How to resolve citations inside attributes

How to resolve citations inside attributes

[Carsten Gips]

[-- Attachment #1.1: Type: text/plain, Size: 682 bytes --]

Dear all,

I'm trying to resolve citations inside attributes, i.e. 

```{.c caption="nice, see [@KEY]"}
...
```

Pandoc and Citeproc are currently not handling citations inside am 
attribute like in the example. How can I resolve these citations anyway?

Thanks,
Carsten

I've tried to resolve this manually by extracting this piece with a Lua 
filter, converting it into a new document and running Pandoc plus Citeproc 
on this temporary document with `pandoc.utils.run_json_filter`, retrieving 
the processed citation and putting it back as codeblock caption in the 
original document. However, this approach seems not to be working.

To narrow this down further, I wrote a short document (`test.md`, see 
attachment) and a Lua filter (`codecite.lua`, see attachment). (To make it 
even shorter, in the Lua filter I simply replace the text block of the 
document with a similar new block).

But this does not seem to work. The call `pandoc -L codecite.lua test.md -t 
json` returns only 

```json
{"pandoc-api-version":[1,22],"meta":{"references":{"t":"MetaList","c":[{"t":"MetaMap","c":{"author":{"t":"MetaList","c":[{"t":"MetaMap","c":{"family":{"t":"MetaInlines","c":[{"t":"Str","c":"Wuppie"}]}}}]},"id":{"t":"MetaInlines","c":[{"t":"Str","c":"FOO"}]},"title":{"t":"MetaInlines","c":[{"t":"Str","c":"Lorem"},{"t":"Space"},{"t":"Str","c":"Ipsum"}]}}}]}},"blocks":[{"t":"Para","c":[{"t":"Str","c":"see 
[@FOO]"}]}]}
```
i.e. the citation is not resolved.

However, if I run Pandoc directly on this document, i.e `pandoc -t json 
--citeproc test.md`, the result is as expected:

```json
{"pandoc-api-version":[1,22],"meta":{"references":{"t":"MetaList","c":[{"t":"MetaMap","c":{"author":{"t":"MetaList","c":[{"t":"MetaMap","c":{"family":{"t":"MetaInlines","c":[{"t":"Str","c":"Wuppie"}]}}}]},"id":{"t":"MetaInlines","c":[{"t":"Str","c":"FOO"}]},"title":{"t":"MetaInlines","c":[{"t":"Str","c":"Lorem"},{"t":"Space"},{"t":"Str","c":"Ipsum"}]}}}]}},"blocks":[{"t":"Para","c":[{"t":"Str","c":"see"},{"t":"Space"},{"t":"Cite","c":[[{"citationId":"FOO","citationPrefix":[],"citationSuffix":[],"citationMode":{"t":"NormalCitation"},"citationNoteNum":1,"citationHash":0}],[{"t":"Str","c":"(Wuppie,"},{"t":"Space"},{"t":"Str","c":"n.d.)"}]]}]},{"t":"Div","c":[["refs",["references","csl-bib-body","hanging-indent"],[]],[{"t":"Div","c":[["ref-FOO",["csl-entry"],[]],[{"t":"Para","c":[{"t":"Str","c":"Wuppie."},{"t":"Space"},{"t":"Str","c":"n.d."},{"t":"Space"},{"t":"Span","c":[["",[],[]],[{"t":"Str","c":"“"},{"t":"Str","c":"Lorem"},{"t":"Space"},{"t":"Str","c":"Ipsum"},{"t":"Str","c":"."},{"t":"Str","c":"”"}]]}]}]]}]]}]}
```

Clearly I'm missing something here. But what is it? Can you please advise?


PS: `pandoc --version`: pandoc 2.14.2

Citations are only recognized when they're parsed as markdown.
@key in a code block or attribute won't be parsed.

You could use the pandoc Lua 'read' function to parse the
contents of your attribute as Markdown and then do something with that.

Thanks, 'read' was the hint I was looking for! It's working now :)
