This may not recognize links in some situations. Usually, a more comprehensive formatter, such as a Markdown library, is a better choice. Works on ``http://``, ``https://``, ``www.``, ``mailto:``, and email addresses. Links with trailing punctuation (periods, commas, closing parentheses) and leading punctuation (opening parentheses) are recognized excluding the punctuation. Email addresses that include header fields are not recognized (for example, ``mailto:address@example.com?cc=copy@example.com``). :param text: Original text containing URLs to link. :param trim_url_limit: Shorten displayed URL values to this length. :param target: Add the ``target`` attribute to links. :param rel: Add the ``rel`` attribute to links. :param extra_schemes: Recognize URLs that start with these schemes in addition to the default behavior. .. versionchanged:: 3.0 The ``extra_schemes`` parameter was added. .. versionchanged:: 3.0 Generate ``https://`` links for URLs without a scheme. .. versionchanged:: 3.0 The parsing rules were updated. Recognize email addresses with or without the ``mailto:`` scheme. Validate IP addresses. Ignore parentheses and brackets in more cases.

This is the recommended way to configure autoescaping if you do not want to write a custom function yourself. If you want to enable it for all templates created from strings or for all templates with `.html` and `.xml` extensions:: from jinja2 import Environment, select_autoescape env = Environment(autoescape=select_autoescape( enabled_extensions=('html', 'xml'), default_for_string=True, )) Example configuration to turn it on at all times except if the template ends with `.txt`:: from jinja2 import Environment, select_autoescape env = Environment(autoescape=select_autoescape( disabled_extensions=('txt',), default_for_string=True, default=True, )) The `enabled_extensions` is an iterable of all the extensions that autoescaping should be enabled for. Likewise `disabled_extensions` is a list of all templates it should be disabled for. If a template is loaded from a string then the default from `default_for_string` is used. If nothing matches then the initial value of autoescaping is set to the value of `default`. For security reasons this function operates case insensitive. .. versionadded:: 2.9 c s s" | ]}d |� d ��� � �V qdS )rJ N)�lstrip�lower)r� r r r r r� � s z$select_autoescape.<locals>.<genexpr>c s s" | ]}d |� d ��� � �V qdS )rJ N)r� r� )r� r r r r r� � s )� template_namer c s4 | d kr �S | � � } | ���r"dS | ���r0dS � S )NTF)r� ry )r� )r� r� �disabled_patterns�enabled_patternsr r � autoescape� s z%select_autoescape.<locals>.autoescape)r� r4 r5 rq r� )r� r� r� r� r� r )r� r� r� r� r �select_autoescape� s ( r� )r �dumps�kwargsr c K s@ |dkrt j}t�|| f|��dd��dd��dd��dd ��S ) a� Serialize an object to a string of JSON with :func:`json.dumps`, then replace HTML-unsafe characters with Unicode escapes and mark the result safe with :class:`~markupsafe.Markup`. This is available in templates as the ``|tojson`` filter. The following characters are escaped: ``<``, ``>``, ``&``, ``'``.

The exception is in HTML attributes that are double quoted; either use single quotes or the ``|forceescape`` filter. :param obj: The object to serialize to JSON. :param dumps: The ``dumps`` function to use.
