If the original message has no From_ delimiter, a `standard' one is crafted. By default, this is False to inhibit the printing of any From_ delimiter. Note that for subobjects, no From_ line is printed. linesep specifies the characters used to indicate a new line in the output. The default value is determined by the policy.

Functionally identical to the base Generator except that the output is bytes and not string. When surrogates were used in the input to encode bytes, these are decoded back to bytes for output. If the policy has cte_type set to 7bit, then the message is transformed such that the non-ASCII bytes are properly content transfer encoded, using the charset unknown-8bit. The outfp object must accept bytes in its write method. � c C s | j �t|��dd�� d S )N�ascii�surrogateescape)r r r �encode)r r r r r r � s zBytesGenerator.writec C s t � S )N)r )r r r r r- � s zBytesGenerator._new_bufferc C s |� d�S )Nrv )rx )r r r r r r# � s zBytesGenerator._encodec C s< x*|� � D ] \}}| j�| j�||�� q W | �| j� d S )N)rC r r r Z fold_binaryr" )r r( rD rE r r r r5 � s z BytesGenerator._write_headersc s\ |j d krd S t|j �rH| jjdksH| jr:t�d|j �|_ | �|j � ntt | �� |� d S )NZ7bitz>From ) rK r r Zcte_typer rL rB r4 r r rN )r r( )r+ r r rN � s zBytesGenerator._handle_textc C s t �|�d�|�S )Nrv )rg rn rx )rk r ro r r r rf � s zBytesGenerator._compile_re)rp rq rr rs r\ r r- r# r5 rN r@ rt rf � __classcell__r r )r+ r r ~ s zD[Non-text (%(type)s) part of message omitted, filename %(filename)s]c @ s" e Zd ZdZd dd�Zdd� ZdS ) r z�Generates a text representation of a message.
