TMUX how-to?

[vorburger]

https://github.com/jethrokuan/fzf#alternatives lacks Tmux support

https://github.com/PatrickF1/fzf.fish/wiki/Prior-Art chose not to implement Tmux support, because users can easily add support externally themselves

How do you get Ctrl-F etc. working inside TMUX? 😺

https://github.com/PatrickF1/fzf.fish/wiki/Troubleshooting (or https://github.com/PatrickF1/fzf.fish/wiki/FAQ) could document it.

It actually appears to work just fine out of the box under TMUX. I'm now just curious what was meant by add support externally themselves.

Hi @vorburger! Welcome!

what was meant by add support externally themselves.

So my understanding is that Tmux users often want to open fzf in a new pane (why? not sure). And to do that, they need to call a wrapper. It's documented here: https://github.com/junegunn/fzf#fzf-tmux-script. Seems like a popular thing. Jethrokuan/fzf implements it: https://github.com/jethrokuan/fzf/blob/8ee7cf502637a9dd7d0cd96ead67c631a25e49d9/functions/__fzfcmd.fish
This user forked my repo and changed it: insidexino@473bf33

TBH I'm not even a Tmux user and I've only used it briefly (and decided it wasn't for me). However, I suspect that we can accomplish the same thing without changing the source code. All you need to do is put in your config.fish something like this

function fzf --wraps=fzf --description="Use fzf-tmux if in tmux session"
  if set --query TMUX
    fzf-tmux $argv
  else
    command fzf $argv
end

Does it work? I dunno...would you like to help me test it? That way I can document it in the FAQ as you suggested.
I've added it to the Wiki for now.
