stringsetflag

Example demonstrates how to use stringlistflag.

sset := Flag{}

fs := flag.NewFlagSet("test", flag.ContinueOnError)
fs.Var(&sset, "color", "favorite color, may be repeated.")
fs.SetOutput(os.Stdout)

fs.PrintDefaults()

// Flag parsing.
fs.Parse([]string{"-color", "Violet", "-color", "Red", "-color", "Violet"})
fmt.Printf("Value is: %s\n", sset)

fmt.Println("Likes Blue:", sset.Data.Has("Blue"))
fmt.Println("Likes Red:", sset.Data.Has("Red"))

Output:
