Description
Server/client communication via TCP sockets.
The module implements TCP communication between
a daemon-like Server
and a simple
Client
.
The Server
class is meant to be
run as a daemon-like app. The user should
override the create_parser()
method to define the daemon behaviour upon
reception of a message from a Client
.
The base class provides support for the
message ‘quit’, which will terminate the
daemon. Any other message will be met with
a help-like reply.
The Client
class communicates with
the Server
sending a text string.
The ArgumentParser
class and
MessageError
exception are
necessary to override some unwanted
default behaviour of the
argparse
library.
The module is based upon this tutorial.
