Footnote backrefs

[bjhess]

In Buttondown I see a footnote resolved with a backref link. See here:

In my usage the footnote doesn't render with a backref. I end up with something like:

<li id="fn:1" data-id="0e1717e6-e02b-4303-b9cd-222f722be1f8">
  <p>Footnotes</p>
</li>

Without the backref link that I see on Buttondown:

<a class="footnote-backref" href="#fnref:1">↩</a>

I don't find any instances of backref in the repo, so I'm wondering if you're extending the extension in Buttondown to achieve this?

OSS-6 Footnote backrefs

Yup; that's being added what we're actually using on the backend to render the final HTML spat out by Tiptap (since we need to be able to render tiptap and 'plain' Markdown to the same final artifact), which is the python-markdown extension.

In terms of extending the extension to achieve this — I am not sure we want to be so heavily prescriptive as to default to adding the backref, but I think we could absolutely expose a hook to allow overriding the render (which would also solve #11).

That makes sense, @jmduke. Thanks for sharing what y'all are doing. Just added render-time backref processing to Pika. Thanks!

(I'm assuming this issue can be closed, but I'll leave that up to you!)
