NameError: global name '_' is not defined
for punctuation, normalization (merging similar looking characters into
the most common one), accents, and full conversion to ascii.
Functions and tests moved into separate files.
Although more comprehensive, the code should run faster because it
eliminates several loops (inc. a loop with two unicodedata references).
This is intended to form the basis of future PRs to:
a. Clean up (simplify) the file naming code
b. Provide script function(s) for cleaning individual tags / file name
parts
c. Add support for translation / transliteration plugins (which I think
make more sense than being included in Picard itself).
d. Support for converting Tags to ISO-8859-1 rather than ascii (since
that is what is supported by ID3 at least)
e. Possible additional options for allowing / preventing normalization,
possible reorganisation of options to centralise all encoding settings
onto one page rather than metadata, tags and file naming pages at
present (to be discussed).
We had a space-separated list of name,value tuples ("Album 0.5 Other 0.4"),
and two helper functions to load and save data in the correct format
(`load_release_type_scores` and `save_release_type_scores`).
Since option is converted to recently-introduced ListOption, data is now saved
as a list of tuples, eventually converted to dict when needed.
It simplifies code, and also prevents an issue if it comes we have a release group type
with a space in its name.
An upgrade hook was added to handle this change on Picard upgrade.
