how to disable C++ namespace indentation

how to disable C++ namespace indentation

[chun]

In C++, I want to keep other indentations intact except for namespace
brackets, e.g.
namespace a {
struct A {
  int b;
};

void c {
  int d;
}
}

The above is what I want.  I tried (c-set-offset 'innamespace 0).
However it disables automatic indentation at every line when I hit
return.

I think the below is probably what you need. "c-offsets-alist" will be read
to add to the base indentation which is default to zero if  I remembered
right.

;; your coding style
(c-add-style "mycodingstyle"
         '((c-basic-offset . 3)
           (c-comment-only-line-offset . 0)
           (c-hanging-braces-alist . ((substatement-open before after)))
           (c-offsets-alist . ((topmost-intro        . 0)
                   (topmost-intro-cont   . 0)
                   (substatement         . 3)
                   (substatement-open    . 0)
                   (statement-case-open  . 3)
                   (statement-cont       . 3)
                   (access-label         . -3)
                   (inclass              . 3)
                   (inline-open          . 3)
                   (innamespace          . 0)
                   ))))

;; treat all tabs to spaces
(defun my-c-mode-hook ()
  (setq c-basic-offset 4)
  (setq indent-tabs-mode nil)
  (setq show-trailing-whitespace t))
;; c++ uses mycodingstyle
(defun my-c++-mode-hook ()
  (c-set-style "mycodingstyle"))

 Sorry,  forget my last words . "c-offsets-alist" will be read to find a
match for offset to add to the base indentation which is the last anchor
position of the last syntactic element.

Brilliant. It works. I did a quick merge into my existing .emacs
format like this:

(c-add-style "mycodingstyle"
             '((c-comment-only-line-offset . 0)
               (c-hanging-braces-alist . ((substatement-open before
after)))
               (c-offsets-alist . ((topmost-intro        . 0)
                                   (topmost-intro-cont   . 0)
                                   (substatement         . 3)
                                   (substatement-open    . 0)
                                   (statement-case-open  . 3)
                                   (statement-cont       . 3)
                                   (access-label         . -3)
                                   (inclass              . 3)
                                   (inline-open          . 3)
                                   (innamespace          . 0)
                                   ))))

;; c/c++ mode
(add-hook 'c-mode-common-hook
          '(lambda()
             (c-set-style "mycodingstyle")
             (setq tab-width 2)
             (setq c-basic-offset tab-width)))


Thanks so much for help!!!
