tmux + mosh OSC 52 clipboard paste hack

Problem

Now tmux, mosh and iTerm2 support the OSC 52 sequence that enables clipboard sharing. However, there is a trap that prevents them from working together.

Mosh accepts OSC 52 sequences with the c; option. However, tmux doesn't send that option when it emits OSC 52 sequences, which means you cannot use tmux and mosh together with the default configuration.

Workaround

You can override the OSC 52 sequence generated by tmux by adding the following line to your tmux.conf.

set-option -ag terminal-overrides ",xterm-256color:Ms=\\E]52;c;%p2%s\\7"

Instead of using the default Ms sequence Ms=\\E]52;%p1%s;%p2%s\\7", whose %p1%s; is the option part, this configuration forces use c; as the option value.

Note that xterm-256color must be replaced with your $TERM value.

PR for mosh that avoids the need for custom tmux settings: mobile-shell/mosh#1054

@yudai @tylerhoran @agriffis @gwicke Do you know what the minimum mosh version needed for this is? It's not working for me and I wish it did, I would love to get this working without having to build a custom mosh right now (but thanks for your work @gwicke!)

@dasizeman There isn't a release of mosh with truecolor support. You need unreleased trunk. mobile-shell/mosh#974

If you're running Fedora, you can use my COPR https://copr.fedorainfracloud.org/coprs/agriffis/mosh-nightly/

Alternative PR that claims to improve on the one @gwicke suggested: mobile-shell/mosh#1104

But actually, this seems to be a bug in tmux that is already fixed on the master branch (and thus hopefully in the next release): tmux/tmux#3192

not sure if the clipboard option was removed or not but running

tmux show-options -g clipboard

yields

invalid option: clipboard

You need to do: tmux show-options -g set-clipboard

warning that this seems to break osc52 with tmux 3.4 which has added some additional OSC features/support

set-option -ag terminal-overrides ",xterm-256color:Ms=\\E]52;c;%p1%s%p2%s\\7" is ok in tmux 3.4. But I dont find any description about %p1%s , It seems that no content is generated by default.

Updated on August 24th
According to tmux#4081, set-option -ag terminal-overrides ",xterm-256color:Ms=\\E]52;c%p1%.0s;%p2%s\\7" should be a better choice. @syu-id

Thanks @popjdh! This works for both tmux 3.4 and 3.3a on my machines.
