You can use the session environment to store the pane id in a per-window
variable, e.g. like this:
store_tvim_pane()
{
CURWIN=$(tmux list-panes -F "#{window_index}" | head -1)
tmux set-environment "TVIM_PANE_ID_${CURWIN}" $1
}
get_tvim_pane()
{
CURWIN=$(tmux list-panes -F "#{window_index}" | head -1)
tmux show-environment | grep "TVIM_PANE_ID_${CURWIN}"
}
Note: the window_index format requires tmux 1.6. In the upcoming tmux 1.7,
show-environment can even query a single variable at a time, avoiding the
use of grep.
