how to set c-offsets-alist

how to set c-offsets-alist

[Subhakar K S]

How do I set the values for various c/c++  syntactic
symbols using "c-offsets-alist".

I want to set this values in my ~/.emacs file.

Any example peice of ~/.emacs will be helpful for
me to copy paste.

thanks,
Subhakar.

I have a similar question... is there a way to set c-offsets-alist on a
file-by-file basis
using the headline comments (or whatever they are called) like this:
/* -*- Mode: C; tab-width: 8; indent-tabs-mode: t; c-basic-offset: 8 -*-
*/

Here is an example .emacs I found at :
http://cc-mode.sourceforge.net/cc-mode.html

;; Here's a sample .emacs file that might help you along the way.  Just

(defconst my-c-style
  '((c-tab-always-indent        . t)
    (c-comment-only-line-offset . 4)
    (c-hanging-braces-alist     . ((substatement-open after)
                                   (brace-list-open)))
    (c-hanging-colons-alist     . ((member-init-intro before)
                                   (inher-intro)
                                   (case-label after)
                                   (label after)
                                   (access-label after)))
    (c-cleanup-list             . (scope-operator

                                   (substatement-open . 0)
                                   (case-label        . 4)
                                   (block-open        . 0)
                                   (knr-argdecl-intro . -)))
    (c-echo-syntactic-information-p . t)
    )
  "My C Programming Style")

;; offset customizations not in my-c-style
(setq c-offsets-alist '((member-init-intro . ++)))

;; Customizations for all modes in CC Mode.
(defun my-c-mode-common-hook ()
  ;; add my personal style and set it for the current buffer
  (c-add-style "PERSONAL" my-c-style t)
  ;; other customizations
  (setq tab-width 8
        ;; this will make sure spaces are used instead of tabs
        indent-tabs-mode nil)
  ;; we like auto-newline and hungry-delete
  (c-toggle-auto-hungry-state 1)
  ;; keybindings for all supported languages.  We can put these in
  ;; c-mode-base-map because c-mode-map, c++-mode-map, objc-mode-map,

  (define-key c-mode-base-map "\C-m" 'c-context-line-break)
  )

(add-hook 'c-mode-common-hook 'my-c-mode-common-hook)

I hope that helps...

setting c-offsets-alist variables from "headline"?

[Dave Lawrence]

Is there a way to set c-offsets-alist on a file-by-file basis
using "headline comments" (or whatever they are called) like this:
/* -*- Mode: C; tab-width: 8; indent-tabs-mode: t; c-basic-offset: 8 -*-
*/

For example, is there any was to set defun-block-intro to 1
(as is done in a .emacs file entry below) using comments in a file?

    (c-offsets-alist            . ((arglist-close . c-lineup-arglist)
                                   (substatement-open . 0)
                                   (case-label        . 4)
                                   (block-open        . 0)
                                   (defun-block-intro . 1)
                                   (knr-argdecl-intro . -)))

Thanks!!!

Check out the "Local Variables in Files" node of the emacs manual:

C-h i m emacs <RET> m file <spc> variables <RET>

Here is my example from my .emacs file.  Read the comment to learn more
about customizing the values.

;If you go to a line in a c++ file and type C-c C-o it will tell you the name
;of the syntactic symbol to use in c-set-offset (or below in the list).

(setq c-style-alist
      (append '(("ETX"
                 (c-basic-offset . 2)
                 (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 . +)
