Mathjax
Jason Grout
I don't know if you've seen the recent activity on including mathjax in
the Sage notebook, but I think we're almost there (finally!). I spent
the last few days reviewing the current progress, making lots more
changes, and putting up a test server at test.sagenb.org. For example,
http://test.sagenb.org/home/pub/20/ is a public worksheet using MathJax.
I have a couple of questions, though:
1. Can you subscribe me (jason...@creativetrax.com) to the MathJax
users mailing list? Apparently I cannot subscribe a non-google address.
2. I specified in the config file these two options:
imageFont: null,
MathMenu: {
showFontMenu: true
}
However, the fonts menu still shows the image TeX fonts as an option.
Worse yet, when I select it, MathJax shows that it is trying to download
images, fails, then displays a red error message. Then there is no way
for me to get back to a menu to change my font choice anymore. It would
be great if right-clicking on the error message popped up the mathjax menu.
3. Is there any way to get the little box at the bottom of the page that
we had with jsmath, where we could click on it to get a MathJax menu?
Unfortunately, right-clicking on expressions doesn't work with the ipad,
for example.
4. Is there a way we can set things to default to a local TeX font, then
a web TeX font, instead of the STIX fonts? There have been some people
that complained that the STIX fonts were not as pretty.
The thread about this final testing stage for mathjax is here:

(also here:
http://groups.google.com/group/sage-notebook/browse_thread/thread/3af7717ce44ce3ac)
Thanks again for all of your help with this,
Jason

I've been reading the docs again, and I just realized that (and am
half-way through testing it). I'm glad to know I'm thinking correctly.
Another question: in Firefox 9.0.1 on OSX 10.6.8, it seems (i.e., the
option is selected in the menu) that the default is to use HTML-CSS
instead of MML, which seems to go contrary to what
http://www.mathjax.org/docs/1.1/options/MMLorHTML.html says.

That's good to know it will default back to unicode.

Great!

Okay. Maybe we'll look at writing something in the short term. Can we
manipulate the options from javascript?

Given the tradeoff, we'll probably vote on this issue. Thanks for
telling us how to do either way.

Thanks again for your help! I'm sorry I didn't catch some of these
answers in the (nicely written!) docs before emailing you.

Interesting. Even when I switch to Private mode in FF 9.0.1, then
specifically clear the mathjax.org cookies, the menu on
http://www.mathjax.org/demos/tex-samples/ shows that I am using HTML-CSS
instead of MathML.
Thanks,
Jason

Thanks for the tip! I'll set our notebook to always use HTML-CSS as
well, then.
Thanks!
