- clear_unused_tags() is now undoable, and returns the number of removed
notes
- add a new mw.query_op() helper for immutable queries
- decouple "freeze/unfreeze ui state" hooks from the "interface update
required" hook, so that the former is fired even on error, and can be
made re-entrant
- use a 'block_updates' flag in Python, instead of setUpdatesEnabled(),
as the latter has the side-effect of preventing child windows like
tooltips from appearing, and forces a full redrawn when updates are
enabled again. The new behaviour leads to the card list blanking out
when a long-running op is running, but in the future if we cache the
cell values we can just display them from the cache instead.
- we were indiscriminately saving the note with saveNow(), due to the
call to saveTags(). Changed so that it only saves when the tags field
is focused.
- drain the "on_done" queue on main before launching a new background
task, to lower the chances of something in on_done making a small query
to the DB and hanging until a long op finishes
- the duplicate check in the editor was executed after the webview loads,
leading to it hanging until the sidebar finishes loading. Run it at
set_note() time instead, so that the editor loads first.
- don't throw an error when a long-running op started with with_progress()
finishes after the window it was launched from has closed
- don't throw an error when the browser is closed before the sidebar
has finished loading
'card modified' covers the common case where we need to rebuild the
study queue, but is also set when changing the card flags. We want to
avoid a queue rebuild in that case, as it causes UI flicker, and may
result in a different card being shown. Note marking doesn't trigger
a queue build, but still causes flicker, and may return the user back
to the front side when they were looking at the answer.
I still think entity-based change tracking is the simplest in the
common case, but to solve the above, I've introduced an enum describing
the last operation that was taken. This currently is not trying to list
out all possible operations, and just describes the ones we want to
special-case.
Other changes:
- Fire the old 'state_did_reset' hook after an operation is performed,
so legacy code can refresh itself after an operation is performed.
- Fire the new `operation_did_execute` hook when mw.reset() is called,
so that as the UI is updated to the use the new hook, it will still
be able to refresh after legacy code calls mw.reset()
- Update the deck browser, overview and review screens to listen to
the new hook, instead of relying on the main window to call moveToState()
- Add a 'set flag' backend action, so we can distinguish it from a
normal card update.
- Drop the separate added/modified entries in the change list in
favour of a single entry per entity.
- Add typing to mw.state
- Tweak perform_op()
- Convert a few more actions to use perform_op()
Up until now, we've been forcing a new search whenever reset is called.
The primary reason was that the card list display routines did not expect
a card or note to have been removed. By updating the model to show
"(deleted)" when a card or note is missing, we no longer have to repeat
the search.
This has a few advantages:
- Searches, especially complex ones, can be slow to execute. When we
perform them after every operation like a delete, it can make Anki feel
sluggish.
- The fact that notes have been deleted becomes more obvious - some users
found it easy to miss the "deleted" pop-up in the past.
This change does not just affect deletions, as many other operations
trigger a reset as well. In the past, when using 'set due date' in the
review screen for example, it caused an ugly flicker in the browser screen,
and could be slow when the current search couldn't be quickly redone.
The disadvantage of this approach is that the displayed content may
not reflect the specified search, which has the potential to be confusing.
But if that turns out to be a problem, it could be (partly) alleviated by
displaying a refresh button next to the search bar when the search may
need to be refreshed.
Feedback welcome!
Work in progress - still to do:
- renames appear as 'Update Deck' - easiest way to solve it would
be to have a separate backend method for renames
- drag&drop of decks not yet undoable
- since the undo status is updated after the backend method ends,
the older checkpoint() calls need to be replaced with an
update_undo_status() at the end of the call - if we just remove the
checkpoint, then the menu doesn't get updated
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
- note.flush() behaves like before, as otherwise actions or add-ons
that perform bulk flushing would end up creating an undo entry for
each note
- added col.update_note() to opt in to the new behaviour
- tidy up the names of some related routines
- transact() now automatically clears card queues unless an op
opts-out (and currently only AnswerCard does). This means there's no
risk of forgetting to clear the queues in an operation, or when undoing/
redoing
- CollectionOp->UndoableOp
- clear queues when redoing "answer card", instead of clearing redo
when clearing queues
- Since we need to show this to new users until AnkiDroid is updated,
use a wording that doesn't seem so out of place to new users.
