FUSE file system for Spotify
The aim of this project is to provide a synthethic file system
as an interface towards Spotify. That includes, for example, being able
to check the state of your session by doing:
$ cat /home/alofgren/spotifile/connection
logged in

Browsing!
$ cd /home/alofgren/spotifile/playlists/meta/That\ Handsome\ Devil
$ ls
lrwxrwxrwx 0 alofgren root 56 Jul 23 13:45 $=♡ -> ../../browse/tracks/spotify:track:3idPftQBuIvi0Mbpz7UUcc

and so forth.

Basic requirements

A Spotify Premium account

Installation
Arch Linux
A PKGBUILD for the latest released version is available in the AUR.
Installing from source
To install spotifile from source, do the following
$ git clone git@github.com:catharsis/spotifile.git spotifile && cd spotifile
$ autoreconf -si
$ ./configure && make && make check && make install
Make sure you have all the required dependencies installed, or the ./configure step will likely complain loudly.
Quick start
The easiest way to get started with spotifile is to create a mountpoint somewhere (say, mkdir /tmp/spotifile) and run it like so ./spotifile -o username=spotify_username -o password=spotify_password /tmp/spotifile. However, that's not recommendable since it'll leave your Spotify credentials in the open for anyone else with access to your machine. Instead, most users should opt to create a configuration file ~/.config/spotifile/spotifile.conf, containing the credentials as such;
[spotify]
username=myUsername
password=myPassword

Depending on your situation, it is likely a good idea to set as restrictive permissions on the file as possible - it does contain sensitive data after all!
chmod 600 ~/.config/spotifile/spotifile.conf


NOTE: For a full listing of supported configuration options, see Configuration options.

Now, you can leave out the credentials from the command line;
./spotifile /tmp/spotifile

If everything goes as expected, you should now be able to cd to /tmp/spotifile, and check your connection status like this;
$ cd /tmp/spotifile
$ cat connection
logged in

To unmount the spotifile, simply run fusermount -u -z /tmp/spotifile.
Usage
Before all else, let's consider the directory structure of a running spotifile instance, and briefly discuss its contents:
$ ls -AlF
total 0
dr-x------ 0 alofgren root 0 Aug  7 09:59 browse/
dr-x------ 0 alofgren root 0 Aug  7 09:59 playlists/
dr-x------ 0 alofgren root 0 Aug  7 09:59 search/
-r--r----- 0 alofgren root 0 Aug  7 09:59 connection

In its current state, the root directory is pretty simple. It contains three directories, browse, playlists and search as well as a file connection which contains a textual description of the current state of your Spotify connection. The main entrypoint in spotifile to your Spotify data is through the playlists directory, which in turn contains two subdirectories meta and music. As you might expect, listing the contents of these directories will show you your familiar playlists. For me, that looks something like:
$ ls -AlF playlists/meta/
total 0
dr-x------ 0 alofgren root 0 Aug  7 10:00 .357 String Band /
dr-x------ 0 alofgren root 0 Aug  7 10:00 3 Inches of Blood/
dr-x------ 0 alofgren root 0 Aug  7 10:00 Alaskan Fishermen – Alaskan Fishermen/
dr-x------ 0 alofgren root 0 Aug  7 10:00 Antic Clay/
dr-x------ 0 alofgren root 0 Aug  7 10:00 Arsonists/
dr-x------ 0 alofgren root 0 Aug  7 10:00 At The Gates — Slaughter Of The Soul/
dr-x------ 0 alofgren root 0 Aug  7 10:00 Bathory/
dr-x------ 0 alofgren root 0 Aug  7 10:00 Behemoth/
dr-x------ 0 alofgren root 0 Aug  7 10:00 Blandat/
dr-x------ 0 alofgren root 0 Aug  7 10:00 Blaze Foley/
dr-x------ 0 alofgren root 0 Aug  7 10:00 Brown Bird/
dr-x------ 0 alofgren root 0 Aug  7 10:00 Burzum — Filosofem/
dr-x------ 0 alofgren root 0 Aug  7 10:00 Candlemass - Epicus Doomicus Metallicus/
# ... snip ...

For the music directory, which exists to make playback more convenient, each track is represented by a .wav file:
$ ls -AlF playlists/music/Arsonists/
total 0
-r--r----- 0 alofgren root 0 Jun 20  2011 00 - Intro.wav
-r--r----- 0 alofgren root 0 Jun 20  2011 01 - Backdraft.wav
-r--r----- 0 alofgren root 0 Jun 20  2011 02 - Shit Ain’t Sweet.wav
-r--r----- 0 alofgren root 0 Jun 20  2011 03 - Pyromaniax.wav
# ... snip ...

