Tab questions

Tab questions

[Todd Wylie]

Hi-

I have a couple of questions about tab stops.
1: Is there a way to load edit-tab-stops from the .emacs file? Or must I M-x 
edit-tab-stops each session?
2: I'm not too clear on how tabs are working. If I edit-tab-stops from 8 
characters to 5 for the first tab stop and then use C-f it will traverse all 
5 spaces for the first tab stop -- however, it will jump all 8 spaces at the 
same time at the next (unedited) tab stop. Are edited tab stops akin to 
untabifying tabs (i.e. literal spaces)? I have the O'reilly GNU emacs book 
but his section isn't very helpful... thanks.

best wishess,
Todd

Read about the load path and require.  If it is not covered in the O'reilly GNU emacs book look at the elisp reference manual.  I haven't read the O'reilly book I just get my information from the elisp reference and the help.
http://www.gnu.org/manual/elisp-manual-21-2.8/html_mono/elisp.html for version 21.1 and later
http://www.gnu.org/manual/elisp-manual-20-2.5/html_mono/elisp.html for version 20

M-x customize-variable RET tab-stop-list RET

Don't forget to save your changes.

There are two completely separate concepts: (1) where does the cursor
go when you hit TAB or M-i, (2) where does Emacs put tab characters
in your buffer.

The variable tab-width controls the latter.

(shameless plug)  You might also try the Emacs keybinding tutorial,
which used to be on my homepage but that is gone now.  Maybe Google
still has a copy.  I hope to reinstate my homepage asap, but I'm
quite busy at the moment...

May not be the answer to your question, but I use the variable
tab-stop-list for this purpose.

The following crude function (wrote a while back.  Never tried to make
it better.) sets the tab stops at places in the interval 2-120.

I have bound it to a key and a menu item.

(defun upn-set-tab-stops (spaces)
  "Sets tab stops at fixed intervals."
  (interactive "nSize of interval: ")
  (if (or (< spaces 2) (> spaces 120))
      (princ "Arg should be in the range 2-120" (active-minibuffer-window))
    (setq tab-stop-list nil)
    (let ((cur-column spaces))
      (while (< cur-column 121)
        (setq tab-stop-list (append tab-stop-list (list cur-column)))
        (setq cur-column (+ cur-column spaces))))
    (princ "Tab stops are set at " (active-minibuffer-window))
    (pp tab-stop-list (active-minibuffer-window))))
