Description

Uuencoding module.

Uuencoding is notoriously badly specified. This implementation is compatible with the GNU Sharutils (http://www.gnu.org/software/sharutils/).

Synopsis
encode :: [Word8] -> String
decode :: String -> Maybe [Word8]
decode' :: String -> [Maybe Word8]
chop :: Int -> String -> [String]
unchop :: [String] -> String
Documentation
encode :: [Word8] -> StringSource
Encode data.
decode :: String -> Maybe [Word8]Source
Decode data (strict).
decode' :: String -> [Maybe Word8]Source
Decode data (lazy).
chopSource
:: Intlength (1 < n <= 65, not checked)
-> String
-> [String]

Chop up a string in parts. Each string in the resulting list is prepended with the length according to the uuencode "specificiation".

Notes:

  • The length of the strings in the result will be (n -1) div 4 * 4. The -1 comes from the need to prepend the length. Keeping it to a multiple of 4 means that strings returned from encode can be chopped without requiring any changes.
  • The length of lines in GNU's sharutils is 61.
unchop :: [String] -> StringSource
Concatenate the strings into one long string. Each string is assumed to be prepended with the length according to the uuencode specification.