For the meta directory, each of its subdirectories in turn contain a collection of symlinks - one for each track in the playlist - pointing to the respective track directories in the browse directory. For example:
$ ls -AlF playlists/meta/Arsonists/
total 0
lrwxrwxrwx 0 alofgren root 56 Jun 20  2011 Alive -> ../../browse/tracks/spotify:track:5LEz8sfYIneF9la9icV9G0/
lrwxrwxrwx 0 alofgren root 56 Jun 20  2011 Backdraft -> ../../browse/tracks/spotify:track:1iqvZV4BcMpV81WVJBuBTw/
lrwxrwxrwx 0 alofgren root 56 Jun 20  2011 Blaze -> ../../browse/tracks/spotify:track:247py70aNT1jbDmnZGj3wL/
# ... snip ...

The targets of these links are created lazily, meaning that they are materialized only as something referring to them is inspected by the user, such as the symlinks above. As you might've already guessed - or observed, if you've strayed from the beaten path of this guide - this means that in a newly started spotifile instance, the browse directory only contains three empty directories:
$ tree browse
browse
├── albums
├── artists
└── tracks

3 directories, 0 files

This pattern of lazy creation is repeated throughout spotifile, for all main "objects" (currently artists, albums, and tracks). Speaking of which, let's inspect one of these browse directories:
$ $ ls -AlF browse/tracks/spotify:track:0xAyc8r3C1BNQzzDMKbOkw
total 0
dr-x------ 0 alofgren root 0 Aug  7 10:19 artists/
-r--r----- 0 alofgren root 0 Aug  7 10:19 autolinked
-r--r----- 0 alofgren root 0 Aug  7 10:19 disc
-r--r----- 0 alofgren root 0 Aug  7 10:19 duration
-r--r----- 0 alofgren root 0 Aug  7 10:19 index
-r--r----- 0 alofgren root 0 Aug  7 10:19 local
-r--r----- 0 alofgren root 0 Aug  7 10:19 name
-r--r----- 0 alofgren root 0 Aug  7 10:19 offlinestatus
-r--r----- 0 alofgren root 0 Aug  7 10:19 popularity
-r--r----- 0 alofgren root 0 Aug  7 10:19 starred
-r--r----- 0 alofgren root 0 Aug  7 10:19 track.wav

First and foremost, the name of the directory is a URI, which uniquely identifies the resource the directory contains. If you've ever shared tracks with other Spotify users, you've likely seen one before. Most of the files in the directory are (or should be) self-explanatory. The duration file, for example, contains the number of milliseconds the track lasts, and the contents of the starred track indicate whether the track is "starred" or not.
The track.wav file is the actual music (if it's a music track we're looking at, and not an audiobook, or something), and should be playable by most of the music players on your system.
The artists directory contains links to all the artists performing on this track:
ls -AlF browse/tracks/spotify:track:0xAyc8r3C1BNQzzDMKbOkw/artists
total 0
lrwxrwxrwx 0 alofgren root 54 Aug  7 10:28 Arsonists -> ../../../artists/spotify:artist:4VQ9fD75w7JlKZDIZKtpdf/

Looking inside of that directory, we see more information on the artist:
ls -AlF browse/tracks/spotify:track:0xAyc8r3C1BNQzzDMKbOkw/artists/Arsonists/
total 0
dr-x------ 0 alofgren root 0 Aug  7 10:28 albums/
dr-x------ 0 alofgren root 0 Aug  7 10:28 portraits/
-r--r----- 0 alofgren root 0 Aug  7 10:28 biography
-r--r----- 0 alofgren root 0 Aug  7 10:28 name

As mentioned earlier, the root directory contains a search directory. Unsuprisingly, this directory can be used to perform searches. A search is initiated by creating a new directory inside the search directory, like so:


NOTE: search is still in a somewhat experimental state, which is why it is a bit more rudimentary in its implementation than the browse and playlists directories.

As you might have guessed, the name of the created directory also acts as the query. The created directory will asynchronously be populated with the results for the query:
ls search/Trogdor/
The Bearded Bard - Trogdor The Burninator.wav

Currently, a query is hard limited to 100 search results. It is also only possible to search for tracks, at the moment.
And that's the whole tour for now!

Contributing
User interaction & engagement is thoroughly encouraged! spotifile is still in active development and your feedback is very likely to impact the future direction of the project.
Please report issues, feature requests and general feedback in the GitHub issue tracker. Bug requests should preferrably include as detailed steps to reproduce as you can manage (for extra credit, try to find a minimal test case that reproduces the bug). Please also include the output from spotifile -d <mountpoint> when reporting bugs, as it makes tracking them down that much easier.
Code contributions are of course very welcome, but I'd appreciate it if you'd go through the trouble of opening an issue or shoot me an e-mail before you start hacking so that we may discuss the change before any code is written. Needless to say, this doesn't necessarily apply to trivial fixes (like typo corrections) or obvious bug fixes (like segfaults). If you have a patch that you think would be neat to include, either open a pull request on GitHub, or send me a patch-mail directly.
Oh dear, why?
For fun, mostly. But also because I've been looking for a media playing solution that is both scriptable and ties into my otherwise somewhat minimalistic desktop environment nicely. I think this approach is not as crazy as it might initially sound for those purposes. It's worth a shot at least, yes?
