+``format``
+==========
+
+The ``format`` filter formats a given string by replacing the placeholders
+(placeholders follows the `sprintf`_ notation):
+
+.. code-block:: jinja
+
+ {{ "I like %s and %s."|format(foo, "bar") }}
+
+ {# outputs I like foo and bar
+ if the foo parameter equals to the foo string. #}
