Code blocks in HTML comments were incorrectly converted about hexo

[FZQ0003]

I have found the reason.
This issue (typing markdown fenced code blocks in html comments) only appears when I enable one of built-in syntax highlight libraries. In my old environment, I disabled them and use Prettify instead, and it worked well.
I'll use another highlighter.

By the way, I have read an article about code blocks https://hexo.io/docs/syntax-highlight.html#How-to-use-code-block-in-posts. It says code block syntax will always be available, so I did additional tests.

Syntax highlighting is disabled.

Source:

Text 1

<!--

Commented text 1

{% codeblock %}
A commented code block
{% endcodeblock %}

Commented text 2

-->

Text 2

Output:

<p>Text 1</p>
<!--

Commented text 1

<pre><code>A commented code block</code></pre>

<p>Commented text 2</p>
<p>–&gt;</p>
<p>Text 2</p>

...
</html>-->

I should edit the title.

hexo wraps the highlighting code in <! -- --> and passes it into the markdown renderer, making it difficult to deal with nested comments.

hexo/lib/hexo/post.ts

Line 42 in 3c7729d

return `<!--${flag}\uFFFC${cache.push(str) - 1}-->`;

Notice that the end of the comment is escaped as <p>-&gt;</p>, causing a comment tag pairing failure.
