Math not rendered without network connection (Windows)

[ajj]

Testing on Windows 7, a lack of network connection means that the math in the documentation does not get rendered.

On the Mac, it is still being rendered even without a network connection.

I thought that mathjax was being bundled, so this should be working.

MathJax can be shipped with SasView.

We need to add _static/MathJax to the doc tree, with the following files from the MathJax distribution (776 kB):

    MathJax.js
    config/TeX-AMS-MML_HTMLorMML-full.js
    fonts/HTML-CSS/TeX/woff/*
    jax/output/HTML-CSS/fonts/TeX/*

The html header needs the following:

    <script type="text/x-mathjax-config">
    MathJax.Hub.Config({
      "HTML-CSS": {
        //undefinedFamily: ["STIXGeneral, 'Arial Unicode MS', serif"],
        preferredFont: "TeX",
        availableFonts: ["TeX"],
        webFont: "TeX",
        imageFont: null
      }
    });
    </script>
    </script>
    <script type="text/javascript" src="../../_static/MathJax/MathJax.js?config=TeX-AMS-MML_HTMLorMML-full"></script>

maybe best to move to 4.1? We could provide a PDF downladable somewhere?

This is slightly more convoluted. On my windows box I need to also add

fonts/HTML-CSS/TeX/eot/*

Also,

extensions/

is required if we want to enable right-click context menu, as in the online version.
It is possible than on other machines/systems/OSes we need to add more subdirectories in fonts/*

Obviously adding everything is not an option, as uncompressed MathJax? is 172MB.

​https://github.com/mathjax/MathJax-grunt-cleaner/blob/master/Gruntfile.js

seems to be the "official" way to do this - clone the repo and run grunt. However, this is yet another lot of infrastructure.

If it is all local, we should probably just have a script to pull in the right bits and update occasionally as mathjax changes.

a bit annoying when no network is available but not a show stopper and needs a bit more care than 2 days before a release — moving to 4.1

[butler]

Didn't get addressed at code camp so moving to 4.2

19th Oct 2016, on my windows 7 desktop, the equations in the docu are rendering only slowly if at all. Before they do render a message pops up briefly at bottom on docu screen which says:

File failed to load: ​https://cdn.mathjax.org/mathjax/contrib/a11y/accessibility-menu.js

Is this a different issue to the above, or is it just flaky web access here?

From #948 …

Longer term, need to replace mathjax with katex, which is faster and smaller and easier to bundle with the application. This is closer to working on Qt than it is in wx.
