Dear List,
Org-mode is great and I'd like to commit to it. However, I'm held back
by the apparent fragility of data stored in org-files. For example,
it's easy to delete entire folded trees of data with just a couple of
keystrokes or a mouse click.
It there any way I can confirm all deletions of significant amounts of
data?
I've tried wimpy-del.el <http://www.emacswiki.org/emacs/wimpy-del.el>
but, although it seems to work when called directly (e.g. M-x
kill-region-wimpy) it doesn't intercept all other functions which
might cause data deletion.
I'd appreciate people's thoughts
Nick

This should not be a problem as long as you know how the undo in Emacs
works. You can even use browse-kill-ring¹ to see what you have deleted in
Emacs.

This shouldn't be a big problem, because you have automatic
backup of your org and other files, right?
Combining this with the builtin undo and setting up Emacs' own
backup properly (http://www.emacswiki.org/emacs/ForceBackups)
makes any recent or older version of your org files easily
retrievable, so no information can be lost.

Yes, I have, but I'd like something a bit better.
I'm trying to write a little function using before-save-hook to compare
the current buffer to the saved version and output the result of
diffstat, asking the user whether they want to go ahead with the save or
view the full diff. Or has someone done something like this before?
I suppose one could do this with some kind of before-change- type
function if feeling particularly paranoid.

...Provided you know that you killed something you didn't intend to.
However, it's easy to kill a tree without noticing it had content.
Maybe we could augment org-kill-line with some optional facility that
checks that it doesn't encompass a collapsed section -- or less
intrusively, emits a message saying it's killed a collapsed section.
I'm having a hard time seeing how to code it though.

See diff-buffer-with-file.

Yes, that was the idea. I was going to hook a function into
before-save-hook which does pipe diff -u $1 $2 | diffstat and show the
result in some kind of minibuffer. Not sure how to set $1 and $2 (in
fact, I've never written any elisp at all). I don't suppose anyone could
whip up the code in a moment or two? ;-)

Re-bind keys like C-w et al in org-mode-hook?
Untested:
(defun org/wimpy-kill-setup ()
"Re-bind keys, that remove a significant amount of data."
(define-key org-mode-map [(control ?w)] 'kill-region-wimpy)
;; ...
)
(add-hook 'org-mode-hook 'org-/wimpy-kill-setup)

You're recreating what version control is for.
I have my org-files setup in a Bazaar repo, and if any changes were
made it auto-commits hourly via cron. I can also manually commit.
Prior to committing, I can press C-x v = to see a diff of what has
changes, and the Bazaar tools make it easy to step backward through
the history to see changes.
Version control is your backup and your protection against data loss.

I don't need all the functionality of version control, just a check
against the last saved version to make sure I haven't inadvertently
deleted too much.
I've used Hg and bzr in the past and they work fine but I don't think I
need them for this.
> Version control is your backup and your protection against data loss.
It's *a* form of backup. Another might be more appropriate.
Thanks for the input
