Some times I try to figure out which Iceweasel browser plugin to
-install to get support for a given MIME type. Thanks to
-specifications
-done by Ubuntu and Mozilla, it is possible to do this in Debian.
-Unfortunately, not very many packages provide the needed meta
-information, Anyway, here is a small script to look up all browser
-plugin packages announcing ther MIME support using this specification:
-
-
-#!/usr/bin/python
-import sys
-import apt
-def pkgs_handling_mimetype(mimetype):
- cache = apt.Cache()
- cache.open(None)
- thepkgs = []
- for pkg in cache:
- version = pkg.candidate
- if version is None:
- version = pkg.installed
- if version is None:
- continue
- record = version.record
- if not record.has_key('Npp-MimeType'):
- continue
- mime_types = record['Npp-MimeType'].split(',')
- for t in mime_types:
- t = t.rstrip().strip()
- if t == mimetype:
- thepkgs.append(pkg.name)
- return thepkgs
-mimetype = "audio/ogg"
-if 1 < len(sys.argv):
- mimetype = sys.argv[1]
-print "Browser plugin packages supporting %s:" % mimetype
-for pkg in pkgs_handling_mimetype(mimetype):
- print " %s" %pkg
-
-
-
It can be used like this to look up a given MIME type:
-
-
-% ./apt-find-browserplug-for-mimetype
-Browser plugin packages supporting audio/ogg:
- gecko-mediaplayer
-% ./apt-find-browserplug-for-mimetype application/x-shockwave-flash
-Browser plugin packages supporting application/x-shockwave-flash:
- browser-plugin-gnash
-%
-
-
-
In Ubuntu this mechanism is combined with support in the browser
-itself to query for plugins and propose to install the needed
-packages. It would be great if Debian supported such feature too. Is
-anyone working on adding it?

Update 2013-01-18 14:20: The Debian BTS
-request for icweasel support for this feature is
-#484010 from 2008 (and
-#698426 from today). Lack
-of manpower and wish for a different design is the reason thus feature
-is not yet in iceweasel from Debian.
