Use flag var

[tcnksm]

Use flag.Var (This is just my preference),

$ make build && ./bin/gcli new -F flag -f file:string -f worker:int -f debug:bool test

This will generate,

var (
         file   string
         worker int
         debug  bool
)

flags.StringVar(&file, "file", "", "")
flags.IntVar(&worker, "worker", 0, "")
flags.BoolVar(&debug, "debug", false, "")
