Singleton block construct with attributes?

Singleton block construct with attributes?

[Axel Rauschmayer]

[-- Attachment #1.1: Type: text/plain, Size: 771 bytes --]

For two filters of mine, I’d like to use a singleton block construct that 
triggers them via a class. I was considering using a horizontal rule:

---{.pause}

Alas, that doesn’t work. What is a good alternative? If there isn’t any, I 
can use the following syntax, but I’d prefer something that fits into a 
single line.

::: pause
:::

I thought "Aha! But what about
https://pandoc.org/MANUAL.html#extension-attributes?". However:

% echo '---{.pause}' | pandoc --from=markdown+attributes
The extension attributes is not supported for markdown

https://pandoc.org/MANUAL.html#non-default-extensions seems to imply that
these (including 'attributes') are all markdown extensions. What am I
missing?

[Gwern Branwen]

If you simply want some sort of keyword to plop in, why the obsession
with attributes? There are lots of things you could write. The thing
I'd immediately think of is writing a little div or span with a class,
like:

     $ echo '[]{.pause}' | pandoc --from=markdown+native_spans --write native
    [Para [Span ("",["pause"],[]) []]]

Now you just match on `foo (Span (_, ["pause"], _) _) = rewriteCode
...` in your API use.

`attributes` is only supported for commonmark + variants,
including gfm and commonmark_x.

When I need a marker like this I use a code span, like

    `--pause`

``````lua
-- Look for a paragraph
function Para (para)
  -- With only one child
  if 1 == #para.content then
    local child = para.content[1]
    -- Which is a code span
    if 'Code' == child.type then
      -- Ignore it if it has a class .code, i.e. `--pause` is a marker, but
      -- `--pause`{.code} is "actual" code.
      if child.classes:includes('code') then
        return nil
      end
      -- If it is the marker return some block content
      if '--pauae' == child.text then
        return whatever()
      end
    end
  end
  return nil
end
``````

Oops. Typo on the last if line!

Thanks for all the suggestions!

With the right settings, some horizontal rule syntaxes do indeed work:

% echo '___{.pause}' | pandoc --from=commonmark+attributes
<p><span class="pause">___</span></p>
% echo '***{.pause}' | pandoc --from=commonmark+attributes
<p><span class="pause">***</span></p>
% echo '---{.pause}' | pandoc --from=commonmark+attributes
<p>--<span class="pause">-</span></p>

Ahem, I thought wrong: Pandoc actually treats horizontal rules as text if 
there are attributes in the same line.

Re: Singleton block construct with attributes?

[John MacFarlane]

Attributes on block-level items
have to go on the line before.

{.pause}
* * * *
