# gologrotate
logrotate for golang
# Example
## Code
```
package main
import (
"bufio"
"fmt"
"log"
"os"
"os/signal"
"syscall"
"time"
"github.com/tkuchiki/gologrotate"
)
func main() {
var writer *bufio.Writer
var err error
var f *os.File
logpath := "/tmp/log"
f, err = os.OpenFile(logpath, os.O_WRONLY|os.O_CREATE, 0644)
writer = bufio.NewWriter(f)
sigChan := make(chan os.Signal, 1)
signal.Notify(sigChan,
syscall.SIGUSR1)
go func() {
for {
s := <-sigChan
switch s {
case syscall.SIGUSR1:
log.Println("Received SIGUSR1")
writer, err = gologrotate.Rotate(writer, f, logpath, "", os.O_WRONLY|os.O_CREATE, 0644)
}
}
}()
i := 0
for {
_, _ = writer.Write([]byte(fmt.Sprintf("%d\n", i)))
writer.Flush()
i++
time.Sleep(10 * time.Millisecond)
}
}
```
