The dictionary maps a MIME type (in all lowercase, e.g. 'text/plain') to a list of dictionaries corresponding to mailcap entries. The list collects all the entries for that MIME type from all available mailcap files. Each dictionary contains key-value pairs for that MIME type, where the viewing command is stored with the key "view". r �r)�listmailcapfiles�open�OSError�_readmailcapfile�items)�capsr Zmailcap�fpZmorecaps�key�valuer r r r s c C sP dt jkr"t jd } | �t j�}n*dt jkr8t jd }nd}|d dddg}|S )z7Return a list of all mailcap files found on the system.ZMAILCAPS�HOME�.z /.mailcapz /etc/mailcapz/usr/etc/mailcapz/usr/local/etc/mailcap)�os�environ�split�pathsep)ZpathstrZmailcaps�homer r r r - s �r c C s t �dtd� t| d�\}}|S )z?Read a mailcap file and return a dictionary keyed by MIME type.z2readmailcapfile is deprecated, use getcaps instead� N)�warnings�warn�DeprecationWarningr )r r �_r r r �readmailcapfile? s �r c C s� i }| � � }|sq�|d dks|�� dkr,q|}|dd� dkrb| � � }|sPd}|dd� | }q0t|�\}}|r|sxq|dk r�||d< |d 7 }|�d �}tt|��D ]}|| �� ||< q�d �|��� }||kr�|| �|� q|g||< q||fS ) a� Read a mailcap file and return a dictionary keyed by MIME type.
