Functions

func Debug

func Debug(v ...interface{})

Debug 以Debug级别打印日志

func DefaultFormatter

func DefaultFormatter(l *logger, t time.Time, level LogLevel, v ...interface{})

DefaultFormatter 是默认的日志格式器，输出格式为

[I] [PREFIX] 2022-03-02 21:35:43 | xxxxx
[E] [PREFIX] 2022-03-02 21:35:43 | xxxxx

func Error

func Error(v ...interface{})

Error 以Error级别打印日志

func Fatal

func Fatal(v ...interface{})

Fatal 以Fatal级别打印日志

func GetCaller

func GetCaller(callLevel int, colorable bool) string

func Info

func Info(v ...interface{})

Info 以Info级别打印日志

func New

func New(out io.Writer, colorableOutput bool, prefix string, level LogLevel, formatter Formatter) *logger

New 初始化一个日志实例

func SetColorable

func SetColorable(colorable bool)

SetColorable 设置是否打印彩色日志

如果是自定义的formatter，则需要自行实现彩色输出

func SetFormatter

func SetFormatter(formatter Formatter)

SetFormatter 设置日志格式器

func SetOut

func SetOut(out io.Writer)

SetOut 设置日志输入

func SetPrefix

func SetPrefix(prefix string)

SetPrefix 设置日志前缀

func SimpleFormatter

func SimpleFormatter(l *logger, t time.Time, level LogLevel, v ...interface{})

SimpleFormatter 是简化的日志格式器，输出格式为

[I] [PREFIX] 2022-03-02 21:35:43 | xxxxx
[E] [PREFIX] 2022-03-02 21:35:43 | xxxxx

func Warn

func Warn(v ...interface{})

Warn 以Warn级别打印日志

Types

type Formatter func(l *logger, t time.Time, level LogLevel, v ...interface{})

type LogLevel

type LogLevel int

const (
	LevelDebug LogLevel = iota
	LevelInfo
	LevelWarn
	LevelError
	LevelFatal
)
