Spotify.el

Control Spotify app from within Emacs.

Spotify.el is a collection of extensions that allows you to control the Spotify application from within your favorite text editor.

Note: This is very alpha software, and it works only in Mac OS X and Linux.

Features

• Spotify client integration for GNU/Linux (via D-Bus) and OS X (via AppleScript)
• Communicates with the Spotify API via Oauth2
• Displays the current track in mode line
• Create playlists (public or private)
• Browse the Spotify featured playlists, your own playlists, and their tracks
• Search for tracks and playlists that match the given keywords
• Easily control basic Spotify player features like, play/pause, previous, next, shuffle, and repeat with the Spotify Remote minor mode

Installation

First, make sure your system satisfies the given dependencies:

• Emacs 24.4+
• Python 2.7+ (needed for the Oauth2 callback server)

To manually install spotify.el, just clone this project somewhere in your disk, add that directory in the load-path, and require the spotify module:

(add-to-list 'load-path "<spotify.el-dir>")
(require 'spotify)

;; Settings
(setq spotify-oauth2-client-secret "<spotify-app-client-secret>")
(setq spotify-oauth2-client-id "<spotify-app-client-id>")

Or if you use el-get:

(add-to-list
  'el-get-sources
  '(:name spotify.el
          :type github
          :pkgname "danielfm/spotify.el"
          :description "Control the Spotify app from within Emacs"
          :url "https://github.com/danielfm/spotify.el"
          :after (progn
                  (setq spotify-oauth2-client-secret "<spotify-app-client-secret>")
                  (setq spotify-oauth2-client-id "<spotify-app-client-id>"))))

In order to get the the client ID and client secret, you need to create a Spotify app, specifying http://localhost:8591/ as the redirect URI.

Creating The Spotify App

Go to Create an Application and give your application a name and a description:

At this point, the client ID and the client secret is already available, so set those values to spotify-oauth2-client-id and spotify-oauth2-client-secret, respectively.

Then, scroll down a little bit, type http://localhost:8591/ as the Redirect URI for the application, and click Add:

Finally, scroll to the end of the page and hit Save.

Usage

Starting A New Session

In order to connect with the Spotify API and refresh the access token, run M-x spotify-connect. This will start the Oauth2 authentication and authorization workflow.

You may be asked to type a password since the tokens are securely stored as an encrypted file in the local filesystem. After you enter your credentials and authorizes the app, you should see a greeting message in the echo area.

To disconnect, run M-x spotify-disconnect.

Searching For Tracks

To search for tracks, run M-x spotify-track-search and type in your query. The results will be displayed in a separate buffer with the following key bindings:

Key	Description
l	Loads the next page of results (pagination)
g	Clears the results and reloads the first page of results
RET	Plays the track under the cursor in the context of its album

The resulting buffer loads the spotify-remote-mode by default.

Tip: In order to customize the number of items fetched per page, just change the variable spotify-api-search-limit:

;; Do not use values larger than 50 for better compatibility across endpoints
(setq spotify-api-search-limit 50)

Playing a Spotify URI

To ask the Spotify client to play a resource by URI, run M-x spotify-play-uri and enter the resource URI.

Creating Playlists

To create new playlists, run M-x spotify-create-playlist and follow the prompts.

Currently it's not possible to add tracks to a playlist you own, or to remove tracks from them.

Searching For Playlists

To return the playlists for the current user, run M-x spotify-my-playlists, or M-x spotify-user-playlists to list the public playlists for some given user. To search playlists that match the given search criteria, run M-x spotify-playlist-search CRITERIA. Also, run M-x spotify-featured-playlists in order to browse the featured playlists from Spotify en_US.

Change the following variables in order to customize the locale and region for the featuerd playlists endpoint:

;; Spanish (Mexico)
(setq spotify-api-locale "es_MX")
(setq spotify-api-country "MX")

All these commands will display results in a separate buffer with the following key bindings:

Key	Description
l	Loads the next page of results (pagination)
g	Clears the results and reloads the first page of results
f	Follows the playlist under the cursor
u	Unfollows the playlist under the cursor
t	Lists the tracks of the playlist under the cursor
RET	Plays the playlist under the cursor from the beginning (*)

Once you opened the list of tracks of a playlist, you get the following key bindings in the resulting buffer:

Key	Description
l	Loads the next page of results (pagination)
g	Clears the results and reloads the first page of results
f	Follows the current playlist
u	Unfollows the current playlist
RET	Plays the track under the cursor in the context of the playlist (*)
M-RET	Plays the track under the cursor in the context of its album

Both buffers load the spotify-remote-mode by default.

(*) No proper support for this in Spotify client for GNU/Linux

Remote Minor Mode

Whenever you enable the spotify-remote-mode you get the following key bindings:

Key	Function	Description
M-p M-s	spotify-toggle-shuffle	Turn shuffle on/off (*)
M-p M-r	spotify-toggle-repeat	Turn repeat on/off (*)
M-p M-p	spotify-toggle-play	Play/pause
M-p M-f	spotify-next-track	Next track
M-p M-b	spotify-previous-track	Previous track

This is particularly useful for those using keyboards without media keys.

Also, the current song being played by the Spotify client is displayed at the mode line along with the player status (playing, paused). The interval in which the mode line is updated can be configured via the spotify-mode-line-refresh-interval variable:

;; Updates the mode line every second (set to 0 to disable this feature)
(setq spotify-mode-line-refresh-interval 1)

(*) No proper support for this in Spotify client for GNU/Linux

Customizing The Mode Line

The information displayed in the mode line can be customized by setting the desired format in spotify-mode-line-format. The following placeholders are supported:

Symbol	Description	Example
%u	Track URI	spotify:track:<id>
%a	Artist name	Pink Floyd
%at	Artist name (truncated)	Pink Floyd
%t	Track name	Us and Them
%tt	Track name (truncated)	Us and Them
%n	Track #	7
%d	Track disc #	1
%s	Player state (*)	playing, paused, stopped
%l	Track duration, in minutes	7:49
%p	Current player position, in minutes (*)	2:23

The default format is "%at - %tt [%l]".

The number of characters to be shown in truncated fields can be configured via the spotify-mode-line-truncate-length variable.

(setq spotify-mode-line-truncate-length 10) ; default: 15

(*) No proper support for this in Spotify client for GNU/Linux

Global Remote Mode

This mode can be enabled globally by running M-x global-spotify-remote-mode.
