Subject: Re: Lua Filter for citeauthor and citetitle in HTML

Albert,<= /span>

that is vexingly sh= ort, but the syntax is perfectly clear. Thank you! Since I toiled at this f= or a while, your filter will provide me with some interesting learning oppo= rtunities. I will play around with it and see how it behaves with the other Lua filters.

Thanks again,<= /o:p>

Newer pandoc versions allow to shorten this to

```
function Pandoc (doc)
doc.meta.references =3D pandoc.utils.references(doc)
doc.meta.bibliography =3D nil
return doc
end
```

Here's a "quick n' dirty" filter that should make your `[@key]{.t= itle}`
syntax work:

```
function Pandoc (doc)
doc.meta.references =3D pandoc.utils.references(doc)
doc.meta.bibliography =3D nil
return doc:walk{
Span =3D function (span)
-- check that the span contains only a single cite object
local cite =3D span.content[1]
local citations =3D cite and cite.citations or nil
if #span.content =3D=3D 1 and cite.t =3D=3D 'Cite' and #citations =3D=3D 1 = then
local cite_id =3D citations[1].id
local ref =3D doc.meta.references:find_if(
function (r) return cite_id =3D=3D r.id end
)
if ref and span.classes[1] then
-- replace the span with a specific citation field
return ref[span.classes[1]]
end
end
end
}
end
```

It's a bit condensed and not well documented, so let me know if you have questions.
