Slices and Maps

Parse list and object-like tag values

Use square brackets for slices.

roles:"['admin','editor','viewer']"

type RolesTag struct {
	Value []string `option:"value"`
}

func (t RolesTag) Tag() string {
	return "roles"
}

Use object-like syntax for maps.

settings:"{'env':'prod','tier':'backend'}"

type SettingsTag struct {
	Value map[string]string `option:"value"`
}

func (t SettingsTag) Tag() string {
	return "settings"
}

Primitive Values

Parse strings, numbers, and booleans

Nested Structs

Bind nested tag values into custom structs
