Pane.waitForCommand

Description#

Needs a shell that marks each command's end with OSC 133 (ESC ] 133 ; D ; status) from its prompt; tmux turns the mark into a pane-command-finished event. send types a command line once the wait is listening, so a command that ends at once is not missed. A shell's first prompt marks an end too, before any command ran, so a wait armed while the shell starts can resolve with 0. A shell without the marks never resolves this: give it a timeoutMs, whose WaitTimeoutError names the marks as the likely cause. A pane whose program has exited rejects with LibTmuxError . The mark carries a status alone; what the command printed is on the pane, for Pane.capture .

Requires tmux 3.8 or newer.
