Not enough values to unpack in tmux parse.py

[EmilSodergren]

I get this error when updating COQ. I run it in neovim: v0.8.0-dev-1185-geb4844b5e-dirty and also tmux: next-3.4

ValueError: not enough values to unpack (expected 7, got 1)

When reverting to the dev branch i get the same error but it then expects 9 values to unpack.

A more controlled update of my environment gives that this is due to recent changes in the tmux repository. The changes that seems to cause this are show in tmuxdiff

I am also getting this behavior on tmux next-3.4. Downgrading to tmux 3.3 fixes the problem

[shebpamm]

Specifically, looks like the current _SEP symbol (\x1f) is handled differently in tmux 3.4 and instead of returning the proper symbol a (possibly escaped?) \037 symbol is returned. This command returns different output when running tmux instance is 3.3a or 3.4-next:

printf "#{session_id}\x1f#{pane_id}\x1f#{pane_title}" | xargs -I{} tmux list-panes -F {}

I have tmux 3.3a in both mac and linux machines and neovim v0.9.1 and I get this error only in linux, it works perfectly fine in mac (macOS Ventura 13.4).

[vegerot]

interesting. I only get this error on macOS

[vvaltchev]

I'm having exactly the same problem after upgrading tmux to next-3.4.

This is happening to me in 3.3 as well...
