Zero Plugin
===========
The ``zero`` plugin allows you to null fields in files' metadata tags. Fields
can be nulled unconditionally or conditioned on a pattern match. For example,
the plugin can strip useless comments like "ripped by MyGreatRipper." This
plugin only affects files' tags ; the beets database is left unchanged.
To use the ``zero`` plugin, enable the plugin in your configuration
(see :ref:`using-plugins`).
Configuration
-------------
Available option :
- ``fields``: whitespace-separated list of fields to change. You can get the
list of available fields by running ``beet fields``. To conditionally filter
a field, use ``field: [regexp, regexp]`` to specify regular expressions.
For example::
zero:
fields: month day genre comments
comments: [EAC, LAME, from.+collection, 'ripped by']
genre: [rnb, 'power metal']
If a custom pattern is not defined for a given field, the field will be nulled
unconditionally.
Note that the plugin currently does not zero fields when importing "as-is".
