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.x,y = 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

Hi,
it is doable, especially since the bound on MAXBUFFER seems to aim only at
avoiding infinite loops.
Could you please send an easy way to produce such huge formula in Sage so
that i can test further ?
Ciao,
Thierry

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?
Best regards,
Michał

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

In principle you should be able to just hardcode a different value in in your own notebook server. I suspect my students are hitting the same issue from time to time when working on optimization problems, I just had no idea how it can be fixed. What is the downside of increasing this buffer to say 10 or 20 kilobytes? My understanding is that the same MathJax is now shared by all frontends, so improvements will affect everybody!

[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
