Jupyter Notebook overrides user Mathjax settings from custom.js

sindzicat commented 5 years ago

Hello!

I found recently that my settings for Mathjax stopped to work.

It seems to me I understand correctly why.

When the web page of Jupyter Notebook is loading we load Mathjax first:

<script type="text/javascript" src="/static/components/MathJax/MathJax.js?config=TeX-AMS-MML_HTMLorMML-full,Safe&delayStartupUntil=configured" charset="utf-8"></script>

I see StartupUntil=configured at the end. According documentation this means that Mathjax will wait instrtuction MathJax.Hub.Configured().

I found such instruction only in one file — mathjaxutils.js (code line).

Then I found that mathjaxutils.js are called by script main.min.js at the end of <body>. File mathjaxutils.js contains own MathJax.Hub.Config, that called after user MathJax.Hub.Config from custom.js. So user settings for Mathjax will be overriden.

Of course I can change local mathjaxutils.js after installation and even write own python script that will watch this file... But it's not a good way. Please fix this.

Sorry, I found how to solve my problem.

In custom.js you need to use

MathJax.Hub.Config({
    tex2jax: {
        inlineMath: [["$", "$"], ["\\(", "\\)"]],
        displayMath: [["$$", "$$"], ["\\[", "\\]"]],
        processEscapes: true,
    },
    TeX: {
        Macros: {
            Alpha: "\\mbox{A}",
            Beta: "\\mbox{B}",
            Epsilon: "\\mbox{E}",
            Zeta: "\\mbox{Z}",
            Eta: "\\mbox{H}",

            deg: "\\unicode{xb0}",    // degree sign
            celdeg: "\\unicode{x2103}"   // degree Celsius sign
        },
        // AutoNumbering of displayed formulas
        equationNumbers: { autoNumber: "AMS" },
        // All mathjax extensions:

            "AMSmath.js",
            "AMSsymbols.js",
            "AMScd.js", // http://www.jmilne.org/not/Mamscd.pdf

            "cancel.js" // support for strikethrough formulas
            // "HTML.js" // works by default
            // "mhchem.js" // chemical formulas
            // "uniconde.js" // works by default
        ]
    }
});
// http://docs.mathjax.org/en/latest/configuration.html#configuring-mathjax-after-it-is-loaded
MathJax.Hub.Configured()

The last line MathJax.Hub.Configure() must be presented. Now all works for me fine. The only I cannot understand — why this didn't work yesterday???

Hm... After page reload doesn't work again...

sindzicat commented 5 years ago

I tried to add

TeX: {
    Macros: {
        tg: "\\operatorname{tg}"
    }
}

to main.min.js in MathJax.Hub.Config. Now \tg(x) works fine. But why only after that hack?

Is anybody here?
