Insert a page number of a reference

[yakatz]

I need to write something like:

This issue is addressed later. See the reference to this topic on [page @page:my_reference].

At that other point, I have this content:

blah blah [@thisCitation]{#page:my_reference}

I get a warning from citeproc that the citation is not found (obviously because it is not a section that can be cited).
The generated LaTeX output does include a label for this phantomsection:

blah blah
\phantomsection\label{page:my_reference}{{[}\citeproc{ref-thisCitation}{12}{]}},

but the referencing location looks like this:

See the reference to this topic on {[}page
\citeproc{ref-page:my_reference}{\textbf{page:my_reference?}}{]}

Is there any way for me to get the page number of this fake section?

Version:
pandoc.exe 3.2
Features: +server +lua
Scripting engine: Lua 5.4

My execution: pandoc --lua-filter=tools/include-files.lua --lua-filter=tools/alignment.lua --filter=mermaid-filter.cmd --filter=pandoc-crossref --citeproc --lua-filter=tools/short-captions.lua --standalone --pdf-engine=xelatex -N --template=template-umd-dissertation.tex --highlight-style=haddock -o paper.tex paper.md

Pandoc does not have a mechanism to refer by page (it would not make sense for all formats). I wrote a filter that covers this use case, using a different syntax than yours. You can find it here.

Thank you. The link in your README to your crossrefenum implementation is broken, but I assume this is your implementation: https://bastien-dumont.onmypc.net/git/bdumont/crossrefenum

[yakatz]

I actually had to modify it because my \labels were being created twice, so I just commented out the section of the lua script that does that. I think I have everything working now.

Oh, thank you for reporting that, this comes from a rather recent change in the LaTeX writer I had not come across before! The crossrefenum package is available on the CTAN and included in TeXLive since 2023: adding \usepackage{crossrefenum} in your template should be enough.
