fzf-tmux: hitting enter after `ctrl+T`/`alt+C` hangs tmux

[krshrimali]

• [x] I have read through the manual page (man fzf)
• [x] I have the latest version of fzf
• [x] I have searched through the existing issues

Info

• OS
  • [x] Linux
  • [ ] Mac OS X
  • [ ] Windows
  • [ ] Etc.
• Shell
  • [ ] bash
  • [x] zsh
  • [ ] fish

Problem / Steps to reproduce

1. Install fzf, set export FZF_TMUX=1 in your shell config.
2. Open terminal, launch tmux.
3. Press alt+C
4. Select anything random, hit enter.
5. No key-press works after it, it goes back to the terminal, but nothing works after that.

I'm aware that there are run-shell -b solutions, but this is separate (I assume).

Versions:

➜  ~ fzf-tmux --version
fzf-tmux (with fzf 0.32.1 (19f9bbc))
➜  ~ fzf --version
0.32.1 (19f9bbc)

Found this issue to be related with a couple of changes in tmux I made to help fix: https://github.com/neovim/neovim/issues/18667. The changes were: https://github.com/tiagovla/tmux/commit/f4a851c9c1aca136ee85169ee9e52dc9e5576ac3

I understand that it might not be directly related to fzf, but if anyone has any knowledge, does anyone know of a fix for this? I'm happy to close it in a couple of days though, since it's not a fzf bug! Thank you!

I found a similar issue today with Ctrl+R inside tmux with zsh. The easy workaround is to just not use the tmux integration, but I also can't find out why it's happening.

If it's indeed the same thing as I witnessed, switching fzf-tmux to popup mode (-p command-line switch) helped.

tmux 3.4?

See https://github.com/junegunn/fzf/issues/3635

If you can't use the latest fzf-tmux with the patch for some reason, you can use popup mode instead as suggested above.

export FZF_TMUX_OPTS='-p 100%,40% -y P'

Amazing yeah spot on that's exactly my issue and setting those options fixed it. I'll wait for the next release and then upgrade. Thank you!
