I'm using Vim with tmux and I wanted to know if there was a signal or something to 'deactivate' the vim window (like when you switch between vim windows) but also when you switch between Vim and Tmux. I'm using vim-tmux-navigator and tried to modify it to have this effect.

    Welcome to Vi and Vim! Can you clarify your terms? What does « deactivate » mean? And when you say « window » (twice), are you referring to vim split windows, tmux windows (sub-parts of tmux sessions, similar to vim tabpages), or tmux panes (sub-parts of tmux windows, similar to vim split windows)? It’s also not precisely clear what you mean by signal, but I suppose that’s because that’s the question.

  • I tried to use 'airline_focuslost_inactive' parameter to 1 but it doesn't do anything, also tried looking on the github page and people have other problems with it

  • @ndfg201 you did not specify what exactly you want (or I did not understand it). But I know of no problems with the given airline parameters. So please be precise (and open an new issue if you think you have found a bug) Commented Sep 17, 2020 at 14:13

vim-tmux-focus-events will send FocusGained and FocusLost events to vim.

This will enable Vim to reload a file that has changed on disk once you switch back to the Vim window.

I don't know airline but if it uses the same events it will work there as well.


I found something that work in tmux.conf :

set -g focus-events on

Nothing more
