Probably useless here in Wayland spheres – certainly when not talking about middle-click select/paste. But as to historic X behavior OP’s description would be expected which is what I triggered on. Now admittedly that ICCCM document is very old and crusty, and perhaps things have in some environments/circumstances changed in practice even under X11 – and once again no idea whatsoever about Wayland. select something in Firefox it’s available for middle-click paste into a terminal but not after closing Firefox that previously selected text would not seem to have made it onto any sort of clipboard indeed. Should owner cease to exist it would therefore then seem that certainly requestor is SoL and my Manjaro XFCE install would apparently agree: if you e.g. I.e., requestor (the pasted-into window) can even request a format conversion from owner, and in any case, it’s only at the time of the request, the middle-click paste, that the owner puts the selected data in a window property from where to then be collected. Send the requestor an event to let it know the property is available.Place this data in the named property on the named window.Convert the contents of the selection to the requested data type.If the selection is currently owned, the owner receives an event and is expected to do the following: All items will be restored when application is started next time. Copying text or image to clipboard will create new item in the list. The list with clipboard history is accessible by clicking on system tray icon or running copyq toggle. A requestor wishing to obtain the value of a selection provides the following: To start the application double-click the program icon or run copyq. The owner has the data representing the value of its selection, and the requestor receives it. Selections communicate between an owner and a requestor. ![]() Looked into it some time ago when implementing an X11 “selection clear” utility (in a privacy context). I am unsure why that does not seem to be working for you on Sway, maybe the clipboard managers you tried do not support Wayland?Īnd at least on X11, the middle-click paste buffer (PRIMARY) is not all that different from the regular clipboard (CLIPBOARD) technically.Īn as you say clipboard manager could do many things but the idea as to the normal primary selection is that no such thing as a clipboard let alone manager of such exists, historically and/or by default at least. In any case, a clipboard manager should retain at least the explicitly copied clipboard after the application exits. (In fact, PRIMARY is normally invalid as soon as you unselect the text, but the clipboard manager can retain it, and if it does that, it will usually also keep retaining it after the application exists.) At least the KDE Plasma clipboard managers, both the clipboard plasmoid and the legacy Klipper application, can do that. (On Wayland, it is handled by a different protocol extension though.) Clipboard managers can retain both after the application has exited. I do not know whether Sway does.)Īnd at least on X11, the middle-click paste buffer (PRIMARY) is not all that different from the regular clipboard (CLIPBOARD) technically. ![]() (Qt and GTK on the toolkit side, and KWin and GNOME Shell (mutter) on the compositor side definitely support it. Using a decent default command for your particular OS via cat foo.Middle-click paste is also supported on Wayland these days, though not all applications/toolkits and compositors might support the extension. This is easier in principle in fish, which alias pbcopy "xclip -selection clipboard"Īlias pbpaste "xclip -out -selection clipboard" I can never remember this half way through a pipe when I need it, so I put this in my bash profile and pretend I am on macOS. Xclip -out -selection clipboard > file.txt ![]() Something about my “middle mouse button” which is something I have on relatively few of the mismatched menagerie of mice that my computers use.Īnyway, the argument I need to actually use to work with the clipboard content for normal apps accessed using the copy paste conventions of the non-X11 world and laptops without a “middle button”, is There is some whole parallel copy-paste system that I do no care about and which is not in my muscle memory and I will therefore never use. Or somewhere else I do not know how to retrieve it from because I am not 7ee+ hack0rz. The command is xclip, which per default copies your data into pneumatic pipes, Easy …and yet! Needlessly doesn’t do what you expect!
