bibmodule (again)

bibmodule (again)

[Thomas A. Schmitz]

Hi,

I don't want to sound like a whiner, but I was just wondering if  
there's any chance of having the bib module fixed. I have a paper to  
write within the next three weeks, and if bib doesn't work, I will  
have to use something else than ConTeXt. My problem is that numbered  
references do not produce any output. I attach a minimal example that  
gives the expected output in an older version of ConTeXt yet produces  
an empty citation in the most recent beta with the most recent bib  
module.

All best

Thomas

Hi,

I can't fix everything, but I believe I have made some progress.

The new structure and referencing code is totally different from
the old code and I understand less than half of it. What's worse:
I seem to be really bad at explaining to Hans all the things that
should happen wrt. references in the bib module.

Anyway:

At this point, please add these three (re)definitions:

%%%%%%%%%%%%%%%

\def\bibrefprefix{}

\def\preparebibreflist#1{\edef\bibreflist{#1}}

\def\docitation#1{%
  \iftrialtypesetting \else
    \ifdoinpututilities\else
      \doglobal\increment\citationnumber
      \expanded{\rawreference{}{cite-\jobname-\citationnumber}{#1}}%
  \fi \fi
  \expanded{\writedatatolist[pubs][bibref=#1]}}
%%%%%%%%%%%%%%%%%

If you turn cite compression off, it will now work (somewhat, at least).

With compression on, there is backward compatibility problem in mkiv
that I do not know how to deal with. Si here is the explanation and
then I hope Hans can make sense out of it.

In Thomas' example, in the first run the

  \placepublications[criterium=all]

creates a reference 'belfiorepleasure' with value '1', like so:

   \reference[belfiorepleasure]{1}

In the second run, the \cite[belfiorepleasure] uses this reference to
typeset the number '1' at that spot. Because the argument to \cite is
actually is a list of references, \cite (via \bibnumref) builds an
internal commalist of references to resolve.

If the citation compression is off, this is a direct list of refs,
and the citation essentially expands into

    \def\processitem#1{\in[#1]}
    \processcommalist[belfiorepleasure]\processitem

as said, that now works.

But if cite compression is on (which it is by default) the to be typeset
numbers need to be sorted, and this simple solution won't do. Instead,
the citation is expanded into something more like this:

    \def\therefs{}
    \def\processitem#1%
      {\doifreferencefoundelse{#1}
        {\addtocommalist{\reftypet}\therefs }
        {}}
    \processcommalist[belfiorepleasure]\processitem

This only works in mkii at the moment because in mkiv the \reftypet
expands to nothing. It is defined (in strc-ref.tex) as:

  \def\reftypet{\currenttextreference}

but it seems that the mkiv version of \doifreferencefoundelse does
not set up the \currentxxxreference macros any more. That is where
I got stuck, and I hope Hans can explain why that doesn't work, whether
it is intentional, and if it is indeed on purpose, what the correct
interface is to get at the 'text' field of a reference in mkiv.

Best wishes,
Taco

Hi Taco,

thanks a lot for looking into it! Your redefinitions make the minimal  
example work; I'll have to see how I can transfer them to my non- 
minimal files where I make extensive adaptations to the bib styles.

Wow, that's very encouraging for us mere mortals :-)

FWIW, Frank Bennett has completely written the Zotero Javascript CSL engine to
be faster and easier to maintain and extend. It's also now independently hosted
and developed.
