[Ns-developers] emacs indentation innamespace

[Nicola Baldo]

Hi all,

as many of you, I am using emacs for editing ns3 code. The "gnu" 
indentation style mostly conforms to the ns3 coding guidelines, but has 
a few quirks. One of these is that code after "namespace ns3 {" is 
indented, while the ns3 coding style says it should not. This is 
annoying. Does anybody out there have a solution to this problem?

My experience is:

1) with a ns3 source file already opened, you can type 'C-c C-o 
innamespace <ret> 0 <ret>' and get the desired behavior

2) I tried to make the setting permanent by adding the following code to 
my ~/.emacs:

(defun my-c-mode-common-hook ()
   (c-set-offset 'innamespace 0))
(add-hook 'c-mode-common-hook 'my-c-mode-common-hook)

this works for normal C source files, but doesn't work when opening a 
ns3 source code file. I think this is due to the option 'c-file-style: 
"gnu";'  in the emacs modeline at the beginning of the source code file: 
I get the impression that it overrides the innamespace setting in 
.emacs. In fact, if I remove 'c-file-style: "gnu";'  from the modeline, 
the next time I open the file I get the desired behavior.

Any hints? It's annoying to do procedure 1) for every file you open...

Regards,

Nicola
