func (f *FlagSet) StringVarP(p *string, name string, shorthand string, value string, usage string)
import "github.com/spf13/pflag" // Define flags with StringVarP var input string flagSet := pflag.NewFlagSet("my_program", pflag.ExitOnError) flagSet.StringVarP(&input, "input", "i", "", "input file") // Parse command-line arguments flagSet.Parse(os.Args[1:]) // Use the parsed flags fmt.Printf("input file: %s\n", input)In the code above, a new FlagSet is created, and the `StringVarP` function is used to create a new flag named "input" with the shorthand "i". The `input` variable is passed as a pointer to `&input`, which will store the parsed argument. After parsing the command-line arguments using `Parse`, the value of `input` can be used in the program. Overall, the `github.com/spf13/pflag` package library provides a set of flexible and easy-to-use APIs for handling command-line flags in Go.
