list := Flag{}

fs := flag.NewFlagSet("test", flag.ContinueOnError)
fs.Var(&list, "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", list)

Types ¶

type Flag ¶

type Flag []string

Flag is a flag.Value implementation which represents an ordered set of strings.

For example, this allows you to construct a flag that would behave like:

-myflag Foo
-myflag Bar
-myflag Bar

And then myflag would be []string{"Foo", "Bar", "Bar"}

func (*Flag) Set ¶

func (f *Flag) Set(val string) error

Set implements flag.Value's Set function.

func (Flag) String ¶

func (f Flag) String() string
