Official GitHub Services Integration - You can set these up in your repo admin screen under Service Hooks

GitHub Services

How the services work

1. A post-receive background job is submitted when someone pushes their commits to GitHub
2. If the repository the commits belong to has any "Service Hooks" setup, the job makes a request to http://services-server/service_name/push with the following data:
   • params[:payload] containing all of the commit data (the same data you get using the API)
   • params[:data] containing the service data (username, password, room, etc)
3. Sinatra (github-services.rb) processes the request (twitters your data, says something in campfire, posts it to lighthouse, etc)
4. Rinse and repeat

Steps to contributing

1. Fork the project

2. Create a new file in /services/ called service_name.rb, using the following template:

   class Service::ServiceName < Service
     def receive_push
     end
   end

3. Vendor any external gems your code relies on, and make sure it is specified in the Gemfile.

4. Add documentation to docs/service_name (refer to the others for guidance)

5. Send a pull request from your fork to github/github-services

6. Once it's accepted we'll add any new necessary data fields to the GitHub front-end so people can start using your addition.

Patches including tests are encouraged

A huge thanks goes out to our many contributors!

Running the server locally

1. [sudo] gem install hpricot
2. git clone git://github.com/github/github-services.git
3. cd github-services
4. ruby github-services.rb

• Bugs in the code should be filed under the Issues tab
• Problems with the service hooks can be filed here

How to test your service

You can test your service in a ruby irb console:

1. Run rake console to start irb.

2. Instantiate your Service:

   svc = Service::MyService.new(:push,
     # Hash of configuration information.
     {'token' => 'abc'},
     # Hash of payload.
     {'blah' => 'payload!'})
   
   svc.receive_push

3. The third argument is optional if you just want to use the sample payload.

   svc = Service::MyService.new(:push,
     # Hash of configuration information.
     {'token' => 'abc'})
   
   svc.receive_push

You can also use this one-liner in the shell instead:

bundle exec ruby -r config/load.rb -r services/myservice.rb -e \
  "Service::MyService.new(:push, {'foo' => 'bar'}).receive_push"

You can also test your hook with the Sinatra web service:

1. Start the github-services Sinatra server with ruby github-services.rb. By default, it runs on port 8080.
2. Edit the docs/github_payload file as necessary to test your service. (Usually just editing the "data" values but leaving the "payload" alone.)
3. Send the docs/github_payload file to your service by calling: ./script/deliver_payload [service-name]
