Defining syntactic symbols

Defining syntactic symbols

[Peter Lee]

Hello all.

I'm having a problem with cc-mode handling things macros inside class
definitions such as DECLARE_MESSAGE_MAP(class).

I'm having the same problem with csharp-mode and attributes such as
[ComVisible(true)]
[Guid("6674C3CF-1118-40f2-B7F2-CBA3D863082C")]

Following either of these the indentation is off or in the case of
csharp I get syntactic errors.

If I put a semi-colon after the attributes or the macro's the problem
goes away.

I assume I need to extend cc-mode to handle this syntax, but I'm not
sure how to go about it.

Any help would be greatly appreciated.

I wanted to add that I'm using the following for csharp support:

;;; csharp-mode.el --- csharp-mode
;; Authors: 2002 Dennis Haney <davh@davh.dk>
;;          2000 Brad Merrill <zbrad@cybercom.net>
;; Version: 1.05

More info, I found the following in csharp-mode.el that looks to be
what I need to change:

(defconst c-Csharp-attrib-key (concat "\[" c-symbol-key "\\(([^)]*)\\)?\]"))

(defconst c-Csharp-class-key
  (concat
   c-Csharp-attrib-key
  "\\(?:" 
   "\\("
   "new\\|"
   "public\\|"
   "protected\\|"
   "internal\\|"
   "private\\|"
   "abstract\\|"
   "sealed"
   "\\)"
   "\\s +\\)*"
   "\\(struct\\|class\\)\\s +"
   c-symbol-key                         ;name of the class
   "\\(\\s *:\\s *" c-symbol-key        ;maybe followed by parent
   "\\(\\s *,\\s *" c-symbol-key "\\)*"
   "\\)?"
   ))

I'm guessing I just need to change the regex for c-Csharp-attrib-key
to be able to handle recognize:

[ComVisible(true)]
[Guid("6674C3CF-1118-40f2-B7F2-CBA3D863082C")]

But all my attempts so far have not been successful. If any regex
gurus out there can help it would be appreciated.

Or is the completely wrong place to be doing this?
