Hexo-theme-next: How to disable selection for Dollar signs in Markdown code blocks

[xu-song]

I agree and want to create new issue

• [x] Yes, I was on Hexo Docs page, especially on Templates, Variables, Helpers and Troubleshooting.
• [x] Yes, I was on NexT Documentation Site.
• [x] And yes, I already searched for current issues and this is not help to me.

Actual behavior

In common, if you select all in the code block, the $ will be included.

Expected behavior

How can I get the style like @ivan-nginx?

Add the following css might work:

pre .bash_symbol {
  user-select: none;
  -webkit-user-select: none;    
  -moz-user-select: none;
  -ms-user-select: none;
}

[xu-song]

thanks. Actually, css is not the key point.
The main issue might be the code block render.

In ivan's pages

<code class="bash">
  <span class="bash_symbol">$ </span>
  <span class="built_in">yum</span>
   install vsftpd
</code>

default render

The default render is tomorrow-theme

# Code Highlight theme
# https://github.com/chriskempson/tomorrow-theme
highlight_theme: normal

In the default render, I get the following output

<td class="code">
  <pre>
    <span class="line">
      $ hexo new 
      <span class="string">"My New Post"</span>
    </span>
  </pre>
</td>

Yes, it's need to do in Hexo javascript file + NexT css files. I actually don't remember what i edit for that, but i can find it and want to try implement this feature in NexT or in Hexo with option on it.

Feature look's like this:

In MD file:

    yum install vsftpd

Will automatically render in HTML to:

Try this:

$(".line").each(function(i, o) {
    str = $(o).html();
    if (str.substring(0, 2) == "$ ") {
        $(o).html('<span style="user-select: none; -webkit-user-select: none; -moz-user-select: none; -ms-user-select: none;">$ </span>' + str.substring(2));
    }
});

@stevenjoezhang there is not only in Hexo need to be added. Some CSS need to add too. For now no need to think about this feature, I'll think about this later.

@xu-song @ivan-nginx Use shell instead of bash, sh or zsh

@maple3142 Thanks. Your comment there in https://github.com/theme-next/hexo-theme-next/issues/448#issuecomment-431677117 helped me a lot, even though I have no clue what the hexo-theme-next is all about. :joy: :+1:
