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.
.. _telnetlib3: https://telnetlib3.readthedocs.io/
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.
