;;; Commentary:

;; This file adds support for `shortvrb.sty'.

;; XXX: We might want provide users with the possibility to activate
;; something like this for any file (incl. Plain TeX).  That would
;; bring us one step closer to the goal of displaying texbook.tex
;; without font locking going haywire.

;; FIXME: The code does not work for preview.dtx because in that file
;; the style list is empty.  In its master file, preview.drv, it
;; works, however.  However, even if the style file is loaded by hand,
;; it fails to fontify verbatim text in the documentation parts of the
;; file.

;;; Code:

(require 'tex)
(require 'tex-style)

;; Silence the compiler:
(declare-function font-latex-add-to-syntax-alist
                  "font-latex"
                  (list))

(TeX-add-style-hook
 "shortvrb"
 (lambda ()

   ;; Ispell: Add entries to `ispell-tex-skip-alist':
   (when LaTeX-shortvrb-chars
     (TeX-ispell-skip-setcar
      (mapcar (lambda (char)
                (let ((str (char-to-string char)))
                  (cons str str)))
              LaTeX-shortvrb-chars)))

   ;; Fontification
   (when (and LaTeX-shortvrb-chars
              (featurep 'font-latex)
              (eq TeX-install-font-lock 'font-latex-setup))
     (font-latex-add-to-syntax-alist
      (mapcar (lambda (char) (cons char "|"))
              LaTeX-shortvrb-chars))))
 TeX-dialect)