- Avoid mentioning syncing, since the user may not sync, and the
modSchema() call will allow the user to confirm anyway.
- Let the user know they can change their mind about AnkiDroid by
visiting the preferences.
- Rework V2 upgrade so that it no longer resets cards in learning,
or empties filtered decks.
- V1 users will receive a message at the top of the deck list
encouraging them to upgrade, and they can upgrade directly from that
screen.
- The setting in the preferences screen has been removed, so users
will need to use an older Anki version if they wish to switch back to
V1.
- Prevent V2 exports with scheduling from being importable into a V1
collection - the code was previously allowing this when it shouldn't
have been.
- New collections still default to v1 at the moment.
Also add helper to get map of decks and deck configs, as there were
a few places in the codebase where that was required.
'Current deck' has moved, and by removing 'due tomorrow', we can drop
the 'today' suffix on the rest of the items.
The keys of the existing translations have not been changed, so
existing translations will not break, but will need to be manually
updated to make them shorter.
The old rescheduling dialog's two options have been split into two
separate menu items, "Forget", and "Set Due Date"
For cards that are not review cards, "Set Due Date" behaves like the
old reschedule option, changing the cards into a review card, and
and setting both the interval and due date to the provided number of
days.
When "Set Due Date" is applied to a review card, it no longer resets
the card's interval. Instead, it looks at how much the provided number
of days will change the original interval, and adjusts the interval by
that amount, so that cards that are answered earlier receive a smaller
next interval, and cards that are answered after a longer delay receive
a bonus.
For example, imagine a card was answered on day 5, and given an interval
of 10 days, so it has a due date of day 15.
- if on day 10 the due date is changed to day 12 (today+2), the card
is being scheduled 3 days earlier than it was supposed to be, so the
interval will be adjusted to 7 days.
- and if on day 10 the due date is changed to day 20, the interval will
be changed from 10 days to 15 days.
There is no separate option to reset the interval of a review card, but
it can be accomplished by forgetting the card(s), and then setting the
desired due date.
Other notes:
- Added the action to the review screen as well.
- Set the shortcut to Ctrl+Shift+D, and changed the existing Delete
Tags shortcut to Ctrl+Alt+Shift+A.
- Closes#976
- Added helper to apply arbitrary colour to an icon.
- Fix#979 - low res icons in night mode.
- The icons and colours are not perfect - please feel free to send
through a PR if you can improve them.
- Convert colors dictionary into module consts, so we can
use code completion.
- Added "Edited Today" and "Due Tomorrow"
- Rename camelCase attribute to snake_case and tweak the wording
of some enum constants. We've already broken compatibility with the
major sidebar add-ons, so we may as well make these changes while we
can.
- Removed Filter button. Currently there is no exposed way to toggle
the Sidebar off - wonder if we still need it?
There's a 'whole collection' link in the top left, so the latter part
is probably not required, and shortening this will bring it into line
with the sidebar placeholder. Open to suggestions on the wording,
just think it's probably best to keep it short.
Also remove unused string.
- Remove _searchPrompt.
- Add placeholder prompt.
- Move search for current card from browser to caller. (Thus, support
current card search even with opened browser.)
The original reason for the catch-all message was users with bad
data such as decimal intervals, but those get automatically coerced
these days. The common case should now be invalid search strings, which
we can show verbatim.
The majority of the error checking can now be delegated to routines
like parse_f32(), parse_negative_i32() and so on, instead of creating
specific error messages for each type.
- use markdown instead of HTML, to make editing and translating easier
- use a shared prefix
- a few very minor wording tweaks
- we don't need to translate undocumented command errors
- share a string for positive number of days
- share a string for invalid property and state arguments, and avoid
listing them out

More than {{ is acceptable to start a tag, which means that `{{{Foo}}` won't be interpreted as "the content of `Foo`"
and should be rejected. For the sake of clarity and parsing, I suspect that those symbol should be rejected elsewhere
too.
Similary `{{Foo}}}` won't be interpreted as "Show the content of field `Foo}`" even if this field exists, so it's better
to reject `}`. It's clearly necessary to reject "}}" inside the field name, rejecting "}" seems easier to explain and
avoid future unexpected problem if the templates change.
The ":" are used to separate filters, and rejecting it in field name would ensure that there is no ambiguity.
