Class AttrsDirective

object --+    
 Directive --+

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="">
...   <li py:attrs="foo">Bar</li>
... </ul>''')
>>> print(tmpl.generate(foo={'class': 'collapse'}))
  <li class="collapse">Bar</li>
>>> print(tmpl.generate(foo=[('class', 'collapse')]))
  <li class="collapse">Bar</li>

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

>>> print(tmpl.generate(foo=None))
