[AUCTeX-devel] Support for biblatex in Reftex

[Arash Esbati]

Hi all,

after the discussion here [1], I suggest to apply this patch to
`reftex-cite-format-builtin':

      ((?\C-m . "\\cite{%l}")
       (?p    . "\\cite{%l}")
--8<---------------cut here---------------end--------------->8---

It can be activated in biblatex.el with something like this:

--8<---------------cut here---------------start------------->8---
(when (fboundp 'reftex-set-cite-format)
  (if (or (LaTeX-provided-package-options-member "biblatex" "natbib")
          (LaTeX-provided-package-options-member "biblatex" "natbib=true"))
      (reftex-set-cite-format 'natbib)
    (reftex-set-cite-format 'biblatex)))
--8<---------------cut here---------------end--------------->8---

I'm not a biblatex user, maybe serious users can give a comment on the
chosen commands and key bindings.  I tried to keep close to natbib.

Best, Arash
