Built on the web API in Spotify.jl.
This adds a Spotify-mode to Julia, extending what you can do with mouse clicks in the Spotify app. With a mode like this, we can read single keystrokes from the keyboard without pressing enter, and overwrite text output.
If you prefer the keyboard over a mouse, try these out!
You need to be running a Spotify player somewhere, on any device - we get the currently playing status over the web. But there is no background task checking if a track is finished. So press space to update the status line when a track is finished. return also re-prints the menu.
When authorization runs out, after an hour or so, re-enter the REPL-mode to re-apply!
Toggling unique ids on with i will print those together with the name of all things. Ids are useful if you want to make your own scripts, but also uglify the status line and selection menus. Ids are also useful when two tracks have the same name.
A context is a container the track is playing from. Different context types are printed with different colors.
In the figure above, we pressed c while playing from a playlist we own: "101-102spm", which has 32 tracks. The track also appears in one other playlist we own, "Barra Barra". This package focuses on managing playlists. For speed, it updates a local lookup table for those we own.
This is the current context type if you have clicked on an artist in Spotify's app and picked one of the top tracks. When in the artist context, pressing c will show all the tracks by the artist which appear in your owned playlists.
If you click on a track in an album, single or collection in Spotify's app, the context type is 'album'. In that case, pressing c would show some details about the album.
Pressing m will
- Show musician(s) details, including all associated genres (in the above case, 'ukulele')
- List all these musicians' tracks in your playlistst (Jake Shimabukuro is exceptional: He has separate Spotify's identities for Japan and elsewhere.).
- Let you jump to any of those tracks and contexts.
g for genres - shows musician details without further ado.
Pressing a is a quick way to get an overview of the current track.
Above the plots, there is a list of audio features. These are
single numbers charaterizing the whole of the current track. These can be used directly for ranking of tracks in a context (see o), even for multi-dimensional rankings and playlist statistics.
Below the plots, a metronome is updated with every beat. Use numbers keys 1-9 to seek to a position within the track (0 is currently buggy). The bottom left fraction is 'current bar' / 'current beat'.
The graphic plots show the basis for audio features, distributed over time. In the example track, 'Time signature (beats per bar)' is constant at four beats per bar, and is therefore not plotted.⠀
The 'Timbre' plot is too abstract for human humans, but 'Pitches' basically shows the melody (and the amount of drum noise).
Expand the REPL window and zoom out the text size! This will increase the horizontal resolution of plots.
The remaining menu choices are mainly made for pruning out the odd mistake in your playlists. Use sub-menus to pick criteria for ranking. Above each ranked list, barplots show the distribution of values.
These tools work for other context types than 'playlist', but will be slower because no local data is stored.
Beware when deleting tracks; we don't ask for confirmation there. You can always restore an old playlist version based on the returned snapshot id, but you would have to find out how yourself.
Good luck!
