Functions

func ApplyBinPatch

func ApplyBinPatch(src *vfs.File, dest *vfs.File, result io.Reader) error

func ApplyBinPatchStream

func ApplyBinPatchStream(src *vfs.File, dest *vfs.File, result io.Reader) error

func DmgExtractFiles

func DmgExtractFiles(r io.Reader) (args map[string][]byte, exec io.Reader, err error)

func NewDefaultTransformer

func NewDefaultTransformer(f *vfs.File) defaultTransformer

func ReadZipTar

func ReadZipTar(r io.Reader) (*zipslicer.Directory, error)

Read a tar stream produced by ZipToTar and return the zip directory. Files must be read from the zip in order or an error will be raised.

func ZipToTar

func ZipToTar(r *vfs.File, w io.Writer) error

Make a tar archive with two members: - the central directory of the zip file - the complete zip file This lets us process the zip in one pass, which normally isn't possible with the directory at the end.
