"""Central configuration and system setup manager for the Wire-Py application.
|
|
|
|
This class serves as a singleton-like container for all global configuration data,
|
|
including paths, UI settings, localization, versioning, and system-specific resources.
|
|
It ensures that required directories, files, and services are created and configured
|
|
before the application starts. Additionally, it provides tools for managing translations,
|
|
default settings, and autostart functionality to maintain a consistent user experience.
|
|
|
|
Key Responsibilities:
|
|
- Centralizes all configuration values (paths, UI preferences, localization).
|
|
- Ensures required directories and files exist on startup.
|
|
- Handles translation setup via `gettext` for multilingual support.
|
|
- Manages default settings file generation.
|
|
- Configures autostart services using systemd for user-specific launch behavior.
|
|
|
|
This class is used globally across the application to access configuration data
|
|
consistently and perform system-level setup tasks.
