Re: [sage-devel] MathJax limit for TeX expression in notebook
Hi Thierry,
Using SageManifolds, I can produce long equations quite easily - for
testing
I also decreased the value of MAXBUFFER in
$SAGE_ROOT/local/share/mathjax/config/TeX-AMS_HTML-full.js
(javascript file used by ipython notebook) from 5*1024 to 128. Then I have
%display latex
M = Manifold(2,'M')
X. = M.chart()
h = M.scalar_field(function('h',x,y))
dh = h.differential()
dh.display() # works
(dh*dh).display() # is too long and not rendered properly
Btw. I'm a little baffled at the moment, because the following works fine
m = matrix(QQ, 16, 16, lambda i, j: i+j)
latex(m)
Cheers,
Michał

+1 to this. What is the best course of action? Opening a ticket?

[sage-devel] MathJax limit for TeX expression in notebook
Dear Sage Devs, I have a question related to the limited length of a TeX expression rendered by MathJax in the notebook - the variable responsible for it is MAXBUFFER [1], and its default value is 5*1024 (5KB), which in most cases is quite all right but sometimes, for example when printing tensor components in SageManifolds (sagemanifolds.obspm.fr), it's not enough. Is it possible to pass a MathJax preamble in the notebook? Or alternatively, can we have MAXBUFFER increased in Sage local/share/mathjax/config/TeX-AMS_HTML-full.js default configuration?

[sage-devel] Custom derivative output from pynac
Dear all,
I was wondering about a way to get a custom derivative output,
that is more readable for an end-user. For example, in pynac.pyx,
py_print_fderivative() returns the operator as
ostr = ''.join(['D[', ', '.join([repr(int(x)) for x in params]), ']'])
whereas it would be nice to have
ostr = ''.join(['D_{', ', '.join([repr(args[int(x)]) for x in params]),
'}'])
What is a recommended way to get such a custom output from
a level of an external package?
Best regards,
Michal
