Functions

func NormalizeFilesystemPath

func NormalizeFilesystemPath(abs bool, appName string) func(*Opt) error

NormalizeFilesystemPath cleans a directory specification, expands the ~ home folder shortcut, and if abs is set to true, returns the absolute path from filesystem root.

func NormalizeNetworkAddress

func NormalizeNetworkAddress(defaultPort string,
	userOnly bool) func(*Opt) error

NormalizeNetworkAddress checks correctness of a network address specification, and adds a default path if needed, and enforces whether the port requires root permission and clamps it if not.
