Expose code fence attributes to SyntaxHighlighterAdapter::write_highlighted

[hongquan]

I'm building my personal blog, which let admin to write content in Markdown. The blog is about programming so highliting code block is important. But because the Comrak + Syntect combo is not strong enough, I want to create a flexible SyntaxHighlighterAdapter which can highlight code block with Syntect, or defer to client side, where I use Shiki. To let this adapter know which side (server or client) to do the job, will add some extra attribute to code fence, like if it encounters:

  ````rust {lines: true}
  const a: u8 = 1;
  ````\

It will let client side to do. But to do that, I need SyntaxHighlighterAdapter::write_highlighted to be passed the attributes: HashMap<String, String> like write_code_tag and write_pre_tag.

Could the API be changed?

@hongquan I probably misunderstand what you're trying to do. But if you're using your own syntax highlighter, then you don't need to use the Syntect component at all. That is what we do - we use a Ruby syntax highlighter and enable the --full-info-string option in order for the full info string (which would contain the {lines: true} from your example) to be passed through.

@digitalmoksha I want both, as in previous comment:

Most of the cases, I want to highlight at backend side, only some cases I defer to client side (JS).
