Looking up Providers ==================== ``plyr.PROVIDERS`` contains a nested dict modelling all compiled in fetchers and providers. .. code-block:: python 'albumlist': { # The name of this fetcher 'required' : ('artist'), # A list of required properties 'optional' : (), # A list of properties that are optional 'provider' : [{ # A list of providers this fetcher can use 'key' : 'm', # one-char identifier of this provider (rarely used) 'name' : 'musicbrainz', # Full name of this provider 'quality' : 95, # subjective quality (0/100) 'speed' : 95 # subjective speed (0/100) }, { ... next_provider ... }] }, 'lyrics': { ... next_fetcher ... } You can use this for example to get a list of all fetchers: :: list(plyr.PROVIDERS.keys()) You get the idea. Use ``itertools`` and friends to get the data you want in a oneliner. .. note:: This dictionary gets built on import. Different version of libglyr may deliver different providers.
