Does anyone know how to set/modify the log dir in the golang source code?
I want to set the log dir in the soure code, instead of -log_dir=
in the cmdline
This is a hack I have seen lying around: set the flags in code. Also very good for setting log levels from code.
package main
import (
"flag"
"github.com/golang/glog"
)
func main() {
flag.Parse()
glog.Info("hi_a")
flag.Lookup("logtostderr").Value.Set("true")
glog.Info("hi_b")
flag.Lookup("log_dir").Value.Set("/path/to/log/dir")
glog.V(4).Info("v4a")
flag.Lookup("v").Value.Set("10")
glog.V(4).Info("v4b")
//etc.
}
>>> hi_b
>>> v4b
