Package log implements leveled logging.

https://pkg.go.dev/github.com/hit9/log

Example

package main

import (
	"github.com/hit9/log"
)

var logger = log.Get("Name")

func main() {
	logger.SetLevel(log.INFO)
	logger.Debug("This is a debug message")
	logger.Info("This is a info message")
	logger.Warn("This is a warning message")
	logger.Error("This is an error message")
	logger.Warn("This is a number %v", 1)
}

Overview

Package log implements a minimal leveled logging library.

Example

var logger = log.Get("ExampleName")

func main() {
	logger.SetLevel(log.INFO)
	logger.Debug("This is a debug message")
	logger.Info("This is a info message")
	logger.Warn("This is a warning message")
	logger.Error("This is an error message")
	logger.Warnf("This is a number %v", 1)
}

Types

type Logger

type Logger struct {
	// contains filtered or unexported fields
}

Logger abstraction.

func Get

func Get(name string) *Logger

New creates a new Logger.

func (*Logger) Debug

func (l *Logger) Debug(format string, a ...interface{}) error

Debug formats and logs message with level DEBUG.

func (*Logger) DisableCallerSourceLogging

DisableCallerSourceLogging disables the logging for caller source. This sets to true by default.

func (*Logger) Error

func (l *Logger) Error(format string, a ...interface{}) error

Error formats and logs message with level ERROR.

func (*Logger) Fatal

func (l *Logger) Fatal(format string, a ...interface{})

Fatal formats and logs message with level FATAL.

func (*Logger) GetLevel

func (l *Logger) GetLevel() int

GetLevel gets the logging level.

func (*Logger) Info

func (l *Logger) Info(format string, a ...interface{}) error

Info formats and logs message with level INFO.

func (*Logger) Log

func (l *Logger) Log(level int, format string, a ...interface{}) error

func (*Logger) SetCallerDepth

func (l *Logger) SetCallerDepth(callerDepth int)

SetCallerDepth sets the caller depth for this logger.

func (*Logger) SetColored

func (l *Logger) SetColored(b bool)

SetColored sets the color enability.

func (*Logger) SetLevel

func (l *Logger) SetLevel(level int)

SetLevel sets the logging level.

func (*Logger) SetNameLength

func (l *Logger) SetNameLength(n int)

SetNameLength sets the name length.

func (*Logger) SetWriter

func (l *Logger) SetWriter(w io.Writer)

SetWriter sets the writer.

func (*Logger) Smart

func (l *Logger) Smart(e error, format string, a ...interface{})

Smart formats and logs message in different levels according to given error.
