What's Changed

new diagnostic rules

reportIncompatibleUnannotatedOverride

pyright's reportIncompatibleVariableOverride rule does not report an error if the attribute in the base class does not have a type annotation:

class A:
    value = 1  # inferred as `int`


class B(A):
    value = None  # no error, even though the type on the base class is `int` and the type here is `None`

the new reportIncompatibleUnannotatedOverride rule will report an error in such cases. note that this rule is intended to replace reportUnannotatedClassAttribute in the future, but it is currently disabled by default. see the docs for more information

implemented in #1207

reportInvalidAbstractMethod

pyright ignores methods decorated with @abstractmethod if the class is not abstract:

from abc import abstractmethod


class Foo:
    @abstractmethod
    def foo(): ...

Foo()  # no error

the new reportInvalidAbstractMethod rule will report an error on the method definition. see the docs for more info

implemented in in #1238

other changes

• update the pylance modal dialog to just disable the conflicting settings instead of uninstall pylance because vscode always just reinstalls it automatically by @DetachHead in #1229
• add option to configure the path to the baseline file by @ivanbelenky in #1234
• update pycharm documentation and config by @DetachHead in #1219
• fix upstream bug where basedpyright.disableLanguageServices incorrectly disables diagnostics when pull diagnostics is enabled by @DetachHead in #1231
