This repository contains two gems:

* `diaspora_federation` provides the functionality for de-/serialization and de-/encryption of Entities in the protocols used for communication among the various installations of diaspora\*.
* `diaspora_federation-rails` is a rails engine that adds the diaspora\* federation protocol to a rails app.

## Usage

Add the gem to your ```Gemfile```:

```ruby
gem "diaspora_federation-rails"
```

Mount the routes in your ```config/routes.rb```:

```ruby
mount DiasporaFederation::Engine => "/"
```

Configure the engine in ```config/initializers/diaspora_federation.rb```:

```ruby
DiasporaFederation.configure do |config|
  # the pod url
  config.server_uri = URI("http://localhost:3000")

  # ... other settings

  config.define_callbacks do
    on :fetch_person_for_webfinger do |diaspora_id|
      person = Person.find_local_by_diaspora_id(diaspora_id)
      if person
        DiasporaFederation::Discovery::WebFinger.new(
          # ... copy person attributes to WebFinger object
        )
      end
    end

    on :fetch_person_for_hcard do |guid|
      # ... fetch hcard information
    end

    # ... other callbacks
  end
end
```
