Possible to script jukebox?

[aereaux]

Hello,

I've been using mympd for a while and it works great. I have some scripts I use to listen to random songs that mostly go off sets of playlists instead of individual songs so that I listen to certain tracks (like classical music) in order. Is there some way to script the included jukebox so that I can include this behavior?

Also, looking a bit at the code, are there only a couple supported values of jukeboxUniqueTag, or can I set it to basically whatever I want?

Thanks.

The jukebox is fully scriptable as every function of myMPD. Look at the jsonrpc api documentation.

https://jcorporation.github.io/myMPD/references/api/

You can use the integrated lua scripting or call the api directly with e.g. curl.

The uniq tags of are not limited, but there is only one tag supported.

It looks like that is pretty limited in terms of what behavior I can change. I was hoping I could change it basically to choose a playlist from a certain directory to add. My (shell) script right now is basically:

find "$DIR" -type f -name '*.m3u' -printf "%P\n" | shuf -n $1 | mpc load

Right, the jukebox could not select a random playlists. It selects random songs from a playlist, but you can script this with lua inside myMPD.

This selects a random playlists and replaces the queue and starts playing.

-- get the first 2000 playlists
rc, raw_result = mympd_api_raw("MYMPD_API_PLAYLIST_LIST", json.encode({offset = 0, limit = 2000, searchstr = "", type = 0}))
result = json.decode(raw_result)
-- random number
math.randomseed(os.time())
number = math.random(0, #result.result.data)
-- get playlist by random number
playlist = result.result.data[number].uri
-- play the playlist
rc, raw_result = mympd_api_raw("MYMPD_API_QUEUE_REPLACE_PLAYLIST", json.encode({plist = playlist, play = true}))
-- return the playlist name
return "Playing" .. playlist

Thanks for the quick responses. I've added grouping tags to my library, and now I'm trying to use that. However, when I try to list the groupings I don't get anything (and same result using the API in a script). Any idea what's wrong?

$ curl -k https://localhost:4430/api/ --data '{"jsonrpc":"2.0","id":0,"method":"MYMPD_API_DATABASE_TAG_LIST","params":{"offset":0,"limit":2000,"searchstr":"((Album == \'Yellow House\'))","sortdesc":false,"tag":"Grouping"}}'
{"jsonrpc":"2.0","id":0,"result":{"method":"MYMPD_API_DATABASE_TAG_LIST","data":[],"totalEntities":0,"returnedEntities":0,"offset":0,"searchstr":"((Album == 'Yellow House'))","tag":"Grouping","pics":false}}

$ mpc list Grouping "((Album == 'Yellow House'))"

MYMPD_API_DATABASE_TAG_LIST does not support mpd filter expressions. searchstr is only matched against the tag values of Grouping. In the moment there is no API method to get the same results as with mpc.

Ah, that makes sense, thanks!
