Variables

	ErrInvalidLogLevel = errors.New("invalid log level")
	ErrOpenLogFile     = errors.New("failed to open log file")
)

Functions

func Init

func Init(config Config) error

Init validates config and initializes the default slog logger.

func Levels

func Levels() []string

Levels generates a sorted list of valid log levels from the logLevelMap.

func ParseLogLevel

func ParseLogLevel(level string) (slog.Level, error)

ParseLogLevel converts a log level string to its corresponding slog.Level. An empty string returns the default value of slog.Level with no error. If the level string is invalid, it returns an error.

Types

type Config

type Config struct {
	Filename  string // Path to the log file. Uses stderr if empty.
	Type      string // Log format: 'json' or 'text'.
	Level     string // Log level as a string.
	AddSource bool   // If true, includes source code position in logs.
}

Config defines the configuration options for logging.
