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 Truet contextfunction( t f( ( s0 /usr/lib/python2.7/site-packages/jinja2/utils.pyR s c C s t | _ | S( sG This decorator can be used to mark a function or method as an eval context callable.

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 | j d � j � Vq d S( R' N( t lstript lower( Rn R ( ( s0 /usr/lib/python2.7/site-packages/jinja2/utils.pys <genexpr># s c s s( | ] } d | j d � j � Vq d S( R' N( R� R� ( Rn R ( ( s0 /usr/lib/python2.7/site-packages/jinja2/utils.pys <genexpr>% s c sF | d k r � S| j � } | j � � r/ t S| j � � rB t S� S( N( R, R� RW R Rs ( t template_name( R� t default_for_stringt disabled_patternst enabled_patterns( s0 /usr/lib/python2.7/site-packages/jinja2/utils.pyt autoescape' s ( R� ( t enabled_extensionst disabled_extensionsR� R� R� ( ( R� R� R� R� s0 /usr/lib/python2.7/site-packages/jinja2/utils.pyt select_autoescape� s & c K sa | d k r t j } n | | | � j d d � j d d � j d d � j d d � } t | � S( s� Works exactly like :func:`dumps` but is safe for use in ``<script>`` tags. 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.
