remain-on-exit not working

Post by Iain Morgan
Greetings,
With tmux 0.8, I don't seem to be able to get the remain-on-exit
functionality working. I've tried both 'set -g set-remain-on-exit on'
and 'setw -g remain-on-exit.' In both cases, the window disappears when
I exit. The option gets set but doesn't seem to have any affect.
Is this a known issue?

I think the correct config option would be:

set-option -g set-remain-on-exit

(man tmux)

set-option -g set-remain-on-exit

^^ on

of course turning it on would be even more desirable :)

Hmm. It should work for windows too since you can't have a window without any
panes... I'll have to check see if everything is working as expected.

A message might be nice, I'll add to todo list.

set-option -g set-remain-on-exit

After some experimentation last night, I discovered that remain-on-exit
works for panes rather than for windows. Also, unlike screen's 'zombie'
feature it does not print a message indicating when the process exited.
That information can be very useful at times.

Can you please try this diff? It is against OpenBSD -current but should apply
to tmux CVS HEAD as well, if not let me know.

This makes remain-on-exit apply to all panes including if there is only one
left in the window (I know there is no respawn-pane but straightening that kind
of thing out is for later problem as panes become more developed).

Hi,

i applied the patch to the current code from CVS and built tmux.
Unfortunately, it seems to have broken tmux. I get back an unresponsive
shell prompt after running 'tmux new.'

The set-remain-on-exit session flag will set the remain-on-exit flag for every
new window created in that session.

remain-on-exit should work but it appears it currently doesn't, probably due to
the pane changes I'll look into it sometime soon.
