Curses screens, windows and pads are typed as curses.window, and the
widgets that may get no parent window take curses.window | None.
- EventHandler is generic over a ParamSpec, so each handler declares
the arguments it passes, and MenuView is generic over the item its
on_confirm hands out. Choice callbacks take no arguments.
- Scrollable is generic over its items, which DataTable and ListBox
fix to tuple[str, str] and str.
- random.choice() and choice_low() are generic over the sequence, so
the casts at their call sites are gone. BasicUserInterface.menu()
and util.first() are generic too.
- Signal callbacks and their payloads are Callable[..., object] and
object, since emit() only forwards them.
- JSON values in game_data are object and narrowed by isinstance,
and data files are Traversable.
- Signal handlers take an int and a FrameType | None, and
list_players() takes a TextIO.
- The focus_standout() context managers return
Generator[None, None, None].
Any remains in three places: Player.__setstate__, whose pickled
__dict__ holds values of every type; Focusable.__init__, a mixin that
passes *args and **kwargs through to the next class; and the values
load_game_data() collects, whose element type depends on the field
each one fills.
ty reported 20 diagnostics, and 0.0.89 adds a few more; this clears
them all without suppressions.
- The quest monster is held in a local before being stored on the
quest book, so its name no longer reads from an Optional.
- PgUp/PgDn narrow the focused window with isinstance against a
runtime-checkable PageScrollable protocol instead of hasattr.
- The ^t cheat used to monkeypatch SignalMixin.emit. SignalMixin now
has a muted() context manager that emit() checks, and it restores
emission even if a tick raises.
- GameView keeps its children as GameWindow, a protocol declaring
stop() and sync(), so the cheat's resync type-checks.
- curses.ascii is imported explicitly where it is used.
- ProgressBarWindow is now Focusable itself, instead of calling
Focusable.focus_standout() on a class that is not Focusable. Its
four subclasses drop the duplicate Focusable base; the MRO and
initialisation order are unchanged.
- MainMenu narrows the Optional pad before colouring the logo.
- The tests that record tasks assert player.task is set.
- Context managers are annotated as Generator rather than Iterator,
which ty flags as deprecated for @contextmanager.
- The redundant cast() around getch() is gone.
- The frozen GameData test assigns through setattr(), since the
direct assignment is an error by design.
Bug fixes:
- ListBox.select(None) crashed on `None < 0`; it now clears the
selection, as DataTable.select(None) already does.
- ListBox.get() caught ValueError, which indexing never raises; it
now catches IndexError, so an out-of-range index returns None as
intended.
Python 3.10 is the minimum, so annotations use `X | None`, `list[X]`
and friends, enforced by ruff's pyupgrade rules. The remaining typing
names are imported directly, with abstract types coming from
collections.abc. first() is now generic over the item and default.
