Original GitHub issue: https://github.com/DavidAnson/markdownlint/issues/166

I write markdown file with LaTeX like this style:

## Hello World.

$$
\gcd(a, b) = \gcd(b, a \% b)
$$$$
\gcd(a, b) = \gcd(b, a \% b)
$$

And MDlint just scans no synatx warning with this file. When I add one or more lines after $$, the extension works again. So it's a bug or a real problem to write LaTeX with more than one line and using $$$$?

What syntax errors are you expecting?

Also, please note that this project doesn’t recognize math blocks by default – though the VS Code markdownlint extension does.

Yeah... I'm using VS Code but I go to this repository, maybe because of the errors showing?

Let it to be a md file and there is no first heading. (002, 041, 026 for '.' punctuation) But they can't show with latex blocks and show without them or with more lines.

I’m afraid I still don’t understand. Going back to your original example file above, what errors are you expecting to be reported on what lines? Or else what errors are you seeing reported that you do not think are correct?

It should be reported as

[1,1] MD002/first-heading-h1/first-header-h1: First heading should be a top level heading [Expected: h1; Actual: h2]
[1,1] MD041/first-line-h1: First line in file should be a top level heading
[1,1] MD026/no-trailing-punctuation: Trailing punctuation in heading [Punctuation: '.']

But with latex block below and no more empty lines at EOF, it can't be shown.

$$
Some math expressions

It looks to be a bug in markdownlint related to the way the math block parser outputs tokens. I can't reproduce it otherwise. Good catch, thank you!
