Variables

var (
	// ErrWrongSize is returned if given slice have the wrong size
	ErrWrongSize = errors.New("Given slice must have same size as os.Arg")

	// ErrWrongArguments is returned if one of given arguments is empty
	ErrWrongArguments = errors.New("Arguments can't be empty")
)

Functions

func Replace

func Replace(from, to string) error

Replace replaces one argument in process command

WARNING: Be careful with using os.Args or options.Parse result as 'from' argument. After using this method given variable content will be replaced. Use strutil.Copy method in this case.

Example

password := "mySuppaPass"

// Replacing known password to asterisks
err := Replace(password, "*****************")

if err != nil {
	fmt.Printf("Error: %v\n", err)
}

func Set

func Set(args []string) error

Set changes current process command in process tree

Example

args := os.Args

// Mask first argument
args[1] = strings.Repeat("*", len(args[1]))

err := Set(args)

if err != nil {
	fmt.Printf("Error: %v\n", err)
}
