问题
I would like to know how can I get the suggestion when I do a \cite in Emacs-AUCTeX. The minibuffer tells me when I do C-c [ that:
No valid bibliography in this document, and no default available
So how can I set this default? I have a separated file with my bibtex references that is called by a master document, and I want the suggestion for any of the other files included.
回答1:
The variable reftex-default-bibliography is what defines the default bibliography to use. I don't do much with mult-file documents, do you have reftex-plug-into-AUCTeX turned on?
回答2:
Have you tried: Ref -> Parse Dokument -> Entire Document? That solved the problem for me.
回答3:
Yes, modifying this variable is a solution (I don't know if it is the "best solution"). I go to the ref menu -> Customize -> Browse Reftex Group -> Reftex Citacion Support -> Reftex Default Bibliography and then I add the path to the bib file (without the .bib extension) and it works!! These options create this in the init file:
(custom-set-variables
'(reftex-default-bibliography (quote ("D:/mybibdirectory/mybibfile"))))
(custom-set-faces
)
Well, perhaps that it works now that suggestions are going to appear in every document that I write. It would be good have a solution only for this document.
Reading the help file of reftex (reftex->finding files) also mentions make the next modifications in order to get the suggestions:
(setq reftex-bibpath-environment-variables
'("D:/mybibdirectory/"))

You may also try the solution mentioned in Re: auctex - no valid bibliography?. It worked for me.
(It might help to check whether you have kpsewhich installed, before attempting to use this fix. The following command should output its path if you do have it installed:
$ which kpsewhich
)
回答5:
When in the buffer of your non-master file, try to query for the name of a master file (again) with C-c _ (Control C + underscore) as explained in auctex manual
This will add the local variable TeX-master to the end of your file. Save your file, restart emacs and load your file again. Hopefully, you can now get references from the bibliography stated in your master file by calling C-c [ in the subfile.
Mysteriously, when I do this manually without letting auctex query for it, it does not work. I cannot see how the end result is different in the auto directory either. But somehow letting auctex query for the value made it work for me.
