Re: [sage-devel] No MathJax display in Sage 10.3.beta notebooks when offline

[Dima Pasechnik]

My experiments with a pure upstream jupyterlab show that this is not 
reproducible there.
Namely:
1) clean up cache of your browser
2) create a fresh venv and pip install jupyterlab there, and the 
corresponding mathjax package:

$ python3 -m venv foo
$. foo/bin/activate
(foo) $ pip install jupyterlab
(foo) $ pip install jupyterlab-mathjax3

3) Disconnect the internet. Launch notebook

(foo) $ jupyterlab textest.ipynb # attached

4) Try evaluating cells (they all show nice mathjax - probably from a 
system package, but certainly not from a CDN)

-

IMHO it's yet another reason for stopping to vendor Jupyter(lab), and just 
using what's readily provided by the pure upstream!

jupyter is javascript, and its MathJax config is essentially a js script
which one puts into html files
inside  tags. Generation of this html happens whenever a
notebook is rendered, so there should be a template somewhere with this js
script.

In https://github.com/jupyter/notebook/blob/main/notebook/app.py#L89 one has
mathjax_url = self.settings.get(...)

being defaulted to a CDN, if an env.var. "mathjax_url" is not set. And
after that line you see code which looks like generation of an html page.

I believe the answer is somewhere in
https://github.com/jupyterlab/jupyterlab/issues/9911
(but now it's 1am here, and I'm lost there :-))

Well, the text in the tip looks more like config file content than 
javascript, so whoever wrote the tip probably didn't propose to change 
javascript. Supposedly, they had a config file in mind somewhere, which 
would not be minified. I have very limited knowledge of the configuration

The snippet looks like this:

Hopefully jupyter can provide a more obvious way to tweak this option, but

The notebook release process minifies all of its javascript code. The

Re: [sage-devel] No MathJax display in Sage 10.3.beta notebooks when offline

[Nils Bruin]

According to the jupyter notebook documentation:

https://jupyterbook.org/en/stable/content/math.html

it should be possible to switch jupyter from using mathjax 2 to mathjax 3 
by some configuration option (no clue where those configuration options 
would go, and no indication is given in the tip either). I would think that 
if one can switch to a different mathjax by just changing a URL in the 
config, one should be able to point that at local resources (a "file:" URL 
instead) to avoid any use of https, and hence hopefully the internet.

I'd be interested in hearing if someone figures out how to do that, since 
on my own (system) jupyter mathjax is severely hobbled: at some point 
jupyter decided to ship a stripped-down mathjax, so I don't get any 
dedicated mathfont goodness; only unicode approximations. I've tried to 
convince the server to use proper mathjax but failed. The jupyter server 
that comes packaged with sagemath does work well -- a small case where 
we're getting a benefit from sage-the-distribution.

Ideally, this should be possible to specify in the Sage's Jupyter kernel, how 
you want MathJax for the notebooks set up.

As this is the only (?) regular way to communicate the wishes about a class of 
notebooks to the Jupiter(lab) server.

I am sure it is configurable, just as well as you can configure delimiters used

OK, thanks for the feedback!  Hence this is not a Ubuntu-specific issue. 
 

It seems that jupyterlab(notebook 7) only uses mathjax cdn. (As far as I

Thanks for reminding me about this. Then I guess the question is: why 
Jupyterlab in Sage 10.3.beta8 is using MathJax 2.7.7 (available only 
online) and not the system's MathJax (2.7.9) ? Again, there was no such 
issue with Sage 10.2.

The partial conclusion is thus: 

- Sage 10.2 uses Ubuntu 22.04's MathJax (v2.7.9), so there is no issue when

Sage's MathJax 3.2.0 is definitely installed in my Sage 10.3.beta8 root 
tree for if I look at the locally generated reference manual (i.e. 
local/share/doc/sage/html/en/reference/index.html), the math formulas there 
are rendered by MathJax 3.2.0 (as one can see by right-clicking on them and 
selecting "About MathJax"); this works even in the offline mode.

So it appears that Sage's MathJax 3.2.0 is used for the documentation but 
not for Jupyter/Jupyterlab notebooks.

Re: [sage-devel] No MathJax display in Sage 10.3.beta notebooks when offline

[Dima Pasechnik]

That's why we should just stop shipping jupyterlab, and instead use one offered 
by the OS or some other standard Jupyter way. 

Here we are trying to solve already solved problems, what's the point of it?

[sage-devel] No MathJax display in Sage 10.3.beta notebooks when offline

[Eric Gourgoulhon]

Hi,

While working on a Sage 10.3.beta  notebook in a train without any internet 
connection, I've noticed that there is no LaTeX rendering via MathJax, 
neither in the markdown cells nor in the output cells within the scope of  
%display latex. There is no such issue with Sage 10.2 and I've opened 
https://github.com/sagemath/sage/issues/36914
for this. 

Apparently, the problem arises with Ubuntu 22.04, but not with macOS. It 
would be nice to have more tests, possibly on various OS, to identify the 
issue. Thanks for your feedback!

Eric.
