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. cs |_|S)N)_params)Z rule_func)paramsrr decoratePszparameterized..decorater)r&r'r)r&r parameterizedFs r(cCspd}xft|D]Z}|jdrt||}t|drt|||jdk rPt||q|stjdt ddd}qW|S) z Class decorator to generate rules from parameterized rule templates.
