Spotify Plugin
==============

The ``spotify`` plugin generates `Spotify`_ playlists from tracks in your library. Using the `Spotify Web API`_, any tracks that can be matched with a Spotify ID are returned, and the results can be either pasted in to a playlist or opened directly in the Spotify app.

.. _Spotify: https://www.spotify.com/
.. _Spotify Web API: https://developer.spotify.com/web-api/search-item/

Why Use This Plugin?
--------------------

* You're a Beets user and Spotify user already.
* You have playlists or albums you'd like to make available in Spotify from Beets without having to search for each artist/album/track.
* You want to check which tracks in your library are available on Spotify.

Basic Usage
-----------

First, enable the ``spotify`` plugin (see :ref:`using-plugins`).
Then, use the ``spotify`` command with a beets query::

    beet spotify [OPTIONS...] QUERY

Here's an example::

    $ beet spotify "In The Lonely Hour"
    Processing 14 tracks...
    http://open.spotify.com/track/19w0OHr8SiZzRhjpnjctJ4
    http://open.spotify.com/track/3PRLM4FzhplXfySa4B7bxS
    [...]

Command-line options include:

* ``-m MODE`` or ``--mode=MODE`` where ``MODE`` is either "list" or "open"
  controls whether to print out the playlist (for copying and pasting) or
  open it in the Spotify app. (See below.)
* ``--show-failures`` or ``-f``: List the tracks that did not match a Spotify
  ID.

Configuration
-------------

The default options should work as-is, but there are some options you can put
in config.yaml under the ``spotify:`` section:

- **mode**: One of the following:  

   - ``list``: Print out the playlist as a list of links. This list can then
     be pasted in to a new or existing Spotify playlist.
   - ``open``: This mode actually sends a link to your default browser with
     instructions to open Spotify with the playlist you created.  Until this
     has been tested on all platforms, it will remain optional.

  Default: ``list``.
- **region_filter**: A two-character country abbreviation, to limit results
  to that market.
  Default: None.
- **show_failures**: List each lookup that does not return a Spotify ID (and
  therefore cannot be added to a playlist).
  Default: ``no``.
- **tiebreak**: How to choose the track if there is more than one identical
  result. For example, there might be multiple releases of the same album.
  The options are ``popularity`` and ``first`` (to just choose the first match
  returned).
  Default: ``popularity``.
- **regex**: An array of regex transformations to perform on the
  track/album/artist fields before sending them to Spotify.  Can be useful for
  changing certain abbreviations, like ft. -> feat.  See the examples below.
  Default: None.

Here's an example::

    spotify:
        mode: open
        region_filter: US
        show_faiulres: on
        tiebreak: first

        regex: [
            {
                field: "albumartist", # Field in the item object to regex.
                search: "Something", # String to look for.
                replace: "Replaced" # Replacement value.
            },
            {
                field: "title",
                search: "Something Else",
                replace: "AlsoReplaced"
            }
        ]
