* Add support for user friendly "not" operator in queries without requiring to
use regular expressions, via adding NotQuery to beets.dbcore.query.
* Update the prefix list at library.parse_query_parts() and the query parsing
mechanisms in order to create a NotQuery when the prefix is found.
* Add two TestCases, NotQueryMatchTest as the negated version of MatchTest, and
the more generic NotQueryTest for testing the integration of the NotQuery with
the rest of the existing Query subclasses.
Detect path parts of a query with `PathQuery.is_path_query()` which
tests for `os.sep` presence AND query part existence.
Also fix a bug where "my_path/" would not get detected: colon absence would
make search for `os.sep` only happen in "my_path".
Fix#1385.
Test usqge of SQL's substr() with a UTF8 example. The ideal would be to
test with non-UTF8 code points, however it is impossible to perform such
a query: queries can only be unicode or utf8.
Places where InvalidQueryArgumentTypeError may be raised (i.e. all
current ones) may not know the query therefore it cannot be an
InvalidQueryError. The InvalidQueryArgumentTypeError is caught in
beets.library.Library._fetch() and an InvalidQueryError is then raised.
Improve #1290.
Replace previous InvalidQueryError with InvalidQueryArgumentTypeError
which extends the former as TypeError. However they lack context: the
query that caused the error.
Raise an InvalidQueryError when a shell-like expression cannot be parsed
by shlex.
Improve #1290.
Include import of __future__ features division, absolute_imports and
print_function everywhere. Don't add unicode_literals yet for it is
harder to convert.
Goal is smoothing the transition to python 3.
So far an invalid query won't be applied:
$ beet ls The Beatles year:196a
will be treaded as
$ beet ls The Beatles
With this commit it stops beets, returns 1 and produces
$ invalid query: u'196a' is not an int or a float
This applies to any querying and therefore on many command, plugins and
some configuration options.
Invalid queries exist on numeric fields and on regular expression usage.
Compile regular expression queries upon instantiation instead of upon
each match test.
The reporting can be improved (give more context). Fix#1219.
