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.
* 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.
Our built-in "diff"-like functionality is pretty good because it's aware of
beets' data structures and types. This makes it more legible, in my opinion,
than an ordinary textual diff. So for now, I'm making this the only option (in
the spirit of making the plugin as straightforward as humanly possible).
* Add tests for executing the command with album queries (-a), testing the edit
of album and albumartist fields.
* Revise invalid and malformed yaml tests so they return a failure instead of
an error.
* Modify existing tests in order to explicitely check for differences (or lack
of) in the items fields, with the intention to ensure that no unintended changes
slip through.
* Added tests for modifying a single item from a list of items, and for editing
the album field of the items (stub for discussing whether the actual album
should be updated, etc).
* Add tests for the edit plugin, including a helper for bypassing the manual
yaml editing. Tests are focused on "black-box" functionality, running the
command and making assertions on the changes made to the library.
