Math formula support ?

[waynenilsen]

Great work with this project! I would love to see mathjax or katex integration. I use math formulas frequently and pandoc supports this. Here is a render from pandoc with mathjax integration

and the same thing in mdbook

I am using them in parallel for this reason right now.

I would love that too ;) Actually that is one of the features I want most, because I plan to use mdBook for my school notes. But the best place to implement this is in the markdown parser (pulldown-cmark). There is already a request there, but it's not very active.

I added the MathJax JS files (from the CDN) you can already add math equations but sometimes it collides with the markdown rules, for example:
*$$ 1 * 2 + 3 = 5 $$ works but *$$1*2+3=5$$ does not.

Yea, I agree that it should be in the markdown parser. As a workaround you could sanitize the MD by replacing the math with random, non-repeating characters a-z and keeping a lookup table, then putting the math back into the generated HTML. Maybe there is an easier way?

At the moment, it should work using:

Blocks

\\[ Your math here... \\]

Inline

\\( Your math here... \\)

You have to double-escape, because the markdown parser is going to remove one backslash. I have used this and I haven't had any problems. The dollar signs do not work well and would need support in the markdown parser.
