var DefaultExclusionPattern = regexp.MustCompile("((^\\.git\\/)|(\\/.git\\/)|(\\/.git$))")

Types

type Tar

type Tar interface {
	// SetExclusionPattern sets the exclusion pattern for tar
	// creation
	SetExclusionPattern(*regexp.Regexp)

	// CreateTarFile creates a tar file in the base directory
	// using the contents of dir directory
	// The name of the new tar file is returned if successful
	CreateTarFile(base, dir string) (string, error)

	// CreateTarStreamWithLogging creates a tar from the given directory
	// and streams it to the given writer.
	// An error is returned if an error occurs during streaming.
	// Archived file names are written to the logger if provided
	CreateTarStreamWithLogging(dir string, includeDirInPath bool, writer io.Writer, logger io.Writer) error
