Functions

func Extract

func Extract(r io.Reader, dir string) error

Extract reads the tarball from r and writes it into dir. Copied and modified from golang.org/x/build/internal/untar.

func Subdir

func Subdir(r io.Reader, subdir string) io.ReadCloser

Subdir reads the tarball from r and streams the files in the given subdirectory to the returned io.ReadCloser as a tarball with the subdirectory's path trimmed from each file's name.

If the subdirectory is empty or non-existent, the returned io.ReadCloser is closed with ErrEmptySubdir.
