Makes the dispatch to the chosen backend simpler in the thumbnails
plugin. Given that ArtResizer is not only about resizing art anymore,
these methods fit there quite nicely.
- Adds a configuration that, when enabled, will append the style to genre
- Rationale is to have more verbose genres in genre tag of players that only support genre
This didn't cause any issues since we only use the shared instance
anyway, but logically it doesn't make a lot of sense for the backends
always using ArtResizer.shared (which they should be oblivious of).
Uses a custom assertion to have more detailed output (which should help
with getting an idea what the difference between expected and actual
lyrics is), and use `subTest` to clearly associate test failure to a
backend.
In addition, this strip parenthesis from the lyrics' words. That helps
with the currently failing Tekstowo test, but doesn't entirely fix it.
Requires Python 3.4 for subTest.
Test more combinations of tags that might initially be present and
expected tags. The R128 codepath and the case of having the wrong type
of tags wasn't really tested before.
Another incorrect py2 -> py3 translation. Since python 3 attached the
traceback to the exception, this should preserve the traceback without
needing to resort to sys.exc_info
This is an incorrect translation of a python 2 reraise to python 3.
With python 3, however, we can just rely on exception chaining to get
the traceback, so get rid of the complicated re-raising entirely, with
the additional benefit that the exception from the tear-down is also
shown.
When the delete_originals was set, beets would print the following, regardless
of the presence of the quiet parameter:
convert: Removing original file /path/to/file.ext
This commit ensures that the log is only printed when quiet is not present.
Unit test may fails when path to temprorary library contains `.`; to
garantue that bug wasn't here, it forces to use one more `.` inside path.
Fixes: https://github.com/beetbox/beets/issues/4151
remove interlacing by default when resizing/down-scaling, the
`deinterlace` option is to remove interlace when otherwise no processing
would have happened.
