The list_format_album and list_format_item options now *actually* affect the
display in commands other than "beet list". This replaces the -f/--format flags
-- if any users want to control this on the command line, we can reconsider this
decision.
Note that this involved passing around a "config" object, which we previously
haven't done. This seems a little bit messy, but configuration is about to
change entirely to be more like this style -- so this isn't a huge liability.
This version of the (renamed) _print_obj function uses introspection to
determine whether we're printing an Album or an Item. It's like function
overloading for Python! 😁
This has been a long time coming, but we now finally keep track of ReplayGain
values in the database. This is an intermediate step toward a refactoring of the
RG plugin; at the moment, these values are not actually saved!
We now always calculate album gain when importing an album. This is "free" (no
performance cost) now and players are free to ignore the setting if they so
choose.
This ensures accurate album-level data. It also fixes a problem with the old way
of doing things where the MediaFiles and tool results would become misaligned if
a subset of the tracks needed recalculation.
Invocations of the mp3gain/aacgain commands are now wrapped in a centralized
function that takes care of output capture and error handling. This avoids code
duplication for the various sites at which the tool needs to be invoked.
This change also avoids unintentionally modifying tags via the command-line
tool. The "-s s" option makes the tool *just* calculate RG values rather than
toying with tags at all.
This is fixed by allowing MediaFiles to convert strings to integers on
assignment. An eventual complete fix will perform these type conversions in the
Item interface.
Eliminate the __subclasses__ trick for finding all plugins. Now we explicitly
look in each plugin module for a plugin class. This allows us to import plugin
modules with unintentionally loading them. This lets us reuse the image
embedding machinery without copypasta.
