Add chapter numbering to theorem numbering

[cpraveen]

Hello, I get numbering for prf:theorem, prf:proof, prf:example, etc. but these do not have the chapter number appended to them.

Is it possible get theorem, etc numbering like

CHAPTER_NO.THEOREM_NO

@fwkoch could you chime in here to elucidate on how to achieve this?

Thanks for the ping @agoose77

Hey @cpraveen - there currently is not yet a way to do this without hardcoding the chapter numbers. To hardcode a chapter number for a page, in the page frontmatter you can do:

---
numbering:
  enumerator: 5.%s
---

where 5 is the hardcoded chapter number. You can also set this for only prf:theorem with:

---
numbering:
  proof:theorem:
    enumerator: 5.%s
---

You can also set the explicit enumerator on a single proof with:

:::{prf:theorem}
:enumerator: 5.3

...

I suspect you want to do this without hardcoding the chapter numbers, though. That's captured in this issue: #1787 - once that's done, you would be able to do something like enumerator: {chapter}.%s...
