:
+
+.. code-block:: jinja
+
+    {% set value = 'no spaces' %}
+    <li>    {{- value }}    </li>
+
+    {# outputs '<li>no spaces    </li>' #}
+
+Extensions
+----------
+
+Twig can be easily extended.
+
+If you are looking for new tags, filters, or functions, have a look at the Twig official
+`extension repository`_.
+
+If you want to create your own, read the :ref:`Creating an
+Extension<creating_extensions>` chapter.

+    constant now accepts object instances as the second argument.
+
+``constant`` checks if a variable has the exact same value as a constant. You

+.. code-block:: jinja
+
+    {% if post.status is constant('Post::PUBLISHED') %}
+        the status attribute is exactly the same as Post::PUBLISHED

+    {% if post.status is constant('PUBLISHED', post) %}
+        the status attribute is exactly the same as Post::PUBLISHED

+
+When using the ``defined`` test on an expression that uses variables in some

+
+.. code-block:: jinja
+
+    {% if var is defined and foo.method(var) is defined %}

+ * This exception class and its children must only be used when
+ * an error occurs during the loading of a template, when a syntax error
+ * is detected in a template, or when rendering a template. Other
+ * errors must use regular PHP exception classes (like when the template
+ * cache directory is not writable for instance).
+ *
+ * To help debugging template issues, this class tracks the original template
+ * name and line where the error occurred.
+ *
+ * Whenever possible, you must set these information (original template name
+ * and line number) yourself by passing them to the constructor. If some or all
+ * these information are not available from where you throw the exception, then
+ * this class will guess them automatically (when the line number is set to -1
+ * and/or the filename is set to null). As this is a costly operation, this
+ * can be disabled by passing false for both the filename and the line number
+ * when creating a new instance of this class.

+Twig Gettext Extractor [![Build Status](https://secure.travis-ci.org/umpirsky/Twig-Gettext-Extractor.png?branch=master)](http://travis-ci.org/umpirsky/Twig-Gettext-Extractor)
+======================
+
+The Twig Gettext Extractor is [Poedit](http://www.poedit.net/download.php)
+friendly tool which extracts translations from twig templates.
+
+## Installation
+
+The recommended way to install Twig Gettext Extractor is through
+[composer](http://getcomposer.org).
+
+```json
+{
+    "require": {
+        "umpirsky/twig-gettext-extractor": "1.1.*"
+    }
+}
+```
+
+## Setup
+
+By default, Poedit does not have the ability to parse Twig templates.
+This can be resolved by adding an additional parser (Edit > Preferences > Parsers)
+with the following options:
+
+- Language: `Twig`
+- List of extensions: `*.twig`
+- Invocation:
+    - Parser command: `<project>/vendor/bin/twig-gettext-extractor --sort-output --force-po -o %o %C %K -L PHP --files %F`
+    - An item in keyword list: `-k%k`
+    - An item in input file list: `%f`
+    - Source code charset: `--from-code=%c`
+
+<img src="http://i.imgur.com/f9px2.png" />
+
+Now you can update your catalog and Poedit will synchronize it with your twig
+templates.
+
+## Tests
+
+To run the test suite, you need [composer](http://getcomposer.org) and
+[PHPUnit](https://github.com/sebastianbergmann/phpunit).
+
+    $ composer install --dev
+    $ phpunit
+
+## License
