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`.

Return `true` if the `Expr` contains an expression that appears to include a side-effect (like a function call). Accepts a closure that determines wh

Helper function to create a directory and all parent directories

Return the positional argument at the given index, or `None` if no such argument exists.

Return true if `self & other` should simplify to `Never`: if the intersection of the two types could never be inhabited by any possible runtime value.

Returns whether this is a known class.

Returns an iterator over the fixes in the map, along with the file path.

Pushes a new [`Binding`] and returns its [`BindingId`].

Generic function to remove arguments or keyword arguments in function calls and class definitions. (For classes, `args` should be considered `bases`.)

Set the fix for this diagnostic.

Calls `self`. Returns a [`CallError`] if `self` is (always or possibly) not callable, or if the arguments are not compatible with the formal parameter

Look up a dunder method on the meta-type of `self` and call it. Returns an `Err` if the dunder method can't be called, or the given arguments are not

Returns an iterator over all [`NodeId`] ancestors, starting from the given [`NodeId`].

Consumes the next character

Returns an [`Iterator`] over the current statement hierarchy, from the current [`Stmt`] through to any parents.

Returns the node following the comment. The direct child node (ignoring lists) of the [`enclosing_node`](DecoratedComment::enclosing_node) that follo

Extract the leading indentation from a line.

Returns `true` if the text only consists of ASCII characters

Returns `true` if a string is a valid Python identifier (e.g., variable name).

Returns `true` if this is a keyword-variadic parameter.

Returns `true` if a function definition is an `@overload`.

Loads a reference to the parsed module. Note that holding on to the reference will prevent garbage collection of the AST. This method will reparse th

Returns `true` if the given name matches any of the ignored patterns.

Executes `uv workspace metadata` and parses and validates its output.

Parses the content and returns its AST

Add a primary annotation with a message. If the message is empty, then an annotation without any message be created. See the docs on `TestEnvironmen

Returns the [`QualifiedName`] of the imported name (e.g., given `from foo import bar as baz`, returns `["foo", "bar"]`).

Returns the [`TextRange`] for the diagnostic.

Compute the overall effective return type of this `ConstructorBinding`.

Generate source code from a [`Stmt`].

Returns all the tokens for the parsed output.

Returns the client settings for the workspace that this document belongs to.

Returns the [`BindingId`] if this symbol resolves to a concrete binding.

Returns an iterator over the bytes of the concatenated bytestring.

Returns an iterator over the direct child scopes of `scope`.

Closes the virtual file.

Return the underlying source code.
