Support inserted LaTex formulas

[MPCBexplorer]

Initial checklist

• I read the support docs
• I read the contributing guide
• I agree to follow the code of conduct
• I searched issues and discussions and couldn’t find anything (or linked relevant results below)

Problem

I used the latex formula when writing a blog in VScode, but mdx didn't have the corresponding support, so I searched for issues on GitHub and found [Issue#504] (#504 added remark-math , but the same problem as Issue#504 still exists; I make sure I'm using the latest version of the plugin
I'm wondering if mdx treats latex's {} as JS, maybe we could add $..$ syntax and treat the content as a formula and skip the JS syntax check of the content

Current solutions

Maybe no existing solutions right now

Proposed solutions

Add $..$ syntax to treat formula

I need a minimal reproduction.

[MPCBexplorer]

• IDE：VScode
• Main plugins：Astro ，MDX，remark
• sample：

• .remarkrc.mjs:

  export default {
    plugins: [
      'remark-math', 
    ]
  };

[remcohaszing]

A minimal reproduction means a repository I can clone and investigate. Also .remarkrc.mjs is unrelated.

Hi! Thanks for taking the time to contribute! This has been marked by a maintainer as needing a reproduction: It’s not yet clear whether this is a problem. Here are a couple tips:

• Thoroughly document how to reproduce the problem, in steps or with code
• Don’t link to your complete project: make the repro as tiny as possible, preferrably with only the problematic project in question
• Make sure you’re on the latest versions of projects (and node/npm/yarn!)
• The best issue report is a failing test proving it

Thanks,

Clone this repo https://github.com/MPCBexplorer/mdx-latex-repro
You might notice some display issues in vscode.
Please forgive my ignorance, and if there is anything lacking, don't be angry and point it out to me

[remcohaszing]

Sorry if I came across angry. That’s not my intention.

You need to specify remark-math in the mdx.plugins list in tsconfig.json as documented in https://github.com/mdx-js/mdx-analyzer#plugins. You also need to make sure remark-math is installed in your node_modules.
