class Render(ttag.helpers.AsTag):
    """
    A block tag that renders its contents to a context variable.

    Here is an example of using it with a ``blocktrans`` tag::

        {% render as name %}
            <a href="{{ profile.get_absolute_url }}">{{ profile }}</a>
        {% endrender %}
        {% blocktrans %}Logged in as {{ name }}{% endblocktrans %}

    Here is an example of a simple base template that leverages this tag to
    avoid duplication of a page title::

        {% render as title %}
            {% block title %}The page title{% endblock %}
        {% endrender %}

        <html>
        <head><title>{{ title }}</title></head>
        <body>
            <h1>{{ title }}</h1>
            {% block body %}{% endblock %}
        </body>

    By default, the tag strips the output of leading and trailing white space.
    To avoid this, use the ``no_strip`` argument::

        {% render no_strip as target %} ... {% endrender %}
    """
    no_strip = ttag.BooleanArg()

    class Meta():
        block = True

    def as_value(self, data, context):
        output = self.nodelist.render(context)
        if 'no_strip' not in data:
            output = output.strip()
        return mark_safe(output)
