How to install

python -m pip install --upgrade micropython_eliza

How to run

Start chat in the console:

python -m micropython_eliza.chat

See an example conversation:

python -m micropython_eliza.demo

How to use

import sys
from micropython_eliza import eliza

USERNAME_IN_CHAT = "YOU"

agent = eliza.create()
print("\n<press enter with no message to exit>")
print(f"{agent.name()}: {agent('')}")
print(f"{USERNAME_IN_CHAT}: ")
msg = sys.stdin.readline().strip()
while msg:
    print(f"{agent.name()}: {agent(msg)}")
    print(f"{USERNAME_IN_CHAT}: ")
    msg = sys.stdin.readline().strip()

To enable printing info and debug messages, provide log handlers, e.g.:

agent = eliza.create(log_info=print, log_debug=print)
