Comment(by wcauchois):
I did some work to alleviate this issue, including implementing a new
displayhook. The displayhook looks at every list, and if any object's repr
spans multiple lines it prints the whole list out in a special format. See
for yourself:
{{{
sage: list(MatrixSpace(GF(2),2))
[
[0 0] [1 0] [0 1] [0 0] [0 0] [1 1] [1 0] [1 0] [0 1] [0 1]
[0 0], [0 0], [0 0], [1 0], [0 1], [0 0], [1 0], [0 1], [1 0], [0 1],
[0 0] [1 1] [1 1] [1 0] [0 1] [1 1]
[1 1], [1 0], [0 1], [1 1], [1 1], [1 1]
]
}}}
I discovered that IPython has a separate displayhook mechanism -- however,
the Sage instance spawned for the notebook does not use IPython. Hence, my
code has two separate paths. I tried to ensure that the behavior of the
default displayhook would be maintained in any case. I do hope it doesn't
break anything :).
