get_literal_defaults

def get_literal_defaults(
        node: Union[ast.FunctionDef, ast.AsyncFunctionDef]) -> Dict[str, str]

View source on GitHub

Extract defaults from function definition node literally, as pieces of source code

get_func_def_node

def get_func_def_node(
        f: AnyFun) -> Union[ast.FunctionDef, ast.AsyncFunctionDef]

View source on GitHub

Finds the function definition node for function f by parsing the source code of the f's module

find_outer_func_def

def find_outer_func_def(node: ast.AST) -> Optional[ast.FunctionDef]

View source on GitHub

Finds the outer function definition node in which the 'node' is contained. Returns None if 'node' is toplevel.

set_ast_parents

def set_ast_parents(tree: ast.AST) -> None

View source on GitHub

Walks AST tree and sets the parent attr in each node to the node's parent. Toplevel nodes (parent is a tree) have the parent attr set to None.

creates_func_def_name_node

def creates_func_def_name_node(func_def: ast.FunctionDef,
                               source_lines: Sequence[str]) -> ast.Name

View source on GitHub

Recreate function name as a ast.Name with known source code location

rewrite_python_script

def rewrite_python_script(
        source_script_lines: List[str],
        transformed_nodes: List[Tuple[ast.AST, ast.AST]]) -> List[str]

View source on GitHub

Replaces all the nodes present in transformed_nodes in the script_lines. The transformed_nodes is a tuple where the first element is must be a node with full location information created out of script_lines
