check CONTRIBUTING.md.

Example

package main

import (
	"fmt"
	"os"

	"github.com/mediaFORGE/gol"
	"github.com/mediaFORGE/gol/formatters"

	field_severity "github.com/mediaFORGE/gol/fields/severity"
	filter_severity "github.com/mediaFORGE/gol/filters/severity"
	logger_simple "github.com/mediaFORGE/gol/loggers/simple"
	manager_simple "github.com/mediaFORGE/gol/managers/simple"
)

// Log holds the application LogManager instance.
var Log gol.LoggerManager

func init() {
	fmt.Println("init():start")
	Log = manager_simple.New()

	f := filter_severity.New(field_severity.Info)
	formatter := formatters.Text{}
	logger := logger_simple.New(f, formatter, os.Stdout)
	Log.Register("main", logger)

	channel := make(chan *gol.LogMessage, 10)
	Log.Run(channel)
	Log.Send(gol.NewInfo("message", "main.Log has been configured"))
	channel <- gol.NewInfo("message", "this message was sent directly to the log manager channel")

	fmt.Println("init():end")
}

func main() {
	fmt.Println("Started application.")
	defer func() {
		Log.Close()
		fmt.Println("Ended application.")
	}()

	// send 10,000 messages
	for i := 0; i < 10000; i++ {
		Log.Send(gol.NewInfo("i", fmt.Sprintf("%d", i)))
	}
	fmt.Println("Ending application...")
}
