You've got some long running tasks, and you're trying to stay productive and
knock tasks off that board, but you keep finding that your processes finish and
you stay on other tasks for longer than you should. You were in the flow and
just did not check back in on it. With
display-message you can send yourself
a notification when that long running task is complete.
Here is a snippet of
display-message from the tmux man page. I rarely need
to do anything other than just display message, but there are other flags for
display-message [-aINpv] [-c target-client] [-d delay] [-t target-pane] [message] (alias: display) Display a message. If -p is given, the output is printed to stdout, otherwise it is displayed in the target-client status line for up to delay milliseconds. If delay is not given, the message-time option is used; a delay of zero waits for a key press. ‘N’ ignores key presses and closes only after the delay expires. The format of message is described in the FORMATS section; information is taken from target-pane if -t is given, otherwise the active pane. -v prints verbose logging as the format is parsed and -a lists the format variables and their values. -I forwards any input read from stdin to the empty pane given by target-pane.
display-message we can do things like setup notifications that will work
cmatrix -t 5 && tmux display-message done
Without setting the target-pane
display-message defaults to the active pane.
This is a very handy feature that allows us to switch windows, or sessions and
still recieve the message.
