Class Method Details

.convert(file, current_format, destination_format, sanitize = false) ⇒ StringIO

Convert an archived application, the file, from the current_format to the destination_format.

Parameters:

  • file (IO) —

    archive file that shall be converted

  • current_format (String) —

    represented by well-known file extensions, e.g. zip or tar.gz

  • destination_format (String) —

    represented by well-known file extensions, e.g. zip or tar.gz

  • sanitize (Boolean) (defaults to: false) —

    if true, the application will be sanitized, meaning if all data is in one folder it will be moved one level up so that the application data is not nested in another directory
