# Writer Hooks for Logrus
Send logs of given levels to any object with `io.Writer` interface.
## Usage
If you want for example send high level logs to `Stderr` and
logs of normal execution to `Stdout`, you could do it like this:
```go
package main
import (
"io/ioutil"
"os"
log "github.com/sirupsen/logrus"
"github.com/sirupsen/logrus/hooks/writer"
)
func main() {
log.SetOutput(ioutil.Discard) // Send all logs to nowhere by default
log.AddHook(&writer.Hook{ // Send logs with level higher than warning to stderr
Writer: os.Stderr,
LogLevels: []log.Level{
log.PanicLevel,
log.FatalLevel,
log.ErrorLevel,
log.WarnLevel,
},
})
log.AddHook(&writer.Hook{ // Send info and debug logs to stdout
Writer: os.Stdout,
LogLevels: []log.Level{
log.InfoLevel,
log.DebugLevel,
},
})
log.Info("This will go to stdout")
log.Warn("This will go to stderr")
}
```
