I'm initializing a Logger variable in an init() function and then
attempting to use in the main() function. However, I'm able to Printf from
the Logger in the init() function but not inside the main() function. Any
help would be appreciated.
package main
import (
"fmt"
"log"
"io"
"os"
}
var (
logFile *os.File
logger *log.Logger
multiWriter io.Writer
)
func init() {
fmt.Println("init() function")
var logFileError error
logFile, logFileError = os.Create("gopoc.log")
if logFileError != nil {
panic(logFileError)
}
defer logFile.Close()
fmt.Println("Creating log file")
multiWriter = io.MultiWriter(logFile, os.Stdout)
logger = log.New(multiWriter, gopocLogPrefix, log.Ldate | log.Ltime |
log.Lshortfile)
logger.SetOutput(multiWriter)
fmt.Println("Created logger")
logger.Printf("Using logger") // prints to console and logFile as expected
}
func main() {
fmt.Println("main() function ") // prints to console
fmt.Println(logger) // I can see the object pointer
logger.Print("hello") // This does not print to logFile nor
os.Stdout !!!
}
