Hi all:
I have recently upgraded to Emacs 29.1, but I do not know whether I am hitting a new issue or regression, as I have always had Clipboard problems. Today I am trying to understand and fix one specific issue with gui-set-selection.
I have compiled Emacs myself on Ubuntu MATE 22.04.3.
I want Emacs' clipboard to behave like Microsoft Windows, GEdit, Pluma, usw., so I have set these variables:
(setq select-enable-clipboard t)
(setq select-active-regions nil)
Say I select and copy a piece of text in Emacs. Then I can paste the text both in Emacs and in an external editor like GEdit or Pluma. So far so good.
I have written an Emacs routine which converts something and places it in the X clipboard like this:
(gui-set-selection 'CLIPBOARD result)
Say I type, select and copy the piece of text "manual-text" in Emacs, and I then run my Emacs routine, which ends up placing in the clipboard the piece of text "from-gui-set-selection".
If I now paste inside Emacs, I get "manual-text". However, if I paste inside GEdit, Pluma, etc., I get "from-gui-set-selection".
That is, gui-set-selection is not updating Emacs' internal clipboard. Or perhaps Emacs does not realise that the X clipboard has changed when it was Emacs itself the one which just changed it.
If I now select a piece of text in GEdit, Pluma, etc. and copy it, then I can paste it into Emacs without trouble. Well, mostly, but that is an issue for another day.
I tried calling gui-set-selection again in my Emacs routine, but this time passing nil, 'PRIMARY or 'SECONDARY, to no avail. I must admit that I do not really understand how Emacs handles the clipboard.
Can somebody help?
Thanks in advance,
rdiez

This is intentional; if you want it to, save the text to the kill ring
instead.
