Types

type ColonSeparatedMultimapStringString

type ColonSeparatedMultimapStringString struct {
	Multimap *map[string][]string
	// contains filtered or unexported fields
}

ColonSeparatedMultimapStringString supports setting a map[string][]string from an encoding that separates keys from values with ':' and separates key-value pairs with ','. A key can be repeated multiple times, in which case the values are appended to a slice of strings associated with that key. Items in the list associated with a given key will appear in the order provided. For example: `a:hello,b:again,c:world,b:beautiful` results in `{"a": ["hello"], "b": ["again", "beautiful"], "c": ["world"]}` The first call to Set will clear the map before adding entries; subsequent calls will simply append to the map. This makes it possible to override default values with a command-line option rather than appending to defaults, while still allowing the distribution of key-value pairs across multiple flag invocations. For example: `--flag "a:hello" --flag "b:again" --flag "b:beautiful" --flag "c:world"` results in `{"a": ["hello"], "b": ["again", "beautiful"], "c": ["world"]}`
