This splits update_card() into separate undoable/non-undoable ops
like the change to notes in b4396b94abdeba3347d30025c5c0240d991006c9
It means that actions get a blanket 'Update Card' description - in the
future we'll probably want to either add specific actions to the backend,
or allow an enum or string to be passed in to describe the op.
Other changes:
- card.flush() can no longer be used to add new cards. Card creation
is only supposed to be done in response to changes in a note's fields,
and this functionality was only exposed because the card generation
hadn't been migrated to the backend at that point. As far as I'm aware,
only Arthur's "copy notes" add-on used this functionality, and that should
be an easy fix - when the new note is added, the associated cards will
be generated, and they can then be retrieved with note.cards()
- tidy ups/PEP8
- anki._backend stores the protobuf files and rsbackend.py code
- pylib modules import protobuf messages directly from the
_pb2 files, and explicitly export any will be returned or consumed
by public pylib functions, so that calling code can import from pylib
- the "rsbackend" no longer imports and re-exports protobuf messages
- pylib can just consume them directly.
- move errors to errors.py
Still todo:
- rsbridge
- finishing the work on rsbackend, and check what we need to add
back to the original file location to avoid breaking add-ons
- front/back/css shown in tabs
- front/back preview switchable; only one webview needs to be loaded
- dropdown to select cloze number in preview
- search box to search in front/back/css
- changes are now committed in bulk when closing the dialog,
and can be canceled
- it's not necessary to save the note to the database to preview it
- duplicate fields are now shown as duplicates in the top list
- redraw preview more quickly
- use + instead of _ when deduplicating names, as the latter is a
glob character
Saves having to serialize the note fields and q/a templates, which
is particularly a win when rendering question/answer in the browse
screen.
Also some work towards being able to preview notes without having to
commit them to the database.
- _renderQA() has moved to template.py:render_card()
- dropped QAData in favour of a properly typed dict
- render_card() returns a TemplateRenderOutput struct instead of a dict
- card_did_render now takes that output as the first arg, and can
mutate it
- TemplateRenderContext now stores the original card, so it can return
a card even in the add screen case
The old mungeFields and mungeQA hook have been removed as part of this
change. mungeQA can be replaced with the card_did_render hook.
In the mungeFields case, please switch to using field_filter instead.
We can now show replay buttons for the audio contained in {{FrontSide}}
without having to play it again when the answer is shown.
The template code now always defers FrontSide rendering, as it wasn't
a big saving, and meant the logic had to be implemented twice.
- the new API operates on AVTags so it can support TTS as well as
audio files
- added a simple "run for each file" implementation for mpv and mplayer.
- will need to test handling of unicode filenames on Windows
- the old mpv and mplayer code is currently not active
- the context exists for the lifecycle of one card's render,
and caches calls to things like .card() to avoid add-ons needing to
do their own cache management.
- add-ons can optionally add extra data to the context if they need
it across multiple filters
- removed card_will_render. the legacy hook is still available for
now
- card_did_render is now called only once, with both front and back
text
This allows us to add a docstring to .append() so users can see
the names of the arguments that are being passed, and means we
don't have to remember to prepend run_ when calling a hook.
- The front and back are rendered in one call now. If the front
side contains no custom filters, we can bake {{FrontSide}} into the
rear side. If it did contain custom filters, we return the partially
complete rear template instead, and the calling code can inject
the FrontSide in after it has been fully rendered.
- Instead of modifying "cloze" into something like "cq-2", the card
ordinal and whether we're rendering the question or answer are now
passed in to the rendering filters as context.
- The Rust code doesn't need to support filter names split on '-'
anymore.
- Drop the "Show" part of hint descriptions so i18n support can be
deferred.
- Ignore blank filter names caused by user using two colons instead
of one.
- Fixed hint field and text transposition.
