UnpackIt

This Go library allows you to easily unpack the following files using magic numbers:

• tar.gz
• tar.bzip2
• tar.xz
• zip
• tar

Usage

Unpack a file:

    file, _ := os.Open(test.filepath)
    destPath, err := gcompress.Unpack(file, tempDir)

Unpack a stream (such as a http.Response):

    res, err := http.Get(url)
    destPath, err := gcompress.Unpack(res.Body, tempDir)

Functions

func Unpack

func Unpack(reader io.Reader, destPath string) (string, error)

Unpack unpacks a compressed stream. Magic numbers are used to determine what decompressor and/or unarchiver to use.

func Untar

func Untar(data io.Reader, destPath string) (string, error)

Untar unarchives a TAR archive and returns the final destination path or an error

func Unzip

func Unzip(r io.Reader, destPath string) (string, error)

Unzip unpacks a ZIP stream. When given a os.File reader it will get its size without reading the entire zip file in memory.
