Before starting the application, you shoud set the environmental variable PKLOG. If the application is going to be run on development mode, you should set it as follows:

export PKLOG="DEVELOPMENT"

or if the application is going to be run on server, the environment variable should be set as follows:

export PKLOG="PRODUCTION"

Then you should write your code as follows:

package main

import "github.com/pezhmankasraee/go-pklog"

func main() {
	pklog.CreateLog(pklog.Error, "Hello, Error")
}

if you run the application with PKLOG="DEVELOPMENT", you will see the result on stdout, or if you run it with PKLOG="PRODUCTION" the result will be reflected on /var/log/syslog. You can see the result by:

$ cat /var/log/syslog
