Functions with dashes in name not showing up in right sidebar

[lognaturel]

I'm documenting functions with dashes in their names:

.. function:: count-non-empty(nodeset)

  Returns the number of non-empty members of ``nodeset``.

You can see on the rendered site that count-non-empty is not in the right sidebar and does not have an anchor associated with it.

I posted on Stackoverflow and was told this could be a theme issue.

It occurred to me that I could quickly try a different theme. I've confirmed it's an issue there too.

If no language domain is selected, Sphinx uses Python by default. (https://www.sphinx-doc.org/en/master/usage/domains/index.html)

Python does not allow - in identifiers, including function names, so it could be tripping on that. I see an old config file for Sphinx that specifies the js domain instead with a comment about syntactic compatibility, but that's as far as I've been able to dig.

Thanks so much for those tips!

Much gratitude to you @dgw, that's exactly what that config was for and unfortunately it was omitted when migrating to Furo.

I'd love to give you some internet points if you're on Stackoverflow!

Awesome that my advice helped you solve the problem! I summarized this on the Stack Overflow question you linked in the OP, so it won't look so lonely :)
