instantwmctl

instantwmctl is the runtime control tool for instantWM. It talks to the running window manager over IPC, so you can inspect state, switch layouts, manage scratchpads, change monitor settings, and run configured actions without restarting the session.

Usage

instantwmctl [OPTIONS] <COMMAND>

Global options:

• -j, --json: print machine-readable JSON where supported
• --ignore-version-mismatches: skip the IPC protocol version check

instantwmctl action set_mode resize
instantwmctl action keyboard_layout us(intl)
