This patch allows you to create playlists that are dynamically updated
every time you select one by running a simple SQL query on the
musicmetadata table. It allow you to, for example, create a playlist
that contains all the tracks by a particular artist, all your favourite
tracks, all the tracks from a genre etc. You can also create an order by
clause which allows you to order the tracks how you like and limit the number of tracks in a playlist. Playlists can be grouped together by category. You could for example create categories called 'By Artist', 'By Genre' etc. that way you don't get one big list of playlists but several playlist grouped together by a category. The patch adds a few demo smartplaylists to get you started.
At the moment you can only access the smartplaylists from the playback screen by pressing the 'MENU' key which brings up a popup menu. The top item 'Smart Playlists' takes you to the smart playlist selection dialog. The items below that allow you to quickly create a playlist that contains:- all tracks, all tracks by the currently playing artist, all tracks from the currently playing album, all tracks from the currently playing genre or all tracks from the currently playing year.
I won't describe all the dialogs in detail. If you have any questions then please just ask. I hope it is self explanatory!
I was waiting for the compilation artist patch to be applied to cvs before submitting this patch but has it seems things are starting to gear up towards the 0.17 release I thought it would be a good idea to get it into cvs so any problems could be ironed out before the release. I hope you don't mind Colin. I know your patch touches several of the same files as this patch.
I haven't been able to spend as much time on testing as I would have
liked but it seems to work OK for me. I think I have made all the query's
utf8 friendly. As always if anybody spots any problems please let me know and I will try to fix it.
One thing that is missing from the patch is support for the bool and date type fields. Which means you can't query the 'compilation' or 'last_played' fields which is no big loss. I will try and add them later.
I had to hand edit the patch slightly to remove some other stuff that
doesn't belong in this patch. I hope I haven't screwed the patch up in the process or removed something that I shouldn't.
