[NTG-context] Combine lua and btx setup, was: Re: Customize citation format of a bibliography (use the short form as reference format)

23 Apr 2024

      Here is a solution for the first part of my question. This is based on
https://www.mail-archive.com/ntg-context@ntg.nl/msg101156.html
and try and error based on publ-imp-aps.mkvi and publ-imp-apa.mkvi:

It display now the citation _and_ numbering labels in the short form:
```
\setupinteraction[state=start]

\startbuffer[testdata]
@Book{knuth1,
	author = {Donald E. Knuth},
	title = {TEX and METAFONT. New directions in typesetting},
	year = {1979},
	publisher = {Addison-Wesley},
}
@Article{someother,
	author = {Some Person and Some Otherperson},
	title = {Another title},
	year = {1900},
}
\stopbuffer

% enable tracing
\enabletrackers[publications, publications.crossref, publications.details, publications.cite, publications.strings]

\usebtxdataset[main][testdata.buffer]
\usebtxdefinitions[aps]
\setupbtx[dataset=main]
\definebtxrendering[bibrendering][aps][dataset=main, numbering=short]
\setupbtxlist[aps][
  alternative=b,
  distance=.5em,
]
\setupbtx[aps:cite][alternative=short]

\starttext

Knuth developed \TeX \cite[knuth1]
Several persons said something \cite[someother].

\placelistofpublications[bibrendering]

\stoptext
```

The remaining part now is to mark publications of Knuth in a different way.
I have tried this and failed. Here is my code so far:
```
\startluacode
function render_cite(short, author)
	print(author)
	if author:lower():find("knuth") then
		context("[>" .. short .. "]")
	else
		context("[" .. short .. "]")
	end
end
\stopluacode
\definebtx[aps:cite:special][aps:cite]
\startsetups btx:aps:cite:special
	\btxcitereference
	\ctxlua{render_cite([==[\btxflush{year}]==], [==[\btxflush{author}]==])}
\stopsetups
% use it with \cite[special][knuth1]
```
This has several problems:
- \btxflush{short} does not work as I expected that. How can I get the short form?
- \btxflush to pass arguments to lua does not work as intended. On the lua side the
   variable "author" resolves to "\btxflushauthor{author}" and not to "D. E. Knuth".
   How can I pass the data?

I use Lua only because I find it more convenient as a programming language. If a
plain tex solution is simpler, I'm happy to use that. 

Another question that came up while studying the source code:
What effect have \c!, \s!, and \v!? These commands exist a lot in the above
cited files.

Hi,
...
The APS style is an example of a number-based citation system. As you
are looking for a tag-based citation, it might be better to start with
something like the APA style.
I'm kind of satisfied with the publication-list layout of the APS style so I chose
this as a base. If it is simpler to start with the APA style, I can do that.
My hope is that it is possible to just change the "label" that is used for
referencing and keep everything else as is.
...
Is there some specification for your short tag-based citation style?
biblatex implements this with the "alphabetic" style. I'm not aware of
a specification, though. Does the "short" form in ConTeXt exist for a
specific reason? :)

Hi,
I'm trying to customize a cite format in a bibliography. Currently,
I'm using the aps style which fits so far, except of the plain number
as reference. In concrete, I want to change the following:
- Use the first letter of the last name and the year as reference
(this should be exactly the short form). It is more less also
described here [1].
- Highlight publications of a certain author with an extra char (e.g.
'>')
Here is a minimal example (lets assume, every occurrence of Knuth
should be highlighted): ```
\setupinteraction[state=start]
\startbuffer[testdata]
@Book{knuth1,
  author = {Donald E. Knuth},
  title = {TEX and METAFONT. New directions in typesetting},
  year = {1979},
  publisher = {Addison-Wesley},
}
@Article{someother,
  author = {Some Person and Some Otherperson},
  title = {Another title},
  year = {1900},
}
\stopbuffer
% enable tracing
\enabletrackers[publications, publications.crossref,
publications.details, publications.cite, publications.strings]
\usebtxdataset[main][testdata.buffer]
\usebtxdefinitions[aps]
\setupbtx[dataset=main]
\definebtxrendering[bibrendering][aps][dataset=main]
% this seems to have no effect?
\setupbtx[alternative=short]
\starttext
Knuth developed \TeX \cite[knuth1].
Several persons said something \cite[someother].
\placelistofpublications[bibrendering]
\stoptext
```
It should be rendered as:
```
Knuth developed TeX [>Knu79].
Several persons said something [PO00].
[Knu79]	D.E. Knuth, TEX and METAFONT. New directions in
typesetting (Addison-Wesley, 1979). [PO00]	S. Person and S.
Otherperson, Another title, (1900). ```
How can I achieve that \cite[something] always renders in the short
form by default? How can I customize that references to Knuth contain
this extra '>'? How can I customize the APS style to also use the
short form in the list of publications instead of numbers?
Best
