  --session SESSION     __Secure-1PSID cookie
  --session_ts SESSION_TS
                        __secure_1psidts cookie.

Quick mode

$ export BARD_QUICK="true"
$ export BARD__Secure_1PSID="<__Secure-1PSID>"
$ export BARD__Secure_1PSIDTS="<__Secure-1PSIDTS>"
$ python3 -m Bard

Environment variables can be placed in .zshrc.

Example bash shortcut:

# USAGE1: bard QUESTION
# USAGE2: echo "QUESTION" | bard
bard () {
	export BARD_QUICK=true
	export BARD__Secure_1PSID=<__Secure-1PSID>
	export BARD__Secure_1PSIDTS=<__Secure-1PSIDTS>
	python3 -m Bard "${@:-$(</dev/stdin)}" | tail -n+7
}

Implementation:

from os import environ
from Bard import Chatbot

Secure_1PSID = environ.get("BARD__Secure_1PSID")
Secure_1PSIDTS = environ.get("BARD__Secure_1PSIDTS")
chatbot = Chatbot(Secure_1PSID, Secure_1PSIDTS)

answer = chatbot.ask("Hello, how are you?")

print(answer['content']

Async Implementation:

import asyncio
from os import environ
from Bard import AsyncChatbot

Secure_1PSID = environ.get("BARD__Secure_1PSID")
Secure_1PSIDTS = environ.get("BARD__Secure_1PSIDTS")

async def main():
    chatbot = await AsyncChatbot.create(Secure_1PSID, Secure_1PSIDTS)
    response = await chatbot.ask("Hello, how are you?")
    print(response['content'])

asyncio.run(main())

[!IMPORTANT] The cookies expire after a short period; ensure you update them as frequent as possible.
