Ruby Version

IMPORTANT!

Ruby version 1.9+ required. No support for 1.8.7 anymore, if you still on 1.8 consider using gem version 0.5.2 and bundle it like this:

gem 'musicbrainz', '0.5.2'

Installation

gem install musicbrainz

or add this line to your Gemfile

gem 'musicbrainz'

Configuration

MusicBrainz.configure do |c|
  # Application identity (required)
  c.app_name = "My Music App"
  c.app_version = "1.0"
  c.contact = "[email protected]"

  # Cache config (optional)
  c.cache_path = "/tmp/musicbrainz-cache"
  c.perform_caching = true

  # Querying config (optional)
  c.query_interval = 1.2 # seconds
  c.tries_limit = 2
end

Usage

require 'musicbrainz'

# Search for artists

# Use them like ActiveRecord models

Contributing

• Check out the latest master to make sure the feature hasn't been implemented or the bug hasn't been fixed yet
• Check out the issue tracker to make sure someone already hasn't requested it and/or contributed it
• Fork the project
• Start a feature/bugfix branch (IMPORTANT)
• Commit and push until you are happy with your contribution
• Make sure to add tests for it. This is important so I don't break it in a future version unintentionally.
• Please try not to mess with the Rakefile, version, or history. If you want to have your own version, or is otherwise necessary, that is fine, but please isolate to its own commit so I can cherry-pick around it.
