Duplicating discussion here, since it looks like feasible through Mmark, which has been adopted recently.
From Mmark README:
- Math support, use
$$as the delimiter. If the math is part of a paragraph it will
be displayed inline, if the entire paragraph consists out of math it considered display
math. No attempt is made to parse what is between the$$.
Is this already working? What are the steps to use Mmark and have this enabled?
If it's OK for being used, I guess the official hugo docs about MathJax support could be updated with this information.
If it's not working, I'd propose for the issue to keep open (in case it's not a "won't fix") to target enabling it for Mmark.
