Songbird Recipe: Playlists

Here's a quick javascript+XPCOM recipe on how to get a list of the user's playlists in a songbird extension.

function getUserPlaylists() { var sLM = Components.classes["@songbirdnest.com/Songbird/library/Manager;1"] .getService(Components.interfaces.sbILibraryManager); var aLib = sLM.mainLibrary; var playlists = [aLib]; var pnames = []; var listener = { onEnumerationBegin: function() { }, onEnumerationEnd: function() { }, onEnumeratedItem: function(list, item) { if (pnames.indexOf(item.name)==-1){ // sometimes we get smart playlists multiple times playlists.push(item); pnames.push(item.name); } return Components.interfaces.sbIMediaListEnumerationListener.CONTINUE; } }; aLib.enumerateItemsByProperty("http://songbirdnest.com/data/1.0#isList", "1", listener ); return playlists; } function playPlaylist(plist,i){ // i == index of the song you want to play var gMM = Components.classes["@songbirdnest.com/Songbird/Mediacore/Manager;1"] .getService(Components.interfaces.sbIMediacoreManager); gMM.sequencer.playView(plist.createView(),i); }

Once you get your lists of playlists, you can start one playing with playPlaylist(plist,index) or check the user-visible names with plist.name.
