This is a very simple parser for Facebook Pages (a.k.a fan pages), using the Graph API. This gem was made in 2 hours for an experimental project, so many small fixes need to be made. You're welcome to make a pull request :)
Include the gem on your Gemfile:
gem 'facebook_page_parser'
Install it
bundle install
Simple example:
page = "http://www.facebook.com/pages/CAIXA-DE-IDEIAS/89888524723"
fb = FacebookPageParser::Parser.new(page)
fb.get["description"] #or any attribute you want from the API
Following the same example, to require a picture in a given type you could use:
thumbnail = fb.page + "/picture&type=small"
