Do you speak Python?

PythonSpeak is XMPP-room-based chat client with a twist -- you must speak in Python! It works like Python's interactive shell, but everything you type is sent to your chat room and added to the Python shell of everybody in the room. You can write whole classes together, one line at the time. In result, you have a pseudo-shared state of your script. It might be best described as shared Python shell.

PythonSpeak is just an experiment at the moment. It does work (for me at least), but the code isn't pretty.

NOTE: These modules have been blacklisted:

• os
• subprocess

That means nobody in the chat room can use them. It does not matter if the sender is using PythonSpeak or not, because the code is checked on receive. BlacklistedError is raised when someone tries to use any of the blacklisted modules.

Try it

Clone the repo, then:

$ python pythonspeak.py

You can still test the project if you have only one XMPP account to play with. Every piece of code is executed on receive. This is intended -- you get a feeling when others received the message. So just type anything into the shell. If PythonSpeak works, it will be sent to the chat room and executed when you get the code back from the chat room.

The shell interface is currently coded with the help of backspace characters. This is to provide dynamic prompt (which changes based on input state) and to prevent cursor misplacement when you receive a message from another user.

Chat session example

This is me having two terminals opened, where I connected to the same room with two different XMPP accounts. The shell "conversation" looks the same on both sides.
