Thanks for reporting!

Unfortunately we cannot release newest pandoc until skylighting is 
releasable on all architectures. That issue is sort-of tracked at 
https://bugs.debian.org/869356

I looked at the code changes, but they are too complex for me to 
backport, so this cannot be addressed properly until skylighting is 
working.

Bug#870248: pandoc: Collision for lang-Variable when using specific language for pandoc-citeproc and Babel (Latex)

[cms]

Package: pandoc
Version: 1.19.2.1~dfsg+really1.19.1-1
Severity: normal

Dear Maintainer,

it seems that both Babel and pandoc-citeproc use `lang` as a variable to set 
the language, but they don't use the same language codes, e.g. for german: 
ngerman (Babel) and de-DE (pandoc-citeproc), so when using Babel and 
pandoc-citeproc, setting another language throws an error either from Babel or 
from pandoc-citeproc. This issue has been reportedly solved in the most recent 
versions of pandoc -- see https://github.com/jgm/pandoc-citeproc/issues/297 )

What I'm trying to do: Generate a PDF from Markdown using two separate files 
(markdown + yaml)

pandoc -o test.pdf --csl my.csl --bibliography mybib.bib test.md test.yaml

The lang is defined in test.yaml. If I set lang: ngerman, pandoc-citeproc 
throws an error because it is looking for locales-ng.xml, which doesn't exist.
If I set lang: de-DE, Babel throws an error because it doesn't know that 
language.


There is a workaround:

It seems, that pandoc-citeproc takes the first two letters of the lang variable 
and then looks for a file named locales-xx.xml, where xx are the first two 
letters of the lang variable, e.g. when defining lang: ngerman, pandoc-citeproc 
looks for locales-ng.xml.
Making a symbolic link from locales-ng.xml to locales-de-DE.xml did the trick. 
I haven't tried other languages, though.

Best,
Claus-Michael
