huginn: A Ruby repository from Warloxx

What is Huginn?

Huginn is a system for building agents that perform automated tasks for you online. They can read the web, watch for events, and take actions on your behalf. Huginn's Agents create and consume events, propagating them along a directed graph. Think of it as a hackable Yahoo! Pipes plus IFTTT on your own server. You always know who has your data. You do.

Here are some of the things that you can do with Huginn:

Track the weather and get an email when it's going to rain (or snow) tomorrow ("Don't forget your umbrella!")
List terms that you care about and receive emails when their occurrence on Twitter changes. (For example, want to know when something interesting has happened in the world of Machine Learning? Huginn will watch the term "machine learning" on Twitter and tell you when there is a spike in discussion.)
Watch for air travel or shopping deals
Follow your project names on Twitter and get updates when people mention them
Scrape websites and receive emails when they change
Connect to Adioso, HipChat, Basecamp, Growl, FTP, IMAP, Jabber, JIRA, MQTT, nextbus, Pushbullet, Pushover, RSS, Bash, Slack, StubHub, translation APIs, Twilio, Twitter, Wunderground, and Weibo, to name a few.
Send digest emails with things that you care about at specific times during the day
Track counts of high frequency events and send an SMS within moments when they spike, such as the term "san francisco emergency"
Send and receive WebHooks
Run custom JavaScript or CoffeeScript functions
Track your location over time
Create Amazon Mechanical Turk workflows as the inputs, or outputs, of agents (the Amazon Turk Agent is called the "HumanTaskAgent"). For example: "Once a day, ask 5 people for a funny cat photo; send the results to 5 more people to be rated; send the top-rated photo to 5 people for a funny caption; send to 5 final people to rate for funniest caption; finally, post the best captioned photo on my blog."

Examples

Please checkout the Huginn Introductory Screencast!

And now, some example screenshots. Below them are instructions to get you started.

Getting Started

Docker

The quickest and easiest way to check out Huginn is to use the official Docker image. Have a look at the documentation.

Local Installation

If you just want to play around, you can simply fork this repository, then perform the following steps:

Run git remote add upstream https://github.com/cantino/huginn.git to add the main repository as a remote for your fork.
Copy .env.example to .env (cp .env.example .env) and edit .env, at least updating the APP_SECRET_TOKEN variable.
Make sure that you have MySQL or PostgreSQL installed. (On a Mac, the easiest way is with Homebrew. If you're going to use PostgreSQL, you'll need to prepend all commands below with DATABASE_ADAPTER=postgresql.)
Run bundle to install dependencies
Run bundle exec rake db:create, bundle exec rake db:migrate, and then bundle exec rake db:seed to create a development database with some example Agents.
Run bundle exec foreman start, visit http://localhost:3000/, and login with the username of admin and the password of password.
Setup some Agents!
Read the wiki for usage examples and to get started making new Agents.
Periodically run git fetch upstream and then git checkout master && git merge upstream/master to merge in the newest version of Huginn.

Note: By default, emails are intercepted in the development Rails environment, which is what you just setup. You can view them at http://localhost:3000/letter_opener. If you'd like to send real emails via SMTP when playing with Huginn locally, set SEND_EMAIL_IN_DEVELOPMENT to true in your .env file.

If you need more detailed instructions, see the Novice setup guide.

Develop

All agents have specs! And there's also acceptance tests that simulate running Huginn in a headless browser.

Install PhantomJS 2.1.1 or greater:
- Using Node Package Manager: npm install phantomjs
- Using Homebrew on OSX brew install phantomjs
Run all specs with bundle exec rspec
Run a specific spec with bundle exec rspec path/to/specific/test_spec.rb.
Read more about rspec for rails here.

Deployment

Heroku

Try Huginn on Heroku: (Takes a few minutes to setup. Read the documentation while you are waiting and be sure to click 'View it' after launch!)

Huginn works on the free version of Heroku with significant limitations. For non-experimental use, we strongly recommend Heroku's cheapest paid plan or our Docker container.

Please see the Huginn Wiki for detailed deployment strategies for different providers.

Manual installation on any server

Have a look at the installation guide.

Optional Setup

Setup for private development

See private development instructions on the wiki.

Enable the WeatherAgent

In order to use the WeatherAgent you need an API key with Wunderground. Signup for one and then change the value of api_key: your-key in your seeded WeatherAgent.

Disable SSL

We assume your deployment will run over SSL. This is a very good idea! However, if you wish to turn this off, you'll probably need to edit config/initializers/devise.rb and modify the line containing config.rememberable_options = { :secure => true }. You will also need to edit config/environments/production.rb and modify the value of config.force_ssl.
