I’m assuming that because the discussion has shifted from ‘what should the markdown look-like to users’ to ‘how many div tags should we use and by the way what exactly is a div tag anyways’ that this issue has been sort’ve accepted. But the last post on this issue is from last year and I’m not sure where it would move forward. Any news?
No proposal has been accepted.
The use case I’ve got is, on github, my team now reads and votes on issues before sprint kickoff. Right now those votes are just plaintext as comments, so if you’re voting as a junior dev and a senior dev has already voted you cant help but be biased by glancing at the comments. I’d like to put the votes in spoiler tags so that a reader has to have an explicit intent to see the vote. I noticed that stackoverflow was already doing this with a scheme that was perfect for my use case, but github was not.
I’m a bit unclear about what you’re looking for. If you’re trying to do this on github, then only changes to github’s Markdown processor will help you, and this isn’t the right place to be asking.
If you’re asking how one might achieve this with a setup that used a CommonMark parser, then it seems to me that you could achieve what you want without any syntax changes at all, by establishing conventions.
For example, you could establish the convention that any block quote beginning with a single ! will be treated as a spoiler. On the server, you’d then walk the AST after parsing, looking for blockquotes that fit this description, and inserting some raw HTML around them to make them display hidden by default, with a button to display them.
No fancy block attribute syntax is needed for this, and there are some advantages to NOT using a fancy block attribute syntax (your document will degrade nicely on github or another Markdown renderer). Note also that, even if there were a fancy block attribute syntax, you’d still have to do some custom processing of the AST. Although we might consider generic block attribute syntax, “spoiler” seems far too specialized a thing to be part of the spec.
