Usage

Basic CLI Controller

from spakky.plugins.typer.stereotypes.cli_controller import CliController, command

@CliController("user")
class UserCliController:
    def __init__(self, user_service: UserService) -> None:
        self.user_service = user_service

    @command("list")
    async def list_users(self) -> None:
        """List all users."""
        users = await self.user_service.list_all()
        for user in users:
            print(f"{user.id}: {user.name}")

    @command("create")
    async def create_user(self, name: str, email: str) -> None:
        """Create a new user."""
        user = await self.user_service.create(name, email)
        print(f"Created user: {user.id}")

    @command("delete")
    async def delete_user(self, user_id: int) -> None:
        """Delete a user by ID."""
        await self.user_service.delete(user_id)
        print(f"Deleted user: {user_id}")

CLI Usage

# List all users
python main.py user list

# Create a new user

    ) -> None:
        """Execute pending database migrations."""
        if dry_run:
            print("Dry run mode - no changes will be made")
        # Migration logic here
