[implementations-list] vimpulse interaction with cua increasing number feature

Mon Mar 29 22:31:54 CEST 2010

Hi Fabian!

Are you using the Subversion version of Vimpulse? You'll need to point
your SVN client to the address below if you want the latest bugfixes
before release.

Fixed in SVN revision 159.

The Cua function will only work on Cua rectangles. However, since
Vimpulse's block selections are rectangle compatible, an equivalent
rectangle command can be written as follows:

    (require 'rect)

    (defun my-sequence-rectangle (first incr format)
      "Insert increasing numbers at beginning of each line."
      (interactive
       (list (if current-prefix-arg
                 (prefix-numeric-value current-prefix-arg)
               (string-to-number
                (read-string "Start value: (0) " nil nil "0")))
             (string-to-number
              (read-string "Increment: (1) " nil nil "1"))
             (read-string "Format: (%d) ")))
      (when (= (length format) 0)
        (setq format "%d"))
      (apply-on-rectangle
       (lambda (start-col end-col count-var)
         (move-to-column start-col)
         (insert (format format (eval count-var)))
         (set count-var (+ (eval count-var) incr)))
       (region-beginning) (region-end) 'first)
      (vimpulse-visual-mode -1))

    (vimpulse-vmap (kbd "M-n") 'my-sequence-rectangle)

If you compare it with `cua-sequence-rectangle', you'll see they are
quite similar; the Cua function uses `cua--rectangle-operation' for
applying a lambda function on each line, whereas this function uses
`apply-on-rectangle' from rect.el.

Hope this helps!
