## Common Usage Patterns

### Keybinding Integration

These IPC commands are designed to be used with window manager keybindings.

**Example niri configuration:**
```kdl
binds {
    Mod+Space { spawn "qs" "-c" "dms" "ipc" "call" "spotlight" "toggle"; }
    Mod+V { spawn "qs" "-c" "dms" "ipc" "call" "clipboard" "toggle"; }
    Mod+P { spawn "qs" "-c" "dms" "ipc" "call" "notepad" "toggle"; }
    Mod+X { spawn "qs" "-c" "dms" "ipc" "call" "powermenu" "toggle"; }
    XF86AudioRaiseVolume { spawn "qs" "-c" "dms" "ipc" "call" "audio" "increment" "3"; }
    XF86MonBrightnessUp { spawn "qs" "-c" "dms" "ipc" "call" "brightness" "increment" "5" ""; }
}
```

**Example Hyprland configuration:**
```conf
bind = SUPER, Space, exec, qs -c dms ipc call spotlight toggle
bind = SUPER, V, exec, qs -c dms ipc call clipboard toggle
bind = SUPER, P, exec, qs -c dms ipc call notepad toggle
bind = SUPER, X, exec, qs -c dms ipc call powermenu toggle
bind = SUPER, slash, exec, qs -c dms ipc call hypr toggleBinds
bind = , XF86AudioRaiseVolume, exec, qs -c dms ipc call audio increment 3
bind = , XF86MonBrightnessUp, exec, qs -c dms ipc call brightness increment 5 ""
```

### Scripting and Automation

IPC commands can be used in scripts for automation:

```bash
#!/bin/bash
# Toggle night mode based on time of day
hour=$(date +%H)
if [ $hour -ge 20 ] || [ $hour -le 6 ]; then
    dms ipc call night enable
else
    dms ipc call night disable
fi
```

### Status Checking

Many commands provide status information useful for scripts:

```bash
# Check if screen is locked before performing action
if dms ipc call lock isLocked | grep -q "false"; then
    # Perform action only if unlocked
    dms ipc call notifications open
fi
```

## Return Values

Most IPC functions return string messages indicating:
- Success confirmation with current values
- Error messages if operation fails
- Status information for query functions
- Empty/void return for simple action functions

Functions that return void (like media controls) execute the action but don't provide feedback. Check the application state through other means if needed.
