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

;; 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:
|
||
|
||
(defcustom LaTeX-shortvrb-chars nil
|
||
"List of characters toggling verbatim mode.
|
||
When your document uses the shortvrb style and you have a
|
||
\\MakeShortVrb{\\|} in your file to write verbatim text as
|
||
|text|, then set this variable to the list (?|). Then AUCTeX
|
||
fontifies |text| as verbatim.
|
||
|
||
Preferably, you should do this buffer-locally using a file
|
||
variable near the end of your document like so:
|
||
|
||
%% Local Variables:
|
||
%% LaTeX-shortvrb-chars: (?|)
|
||
%% End:
|
||
|
||
When you customize this variable to a non-nil value, then it
|
||
becomes the default value meaning that verbatim fontification is
|
||
always performed for the characters in the list, no matter if
|
||
your document actually defines shortvrb chars using
|
||
\\MakeShortVrb."
