Copy-paste from Remote to Local (need more precisions)

[faxotherapy]

Hello,
thanks a lot for sharing your tmux.conf. However, I need some more precisions with regard to yank. I'd like to select text and copy it from remote session and paste it into my local session. As I prefer keeping my own tmux.conf file I only grabbed the necessary part off your conf. file. So, I have inserted in my local tmux.conf the following:

yank="~/.tmux/yank.sh"

# Copy selected text
bind -T copy-mode-vi Enter send-keys -X copy-pipe-and-cancel "$yank"
bind -T copy-mode-vi y send-keys -X copy-pipe-and-cancel "$yank"
bind -T copy-mode-vi Y send-keys -X copy-line \;\
    run "tmux save-buffer - | $yank"
bind-key -T copy-mode-vi D send-keys -X copy-end-of-line \;\
    run "tmux save-buffer - | $yank"
bind -T copy-mode-vi C-j send-keys -X copy-pipe-and-cancel "$yank"
bind-key -T copy-mode-vi A send-keys -X append-selection-and-cancel \;\
    run "tmux save-buffer - | $yank"

# Copy selection on drag end event, but do not cancel copy mode and do not clear selection
# clear select on subsequence mouse click
bind -T copy-mode-vi MouseDragEnd1Pane \
    send-keys -X copy-pipe "$yank"
bind -T copy-mode-vi MouseDown1Pane select-pane \;\
   send-keys -X clear-selection

I've got several questions:

1. Do I need to copy yank.sh on remote machine as well?
2. Do I need to insert the above extracted content to my remote tmux.conf as well?
3. Is set -g @copy_backend_remote_tunnel_port 11988 still necessary (coming from tmux.remote.conf)? If so, do I have to copy it onto the remote machine as well?

Thanks for your time.

Notes: as a Mac user, I have:

1. Enabled the plist file for listening on port 9999
2. Activated remoteforward=9997 localhost:9999 (SSH)
3. Of couse, I grabbed both files yank.sh and tmux.remote.conf, but don't know whether they must be copied on both machines or not.
4. I must mention that I have tmux-yank plug-in installed on both machines. Just in case…

I tested the following on remote session and it works:

date | nc localhost 9997

What I'd like to do instead is selecting text on remote, press y key, and the selected content jumps into my local clipboard.

Just found something working nice and easy. Let's recap the first boring steps mentioned above:

1. Setup your network listener on your local machine (MacOS, Linux). Use, for example, port 9999 as listen port.
2. SSH to your remote machine with remoteforward=9997 localhost:9999 set in your SSH config file. If no config file, then: ssh -R 9997:localhost:9999 …@…

Now, the fun part…

3. Play around with tmux-yank and add the plug-in on both your local and remote machines.
4. Insert set -g @override_copy_command 'nc localhost 9997' in your remote tmux.conf file and reload.

Enjoy!

Note: also works with nested tmux sessions. No need to press F12 to turn outer session's root keybindings off.
