org-cite and pandoc

org-cite and pandoc

[Eric S Fraga]

Dear list,

I am needing to export a document, written in org using the new cite
syntax, to pandoc (native).  The export fails.  I realise that org-cite
is new and I don't expect the export to process any [cite:@key] lines
properly but it would be good to have the export at least generate a
pandoc file I can then work with.  Is this possible?

I recognise fully that ox-pandoc is in contrib so I don't expect
anything as such!  In the meantime, I'll simply remove all [cite:]
entries but I thought I'd raise this issue.

The error (with paths elided and lines truncated) I get is:

--8<---------------cut here---------------start------------->8---
Debugger entered--Lisp error: (wrong-type-argument stringp ("..."))
  split-string(("...") "\n")
  (cons (car it) (split-string val "\n"))
  (list (cons (car it) (split-string val "\n")))
  (progn (list (cons (car it) (split-string val "\n"))))
  (if val (progn (list (cons (car it) (split-string val "\n")))))
  (let ((val (plist-get info (cdr it)))) (if val (progn (list (cons (car it) (split-string val "\n"))))))
  (closure ((info :export-options nil :back-end ...
  mapcar((closure ((info :export-options nil :back-end #s(org-export-backend :name pandoc

Thank you,

Yeah, ideally ox-pandoc would be updated to support org-cite.

I also, FYI, submitted an issue to pandoc awhile ago to update it's
org-cite support (it has support for an early draft).

Indeed but even exporting without error would be good, assuming of
course that the error I reported is actually due to org-cite.  It might
not be; I've never exported to pandoc before!  This is for a journal
that expects submissions in pandoc (never had this before) which (in
some ways) is nice as at least it's not Word...

Perhaps a useful workaround would be to first "export to Org" (with
org-org-export-as-org)?
AFAICS this replaces the Org cites with their export
processor-rendered counterparts, e.g.,
with suitable Natbib cite commands when the
#+cite_export: natbib
line is used.

best regards,
András

Excellent suggestion!  Thank you.

Doing so clearly indicates that my problem is *not* with org-cite but
with ox-pandoc.  Strange.

I had mentioned that ox-pandoc was in org-contrib; it is not.  It is in
MELPA.

Okay, I will need to investigate further.  There must be something in my
configuration that is affecting ox-pandoc as others seem to be using it
just fine.

Thanks again,
eric

Never heard of that before either; very cool!

After some investigation...

It seems that the presence of the #+bibliography: line is what causes
ox-pandoc to fail.  Removing this line is sufficient for me to get the
export working.

Thanks again,
eric

Ignore this, by the way; I meant to type markdown, not pandoc.

See my update... <blush> markdown, not pandoc.  Although pandoc's native
format is quite useful, just not readable. ;-)

By the way, ox-md also fails if there is a #+bibliography
line.  Removing it allows for the export.  Very strange.

Would you have an ECM? I cannot reproduce it.

Unfortunately, I cannot reproduce it with emacs -Q [1].  Has to be
something in my configuration but I have no idea what.  No time at
present to bisect etc. but I will in due course hopefully.

Sorry for the noise.

thank you,
eric

[1] the one real disadvantage of using Emacs as my window manager,
     i.e. exwm, is the hassle involved in actually running Emacs with
     -Q. :-(
