Overview

Public programmatic API. Composes the focused helpers — nothing here should contain real business logic, only wiring and delegation.

Constant Summary collapse

DEFAULT_INTERRUPT_DELAY =

Delay (seconds) between the two Ctrl-C presses during a restart, and between Ctrl-C and sending the new command. In production 1s is enough to let the pane's shell redraw its prompt; tests shorten this to avoid paying multi-second waits for a purely cosmetic settle.

#run_command(window_name, command_name) ⇒ Object

Run a window's named command (mxup <config> <window>:<name>) in a copy of that window's environment, streaming its output to the calling shell and exiting with its return code. Does not touch the live tmux pane, so it works whether or not the session is up.
