Subject: bug#4382: [PATCH] lisp/rect.el: (rectangle-number-lines): New user key binding C-x r N
Date: Wed, 09 Sep 2009 13:04:57 +0300 [thread overview]
Message-ID: <87pra0v3g6.fsf@jondo.cante.net> (raw)
[-- Attachment #1: Type: text/plain, Size: 781 bytes --]
Scott has just informaed me that his FSF assignment papers have been
processed and cleared. Based on his work at
http://www.antisleep.com/elisp/gse-number-rect.el I propose following
new feature to be added to the rect.el package.
2009-03-22 Jari Aalto <jari.aalto@cante.net>
* rect.el (rectangle-number-lines): New user function.
(rectangle-number-line-callback): New function.
(rectangle-number-line-format-history): New variable.
(rectangle-number-line-counter): New variable.
(define-key ctl-x-r-map "N" 'number-rectangle): New
user key binding. The basis of the rectangle numbering code was
lifted from gse-number-rect.el, orignally developed by Scott Evans
<gse@antisleep.com>. Used by permission (GPL).
