FocusGained works with Terminal.app (and tmux)

bruno- commented 9 years ago

Hi, it seems I managed to get FocusGained work by using this plugin and tmux. Steps for this are below and I'm still a bit fuzzy why\ this works.

Tools:

OS X 10.10.1, Terminal.app (iTerm will work just fine, but we already knew it works)
tmux 1.9a
terminal vim (neovim works too)

How to enable FocusGained for terminal vim with the above tools:

make sure tmux has the focus-events option on: tmux set -g focus-events on
install the vitality.vim plugin
set this option: let g:vitality_always_assume_iterm = 1

That's it! FocusGained should now work. I've tested it with vim by setting the following autocommand:

au FocusGained * echom 'focus gained!'

A couple observations:

FocusLost does not work for some reason
this does not work outside tmux (plain Terminal.app + vim)

If this plugin is still maintained, do you think we could add these instructions somewhere (wiki maybe) so people know this is possible? Also, how about enabling the plugin when vim is running inside tmux so that let g:vitality_always_assume_iterm = 1 is not required?

Thanks,

Confirmed correct actions (FocusGain, FocusLost) on Terminal.app, OS 10.10

When you changed the .tmux.conf, make sure to reload or kill the tmux server. This caused me an hour to debug.

Unlike @bruno-, FocusLost also works seamlessly.

@bruno- @chrischoy My experience has been that FocusLost pretty much works, except that no matter what I tried I could not make it properly run echo or echom (while FocusGained had no problems with it). It is bizarre, but I am not about to lose sleep over it.

Hey, it's good to hear that FocusLost works for you guys.. btw. how were you able to verify it works if echo or echom doesn't work?

I just tried and this au FocusLost * echom 'focus lost!' doesn't work for me too.
