func Parse

func Parse(arg string, v interface{}) error

Parse takes a string of comma-separated k=v pairs and parses it to a struct

For example the string "name=Titanic,year=1997" could be parsed into a struct like:

type Film struct {
	Name   string `arg:"name"`
	Year   int    `arg:"year"`
	Origin string `arg:"origin,Hollywood"
}

Note that no "origin" was specified, so it will be set to the default "Hollywood". If no default value is given, the argument is required. Unused arguments are treated as errors.
