There is a elisp: gse-number-rect which can do this:
C-u M-x gse-number-rect

Re: emacs insert icrement numbers

[Chris McMahan]

I was a real fan of this function, but it has ceased to work in the
latest versions of emacs.

Does anybody have a version that works under emacs-22, or a fix for
the existing version (2004.12.22)?

Here's the error message I get:

if: Wrong number of arguments: #[(prompt &optional default)
"<a string of non-printable characters>" [n default prompt str nil string-match
"\\(\\):[ ]*\\'" replace-match format " (default %s)" ...] 8], 3

Re: emacs insert icrement numbers

[wenbinye]

the function gse-number-rectangle use function read-number which is not
compatible
with old version. You have to change the line marked as following:

  (interactive
   (list
    (region-beginning) ; start
    (region-end) ; end
    (if (functionp 'read-number)
;; change this line  (read-number "First number [1]: " t "1") to this
        (read-number "First number [1]: " 1) ; start-at
      (string-to-int (read-string "First number [1]: " nil nil "1"))) ;
start-at
    (read-string "Suffix: " nil 'gse-number-rectangle-history) ;
suffix-text
    current-prefix-arg)) ; prefix

Well I don't have gse-number-rect, and I bet it'll be faster to write
the following than to use google...

(defun insert-numbers (min max)
  (interactive "nFrom: \nnTo: ")
  (while (<= min max) (insert (format "\n%d " min)) (setq min (+ 1 min))))

0
1
2
3

It's also possible to record the left margin, and to copy it on each line:

(defun insert-numbers (min max)
  (interactive "nFrom: \nnTo: ")
  (let ((margin (buffer-substring (save-excursion (beginning-of-line) (point))
                                  (point))))
    (when (<= min max)
        (insert (format "%d " min))
        (setq min (+ 1 min))
        (while (<= min max)
          (insert (format "\n%s%d " margin min))
          (setq min (+ 1 min))))))

==> 0 
==> 1 
==> 2 
==> 3

With latest versions (>=22), you can use \,form in the the substitutions.

For example, select a region and:

M-x replace-regexp RET \(.*\) RET 
    \,(progn(defvar n 0)(format "%3d " (incf n)))\1 RET

  1 NOTE: The most fundamental particles in this product are held
  2 together by a "gluing" force about which little is currently known
  3 and whose adhesive power can therefore not be permanently
  4 guaranteed.

Thanks for the code! I'm saving it as part of my "I've got to learn

Or

M-x replace-regexp RET ^ RET \,\#  

[there are two spaces after the '\#'. I don't know why it needs 2 rather
than one, though]

To distinguish this from
\,\#1
for example.  The space terminates \#.

emacs insert icrement numbers

[Step0ut]

Hi everyone,

I am using emacs as an editor for c++ and latex.
I am using the command Ctrl-xrt to insert rectangles (usually numbers) quite
often.
My question is:
Is it possible to insert numbers that increament in each line?
e.g.  0
       1
       2
       ...
       99

Alternatively I was also thinking if it is possible to replace an existing
string (M-x replace-regexp) with an icrement number. It will do the job as
well.

Here's some lisp I wrote to do this 20 years ago which I still use today...

(defun bw-inc-column (column start inc begin end)
  "Increment the numbers in a column.
The numbers are created in COLUMN and start with number START and are
incremented by INC in the region.
In programs, the region is defined by BEGIN and END.
Note that the columns are basically defined by `forward-word' so any space or
punctuation character will split columns."
  (interactive "nColumn: \nnStart: \nnIncrement: \nr")
  (save-restriction
    (save-excursion
      (narrow-to-region begin end)
      (goto-char (point-min))

        (while (< (point) (point-max))

          (let ((begin (point)))
            (forward-word 1)

            (message (format "n=%d" n))
