How to get \cref to print "Fig." in emacs?

Question

I'm having trouble using \cref in emacs' AUCTeX + RefTeX mode. The pdf shows the reference to a picture as "section 1.3" instead of "Fig.1a" (see snapshot below) as it should, when \usepackage{cleveref} is loaded in the preamble of the main.tex file.

I've read these 2 discussions: link-1, link-2, and I have added the following lines to my .emacs file but can't notice any change in emacs' behaviour.

;;emacs RefTeX
(setq reftex-ref-macro-prompt nil) ;skips picking the reference style

;code taken from SX "Cleveref: AUCTeX and RefTeX set-up"
(eval-after-load
    "latex"
  '(TeX-add-style-hook
    "cleveref"
    (lambda ()
      (if (boundp 'reftex-ref-style-alist)
      (add-to-list
       'reftex-ref-style-alist
       '("Cleveref" "cleveref"
         (("\\cref" ?c) ("\\Cref" ?C) ("\\cpageref" ?d) ("\\Cpageref" ?D)))))
      (reftex-ref-style-activate "Cleveref")
      (TeX-add-symbols
       '("cref" TeX-arg-ref)
       '("Cref" TeX-arg-ref)
       '("cpageref" TeX-arg-ref)
       '("Cpageref" TeX-arg-ref)))))

Can someone help me out, please?

Answer 1

The issues you're experiencing are not related to emacs, and they are only indirectly related to cleveref. You need to do the following:

• In the main figure, interchange the order of \caption and \label: the \caption statement must come before the \label statement.

• Provide \caption statements for each of the two subfigure environments. Be mindful of the fact that the \caption statements must come before the \label statements.

• Fix the argument of the \label instruction in the second subfigure: It currently reads rame, whereas the argument of \cref is fig:rame. I suggest you change the \label statement to \label{fig:rame}.

Finally, if you need \cref to generate Fig. rather than fig., be sure to load the cleveref package with the option capitalize (capitalise works too).
