Custom extensions are bound to an environment but may not store environment specific data on `self`. The reason for this is that an extension can be bound to another environment (for overlays) by creating a copy and reassigning the `environment` attribute. As extensions are created by the environment they cannot accept any arguments for configuration. One may want to work around that by using a factory function, but that is not possible as extensions are identified by their import name. The correct way to configure the extension is storing the configuration values on the environment. Because this way the environment ends up acting as central configuration storage the attributes may clash which is why extensions have to ensure that the names they choose for configuration are not too generic. ``prefix`` for example is a terrible name, ``fragment_cache_prefix`` on the other hand is a good name as includes the name of the extension (fragment cache). � identifierr Nc C s | j � d| j� �| _d S )N�.)r r r+ )�clsr r r �__init_subclass__L � zExtension.__init_subclass__�tags�d � environmentc C s || _ d S r )r2 �r r2 r r r �__init__Y s zExtension.__init__c C s, t �tt�| j��}|j�| j� ||_|S )z=Create a copy of this extension bound to another environment.) �t�castr* �object�__new__� __class__�__dict__�updater2 )r r2 �rvr r r �bind\ s zExtension.bind�source�name�filenamec C � |S )z�This method is called before the actual lexing and can be used to preprocess the source.

Per default this function returns matches in babel style that means non string parameters as well as keyword arguments are returned as `None`. This allows Babel to figure out what you really meant if you are using gettext functions that allow keyword arguments for placeholder expansion. If you don't want that behavior set the `babel_style` parameter to `False` which causes only strings to be returned and parameters are always stored in tuples. As a consequence invalid gettext calls (calls without a single string parameter or string parameters after non-string parameters) are skipped. This example explains the behavior: >>> from jinja2 import Environment >>> env = Environment() >>> node = env.parse('{{ (_("foo"), _(), ngettext("foo", "bar", 42)) }}') >>> list(extract_from_ast(node)) [(1, '_', 'foo'), (1, '_', ()), (1, 'ngettext', ('foo', 'bar', None))] >>> list(extract_from_ast(node, babel_style=False)) [(1, '_', ('foo',)), (1, 'ngettext', ('foo', 'bar'))] For every string found this function yields a ``(lineno, function, message)`` tuple, where: * ``lineno`` is the number of the line on which the string was found, * ``function`` is the name of the ``gettext`` function used (if the string was extracted from embedded Python code), and * ``message`` is the string, or a tuple of strings for functions with multiple string arguments. This extraction function operates on the AST and is because of that unable to extract any comments. For comment support you have to use the babel extraction interface or extract comments yourself.
