interpolate #{pane_tty} into copy-pipe

[Suraj N. Kurapati]

Hello,

I'm trying to use copy-pipe with my yank[1] script to copy the
selection to my system clipboard via the OSC 52 escape sequence.
But in order for this to work, the escape sequence needs to be
written *directly* to the terminal device that has tmux attached.

I tried the following copy-mode key bindings, but nothing worked:

bind-key -t vi-copy y copy-pipe 'yank'
bind-key -t vi-copy y copy-pipe 'yank > /dev/tty'
bind-key -t vi-copy y copy-pipe 'yank > #{pane_tty}'
bind-key -t vi-copy y copy-pipe 'tmux run-shell "yank > #{pane_tty}"'

In contrast, writing to #{pane_tty} works in normal key bindings:

# transfer most-recently copied text to attached terminal with yank:
bind-key -n M-y run-shell 'tmux save-buffer - | yank > #{pane_tty}'

# transfer previously copied text (chosen from a menu) to attached terminal:
bind-key -n M-Y choose-buffer 'run-shell "tmux save-buffer -b \"%%\" - | yank > #{pane_tty}"'

How can I interpolate the correct #{pane_tty} value into copy-pipe?

Thanks for your consideration.

Try this please (although if your terminal supports OSC 52 you could
just put Ms in terminal-overrides and turn on set-clipboard).

Thanks! The following configuration now works due to this patch:

bind-key -t vi-copy y copy-pipe 'yank > #{pane_tty}'

I would request you to promote this patch into the tmux codebase.

Thanks for the tip, that's very handy. It doesn't handle my needs
though because it copies to the primary selection rather than the
clipboard selection, which is troublesome for me because hitting
mouse3 (middle click) on a laptop touchpad is largely hit-or-miss.

Thanks for your consideration.

On most host Terminals the target of clipboard operation is configurable, see eg man xterm

You can configure xterm so OSC 52 defaults to clipboard, or set Ms so
that tmux sends it to clipboard. Probably something like Ms=\E]52;c;%p2%s\007

Thanks for the tip! I was able to use your suggestion successfully:

set-option -ga terminal-overrides ',xterm*:Ms=\E]52;c;%p2%s\007'

However, I would still request this patch to be promoted into the
tmux codebase because I sometimes use non-xterm terminals (hterm).

Patch is in openbsd now will be in SF next time it's synced up

Wonderful! Thanks for all of your help. Long live tmux! :)
