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 Zd ZdZdZdd� ZdS )�FixRaiseTzB raise_stmt< 'raise' exc=any [',' val=any [',' tb=any]] > c C sl | j }|d �� }|jtjkr2d}| �||� d S t|�rbx t|�rZ|jd jd �� }q<W d|_d|kr�t � |j t d�|g�}|j|_|S |d �� }t|�r�dd � |jdd � D �}n d |_|g}d |k�rF|d �� } d | _|} |jtj ks�|jd k�rt||�} t| t d��t| g�g } t � |jt d�g| �}|j|_|S t j |j t d�t||�g|jd�S d S )N�excz+Python 3 does not support string exceptions� � � �val�raisec S s g | ] }|� � �qS � )�clone)�.0�cr r �</opt/alt/python37/lib64/python3.7/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
