One of the first things that actually triggered my interest in Spotify was that although they did not have an official Linux client, they did seem to try and assure it worked well in Wine, even recommending using Wine to Linux users, with this page dedicated to assuring the experience is complete as possible (although it generally works out the box).

One of the most useful parts of that page is where they provide a nice, simple script to allow native Linux applications to call the Spotify client running under Wine with Spotify’s URIs that are used to share playlists, tracks, etc. They also provide instructions on how to get Firefox and Opera to call this script for those URIs (for example using an entry on about:config in Firefox).

This works great, until you try to use the URIs outside Firefox or Opera, say in Pidgin or a Chromium alpha, neither of which appear to provide their own methods for supporting custom URIs, instead they depend on either Gnome or ‘xdg-open’ (which in turn can ask Gnome). So I thought it might be a good idea simply to tell Gnome to use the script, and let everything else depend on Gnome; sadly I could find no graphical way of doing this, but after a bit of searching, I found this page, which revealed it was a simple as adding a few keys to GConf. So I adapted to method for the Spotify URI and script, and sure enough it works fine (certainly in both Chromium and Pidgin, on Ubuntu 9.04).

Below are the normal commands need to create aforementioned script:

echo '#!/bin/sh' > ~/.browser2spotify
echo 'exec wine "C:\Program Files\Spotify\spotify.exe" /uri "$@"' >> ~/.browser2spotify
chmod 755 ~/.browser2spotify

And here are the commands for adding the GConf keys, but be careful, tidles and variables didn’t appear to work here, so you will need to manually modify the address in the first command to reflect your username:

gconftool-2 -t string -s /desktop/gnome/url-handlers/spotify/command "/home/<your username here>/.browser2spotify %s"
gconftool-2 -s /desktop/gnome/url-handlers/spotify/needs_terminal false -t bool
gconftool-2 -s /desktop/gnome/url-handlers/spotify/enabled true -t bool

Fingers crossed, all applications that call on Gnome or ‘xdg-open’ for unknown URIs (such as the aforementioned Pidgin and Chromium), should now be able to call Spotify; in fact, Firefox too calls either Gnome or ‘xdg-open’, so this method can suffice for Firefox too.

Update 1st May 2010 regarding other points on Spotify in Wine:

  • As of the current Wine release, the new Facebook social function works, but you must first associate (‘connect’) your Facebook account by running Spotify on Windows, as the login page only half works under Wine at the moment.
  • This guide is great for doing the reverse: allowing apps running in Wine –  like Spotify – to call your native browser (Firefox, Chromium etc.) – just one note though: on the second step, you should only need ‘xdg-open’ as the string value. (I wonder why Wine doesn’t call xdg-open by default)
