Functions

func DPanic

func DPanic(args ...interface{})

DPanic uses fmt.Sprint to construct and log a message. In development, the logger then panics. (See DPanicLevel for details.)

func DPanicf

func DPanicf(template string, args ...interface{})

DPanicf uses fmt.Sprintf to log a templated message. In development, the logger then panics. (See DPanicLevel for details.)

func DPanicw

func DPanicw(msg string, keysAndValues ...interface{})

DPanicw logs a message with some additional context. In development, the logger then panics. (See DPanicLevel for details.) The variadic key-value pairs are treated as they are in With.

func Debug

func Debug(args ...interface{})

Debug uses fmt.Sprint to construct and log a message.

func Debugf

func Debugf(template string, args ...interface{})

Debugf uses fmt.Sprintf to log a templated message.

func Debugw

func Debugw(msg string, keysAndValues ...interface{})

Debugw logs a message with some additional context. The variadic key-value pairs are treated as they are in With.

When debug-level logging is disabled, this is much faster than

s.With(keysAndValues).Debug(msg)

func Error

func Error(args ...interface{})

Error uses fmt.Sprint to construct and log a message.

func Errorf

func Errorf(template string, args ...interface{})

Errorf uses fmt.Sprintf to log a templated message.

func Errorw

func Errorw(msg string, keysAndValues ...interface{})

Errorw logs a message with some additional context. The variadic key-value pairs are treated as they are in With.

func Fatal

func Fatal(args ...interface{})

Fatal uses fmt.Sprint to construct and log a message, then calls os.Exit.

func Fatalf

func Fatalf(template string, args ...interface{})

Fatalf uses fmt.Sprintf to log a templated message, then calls os.Exit.

func Fatalw

func Fatalw(msg string, keysAndValues ...interface{})

Fatalw logs a message with some additional context, then calls os.Exit. The variadic key-value pairs are treated as they are in With.

func Info

func Info(args ...interface{})

Info uses fmt.Sprint to construct and log a message.

func Infof

func Infof(template string, args ...interface{})

Infof uses fmt.Sprintf to log a templated message.

func Infow

func Infow(msg string, keysAndValues ...interface{})

Infow logs a message with some additional context. The variadic key-value pairs are treated as they are in With.

func InitLogger

func InitLogger(c *LogConfig)

func LineAndMethodCallerEndocer

func LineAndMethodCallerEndocer(caller zapcore.EntryCaller, encoder zapcore.PrimitiveArrayEncoder)

LineAndMethodCallerEndocer serializes a caller in package/file:line package:method format.

func Panic

func Panic(args ...interface{})

Panic uses fmt.Sprint to construct and log a message, then panics.

func Panicf

func Panicf(template string, args ...interface{})

Panicf uses fmt.Sprintf to log a templated message, then panics.

func Panicw

func Panicw(msg string, keysAndValues ...interface{})

Panicw logs a message with some additional context, then panics. The variadic key-value pairs are treated as they are in With.

func Sync

func Sync() error

Sync flushes any buffered log entries.

func Warn

func Warn(args ...interface{})

Warn uses fmt.Sprint to construct and log a message.

func Warnf

func Warnf(template string, args ...interface{})

Warnf uses fmt.Sprintf to log a templated message.

func Warnw

func Warnw(msg string, keysAndValues ...interface{})

Warnw logs a message with some additional context. The variadic key-value pairs are treated as they are in With.
