GetInt64 returns flag value as int64 or defaultValue when not set/invalid.

func GetInt64Pflag

func GetInt64Pflag(fs *pflag.FlagSet, name string, defaultValue int64) int64

GetInt64Pflag returns flag value as int64 or defaultValue when not set/invalid.

func GetIntPflag

func GetIntPflag(fs *pflag.FlagSet, name string, defaultValue int) int

GetIntPflag returns flag value as int or defaultValue when not set/invalid.

func GetString

func GetString(fs *flag.FlagSet, name, defaultValue string) string

GetString returns flag value or defaultValue when not set.

func GetStringPflag

func GetStringPflag(fs *pflag.FlagSet, name, defaultValue string) string

GetUint64 returns flag value as uint64 or defaultValue when not set/invalid.

func HasFlag

func HasFlag(fs *flag.FlagSet, name string) bool

HasFlag checks if a command-line flag is set in the given FlagSet

func HasFlagInArgs

func HasFlagInArgs(args []string, name string) bool

HasFlagInArgs checks if a flag is present in args (supports -name, --name, -name=value, --name=value)

func HasFlagInOSArgs

func HasFlagInOSArgs(name string) bool

HasFlagInOSArgs checks if a flag is present in os.Args

func HasFlagPflag

func HasFlagPflag(fs *pflag.FlagSet, name string) bool

HasFlagPflag checks if a command-line flag is set in the given pflag.FlagSet. It returns true if the flag was explicitly set (e.g. --port 8080 or -p 8080).

func ReadPasswordFromFile

func ReadPasswordFromFile(filePath string) (string, error)

ReadPasswordFromFile reads password from file (security improvement). Path is validated with path traversal check; relative paths are resolved to absolute. File content is trimmed of leading and trailing whitespace.
