When running inside SSH, Control-X runs a clipboard utility on the remote system. For pbcopy (and probably clip.exe too) this means that we write to the remote system's clipboard. This is usually not what the user wants (although it is consistent with fish_clipboard_paste). When X11 forwarding is used, xclip/xsel copy to the SSH client's clipboard, which is what most users want. When we don't have X11 forwarding, we need a different solution. Fortunately, modern terminal emulators implement the OSC 52 escape sequence for setting the clipboard of the terminal's system. Use it in fish_clipboard_copy. Tested in SSH and Docker containers on foot, iTerm2, kitty, tmux and xterm (this one requires "XTerm.vt100.allowWindowOps: true"). Should also work in GNU screen and Windows Terminal. On terminals that don't support OSC 52 (like Gnome Terminal or Konsole), it seems to do nothing. Since there does not seem to be a way to feature-probe OSC 52, let's just always do both (pbcopy and friends as well as OSC 52). In future, we should probably stop calling pbpaste and clip.exe, at least on remote systems. I think there is also an escape sequence to request pasting the system clipboard but that's less important and less popular, possibly due to security concerns. |
