Greetings,

Now (based on the BlockCode example from my LUA code is simply reduced to :

I based that on examples I found here : https://issueexplorer.com/issue/lierdakil/pandoc-crossref/319

and based on the Span description from https://pandoc.org/lua-filters.html

My very obvious expectation is that any generated span element has a "ggg" identifier.

I don't know how I could define a more trivial function. However, nothing ever works.

This started with comparisons and real code. Since nothing works, I have reduced it to this oneliner, which still doesn't.

When I compile my (.tex) code (into epub), this continues producing  blocks such as :

My compilation is run with this command :

pandoc -L ../pandocLabelFilter.lua -Fpandoc-crossref -o ebook.epub epub.tex --epub-metadata=metadata.xml --epub-cover-image=IMG/couverture.jpg --toc --toc-depth=2 --resource-path=IMG/ --default-image-extension=jpg

../pandocLabelFilter.lua contains what I pasted above.

So, what must I do additionnally so that any LUA code accepts to be run for real ?

Thanks,

Vincent
