Hi All,
I might be missing something obvious on this one, but I couldn't
figure out a way to do it and as far as I understand the code, I see
no way to break the loop in `LaTeX-arg-biblatex-cites'. So I report.
When RefTeX is plugged into AUCTeX, trying to insert a `biblatex'
citation list with `TeX-insert-macro' will call
`LaTeX-arg-biblatex-cites' and, as far as I can tell, there is no way
to tell that function no further arguments are required. For sure,
one can interrupt the cycle from the call to `reftex-citation' with
"C-g" or "q", but then one also loses the citation altogether making
the attempt futile.
To reproduce starting with `emacs -Q'. Some setup:
#+begin_src emacs-lisp
(add-to-list 'load-path "~/.emacs.d/elpa/auctex-13.2.1")
(load "auctex.el" nil t t)
(load "reftex.el" nil t t)
(setq TeX-parse-self t)
(setq TeX-auto-save t)
(setq reftex-plug-into-AUCTeX t)
(add-hook 'LaTeX-mode-hook 'turn-on-reftex)
(setq reftex-use-external-file-finders t)
#+end_src
Visit a file with contents:
#+begin_src latex
\documentclass{article}
\usepackage{biblatex}
\addbibresource{biblatex-examples.bib}
\begin{document}
\end{document}
#+end_src
Now, use `TeX-insert-macro' to insert a biblatex qualified citation
list, say `\cites': "C-c RET cites RET". You are prompted for a
regexp, as usual, you can enter it, get a list of results, select one
with RET. And, you are prompted again for a new regexp, you can enter
it and select a new candidate, etc. etc. The only chance you get to
break the loop is at the regexp prompt, where you can leave it with
"C-g" or "q", but then you lose the whole citation command, which is
deleted.
Indeed, the loop in `LaTeX-arg-biblatex-cites' takes the form:
#+begin_src emacs-lisp
(while items
;; ... handling of optional arguments
(setq items (if (and (fboundp 'reftex-citation)
(fboundp 'reftex-plug-flag)
(reftex-plug-flag 3))
;; Use RefTeX when enabled.
(reftex-citation t)
;; Multiple citation keys in each argument are allowed.
(TeX-completing-read-multiple
(TeX-argument-prompt optional prompt "Key(s)")
(LaTeX-bibitem-list))))
;; ... macro/argument is inserted, but value of `items' is left untouched
)
#+end_src
So, since `items' is not touched after it is set with
`(reftex-citation t)', leaving the loop would require a way for
`reftex-citation's UI to return nil. I don't see how. But, again, I
may be missing something...
Best regards,
Gustavo.
