var myFlag bool flagSet := pflag.NewFlagSet("example", pflag.ExitOnError) flagSet.BoolVar(&myFlag, "myflag", false, "an example boolean flag")
var count int flagSet := pflag.NewFlagSet("example", pflag.ExitOnError) flagSet.IntVar(&count, "count", 0, "an example integer flag")
var name string flagSet := pflag.NewFlagSet("example", pflag.ExitOnError) flagSet.StringVarP(&name, "name", "n", "", "an example string flag with shorthand")This code creates a new FlagSet named "example" with an example string flag named "name". The shorthand for this flag is "n". The value of the flag is initially set to an empty string. In summary, `github.com/spf13/pflag` is a package library that provides additional features for handling command line flags and arguments in Go. It offers a FlagSet type that allows developers to create and define sets of flags for their applications, and supports a variety of data types including boolean, integer, and string flags.
