This avoids some round-tripping problems with types (such as ScaledInt) that
are not represented in strings with 100% fidelity. It also makes the syntax
nicer when editing numbers and booleans: they no longer appear to be
needlessly surrounded by quotes in the YAML.
I hadn't quite realized before that the user could also change the *keys* to
be non-strings too! This also prevents against that by just reinterpreting
everything as strings.
* Revise the NotQuery syntax, replacing the '¬' character with '^'. Fix tests
to conform to this change, and cleanup the PARSE_QUERY_PART_REGEX.
* Modify parse_query_part() docstring to mention the negate parameter on the
returned tuple, and added an example.
* Add tests to NotQueryTest for testing the results of using queries with
negation.
* Fix issue on test_dbcore due to the modifications on the tuple returned by
parse_query_part (the number of elements was changed from 3 to 4).
* Update the negation query sintax so that the negation prefix ("-" or "¬") is
always the first part of a query, instead of after the ":" separator.
* Modify queryparse, so that the detection of the negation is done inside
parse_query_part() (using the modified PARSE_QUERY_PART_REGEX, and returning
the negation flag) instead of construct_query_part.
* Revert the prefixes dict on beets.library to the original dict (only one item,
with the RegexpQuery prefix).
* Modify NotQuery so it subclasses Query instead of MutableCollectionQuery.
* Update instances where NotQuery objects are created on tests and queryparse,
as NotQuery expects a single Query as a parameter to the constructor instead of
a list of Queries.
We now ask for a trinary edit/apply/cancel confirmation *after* showing the
updates. This lets you decide whether you're done based on a "preview" of the
changes and keep editing if they don't look right.
* 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.
* Update test for extra fields in edited yaml, allowing the user to add fields
while editing. Rename the test to test_single_edit_add_field to reflect its
purpose more accurately.
* Update unit tests in order to reflect the changes on the last refactor of
edit.py (patch edit.edit instead of EditPlugin.get_editor, revise stdin strings
to match current version, remove TODO on docstrings from malformed and invalid
yaml tests).
Removed three prompts:
1. The "really edit?" prompt. If you don't want to edit, you can just not make
any changes.
2. The "done?" loop. This seems unnecessary; we'll confirm afterward anyway.
3. The YAML checker. This removal could indeed make things inconvenient, since
your changes get thrown away if you make a YAML mistake. For the moment,
simplicity is taking priority.
