Use of flags in init() short circuits argument parsing

[sigmonsays]

calling flag.Parse() in init() breaks flags module

$ cat test/test_redis.go
package main
import (
"fmt"
"flag"
redis "Go-Redis"
)
func main() {
var configfile string
flag.StringVar(&configfile, "config", "/etc/config.ini", "configuration file")
flag.Parse()
fmt.Println("Config file", configfile)

spec := redis.DefaultSpec()
_ = spec

--- output ---

go run test/test_redis.go -config /etc/config.ini
flag provided but not defined: -config
Usage of /tmp/go-build929316002/command-line-arguments/_obj/a.out:
-redis:d=false: debug flag for go-redis
exit status 2

simple patch to move the invocation of flag.Parse() into a seperate function which must be called manually.

func init() {
runtime.GOMAXPROCS(2);
+}
+
+func ParseFlags() {
flag.Parse();
}
