            AttrsDirective

Implementation of the py:attrs template directive.

The value of the py:attrs attribute should be a dictionary or a sequence of (name, value) tuples. The items in that dictionary or sequence are added as attributes to the element:

>>> from genshi.template import MarkupTemplate
>>> tmpl = MarkupTemplate('''<ul xmlns:py="http://genshi.edgewall.org/">
...   <li py:attrs="foo">Bar</li>
... </ul>''')
>>> print tmpl.generate(foo={'class': 'collapse'})
<ul>
  <li class="collapse">Bar</li>
</ul>
>>> print tmpl.generate(foo=[('class', 'collapse')])
<ul>
  <li class="collapse">Bar</li>
</ul>

If the value evaluates to None (or any other non-truth value), no attributes are added:

>>> print tmpl.generate(foo=None)
<ul>
  <li>Bar</li>
</ul>
