|
|
|
Send Twitter tweets to a Zulip stream.
|
|
|
|
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=<path/to/.zuliprc> --search="<search-query>"
|
|
or
|
|
twitter-bot --config-file=<path/to/.zuliprc> --twitter-name="<your-twitter-handle>"
|
|
|
|
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.
