Devices
Devices are critical in enhancing the operation of Violet. These physical components, which range from cameras and microphones to storage disks and network adapters, are required for a variety of tasks and interactions. Violet uses Device Integration Files (DIFs) to provide a uniform interface for easy device integration in order to properly manage various devices.
Connecting a New Device
Violet creates a Device Integration File (DIF) in the /dev directory when you connect a
new device to your computer. DIF placement and configuration may differ based on the
device type. A hard drive, for example, may have a DIF path like /dev/sst/b0b4. These
filenames are unique and random, with the format [a-z][0-9][a-z][0-9]
(lowercase, digit, lowercase again, and then another digit).
Interacting With a Device
The sys::hw service is used to interact with devices by applications and system services.
For uncategorized devices (in /dev/etc), a popup is shown to the user, to indicate
the connected device is not recognized.
Device Integration file Persistence
When you disconnect a device, the Device Integration File (DIF) linked with it is not
instantly deleted. When a process tries to interact with the DIF; the sys::hw service
reports that the device is not currently connected. This enables apps to save the
device's location and association for future usage.
When the device is reconnected, it is linked with the same DIF, guaranteeing consistency and keeping the device's reference in the system.
Custom Device Integration File Name
Violet allows Violetians to define Device Integration File (DIF) Names, adding a customized touch to the device management experience. Violetians may utilize this functionality to provide DIFs distinctive names, ensuring easy connection with apps.
When a DIF is given a custom name, Violet produces a new DIF file and correlates it with the original, retaining compatibility with apps that rely on the original DIF. This approach enables users to get benefits of customizable naming conventions without sacrificing functionality. The original DIF and the modified DIF both provide the same capability and features to the underlying device.
Custom DIF names must be more than four characters long to provide clarity and system consistency. The simple rule identifies custom DIFs from those created automatically, delivering a consistent experience throughout the operating system.
Device Management Interface
Violet features a device management interface available through the Settings application to simplify device management and streamline user interactions. Violetians can easily setup, debug and update drivers, which gives them instant access to all connected devices.
