Pyright

Enhancement: Added code to interpret the python.path VS Code setting in the same manner as the Python VS Code extension. In particular, it now handles the special-case value of "python" to mean "use the default python interpreter" rather than treating it as a relative path.

Enhancement: Added special-case handling of `__import__` built-in call so it always returns `Any` type.

Bug Fix: Fixed bug in code that determines whether code is reachable.

Bug Fix: Fixed static expression evaluation for expressions that involve python platform when no platform is specified.

Bug Fix: Fixed bug in alias resolution logic that caused the definition provider not to take the user to the right location in cases where there were multiple alias hops.

Bug Fix: Changed implicit module symbol `__path__` to be properly typed as `Iterable[str]` rather than str.

Bug Fix: Fixed regression introduced in 1.0.77 that caused imports of third-party libraries to generate "not a known member of module" error messages.

This version includes a big change in the way pyright tracks variable declarations. This change should not be visible to users. It was done in preparation for an upcoming change in the analysis engine.

New Feature: Signature help provider now extracts parameter-specific comments and presents them in the help text when typing function arguments.

Enhancement: Added knowledge of `__doc__` symbol to all modules.

Bug Fix: Fixed crash that resulted when launching the production VS Code extension in debug mode.

Bug Fix: Fixed recent regression that broke type completions within import statements.

Bug Fix: Fixed issue that caused analysis to fail after repeated edits while in "watch" mode.

This version includes a big change in the way pyright processes import statements. This change should not be visible to users. It was done in preparation for an upcoming change in the type analysis engine.

Bug Fix: Fixed Windows-specific path processing bug.

Bug Fix: Fixed bug that caused "import cycle" errors to persist even after they were corrected.

Enhancement: Added support for bidirectional type inference for assignments where the LHS is an indexed expression.

Bug Fix: Switched to a new file system watching mechanism so "--watch" works correctly on Linux.

Bug Fix: Fixed recent regression that caused errors to be reported incorrectly after editing a dependent source file.

New Feature: Added support for Python 3.8 assignment expressions (aka walrus operator).

Enhancement: Bumped latest stable build of python from 3.7 to 3.8, so the latter is now the default setting for pyright.

Enhancement: Added verbose logging for file system watchers.

Enhancement: Improved robustness of code that invokes the local python interpreter to query for paths. Thanks to Rami Chowdhury for the contribution.
