:mod:`uu` --- Encode and decode uuencode files
|
|
==============================================
|
|
|
|
.. module:: uu
|
|
:synopsis: Encode and decode files in uuencode format.
|
|
.. moduleauthor:: Lance Ellinghouse
|
|
|
|
|
|
This module encodes and decodes files in uuencode format, allowing arbitrary
|
|
binary data to be transferred over ASCII-only connections. Wherever a file
|
|
argument is expected, the methods accept a file-like object. For backwards
|
|
compatibility, a string containing a pathname is also accepted, and the
|
|
corresponding file will be opened for reading and writing; the pathname ``'-'``
|
|
is understood to mean the standard input or output. However, this interface is
|
|
deprecated; it's better for the caller to open the file itself, and be sure
|
|
that, when required, the mode is ``'rb'`` or ``'wb'`` on Windows.

The :mod:`uu` module defines the following functions:
|
|
|
|
|
|
.. function:: encode(in_file, out_file, name=None, mode=None)
|
|
|
|
Uuencode file *in_file* into file *out_file*. The uuencoded file will have
|
|
the header specifying *name* and *mode* as the defaults for the results of
|
|
decoding the file. The default defaults are taken from *in_file*, or ``'-'``
|
|
and ``0o666`` respectively.
|
|
|
|
|
|
.. function:: decode(in_file, out_file=None, mode=None, quiet=False)
|
|
|
|
This call decodes uuencoded file *in_file* placing the result on file
|
|
*out_file*. If *out_file* is a pathname, *mode* is used to set the permission
|
|
bits if the file must be created. Defaults for *out_file* and *mode* are taken
|
|
from the uuencode header. However, if the file specified in the header already
|
|
exists, a :exc:`uu.Error` is raised.
|
|
|
|
:func:`decode` may print a warning to standard error if the input was produced
|
|
by an incorrect uuencoder and Python could recover from that error. Setting
|
|
*quiet* to a true value silences this warning.
|
|
|
|
|
|
.. exception:: Error()
|
|
|
|
Subclass of :exc:`Exception`, this can be raised by :func:`uu.decode` under
|
|
various situations, such as described above, but also including a badly
|
|
formatted header, or truncated input file.
