Constants

const TraceLevel = logrus.Level(uint32(logrus.DebugLevel + 1))

TraceLevel is the log level for tracing. Trace level is lower than debug level, and is usually used to trace detailed behavior of the program.

Variables

var (
	// G is an alias for GetLogger.
	//
	// We may want to define this locally to a package to get package tagged log
	// messages.
	G = GetLogger

	// L is an alias for the the standard logger.
	L = logrus.NewEntry(logrus.StandardLogger())
)

Functions

func GetLogger

func GetLogger(ctx context.Context) *logrus.Entry

GetLogger retrieves the current logger from the context. If no logger is available, the default logger is returned.

func ParseLevel

func ParseLevel(lvl string) (logrus.Level, error)

ParseLevel takes a string level and returns the Logrus log level constant. It supports trace level.

func Trace

func Trace(e *logrus.Entry, args ...interface{})

Trace logs a message at level Trace with the log entry passed-in.

func Tracef

func Tracef(e *logrus.Entry, format string, args ...interface{})

Tracef logs a message at level Trace with the log entry passed-in.

func WithLogger

func WithLogger(ctx context.Context, logger *logrus.Entry) context.Context

WithLogger returns a new context with the provided logger. Use in combination with logger.WithField(s) for great effect.
