-
-Backward incompatibilities:

-   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 priority to node visitors
-
-* 0.9.9 (2010-11-28)
-
-Backward incompatibilities:
- * the self special variable has been renamed to _self

-     {{ 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 }})
-

- * 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 Twig_Template::getAttribute() for protected properties
-
-* 0.9.8 (2010-06-28)
-
-Backward incompatibilities:

-
-* 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

- * 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 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
- * changed the filter tag to allow chained filters
- * 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
- * enhanced some error messages to ease debugging
- * fixed empty cache files when the template contains an error
-
-* 0.9.1 (2009-10-14)
-
-  * fixed a bug in PHP 5.2.6
-  * fixed numbers with one than one decimal
-  * added support for method calls with arguments ({{ foo.bar('a', 43) }})
-  * made small speed optimizations
-  * made minor tweaks to allow better extensibility and flexibility
-
-* 0.9.0 (2009-10-12)
-
- * Initial release

-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 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:
-
-========== ========================== ========== =========================
-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);
-    $twig->addGlobal('text', new Text());
-
-You can then use the ``text`` variable anywhere in a template:
-
-.. code-block:: jinja
-
-    {{ text.lipsum(40) }}
-
-Filters
--------
-
-A filter is a regular PHP function or an object method that takes the left
-side of the filter (before the pipe ``|``) as first argument and the extra
-arguments passed to the filter (within parentheses ``()``) as extra arguments.
-
-Defining a filter is as easy as associating the filter name with a PHP
-callable. For instance, let's say you have the following code in a template:
-
-.. code-block:: jinja
-
-    {{ 'TWIG'|lower }}
-
-When compiling this template to PHP, Twig looks for the PHP callable
-associated with the ``lower`` filter. The ``lower`` filter is a built-in Twig
-filter, and it is simply mapped to the PHP ``strtolower()`` function. After
-compilation, the generated PHP code is roughly equivalent to:
-
-.. code-block:: html+php
-
-    <?php echo strtolower('TWIG') ?>
-
-As you can see, the ``'TWIG'`` string is passed as a first argument to the PHP
-function.
-
-A filter can also take extra arguments like in the following example:
-
-.. code-block:: jinja
-
-    {{ now|date('d/m/Y') }}
-
-In this case, the extra arguments are passed to the function after the main
-argument, and the compiled code is equivalent to:
-
-.. code-block:: html+php
-
-    <?php echo twig_date_format_filter($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
-  following class and interface will be removed in 2.0:
-
-  * ``Twig_TokenParserBrokerInterface``
-  * ``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
--------
-
-* As of Twig 1.x, use ``Twig_SimpleFilter`` to add a filter. The following
-  classes and interfaces will be removed in 2.0:
-
-  * ``Twig_FilterInterface``
-  * ``Twig_FilterCallableInterface``
-  * ``Twig_Filter``
-  * ``Twig_Filter_Function``
-  * ``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:
-

-``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

-    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] %}
-        {# ... #}
-    {% endfor %}
-
-    {{ '12345'[1:2] }}
-
-    {# you can omit the first argument -- which is the same as 0 #}
-    {{ '12345'[:2] }} {# will display "12" #}
-
-    {# 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.
-
-Arguments
----------
-
- * ``start``:         The start of the slice
- * ``length``:        The size of the slice
- * ``preserve_keys``: Whether to preserve key or not (when the input is an array)

-``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.

-.. 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

-``parent``
-==========
-
-When a template uses inheritance, it's possible to render the contents of the
-parent block when overriding a block by using the ``parent`` function:
-
-.. code-block:: jinja
-
-    {% extends "base.html" %}
-
-    {% block sidebar %}
-        <h3>Table Of Contents</h3>
-        ...
-        {{ parent() }}
-    {% endblock %}
-
-The ``parent()`` call will return the content of the ``sidebar`` block as
-defined in the ``base.html`` template.

-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::
-
-    require_once '/path/to/vendor/autoload.php';
-
-.. note::
-
-    Twig follows the PEAR convention names for its classes, which means you
-    can easily integrate Twig classes loading in your own autoloader.
-
-.. code-block:: php
-
-    $loader = new Twig_Loader_String();
-    $twig = new Twig_Environment($loader);
-
-    echo $twig->render('Hello {{ name }}!', array('name' => 'Fabien'));
-
-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',
-    ));
-
-    echo $twig->render('index.html', array('name' => 'Fabien'));

-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 'html' %}
-        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 outputted as is in this block
-        {% endautoescape %}
-
-        {% autoescape true js %}
-            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.

-``embed``
-=========
-
-.. versionadded:: 1.8
-    The ``embed`` tag was added in Twig 1.8.
-
-The ``embed`` tag combines the behaviour of :doc:`include<include>` and
-:doc:`extends<extends>`.
-It allows you to include another template's contents, just like ``include``
-does. But it also allows you to override any block defined inside the
-included template, like when extending a template.
-
-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" #}

-        {% 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 ─────────────────────┐
-    │                                     │

-    │           │  put content here)  │   │

-
-Some pages ("foo" and "bar") share the same content structure -
-two vertically stacked boxes:
-

-two boxes side by side:

-
-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
-

-        {% block bottom %}

-
-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 %}
-

-
-.. 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 ``..``

-
-.. 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 %}
-

-.. 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 %}
-            <li>{{ key }}: {{ user.username|e }}</li>
-        {% endfor %}
-    </ul>
-
-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.

-``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

-.. code-block:: jinja
-
-    {% sandbox %}
-        {% include 'user.html' %}

-
-        {% sandbox %}
-            {% for i in 1..2 %}
-                {{ i }}

-``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 %}
-        {% endfor %}
-

-``spaceless``
-=============
-
-Use the ``spaceless`` tag to remove whitespace *between HTML tags*, not
-whitespace within HTML tags or whitespace in plain text:
-
-.. code-block:: jinja
-
-    {% spaceless %}
-        <div>

-        </div>

-    {# output will be <div><strong>foo</strong></div> #}
-
-This tag is not meant to "optimize" the size of the generated HTML content but
-merely to avoid extra whitespace between HTML tags to avoid browser rendering
-quirks under some circumstances.
-
-.. tip::
-
-    If you want to optimize the size of the generated HTML content, gzip
-    compress the output instead.
-
-.. tip::
-
-    If you want to create a tag that actually removes all extra whitespace in
-    an HTML string, be warned that this is not as easy as it seems to be
-    (think of ``textarea`` or ``pre`` tags for instance). Using a third-party
-    library like Tidy is probably a better idea.
-
-.. tip::
-
-    For more information on whitespace control, read the
-    :doc:`dedicated<../templates>` section of the documentation and learn how
-    you can also use the whitespace control modifier on your tags.

-``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.

-============

-    {% endverbatim %}
-

-

-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
-----------------
-
-Many IDEs support syntax highlighting and auto-completion for Twig:
-
-* *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.

-/**
- * Twig base exception.
- *
- * 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.
