IPC

tarmac exposes a full IPC (inter-process communication) interface over a Unix domain socket. External tools, scripts, and the tarmacctl CLI can send commands and receive events.

Overview

The IPC system provides:

• Command execution — focus, swap, resize, workspace management, etc.
• State queries — get windows, workspaces, monitors, layout trees
• Event subscription — real-time stream of workspace changes, window focus, etc.

Sections

• Socket & Protocol — socket location, JSON wire format, permissions
• tarmacctl — the CLI control tool
• Commands — complete command reference
• Events & Subscribe — subscribing to real-time events
