      1 :mod:`uu` --- Encode and decode uuencode files

     10 --------------
     11 
     12 This module encodes and decodes files in uuencode format, allowing arbitrary
     13 binary data to be transferred over ASCII-only connections. Wherever a file
     14 argument is expected, the methods accept a file-like object.  For backwards
     15 compatibility, a string containing a pathname is also accepted, and the
     16 corresponding file will be opened for reading and writing; the pathname ``'-'``
     17 is understood to mean the standard input or output.  However, this interface is
     18 deprecated; it's better for the caller to open the file itself, and be sure
     19 that, when required, the mode is ``'rb'`` or ``'wb'`` on Windows.

     27 The :mod:`uu` module defines the following functions:
     28 
     29 
     30 .. function:: encode(in_file, out_file[, name[, mode]])
     31 
     32    Uuencode file *in_file* into file *out_file*.  The uuencoded file will have the
     33    header specifying *name* and *mode* as the defaults for the results of decoding
     34    the file. The default defaults are taken from *in_file*, or ``'-'`` and ``0666``
     35    respectively.
     36 
     37 
     38 .. function:: decode(in_file[, out_file[, mode[, quiet]]])
     39 
     40    This call decodes uuencoded file *in_file* placing the result on file
     41    *out_file*. If *out_file* is a pathname, *mode* is used to set the permission
     42    bits if the file must be created. Defaults for *out_file* and *mode* are taken
     43    from the uuencode header.  However, if the file specified in the header already
     44    exists, a :exc:`uu.Error` is raised.
     45 
     46    :func:`decode` may print a warning to standard error if the input was produced
     47    by an incorrect uuencoder and Python could recover from that error.  Setting
     48    *quiet* to a true value silences this warning.
     49 
     50 
     51 .. exception:: Error()
     52 
     53    Subclass of :exc:`Exception`, this can be raised by :func:`uu.decode` under
     54    various situations, such as described above, but also including a badly
     55    formatted header, or truncated input file.
