Jason --
Thanks for quick followup. I'm not sure what it would mean for me
to "publish" such
a worksheet, since students will not have any access to any of my pages.
(In fact, in the
lab, I myself won't have any worksheets.)
Also, perhaps I'm a little dense, but am new to this setup. When
you say have the
students "execute"
with open(os.path.join(os.environ['DOT_SAGE'], 'init.sage'), 'w') as
f:
f.write('gap._....')
. . . where and how do they execute this? (It is a language I do not
recognize. Sage?
Python?). I would certainly prefer *not* to instruct students to enter
such a
complicated obscure command without explanation (I prefer my students to
understand
everything they enter), and it is so complicated that many of them are
likely to enter it
incorrectly creating havoc.
It would be better to change the original .sage directory to contain
the init.sage, if I can
get that method to work and figure out how to get it into their .sage
directory when they
start up initially.
The underlying issue here that you may not understand is that the
students are working
in a lab in which every machine is totally wiped each evening. I have
managed to find a way
for students to save and restore their ".sage" directory to a very small
cloud storage space,
so they can restore their work when they return, but otherwise they start
over each day.
Thanks!
