|
|
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 \code{'-'} 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 \code{'rb'} or \code{'wb'} on Windows.
|
|
|
|
This code was contributed by Lance Ellinghouse, and modified by Jack
|
|
Jansen.

The \module{uu} module defines the following functions:
|
|
|
|
\begin{funcdesc}{encode}{in_file, out_file\optional{, name\optional{, mode}}}
|
|
Uuencode file \var{in_file} into file \var{out_file}. The uuencoded
|
|
file will have the header specifying \var{name} and \var{mode} as
|
|
the defaults for the results of decoding the file. The default
|
|
defaults are taken from \var{in_file}, or \code{'-'} and \code{0666}
|
|
respectively.
|
|
\end{funcdesc}
|
|
|
|
\begin{funcdesc}{decode}{in_file\optional{, out_file\optional{, mode}}}
|
|
This call decodes uuencoded file \var{in_file} placing the result on
|
|
file \var{out_file}. If \var{out_file} is a pathname, \var{mode} is
|
|
used to set the permission bits if the file must be
|
|
created. Defaults for \var{out_file} and \var{mode} are taken from
|
|
the uuencode header. However, if the file specified in the header
|
|
already exists, a \exception{uu.Error} is raised.
|
|
\end{funcdesc}
|
|
|
|
\begin{excclassdesc}{Error}{}
|
|
Subclass of \exception{Exception}, this can be raised by
|
|
\function{uu.decode()} under various situations, such as described
|
|
above, but also including a badly formated header, or truncated
|
|
input file.
|
|
\end{excclassdesc}
