+ <div class="title">How to find a browser plugin supporting a given MIME type</div>
+ <div class="date">18th January 2013</div>
+ <div class="body"><p>Some times I try to figure out which Iceweasel browser plugin to
+install to get support for a given MIME type. Thanks to
+<a href="https://wiki.ubuntu.com/MozillaTeam/Plugins">specifications
+done by Ubuntu</a> 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:</p>
+
+<pre>
+#!/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
+</pre>
+
+<p>It can be used like this to look up a given MIME type:</p>
+
+<pre>
+% ./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
+%
+</pre>
+
+<p>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?</p>
