Functions

func Exists

func Exists(key string) bool

Exists checks if a configuration key is present: - Case-insensitive check - Returns false for invalid keys - Uses simple string contains check

func Get

func Get(key string) string

Get retrieves a configuration value: - Case-insensitive key lookup (converts to uppercase) - Returns empty string if key not found - Validates key before lookup

func Set

func Set(key, value string) error

Set writes or updates a configuration value: - Validates key (letters only) and value - Creates new entry or updates existing one - Automatically converts keys to uppercase Returns error if validation or write fails
