bug#25454: 25.1; improvement ftoopy-from-above-command


From: Francesco Potortì
Subject: bug#25454: 25.1; improvement ftoopy-from-above-command
Date: Sun, 15 Jan 2017 21:00:30 +0100

This is the version I use:

it copies line from above as the stock one, but when called repeatedly
it copies from further above lines.  Moreover, when called with a
numeric argument, increments all the numbers fund in the copied text by
the argument.

;; Modified from misc.el distributed with 19.30
;; by "Francesco Potortì <address@hidden>"

(defvar my-copy-from-above-lines -1)
(defvar my-copy-from-above-chars 0)
(defvar my-copy-from-above-inc 0)

(defun my-copy-from-above-command (&optional arg)
  "Copy the previous line incrementing numbers, starting just above point.

All integer numbers fetched as part of the line are incremented by ARG.
If no argument is given, numbers are left as they are.
Successive invocations of this command fetch successively previous lines.
The characters copied are inserted in the buffer before point, mark is
set to the beginning of the inserted string."
