The mime-types library provides a library and registry for information about
MIME content type definitions. It can be used to determine defined filename
extensions for MIME types, or to use filename extensions to look up the likely
MIME type definitions.
MIME content types are used in MIME-compliant communications, as in e-mail or
HTTP traffic, to indicate the type of content which is transmitted. The
mime-types library provides the ability for detailed information about MIME
entities (provided as an enumerable collection of MIME::Type objects) to be
determined and used programmatically. There are many types defined by RFCs and
vendors, so the list is long but by definition incomplete; don't hesitate to to
add additional type definitions (see Contributing.rdoc). The primary sources
for MIME type definitions found in mime-types is the IANA collection of
registrations (see below for the link), RFCs, and W3C recommendations.
This is release 2.2, mostly changing how the MIME type registry is updated from
the IANA registry (the format of which was incompatibly changed shortly before
this release) and taking advantage of the extra data available from IANA
registry in the form of MIME::Type#xrefs. In addition, the {LTSW
list}[http://www.ltsw.se/knbase/internet/mime.htp] has been dropped as a
supported list.
As a reminder, mime-types 2.x is no longer compatible with Ruby 1.8 and
mime-types 1.x is only being maintained for security issues. No new MIME types
or features will be added.
mime-types (previously called MIME::Types for Ruby) was originally based on
MIME::Types for Perl by Mark Overmeer, copyright 2001 - 2009. It is built to
conform to the MIME types of RFCs 2045 and 2231. It tracks the {IANA Media
Types registry}[https://www.iana.org/assignments/media-types/media-types.xhtml]
with some types added by the users of mime-types.
Changes:
## 2.3 / 2014-05-23
* Bugs:
* Fixed a bug in <tt>MIME::Types#type_for</tt> where type specifications that
did not match a MIME::Type would be returned as +nil+ inside the returned
array. This was incorrect behaviour as those values should not have been
returned, resulting in an empty array.
* MIME Type Development Tools:
* As always, there are bugs in the IANA registry because it's manually
maintained. Some robustness has been added to properly writing file
template references where the file template reference is not a full media
type specification (e.g., 'amr-wb\+' instead of 'audio/amr-wb\+').
* Both the IANA and Apache import tools were unnecessarily case-sensitive in
matching against already-existing MIME types, resulting in extra work to
weed out duplicates that differed only in the case of the canonical content
type. This has been fixed.
