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 unchanged.
To use the plugin, enable it by including
zero in the
plugins line of
your configuration file. To configure the plugin, use a
zero: section in
your configuration file. Set
fields to the (whitespace-separated) list of
fields to change. You can get the list of available fields by running
fields. To conditionally filter a field, use
field: [regexp, regexp] to
specify regular expressions.
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”.
