Hi all.
I've messed around with the wiki, too. Check out the expanded frontpage
that I've taken to. Thoughts on that while I continue with it?
I also have started removing some of the specific SPKG pages in order to
keep it all on one wiki.sagemath.org/spkg page. That would help with trying
to k
This is not what you are proposing but somehow related to it: provided you
consider (x,y) as coordinates on a manifold, you may define g as a named
function as follows:
sage: M = Manifold(2, 'M')
sage: X. = M.chart() # declares the chart X on M, with coordinates
(x,y)
sage: g = M.scalar_field
Instead of adding another %display option, why not fix the standard
%display typeset? If mathjax can't display some object then it just
shouldn't display using mathjax in jupyter.

Hi,
In case anybody cares, I'm doing a complete rewrite of the Jupyter
frontend client from scratch (and also using nteract's node.js backend
instead of the python backend). Thanks for mentioning some
missing/desired features, e.g., customizability of a "typeset"
checkbox. If anybody else has
Hi,
log(1+x).limit(x=-1)
returns Infinity, but should return -Infinity. It seems that the sympy
algorithm solves this issue. Is this a known bug?
Note also that `dir='+'` solves this, but the docs say that leaving
`dir=None` should compute the two-sided limit (so perhaps a ValueError
should b

Hello to all,
At the moment we need transform a symbolic expression from 'sage' to
'sympy',
for explicit functions, sage works fine :
sage: b = sin(x)
sage: type(b)
sage: type(sin)
sage: a=b._sympy_()
sin(x)
sage: type(a)
sin # this is strange!
and viceversa
import sympy
sage: x=sym

To add on Travis post, some rationale for having default LaTeX typeset
outputs in the Jupyter notebook is
- Jupyter is scheduled to be the default notebook in Sage 8.0
- It is likely that users (especially beginners) who employ the notebook
instead of the console are expecting to have "nice" outp

Thanks for pointing right files. I opened #22661 for this and also put in

Sure, but it will take some changes to the parser. Currently the #long tag
only affects whether the test is added to the list of tests to be run.
Once that has been decided, the fact that a test was marked with #long is
currently not stored anywhere. The place you'll need to change is line 566

Is it possible to modify doctesting framework to have different time for
tests marked with # long time? Something like sage --warn-long 1,10 could
give warning for only doctests taking more than 10 seconds if they are
explicitly marked as slow.
