chevrons for D templates in emacs

[Andrei Alexandrescu]

With the help of Pascal J. Bourguignon on the gnu.emacs.help newsgroup I 
got some chevrons working for D templates. The current version has quite 
a few shortcomings (no proper nesting and electric behavior could be 
better) but it does get us started towards finding a comprehensive 
solution.

Paste this into your ~/.emacs (assuming you already use Bill Baxter's 
d-mode and of course emacs):

(defun d-chevrons ()
   (font-lock-add-keywords
    nil '(("\\(!(\\)[^()]*\\()\\)"
           0 (progn
               (compose-region (match-beginning 1) (match-end 1)
                               ?« 'decompose-region)
                               (compose-region (match-beginning 2) 
(match-end 2)
                                               ?» 'decompose-region)
               nil))))
   (font-lock-mode 1))

(add-hook 'd-mode-hook 'd-chevrons)


The result looks pretty darn yummy.
