org-cite: make 'suppress-author' a citation 'style'

org-cite: make 'suppress-author' a citation 'style'

[Bruce D'Arcus]

Hi Nicolas,

As I was working on adding a function to generate the new cite syntax,
an idea occurred to me that I'd like to raise, that would simplify
this model and syntax.

I ran the idea by the pandoc list just to confirm my thinking was
reasonable, since that has a lot of experience using these plain-text
citations.

https://groups.google.com/g/pandoc-discuss/c/zbntclaBWDc/m/DCx-mpfcDQAJ

Let's review:

In org-cite, we have citations, and citation items.

Citations may have optional styles.

Citation items may have an optional "suppress-author" "variant",
indicated with a "-". So:

[cite:-doe19;doe20]

The idea:

This distinction is wrong, and we should treat "suppress-author" as a
citation style instead.

The result would be:

[cite/supress-author:doe19;doe20]

Or even can keep the shorthand:

[cite/-:doe19;doe20]

In fact, with the change, could even remove it entirely

If you read the discussion in the pandoc list, there is mild, but I
don't think convincing, pushback.

Part of that pushback is an artifact of the fact that pandoc citations
don't have a notion of citation style, where you specify things like

OTOH, pandoc and (haskell) citeproc author John MacFarlane agrees that
in retrospect the pandoc decision was probably wrong, in part because
of another related issue.

Supress-author is a convention that CSL implementations settled on,
arguably a hack, to get around lack of explicit support for natbib
citet-like citations (though this is being added in the next version).

So to get "Doe (2019) argues" you would need to write "Doe [@doe19]"
in pandoc, for example.

But if you can do this in org-cite, "suppress-author" is no longer needed:

"[cite/text:@doe19] argues ..."

Both should probably be possible, but the textual (aka narrative)
style is what most users are looking for there IMO.

I think a positive side-effect is this model would match better LaTeX
output models (natbib and biblatex namely).

WDYT?

Correction, though it doesn't change the conclusion.

Incorrect: the pandoc syntax for citet-like rendering is:

@doe19

So to drop the brackets.

We introduced :suppress-author because someone requested it at some
point. I don't remember who, but it may be worth asking that person.

I think there are two points to consider before removing suppress-author
syntax:

1. does it make sense to apply it independently on references within
   a full citation?

2. does it make sense to apply it on top of another style?

If both answers are no, this can definitely go away.

Note that Org Citation library does not recognize styles. It is up to
the processor to interpret it as a short-hand for "suppress-author".

I did some quick searching.

Wow; this goes back a long time!

Anyway, Richard Lawrence summarized previous discussions, which includes
this detail, in this 2015 post:

https://lists.gnu.org/archive/html/emacs-orgmode/2015-02/msg00932.html

Not sure if he introduced the idea or not, but if not, he should know.

Yes; excellent summary.

As I say, my impulse is to say no to both, outside some corner cases that
people could work around in other ways.

But I hope people will challenge me if this is a bad idea.

And hopefully Richard can weigh in.

If both answers are no, this can definitely go away.

I also came across this post from 2018 from Andras ...

https://orgmode.org/list/87in8jaywk.fsf@all.hu/

... which includes a link to his proposal on what we now call styles,
but there he calls (a la the TeX world) commands:

https://github.com/andras-simonyi/citeproc-el/wiki/Citation-types-and-commands

There, he includes "suppress author" as one among those.

In both links, he considers stacking a style with suppress-author, for
example "bare" and "bare + s.a". 

So that would be an argument for keeping suppress-author.

Maybe I'm missing something, but can those not be represented with flat styles?

E.g. "bare + s.a." is simply something like "date"?

> So that would be an argument for keeping suppress-author.

The question I raised is less whether that's needed, and more whether
it's a property of the citation, or the individual items within the
citation.

Dear All,

my 2c on this issue: citeproc-el supports per cite author suppression
under the hood, but citeproc-org always maps "suppress author" mode
citations to suppressing only the first cite, because my impression
was also that this is a citation-level option. This is how the
proposal on the citeproc-el wiki treats it too (which was, BTW, joint
work with Denis Maier).

How would you deal with these?

