        Introduction
        ============
        
        asynctelnet is an asynchronous Telnet Client and Server library for python.
        This project requires python 3.6 and later, using the anyio_ module.
        
        .. _anyio: https://anyio.readthedocs.io/
        
        asynctelnet is a heavily modified anyio-ization of the telnetlib3_ module.

        Quick Example
        -------------
        
        Authoring a Telnet Server using Streams interface that offers a basic war game:
        
        .. code-block:: python
        
            import anyio, asynctelnet
        
            async def shell(tcp):
                async with asynctelnet.TelnetServer(tcp) as stream:
                    # this will fail if no charset has been negotiated
                    await stream.send('\r\nWould you like to play a game? ')
                    inp = await reader.receive(1)
                    if inp:
                        await stream.echo(inp)
                        await stream.send('\r\nThey say the only way to win '
                                          'is to not play at all.\r\n')
        
            async def main():
                listener = await anyio.create_tcp_listener(local_port=56023)
                await listener.serve(shell)
            anyio.run(main)
        
        Authoring a Telnet Client that plays the war game with this server:
        
        .. code-block:: python
        
            import anyio, asynctelnet
        
            async def shell(tcp):
                async with asynctelnet.TelnetClient(tcp, client=True) as stream:
                    while True:
                        # read stream until '?' mark is found
                        outp = await stream.receive(1024)
                        if not outp:
                            # End of File
                            break
                        elif '?' in outp:
                            # reply all questions with 'y'.
                            await stream.send('y')
            
                        # display all server output
                        print(outp, flush=True)
             
                # EOF
                print()
            
            async def main():
                async with await connect_tcp('localhost', 56023) as client:
                    await shell(client)
            anyio.run(main)
        
        
        Command Line
        ------------
        
        Two command line scripts are distributed with this package.
        
        ``asynctelnet-client``
        
          Small terminal telnet client.  Some example destinations and options::
        
            asynctelnet-client nethack.alt.org
            asynctelnet-client --encoding=cp437 --force-binary blackflag.acid.org
            asynctelnet-client htc.zapto.org
        
        
        ``asynctelnet-server``
        
          Telnet server providing the default debugging shell.  This provides a simple
          shell server that allows introspection of the session's values, for example::
        
             tel:sh> help
             quit, writer, slc, toggle [option|all], reader, proto
        
             tel:sh> writer
             <TelnetWriter server mode:kludge +lineflow -xon_any +slc_sim server-will:BINARY,ECHO,SGA client-will:BINARY,NAWS,NEW_ENVIRON,TTYPE>
        
             tel:sh> reader
             <TelnetReaderUnicode encoding='utf8' limit=65536 buflen=0 eof=False>
        
             tel:sh> toggle all
             wont echo.
             wont suppress go-ahead.
             wont outbinary.
             dont inbinary.
             xon-any enabled.
             lineflow disabled.
        
             tel:sh> reader
             <TelnetReaderUnicode encoding='US-ASCII' limit=65536 buflen=1 eof=False>
        
             tel:sh> writer
             <TelnetWriter server mode:local -lineflow +xon_any +slc_sim client-will:NAWS,NEW_ENVIRON,TTYPE>
        
        
        Both command-line scripts accept argument ``--shell=my_module.fn_shell``
        describing a python module path to a coroutine of signature
        ``shell(reader, writer)``, just as the above examples.
