# Huginn.  Your agents are standing by.

## 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 event flow graph.  Think of it as Yahoo! Pipes plus IFTTT on your own server.  You always know who has your data.  You do.

#### We're just getting started, but here are some of the things that you can do with Huginn right now:

* 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 large spike.)
* Watch for air travel deals
* Follow your project names on Twitter and get updates when people mention them
* Scrape websites and receive emails when they change
* Compose digest emails about things you care about to be sent at specific times of the day
* Track counts of high frequency events and send an SMS within moments when they spike, such as the term "san francisco emergency"
* Watch public transit
* Run arbitrary JavaScript Agents on the server
* Track your location over time
* Create Amazon Mechanical Turk workflows as the inputs, or outputs, of agents.  ("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.")

Follow [@tectonic](https://twitter.com/tectonic) for updates as Huginn evolves, and join us in [our IRC channel](https://kiwiirc.com/client/irc.freenode.net/?nick=huginn-user|?#huginn) (\#huginn on Freenode) to discuss the project.

### We need your help!

## Getting Started

### Quick Start

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

* Copy `.env.example` to `.env` (`cp .env.example .env`) and edit `.env`, at least updating the `APP_SECRET_TOKEN` variable.
* Run `rake db:create`, `rake db:migrate`, and then `rake db:seed` to create a development MySQL database with some example Agents.
* Run `foreman start`, visit [http://localhost:3000/][localhost], and login with the username of `admin` and the password of `password`.
* Setup some Agents!
* Read the [wiki][wiki] for usage examples and to get started making new Agents.

Note: by default, emails are not sent in the `development` Rails environment, which is what you just setup.  If you'd like to enable emails when playing with Huginn locally, edit `config.action_mailer.perform_deliveries` in `config/environments/development.rb`.

If you need more detailed instructions, see the [Novice setup guide][novice-setup-guide].

## Deployment

Please see [the Huginn Wiki](https://github.com/cantino/huginn/wiki#deploying-huginn) for detailed deployment strategies for different providers.

### Optional Setup

#### Setup for private development

See [private development instructions](https://github.com/cantino/huginn/wiki/Private-development-instructions) on the wiki.

#### Enable the WeatherAgent

In order to use the WeatherAgent you need an [API key with Wunderground](http://www.wunderground.com/weather/api/). Signup for one and then change value of `api_key: your-key` in your seeded WeatherAgent.

#### Logging your location to the UserLocationAgent

You can use [Post Location](https://github.com/cantino/post_location) on your iPhone to post your location to an instance of the UserLocationAgent.  Make a new one to see instructions.

#### Enable DelayedJobWeb for handy delayed\_job monitoring and control

* Edit `config.ru`, uncomment the DelayedJobWeb section, and change the DelayedJobWeb username and password.
* Uncomment `match "/delayed_job" => DelayedJobWeb, :anchor => false` in `config/routes.rb`.
* Uncomment `gem "delayed_job_web"` in Gemfile and run `bundle`.

#### 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`.