#+begin_example
[cite/-:@doe20; @doe21]
[cite/-:@doe20; see also @smith19]
[cite/text:@doe20; see also @smith19]
#+end_example

My thought is you want to treat the author of the first listed cite as
suppressed, or placed in-text in the last case, but that you wouldn't
touch the other author?

yes, exactly -- since it's difficult to see (at least for me) how the
context could supply the author information for the subsequent cites.

So the output for the first one would be:

(2020, 2021)

..., and not:

(2020, Doe 2021)

As in, you would suppress the author not on the first cite (what you
wrote in the original reply), but the author of the first cite?

To me, that's the only wrinkle of having this a citation-level style;
that a processor would need to be smart enough to handle cases like
that, for output styles that require it.

But otherwise it's easier and more efficient for the user.

Re: org-cite: make 'suppress-author' a citation 'style'

[Denis Maier]

Hi,

just some general remarks on that issue: I tend to think that treating 
"suppress-author" as a mode/style/command would indeed be appropriate. 
As the minus shorthand is inherited from pandoc, it might be worth 
pointing out that pandoc's syntax owes quite a lot to the markdown 
philosophy, which is also emphasized by pandoc:

 > Markdown is intended to be as easy-to-read and easy-to-write as is 
feasible.
 >
 > Readability, however, is emphasized above all else
(https://daringfireball.net/projects/markdown/syntax#philosophy)

That is, markdown tries to use a syntax as concise as possible, without 
verbose commands and such. See e.g. this discussion: 
https://groups.google.com/g/pandoc-discuss/c/ydG9CI_XEEU/m/3LHxvp23BAAJ

The price for this is a certain opaqueness, and, to a certain degree, a 
loss of precision, expressiveness and extensibility.

Anyway, back to the modes question:

#+begin_example
[@doe]

[-@doe]

@doe

@doe [34]

-@doe [34]
#+end_example

gives us in pandos AST:

#+begin_pandoc_ast
[Para [Cite [Citation {citationId = "doe", citationPrefix = [], 
citationSuffix = [], citationMode = NormalCitation, citationNoteNum = 1, 
citationHash = 0}] [Str "[@doe]"]]
,Para [Cite [Citation {citationId = "doe", citationPrefix = [], 
citationSuffix = [], citationMode = SuppressAuthor, citationNoteNum = 2, 
citationHash = 0}] [Str "[-@doe]"]]
,Para [Cite [Citation {citationId = "doe", citationPrefix = [], 
citationSuffix = [], citationMode = AuthorInText, citationNoteNum = 3, 
citationHash = 0}] [Str "@doe"]]
,Para [Cite [Citation {citationId = "doe", citationPrefix = [], 
citationSuffix = [Str "34"], citationMode = AuthorInText, 
citationNoteNum = 4, citationHash = 0}] [Str "@doe",Space,Str "[34]"]]
,Para [Cite [Citation {citationId = "doe", citationPrefix = [], 
citationSuffix = [Str "34"], citationMode = SuppressAuthor, 
citationNoteNum = 5, citationHash = 0}] [Str "@doe",Space,Str "[34]"]]]
#+end_pandoc_ast

So, suppress author is essentially a mode here.

FWIW, it might also be interesting to look at biblatex:
biblatex has a textcite command:
\textcite{doe2021} => Doe (2021)

Now, if you want to cite multiple entries, each with prefix and suffix, 
you'll need a special variant \textcites!
\textcites[12]{foo}[34]{bar} argue ...
=> Foo (2021, p. 12) and Bar (2021, p. 34) argue ...

I'm not sure how that fits into the org context. Interestingly, I 
couldn't find an easy way to get "Doe (2021, p.34; see also Smith 2020) 
... argues". You'd probably have to resort to lower level commands such 
as \citeauthor in combination with other commands.
\citeauthor{doe} \parencites*[34]{doe}{smith}

Addendum:

[@doe; -@foo]

gives us:

[Para [Cite [Citation {citationId = "doe", citationPrefix = [], 
citationSuffix = [], citationMode = NormalCitation, citationNoteNum = 1, 
citationHash = 0},Citation {citationId = "foo", citationPrefix = [], 
citationSuffix = [], citationMode = SuppressAuthor, citationNoteNum = 1, 
citationHash = 0}] [Str "[@doe;",Space,Str "-@foo]"]]

So, each citation in that cite has an individual mode, which goes in the 
direction indicated by Richard Lawrence in his earlier message. Maybe 
that speaks for two levels of styles, one pertaining to the whole 
citation group, one to the individual citations. Does that make sense?

