emacs 20.7.1 forgets c-basic-offset after find-file

emacs 20.7.1 forgets c-basic-offset after find-file

[Kurumi]

I'm running emacs 20.7.1 in Redhat 7.1, Linux 2.4.2-2.

I have a modified .emacs file (included) to give me some key
bindings matching the other machines I work on. I also
have c-basic-offset set to 3.

What's annoying is that after I do a "find file" (aka
open a file), emacs resets c-basic-offset to 2. This
is immediately apparent whenever it auto-indents a
line of code. When I do Customize -> specific option
-> c-basic-offset, it is indeed at 2, and I have to
change it and save it.

In other words:
1. start emacs; c-basic-offset is at 3
2. open a file; c-b-o changes to 2. However, .emacs
still shows 3
3. re-edit the value in "customize"; c-b-o back at 3
4. open another file; c-b-o back to 2

As you can imagine, this is irritating. In a previous
installation of 7.1/20.7.1, I didn't have this
problem. Any ideas what's causing it?

My .emacs is shown below. Thanks!

Scott

c-mode is overwriting your setting when it loads, so you need to set
your basic offset in a mode-hook.

I don't know the customization interface (if any) to the c-mode hook,
but you can add this to your .emacs:

(defun kurimi-c-mode-setup ()
  (setq c-basic-offset 3)
  ;; other c-mode customizations here
  )

(add-hook 'c-mode-hook 'kurimi-c-mode-setup)

Thanks, that worked. (For C++, I included an add-hook for 
'c++-mode-hook.)

hi,

as you open a new file in c-mode the variable c-basic-offset becomes
local in that buffer and receives its value from somwhere else than
your .emacs file. look at the documentation (C-h v c-basic-offset
RET).
