How can I yank to local system keyboard in tmux?

[lukehsiao]

With #5027, it seems like we should be able to yank from helix running inside tmux on a remote system to the local clipboard, but this doesn't seem to be working for me.

Curious if anyone can spot what's wrong.

I'm running macOS locally, using mosh to connect to a remote machine. Without tmux, I can confirm that I can :clipboard-yank to my local clipboard without issue.

Within tmux, I get

Couldn't set system clipboard content: clipboard provider tmux failed

I have looked at the tmux wiki and followed the instructions to set up the clipboard.

❯ tmux -V
tmux 3.0a

❯ tmux show -s set-clipboard
set-clipboard on

❯ tmux info | grep Ms
 180: Ms: (string) \033]52;%p1%s;%p2%s\a

And I'm using wezterm, which has support for OSC-52.

Does anyone have any ideas of what I'm missing?

Bummer, it seems that it is mosh that is blocking me. mobile-shell/mosh#637

With SSH, it works fine, even within the tmux session.

For mosh users: this workaround worked for me: https://gist.github.com/yudai/95b20e3da66df1b066531997f982b57b
