DESCRIPTIONMIME types are used in MIME entities, for instance as part of e-mail and HTTP traffic. Sometimes real knowledge about a mime-type is need. Objects of "MIME::Type" store the information on one such type.
- overload: string comparison
- When a MIME::Type object is compared to either a string or another MIME::TYpe, the equals() method is called. Comparison is smart, which means that it extends common string comparison with some features which are defined in the related RFCs.
- overload: stringification
The stringification (use of the object in a place where a string
is required) will result in the type name, the same as type()
example: use of stringification
my $mime = MIME::Type->new('text/html'); print "$mime\n"; # explicit stringification print $mime; # implicit stringification
Create (instantiate) a new MIME::Type object which manages one
-Option --Default encoding <depends on type> extensions  simplified <derived from type> system undef type <required>
- encoding => '7bit'|'8bit'|'base64'|'quoted-printable'
- How must this data be encoded to be transported safely. The default depends on the type: mimes with as main type "text/" will default to "quoted-printable" and all other to "base64".
- extensions => REF-ARRAY
- An array of extensions which are using this mime.
- simplified => STRING
- The mime types main- and sub-label can both start with "x-", to indicate that is a non-registered name. Of course, after registration this flag can disappear which adds to the confusion. The simplified string has the "x-" thingies removed and are translated to lower-case.
- system => REGEX
- Regular expression which defines for which systems this rule is valid. The REGEX is matched on $^O.
- type => STRING
- The type which is defined here. It consists of a type and a sub-type, both case-insensitive. This module will return lower-case, but accept upper-case.
- Returns the type of encoding which is required to transport data of this type safely.
- Returns a list of extensions which are known to be used for this mime type.
- $obj->simplified( [$string] )
- MIME::Type->simplified( [$string] )
Returns the simplified mime type for this object or the specified STRING.
Mime type names can get officially registered. Until then, they have to
carry an "x-" preamble to indicate that. Of course, after recognition,
the "x-" can disappear. In many cases, we prefer the simplified version
of the type.
example: results of simplified()
my $mime = MIME::Type->new(type => 'x-appl/x-zip'); print $mime->simplified; # 'appl/zip' print $mime->simplified('text/PLAIN'); # 'text/plain' print MIME::Type->simplified('x-xyz/x-abc'); # 'xyz/abc'
- Returns the regular expression which can be used to determine whether this type is active on the system where you are working on.
- Returns the long type of this object, for instance 'text/plain'
- Compare this mime-type object with a STRING or other object. In case of a STRING, simplification will take place.
- Old name for isText().
- Returns true when the type is not known to be text. See isText().
- [2.00] Return "true" when the type is defined for experimental use; the subtype starts with "x."
- [2.00] Return "true" when the type is defined by a person for private use; the subtype starts with "prs."
- Mime-types which are not registered by IANA nor defined in RFCs shall start with an "x-". This counts for as well the media-type as the sub-type. In case either one of the types starts with "x-" this method will return false.
- Returns true when the type is in the list of known signatures.
- [2.05] All types which may have the charset attribute, are text. However, there is currently no record of attributes in this module... so we guess.
- [2.00] Return "true" when the type is defined by a vendor; the subtype starts with "vnd."
The media type of the simplified mime.
For 'text/plain' it will return 'text'.
For historical reasons, the 'mainType' method still can be used to retrieve the same value. However, that method is deprecated.
- The sub type of the simplified mime. For 'text/plain' it will return 'plain'.
- Error: Type parameter is obligatory.
- When a MIME::Type object is created, the type itself must be specified with the "type" option flag.
