Updated version of [ 558544 ] cmd.py: add instance-specific stdin/out

Browse source 
This patch adds stdin, stdout as optional arguments to the cmd.Cmd
constructor (defaulting to sys.stdin, sys.stdout), and changes the Cmd
methods throughout to use self.stdout.write() and self.stdin.foo for
output and input. This allows much greater flexibility for using cmd -
for instance, hooking it into a telnet server.

Patch for library module and for documentation.

test harnesses, administrative tools, and prototypes that will
later be wrapped in a more sophisticated interface.

A \class{Cmd} instance or subclass instance is a line-oriented
interpreter framework. There is no good reason to instantiate
\class{Cmd} itself; rather, it's useful as a superclass of an
interpreter class you define yourself in order to inherit
\class{Cmd}'s methods and encapsulate action methods.
The optional argument is the \refmodule{readline} name of a completion
key; it defaults to \kbd{Tab}. If \var{completekey} is not \code{None}
and \module{readline} is available, command completion is done
automatically.
The optional argument \var{completekey} is the \refmodule{readline} name
of a completion key; it defaults to \kbd{Tab}. If \var{completekey} is

The optional arguments \var{stdin} and \var{stdout} specify the
input and output file objects that the Cmd instance or subclass
instance will use for input and output. If not specified, they
will default to \var{sys.stdin} and \var{sys.stdout}.
