Instance Method Details

#fingerprint(fingerprints, opts = {}) {|Mixed, String, String| ... } ⇒ Object

Format should be the following: {

file_path_1: {
  md5_hash_1: version_1,
  md5_hash_2: [version_2]
},
file_path_2: {
  md5_hash_3: [version_1, version_2],
  md5_hash_4: version_3
}

} Note that the version can either be an array or a string

Options Hash (opts):

  • :show_progression (Boolean) —

    Wether or not to display the progress bar

Yields:

  • (Mixed, String, String) —

    version/s, url, hash The version associated to the fingerprint of the url
