Move selection up and wown

[pistacchio]

Hi, one thing that I always configure my editor to have is Ctrl-Cmd+Up / Ctrl-Cmd+Down to move the current line where the caret or the current selection up and down. See the gif for what I mean.

Ho to do this in Spacemacs? Thanks

There's a Move Text Transient State under SPC x J for move down and SPC x K for move up.

It's using the https://github.com/emacsfodder/move-text package

If your using the Emacs editing style, then it probably should work as expected.

But if your using the Evil (vim) editing style, then you'll have to use another package. The author said:

I don't explicitly support eVil mode so if this is something you'd​ like to see done quickly, please submit a patch / pull-request

source: https://github.com/emacsfodder/move-text/issues/11#issuecomment-309384232

If your using the Evil editing style, then you might want to use the drag-stuff package. https://github.com/rejeep/drag-stuff.el

There's no mention of evil support on the first page, but here's a merged PR where they fixed something evil-mode related: Fixes evil-mode dragging and adds evil-mode recipes https://github.com/rejeep/drag-stuff.el/pull/13

I just did some quick testing and it seems to move any lines with either of these types of selections on them:

• v (evil-visual-char)
• V (evil-visual-line)

It doesn't seem to work with C-v (evil-visual-block) selections.

To install the drag-stuff package, add it to the dotspacemacs-additional-packages variable near the top of your .spacemacs file.

   dotspacemacs-additional-packages '(drag-stuff)

Then in the dotspacemacs/user-config section add:

    (drag-stuff-mode t)
    (global-set-key (kbd "<C-S-up>") 'drag-stuff-up)
    (global-set-key (kbd "<C-S-down>") 'drag-stuff-down)

Thanks @duianto drag-stuff works great. Just a remark:

(kbd "<C-S-up>")
(kbd "<C-S-down>")

should be:

(kbd "C-S-k")
(kbd "C-S-j")

instead, because:

• < is not recognized and throws an error in Spacemacs
• using k and j is more idiomatic in Evil mode. (That being said, up and down is what @pistacchio originally asked for.)

Cheers, Nicolas

< is not recognized and throws an error in Spacemacs

I'm not getting any errors on either the Spacemacs master or develop branches, with:

    (global-set-key (kbd "<C-S-up>") 'drag-stuff-up)
    (global-set-key (kbd "<C-S-down>") 'drag-stuff-down)

I also tried binding them like this, and it worked as well:

  (global-set-key (kbd "C-S-<up>") 'drag-stuff-up)
  (global-set-key (kbd "C-S-<down>") 'drag-stuff-down)

Spacemacs seems to have had keys bound using angle brackets for at least 3 or 4 years (that seems to be when the following lines where last touched), for example, zooming with the mouse wheel:

using k and j is more idiomatic in Evil mode.

  (global-set-key (kbd "C-S-k") 'drag-stuff-up)
  (global-set-key (kbd "C-S-j") 'drag-stuff-down)

That's a good suggestion, it reduces the need to move the right hand to the cursor keys. 👍

Another great solution imho came from VanLaser to use evil commands for movement, which also supports moving a selection n lines at once:

(define-key evil-visual-state-map (kbd "M-<down>") (concat ":m '>+1" (kbd "RET") "gv=gv"))
(define-key evil-visual-state-map (kbd "M-<up>")   (concat ":m '<-2" (kbd "RET") "gv=gv"))
(define-key evil-normal-state-map (kbd "M-<down>") (concat ":m +1" (kbd "RET") "=="))
(define-key evil-normal-state-map (kbd "M-<up>")   (concat ":m -2" (kbd "RET") "=="))

But I'd be happy either way as long as spacemacs doesn't come with a broken transient state if you chose to use evil.

A PR has been opened: Replace move-text with drag-stuff #14449

If it's accepted, then the drag-stuff package don't need to be added to the additional packages list.

Thanks for sharing. This is excellent. I’m using this modified to use the j and k keys, but otherwise perfect for me.
