Parameterized rule methods must be named starting with 'p_' and contain 'xxx', and their docstrings may contain 'xxx' and 'yyy'. These will be replaced by the given parameter tuples. For example, ``p_xxx_rule()`` with docstring 'xxx_rule : yyy' when decorated with ``@parameterized(('id', 'ID'))`` produces ``p_id_rule()`` with the docstring 'id_rule : ID'. Using multiple tuples produces multiple rules. c s � | _ | S r )�_params)Z rule_func��paramsr r �decorateP s z parameterized.<locals>.decorater )r) r* r r( r � parameterizedF s r+ c C sl d}t | �D ]Z}|�d�r t| |�}t|d�r t| |� |jdurNt| |� q |s tjdt dd� d}q | S ) z� Class decorator to generate rules from parameterized rule templates.
