golog

本日志库初期为本人的golang提供日志支持

基础代码基于golang的官方日志库修改

主要功能

• 增加了log级别设置

• 去掉默认全局日志接口，使用日志需要实例化给出模块名方便跟踪

• 可根据模块名设定所有模块日志的层级方便切换想看到的日志

• 根据内容标记日志颜色

安装方法

go get github.com/davyxu/golog

使用方法

• 基本使用

  var log *golog.Logger = golog.New("test")

  log.Debugln("hello world")

• 层级设置

  golog.SetLevelByString( "test", "info")

备注

感觉不错请star, 谢谢!

Overview

Package log implements a simple logging package. It defines a type, Logger, with methods for formatting output. It also has a predefined 'standard' Logger accessible through helper functions Print[f|ln], Fatal[f|ln], and Panic[f|ln], which are easier to use than creating a Logger manually. That logger writes to standard error and prints the date and time of each logged message. The Fatal functions call os.Exit(1) after writing the log message. The Panic functions call panic after writing the log message.

Constants

const (
	// Bits or'ed together to control what's printed. There is no control over the
	// order they appear (the order listed here) or the format they present (as
	// described in the comments).  A colon appears after these items:
	//	2009/01/23 01:23:23.123123 /a/b/c/d.go:23: message
	Ldate         = 1 << iota     // the date: 2009/01/23
	Ltime                         // the time: 01:23:23
	Lmicroseconds                 // microsecond resolution: 01:23:23.123123.  assumes Ltime.
	Llongfile                     // full file name and line number: /a/b/c/d.go:23
	Lshortfile                    // final file name element and line number: d.go:23. overrides Llongfile
	LstdFlags     = Ldate | Ltime // initial values for the standard logger

)

These flags define which text to prefix to each log entry generated by the Logger.

	Blue
	Purple
	DarkGreen
	White
)

func ColorFromLevel

func ColorFromLevel(l Level) Color

type ColorFile

type Logger

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

A Logger represents an active logging object that generates lines of output to an io.Writer. Each logging operation makes a single call to the Writer's Write method. A Logger can be used simultaneously from multiple goroutines; it guarantees to serialize access to the Writer.

func (*Logger) Output

func (self *Logger) Output(calldepth int, prefix string, text string, c Color, out io.Writer) error

Output writes the output for a logging event. The string s contains the text to print after the prefix specified by the flags of the Logger. A newline is appended if the last character of s is not already a newline. Calldepth is used to recover the PC and is provided for generality, although at the moment on all pre-defined paths it will be 2.
