Don't use MathJax when creating epub versions about modelicabook HOT 4 CLOSED

Sorry I misread the information on MathJax and epub. The linked article above actually says that MathML is part of epub3 but not MathJax. MathJax could just be used to circumvent the lack of MathML in the readers per day. That is if the reader can load in and use MathJax.js

I might have found the solution. Including a local copy of MathJax under _static and linking that one instead of the CDN version will also include MathJax in the epub version. Mind MathJax is not really a small package. The size of the epub with static MathJax is about 17 MB vs. 1.5 MB with png images for math equations/symbols.

Anyway what's needed is to put the MathJax sources (174MB btw) under _static/MathJax and to add the following lines to conf.py:

 # Use local copy of MathJax (necessary for epub)
 mathjax_path = 'MathJax/MathJax.js?config=TeX-AMS-MML_HTMLorMML'

Adding the sources should be done via git subtree.

Mind, I have not yet tested if the epub version with static MathJax actually work. This depends of course on the epub reader. I will test this tonight. The calbre viewer should also display MathJax (Plugin which now seems to be part of calibre). In the Plugin link there is also a link to a post on how to slim down mathjax for usage in epub.

The example epub containing MathJax from the calibre page works fine but our current version of ModelicaBook as epub does not. Need to investigate further.

Turns out that at least on my Kobo Touch ebook reader not even the example mathjax.epub from the calibre page is not rendered. So I guess we should stick to dvipng created images for equations.
