t|_|S(s+This decorator can be used to mark a function or method context callable.
    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|_|S(sGThis decorator can be used to mark a function or method as an eval
    context callable.  This is similar to the :func:`contextfunction`
    but instead of passing the context, an evaluation context object is
    passed.  For more information about the eval context, see
    :ref:`eval-context`.

    filename of the template.  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.

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.  In that case single
    quote your attributes or HTML escape it in addition.
