'''
Example of using Skink to build a (very) minimalist web messaging app.
'''

# First, we start the Tornado server:

import logging
logging.basicConfig(level=logging.DEBUG)

import skink.server as server
import skink.remote as remote

import threading
threading.Thread(target=server.start, args=()).start()

# Second, we wait for Alice and Bob to connect on the page:

print("Open your browser on pages http://localhost:9000/alice "
      "and http://localhost:9000/bob")

print('Waiting for clients on pages /alice and /bob ...')
import time
while len(server.LISTENERS.get('/alice', [])) < 1 \
   or len(server.LISTENERS.get('/bob', [])) < 1:
    time.sleep(0.1)
    print('LISTENERS', server.LISTENERS)
print('Got a client')

# Finally, we register the input fields of Alice and Bob to send messages
# to each other by replacing the content of a div.

alice = remote.RemotePage('/alice')
bob = remote.RemotePage('/bob')

alice.document.getElementById('hello').innerHTML = "Hello Alice"
bob.document.getElementById('hello').innerHTML = "Hello Bob"


def alice_keypress():
    z = alice.document.getElementById('message').value._eval()
    bob.document.getElementById('hello2').innerHTML = z


def bob_keypress():
    z = bob.document.getElementById('message').value._eval()
    alice.document.getElementById('hello2').innerHTML = z


@alice.on_open
def setup_alice():
    alice.document.getElementById('message').onkeypress = alice_keypress


@bob.on_open
def setup_bob():
    bob.document.getElementById('message').onkeypress = bob_keypress
