Alter a built-in style (C++, want to change where "access labels" are placed)

Alter a built-in style (C++, want to change where "access labels" are placed)

[Eric Lilja]

Hi!
Sorry for starting a new thread, hope this isn't bad netiquette.

My question: In my C++ mode hook I set the style to "ellemtel" with
(c-set-style "ellemtel")

I like how it indents except for where it place access labels (public,
private and protected in classes).
I want to change this behaviour but keep the rest. According to CC Mode
manual this seems very possible:
"If none of the built-in styles is appropriate, you'll probably want to
create a new style definition, possibly based on an existing style. To
do this, put the new style's settings into a list with the following
format - the list can then be passed as an argument to the function
c-add-style."

I look at the provide sample .emacs file but I can't even make this
defconst compile and I don't know  what I should do when it does.

(defconst my-c++-style
  '(
    (c-offsets-alist . ((access-label . -)))) "My C++ Programming
style")

Compiling file c:/cygwin/home/hivemind/.emacs at Sat Nov 25 22:38:59
2006
.emacs:137:1:Error: End of file during parsing

And how do I "inherit" all settings from ellementel and override the
one as constructed in the defconst?

Tried this:
(defconst my-c++-style
  "ellemtel"
  '(
    (c-offsets-alist . ((access-label . -)))
  )
)
;(c-add-style "PERSONAL" my-c++-style)

(defun my-c-mode-common-hook ()
  ;; my customizations for all of c-mode and related modes
  (setq c-basic-offset 3)
  (setq-default indent-tabs-mode nil) ; Use spaces, not tabs, for
indentation.
  (delete-selection-mode 1) ; Maybe on by default on windows and off by
default on solaris?
  )
(add-hook 'c-mode-common-hook 'my-c-mode-common-hook)

(defun my-cpp-mode-hook ()
  (c-set-style "ellemtel")
)
(add-hook 'c++-mode-hook 'my-cpp-mode-hook)

However, it doesn't like c-add-style:
c-add-style: Wrong type argument: listp, "ellemtel"
and thus I cannot test it in c-set-style

Any ideas?

This seems to work!
(defun my-c-mode-common-hook ()
  ;; my customizations for all of c-mode and related modes
  (setq c-basic-offset 3)
  (setq-default indent-tabs-mode nil) ; Use spaces, not tabs, for
indentation.
  (delete-selection-mode 1) ; Maybe on by default on windows and off by
default on solaris?
  )
(add-hook 'c-mode-common-hook 'my-c-mode-common-hook)

(defun my-cpp-mode-hook ()
  (c-set-style "ellemtel")
  (c-set-offset 'access-label '--)
  (c-set-offset 'topmost-intro '-)
  (c-set-offset 'inline-open '-)
)
(add-hook 'c++-mode-hook 'my-cpp-mode-hook)
