v1.35.0 (pyright 1.1.407)

What's Changed

improved completions for Literals and enums

in pyright/pylance, you only get completions for Literals that contain strings:

but in basedpyright, this now also works with Literals that contain other types, such as int, bool and Enum values:

unlike pyright/pylance, basedpyright now also supports completions for enum values:

this also works for other types of enums such as IntEnum and StrEnum

What's Changed

enableBasedFeatures

until now, basedpyright-exclusive type checking features have mostly come in the form of an additional diagnostic rule that users have the option to disable. but this approach limits us from making any interesting breaking changes to the type system itself.

this release introduces a new setting called enableBasedFeatures, which is disabled by default. enabling it will opt you into any changes we make that introduce breaking changes to the type system. in other words, if you're developing a library and expect your users to be using other type checkers, you should probably keep it disabled.

currently only one feature is behind this flag: the new skip_replace argument to the @dataclass_transform decorator, implemented by @decorator-factory in #1568

new diagnostic rule - reportSelfClsDefault

Pyright allows specifying a default value for self in instance methods and cls in class methods:

class Foo:
    def foo(self=1):
        ...

this is almost certainly a mistake, so this new diagnostic rule will warn against it.

also implemented by @decorator-factory in #1581
