Hi, I'm trying to resolve citations inside attributes, i.e. something like<div><br></div><div>```{.c caption="nice piece, cf. [@FOO]"}</div><div>int main() {</div><div>&nbsp; &nbsp; return 42;</div><div>}</div><div>```</div><div><br></div><div>Since Pandoc/Citeproc currently do not handle citations of this kind, I'm trying to resolve this manually with a Lua filter: Put this piece into a new temporary document, run Pandoc+Citeproc on this document using `pandoc.utils.run_json_filter`, retrieve the processed string and put back it in the original place, i.e. the caption.</div><div><br></div><div>However, this approach seems to be not working?</div><div><br></div><div>As a MWE I've tried this document `test.md`:</div><div><br></div><div>```markdown</div><div><div><div>---</div><div>references:</div><div>- author:</div><div>  - family: Wuppie</div><div>  id: FOO</div><div>  title: Lorem Ipsum</div><div>---</div><div>see [<span style="text-decoration: underline;">@FOO</span>]</div>```</div><div><br></div><div>Running `pandoc -t json --citeproc test.md` the result is&nbsp;</div><div>```json</div><div>{"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":"”"}]]}]}]]}]]}]}</div><div>```</div><div>, i.e. the citation is properly resolved (as expected).</div><div><br></div><div>However, using the Lua filter `codecite.lua` (for the sake of simplicity, I'll just replace the old block directly with a citation):</div><div><br></div><div>```lua</div><div><div><div>local meta</div><br><div>function render_blocks(b)</div><div>    &nbsp; &nbsp; local blocks = {pandoc.Para{pandoc.Str("see [@FOO]")}}</div><br><div>    &nbsp; &nbsp; local tmp = pandoc.utils.run_json_filter(</div><div>&nbsp; &nbsp; &nbsp; &nbsp; pandoc.Pandoc(blocks, meta),</div><div>        &nbsp; &nbsp; &nbsp; &nbsp; 'pandoc',</div><div>&nbsp; &nbsp; &nbsp; &nbsp; {'--from=json', '--to=json', '--citeproc'}</div><div>&nbsp; &nbsp; )</div><div>    &nbsp; &nbsp; return tmp.blocks</div><div>end</div><br><div>return {</div><div>&nbsp; &nbsp; { Meta = function (m) meta = m end },</div><div>&nbsp; &nbsp; { Block = render_blocks }</div><div>}</div></div></div><div>```</div><br></div><div>and running `pandoc -L codecite.lua test.md -t json` the result is just&nbsp;</div><div><br></div><div>```json</div><div>{"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]"}]}]}</div><div>```</div><div>, which is unexpected (citation is not resolved).</div><div><br></div><div>Clearly I'm missing something here. But what is it? Can you please advise?</div><div><br></div><div>`pandoc --version`:&nbsp;pandoc 2.14.2</div><div><br></div><div>Thanks!&nbsp;</div><div>Carsten</div><div><br></div>