Actually, that won't print the author name of =smith=. AFAIK If you want to
suppress the author in the first citation but not in the second, you need to be
even more low-level:

\citeauthor{Chomsky1995} (\cite*[34]{Chomsky1995}, \cite{Kayne1994})

At least that's the only way I've been able to find.

IOW it seems that in biblatex, suppress-author (obtained by the asterisk
following the command) is a property of the citation command, even if it
includes multiple citations. OTOH there are real cases (I have written
references such as the example here myself) where you want it to be a property
of the individual citation.

The thing about biblatex is that it offers low-level commands that allow you to
create unusual citations (my default LaTeX header contains three definitions of
citation commands that biblatex doesn't provide but which I use quite a lot). So
I would argue that it's better to keep the syntax =-@key=, just to keep the
system flexible in case the need arises.

It would help at this point if you could show an example, as I can't
think of one that can't be addressed.

As I replied to Richard, a citation with references to different
authors can already be addressed.

Adding complexity for hypotheticals has costs though.

We should be able to identify a concrete case here that won't work
with the change I suggest, but that we agree should be supported.

I don't remember exactly anymore, and a quick search does not turn up
the source, but I can say in general that the concern back then was to
make the citation syntax at least as flexible as the BibLaTeX citation
commands, to support users who currently use BibLaTeX (and don't have
much interest in non-LaTeX output).

I don't remember what my thinking was exactly, but it was probably
something like this: (a) we need citations with multiple references; (b)
in some such citations we may need to suppress the author of some
references without suppressing the author of others; (c) thus
:suppress-author must be a reference-level property, not a property of
the whole citation object and (d) uniformity demands that every
reference should have it (even if it doesn't make sense in practice to
apply it to references in the middle of the list).

That said, here is a possible use case for this: suppose you are
referencing multiple works from a given author and want to avoid
printing the author's name multiple times, but also want to include a
further reference to a work by another author:

e.g. you can write

Smith claims foo [(cite): -@Smith2019; -@Smith2020; see also @Jones2018].

to render

Smith claims foo (2019; 2020; see also Jones 2018).

Does that help?

Yes; thank you!

You identified the same case Andras and I discussed just above.

I think the solution is simple; with the updated syntax:

[cite/-:@Smith2019;@Smith2020; see also @Jones2018].

So the rule is (and this is for the processor to worry about, of
course, not org), when a suppress-author style is specified, the
suppression only applies to the author of the first citation
item/reference. That would generate the output you noted.

A processor like citeproc.el already knows how to group and sort by
author, so it could also be smart enough to handle that, without
requiring the user to individually mark some for suppression.

I worry we're making the general and simple case needlessly
complicated with the current model and syntax for this.

I think I see what you mean after parsing this a few times, but I would
rephrase the rule, since the way you phrased it initially seemed to
contradict the example. The point of my example was that author
suppression should also apply to the author of the *second* reference in
the list, though that happens to be the same author as the author of the
first item. So maybe the rule is more like: "when a suppress-author
style is specified, the suppression only applies to the initial segment
of citation items/references that have the same author as the first
reference"?

I think Bruce's point was that author suppresion list items other than 
the first lies in the jurisdiction of the citeproc, and has to be 
handled depending on citation style. (I.e., user input does /not/ matter 
here.)

[cite/-:@Smith2019;@Smith2020; see also @Jones2018].

=> Suppress author in the first item, Smith 2019.
=> whether the author's name in the second list item (Smith 2020) is 
shown depends on the citation style. Some styles repeat the author's 
name, others won't.

For comparison:

[cite:@Smith2019;@Smith2020; see also @Jones2018]

=> Don't suppress author in the first item, Smith 2019.
=> whether the author's name in the second list item (Smith 2020) is 
shown depends on the citation style. Some styles repeat the author's 
name, others won't.

Ahhh OK, that makes it clearer. Thanks! Sorry for the noise -- I haven't
been able to follow this thread all that closely due to other work,
though I remain interested and willing to help.

Yes, thank you; that's much better put.
