Writing Recipes

from dataclasses import dataclass, field
from rewrite import Recipe, option
from rewrite.python import PythonVisitor

@dataclass
class ChangeImport(Recipe):
    """Changes an import from one module to another."""

    old_module: str = field(metadata=option(
        display_name="Old module",
        description="The module to change imports from",
        example="flask"
    ))

    new_module: str = field(metadata=option(
