The default action of UserWatcher is to print the tweets, but you can ask any other action instead. For instance, here is how to only print the tweets that are actually written by John D. Cook (not the ones he retweets):

from twittcher import UserWatcher

def my_action(tweet):
    if tweet.username == "JohnDCook":
        print(tweet)

UserWatcher("JohnDCook", action=my_action).watch_every(120)

2. Control a distant machine through Twitter !

Every 60 seconds, for any of my new tweets of the form cmd: my_command, run my_command in a terminal. Using simple tweets I can control any distant computer running this script.

import subprocess
from twittcher import UserWatcher

def my_action(tweet):
    """ Execute the tweet's command, if any. """
    if tweet.text.startswith("cmd: "):
        subprocess.Popen( tweet.text[5:], shell=True )

# Watch my account and react to my tweets
bot = UserWatcher("Zulko___", action=my_action)
bot.watch_every(60)

For instance, the tweet cmd: firefox will open Firefox on the computer, and the tweet cmd: echo "Hello" will have the computer print Hello in a terminal.

3. Watch search results and send alert mails

Every 20 seconds, send me all the new tweets in the Twitter search results for chocolate milk.

from twittcher import TweetSender, SearchWatcher
sender = TweetSender(smtp="smtp.gmail.com", port=587,
                     login="tintin.zulko@gmail.com",
                     password="fibo112358", # be nice, don't try.
                     to_addrs="tintin.zulko@gmail.com", # where to send
                     sender_id = "chocolate milk")
bot = SearchWatcher("chocolate milk", action=sender.send)
bot.watch_every(20)

4. Multibot watching

If you want to run several bots at once, make sure that you leave a few seconds between the requests of the different bots. Here is how you print the new tweets of John D. Cook, Mathbabe, and Eolas. Each of them is watched every minute, with 20 seconds between the requests of two bots:

import time
import itertools
from twittcher import UserWatcher

bots = [ UserWatcher(user) for user in
         ["JohnDCook", "mathbabedotorg",  "Maitre_Eolas"]]

for bot in itertools.cycle(bots):
    bot.watch()
    time.sleep(20)

5. Saving the tweets

A bot can save to a file the tweets that it has already seen, so that in future sessions it will remember not to process these tweets again, in case they still appear on the watched page.

from twittcher import SearchWatcher
bot = SearchWatcher("chocolate milk", database="choco.db")
bot.watch_every(20)
