Customizing a default indentation style for C++

Question

I use the default style linux (snippet from here)

;; set indentation style linux for c++
(setq c-default-style "linux"
          c-basic-offset 4)

But I can't get it to work with the style setting which sets zero indent for namespaces (from this question)

(defconst my-cc-style
  '("cc-mode"
    (c-offsets-alist . ((innamespace . [0])))))

(c-add-style "my-cc-mode" my-cc-style)

Once I choose my-cc-style with C-c . RET my-cc-mode RET, I get the strange brace indent back which the first setting removes, i.e. like this:

virtual string_type do_falsename() const
    {

Is there a way to keep everything from the default style, and change only the namespace indentation?

Answer 1

Defining your style based on linux instead of cc-mode should help.

(defconst my-cc-style
 '("linux" ; this is inheritance from the linux style
   (c-offsets-alist . ((innamespace . [0])))))
