Log package with levels and color for Go

Example

package main
  
import (
        "flag"

        "github.com/mickep76/log"
)

func main() {
        lvlArg := flag.String("lvl", "debug", "Log level [debug|info|warn|err|crit].")
        flag.Parse()

        lvl, err := log.ToLevel(*lvlArg)
        if err != nil {
                log.Fatal(err)
        }
        log.SetLevel(lvl)

        log.Debug("debug level")
        log.Info("info level")
        log.Warn("warn level")
        log.Error("error level")
        log.Fatal("critical level")
}
