The correct Python 3 idiom is raise E from V but since we can't detect instance-hood by syntax alone and since any client code would have to be changed as well, we don't automate this. � )�pytree)�token)� fixer_base)�Name�Call�Attr�ArgList�is_tuplec @ s( e Z d Z d Z d Z d d � Z d S)�FixRaiseTzB raise_stmt< 'raise' exc=any [',' val=any [',' tb=any]] > c C s� | j } | d j � } | j t j k rE d } | j | | � d St | � r� x* t | � r} | j d j d j � } qT Wd | _ d | k r� t j | j t d � | g � } | j | _ | S| d j � } t | � rd d � | j d d � D� } n d | _ | g } d | k r�| d j � } d | _ | } | j t j k sa| j d k rpt | | � } t | t d � � t | g � g } t j | j t d � g | � } | j | _ | St j | j t d � t | | � g d | j �Sd S)N�excz+Python 3 does not support string exceptions� � � �val�raisec S s g | ] } | j � � q S� )�clone)�.0�cr r �</opt/alt/python35/lib64/python3.5/lib2to3/fixes/fix_raise.py� <listcomp>D s z&FixRaise.transform.<locals>.<listcomp>� �tb�None�with_traceback�prefix���)�symsr �typer �STRINGZcannot_convertr Zchildrenr r ZNodeZ raise_stmtr �NAME�valuer r r Z simple_stmt) �selfZnodeZresultsr r �msg�newr �argsr �eZwith_tbr r r � transform& s@ ! # !%" zFixRaise.transformN)�__name__� __module__� __qualname__Z BM_compatibleZPATTERNr' r r r r r s r N)�__doc__r r Zpgen2r r Z fixer_utilr r r r r ZBaseFixr r r r r �<module> s (
