A generator cannot be resumed while it is actively running

[banesiu.sever@…]

There are at least 2 generator errors:

>>> from genshi.builder import Element
>>> e = Element('p')
>>> e(e)
<Element "p">
>>> print e
Traceback (most recent call last):

>>> from genshi.builder import Element
>>> e = Element('p')
>>> s = e.generate()
>>> e(s)
<Element "p">
>>> print e
Traceback (most recent call last):

Do you have a real-world case where this happens? Looks like wrong use of the API to me.

[anonymous]

Why is it a wrong use of the API? If you can append a fragment to another one why is it wrong to append the same fragment to itself? If you have a fragment that you want to repeat multiple times, why build the same fragment multiple times when you can build it once and append it to itself?

[mgood]

Fragments can be repeated, that's not a problem:

>>> d = Element('div')(Element('p'))
>>> print d + d
<div><p/></div><div><p/></div>

Adding an element as a child of itself becomes recursive, so I don't think there's a reasonable way to handle this, nor a good reason to do so.

Closing this based on previous comments by Matt and myself.
