A context callable is passed the active :class:`Context` as first argument when called from the template. This is useful if a function wants to get access to the context or functions provided on the context object. For example a function that returns a sorted list of template variables the current template exports could look like this:: @contextfunction def get_exported_names(context): return sorted(context.exported_vars) T)�contextfunction��fr r r r # s r c C s d| _ | S )aG This decorator can be used to mark a function or method as an eval context callable.

An import path can be specified either in dotted notation (``xml.sax.saxutils.escape``) or with a colon as object delimiter (``xml.sax.saxutils:escape``).

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 �r.

It accepts the same arguments and returns a JSON string. Note that this is available in templates through the ``|tojson`` filter which will also mark the result as safe. Due to how this function escapes certain characters this is safe even if used outside of ``<script>`` tags. The following characters are escaped in strings: - ``<`` - ``>`` - ``&`` - ``'`` This makes it safe to embed such strings in any place in HTML with the notable exception of double quoted attributes. In that case single quote your attributes or HTML escape it in addition.
