Yup, that's very similar to a solution I came up with. Just checking that
there isn't a pre-existing method or function I missed. Think I'll go write
an enhancement ticket at sage trac. :/

I've opened an enhancement ticket here:
http://trac.sagemath.org/sage_trac/ticket/12554
and given you the credit for the example implementation. My approach used a
dictionary, but your implementation has the advantage that if an earlier
test returns True, the additional test logic doesn't have
Hi Rob, you understand more than I do - is this a bug (big step of
time needed for that type of calculation at an rather arbitrary
number)? Should I create a track ticket for that? Do you have also an
opinion on the various other points?
Actually, the cutoff changed:

Hi all !
I want sage -t to test my docstrings.
Here is my example :

# -*- coding: utf8 -*-
from sage.all import *
def my_function(a):
EXAMPLE ::
sage: my_function(3)

I don't know about whether this behavior has changed recently, but as
far as I know, `sage -t` doesn't currently work on files that are not in
the Sage library directory. This is not ideal and people were talking
about trying to fix it recently:

Really? I doubt it.
Your doc test will work if and only if my_function is defined in
sage.all if and only if my_function is available directly after

Yes, really ;)
Well, in fact I did not tested THAT example on Sage 4.7, but my usual
programs had doctrings that were working on 4.7 and
But what if I don't want to add from ... import * at the beginning of each

I had this issue recently. William informed me that the philosophy of
doctests is that a user should be able to take anything they see in a
doctest and type it directly into sage with no additional commands.

So once it comes back to Sage, its internal representation goes back to the
Ginac one.
Doh! So much for a possible workaround involving maxima.
Dox, I was using full_simplify() and also the handful of simplify
methods it invokes. Evaluate a.full_simplify? to see their names.

I recently upgraded to sage 4.8 and was working on some older
notebooks. Something has changed in Sage, I can no longer get
show($P_{integral}$) to work properly. This should type set to P
with subscript of integral. What am I doing wrong?
