_ClassType MimeTypes

MIME-types datastore.

This datastore can handle information from mime.types-style files and supports basic determination of MIME type from a filename or URL, and can guess a reasonable extension given a MIME type.

Instance Methods [hide private]
 
__init__(self, filenames=(), strict=True)
 
add_type(self, type, ext, strict=True)
Add a mapping between a type and an extension.
 
guess_type(self, url, strict=True)
Guess the type of a file based on its URL.
 
guess_all_extensions(self, type, strict=True)
Guess the extensions for a file based on its MIME type.
 
guess_extension(self, type, strict=True)
Guess the extension for a file based on its MIME type.
 
read(self, filename, strict=True)
Read a single mime.types-format file, specified by pathname.
 
readfp(self, fp, strict=True)
Read a single mime.types-format file.

add_type(self, type, ext, strict=True)

 

Add a mapping between a type and an extension.

When the extension is already known, the new type will replace the old one. When the type is already known the extension will be added to the list of known extensions.

If strict is true, information will be added to list of standard types, else to the list of non-standard types.

guess_type(self, url, strict=True)

 

Guess the type of a file based on its URL.

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.

guess_all_extensions(self, type, strict=True)

 

Guess the extensions for a file based on its MIME type.

Return value is a list of strings giving the possible filename extensions, including the leading dot ('.'). The extension is not guaranteed to have been associated with any particular data stream, but would be mapped to the MIME type `type' by guess_type().

Optional `strict' argument when false adds a bunch of commonly found, but non-standard types.

guess_extension(self, type, strict=True)

 

Guess the extension for a file based on its MIME type.

Return value is a string giving a filename extension, including the leading dot ('.'). The extension is not guaranteed to have been associated with any particular data stream, but would be mapped to the MIME type `type' by guess_type(). If no extension can be guessed for `type', None is returned.

Optional `strict' argument when false adds a bunch of commonly found, but non-standard types.

read(self, filename, strict=True)

 

Read a single mime.types-format file, specified by pathname.

If strict is true, information will be added to list of standard types, else to the list of non-standard types.

readfp(self, fp, strict=True)

 

Read a single mime.types-format file.

If strict is true, information will be added to list of standard types, else to the list of non-standard types.
