arc-mode.el in the trunk has unrar-free hard-coded. unrar-free is no
longer available in debian testing, and did not work correctly when
it was available in the past. It would be better to use unar/lsar
instead, see http://unarchiver.c3.cx/

Indeed, thanks for bringing it up. Could you provide a patch that does that?

I wish I could, but my lisp skills are almost nil.

I just installed a patch in master to use unar and lsar.
My patch removes the use of the "unrar-free" binary completely as 1) it
is no longer available in Fedora, Ubuntu and Debian and 2) it has been
reported not to work properly, but I guess that's up for discussion.
Cheers,
Nico

According to https://packages.qa.debian.org/u/unrar-free.html,
it's available (again) in Debian.

AFAIK it was working OK, except for the fact that it did not handle all
compression methods supported by the nonfree "unrar".
But since unar works arguably better, it's OK to drop
unrar-free, indeed.
Stefan
PS: Btw, if you're up for some maintenance work on arc-mode.el, there's
a real problem to fix in it: opening a large .zip file (for example) can
take a *very* long time. This time is spent in set-buffer-multibyte
(turning the buffer from unibyte to multibyte) which ends up doing
O(N^2) work. We have a workaround for this problem in auto-coding-alist
where we arrange for those binary files to be loaded directly into
a multibyte buffer (thanks to the no-conversion-multibyte
coding-system), thus avoiding the nasty O(N^2) problem. But a better
solution would be to do what we do in tar-mode.el: rather than keep the
archive's binary data and its user-displayed listing both in the same
buffer, we use two different buffers: a unibyte one containing the
binary data, and a multibyte one displaying the contents.

Given the troubled history of the Free Software programs available to
access RAR archives, and its various format versions, I'd prefer that
we had more than one solution for RAR. Having just one hard-coded
program sounds like a near-term maintenance headache. Other
possibilities include unrar-free, GNA's unrar, and bsdtar from
libarchive. I think we should make this more future-proof. Nicolas,
would you like to work on that?
P.S. Full disclosure: I actually dislike RAR very much, due to its
non-free nature, and wish we've expressed our dislike by not
supporting it at all. But given its widespread use (which I don't
quite comprehend, given the XZ format's performance), I don't expect
that to fly any time soon.

Would adding support for (GNA) unrar be enough for you?
If so, I'll gladly add it.

After having a second look at the GNA unrar download page at
http://download.gna.org/unrar/ it appears that there hasn't been any
release since the 0.0.1 release in 2004, so I'm a lot less sure that
adding support for it in arc-mode would make sense.
libarchive seems to support extracting and listing rar files though, so
I might go with that instead.
