autoescape

Whether automatic escaping is enabled or not, you can mark a section of a template to be escaped or not by using the autoescape tag:

{% autoescape %}
    Everything will be automatically escaped in this block
    using the HTML strategy
{% endautoescape %}

{% autoescape 'html' %}
    Everything will be automatically escaped in this block
    using the HTML strategy
{% endautoescape %}

{% autoescape 'js' %}
    Everything will be automatically escaped in this block
    using the js escaping strategy
{% endautoescape %}

{% autoescape false %}
    Everything will be outputted as is in this block
{% endautoescape %}

When automatic escaping is enabled everything is escaped by default except for values explicitly marked as safe. Those can be marked in the template by using the raw filter:

{% autoescape %}
    {{ safe_value|raw }}
{% endautoescape %}

Functions returning template data (like macros and parent) always return safe markup.

{% set hello = "<strong>Hello</strong>" %}
{{ hello }}
{{ "<strong>world</strong>" }}
