;;; 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-set-syntactic-keywords
"font-latex" ())
(declare-function font-latex-add-keywords
"font-latex" (keywords class))
(defvar font-latex-syntactic-keywords-extra)
(TeX-add-style-hook
"shortvrb"
(lambda ()
(TeX-add-symbols
'("MakeShortVerb" (TeX-arg-string "Character" "\\"))
'("MakeShortVerb*" (TeX-arg-string "Character" "\\"))
'("DeleteShortVerb" (TeX-arg-string "Character" "\\")))
;; 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 (featurep 'font-latex)
(eq TeX-install-font-lock 'font-latex-setup))
(font-latex-add-keywords '(("MakeShortVerb" "*{")
("DeleteShortVerb" "{"))
'function)
;; Use `font-latex-syntactic-keywords-extra' instead of
;; `font-latex-add-to-syntax-alist' so we can catch a backslash
;; within the shortvrb delimiters and make things like |xyz\|
;; work correctly:
(when LaTeX-shortvrb-chars
(dolist (c LaTeX-shortvrb-chars)
(let ((s (char-to-string c)))
(add-to-list 'font-latex-syntactic-keywords-extra
`(,(concat "\\(" s "\\)"
".*?"
"\\(" (regexp-quote TeX-esc) "*\\)"
"\\(" s "\\)")
(1 "\"") (2 ".") (3 "\"")))))
;; Tell font-lock about the update
