Re: syntax highlighting for comments

[gento <gento_distefano@hotmail.com>]

Thank you very much Bruno!

I'm using this

(add-hook 'find-file-hooks
 (lambda ()
  (when (string-match "\\.jou$" (buffer-file-name))
   (setq comment-start "/")
   (font-lock-add-keywords nil '("\\(/.*\\)$" (1 font-lock-comment-
face)))
   (font-lock-mode)
  )
 )
)

and it works.

Have a nice day
