I use the brilliant answer from my previous question to copy selected regions of text from Emacs onto my system pasteboard (i.e. the OSX clipboard).

But some functions (e.g. gist-buffer) push output (e.g. a URL) onto the Emacs kill ring, and I'd like to be able to access that text from other OSX apps. (Without having to do yank, highlight region, then pbcopy like I currently do.)

So: How can I push text directly from the Emacs kill-ring to the OSX pasteboard?

The function x-select-text can be used to do this:

Select TEXT, a string, according to the window system.

On X, if `x-select-enable-clipboard' is non-nil, copy TEXT to the
clipboard.  If `x-select-enable-primary' is non-nil, put TEXT in
the primary selection.

So we need to setx-select-enable-clipboard to a non-nil value (e.g., t). On Linux machines, it's set to t by default, so you may or may not need to do this.

(setq x-select-enable-clipboard t)

(defun copy-current-kill-to-clipboard ()
  (interactive)
  (x-select-text (current-kill 0)))

I don't have an OSX machine to test on -- only Linux --, but this should all work the same on OSX.

  • This won't work for me, since I have interprogram-cut-function and interprogram-paste-function set to nil. So I need to push the kill ring to the pasteboard manually. – incandescentman Jul 29 '15 at 16:22
  • I updated the answer to include code to do that. – zck Jul 29 '15 at 16:48

    PSA: x-select-enable-clipboard var name is getting deprecated in emacs 25+ and is being replaced with select-enable-clipboard. Similarly x-select-enable-primary -> select-enable-primary. – Kaushal Modi Jul 31 '15 at 14:55
  • So what's a better way to code it? – incandescentman Jul 31 '15 at 17:06
