disable region after running a command on it

disable region after running a command on it

[Luca Ferrari]

Hi all,
is there a way to disable a region every time a command has been run
on it? For example, I mark a region, M-x eval-region and I would like
that the region selection disappear.

Thanks,
Luca

Add deactivate-mark to your post-command-hook?

(defun maybe-deactivate-mark ()
   (if (memq this-command
 	    '(eval-region
 	      ;; other commands after which you want to deactivate mark
 	      ))
       (deactivate-mark)))

(add-hook 'post-command-hook #'maybe-deactivate-mark)

What' you're asking is the normal behavior, usually.  I see indeed that
`eval-region` doesn't follow this principle, but I can't see any good
reason for that, so maybe a bug report is the best way to fix
the problem.

That was going to be my answer: this is the normal
behavior of the command loop.  Generally, if you 
_don't_ want the region deactivated after each
command you need to do something, such as call
`deactivate-mark' or reset var `deactivate-mark'
to nil.
