Syntax highlight Markdown formulas using LaTeX highlighting

Question

I often write non-trivial mathematical formulas inside Markdown documents, and having them syntax-highlighted would really help.

In Markdown, LaTeX math formulae are denoted: $x^2$ and $$x^2$$, and are escaped as \$x\$and \$\$x\$\$.

Markdown math formulas are rendered via MathJax (to match future googlers' keywords).

If I use vim-markdown to syntax highlight the Markdown, how can I use vimtex to syntax highlight only the text inside the formulae?

Note: I only want the text inside $ to be treated differently if the filetype is markdown or foobar (future proofing against my lack of VimL).

Bonus: I'd like the $ delimiters themselves to use the syntax highlight group Statement.

Hints:

I think these are along the right path, but I couldn't work out how the solution from them:

• Perhaps vim-SyntaxRange would help. (I couldn't work out how to set it up with the delimiters.)
• vim wikia's Different syntax highlighting within regions of a file

• This code:

  " Block math. Look for "$$[anything]$$"
  syn region math start=/\$\$/ end=/\$\$/
  " Inline math. Look for "$[not $][anything]$"
  syn match math_block '\$[^$].\{-}\$'
  

Answer 1

I don't use vim-Markdown, but just by skimming over its readme, I found its syntax extension for LaTeX math

Used as $x^2$, $$x^2$$, escapable as \$x\$ and \$\$x\$\$.

let g:vim_markdown_math = 1

The plugin code uses :syntax include of the tex syntax, just like you also could do with my vim-SyntaxRange plugin.
