Functions

func Dump

func Dump(r io.Reader) (string, error)

func MacTime

func MacTime(t uint32) time.Time

func MakePrefix

func MakePrefix(records map[int][]byte, rforkSize, rForkMinOffset int64) (buf []byte, rForkOffset int64)

Slightly peculiar

func Sidecar

func Sidecar(name string) string

Types

type AppleDouble

type AppleDouble struct {
	// Basic filesystem metadata
	CreateTime, ModTime, BkTime, AccTime time.Time
	Locked                               bool

	// Stored in various ways across software versions, nonetheless important
	Comment string

	// File-and-directory FinderInfo
	Flags    uint16
	Location struct{ Y, X int16 }
	XFlags   uint16 // ignore the rarely used "filename display script" function

	// File-only FinderInfo
	Type    [4]byte
	Creator [4]byte

	// Directory-only FinderInfo
	Rect   struct{ T, L, B, R int16 }
	View   int16 // 0 is not a valid value, use 256 (icon view)
	Scroll struct{ Y, X int16 }
}

Everything that we would want to put in an AppleDouble file, except for a resource fork, because that's big. Excludes some of the Finder info fields that become meaningless when moving to a different disk
