Functions

func Extract

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

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

func IsGzipped(o *Opts)

func Subdir

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

Subdir reads the tarball from r and 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.
