Previously, there was just an "artist sort name" field -- now there's a
corresponding sort name for both track artists and album artists. I also made
the names shorter (artist_sort and albumartist_sort).
Generates disambiguating strings to distinguish albums from one another. To be
used as the basis for a simpler path field, $unique, as a default disambiguator.
Using a class wrapper allows additional context to be provided to the functions.
Namely, we can now provide the Item itself to the function, so %foo{} could
conceivably do something useful even without arguments. This will be used for
the upcoming %unique function.
Based on the "remove_duplicates" flag on ImportTask, the apply_choices coroutine
now looks for duplicates (using an extended version of the _duplicate_check
functions) and removes items from the library. It also *deletes* files
associated with those items when they are located inside the beets library
directory. Files outside of the directory are left on disk (but their DB entry
is still removed). This should "do the right thing" in most cases -- again, this
is something we can add a config option for if it comes up.
"Skip" and "keep both" work already, but "remove old" does not. It sets a flag
on the import task object; this flag should then be read by the apply_choices
coroutine, where appropriate action should be taken as part of the same
transaction that adds stuff to the DB.
Unresolved questions:
- Should old files be deleted? (How is this decided? Based on config parameters,
or with another prompt option?)
- Logging details.
- Folder naming. If I have two albums with the same name, I want them in
different directories.
- Quiet mode. Currently, there are no checks -- the prompt should not be made in
quiet mode. (In that case, what should it do?)
