Missing Plugin
################
This plugin adds a new command, ``missing`` or ``miss``, which finds and lists
missing tracks for albums in your collection. Each album requires one network
call to album data source.
*******
Usage
*******
Add the ``missing`` plugin to your configuration (see :ref:`using-plugins`). The
``beet missing`` command fetches album information from the origin data source
and lists names of the **tracks** that are missing from your library.
It can also list the names of missing **albums** for each artist, although this
is limited to albums from the MusicBrainz data source only.
You can customize the output format, show missing counts instead of track
titles, or display the total number of missing entities across your entire
library:
::
-f FORMAT, --format=FORMAT
print with custom FORMAT
-c, --count count missing tracks per album
-t, --total count totals across the entire library
-a, --album show missing albums for artist instead of tracks for album
--release-type show only missing albums of specified release type.
You can provide this argument multiple times to
specify multiple release types to filter to. If not
provided, defaults to just the "album" release type.
…or by editing the corresponding configuration options.
.. warning::
Option ``-c`` is ignored when used with ``-a``, and ``--release-type`` is
ignored when not used with ``-a``. Valid release types can be shown by
running ``beet missing -h``.
***************
Configuration
***************
To configure the plugin, make a ``missing:`` section in your configuration file.
The available options are:
- **count**: Print a count of missing tracks per album, with the global
``format_album`` used for formatting. Default: ``no``.
- **total**: Print a single count of missing tracks in all albums. Default:
``no``.
Formatting
==========
- This plugin uses global formatting options from the main configuration; see
:ref:`format_item` and :ref:`format_album`:
- :ref:`format_item`: Used when listing missing tracks (default item format).
- :ref:`format_album`: Used when showing counts (``-c``) or missing albums
(``-a``).
Here's an example
::
format_album: $albumartist - $album
format_item: $artist - $album - $title
missing:
count: no
total: no
*****************
Template Fields
*****************
With this plugin enabled, the ``$missing`` template field expands to the number
of tracks missing from each album.
