9c8a0f1a4a Improved error message for set invariance type violations. This comes from mypy issue https://github.com/python/mypy/issues/16631. 2023-12-07 10:52:16 -08:00

Added a new typeCheckingMode called "standard". It's a subset of "strict" but a superset of "basic". It is the new default mode, and it should cover all of the required checks for conformance with the Python typing standard. This addresses #66607. (#6627) 2023-12-01 23:44:12 -08:00

Added support for parameter type inference for lambdas whose parameters include default arguments. This is analogous to the logic used for unannotated function parameters with default arguments. This addresses #6558. (#6563) 2023-11-27 17:51:31 -08:00

Added support for python.analysis.include, `python.analysis.exclude… (#6251) 
* Added support for `python.analysis.include`, `python.analysis.exclude` and `python.analysis.ignore` settings. These have been implemented in pylance for a while now, but they were never implemented previously in pyright. Also fixed a bug in the original implementation that caused the config file not to override the language server settings for `python.analysis.exclude` and `python.analysis.ignore` as it should. This addresses #6250.

* Removed references to pylance in the help text.

Added a new configuration switch disableBytesTypePromotions that controls whether bytearray and memoryview should be implicit subtypes of bytes. This switch defaults to false in basic type checking mode and true in strict mode. Eventually, we will probably have it default to true in all modes. (#6024)

Added a new configuration option deprecateTypingAliases that enables deprecation detection and reporting for symbols imported from the typing module that are deprecated according to PEP 585 and 604. The option is currently disabled by default (even in strict mode) but can be enabled manually. This addresses #3598. (#5812)

050a3c6cea Fixed a bug in the command-line version of pyright where it did not enable "auto search paths", so it didn't automatically add "src" as an extra path. This addresses https://github.com/microsoft/pyright/issues/4771. 2023-07-31 23:27:45 -06:00

Modified type inference logic so methods that raise an exception whose type derives from NotImplementedError is not inferred to return NoReturn. Previously, only NotImplementedError was exempted, not subclasses. This addresses https://github.com/microsoft/pyright/issues/5608. (#5609)

d81ffb7b5c Added a new configuration options flag called enableExperimentalFeatures that controls whether certain experimental features are enabled. Currently there are three features under this flag: StrictTypeGuard, ReadOnly fields for typed dicts, and inlined TypedDict definitions.

Fixed an inconsistency in reporting of unbound variables when the variable is captured by an inner scope. The new behavior correctly identifies unbound (or potentially unbound) variables in cases where the captured variable is narrowed. This happens when there are no assignments to the variable after it is captured. This addresses #5548. (#5551) 
Fixed a bug in type narrowing for captured variables. Captured variables that are modified in other scopes using a `nonlocal` or `global` binding should be ineligible for type narrowing.

6a25a7bf0b Removed the requirement that a TypedDict be marked @final for it to be considered for type narrowing as part of a S in D type guard pattern. This requirement wasn't sound because TypedDict is a structural type (i.e. a protocol), so @final doesn't have any real meaning. 2023-07-17 08:01:52 -07:00

Clarification of --version argument usage string (#5308) 
* Update command-line.md

clarify that `--version` prints the version *and exits*

* Update --version usage string

Clarifies that `--version` prints the version *and exits*, this is fairly common language used by most CLI apps to indicate what the behavior of `--version` is. It may surprise new users that `--version` exits rather than appending the version with the previous language.

Update ci-integration.md (#5259) 
When both scripts are executed in `scripts:` section, and `pyright` reports error, second script is not executed.

Best way to ensure report are always converted, is to use `after_script:` block.

746e03a49d Modified overload matching algorithm to better match that of mypy. In particular, if overload matching is ambiguous due to an Any or Unknown anywhere within an argument type (even within type arguments) and the resulting filtered overloads return the same generic type but with different type arguments, the resulting type was previously the return type of the first filtered overload. It is now the common generic type with erased type arguments. This addresses https://github.com/microsoft/pyright/issues/5216. 2023-06-03 17:36:09 -06:00

9f81564a46 Changed reportImportCycles so it is not on by default in "strict" type checking mode. It is highly opinionated and should be used only in cases where the developer opts into it. 2023-04-08 10:29:14 -07:00
