bug#74833: 31.0.50; Copy to OS clipboard doesn't work in macOS Terminal.app with xterm-mouse-mode enabled

[Filipp Gunbin]

macOS, Terminal.app, xterm-mouse-mode enabled
emacs -nw -Q
Select something with mouse, press Command-c
Try to paste into another program - text is not in the clipboard

Perhaps this is not new, I just tried xterm-mouse-mode for the first
time, given that it's now the default in master.

Trying different combinations of select-enable-clipboard and
select-enable-primary did not help (that variables are all I know in
this area).

Thanks.

You need something like https://elpa.gnu.org/packages/xclip.html to assist
connecting macOS terminal Emacs to the system pasteboard/clipboard.

Thanks, BTW paste with Command-V works, it's just copy that doesn't
work.  Probably I'll disable xterm-mouse-mode anyway, but it would be
nice to have this resolved in Emacs.

I think that's because Terminal.app is providing paste, not Emacs. If you
use Emacs commands to put text into the kill-ring, it has to make it from
there into the pasteboard/clipboard and that's what xclip does for you.

Does the macOS Terminal.app support the xterm mouse protocol?

It supports a subset of mouse behavior via this user setting:

That doesn't tell enough.  xterm.el and xterm-mouse assume full
support for the xterm protocols, so partial support could well explain
why things don't work.

In general, I don't recommend turn on xterm features on terminals
other than xterm, unless they are faithful emulations of xterm.

Yes it does.

The clipboard problem is something unrelated. Terminal applications can
access the macOS clipboard via command line utilities pbcopy and
pbpaste. I'm using the package xclip for that, which is very simple to
use

  ;; Clipboard support in terminal Emacs using pbcopy/pbpaste.
  (use-package xclip :straight t
    :if (not (display-graphic-p))
    :config (xclip-mode 1))

Command-C, Command-V in Terminal.app are used by Terminal.app itself and
not by applications running in the terminal emulator. For example, to
copy shell output or paste something as shell input.

I don't think Terminal.app allows altering Command-V etc. so that Emacs
could use them. Other terminal emulators like iTerm allow doing that.

In summary, this is not a bug.

There is, for some reason, a checkbox in Terminal.app Settings dialog
with which one can make Terminal.app not send xterm mouse escape
sequences. If it's off when Emacs runs it doesn't get informed about
mouse clicks and so on. So nothing happens.

I have xterm-mouse-mode enabled when in tty mode on macOS and it does work
for clicking/selecting but this is independent of integrating the kill ring
with the pasteboard. I am unaware of how to test the completeness of the
xterm mouse protocol support, however.
