12.16 uu -- Encode and decode uuencode files
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.
This code was contributed by Lance Ellinghouse, and modified by Jack Jansen.
The uu module defines the following functions:
-
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
'-'
and0666
respectively.
- 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 uu.Error is raised.
- Subclass of Exception, this can be raised by uu.decode() under various situations, such as described above, but also including a badly formated header, or truncated input file.
