adhoc emacs Elisp command to send emacs clipboard text to osx clipboard

Question

When you press 'y' (elfeed-search-yank) in an elfeed-search buffer, the selected entry's permalink url is copied to the emacs clipboard.

I don't have any automatic clipboard sync packages installed, and I don't intend to.

Is it possible to Meta-: Eval: and tell emacs to send whatever is in the emacs clipboard to the OS (MacOS) clipboard?

What I tried: browsed the source code for https://github.com/jkp/pbcopy.el/blob/master/pbcopy.el didn't see any interesting functions

NOTE: I'm using terminal emacs

Answer 1

You can call copy-to-x-clipboard from Meta-X or Eval:. No Emacs packages necessary. It relies on the pbcopy shell command, which is available in all macOS installations.

(defun copy-to-x-clipboard ()
  (interactive) 
  (switch-to-buffer (make-temp-name "scratch"))  
  (insert (current-kill 1))
  (shell-command-on-region (point-min) (point-max) "pbcopy")
  (kill-this-buffer))

Yes

M-: (call-process-region (car kill-ring) nil "pbcopy")

Answer 3

If you are running a GUI Emacs, it should copy automatically everything that goes into kill-ring to the system clipboard. Are you running emacs in a terminal?

To answer your question, the code to copy the latest kill-ring addition to system-kill ring is:

(kill-new (current-kill 1))
