Hey guys,
I released the Ruby client lib. It generates Ruby objects for method calls, so you don't have to worry about parsing JSON or XML on your own.
Install with: sudo gem install spacer
The (rather sparse) documentation is at: http://spacer.rubyforge.org/
Use like:
@myspace = Spacer::Client.new(api_key, secret_key)
user = @myspace.user('3454354')
puts user.interests.music
puts user.photos.first.caption
I'll start a Google Group for questions/comments. Please submit test-driven patches to Rubyforge (http://rubyforge.org/projects/spacer/).
Keep in mind that this is super alpha software and no where near a 1.0. For example there is no error handling yet.
Enjoy!
