On `connect`, create a new tmux session and move the relevant window in

(For context--My team is new to tmux. Overmind has been a fantastic process management solution in conjunction with turborepo for us).

Use case:

• Connect to one overmind/tmux session per Mac OS Terminal tab

We'd like to be able to open multiple tabs in Terminal, and run overmind connect [service] once per tab, with a different service per tab. However, currently, when connecting to more than one service in this way, tmux treats it as the same session and essentially makes ALL tabs view the same window (tmux has a concept of one current/active window per session).

Is there a way to disable this behavior, or create a new session per overmind connect [service] call, and move the tmux window for that service into that session?

Ok, here's a solution:

I added the following to overmind.tmux.conf (the tmux config that we load via the -F switch, e.g. overmind start -F scripts/overmind.tmux.conf):

set-hook -g client-attached "run 'sess=\`tmux new -d -P -t \"#{session_name}\"\` && tmux switch-cli -t \"\${sess}#{window_index}\"'"

Whenever a new client attaches, this creates a new session within the same overmind session-group (a session-group shares all windows within all sessions), and switches to the same window_index as was current before creating the new session.

This is allows us to open a different "current window" in each new Terminal tab.
