MIME::Types - Definition of MIME types
is a Exporter
my $mimetypes = MIME::Types->new;
my MIME::Type $plaintext = $mimetypes->type('text/plain');
my MIME::Type $imagegif = $mimetypes->mimeTypeOf('gif');
MIME types are used in MIME compliant lines, for instance as part of
e-mail and HTTP traffic, to indicate the type of content which is
transmitted. Sometimes real knowledge about a mime-type is need.
This module maintains a set of MIME::Type objects, which each describe
one known mime type. There are many types defined by RFCs and vendors,
so the list is long but not complete. Please don't hestitate to ask to
add additional information.
If you wish to get access to the "mime.types" files, which are
available on various places in UNIX and Linux systems, then have a look
Create a new "MIME::Types" object which manages the data. In the
current implementation, it does not matter whether you create this
object often within your program, but in the future this may
. only_complete => BOOLEAN
Only include complete MIME type definitions: requires at least
one known extension. This will reduce the number of entries
--and with that the amount of memory consumed-- considerably.
In your program you have to decide: the first time that you
call the creator ("new") determines whether you get the full or
the partial information.
Add one or more TYPEs to the set of known types. Each TYPE is a
"MIME::Type" which must be experimental: either the main-type or
the sub-type must start with "x-".
Please inform the maintainer of this module when registered types
are missing. Before version MIME::Types version 1.14, a warning
was produced when an unknown IANA type was added. This has been
removed, because some people need that to get their application to
work locally... broken applications...
Returns a list of all defined extensions.
Returns the "MIME::Type" object which belongs to the FILENAME (or
simply its filename extension) or "undef" if the file type is
unknown. The extension is used, and considered case-insensitive.
In some cases, more than one type is known for a certain filename
extension. In that case, one of the alternatives is chosen at
example: use of mimeTypeOf()
my MIME::Types $types = MIME::Types->new;
my MIME::Type $mime = $types->mimeTypeOf('gif');
my MIME::Type $mime = $types->mimeTypeOf('jpg');
Return the "MIME::Type" which describes the type related to STRING.
One type may be described more than once. Different extensions is
use for this type, and different operating systems may cause more
than one "MIME::Type" object to be defined. In scalar context,
only the first is returned.
Returns a list of all defined mime-types
The next functions are provided for backward compatibility with
MIME::Types versions 0.06 and below. This code originates from Jeff
Okamoto email@example.com and others.
This function takes a media type and returns a list or anonymous
array of anonymous three-element arrays whose values are the file
name suffix used to identify it, the media type, and a content
TYPE can be a full type name (contains '/', and will be matched in
full), a partial type (which is used as regular expression) or a
real regular expression.
Like "mimeTypeOf", but does not return an "MIME::Type" object. If
the file +type is unknown, both the returned media type and
encoding are empty strings.
example: use of function by_suffix()
use MIME::Types 'by_suffix';
my ($mediatype, $encoding) = by_suffix 'image.gif';
my $refdata = by_suffix 'image.gif';
my ($mediatype, $encoding) = @$refdata;
This method has been removed: mime-types are only useful if
understood by many parties. Therefore, the IANA assigns names
which can be used. In the table kept by this "MIME::Types" module
all these names, plus the most often used termporary names are
kept. When names seem to be missing, please contact the maintainer
