EasyLog

A Simple & Easy Logging package for Go(golang). EasyLog is highly stable and thread-safe because it uses the standard log package.

Installation

$ go get github.com/Astera-org/easylog

Usage

If you initialize easylog in func main(), it allows you to write log with same logger from any file in your project that is importing easylog package.

import "github.com/Astera-org/easylog"

func main() {
    if err := easylog.Init("mydir/mylog.txt"); err != nil {
        panic(err)
    }
    // easylog.Debug calls will be ignored, since DEBUG < INFO
    easylog.SetLevel(easylog.INFO)
    // You can log strings as you would to fmt.Println
    easylog.Info("Hey", "dude")
    // You can log format strings as you would to fmt.Printf
    easylog.Errorf("I have %d computers", 12)
}

See easylog_test.go for more examples.

Level (default: DEBUG)

Five levels defined below.

• DEBUG
• INFO
• WARN
• ERROR
• FATAL

You can set one of them for output level. Each function for levels allows you to output messages to level you want: log.Debug() log.Info() log.Warn() log.Error() log.Fatal(). The log.Fatal(), like built-in log package, outputs a message and then terminates the program.

MaxSize (default: 1 MB)

You can set max size of log files in megabytes with log.SetMaxSize(). If log file exceed max size, the file will be changed to backup (eg. sample.log.bak.20060102150405) and create new one automatically.
