Has anyone separated their system clipboard from their emacs clipboard? I've followed the advice in https://stackoverflow.com/questions/24196020/how-to-stop-emacs-from-contaminating-the-clipboard but it has not appeared to make a difference. Deleting anything still overwrites my system clipboard.

@jayzawrotny no, haven't had the need to separate system clipboard and Emacs kill ring. I don't understand why you would need to do this, sorry. In Spacemacs I use the paste transient state, so I can easily cycle through the kill ring history https://github.com/practicalli/spacemacs-config/blob/master/.spacemacs.d/init.el#L385 I don't do a lot editing outside of Emacs, so don't need to worry about what Emacs puts on the kills ring for other apps. If I want to paste something from the system clipboard, I expect it to be the last thing I put on the Emacs kill ring. On the fairly rare occasion I need to paste something into Emacs before deleting, well that is what I do. In Vim style editing it makes much more sense to do that, as they you can use d t to delete to what ever character is after the end of the text you no longer want. Sorry I can't be of more help.
