Returns an iterator over the patterns and keywords in source order.

If this type is a class instance, returns its class.

When set, builtins from completions are skipped. This is useful in tests to reduce noise for scope based completions. Not enabled by default.

Add an [`UnsupportedSyntaxError`] with the given [`UnsupportedSyntaxErrorKind`] and [`TextRange`] if its minimum version is less than [`Parser::target

Returns the python code as a `str`.

Infer the type of a binding.

Walk the `NewTypeBase` chain to find the underlying non-newtype `Type`. There might not be one if this `NewType` is cyclical, and we fall back to `obj

Return `true` if the given version is required.

Sets the working directory for the command.

Returns whether this constraint set never holds.

Returns `true` for [whitespace](https://docs.python.org/3/reference/lexical_analysis.html#whitespace-between-tokens) characters.

Return `true` if the call path is a reference to `typing.${target}`.

Returns whether this `TypedDict` is implicitly open, closed, or has explicit extra items. A class-based `TypedDict` inherits the first explicit polic

Parse the given Python source code using the specified [`ParseOptions`]. This is same as the [`parse`] function except that it doesn't check for any

Returns the "primary" span of this diagnostic if one exists. When there are multiple primary spans, then the first one that was added to this diagnos

Resolves a module name to a module.

Adds a "sub" diagnostic to this diagnostic. This is useful when a sub diagnostic has its own annotations attached to it. For the simpler case of a su

Adds a tag on the primary annotation for this diagnostic. This tag is associated with the primary annotation created for every `Diagnostic` that uses

Return an iterator over the bases of the class.

Returns whether this is a nominal instance of a particular [`KnownClass`].

Length of this annotation as displayed in the stderr output

Returns the pending materialization of a class-based protocol, if any.

Similar to [`Type::member`], but allows the caller to specify what policy should be used when looking up attributes. See [`MemberLookupPolicy`] for mo

Add leading or trailing whitespace to a snippet, if it's immediately preceded or followed by an identifier or keyword.

Specify files to be created in the `site-packages` mock directory

Returns the position encoding that was negotiated during initialization.

Infers the type of an `expression` that is guaranteed to be in the same file as the calling query. This is a small helper around [`infer_expression_t

Returns `true` if there are no fixes in the map.

Returns an iterator over all the overloads that matched for this call binding.

Returns the comment's preceding node. The direct child node (ignoring lists) of the [`enclosing_node`](DecoratedComment::enclosing_node) that precede

Pushes the given line as part of this code example.

A convenient wrapper around [`check_path`], that additionally asserts that fixes converge after a fixed number of iterations.

Writes the files to the file system. The operation overrides existing files with the same normalized path. Enclosing directories are automatically c

Return the body of the function-like node. If the node is a function definition that consists of more than a single return statement, returns `None`.
