[AUCTeX-devel] Any equivalent to `reftex-label' in AUCTeX

[Arash Esbati]

Hi all,

caption.sty has an undocumented command `\captionbox' with the following
syntax:

    \captionbox[list entry]{heading}[width][inner-pos]{contents}
    \captionbox*{heading}[width][inner-pos]{contents}

`heading' contains the caption text and the `\label{}'.  Currently, I
have the following code in `caption.el' to implement this command:

--8<---------------cut here---------------start------------->8---
(defun LaTeX-arg-caption-captionbox (optional &optional prompt)
  "Query for the arguments of `\\captionbox' incl. a label and
insert them."
  (let* ((caption (TeX-read-string (TeX-argument-prompt optional prompt 
"Caption")))
         (label   (if (fboundp 'reftex-label)
                      (reftex-label nil t)
                    (TeX-read-string (TeX-argument-prompt optional prompt 
"Label"))))
         (width   (completing-read (TeX-argument-prompt t prompt "Width")
                                   (mapcar (lambda(elt) (concat TeX-esc (car 
elt)))
                                           (LaTeX-length-list))))
         (inpos   (completing-read (TeX-argument-prompt t prompt "Inner 
position")
                                   '("c" "l" "r" "s")))
         (heading (format "%s\\label{%s}" caption label)))
    (LaTeX-indent-line)
    (TeX-argument-insert heading optional)
    (cond (;; 2 optional args
           (and width (not (string-equal width ""))
                inpos (not (string-equal inpos "")))
           (insert (format "[%s][%s]" width inpos)))
          (;; 1st empty opt. arg, 2nd opt. arg
           (and (string-equal width "")
                inpos (not (string-equal inpos "")))
           (insert (format "[][%s]" inpos)))
          (;; 1st opt. arg, 2nd empty opt. arg
           (and width (not (string-equal width ""))
                (string-equal inpos ""))
           (insert (format "[%s]" width)))
          (t ; Do nothing if both empty
           (ignore)))
    (LaTeX-fill-paragraph)))

(TeX-add-style-hook
 "caption"
 (lambda ()
   '("captionbox"  [ "List entry" ] (LaTeX-arg-caption-captionbox) t)))
--8<---------------cut here---------------end--------------->8---

My question is, does AUCTeX has something equivalent to `reftex-label'
or should I just read the label as a string?

Best, Arash
