pandoc xnos filter fails in ubuntu 24.04

[alainmuls]

L&G,

I switched to Ubuntu 24.04 from 22.04. I have a setup on 22.04 where I use the pandoc filters for figures and tables (pandoc-filternos, pandox-eqnos) which works fine on 22.04. I also replaced these filters with the pandoc-xnos filter, still working correctly on 22.04. The pandoc version is pandoc 2.9.2.1

Using the same setup on 24.04 gives following error with pandoc 3.2 (Features: +server +lua) :

RuntimeError: Cannot understand pandocversion=3.2
Error running filter ./bin/pandoc-xnos:

I installed "apt-file list python3-pandocfilters" hoping this would resolve the issue, but with no result.

Any help much appreciated

You should ask the maintainer of the filter...

It seems pandoc-xnos only supports pandoc version 1.x and 2.x (see pandocxnos/core.py line 174)

pattern = re.compile(r'^[1-2]\.[0-9]+(?:\.[0-9]+)?(?:\.[0-9]+)?$')

There seems to be no activity on pandoc-xnos. It's not just the version regex that's broken, but the ability to use figure references.

Is there an alternative to generating numbered figures in Pandoc 3.x?

[jgm]

does pandoc-crossref do this?

[elahav]

I'll check. For now I downgraded to the latest 2.x release.

Querverweis, but it's not what I would describe as "production ready". (I do use it in production for a project, but docs and features are lacking a bit.)

Just change

pattern = re.compile(r'^[1-2]\.[0-9]+(?:\.[0-9]+)?(?:\.[0-9]+)?$')

to :

pattern = re.compile(r'^[1-3]\.[0-9]+(?:\.[0-9]+)?(?:\.[0-9]+)?$')

[tarleb]

It probably won't work correctly for figures though.

[elahav]

It doesn't work. Something has changed in the way pandoc represents figures and pandoc-xnos has not been updated.
