If I start a new session in the background, and use send-keys to run
`display-message`, I seem to get incorrect values for #I, #W, and #P.
For example the following sample set of commands:
session_name="TEST"
# Window 0tmux new-session -d -s "$session_name" -n "Window_0"tmux
send-keys -t "$session_name":0 "tmux display-message -p '#S #I #W #P'"
Entertmux split-window -htmux send-keys -t "$session_name":0 "tmux
display-message -p '#S #I #W #P'" Enter
# Window 1tmux new-window -t "$session_name" -n "Window_1"tmux
send-keys -t "$session_name":1 "tmux display-message -p '#S #I #W #P'"
Entertmux split-window -htmux send-keys -t "$session_name":1 "tmux
display-message -p '#S #I #W #P'" Enter
# Attach the sesssiontmux -2 attach-session -t "$session_name"
produces the output:
Window 0 Left Pane: TEST 0 Window_0 0Window 0 Right Pane: TEST 0
Window_0 1Window 1 Left Pane: TEST 1 Window_1 0Window 1 Right Pane:
TEST 1 Window_1 1
when it should be instead giving this output:
Window 0 Left Pane: TEST 1 Window_1 1Window 0 Right Pane: TEST 1
Window_1 1Window 1 Left Pane: TEST 1 Window_1 1Window 1 Right Pane:
TEST 1 Window_1 1
It somehow looks like the commands are not executed until a client attaches
to the session. Not sure if this is the expected behavior. So I've filed a
bug for this as well.
