func Archive ¶

func Archive(inFilePath string, writer io.Writer, progress ProgressFunc) error

Archive compresses a file/directory to a writer

If the path ends with a separator, then the contents of the folder at that path are at the root level of the archive, otherwise, the root of the archive contains the folder as its only item (with contents inside).

If progress is not nil, it is called for each file added to the archive.

func ArchiveFile ¶

func ArchiveFile(inFilePath string, outFilePath string, progress ProgressFunc) error

ArchiveFile compresses a file/directory to a file

See Archive() doc

tmpDir, err := ioutil.TempDir("", "test_zip")
if err != nil {
	panic(err)
}
defer func() {
	_ = os.RemoveAll(tmpDir)
}()

outFilePath := filepath.Join(tmpDir, "foo.zip")

progress := func(archivePath string) {
	fmt.Println(archivePath)
}

err = ArchiveFile("testdata/foo", outFilePath, progress)
if err != nil {
	panic(err)
}

Output:

foo/bar
foo/baz/aaa

func Unarchive ¶

func Unarchive(reader io.ReaderAt, readerSize int64, outFilePath string, progress ProgressFunc) error

Unarchive decompresses a reader to a directory

The data's size is required because the zip reader needs it.

The archive's content will be extracted directly to outFilePath.

If progress is not nil, it is called for each file extracted from the archive.

func UnarchiveFile ¶

func UnarchiveFile(inFilePath string, outFilePath string, progress ProgressFunc) error

UnarchiveFile decompresses a file to a directory

See Unarchive() doc

tmpDir, err := ioutil.TempDir("", "test_zip")
if err != nil {
	panic(err)
}
defer func() {
	_ = os.RemoveAll(tmpDir)
}()

progress := func(archivePath string) {
	fmt.Println(archivePath)
}

err = UnarchiveFile("testdata/foo.zip", tmpDir, progress)
if err != nil {
	panic(err)
}

Output:

foo/bar
foo/baz/aaa
