A Solution to the Emacs Tab problems

If you use emacs, your code may be forced into a 2-char tab width format. That format does not meet our readability standards. Thanks to rhayward, we have some info that shows how to adjust the tab and format settings.

Sample Code

The three variables which can get a good result are.

(defun-block-intro . 0)
(statement-block-intro . 8)
(substatement . 8)

You can access them by typing C-c C-o, but  must entered values as
- -- + ++ 0....  or enter numbers 2 4 8....
This works just for the secession.

You can also place your cursor on a line hit tab and find out
what the name of that variable is, like : syntax ((defunc-block-intro . 692 
)),  indent 4


Although the permanent to set them is the .emacs file below. This is an
example from emacs manual  page.... Browse manuals with info, choose cc-mode.

(custom-set-variables
  '(standard-indent 8)
  '(inverse-video t))
(custom-set-faces)

;; Here's a sample .emacs file that might help you along the way.  Just
;; copy this region and paste it into your .emacs file.  You may want to
;; change some of the actual values.
