Depends on: https://github.com/bear/python-twitter version 3.1 To use this script: 0. Use `pip install python-twitter` to install `python-twitter` 1. Set up Twitter authentication, as described below 2. Set up a Zulip bot user and download its `.zuliprc` config file to e.g. `~/.zuliprc` 3. Subscribe the bot to the stream that will receive Twitter updates (default stream: twitter) 4. Test the script by running it manually, like this: twitter-bot --config-file= --search="" or twitter-bot --config-file= --twitter-name="" 4. Configure a crontab entry for this script. A sample crontab entry that will process tweets every 5 minutes is: */5 * * * * /usr/local/share/zulip/integrations/twitter/twitter-bot [options] == Setting up Twitter authentications == Run this on a personal or trusted machine, because your API key is visible to local users through the command line or config file. This bot uses OAuth to authenticate with Twitter. Please create a ~/.zulip_twitterrc with the following contents: [twitter] consumer_key = consumer_secret = access_token_key = access_token_secret = In order to obtain a consumer key & secret, you must register a new application under your Twitter account: 1. Go to http://dev.twitter.com 2. Log in 3. In the menu under your username, click My Applications 4. Create a new application Make sure to go the application you created and click "create my access token" as well. Fill in the values displayed.
