This module defines two useful functions: guess_type(url, strict=True) -- guess the MIME type and encoding of a URL. guess_extension(type, strict=True) -- guess the extension for a given MIME type. It also contains the following, for tuning the behavior: Data: knownfiles -- list of files to parse inited -- flag set when init() has been called suffix_map -- dictionary mapping suffixes to suffixes encodings_map -- dictionary mapping suffixes to encodings types_map -- dictionary mapping suffixes to types Functions: init([files]) -- parse a list of files, default knownfiles (on Windows, the default values are taken from the registry) read_mime_types(file) -- parse one file, return a dictionary or None � N� knownfiles�inited� MimeTypes� guess_type�guess_all_extensions�guess_extension�add_type�init�read_mime_types� suffix_map� encodings_map� types_map� common_typesz/etc/mime.typesz/etc/httpd/mime.typesz/etc/httpd/conf/mime.typesz/etc/apache/mime.typesz/etc/apache2/mime.typesz$/usr/local/etc/httpd/conf/mime.typesz"/usr/local/lib/netscape/mime.typesz/usr/local/etc/mime.typesFc @ s` e Zd ZdZddd�Zddd�Zddd �Zdd d �Zdd d �Zddd�Z ddd�Z d dd�Z dS ) r z�MIME-types datastore.

Return value is a tuple (type, encoding) where type is None if the type can't be guessed (no or unknown suffix) or a string of the form type/subtype, usable for a MIME Content-type header; and encoding is None for no encoding or the name of the program used to encode (e.g. compress or gzip). The mappings are table driven. Encoding suffixes are case sensitive; type suffixes are first tried case sensitive, then case insensitive. The suffixes .tgz, .taz and .tz (case sensitive!) are all mapped to '.tar.gz'. (This is table-driven too, using the dictionary suffix_map.) Optional `strict' argument when False adds a bunch of commonly found, but non-standard types. �data�,r )NN�;N�=�/� text/plainTF) �os�fspath�urllib�parseZ _splittype�find� posixpath�splitextr r r �lower) r �urlr ZschemeZcommaZsemir �baser �encodingr r r r r a sB zMimeTypes.guess_typec C sL |� � }| jd �|g �}|sH| jd �|g �D ]}||kr0|�|� q0|S )a� Guess the extensions for a file based on its MIME type.
