No, but I also think that is not necessary, but something similar could
prove useful:
@environmentfilter
def css_classes(env, classes):
return u' '.join(unicode(x) for x in classes if x) \
or env.undefined(hint='No classes requested')
env.filters['css_classes'] = css_classes
And then you can use it like this:
Simple case:
<td class="{{ ['foo', 'bar']|css_classes }}">
--> <td class="foo bar">
Conditional case:
<td class="{{ ['foo', 'bar' if true, 'baz' if false]|css_classes }}">
--> <td class="foo bar">
With XML attributes:
<td{{ dict(class=['foo', 'bar' if true, 'baz'
if false]|css_classes)|xmlattr }}>
--> <td class="foo bar">
With XML attributes and nothing left:
<td{{ dict(class=['baz' if false]|css_classes)|xmlattr }}>
--> <td>
Hope that filter is helpful.
Regards,
Armin
