Review request for KDE Utils.


Repository: ark


Description
-------

This patch is based on https://svn.reviewboard.kde.org/r/6730/ (Luke Shumaker <LukeShu at sbcglobal.net>)

This patch will allow Ark to use The Unarchiver command line utilities
(unar/lsar) to operate on RAR files, particularly RARv3.

Now, Ark selects which plugin to use based on MIME type, and the
X-KDE-Priority of the plugin.  Unfortunately, there is currently no
mechanism for a fallback, say one plugin doesn't work, to use
another.  So, for right now users wishing to use Ark with RAR files
must either choose between clirarplugin (which either uses unrar-free
or unrar-nonfree), and cliunarchiverplugin (which uses unar and lsar),
with Ark not being able to just detect which is installed.

To change the X-KDE-Priority, you just need to edit some .desktop
files.  In the source they are
`ark/plugins/*plugin/kerfuffle_*.desktop', which on many systems get
installed to `/usr/share/kde4/services/kerfuffle_*.desktop'. The
plugin with the highest priority is used. The clirarplugin has a
defualt priority of 120, I've given cliunarchiverplugin a priority of
150.  This is probably best set by the package maintainer of an OS;
for example, many systems will prefer unrar-nonfree, but I created
this with Parabola in mind, on which unrar-nonfree does not exist, and
this is the only way that RARv3 files will be opened.

Honestly though, this setup sucks, because unrar-free and unar/lsar
both have their own stengths (basically, unar/lsar suck, but
unrar-free doesn't work on RARv3), and the ideal setup would be to use
unrar-free in most cases, but to fall back to unar/lsar for RARv3
files that unrar-free can't handle.  Actually, I guess the ideal setup
would be to make unar/lsar suck less, or to add RARv3 to rar-free.

=== Known Bugs ===

The program should be able to look at which version of RAR the file
is, but currently doesn't.  (I mean just within lsar) This is simply
because I don't know which field to look at.

=== ChangeLog (Luke Shumaker <LukeShu at sbcglobal.net>)===

00 - Initial patch
01 - Enable clirar, but make cliunarchiver higher priority
02 - Reformat patch
03 - Reformat patch so that ReviewBoard recognizes it

=== Changelog (Andrius Štikonas <stikonas at gmail.com>) ===

04 - new versions of unar can extract password protected files and have
     the ability to extract single files from the archive.
     Make the patch compile with latest git versions of ark.
