Infer the public type of a class member/symbol (its type as seen from outside its scope) in the given `scope`.

Return the [`LintContext`] for the current analysis. Note that you should always prefer calling methods like `settings`, `report_diagnostic`, or `is_

Creates a directory at `path`. All enclosing directories are created if they don't exist.

Returns the `UnifiedFile` attached to this `Span`.

If the type is a union (or a type alias that resolves to a union), filters union elements based on the provided predicate. Otherwise, returns the typ

Returns `true` if the string list of `codes` includes `code` (or an alias thereof).

Consumes the [`Parsed`] output and returns the module body as a [`Suite`].

Return `true` if an [`Expr`] is a literal `True`.

Returns `true` if this is either a positional-only or standard (positional or keyword) parameter.

Return `true` if this class is a protocol class. In an ideal world, perhaps we wouldn't hardcode this knowledge here; instead, we'd just look at the

Joins the objects by placing the specified separator between every two items. ## Examples Joining different tokens by separating them with a comma a

Lookup the type of `symbol` in a given known module. Returns `Place::Undefined` if the given known module cannot be resolved for some reason.

Returns an iterator over the [leading](self#leading-comments), [dangling](self#dangling-comments), and [trailing](self#trailing) comments of `node`.

Marks the comment as formatted

Applies both constraint kinds between the place's last materialized nodes and `target`. The place's node must be an ancestor of `target`. After mater

Extract parameter documentation from popular docstring formats. Returns a map of parameter names to their documentation.

Given a [`NodeId`], return the [`NodeId`] of the parent statement, if any.

Formats `content` enclosed by the `left` and `right` parentheses. The implementation also ensures that expanding the parenthesized expression (or any

Return the [`PythonVersion`] to use for parsing. This will be either the Python version specified by the user or the latest supported version if unse

Get qualifiers for an annotation expression.

Restore the semantic model to the given [`Snapshot`].

Sends a request to display an error to the client with a formatted message. The error is sent in a `window/showMessage` notification. Logs an error i

Create a new signature with the given definition.

Add a symbol to the place table and the use-def map. Return the [`ScopedPlaceId`] that uniquely identifies the symbol in both.

Applies higher-precedence options to this project. Options applied later take precedence over options applied earlier.

Returns the string representation of the quote style.

Attach a Jupyter notebook cell index.

Return the remaining input as a string slice.

The total length of the string's closer. This is always equal to `self.quote_len()`, except when the string is unclosed, in which case the length is z
