Revision history [back]

A week or so ago, I spent quite a lot of time with some sagecell code, but it no longer seems to work.

In particular, if I ran the following code on aleph:

@interact def f(denominator=2): print "denominator must be an even integer" assert type(denominator) == Integer assert denominator % 2 == 0 @interact(controls=[('t', (-1/2,1,1/denominator))]) def s(multiplier=2, **kwargs): assert multiplier > 0 print kwargs.keys()

I would now get an empty list, whereas a week or 10 days ago, I got 't'. As a result, my code is now irretrievably broken.

What changed and how can I either fix it or restore the old version?
